| description | Bacground/Aim. Intertrochanteric fractures of the femur are the third most
common fractures among all bone fractures. Today in everyday orthopedic
practice a number of different methods of treatment of trochanteric fractures
of the femur are applied. Despite the improvement in the development of new
implants, the percentage of serious complications of the treatment of these
fractures remains very high, varying from 10% to 20%. One of the most serious
complications of internal fixation of intertrochanteric fractures is nonunion
of fractures due to the lack of additional axial dynamisation of implants.
The aim of this study was to determine the efficacy of double dynamisation in
stable and unstable intertrochanteric fractures treatment using the self
dynamisable internal fixator. Methods. During the period from 2000 to 2009 we
analyzed the use of selfdynamisable internal fixator (SIF implant) in the
treatment of 247 patients with stable and unstable intertrochanteric
fractures. Fracture types were classified according to the AO Fracture
Classification/Orthopaedic Trauma Association Scheme. Salvati and Wilson
scoring systems were used for functional assessment considering pain, walking
ability and hip movements of operated patients. Results. Of the total number
of treated patients, 134 were males and 113 females, aged 19 to 90 (average
49.6) years. More than a half of the patients were older than 50 years.
Monitoring of the patients after the operation was carried out clinically and
radiographically for a period of three to six months in all the patients,
whereas a 2-year follow-up was conducted in 176 (71.2%) patients. The average
duration of surgery was 47 min, the average blood loss 145 mL, and the
average fluoroscopy time was 16 sec (8-97 sec). The average time for union
was 3.7 months (3-6.5 months). Double dynamisation (dynamisation along the
neck and shaft of the femur) was observed in 85 (34.4%) patients, and was on
average 4.3 mm (1.5-8 mm). All fractures managed with dynamisation implants
healed completely within no later than six months after the surgery. In 17
cases there was a cut-out phenomenon of implant, while in seven cases there
was mechanical implant failure. Complications were detected within 3 to 6
weeks after the surgery, and treated by the method of intramedullary
fixation. During the study, there were no cases of infecton and
thromboembolic complications detected. Conclusion. The concept of double
dynamisation improves the fracture healing in the stable and unstable
intertrochanteric fractures using the selfdynamisable internal fixator. This
biological method of fixation provides healing of intertrochanteric fracture
in the optimum period of time, significantly reducing the risk for mechanical
failure. |
