Morphometric scrutiny of the radial head: A foundation for prosthesis crafting

Abstract

Background: Radius is one of the two constituent bones of the forearm. It is frequently fractured or dislocated due to trauma, pathology, etc. Prosthetic radial head may be indicated in the management of comminuted fractures of the radial head. Aims and Objectives: This study was undertaken with the aim to measure various dimensions of the head of the radius bone and to collate these dimensions between right-sided and left-sided bones. Materials and Methods: Three hundred bones, collected from the Department of Anatomy of Jawaharlal Nehru Medical College, Belagavi, Karnataka, were systematically investigated using digital Vernier caliper, normal ruler, and inelastic thread. The data recorded were then analyzed to obtain the results. Results: The mean length, diameter, and circumference of the head of the radius bones were 9.47 ± 1.49 mm, 19.92 ± 2.03 mm, and 6.42 ± 0.63 cm, respectively (irrespective of the side). For only one aspect, the length of the radial head, a statistically significant difference was obtained between the values of bones of both sides. Conclusion: Numerous studies have shown an extensively varied range of values for several parameters. Utmost care and precision are required by the orthopedic surgeons, prosthetists, etc. while treating patients or prosthesis making, to avoid untoward outcomes like soreness, etc. This study strives to underline this need for precision by highlighting the varied range of parameters in the regional population.
