Abstract
This was a prospective case series involving 15 patients (10 males, 5 females) with comminuted proximal ulnar fracture treated with open reduction and internal fixation using either precontoured 3.5 reconstruction plate or anatomical locked plate. Their mean age was 39.73 years. Twelve fractures were classified as 21-B1, 2 as 21-A1 & 1 fracture as 21-B3 according to the AO/OTA classification and 7 of them were open. The mean follow up period was 4 months. Patients were assessed clinically using Mayo elbow performance score (MEPS) and radiographically. Results: At the time of our final follow up no hardware failure or fracture displacement were recorded. 93.3% of patients united and 6.6% required secondary grafting. The average range of motion was 106{u00B0} ±19.57{u00B0} and the mean MEPS was 87.67 ± 13.61. 86% of cases achieved excellent or good functional outcome and 12.5% required secondary procedures. Conclusion: Anatomically preshaped LCP olecranon plating is an effective fixation method for comminuted fractures of the proximal ulna allowing reliable stability for early elbow motion. The functional results are comparable with formerly described plating systems. A low rate of symptomatic hardware removal suggests better patient{u2019}s compatibility. We recommend its use in fixation of proximal ulnar fractures as it is safe and effective. Level of evidence: Therapeutic level IV
