2022年8月10日 · Flexor Tendon Injuries are traumatic injuries to the flexor digitorum superficialis and flexor digitorum profundus tendons that can be caused by laceration or trauma. Diagnosis is made clinically by observing the resting posture of the hand to assess the digital cascade and the absence of the tenodesis effect.

- results from forceful hyperextension of DIP joint w/ FDP in maximal contraction; - classic examples include pts injured by the sudden jerk of a rope, such as starting a lawnmower or retraining an animal; - tendon may rupture directly from its insertion into bone, or it may avulse bone fragment from base of distal phalanx;

Closed ruptures of the flexor digitorum profundus (FDP) tendon cause a loss of active flexion at the distal interphalangeal joint. Commonly referred to as a ‘jersey finger’ because of its association with tackling sports, the distal aspect of FDP is avulsed from its insertion on the distal phalanx in zone I, with or without a fragment of bone.

injury involving the flexor digitorum profundus Avulsion-type (FDP) tendon (ie, jersey finger injury) is relatively common and is seen in athletes and nonathletes. The mech-anism of injury includes forced hy-perextension of the distal interpha-langeal (DIP) joint while the finger is actively flexing. The common term is.

The flexor digitorum superficialis [FDS] and flexor digitorum profundus [FDP]) originate proximally in the forearm, at the medial epicondyle of the elbow. They, along with flexor pollicis longus (FPL) and the median nerve, travel through the carpal tunnel …

There is a partial tear involving more than 50% of the distal portion of flexor digitorum profundus tendon, about 5 mm distal to the proximal interphalangeal joint. The tear extends for about 6.8 mm and a small amount of fluid and hypoechogenic material is seen with the tear region.

Flexor digitorum profundus avulsion generally occurs at the tendon's insertion at the distal phalanx. The injured finger cannot actively be flexed at the distal interphalangeal joint. X-rays are needed to rule out avulsion fracture. Treatment is with surgery. The injury occurs primarily in football and other contact sports (eg, rugby).

While a traumatic avulsion of the FDP from its insertion at the distal phalanx is a common entity (also called Jersey Finger), this tendon usually does not rupture along its body unless weakened by a pathological condition .

2019年3月15日 · Closed flexor digitorum profundus (FDP) avulsion injuries are one of the more common forms of Zone I flexor tendon injuries. The mechanism of tendinous avulsions involves forced hyperextension of a maximally flexed distal interphalangeal joint (DIPJ).

2021年7月26日 · In this video we'll discuss the injuries and rehab activities associated with the flexor digitorum profundus, or FDP. We’ll start with relevant anatomy, then move on to internal risk factors, causes of injury, testing and symptoms, and finally how to …
