Long-term Clinical and Radiological Outcomes of Kirschner Tension Band Fixation versus Clavicular Hook Plate for RockwoodⅢ Acromioclavicular Joint Dislocation

目的　比较克氏针张力带与锁骨钩钢板治疗RockwoodⅢ型肩锁关节脱位的临床疗效。 方法　1999年1月－2007年3月，收治肩锁关节脱位患者29例，分别采用克氏针张力带联合喙锁韧带重建（克氏针组10例）和锁骨钩钢板（钢板组19例）治疗。其中男18例，女11例；年龄19～50岁，平均38.2岁。患者均为新鲜RockwoodⅢ型肩锁关节脱位，受伤至手术时间1～16 d，平均3 d。两组患者性别、年龄、受伤至手术时间等一般资料比较差异无统计学意义（P＞0.05）。进行两组患者术后临床及影像学评估比较。 结果　25例患者（克氏针组10例，钢板组15例）获随访，随访时间2～12年，平均6年。术后克氏针组发生克氏针弯曲5例、断裂1例；钢板组切口浅表感染2例，经换药后治愈，其余患者切口Ⅰ期愈合。两组患者肩锁关节均获得良好功能，组间比较差异无统计学意义（P＞0.05）。影像学方面：与克氏针组相比，在患肢负重位时钢板组喙锁间隙间距增加了23%（P＜0.05），非负重位两组间距差异无统计学意义（P＞0.05）。术后8～12周出现喙锁韧带钙化，钢板组12例、克氏针组2例（P＜0.05）。术后6个月出现肩锁关节骨性关节炎，钢板组2例、克氏针组1例（P＞0.05）。肩关节功能与影像学结果无相关性（r=0.096，P＞0.05）。 结论　克氏针张力带联合喙锁韧带重建和锁骨钩钢板固定治疗RockwoodⅢ型肩锁关节脱位均可获得良好的临床功能。与克氏针张力带相比，锁骨钩钢板固定具有手术操作简便、疗效确切、并发症少、能够早期康复锻炼等优点。

TISSUE FLAP TRANSFERRING FOR WOUND REPAIR OF THE CLAVICLE

Objective To investigate the result of tissue flap transferring for wound repair of the clavicle. Methods From 1994 to 2000, 3 patients( 1 withclavicle osteosynthesis, 1 with chronic clavicle osteomyelitis, and 1 with radioactive ulcer in clavicular region accompanied by chronic osteomyelitis of clavicle) were reconstructed with turnover adipofascial flap, myocutaneous flap of pectoris, and myocutaneous flap of latissimus dorsal respectively. The outcome was observed. The operation principles of tissue flaps transferring for wound repair of the clavicle were summarized. Results Follow-ups were done for 2 months to 7 years. All tissue flaps survived well and the wounds in clavicular region were healed well. There was no recurrence of chronic clavicle osteomyelitis. Conclusion Turnover adipofascial flap, myocutaneous flap of pectoris and latissimus dorsal are often used for wound repair of theclavicle. Most of the wounds of the clavicle can be repaired by turnover adipofascial flap. Myocutaneous flap of pectoris and latissimus dorsal are more suitablefor wound repair with chronic clavicle osteomyelitis. In the case of radioactive ulcer of the clavicular region, myocutaneous flap of latissimus dorsal transposition is a better alternative for wound repair.

锁骨钩钢板固定结合喙锁韧带重建治疗陈旧性肩锁关节脱位

目的 总结锁骨钩钢板固定结合喙锁韧带重建治疗陈旧性肩锁关节脱位的临床疗效。 方法 2003 年6 月－ 2008 年12 月，采用锁骨钩钢板固定结合喙锁韧带重建治疗17 例陈旧性肩锁关节脱位。男11 例，女6 例；年龄16 ～ 53 岁，平均39 岁。均为直接暴力致伤。左侧7 例，右侧10 例。Rockwood 分型：Ⅲ型14 例，Ⅳ型2 例，Ⅴ型1 例。受伤至手术时间为14 ～ 55 d，平均23 d。 结果 术后切口均Ⅰ期愈合。肩锁关节脱位均纠正，无神经、血管损伤等并发症发生。术后患者均获随访，随访时间6 ～ 15 个月，平均12 个月。术后3 ～ 6 个月取出锁骨钩钢板，无再脱位发生。术后6 个月按Karlsson 疗效评价标准：优12 例，良4 例，差1 例，优良率94.1%。 结论 锁骨钩钢板固定结合喙锁韧带重建具有操作简便、创伤小、固定可靠、可早期功能锻炼等优点，是治疗陈旧性肩锁关节脱位的一种有效方法。

ANALYSES OF EPIDEMIOLOGY IN 363 CASES OF CLAVICLE FRACTURES

Objective To analyze the epidemiological features of clavicle fractures.Methods A total of 363 cases of clavicle fractures were treated from February 1993 to November 2002, their case history data were reviewed and evaluated by epidemiological method.Results Out of 363 cases, there were 269 males and 94 females, aged from new born to 96 years. The locations of fractures were on left side in 159 cases and on right side in 204 cases. Neonatal clavicle fracture occurred in the case of delivery (0.28%). The causes of disease for adult clavicle fractures were traffic injury (52.1%) and daily falling injury(31.1%). There were232 cases of simple fractures and 131 cases of comminuted fractures. The fracture positions included inner(6 cases), middle(328 cases) and outer parts(29 cases). Multiinjuries occurred in 78 cases, the rib fractures concomitant with clavicle fractures were the commonest(31 cases).Conclusion The clavicle fractures are the common injury. Of them, traffic injury and daily falling injury arethe most common. The rib fractures are always accompanied with clavicle fractures.The main position of fracture is on the middle part.

EFFECTIVENESS OF T-LOCKING PLATE FOR INTERNAL FIXATION OF MEDIAL CLAVICLE FRACTURE

To investigate the effectiveness of T-locking plate in treating medial clavicle fracture so as to find out a therapy with safety and stabil ity. Methods Between October 2006 and January 2009, 13 patients with medial clavicle fracture were treated with open reduction and T-locking plate fixation. There were 9 males and 4 females, aged 18-68 years (mean, 47 years), including 7 cases of traffic accident injury, 4 cases of fall ing injury from height, and 2 cases of heavy object hit injury. The locations were left side in 5 cases and right side in 8 cases. All cases were closed fracture. The disease duration was 1 hour to 14 days. Results All incisions healed by first intention after operation. The X-ray films showed good reduction of fracture and internal fixation. All the 13 patients were followed up 12-18 months (mean, 15 months). The average fracture heal ing duration was 8 weeks (range, 6-12 weeks). No compl ication of infection, nerve or blood vessel injury, hemopneumothorax, or internal fixation loosening or failure occurred. The anatomical medial clavicle structure as well asappearances and functions were restored. According to Rockwood’s score method, the results were excellent in 11 cases and good in 2 cases. Conclusion The internal fixation of T-locking plate in treating medial clavicle fracture has the advantages of good stabil ity and low risk. Besides, the patients can do functional exercises early and the shoulder joint function can be improved in great degree.

Effectiveness of in vitro fenestration versus bypass surgery for type B aortic dissection involving the left subclavian artery

ObjectiveTo analyze the effectiveness of in vitro fenestration versus bypass surgery techniques in the treatment of type B aortic dissection involving the left subclavian artery by thoracic endovascular aortic repair (TEVAR).MethodsAmong the 53 patients with type B aortic dissection involving the left subclavian artery admitted to our center from January 2017 to October 2020, 23 underwent in vitro fenestration + TEVAR (a fenestration group with 18 males and 5 females aged 53.6±5.3 years), and 30 patients underwent left common carotid artery-left subclavian artery bypass + TEVAR (a bypass group with 24 males and 6 females aged 51.8±3.8 years). The effectiveness and safety between the two groups were compared.ResultsThe surgical success rate was 100.0% in both groups. And there was no death within postoperative 30 days and during the follow-up. There was no endoleak immediately postoperatively and during 1-year follow-up in the two groups. The operation time and hospitalization expenses in the fenestration group was less or shorter than those in the bypass group (P<0.05). The reduction in blood pressure of the left upper limb in the fenestration group was greater than that in the bypass group (P<0.05). There was no symptom of left upper limb ischemia, dizziness or hoarseness in both groups.ConclusionThe two methods of reconstruction of the left subclavian artery are safe and effective. In vitro fenestration can reduce surgical trauma and costs, and bypass surgery can provide better forward blood flow for the left subclavian artery.
