Spinal Nerves: Plexus I

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Diabetic Neuropathy

Diabetic Neuropathy

DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...

Summary

Wheelchair users can develop radial neuropathy from arm compression against hard surfaces. Proper arm positioning is crucial to prevent this nerve injury.

Area of Science:

Neurology
Orthopedics
Rehabilitation Medicine

Background:

Radial neuropathy is a common nerve disorder.
Wheelchair use can lead to various physical complications.
Understanding specific injury mechanisms is vital for prevention.

Observation:

Two cases of radial neuropathy were identified in wheelchair users.
The compression occurred at the spiral groove of the humerus.
Contact with hard wheelchair surfaces (armrest, back support) was implicated.

Findings:

Compression neuropathy of the radial nerve resulted from prolonged contact with rigid wheelchair components.
The spiral groove of the humerus is particularly vulnerable to external pressure in this context.

Implications:

Wheelchair users and caregivers should be educated on proper arm placement.
Wheelchair design may need to consider pressure-relief features for the upper arms.
Further research into preventative strategies for wheelchair-related nerve injuries is warranted.
