Tibial diaphyseal fracture is the commonest long bone fracture due to its anatomical location and subcutaneous nature. Tibial interlocking nailing is the treatment of choice for this fracture. This procedure is often performed with image intensifier guidance; however, external jig open technique is a cheap and feasible option in resource poor setting where image intensifier may not be available. There is no locally relevant assessment on the outcome of this procedure that is commonly performed. The objective of the present research was to describe the pattern of presentation and evaluate early clinical and radiologic outcome of tibial diaphyseal fracture using open locked intramedullary tibial nailing technique. Upon concluding the study, the conclusion was made that open external jig aided interlocking intramedullary tibial nailing produces good to excellent outcome with acceptable complication rate.
