To describe the radiographic and scintigraphic findings of partial transient osteoporosis (PTO) of the hand. To discuss the relationship of PTO and other localized demineralizing diseases.
Three patients with PTO that affected two or three digits of the hand are reported. Two patients were middle-aged women and the third was a young man. All presented with a history of trauma to the hand. All patients experienced localized burning pain, swelling and vasomotor changes including redness of the skin, hyperhidrosis and signs of vasomotor instability of the involved fingers. Plain radiography and bone scanning were used in the diagnosis and follow-up of these cases.
All patients had a radial distribution of the osteoporosis that involved adjacent rays. In all patients two rays were involved. The radiographic changes manifested as minimal patchy osteoporosis involving the cortical, cancellous, subarticular and subperiosteal bone with no articular involvement. The increased uptake on scintigraphy coincided with the radial distribution of the osteoporosis. All patients improved on physical therapy and were symptom-free approximately 6 months after the initial injury. These patients were followed up for more than 2 years.
PTO of the hand is an uncommon disease with typical clinical and radiographic findings. Bone scintigraphy confirms the partial involvement of the hand.
描述手部局限性短暂性骨质疏松症（PTO）的影像学和闪烁扫描表现。探讨PTO与其他局限性脱矿疾病的关系。
报告3例手部两到三个手指受累的PTO患者。2例为中年女性，第3例为青年男性。所有患者均有手部外伤史。所有患者均出现局限性灼痛、肿胀及血管舒缩改变，包括皮肤发红、多汗及受累手指血管舒缩不稳定体征。采用X线平片和骨扫描对这些病例进行诊断和随访。
所有患者骨质疏松均呈桡侧分布，累及相邻的掌骨。所有患者均累及两根掌骨。X线表现为皮质骨、松质骨、关节下骨和骨膜下骨轻度斑片状骨质疏松，未累及关节。闪烁扫描摄取增加与骨质疏松的桡侧分布一致。所有患者经物理治疗后病情改善，初始损伤后约6个月症状消失。对这些患者进行了超过2年的随访。
手部PTO是一种罕见疾病，具有典型的临床和影像学表现。骨闪烁扫描可证实手部的部分受累情况。
