Operative treatment of acetabular fractures through the extensile Henry approach.
OBJECTIVE
The purpose of this study was to evaluate the previously unreported application of the extensile Henry approach to the operative treatment of acetabular fractures.


METHODS
Thirty-one cases were retrospectively reviewed at an average follow-up of 18.5 months.


RESULTS
There were 8 simple and 23 complex associated fracture patterns. The average operative time was 4.5 hours, and the average blood loss was 1,160 mL. Reduction was anatomic in 26 patients (84%), satisfactory in 4 patients (13%), and unsatisfactory in 1 patient (3%). Radiographic results at follow-up were 25 excellent results, 4 good results, and 2 poor results. Twenty-six patients reported no limitation of ordinary activities, whereas five patients had to modify their activities because of pain. No heterotopic ossification occurred in 24 patients (77%). In the seven patients with heterotopic ossification, only one patient had a significant decrease in hip range of motion. Additional complications were two cases of superficial wound infection, one case of hardware failure, and two cases of avascular necrosis of the femoral head. There were no iatrogenic injuries to the sciatic nerve, nor was there any development of flap necrosis.


CONCLUSIONS
The extensile Henry approach is a versatile approach offering an excellent exposure for surgical treatment of acetabular fractures. The rate of complications is comparable with or lower than that of other surgical approaches. By providing a direct exposure of the posterior pelvis, the extensile Henry approach has the advantage of minimizing the risk of iatrogenic injury to the sciatic nerve. In addition, the incidence of clinically significant heterotopic ossification may be reduced through the use of low-dose radiation prophylaxis.
