老年人股骨粗隆间骨折手术时机对预后影响的临床研究

目的：探讨老年股骨粗隆间骨折手术时机对临床预后结局的影响。方法整群选取2015年1月—2016年1月该院收治的老年股骨粗隆间骨折患者68例为研究对象。根据患者手术时间将其分为A组与B组, A组32例,B组36例,观察两组患者不同年龄术后30 d、1年的死亡情况。结果两组患者术后30d、1年死亡率比较差异无统计学意义,P>0.05；但A组、B组患者中超过80岁的患者术后1年死亡率明显低于80岁以下年龄患者,P<0.05,差异具有统计学意义。结论年龄超过80岁的老年股骨粗隆间骨折患者术后1年死亡率相对较高。     

Primary epidural lumbar Ewing sarcoma presenting as cauda equina syndrome in an adult patient who underwent surgical decompression: A case report

Ewing sarcoma (ES) is a rare primary neoplasm in the lumbar adult spine and may mimic a benign tumor. In this case, after a patient's three-month history of lower back pain and rapidly progressing leg numbness and weakness, magnetic resonance imaging (MRI) showed a mass in the third lumbar vertebra. At a two-month follow-up, imaging showed a fracture, compression and lesion enlargement. Decompression and fixation confirmed ES, and the patient began combined radiotherapy and chemotherapy. Two months postoperatively, residual ES was suspected on MRI. The patient underwent a second surgery, and histopathology confirmed necrosis. A six-month follow-up after the first surgery showed no tumor recurrence. This case supports the inclusion of ES in the differential diagnosis of pathologic spinal fracture. Early decompression and spinal fixation are critical for preserving neurologic and spinal functions in ES complicated by a compression fracture. Combined adjuvant radiotherapy and chemotherapy remain the standard therapeutic strategy.     

CT三维重建模型下模拟髋臼前柱2种经皮置钉方法的比较

目的对比CT三维重建模型下模拟髋臼前柱2种经皮置钉方法的效果。方法选取55例正常成人骨盆CT资料构建三维模型,共110侧髋臼前柱,调整模型透明度使其类似常规X线片,分别用2种置钉方法进行置钉,A组利用出口闭孔位和入口髂骨位引导置钉,B组利用髋臼前柱轴位引导置钉,置钉完成后恢复图像为不透明状态,记录螺钉是否进入髋关节及与耻骨支的位置关系。结果55例110侧髋臼,4侧未能找到髋臼前柱轴位影像予以剔除,106侧髋臼前柱纳入研究。2组模型均无螺钉进入髋臼。A组螺钉置入优秀、良好、尚可率分别为59.4%、17.0%、23.6%,B组分别为59.4%、22.6%、17.9%,2组总体置钉质量差异无统计学意义(Z=-0.829,P=0.407)。A组女性骨盆置钉优秀、良好、尚可率分别为7.1%、21.4%、71.4%,B组分别为28.6%、21.4%、50.0%,B组置钉质量显著高于A组(Z=-3.000,P=0.003)。A组男性骨盆置钉优秀率78.2%,良好率15.4%,尚可率6.4%,B组分别为70.5%、23.1%、6.4%,2组差异无显著性(Z=-0.969,P=0.333)。结论髋臼前柱轴位可以作为引导置钉的一种手段,尤其适用于女性患者,对于男性患者,2种方法均可实现较好的置钉。     

A systematic review of combined pelvic and acetabular injuries

PurposeInjuries of both pelvic ring and acetabulum as rare very few articles are available in literature. There are no set protocols in defining the injury let alone defining early and definitive management strategies. This article is an attempt to encompass all available data to give us guidelines in managing these injuries.MethodsAn extensive literature review was carried out on PubMed/Medline, google scholar and Embase databases was done with the eligibility criteria of 1) Case series with a minimum of 20 cases. 2) The patient’s outcome reported. 3) Full article available. 4) Article in English. 5) Minimum Jadad score of 3. As per PRISMA guidelines the search was done and gradually filtered down to relevant articles which were 8 in number.ResultsThe incidence of these injuries range from 5 to 16%. The transverse acetabular fracture pattern is the commonest followed by associated both column fractures. There is equal propensity of Anteroposterior compression and lateral compression injuries. The injury mechanism appears to transmitted lateral force from the greater trochanter inwards with an implosion injury causing acetabular and pelvic injury as a continuum. The initial management is similar to managing pelvic ring injuries with focus on patient resuscitation, hemodynamic stabilization and temporary stabilization. The injury severity score and the mortality rates are comparable to isolated unstable pelvic ring injuries. Definitive management focuses on fixing the posterior pelvic ring first followed by the acetabular fracture and then the anterior pelvic ring. The displacement rates and outcome is worse than isolated acetabular injuries or pelvic injuries.ConclusionCombined Pelvic and acetabular injuries are complex injuries which need to be managed initially as we manage pelvic injury and later as we fix as an acetabular fracture meticulously.     

Conjunctival flap advancement with or without scleral graft for hypotony maculopathy after trabeculectomy

AIM: To introduce a novel technique for transscleral fixation of the PC-IOL that requires no sutures on the IOL haptics. METHODS: Instead of suturing polypropylene onto the IOL haptics, the method simply winds the thread on the haptics. Fifteen eyes of 15 patients underwent this technique and were followed up for more than 18 months. Surgical outcomes and post-operative complications were evaluated and compared with those of the conventional transscleral fixation method. RESULTS: Postoperative cylinder was significantly lower in the thread winding group than in the conventional transscleral fixation method group (-1.02±0.46 diopters vs -1.57±0.77 diopters; P=0.01). Further, no postoperative complications, such as optic capture, IOL dislocation, and hyphema, were detected in the thread winding group. CONCLUSION: We believe that our thread winding technique is better than previously reported methods because it is simple, mechanically stable, and free from suture-related complications.     

Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis

ObjectiveMultiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients.MethodsMeta-analysis of 21 studies of 430 acetabular fractures with mean follow-up of 44 months (range, 17−97 months). Two independent researchers searched and evaluated the databases of Ovid, Embase, and United States National Library of Medicine using a Boolean search string up to December 2019. Population demographics and complications, including presence of heterotopic ossification (HO), dislocation, infection, revision rate, neurological deficits, and venous thromboembolic event (VTE), were recorded and analyzed.ResultsWeighted mean Harris Hip Score was 83.3 points, and 20% of the patients had reported complications. The most common complication was HO, with a rate of 19.5%. Brooker grade III and IV HO rates were lower at 6.8%. Hip dislocation occurred at a rate of 6.1%, 4.1% of patients developed VTE, deep infection occurred in 3.8%, and neurological complications occurred in 1.9%. Although the revision rate was described in most studies, we were unable to perform a survival analysis because the time to each revision was described in only a few studies. The revision rate was 4.3%.ConclusionsAcute THA is a viable option for treatment of acetabular fracture and can result in acceptable clinical outcomes and survivorship rates in older patients but with an associated complication rate of approximately 20%. Considering the limited treatment options, THA might be a viable alternative for appropriately selected patients.     

浮肩损伤的临床特征和治疗

目的 总结浮肩损伤（floating shoulder injury，FSI）的临床特征和治疗效果。方法1993年1月-2004年9月收治浮肩损伤患者8例，除2例行锁骨固定带固定外，其余6例均行手术治疗，其中单纯行锁骨切开复位重建钢板内固定1例，同时行肩胛骨内固定5例。受伤至手术时间为2h～7d，平均3．5d，术后6个月对患肩功能进行Constant评分判定疗效，并对浮肩损伤的临床特征和治疗进行总结。结果6例患者经过6个月～3年（平均11个月）的随访，锁骨和肩胛骨骨折均愈合，肩关节活动范围无明显受限，但有2例患者在举重物时肩关节有轻度的疼痛，1例患侧上肢肌力较对侧稍减弱。术后6个月患肩功能Constant评分平均为93分。结论浮肩损伤多为高能量暴力所致的不稳定性肩胛带损伤，在治疗方案上尚存争议。但对移位明显的浮肩损伤以及有伴发伤的浮肩损伤进行手术治疗是必要的。
