Brain computed tomography (CT) is a useful tool for evaluating the pathologic findings in the brains of children with neurologic abnormalities. Brain CT investigation and the Munchner Funtionelle Entwicklungs Diagnostik (MFED) developmental assessment was performed in 88 patients with spastic cerebral palsy. The incidence of abnormal brain CT findings in patients with spastic cerebral palsy was 69.3%. The group with pathologic CT findings had a greater possibility of having developmental delay than the group with normal CT findings (p < 0.05). However, there was no significant relationship between the specific MFED categories and the types of brain CT abnormalities. Pathological CT findings could offer important prognostic information indicating a higher risk concerning the grade of developmental delay.

OBJECTIVE: To evaluate whether 7 radiographic angles make a useful method for analysing foot deformities in children with cerebral palsy, and to assess with changes in angles after 2 years with orthoses or operations. METHOD: The talocalcaneal, talus-first metatarsal, and calcaneus-fifth metatarsal angles on the AP radiographs and the talocalcaneal, tibiotalar, talus-first metatarsal, and talohorizontal angles on the lateral radiographs were measured in 183 cerebral palsied. Seven angles were analyzed according to the clinical types, spasticity, ambulation, and age. One hundred three feet were followed up for 2 years with application of orthoses or operations. RESULTS: The frequencies of higher range in AP talocalcaneal angle were 24.4% in spastic diplegia. The increased frequencies for abnormal range increased as the grade of spasticity. Non-ambulator group had many frequencies of lower range in AP talocalcaneal angle. The age of 8~9 years showed high peak in the frequency of abnormal range. After 2 years, the frequencies of normal range were increased in groups with orthoses or operations. CONCLUSION: The radiographic angles were a useful method for observing feet of the children with cerebral palsy. If the appropriate interventions for feet were applied, the normal frequencies of radiographic angles were increased after 2 years.

OBJECTIVE: To study the incidence and degree of the cervical instability in the cerebral palsied patients and to investigate the cause of the high incidence of cervical myelopathy in these patients. METHOD: The static and dynamic radiography of the cervical spine in the sagittal plane was performed in seventy-two patients with athetoid and spastic cerebral palsy and the incidence of spondylolisthesis, range of motion(by the Penning Method), sagittal diameter of the cervical canal, and posture of the cervical spine were evaluated. RESULTS: The incidence of the cervical spondylolisthesis was fifty percent with athetoid cerebral palsy and twenty-seven percents with spastic cerebral palsy. The incidence of spondylolisthesis was especially high at the level of C3/4 and C4/5. The excessive range of motion in flexion/extension by the sagittal plane was observed in 66.7% of athetoid patients and 53.3% of spastic patients, especially at the C2/3 and C3/4 levels. The abnormal curvature was noted in 66.6% of athetoid and spastic patients. C-curve and S-curve were more common in athetoid patients and straightening of the C-spine was more common in spastic type. A sagittal diameter of the cervical spinal canal was significantly decreased in patients with athetoid patients with C3/4 spondylolisthesis and/or abnormal curvature such as a C-curve or S-curve(P<0.05). Height of the vertebral body was decreased in both athetoid and spastic patients. CONCLUSION: The combination of a cervical instability and a narrow spinal canal predisposes the neurological progression to a cervical myelopathy in cerebral palsied patients.

PURPOSE: To review the results of resections of heterotopic ossification around the hip in patients with central nervous system injuries. MATERIALS AND METHODS: Heterotopic ossification was resected in ten hips of eight patients and followed for at least one year. Average age was 38.1 years (range, 21-56 years). We reviewed the charts and the radiographs for overall patient function, location of the lesion, radiographic evidence of maturation and any recurrence. Heterotopic ossification was resected regardless of the result of bone scan. RESULTS: All patients showed improved function. Three minimal recurrences and one moderate recurrence were identified at the last follow-up radiography, but the range of motion had not decreased due to recurrence. CONCLUSION: Severe heterotopic ossification around the hip in patients with spastic paralysis was resected, and it was found that the range of motion was improved in all patients and that the chance of recurrence was minimal, even though the bone scan showed hot uptake on the bone scan.

BACKGROUND: There are no reports of the pressure changes across the foot after extraarticular subtalar arthrodesis for a planovalgus foot deformity in cerebral palsy. This paper reviews our results of extraarticular subtalar arthrodesis using a cannulated screw and cancellous bone graft. METHODS: Fifty planovalgus feet in 30 patients with spastic diplegia were included. The mean age at the time of surgery was 9 years, and the mean follow-up period was 3 years. The radiographic, gait, and dynamic foot pressure changes after surgery were investigated. RESULTS: All patients showed union and no recurrence of the deformity. Correction of the abduction of the forefoot, subluxation of the talonavicular joint, and the hindfoot valgus was confirmed radiographically. However, the calcaneal pitch was not improved significantly after surgery. Peak dorsiflexion of the ankle during the stance phase was increased after surgery, and the peak plantarflexion at push off was decreased. The peak ankle plantar flexion moment and power were also decreased. Postoperative elevation of the medial longitudinal arch was expressed as a decreased relative vertical impulse of the medial midfoot and an increased relative vertical impulse (RVI) of the lateral midfoot. However, the lower than normal RVI of the 1st and 2nd metatarsal head after surgery suggested uncorrected forefoot supination. The anteroposterior and lateral paths of the center of pressure were improved postoperatively. CONCLUSIONS: Our experience suggests that the index operation reliably corrects the hindfoot valgus in patients with spastic diplegia. Although the operation corrects the plantar flexion of the talus, it does not necessarily correct the plantarflexed calcaneus and forefoot supination. However, these findings are short-term and longer term observations will be needed.

Mycoplasma pneumoniae (MP) infection can result in extrapulmonary and respiratory manifestations. The direct invasion by MP and the indirect invasion by immune-mediated response have been suggested as the pathogenesis of extrapulmonary manifestations. Neurologic manifestations are the most common among the extrapulmonary manifestations associated with MP infection. We report the case of a 4-year-old previously healthy boy with encephalitis accompanied by MP pneumonia. The patient's respiratory manifestations appeared 14 days before the neurological manifestations. Leukocytosis was observed in the patient's cerebrospinal fluid, but the result of the MP polymerase chain reaction was negative. The magnetic resonance imaging of the patient's brain showed high signal intensity at bilateral basal ganglia. The chest radiograph confirmed the presence of lobar pneumonia. The serological test on MP-specific immunoglobulin M titer revealed a positive result. The clinical course improved with the administration of immunomodulatory therapies, but the patient subsequently developed spastic quadriplegic cerebral palsy. MP is a common pathogen in children and may induce aggravating neurologic diseases. Thus, MP should be considered a causative agent of encephalitis in children. Immunomodulatory drugs are the recommended therapeutic option for severe MP encephalitis.

OBJECTIVE: To find factors affecting hip and femoral deformities in children with spastic cerebral palsy (CP) by comparing various clinical findings with imaging studies including plain radiography and computed tomography (CT) imaging. METHODS: Medical records of 709 children with spastic CP who underwent thorough baseline physical examination and functional assessment between 2 to 6 years old were retrospectively reviewed. Fifty-seven children (31 boys and 26 girls) who had both plain radiography of the hip and three-dimensional CT of the lower extremities at least 5 years after baseline examination were included in this study. RESULTS: The mean age at physical examination was 3.6 years (SD=1.6; range, 2–5.2 years) and the duration of follow-up imaging after baseline examination was 68.4 months (SD=22.0; range, 60–124 months). The migration percentage correlated with motor impairment and the severity of hip adductor spasticity (R1 angle of hip abduction with knee flexion). The femoral neck and shaft angle correlated with the ambulation ability and severity of hip adductor spasticity (R1 and R2 angles of hip abduction with both knee flexion and extension). CONCLUSION: Hip subluxation and coxa valga deformity correlated with both dynamic spasticity and shortening of hip adductor muscles. However, we found no correlation between femoral deformities such as femoral anteversion, coxa valga, and hip subluxation.
