Intramedullary Interlocking Nail in Distal One Third Tibia Fracture: A Retrospective Study in Tertiary Care Center

Abstract

AIM: To assess functional outcome of intramedullary interlocking nail in distal tibia fracture where distal locking screw is applied after inserting proximal locking screw.

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 fibula fracture are included in the study. Intrarticular fracture, GAIIIb and lost follow up cases were excluded from the study. Proximal interlocking screws are placed at first 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%).
