  ABSTRACT: Hemiarthroplasty has been applied to treat proximal humeral fracture with variable outcomes. The purpose of this retrospective study was to assess factors affecting outcome in patients following hemiarthroplasty for proximal humeral fracture (PHF) repair. Patients with proximal humeral fractures treated over a 6-year period were included. Indications for hemiarthroplasty were severe three-part fractures associated with osteoporosis; four-part fractures with or without dislocation; splitting of the humeral head, or >45% collapse of the humeral head. Surgery outcome and postoperative complications were main outcome measures in this study. Thirty-three of 47 patients were included in the final analysis (mean age 64.3 years, range 43-82). Mean postoperative follow-up was 44.4 (range 36-57) months. Postoperative complications (shoulder dislocation, mild shoulder subluxation, heterotopic ossification) occurred in seven patients. Healing of the greater and lesser tubercles was abnormal or poor in 18 patients. These patients had significantly higher pain scores (4.0 ± 1.1 vs. 2.2 ± 1.1) and significantly lower capacities for active lifting (79.3 ± 9.6 vs. 121.7 ± 24.3), external rotation (20.7 ± 3.7 vs. 39.2 ± 10.3), and Neer scores (79.2 ± 5.7 vs. 90.6 ± 3.6) versus patients who exhibited complete healing (all P < 0.001). Patient age, type of surgical approach, and fracture type were not major influencers of outcome. In conclusion, the healing of the greater and lesser tubercles is the major determinant of outcome following hemiarthroplasty for PHF repair.

  ABSTRACT: To summarize our surgical experience of release and balance of soft tissues around the hip in total hip arthroplasty (THA) for patients with adult dysplasia of the hip (ADH). From January 2001 to January 2006, 29 adult patients with dysplastic hips (31 hips) were included in this study. Among them, there were 19 women and 10 men, aged from 38 to 65 years. According to the Crowe classification system, there were 8 type I, 12 type II, 6 type III and 5 type IV. THA was performed via a lateral approach. All acetabular cups were reconstructed at the original anatomic location through soft tissue releasing around the hip to restore limb length, and techniques of balance of soft tissue were applied to extend the strength of the hip abductor and improve its function. All patients had restoration of limb length (range, 1.5-4.5 cm). One postoperative dislocation occurred due to slight enlargement of the angle of abduction of the acetabulum. At 1.5-year follow-up (mean, 3.2 years) in 29 patients, the Harris score had increased from 42.6 preoperatively to 85.4. All hips were pain free with good function. In order to restore the anatomic structure and physiologic function of the affected hip, the technique of release and balance of soft tissues around the hip should be applied cautiously in arthroplasty of ADH.

  ABSTRACT: To summarize the surgical experience of release and balance of soft tissues around hip in total hip arthroplasty for patients with severe hip dysplasia. From January 2001 to January 2006, 29 patients (31 hips) of adult dysplasia of hip were included in the study. Among them, there were 22 females and 7 males, age from 38 to 65 years with average of 53 years. According to Crowe classification system, there were 22 in type III, 9 in type IV, and Harris score was 42.6 preoperatively. Total hip arthroplasty was performed via lateral approach. All the acetabular cups were reconstructed at the original anatomic location through release of soft tissue around hip to restore limb length, and techniques of balance of soft tissue were applied to extend force arm of hip abductor and improve its function. All the patients had restoration of limb length (ranged from 2.5 cm to 4.5 cm). One case of postoperative dislocation was occurred due to slight large of acetabular obtuse angle. Follow-up for 1-5 years (average 3.2 years) in 29 patients, the Harris score increased to 85.4 postoperatively. All hips had released from pain and functioned well. In order to restoration anatomic structure and physiologic function of affected hip, the technique of release and balance of soft tissues around hip should be applied and cautioned in arthroplasty of dysplastic hip.
