Flexor tendon tenolysis consists of the surgical release of adhesions formed
around tendons that persist despite splinting and appropriate rehabilitation.
The aim of this study was to evaluate the increase in active range of motion
following flexor tenolysis in zone II and to document the ensuing complications.
Sixty patients (75 fingers) underwent zone II flexor tenolysis following flexor
tendon injury, with or without dorsal tenolysis or PIP arthrolysis. Tenolysis
cases following tendon graft or replantation were excluded. Both passive and
active ranges of motion were measured at metacarpophalangeal, proximal and distal
interphalangeal joints preoperatively and postoperatively at 6 weeks (57
patients) and 3 months (40 patients). These measurements were completed by a
functional evaluation using the Strickland classification. Any complications were
noted. Mean preoperative total active motion (TAM) was 128 degrees , increasing
postoperatively to 188 degrees at 6 weeks and 192 degrees at 3 months. Mean
increase in TAM for patients undergoing tenolysis only was 60 degrees , compared
to 90 degrees in those undergoing tenolysis with arthrolysis. The functional
outcome at 6 weeks was excellent in 23% of cases, good in 47%, average in 20% and
poor in 10%. Deep flexor tendon rupture occurred in seven cases. Palmar flexor
tenolysis can improve active range of motion of the fingers, and consequently,
function.
