数字化六轴外固定架和髓内钉固定治疗胫骨干骨折的回顾性对照研究

目的 对比分析数字化六轴（QSF）外固定架和髓内钉治疗胫骨干骨折的临床疗效。方法 采用回顾性病例对照研究分析2017年1月至2020年12月西安交通大学附属红会医院中西医结合骨科收治的98例胫骨干骨折病人的临床资料,其中男69例,女29例,年龄为（40.98±13.81）岁（16~71岁）。48例采用数字化六轴外固定架固定手术治疗（QSF外固定组）,50例采用髓内钉固定手术治疗（髓内钉组）,比较两组围手术期资料：手术时间、术中出血量、透视次数、下地负重时间等;其他随访及影像资料：完全负重时间、下肢功能量表（LEFS）评分、骨折愈合时间、骨折复位效果（术后成角及移位情况）、并发症等。结果 QSF外固定组病人均采用闭合复位骨折;髓内钉组有7例病人切开复位骨折,其余病人采用闭合复位骨折。所有病人均未发生血管神经损伤等严重并发症。病人随访（29.38±10.1）个月（12~44个月）。QSF外固定组手术时间、术中出血量、透视次数、下地负重时间、完全负重时间、骨折愈合时间、骨折复位质量显著优于髓内钉组（P＜0.05）;两组住院时间、切口愈合情况、膝关节屈曲活动度、踝关节跖屈活动度、踝关节背伸活动度的差异无统计学意义（P＞0.05）。在术后1年的末次随访中,QSF外固定组病人LEFS评分显著高于髓内钉组（P＜0.05）。结论 与髓内钉固定相比,QSF外固定架治疗胫骨干骨折创伤更小、复位效果好、开始及完全负重时间早、骨折愈合时间更短、取出简单。

Suprapatellar versus infrapatellar nailing for tibial shaft fractures: A comparison of surgical and clinical outcomes between two approaches

BackgroundTibial shaft fractures are a relatively common injury and contemporary treatment includes on-axis fixation with a locked intramedullary nail in the majority of cases. The conventional technique is via an infrapatellar approach but currently there is a trend towards the use of a suprapatellar approach. We compared key variables including operative time, radiation exposure and early patient reported outcomes when adopting a suprapatellar approach to tibial nailing in our unit versus our previous experience of infrapatellar tibial nailing.MethodTwenty-eight consecutive patients with tibial fracture underwent tibial nailing via the suprapatellar (SPN) approach. Six patients in the study group were excluded due polytrauma and need for dual orthopaedic and plastic surgery management. We compared outcomes with our most recent 20 consecutive patients who had undergone tibial nailing via an infrapatellar (IPN) approach. Primary surgical outcomes were: operative time, radiation exposure and accuracy of entry point of the nail on both anteroposterior and lateral radiographs. Clinical outcomes included time to weightbearing, time to radiographic union and patient-reported outcome score (Lysholm score).ResultsForty-eight consecutive patients underwent intramedullary nail fixation for tibial shaft fractures and 42 were eligible for inclusion in our study (22 SPN vs 20 IPN). There were no significant differences in patient demographics or injury patterns between the two groups. Operative time and radiation exposure were significantly lower in the SPN group when compared to the IPN group (115 min vs 139 min ± 12.5) (36 cGY/cm² vs 76.33 cGY/cm² +/- 20.1). Furthermore, patients in the SPN group reported superior outcome scores at a mean follow up of 3 months (8–24 weeks) There were no observed differences in complication rate between groups and time of final clinical follow up at a minimum of 6 months.ConclusionOur study shows that adoption of the SPN approach requires minimal learning curve, and has the potential benefits of reduced operative time, radiation exposure and superior patient reported outcomes when compared to the conventional infrapatellar approach.     

Implant fracture of the TFNA femoral nail

BackgroundThe TFNA (Trochanteric Fixation Nail Advanced) Proximal Femoral Nailing System (DePuy Synthes) is frequently used for intramedullary fixation of proximal femoral fractures. The aim of this study was to evaluate all TFNA implant fractures at a UK trauma unit to ascertain any patient or surgical factors associated with implant failure.MethodsA retrospective study was carried out identifying all patients that sustained a TFNA implant fracture over a five-year period. Data was collected on demographic information, ASA, co-morbidities, mechanism of injury, fracture pattern according to the AO/OTA classification, procedure details and time to failure. Radiographs were assessed by two independent reviewers to identify tip-apex distance (TAD), calcar TAD, reduction quality and union status at time of implant failure.ResultsSix cases were identified, all with implant breakage at the aperture for the proximal screw. All femoral fractures were intertrochanteric reverse obliquity type (OA/OTA 31A3). Two were traumatic fragility fractures and the remainder atraumatic. Mean time from index surgery to revision was 441 days (104–963). Mean TAD was 20.5 mm (15–24) and mean calcar TAD 24 mm (18–32). All six cases displayed radiographic non-union at the time of implant fracture.ConclusionPathological fractures resulting in reverse obliquity type fracture patterns and subsequent non-union appear to be contributory factors to TFNA breakage at the proximal screw aperture. This may be further exacerbated by alterations to the nail design from previous generations. In these patients, close follow up with clinical and radiographic surveillance should be employed. Further biomechanical and clinical studies are required to compare this finding against other nail designs.
