Kinds of Plexus Injury Selected AbstractsNeurological recovery in obstetric brachial plexus injuries: an historical cohort studyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 2 2004Agnes F Hoeksma MD An historical cohort study was conducted to investigate the rate and extent of neurological recovery in obstetric brachial plexus injury (OBPI) and to identify possible prognostic factors in a cohort of children with OBPI from birth to 7 years. All children (n=56; 31 females, 25 males) with OBPI were evaluated at fixed time intervals by one examiner. They underwent a final neurological examination at a mean age of 3 years 10 months (range 1 to 7 years). Neurological outcome was not as favourable as is often reported: complete neurological recovery occurred in 37 out of 56 children (66%). In half of these there was delayed recovery, in which case complete neurological recovery was assessed from 1.5 to 16 months of age (median age 6.5 months, SD 4.2 months). External rotation and supination were the last to recover and recovered the least. Although biceps function at three months was considered to be the best indicator for operative treatment, external rotation and supination were found to be better in predicting eventual complete recovery. Initial symptoms directly post partum were not found to be prognostic. Functional outcome was mainly reported to be good.

Nicolaidis M.D. The value of continuous electrical stimulation of denervated muscles after nerve injury and repair has been clearly shown in a series of laboratory experiments in three animal models. This experimental background, which showed improved muscle preservation and better functional results, evolved into a clinical study that included 15 patients with peripheral nerve injuries in the upper extremities, 3 patients with brachial plexus injuries, and three patients with facial nerve paralysis. Improved functional results were obtained using this implantable system, which were similar to those achieved with the animal experiments. All patients had muscle stimulation for extended periods ranging from 127 to 346 days. Analysis of the results showed satisfactory nerve regeneration on clinical examination and with electromyographic studies. Functional muscle analysis varied somewhat from patient to patient, but every patient had a satisfactory to excellent recovery. The results from this study have clearly shown the benefits of continuous muscle stimulation using an implantable electrical system after nerve injury and repair expansion of the project to a larger patient cohort is indicated. © 2001 Wiley-Liss, Inc.

[source] Histopathological basis of Horner's syndrome in obstetric brachial plexus palsy differs from that in adult brachial plexus injuryMUSCLE AND NERVE, Issue 5 2008Yi-Gang Huang MD Abstract Although Horner's syndrome is usually taken as an absolute indicator of avulsions of the C8 and T1 ventral roots in adult brachial plexus injury, its pathological basis in obstetric brachial plexus palsy (OBPP) is unclear. We therefore examined the morphological mechanism for the presence of Horner's syndrome in brachial plexus injury in infants and adults. Some axons of sympathetic preganglionic neurons in T1 innervate the superior cervical ganglion via the C7 ventral root in infants but not in adults. Therefore, the presence of Horner's syndrome may relate in part to avulsion of the C7 root in OBPP. These findings suggest that Horner's syndrome in OBPP is not necessarily indicative of avulsions of the C8 and T1 roots, as it can occur with avulsion of the C7 root.

(Kocaeli University, Kocaeli, Turkey) Arch Phys Med Rehabil 1999; 81:944,946. This is a case-controlled study of the relationship between glenohumeral joint subluxation and reflex sympathetic dystrophy (RSD) in hemiplegic patients set in an inpatient rehabilitation hospital. Thirty-five hemiplegic patients with RSD (RSD group) and 35 hemiplegic patients without RSD (non-RSD group) were included in this study. Patients with rotator cuff rupture, brachial plexus injury, or spasticity greater than stage 2 on the Ashworth scale were excluded. Both the RSD and non-RSD groups were assessed for presence and grade of subluxation from radiographs using a 5-point categorization. The degree of shoulder pain of the non-RSD group was assessed by a visual analogue scale of 10 points. Glenohumeral subluxation was found in 74.3% of the RSD group and 40% of the non-RSD group (P = 0.004). In the non-RSD group, 78.6% of the patients with subluxation and 38.1% of the patients without subluxation reported shoulder pain (P = 0.019). No correlation was found between the degree of shoulder pain and grade of subluxation in the non-RSD group (P = 0.152). Conclude that the findings suggest that shoulder subluxation may be a causative factor for RSD. Therefore, prevention and appropriate treatment of glenohumeral joint subluxation should be included in rehabilitation of hemiplegic patients. Comment by Miles Day, MD. The purpose of this study was to examine the relationship between shoulder subluxation in hemiplegic patients and reflex sympathetic dystrophy. They also examined if subluxation is associated with shoulder pain and the grade of subluxation in patients with subluxation and no reflex sympathetic dystrophy (RSD). Patients with injuries to the rotator cuff of the brachial plexus, marked spasticity, and major trauma to joint structures were excluded as these can be precipitating factors for RSD. The study noted a significantly higher presence of shoulder subluxation within the RSD group and the presence of pain was significantly high in patients with shoulder subluxation in the non-RSD group. The take home message of this article is that any measure or treatment that can be applied to the glenohumeral joint should be performed to eliminate the possibility of the patient developing RSD and subsequently hindering further rehabilitation in these patients.

Objectives,,, Examination of the relationship between pain, sensory hypersensitivity, referred sensations and involuntary muscle jerks in patients with brachial plexus injury. Materials and methods,,, Fourteen patients with brachial plexus lesions were included. Spontaneous background and paroxysmal pain and mechanically and thermally evoked pain were recorded. Areas with sensory hypersensitivity and referred pain were mapped on a body chart. This was supplemented by electrophysiological analysis in three patients. Results,,, Sensory hypersensitivity and areas with pinprick-induced referred phantom sensations were present in adjacent dermatomes. There was no clear relationship between chronic neuropathic pain and referred sensations, but there was a correlation between pain paroxysms and sensory hypersensitivity in dermatomes adjacent to deafferented areas. In three patients, simultaneous referred sensations and short latency motor action potentials ipsilateral to the denervated side suggested origin at subcortical sites. Conclusion,,, The study suggests a possible role of a spinal generator for sensory hypersensitivity and referred sensations following denervation. [source] Anatomical study to investigate the feasibility of pedicled nerve, free vessel gastrocnemius muscle transfer for restoration of biceps functionCLINICAL ANATOMY, Issue 4 2001Lucy Katharine Cogswell Abstract A challenging problem is the patient with a total brachial plexus injury with nerve root avulsions. In these patients nerve repair is not possible and no local functioning muscles are available for transfer. Current techniques involve either nerve repair using donor nerves from the contralateral limb or free muscle transfer neurotized by intercostal nerves. The problem with both these techniques is that they are dependent on neural regeneration, which is imperfect. To overcome the problem we propose a technique of transferring a distant muscle whilst retaining its neural supply. Gastrocnemius is a strong muscle and one suitable for free tissue transfer. This study assessed the possibility of transferring gastrocnemius on its neural supply by determining the length of nerve available and whether it was possible to dissect the nerve to gastrocnemius from the main body of the sciatic nerve. We found that the latter was possible, and that the length of dissected nerve would allow transfer of the innervated muscle from the calf to the axilla. Clin.
