The etiopathogenesis of reflex sympathetic dystrophy is still undefined, and diagnosis and treatment are difficult. It is the purpose of this study to propose precise diagnostic and therapeutic criteria for post-traumatic reflex sympathetic dystrophy of the ankle and foot. Diagnosis is pre-eminently clinical. Clinical progression of the disease occurs in three stages: acute, dystrophic, chronic. Radiographic examination cannot be used to classify the stage of the syndrome. Bone scan with Tc 99M methylendiphosphonate aids diagnosis, and helps establish the prognosis of the disease. Clinical symptoms and instrumental tests (x-ray, bone scan, CT scan, MRI) are discussed in relation to differential diagnosis with other pathologies of the ankle and foot. Furthermore, the effective use of drugs, physiokinesitherapy, and hyperbaric oxygen therapy is discussed. The authors present a study of 32 patients, paying close attention to early clinical signs of the disease. X-ray examination and bone scan were routinely carried out in established diagnostic protocols.

It is the purpose of this study to analyze the data found in the literature and to compare our experience with that of other traumatology centers. A series of patients observed between 1985 and 1996 were reviewed. Nine out of 12 patients with sequelae related to dislocation of the knee were re-evaluated. Based on an analysis of the results, obtained by using the International Knee Documentation Committee (IKDC) form, it was concluded that the patients treated surgically are better overall. It is possible only rarely to obtain satisfactory recovery in work and/or sports activity, as the lesion is severe and even when treated it leaves functional and/or structural sequelae of varying importance.

Since the introduction of more effective antiretroviral therapy in HIV treatment, an increase in survival and in the quality of patients' life has been observed, due to the dramatic reduction in commonly occurring opportunistic diseases. The appearance of new clinical cases has, however, been observed, previously unrecorded probably due to the quicker negative evolution of AIDS. Pathologies such as lypodistrophy, cardiomyopathy, immune disease, are extremely widespread and partly linked to the natural history of HIV infections, and partly to the side effects of the treatments. Among such diseases, femoral head necrosis seems to occur fairly frequently and is characterised by a quick evolution. The emergence of coxalgia in HIV patients requires an early diagnosis through NMR or bone scan. Given the usual evolution of this pathology and the problems related to antiviral treatment, conservative treatment seems to have little possibility of success. A surgical replacement becomes essential in cases of invalidating necrosis, but there are still unresolved questions as regards risks of infection, bone integration, as well as local and systemic reactions to the prosthetic debris.

Conventional radiography, ultrasound, Magnetic Resonance (MR), Arthrography Computed Tomography (Arthro-CT) and Arthrography Magnetic Resonance (Arthro-MR) are available for diagnosis of rotator cuff tears. Our purpose is to assess the specificity and sensitivity of these examinations and if they could give to the surgeon all the informations to select the more accurate treatment. We have evaluated retrospectively the images of 68 patients, 43 male and 25 female (average age 51 years), which then have been surgically treated for rotator cuff pathology. On the basis of our findings, we think that conventional radiography and ultrasound are excellent in a first evaluation. MR images, particularly in the coronal and sagittal oblique planes, are able to demonstrate partial or complete rotator cuff tears. The use of intra-articular contrast medium (arthro-CT, arthro-MR) should be reserved for partial lesions on specific cases.
