[Comparative study of primary and secondary management of flexor tendon injuries]

In 1974 a replantation service started at the authors' department. Before that time the treatment of flexor tendon injuries was mainly performed secondarily. Therefore, the authors had the opportunity to compare patients after primary and secondary surgery. In 52 primarily and 22 secondarily treated patients the technique of Kleinert was used. Following issues were investigated: functional results, decrease of grip strength, influence of early mobilization on sensibility restoration in cases of nerve injury, relation between sensitivity to cold and vessel and nerve injuries, duration of physiotherapy and disability. The damage of only one finger might lead to decrease of grip strength. Primary surgery was superior to secondary surgery. Early mobilization in cases of additional nerve injuries did not affect sensibility restoration. Poor sensibility increased the chance of cold sensitivity. The duration of physiotherapy and of disability depended on the need for second procedures such as tenolysis which was more common in the group of secondarily treated patients.
