作者研究57例镰状细胞贫血的骨关节改变。骨坏死为常见X线征,其次为骨髓炎,而关节炎少见。X线表现:骨坏死多累及干骺端,最常见于股骨上、下干骺端和胫骨上干骺端。广泛骨梗塞见于骨干和干骺端的骨皮质。X线表现为管状骨皮质增厚和硬化以及髓腔内新骨形成、髓腔狭窄和骨膜反应。长骨骨骺骨化中心的缺血坏死表现为斑片状硬化、碎裂、变扁和关节破坏。在髋关节表现为扁平髋。髋臼缺血坏死的表现是髋关节间隙增宽和髓臼
The authors studied bone and joint changes in 57 patients with sickle cell anemia. Osteonecrosis is a common X-ray sign, followed by osteomyelitis, and arthritis is rare. X-ray findings: Most bone necrosis involved the metaphysis, the most common in the upper and lower metatarsal femoral metaphysis. Extensive bone infarcts are found in the cortex of the backbone and metaphysis. The X-ray manifested as thickening and hardening of tubular cortical bone, new bone formation in the medullary cavity, stenosis of medullary cavity, and periosteal reaction. The ischemic necrosis of the ossification center of long bones is characterized by patchy sclerosis, fragmentation, flattening, and joint destruction. The hip shows a flat hip. The manifestation of acetabular anemia is the widening of the hip joint space and the sacral herniation
