Online published on 28 October, 2020. Abstract Background The shoulder prosthesis design resulted in significant reductions in loss of work force and mortality if industries manufacturing prostheses design and manufacture prostheses according to the morphometric data of the population of their own country. Objectives This morphometric evaluation was proposed to find a correspondence of the anthropometric parameters measured at the proximal and distal humeral parts of humerus. Materials and Methods The claims of this study were appraised on radiographs of dry bones. In this study, (20) dry bones available in the anatomy museum of the department of human anatomy/College of medicine/ Al-Nahrain University were used. The parameters measured on the X-ray of dry bones at the proximal and the distal parts of humerus were statistically compared and evaluated. Results Significant and high significant correlations found for the parameters provide regression equations for them; these equations allow extraction of missing limit from an available one. Accordingly, statistical regression equations has been concluded for the parameters of the proximal part of the x-ray of dry bone from the values obtained from comparable parameter of the distal part of the x-ray of dry bone. Conclusions The statistical evaluation upraised the theory of "recapitulation" and introducing a scheme for mathematic reprocessing of approximate estimation for the proper choice of humeral head arthroplasty depending on plain X-imaging to the proximal and distal part of the humerus.
