Abstract

OBJECTIVE:

The closed traumatic rupture of finger flexor tendon pulleys in rock climbers appeared as a new complex finger trauma in the mid 1980s. The objectives of this study are to characterize this injury and to describe diagnostic and therapeutic guidelines. A grading system for the severity of pulley injuries was developed and used to set therapeutic pathways.

METHODS:

Six hundred four injured rock climbers were prospectively evaluated from January 1998 to December 2001 with a questionnaire and standard examination protocol. Diagnostic ultrasound was performed in all rock climbers with finger injuries; if necessary, an additional magnetic resonance imaging was done. All pulley injuries were graded according to an introduced pulley-injury score (grade 1-4).

RESULTS:

Three of four of the most frequent injuries were related to the fingers: pulley injuries accounted for 20%, tendovaginitis for 7%, and joint capsular damage for 6.1%. One hundred twenty-two (20.2%) rock climbers presented an injury of the flexor tendon pulley system, 48 had pulley strains, and 74 had ruptures (a single rupture in 90.5% and multiple pulley ruptures in 9.5%). According to the pulley-injury score, 39% were grade 1, 25% were grade 2, 30% were grade 3, and 6% were grade 4 injuries.

CONCLUSION:

Pulley injuries were the most frequent injuries in rock climbers. Whereas grade 1-3 injuries respond well to conservative treatment, grade 4 injuries require surgical repair. We recommend the "loop and a half" technique of Widstrom and colleagues and, alternatively, the Weilby repair. We also recommend postoperative initial immobilization and early functional treatment under external pulley protection.
