目的 回顾分析不同内固定方式对老年股骨粗隆间骨折的临床疗效。 方法 1999年3月－2009年5月采用内固定手术治疗121例股骨粗隆间骨折患者，根据内固定方式不同分为4组：动力髋螺钉（DHS；A组43例）、经皮加压钢板（PCCP；B组19例）、股骨近端髓内钉（PFN；C组27例）、Gamma钉（D组32例）。4组患者年龄、骨折类型（Tronzo-Evans分型）等一般资料比较差异无统计学意义（P＞0.05），具有可比性。记录手术时间、术中出血量及术后引流量、术中术后并发症、骨折临床愈合时间、术后髋关节功能恢复程度，比较评价各组临床疗效。 结果 术后各组患者切口均Ⅰ期愈合，无伤口感染等早期并发症发生。患者均获随访，随访时间18～108个月，平均56.4个月。与A组比较，B、C、D组手术时间明显缩短，术中出血量及术后引流量减少，骨折愈合时间缩短，差异均有统计学意义（P＜0.01），A组较差；B、C、D各组间两两比较差异无统计学意义（P＞0.05）。术后并发症发生率A组较高，与其余各组比较差异有统计学意义（P＜0.05）。末次随访时各组髋关节功能Harris评分比较差异无统计学意义（P＞0.05）。 结论 B、D组及C组3种手术方法在治疗老年患者股骨粗隆间骨折具有创伤小、并发症少等优势，与A组法比较更有利于老年患者术后康复，但应注意骨折的良好复位及内固定物位置。
Objective To summarize the cl inical characteristics of 596 patients with fracture in Wenchuan earthquake and to investigate the therapeutic methods and effects of early treatment. Methods From May 12th 2008 to May 21st 2008, 596 patients with fracture caused by Wenchuan earthquake were treated, including 283 males and 313 females aged1.9-102 years (median 43 years). The time from injury to hospital ization varied from 12 minutes to 4 days. There were 132 cases of upper extremity fracture, 496 cases lower extremity fracture, 10 cases clavicular fracture, 16 cases scapular fracture, 23 cases pelvis fracture, and 59 cases spinal fracture. Among them, 183 cases were open fracture and 413 cases were closed fracture. And 214 cases had multiple fracture (35.9%) and 68 cases had crush injury in l imbs which scored (6.84 ± 2.48) points according to the mangled extremity severity score (MESS). Thirty-six cases were combined with neurovascular injury. The wound of the open fracture was contaminated at different degrees, but no gas gangrene was observed. Open fracture was treated with suturing or no suturing after debridement, open reduction and internal or external fixation. Closed fracture was fixed with spl ints, cast and traction. Forty-nine patients whom were highly suspected as osseous fascia compartment syndrome received incision decompression timely, and 34 patients whose MESS were above 7.0 points or suffering from crush injury of l ifethreatening systemic symptoms received amputation. Results Apart from 34 patients receiving amputation, 460 patients achieved functional reduction of fracture after manipulative reduction and 102 cases got satisfactory reduction after surgery. Postoperatively, 289 patients were transferred to other hospitals. Among the rest 307 patients, 34 with severe wound infection were healed after multiple debridement, anti-infection, and skin flap transplantation (16 cases healed by first intention and 18 cases healed by second intention), 42 cases with crush syndrome were treated with open decompression and amputation, and nodeep venous thrombosis of lower l imb, stress ulcer and death were observed after operation (29 cases healed by first intention and 13 cases healed by second intention). Conclusion By aiming at the features of fracture caused by earthquake, the prompt and professional treatment can achieve good therapeutic effects.
