Abstract

Objective: This study aims to determine the incidence of Deep Venous Thrombosis after hip fracture surgery by using Doppler Ultrasonography.


Study Design: Descriptive observational.


Setting: This study was conducted in the Orthopedics Department at Mardan Medical Complex, Mardan - Pakistan.


Materials and Methods: This study was performed on 50 consecutive patients of 40 years and above with proximal femur fractures (fracture of femoral head, femoral neck fracture and inter- trochanteric fractures) who were fulfilling the inclusion criteria. Informed consent was taken and operated on regular operation list. During the study period all the patients undergoing major orthopaedic surgery for Total Hip Replacement, Austin Moore Prosthesis, AO Screw fixation and Proximal femur fracture fixation by Dynamic Hip Screw and Interlocking Nail were investigated by Doppler ultrasonography by the same radiologist and were assessed for the occurrence of DVT. These patients were followed for 6 weeks post-operatively. The statistical significance of the results was analyzed using SPSS computer program.


Results: The total numbers of patients were 50 with average age of 62 years +/- SD. Male to female ratio was 1.2:1. THR was performed in 3 (6%) patients, AMP in 11 (22%) patients, DHS was performed in 28 (56%) patients, AO screw was performed in 6 (12%) patients and Interlocking Nail was performed in 2 (4%) patients. Overall incidence of DVT in the entire study group was 4% (2 of 50 patients). None of the patient received any form of thromboprophylaxis during the entire study period.


Conclusion: Our results suggest that incidence of DVT in Pakistani patients is low and is not comparable with American and European populations. Routine Thromboprophylaxis is perhaps not justified in every patient undergoing hip surgery. However, prophylaxis for patients with higher risk may be considered individually.
