Overview

• Median nerve entrapment neuropathy encompasses a spectrum of conditions, including pronator syndrome, which requires consolidated knowledge to improve patient outcomes [1].
• Clear definitions distinguishing recurrence from persistent compression neuropathy are necessary to enable comparison of results across different techniques and clinics [2].
• Agreements on supplementary diagnostics and standardized outcome measurements are needed for upper extremity revision nerve compression surgery [2].
• Diagnosis of mild-to-moderate idiopathic median neuropathy at the carpal tunnel based on signs and symptoms is discordant from diagnosis based on electrodiagnostic studies (EDS) and ultrasound (US) [3].
• There is severe discordance between the estimated prevalence of mild-to-moderate carpal tunnel syndrome based on clinical signs and symptoms (73%) versus EDS and US (51%) [12].
• This discordance calls into question whether clinicians can confidently diagnose patients with mild-to-moderate carpal tunnel syndrome based on clinical presentation alone [12].
• When signs and symptoms suggest mild-to-moderate median neuropathy and surgery is being considered, additional testing such as EDS or US may increase the probability of identifying actual median neuropathy that can benefit from surgery [3].
• Upper-extremity neuropathy can develop following nonupper extremity surgeries, particularly anterior cervical discectomy and fusion (ACDF) [4].
• Neuropathy symptoms following shoulder surgery were often refractory to conservative management [6].
• Surgical decompression for neuropathy following shoulder surgery led to nearly 90% symptom resolution [6].
• Patients with a history of ulnar nerve lesions are at a significantly increased risk of developing carpal tunnel syndrome, especially within the first 2 years [7].
• As the severity of ulnar neuropathy at the elbow increases, the cross-sectional area (CSA) of the ulnar nerve correspondingly increases at the elbow [8].
• Assessment of position and tactile sensations is important in determining participation in manual skills during neuropathy rehabilitation [5].
• Quality of life domains are impacted by distal radius fracture and ulnar neuropathy, with contextual factors influencing these implications [9].

Background & Causes

• Median nerve entrapment neuropathy includes pronator syndrome [1].
• Upper-extremity neuropathy can develop following nonupper extremity surgeries, particularly anterior cervical discectomy and fusion (ACDF) [4].
• Patients with a history of ulnar nerve lesions are at a significantly increased risk of developing carpal tunnel syndrome, especially within the first 2 years [7].
• The anconeus epitrochlearis muscle's contribution to compression neuropathy or protection of the ulnar nerve could not be discerned for the standard population [19].
• A bifid median nerve can cause entrapment by forearm musculature [10].
• The pectoralis minor's unique asymmetric neurologic innervation predisposes the human shoulder to neurologic and musculoskeletal imbalance, producing the Human Disharmony Loop syndrome [18].
• Double entrapment neuropathy of the ulnar nerve at the elbow and wrist may represent double crush syndrome [13].

Symptoms & Presentation

• Median nerve entrapment neuropathy includes pronator syndrome [1].
• Upper-extremity neuropathy can develop following nonupper extremity surgeries, particularly anterior cervical discectomy and fusion (ACDF) [4].
• Neuropathy symptoms following shoulder surgery were often refractory to conservative management [6].
• Patients with a history of ulnar nerve lesions are at a significantly increased risk of developing carpal tunnel syndrome, especially within the first 2 years [7].
• As the severity of ulnar neuropathy at the elbow increases, the cross-sectional area (CSA) of the ulnar nerve correspondingly increases at the elbow [8].
• There is a severe discordance between the estimated prevalence of mild-to-moderate carpal tunnel syndrome based on clinical signs and symptoms (73%) versus electrodiagnostic studies and ultrasound (51%) [12].
• If double crush syndrome is suspected but symptoms are mild, they may respond to conservative treatment [13].
• Assessment of position and tactile sensations is relevant for determining participation in manual skills in patients with upper extremity neuropathy [5].
• Assessing quality of life domains provides insight into the implications of contextual factors on quality of life for patients with distal radius fracture and ulnar neuropathy [9].

Management

• Median nerve entrapment neuropathy reviews aim to consolidate existing knowledge to improve patient outcomes [1].
• Clear definitions of recurrence versus persistent compression neuropathy are needed to enable comparison of results from different techniques and clinics [2].
• Agreements on supplementary diagnostics and standardized outcome measurements are required for comparing results across different techniques and clinics [2].

• Assessing quality of life (QoL) domains for upper extremity conditions provides insight into the implications of contextual factors on QoL [9].
• Surgeons should bear anomalies such as bifid median nerve entrapment by forearm musculature in mind when assessing patients with symptoms of median nerve compression [10].
• Hand abduction tracings are a quantitative outcome measure to follow recovery over time for intrinsic hand function and can be used in patients with severe ulnar neuropathy following surgical intervention [11].
• If double crush syndrome is suspected but symptoms are mild, they may respond to conservative treatment [13].
• In cases of suspected double crush syndrome, invasive treatments should be initiated preferentially at sites with greater clinical suspicion [13].
• Decompressing the deep motor branch of the ulnar nerve caused by heterotopic ossification allowed for spontaneous nerve recovery and reinnervation of ulnar nerve-innervated intrinsic muscles [14].
• More than 50% of patients who did not undergo carpal tunnel release at the initial surgery for perilunate injuries required a release within the follow-up period [15].
• Anterior interosseous nerve transfer, along with cubital and ulnar tunnel release, results in sustained clinical and electrophysiological improvements in patients with severe chronic ulnar nerve compression [16].
• Anterior interosseous nerve transfer combined with cubital and ulnar tunnel release encourages adoption as a standard treatment for severe chronic ulnar nerve compression [16].
• Sensory interventions on motor function, activities of daily living, and spasticity of the upper limb in people with stroke are inexpensive, noninvasive, and easy to perform [17].
• Sensory interventions can be easily implemented into conventional therapy practice in any setting [17].
