摘要:

Two-hundred thirty-eight Southern Chinese girls, aged 10 to 14 years, treated previously for adolescent idiopathic scoliosis were studied longitudinally from the commencement of their treatment until maturity. Their standing, sitting, and suprasternal heights were measured at each follow-up visit, and their lower limb, head-neck, and spinal lengths were calculated. The results in 113 girls treated by posterior spinal fusion and Harrington instrumentation were compared with those of 125 girls who were treated with a brace. At maturity, the mean standing height of girls who underwent spinal fusion was not significantly different from that of patients treated with a brace. The fusion group had significantly shorter spinal lengths (p= 0.001), but significantly greater leg lengths (p= 0.001) compared to those of the brace group. Their arm lengths were similar, however. The girls who underwent spinal fusion had progressively increasing leg/arm ratios postoperatively from bone age 14–15 years onward compared to those treated with a brace, which indicated disproportionately longer legs in the girls who had spinal fusion. These findings suggest that spinal fusion performed on the girls with adolescent idiopathic scoliosis did retard the longitudinal growth of the spine. The standing height was unaffected, however, as the loss in spinal length was compensated by an increase in leg length.

摘要:

Orthopedic surgeons commonly use the Risser sign to estimate skeletal maturity; however, the data presented in the orthopedic literature supporting the accuracy of the Risser sign in estimating skeletal maturity do not stand up to critical statistical analysis. The Risser sign is less accurate than chronologic age as a predictor of skeletal age and should not be used as a substitute for a hand and wrist radiograph in most cases. The Risser sign is also no better a predictor of scoliosis progression than is chronologic age.

摘要:

Scoliosis surgery has been associated with pancreatitis and acalculous cholecystitis, and also has been implicated as a risk factor for cholelithiasis. A prospective study of 36 children and adolescents undergoing scoliosis surgery was performed using ultrasound to determine the incidence of cholelithiasis following spine surgery. The patients underwent abdominal ultrasound exams preoperatively, immediately postoperatively, and then at intervals following surgery with 2–5-year follow-up. Four of 36 patients (11.1%) (one male, three female) developed gallstones, although all had been free of gallstones after surgery. The gallstones appeared between 2 + 5 and 5 years after surgery. Those with gallstones were not different from those without with respect to 14 factors. It is concluded that scoliosis surgery is not a risk factor for gallstones, because of the delay in onset of cholelithiasis after surgery. Furthermore, the prevalence of gallstones in this study sample is not greater than that reported in historical control studies of European young adults.

摘要:

We attempted to characterize the signs and symptoms of patients presenting with scoliosis as a manifestation of occult syringomyelia, and to determine the effect of syrinx decompression on the deformity and neurologic deficits. This study represented 21 patients treated from 1981 through 1991 at the authors' institution. All patients with occult syringomyelia and no other central nervous system lesions underwent decompression of the syrinx, with improvement in neurologic signs and symptoms. Three of the four with scoliosis that were not treated by arthrodesis showed improvement of their deformity at an average follow-up of 35 months. Three of five patients with myelodysplasia, occult syringomyelia, and scoliosis not previously treated with spinal arthrodesis showed stabilization or improvement of their deformity at an average follow-up of 21 months. We conclude that syringomyelia is associated with a high incidence of developmental scoliosis, and that decompression of the syrinx leads to improvement in, or stabilization of, the majority of scoliotic curves, or postpones the need for fusion.

摘要:

Radiographic spinal evaluations were done on 305 patients with myelodysplasia. Asymptomatic spondylolisthesis, which averaged 37.1% translation, was seen in 5.9% of the patients. The prevalence of spondylolisthesis increased to 15.6% of patients with L5-S1 motor levels. Patients with myelodysplasia do develop spondylolisthesis. Increased lumbar lordosis and concomitant diminished thoracic kyphosis were commonly seen in the patients with spondylolisthesis.

摘要:

In the last decade, experience with intraoperative somatosensory evoked potential (SSEP) monitoring has been reported in a wide variety of surgical procedures, mostly in adult patients. Reported experience has been limited in children. Children can present a number of unique problems that must be recognized and for which techniques must be adapted. This article presents the intraoperative SSEP experience at the Children's Hospital in Boston from 1989 to 1991. The technical difficulties we have encountered commonly in young children are discussed, along with suggestions in technical adjustments. As in adults, we have found intraoperative monitoring helpful in assessing physiological integrity of the spinal cord in children.

摘要:

In a series of 43 patients diagnosed with congenital anterolateral bowing of the tibia or congenital pseudarthrosis of the tibia treated between 1980 and 1992, the deformities corrected themselves spontaneously in five patients who had no other congenital abnormalities or evidence of neurofibromatosis. At an average follow-up of 58 months (average age at follow-up 80 months), the only residual deformity seen was a limb-length discrepancy in patients with unilateral involvement. In patients with subperiosteal callus formation on the posteromedial concavity of this deformity and an uninvolved fibula, no treatment appears necessary, as this deformity will spontaneously resolve.

摘要:

Dorsal defect of the patella is a benign subchondral lesion of unknown etiology, located in the superolateral region of the patella. The lesion presents with a characteristic radiographic appearance consisting of a rounded focus of radiolucency surrounded by a sclerotic margin. Although often an incidental finding on knee radiographs, it occasionally may be symptomatic. It occurs in males and females with equal frequency, is bilateral in up to one third of individuals, and is most frequently found in adolescents. This report describes a series of eight such lesions in five patients.

摘要:

Anteversion and arthritic changes were recorded in 110 well-preserved femora to identify a correlation between knee osteoarthritis and anteversion. Arthritis was recorded as no change (grade 0), osteophytes (grade 1), cysts or erosions (grade 2), and burnishing or eburnation (grade 3). Anteversion was identified by measure of the angle between the axis of the head-neck and the axis of the posterior condyles. There was no relation between anteversion and proximal femoral arthritis but increased arthritis of the distal femur with decreased anteversion (p< 0.04) was identified, establishing a correlation between femoral anteversion and arthritis of the knee.
