Dynamic splinting after flexor tendon injuries of the hand in childhood

Ninety severed flexor tendons were repaired in 24 boys and 14 girls in a four-year-period at the Department of Pediatric Surgery in Graz. Mean age was 4.9 years. In 16 patients (42%) additional lesions were found. Direct repair was performed with modified techniques of Kirchmayr (23) or Kleinert (8). In four fingers, flexor tendon reconstructions were carried out. Postoperatively, the dynamic Kleinert splint was used for early nonresistive motion, beginning on average on the second postoperative day. Intensive training of motion was performed in physiotherapeutic sessions during a mean period of five months, postoperatively. In five cases tenolysis was performed; in one case a rupture of a sutured tendon had to be corrected. 27 patients (71%) with 42 injured fingers were followed-up on average 2.7 years after the operation. In accordance with the Buck-Gramcko classification, very good results were achieved in 37 cases (88%), and a poor result in one patient (2%). Atraumatic technique, dynamic splinting, consequent physiotherapeutic training by experienced physiotherapists, and well informed parents will yield excellent results after flexor tendon repair in the paediatric age group.
