Abstract Background Medial open-wedge high tibial osteotomy (HTO) is an effective and safe treatment method for medial osteoarthritis of the knee. However, unintended changes in posterior slope (PTS) may occur. Several factors cause PTS alterations after HTO; however, research on sagittal-plane inclination (SPOI) relation to sparse. The purpose this study was evaluate whether SPOI affects HTO. ...

To prevent patella infera in open wedge high tibial osteotomy, a new operation technique was developed. Instead of a proximal tibial tuberosity osteotomy, a distal osteotomy was performed and the tuberosity was fixed with one screw to the tibia. Initial experience in 17 patients was evaluated and compared with results of 20 patients with open wedge high tibial osteotomy with proximal tuberosity...

BACKGROUND Surgical orthopedic treatment of the mandible depends on the development of techniques resulting in adequate healing processes. In a new technical and conceptual alternative recently introduced by Puricelli, osteotomy is performed in a more distal region, next to the mental foramen. The method results in an increased area of bone contact, resulting in larger sliding rates among bone ...

The aim of this study was to establish the influence of the design of the sagittal split ramus osteotomy (SSRO) on stress distribution on the osteosynthesis in a photoelastic resin model. Two polyurethane hemimandibles were used to perform the osteotomies, tilted in the lateral sector of the first/second molar (group I) and the other descending downwards and laterally from the first molar (grou...

OBJECTIVES To assess the short term dental and skeletal stability of the anterior maxillary segment after segmental Le Fort I osteotomy with postoperative skeletal elastic fixation with or without occlusal splint. MATERIAL AND METHODS 29 consecutive patients underwent segmental Le Fort I osteotomy and elastic skeletal fixation was applied. Patients were divided into two groups according to wh...

background: legg-calve´-perthes disease is a juvenile idiopathic osteonecrosis in which the blood supply of femoral head is not sufficient and the bone dies provisionally. the aim of this study is to evaluate outcome of femoral osteotomy in children with lcpd in our university hospital.   methods: in a descriptive analytic study, between 2008 and 2013, patients with the diagnosis of legg-calve’...

PURPOSE To examine the separation of the pterygomaxillary region at the posterior nasal spine level after Le Fort I osteotomy in Class III patients. PATIENTS AND METHODS The study group consisted of 37 Japanese patients with mandibular prognathism and asymmetry, with maxillary retrognathism or asymmetry. A total of 74 sides were examined. Le Fort I osteotomy was performed without a pterygoid ...

The authors report the use of novel individualized surgical templates and titanium miniplates for Le Fort I osteotomy and evaluate the accuracy of this technique in vitro. Nine three-dimensional stereolithographic skull models were used to design the templates and titanium microplates and to simulate the operation. Cone beam computed tomography (CBCT) scans of the skulls were acquired preoperat...

OBJECTIVES The objective of the present systematic review was to test the hypothesis of no difference in transverse skeletal and dental arch expansion and relapse after segmental Le Fort I osteotomy versus surgically assisted rapid maxillary expansion. MATERIAL AND METHODS A MEDLINE (PubMed), Embase and Cochrane library search in combination with a hand-search of relevant journals was conduct...
