AI Article Synopsis

  • Volar locking plates (VLP) are commonly used for treating distal radius fractures and are deemed the gold standard in surgical treatment.
  • A rare but significant complication from this procedure is the rupture of finger tendons, specifically highlighted by a case involving the flexor digitorum profundus tendon to the index finger after VLP fixation.
  • The tendon rupture was attributed to a mix of mechanical stress from the incorrectly positioned plate and compromised blood circulation in the area, leading to increased pressure in the carpal tunnel.

Article Abstract

Volar locking plates (VLP) have been widely used recently to treat distal radius fractures and are considered the gold standard. One of the most common complications of distal radius fracture surgery is flexor pollicis longus rupture, which may also occur in other tendons. Here, we report a case of isolated rupture of the flexor digitorum profundus to the index finger after VLP fixation of a distal radial fracture. Only a few cases of this have been reported in the literature. In previously reported cases, the cause of tendon rupture was repetitive mechanical stress due to implant protrusion. In our case, the plate was placed too distally; however, soft tissue completely covered the distal part of the plate. There was obvious synovitis within the carpal tunnel; therefore, pressure within the carpal tunnel may have increased. The cause of rupture in our case was thought to be a combination of direct mechanical stress and poor circulation due to inadequate VLP fixation.
