A 33-year-old Caucasian woman came to our attention complaining of lateral knee pain on the left side, severe external instability associated with varus malalignment, and difficulties in weight-bearing activities. The symptoms had appeared following two lateral meniscectomies on her discoid meniscus, performed elsewhere. The patient was initially submitted to an allograft meniscus transplantati...

legg-calvé-perthes disease (lcpd) is an idiopathic osteonecrosis of the femoral head with variable complications and resultant deformity of the femoral head and osteoarthritis. suggested risk factors are acetabular retroversion, obesity, latitude, hyperactivity, and coagulopathy. the most commonly applied classification is based on radiolucency in the lateral pillar of the femoral head, which i...

The clinical results after high tibial osteotomy for the treatment of symptomatic varus gonarthrosis are unpredictable. Although preoperative gait analysis has been shown to be useful in predicting successful outcome after high tibial osteotomy, there are no readily available preoperative clinical tests for predicting success. The authors did a study to determine the effects of an offset short-...

  Background: There are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. In the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. Methods: Forty patients with valgus knee malalignment were randomly assigned to two equal nu...

An osteotomy must be performed in almost all types of external nose correction. By mobilising the bony skeleton, the nose may be sculpted into the desired shape and position. The osteotomy is carried out as gently as possible in an effort to minimize postoperative swelling and soft tissue bleeding. Finger and sharp chisels are used. Nasal bones are accessed through a short intercartilaginous in...

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...

A 68-year-old man with right knee varus osteoarthritis was treated by lateral closed-wedge high tibial osteotomy. A correction loss with non-union occurred 6 months after surgery and a re-correction osteotomy was performed. Removing the proximal screws of the lateral plate, a medial opening-wedge re-osteotomy was performed. Arthroscopically harvested osteophytes were used to fill the gap after ...

A prospective investigation of the effects on the medial and lateral neurovascular structures of the rearfoot after percutaneous posterior calcaneal displacement osteotomy was performed using 20 below the knee fresh frozen cadaver specimens. This anatomic study aimed to examine the medial and lateral neurovascular structures to determine whether they were jeopardized during execution of the ost...

OBJECTIVE To measure the variation in posterior tibial slope angle and patellar height in patients who underwent proximal tibial valgus-producing osteotomy using the medial-opening wedge technique. METHODS Anteroposterior panoramic radiographs of the lower limbs and lateral radiographs of the knee obtained before and after tibial valgus-producing osteotomy on 46 patients with unicompartmental...
