Description

Finger splint for treating mallet-shaped finger

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a finger splint for treating mallet finger.

Background

Mallet-like fingers are common diseases in hand surgery and are divided into fracture at the terminal dead point of tendon of extensor carpi tendineus of tendinous mallet-like fingers and avulsion fracture at the terminal dead point of extensor carpi tendineus of bony mallet-like fingers. The conservative treatment of the dorsal avulsion bone block of the end phalanx basement which is less than 1/3 of the joint surface can obtain satisfactory curative effect. Splinting is often used clinically, but the prognosis of some patients is poor, and mallet fingers relapse, so that the surgical treatment is performed. The reason for this is that the reduction of the bone fragments is not in place due to the incomplete extension of the distal interphalangeal joint or too small an over-extension angle. The Stank splint, micks splint and aluminum bar splint which are commonly used clinically are structurally straight, but the distal interphalangeal joint is not completely straightened due to the poor fixation or loose fixation of the patient's distal phalanx. Thus, one of the major points in the use of splints to treat mallet fingers is how to cause slight hyperextension of the distal interphalangeal joint.
