[Semiological profile of avascular necrosis of the femoral head in patients with AA and AS hemoglobins]

To search a possible difference in the avascular necrosis of femoral head expression in patients with AA and AS hemoglobins seen at the lome teaching hospital rheumatology clinic [Togo L medical records of patients seen at the Lome T Hospital rheumatology clinic [Togo] during 17 years were s Have been included in the present study the patients affected avascular necrosis of the femoral head and having been the objx.2 hemoglobi electroophoresis [79 patients: AS hemoglobii patients] AA hemoglobin [50 patients]. The comparison o parameters rested on the analysis of variance. epidemiological and semiological comparison of avascular necrosis of the femoral bead between the patients with hemoglobin and those having a normal hemoglobin didn't she statistically significant difference. Conclusion: the presence of AS hemoglobin in avascular necrosis the femoral head patients must not influence the gait aiming search of an etiology or risk factor

[Topographic patterna of osteoarthritis of appendicular joints in patients attending a teaching hospital clinic]

Determine the prevalence and topographic patterns of osteoarthritis. Medical records of patients seen at the Lome Teaching Hospital rheumatology clinic [logo] were studied retrospectively. Among the 12251 patients seen over a 15 year period, 1085 had appendicular osteoarthritis. Mean age at onset was 50, 3 years [extremes: 7 and 85 years], and mean duration of osteoarthritis was 4, 4 years. Principal distribution of affected joints was as follows: knee, 993 patients [844 females, 85%; 149 males]; hip, 77 patients [primary osteoarthritis: 36 patients, secondary osteoarthritis: 41 patients]; scapulohumeral joint, 5 patients; and fingers, 5 patients. At the knee, the lesions involved the medial femorotibial compartment in 493 patients [unilateral: 117 patients, bilateral: 376 patients], the lateral femorotibial compartment in 223 patients [unilateral: 74 patients, bilateral: 149 patients] and the patellofemoral compartment in 42 patients [unilateral: 17 patients, bilateral: 25 patients]. Mean age at onset of knee osteoarthritis was 50, 3 years. Among females with knee osteoarthritis, 83%were obese and 63, 5%had varus or valgus deformities. This study confirms that in black Africa the high prevalence of knee osteoarthritis contrasts with the low prevalence of primary osteoarthritis of the hip and of osteoarthritis of the fingers. Female sex, obesity, and varus or valgus deformities are the main risk factors for femorotibial osteoarthritis in black Africa
