Subungual osteochondroma (SO) is an infrequent and non-malignant bone tumour of the distal phalanx, especially prominent in paediatric populations. The aim of this research was to describe a case series of paediatric feet with SO which received surgical treatments. The secondary purpose was to compare these descriptive data by sex distribution.
Twenty-three paediatric feet with SO confirmed by clinical or radiological features received surgical treatment. Socio-demographic (age, sex, height, weight and BMI) and clinical features (side, location, tumour or pain presence, and nail lift before surgery, as well as recurrence and adverse effects at one month after intervention) were reported.
Regarding clinical features before intervention, the most frequent locations of SO were the first toe (86.8%) and the right lower limb (56.5%). In addition, the presence of the tumour, pain and nail lift showed a prevalence of 91.3%, 69.5% and 47% of the study sample, respectively. Considering clinical features at one month after intervention, the most frequent adverse effect was the pain presence (69.5%). In addition, one case (4.4%) presented ulceration. Only one patient (4.4%) suffered from recurrence with a new tumour. There were not statistically significant differences by sex distribution ( > 0.05).
This novel study showed that surgery treatment for SO in paediatric populations presented a very low recurrence degree with minor adverse effects and without differences by sex distribution. Thus, further randomized clinical trials should be carried out in order to determine the effectiveness of this intervention in this special population.
甲下骨软骨瘤（SO）是一种罕见的非恶性指骨远端骨肿瘤，在儿科人群中尤为突出。本研究的目的是描述一系列接受手术治疗的小儿足部SO病例。次要目的是按性别分布比较这些描述性数据。
23例经临床或影像学特征确诊的小儿足部SO接受了手术治疗。报告了社会人口统计学特征（年龄、性别、身高、体重和BMI）和临床特征（患侧、位置、肿瘤或疼痛情况以及术前指甲抬起情况，以及干预后1个月的复发情况和不良反应）。
关于干预前的临床特征，SO最常见的位置是第一趾（86.8%）和右下肢（56.5%）。此外，肿瘤、疼痛和指甲抬起的发生率分别占研究样本的91.3%、69.5%和47%。考虑干预后1个月的临床特征，最常见的不良反应是疼痛（69.5%）。此外，1例（4.4%）出现溃疡。只有1例患者（4.4%）出现新肿瘤复发。按性别分布无统计学显著差异（>0.05）。
这项新研究表明，小儿人群中SO的手术治疗复发率极低，不良反应轻微，且按性别分布无差异。因此，应开展进一步的随机临床试验，以确定该干预措施在这一特殊人群中的有效性。
