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。     

新生儿骨矿质含量及影响因素的研究

应用双光子及单光子吸收测定技术，检测了９２名出生３ｄ内的新生儿骨矿质含量，其中巨大儿３０名，正常体重儿３２名，低出生体重儿３０名，其孕龄分别是４０．１±０．７、３９．１±１．５和３７．４±１．２孕周。结果表明，巨大儿、正常体重儿、低出生体重儿的全身骨矿质含量分别是１０１．６±２８．８、８５．２±１９．８、５９．９±２７．２ｇ／ｃｍ２，巨大儿骨矿质含量最高，正常体重儿次之，低出生体重儿最低，差异有显著性（Ｐ＜０．０１）。颅骨、肱骨、股骨的骨矿质含量与全身的骨矿质含量有高度的相关性，相关系数分别是０．９４３、０．８７９和０．７４５（Ｐ＜０．０１）。全身的骨矿质含量与出生体重、孕龄及头围有高度相关性，相关系数分别是０．７５５、０．５９６和０．５５６（Ｐ＜０．０１）。提示颅骨、肱骨及股骨的任一部位均可代表全身的骨矿质含量，肱骨是确定全身骨矿质含量较好的部位，新生儿骨矿质含量受出生体重、孕龄及头围的影响较大。

腋神经和桡神经与肱骨的关系及其临床意义

目的　观测腋神经、桡神经与肱骨骨性标志的关系 ,为肱骨手术或外固定提供帮助。方法　在 30例 6 0侧成人上肢标本上观、测了腋神经、桡神经与肱骨有关骨性标志的距离。结果　肱骨最大长 (30 6 6 5± 17 4 8)mm ;肱骨最近端到腋神经(5 8 10± 5 6 1)mm ;肱骨最近端到桡神经穿外侧肌间隔处 (177 75± 11 86 )mm ;解剖颈最低点到腋神经 (16 2 4± 2 78)mm ;肱骨最近端到肱骨肌管入口处 (118 4 9± 6 6 1)mm ;并测量计算了各段占肱骨最大长的比例。结论　腋神经在肱骨近端 1/ 5处容易受损 ,而桡神经在肱骨下 3/ 5段为易损伤部。从术前和术中的影像 ,能测量和计算出神经的基本位置 ,可减少或避免神经损伤     

High Velocity Gunshot Fractures of Humerus: Results of Primary Plate Osteosynthesis

BackgroundHigh velocity gunshot fractures usually seen in conflict zones, often mandate external fixation due to delayed presentation and associated contamination. In the presented observational study, we managed high velocity gunshot fractures of humerus with adequate debridement and primary plate osteosynthesis under controlled conditions with gratifying results.Material and MethodsEighteen consecutive cases of fracture of the humerus secondary to high velocity gunshot wounds with ages ranging from 28 to 45 years reporting within 6 h of the initial injury formed our study group. Immediate debridement, lavage and primary plate osteosynthesis was carried out following hemodynamic stabilisation and intravenous antibiotics. All the cases were followed up at 2, 4, 6 months, 1 year and then annual follow-up including telephonic follow-up for six patients.ResultsFifteen cases of Gustillo Anderson type III A, two of type III B and one of type III C were managed with primary plate osteosynthesis. Brachial artery injury was addressed immediately, however injured radial nerve ends were tagged. Five cases showed delayed/non-union and were managed with decortication and autologous bone grafting. Two cases of deep infection could be managed with implant retention till union. The implants were removed following fracture consolidation. All the fractures united and no patient was left with sequelae of chronic infection.ConclusionTimely presentation of high velocity gunshot fractures of humerus teamed up with adequate debridement, soft tissue management and primary plate osteosynthesis can offer satisfactory outcomes. Associated vascular injury needs immediate attention. Nerve injuries can be addressed in a staged procedure. Our results have been satisfactory and add to the scant literature available on the subject, however further studies are warranted.     

Treatment of solitary cysts of the humerus

Summary The classical surgical treatment of unicameral bone cysts of the humerus with curettage and bone grafting is unreliable with approximately 40% failure rate. The author describes a technique of subperiosteal diaphyseal and metaphyseal resection and replacement with a section of fibula maintained in position with an intramedullary nail and further supported by massive tibial cortical and cancellous grafting. Consistent incorporation of the graft and excellent remodelling were observed in 36 patients so treated. No complications or recurrence were reported.

Résumé Le traitement chirurgical «classique» des kystes solitaires de l'humérus par curettage et greffe osseuse ne donne pas des résultats constants, puisqu'il comporte environ 40% d'échecs. L'auteur décrit une technique de résection sous-périostée, diaphysaire et métaphysaire, avec remplacement par un fragment de péroné maintenu par enclouage centro-médullaire et complété par des greffons tibiaux cortico-spongieux. Une parfaite incorporation de la greffe et un excellent remodelage ont été obtenus dans les 36 cas traités de cette manière. Il n'y a eu ni complications, ni récidives.
