Revision of Failed Open Reduction of Developmental Dysplasia of the Hip.

Background: The most common causes of re-dislocation after open reduction are inadequate exposure and failure to release the obstructing soft tissues inside and around the hip.

Methods: This clinical study included 33 consecutive children (34 hips) who underwent a revision surgery after failed open reduction of developmental dysplasia of the hip (DDH).

Results: According to the McKay clinical criteria, the results were good in 28 cases (82.

A comparative prospective study between stemmed versus an unstemmed tibial component in total knee arthroplasty in obese patients.

Background: There is no consensus in the literature regarding the patients with obesity who do well with TKA, or this group is at risk of a variety of complications. Implant choices between the two types of implants which either long or standard stem can improve the likelihood that a patient with obesity will achieve high scores for function and quality of life after TKA.

Methods: This prospective clinical study included 200 patients who were categorized into two groups: group (1) traditional (standard) unstemmed cemented tibial tray (n = 100 patients) and group (2) stemmed cemented tibial tray with the cementless press-fit stem (n = 100 patients).

Sprengel's deformity of the shoulder joint treated by Woodward operation.

Background: Sprengel's shoulder deformity is a rare condition that happens because of the abnormal termination of the caudal migration of the scapula during the embryonic period.

Methods: This retrospective clinical study included 10 consecutive children who underwent a Woodward operation to correct the Sprengel's shoulder deformity.

Results: The average preoperative Cavendish grade for cosmetic evaluation was 3.

Pigmented villonodular synovitis managed by total synovectomy and cementless total hip arthroplasty.

Background: Pigmented villonodular synovitis or PVNS is a benign proliferating disease of the synovium; it behaves much as a neoplastic process does.

Methods: This retrospective clinical study included 11 consecutive cases who underwent for total synovectomy combined with cementless total hip arthroplasty of PVNS of the hip joint.

Results: The mean patient preoperative hip score of Harris was 46.

Short follow-up evaluation of proximal femoral varus osteotomy for treatment of Legg-Calvé-Perthes disease.

Background: There are many methods of treating Legg-Calvé-Perthes disease, including operative and nonoperative methods. Femoral varus osteotomy is one of the surgical methods used to treat this disease, and it involves changing the alignment of the proximal femur to improve containment of the femoral epiphysis in the acetabulum. The aims of this study were to evaluate the results of femoral varus osteotomy for the treatment of Perthes disease according to various classification and grading schemes, as well as to compare the results to those obtained using other methods of treatment reported in the literature.

Evaluation of functional outcomes and preliminary results in a case series of 15 children treated with arthroscopic release for internal rotation contracture of the shoulder joint after Erb's palsy.

Introduction: The purpose of this study was to evaluate shoulder function following minimally invasive subtotal subscapularis muscle and periarticular capsuloligamentous arthroscopic release in children with Erb's palsy.

Methods: A prospective study was conducted on 15 consecutive children who underwent subtotal subscapularis muscle and periarticular capsuloligamentous arthroscopic release to treat internal rotation contracture of the shoulder joint after Erb's palsy. Age at surgery ranged from 24 to 38 months (average 28.

Fixation of Intertrochanteric Valgus Osteotomy with T Plate in Treatment of Developmental Coxa Vara.

Background: Although the valgus subtrochanteric osteotomy is considered as a standard surgical treatment for coxa vara, there is no consensus on the optimal method of fixation and osteotomy technique. Fixation of the osteotomy has been achieved by various methods including external fixation and internal fixation with pins and cerclage and a variety of plates. The aim of this study is the evaluation of the results of developmental coxa treated by Y intertrochanteric valgus osteotomy fixed with a T-buttress plate compared with other methods of fixation in the literature.

Neglected posterior dislocation of the elbow.

The study included two adults and four children who underwent open reduction for subacute, untreated posterior dislocation of the elbow. Elbow stiffness was the main indication for surgery, and in all cases elbow movement was inadequate for the activities of daily living. Mean time from injury was 2 months and mean follow-up was 19 months.
