The aim of this study was to present clinical and radiological outcomes of surgical treatment for proximal femur unicameral bone cysts (UBCs) in children.
Pediatric patients recruited from our institution between 2015 and 2024 with proximal femur UBC were analyzed retrospectively. Patients were divided into two groups according to whether internal fixation was used. Demographics, cyst activity, cyst area, healing time of pathological fractures and cysts, clinical and radiological outcomes, time to activity and complications were analyzed.
Thirty-seven pediatric patients were included in this study. There were 18 patients in the non-internal fixation group and 19 patients in the internal fixation. There was no significant difference between these two groups in terms of age, duration of follow-up, fracture at diagnosis, cyst activity or healing time of pathological fractures and cysts. Cyst area in the internal fixation group was 1609±1131 mm, which was significantly greater than that in the group without internal fixation (936±597 mm, <0.05). There was no significant difference in clinical or radiological outcomes between the two groups. Patients who were treated with internal fixation were able to return to activity significantly sooner than those who were not (5.9 months 7.7 months; <0.05). There was no significant difference in complications between the two groups (=1.000).
Surgical treatment of proximal femoral UBCs in children remains a challenge. The use of internal fixation is beneficial for accelerating the healing process and reducing the time to activity.
本研究旨在呈现儿童股骨近端单房性骨囊肿（UBC）手术治疗的临床和影像学结果。
回顾性分析2015年至2024年在本机构招募的股骨近端UBC患儿。根据是否使用内固定将患者分为两组。分析人口统计学、囊肿活性、囊肿面积、病理性骨折和囊肿的愈合时间、临床和影像学结果、恢复活动时间及并发症。
本研究纳入37例儿科患者。非内固定组18例，内固定组19例。两组在年龄、随访时间、诊断时骨折情况、囊肿活性或病理性骨折和囊肿的愈合时间方面无显著差异。内固定组囊肿面积为1609±1131mm，显著大于非内固定组（936±597mm，P<0.05）。两组临床或影像学结果无显著差异。接受内固定治疗的患者比未接受内固定治疗的患者恢复活动的时间显著更早（5.9个月对7.7个月；P<0.05）。两组并发症无显著差异（P=1.000）。
儿童股骨近端UBC的手术治疗仍然是一项挑战。使用内固定有利于加速愈合过程并缩短恢复活动时间。
