OBJECTIVE To evaluate whether final ostium size is determined by the osteotomy created during dacryocystorhinostomy (DCR). DESIGN Prospective nonrandomized study. Intraoperative measurements of bony osteotomy were taken during external DCR. Endonasal endoscopy with functional endoscopic dye testing and internal ostium photography were performed 3 months after surgery. RESULTS Fifty patients...

We used a trochanteric slide osteotomy (TSO) in 94 consecutive revision total hip arthroplasties (90 with replacement of both the cup and stem). This technique proved to be adequate for removing the components, with few complications (two minor fractures), and for implanting acetabular allografts (18%) and reinforcement devices (23%). Trochanteric union was obtained in most patients (96%), even...

BACKGROUND Opening wedge osteotomy of the medial cuneiform has become an established intervention for correction of forefoot varus in relation to a flatfoot deformity. The purpose of this study was to use a newly described radiographic measurement to determine the effectiveness and durability of the medial column correction with a plantarflexion opening wedge osteotomy of the medial cuneiform w...

PURPOSE Understanding the anatomy of the pterygomaxillary junction region helps prevent blood loss in Le Fort I osteotomy. Here, we determined the location of the descending palatine artery and the structure of the pterygomaxillary region. PATIENTS AND METHODS The study group consisted of 82 Japanese patients with mandibular prognathism and asymmetry, with and without maxillary retrognathism ...

Forefoot adduction is a common condition between metatarsus adductus, Z-shaped foot and residual clubfoot. This deformity is located in a pure transverse plane at Lisfranc’s joint. Isolated metatarsus adductus is corrected spontaneously for the majority of newborns. In rare uncorrected cases, it could result in Z-shaped foot with a functional hindfoot valgus to equilibrate the resistant metatar...

We reviewed 34 knees in 24 children after a double-elevating osteotomy for late-presenting infantile Blount's disease. The mean age of patients was 9.1 years (7 to 13.5). All knees were in Langenskiöld stages IV to VI. The operative technique corrected the depression of the medial joint line by an elevating osteotomy, and the remaining tibial varus and internal torsion by an osteotomy just belo...

Patellofemoral instability is a common cause of anterior knee pain, especially in younger and more active patients. Treatment of instability varies considerably depending on the patient's symptoms as well as the cause of the instability. Lateral instability has a particularly broad spectrum of treatment algorithms including patellar taping, arthroscopy, lateral release, medial patellofemoral li...

BACKGROUND We describe a procedure for diagnosis and planning for orthognathic surgery based on international standards. A special 2D planning based on lateral cephalograms (Axis Orbital Marker Lines System) realize a transmission to the SAM 2P articulator (3D) by means of the Axis Orbital Plane. METHODS Former intraoperative measurement of the average height of the LeFort I osteotomy plane r...

OBJECTIVE The aim of this anatomical study was to determine if a needle is able to reach the lateral pterygoid muscle during the application of dry needling technique. METHODS A dry needling approach using 2 needles of 50 to 60 mm in length, one inserted over the zygomatic process posterior at the obituary arch (for the superior head) and other inserted below the zygomatic process between the...

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 ...
