Land marks and safety with respect to radial nerve in distal humeral surgery

Abstract

The study analyzed 20 elbows from 10 preserved male human cadavers (10 right and 10 left), which were selected based on strict inclusion criteria. Cadavers with a history of prior surgery, infection, trauma or deformity were excluded from the sample. The average age of the cadavers was 46 years, ranging from 28 to 64 years. The precise measurements were obtained using the Microscribe-G2X device, renowned for its accuracy of up to one-thousandth of a millimeter. The length from the pivot point of the radial nerve in the sulcus nervi radialis to the distal end of the humerus is measured, along with the transverse diameter between the lateral epicondyle and the radial nerve and the length of the humerus itself. The length from the pivot point of the radial nerve in the sulcus nervi radialis to the distal end of the humerus is measured, along with the transverse diameter between the lateral epicondyle and the radial nerve and the length of the humerus itself. The length from the pivot point of the radial nerve in the sulcus nervi radialis to the distal end of the humerus is measured, along with the transverse diameter between the lateral epicondyle and the radial nerve and the length of the humerus itself. The right and left sides were measured to be 30.54±0.65cm and 30.54±0.59cm, respectively, with no considerable difference between them. The distance from the pivot point of the radial nerve in the sulcus nervi radialis to the distal part of the humerus was 15.07±1.27cm on the right side and 15.34±1.21cm on the left side. On the right, the distance was 15.07±1.27cm, while on the left, it was 15.34±1.21cm. Moreover, the transverse diameter between the lateral epicondyle and the radial nerve was measured at 2.95±0.14cm on the right side and 3.05±0.13cm on the left side. We contend that comprehension of the safe zone in distal humerus surgery can greatly improve surgical safety.
