Fourteen children with spastic
hemiplegia
of various etiology:
cerebral palsy
(seven cases, five with porencephalic cyst); stroke with small deep infarcts (two); hemiconvulsion-
hemiplegia
-epilepsy syndrome (three); traumatic brain injury (two), were investigated by 99mTc-HMPAO SPECT. Localized and remote perfusion abnormalities were studied. Hypoperfusion corresponding to CT abnormalities was found in each group, but the perfusion deficit extended beyond the boundaries of anatomical defects, most prominently in cases with widespread unilateral epileptic discharges. Ipsilateral cerebellar diaschisis was observed in patients with early cerebral insult (who had porencephalic cyst of pre- or perinatal onset) and crossed cerebellar diaschisis was noted in a patient who sustained traumatic brain injury at a later age. Diaschisis in the overlying cortex, thalamus and basal ganglia was noticed in several cases. Although clinical symptoms or signs could not be unequivocally attributed either to the size of the perfusion defects beyond the boundaries of lesions shown by CT or to the diaschisis, the findings may contribute to reveal age-related abnormal perfusion patterns.

If the spasticity of
cerebral palsy
(CP) is reduced in children at a young age by selective dorsal rhizotomy, the incidence of lower-extremity deformities requiring orthopedic surgery may be reduced; however, this has never been investigated in detail. The authors examined the effects of selective dorsal rhizotomy on rates of lower-extremity orthopedic surgery in 178 children with CP. Age at selective dorsal rhizotomy ranged from 2 to 19.3 years (mean 5.5 years) with follow-up intervals ranging from 24 to 70 months (mean 44 months). Spastic CP was classified as quadriplegia (33%), diplegia (65%), and
hemiplegia
(2%). To assess the effects of early versus late rhizotomy on rates of orthopedic surgery, patients were grouped as follows: Group I underwent rhizotomy between 2 and 4 years of age (54 patients), and Group II underwent rhizotomy between 5 and 19 years of age (124 patients). Comparison of Kaplan-Meier plots of lifetime orthopedic surgery rates revealed that Group II underwent orthopedic surgery at a higher rate than Group I (p = 0.037). Analysis by procedure type revealed higher orthopedic surgery rates in Group II than Group I for heel cord releases (p = 0.0025), adductor releases (p = 0.018), and hamstring releases (p = 0.02). Orthopedic surgery rates were no higher for Group II compared to Group I for ankle/foot operations (p = 0.023), femoral osteotomy (p = 0.25), iliopsoas releases (p = 0.35), and "other" operations (p = 0.013). The data indicate that early rhizotomy reduces the need for orthopedic surgery for heel cord, hamstring, and adductor releases.

Cerebral palsy
is caused by a static lesion to the cerebral motor cortex that is acquired before, at, or within 5 years of birth. Multiple causes for the condition exist and include cerebral anoxia, cerebral hemorrhage, infection, and genetic syndromes.
Cerebral palsy
is commonly classified according to the type of movement problem that is present (spastic or athetoid) or according to the body parts involved (
hemiplegia
, diplegia, or quadriplegia). To care for children with
cerebral palsy
, a team approach is most effective; the team should include the pediatrician and orthopedist, among others. In the nonambulatory patient, good sitting posture, the prevention of hip dislocation (spastic hip disease), and the maintenance of proper custodial care are prime concerns. Careful monitoring and treatment of spastic hip disease and the correction of scoliotic spinal deformity are also important. In the ambulatory patient, the main goal is to maximize function. Computerized gait analysis in patients with complex gait patterns helps to show whether orthotic or surgical treatment is indicated. In this paper, we also review both the proper indications for orthopedic intervention in patients with upper extremity involvement and recent methods to control spasticity, such as selective dorsal rhizotomy and administration of botulinum toxin or intrathecal baclofen.

Twenty-three infants with an infarct in the territory of the middle cerebral artery are reported. The diagnosis was made using cranial ultrasound in all, confirmed on postmortem in two cases and on MRI, performed during the neonatal period or in infancy, in 18 of the 20 survivors. Involvement of the main branch was present in 7 cases and three of these had a gestational age of less than 35 weeks. In the other 16 infants, involvement of a cortical branch or one or more of the lenticulostriate branches was present and all but three of these had a gestational age of 34 weeks or less. While involvement of the main branch was usually diagnosed on postnatal day 1 or 2 using ultrasound, involvement of the lenticulostriate branches was noted as a wedgeshaped echogenic lesion in the caudate nucleus, thalamus or putamen, between day 4 up till day 24, and at term age in one of the cases. Neurodevelopmental outcome of those with involvement of the main branch was disappointing as all survivors developed a
hemiplegia
, associated with epilepsy in two; while so far only three of the other 16 infants developed
cerebral palsy
, one a
hemiplegia
and one athetoid
cerebral palsy
. Global delay was present in a further three cases. Infarcts in the region of the middle cerebral artery can occur in both preterm as well as fullterm infants. Involvement of the main branch also occurred in infants with a gestational age below 35 weeks and resulted in the development of a
hemiplegia
in all survivors. Involvement of one of the other branches was especially common in preterm infants, who had a more favourable outcome. As the lesion in the latter group was usually not present before the end of the first week, serial ultrasound up till term age is needed in order to identify these lesions.

The authors studied MR images of the brain in 152 patients, aged 1 to 19 years (mean 3.3), who had spastic
cerebral palsy
(CP) and were attending two hospitals in Japan in 1993 and 1994. Eighty-one patients had diplegia, 45 had quadriplegia, and 26 had
hemiplegia
. Of patients with diplegia, 72 had periventricular leukomalacia (PVL) and very few had other types of lesions. In patients with quadriplegia, three main types of brain lesions were observed: PVL in 12 patients, term-type brain injury in 22, and brain anomaly in 10. In the 26 patients with
hemiplegia
, 17 had a unilateral lesion (rare in patients with diplegia and quadriplegia), and bilateral lesions were seen in seven others.

Among the variable manifesting conditions of neuronal migration disorders, mental retardation, motor disturbance and epilepsy are the main features of developmental disabilities. We analyzed the relationship between clinical symptoms and magnetic resonance (MR) images, including surface anatomy scan (SAS). Thirty nine patients (23 males, 16 females; mean age 6.1 years) with neuronal migration disorders were studied. The diagnoses were
cerebral palsy
in 23 cases, mental retardation in 4. West syndrome in 4, Fukuyama type congenital muscular dystrophy (FCMD) in 6. Walker-Warburg syndrome in 1 and Dubowitz syndrome in 1. Cortical dysplasias were classified into the following 7 groups, mainly based on the SAS findings: complete agyria (AG 1), mixture of agyria and pachygyria (AG 2), bilateral complete pachygyria (BP 1), diffuse pachygyria with marked widening of the bilateral superior frontal gyrus (BP 2), unilateral pachygyria with hemispheric atrophy or hemimegalencephaly UP), focal cortical dysplasia (FP) and other findings such as solitary schizencephaly (Others). Most cases of AG 1 and AG 2 showed spastic quadriplegia (6/7) and symptomatic generalized epilepsy (5/7), whereas cases of BP1 showed spasticity only in 1/8 and epilepsy in 7/8.
Hemiplegia
was observed in 6/7 of UP, 2/8 of FP and 2/4 of Others. Partial epilepsy was observed in 2/7 of UP and 1/8 of FP. Intellectual level was variable in BP 1, UP, FP and Others, but all cases showed severe mental retardation in AG 1, AG 2 and BP 2. BP 2 was observed in all cases of typical FCMD (5/5). The birth weight was less than 2,500 g in 6/7 of UP. The structural findings well correlated with clinical symptoms and epileptic seizure types. The surface anatomy scan was a very useful technique for detecting cortical dysplasias.

The incidence of epilepsy in 323 patients with
cerebral palsy
(CP) was 41.8%. Almost half of the patients with spastic tetraplegia and
hemiplegia
had epilepsy. The incidence was lower in patients with spastic diplegia. No sex differences were observed. Partial seizures were by far the most common form of epilepsy in spastic
hemiplegia
, while generalized tonic-clonic episodes predominated in all other forms of CP. A very high incidence of West syndrome was observed in patients with spastic tetraplegia. Most of the patients with spastic tetraplegia had their first seizure in the first year of life. In patients with spastic
hemiplegia
the onset of epilepsy was often delayed for several years. A high rate of polytherapy was recorded, but two-thirds of the patients remained seizure-free for long periods. In just over one-fifth of the patients successful withdrawal of medication was achieved.

We describe a 42-year-old man with right
hemiplegia
from
cerebral palsy
who presented with chronic left arm pain. Examination revealed 12 active joints, predominantly in the left hand. Radiographs showed characteristic changes of an advanced secondary osteoarthritic process in the left hand and only minimal changes on the right. Bone scan confirmed unilateral activity. Subsequent investigations diagnosed hemochromatosis. Unilateral arthropathy of hemochromatosis on a neurogenic basis has not been previously reported.

A list-learning paradigm was used to study learning and memory of verbal and figurative material in children with right versus left-sided hemiplegic
cerebral palsy
. Thirty-one children with right (n = 18), or left (n = 13) congenital
hemiplegia
were compared with normal controls (n = 19). All children had normal intelligence (IQ > 80), and were attending standard schools. The inclusion criteria for the two hemiplegic groups were; no epilepsy, no hearing or visual impairments, and a mild to moderate hemiparesis. The aim of this study was to explore material-specific (words and drawings) differences in the acquisition, recall and serial position effects in children with an early unilateral brain lesion. The left-hemisphere impaired (i.e. right
hemiplegia
) group showed impaired acquisition for drawings, as compared with the normal controls. There was also a material-specific difference in the serial position effect for all three groups. Learning of words followed the primacy principle, whereas the learning of drawings followed the recency principle. There were no group-differences in delayed-recall (i.e. long-term memory) for either words or drawings. The results are discussed in terms of acquisition and retention of verbal and figurative materials in relation to lesion side and size.

Although weakness has been identified in
cerebral palsy
(CP) in isolated muscle groups, the magnitude of weakness in multiple muscles and the patterns of weakness across joints have not been documented. The maximum voluntary contraction of eight muscle groups in the lower extremities of 15 children with spastic diplegia, 15 with spastic
hemiplegia
, and 16 age-matched peers was determined using a hand-held dynamometer. Children with spastic diplegia were shown to be weaker than age-matched peers in all muscles tested, as were the children with
hemiplegia
on the involved side, with strength differences also noted on the uninvolved side. Weakness was more pronounced distally in the groups with CP, and the hip flexors and ankle plantarflexors in spastic CP tended to be relatively stronger than their antagonists as compared with the strength ratios of the comparison group. In conclusion, children with spastic CP demonstrate quantifiable lower-extremity weakness and muscle imbalance across joints.
