“…None of the previous studies have measured depth of radial head on dry bone. They mainly measured depth with the of computer tomography [4,9,10]. Depth of radial head in the present study (1.74 mm) was within range of previous studies (1.5-2.4mm).…”

“…[10] Swieszkowski et al found the mean depth of articular facet as 0.19 cm, and we also got similar value in our study (0.19 cm). [11] Mazzocca et al found the mean length and width of bicipital tuberosity as 2.2 and 1.5 cm, respectively. They also found that the bicipital tuberosity ridge was smooth in 6% of specimens, bifid in 6%, and the remaining 88% of specimens had a single ridge.…”

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)

“…The anatomical landmarks of the safe zone have been investigated in a few studies [16][17][18]. Further studies analyzed the morphometric aspects of the proximal radius including the diameters of radial head and neck, neck length, radial head height, articular surface depth, radial head-neck angles, and neck-shaft angle [19][20][21][22][23][24][25][26][27]. These investigations were aimed at analyzing the morphometric aspects of the proximal radius to design well-performing radial head prostheses, while none of them were focused on the morphology of the safe zone in order to improve the accuracy of radial head osteosynthesis.…”

In the last few years, several anatomical plates have been introduced to improve the results of ORIF in Mason Type II and III radial head fractures. However, no study analyzed whether currently used plates match adequately the profile of the proximal radius in the "safe zone". In the present investigation, we evaluate the congruence between the proximal radius and a currently used plate. Forty-four radial dried cadaveric bones were analyzed. The plate congruence was evaluated qualitatively and quantitatively. The congruence of the tested plate with the proximal radius was good in 27.3% of specimens, while it was moderate or poor in the remaining 43.2% and 29.5% of cases, respectively. The profile of the proximal radius in the "safe zone" shows substantial morphologic variations which should be taken into account to avoid a malunion of the proximal radius. A preoperative radiograph of the contralateral uninjured radius may be helpful in order to select the most appropriate plate profile in comminuted radial head and neck fractures.
