Fdp Tendon Rupture

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.

Complete rupture of flexor pollicis longus tendon of thumb noted at the base of proximal phalanx with retracted ends and intervening mild PD fat sat hyperintense edema.

Fdp tendon rupture. Liu and Yang 42 reviewing 15 cases of tendon graft for isolated FDP tendon rupture obtained an average of 33 of DIP active flexion. This usually occurs as a result of forced extension during active flexion. Flexor Tendon Injuries are traumatic injuries to the flexor digitorum superficialis and flexor digitorum profundus tendons that can be caused by laceration or trauma.

An FDP rupture is when the flexor digitorum profundus FDP tendon is torn. From 8-12 weeks after surgery your splint can be discarded and resistance will be gradually added to your exercise regime. This occurs in regions where the tendon is covered by tenosynovium extensor retinaculum carpal tunnel and digital flexor sheath.

In the hand wrist and forearm lacerations are the most common cause of flexor tendon injury. These injuries can be caused by both mechanical and pathologic processes and traumatic ruptures result from either direct indirect or repetitive injuries. Zone Flexor Tendon Injuries Primary Repair Secondary Reconstruction.

Main complications were loss of PIP joint extension more than 30 in 27 of the cases of Liu et al 42 less than 10 in 55 of the cases and more than 10 in 9 of the cases of McClinton et al 41.

The tendon may be directly invaded by the synovial pannus. Sonographic features of partial tear 50 of the flexor digitorum profundus tendon above the proximal interphalangeal joint. Rupture may also result from ischemia caused by pressure from underlying proliferative synovitis.

The tear extends for about 68 mm and a small amount of fluid and hypoechogenic material is seen with the tear region. A cut flexor tendon injury is a serious injury. Flexor hallucis longus FHL tendon injuries can range from tenosynovitis to partial tears and complete ruptures.

In this article we explore what an FDP rupture is explaining the symptoms diagnosis and treatment in more detail. In these cases the tendon is often cut into two pieces. Another mechanism of injury is a rupture rather than a laceration for example the FDP tendon has ruptured from its insertion at the distal phalanx - usually this is caused by a closed mechanism of injury.

A torn or cut tendon in the forearm at the wrist in the palm or along the finger will make it impossible to bend one or more joints in a finger. The wound may be small but the large forces carried by flexor tendons and the tendency for the repaired tendon to stick to the walls of the tunnel mean that despite a skilled repair and good hand therapy many fingers do not regain full movement. This is one of the most risky times for tendon rupture because it is easy to overuse the hand when the splint first comes off.

In some cases the flexor tendon injury can occur if the tendon end pulls away from bone if the tendon ruptures due to wear or if the tendon-muscle interface separates. Because flexor tendons are very close to the surface of the skin a deep cut will most likely hit a flexor tendon. The FDP tendon runs from the forearm to the hand.

Diagnosis is made clinically by observing the resting posture of the hand to assess the digital cascade and the absence of the tenodesis effect. Activities using your hand can slowly be increased. Flexor Digitorum Profundus Rupture.

Problems that can occur include. The only solution in these cases is either to use a tendon graft or a two-stage tendon re construction using either silicone rods or Hunter tendon implants Pulvertaft 1956 Hunter 1984 Wil son 1985 Soucacos 1995 1995. But repairing the tendon is better than not repairing it.
