Accurate reduction of rotational displacement for transverse or comminute fracture of humeral shaft fracture is difficult during operation. The purpose of this study was to evaluate the reliability of the bicipital groove as a point of reference for the prediction of the rotational state of the humerus on two dimensional images of C-arm image intensifier during operation for humeral shaft fractures.
Materials and Methods:
One hundred subjects, 62 male, 38 female, aged 22-53 years were recruited contralateral bicipital groove on the 45 degrees externally rotational standard anterior-posterior view recorded before surgery. Three observers, watched only contour of bicipital groove in monitor of C-arm image intensification with naked eye without looking at the subject and predicted rotational state of the humerus by comparing the contour of the opposite side of bicipital groove. The angle of discrepancy from real rotational position was then assessed.
The mean (SD), angular discrepancy between the neutral point and the predicted angle was 3.4°(±2.7°). A value within 5° was present in 72% of cases. All observations were within 15°. There was no interobserver variation (P = 0.47). The intraclass correlation coefficient (ICC) was 0.847.
Contour of the bicipital groove on simple radiograph was a useful landmark. Comparing the contour of the bicipital groove in the 45 degrees externally rotational standard view bilaterally, was an effective method for reduction of rotational displacement of the humerus.

Flexor tendon injuries are seen commonly yet the management protocols are still widely debated. The advances in suture techniques, better understanding of the tendon morphology and its biomechanics have resulted in better outcomes. There has been a trend toward the active mobilization protocols with development of multistrand core suture techniques. Zone 2 injuries remain an enigma for the hand surgeons even today but the outcome results have definitely improved. Biomolecular modulation of tendon repair and tissue engineering are now the upcoming fields for future research. This review article focuses on the current concepts in the management of flexor tendon injuries in zone 2.

Congenital pseudarthrosis of the tibia (CPT) is a rare pathology, which is usually associated with neurofibromatosis type I. The natural history of the disease is extremely unfavorable and once a fracture occurs, there is a little or no tendency for the lesion to heal spontaneously. It is challenging to treat effectively this difficult condition and its possible complications. Treatment is mainly surgical and it aims to obtain a long term bone union, to prevent limb length discrepancies, to avoid mechanical axis deviation, soft tissue lesions, nearby joint stiffness, and pathological fracture. The key to get primary union is to excise hamartomatous tissue and pathological periosteum. Age at surgery, status of fibula, associated shortening, and deformities of leg and ankle play significant role in primary union and residual challenges after primary healing. Unfortunately, none of invasive and noninvasive methods have proven their superiority. Surgical options such as intramedullary nailing, vascularized fibula graft, and external fixator, have shown equivocal success rate in achieving primary union although they are often associated with acceptable results. Amputation must be reserved for failed reconstruction, severe limb length discrepancy and gross deformities of leg and ankle. Distinct advantages, complications, and limitation of each primary treatment as well as strategies to deal with potential complications have been described. Each child with CPT must be followed up till skeletal maturity to identify and rectify residual problems after primary healing.

Despite new developments in the management of osteoporotic fractures, complications like screw cutout are still found in the fixation of proximal femur fractures even with biomechanically proven better implants like proximal femoral nail antirotation (PFNA). The purpose of this cadaveric study was to investigate the biomechanical stability of this device in relation to two common positions (center-center and inferior-center) of the helical blade in the femoral head in unstable trochanteric fractures.
Materials and Methods:
Eight pairs of human cadaveric femurs were used; in one group [center-center (C-C) group], the helical blade of PFNA was fixed randomly in central position both in anteroposterior and lateral view, whereas in the other group it was fixed in inferior one-third position in anteroposterior and in central position in lateral view [inferior-center (I-C) group]. Unstable intertrochanteric fracture was created and each specimen was loaded cyclically till load to failure
Angular and rotational displacements were significantly higher within the C-C group compared to the I-C group in both unloaded and loaded condition. Loading to failure was higher in the I-C group compared to the C-C group. No statistical significance was found for this parameter. Correlations between tip apex distance, cyclic loading which lead to femoral head displacement, and ultimate load to failure showed a significant positive relationship.
The I-C group was superior to the C-C group and provided better biomechanical stability for angular and rotational displacement. This study would be a stimulus for further experimental studies with larger number specimens and complex loading protocols at multicentres.

Duration of treatment in tuberculosis of spine has always been debatable in the absence of marker of healing. The objective of the study was to evaluate the efficacy of extended DOTS regimen (2 months of intensive phase and 6 months of continuation phase) as recommended by WHO, by using MRI observations as the healing marker.
Materials and Methods:
51 (Group A -28 prospective and Group B- 23 retrospective) patients of spine TB with mean age of 26.8 years (range 15-54 years) diagnosed clinico radiologically/imaging (n=36), histopathology or by PCR (n=15) were enrolled for the study. They were treated by extended DOTS regimen (2 months of HRZE and 6 months of HR) administered alternate day. The serial blood investigations and X-rays were done every 2 months. Contrast MRI was done at the end of 8 months and healing changes were recorded. Criteria of healing on the basis of MRI being: complete resolution of pre and paravertebral collections, resolution of marrow edema of vertebral body (VB), replacement of marrow edema by fat or by calcification suggested by iso- intense T1 and T2 weighted images in contrast enhanced MRI. Patients with non healed status, but, responding lesion on MRI after 8 months of treatment were continued on INH and rifampicin alternate day and contrast MRI was done subsequently at 12 months and 18 months till the healed status was achieved .
9 patients had paraplegia and required surgical intervention out of which 1 did not recover neurologically. All patients have completed 8 months of extended DOTS regimen, n=18 achieved healed status and duration of treatment was extended in rest (n=33) 5 were declared healed after 12 months, 8 after 18 months and one after 36 months of treatment, thus 32 were declared healed at varying periods.
35.2% patients demonstrate MRI based healed vertebral lesion at the end of 8 months of extended category 1 DOTS regimen. It is unscientific to stop the ATT by fixed time frame and MRI evaluation of the patients is required after 8 months of ATT and subsequently to decide for the continuation stoppage of treatment.

Dynamic hip screw (DHS) has been the standard treatment for stable trochanteric fracture patterns, but complications of lag screw cut out from a superior aspect, due to inadequate bone anchorage, occur frequently in elderly osteoporotic patients. Polymethylmethacrylate (PMMA) has been used as an augmentation tool to facilitate fixation stability in cadaveric femora for biomechanical studies and in pathological fractures. However, there are very few reports on the utilization of PMMA cement to prevent these complications in fresh intertrochanteric fractures. A prospective study was conducted to evaluate the outcome and efficacy of PMMA augmented DHS in elderly osteoporotic patients with intertrochanteric fractures.
Materials and Methods:
The study included 64 patients (AO type31-A2.1 in eight, A2.2 in 29, A2.3 in 17 patients, and 31-A3.1 in five, A3.2 in three, and A3.3 in two patients) with an average age of 72 years (60 – 94 years) of which 60 were available for final followup. PMMA augmentation of DHS was performed in all cases by injecting PMMA cement into the femoral head with a custommade gun designed by the authors. The clinical outcome was rated as per the Salvati and Wilson scoring system at the time of final followup of one year. Results were graded as excellent (score > 31), good (score 24 – 31), fair (score 16 – 23), and poor (score < 16).
Fracture united in all patients and the average time to union was 13.8 weeks (range 12 – 16 weeks). At an average followup of 18 months (range 12 – 24 months), no incidence of varus collapse or superior screw cut out was observed in any of the patients in spite of weightbearing ambulation from the early postoperative period. There was no incidence of avascular necrosis (AVN) or cement penetration into the joint in our series. Most of the patients were able to regain their prefracture mobility status with a mean hip pain score of 8.6.
Cement augmentation of DHS appears to be an effective method of preventing osteoporosis related complications of fracture fixation in the trochanteric fractures. The technique used for cement augmentation in the present study is less likely to cause possible complications of cement augmentation like thermal necrosis, cement penetration into the joint, and AVN hip.

Optimal pain treatment with minimal side effects is essential for early mobility and recovery in patients undergoing total knee arthroplasty (TKA). We investigated the effect of pregabalin as an adjuvant for postoperative analgesia provided by opioid-based patient-controlled epidural analgesia (PCEA) in such patients.
Materials and Methods:
Forty patients undergoing unilateral primary TKA were randomly assigned to two equal groups, to receive either placebo or pregabalin 75 mg twice a day. The drug was administered orally starting before surgery and was continued for 2 days after surgery. Anesthetic technique was standardized. Postoperatively, static and dynamic pain was assessed by verbal rating score. Mean morphine consumption, PCEA usage, rescue analgesic requirement, and overall patient satisfaction were also assessed. Treatment emergent adverse drug reactions were recorded.
Mean morphine consumption was significantly reduced by pregabalin. Postoperative pain (both static and dynamic) and PCEA consumption too was significantly reduced in the pregabalin group during the first 48 h after surgery. This group needed fewer rescue analgesics and recorded higher overall patient satisfaction. Pregabalin-treated patients had fewer opioid-related adverse reactions like nausea, vomiting, and constipation. Dizziness was noted in two of the patients receiving pregabalin. There was no statically significant difference in the incidence of sedation in the two groups.
Oral pregabalin 75 mg started preoperatively is a useful adjunct to epidural analgesia following TKA. It reduces opioid consumption, improves postoperative analgesia, and yields higher patient satisfaction levels.

Gap nonunion that may occur following trauma or infection is a challenging problem to treat. The patients with intact or united fibula, preserved sensation in the sole, and adequate vascularity, were managed by tibialization (medialization) of the fibula (Huntington's procedure), to restore continuity of the tibia. The goal of this retrospective analysis study is to report the mid-term results following the Huntington's procedure.
Materials and Methods:
22 patients (20 males and two females) age 16-34 years with segmental tibial loss more than 6 cm were operated for tibialization of fibula. The procedure was two-staged in seven and single-staged in the rest 15 patients, where the lateral aspect of the leg was relatively supple. In the two-staged procedure, the distal tibiofibular synostosis was performed six-to-eight weeks after the proximal procedure. Weightbearing (protected) was started in a long leg cast after six-to-eight weeks of the second stage and continued for six-to-eight months, followed by the use of a brace.
The fibula started showing signs of hypertrophy within the first year after the procedure and it was more than double in breath after the four-year period. Full and unprotected weightbearing on the operated leg was achieved at an average time of 16 months. At the final followup, ten patients were very satisfied, seven satisfied, and five fairly satisfied. One patient had persistent nonunion at the proximal synostotic site even after bone grafting and secondary fixation.
Huntington's procedure is a safe and simple salvage procedure and remains an excellent option for treating difficult infected nonunion of the tibia in the selected indications.

Posterior heel pain due to retrocalcaneal bursitis, is a disabling condition that responds well to the conventional methods of treatment. Patients who do not respond to conservative treatment may require surgical intervention. This study evaluates the outcome of endoscopic decompression of retrocalcaneal bursitis, with resection of posterosuperior eminence of the calcaneum.
Materials and Methods:
This present study included 25 heels from 23 consecutive patients with posterior heel pain, who did not respond to conservative treatment and underwent endoscopic decompression of the retrocalcaneal bursae and excision of bony spurs. The functional outcome was evaluated by comparing the pre and postoperative American Orthopedic Foot and Ankle Society (AOFAS) scores. The Maryland ankle and foot score was used postoperatively to assess the patient's satisfaction at the one-year followup.
The University of Maryland scores of 25 heels were categorized as the nonparametric categories, and it was observed that 16 patients had an excellent outcome, six good, three fair and there were no poor results. The AOFAS scores averaged 57.92 ± 6.224 points preoperatively and 89.08 ± 5.267 points postoperatively (P < 0.001), at an average followup of 16.4 months. The 12 heels having noninsertional tendinosis on ultrasound had low AOFAS scores compared to 13 heels having retrocalcaneal bursitis alone. At one year followup, correlation for preoperative ultrasound assessment of tendoachilles degeneration versus postoperative Maryland score (Spearman correlation) had shown a strong negative correlation.
Endoscopic calcaneal resection is highly effective in patients with mild or no degeneration and yields cosmetically better results with fewer complications. Patients with degenerative changes in Achilles tendon had poorer outcomes in terms of subjective satisfaction.

Proximal humerus fracture in elderly osteoporotic patients usually leads to severe displaced and multifragmentary fractures. Associated comorbidities may limit surgical options and conservative treatment is commonly indicated, however, with variable results. In most cases, surgery is the treatment of choice in order to restore anatomical integrity, and allow early functional recovery. Several techniques were used over the years, each with specific indication. Percutaneous pinning after closed reduction, a mini-invasive technique and fixation by use of K-wires is not preferred commonly. We present our experience with this approach, focusing on its indications and advantages.
Patients and Methods:
A study group of 41 consecutive patients with a mean age of 65.5 years were evaluated clinically (VAS, Constant-Murley score, range of motion), and with radiological analysis: 35 patients finally completed a minimum followup of 24 months.
K-wires were removed after a mean interval of 4 weeks. Clinical and radiographic healing occurred in a mean time of 8.2 weeks in all fractures but one, with improvements in mean Constant-Murley score of 87.6 points, mean VAS of 2.3. In 33 patients, the reduction was considered satisfactory. In two cases, reduction was poor, but the patients however presented acceptable functional outcome.
Percutaneous pinning may represent a suitable option of treatment for 2-or 3-part proximal humerus fractures in selected subjects.

The Bankart lesion represents the most common form of labro-ligamentous injury in patients with traumatic dislocations of the shoulder leading to shoulder instability. We report the clinical outcome of arthroscopic repair of Bankart lesion in 50 patients.
Materials and Methods:
Sixty five patients with posttraumatic anterior dislocation of shoulder were treated by arthroscopic repair from Jan 2005 to Nov 2008. Fifty patients, with an average age of 26.83 years (range 18-45 years), were reviewed in the study. The average followup period was 27 months (range 24-36 months). University of California Los Angeles shoulder rating scale was used to determine the outcome after surgery. The recurrence rates, range of motion, as well as postoperative function and return to sporting activities were evaluated.
Thirty six patients (72.0%) had excellent results, whereas seven patients (14.0%) had good results. The mean pre- and postoperative range of external rotation was 80.38° and 75.18°, respectively. Eighty-six percent patients had stability compared with the normal sided shoulder and were able to return to sports. There were no cases of redislocation observed in this study; however, three cases had mild laxity of the joint.
Arthroscopic Bankart repair with the use of suture anchors is a reliable treatment method, with good clinical outcomes, excellent postoperative shoulder motion and low recurrence rates.

Treatment of complex injuries of interphalangeal joints (IPJs) is difficult. The restoration of joint stability for early joint mobility till fracture union is the key for successful outcome. Although various treatment options like dynamic splinting, external fixator, closed reduction, transarticular Kirschner (K)-wire and ORIF, etc., are available in literature, a universally accepted ideal treatment for complex intraarticular fractures of IPJs is still evolving. Open reduction is difficult because fixation of volar fragment is often impractical and radical procedures like volar plate arthroplasty, arthrodesis or joint replacement, etc., may become mandatory for salvage. We describe percutaneous technique to treat unstable fractures and dorsal fracture–dislocations of the PIP joint and report short-term postoperative results.
Materials and Methods:
Ten cases of unstable or potentially unstable intraarticular fractures including pilon fractures and fracture-dislocations of IP joints were treated percutaneously by double parabolic K-wire technique (DPK). The device was used as a dynamic distraction, using the principle of ligamentotaxis. The idea was to commence early postoperative continuous active and active-assisted joint motion exercises and to carry on the frame as a definitive treatment for achieving fracture union.
In all patients of fracture-dislocation the reduction was satisfactory and early mobility was achieved. Although there is a tendency towards over-distraction, no loss of reduction occurred. Pin tract infection occurred in one with no delayed union or nonunion. The average total range of motion for each involved IP joint was 93.5 degree and the average total active range of motion was 90.8° each at the end of 4 months followup. Excellent to good results were restored in nearly all cases without further interventions.
DPK technique may be a cheap and valuable definitive treatment option in the management of unstable or potentially unstable intraarticular fractures of IPJs. The technique gave satisfactory radiological union and functional outcome in our small series. This technique may be worth considering in unstable or potentially unstable intraarticular fractures of IPJs with intact collateral ligaments and when other treatment options are impractical.

Radial bone loss associated with gross manus valgus deformity can be managed by open reduction internal fixation using intervening strut bone graft, callus distraction using ring or monoaxial fixator, and achieving union by distraction histogenesis. These methods are particularly suitable when bone loss is small. Single or staged procedure is described for congenital as well as in acquired extensive bone loss of radius. Distraction through radial proximal to distal segments, to achieve reduction of distal radio-ulnar joint (DRUJ), is also described in acquired cases. In the present series, functional results of distraction through ulna to 2nd metacarpal is studied alongwith, functional status of hand, stability of wrist, level of patient's satisfaction are also studied.
Materials and Methods:
7 unilateral cases of radial loss (M = 5, F = 2) affecting 4 right hands of mean age 17 years (range 9 to 24 years) were included in this study. They were treated by distracting through ulna to 2nd metacarpal to achieve DRUJ alignment in first stage. Subsequently ulna was osteotomised and translated to distal stump of radius. It was then fixed to the distal radial remnant in 30° pronation in dominant and 30° supination non dominant hands.
Union was achieved in all cases associated with beneficial cross union of distal ulna. Hand functions improved near to normal, with fully corrected stable wrist joint, hypertrophied ulna and without recurrence. All of them had practically complete loss of forearm rotations, however patients were fully satisfied.
This method is particularly suitable when associated with 6 cm or more radial bone loss. But when loss is small, sacrifice of one bone may not be justifiable.

Loss of reduction following closed or open reduction of displaced supracondylar fractures of the humerus in children varies widely and is considered dependent on stability of the fracture pattern, Gartland type, number and configuration of pins for fixation, technical errors, adequacy of initial reduction, and timing of the surgery. This study was aimed to evaluate the factors responsible for failure of reduction in operated pediatric supracondylar fracture humerus.
Materials and Methods:
We retrospectively assessed loss of reduction by evaluating changes in Baumann's angle, change in lateral rotation percentage, and anterior humeral line in 77 consecutive children who were treated with multiple Kirschner wire fixation and were available for followup. The intraoperative radiographs were compared with those taken immediately after surgery and 3 weeks postoperatively. Multivariate logistic regression analysis was performed by STATA 10.
Reduction was lost in 18.2% of the patients. Technical errors were significantly higher in those who lost reduction (P = 0.001; Odds Ratio: 57.63). Lateral pins had a significantly higher risk of losing reduction than cross pins (P = 0.029; Odds Ratio: 7.73). Other factors including stability of fracture configuration were not significantly different in the two groups.
The stability of fracture fixation in supracondylar fractures in children is dependent on a technically good pinning. Cross pinning provides a more stable fixation than lateral entry pins. Fracture pattern and accuracy of reduction were not important factors in determining the stability of fixation.

Late presentation of humeral lateral condylar fracture in children is a surgical dilemma. Osteosynthesis of the fracture fragment or correction of elbow deformity with osteotomies and ulnar nerve transposition or sometimes both procedures combined is a controversial topic. We retrospectively evaluated open reduction and fixation cases in late presentation of lateral humeral condyle fracture in pediatric cases with regards to union and functional results.
Materials and Methods:
Twenty two pediatric (≤12 years) patients with fractures of lateral condyle presenting 4 weeks or more post injury between the study period of 2006 and 2010 were included. Multiple K-wires / with or without screws along with bone grafting were used. At final evaluation, union (radiologically) and elbow function (Liverpool Elbow Score, LES) was assessed.
There were 19 boys and 3 girls. Followup averaged 33 months. Pain (n=9), swelling (n=6), restriction of elbow motion (n=6), prominence of lateral condylar region (n=4), valgus deformity (n=4) were the main presenting symptoms. Ulnar nerve function was normal in all patients. There were nine Milch type I and 13 type II fractures. Union occurred in 20 cases. One case had malunion and in another case there was resorption of condyle following postoperative infection and avascular necrosis. Prominent lateral condyles (4/12), fish tail appearance (n=7), premature epiphyseal closure (n=2) were other observations. LES averaged 8.12 (range, 6.66-9.54) at final followup.
There is high rate of union and satisfactory elbow function in late presenting lateral condyle fractures in children following osteosynthesis attempt. Our study showed poor correlation between patient's age, duration of late presentation or Milch type I or II and final elbow function as determined by LES.

Slipped capital femoral epiphysis (SCFE) is a disorder of adolescent age. Presentation of SCFE earlier than the expected age range should prompt the clinician to consider the presence of an underlying endocrinopathy. Early recognition and aggressive management of the predisposing endocrine disorder is crucial to prevent treatment failure and associated morbidity. We report the clinical presentation and treatment of an 8-year-old girl with bilateral slipped capital femoral epiphysis. The unusual age, persistent hypocalcemia, and associated distal femoral physeal deformities prompted further evaluations, which led to the diagnosis of pseudohypoparathyroidism type 1b. PHP type 1b is an extremely rare cause of SCFE and only a few cases have been reported. A delay in diagnosis in such case is not uncommon.

Unstable spine fractures commonly occur in the setting of a polytraumatized patient. The aim of management is to balance the need for early operative stabilization and prevent additional trauma due to the surgery. Recent published literature has demonstrated the benefits of early stabilization of an unstable spine fracture particularly in patients with higher injury severity score (ISS). We report two cases of polytrauma with unstable spine fractures stabilized with a minimally invasive percutaneous pedicle screw instrumentation system as a form of damage control surgery. The patients had good recovery from the polytrauma injuries. These two cases illustrate the role of minimally invasive stabilization, its limitations and technical pitfalls in the management of unstable spine fractures in the polytrauma setting as a form of damage control surgery.

We report a case of isolated ossification of iliopsoas with ankylosis of the left hip in a 27-year-old female. The patient was diagnosed to have Moyamoya disease, a rare chronic occlusive disorder of cerebrovascular circulation following an acute onset of hemiplegia. The patient presented 9 months later to us with ankylosis of left hip which was successfully treated by surgical excision of the heterotopic bone and there was no recurrence at the end of 5 years. A review of literature failed to reveal a similar case with isolated and complete ossification of iliopsoas muscle associated with Moyamoya disease which required surgical intervention. Surgical excision resulted in dramatic improvement in the quality of life. Surgical excision of neurogenic type of heterotopic ossification is a very successful procedure and timely intervention after maturity of mass is very important to prevent the onset of secondary complications and to avoid recurrence.

87-year-old female underwent open reduction of distal femoral fracture and internal fixation with locking compression plate and bone graft. She was operated for ipsilateral proximal femoral fractures and stabilized by intramedullary interlocked nail 5 years ago. She developed stress fracture proximal to locked plate. We inserted Huckstep nail after removal of the previous operated proximal femoral nail without removing the remaining plate and screws. At 15 month followup the fractures have united. The Huckstep nail has multiple holes available for screw fixation at any level in such difficult situations.

Bipolar dislocation of the clavicle at acromioclavicular and sternoclavicular joint is an uncommon traumatic injury. The conservative treatments adopted in the past is associated with redislocation dysfunction and deformity. A 41 years old lady with bipolar dislocation of right shoulder is treated surgically by open reduction and internal fixation by oblique T-plate at sternoclavicular joint and Kirschner wire stabilization at acromioclavicular joint. The patient showed satisfactory recovery with full range of motion of the right shoulder and normal muscular strength. The case reported in view of rarity and at 2 years followup.

The high-pressure injection injuries are unusual injuries and the extent of tissue damage is often under estimated. They represent potentially disabling forms of trauma and have disastrous effects on tissues if not treated promptly. We present a case of high pressure injection injury to the finger from lubricant oil. The patient presented late with necrosis of volar tissue of left index finger. The patient was aggressively managed in stages, with delayed flap cover, with satisfactory functional and aesthetic outcome.
