First metatarsophalangeal joint implant as a salvage procedure.

First metatarsophalangeal joint implants are used to correct deformity, to restore or improve motion, and to relieve pain. The authors report on a patient with pain in the first metatarsophalangeal joint that was not relieved by multiple first metatarsophalangeal joint surgical procedures. A two-component first metatarsophalangeal joint titanium implant was successfully used as a salvage procedure to relieve pain and restore foot function following a failed first metatarsophalangeal joint fusion.

Ancrod (Arvin) as an alternative to heparin anticoagulation for cardiopulmonary bypass.

Heparin is the anticoagulant used during cardiopulmonary bypass (CPB). Both the use of heparin and the reversal of its effect with protamine have well-documented complications. Ancrod is a defibrinogenating enzyme that has been used as an anticoagulant in humans, but its use as an anticoagulant for CPB has been limited to studies in animals. Twenty patients for elective aortocoronary bypass surgery were anticoagulated by means of an intravenous infusion of ancrod pre-operatively. Target plasma fibrinogen concentrations of 0.40-0.80 g/l were achieved within 13.3 +/- 2.5 h using an average dose of ancrod of 1.65 +/- 0.55 U/g. All perfusions were without incident. Postoperative blood loss (2286 +/- 1311 cc) was compared to that of 20 matched controls (1737 +/- 973 cc), as was blood product use; 4.1 +/- 2.1 U of packed cells versus 2.5 +/- 2.3 U (P less than 0.05) and 5.6 +/- 3.1 U of plasma versus 2.6 +/- 2.9 U (P less than 0.05) in the ancrod and heparin-treated groups, respectively. There were no differences in the postoperative courses or recovery periods of the ancrod-treated and control patients. This study confirms the efficacy and feasibility of ancrod as an alternative form of anticoagulation for CPB.

Angioleiomyoma.

Angioleiomyoma is a benign tumor that occurs rarely, but it must be considered in the differential diagnosis in patients who have a painful subcutaneous nodule on the lower extremity. The treatment of choice in all cases is surgical excision.

Osteomyelitis of the foot in diabetic patients: evaluation with magnetic resonance imaging.

Magnetic resonance (MR) imaging examination was performed with a 1.5-Tesla superconducting magnet on a diabetic patient's right foot that had extensive deformities due to previous surgery, infection, and neuropathy. The purpose of the examination was to help identify areas of active infection in preparation for surgical debridement. This manuscript reviews current concepts on the use of radionucleotide scanning and computed tomography (CT) as compared to MR imaging when used to assist in the diagnosis of osteomyelitis in the diabetic foot. MR imaging was found to be useful in identifying areas of active bone infection in the presence of underlying osseous pathology when radiographic images and radionucleotide scans were unreliable.

Prophylactic antibiotic usage in podiatric implant surgery of the first metatarsophalangeal joint.

All first metatarsophalangeal joint implants used at Sheridan Park Hospital from 1979 through 1984 were evaluated for postoperative infection and subsequent implant removal. Thirteen (1.3%) of 929 implants used were removed due to infection. Antibiotic prophylaxis was not determined to be necessary to avoid this complication. However, in all cases in which prophylaxis was used, no infection occurred.

Reverse Austin osteotomy for correction of acquired static hallux adductus.

Hallux adductus, a horizontal plane deformity, often has an iatrogenic etiology especially as a complication of hallux abducto valgus surgery. A case at Sheridan Park Hospital is described in which the patient developed a steadily worsening static hallux adductus following foot surgery. She underwent further corrective procedures for the hallux adductus 11/2 years later. The authors conclude that if a mild static hallux adductus is observed in conjunction with bunionectomy or other surgery, it should be corrected at that time rather than some years later.

Topical hemostatic agents to reduce bleeding from cancellous bone surfaces: a comparison of Gelfoam paste and bone wax.

This article reviews the history of topical bone hemostatic agents, listing advantages and disadvantages of the more commonly used agents. Gelfoam paste and bone wax were chosen to study the effects that bone hemostatic agents have on the occurrence and severity of postoperative edema and pain. The authors discovered 80% of the patients utilizing bone wax, and 91% of the patients receiving Gelfoam paste, had markedly decreased amounts of immediate postoperative edema. Furthermore, 90% of the patients treated with bone wax, and 75% of the patients treated with Gelfoam paste, reported less postoperative pain than anticipated with the surgical procedure performed.

The use of naproxen in controlling postoperative pain in podiatric surgery.

The study was conducted with 110 patients admitted to Sheridan Park Hospital to determine the efficacy of the nonsteroidal anti-inflammatory drug, naproxen, in relieving postoperative pain. Aspirin, as well as compounds classified as nonsteroidal, anti-inflammatory drugs (NSAID), such as naproxen, are known to inhibit synthesis of certain prostaglandins that are involved in the inflammation process. This is the cause of a significant percentage of postoperative pain.

Control of postoperative pain in foot surgery using a combination of anesthetic and steroid for local infiltration.

The authors examine a technique that is performed for control of postoperative pain. Sixty-eight patients were evaluated who had received a combination of Marcaine with no epinephrine, plus Hexadrol, at the surgical site immediately postoperatively. It was found that 65% did not require any form of analgesia within the first 4 hours postsurgically; 44% the first 8 hours, and 28% the first 12 hours. Sixteen percent of the patients required no form of analgesia during their entire hospital stay.

A new instrumentation for heel spur resection.

Numerous procedures are available for resecting an inferior calcaneal exostosis (heel spur) when conservative management of the condition fails. A study was conducted with Sheridan Park Hospital patients by using the Kazanjian nasal forceps for spur removal. This procedure minimizes soft tissue destruction, bone pain, and iatrogenic calcaneal fractures.

Bacteriology of diabetic foot ulcers.

Diabetic foot ulcerations exhibit a wide range of the bacterial spectrum. A long-standing question is whether any particular bacterium or class of bacteria is responsible for the more involved ulcers. A review of such cases at Sheridan Park Hospital reveals that there may be factors other than bacterial type that may account for the virulence of diabetic ulcers. Multifactorial causes host a vital role in this common, but potentially serious, podiatric problem.

Tibial sesamoid planing procedure: an appraisal of 26 feet.

The authors present their findings upon evaluation of 26 feet that had undergone a tibial sesamoid planing procedure. A preoperative method of radiographic evaluation is also presented. The subjective success rate was determined to be 88.8%, whereas the objective success rate was 76.9%, and a successful procedure was performed on feet with a first metatarsal declination angle not exceeding 8 degrees. It was also determined that the apparent postoperative changes in the hallux abductus and intermetatarsal angles were 0.73 degrees and 0.6 degrees, respectively. The authors believe this procedure does not significantly alter the biomechanics of the first metatarsophalangeal joint postoperatively.
