Blatt's capsulodesis for chronic scapholunate instability

Area of Science:

• Orthopedic Surgery
• Hand and Wrist Surgery
• Sports Medicine

Background:

• Scapholunate instability is a common cause of wrist pain and dysfunction.
• Surgical intervention is often necessary for predynamic and dynamic instability.
• Blatt's capsulodesis is a recognized technique for wrist stabilization.

Purpose of the Study:

• To evaluate the clinical and radiological outcomes of scapholunate interosseous ligament repair combined with Blatt's capsulodesis.
• To assess the effectiveness of this combined procedure in patients with scapholunate instability.

Main Methods:

• Retrospective review of 19 patients undergoing the combined procedure between 1994 and 1999.
• Diagnosis confirmed via clinical, radiographic, and arthroscopic assessments.
• Follow-up included clinical evaluation and radiological measurements at a mean of 22 months.

Main Results:

• 13 of 15 patients reported good or excellent clinical results.
• Significant improvements in pain relief (VAS scores), grip strength, wrist extension, and ulnar deviation.
• No significant changes in scapholunate gap or angle post-surgery.
• 13 patients would recommend the procedure.

Conclusions:

• The combined scapholunate ligament repair and Blatt's capsulodesis procedure demonstrates encouraging outcomes for predynamic and dynamic scapholunate instability.
• This surgical technique can restore function and alleviate pain in low-demand wrist patients.
• Further research with larger cohorts and longer follow-up is recommended for robust evidence.
