Anterior temporal area and non-specific facial muscle activity were recorded from 11 patients with unilateral anterior temporal area muscle pain and from 11 matched asymptomatic individuals at various mandibular openings. No significant differences were observed (1) in temporal area EMG activity between pain and non-pain sides and (2) between temporal area and non-specific facial muscle EMG activity between patient and non-patient groups. In relation to increased vertical mandibular opening from centric occlusion: (a) anterior temporal area EMG activity decreased to a minimum level (with further opening, anterior temporal area EMG did not significantly change); and (b) non-specific facial muscle EMG activity decreased to a minimum level (with further opening, non-specific facial muscle EMG increased).

Anterior release and fusion, combined with tong gravity traction and second stage L-rod instrumentation, establishes correctability and accomplishes circumferential arthrodesis of the spine in neuromuscular scoliosis. From March 1979 through April 1982, nine patients with neuromuscular scoliosis, with an average age of 16.4 years, underwent this two-stage surgical procedure. The parameters investigated included correction of scoliotic deformity, correction of pelvic decompensation, and spinal arthrodesis. The preoperative scoliotic curvature measured 81 degrees and the postoperative curve measured 29.3 degrees, an average correction of 63.8%. Pelvic obliquity was significant in five of nine patients, averaging 36.2 degrees preoperatively. Postoperatively the pelvic obliquity averaged 11.8 degrees, an average correction of 67.4%. One of two pelvic fixation rods rotated out of the pelvis of one patient; roentgenographically he appears to have fused without loss of correction. A second patient has a poor fusion mass by roentgenographic criteria, although she has lost no correction and has had no pain. This technique offers results comparable to other series reporting arthrodesis for neuromuscular scoliosis. It has the advantages of requiring no anterior instrumentation and no postoperative immobilization.

Four patients aged 41 to 73 years, who had had rheumatoid arthritis for eight to 25 years, had signs and symptoms of cervical myelopathy and radiculopathy due to either atlantoaxial dislocation with herniation of the odontoid through the foramen magnum, or subluxation of the middle to lower cervical vertebrae. Spastic paraparesis or quadriparesis, severe nuchal immobility and pain, and flaccid paresis of the upper limbs necessitated anterior medullary decompression and posterior cervical fusion. Postmortem examination disclosed old ischemic necrosis, atrophy, and gliosis in the low medulla and cervical cord. Anterior and posterior gray horns and contiguous posterior and lateral funiculi bore the brunt of the damage. Ascending and descending wallerian degeneration and atrophy of the cervical nerve root were evident. In three cases, anterior spinal or radicular arteries demonstrated intimal fibrosis with moderate stenosis; two cases depicted chronic phlebitis or subarachnoid vessels. Previous reports have infrequently provided evidence of a vasculopathy.

Metastatic lesions involving the spine may cause vertebral body collapse, resulting in either spinal instability or neural compression, or both. Progressive destruction of the vertebral body by the tumor may cause increasing spinal instability, leading to a kyphotic deformity and further neural deficit. Anterior decompression allows direct excision of the tumor focus and direct neural decompression. Because of postoperative irradiation, conventional bone grafts are rarely incorporated. Over an 8-year period, 52 patients with spinal instability secondary to metastatic pathological fractures of one or more vertebrae underwent anterior decompression and stabilization by replacement of the affected vertebral bodies with methyl methacrylate, polymerizing in situ. No postoperative external support was required, and the acrylic fixation achieved by this method was not affected adversely by subsequent irradiation to a mean of 4020 rads. Forty patients had major neurological impairment preoperatively and required anterior spinal cord and/or nerve root decompression prior to fixation. Of these, 21 had complete neurological recovery postoperatively, 13 others were improved significantly, five remain unchanged, and one patient deteriorated neurologically. There were three cases with failure of fixation. Seven other patients did not benefit from the procedure because of specific complications or the advanced state of their disease. The remaining 42 patients had good relief of pain and restoration of spinal stability, which did not deteriorate during the follow-up period, ranging from 6 to 100 months postoperatively.

The anterior spinal artery syndrome in three patients is described and from the literature 60 additional patients were collected. Motor recovery in the following groups of patients was noted: (1) Partial loss of motor function and pain sensation--70.4 per cent (19/27); (2) Complete motor loss but partial loss of pain--83.3 per cent (5/6); (3) Paresis but pain sensation absent--66.7 per cent (6/9); and (4) Absent motor function and pain--38.9 per cent (7/18). Motor recovery was also found to vary according to aetiology: (A) Unknown cause--92.9 per cent (13/14); (B) Post-infection or vaccination--88.9 per cent (8/9); (C) Anterior spinal artery occlusion--33.3 per cent (3/9); (D) Spinal cord angioma--20 per cent (2/10); and (E) Aortic lesion--20 per cent (1/5). Patients with sparing of motor function or pain sensation below the lesion do better than those without both functions. Neurological return also varies with the aetiology of the syndrome.

A simplified arthrotomographic technique has been performed successfully in more than 200 patients with symptoms referable to the temporomandibular joint. Soft-tissue abnormalities not detected by plain film radiography were demonstrated. Anterior meniscus displacement was the most significant finding in patients with unilateral pain and limitation of opening. New arthrographic observations and research imaging methods, including CT-assisted arthrography, are described. Leakage of contrast material along the lateral condylar neck in patients with anterior meniscus displacement suggests associated tearing of the lateral capsular attachment. Our results confirm that arthrography is a useful diagnostic procedure for suspected internal derangements of the temporomandibular joint.

The results of the use of Harrington rods in the treatment of spinal fractures were reviewed. It was found that with burst fractures where the anterior pillar was deficient there was a significant incidence of loss of reduction. Anterior bone supplementation is recommended in these fractures when major loss of height or angulation occurs. Several technical faults were detected which, in most cases, also led to a loss of reduction. Almost all patients with an anatomical reduction were free of pain. There was no correlation between the loss of reduction and the lapse of time before operation, the levels of instrumentation, the length of the fusion, the severity of the initial deformity, the degree of initial correction or the presence or absence of a neurological deficit.

The clinical presentation, investigative findings, classification, and management of 17 acute pseudotumors based on patterns of orbital involvement is presented. Acute pseudotumors developed over days to weeks and were dominated by pain, neuropraxia, and inflammatory clinical features. Five patterns of acute inflammatory pseudotumor were seen. Anterior and diffuse acute pseudotumors were characterized by manifestations of inflammation of the globe and orbit including pain, lid swelling, ptosis, diplopia, uveitis, papillitis, optic neuropathy, and exudative retinal detachment. Anterior or diffuse orbital infiltration was noted on computerized tomography (CT) and ultrasound. Lacrimal involvement was characterized by local pain, tenderness, lid swelling and inflammation, with CT and ultrasound confirming an anterior inflammatory mass. Posterior or apical involvement led to an early optic neuropathy, and myositic lesions were characterized by features of muscle infiltration. Management with steroids was effective and could be followed by serial CT studies.

Visual field loss was the presenting symptom in 19 patients with large intracranial aneurysms of the carotid system. Location of the aneurysm was cavernous, carotid-ophthalmic (two), supraclinoid (nine), anterior communicating (six). Other features were pain and a long history of fluctuating visual loss. Cavernous or carotid-ophthalmic aneurysms mostly caused purely uniocular field loss consistent with optic nerve compression. Supraclinoid aneurysms most often caused a lateral chiasmal syndrome. Anterior communicating aneurysms caused asymmetric compression of one or both optic nerves, the eye contralateral to the feeding artery being more often affected. Carotid ligation appeared to arrest visual deterioration in some patients in the supraclinoid group.

Local recurrence of rectal cancer develops in the posterior bony pelvis as an isolated event in about half of the patients with recurrence. Although radiation can palliate sacral root pain, the disease is usually progressive and is rarely amenable to conventional resection. We have adapted a surgical technique usually used for primary sacral tumors, which permits a complete en bloc excision of recurrent rectal cancer in most instances. This approach consists of a laparotomy with pelvic dissection and mobilization of structures to be resected. The patient is repositioned prone and the posterior pelvis (sacrum and side walls) is then resected with preservation of appropriate nerve roots of the posterior pelvis and the sciatic nerve. Reconstruction is done with muscle and skin flaps. We have done 21 such procedures, of which, 11 were for pelvic recurrence of rectal adenocarcinoma. Seven patients had resections for cure and four had palliative resections of fungating or infected tumors. All but one patient was postabdominal perineal resection and nine patients had been irradiated (3000-9000 rads). Two patients had received up to 9000 rads in separate courses (external beam in one and interstitial radiation in the other). The posterior extent of resection was S1-2 to 5 in six patients; S3 to 5 in three patients, and S4-5 in two patients. Anterior exenteration was performed in three patients and three patients had additional resection of other organs. In the curative resection group, three patients are living free of disease at six, ten, and 52 months, and one patient was NED at 60 months, but has again had tumor recurrance and is living with disease at 65 months. One patient died of disease at 13 months and one patient died of a pulmonary embolus following resection for ureteral obstruction at five months. One postoperative death occurred from a cerebrovascular accident at 52 days. In the palliative resection group, three patients survived with relief of local tumor symptoms four, eight, and 12 months. One patient who had received a total of 9000 rads developed flap necrosis, small bowel fistula and died 60 days after resection. Although this is a small series, it suggests that abdominal sacral resection of locally advanced pelvic cancer is feasible and may provide good palliation in most and possible cure in some patients who develop recurrence after primary resection of adenocarcinoma of the rectum.
