Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...

Summary

Giant cell tumour (GCT) of the distal ulna requires aggressive resection. Reconstruction using fibular and palmaris longus grafts offers excellent functional outcomes for young, active patients, preserving wrist stability and strength.

Area of Science:

  • Orthopedic Surgery
  • Oncology
  • Musculoskeletal Tumors

Background:

  • Giant cell tumour (GCT) is a rare, locally aggressive benign bone tumor.
  • Distal ulna GCT necessitates wide en-bloc resection, potentially leading to wrist instability and functional deficits.
  • Current treatment may compromise wrist function, especially in young, high-demand individuals.

Purpose of the Study:

  • To evaluate a reconstructive surgical technique for distal ulna GCT in young patients.
  • To assess the functional outcomes of distal ulna and distal radioulnar joint reconstruction.
  • To confirm the efficacy of this approach in restoring wrist stability and grip strength.

Main Methods:

  • En-bloc resection of the distal ulna affected by GCT.
  • Reconstruction of the distal ulna using an autologous free fibular graft.
  • Stabilization of the distal radioulnar joint with an autologous palmaris longus tendon graft.
  • Evaluation of functional results in three young patients.

Main Results:

  • The presented surgical technique achieved satisfactory functional results in all three young patients.
  • Reconstruction effectively addressed wrist instability and grip strength deficits post-resection.
  • The procedure maintained or improved wrist function in active individuals.

Conclusions:

  • Reconstruction of the distal ulna and distal radioulnar joint is a viable and effective treatment for GCT in young, active patients.
  • This approach leads to satisfactory functional outcomes, preserving wrist stability and strength.
  • The technique offers a promising solution for managing distal ulna GCT while optimizing functional recovery.
