First Carpo-metacarpal Joint Arthritis: Interpositional Arthroplasty using Trapezium

Area of Science:

• Orthopedic surgery
• Rheumatology
• Hand surgery

Background:

• Basal joint thumb arthritis (first carpometacarpal arthritis) is a prevalent and disabling condition, particularly affecting women.
• Diagnosis is typically achieved through clinical history and physical examination.
• Current treatments, both conservative and surgical, have variable success rates.

Observation:

• A novel surgical technique was employed for a middle-aged female patient diagnosed with first carpometacarpal joint arthritis.
• The procedure involved excising the trapezium, processing it, and reinserting it within a sponge covering into the created void.
• The patient's condition was monitored for one year post-procedure.

Findings:

• The patient experienced complete pain relief following the surgical intervention.
• Full range of thumb motion and restored strength were observed at the one-year follow-up.
• This innovative reconstructive approach demonstrated significant positive outcomes.

Implications:

• This technique presents a promising alternative for managing advanced basal joint thumb arthritis.
• Further research and clinical trials are warranted to validate the long-term efficacy and generalizability of this procedure.
• The findings suggest potential for improved patient outcomes and quality of life in individuals suffering from thumb arthritis.
