BACKGROUND Rotator cuff tears are frequently associated with pathologies of the long head of the biceps tendon (LHBT). Tenotomy and tenodesis of the LHBT are commonly used to manage disorders of the LHBT. METHODS We present an arthroscopic soft tissue LHBT tenodesis associated with a Roman Bridge (double pulley - suture bridges) repair RESULTS Two medial row 5.5-mm Bio-Corkscrew suture anch...

This article provides a general overview of the biomechanical principles associated with hand therapy. Specifically, it reviews the basic topics of material properties (including both theoretical principles and practical concepts), static analysis (including forces, moments, muscle forces, and Newton's laws), and ends with a clinical example involving analysis of the risk of damage to the A3 pu...

We report a case of post-traumatic trigger finger due to a partial longitudinal tear of the flexor digitorum superficialis. The suspect came from the clinical history and the young age of the patient. It was successfully treated with tendon flap suture and pulley A1 release.

The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29) performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized. Average amplitude of the electromyographic root mean square of Tr...

The tarsal flexor system, a novel system of retinacular structures, is described for the first time based on morphological and ultrastructural examinations of several Neotropical harvestmen (Opiliones: Laniatores). The tarsal flexor system is made up of many individual pulleys that function to maintain close apposition between the tendon and internal ventral surface of the cuticle in the tarsus...

OBJECTIVE Know the results of percutaneous release of trigger digits by using full handle knife 15 degrees. MATERIAL AND METHOD The author identified 510 cadaveric digits to find the anatomical landmark of Al pulley that relates to the knuckle and measurements of A1 pulley lengths. The proximal margin of the Al pulleys on the perpendicular line from the knuckle to the palm was in the same lin...

Bray JJH, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220937 Description A 53-year-old, right-handed man was referred to orthopaedic clinic with a 1-year history of progressive ‘trigger-like’ symptoms and eventual locking of the right ring and middle fingers. There was no history of trauma or joint problems. Medical history included stable chronic kidney disease and well-controlled hypertens...
