The management of pink pulseless limbs in supracondylar fractures has remained controversial, especially with regards to the indication for exploration in a clinically well-perfused hand. We reviewed a series of seven patients who underwent surgical exploration of the brachial artery following supracondylar fracture. All patients had a non-palpable radial artery, which was confirmed by Doppler ultrasound. CT angiography revealed complete blockage of the artery with good collateral and distal run-off. Two patients were more complicated with peripheral nerve injuries, one median nerve and one ulnar nerve. Only one patient had persistent arterial constriction which required reverse saphenous graft. The brachial arteries were found to be compressed by fracture fragments, but were in continuity. The vessels were patent after the release of obstruction and the stabilization of the fracture. There was no transection of major nerves. The radial pulse was persistently present after 12 weeks, and the nerve activity returned to full function.

The incidence of brachial artery injury is not uncommon in supracondylar fractures. The risk has been reported at only 1%; however, recent studies noted an increase in vascular injury risks ranging from 12-15% 1,2. Vascular insufficiency that requires immediate surgical intervention is rare. The management of a pulseless well-perfused hand remains debatable and, to date, no consensus on management exists. Defensive strategy with closed observation had been advocated, however, some recommended early surgical exploration within the first 48 hours if pulselessness remains or compartment syndrome is evident. Reported complications of Volkmann contracture and loss of limb is low, yet it is still very important to clinically identify to prevent unnecessary and debilitating complications3.

Materials and Methods

This is a retrospective study conducted from January 2011 to January 2016 on patients who were surgically treated for supracondylar humeral fracture with absence of radial pulse in a single institution. All seven patients had good hand circulation, but absent radial pulses were clinically evaluated and confirmed using Doppler signal. The brachial artery was explored in all patients, and fractures were finally stabilized with K-wires.

In this study, we reviewed the clinical presentation, injury pattern, CT angiography, and surgical findings at exploration of brachial artery. The final outcome was evaluated and relevant findings are presented.


There were five males and two females with the mean age of 8.5 years-old (range 2-15 years). Extension type of fractures were noticed in all seven cases, and nerve injuries were associated in two. Radial pulse was not present in all patients, and an absent signal was confirmed on Doppler. The CT angiography revealed that four patients had a complete block but with the presence of collateral and distal run-off (Table I). All patients underwent exploration and release of brachial artery and K-wire stabilization of fracture through the anterior approach. The brachial artery was found compressed by proximal fragment fractures in all patients. The distal pulses returned to normal after the reduction and stabilization of the fracture, as well as the superficial adventitia release of contused segment arteries. Initial spasms of arteries were managed by the local application of verapamil or lignocaine (Fig. 1 - Case 7). The decision for reverse saphenous graft was made in one case for brachial artery constriction and contusion, in which the distal flow did not recover through local intervention (Fig. 2 - Case 6). The median time taken for the reestablishment of the pulse was 24 hours (range between 3-96 hours) with the mean absence of pulse to 31.4 hours. All supracondylar humeral fractures were stabilized by 1.6-1.8mm crossed K-wires. One patient had earlier undergone closed reduction and stabilization in another center, but the hand was subsequently pulseless. The CT angiograms revealed brachial artery block with good distal run-off. An immediate surgical exploration and release restored the arterial flow and distal pulses (Fig. 3 - Case 1). Median nerve injury and ulnar nerve palsy noted preoperatively were explored. Both nerves were contused and remained in continuity.

Radial pulses were palpable, with pink and warm hands postoperatively in all seven patients and on discharge, and during follow-up. K-wires were retained for three weeks and fracture union was achieved after six weeks in all patients. No ischemic contracture was noted during the follow-up, and all patients with neurological deficit had fully recovered after at least six weeks post injury.


The management of pink pulseless hand in supracondylar fracture has long been controversial, especially in regard to the indication for exploration of the brachial artery in a clinically well-perfused full motor function hand. Griffith et al, in a literature review, concluded that the management depended largely upon clinical findings. A child with a pink pulseless hand following successful reduction could be managed conservatively. However, whenever additional signs of ischemia develop, surgical exploration was required4. A meta-analysis study by White et al concluded that absence of pulse after supracondylar humerus fracture is a strong indicator of vascular injury. Collateral circulation around the elbow can be variable and unreliable. Brachial artery revascularization in children can be successfully accomplished and has been associated with high success rate. Thus, the authors recommended an aggressive approach to absence of pulse by exploration and repair, as it is an indicator of vascular compromise, and the success rate for revascularization is sufficiently high. In contrast, Weller et al stated that in a pink pulseless hand, after closed reduction and stabilization, it is not an indication for vascular exploration provided the limb is well perfused. Close observation is mandatory to look for signs of deterioration5. A review questionnaire study of pediatrics orthopedic surgeons by Malviya et al revealed that only 16.1% of surgeons would proceed with exploration of vessels if pulses remain absent after stabilization6. The targeted vessels are often a few millimeters in diameter, and if they need surgical reconstruction, this requires microsurgical expertise. Furthermore, exploration carries the risk of injury to collateral vessels to maintain a viable extremity. Complications of symptomatic re-occlusion and residual stenosis are relatively high7. We explored all cases with loupe magnification and strict care was taken to not explore beyond levels of collaterals. The vessel reconstruction in an established thrombosed patient was performed under a microscope with a microsurgical expert. A recent paper by Louahem et al reviewed 68 pink pulseless hands of 404 Gartland III cases, and recommended urgent closed reduction of fracture followed by close monitoring. Circulation disturbances warranted immediate vascular exploration8.

Long-term late sequelae of ischemic forearm were reported by Blakey et al who suggested a more aggressive management to prevent major disability3. Recently, POSNA also recommended a more aggressive vascular intervention approach. Reviews further suggest a more aggressive vascular evaluation and exploration in selected cases2.

Luria et al reported 24 cases of supracondylar humerus fracture with vascular compromise. Out of 22 cases, immediate return of radial pulse was noted in 11 cases, and no return of pulses in another 11, after closed reduction and K-wiring. The patients without a return of pulse underwent primary exploration, and eight of them were found to have a tear or entrapment of the brachial artery9. Based on our findings, primary exploration without initial manipulation of six cases, only one case required vascular graft. We believe that improper attempt of closed reduction may further injure the vessels and lead to significant damage. Thus, it is safer to release the bony compression through exploration and open reduction. Our present study revealed that most cases can be managed by exploration and release of the vessels from the fracture site, thus returning the pulses and minimizing late complications of vascular injuries. The kinked vessels in children have shown to be more resistant to acute thrombosis, even though exploration was delayed with the mean duration of 24 hours. Only one patient required bypass graft due to acute thrombosis.

Nerve injury is also taken into consideration for immediate exploration of pulseless limbs. According to Luria et al, a significant correlation was found between median nerve deficit and vascular injury 9. Ramachandran suggested that coexisting ischemia is an indication for vascular exploration10. Mangat et al recommended early exploration of Gartland III supracondylar fracture in patients with coexisting anterior interosseous, or median nerve palsy, since these appear as a strong predictive indicator of nerve and vessel entrapment11. Both our cases showed complete recovery at about six weeks, indicating that the lesion was neuropraxia.

In conclusion, early exploration, open vascular release, and fracture reduction are options of treatment for pink pulseless hands in supracondylar fractures in children to maintain vessel patency.
