are placed at frst followed by distal interlocking screw. Mechanism of injury, age, sex, union time, foot function index, secondary procedure, complications, deformities are analyzed in the study. RESULTS: All patients were retrospectively analyzed. We could not find any significant relation between post operative malalignment and better foot function index (p = 0.975). Early union may not improve overall foot function index (p = 0.202). Automobile accident is the commonest mode of injury (48.5%) followed by automobile pediastrian (39.4%). Postoperative malalignment consist of cornal (3%), saggital (3%) and shortening (3%). Infection is one of the commonest complication found in our study (6.1%).

The goal of the treatment is to provide stable fxation with minimal soft tissue injury. Various methods are involved in the treatment of this fracture Casting, nailing, plating, external fxator are well known methods of treatment. Plates can be inserted via open reduction internal fxation and minimally invasive technique. The open technique provides stability but requires extensive dissection. Minimally invasive plate technique may have a complication of hardware problem [1] . External fxator is associated with ankle stiffness [2] . Intramedullary nailing is one of the popular method of treatment of distal one third tibia fracture but it is not devoid of postoperative complication if not done properly [3] . It is technically demanding procedure and its role in the treatment of distal metaphyseal fractures has not been well defned [4] . It is difficult to reduce and hold fracture perfectly during free Rajiv Baral, Prakriti Raj Kandel, GP Singh, Kishor Man Shres- tha, Bipan Shrestha, Sagar Panthi, Department of Orthopedic, Universal College of Medical Sciences, Bhairahawa, Nepal Confict-of-interest statement: The author(s) declare(s) that there is no confict of interest regarding the publication of this paper.

PATIENTS AND METHOD: This is a retrospective study which was conducted in Universal college of medical sciences. This study was started one year back and last case was followed for one year. All thirty three cases with distal tibia extraarticular fracture 42A1 and 43A3, according to AO classification, within 7 cm from the ankle plafond of skeletally mature person presented in emergency along with Gustillo Anderson (GA) I, II, IIIa and fbula fracture are included in the study. Intrarticular fracture, GAIIIb and lost follow up cases were excluded from the study.
