What is interosseous muscle wasting?

What is interosseous muscle wasting?

Wasting of the interossei (prominent guttering of the back of the hand), of the web space between thumb and index finger, and softening and flattening of the hypothenar eminence with sparing of abductor pollicis brevis indicates an ulnar nerve lesion.

What causes first dorsal interosseous atrophy?

Dissociated atrophy of hand muscles is a characteristic feature of ALS. It is highly specific for ALS because a lesion in ulnar nerve or lower trunk will cause predominant wasting of first dorsal interossei and hypothenar with preserved thenar as it is innervated by median nerve.

What disease causes muscles to degenerate and atrophy?

What is muscular dystrophy? Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement.

What disease affects your muscles?

Types of neuromuscular disorders include:

  • Amyotrophic lateral sclerosis (ALS)
  • Charcot-Marie-Tooth disease.
  • Multiple sclerosis.
  • Muscular dystrophy.
  • Myasthenia gravis.
  • Myopathy.
  • Myositis, including polymyositis and dermatomyositis.
  • Peripheral neuropathy.

What are some neuromuscular diseases?

Neuromuscular Disease Overview

  • Amyotrophic lateral sclerosis (ALS)
  • Botulism.
  • Congenital myasthenic syndromes.
  • Congenital myopathies.
  • Cramp-fasciculation syndrome.
  • Elevated creatine kinase.
  • Inclusion-body myositis.
  • Lambert-Eaton syndrome.

What is thenar atrophy?

Carpal tunnel syndrome (CTS) is defined as numbness, nocturnal paresthesia, and hypoesthesia in the skin innervated by the median nerve among others symptoms and clinical signs caused by compression of the median nerve within the carpal tunnel.

What are some muscular diseases?

What is atrophy of the muscles?

Muscle atrophy is the wasting (thinning) or loss of muscle tissue.

Where is the interosseus muscle located?

Atrophy of the interosseus muscles (including the palmar interossei that lie on the anterior aspect of the metacarpals, the dorsal interosseus muscles of the hand, which lie between the intercarpals, the plantar interosseus muscles, which lie underneath the metatarsal bones, and the dorsal interossei, which are located between the metatarsal bones.

What is interosseous muscle atrophy in multiple myelopathy?

Interosseous muscle atrophy. Skeletal metastases are most commonly seen in breast, lung, prostatic cancers and multiple myeloma, and neuropathic symptom will occur when spinal cord and vertebra are involved. Accurate diagnosis of malignancy-related cervical myelopathy will depend on detailed physical and neurological examinations.

What is the treatment for interosseous muscle atrophy of left hand?

The patient subsequently received local spinal irradiation, monthly zoledronate infusion and oral analgesic treatment with gradual improvement of her neuropathic pain. Figure 1. (A) Remarkable atrophy of interosseous muscle of left hand on physical examination (black arrow).

What is distal spinal muscular atrophy (DSMA)?

Distal spinal muscular atrophy (DSMA), also known as distal hereditary motor neuronopathy (dHMN or HMN), is characterized by distal muscle weakness and wasting without significant sensory involvement. For a general phenotypic description and a discussion of genetic heterogeneity of distal SMA, see HMN1 (182960).
