The distal radius is one of the more common fracture sites of the human long bones. No one-treatment modality is applicable to all the distal radius fractures. Due to various fixation and anatomic issues, the volar surface can be considered an appropriate site for the palmar locking plate for the treatment of unstable dislocated distal radius fractures. In case of a wrist injury involving distal radius, a distal volar radius plate used may not provide the optimum buttress effect due to its inefficiency to lie in close proximity with the distal volar surface. This project geometrically analyzed the distal volar surfaces of 9 randomly chosen radii. A family of polynomial equations representing the mid saggital deviations of the volar surface were obtained. This study will aid in the design of distal volar implants and will provide a more meaningful approach to distal fracture fixation techniques. A family of polynomial rational equations was obtained that defined the geometry of inter mid saggital volar surface of the given radii. The diaphysial region of the radius was more predictable with the residual dimensions, between the y values obtained from the equations and the volar surface, being in the clinically acceptable range of –0.5 to 1.5 mm. At the metaphysial region, in and around the centroidal plane, the equationspredicted the surface in the clinically significant range. As we approached the medial and lateral end of the metaphysis, the residual quantity surpassed the clinical significant range. The variance of the three lower order pertinent constants in the equations across the size distribution of the radii, were statistically analyzed and regressed to obtain pertinent relationships. The results obtained define the variation in the volar surface but fail to provide an applicable solution to the problem of obtaining a surface equation that will aid in manufacturing distal volar radius plates. A future study is recommended based on the protocol designed and the results obtained.
