ICD-10 code
- S63.4. Traumatic rupture of the ligament of the finger at the level of the metacarpophalangeal and interphalangeal joint (s).

What causes damage to the flexor tendons of the fingers flexor fingers?
Closed injuries of the flexor tendons of the fingers flexors arise when lifting heavy flat objects (sheets of metal, glass), open - with various injuries of the palmar surface of the hand.
Symptoms of flexor tendon flexor tendon
Characterized by pain at the time of injury and the subsequent loss of the flexion function of the fingers of the hand, only flexion in the metacarpophalangeal joints was retained. These movements sometimes lead to diagnostic errors. To ensure the integrity of the tendons, you must ask the patient to bend the end phalanx at a fixed mean, and then bend the middle at a fixed base. Such movements are possible only with intact tendons. Open injuries of the tendons are diagnosed on the basis of a violation of the functions of the fingers, as well as visible in the wound of the distal ends of the tendons. The proximal ends of the tendons are biased towards the forearm due to contraction of the muscles.

Surgery
Treatment of damage to the tendons of the flexor flexors of the fingers is only operative. In the early stages, the primary suture of the tendon is produced by one of the methods, with old injuries resorting to the plasty of tendons with autotkani or using various grafts.
The primary tendon suture is most favorable, but it, like the secondary one, has a number of features and presents considerable technical difficulties. Suture material for joining the ends of a severed or crossed tendon should be minimally thin and at the same time very strong. It can be steel or chromium-nickel wire, capron, nylon and other synthetic materials. By the way, they are preferable, because they have inertness unlike metal, silk and (especially) catgut.
Another technical difficulty is the special structure of the tendon, the fibers of which are easily stratified, so that the seam becomes untenable. If the seam grab layers more than a third of its diameter, the blood supply of the tendon is impaired. In addition, gross manipulation of the tendon and its vagina causes the development of an adhesion process that nullifies the functional results of the operation.
A revolutionary coup in tendon surgery was Bennel's proposal (1940) to use removable blocking sutures and their subsequent modifications (Bennel II seam, 1940, SI Degtyarev's seam, 1959, Pugachyov AG seam, 1960). The unloading of the injury site, the minimum number of seams and sutures, the removal of suture material, and the preservation of the tendon circulation have abruptly improved the result of treatment of finger flexor injuries.
