We report 2 patients with obstetrical brachial plexus palsy, ipsilateral leg weakness, and contralateral motor cortical dysplasia. To our knowledge, this is the first description of such an association. In both cases, the diagnosis of obstetrical brachial plexus palsy was established clinically shortly after birth and later confirmed neurophysiologically. Motor cortex dysplasia was diagnosed by magnetic resonance imaging (MRI). The association of obstetrical brachial plexus palsy and contralateral motor cortex dysplasia, a condition known to produce congenital hemiparesis, raises the possibility that the cortical dysplasia was a predisposing factor for obstetrical brachial plexus palsy in these cases.

Obstetric brachial plexus injury (OBPI) is an important preventable complication of the birth process. While most cases recover in the early period, a substantial number result in sequelae. Despite established risk factors, there are cases that occur without any apparent risk factors.

Purpose: This study evaluated the efficacy of the spinal accessory to suprascapular nerve transfer accompanied by anterior shoulder release in restoring shoulder external rotation and abduction in patients with brachial plexus birth injury.

Methods: A cohort of 41 children with brachial plexus birth injury and shoulder internal rotation contractures underwent surgical intervention. The procedure involved an anterior shoulder release encompassing subscapularis tenotomy, capsulotomy and division of the coracohumeral ligament, and transfer of the spinal accessory nerve to the suprascapular nerve.

Article Synopsis
  • The study assessed the impact of exercise training during pregnancy on factors like peak oxygen uptake (V̇Opeak), cardiac function, and flow-mediated dilatation (FMD) in individuals with a prepregnancy BMI of 28 kg/m or higher.
  • The exercise intervention consisted of three weekly sessions of moderate-intensity walking and strength exercises, starting between 12 and 18 weeks of pregnancy and continuing until delivery.
  • Results showed no significant improvements in V̇Opeak, FMD, or echocardiographic outcomes between the exercise and control groups, with only 50% adherence to the exercise program among participants.

The objective of this study is to examine the correlation between the active range of motion (ROM) of the affected upper extremity and functional capacity in children with Obstetric Brachial Plexus Palsy (OBPP) who have undergone the modified Hoffer tendon transfer technique. The study cohort comprised 52 children with OBPP, aged 4-14 years, who had undergone a shoulder tendon transfer. The ROM was quantified using a goniometer, while functionality was evaluated through the administration of the Brachial Plexus Outcome Measure (BPOM).
