A morphological and morphometric study of proximal and distal ends of dry radii with its clinical implications

Abstract

R adial head and neck fractures constitute 1.7-5.4% of all fractures. Radial head fractures alone constitute one-third of all elbow fractures and about 20% of all elbow trauma cases.[1] An appreciation of the part played by radial head in the overall stability of elbow and forearm has encouraged several investigators to recommend conservation of radial head, either by operative fixation or by prosthetic replacement.Distal radius fractures comprise 8-15% of all upper limb fractures. So, information of normal values of distal Background: 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. Methods: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. Results: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 25.05º, respectively. Conclusion: This study will be useful for orthopedic surgeons in making prosthesis for the proximal and distal ends of radius. (Biomed J 2015;38:323-328)

Morphometry of distal end radius in the Indian population: A radiological study

“…and Altissimi et al 25. The mean value of radial inclination of our study lies between the mean values of two Indian cadaveric studies by Gupta et al 6. and Prithishkumar et al 7.…”

“…There are very fewer studies available for the morphometry of distal radius in the Indian population 67. Hence, the unblemished intellect about the morphometry is urged for the management of DER.…”

Morphometic Examination of Radius

“…For this reason, many morphometric studies have been done about radius. Guptaet al, Gasse et al and Giannicola et al [10][11][12] found the length of radius as 23.5 cm, 22.9 cm and 22.1 cm, respectively. Prithishkumar et al [13] found the length of left and right radius as 24.4 cm and 24.2 cm, respectively.…”

Morphometry of Distal End Radius- Surgical Implication in Colles' Fracture

“…Articular reduction is best evaluated by radiocarpal arthrotomy between second and fourth dorsal compartments, just distal to lister's tubercle. (8) So distance between tip of styloid process and dorsal tubercle is an important parameter. Nutrient foramen is defined as the largest of the foramina present on the shaft of the long bones and admits a nutrient artery for that bone.…”
