摘要
目的介绍环锯切骨融合距下关节治疗距下关节痛的方法及临床效果。方法1997年6月～2001年10月,利用环锯(Φ11.5mm、12mm、13mm)对18例距下关节痛患者进行环锯切骨融合,男12例,女6例;年龄35～59岁,平均47岁;右足11例,左足7例;创伤性距下关节炎8例,退变性关节炎5例,先天性跟距骨桥2例,类风湿性关节炎2例,顽固性跗骨窦炎1例。应用100mm视觉模糊疼痛量表VAS测试,80～91分,平均83.8分。踝关节后外侧入路14例,踝关节前外侧入路4例;14例行原锯心骨旋转90°回植融合,4例取髂骨骨柱植骨融合。术后踝关节中立位石膏固定12～16周。结果18例均获得随访,随访时间5个月～4年,平均25个月。术后2周切口一期愈合,4周有骨痂形成,12周应用100mm视觉模糊疼痛量表VAS测试,22～49分,平均32.5分,较术前降低30～59分,平均降低51.3分。均摄X线片示距下关节牢固融合。1例出现轻度足下垂,1例出现行走或长时间站立后足跟部酸胀痛。结论采用环锯切骨融合距下关节的方法治疗距下关节痛,切口小,易显露,不影响后足的生物力学结构。在距下关节原位状态下融合,对距下关节高度及距舟关节稳定性影响不大;应用锯心骨旋转回植不需另植骨。
Objective To introduce a new technique of talocalcaneal joint fusion with trephine and evaluate its clinical effects. Methods From June 1997 to October 2001, 18 cases complained of pain, weakness, limited range of motion and tenderness of ankle were treated with subtalar joint fusion. Of 18 cases, there were 12 males and 6 females with an average age of 47 years (range, 35 to 59 years). The lesions of subtalar joint were identified as traumatic osteoarthritis in 8, degenerative osteoarthritis in 5, congenital bone bridge in 2, rheumatoid arthritis in 2 and refractory inflammation of tarsal sinus. The AP and lateral view X-ray films were taken to measure the width and length of sutalar joint and talocalcaneal angle so as to choose the trephine of appropriate diameter (Φ11.5 mm, 12 mm, 13 mm )and guide the direction and length of osteotomy. Posterolateral approach was used in 14, and anterolateral approach in 4 depending on the location of lesion at subtalar joint. The trephine was inserted into subtalar joint slowly, the bone block inside the trephine was removed, rotated to 90°, then reimplanted in situ in 14 cases; Autograft of iliac crest was harvested and implanted by trephine in 4. Results All of the affected feet were immobilized with a cast postoperatively for 12 to 16 weeks. The patients were followed up for an average of 25 months ranging from 5 months to 4 years. All the wounds healed well at 2 weeks, the callus appeared at 4 weeks, and the bony fusion was obtained at 16 weeks displayed by postoperative X-ray films. The scores of ankle pain by VAS measurement were improved from preoperative 83.8 to postoperative 32.5. There were no severe complications, only 1 case suffered from dropping foot and recovered 10 months later, and 1 case complained of discomfort of foot. Conclusion Subtalar joint fusion with trephination is an effective procedure with many advantages such as: minimal invasive surgery, easy to perform, higher fusion rate and preserving mechanical stability of hind foot.
