The purpose of this study was to determine whether circumferential taping of the base of the finger increases the A2 pulley's load to failure in a model simulating a rock climber's grip. Nine pairs of fresh-frozen cadaveric hands, 20 to 47 years of age, were rigidly mounted in a specialized jig that maintained the finger in the climber's "crimp" position. Two of the four fingers of each hand were reinforced over the A2 pulley with three wraps of cloth adhesive tape. ⋯ Of the 72 fingers studied, complete data were available for comparison of 22 pairs of fingers. No statistically significant difference in load to A2 pulley failure was noted between the taped and untaped finger pairs. Based on our findings we do not support taping the base of the fingers as a prophylactic measure against flexor tendon sheath injury in the climbing athlete.
