Abstract
INTRODUCTION AND IMPORTANCE: Plastic deformities usually occur in skeletally immature bones not completely ossified due to longitudinal forces on their distal ends, especially the forearm and lower legs. Pediatric lateral humeral condylar fractures (LHCFs) constitute the second most common intra-articular fracture in the upper extremity. Nevertheless, plastic deformities accompanied by other traumatic injuries, including LHCFs, are atypical and rare. This study presents an exceedingly rare case of the concurrence of a plastic deformity and an ipsilateral fracture of the lateral condyle of the humerus in a 6-year-old Persian boy. CASE PRESENTATION: The 6-year-old Persian injured boy referred to orthopedic clinic with an obvious deformity in the right upper limb with a limited motion range in the ipsilateral elbow. The patient underwent open-fixation surgery for LHCF fixation and suitable maneuvers to rectify the ulnar plastic deformity. Our findings indicated an acceptable outcome for this approach. His injured limb was reformed without deformities, and the complete union of the fractured area was accomplished eight weeks after surgery. CLINICAL DISCUSSION: The case is remarkable as reminding that we have to care concomitant "minor" injuries to the main fracture and to correctly treat them. Furthermore, open fixation surgery for LHCF rectification before fixing the ulnar deformity with the aid of a suitable maneuver led to good outcome and acceptable rehabilitation in a case of concurrent ulnar plastic deformity and an ipsilateral fracture of the external condyle of the humerus. CONCLUSION: Our approach helps to avoid further tissue damage and prevent the 2-stage surgical process.
