  • 第一跖背动脉皮瓣串联足母趾腓侧皮瓣移植修复手部贯通伤

    目的总结采用第1跖背动脉皮瓣串联趾腓侧皮瓣游离移植修复手部贯通伤的疗效。方法2007年1月-2011年12月,采用第1跖背动脉皮瓣串联趾腓侧皮瓣游离移植修复手部贯通伤12例。男8例,女4例;年龄18~52岁,平均35岁。致伤原因:冲床伤9例,火器伤3例。受伤至入院时间3~12 h,平均6 h。患者手掌皮肤缺损范围为2.0 cm×1.5 cm~3.0 cm×3.0 cm,手背缺损范围为3.5 cm×3.0 cm~5.0 cm×4.0 cm。其中合并掌骨缺损或骨折7例,伸肌腱损伤7例,指动脉损伤3例,指总神经损伤6例。供区中厚皮片游离植皮修复。结果术后所有皮瓣及植皮均成活,创面Ⅰ期愈合。12例均获随访,随访时间6~18个月,平均10个月。皮瓣外观满意,末次随访时皮瓣两点辨别觉为0.6~1.0 cm,平均0.8 cm。根据中华医学会手外科学会上肢部分功能评定试用标准评定:获优10例,良2例。结论第1跖背动脉皮瓣串联趾腓侧皮瓣与手部皮肤外观、质地相近,吻合血管易于成活,是修复手部贯通伤的理想皮瓣。

  • APPLICATION OF COMPUTER-ASSISTED SURGICAL PLANNING IN SURGICAL TREATMENT OF ANKLE FRACTURES

    ObjectiveTo explore the clinical value of computer-assisted surgical planning in the treatment of ankle fractures. MethodsBetween January 2012 and January 2014, open reduction and internal fixation were performed on 42 patients with ankle fractures. There were 22 males and 20 females with an average age of 52 years (range, 19-72 years). The causes were spraining injury (20 cases), traffic accident injury (14 cases), and falling from height injury (8 cases). The time from injury to operation was 5 hours to 12 days (mean, 2.5 days). All fractures were closed trimalleolar fractures. According to Lauge-Hansen classification, 25 cases were rated as supination extorsion type IV, 13 as pronation extorsion type IV, and 4 as pronation abduction type Ⅲ. The preoperative planning was made by virtual reduction and internal fixation using Superimage software. ResultsThe mean operation time was 93.7 minutes (range, 76-120 minutes). Delayed wound healing occurred in 1 case, and secondary healing was obtained after treatment; primary healing of incision was achieved in the other patients. Postoperative X-ray films and CT images showed anatomic reduction of fracture and good position of internal fixation. All patients were followed up 14.6 months on average (range, 9-27 months). The range of motion of the affected ankle was close to the normal side at 6-8 weeks. The mean fracture healing time was 13.1 weeks (range, 11-17 weeks). Degenerative change of the ankle joint was observed in 3 cases (7.1%) with manifestation of mild narrowing of joint space on the X-ray films at last follow-up. According to Baird-Jackson score system, the results were excellent in 24 cases, good in 13 cases, and fair in 5 cases, with an excellent and good rate of 88%. ConclusionComputer-assisted surgical planning for ankle fractures can help surgeons identify type of ankle fractures and improve surgical scheme for guiding fracture reduction and selecting and placing implants, so good effectiveness can be obtained.

  • Comparison of effectiveness between plate and screw internal fixation in treatment of posterior malleolus fractures through posterolateral approach

    ObjectiveTo compare the effectiveness of posterior malleolus fractures treated by plate and screw internal fixation through posterolateral approach.MethodsThe clinical data of 95 patients with posterior malleolus fractures who were admitted between January 2016 and December 2019 and met the selection criteria were retrospectively analysed. They were divided into plate group (44 cases, treated with posterolateral plate internal fixation) and screw group (51 cases, treated with posterolateral screw internal fixation) according to different treatment methods. There was no significant difference in general data between the two groups of patients such as age, gender, cause of injury, side of injury, ankle fracture or injury classification, time from injury to operation, and percentage of posterior ankle fracture area to the distal tibia articular surface (P>0.05). The operation time, hospital stay, fracture healing time, and surgical complications were compared between the two groups. Imaging examinations (X-ray film, CT scan and reconstruction) were used to assess the reduction quality of ankle fracture, articular congruity, and re-displacement in ankle fracture. At last follow-up, the pain visual analogue scale (VAS) score was used to evaluate the patients’ pain, and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used to evaluate ankle joint function.ResultsPatients in both groups were followed up 6-30 months, with an average of 18.2 months. The operation time of the plate group was significantly longer than that of the screw group (U=−2.040, P=0.041); there was no significant difference in hospital stay between the two groups (U=−1.068, P=0.285). Incision swelling occurred in 2 cases in the plate group, sural nerve injury in 3 cases, and traumatic arthritis in 2 cases during follow-up. In the screw group, there were 1, 2, and 2 cases, respectively. The incidence of complications in the two groups (15.9% vs. 9.8%) was not significantly different (P=0.372). All patients who underwent tibiofibular screw fixation underwent the removal of the tibiofibular screw before taking full weight bearing at 12 weeks after operation, and there was no screw fracture and retention. During the follow-up, there was no infection, re-displacement of fracture, delayed bone union or nonunion, and there was no significant difference in fracture healing time between the two groups (t=0.345, P=0.731). There was no significant difference between the two groups of reduction quality of ankle fracture and articular congruity evaluation results (P>0.05). At last follow-up, there was no significant difference in VAS score, AOFAS ankle-hindfoot score and evaluation grade between the two groups (P>0.05).ConclusionBoth the plate and screw internal fixation through posterolateral approach can achieve satisfied effectiveness in the treatment of posterior ankle fractures with maintenance of fracture reduction, and recovery of ankle joint function. The screw internal fixation has the advantages of minimal invasion and shorter operation time.
