Rupture of the flexor tendons of the index finger after Collesʼ fracture. Case report

Delayed rupture of all finger flexor tendons (excluding thumb) following nonoperative treatment of Colles' fracture: A case report and literature review

“…Extensor pollicis longus (EPL) tendon rupture has been documented as a complication in about 1% of closed distal radius fractures and it is thought to be due to attrition or fracture injury to the tendon at Lister's tubercle, 6 while the pathogenesis of the flexor tendons rupture is controversial, although two principal causes have been postulated 21 : 1) the acute partial or total flexor tendon rupture at the time of injury by fracture fragments 1 and 2) chronic attritional rupture 21 due to anterior bone prominence and/or bony 4,6,7,9,11,12,14,16,18,22,23 , ulnar head displaced volarly 5,10,15,17,20, or both simultaneously. 2,10,21 With regard to the acute partial or total flexor tendon rupture, they have been reported to occur shortly after the fracture (range 4 he6 weeks after the injury) and the mechanism was severe initial displacement of fracture fragments or the presence of a bony spur.…”

Flexor Carpi Radialis Tendon Rupture as a Complication of a Closed Distal Radius Fracture: A Case Report

“…[1][2][3][4][5][6][7][8][9][10] Ruptures of the flexor pollicis longus (FPL), flexor digitorum superficialis (FDS), and flexor digitorum profundus (FDP) have been described in case reports as both acute and delayed complications of distal radius fractures. 1,[11][12][13][14][15][16] We describe an unusual case of an acute rupture of a more superficial tendon, the flexor carpi radialis (FCR), in a patient with a closed distal radius fracture. A search of the literature showed no other cases of FCR rupture in association with wrist fractures.…”

Acute Rupture of Flexor Tendons as a Complication of Distal Radius Fracture

“…However, most of these reports were chronic rupture of these tendons. Only Southmayd et al 10) reported a case of rupture of second FDP tendon that occurred soon after a distal radius fracture. In our case, the rupture of In our cases, all acute ruptures occurred in young adults by highenergy injuries.…”

“…Although this ruptures can caused by low-energy injuries, most of reported cases were related with high-energy injuries. 4,7,8,10) However, we think that it is hard to confirm the effect of the mechanism of injury because acute ruptures of flexor tendons following distal radius fracture is very rare. Rather, all distal radius fractures of this study showed a severe displaced and volar-spiked pattern that might be likely to cause acute ruptures of flexor tendon.…”
