6-Pin Technique Joshi External Stabilization System Fixation for Proximal Humerus Fractures – A Case Series

INTRODUCTION: Proximal humerus fractures account for 4–5% of the fractures in long bones with a bimodal distribution. A wide spectrum of options are available in its management ranging from conservative to total shoulder replacement. We aim to demonstrate a minimally invasive simple 6-pin technique in the management of proximal humerus fracture using Joshi external stabilization system (JESS). CASE REPORT: We report the results of ten patients (M: F = 4:6) with proximal humerus fractures of age range between 19 and 88 years managed with the 6-pin technique JESS under regional anesthesia. Of the included patients, 4, 3, and 3 cases belonged to Neer Type II, III, and IV, respectively. On analysis of outcomes based on the Constant-Murley score, we noted excellent outcomes and good outcomes in 6 (60%), and 4 (40%) patients, respectively, at 12 months. Fixator was removed after the radiological union between 8 and 12 weeks. Complications noted include pin tract infection in 1 (10%) and malunion in 1 (10%) case. CONCLUSION: JESS fixation by 6-pin technique remains a viable minimally invasive cost-effective treatment option in the management of proximal humerus fractures.
