Aim: To analyse the functional outcome of Ankle joint after medial malleolar fracture treated with ORIF with TBW and CC Screws.

Materials and Method: This is prospective study done in Calcutta national medical college and hospital, Kolkata from September 2019 to August 2020. In this study 20 cases of Medial malleolar ankle fracture were analysed. Muller Classification used. Road traffic accident, Twisting injury and fall from height are major mode of injury. TBW & 4.0 mm Cannulated Cancellous screw were used for fixation. Out of 20 cases 10 cases treated by TBW & 10 cases treated by 4mm CC screw.

Results: According to Baird and Jackson scoring system out of the 20 patients treated, Excellent and good functional results were achieved in 90% in TBW patients and in 80% in CCS patients with A better range-of-motion (especially for dorsiflexion of ankle) was noticed in TBW group. Radiological union took place in TBW patients (mean time 18 weeks) earlier than in CCS patients (mean time 20 weeks). On comparing the results in both groups, better results were seen in TBW group as compared to CCS group.

Conclusion: In this study we observed that the functional outcome of Ankle joint after medial malleolus fracture treated with open reduction and internal fixation with tension band wiring gives better results in range of motion and union more stable as compared to open reduction and internal fixation with 4.0 mm Cannulated Cancellous screws.
