Abstract

Bleeding in the calf or ankle joint may lead to ankle equinus deformity, particularly in childhood and during adolescence. We assessed the long-term functional and radiographic results after Achilles tendon lengthening for ankle equinus deformity in hemophiliacs. Between 1975 and 1986, 30 hemophilic patients with pes equinus were surgically managed by Achilles tendon lengthening. Of these, 23 were followed up prospectively twice a year for an average of 13 (1-24) years. The mean age at operation was 29 (12-46) years. The clinical results were documented according to the score of the Advisory Committee of the World Federation of Hemophilia (WFH), while radio-graphs were evaluated using the Pettersson score. On average, preoperative ankle equinus deformity was 21 (5-55) degrees. Mean range of motion was 21 (5-42) degrees prior to surgery. At the first postoperative examination 1 year after surgery, 21/23 cases were improved, and 9/21 reached dorsiflexion to at least neutral position. At the last follow-up, ankle equinus deformity was 10 (4-20) degrees on average. 20/23 patients still showed significant improvement compared to their condition before surgery. 7 patients still had complete correction of the equinus deformity, while ...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
