Aeromonas hydrophilia: a rare and potentially life-threatening pathogen to humans.

The authors discuss the diagnosis, symptoms, and treatment of infections resulting from Aeromonas hydrophilia, and uncommon pathogen that is being reported with increasing frequency and may be serious to man. They present the case history of a 38-year-old male and emphasize the importance of prompt and proper treatment.

Asymmetric "V" osteotomy: a predictable surgical approach for chronic central metatarsalgia.

Chronic metatarsalgia is a condition found through the years to present many treatment difficulties. These difficulties began with a lack of understanding, not only concerning the etiologic nature of this condition, but failure to appreciate the surgical treatment ramifications inherent to alterations in the metatarsal parabola. These failures have subsequently led to lesions under the adjacent metatarsal heads, stress fractures, flail toes, and other postoperative pathology. This often leads to further surgical intervention or accommodative modifications. The authors offer an analysis of surgical approaches to this problem and present a more predictable surgical technique to enhance the metatarsal parabola, while decreasing either excessive plantarflexion of a particular metatarsal or set of metatarsals. To date the senior author (E.L.) has performed the asymmetric "V" osteotomy on 30 patients for a total of 40 metatarsals. After a 12- to 18-month postoperative period, there have been no significant complications, including recurrences, transfer lesions, excessive secondary bone callous, malunions, or adjacent metatarsalgia. Delayed union with secondary bone callous has developed in two instances. The authors introduce an innovative surgical approach to structural metatarsal abnormalities as a distinct advantage to other previously described osteotomies with greater predictability, better anatomic reduction, primary bone healing, and faster return to normal activities.

Autogenous free dermal fat grafts in the surgical approach to plantar fibromatosis.

Plantar fibromatosis is a benign disorder of the foot in which there is fibrous tissue infiltration of the plantar aponeurosis and in some cases the overlying skin. Treatment is indicated for pain and functional gait disturbance. Even with wide fascial resection, recurrence with spreading, scarring, and continued discomfort can be a frustrating and difficult problem. Various techniques to lessen recurrence have included split-thickness skin grafting and Marlex mesh placement. However, these procedures have documented problems, including recurrence, foreign-body reaction, scarring, and inadequate soft-tissue coverage. The authors introduce dermal fat grafting following primary excision as a means to minimize recurrence while maintaining the anatomic architecture of the foot and preserving a soft, supple weightbearing surface with minimal scar tissue formation.

Unicameral bone cysts: treatment with methylprednisone acetate injections.

Unicameral bone cysts have been treated by a variety of methods including nonoperative treatment, bone packing, and methylprednisone acetate injection. This article reviews the methods of treatment and classification of unicameral bone cysts. Three calcaneal unicameral bone cysts were injected with methylprednisone acetate and were followed for 8 to 32 months. Two unicameral bone cysts were unresponsive to methylprednisone acetate and were classified as "persistent." One unicameral bone cyst was moderately responsive and was classified as "incompletely resolved."

Digital "V" arthrodesis.

Numerous procedures have been proposed through the years for the treatment of digital hammertoes and other related structural deformities. Experience has determined that many of these procedures are structurally incorrect and result in secondary deformity, which are often worse than the pathology initially addressed. Phalangeal base resections were found to destroy the structural stability provided by the intrinsic musculature. Phalangeal head resections make the toe impressionable to the extrinsic forces of the adjacent toes often leading to structural mal-alignment, or additional contracture. Similarly, indiscriminate tendon lengthenings have led to flail toes and a lack of purchase and propulsion. The advent of proximal interphalangeal joint arthrodesis demonstrated that structural stability and propulsion could be maintained while enhancing alignment. The "V" arthrodesis, as introduced by the authors, provides an alternative surgical approach to digital fusions. This approach is technically less difficult compared with a peg-in-hole fusion and provides enhanced stability when compared with an end-to-end arthrodesis. The preliminary results of this procedure appear to be most promising and are provided to the readership for review and examination.
