Radiological assessments and clinical results of intra-articular osteotomy for traumatic osteoarthritis of the ankle.

Introduction: Traumatic osteoarthritis of the ankle joint caused after malleolar fractures of the ankle and tibial plafond fractures are frequently observed in comparatively young and highly active patients. Since the ankle movement in these patients is in general, comparatively favorable, orthopedists may sometimes have difficulty in deciding on a treatment policy. In our department, when treating traumatic osteoarthritis patients having a movable range within their ankle joints, we proactively applied distal tibial oblique osteotomy (DTOO) developed by Dr.

Comparison of histopathology and preoperative 18F-FDG-PET/CT of osteomyelitis aiming for image guided surgery: A preliminary trial.

Objective: There are currently no robust methods for accurately localizing the infection focus of osteomyelitis. Accumulation of fluorodeoxyglucose (FDG) is nonspecific, and it is well-known that it can indicate inflammatory cells and sites of inflammation, and its effectiveness in detecting osteomyelitis has been reported recently. However, the optimal cut-off value for the Standardized Uptake Value (SUV) in detecting the focus of osteomyelitis through 18F-FDG-PET/CT is not known.

Ankle joint reconstruction by circular frame external fixator for a severely comminuted and contaminated open tibial pilon fracture (AO 43-C3.3). Case report.

A severely comminuted and contaminated open tibial pilon fracture is one of the most challenging fractures we face. Although nowadays conducting multiple operations over various stages is a common treatment option taking into account the possibility of soft tissue damage, a gold standard protocol for severe pilon fractures has not yet been established. This case concerns a 56-year-old gentleman who suffered a severely comminuted and contaminated Gustilo 3b open tibial pilon fracture (AO 43C3.

The Teramoto distal tibial oblique osteotomy (DTOO): surgical technique and applicability for ankle osteoarthritis with varus deformity.

We have devised a medial peri-articular osteotomy, the distal tibial oblique osteotomy (DTOO), and have used this technique since 1994 for ankle osteoarthritis of advanced and late stages associated with varus inclination. This report describes the surgical technique and its applicability. DTOO can be used for cases of varus ankle osteoarthritis with a range of the ankle joint movement of at least 10° or more.

Chipping and lengthening over nailing technique for femoral shaft nonunion with shortening.

Purpose: Chipping and lengthening over nailing (CLON) technique was developed to treat femoral shaft nonunion with shortening more than 10 mm. The purpose of the current retrospective case series was to clarify the effectiveness of the CLON technique on the femoral shaft nonunion following intramedullary nailing.

Methods: Clinical and radiological outcomes in the patients receiving operative treatment for femoral shaft nonunion between August 2012 and December 2016 were retrospectively reviewed using the Refractory Fracture Data Registry at the authors' institution.

Bilateral incidence and severity of acetabular dysplasia of the hip.

Background: Most Japanese patients have secondary osteoarthritis, mainly due to developmental dislocation of the hip (DDH) or acetabular dysplasia (AD). However, the precise pathomechanism of AD remains unknown. The purpose of this study was to investigate the frequency of bilateral AD and determine the correlation of the severity of AD between the right and left hips.
