Tractus-intermedius-Durchtrennung �ber dem Fingermittelgelenk (sog. Knopflochdeformit�t)

Abstract

The boutonnière deformity was seen in 172 patients of whom 124 were treated surgically. Follow-up of 114 patients after an average of 40 months (6-126 months). Based on the score according to Geldmacher et al. an excellent result was seen in 24, a good in 54, a satisfactory in 22, and a poor result in 14 patients.

Unusual combination of lesions of the traumatic hand: closed central slip laceration of the extensor and interphalangeal thumb joint’s dislocation (a case report)

“…A PIPJ splintage and distal interphalangeal joint,(DIPJ) flexion exercise regime is the mainstay of treatment for closed central slip rupture. However, in established boutonniere deformities that are no longer correctable, surgical release of the PIPJ and reconstruction of the central slip might be the only intervention available to the patient [9, 10]. Actually, diagnosed closed central slip injuries could be treated with extension splinting of the PIPJ - combined with maximum forced active flexion exercises of the DIPJ in order to restore the normal tendon balance and precise length relationship of the central slip and lateral bands.…”

“…Actually, diagnosed closed central slip injuries could be treated with extension splinting of the PIPJ - combined with maximum forced active flexion exercises of the DIPJ in order to restore the normal tendon balance and precise length relationship of the central slip and lateral bands. Another option is the immediate surgical repair of central slip injuries including reattachment of the avulsed central slip using a commercially available bone anchor, and reconstruction of the damaged central slip with adjacent lateral band tissues [10, 11]. …”
