Knowledge of the size and shape of radial head is essential for construction of radial head prosthesis. Further, the measurements of bicipital tuberosity and its angular relationship to radial head are significant in surgical techniques, like in the reconstruction of biceps tendon. Even the morphometry of the distal radius is significant in numerous clinical orthopedic situations such as reduction of distal radius fractures and in the design of distal radius prosthesis. So, the aim of the study was to determine the morphometric parameters of proximal and distal radius in dry adult Indian radius.
Fifty intact adult Indian radius (right = 23, left = 27) were chosen, and the various parameters of proximal and distal ends of radius were studied. Student's t-test was done to correlate all these parameters on the right and left sides.
The mean length of radius, height of head at medial and lateral ends, head anteroposterior and transverse diameter, head thickness at ventral, dorsal, and lateral ends were 23.5, 0.90, 0.75, 1.91, 1.85, 0.42, 0.32, and 0.30 cm, respectively. The mean depth of articular facet, length of neck, proximal and distal neck diameter, width and length of bicipital tuberosity, and radial circumference at bicipital tuberosity were 0.19, 1.19, 1.36, 1.31, 1.23, 1.97, and 4.54 cm, respectively. The mean length of styloid process, oblique and transverse width of lower end, anteroposterior diameter of lower end, and angle of radial inclination were 0.98cm, 2. 81cm, 2.59cm, 1.86cm, and 25.05°, respectively.
This study will be useful for orthopedic surgeons in making prosthesis for the proximal and distal ends of radius.
了解桡骨头的大小和形状对于桡骨头假体的构建至关重要。此外，肱二头肌结节的测量及其与桡骨头的角度关系在手术技术中具有重要意义，如在肱二头肌肌腱重建中。甚至桡骨远端的形态测量在许多临床骨科情况中也很重要，如桡骨远端骨折的复位以及桡骨远端假体的设计。因此，本研究的目的是确定干燥的成年印度人桡骨近端和远端的形态学参数。
选取50例完整的成年印度人桡骨（右侧23例，左侧27例），研究桡骨近端和远端的各种参数。采用学生t检验对左右两侧的所有这些参数进行相关性分析。
桡骨的平均长度、内侧和外侧端的头部高度、头部前后径和横径、腹侧、背侧和外侧端的头部厚度分别为23.5、0.90、0.75、1.91、1.85、0.42、0.32和0.30cm。关节面的平均深度、颈部长度、近端和远端颈部直径、肱二头肌结节的宽度和长度以及肱二头肌结节处的桡骨周长分别为0.19、1.19、1.36、1.31、1.23、1.97和4.54cm。茎突的平均长度、下端的斜向和横向宽度、下端的前后径以及桡骨倾斜角分别为0.98cm、2.81cm、2.59cm、1.86cm和25.05°。
本研究将有助于骨科医生制作桡骨近端和远端的假体。
