Osteochondromas are overgrowing or bone projection covered by cartilage which appears most commonly in the metaphysis of long bones, but also have been reported on the diaphysis, in flat bones and in vertebrae [1], grow during childhood through adolescence, but usually growing ends when the epiphyseal plates close.If the growth happen in adulthood suggests the diagnosis of malignant transformat...

The hybrid fixators, or the fixators that use the thin wire fixation in the periarticular fragment combined with the half-pin fixation in the diaphysis, have made the multiplanar external fixation easier to use and thus growing in popularity. However, the configuration of the ideal hybrid has not been elucidated yet. The purpose of this study was to determine the stiffness characteristics affec...

Angular deformity of the thumb is most often caused by a delta phalanx or a longitudinally bracheted diaphysis in a triphalangeal thumb. In some angled thumb, however, triangular-shaped secondary ossification center can cause the deformity, which can be called “abnormal triangular epiphysis” of the thumb. A few clinicians have reported this entity, but they do that utilise this term instead cla...

We present an unusual cause of anterior tibial pain in a 24-year-old professional international football player who was found to have a synostosis of the middle-third of the diaphysis of the tibia and fibula. This is a rarely described phenomenon. Conservative treatment is the recommended treatment of choice, but this failed in our patient. Resection produced resolution of symptoms; he remained...

   Aneurysmal bone cyst (ABC) is a benign expansile bone tumor, most commonly involving the medulla of long bones. ABC rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary ABC changes, and telangiectatic osteosarcoma. Both of these are sometimes mistaken mic...

Gustilo type IIIC open fractures of the tibia are high-energy injuries necessitating long treatment periods and usually multiple surgical procedures and eventually resulting in high morbidity rates and even amputations. We present here a case involving a type IIIC open tibial fracture with massive loss of the entire tibial diaphysis, which we treated by performing acute tibialization of the fib...

Methods: Medial meniscectomy was used to induce OA in male Lewis rats. Therapy with zoledronate and human PTH was initiated immediately after surgery. A dynamic weight-bearing system was deployed to evaluate the weight-bearing capacity. At the end of the 10-week study cartilage pathology was evaluated by contrast μCT imaging and histology. Cortical bone geometry at femoral mid-diaphysis was eva...
