Treatment Outcome of Sub-Trochanteric Fractures of Femur Fixed with Dynamic Condylar Screw
Keywords:Dynamic Condylar Screw, Radiological Union, Implant Failure, Case Series
Objective: To find out clinical and radiological union, implant failure and mobility at adjacent hip joint for sub-trochanteric fracture treated with dynamic condylar screw fixation.
Method: This case series was conducted in the Department of Orthopedics Surgery and Traumatology Unit I (DOST-I), Mayo Hospital, Lahore from January 2013 to January 2015. A total of 26 patients with closed subtrochanteric fracture fixed with dynamic condylar screw were assessed radiologically between 20 to 60 years
of age after acute trauma within two weeks. We followed all patients at two weeks' interval for 1st month and after one month till nine months post-operatively at four weeks interval. We assessed all patients till last follow up for radiological union, implant failure and range of motion of hip joint using Modified Harris Hip
Results: Out of 26 patients, 18 (69.23%) were males and 08 (30.8%) were females. Median age was 37.5-year and inter-quartile range was 16.50. At the end of the study, were 25 (96.15%) fracture united but 01 (3.85%) developed non-union. These non-union was associated with implant failure. The implant failure was
observed between 3rd to 5th months.
Conclusion: We concluded that fixation of sub-trochanteric fractures of femur with dynamic condylar screw can be treated efficiently in terms of fracture union.
