The 19 pulleys in sequence result into 57 2nd-order equations with 219 solutions, of which only one delivers all positive results. The model was used to detemine the force distribution along the axial pulley length with respect to different tendon angles, in order to simulate different finger ...
With the rise in popularity of the sport of rock climbing in the 1980's, closed finger pulley ruptures began to appear. Competitive climbers routinely put their entire body weight (and more during maneuvers) on one or two flexed fingers. Pulley lesions have been shown to be the single most...
The patient was an 18-year-old male rock climber who was referred to a hand surgeon with a chief complaint of worsening pain in the proximal phalanx of his right middle finger. Past surgical history for the patient included surgical reconstruction of the A2 and A3 pulleys of the left middle...

On the arm 3 is also secured a finger 8 inclined both to the shaft axis and to the running direction of the belt. A chain-wheel 9, rigidly connected to the arm 3, and a chain 10 are employed to operate the device. Intermediate spur-gearing, held in adjustable brackets, may be ...
A second arm 56 engages a finger 76 pivoted to a projection so that it is actuated on the passage of the arm 56 in one direction only, and oscillates a rock-shaft 68 to control a clutch 20 and a stop 66. The blank 8 is connected by bevelgearing with the dividing-wheel 1, Fig. ...
