  • Title: First web space post-burn contracture types: contracture elimination methods.
    Author: Grishkevich VM.
    Journal: Burns; 2011 Mar; 37(2):338-47. PubMed ID: 20851529.
    Abstract:
    First web space adduction contractures are a common consequence of hand burns. Many reconstructive techniques are used and investigation for more effective methods continues. Effective hand reconstruction usually considers anatomy as its foundation. Based on the experience of over 500 web space contracture elimination cases, three anatomical types of thumb adduction contractures were identified: edge, medial and total. Edge contractures (80% of all thumb adduction contractures) are caused by a fold in which only one sheet is scarred, either the palmar or dorsal surface. The contraction is caused by a trapeze-shaped length deficiency of the scar sheet, which has a surface surplus in width. Reconstruction consists of surface deficiency compensation with trapezoid flap prepared from the non-scarred side and skin-fat tissues of the web space. In most cases, the small scar-fat trapezoid flaps should be prepared from the non-scarred side to cover the donor wounds on both sides of the main flap. Medial contractures (10% of thumb adduction contractures) are caused by the fold, both sheets of which are scarred and have trapeze-shaped surface deficiency in length and surplus in width. Both fold sheets are converted into one or several pairs of trapezoid scar-fat flaps by radial incisions. The oppositely located flaps are transposed towards each other. As a result of the counter flaps transposition, the contracture is eliminated; the web space's shape and depth are restored by the use of flaps alone or in combination with skin grafting. The trapeze-flap plasty is very simple and effective with the length gain of up to 100-200%. Neither flap loss nor re-contracture occurs. Total contractures (about 10% of all) have no fold. Reconstruction consists of the creation of the central zone of the first web space depth with the rectangular subdermal pedicle flap; the wounds on both sides of the flap are skin grafted. The flap sustains normal web depth and prevents the contracture recurrence and skin graft shrinkage.
