Isabelle SCHOEFFL : Feasability of a new pulley repair : a cadaver study.

In this study, the feasibility of a new pulley reconstruction was evaluated using a isokinetic loading device on cadaver fingers. 9 fingers from 6 cadaver hands presenting intact pulley systems were compared to 9 fingers from 6 cadaver hands with missing A2 to A4 pulleys, but which featured a repair using the new surgical technique. Each finger was then fixed to an isokinetic loading device. The forces in the flexor tendons were recorded in each finger using a force transducer. The forces recorded in the flexor tendons of the control group were significantly higher than in the operated fingers, but comparable to earlier studies with unoperated fingers. The most common event in the operated fingers was a graft failure. A fracture of the bone due to the used drill hole did not occur. The new pulley reconstruction could represent an alternative to existing reconstructive techniques. The cause for the higher forces recorded in the control group could be attributed to sutures used in the operated fingers. The new pulley reconstruction method may enable reduced extensor tendon irritation as it avoids contact with the extensor hood, and will hopefully prohibit cortical bone loss, a serious side effect in the standard technique.
