Metabolic profiles in patients with acute neurosurgical injuries.
Twenty-seven patients with acute neurosurgical injuries were compared with 23 patients with neurosurgical and multisystem injuries and 10 patients with multi-system injuries without neurosurgical injuries. Patients with isolated acute neurosurgical injuries did not demonstrate a hypermetabolic state with increased loss of nitrogen and decreased circulating levels of albumin, prealbumin, and retinol-binding protein when compared to multisystem-injured patients. Patients with demonstrated hypermetabolism on day 1 were supported with parenteral nutrition which decreased their protein losses and stabilized other metabolic variables such as calcium and phosphorus. It is concluded that patients with neurosurgical and other multisystem injuries require close metabolic monitoring. Early institution of metabolic support in hypercatabolic patients may prevent clinically significant depletion states.

Occipital neuralgia and the C1-2 arthrosis syndrome.
Occipital neuralgia syndromes have been ascribed to a great many pathological alterations, some demonstrable and some hypothetical. Recently, occipital neuralgia has been attributed to developmental and posttraumatic lesions in the cervicocranial junction region, with the nerve roots at C-1 and C-2 considered to be the principal pain pathways. The authors describe a series of seven patients with an upper neck and occipital pain syndrome due to unilateral degenerative disease (arthrosis) of a C1-2 lateral articulation. Two of the cases are presented in detail. This disease is demonstrable by radiography through the open mouth by isotope bone scanning, and by computerized tomography scanning. Temporary relief may be obtained by anesthetic and steroid injection, and permanent relief achieved by C-2 dorsal rhizotomy.

Spinal arachnoiditis. The postoperative variety in particular.
The diagnostic and therapeutic courses of 68 patients with the discharge diagnosis of spinal arachnoiditis were reviewed. The combination of oil myelography and spinal surgery was the probable cause of arachnoiditis in almost all cases. The clinical presentation featured leg pain (90%), low-back pain (80%), and sphincter disturbance (25%). Motor, sensory, and reflex changes were present in two thirds of the cases, with a majority having defects attributable to bilateral or multiple root level involvement. Specific analysis of previous operative procedures cerebrospinal fluid (CSF) studies, and myelographic patterns did not disclose any consistent correlation with the clinical presentation. Results are interpreted in light of prior clinical and experimental studies on the reaction of the meninges to trauma and myelography.

Instrumentation of the spine for fracture dislocations in children.
13 children, ages 11-16 years, sustained severe compression fractures or fracture dislocations of the thoracolumbar spine. All cases were treated with Harrington instrumentation with fusion and six also had decompressive laminectomy. All injuries had significant instability and neurologic deficits (nine complete). Follow-up of 2-10 years is provided for analysis of maintenance of reduction and neurologic improvement. This technique appears to offer stability, reduction of orthopedic defects, and assumption of a more aggressive rehabilitation program without introducing significant operative morbidity or neurologic deficit.

Degenerative lumbar scoliosis.
Recent work on degenerative lumbar curves has focused on stable deformities with entrapment syndrome secondary to spondylotic compression. A review of our local experience with degenerative lumbar curves shows that approximately half of the 14 cases have had a less typical radiographic presentation of short reciprocating lumbar curves thought to be on the basis of asymmetric intervertebral osteochondrosis. In these latter cases, marked spondylotic ridging and intervertebral buttressing were absent; therefore, major decompressive surgery on the residual posterior elements may increase instability and hasten further collapse. Although most patients have had good relief of radicular leg complaints with decompressive procedures, several patients had persistent low-back pain that appeared to have a mechanical basis. In those instances of potentially increased postoperative instability or persistent mechanical back complaints, consideration should be given to augmenting decompressive procedures with Harrington instrumentation and fusion for these painful collapsing lumbar spines.
