Description

Postoperative dressing device for constrictive tenosynovectomy in children

technical field

The utility model relates to the field of medical equipment, in particular to a postoperative dressing device for constricted tendon sheath release in children.

Background technique

Children's "snap finger", also known as stenosing tenosynovitis or trigger finger, is a common congenital deformity in children. Because the flexor tendon is located at the distal end of the metacarpophalangeal joint, it is narrowed by the narrow fibrocartilaginous lesion of the tendon sheath, which makes the proximal tendon thicken Or it is nodular, making the interphalangeal joints in a flexed position, unable to actively straighten, and causing pain or snapping when passively stretching.

Children with snapping fingers generally do not have symptoms at birth, and it is common for the fingers to flex and cannot be straightened until they are around 6 months to 2 years old. The most common site is the metacarpophalangeal joints of the second and third fingers of the thumb, which can be touched Circular bulge induration, mild tenderness, bouncing sensation when stretching and flexing, while the interphalangeal joints are in a fixed flexion state, and there is a snapping sensation when moving and stretching.

Since congenital tendon sheath stenosis cannot heal by itself, it will easily affect the development of fingers in the future, so it should be treated as soon as possible. Generally, conservative treatment is ineffective, but surgery is effective. It is advisable to make a transverse incision at the transverse crease on the palm side of the metacarpophalangeal joint, and cut the narrow tendon sheath longitudinally so that the enlarged tendon can pass through. Exercise to avoid recurrence of adhesions.

Existing methods all adopt gauze to wrap after the operation, and gauze comes off easily, and gauze is not good to the erect maintenance effect of thumb.
