Capitellar osteochondral impaction fractures of the humerus are an uncommon injury and not encompassed by commonly used classification systems, such as that of Bryan and Morrey. Only a few cases of capitellar osteochondral impaction fractures have been reported. We report a case of a 53-year-old female with a capitellar osteochondral impaction fracture. The osteochondral fracture fragment of the capitellum was impacted and there was a step-off on the articular surface. Recovery of congruence in the capitellar articular surface was necessary. Satisfactory clinical and radiological results were obtained through the ‘lever arm’ reduction of the fracture fragment with a small osteotome and fixation with ‘raft’ K-wire.
The purpose of the current study was to investigate the results of occult fractures in the subtalar joint which were detected in delay and to find out a way of early detection. The occult osteochondral fractures of the subtalar joint are known to be associated with dislocation and to have a poor prognosis. We treated ten patients who had the occult fractures that were not associated with dislocation. Nine fractures involved posterior facet with a displaced osteochondral fracture. Seven patients lost motion in the subtalar joint completely, and arthrodesis were performed. Three subtalar joints retained some motion and were treated with physiotherapy, which improved the movement and pain. The early detection of fracture was important for the prognosis. We note the "early warning"signs of the patients who have massive swelling without definite bone injury, and who had a failure to regain the subtalar motion after immobilization. The subtalar joint should be imaged with CT or MRI. At first, aggressive physiotherapy should be considered. Arthrodesis should be considered as a final option.
Osteochondral fracture is an attached fragment of subchondral bone become partially or completely separated from the underlying bone. Accurate diagnosis of osteochondral fracture of the talus,mainly caused by trauma, is difficult because osteochondral lesion is not detected easily on the roentgenographic examination. Osteochondal fracture is intraarticular fracture, thus operative approach and fixation is technically difficult and requires talus, with subchondral bone curettage through percutaneous extraarticular transtalar approact under the C-arm guide without arthrotomy in three cases of minimally detached or elevated osteochondral fragment. And two cases of partially detached osteochondral fragment treated by bone peg fixation with arthrotomy. We obtained good functional results at the follow-up of a mean of 1 year and 5 months. We believe that the subchondral curettage and bone peg fixation are excellent treatment methods for osteochondral fracture of the talus.
