Lesions of the biceps pulley.

BACKGROUND Lesions of the biceps pulley and instability of the long head of the biceps tendon are common diagnoses in patients with anterior shoulder pain. PURPOSE To analyze the pathoanatomy of the biceps reflection pulley ("pulley") in consecutive patients undergoing shoulder arthroscopy. STUDY DESIGN Cohort study (prevalence); Level of evidence, 2. METHODS Prospective data were collect...

The effect of partial A2 pulley excision on gliding resistance and pulley strength in vitro.

PURPOSE The purpose of this study was to investigate the effect of partial excision of the A2 pulley on the gliding resistance and the strength of the residual pulleys in a human in vitro model with or without tendon repair. METHODS We used 32 cadaveric human fingers from 11 cadavers. The A2 pulley was excised successively 25%, 50%, and 75%, cutting either from the distal toward the proximal ...

A comparative study of A1 pulley compliance.

BACKGROUND Trigger finger is most common in the ring finger, but the reason for this is not known. We hypothesized that the compliance of the A1 pulley might be one of the factors responsible for this phenomenon. The purpose of this study was therefore to compare the compliance of the normal A1 pulley of the thumb, index, middle, ring and little fingers using human cadavers. METHODS Eight nor...
