Objective: To compare the partially threaded versus fully threaded cannulated screw fixation methods in stable neck of femur fracture in terms of early functional outcomes in patients of age 60 and above.
Methods: A randomized controlled trial was conducted at Orthopedic Unit-II, Mayo Hospital Lahore, Pakistan from July 2021 to July 2022. A total of 82 (41 in each group) patients of both genders, aged 60 or above were included. All patients had garden Type-I or II and were mobile before they fractured the femoral neck were included. In Group-A, cannulated screw fixation (cancellous screws 6 mm) was done using partially threaded screws while fully threaded screws (cancellous screws 6 mm) were used in Group-B. Patients were followed up at six weeks, three months and six months interval for "Radiographic Union Scale for Hip (RUSH)" and "Harris Hip score".
Results: In a total of 82 (41 in each group) patients, 66 (80.5%) we male. At 6 ^th week (p=0540) and 3 ^rd month (p=0.653) postoperatively, no significant differences were seen between groups for Hip Harris score. However, at 6 ^th month, functional outcome of Group-B patients was significantly better as compared to Group-A (p=0.038). Mean RUSH score in Group-A and in Group-B at 6 ^th month postoperative was 25.45±2.73 and 30.52±2.39 (p<0.001).
Conclusion: Fully threaded cannulated screw fixation is better in treating undisplaced neck of femur fracture as compared to partially threaded cannulated screw fixation in terms of early functional outcomes among the age group of 60 years and above. RCT Registration number: NCT05587660.
