Closed reduction and lateral-entry pin fixation in the management of displaced supracondylar humeral fractures in children: reduction stability and iatrogenic nerve injuries Background: Closed reduction and percutaneous pin fixation has been the treatment of choice for displaced supracondylar humeral fractures in children in Hospital for Traumatology and Orthopedics, Ho Chi Minh City for nearly a decade, although controversy persists regarding the optimal pin-fixation technique: lateral-entry pin fixation or medial and lateral entry pin fixation. The purpose of this study was to evaluate the efficacy of lateral entry pin fixation in terms of reduction stability and iatrogenic nerve injuries.

The purpose of this study was to evaluate the efficacy of lateral entry pin fixation in terms of reduction stability and iatrogenic nerve injuries. Methods In this retrospective clinical study we reviewed 17 cases of displaced supracondylar humeral fractures in children which were managed by the lateral-entry pin fixation. We examined fracture classification pin configuration radiographic findings taken immediately after operations and at 3-week follow-up appointment. The clinical carrying angle was measured for the cases affected by loss of reduction. Preoperative and postoperative neurologic evaluations were performed to discover nerve injuries associated with the treatment. Results There were 17 cases reviewed range 20 months to 14 years included 2 cases of type II and 15 cases of type III displacement. There were 2 cases of loss of reduction with identifiable technical errors failure to engage both osseous columns and failure to achieve adequate pin separation at the fracture site. Two cases of radial nerve paralysis were noted postoperatively. Conclusions Loss of reduction following pin fixation of supracondylar humeral fractures in children occurred with identifiable technical errors. Lateral entry pin fixation is less likely to occur when Gartland type III fractures were treated with three lateral-entry pins. Postoperative radial nerve injuries were reported in two cases.
