Rupture of the extensor pollicis longus tendon in undisplaced Colles type fracture.

Ucl qf fixtures. The first is after a fracture of the wrist in particular where the fracture is not very displaced. Undisplaced wrist fracture - interrupts blood supply at a watershed area - between 3 weeks and 3 months post injry. It is postulated that the EPL tendon was weakened by prolonged repetitive activity causing long-term mechanical attrition at work and subse- quently ruptured.

Current literature suggests that tendonitis of the extensor pollicis longus EPL is a rare condition that has a high rate of progression to rupture. Jul 05 2016 The long extensor tendon to the thumb is called the Extensor Pollicis Longus EPL. This tendon straightens the end joint of the thumb thumbs up or hitch hikers sign see Figure 1 and also helps pull the thumb in towards the index finger.

Clinical and microangiographic studies on rupture of the EPL tendon after distal radial fractures. This study documents the prodrome of impending EPL rupture in patients with prior nondisplaced distal radial fracture. Jun 06 2020 EPL tendon rupture may not significantly affect the thumb interphalangeal IP joint extension because this motion is controlled by the intrinsic muscles and by the EPL.

Sharing his introspections about EPL rupture he calmly states The damage to the extensor tendon around the bony prominence at the back of the wrist called Listers tubercle when it extends to the thumb is referred to as EPL rupture. Longitudinal incision may be utilized across joints on the dorsum of digits unlike the palmar side. Distal phalanx of thumb first passes around Listers tubercle of the radius.

Why does it rupture. Spontaneous rupture of the EPL tendon is rather rare when it occurs in occupational work activity without injury to the underlying bone or arthritic changes. A retrospective study identified patients with EPL tendonitis or tendon rupture.

Rupture of the EPL can occur up to 8 weeks after the initial distal radius fracture. The second is in Rheumatoid Arthritis where there is inflammation round the tendon in this area. EIP to EPL tendon transfer.
