Idiopathic cortical hyperostosis.

Infantile cortical hyperostosis (Caffey-Silverman syndrome) is an uncommon and not well-understood disorder. Most authors confine cortical hyperostosis strictly to infants under six months of age as originally described by Caffey. Others indicate they have seen the same clinical, radiographic, and pathologic problem in older children as initial presentations or as a recurrence where the infantile phase had possibly been unrecognized. This is a report of idiopathic cortical hyperostosis (ICH) in an 11-year-old girl who had no history of the disorder as an infant. The report confirms others who have documented cortical hyperostosis in older children and postulates that it is the same entity as infantile cortical hyperostosis.

The wake-up technique as a dual protector of spinal cord function during spine fusion.

Intraoperative awakening is commonly used to evaluate voluntary motor function to lessen the risks of nerve damage during posterior spine fusion and Harrington rod instrumentation for idiopathic scoliosis. This is a report of intraoperative monitoring of tension in the soft tissues of patients with idiopathic scoliosis utilizing a strain-gauged distraction outrigger. The tension in soft tissues was found to drop following intraoperative awakening by an average of 52 N in the 14 patients monitored. The "wake-up" technique may aid in protecting the spinal cord from overdistraction by the increase in soft tissue tension present at the time of Harrington rod replacement in addition to providing a spot check of motor function. This increased tension may slightly repress curve correction.

Evaluation of physical therapy service for severely mentally impaired students with cerebral palsy.

The effects of two types of physical therapy service were studied over a five-month period in 19 severely mentally impaired cerebral palsied students aged 3 to 22 years. The students were paired and assigned to either a direct therapy treatment group or a supervised therapy management group. Ten similar students in a comparison group received no physical therapy. The study showed no significant difference in development of mature developmental reflexes, improvement of gross motor skills, or increase of passive joint motion among similar students placed in the direct, supervised, and comparison groups. This pilot study is not intended to decide the issue of physical therapy for these students. It does, however, indicate that objective tests may be used reliably to measure three major areas of sensory motor development. More extensive and longer-term studies are needed to determine the most beneficial form of physical therapy for this double-disability population.

C2--C3 dislocation in a child.

This is a case presentation of an occurrence of a C2--C3 dislocation without fracture occurring in a child, probably at the time of birth, causing weakness and hypotonia and going unrecognized for almost 2 years. Surgical stabilization provided a slow improvement in neurologic function. Cervical spine injury should be an initial diagnostic consideration in the newborn with hypotonia ("congenital myopathies" and "floppy infants"), since discovery of remediable lesions early could make stabilization therapy effective.

Congenitally absent thoracic pedicle in a child with rhabdomyosarcoma.

A case of congenital absence of a thoracic pedicle is reported in a 9 year old boy with embryonal rhabdomyosarcoma of the eyelid. In this clinical setting a surgical exploration was necessary in order to differentiate a developmental anomaly from an acquired metastatic deposit.

Os Odontoideum.

A review of the cases of thirty-five patients with os odontoideum, the largest series reported to date, supports the concept that trauma is the etiology of the abnormality. Most of the patients had roentgenographic instability of the affected spinal segment, and were treated with spine fusion. Eleven patients had lesions attributable to injuries received before they were four years old, although surgical treatment usually was delayed for one to eight years. Nine patients had documented roentgenographic evidence of a normal odontoid process prior to the development of the os odontoideum. Only one-third of the patients had any signs or symptoms indicative of neural deficits, although most patients had cervical pain. Surgical treatment alleviated the pain and instability.

Dorsal defect of the patella with cartilaginous involvement. A case report.

This is a report of a symptomatic cartilaginous defect associated with the dorsal patellar defect. Previously regarded as only an osseous curiosity, this defect can be associated with symptoms of pain after long periods of standing and exercise. Treatment by curettage of the area with debridement of the overlying fibrillated cartliage relieved the pain and produced radiographic evidence of healing of the osseous defect.

Scoliosis and school screening for spinal deformity.

The onset of "idiopathic" scoliosis is gradual. It goes unnoticed by parent and child alike. The problem is often not detected until the curvature has progressed. Severe scoliosis has serious long-term systemic, cosmetic and psychologic effects. School-based screening programs are very effective in reducing the number of operations required. These programs can be carried out by school nurses, physical education teachers and volunteers who are trained by a knowledgeable physician. Brace treatment is successful when scoliosis is detected only.

Congenital anomalies of the odontoid process.

Anomalous development of the odontoid is uncommon, and its clinical significance lies in its potential for producing serious neurologic sequelae due to atlantoaxial instability. Although there are several recognized variations (aplasia, hypoplasia, and os odontoideum), clinically they share the same signs and symptoms, and the treatment is identical. Symptoms are usually due to instability of the atlantoaxial joint, with compression of the spinal cord and anteriorly against the axis or posteriorly from the ring of the atlas. Patients may present with no symptoms, with persistent neck complaints, with transient or permanent neurologic deficits, or with sudden death. Symptoms from cranial nerve irritation seldom occur, but occasionally symptoms of cerebral and brain stem ischemia are noted as a result of compression of the vertebral arteries in the area of the atlas. If the condition is suspected, the diagnosis usually can be confirmed on lateral flexion-extension roentgenograms. Special techniques are often required, particularly lateral laminagrams, and flexion-extension stress roentgenograms are necessary to determine the presence and degree of atlantoaxial instability. The role of prophylactic surgical stabilization is not yet established. If instability greater than 5 mm. is demonstrated or the patient has clinical findings of neurologic compromise, surgical fusion should be performed.

Atlantoaxial rotary deformities.

Persistent torticollis in younger patients, particularly after trivial trauma or an upper respiratory tract infection, suggests a diagnosis of atlantoaxial rotary fixation. The diagnosis can be confirmed by cineroentgenography. Anterior displacement of the atlas, indicating a deficient transverse ligament, should be ruled out by flexion-extension lateral roentgenograms. If conservative management fails to achieve reduction or is followed by a recurrence of the deformity, arthrodesis is indicated.
