Radiological Outcome of Fracture of Neck-of-Femur Treated with Two versus Three Cannulated Screws Fixation in Adults.

Abstract

To compare the radiological outcome of two cannulated screws versus three cannulated screws in fixation of fractures of neck-of-femur in adults. An experimental study. Department of Orthopedic Surgery and Traumatology, Mayo Hospital, Lahore from September 2013 to September 2015. A total of one hundred and twenty adults, age ranging from 14-49 years, with all Garden's types fracture of neck-of-femur, were inducted through Accident and Emergency Department after a written informed consent. Patients were randomly divided into two treatment groups. Group A underwent two cannulated screws fixation, while Group B underwent three cannulated screws fixation. Radiological union was checked at the 12th postoperative week. The median age was 36 years with interquartile range of 1.5 (p=0.895). There were 54 (90%) males and 06 (10%) females in GroupA; while 55 (91.7%) males and 05 (8.3%) females in Group-B (p=0.752). In the 12th postoperative week, radiological union was evident in 107 (89.2%) patients. The frequency of radiological union at 12th postoperative week was 98.3% in Group A and 80.0% in Group B (p<0.001). Frequency of radiological union of two cannulated screws fixation was found to be significantly higher than three cannulated screws fixation in adults with fracture of neck-of-femur.
