Using computer graphics to preserve function in resection of malignant melanoma of the foot.

The increasing incidence of malignant melanoma challenges physicians to find innovative ways to preserve function and appearance in affected areas that require partial resection. We carefully planned the resection of a malignant lesion between the third and fourth toes of a 77-year-old man with the aid of computer technology. The subsequent excision of the third, fourth, and fifth digits was executed such that the new metatarsal arc formed would approximate the dimensions of the optimal hyperbola, thereby minimizing gait disturbance.

Use of prostheses and footwear in 110 inner-city partial-foot amputees.

The number of partial-foot amputations performed is increasing, and many recommendations have been made regarding the use of prostheses and footwear designed to prevent higher-level amputations in this population. The present study investigated the use of prostheses and shoe inserts and the types of footwear worn by partial-foot amputees in the inner city to determine whether previous recommendations are being followed as well as whether new prosthetic styles are being used. The study surveyed 110 patients (73 men and 37 women) with a mean age of 58.6 years (range, 21 to 86 years) with partial-foot amputations of all levels. The results showed that about one-half of all patients wore a shoe-insert orthosis. Although 54% wore some form of special footwear to accommodate and protect the residual foot, no patient in this study wore a shoe with a rocker-bottom sole. Only one patient with a transmetatarsal amputation used a brace and only one patient in the entire study wore a modern cosmetic foot prosthesis.

Management of heel pain syndrome with acetic acid iontophoresis.

This study was undertaken to determine the effectiveness of acetic acid iontophoresis in the treatment of heel pain. Thirty-five patients with chronic heel pain were treated with acetic acid iontophoresis over a 4-year period. Ninety-four percent of patients had complete or substantial relief of heel pain after an average of 5.7 sessions of acetic acid iontophoresis over an average period of 2.8 weeks. Heel pain levels were rated from 0 to 10, with 10 representing the most severe pain. Heel pain prior to iontophoresis treatment received an average rating of 7.5; by the end of therapy, the average rating had decreased to 1.8. At an average follow-up time of 27 months, heel pain levels averaged 0.64, indicating continued reduction in heel pain. Ninety-four percent of participants said that they would recommend acetic acid iontophoresis to someone with similar heel pain.

Long-term follow-up of heel spur surgery. A 10-year retrospective study.

A comparative retrospective study of 48 open heel spur surgeries and 20 endoscopic plantar fasciotomies was conducted involving 59 patients over a 10-year period. There was a significant reduction in heel pain at the time of follow-up (average, 3 years) for both groups. Overall, 85% of procedures were associated with patient satisfaction with the results, and patients said that they would recommend heel spur surgery for relief of severe heel pain in 94% of cases. Factors influencing the postoperative outcome, such as duration of preoperative symptoms, extent of conservative care, and obesity, are discussed.

Ankle arthroscopy: follow-up study of 33 ankles--effect of physical therapy and obesity.

A retrospective analysis was conducted of 32 patients (33 ankles) who had undergone surgical ankle arthroscopy for chronic ankle pain that was recalcitrant to conservative treatment. All patients were examined clinically and completed a written questionnaire. Intraoperative ankle arthroscopy showed hypertrophic synovitis, adhesive bands, chondral bands with synovitis, osteophytes, and abnormalities in the talar dome. Results of treatment after an average follow-up time of 1.4 years (range: 0.33 to 12.5 years) showed ankle scores of 15 excellent, 11 good, 5 fair, and 2 poor. Obesity was significantly related to the outcomes of arthroscopy procedures. Obese patients were more likely to be rated as fair or poor, while nonobese patients were significantly more likely to be rated excellent or good. Those patients who received physical therapy postoperatively for one or more months had significantly better ankle ratings than those who did not elect to have physical therapy.

Incurvated nail. Does the phalanx determine nail plate shape?

This study examines the relationship between the shape of the nail plate of the hallux and the base of its distal phalanx. Twenty-three cadaver specimens were examined anatomically for nine variables. These variables represented the following: height and width of the distal phalanx base; height and width of the proximal aspect of the nail plate; distal shape of the nail plate; ratio of the nail plate height and width and structural index of the nail plate. Statistics for the variables are presented using correlation coefficients between nail structural index and bone structural index. The study shows a high and significant correlation between the shape of the proximal aspect of the nail plate and that of the phalangeal base.
