Closed reduction of the traumatic posterior-dislocation of hip joint using a novel sitting technique: A case series.

RATIONALE: Traumatic hip dislocation is a common joint dislocation. Delayed reduction has been shown to increase the risk of avascular necrosis of the femoral head. Most of the traditional methods must be performed under general anesthesia or spinal anesthesia to relax hip muscles. Anesthesia will prolong the interval between the injury and the reduction.

PATIENT CONCERNS: 16 patients presented with hip pain and a leg shortened, flexed, internally rotated and adducted.

DIAGNOSES: X-ray and CT-scan showed acute closed posterior dislocation of hip.

INTERVENTIONS: Closed reduction of the traumatic posterior-dislocation of hip joint using a novel sitting technique.

OUTCOMES: Among these 16 patients, 15 hips were successfully reduced using the Sitting Technique (table 1), indicating the success rate was 93.8%(15/16). A total of 12 patients were followed up, with a mean period of 23.5 months (range, 6-72 months). Among these 12 patients, 10 patients (83.3%) had excellent grade, 2 patients (16.7%) had good grade.

LESSONS: Sitting technique for treatment of traumatic posterior dislocation of hip joint does not need anaesthesia, which it shortens the interval between the injury and the reduction and saves valuable time for 6 hours of joint reduction. On the other hand, this method does no harm to the physicians' low back.
