Fractures: Bone Repair01:27

Fractures: Bone Repair

2.8K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bones of the Upper Limb: Radius

1.9K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Summary
This summary is machine-generated.

Older volar locking plates (VLPs) with Soong grade 2 increase long-term risk for flexor pollicis longus (FPL) tendon rupture after distal radius fracture (DRF) fixation. Reconstruction with palmaris longus (PL) grafts yields fair to good outcomes.

Area of Science:

  • Orthopedic surgery
  • Hand surgery
  • Trauma surgery

Background:

  • Volar locking plate (VLP) fixation is standard for distal radius fractures (DRFs).
  • Attritional flexor tendon rupture is a known, albeit rare, complication of VLP fixation.
  • No established consensus exists for preventing this complication.

Purpose of the Study:

  • To investigate the long-term risk of flexor tendon rupture following VLP fixation for DRFs.
  • To characterize the outcomes of flexor tendon rupture reconstruction.

Main Methods:

  • Retrospective single-center review (2016-2021) of patients with attritional flexor tendon rupture post-VLP fixation.
  • Collected data included patient demographics, DRF details (AO classification, Soong grading), and tendon reconstruction methods.
  • Evaluated outcomes using thumb interphalangeal joint (IPJ) motion and Kapandji score.

Main Results:

  • Five patients experienced attritional flexor pollicis longus (FPL) ruptures.
  • Median time from VLP fixation to rupture was 7 years (range: 3-14 years).
  • Four ruptures were reconstructed with palmaris longus (PL) tendon grafts, achieving a median IPJ motion of 48 degrees and Kapandji score of 9/10.

Conclusions:

  • Older VLP designs, particularly those with Soong grade 2, present a sustained risk for attritional FPL rupture.
  • Palmaris longus tendon grafting is an effective method for reconstructing FPL ruptures, yielding satisfactory functional results.
