L. Miller et Dp. Mass, A comparison of four repair techniques for Champer's chiasma flexor digitorium superficialis laceuations: Tested in an in vitro model, J HAND S-AM, 25A(6), 2000, pp. 1122-1126
The relative strengths of 4 methods for repair of the flexor digitorum supe
rficialis tendon were examined in 14 fresh-frozen cadaver hands (40 tendons
). All tendons underwent sharp zone II transection at Camper's chiasma. All
transections were repaired with 4.0 Ethibond (Ethicon Inc, Sommerville, NJ
) using modified Becker, modified Kessler, horizontal mattress, or simple s
utures. Flexion of the repaired digit at a constant excursion rate was rend
ered up to tendon rupture. The modified Becker technique withstood breaking
forces (57.9 N) significantly greater than the other techniques examined.
Forces up to 34 N have been measured in vivo during unresisted active finge
r motion. Thus, the modified Becker technique appears to provide adequate s
trength for early active flexor digitorum superficialis motion. Copyright (
