[Stenosing tenovaginitis -- is injection therapy beneficial?]

Area of Science:

• Orthopedics
• Rheumatology
• Pharmacology

Background:

• Stenosing tenovaginitis (ST) is a common condition affecting tendons, often leading to pain and limited mobility.
• Injection therapy is a potential treatment modality for ST, but its long-term efficacy and patient outcomes require further investigation.

Purpose of the Study:

• To evaluate the effectiveness of injection therapy for stenosing tenovaginitis (ST).
• To assess symptom relief, complaint frequency, patient satisfaction, and relapse rates following injection therapy for ST.

Main Methods:

• Fifty-five patients with ST received injections of triamcinolone and mepivacain hydrochloride.
• Outcomes including symptom relief, complaint frequency, subjective assessment, and recurrence were monitored for five years.
• Patients were categorized into groups based on treatment outcome: good outcome, poor outcome, or subsequent surgery.

Main Results:

• The middle and ring fingers were most frequently affected by ST.
• Nearly half of the patients (49%) achieved long-term symptom relief, while 66% experienced short-term relief.
• Injection therapy failure was more prevalent in men, younger patients, and those with diabetes; conversely, better outcomes were observed in women, older patients, and those with rheumatism. No complications were reported.

Conclusions:

• Injection therapy serves as a justifiable alternative to surgery for patients with stenosing tenovaginitis.
• Approximately half of the patients reported positive long-term outcomes and satisfaction with injection therapy.
• Women, older patients, and individuals with rheumatism showed particularly favorable responses to the treatment.
