PMMA bead versus parenteral treatment of Staphylococcus aureus osteomyelitis.

A. rabbit model of Staphylococcus aureus osteomyelitis was used to compare 3 weeks of clindamycin-impregnated polymethylmethacralate (PMMA) bead treatment with 3 weeks of gentamicin-impregnated polymethylmethacralate bead treatment, 4 weeks of parenteral clindamycin treatment, and surgical debridement without any antibiotic treatment. The animals were weighed throughout the course of the experiment and cortical bone and marrow flush specimens were obtained for bacterial culture at the end of therapy. The cortical specimens were bacteria free in 100% (6/6) of the animals receiving parenteral clindamycin, 83% (5/6) of the animals in the clindamycin PMMA group and, none of the animals in the gentamicin PMMA group. The marrow flush specimens were bacteria free in 83% (5/6) of the animals in the parenteral clindamycin group, 67% (4/6) of the animals in the clindamycin PMMA group, and 40% (2/5) of the animals in the gentamicin PMMA group. While these findings are preliminary and further studies with larger numbers of animals are needed, the authors suggest that when PMMA bead therapy is being contemplated, serious consideration should be given to replacing gentamicin with clindamycin in treatment of gram-positive osteomyelitis. Furthermore, incorporation of clindamycin with gentamicin (or tobramycin) should be considered when treating mixed gram-positive and gram-negative osteomyelitis.

Sesamoid complex disorders.

Disorders of the hallux sesamoids and associated soft-tissue structures are commonly seen. With a differential diagnosis consisting of no fewer than 30 conditions, establishing an accurate diagnosis can be challenging but is important to appropriate treatment implementation. An understanding of first metatarsophalangeal joint anatomy, function, and current diagnostic technology aids the practitioner in the diagnosis and successful treatment of these often overlooked and anecdotally managed disorders.

Magnetic resonance imaging of traumatized ligaments of the ankle.

The clinical examination of acute soft tissue injuries of the ankle does not necessarily help to delineate the extent of injury. Ankle stress radiographs and arthrography have been applied for a more accurate assessment of the actual degree of ligamentous damage. However, these studies do not define the level of the ligament tear of the relationship of torn ligament ends to one another. This information would seem to be valuable in deciding whether a conservative or surgical approach would be advisable. The following study evaluated the possible role of magnetic resonance imaging in assessment of these injuries. The ability to assess ankle ligaments was first undertaken. Once this was successfully performed, magnetic resonance imaging was used to assess the degree of ligament damage in 15 patients. Magnetic resonance imaging proved to be comparable to arthrography. It also provided additional valuable information.

CCPM and podiatric medical education. Preparing for the 21st century.

There are many changes on the horizon that will affect how we teach the future practitioners of podiatric medicine. The author describes the processes undertaken to date at the California College of Podiatric Medicine (CCPM), as well as the vision of tomorrow, for podiatric medical education. The educational system that will result from these changes will be more efficient; it will better meet the needs of students; and, it will broaden their base of knowledge, all to improve care given to the patient.

Perioperative considerations in the arthritic patient.

It should become clear that the surgeon's responsibility to the patient does not end with knowledge of the surgical procedure. The arthritis patient poses a vexing problem in a variety of ways. The surgeon not only has to understand the particulars of surgery, but also should have a working knowledge of the disease process so that the chance for complications is lessened. Because discussion of each articular disorder is beyond the scope of this article, readers should continually try to review these areas, especially in light of the everchanging attitudes in rheumatology. The arthritis patient is prone to many potential problems, some avoidable and others inevitable. It is obviously the avoidable ones that we most concern ourselves with. Because the patient with arthritis very commonly undergoes multiple reconstructive surgeries, the risks of complications are naturally greatly increased. To any patient with chronic disease, any misfortunes from surgery are all the more discouraging. The team approach will go a long way in providing the most appropriate care. This has been aptly stated as: "The combination of a radical rheumatologist, a conservative surgeon, a cooperative physiatrist and physical therapist, and an informed motivated patient should lead to the best combination of results obtainable in the present state of the art, and reduce the incidence of complications.

Implant arthroplasty in the rheumatoid arthritic patient.

Implant arthroplasty was introduced with the intention that it would relieve pain, provide stability, provide motion, and allow the part to be mobilized. It is a relatively recent phenomenon and long-term results remain difficult to predict.

Fracture nonunion.

The management of nonunion represents a complex clinical situation requiring an understanding of the pathophysiology. Before initiating treatment, the nonunion must be assessed radiographically. Further evaluation by radionuclide imaging and CT may be applicable. Only then can proper treatment, whether by immobilization, internal fixation with or without incorporation of bone grafts, or electrostimulation, be instituted.

Podiatric metallurgy and the effects of implanted metals on living tissues.

The selection of metals and their alloys for implants and fixation devices represents a composite of desirable properties. The search for appropriate implantable materials began following the acceptance of internal fixation. Advances in the control of septic complications, together with recent metallurgical developments, have resulted in the safe application of metallic implants.

Ankle tenography: a key to unexplained symptomatology. Part I: Normal tenographic anatomy.

Fifty cadaver ankles were examined with ankle tenography. The normal tenographic appearance of the peroneus longus and brevis, posterior tibial, flexor digitorum longus, flexor hallucis longus, anterior tibialis, extensor hallucis longus, and extensor digitorum longus tendons and sheaths are described and illustrated for clinical reference. The baseline measurements and demonstration of the normal radiographic appearance of these tendons should assist in the evaluation of hindfoot foot disability and ankle pain.

Tarsal tunnel syndrome: a manifestation of systemic disease.

In many respects, tarsal tunnel syndrome is analogous to carpal tunnel syndrome. Despite this fact, tarsal tunnel syndrome has lagged far behind its counterpart in recognition and understanding. Thought of as a local compression phenomenon, reports of systemic associations are now being seen with increased frequency. This article reviews both local and systemic considerations for tarsal tunnel syndrome. Analysis of our own group of patients revealed 49 with electrodiagnostically confirmed tarsal tunnel syndrome, 24 of whom had bilateral involvement. The incidence of systemic disease was found to be 34.7%.

Functional and surgical anatomy of the lateral ankle.

Inversion ankle injuries resulting in soft tissue injury or various types of fractures are seen frequently by podiatrists, and diagnosis and evaluation of treatment require a thorough knowledge and understanding of the anatomy of the area. In this paper, the authors approach the anatomy from the point of view of surgical dissection, with emphasis on the soft tissue structures. X

Arthroscopic monopolar radiofrequency thermal stabilization for chronic lateral ankle instability: a preliminary report on 10 cases.

This study represents a preliminary review of 10 patients having undergone arthroscopic monopolar thermal stabilization for ankle instability from October 1996 to June 1998. All patients in this study expressed mild to moderate chronic ankle instability complaints and were dissatisfied with their attempts at conservative care. Subjective clinical results were evaluated in all patients having undergone this procedure utilizing a modified version of the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. In addition, eight of these patients underwent pre- and postoperative stress radiographs. The average age of the patient population in this study was 34.5 +/- 9.26 years. The preoperative AOFAS scores averaged 58.3 +/- 8.96 and the postoperative were 88.1 +/- 11.09 points. Patients returned to full activities on the average of 3 months. Postoperative ankle varus stress test reduced on the average of 2.8 degrees +/- 2.77 degrees, while the anterior drawer measurements reduced 4.8 +/- 1.83 mm. The reduction in anterior drawer test amounted to an approximate 60% decrease in talar excursion postoperatively. All patients who underwent this procedure achieved ankle stability and commented that they would undergo the procedure again.

In situ tibialis posterior to flexor digitorum longus tendon transfer for tibialis posterior tendon dysfunction: a simplified surgical approach with outcome of 11 patients.

Outcomes for 11 patients who underwent an in situ tibialis posterior tendon to flexor digitorum longus tendon side-to-side anastamosis as the sole procedure for stage 2 tibialis posterior tendon dysfunction were reviewed. The average follow-up was 34.4 months. Using the American Orthopedic Foot and Ankle Society hindfoot rating scale, a mean improvement of 39.3 points was achieved, with preoperative scores of 38.8 improving to 78.1 postoperatively. Good to excellent results were achieved in nine patients. The in situ side-to-side anastamosis is technically easier to perform, has less tissue trauma, and compares favorably with other soft-tissue procedures and reconstructions for stage 2 tibialis posterior tendon dysfunction. Performing this transfer alone, while leaving the flexor digitorum longus tendon intact, theoretically provides a stronger transfer as the length-tension relationship of the flexor digitorum longus tendon is maintained near its physiologic level. The procedure can consistently restore inversion ability to the rearfoot and stop the progression of tibialis posterior tendon dysfunction.
