Soft-tissue impingement syndrome is now increasingly being recognized as a significant cause of chronic ankle pain. The aim of this study was to investigate the diagnostic accuracy of contrast-enhanced, fat-suppressed, three-dimensional (3D), fast-gradient-recalled acquisition in the steady state with radio-frequency-spoiling (CE 3D-FSPGR) magnetic resonance imaging (MRI), and to evaluate the clinical outcome of arthroscopic treatment of soft-tissue impingement associated with the ankle trauma.
This study reviewed 38 patients who had preoperative MRI and arthroscopic treatment of chronic ankle pain after trauma. The CE 3D-FSPGR MRI was used to evaluate the chronic ankle pain, and the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score was used to evaluate the clinical results after arthroscopic treatment.
The CE 3D-FSPGR MRI showed a sensitivity of 91.9%, a specificity of 84.4%, and an accuracy of 87.5% in diagnosing synovitis and soft tissue impingement. All patients had excellent or good outcomes after arthroscopic debridement.
The results of this study suggest that a preoperative fat-suppressed CE 3D-FSPGR MRI is highly beneficial in diagnosing synovitis and soft-tissue impingement and that arthroscopic debridement of the synovitis or soft-tissue impingement has a good clinical outcome.
软组织撞击综合征如今越来越被认为是慢性踝关节疼痛的一个重要原因。本研究的目的是调查对比增强、脂肪抑制、三维(3D)、稳态下带射频扰相的快速梯度回波采集(CE 3D-FSPGR)磁共振成像(MRI)的诊断准确性,并评估踝关节创伤相关软组织撞击的关节镜治疗的临床结果。
本研究回顾了38例创伤后慢性踝关节疼痛且接受了术前MRI和关节镜治疗的患者。采用CE 3D-FSPGR MRI评估慢性踝关节疼痛,并使用美国矫形足踝协会(AOFAS)踝-后足评分评估关节镜治疗后的临床结果。
CE 3D-FSPGR MRI在诊断滑膜炎和软组织撞击方面显示出91.9%的敏感性、84.4%的特异性和87.5%的准确性。所有患者在关节镜清创术后均获得了优良结果。
本研究结果表明,术前脂肪抑制的CE 3D-FSPGR MRI对诊断滑膜炎和软组织撞击非常有益,并且关节镜下对滑膜炎或软组织撞击进行清创具有良好的临床结果。
