Habitual extensor tendon dislocation.

Area of Science:

• Rheumatology
• Orthopedic Surgery
• Hand Surgery

Background:

• Rheumatoid hand deformities frequently involve tendon dislocations.
• Habitual tendon dislocation is a rare manifestation in rheumatoid arthritis patients.
• Seronegative rheumatoid arthritis patients can present with unique challenges.

Observation:

• A case series of five seronegative rheumatoid arthritis patients with habitual extensor tendon dislocation was studied.
• The patients presented with a specific pattern of deformity.
• Clinical observations guided the investigation into causative factors.

Findings:

• The study discusses the etiology of habitual extensor tendon dislocation in the rheumatoid hand.
• Treatment options are evaluated based on existing literature and case observations.
• An extensor loop operation is identified as a recommended surgical intervention.

Implications:

• The findings suggest a specific surgical approach for managing rare tendon dislocations in rheumatoid hands.
• Understanding the causation can lead to improved treatment strategies.
• This research contributes to the management of complex rheumatoid hand deformities.
