Type III syndrome is characterized by neck pain together with radiation to one or more of the following: the medial scapula, chest wall, shoulder area, and head. There may be a vague aching referred to the proximal upper …
December 10, 2021 Double crush syndrome is the phenomenon where there can be 2 distinct compressions along the course of a peripheral nerve. As nerves travel along their path they can be compressed and pinched by various structures.
When there is compression of the median nerve in the wrist as well as compression of the 6th or 7th cervical nerve in the neck, the overlapping symptoms are called "double crush syndrome," and require attention to both the wrist and the neck. A neurologist can determine whether the symptoms are originating in the wrist, the neck, or …
A presentation as such is referred to as double crush syndrome and may mask the presentation of TOS . In these patients, careful consideration of multiple imaging modalities, electromyographic studies, and detailed physical examination are crucial to discern the foci of neurovascular compromise.
For this mechanism of nerve injury-serial compromise of axonal transport along the same nerve fiber, causing a subclinical lesion at the distal site to become …
Double Crush Syndrome. Double crush syndrome is a distinct compression at two or more locations along the course of a peripheral nerve that can coexist and synergistically increase symptom intensity. In addition, dissatisfaction after treatment at one site may be the result of persistent pathology at another site along a peripheral nerve.
When there is compression of the median nerve in the wrist as well as compression of the 6th or 7th cervical nerve in the neck, the overlapping symptoms are called "double crush syndrome," and require attention to both the wrist and the neck.
Background: Double Crush Syndrome (DCS) is a clinical condition that involves multiple compression sites along a single peripheral nerve. The present study aims to …
Several theoretical mechanisms have been proposed based upon the double-crush phenomenon, including neurologic injury from needle or catheter-induced trauma, local anesthetic neurotoxicity, and neural ischemia due to local anesthetic additives.
In the double crush syndrome as postulated by Upton and McComas, the presence of a more proximal lesion does seem to render the more distal nerve trunk more vulnerable to compression. While the exact pathophysiologic mechanism of this interaction is not yet elucidated, it most likely relates to disturbances in axonal flow kinetics and the ...
Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the tibial nerve (TN) within the tarsal tunnel (TT) at the level of the tibio-talar and/or talo-calcaneal joints. ... increase in overlap between patients with peripheral entrapment neuropathy and signs of proximal nerve damage termed double crush syndrome . TTS has been …
Double Crush Syndrome and Anesthetic Implications An additional factor which may contribute to perioperative nerve dysfunction is the phenomenon of the double crush syndrome. This syndrome describes the coexistence of two (or more) clinical or subclinical insults along the course of a nerve.
A potential consequence of performing regional anesthesia in patients with nerve entrapment is what has been termed the "double-crush syndrome." This refers to the enhanced susceptibility of nerves to injury or impairment at one anatomic location when already compressed or otherwise injured at another, separate location.
In 1973, Upton and McComas hypothesized about double crush syndrome (DCS) and reported that "a symptomatic compression at one site predisposed a peripheral nerve to increased susceptibility to impairment at distal location" ( 8 ).
Double crush syndrome (DCS), as it is classically defined, is a clinical condition composed of neurological dysfunction due to compressive pathology at multiple sites along a single peripheral nerve. The traditional definition of DCS is narrow in scope because many systemic pathologic processes, such as diabetes mellitus, drug-induced ...
Double crush syndrome is a controversial diagnosis; some scientists and surgeons believe it is an illness construction that may do more harm than good because it emphasizes an objective pathophysiologic explanation for unexplained symptoms, disability, and dissatisfaction that may be more psychosocially mediated.
Double crush syndrome results from the compression of the same peripheral nerve at two or more levels, which is the cause of a synergistic. For more, visit us.

Abstract. Double crush syndrome is a distinct compression at two or more locations along the course of a peripheral nerve that can coexist and synergistically …
A summary of the key points from this study by Drs. Upton and McComas include: 1) The DOUBLE CRUSH SYNDROME is: serial constraints of axoplasmic …
Double Crush Syndrome (DCS) is a clinical condition that involves multiple compression sites along a single peripheral nerve. The present study aims to describe the epidemiology of DCS and surgical results. Methods
While the double crush most commonly involves carpal tunnel syndrome and C6 (or C8) radiculopathy, it also can involve the ulnar nerve (entrapped at the elbow or less commonly in the hand) and C8 …
Double crush syndrome (DCS) is a clinical condition that involves multiple compression sites along a single peripheral nerve [1], [2]. The literature describes around 20 distinct combinations of nerve fiber lesions.
This example of the same nerve getting pinched at two locations is referred to as "double crush" syndrome. Unfortunately, it's not usually possible to determine which area of compression is causing the most problem, so both areas have to be surgically decompressed. This is one example of double crush syndrome and there are several.
The classic description of double crush syndrome was first described in 1973 by Upton and McComas 4 who theorized that a proximal compression of a peripheral nerve could render the distal peripheral nerve more susceptible to injury due to a disruption in axonal flow or axon transport mechanism.
To further complicate diagnosis, "double crush syndrome" can occur, where nerve irritation occurs in the neck and in the arm. So it's possible to have cervical radiculopathy (a pinched nerve in the neck) and cubital …
The term 'double crush syndrome' originates from work published by Upton and McComas (1973) and as such it would follow established practice if their original statement of the hypothesis were to become the working definition of 'double crush'. The abstract of their paper read as follows:
Double crush syndrome is a controversial diagnosis; some scientists and surgeons believe it is an illness construction that may do more harm than good because it emphasizes an objective...

Double crush syndrome of the thoracic outlet and distal nerve compression that is suspected to be related to chronic maladaptive postural changes, should be treated first with physical therapy and postural modifications. 5.
A phenomenon known as double crush syndrome may increase the susceptibility to injury and symptoms at other locations along the course of the nerve. The purpose of this case report is to describe the physical therapy differential diagnosis and management of a cyclist with upper extremity pain, weakness, and paresthesia.
Background: Double crush syndrome (DCS) of the ulnar nerve, including cubital tunnel syndrome with ulnar tunnel syndrome (UTS), is uncommon. This study compares the postoperative outcomes of patients with isolated ulnar tunnel syndrome versus those with double crush syndrome of the elbow and ulnar tunnel.
Double Crush Syndrome or Carpal Tunnel? Sites of Nerve Compression. Many patients present to our clinic with nerve compression in the wrist. This is often...
How It Happens: Double crush injury may occur in response to low back pain (acute or chronic) caused by pinching of the lumbar nerve root next to the spinal cord.2 The lumbar nerve root injury may lead to compression of any of the nerves farther down in the leg and affect the hip, knee, or ankle.3 In other words, an injury which is originally …
