摘 要:
This section of a two-part series on musculoskeletal disorders associated with HIV infection and AIDS reviews the non-infectious musculoskeletal conditions. In the first part, the infectious conditions were reviewed. The non-infectious conditions include polymyositis, drug-induced myopathy, myositis ossificans, adhesive capsulitis, avascular necrosis, bone marrow abnormalities, and hypertrophic osteoarthropathy. Inflammatory and reactive arthropathies are more prevalent in HIV-positive individuals, and a separate section is dedicated to these conditions, including Reiter's syndrome, psoriatic arthritis, HIV-associated arthritis, painful articular syndrome, and acute symmetric polyarthritis. Lastly, we include a discussion of HIV-related neoplastic processes that affect the musculoskeletal system, namely Kaposi's sarcoma and non-Hodgkin's lymphoma. Copyright 2004 ISS [References: 53]

摘 要:
Standard theory assumes that osteoarthritis is a catabolic disease, characterised by cartilage destruction brought about by absolute or relative overload. This theory fits the observed facts in secondary osteoarthritis, but when it is tested against the idiopathic disease, the disease profile includes many phenomena which are difficult to reconcile with the overload theory. It incorporates, for example, no adequate explanation for the prevalence patterns observed in human and primate epidemiology, the idiosyncratic distribution, the sparing of the ankle and wrist joints, the production of osteoarthritis by immobilisation, the anabolic dominance of early disease, and several pathological changes including the osteophyte, the reduplicated tide-mark, and the extra-articular contracture. The evidence better fits the concept of two different diseases with a possible, but not obligatory, final common pathway. In the case of the idiopathic disease, the unused arc hypothesis proposed 50 years ago by Harrison et al., reinforced with the concepts of synovial stasis and positive feedback, tests better against the evidence than the overload paradigm. These proposed adjuncts to the hypothesis are speculative and as yet untested. The results could be of more than academic interest. If the unused arc hypothesis turns out to be correct, idiopathic osteoarthritis should be preventable and conceivably, in its early stages, arrestable. Copyright 2004 ISS [References: 49]

摘 要:
OBJECTIVE: To review MR imaging of figure skaters and snowboarders presenting with painful soft-tissue swelling of the lateral supramalleolar region with a clinical provisional diagnosis of soft-tissue tumor. DESIGN AND PATIENTS: MR imaging was prospectively reviewed by two sub-specialized musculoskeletal radiologists. The findings were correlated with a second clinical review and examination of the shoe wear. The patients were four female athletes undergoing heavy training regimes, ranging in age between 16 and 25 years. Two patients were elite figure skaters, and two were professional snowboarders. Three patients had unilateral masses with pain, and one patient presented with bilateral clinical findings. RESULTS: MR imaging showed subcutaneous, focal soft-tissue masses of the supramalleolar region in five ankles at the same level above the ankle joint. MR imaging prompted a second clinical review and correlation with the shoe wear. The MR imaging findings correlated to the level of the shoe rim or shoe buckle in all patients, confirming the suspected MR imaging diagnosis of an impingement syndrome. All four sportswomen were training excessively, ignoring safety advice regarding training duration, timing of breaks, and shoe wear rotation. CONCLUSION: Ice skaters and snowboarders may present with persistent and disabling pain. On MR imaging, this corresponds to a focal soft-tissue abnormality, which may be due to subcutaneous fat impingement between the fibula and the shoe rim or shoe buckle. Copyright 2004 ISS

摘 要:
OBJECTIVE: To determine the prevalence and diagnostic significance of fluid-fluid levels (FFLs) in focal bone lesions. DESIGN AND PATIENTS: Clinical and radiological details of 738 consecutive patients referred with focal lesions of bone and who had undergone MRI were reviewed. FFLs were identified in 83 (11.2%). The proportion of the lesion occupied by FFLs was estimated, based on imaging in all available planes, as <1/3, 1/3-2/3, >2/3 but not the entire lesion, and complete. The degree of FFL change in each lesion was correlated with the final diagnosis, which was either histological (n=80) or clinicoradiological (n=3). There were 31 female and 52 male patients, mean age 25.5 years (range 5-83 years). RESULTS: Histology revealed 46 benign, 32 malignant and 2 non-neoplastic lesions. A clinicoradiological diagnosis was made in the 3 lesions without histology: 2 were benign (simple bone cyst and intraosseous lipoma) and 1 malignant (a metastasis). Malignant neoplasms commonly showed FFLs which occupied <1/3 of the entire lesion (n=22/32, 68.8%), and 50% of all the lesions in this group were conventional intramedullary osteosarcomas (n=16). With increasing FFL change, malignancy became less frequent: with >2/3 (but incomplete) FFL change, 81% (n=13/16) of tumours were benign. If the entire tumour showed FFL change, the histology was benign in 100% (n=11). CONCLUSIONS: The extent of FFLs within a focal bone lesion appears to be inversely related to the degree of malignancy. If at least 2/3 of the lesion shows FFL change, 89% of diagnoses are benign.

摘 要:
OBJECTIVE: To explore how the size of the growth plate changes with age using three-dimensional (3D) models of the distal femoral and proximal tibial growth plates in pediatric patients. DESIGN AND PATIENTS: We retrospectively created 3D models of the normal unaffected distal femoral (n=20) and proximal tibial (n=10) growth plates in 14 patients (9 males, 5 females) age range 3.8-15.6 years who were referred for evaluation of premature partial closure of the growth plate or hyaline cartilage abnormality. All patients had one or more 3D fat-suppressed spoiled GRASS sequence from which models were made of normal growth plates. Total projected area was estimated from standardized maximum intensity projection (MIP) views, and volume was computed from the entire model. We also included the total projected area of the distal femur (n=7) or proximal tibia (n=8) in 11 patients (8 males, 3 females, 5-13 years) who had previously been evaluated for bone bridging. RESULTS: The 3D femoral and tibial growth plate anatomy was displayed. Femoral growth plate area varied from 804 mm2 to 3,463 mm2. Femoral physeal cartilage volume varied from 2.1 cm3 to 12.6 cm3. Tibial growth plate area varied from 736 mm2 to 3,026 mm2. Tibial physeal cartilage volume varied from 1.9 cm3 to 13.2 cm3. The growth plate area values appear to increase linearly with increasing age. CONCLUSIONS: The distal femoral and proximal tibial physeal plates have complex anatomy. Both area and volume of the growth plates appeared to follow a linear increase with age and reached a plateau in adolescence, although there was some scatter. Area appears to have less measurement variability than volume, and may be a more reliable predictor of growth plate tissue quantity. Copyright 2004 ISS

摘 要:
BACKGROUND: The delta phalanx, also known as the delta bone, or longitudinal epiphyseal bracket (LEB), has been described in a variety of syndromes and dysplasias. However, the "kissing delta phalanx" is not as well recognized in the literature; it consists of a duplicated longitudinal bracketed epiphysis, or a complex of two adjacent delta bones, with opposing convex portions facing each other. Magnetic resonance imaging of the kissing delta phalanx has not been previously described. OBJECTIVE: To describe the evolution, variation and associated osseous anomalies of the kissing delta phalanx in three patients with distinct distal limb malformations using both plain films and magnetic resonance imaging. RESULTS: Patient 1 had Rubinstein-Taybi syndrome and, in addition to a kissing delta phalanx in both feet, had corresponding delta metatarsals (MT1). Patient 2 had Cenani-Lenz syndactyly with distinct variation of the kissing delta phalanx in each hand. He had a disorganized appearance to the phalanges, metacarpal fusions and carpal coalitions. Patient 3 had an isolated oligosyndactyly of the left hand with metacarpal fusions and carpal coalitions. All three patients were followed over time. We describe two types of kissing delta phalanges: separated (without fusion of the corresponding epiphyseal brackets) and nonseparated (with fusion of the corresponding epiphyseal brackets). Both types can be seen in the same patient and are a reflection of the relative degree of segmentation of the two delta bones. CONCLUSION: The appearance of this rare osseous abnormality changes with time and can be found in a limited number of uncommon disorders. It can also be found in association with other osseous anomalies of the distal extremities; therefore magnetic resonance imaging early in life can greatly assist in surgical planning. Recognition of the kissing delta phalanx may be an important radiological clue to diagnosis of these rare disorders. Copyright 2004 ISS

We describe the radiological and pathological findings of two cases of calcific haemorrhagic bursitis, one involving the superficial infrapatellar bursa and the other the prepatellar bursa. It was the presence of dystrophic calcification within the lesion that suggested a mineralizing soft tissue sarcoma such as synovial sarcoma. As the radiographic and MR features of the two conditions can be similar but the appropriate management very different, rare calcifying haemorrhagic bursitis needs to be included in the differential diagnosis of masses adjacent to the knee joint showing calcification.

Baker's cysts are fluid distensions of the gastrocnemius-semimembranosus bursa and are the most common cystic lesion around the knee. Typically cysts enlarge along intermuscular planes around the knee. We report three cases in which the expanding cyst did not respect these planes and dissected along an intramuscular route as confirmed by MR imaging. Such behaviour by Baker's cysts is hitherto unreported in the literature. Possible mechanisms to account for this phenomenon are discussed. Copyright 2004 ISS
