Abstract:
Background: Long-standing trigger finger can lead to proximal interphalangeal (PIP) joint flexion contracture. In the present study, we present the clinical outcome of percutaneous release with finger splinting for trigger finger with PIP joint flexion contracture prospectively. Methods: We compared outcomes in patients with trigger fingers combined with proximal interphalangeal joint flexion contracture treated by percutaneous release therapy regimen alone (group I) or percutaneous trigger finger release combined with finger splint (group II) during January 2011 and May 2016 with 6 months follow up. Results: Sixty-five patients were randomly allocated to group I (35 patients) or group II (30 patients). Symptoms of locking sensation and pain over the A1 pulley were improved in all patients. The patients in group II showed significantly greater improvements in the flexion contracture angles of proximal interphalangeal joint at post-operative 3 months later (group I, 9.4° ± 4.1°; group II, 27.8° ± 4.6°) and at 6 months later (group I, 15.1° ± 5.2°; group II, 35.7° ± 5.3°) relative to group I. In group II, 25 fingers achieved near full extension (< 10° contracture) after 6 months. Conclusions: Percutaneous release combined with finger splint is regarded as a useful therapy to speed recovery of trigger finger with proximal interphalangeal joint flexion contracture.

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
