We investigated the question as to whether transcranial magnetic stimulation of nerve structures can be used to obtain an objective description of motor impairment in humans with cervical nerve root compression or myelopathies. We were able to show that paresis is correlated with an increase in the latency of the evoked muscle potentials. Application of the method in the fields of orthopaedics and neurosurgery permits a description of motor deficits in cervical compression radiculopathy and myelopathy. Although the value of the method for orthopaedic and neurosurgical purposes is not yet completely clear, our experience does indicate interesting possibilities in the diagnostic evaluation of diseases of the cervical spine.

Dissociated motor loss due to cervical spondylosis and disc herniation was evaluated in 10 patients who presented with left deltoid paresis in the absence of sensory deficits or myelopathy. All of these cases underwent cervical anterior decompression. Based on magnetic resonance imaging, computed tomography myelography, and computed tomography discography, patients were divided into two pathologic types: The first showed focal bony spur and disc herniation with axial cord rotation and nerve root compression, and the second demonstrated ventral cord flattening. Electrophysiologic studies included evoked spinal potentials, motor evoked potentials, and evoked muscle action potentials. Motor evoked potentials, recorded epidurally from the ventral aspect of the thecal sac and the nerve root within the anterior discectomy or vertebrectomy sites, proved clinically most useful. Combining the latest available neuroradiologic and electrophysiologic information, 4 types of neural injury associated with deltoid pareses were identified in the 10 patients. The first included isolated C5 nerve root lesions; the second, C6 nerve root lesions; the third, both C5 and C6 nerve root lesions, and finally, intrinsic cord pathology.

Magnetic stimulation of motor cortex and cervical spinal cord was used to assess motor impairment in patients with either cervical nerve root compression or myelopathy. Evoked potentials were recorded from biceps brachii and abductor pollicis brevis. Our interest centered on whether the paresis resulting from root compression is accompanied by an increased latency of magnetically evoked muscle potentials and whether latency is increased in cases of cervical root compression or myelopathy in which no paresis occurs. Latency increase does appear to be a moderately good indicator of disturbed nerve conduction. In particular, prolonged latencies in cases of "subclinical" paresis could be used as an important diagnostic tool for the early detection of motor deficits in cervical compression radiculopathy and myelopathy.

We were interested in the question, if transcranial magnetic stimulation of nerve structure can be used in the objective description of motor impairment in humans with cervical nerve root compression and myelopathies. We could demonstrate, that paresis is combined with an increase of the latency of the evoked muscle potentials. Applications of the method in Orthopaedics and Neurosurgery involve description of motor deficits in cervical compression radiculopathy and myelopathy. Although the value of the method for orthopaedic and neurosurgical purposes is not yet clear, our experiences indicate interesting diagnostic possibilities in cervical spine diagnostics.

Ganglionic and synovial cysts (juxta-facet cysts) causing nerve root compression are very rare. Magnetic resonance imaging is the best means of diagnosis. The treatment of choice is surgical removal of the cysts, though spontaneous remissions do occur. CT-guided aspiration of the cysts and corticosteroid injection can lead the symptoms to disappear, but only for a short time. In a retrospective study covering a period of 16.5 years, we discovered 24 juxta-facet cysts (10 ganglionic and 14 synovial cysts) with clinical symptoms in a total of 19,107 lumbar and thoracic operations performed to relieve nerve root compression: 16 cysts were located at the level L4-5,3 at the level L5-S1,2 at L3-4, and 1 each at the levels L2-3, L1-2, and T10-1. Seven patients complained of radicular pain, and the other 17 patients also had neurological deficits. Fourteen cysts were resected, and in 10 cases the lumbar disc was removed simultaneously. The average follow-up in 23 of the 24 patients was 26.6 months. Most (74%) of the patients became free of pain. Pareses disappeared in 89% and sensory deficits in 73% of cases.

Viral invasion of the motoneurons and the subsequent inflammation in the anterior horn cells by the varicella zoster virus results in a weakness in the area of the cutaneous eruption. The exact mechanism of zoster paresis is uncertain. The occurrence of symptoms resembling complex regional pain syndrome (CRPS) is common in subjects where the herpes zoster (HZ) outbreak affects an extremity, particularly if it is the distal extremity that is involved. We report the case of a 54-year-old man with monoparesis, hyperalgesia, allodynia, edema, and both color and skin-temperature changes in his left arm after a skin eruption. Electrophysiologic examination revealed the partial degeneration of the superior, middle, and inferior truncus in the brachial plexus, with evidence of HZ infection. Magnetic resonance imaging of the cervical spine and brachial plexus showed degenerative changes without any evidence of nerve root compression. Brachial plexopathy may be the direct cause of the reversible upper-limb paresis resulting from HZ with CRPS-like symptoms.

Although spinal osteochondromas can cause various clinical signs, the spinal cord or nerve root compression by solitary lumbar osteochondromas are rare clinical entities. We present a 62-year-old female patient with lower-back pain, progressive left leg paresis, numbness on the both lower extremities and urinary incontinence. The patient's clinical picture made us suspect the possibility of cauda equina syndrome. Radiological examination revealed a lesion originating from the left inferior articular facet of the second lumbar vertebrae. Urgent surgical decompression was performed and the lesion was removed totally. Histopathological examination confirmed the diagnosis of benign osteochondroma.

Neonatal cervical osteomyelitis is extremely rare, with only a few cases having been reported. We report a neonate with cervical osteomyelitis and extensive inflammation of the surrounded tissues that caused nerve root compression and upper limb paresis.

OBJECTIVE Various neurological diseases are known to cause progressive painless paresis of the upper limbs. In this study the authors describe the previously unspecified syndrome of compression-induced painless cervical radiculopathy with predominant motor deficit and muscular atrophy, and highlight the clinical and radiological characteristics and outcomes after surgery for this rare syndrome, along with its neurological differential diagnoses. METHODS Medical records of 788 patients undergoing surgical decompression due to degenerative cervical spine diseases between 2005 and 2014 were assessed. Among those patients, 31 (3.9%, male to female ratio 4.8 to 1, mean age 60 years) presented with painless compressive cervical motor radiculopathy due to neuroforaminal stenosis without signs of myelopathy; long-term evaluation was available in 23 patients with 49 symptomatic foraminal stenoses. Clinical, imaging, and operative findings as well as the long-term course of paresis and quality of life were analyzed. RESULTS Presenting symptoms (mean duration 13.3 months) included a defining progressive flaccid radicular paresis (median grade 3/5) without any history of radiating pain (100%) and a concomitant muscular atrophy (78%); 83% of the patients were smokers and 17% patients had diabetes. Imaging revealed a predominantly anterior nerve root compression at the neuroforaminal entrance in 98% of stenoses. Thirty stenoses (11 patients) were initially decompressed via an anterior surgical approach and 19 stenoses (12 patients) via a posterior surgical approach. Overall reoperation rate due to new or recurrent stenoses was 22%, with time to reoperation shorter in smokers (p = 0.033). Independently of the surgical procedure chosen, long-term follow-up (mean 3.9 years) revealed a stable or improved paresis in 87% of the patients (median grade 4/5) and an excellent general performance and quality of life. CONCLUSIONS Painless cervical motor radiculopathy predominantly occurs due to focal compression of the anterior nerve root at the neuroforaminal entrance. Surgical decompression is effective in stabilizing or improving motor function with a resulting favorable long-term outcome.
