The aim of this study was to evaluate the clinical features and functional results of patients with parosteal lipomas.
A total of 12 patients (8 females and 4 males; mean age: 45 (10-62) years) with parosteal lipomas who were treated between April 1986 and April 2014, were included into the study. The medical records of the patients were reviewed to analyze the clinical features and functional results of the patients.
Of the 12 lipomas, 5 were localized in the proximal arm, 4 in the forearm, 1 in the distal arm, 1 in the distal thigh and 1 in the distal tibia. All patients presented with a progressive, slow-growing mass that was associated with thumb extension weakness in 1 case, and brachialgia-like symptoms in 1 case. Plain radiographs showed a juxtacortical mass in all cases and irregular ossification in 3 cases. In all cases, marginal excision was performed and no clinical recurrence was observed after a mean follow-up of 16 months.
Parosteal lipomas are uncommon tumors that can be diagnosed with their characteristic radiological features. Parosteal lipomas occurring in the proximal radius may easily cause paralysis of the posterior interosseous nerve or muscle weakness.

本研究旨在评估骨旁脂肪瘤患者的临床特征及功能结果。
本研究纳入了1986年4月至2014年4月期间接受治疗的12例骨旁脂肪瘤患者（8例女性，4例男性；平均年龄：45（10 - 62）岁）。回顾患者的病历以分析其临床特征及功能结果。
12例脂肪瘤中，5例位于上臂近端，4例位于前臂，1例位于上臂远端，1例位于大腿远端，1例位于胫骨远端。所有患者均表现为进行性生长缓慢的肿块，其中1例伴有拇指伸展无力，1例出现臂痛样症状。X线平片显示所有病例均有皮质旁肿块，3例有不规则骨化。所有病例均行边缘切除术，平均随访16个月后未观察到临床复发。
骨旁脂肪瘤是罕见肿瘤，可通过其特征性影像学表现进行诊断。发生于桡骨近端的骨旁脂肪瘤可能易导致骨间后神经麻痹或肌肉无力。
四级，治疗性研究。
