While both elbow flexion and forearm supination strength are affected, there is a greater percentage loss of supination strength. Patients may complain of weakness and fatigue with rotational activities such as using a screwdriver. The primary elbow flexor is actually the brachialis, and therefore less weakness in flexion is reported. Patterson reviewed distal biceps ruptures and found nonsurgical treatments had 21–55% loss of supination strength and 8–36% loss of flexion strength. Klonz reviewed anatomic and non-anatomic repairs and found better results with anatomic repairs with 91% return of supination strength and 96% return of flexion strength. Supination strength after nonanatomic repair did not improve in 4 of 8 patients (42%-56% of the uninjured arm).
