RESUMEN
Objectives: To determent the effectiveness of Rikli and Regazzoni three-column theory in treating intra-articular fractures of the distal radius with T-plate and K-wire in terms of functional outcome and fracture union. METHODS: The cross-sectional study was conducted at the Department of Orthopaedic Surgery and Traumatology, King Edward University, Mayo Hospital, Lahore, Pakistan, from June 2013 to March 2017, and comprised patients aged 15-60 years having closed intraarticular fracture of the distal radius <1 month older. The subjects were divided into two group A, managed by percutaneous K-wire fixation, and group B, managed with open reduction and internal fixation using T-plates. Wound infection, supination and pronation, flexion and extension at the wrist joint, bone union and functionality were observed. All patients were followed up with intervals for 12 months in the out-patient department, and wound infection and supination and pronation of the forearm were observed clinically. Union was observed using the standard criterion, and function was evaluated using the Disabilities of Arm, Shoulder and Hand score. Data was analysed using SPSS 20. RESULTS: Of the 60 patients, there were 30(50%) with mean age 48.83±11.11 years in group A, and 30(50%) with mean age 49.87±13.45 years in group B. Overall, there were 49(81.7%) males and 11(18.3%) females. There were 33(55%) cases with right side involvement, and 27(45%) had the left side involved. Functionality imprived significantly in both groups (p<0.05). Union was observed in all cases in both groups, while the mean duration in group A was 9.21±1.74 weeks, and in group B it was 9.87±2.14 weeks. Conclusion: Restoration of the three columns of distal radius could either be fixed with T-plates and K-wires because there was no significant difference between the two groups.
