BACKGROUND Distal osteotomies of the first metatarsal are commonly used to correct hallux valgus deformities. Of the distal osteotomies, the Austin osteotomy is popular among foot surgeons on an international level. The precision of the osteotomy is important to achieve a congruous osteotomy. OBJECTIVES The purpose of this study was to examine the effects of experience and technique on creati...

OBJECTIVES To evaluate the influence of the type of osteotomy in the inferior aspect of the mandible on the mechanical performance. MATERIALS AND METHODS The study was performed on 20 polyurethane hemimandibles. A sagittal split ramus osteotomy (SSRO) was designed in 10 hemimandibles (group 1) with a vertical osteotomy in the buccal side (second molar level) and final osteotomy was performed ...

Once used routinely, trochanteric osteotomy in total hip arthroplasty now is usually limited to difficult primary and revision cases. There are three types: the standard trochanteric osteotomy and its variations, the trochanteric slide, and the extended trochanteric osteotomy. Each has unique indications, fixation techniques, and complications. Primary total hip arthroplasty procedures requirin...

Pemberton's osteotomy has been recognized as a standard technique for the treatment of acetabular dysplasia. The aim of this article is to describe the surgical technique of a double-level pelvic osteotomy. To the authors' knowledge, this technique has never been reported. The osteotomy was performed in a case of severe pan-acetabular dysplasia where a single, classic Pemberton's osteotomy was ...

PURPOSE The purpose of this study was to objectively evaluate hypoesthesia of the upper lip following Le Fort I osteotomy in combination with mandibular osteotomy with trigeminal somatosensory evoked potential (TSEP). SUBJECTS AND METHODS The subjects consisted of 25 patients with mandibular prognathism with maxillary retrognathism mandibular prognathism with or without asymmetry, who underwe...

BACKGROUND There are several posterior decompression techniques for lumbar spinal stenosis (LSS). There is a trend towards performing less invasive surgical procedures, but no multicentre randomized controlled trials have evaluated the relative efficacy of these techniques at short and long-term. METHOD/DESIGN A multicentre randomized controlled trial [the Spinal Stenosis Trial (SST) (part of...

BACKGROUND To compare radiologic results of posterior release, internal distraction, and final pedicle subtraction osteotomy (PSO) and spinal fusionwith one-stage posterior vertebral column resection (PVCR) in treating multi-level severe congenital scoliosis. METHODS Forty-onesevere congenital scoliosis patients were used in the study. Group A comprised 24 patients who underwent one-stage PVC...

Triple pelvic osteotomy is an accepted technique to correct acetabular dysplasia and degenerative labral pathology in young adults. Few papers mentioned the rate of nonunion at site of osteotomy of pubic bone and ischeal bone. No report about nonunion at site of osteotomy of iliac bone (up to the author's knowledge). Here the author reported a case of triple pelvic osteotomy which is complicate...

Greater understanding of the surgeon's task and skills are required to improve surgical technique and the effectiveness of training. Currently, neither the objective measurement of osteotomy forces during endoscopic sinus surgery (ESS) nor the validity of the properties of cadaver materials, are well documented. Measurement was performed of peak axial osteotomy force during ESS. A comparison wa...

INTRODUCTION Insufficient femoral head coverage is found in a variety of diseases, with acetabular dysplasia as the most frequent disorder and triple pelvic osteotomy as the most recently introduced surgical treatment. OBJECTIVE This study analyses pre- and postoperative pathoanatomic characteristics of triple in comparison to Salter and Chiari osteotomies, with a logistic regression analysis...
