Scaphotrapeziotrapezoid arthrodesis for arthritis

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Wrist Biomechanics

Background:

• Scaphotrapeziotrapezoid (STT) arthritis, rotary subluxation of the scaphoid, and Kienbock disease are common wrist conditions.
• Surgical intervention is often required for refractory cases.
• STT fusion is one surgical option for these indications.

Purpose of the Study:

• To review the literature on scaphotrapeziotrapezoid (STT) fusion outcomes for specific wrist pathologies.
• To discuss the advantages, disadvantages, and alternatives to STT fusion.
• To present the authors' surgical technique and results for STT fusion.

Main Methods:

• Literature review of STT fusion for STT arthritis, rotary subluxation of the scaphoid, and Kienbock disease.
• Analysis of reported outcomes, complications, and alternative treatments.
• Description of the authors' specific surgical technique and retrospective case review.

Main Results:

• Published literature demonstrates variable outcomes for STT fusion depending on the indication.
• Advantages include pain relief and stability, while disadvantages may involve stiffness and nonunion.
• The authors' technique yielded specific results (details to be elaborated in the full text).

Conclusions:

• STT fusion is a potentially effective procedure for select patients with STT arthritis, scaphoid instability, or Kienbock disease.
• Careful patient selection and surgical technique are crucial for optimal outcomes.
• The procedure offers a viable alternative to other reconstructive or salvage options in specific clinical scenarios.
