The authors present an overview of the V-Y plasty technique with a discussion of the basic underlying principles and a description of the surgical technique. The variations available and the direct application of this procedure are discussed with reference to the foot and ankle. Consideration is given for design, location, survival, and postoperative care of the V-Y plasty.
Several types of agents used for intradermal and intralesional injection have been presented along with general discussion of technique and principles of use. We have a great deal of respect for the effectiveness of properly utilized injections in the treatment of various conditions, and we also know that if used improperly, these agents can do more harm than good. For this reason, we caution practitioners to use common sense and to refer to product information and specific sources for additional information before using any of the medications or drugs discussed here. Special attention should be given to systemic absorption and the use of these drugs in infants and children, pregnant and nursing females, and in patients with systemic illness. Each of the agents presented must be evaluated independently and information and experience gathered will aid in the longterm results of their use. We hope this report helps to describe intralesional injections for treatment of some of the more common lesions and that your patients will benefit from this technique.
Intermetatarsal neuromas are caused by trauma secondary to biomechanical factors. A review of the literature concerning intermetatarsal neuromas is presented. The authors discuss foot structure as a possible cause and present data from 292 radiographs that substantiate the proposed theory. They suggest that intermetatarsal neuromas are caused by a combination of factors.
An evaluation of the results of treatment of both fresh and long-standing hypertrophic and keloid scars on the lower extremities using topical SILASTIC Gel Sheeting was performed in 94 patients ranging in age from 11 to 73 years. In the total of 94 patients, there were 80 with true hypertrophic scars. Of this group, 74 patients (92.5%) were greatly improved with treatment, five patients (6.25%) were somewhat improved, and one patient (1.25%) was not improved. The remaining 14 patients in the study had true keloid scars, and their results were poorer with five patients (35.7%) greatly improved, five patients (35.7%) somewhat improved, and four patients (28.6%) showing no improvement. When all patients were totalled together, there were 79 patients (84%) greatly improved, 10 patients (11%) somewhat improved, and only five patients (5%) with no improvements. Overall, the success rate (somewhat improved to greatly improved) for the treatment of hypertrophic and keloid scars is high (95%).
