Neonatal brachial plexus palsy is a devastating complication after a difficult delivery. The incidence of this injury has not significantly decreased over the past decades, despite all the advances in perinatal care. Although primary repair of the nerves with microsurgical techniques is the common treatment strategy nowadays, there are late cases in which secondary procedures in tendons or bones are necessary.

Purpose: The outcome from microsurgical reconstruction of neonatal brachial plexus palsy (NBPP) varies, and comparison between different series is difficult, given the differences in preoperative evaluation, surgical strategies, and outcome analysis. To evaluate our results, we reviewed a series of children who underwent surgical treatment in a period of 14 years.

Methods: We made a retrospective review of 104 cases in which microsurgical repair of the brachial plexus was performed. Read More

Brachial plexus birth injury (BPBI) and phrenic nerve injury can sometimes occur concurrently in neonates following difficult deliveries like breech presentation, shoulder dystocia, forceps or vacuum extraction. Phrenic nerve palsy should be suspected in a newborn with respiratory distress and an elevated hemidiaphragm on the imaging studies in presence of the associated risk factors. The right side is affected more often than the left side and most of it is associated with BPBI. Read More

Background: Latissimus dorsi (LD) and teres major (TM) tendon transfers are effective surgical procedures to improve shoulder abduction and external rotation for children with obstetrical brachial plexus palsy (OBPP). Open pectoralis major (PM) tendon Z-plasty and arthroscopic subscapularis (SS) release are 2 options for the release of internal rotation contractures to enhance muscle transfers. This study compared the functional results of LD and TM tendon transfers with open PM tendon Z-plasty or arthroscopic SS release. Read More

Shoulder dystocia is a rare but severe obstetric complication associated with an increased risk of brachial plexus palsies, fractures of the clavicle and humerus, hypoxic-ischemic encephalopathy and, rarely, neonatal death. Here we describe a fatal case of shoulder dystocia in a term newborn, although labor was uneventful, fetal heart rate tracing was normal until the delivery of the head and the head-to-body delivery interval (HBDI) occurred within 5 min. Full resuscitation was performed for 35 min without success. Read More

Background: Most brachial plexus birth injuries (BPBI) are caused by traction on the brachial plexus during a difficult delivery. Fortunately, the possibility of complete recovery from such an incident is relatively high, with only 10% to 30% of patients having prolonged and persistent disability. These patients have muscle imbalances and co-contractions typically localized around the shoulder and elbow. Read More

Purpose: Ulnar and median nerve transfers to arm muscles have been used to recover elbow flexion in infants with neonatal brachial plexus palsy, but there is no direct outcome comparison with the classical supraclavicular nerve grafting approach.

Methods: We retrospectively analyzed patients with C5-C7 neonatal brachial plexus palsy submitted to nerve surgery and recorded elbow flexion recovery using the active movement scale (0-7) at 12 and 24 months after surgery. We compared 13 patients submitted to supraclavicular nerve grafting with 21 patients submitted to distal ulnar or median nerve transfer to biceps motor branch. Read More

In this study, we report the outcome for spontaneous recovery of elbow flexion in obstetric brachial plexus injury managed without nerve reconstruction. Excluding those with transient paralysis, our records revealed 152 children with obstetric brachial plexus injury born before our unit routinely offered brachial plexus reconstruction.

Background: Early detection of posterior shoulder dislocation in infants with brachial plexus birth palsy (BPBP) is essential, but it may be difficult to accomplish with physical examination alone. The aim of this study was to determine the prevalence of shoulder dislocation in patients with BPBP using ultrasound and to identify which physical examination measurements correlated most with dislocation in these patients.

Methods: This study was a retrospective review of data obtained in an ultrasound screening program of infants with BPBP born from January 2011 to April 2014. Read More

Background And Purpose: The current prognostic biomarker of functional outcome in brachial plexus birth palsy is serial clinical examination throughout the first 6 months of age. This can delay surgical treatment and prolong parental anxiety in neonates who will recover spontaneously. A potentially superior biomarker is a volumetric proton density MRI performed at clinical presentation and within the first 12 weeks of life, providing a high spatial and contrast resolution examination in 4 minutes.

Background: Currently, no published, validated patient-reported outcome (PRO) measures of health-related quality of life (HRQOL) exist for use with neonatal brachial plexus palsy (NBPP). NBPP is a debilitating condition that occurs during the perinatal period, resulting in paralysis/paresis and loss of sensation in the affected arm. Commonly used NBPP measures are not comprehensive and do not fully account for clinically meaningful changes in function or progression of the disorder. Read More

Background: Routine sensory assessments in neonatal brachial plexus palsy are infrequently performed because it is generally assumed that sensory recovery exceeds motor recovery. However, studies examining sensory function in neonatal brachial plexus palsy have produced equivocal findings. The purpose of this study was to examine hand sensorimotor function in older children with neonatal brachial plexus palsy using standard clinical and research-based measures of tactile sensibility.

Objective: Birth palsy, otherwise known as obstetric brachial plexus paralysis (OBPP), is a closed stretch injury to the brachial plexus of nerves during the birth process resulting in varying degree of paralysis and contractures of the upper limb. The study aimed to find out the susceptibility of humans and small-bodied primates to birth palsy.

Method: A comparative study on parturition in modern humans, hominoids, hominids, small-bodied primates and great apes was done to determine if the changes in female pelvis and neonatal head and shoulder during human evolution is the real cause for OBPP. Read More

Background: Children with neonatal brachial plexus palsy (NBPP) are often prescribed shoulder range of motion (ROM) exercises; however, the extent and timing of exercise implementation remains controversial in the context of shoulder joint integrity. The association of ROM exercises to delayed posterior shoulder subluxation (PSS) is unknown.

Aim: To systematically review and analyze the overall impact and effectiveness of bony surgical procedures, the triangle tilt and humeral surgery in a comparative manner in permanent obstetric brachial plexus injury (OBPI) patients.

Methods: We conducted a literature search and identified original full research articles of OBPI patients treated with a secondary bony surgery, particularly addressing the limitation of shoulder abduction and functions. Further, we analyzed and compared the efficacy and the surgical outcomes of 9 humeral surgery papers with 179 patients, and 4 of our secondary bony procedure, the triangle tilt surgical papers with 86 patients.

Background And Objectives: A practice advisory on regional anesthesia in children in 2008, published in this journal, supported the placement of regional blocks in children under general anesthesia (GA). Interscalene brachial plexus (IS) blocks were specifically excluded, based on case reports (level 3 evidence) of injury, which occurred predominantly in heavily sedated or anesthetized adult patients. Apart from case reports, there is a paucity of data that explore the safety of IS blocks placed in patients under GA, and the level of evidence available on which to base recommendations is limited.
