Treatment of diaphyseal forearm fracture with interlocking intramedullary nailing: A pilot study.

INTRODUCTION: The present study was done to assess the functional outcome and complications of interlocking intramedullary (IM) radius ulna nailing to treat radio-ulna fractures in adults. METHODOLOGY: Thirty adult patients with diaphyseal or segmental fractures of radius and ulna were included and treated with IM nailing. Grace and Eversmann rating system was used to assess functional evaluation and grip strength was measured using grasp dynamometer. RESULTS: Mean age of the 30 eligible patients was 33.5 years, and males comprised 77% of the study population. Intra-operative complications like nail impaction and proximal screw locking problem for radius was present in one patient each. Increased swelling in three patients (10%) and posterior interosseous nerve palsy in one patient (3%) were observed post-operatively. In the post-operative period, all patients were able to move fingers, had 100° elbow range of motion and good grip strength. Pronation and supination till 80° was present in 80% and 57% of the patients respectively. Wrist flexion and dorsiflexion till 90° was present in 80% and 57% of the patients. Fracture union was confirmed radiologically in all cases at a mean of 3.6 weeks. Functional outcome was excellent in 73% and good in 13%. Grip strength was judged to be excellent in all cases. CONCLUSIONS: Excellent and good functional outcomes were obtained in 86%, and no case developed mal-union or delayed union. Based on our results, IM nail for surgical treatment of radial and ulnar diaphyseal fractures can be used.
