Abstract
Between 2005 and 2006, ten patients with flexor digitorum profundus zone II injuries were included. The mean age was 41 (19-84) years. One thumb, two index, four middle, one ring and two little fingers were injured. Repair method comprised four-strand core suture and 6-0 circumferential sutures. Post-operative rehabilitation included immediate active extension, progressive passive full flexion and active hold in dorsal block splint. Follow-up was four (three to seven) months. Grip strength, pinch strength, ROM was 90% (70%-90%), 90% (60%-110%) and 90% (80%-100%) of normal digit, respectively. Mayo wrist scores were five excellent, two good and three fair. All patients were satisfied. Compared with another group of ten patients with the same suture method and Kleinert splintage, grip strength, pinch strength and ROM were 50%, 40% and 40% of normal side, respectively. All differences between these two groups were statistically significant (p < 0.01) by paired samples T-test. There was no re-rupture.
