INTRODUCTION: One hundred and eight patients with varus gonarthrosis were treated with high tibial osteotomy (HTO) in 2001. Fifty one patients received an open wedge osteotomy by using the 'Puddu' plate and 57 patients received a Coventry-type closing wedge osteotomy. For both groups the follow-up examination period was 22.5 months ...

One of the criticisms of the percutaneous lateral nasal osteotomy technique is the potential for unfavorable, visible scarring. No clinical study has compared the external percutaneous approach with an internal approach to evaluate scarring in the same patient. This prospective, randomized, blinded study was designed to test the hypothesis that ...

Pelvic support osteotomies for chronically dislocated hips improve stability but result in limb-length discrepancy and valgus deformity of the knee. We prospectively evaluated and followed up 16 patients (14 females, two males) to ascertain whether a monolateral external fixator could achieve a pelvic support osteotomy and eliminate the limb-length discrepancy ...

Metatarsal osteotomies were done in 21 feet in 14 patients (11 females, ...

We reviewed 34 knees in 24 children after a double-elevating osteotomy for late-presenting infantile Blount's disease. The mean age of patients was 9.1 years (7 to 13.5). All knees were in Langenskiöld stages IV to VI. The operative technique corrected the depression of the medial joint line by an elevating ...

Periacetabular osteotomies, such as rotational acetabular osteotomy (RAO) for osteoarthritis (OA) secondary to hip dysplasia, have produced satisfactory medium- and long-term results in early OA. However, as the degree of surgical invasion of these procedures is comparatively major and long-term postoperative rehabilitation is required, this procedure is generally not indicated ...

Between January 1996 and December 1999, we performed 30 derotational osteotomies with compression nailing in 29 patients. In 18 cases (group 1), we used an intramedullary saw (minimally invasive technique), and in 12 cases (group 2), we used a conventional open technique. Follow-up included clinical, conventional radiological, and computer tomographical ...

The Bernese periacetabular osteotomy has a considerable rate of postoperative complications such as reflex sympathetic dystrophy, motor nerve palsy, heterotopic ossification, and delayed union of the ilium, which are assumed to be caused by extensive exposure or asphericity of the osteotomy surfaces. To address these issues, we developed the curved ...

BACKGROUND: While rotational acetabular osteotomy has been reported to be successful for the treatment of osteoarthritis of the dysplastic hip, little is known about its efficacy in the treatment of osteonecrosis of the femoral head.

We report the results of long-term follow-up after Vickers' physiolysis of the trapezoidal delta phalanx in a boy aged five year and six months with bilateral clinodactyly of the little finger. Radial deviation of the little finger was corrected from 36 degrees to 15 degrees on the left, and from ...

BACKGROUND: Tibial osteotomy is a treatment for younger and/or physically active patients suffering from uni-compartmental knee osteoarthritis. The open wedge osteotomy by the hemicallotasis technique includes the use of external fixation. The use of external fixation has several advantages, as early mobilization and the opportunity for optimal correction. However, the ...

Ulnar shortening is well accepted in the treatment of ulnar abutment but less so in patients with a shortened radius and ulnar-sided wrist pain as a result of a Colles fracture. Sixteen patients with pain and reduced range of movement (ROM) and a median preoperative ulnar positive variance of 5 ...

The optimum surgical treatment of patients with Perthes' disease has not been decided. We compared the clinical and radiographic results at skeletal maturity of the femoral varus osteotomy and the Salter innominate osteotomy for treatment of patients with Perthes' disease. Treatment in 46 patients was by femoral varus osteotomy and ...

The surgical options for hallux rigidus in the presence of painful but moderate degenerative metatarsophalangeal joint disease are limited to either joint-destructive or joint-preserving procedures. The following study compared the effectiveness of 2 joint-preservation procedures. Forty-nine patients, with a mean age of 53 years, underwent phalangeal osteotomy and were reviewed ...

Intertrochanteric osteotomy may postpone the need for total hip replacement (THR). In young patients with an acquired deformity of the femoral head and secondary osteoarthritis, a valgus intertrochanteric osteotomy may allow better congruency but the acetabular cover may become insufficient because of subluxation of the femoral head. In patients with ...
