Hypoglossal nerve transfer in obstetric brachial plexus palsy.

A cost-benefit analysis was performed of hypoglossal nerve transfer in six patients with obstetric brachial palsy taking into account the factors donor site morbidity and extent of recovery. Hypoglossal nerve transfer was employed in four children for elbow flexion only; in two patients for elbow flexion as well as for elbow extension. The transfer was part of an extended brachial plexus reconstruction for treatment of obstetric brachial plexus palsy.

Transfer of pectoral nerves to the musculocutaneous nerve in obstetric upper brachial plexus palsy.

Objective: To investigate the results of transfer of pectoral nerves to the musculocutaneous nerve for treatment of obstetric brachial palsy.

Methods: In 25 cases of obstetric brachial palsy (20 after breech deliveries), branches of the pectoral nerve plexus were transferred directly to the musculocutaneous nerve. For all patients, the nerve transfer was part of an extended brachial plexus reconstruction.

Extensive somatosensory innervation in infants with obstetric brachial palsy.

In the pre-operative screening of infants with obstetric brachial palsy (OBP), the results of routine electromyography are often overly optimistic when compared to the peri-operative findings. This prompted us to include investigation of the sensory innervation of these infants using the N20 (the first cortical response to a peripheral stimulation) of the somatosensory evoked potentials (SSEP). Three to seven months after birth, SSEP were recorded at the skull after stimulation of the thumb and middle finger in infants with obstetric rupture of the upper trunk or avulsion of roots C5, C6, or C7, and in whom no clinical improvement of motor function was observed in the biceps brachii and deltoid muscles.

Bacterial contamination of femoral head allografts from living donors.

We analyzed the bacterial contamination rate of femoral head allografts from living donors and determined the true bacterial load with cultures from the grafts in their entirety in a specially prepared medium. During 4 years we took swab cultures from 2,679 grafts of which 2,414 (90%) were negative. In a period of 12 months, grafts rejected for reasons other than infectious disease were cultured in their entirety to determine the true bacterial load.

Management of obstetric brachial plexus lesions: state of the art and future developments.

Despite improving perinatal care the incidence of obstetric brachial plexus lesions (OBPL) has not declined. Most babies recover spontaneously. In 10-20% recovery is incomplete.
