Abstract

Introduction: The imperfect treatment of fractures of radius and ulna diaphyses leads to a loss of motion as well as muscle imbalance and poor hand function. Therefore, the present study was designed to evaluate the functional outcome of interlock intramedullary fixation in the fracture forearm bones.
Materials and Methods: Thirty two patients included after their consent. With the patient supine on a radiolucent table, and under general or regional anaesthesia the extremity was prepared and the surgery was performed using a standard procedure. If secure rigid fixation is required forearm POP splint is applied and kept in place for 2 weeks, thereafter a removable sugar-tong orthosis was worn until bridging callus is present, and the orthosis is removed frequently for exercise. Evaluation was done using DASH score and Grace and Eversman score. Grace & Eversmans score was based on the union of the fracture and rotation of the forearm as Excellent, Good, Acceptable and Unacceptable.
Results: There was statistically significant difference in the surgical time (P<0.05) and duration of post-operative immobilization differed statistically significantly (P<0.001) between the group of patients in whom locking was done and not done. The average DASH score was 9.95 and functional outcome of the patients undergone interlock nailing was excellent and good in 40.91% of patients whereas not acceptable in 4.54% of patients as per Grace and Eversmann score.
Conclusion: Complex fracture pattern like C type injuries were stabilized in an elegant manner without additional damage to soft tissues. This suggests that, interlock nailing provided cosmetically better suited and little risk of refracture after removal of the implant.
