BACKGROUND AND PURPOSE The primary event preceding the onset of symptoms in spontaneous osteonecrosis in the medial femoral condyle (SONK) may be a subchondral insufficiency fracture, which may be associated with underlying low bone mineral density (BMD). However, the pathogenesis of SONK is considered to be multifactorial. Women over 60 years of age tend to have higher incidence of SONK and lo...

Patellar fracture is a relatively uncommon fracture especially the vertical sagittal type. In cases of high energy trauma injury, it is usually associated with fracture of ipsilateral distal femur or proximal tibia. However, the combination of vertical sagittal fracture patella and ipsilateral fracture lateral condyle is very rare. This necessitates judicious diagnosis and appropriate managemen...

Fixation of an osteochondral fracture after acute patellar dislocation is an infrequent form of treatment. Likewise, the location of this fragment in the lateral region of the lateral femoral condyle, functioning as a free body, is uncommon. The aim of this study was to present a case of osteochondral fracture of the patella at an unusual site, along with the therapy used and the clinical follo...

Almost all reported cases of longitudinal radioulnar dissociation have involved fracture of the radial head, rupture of the interosseous membrane, and disruption of the distal radioulnar joint, although unusual patterns of Essex-Lopresti injury have also been described. To our knowledge, this is the first report of a chronic Essex-Lopresti variant including fracture of the capitellum. A displac...

background: intra-articular t- type or y- type fractures of the distal end of the humerus are relatively rare, and consequently few surgeons will be able to attain extensive experience with the surgical treatment of these injuries. the current emphasis is on operative intervention with rigid internal fixation and early mobilization. methods: in this prospective and retrospective study, we revie...

We reviewed 22 children with cubitus varus who had been treated by a reverse V osteotomy and fixation by cross-pinning and wiring. The mean pre-operative humeral-elbow-wrist angle was -16.9 degrees (-25 degrees to +9 degrees ) and at the latest follow-up it was +7.3 degrees (-2 degrees to +14 degrees ). No child had a lateral prominence greater than 5 mm after correction. An excellent result wa...

Avulsion fractures of the posterior cruciate ligament (PCL) are uncommon. On the basis of the site of damage of the PCL, hyperflexion, pretibial trauma, and hyperextension are proposed as mechanisms of PCL injuries. On the other hand, avulsion fractures of the tibial condyle are also rare. We report a PCL-mediated avulsion fracture of the lateral tibial condyle along with the tibial insertion o...

background: this is to assess one of the rare complications after total knee replacement and to assess risk factors of failure.methods: 11 patients with varus knee and an average age of 67 years underwent tka between 2005 and 2013. all patients returned with a sudden sharp knee pain, disability to walk and significant decrease in rom about 4 to 8 weeks after surgery. radiographic examination re...

Open reduction and internal fixation with Kirschner (K) wires has been reported as an efficient and convenient technique for pediatric lateral condyle distal humeral fractures. However, no single study has been large enough to definitively determine whether the K-wires should be buried or unburied. Therefore, we performed a meta-analysis pooling the results from several clinical trials to compa...
