Summary
We have operated on 51 old injuries with abduction instability of the metacarpophalangeal joint of the thumb. The time from injury to operation was 8 weeks to 5 years. Ligament repair was made in 29 cases. In 22 cases arthrodesis of the joint was performed because of primary unsuccessful operation or arthrosis of the joint.
The patients were followed-up for 6.9 years on average. Twenty-three patients with ligament repair were satisfied, while 6 patients were not satisfied; 4 having a disabling instability and 2 complaining of pain and stiffness of the joint. By stress radiography only 15 of the 29 patients had a stable joint. All the patients with arthrodesis of the joint were satisfied, having a painless and well-functioning thumb.
Zusammenfassung
Wir haben 51 alte Verletzungen des ulnaren Kollateralbandes mit Abduktionsinstabilität im Daumengrundgelenk operiert. Die Zeit von der Verletzung his zur Operation lag zwischen 8 Wochen und 5 Jahren. Eine Ligamentrekonstruktion wurde in 29 Fällen gemacht. In 22 Fällen wurde eine Arthrodese wegen primär mißlungener Operation oder Arthrose des Gelenkes gemacht.
Die Patienten wurden im Schnitt 6,9 Jahre beobachtet. Dreiundzwanzig Patienten mit Ligament-rekonstruktion waren zufrieden, während 6 Patienten unzufrieden waren, 4 davon hatten eine invalidisierende Instabilität and 2 klagten über Schmerzen und Steifheit des betreffenden Gelenkes. Eine Funktionsaufnahme unter Belastung des ulnaren Kollateralbandes im Daumengrundgelenk zeigte ein stabiles Gelenk bei 15 der 29 Patienten. Alle Patienten mit einer Arthrodese waren zufrieden, weil sie einen schmerzlosen, gut funktionierenden Daumen hatten.
