high tibia osteotomy is a common procedure in orthopedic surgery. a precise overview on indications, patients selection, pre-operative planning, surgical technique, methods of fixation, and complications have been presented. this paper focused on the points that should be considered to achieve good long-term outcomes. high tibia osteotomy is a common procedure in orthopedic surgery. a precise o...

STUDY DESIGN A new surgical technique of cervical osteotomy to correct an extension deformity of the cervical spine is described, and a case is reported. OBJECTIVES To emphasize the disparate effect of osteotomy level on sagittal balance and gaze angle in surgical correction of global kyphotic deformity, and to describe a new surgical technique. SUMMARY OF BACKGROUND DATA Previous reports o...

UNLABELLED BACKGROUND Achieving precise implant alignment is crucial for producing good outcomes after total knee arthroplasty (TKA). We introduce a simple method for confirming the accuracy of tibial osteotomy during TKA. FINDINGS Two metallic markers were placed on the skin 20 cm apart, one on the tibial tuberosity and other on the tibial crest, points that are easily identified and palp...

BACKGROUND Edema and ecchymosis are common complications of rhinoplasty. Modifications to osteotomy may reduce edema and ecchymosis and ameliorate postoperative discomfort in patients who undergo rhinoplasty. OBJECTIVES The authors performed osteotomy with conventional instruments or with an ultrasonic device and compared these methods with respect to the severities of ecchymosis and edema in...

BACKGROUND Supramalleolar osteotomy (SMOT) is a well-accepted treatment method for mid-stage varus ankle osteoarthritis (OA). However, few studies have examined the role of fibular osteotomy in SMOT. The objective of the current study was to compare the biomechanical and clinical outcomes of SMOT with and without fibular osteotomy. METHODS Eight cadaveric lower legs with 10° varus/valgus SMOT...

Despite the fact that common surgical techniques for the treatment of genu varum usually correct the malalignment in the affected knee, these methods have significant complications and cause problems in the long term. Retro-tubercle opening-wedge high tibial osteotomy is among the newer techniques for the treatment of genu varum. The goal of this study was to compare the results of retro-tuberc...

OBJECTIVES The aim of this study was to investigate the displacement and stress distribution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. MATERIALS AND METHODS Three-dimensional (3D) finite element model of a maxilla was constructed and an expansion force of 100 N was applied to the left and right molars and premo...

Balancing and surgical exposure of a severe varus knee during total knee arthroplasty (TKA) can be difficult. Use of a medial epicondylar osteotomy to solve these problems has been reported. This study compared knee stability in cadaveric specimens after TKA, after medial epicondylar osteotomy, and after conventional subperiosteal release of the medial collateral ligament (MCL). Five cadaveric ...

The Le Fort II osteotomy is a relatively rare operation. The posterior wall osteotomy of the maxillary sinus (MS) is often difficult for Le Fort III. We developed the transmaxillary sinus approach (TSA) for the Le Fort II osteotomy that cuts the posterior wall of the MS directly. This report illustrates this easy-to-use procedure for the Le Fort II osteotomy in syndromic craniosynostosis. This ...
