[PDF] Boutonniere deformity | Semantic Scholar (2024)

Boutonniere deformity is a debilitating deformity where the proximal interphalangeal joint of the finger is flexed, and the distal interphalanges joint is hyperextended.

A swan-neck or boutonniere deformity occurs in approximately half of patients with rheumatoid arthritis, and numerous procedures are available for the operative correction of these finger deformities.

The proximal interphalangeal (PIP) joint is a marvel of engineering construction though frequently described as a hinge joint this is a gross oversimplification.

In chronic boutonniere deformity, central slip reconstruction with anchor suture augmentation can be an easily applicable surgical option, which offers fair to excellent outcome in 77% of the cases.

This work presents a case of post-traumatic volar subluxation of the radial lateral band over the proximal phalanx condyle in a patient that resulted in a clinical picture similar to a Grade IIIA trigger finger.

Collagenase has a role in treating the distal interphalangeal joint hyperextension deformity associated with boutonniere deformity in Dupuytren disease and the authors show that collagenase injection led to significant average improvement in joint contracture at all finger joints and significantly increased the arc of motion at the proximal interphalangesal joint and metacarpophalangeal Joint.

The pull-out technique, miniscrew fixation, and spinal needle fixation can produce a good clinical and radiological outcome in the treatment of dorsal lip fracture of the base of the middle phalanx.

The case of a 9-year-old girl who presented to the emergency department with an acute traumatic BD after a fall is presented, which is the first reported case of BD in the pediatric patient population.

This work presents a unique case of painful finger snapping at the PIP joint as a result of longitudinal tear of the central slip, leading to sudden subluxation of one-half of thecentral slip and conjoint lateral band with flexion of the PIA joint.

The "intrinsic-plus" hand, due to contracture of the intrinsic muscle mechanism, can be improved by advancing the intrinsic muscles in the metacarpal region or by sectioning the lateral bands opposite the proximal interphalangeal joints.

The lumbrical muscle, as an extensor of the interphalangeal joint, is demonstrated by a diagram showing its site and length in the various positions of the finger, calculated from the known excursions of the tendons.

Injuries to the tendons which govern the delicate movements of the fingers are all potentially serious as regards subsequent function, and each particular injury demands its own appropriate treatment.

A simple release procedure based on precise anatomy, which redistributes the forces acting on the interphalangeal joints, has been successful in restoring full interphalangesal extension and flexion in a limited number of patients.

In order to assess the validity of the different functions attributed to the lumbrical muscles, their activity has been studied here by (1) electromyography, and (2) electrical stimulation.

The basic biology of tendon tissues is summarized and an update on the latest repair proposals for tendon tears is provided, to summarise the current strategies for enhancing tendon repair.

The natural history of the boutonniere deformity in rheumatoid arthritis is outlined, and a simple method of repair is described, which was successful in a high proportion of cases.
