OBJECTIVE: The purpose of this study was to evaluate the results of dynamic condylar screw
system in the management of subtrochanteric femoral fractures, regarding union time, implant
failure rate; infection rate and functional out come.
STUDY DESIGN: A prospective case series.
PLACE AND DURATION OF STUDY: This study was carried at the department of Orthopedic
Surgery and Traumatology Liaquat university of Medical and Health, sciences Jamshoro, during
January 2008 to December 2009.
MATERIAL AND METHODS: Total 52 consecutive patients with subtrochanteric fracture were
studied .Four patients were lost during follow–up and total 48 patients were finally assessed.
The inclusion criteria was closed subtrochanteric fractures in adults of both gender aged 20
years or above; pathological fractures and open fractures were excluded from the study. After
fixation of fractures with dynamic condylar screw system patients were followed -up for 6-12
months, the mean follow up period was 8 months. Results of treatment were assessed by the
RESULTS: Among 48 studied cases, males were 29(60.42%) and female 19(39.58%). Most common
mode of injury was road traffic accidents in 32 patients (66.66%) and 16 patients had fall.
All the patients underwent operative treatment by fixation of DCS. Autogenous bone graft was
done in 07 patients. The union rate in this series was (93.5%). Implant failure was observed in
03(6.25%) patients, 03 (6.25%) patients developed varus deformity and infection occurred in 02
(4.66 %). According to criteria of Radford, we achieved good to excellent results in 81 % cases,
fair in 6 (12.5 %) patients, poor in 03(6.25%0) patients.
CONCLUSION: We conclude that subtrochanteric fractures need open reduction and internal
fixation to avoid complications like implant failure, nonunion, infection, and mal-union. In our
circumstances we achieve good results by the use of dynamic condylar screw.
