We have compared different types of intertrochanteric osteotomy for avascular necrosis of the hip and evaluated their performance in the light of improving outcome after total hip arthroplasty (THA). During a period of 14 years we performed 63 flexion osteotomies (partly combined with varus or valgus displacement), 29 rotational osteotomies, 13 varus osteotomies, eight medialising osteotomies a...

Pedicle screw instrumentation constructs have become a cornerstone in the treatment of adult spinal deformity and instability. They are known to provide greater rigidity and enhanced ability to correct and maintain spinal alignment. Biomechanical data, however, demonstrate that increased construct stiffness is associated with increased loading within adjacent segments [1– 9]. Increasingly stiff...

background: high tibia osteotomy (hto) is a common surgical operation for correction of genu varum deformity. in some patients,there are concurrent tibia vara and genu varum (bow leg). this study aimed to consider the possibility of better correction of bow leg deformity after double level tibial osteotomy (dlto). materials and methods: a case series of 10 patients of genu varum in addition to ...

introduction : lateral osteotomy is a major part of rhinoplasty for remodeling external facet of the nose and narrowing of nasal base and dorsum after removal of the hump with the edema and ecchymosis being the major sequels of the operation. the present study compared post-operative edema and ecchymosis and mucosa tears between internal and external osteotomy techniques. materials and methods ...

Aim The aim of this report is to present a brief review of the current literature on the management of EEC. Case Report A term male neonate presented at birth with classic bladder exstrophy, a variant of the exstrophy-epispadias complex (EEC). The defect was covered with sterile silicon gauzes and waterproof dressing; at 72 hours of life, primary closure without osteotomy of bladder, pelvis, an...

BACKGROUND Currently, there are many reports about congenital scoliosis (CS) treatment, but there are still controversies existing with respect to selecting its surgical methods. METHODS Retrospective analyses were conducted on 31 CS patients. The surgical treatments included the following: posterior instrumentation (10 patients; group 1), pedicle subtraction osteotomy (11 patients; group 2) ...

Introduction: This study is designed to explore the biomechanical principles of posterior bilateral pedicle screw on steps progressively and tight closure on every step for severe angular kyphosis and the indication conditions and clinical pathways of above new technique. Materials and Methods: A total of 90 patients have severe angular kyphosis, 37 males and 53 females, with an average age of ...

Ankylosing spondylitis patient with chin-on-chest deformity and Anderson lesion as the apex of kyphosis in the cervicothoracic region is rare, and there was no consensus on the best surgical strategy for it. Here we report such a rare case of a 28-year-old man, who presented with a history of unsatisfactory appearance, cervicothoracic kyphosis, neck pain (VAS = 7), difficulty in ambulation, and...

Femoral head coverage achieved with an acetabular osteotomy for hip dysplasia is achieved by acetabular rotation that can be restricted by osteotomy orientation and soft tissue attachments to the acetabular fragment. Procedures that allow excess rotation or motion in an undesirable direction (especially external rotation) may have undesirable consequences. Rotational aspects of these procedures...
