Background Clinical studies have shown that many patients may have abnormally reduced myocardial shortening despite preserved ejection fraction (EF). Mathematical modeling explains this apparent paradox by demonstrating, that whilst myocardial shortening determines radial strain (RS), it is absolute wall thickness (AWT) rather than RS that determines EF. We sought in vivo cardiac MR (CMR) evide...

STUDY DESIGN: A description of pedicle subtraction osteotomy for correction of kyphotic deformity of the cervical-thoracic spine and a prospective evaluation of the surgical outcomes. OBJECTIVES: To describe the surgical technique and the postoperative results of pedicle subtraction osteotomy in the upper thoracic spine and the cervical-thoracic junction. SUMMARY OF BACKGROUND DATA: Pedicle sub...

BACKGROUND Radius osteotomies showed favorable clinical outcome in Kienböck's disease. However, few articles have been published on the long-term outcome of lateral wedge osteotomy of the radius in patients with advanced stage Kienböck's disease. METHODS Eleven patients with Lichtman stage IIIB/IV Kienböck's disease (group A; mean follow-up period, 86.1 months; range, 48 to 163 months) and 14...

Types of equinus, surgical management for equinus involving the Ytalocalcaneal osteotomy supplementing an external fixation device is presented. A case report is introduced involving surgical correction of a 53 year-old male who had a severe equinus flat top talus with mild varus secondary to clubfoot surgery. Treatment included surgical correction utilizing Steindler stripping, Achilles tendon...

Upper femoral osteotomy is a recognised treatment for selected patients with Perthes' disease. The results of this procedure were investigated at skeletal maturity in 44 patients (48 hips). The indication for operation was Catterall group II, III, and IV hips with 'head-at-risk' signs. Harris and Iowa scores were calculated clinically, and each hip was assigned radiographically to one of the fi...

Aponeuroses are sheet-like elastic tendon structures that cover a portion of the muscle belly and act as insertion sites for muscle fibers while free tendons connect muscles to bones. During shortening contractions, free tendons are loaded in tension and lengthen due to the force acting longitudinally along the muscle׳s line of action. In contrast, aponeuroses increase in length and width, sugg...

PURPOSE To compare one-stage combined surgery with and without preoperative traction, in older children with developmental dislocation of the hip (DDH). METHODS Records of 9 children who underwent combined surgery for DDH with preoperative traction in 12 hips (group 1) and 12 undergoing the same procedure without preoperative traction in 16 hips (group 2) were retrospectively reviewed. The su...
