Mononeuropathies are unusual at birth, and electromyographic (EMG) definition the first day of life has not been reported previously. Although neonatal mononeuropathies may be related to obstetric complications, prenatal mechanisms also merit consideration. We report an infant, born with a peroneal neuropathy, whose EMG was performed 18 h after birth. An isolated peroneal nerve lesion with lack of compound muscle action potential and the presence of fibrillation potentials, confined to the tibialis anterior muscle, suggested a primary intrauterine mechanism for this mononeuropathy. Because of an infant's small size, the temporal profile used in adults for appearance of EMG signs of wallerian degeneration may not apply. Inaccurate conclusions may result if the EMG standards for timing adult nerve injury are applied to newborns. To our knowledge, previous published cases of neonatal mononeuropathies have not included babies whose first EMG was performed before age 4 days. Therefore, an EMG study shortly after birth needed to be accomplished if strong support for the hypothesis of a prenatal onset were to be generated. Our findings are compatible with an intrauterine onset of this baby's peroneal neuropathy.
Traumatic tetraplegia is an overwhelming injury often requiring permanent adaptations by patients and families. The greatest potential for improving the quality of life lies with rehabilitation and restoration of upper extremity function. Reconstructive hand surgery following tetraplegia is individualized based on functional level and can significantly improve hand function and quality of life. Careful selection and evaluation of surgical candidates in combination with an experienced surgeon and hand rehabilitation team are critical for a successful outcome.
The history of clinical application of electromyographic and electroneurographic techniques is not even 60 years old. For a long time the clinicians' need could not be fulfilled, due to the imperfection of the electronic equipment. Nowadays, electromyography and electroneurography are established methods not only for the diagnosis of neuromuscular disorders, but since the recording of cortical and spinal evoked potentials has been introduced, diseases of the central nervous system lie also within its scope.
