METHOD FOR PRESERVING TENDON CANAL OF FINGER IN SUPPURATIVE COMPLICATION AT FIRST STAGE OF TENDOPLASTY Russian patent published in 2014 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: silicone tendon prosthesis is removed from an incised fingertip if observing a pus formation around. A broad-spectrum antibiotic is prescribed. An exposed tendon canal is used for regular rinsing with a disinfectant solution, and drainage. Once the inflammation has been completely managed, the finger canal is dilated from three approaches: from the fingertip, from the middle of the finger, and from the middle of a palm that is ensured by inserting a dilator as far as it can go into the soft tissues at the level of a proximal phalanx. An oblique incision of the skin and soft tissues of the finger are made along the palm surface of the finger to expose the tendon canal and to find a dilator tip. With the dilator inside the tendon canal of the finger, the canal is dilated actively with using the reciprocating dilator from the fingertip to the middle of the proximal phalanx; then the dilator is removed. A third incision is made of the palm, and once a tendon canal opening is found on the finger base, the dilator is inserted therein in the opposite direction from the palm to the fingertip. The dilator is brought up to the middle of the finger until the dilator tip is seen in the pre-formed oblique insicion. The canal is dilated with using the reciprocating dilator; the sutured ends of palm flexors are mobilised. The superficial ends of the flexors are brought onto the skin; a defect of a deep finger flexor is replaced with a thin autograft.

EFFECT: method enables relieving the infection, conducting early re-canalisation and tendoplasty.
