Brachial plexopathy is an injury of the brachial plexus, most commonly caused by trauma. Brachial plexus is a peripheral nervous system structure that extends from the cervicothoracic spinal cord to the axilla and provides motor, sensory, and autonomic innervation to the upper extremities. From proximal to distal, its elements are the following:. Based on whether the injury is proximal or distal to the dorsal root ganglion DRG , they are further characterized as preganglionic and postganglionic, respectively. Clinically, preganglionic injuries eg, root avulsions can be associated with Horner syndrome disruption of the autonomic trunk , medial scapular winging injury to long thoracic and dorsal scapular nerve , and denervation of the cervical paraspinal muscles. Postganglionic injuries typically carry a better prognosis because they often demonstrate greater spontaneous recovery and are more amenable to surgical repair.

Synthesized Recommendation Grading System for DynaMed Content The DynaMed Team systematically monitors clinical evidence to continuously provide a synthesis of the most valid relevant evidence to support clinical decision-making see 7-Step Evidence-Based Methodology.
Guideline recommendations summarized in the body of a DynaMed topic are provided with the recommendation grading system used in the original guideline s , and allow users to quickly see where guidelines agree and where guidelines differ from each other and from the current evidence. Strong recommendations are used when, based on the available evidence, clinicians without conflicts of interest consistently have a high degree of confidence that the desirable consequences health benefits, decreased costs and burdens outweigh the undesirable consequences harms, costs, burdens.
Weak recommendations are used when, based on the available evidence, clinicians believe that desirable and undesirable consequences are finely balanced, or appreciable uncertainty exists about the magnitude of expected consequences benefits and harms.
Weak recommendations are used when clinicians disagree in judgments of relative benefit and harm, or have limited confidence in their judgments.
Weak recommendations are also used when the range of patient values and preferences suggests that informed patients are likely to make different choices.
Recommendations are phrased to match the strength of recommendation. Strong recommendations use "should do" phrasing, or phrasing implying an expectation to perform the recommended action for most patients. Weak recommendations use "consider" or "suggested" phrasing. Recommendations are explicitly labeled as Strong recommendations or Weak recommendations when a qualified group has explicitly deliberated on making such a recommendation.
Group deliberation may occur during guideline development. When group deliberation occurs through DynaMed Team-initiated groups: Clinical questions will be formulated using the PICO Population, Intervention, Comparison, Outcome framework for all outcomes of interest specific to the recommendation to be developed. Systematic searches will be conducted for any clinical questions where systematic searches were not already completed through DynaMed content development.
Evidence will be summarized for recommendation panel review including for each outcome, the relative importance of the outcome, the estimated effects comparing intervention and comparison, the sample size, and the overall quality rating for the body of evidence.
Recommendation panel members will be selected to include at least 3 members that together have sufficient clinical expertise for the subject s pertinent to the recommendation, methodological expertise for the evidence being considered, and experience with guideline development. All recommendation panel members must disclose any potential conflicts of interest professional, intellectual, and financial , and will not be included for the specific panel if a significant conflict exists for the recommendation in question.
Panel members will make Strong recommendations if and only if there is consistent agreement in a high confidence in the likelihood that desirable consequences outweigh undesirable consequences across the majority of expected patient values and preferences. Panel members will make Weak recommendations if there is limited confidence or inconsistent assessment or dissenting opinions that desirable consequences outweigh undesirable consequences across the majority of expected patient values and preferences.
No recommendation will be made if there is insufficient confidence to make a recommendation. All steps in this process including evidence summaries which were shared with the panel, and identification of panel members will be transparent and accessible in support of the recommendation.
Recommendations are published only after consensus is established with agreement in phrasing and strength of recommendation by all editors. If consensus cannot be reached then the recommendation can be published with a notation of "dissenting commentary" and the dissenting commentary is included in the topic details.
If recommendations are questioned during peer review or post publication by a qualified individual, or reevaluation is warranted based on new information detected through systematic literature surveillance, the recommendation is subject to additional internal review.

Special acknowledgements DynaMed topics are written and edited through the collaborative efforts of the above individuals. Deputy Editors, Section Editors, and Topic Editors are active in clinical or academic medical practice. Editorial Team role definitions Topic Editors define the scope and focus of each topic by formulating a set of clinical questions and suggesting important guidelines, clinical trials, and other data to be addressed within each topic.
Topic Editors also serve as consultants for the internal DynaMed Editorial Team during the writing and editing process, and review the final topic drafts prior to publication. Section Editors have similar responsibilities to Topic Editors but have a broader role that includes the review of multiple topics, oversight of Topic Editors, and systematic surveillance of the medical literature.
Recommendations Editors provide explicit review of Overview and Recommendations sections to ensure that all recommendations are sound, supported, and evidence-based. This process is described in "Synthesized Recommendation Grading. Each is responsible for all content published within that group, including supervising topic development at all stages of the writing and editing process, final review of all topics prior to publication, and direction of an internal team.

Ferrante Published ABSTRACT: The brachial plexus, which is the most complex structure of the peripheral nervous system, supplies most of the upper extremity and shoulder. The high incidence of brachial plexopathies reflects its vulnerability to trauma and the tendency of disorders involving adjacent structures to affect it secondarily.
