A comparative study of extra-articular distal tibia fractures managed by intramedullary nailing vs locking plate

Abstract

Introduction: Distal tibial fractures are common long bone fractures that occur mainly due to a high velocity trauma. These are difficult to treat because of its subcutaneous location and poor blood supply. Many studies have been published on modalities of treatment of distal tibia fractures. Available options are Intramedullary nails, locking plates and external fixators. The aim of our study was to compare intramedullary interlocking (IMIL) nailing and locking plate (LP) for the treatment of these fractures. Materials and methods: This is a prospective study consisting data of 20 patients with distal tibial fractures operated for IMIL nailing and LP. Patients were followed up for radiological and clinical outcome using The American Orthopaedic Foot and Ankle Society (AOFAS) score. Results: The functional outcome was assessed by AOFAS score. Overall 10 patients obtained an excellent result (50%) and 8 obtained a good result (40%) and 2 obtained fair result (10%). IMIL nailing shows lower rate of delayed wound healing and superficial infection and plating may avoid malunion and knee pain. Discussion: The study suggests superiority of IMIL nailing over LP in terms of less rates of infections, early rate of union, early weight bearing. Whereas LP is better in anatomical and fixed reductions of the fracture and less knee pain. Hence the modality of treatment should be based on the patient’s injury pattern, surgeon’s expertise and clinical condition.
