Carpal instability non-dissociative (CIND) in wrist pain patients yielded disappointing results, with no significant difference between surgical and non-surgical treatments. Ulna-minus CIND patients undergoing osteotomy showed the best outcomes.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Wrist Biomechanics

Background:

  • Carpal instability non-dissociative (CIND) presents with wrist pain and weakness.
  • Intrinsic interosseous ligaments are intact in CIND patients.
  • Proximal carpal row instability is the hallmark of CIND.

Purpose of the Study:

  • To evaluate treatment outcomes for carpal instability non-dissociative (CIND).
  • To identify factors influencing treatment success in CIND patients.

Main Methods:

  • Retrospective study of 45 CIND patients with a minimum 18-month follow-up.
  • Analysis of non-operative (n=7) and operative (n=38) treatment groups.
  • Operative treatments included soft tissue reconstruction, joint levelling osteotomy, and mid-carpal fusion.

Main Results:

  • Overall good/excellent results were 56%, with no significant difference between treatment groups.
  • Ulna-minus CIND patients treated with joint levelling osteotomy achieved 83% good/excellent results.
  • Treatment results for CIND are unpredictable due to difficulties in pinpointing pathology.

Conclusions:

  • Current treatments for CIND have unpredictable outcomes.
  • Improved understanding of CIND pathomechanics is needed for more specific and effective treatments.
  • Targeted interventions, particularly osteotomy for ulna-minus CIND, show promise.
