Musculus extensor digiti minimi is situated medially from the extensor digitorum and joins its tendon. Insertion: Origin is on the lateral epicondyle of the humerus. Distal insertion is an extensor expansion of little finger with extensor digitorum tendon. Action: It is the extensor of little finger and contributes to the extension of the hand. Innervation is assured by radial nerve (C6, C7).

Traumatic epiphyseal arrest refers to premature closure of a bony growth plate due to failure of recognition or inadequate management of a growth plate fracture in a child. An example of this is fracture of the lateral epicondyle of the humerus leading to premature closure of the growth plate and alteration of the carrying angle of the elbow.

Always look for the “triangle” in the elbow, made of the lateral epicondyle of the humerus, the radial head, and the olecranon.

Next, anthropometric measurements were obtained to estimate the inertial properties of the arm (De Leva, 1996), necessary for estimating torque around the shoulder. The SJC of the right arm was defined and marked on the subject as the point through which the axes of rotation intersected in both planes (sagittal and horizontal). When the arms were elevated, a vertical translation of the SJC marker occurred due to skin and muscle movement. Therefore, a second SJC was defined with the arm in 90° flexion, to match recorded SJC height. The elbow joint was marked at the lateral epicondyle of the humerus. Markers at the shoulder and elbow were used as reference points that lined up with markers on the window.

Participants with lateral epicondylitis at the age range of 20–60 recognized by a physical medicine specialist. At least three weeks had elapsed since the onset of their symptoms (Sadeghi-Demneh & Jafarian, 2013). The final diagnosis was made based on two criteria: 1. Pain and tenderness in the lateral epicondyle of the humerus; 2. Pain exacerbating by resistance extension of the wrist or middle finger. Participants with a history of fractures, surgery, neuropathy, steroid injections, and any painkiller consumption (in the last week) were excluded from the study.
