Thirty-six patients with arthrogryposis have been followed at The James Lawrence Kernan Hospital of Baltimore since 1951. In this group, nine patients sustained 16 perinatal fractures. Femoral shaft fractures and epiphyseal separations were found more commonly in patients with fixed knee extension or dislocated hips and were related to relative stiffness and obstructed delivery. Femoral fractures were more common than humeral or tibial fractures. Arthrogrypotic infants displaying irritability and poor feeding are suspect of skeletal trauma. Thickening of limbs or joints may be the only clinical indication of fracture of epiphyseal injury. Plain radiographs of joints were inadequate for the diagnosis of epiphyseal separation when the epiphysis was not yet ossified. Arthrography is therefore recommended as a primary diagnostic tool.
自1951年以来，巴尔的摩的詹姆斯·劳伦斯·克南医院对36例关节挛缩症患者进行了随访。在这组患者中，9例患者发生了16例围产期骨折。股骨干骨折和骨骺分离在膝关节固定伸展或髋关节脱位的患者中更为常见，并且与相对僵硬和分娩受阻有关。股骨骨折比肱骨或胫骨骨折更常见。表现出易怒和喂养困难的关节挛缩症婴儿怀疑有骨骼创伤。肢体或关节增厚可能是骨骺损伤骨折的唯一临床指征。当骨骺尚未骨化时，关节的X线平片不足以诊断骨骺分离。因此，建议将关节造影作为主要诊断工具。
