To investigate the effectiveness of the Evans lateral lengthening calcaneal osteotomy (E-LLCOT) in treatment of talocalcaneal coalition (TCC) with hindfoot valgus deformity.
Between January 2014 and October 2017, 10 patients (13 feet) of TCC with hindfoot valgus deformities underwent E-LLCOTs. There were 6 males (8 feet) and 4 females (5 feet) with an age of 13-18 years (mean, 15.8 years). The disease duration was 10-14 months (mean, 11.5 months). The foot deformity was characterized by hindfoot valgus, forefoot abduction, and collapse of the medial arch. Pain site was the tarsal sinus in 4 feet, TCC in 5 feet, and ankle joint in 4 feet. There were tightness of the gastrocnemius in 3 cases (4 feet) and Achilles tendon in 7 cases (9 feet) on Silverskiold test. The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 46.54±9.08 and visual analogue scale (VAS) score was 6.54±0.88 after walking 1 kilometer. The AOFAS ankle-hindfoot score and VAS score were adopted to evaluate the postoperative function of the foot. The talar-first metatarsal angle (T1MT), talonavicular coverage angle (TCA), talar-horizontal angle (TH), calcaneal pitch angle (CP), and heel valgus angle (HV) were measured after operation.
All incisions healed by first intention. All patients were followed up 12-30 months (mean, 18 months). At last follow-up, the AOFAS ankle-hindfoot score and VAS score were 90.70±6.75 and 1.85±0.90, respectively, showing significant differences when compared with preoperative scores ( =-23.380, =0.000; =35.218, =0.000). X-ray films showed that the osteotomy healed at 2-4 months (mean, 3 months) after operation. At last follow-up, the T1MT, TCA, TH, and HV were significantly lower than preoperative ones ( <0.05), and the CP was significantly higher than preoperative one ( <0.05). During the follow-up, the pain did not relieve obviously in 1 patient (1 foot), and the cutaneous branch of the sural nerve injured in 1 patient (1 foot).
For TCC with severe hindfoot valgus deformity, E-LLCOT can effectively correct deformity and relieve pain.
探讨伊文斯外侧延长跟骨截骨术(E-LLCOT)治疗伴有后足外翻畸形的距下关节联合(TCC)的有效性。
2014年1月至2017年10月,10例(13足)伴有后足外翻畸形的TCC患者接受了E-LLCOT手术。其中男性6例(8足),女性4例(5足),年龄13 - 18岁(平均15.8岁)。病程10 - 14个月(平均11.5个月)。足部畸形表现为后足外翻、前足外展和内侧足弓塌陷。疼痛部位:跗骨窦4足,TCC 5足,踝关节4足。在西尔弗斯基德试验中,3例(4足)腓肠肌紧张,7例(9足)跟腱紧张。术前美国矫形足踝协会(AOFAS)踝后足评分为46.54±9.08,行走1公里后的视觉模拟量表(VAS)评分为6.54±0.88。采用AOFAS踝后足评分和VAS评分评估术后足部功能。术后测量距骨 - 第一跖骨角(T1MT)、距舟覆盖角(TCA)、距骨水平角(TH)、跟骨倾斜角(CP)和足跟外翻角(HV)。
所有切口均一期愈合。所有患者均随访12 - 30个月(平均18个月)。末次随访时,AOFAS踝后足评分和VAS评分分别为90.70±6.75和1.85±0.90,与术前评分相比差异有统计学意义(=-23.380,=0.000;=35.218,=0.000)。X线片显示截骨术后2 - 4个月(平均3个月)愈合。末次随访时,T1MT、TCA、TH和HV均显著低于术前(<0.05),CP显著高于术前(<0.05)。随访期间,1例患者(1足)疼痛缓解不明显,1例患者(1足)腓肠神经皮支损伤。
对于伴有严重后足外翻畸形的TCC,E-LLCOT能有效矫正畸形并缓解疼痛。
