The gap after trapeziectomy: a prospective study

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Musculoskeletal Disorders

Background:

• Basal joint arthritis of the thumb significantly impacts hand function.
• Trapeziectomy is a common surgical intervention for this condition.
• Understanding post-operative changes is crucial for optimizing patient recovery.

Purpose of the Study:

• To evaluate radiological changes, specifically the trapezial gap, after simple trapeziectomy.
• To determine the optimal duration of immobilization following this procedure.
• To assess the long-term stability of the trapezial gap.

Main Methods:

• A cohort of thirteen patients with basal joint thumb arthritis underwent simple trapeziectomy.
• Radiological assessments were performed pre-operatively and at 2, 4, and 12 weeks post-surgery.
• Standardized views were utilized to measure changes in the trapezial gap.

Main Results:

• Radiological assessment revealed collapse of the trapezial gap in patients up to 4 weeks post-surgery.
• No significant changes in the trapezial gap were observed between 4 and 12 weeks.
• This suggests a plateau in the collapse phenomenon after the initial 4-week period.

Conclusions:

• Simple trapeziectomy leads to early post-operative trapezial gap collapse.
• Immobilization beyond 4 weeks does not appear to significantly alter this collapse.
• Current immobilization protocols may be prolonged unnecessarily for this specific radiological finding.
