Abstract
Background:In the restoration of elbow flexion, the phrenic nerve has proven to be a good donor, but considering the role of the phrenic nerve in respiratory function, we cannot disregard the potential dangers of this method.Objectives:In the current study, we reviewed the results of pulmonary function tests (PFT) in four patients who underwent phrenic nerve transfer.Patients and Methods:We reviewed the results of serial spirometry tests, which were performed before and after phrenic nerve transfer surgery.Results:All patients regained Biceps power to M3 strength or above. None of our patients experienced pulmonary problems or respiratory complaints, but a significant reduction of spirometric parameters occurred after surgery.Conclusions:This study highlights the close link between the role of the phrenic nerve and pulmonary function, such that the use of this nerve as a transfer donor leads to spirometric impairments.
