Cervical spondylotic radiculopathy producing motor manifestations mimicking primary muscular atrophy.

Cervical radiculopathy unaccompanied by pain or sensory disorder but manifested only by paresis, atrophy, fasciculation, and reflex loss is unusual. Three such cases are presented. Considerable diagnostic difficulty may arise in distinguishing patients presenting with these features from those who have primary motor neuron disease. Two additional case reports demonstrate that this distinction is not always possible. Diagnosis, management, and prognosis are discussed. Differentiation between motor neuron disease and spondylosis will avert needless surgery in the former group and will result in beneficial, sometimes curative surgery in the latter group.

Evaluation of cervical spine surgery by postoperative myelography.

After spontaneous remission of nerve root compression, a myelographic defect may persist. Similarly, myelopathy may remain nonprogressive for long periods despite appreciable myelographic deformity. Although operation may arrest or improve the symptoms of cervical disc lesions and spondylosis, the ultimate confirmation that entrapped neural elements have been relieved permanently can only be provided by postoperative myelography. Preoperative and postoperative myelography documents the significant improvement that can be achieved by using posterolateral and posterior approaches to the cervical spine in patients with nerve root or spinal cord compression. The results in this group of patients were achieved with none of the disadvantages or complications of cervical spine fusion or of the interbody removal of cervical disc tissue, also leading to cervical fusion.

Lumbar synovial or ganglion cysts.

Most reports regarding synovial cysts of the spinal canal have been presentations identifying an unusual pathological entity that is to be included in the differential diagnosis of cauda equina compression syndromes. Most of the 26 cases reported represent isolated examples of this pathological process. We present five cases of lumbar synovial cysts encountered in our practice in the past 8 years. Patients with lumbar synovial cysts do not demonstrate any predictable clinical picture. They may present with a unilateral sciatica or neurogenic claudication. Lumbar extension is usually restricted, whereas flexion is full. Mechanical signs of nerve root entrapment or lumbosacral plexus irritation are unimpressive. Neurological deficits are usually mild, if present. Radiological findings include degenerative spondylosis, spondylolisthesis, and a rounded posterolateral extradural mass of low attenuation value adjacent to a facet shown on computed tomographic scan. The etiology of lumbar synovial cysts is not known. Histological findings of myxoid degeneration, microcystic change, calcification, and hemosiderin deposits suggest that chronic microtrauma with occasional focal hemorrhage may play a major role in the etiology of the cysts. With resection of the cyst, the postoperative course is usually uneventful. Recurrences have not yet been encountered in our patients.

The abducted arm as a sign of ruptured cervical disc.

A helpful clinical sign of ruptured cervical disc is pain relief upon arm abduction. When the disease process is spondylosis with foraminal stenosis, changing arm position does not relieve pain. Anatomical considerations are discussed.

Cervical myelopathy secondary to movement disorders: case report.

Involuntary cervical movements that result in cervical spondylosis and secondary myelopathy have not been adequately emphasized in the literature. We present two patients with cerebral palsy and long histories of involuntary movements who developed cervical myelopathy. We use these illustrative cases to emphasize that in the presence of underlying neurological symptoms and signs due to advanced cerebral palsy, any recent worsening should provoke a higher index of suspicion for myelopathy. The mechanics of neck movements and surgical treatment are discussed.

Transdural approach to the anterior spinal canal in patients with cervical spondylotic myelopathy and superimposed central soft disc herniation.

We present seven patients with multilevel cervical spondylotic myelopathy and superimposed midline soft disc herniation who were treated by decompressive laminectomies of the spondylotic segments followed by transdural excision of the anteriorly located disc extrusion. There was no perioperative neurological morbidity or mortality associated with this operation, and no patients have developed postoperative kyphotic deformity with an average follow-up of 50.1 months (range, 24 to 87 mo). Two patients had full neurological recovery, whereas five patients had improvement in their preoperative neurological status. We conclude that a posterior transdural approach may offer an alternative surgical option for select patients with multilevel cervical spondylosis with superimposed midline soft disc herniation in whom multiple segment decompression plus access to the anterior spinal canal is necessary.

Vertebral autograft used as bone transplant for anterior cervical corpectomy: technical note.

OBJECTIVE: In this prospective patient study, we used a surgical technique for autograft bone fusion during anterior cervical corpectomy (ACC) in patients experiencing cervical spondylotic myelopathy. We packed the resected bone material of the corpectomy into a titanium mesh cage. To evaluate the efficacy of our autograft technique, we analyzed the results according to neurological outcome, radiological outcome, and complications. METHODS: Between 1995 and 1998, 27 ACC operations were performed for cervical spondylotic myelopathy caused by multisegmental cervical spondylosis. In all patients, decompression of the cervical canal and/or spinal nerve roots was performed by a median cervical corpectomy by an anterior approach. After the ACC was completed, a titanium mesh cage, which was variable in diameter and length, was filled with morselized and impacted bone material from the cervical corpectomy and was then implanted. An anterior cervical plate was placed in all patients to achieve primary stability of the cervical vertebral column. Age, sex, pre- and postoperative myelopathy, number of decompressed levels, radiological results, and complications were assessed. The severity of myelopathy was graded according to the scoring system of the Japanese Orthopaedic Association. RESULTS: Symptomatic improvement of neurological deficits was achieved in 80% of the patients. The mean preoperative Japanese Orthopaedic Association score improved from 13.1 to 15.2 postoperatively (P < 0.05). No patient demonstrated worsening of myelopathic symptoms. Radiological follow-up studies demonstrated complete bony fusion in all patients. A vertical movement of 2.25 +/- 0.43 mm of the titanium cage into the adjacent vertebral bodies was observed in 24 patients. In patients with either a lordotic or neutral cervical spinal axis postoperatively, the axis remained unchanged during the entire follow-up period. CONCLUSION: The results of this study demonstrate that transplantation of autograft bone material harvested during the ACC integrated well in the cage and in the adjacent vertebral bodies. Thus, complications associated with explantation of autograft material from other donor sites, e.g., the iliac crest, could be avoided. The early postoperative and midterm follow-up periods provided no evidence of morphological or functional instability of the operated cervical segments when this autograft technique was used in combination with cervical instrumentation.

Adjacent segment disease: an uncommon complication after cervical expansile laminoplasty: case report.

OBJECTIVE AND IMPORTANCE: Adjacent segment disc disease is a well-described phenomenon that occurs after anterior cervical spinal fusion. One of the advantages of cervical laminoplasty over anterior approaches is that although the treated segments are stiffened, no formal fusion is performed. This is thought to reduce the biomechanical stresses placed on adjacent levels and thus decrease the likelihood of adjacent level degeneration. CLINICAL PRESENTATION: A 62-year-old man presented with myelopathy attributable to cervical spondylosis and underwent a C3-C7 laminoplasty. Improvements in gait were followed 2 years later by symptomatic disc degeneration and spinal cord compression at T1-T2, which rendered him wheelchair bound. INTERVENTION: The patient was treated with a laminectomy at the level of stenosis accompanied by posterior instrumentation and fusion from C5 to T3. This resulted in clinical improvement, and the patient was returned to his baseline ambulatory status. CONCLUSION: Adjacent segment disease is an uncommon complication that occurs after laminoplasty. Careful attention to preserving facet joint motion in the cervical spine may minimize the stresses placed on adjacent motion segments.

Microsurgical cervical nerve root decompression by anterolateral approach.

OBJECTIVE: Cervical radiculopathy caused by a posterolateral soft disc herniation or spondylosis is a common pathology. METHODS: Decompression of a stressed cervical nerve root is a routine neurosurgical procedure. Most of the time it is achieved through an anterior approach and, less frequently, through a posterior approach in specific indications. RESULTS: According to the principles that an anterolateral compression must directly be reached and that working in the vicinity of the vertebral artery is safe under visual control, we developed the anterolateral approach to the cervical intervertebral foramen and the nerve root using a minimally invasive technique to remove the offending process. CONCLUSION: Microsurgical cervical nerve root decompression by anterolateral approach is a minimally invasive technique, permitting one to remove the offending process staightforwardly. The disc and bone resections are minimal. This method avoids osteoarthrodesis or arthroplasty with disc prosthesis. This technique is efficient with good results and low morbidity.

Cervical radiculopathy: pathophysiology, presentation, and clinical evaluation.

Cervical radiculopathy is a common condition that usually results from compression and inflammation of the cervical nerve root or roots in the region of the neural foramen. It is frequently caused by cervical disc herniation and cervical spondylosis. The diagnosis can be established by history and physical examination, but care should be taken, as diagnoses can mimic or coexist with cervical radiculopathy, such as entrapment neuropathies. The pathophysiology, presentation, and clinical evaluation of cervical radiculopathy are discussed.

Cervical corpectomy and strut grafting.

Cervical corpectomy and strut grafting is a deceptively simple procedure that has been performed for many years for a variety of cervical spine disorders (infection, neoplastic disease, and trauma) but most commonly for cervical spondylosis. The procedure requires attention to detail to ensure adequate decompression of the neural structures and avoiding injury to the soft tissues of the neck and the vertebral artery in the transverse foramina. The following description of the technique is one we have successfully used for cervical corpectomy and strut grafting. We also discuss patient selection criteria, avoidance of common complications, and postoperative management.

Mechanical neck pain and cervicogenic headache.

Mechanical neck pain is a very common symptom that may occur with cervical spondylosis. It can be associated with cervical radiculopathy and myelopathy or can occur in isolation. Neck pain can result from a variety of causes, including trauma, tumor, infection, and degeneration. The presentation of axial neck pain varies. This article highlights the presentation, differential diagnosis, and appropriate work-up for the patient who presents with mechanical neck pain.

Is the coned lateral lumbosacral junction radiograph necessary for radiological diagnosis?

The lumbar spine radiographs of 400 orthopaedic outpatients were reviewed to determine if the absence of the coned lateral lumbosacral junction radiograph would lead to a loss in diagnostic accuracy. In 84 (21%) patients the antero-posterior and lateral lumbar spine radiographs failed to visualize adequately the lumbosacral junction. In these patients the coned lateral lumbosacral junction radiograph resulted in 17 (4.5%) diagnoses which would otherwise have been missed. The diagnoses were spondylosis (11), spondylolisthesis (3), spondylolysis (1), Paget's disease (1) and infection (1). Absence of the coned lateral lumbosacral radiograph will result in inadequate demonstration of the lumbosacral junction and a loss in diagnostic accuracy.

[Radiological studies of the cervical spine after laminoplasty by longitudinal splitting of the spinous process].

This study involved a clinical evaluation and radiological follow-up of patients who underwent laminoplasty by longitudinal splitting of the spinous process for compressive myelopathy. The subjects were 47 patients with myelopathy caused by cervical spondylosis or ossification of the posterior longitudinal ligament in the cervical spine. The average age at the time of surgery was 61, and the average follow-up period was 3 years. Overall results: the preoperative score, by the Japanese Orthopaedic Association scoring system, was 9.8, and the postoperative score was 13.9; the average recovery rate was 54.3%. Lateral roentgenograms showed a decreased lordosis in the cervical curvature in 50% of the patients after laminoplasty, especially in those patients where stripping of the attachments of the semispinalis cervices to the spinous process of C2 occurred. The recovery rate was good in patients with postoperative lordotic or straightened necks (61.1% and 55.0%, respectively), but it was poor in those with kyphotic or S-shaped necks (average: 36.1%). The postoperative range of motion of the cervical spine had decreased to 43% of the preoperative range.

Potentially fatal asphyxia following a minor injury of the cervical spine.

The case is reported of an elderly man with asymptomatic cervical spondylosis who sustained a minor hyperextension injury of the cervical spine when the brakes of a car were applied suddenly to avoid a collision. Within six hours marked swelling of the neck and severe dyspnoea developed, and a lateral radiograph showed the pharyngeal shadow displaced far forwards and a crack fracture of an anterior osteophyte. Tracheostomy and evacuation of a massive prevertebral haematoma were performed, with immediate relief. The case draws attention to the possibility of this serious complication of a "whiplash" type of injury.

The natural history of congenital disease of the hip.

Fifty-four adults with eighty hips affected by congenital disease which had not been treated have been reviewed. Fifty-nine per cent of forty-two dislocated hips had fair or poor grading scores. The incidence of osteoarthritis was markedly increased in the presence of a well-developed false acetabulum. Unilateral dislocation led to valgus deformity and degenerative changes in the ipsilateral knee in seven of twenty-two patients. Dislocation did not increase the incidence of symptomatic lumbar spondylosis. The height of the dislocated head on the ilium was not found to be related to the prognosis for the hip, the knee or the lumbar spine and did not correlate with the development of the false acetabulum. Frank congenital subluxation eventually led to osteoarthritis of the hip.

The prognosis of neck injuries resulting from rear-end vehicle collisions.

Injury of the neck may result when a motor vehicle is run into from behind; such injury is frequently the cause of prolonged disability and litigation. We report a series of 61 patients with these injuries. A classification, based upon the presenting symptoms and physical signs has been evolved. This classification is shown to be a reliable basis for formulating a prognosis. Factors which adversely affect prognosis include the presence of objective neurological signs, stiffness of the neck, muscle spasm, and pre-existing degenerative spondylosis.
