Summary

Scaphoid nonunion can cause scapholunate gaps, indicating severe ligament injury and instability. This progressive instability leads to early-onset arthritis in the wrist joint.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Radiology

Background:

  • Scaphoid nonunion is a common complication of scaphoid fractures.
  • Scapholunate instability is a significant factor in wrist dysfunction.

Purpose of the Study:

  • To investigate the presence and significance of scapholunate gaps (SLG) in patients with symptomatic scaphoid nonunion.
  • To correlate SLG with ligamentous injury, instability patterns, and the development of arthritis.

Main Methods:

  • Retrospective review of 64 patients with scaphoid nonunion.
  • Roentgenographic analysis of symptomatic, non-surgically treated patients to identify SLG.
  • Assessment of scapholunate angle and association with Dorsal Intercalated Segment Instability (DISI).

Main Results:

  • Ten of 64 patients (15.6%) exhibited scapholunate gaps (SLG).
  • SLG indicated severe ligamentous injury and instability, consistently associated with DISI and increased scapholunate angle.
  • Instability was progressive, leading to early-onset arthritis, particularly in the radioscaphoid and midcarpal joints.

Conclusions:

  • Scapholunate gaps are a radiographic marker of significant ligamentous injury in scaphoid nonunion.
  • SLG and associated instability contribute to the predictable progression of arthritis in scaphoid nonunion.
  • Rotary subluxation of the distal scaphoid fragment is a key factor in terminal wrist arthritis development.
