Compression screw fixation in proximal first metatarsal osteotomies for metatarsus primus varus: initial observations.

Many methods of fixation have been used after proximal abductory metatarsal osteotomies for the correction of metatarsus primus varus. The methods include external immobilization and the application of devices such as stainless steel wire, Kirschner wires, staples, and compression plates. We have combined external immobilization with compression screw fixation across the osteotomy site. Two different types of screws were used: 1) an AO screw 3.6 mm. wide and 26 to 28 mm. long and 2) a standard Woodruff screw 3.5 mm. wide and 31.8 to 44.4 mm long. Twenty-two procedures were reviewed. When we compared the results, we found the AO screw to be superior in the degree of rigid fixation which it provides, as judged by the extent of postoperative callus formation.

Mechanism and reconstruction of pes cavus.

Many important factors are involved in the surgical treatment of pes cavus. Among these factors are the location of the deformity--frontal, sagittal, or transverse planes--and whether there is an associated muscle weakness. Biomechanical analysis will help to determine whether the cavus foot is rigid or nonrigid and how it functions. Neurologic and radiologic tests must also be used to determine the type of operative procedure required for correction of the deformity.

The use of ultrasonography for the detection of retained wooden foreign bodies in the foot.

The efficacy of ultrasonography for the detection of wooden foreign bodies in the foot was analyzed retrospectively. Twenty patients underwent real-time, high-resolution ultrasound studies (7.5 or 10 MHz, linear array transducers) to rule out the presence of a wooden foreign body in their feet. Ten out of the 20 patients had positive ultrasound findings for a wooden foreign body. With the aid of the ultrasound study and preoperative markings, the subsequent mean surgical time was 20.8 minutes, with a 100% retrieval rate of the foreign body. Ultrasound was found to be 100% sensitive in the detection of wooden foreign bodies in the soft tissues of the foot. Ultrasonography should be considered an important diagnostic modality in the foot and ankle surgeon's armamentarium for the detection of retained wooden foreign bodies.

Subcutaneous phaeohypomycosis caused by Scytalidium dimidiatum in the foot of an immunosuppressed host.

The authors present a case report of a subcutaneous phaeohypomycosis of the foot in an immuno-suppressed patient. The lesion was caused by Scytalidium dimidiatum, a dematiaceous fungus, which has only been reported to cause three previous similar lesions. To our knowledge, this is the first reported case of this fungus causing a deep-seated mycoses in the United States. A review of the literature concerning this organism is also presented.

Retrospective analysis of surgical treatment of hallux rigidus/limitus: clinical and radiographic follow-up of hinged, silastic implant arthroplasty and cheilectomy.

Many authors have hypothesized on the etiology of hallux limitus and have proposed grading systems for classifying the degree of first metatarsophalangeal joint derangement and dysfunction. Several opinions exist regarding surgical treatment, should a patient fail with conservative therapy. Hinged, Silastic implant arthroplasty and cheilectomy account for a significant proportion of procedures accomplished. However, little follow-up documents and critically analyzes the long-term results of these procedures. This study analyzes, retrospectively, the results of these procedures with a minimum follow-up of 46 months. Hinged, Silastic implant arthroplasty appears to be a safe, technically easy, efficacious procedure in the grade II to III lesion in patients of 60 years or older, in whom an active life-style is desired. Cheilectomy appears to be indicated in the patient with a classic grade I lesion, while its use in grade II lesions, especially in the presence of sesamoid disease, requires further investigation.

Retrospective analysis of intermetatarsal neuroma excision with preservation of the transverse metatarsal ligament.

The authors present a retrospective analysis of intermetatarsal neuroma excision with preservation of the transverse metatarsal ligament. They reviewed a series of 43 patients who had undergone a total of 59 such surgical resections. No other surgical procedures were performed on the foot. The patients included 36 women, and 7 men. Follow-up ranged from 1 year and 5 months to 6 years and 3 months with an average of 4 years and 3 months. Fifty-one of the neuromas removed were in the third interspace, three in the second interspace, and five in the fourth interspace. The surgical excision was performed in standard fashion except for the major modification of preservation of the transverse metatarsal ligament. There were 47 excellent or good results and, thus, the overall success rate was 79%. Seven patients had fair results and five had poor results. The results compare favorably with those reported by other authors who advocate transecting the transverse metatarsal ligament. The authors conclude that their approach to surgical excision of intermetatarsal neuromas is valid while preservation of the normal ligamentous anatomy is maintained.
