Forefoot arthroplasty in the arthritic patient.

The forefoot arthroplasty procedure is frequently used in the patient with inflammatory arthritis. There is a multitude of considerations, both local and systemic, in these patients. As with other surgical procedures, it is important that the surgeon evaluate the patient as a whole. Each case should be evaluated individually and modifications made as necessary. There are several modifications of the original technique as described by Hoffman. Ultimately, the surgeon must select which variation works best in his or her hands. This procedure works extremely well when the patients are carefully selected. Patients greater than 50 years of age tend to do the best. They should demonstrate an apropulsive gait at the time of surgery and have an unrelenting metatarsalgia. Complications frequently arise from inadequate resection of bone, which can cause recurrence of deformity. Some regeneration of bone should be expected postoperatively. Patients should be told that they will lose one to two shoe sizes postoperatively. Despite these problems, this procedure has stood the test of time and should provide a high degree of satisfaction for patient and physician alike.

Special radiographic techniques in the evaluation of arthritic disease.

The radiographic modalities discussed in this article are useful adjunctive techniques in the evaluation of arthritic disease. None of these modalities should be considered for baseline study. Rather, they should be considered following plain film examination when further information is required. The one modality that may be considered for a screening examination is radionuclide imaging. It is most useful when early diagnostic information regarding the extent of pathology is required. A pattern of activity can provide important information to the clinician, enabling an accurate diagnosis. Arthrography is best reserved for the evaluation of articular cartilage of a particular joint. A double-contrast arthrogram should be performed in this case. The technique has little application in the evaluation of polyarticular disease. Tenography is most useful in differentiating tenosynovitis from stenosing tenosynovitis. The differentiation is important because a diagnosis of stenosing tenosynovitis usually necessitates surgical intervention. Spontaneous rupture can be evaluated with tenography, but is is probably best evaluated with MRI. CT may be used in the evaluation of both soft-tissue and articular pathology. It is perhaps best employed in the evaluation of articular pathology of the rearfoot. This technique should not be used as a screening examination for vague foot pain. MRI is the newest and most exciting imaging modality available. The excellent soft-tissue contrast provides an accurate means of evaluating the extraarticular manifestations of arthritic disease. MRI may aid in differentiating rheumatoid nodules from neuromas in rheumatoid patients with excessive forefoot disease. It is also useful in the evaluation of tendon pathology, particularly spontaneous ruptures. This technique is only in its infancy, but technologic advances are rapidly making it a major force in the field of diagnostic imaging.

Computed tomographic scanning of the foot and ankle.

Computed tomography (CT) has become the gold standard for cross-sectional imaging in the foot and ankle. The literature is full of studies and case reports where CT has definately elucidated osseous and soft-tissue pathology.

Magnetic resonance imaging in the foot and ankle.

The first image obtained in a live human with MR was performed in July 1977. It took 4 hours and 45 minutes to produce a single slice. Imaging devices became available routinely in late 1982 and early 1983. Since that time, dramatic technologic growth and improvement has brought MR to the forefront of radiology. It is now believed to be the modality of choice for delineating and staging soft-tissue abnormalities and also shows great promise for evaluating marrow replacing processes. Recently, hyaline cartilage has been identified with MR. Previously in radiology, hyaline cartilage could only be identified when it was outlined by contrast material. Cartilage per se is not a radiographic density. MRI therefore offers potential hope as a cartilage-imaging modality. In addition, the synovium is well delineated with MRI, and it is conceivable that in the future we will use MRI to quantitate synovial proliferation and to monitor response to therapy. The future is quite bright. Currently, spatial resolutions below 1 mm are common with slice thicknesses available at 2 to 2.5 mm. In the future, however, sections will become thinner, spatial resolution will become greater, and localized radiofrequency coils will be developed for specific anatomic regions. Practicing podiatrists should now consider MR a useful tool in the imaging armamentarium.

Radiographic evaluation in the pediatric patient.

A brief overview of the radiographic evaluation of the pediatric foot has been presented. Experience in evaluating the normal foot is a mandatory prerequisite for identifying pathology in the pediatric foot. Specific radiographic techniques have been discussed to enhance the evaluation of individual pathologies in different age groups. Correlation of clinical and radiographic findings is as essential in the pediatric patient as it is in the adult.

Radiographic evaluation of transchondral dome fractures of the talus.

Transchondral fractures of the talar dome have been cited frequently in the literature. The number of radiographic techniques available for the evaluation of these lesions often leads to confusion for the physician. The authors discuss each of the radiographic modalities available for the assessment of this entity. Advantages and disadvantages of these modalities have been presented. This manuscript provides the clinician with the knowledge to perform an appropriate evaluation of the problem.

Acro-osteolysis.

Acro-osteolysis is a common radiographic finding in the upper or lower extremity. It may be idiopathic, part of a primary osteolysis syndrome, associated with a systemic disorder, traumatically induced, or caused by environmental toxins. Recognition of this process and its associated disorders is essential for complete patient care. This paper discusses the definition, etiologies, pathogenesis, and radiographic findings of acro-osteolysis.

Rheumatoid nodulosis in the foot: a variant of rheumatoid disease.

Rheumatoid nodulosis is a relatively benign variant of rheumatoid disease. This entity has been previously ignored in the medical literature. Confusion with other diseases that can produce nodules is not infrequent. A discussion of this entity, as well as a case report, will be presented.
