摘要:

文题释义:
平足症:又称扁平足,指足弓低平或消失,患足外翻,站立、行走时足弓塌陷,引起足部疼痛的一种畸形。很多平足者特别是儿童平足没有症状,也不需要治疗,只有少部分儿童平足可能会逐渐引起整个身体体态的变化,有一部分平足可能合并足部骨结构异常,如垂直距骨、跗骨联合等。
距下关节制动:涉及放置一个植入物于跗骨窦,代表着最小的侵入性手术干预。植入物可以防止不正常的踝关节旋转,这样能够保证在动态下维持其正常的解剖结构。此技术操作简单,患儿术后恢复快,而其他替代的选择方案则需要更大的手术操作,增加了手术危险性及术后恢复难度。

背景:HyProCure跗骨螺钉已被广泛应用于柔韧性平足症的治疗,但针对合并痛性副舟骨的青少年柔韧性平足症尚无统一的治疗方式。
目的:探讨单纯应用HyProCure跗骨螺钉治疗青少年柔韧性平足合并痛性副舟骨的临床疗效。
方法:选择2015年1月至2019年9月国家康复医院收治的合并痛性副舟骨的柔韧性平足青少年患者24例(39足),其中男13例(22足),女11例(17足),年龄5-15岁,均接受HyProCure跗骨螺钉植入治疗。术后随访目测类比评分和美国足踝外科协会(AOFAS)踝与后足功能评分,拍摄X射线片,测量距骨-第1跖骨角(Meary’s角)、距骨-第2跖骨角、跟骨倾斜角(Pitch角)、距骨倾斜角、跟骨外翻角、距舟覆盖角及距骨跟骨角。研究获得国家康复医院伦理委员会批准。
结果与结论:①术后24例患者切口均Ⅰ期愈合,其中2例(2足)出现跗骨窦区疼痛,1例(1足)术后出现跟骨轻度内翻及第1跖骨头下负重不足,1例(1足)术后残留副舟骨轻度疼痛;②24例患者获得6-36个月随访,未出现螺钉退出及二次手术取出螺钉等情况;③24例患者末次随访时的目测类比评分明显低于术前(P < 0.01),AOFAS踝与后足功能评分明显高于术前(P < 0.01);④24例患者末次随访的Meary’s角、距骨-第2跖骨角、Pitch角、距骨倾斜角、跟骨外翻角、距舟覆盖角及距骨跟骨角均较术前明显改善(P < 0.01或P < 0.05);⑤结果表明,应用HyProCure跗骨螺钉治疗青少年合并痛性副舟骨的柔韧性平足具有良好的短期疗效。

Abstract: BACKGROUND: HyProCure subtalar stabilization has been widely used in the treatment of flexible flatfoot, but there is no unified treatment for adolescent flexible flatfoot with painful accessory navicular bone. 

OBJECTIVE: To evaluate the effectiveness of HyProCure subtalar stabilization for adolescent flexible flatfoot combined with painful accessory navicular bone. 

METHODS: Between January 2015 and September 2019, 24 cases (39 feet) of adolescent flexible flatfoot combined with painful accessory navicular bone were treated with HyProCure subtalar stabilization in National Rehabilitation Hospital. There were 13 males (22 feet) and 11 females (17 feet) with the age of 5-15 years. Visual analogue scale score and American Orthopaedic Foot & Ankle Society (AOFAS) ankle and foot function score were used to evaluate the effectiveness. The talus-the first metatarsal angle (Meary’s angle), the talus-the second metatarsal angle, calcaneal inclination angle (Pitch angle), the talar declination angle, calcaneal valgus angle, talonavicular coverage angle, and talocalcaneal angle were measured on the X-ray films. This study was approved by the Ethics Committee of National Rehabilitation Hospital.  

RESULTS AND CONCLUSION: (1) All incisions of 24 patients healed well in the first stage. Two cases (2 feet) had tarsal sinus pain; one case (1 foot) appeared with mild hindfoot varus and insufficient weight-bearing under the 1st metatarsal head, also one case (1 foot) complained mild painful remain at local site. (2) All 24 patients were followed up for 6-36 months. No case suffered from hardware failure or hardware removal. (3) At last follow-up, visual analogue scale score was significantly decreased compared with that before surgery (P < 0.01); AOFAS ankle and foot function score was significantly increased compared with that before surgery (P < 0.01). (4) At last follow-up, Meary’s angle, the talus-the second metatarsal angle, Pitch angle, the talar declination angle, calcaneal valgus angle, talonavicular coverage angle, and talocalcaneal angle in 24 patients were significantly improved compared with that before surgery (P < 0.01 or P < 0.05). (5) The results suggested that HyProCure subtalar stabilization is effective for adolescent flexible flatfoot combined with painful accessory navicular bone in short term.
