The aims of spinal deformity surgery are to achieve balance, relieve pain and prevent recurrence or worsening of the deformity.The main types of osteotomies are the Smith-Petersen osteotomy (SPO), pedicle subtraction osteotomy (PSO), bone-disc-bone osteotomy (BDBO) and vertebral column resection (VCR), in order of increasing complexity.SPO is a posterior column osteotomy in which the posterior ...

An opening-wedge osteotomy is well recognised for the management of limb deformity and requires an understanding of the principles of geometry. Translation at the osteotomy is needed when the osteotomy is performed away from the centre of rotation of angulation (CORA), but the amount of translation varies with the distance from the CORA. This translation enables proximal and distal axes on eith...

Hallux abductovalgus is one of the most common deformities addressed by foot and ankle surgeons. Surgically, it can be approached using a wide variety of procedures. After performing the first metatarsal osteotomy, the final step is often to realign the great toe in a rectus position. This is performed with an osteotomy of the proximal phalanx. The Akin osteotomy is a medially based closing wed...

The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis. The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighteen were selected and revi...

Condylar hyperplasia is a well-known pathologic entity with an established treatment protocol. Traditionally, saws and drills have been used in the condylar osteotomy. The use of ultrasonic systems has optimized many procedures in the maxillofacial area; however, exploration of the use of this technique for condylectomy has been limited. Ultrasonic systems offer several advantages, such as a de...

Background: Nowadays combined high tibial osteotomy and ACL reconstruction is accepted as a safe and effectivesurgery for patients with symptomatic varus osteoarthritis and anterior knee instability; however, the source of varusdeformity is sometimes the femoral bone. No studies have reported concomitant ACL reconstruction and distal femoralosteotomy in ACL-deficient knees wit...

Background:   Hallux valgus deformity is a common chronic problem in middle age and elderly. Different surgical procedures have been introduced so far with their proposed indications for each. This study aimed to compare three   current procedures namely Chevron osteotomy, Scarf osteotomy and McBride technique.     Methods:   In this study, 44 patients were included from 2010 to 2013. All patie...

Mandibular access osteotomy allows mobilization of craniofacial skeleton and replacements of bony fragments either pedicled on their soft tissues or as free bone segments. This provides increased and direct exposure of posterior region and surrounding vital structures and avoid the need to resect uninvolved structures. Roux in 1836 suggested the division of the lower lip and mandible for improv...

BACKGROUND Clinical and radiological outcomes including fixation stability of osteotomy site were compared in rheumatoid arthritis (RA) patients who underwent modified Ludloff osteotomy to correct hallux valgus with osteotomy site fixation using two screws versus those who underwent additional fixation using a plate. METHODS The fixation technique performed with two screws was used to fix the...
