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.

Radiographic evaluation of inflammatory arthritis of the foot.

This article provides a brief overview of the radiographic appearance of the more commonly encountered arthridities in the foot. Also reviewed is a stepwise approach to interpreting radiographs in a patient suspected of having a synovial-based disease.

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.

Antibiotic-impregnated bone cement: an in vitro comparative analysis.

This manuscript examines the in vitro antibacterial activity of eight different antibiotics when mixed with polymethyl methacrylate. Two different parameters are presented as being important considerations in the choice of antibiotic. One parameter is the bacterial inhibition created by the direct contact of the antibiotic-impregnated bone cement. The second parameter is the bacterial inhibition produced by diffusion of antibiotic from the bone cement into the surrounding liquid medium. These two experimental models were created to establish the contiguous and remote antimicrobial effects of antibiotic-impregnated bone cement.

Complications of subtalar arthroereisis.

Arthroereisis procedures involving the subtalar joint in the pediatric flatfoot have had great success in limiting/preventing abnormal or destructive pronating forces transmitted into the foot. This report presents actual and potential complications of these procedures.

Cyst and cystlike lesions of the foot.

A variety of cyst and cystlike lesions may present in the osseous structures of the foot. Such lesions are infrequent in their occurrence, and often cannot be diagnosed on the basis of radiographic appearance. In addition to the morphologic data that can be derived from evaluation of standard radiographs, other diagnostic radiographic studies such as tomography, CT scanning, radionuclide bone imaging, angiography, or other studies may be required to ascertain the nature and extent of cystlike lesions of the foot. This is dependent on histopathologic information derived from biopsy. A variety of cyst and cystlike lesions of the foot are presented with a review of their basic morphology and histopathologic, clinical, and prognostic characteristics.

Non-steroidal anti-inflammatory drugs in podiatric medicine and surgery.

This paper presents a review of nonsteroidal anti-inflammatory drugs (NSAIDs) in podiatric medicine and surgery. Although these agents possess a high degree of safety and efficacy, proper patient selection, monitoring, and early detection of side effects are emphasized. A discussion of prostaglandin biochemistry and physiology is included.

Opening base wedge osteotomy of the first metatarsal utilizing rigid external fixation.

The authors describe their operative approach to metatarsus primus adductus deformity when present in conjunction with a congenitally short first metatarsal. Hallux abducto valgus correction in this clinical setting has traditionally advocated use of a crescentic or opening wedge osteotomy in order to prevent further shortening of the first metatarsal. Fixation of opening base wedge osteotomies has been fraught with problems in the past, with possibilities for displacement or eventual loss of initial correction. The authors have found the mini-Hoffmann external fixation device useful for this purpose.

Adolescent hallux valgus: its etiology and surgical management.

Although most patients who seek relief are adults, the problem of hallux valgus frequently begins at an earlier age. In the juvenile patient, except for congenital anomalies or inflammatory juvenile rheumatic disease, hallux abducto valgus appears to be related to the biochemical malfunction. It requires not only surgical management, but also the use of orthotics or surgical stabilization.

A statistical analysis on the reliability of the proximal articular set angle.

The authors investigated the statistical relationship and significance between the transverse and sagittal plane proximal articular set angles both radiographically and intraoperatively. The analysis revealed a highly significant difference between the means of the respective measurements. Although the radiographic and intraoperative findings were found to be related for the transverse plane proximal articular set angle, the transverse plane PASA was approximately 7 degrees greater when measured intraoperatively. The concept of a sagittal plane PASA was also introduced. The significance of accurate measurements in the surgical correction of hallux valgus was also examined.
