头状骨

Results Early signs of ANFH using CT showed that, in 26 femoral heads in 21 cases, there were radiate star shape of high-density osteosclerosis of the trabeculae in 8 femoral head.

结果 CT早期表现：2 1例 2 6个股骨头，其中 8个股骨头骨小梁呈放射状密度增高的"星状征"，骨小梁境界清楚、锐利属Ⅰ期；18个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属Ⅱ期；并有 3个股头在Ⅱ期影像改变基础上出现软骨下骨折及轻微塌陷，属Ⅲ期。

Methods:Fifty paired embalmed cadaveric humeri (twenty-five pairs:fourteen from male donors and eleven from female donors) were scanned in medial-lateral and anterior-posterior position according to the humeral retroversion by CT. Images of the humeri in the transverse planes at the lowest border of neck,20mm and 40mm distal of LBN(LBN-20、LBN-40), isthmus, head-neck anterior-posteriorwere obtained. Sixty-one extracortical and intracortical parameters were measured exactly by image analytic computer software that included offset, head position, head-shaft angle, head to tuberosity height, head thickness, curvature radius, articular surface arc, neck diameter, isthmus position, proximal and distal border of isthmus, maximum coronal and sagittal diameter of medullary canal and thickness of cortical bone in four planes, including LBN, LBN-20,LBN-40 and isthmus.

50根成对防腐肱骨(男14对，女11对)按肱骨头扭转角置于冠状位和矢状位，行肱骨全长，头颈矢状面，解剖颈下缘及其下20mm、40mm，髓腔狭窄部四平面CT扫描，由CT软件测量冠、矢状位髓腔内外参数共61项，包括头心—干轴距，头位置，头干角，头—结节高度差，头厚度，头半径，关节面张角，解剖颈直径，髓腔狭窄部位置，解剖颈下缘及其下20mm、40mm和狭窄部四个平面髓腔的最大冠、矢状径，皮质骨厚度等。

At the front of their bulbous blue heads they have curved fangs that act as jaws.

在他们蓝色球根状的头前面有一个弧形状的牙，那个就是颌骨。

The maxillary processes extend in a cephalad direction form the piriform aperture to the lacrimal crest, uniting with the frontal and nasal bones.

上颌骨额突由梨状孔和泪嵴向头侧方向伸出，与额骨和鼻骨相接。

The radial head was excised and was not replaced, and the fixation of the coronoid fragment was unsuccessful.

桡骨头被切除，没有置换，冠状突骨块固定失败。

This includes (1) fixation or replacement of the radial head,(2) fixation of the coronoid fragment,(3) repair of the lateral collateral ligament complex, and (4) repair of the medial collateral ligament and/or application of a hinged external fixator for patients who demonstrate residual instability.

该方法包括：桡骨头复位或置换，冠状突骨块的复位，侧副韧带的修复以及修复内侧副韧带或对些肘关节不稳定的患者应用外固定架。

Enlarged and globular at the tip, as a bone of the wrist having a rounded, knoblike end .

头状的一端增大的和球状的，如手腕的带有圆形球状末端的骨

Methods: Proximal row carpectomy were performed on 12 formalin-fixed cadaver hand specimens. The anatomic features and the movement of new radio-capitate joint were observed. The distal row carpal bones and the distal radius and ulnae were longitudinally and transversely dissected to observe their joint curves and contact match.

12例福尔马林固定的尸体手标本，行近侧列腕骨切除术后观测头状骨近端关节面的解剖学特点和活动；纵、横行剖开远侧列腕骨和桡尺远端，描模正常桡骨－月骨关节面和桡尺骨－头状骨关节面的匹配曲线。

The temporomandibular joint is assessed by looking for jaw deviation during opening and by palpating the head of the condyle, anterior to the ear.

颞下颌关节的检查为当开口时在耳前方扪诊髁状突的头，检视颌骨的偏向。

There are significant anatomical differences between the radio-capitate joint and the normal wrist joint.

头状骨近端和桡尺骨远端形成的关节面其解剖学上明显不同于正常腕关节。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
