BACKGROUND: Primary exploration of the brachial plexus in infants with obstetric palsy may reveal scarring of the lower roots with evidence of partial avulsion-in-situ. As we have been treating this lesion by neurolysis only, we aimed to investigate the recovery of hand function following such approach. METHODS: A series of 14 cases of total obstetric palsy with with evidence of partial avulsion-in-situ of the lower roots were included. All lesions were treated by neurolysis only (with no neurotization of the lower roots)...

We suggest short range stiffness (SRS) at the elbow joint as an alternative diagnostic for EMG to assess cocontraction. Elbow SRS is compared between obstetric brachial plexus lesion (OBPL) patients and healthy subjects (cross-sectional study design). Seven controls (median 28years) and five patients (median 31years) isometrically flexed and extended the elbow at rest and three additional torques [2.1,4.3,6.4Nm] while a fast stretch stimulus was applied. SRS was estimated in silico using a neuromechanical elbow model simulating the torque response from the imposed elbow angle...

Most of the cases of obstetric brachial plexus lesions (OBPL) show satisfactory improvement with conservative management, but in about 25% some surgical treatment is indicated. The present paper analyzes the effects of primary reconstructive surgeries in aspect of achieving delineated intraoperatively goals. Children operated before the age of 18 months with follow-up period longer than 1 year were selected. Therapeutic goals established during the operation were identified by analysis of initial clinical status and operative protocols...

INTRODUCTION: Obstetric brachial plexus palsy is related with shoulder dystocia, and its main risk factor is macrosomia. Its incidence is estimated to be between 0.1 and 6.3 cases per 1,000 live newborn infants. Most cases are resolved but can give rise to permanent functional deficiency, which means that there is an interest to identify possible prognostic factors. PATIENTS AND METHODS: We conducted a descriptive study of newborn infants with obstetric brachial plexus palsy born in our hospital between the years 2011 and 2015...

BACKGROUND: Obstetric brachial plexus lesion (OBPL) frequently leads to glenohumeral dysplasia, and excessive retroversion of the glenoid is among the best known developmental disturbances. Most analyses of the glenoid are based on 2-dimensional (D) imaging and do not address glenoid inclination or provide information on the glenoid in the sagittal plane. We aim to describe the 3-D deformity of the glenoid in children with OBPL. METHODS: Preoperative computed tomography (CT) scans of the nonaffected and the affected scapula of 24 children (aged 5 to 12 years) with developmental disturbances after OBPL years were analyzed...

Clinically in obstetric brachial plexus palsy (OBPP), irreversible atrophy of intrinsic musculature of the hand in denervation occurs much earlier than that of denervated arm muscles. With the aim of finding clues to explain this, the miRNA expression profile of denervated intrinsic musculature of the forepaw (IMF) and that of the denervated biceps were examined by microarray screening in the rat model simulating irreversible muscular atrophy caused by pan-plexus lesions of OBPP, and potential targets of specifically dysregulated miRNAs were predicted with use of bioinformatics analysis...

BACKGROUND: Scapular position and size deficiency is evident in obstetric brachial plexus paralysis (OBPP) patients due to the absence of balanced muscular forces acting on the scapula. Scapula stabilization (SS) procedures aim to restore a balanced musculature and anatomic position and to augment shoulder function and enhance developmental potential. METHODS: Retrospective chart review of 106 patients with OBPP between March 1979 and March 2007 was performed. Forty-one female and 27 male were included in the study...

BACKGROUND: C5-C6 root avulsion in obstetrical brachial plexus palsy (OBPP) is a rare injury with poor prognosis usually associated with breech delivery. The treatment is challenging and requires high microsurgical skills. The triple nerve transfer (spinal accessory nerve, ulnar fascicles, and triceps long or lateral head branch) represents the gold standard treatment. The total ipsilateral C7 nerve root neurotization is a promising technique, which has never been described in OBPP. OBJECTIVE: The total ipsilateral C7 nerve root is used as a neurotizer transferred to the upper trunk as an alternative method to other intra- or extra-plexual reconstruction techniques...

COMPARATIVE STUDY
W Pondaag, M J A Malessy
In obstetric brachial plexus lesions with avulsion injury, nerve grafting for biceps muscle re-innervation may not be possible owing to the unavailability of a proximal stump. In such cases, the intercostal nerves or medial pectoral nerve can serve as donor nerves in an end-to-end transfer to the musculocutaneous nerve. The present study reports the results of both techniques from a single institution in a consecutive series of 42 patients between 1995 and 2008. From 1995 to 2000 we always used the intercostal nerve transfer, and from 2001 to 2008 both techniques were used...

We investigated the predictive value of intra-operative neurophysiological investigations in obstetric brachial plexus injuries. Between January 2005 and June 2011 a total of 32 infants of 206 referred to our unit underwent exploration of the plexus, including neurolysis. The findings from intra-operative electromyography, sensory evoked potentials across the lesion and gross muscular response to stimulation were evaluated. A total of 22 infants underwent neurolysis alone and ten had microsurgical reconstruction...
