Imaging of digital neuromas.

In this case presentation, an incision was made on the nonweightbearing surface of the hallux directly over the mass in question, just long enough to allow for the isolation of the entire mass. This permitted easier identification of the mass and enabled dissection of the abnormal tissue and excision of only the tumor with a minimum of tissue trauma. Healing was uneventful and expedient largely because of the reduced tissue handling. Prior to the advent of magnetic resonance imaging, this type of preoperative detailed surgical mapping would not have been possible. Continuing improvements in magnetic resonance imaging hold great and increasing promise.

Chondromyxoid fibroma.

Chondromyxoid fibroma is a rare benign tumor derived from cartilage. The classic site of involvement is usually the metaphyseal ends of the long tubular bones, such as the tibia. The majority of these tumors are seen in the lower extremities during the second and third decades of life. Local recurrence of the tumor in bone is not uncommon, while soft tissue recurrence is less frequent. Most younger patients and those with recurrent tumors tend to have the mucinous type. This case is somewhat classic in nature. The tumor was originally seen in the second decade of life and was of the mucinoid type. Bone grafting was necessary because of the size and location of the tumor.

Digital chondroma.

Digital or extraskeletal chondromas are rare tumors. Slow growing in nature, they rarely exceed 3 cm. in diameter. Surgical intervention is necessary for diagnosis and elimination of the problem.

Benign leiomyoma of the foot: a case report.

This article describes a benign tumor of smooth muscle cells, its clinical findings, and its differential diagnosis. Surgical intervention is considered to be the only definitive therapy.

The efficacy of laser surgery for verruca plantaris: report of a study.

Many therapeutic modalities are available to eradicate plantar verrucae. Lately, lasers have gained a great deal of notoriety in the treatment of verrucae. In this study, we chose to evaluate the success of using one laser treatment for full eradication of verrucae. The results indicated that the greatest success rate occurred with solitary lesions. Other studies of methods of verrucae treatment yielded similar results to those of the laser, with cryotherapy achieving the highest success rate. However, the higher rate was based on an average of two treatments, whereas this study obtained similar results with just one. The laser also has the advantages of minimal postoperative pain, minimal healing time, and less damage to perilesional tissue. These advantages make the laser a viable option in the treatment of verrucae plantaris.

Chronic osteomyelitis associated with monofilament wire fixation.

Infections following osteotomy and internal fixation must be treated aggressively. The plan of treatment should include the following: 1) continued immobilization of the part during healing, 2) removal of any internal fixation device after the osteotomy site is stable, 3) debridement of necrotic debris, and 4) use of an appropriate antibiotic over a sufficient time period (including a few weeks after removal of an internal fixation device). A report was made of a case of chronic osteomyelitis that may have resulted from undertreatment of a postoperative infection.

Subtleties of Lisfranc fracture-dislocations.

Tarsometatarsal (Lisfranc) fracture-dislocations can be very difficult to recognize radiographically. The evaluation of the Lisfranc joint can be simplified by meticulously studying the alignment of the metatarsal bases with their corresponding tarsal bones. The usefulness of this observation has been confirmed by: anatomic descriptions, biomechanical analysis, and clinical foot radiographs. Subtle abnormalities identified at the Lisfranc joint using this observation included: metatarsal subluxations identified only on a single projection, associated tarsal subluxations and dislocations, irreducible metatarsal subluxations after closed manipulation, and recurrent metatarsal subluxations after reduction.

Plantar basal cell carcinoma: a case report.

Basal cell carcinoma, the most common type of skin cancer, is usually found in Caucasians between 50 and 70 years of age who are frequently exposed to sunlight or x-irradiation. They are rarely found in blacks and are seldom seen on the palmar or plantar surfaces. Dr. Galinski reports on a black male with a basal cell carcinoma on the planter surface of his right foot. Squamous cell carcinoma, keratoacanthoma, seborrheic keratosis, and sebaceous hyperplasia resemble basal cell carcinoma and must be considered in a differential diagnosis. Unlike most tumors, basal cell carcinomas spread by direct extension.
