We believe that osteochondritis dissecans of the capitellum can be classified as stable or unstable. Stable lesions that healed completely with elbow rest had all of the following findings at the time of the initial presentation: an open capitellar growth plate, localized flattening or radiolucency of the subchondral bone, and good elbow motion. Unstable lesions, for which surgery provided significantly better results, had one of the following findings: a capitellum with a closed growth plate, fragmentation, or restriction of elbow motion of >or=20 degrees . For large unstable lesions, fragment fixation or reconstruction of the articular surface leads to better results than simple excision.

Sonography in the field can provide an opportunity to detect and treat elbow injuries before they become more advanced.

Because the sliding distance increased in the intramedullary type in the lateral view of unstable fractures, an accurate reduction in the lateral view at surgery is important, particularly in unstable fractures.

The current study investigated the incidence of complications after surgery for distal radial fractures. This multicenter retrospective study was conducted at 11 institutions. A total of 824 patients who had distal radius fractures that were treated surgically between January 2010 and August 2012 were identified. The study patients were older than 18 years and were observed for at least 12 weeks after surgery for distal radius fractures with a volar locking plate. Sex, age, fracture type according to AO classification, implants, wrist range of motion, grip strength, fracture consolidation rate, and complications were studied. Analysis included 694 patients, including 529 women and 165 men, with a mean age of 64 years. The mean follow-up period was 27 weeks. The fracture consolidation rate was 100%. There were 52 complications (7.5%), including 18 cases of carpal tunnel syndrome, 12 cases of peripheral nerve palsy, 8 cases of trigger digit, 4 cases of tendon rupture (none of the flexor pollicis longus), and 10 others. There was no rupture of the flexor pollicis longus tendon because careful attention was paid to the relationship between the implant and the tendon. Peripheral nerve palsy may have been caused by intraoperative traction in 7 cases, temporary fixation by percutaneous Kirschner wires in 3 cases, and axillary nerve block in 1 case; 1 case appeared to be idiopathic. Tendon ruptures were mainly caused by mechanical stress. [Orthopedics.2016; 39(5):e893-e896.].
