DHS和PFNA固定治疗老年股骨粗隆间骨折的疗效

目的对比动力髋螺钉(dynamic hip screw,DHS)治疗和股骨近端抗旋髓内钉(proximal femoral nail anti-rotation,PFNA)固定治疗老年股骨粗隆间骨折疗效。方法纳入本院收治的45例采用PFNA固定治疗的老年股骨粗隆间骨折患者作为研究组,研究时间为2017年11月-2018年11月;回顾性分析2016年11月-2017年11月在我院采用DHS治疗的45例老年股骨粗隆间骨折患者的临床资料,作为对照组。记录两组的相关手术指标,观察手术并发症情况。结果研究组的手术时间和骨折愈合时间均短于对照组,术中出血量明显少于对照组,术后疼痛VAS评分均明显低于对照组(P<0.05)。对照组的并发症发生率高于研究组(P<0.05)。结论PFNA固定治疗比DHS治疗老年股骨粗隆间骨折更加安全有效,值得临床借鉴和应用。     

Le syndrome de Klinefelter : une prédisposition au crime sexuel ?

BackgroundSeveral studies have reported over-representation of psychiatric disorders among patients with Klinefelter’ Syndrome (KS), with forensic complications.ObjectiveConsider determinants of sexual assault in patient with KS.ReviewIn this work, we present the case of Jules, 23 years old, with KS, benefiting from steroid replacement therapy, convicted of rape of a minor and evaluated in this context. We question here the role of his genetic pathology and of his hormonal treatment in this sexual assault.FindingsAccording to evidence from the literature, it is not possible to determine with certainty the fair value of each factor and their impact on the occurrence of the sexual criminal act. Indeed, although the crime rate among KS subjects is higher than in the general population, the majority of them have never been in trouble with the law; moreover, these subjects were no more likely to commit violent sexual acts than were criminals without KS. As for hormonal treatment, it seems that testosterone is better viewed as a facilitator of initiating an aggressive response than as a primary inductor.ConclusionIn conclusion, the onset of sexual violence that accompanied the introduction of hormonal treatment into a patient with KS suggests an effective involvement of steroid replacement therapy, even small, in the criminal act. This must incite clinicians to extreme prudence and to take account of multidisciplinary expertise (psychiatrist, endocrinologist) in order to reconsider the continuation of the treatment in this particular forensic context. Finally, we discuss other factors that can precipitate such a violent act.     

肱骨骨不连的手术治疗

目的探讨肱骨骨不连的手术治疗方法及疗效。方法1998年12月～2005年5月共收治肱骨骨不连患者25例,均为肱骨骨折内固定术后发生骨不连,其中3例并发骨髓炎,6例合并不同程度肱骨骨缺损,骨缺损长度为3～6cm。骨不连病程8个月～5年。15例行吻合血管游离腓骨移植,10例采用加压交锁髓内针进行肱骨固定并辅以自体骨植骨。结果术后25例均得到随访,时间6个月～6年2个月。吻合血管游离腓骨移植组中移植的腓骨段均与肱骨干形成骨性愈合,平均骨性愈合时间为3．1个月；交锁髓内针组平均骨愈合时间为3．8个月。按Crates和Whittle肩肘关节功能评价标准,腓骨移植组：优9例,良4例,差2例；交锁髓内针组：优5例,良3例,差2例。结论应用加压交锁髓内针辅以自体骨移植对硬化性肱骨骨不连是一种有效的外科治疗方法；对合并骨髓炎、大段骨缺损及严重骨质疏松的肱骨骨不连,采用吻合血管游离腓骨移植可一期进行修复与重建。     

下肢复杂骨折交锁髓内钉治疗粉碎骨折螺钉辅助固定的意义

[目的]探索在交锁髓内钉治疗下肢复杂骨折中粉碎骨折块辅助固定的意义。[方法]下肢复杂骨折78例根据AO分型均为C型骨折，通过交锁髓内钉内固定，辅以拉力螺钉固定。[结果]术后摄片骨折及骨折块达解剖或功能复位，随诊6～24个月，优良率为94．88％（74／78例）。[结论]四肢复杂骨折治疗中，粉碎骨折块的螺钉辅助固定能够加强交锁髓内钉的稳定性，减少断钉、断棒现象，有利于骨折愈合。     

股骨重建钉在股骨粗隆下骨折手术中的应用

[目的]探讨股骨重建钉（RIN）治疗股骨粗隆下骨折（SFF）的手术方法及临床疗效。[方法]1998年6月-2005年5月，采用RIN技术对4JD例SFF患者进行固定，其中男27例，女13例；年龄22．．75岁。平均43．5岁。依据Seinsheimer分类：Ⅱ型5例，Ⅲ型13例，Ⅳ型21例，Ⅴ型1例。高能量损伤33例，低能量损伤7例。开放性骨折3例。[结果]4JD例随访8个月-2a6个月，平均1a8个月。X线片观察骨折愈合时间4．2月（3．2-6．5月）。按照韩一生评分标准，优26例，良12例，可2例，优良率95％。无感染、内固定失效、畸形愈合及股骨头缺血性坏死等并发症。[结论]RIN技术是治疗SFF的一种有效方法，具有固定可靠、并发症少、骨折愈合率高等优点。精细的手术操作是手术成功的关键。     

Nails in systemic disease

Nail plate and nail unit abnormalities may be helpful as diagnostic tools or as a part of the puzzle for confirmation of systemic disease. There are specific and nonspecific nail signs, which can be seen involving one or more nails, that occur simultaneously or secondary to systemic disease. Occasionally these clues can be diagnostic, while most are nonspecific reaction patterns. Nail changes occur in the nail plate as a result of nail matrix abnormalities caused by systemic disease and other systemic insults such as reactions to medications. In this article we review some of the more common nail signs that can be used to help diagnose systemic disease.

Biology and Biomechanics in Osteosynthesis of Proximal Humerus Fractures

Abstract Surgical treatment of proximal humeral fractures still remains a challenge. This is primarily due to the fact that sufficient implant fixation in humeral head fractures is often not achieved due to substantial bone tissue loss with increasing age. In the last few years the locking plates and locking nails have been introduced into clinical practice with varying results. The biomechanical studies have focused on locking plate osteosynthesis as well. The following paper focuses on bone quality, biomechanical studies and biology of proper osteosynthesis and reviews the most recent literature.     

Acro-pectoro-renal field defect with contralateral ureteropelvic junction obstruction

Ureteropelvic junction obstruction was noted in a newborn male infant with acro-pectoro-renal field defect. To our knowledge, this association has not previously been reported. Ultrasonography of the urinary tract should be performed on all children with aplasia of the pectoralis major muscle.
