POSTEROLATERAL FUSION AND PEDICLE SCREW FIXATION FOR TREATING OLD THORACOLUMBAR FRACTURE COMBINED WITH KYPHOSIS IN ELDERLY PATIENTS

ObjectiveTo investigate the clinical efficacy and the indications of posterolateral fusion and pedicle screw short-segment fixation via injured vertebra for treating old thoracolumbar fracture combined with kyphosis in elderly patients. MethodsBetween January 2012 and December 2014, 24 patients with old thoracolumbar fracture and kyphosis received posterolateral fusion and pedicle screw short-segment fixation via injured vertebra. Of 24 cases, 8 were male and 16 were female with an average age of 66.3 years (range, 56-79 years). The mean disease course was 17.5 months (range, 5-36 months). There were 13 cases of osteoporosis, 9 cases of osteopenia, and 2 cases of normal bone. The visual analogue scale (VAS) was 6.53±0.95, and Oswestry disability index (ODI) was 52.63%±5.74% preoperatively. The thoracolumbar kyphosis located at T10 to L2, and the kyphotic Cobb angle was (28.79±5.04)° before operation. ResultsThe operation was completed successfully without related complications. The operative time was 1.2-2.3 hours (mean, 1.6 hours), and intraoperative blood loss was 80-210 mL (mean, 158 mL). No nerve injury occurred. Poor healing of incision was observed in 1 patient with diabetes, and primary healing of incision was obtained in the other patients. Nineteen patients were followed up 6-30 months (mean, 14.4 months), and there were 2 deaths. Pain relief and function recovery were obtained in 19 patients after operation. The VAS score and ODI were significantly decreased to 2.4±0.7 and 32.14%±5.12% at last follow-up (t=8.542, P=0.000; t=9.826, P=0.000). The kyphotic Cobb angle was significantly decreased to (21.23±4.30)° at immediate after operation (P < 0.05) and to (23.68±4.35)° at last follow-up (P < 0.05), but no significant difference was found between at immediate and last follow-up (P > 0.05). No loosening or breakage of internal fixation was observed during follow-up. ConclusionPosterolateral fusion and pedicle screw short-segment fixation via injured vertebra is a safe and effective treatment for elderly patients with old thoracolumbar fracture combined with kyphosis (Cobb angle less than 40°).

踇甲皮瓣联合腓动脉穿支皮瓣游离移植再造拇指并修复足部供区 15 例

目的总结应用踇甲皮瓣再造拇指及腓动脉穿支皮瓣游离移植修复足部供区的手术方法及临床效果。方法2016 年 6 月—2018 年 5 月，应用踇甲皮瓣联合腓动脉穿支皮瓣游离移植再造拇指并修复足部供区 15 例。男 10 例，女 5 例；年龄 21～48 岁，平均 34.6 岁。致伤原因：重物压砸伤 7 例，机器绞伤 5 例，电锯切割伤 3 例。Ⅰ度缺损 9 例，Ⅱ度缺损 6 例。入院至皮瓣手术时间 4～7 d，平均 5.2 d。结果术后踇甲皮瓣及腓动脉穿支皮瓣全部成活，切口均Ⅰ期愈合。患者均获随访，随访时间 8～24 个月，平均 16.4 个月。末次随访时，再造拇指指甲生长平整，有光泽，指腹饱满；足部皮瓣外形良好，颜色及质地接近受区。根据中华医学会手外科学会拇手指再造功能评定标准，获优 9 例、良 6 例；根据 Maryland 足功能评分标准，获优 10 例、良 5 例。患者行走步态正常，无跛行及疼痛不适。结论踇甲皮瓣修复拇指Ⅰ、Ⅱ度缺损，再造拇指可获得良好外观及功能；腓动脉穿支皮瓣具有血供可靠、血管恒定、易切取等优点，可有效修复足部供区。
