TLDR
The length, breaking strength, and tensile strength of each of the annular fibro-osseous pulleys of digital flexor sheath in ten fresh human cadaver specimens were measured and the first annular pulley and the fourth annularity pulley were found to be the strongest.Abstract:
Summary The length, breaking strength, and tensile strength of each of the annular fibroosseous pulleys of digital flexor sheath in ten fresh human cadaver specimens were measured. The first annular pulley and the fourth annular pulley were found to be the strongest, while the second annular pulley was the weakest. The design of artificial pulleys should reproduce the strength of the first annular and fourth annular pulleys. Suggested minimum requirements for the breaking strength of artificial implant pulleys may be made based on these studies.read more

Development of flexor tendon surgery: twenty-five years of progress.
TL;DR: In the early 1960s, it was universally recommended that tendons divided in the digit (then referred to as “no man's land”) should not be repaired as discussed by the authors.
Journal ArticleDOI
The scientific basis for advances in flexor tendon surgery.
TL;DR: This article attempts to review many of the important scientific reports dealing with flexor tendons that have been published during the last three-plus decades and indicate how those works have improved the management of these difficult injuries.
Journal ArticleDOI
Flexor tendon entrapment of the digits (trigger finger and trigger thumb).
TL;DR: Information from the medical literature on aspects of flexor tendon entrapment of the digits likely to be of interest and relevant to occupational medicine practitioners are summarized.
Journal ArticleDOI
Biomechanical properties of the crimp grip position in rock climbers
TL;DR: The largest amount of bowstringing was caused by the flexor digitorum profundus tendon in the crimp grip position being less using slope grip position (PIP joint extended), and increase of force in one finger holds by the quadriga effect was shown using crimp and slope Grip position.

Palmar aponeurosis pulley.
Paul R. Manske,Peggy A. Lesker +1 more
TL;DR: The transverse fascicular fibers and paratendinous bands of the palmar aponeurosis are positioned at the proximal margin of the flexor tendon sheath and appear to function as a palmar AP oneurosis pulley in conjunction with the first and second annular pulleys of the digital flexor mechanism.

The mechanical properties of bone
TL;DR: BONE is the material with which the orthopaedic surgeon deals and some knowledge of its mechanical properties is of importance for an understanding of the mechanism and management of fractures, as well as the design of prosthetic or orthotic appliances and protective gear.

Flexor-tendon grafts in the fingers and thumb. A study of factors influencing results in 1000 cases.
Joseph H. Boyes,Herbert H. Stark +1 more
TL;DR: Fingers treated by primary wound closure and insertion of a tendon graft as a secondary procedure had significantly better results than those treated by grafting after an attempted primary tendon repair had failed.

Free tendon grafts in secondary flexor tendon repair.
TL;DR: This discussion discusses the restoration of a strong, free gIiding tendon of sufficient ampIitude to permit the finger to be Aexed in coordination with the other fingers through a usefu1 functiona range in secondary repair.
