Summary
Median nerve neuropathy is common after perilunate dislocations, often persisting despite surgery. Early carpal tunnel release does not always prevent long-term nerve issues and poorer outcomes.
Area of Science:
- Orthopedic Surgery
- Neurology
- Traumatology
Background:
- Perilunate dislocations are severe wrist injuries.
- Median nerve involvement can complicate recovery.
- Surgical decompression is a common treatment.
Purpose of the Study:
- To determine the frequency and presentation of median nerve neuropathy after perilunate dislocations.
- To assess the impact of surgical decompression on neuropathy.
- To correlate neuropathy with clinical outcomes.
Main Methods:
- Retrospective study of 32 patients with perilunate dislocations.
- Follow-up averaged 65 months post-surgery.
- Electrophysiological testing and clinical outcome measures (DASH, pain, grip strength, Mayo score) were used.
Main Results:
- Median nerve neuropathy occurred in a significant number of patients.
- Neuropathy persisted in 6 patients despite carpal tunnel release.
- Patients with neuropathy experienced worse pain, grip strength, and functional scores.
Conclusions:
- Median nerve neuropathy is a frequent complication of perilunate dislocations.
- It often presents as a chronic lesion rather than acute compression.
- Carpal tunnel release may not prevent persistent neurological deficits.

3.3K
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.

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...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
760
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...

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.7K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
