We have used this technique successfully for the treatment of type 1 and type 4 coronal shear fractures of the capitellum Fig.

在我们的工作中，成功地运用本方法对1型、4型肱骨小头冠状剪切骨折进行了处理（图1）。

If the capitellum is very comminuted, more

远端分离的程度要有限制，既能暴露肱骨小头，又要避免损伤环状韧带和骨间后神经。

Coronal shear fractures of the capitellum (types 1 and 4) are particularly difficult to treat because the entire fracture fragment is covered with articular cartilage, providing limited access for screw placement while trying to achieve stable fixation.

肱骨小头冠状剪切骨折（第1类和第4类）由于整个骨折片被软骨包括，用来完成固定的镙丝部位有限，故处理起来尤为棘手。

This design is to dials forks the components the processing craft and the jig design, its components are the forging, has the volume to be small, components complex characteristic,Because the surface is easier than the hole to process, when formulation technological process, first the machined surface, then processes other take the surface as the datum,In which various working procedures jig all uses the unit clamp, special regarding processes the big end of hole, the trough and drills the capitellum hole incline eyelet in the working procedure, Chooses locate mode which two sells at the same time, and operates the simple manual clamp way clamp, its organization design is simple, the convenience also can satisfy the request.

此次设计是对拨叉零件的加工工艺和夹具设计，其零件为锻件，具有体积小，零件复杂的特点，由于面比孔易加工，在制定工艺规程时，就先加工面，再以面为基准来加工其它，其中各工序夹具都采用专用夹具，特别的对于加工大头孔、槽和钻小头孔斜面小孔的工序中，选一面两销的定位方式，并以操作简单的手动夹紧方式夹紧，其机构设计简单，方便且能满足要求。

Objective To investigate the operative methods in children capitulum humeral fracture.

目的 探讨儿童肱骨小头骨折手术治疗的方法。

Methods To analyse the injury mechanism, operative methods, and follow-up results in 48 child cases of capitulum humeral fracture.

对48例肱骨小头骨折病例的损伤机制、手术方法、随访结果进行分析。

Results At 29 day,total mark of treatment group averages 84.87±7.88,improvement rate is 73.33%;Control group averages 71.78±11.73,improvement rate is 33.33%;After 16.63±4.54 month follow-up,prognosis of fracture is good,without occurrence of radius capitulum necrosis and ectopic ossification.

结果 第29天，治疗组总分平均84.87±7.88，优良率73.33%；对照组总分平均71.78±11.73，优良率33.33%；经16.63±4.54个月随访，骨折愈后良好，无桡骨小头坏死以及异位骨化的发生。

Digitaria has been traditionally divided on the nature of the spikelet hairs, which may be clavate, capitate, verrucose, or with crooked tips.

Digitaria在小穗毛的性质上传统上裂，可能是棍棒状，头状，瘤状，因为好放大被要求看这些特征，在总状花序上的小穗的集团是对鉴定的一个更实际的帮助。

The reverse force self-expansion rivet as one fastener part has one small head and one small-diameter neck in the root part as well as one integral expansion sheet with the same diameter as the shaft in between.

目前国内外所使用的《胀钉》是螺杆式的《他胀钉》，它构件多，成本高。因此，本人发明了简易的《反力自胀铆钉》来满足各种材料的铆制紧固上。其结构特点是在钉杆根部有直径偏小的颈部和小头，还在其间有与杆同径连体的胀片。
