[The relative value of electromyography (EMG) in the evaluation of the results of surgical repair of biceps tendon rupture in the arm].
Ten patients treated for rupture of a biceps tendon were re-evaluated 2 years or longer after surgery. Four patients complained of loss of strength and increased fatigue. The concentric EMG examination and the technically more demanding Macro EMG technique showed normal motor unit action potential patterns in the muscle operated on and in the contralateral muscle used as control. The symptom weakness could not be explained by myopathic or neurogenic muscle changes. Concentric EMG had the same diagnostic yield as Macro EMG in this study. Concentric EMG is sufficient to scan for pathological findings within the biceps muscle. If any are present they should initially be interpreted as evidence of a further pathologic condition and not as sequelae of the tendon rupture.
