Arthroscopy for diagnosis and treatment of acute posterior dislocation of the hip / 中华创伤杂志

ABSTRACT

Objective To evaluate the significance of arthroscopy in diagnosis and treatment of acute posterior dislocation of the hip. Methods From August 2005 to April 2009, 32 patients with acute posterior hip dislocation underwent hip arthroscopy in our hospital. All patients were confirmed by symptoms, signs, X-ray examination and CT scan. There were 26 males and 6 females, at mean age of 38.5 years (range 23-55 years). An arthroscope was introduced to evaluate the intraarticular lesions routinely. Then, arthroscopic debridement was performed. Eight patients with acetabular fractures were treated by open reduction and internal fixation after arthroscopy. The Sanders scores were employed to evaluate the postoperative hip functions. Results Among 32 patients, there were 29 patients with loose bodies, three with tear of the ligamentum, 12 with labrum injuries and eight with acetabulum fractures that required a second stage open reduction and internal fixation. There were no complications of vessel or nerve injuries peri- or post-operatively. An average period of follow-up for 10 months (range, 5-24months) were available for all patients, which showed excellent results in 23 patients, good in five and fair in four according to the Sanders scores. Conclusion Hip intraarticular lesions can be evaluated and confirmed by the arthroscope, under which the loose bodies, tear of the ligamentum teres and labrum injuries can be cleared effectively.
