ABSTRACT

STUDY DESIGN: Retrospective consecutive clinical review of 98 patients. OBJECTIVE: To create a preliminary approach to a clinically important classification of scoliosis in adult patients. SUMMARY OF BACKGROUND DATA: There is currently no accepted classification of scoliosis in adults. High prevalence rates of scoliosis in the elderly and recent studies of health impact support the need for a clinically relevant classification. METHODS: A total of 98 adult patients with scoliosis with a 2-year minimum treatment/follow-up were included. Patients were classified into one of 3 types of deformity based on the degree of lordosis (L1-S1) and frontal plane endplate obliquity of L3 on standing radiographs: type I = lordosis > 55 degrees, L3 obliquity < 15 degrees; type II = lordosis 35 degrees-55 degrees, L3 obliquity 15 degrees-25 degrees; and type III = lordosis < 35 degrees, L3 obliquity > 25 degrees. RESULTS: Curve patterns included thoracic, thoracolumbar, lumbar, thoracic, and lumbar (mean Cobb angle 30 degrees, standard deviation 19 degrees). Cobb angle revealed no correlation to visual analog pain score (VAS) or general health (36-Item Short-Form Health Survey). Significant correlation between endplate obliquity L3, L1-S1 lordosis and VAS was noted (P < 0.05). Mean pain scores of classified patients were: type I, VAS = 27.7; type II, VAS = 43.3; and type III, VAS = 47.1 (type I vs. III, P < 0.05). Surgical rates (failed minimum 3-month conservative care, including bracing, physical therapy, and pharmacological treatment) by group were: type I, 0%; type II, 9%; and type III, 22.7% (P = 0.002). CONCLUSIONS: A simple classification of adult scoliosis was developed based on frontal and sagittal plane standing radiographs. With increasing type (from I to III), self-reported pain and disability increased. This result was reflected in the treatment approach as well, with surgical rates increasing from types I to III. Further refinement is important to develop an all inclusive and sufficiently descriptive system.

ABSTRACT

STUDY DESIGN: This is a prospective radiographic and force plate analysis involving adult volunteer and patients with scoliosis. OBJECTIVE: To assess accurately the center of pressure in standing volunteers and patients with scoliosis, and correlate these finding with radiographic data. SUMMARY OF BACKGROUND DATA: A simple and commonly applied parameter of global balance is the plumbline offset. This radiographic measurement refers to the center of C2 (or C7) drawn vertically downward. Although this measurement is simple, it may not accurately reflect the balance of the spine. METHODS: This study included adult volunteers (n = 41) and patients with scoliosis (n = 45). Full-length, freestanding spine radiographs were obtained with subjects on a force plate. Simultaneous assessment of the radiologic spinal posture and the floor projection of the center of pressure (gravity line) was possible. The latter was projected on the full spine images and correlated to common radiographic parameters. RESULTS: The position of the gravity line differed significantly from the plumbline in frontal and sagittal planes (P < 0.001). This difference was maintained in both study populations. The mean frontal plane alignment of the gravity line was consistently to the right of the plumbline. The mean sagittal plane alignment of the gravity in relation to the plumbline revealed an offset anteriorly. CONCLUSIONS: The data analysis of offsets between the gravity line and radiographic parameters revealed a frontal plane mean displacement of the gravity line to the right. In the sagittal plane, a highly significant lack of correlation between the gravity line and plumbline was noted. The plumbline represents a common and convenient visual display of apparent sagittal plane imbalance, but its value as a marker of true postural balance must be questioned.

ABSTRACT

STUDY DESIGN: A prospective self-assessment analysis and evaluation of nutritional and radiographic parameters in a consecutive series of healthy adult volunteers older than 60 years. OBJECTIVES: To ascertain the prevalence of adult scoliosis, assess radiographic parameters, and determine if there is a correlation with functional self-assessment in an aged volunteer population. SUMMARY OF BACKGROUND DATA: There exists little data studying the prevalence of scoliosis in a volunteer aged population, and correlation between deformity and self-assessment parameters. METHODS: There were 75 subjects in the study. Inclusion criteria were: age > or =60 years, no known history of scoliosis, and no prior spine surgery. Each subject answered a RAND 36-Item Health Survey questionnaire, a full-length anteroposterior standing radiographic assessment of the spine was obtained, and nutritional parameters were analyzed from blood samples. For each subject, radiographic, laboratory, and clinical data were evaluated. The study population was divided into 3 groups based on frontal plane Cobb angulation of the spine. Comparison of the RAND 36-Item Health Surveys data among groups of the volunteer population and with United States population benchmark data (age 65-74 years) was undertaken using an unpaired t test. Any correlation between radiographic, laboratory, and self-assessment data were also investigated. RESULTS: The mean age of the patients in this study was 70.5 years (range 60-90). Mean Cobb angle was 17 degrees in the frontal plane. In the study group, 68% of subjects met the definition of scoliosis (Cobb angle >10 degrees). No significant correlation was noted among radiographic parameters and visual analog scale scores, albumin, lymphocytes, or transferrin levels in the study group as a whole. Prevalence of scoliosis was not significantly different between males and females (P > 0.03). The scoliosis prevalence rate of 68% found in this study reveals a rate significantly higher than reported in other studies. These findings most likely reflect the targeted selection of an elderly group. Although many patients with adult scoliosis have pain and dysfunction, there appears to be a large group (such as the volunteers in this study) that has no marked physical or social impairment. CONCLUSIONS: Previous reports note a prevalence of adult scoliosis up to 32%. In this study, results indicate a scoliosis rate of 68% in a healthy adult population, with an average age of 70.5 years. This study found no significant correlations between adult scoliosis and visual analog scale scores or nutritional status in healthy, elderly volunteers.

ABSTRACT

STUDY DESIGN: A prospective self-assessment analysis of a consecutive series of adult patients diagnosed with adult scoliosis of adolescent onset or de novo degenerative scoliosis. PURPOSE: To analyze the impact that scoliosis has on patient health perceptions. SUMMARY OF BACKGROUND DATA: There exists little data studying the effect scoliosis has on an adult's self-perception of health. METHODS: Inclusion criteria were: age > or =18 years, Cobb angle greater than 10 degrees, degenerative or idiopathic deformity, no prior surgery (spine), and complete records. Each patient completed the standard Short Form-36 (SF-36) questionnaire. For each patient, radiographic and clinical data were evaluated. After all data were collected, the mean, standard deviation (SD), and true N values of the Cobb angle were calculated. This study population was then divided into two groups: patients with a Cobb angle greater than 10 degrees and patients with a Cobb angle greater than 20 degrees. Comparison of the SF-36 data for adult scoliosis patients with the United States general population, the United States general population ages 55-64, and patients with hypertension and low back pain was undertaken. RESULTS: The mean age for the patients in this study was 63 years of age; 22 patients were diagnosed as having adult scoliosis of adolescent onset and 27 patients had de novo degenerative scoliosis. The Cobb angle in this study group was found to be greater than 20 degrees in 41 patients; of these patients, 19 patients had a diagnosis of adult scoliosis of adolescent onset and 22 patients had a diagnosis of de novo degenerative scoliosis. Taken as a whole, the patients in this study averaged scores much lower than the norms for both the general U.S. population in all 8 categories and the U.S. population for ages 55 to 64 in 7 out of 8 categories of the SF-36 questionnaire. Additionally, patients with scoliosis also showed lower scores compared to that of the norms found of patients with comorbid conditions: back pain/sciatica with hypertension in seven of the eight categories: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health. Of the radiographic parameters analyzed, loss of lumbar lordosis revealed a significant correlation with social function: P = 0.018; role emotional: P = 0.038; and overall general health: P = 0.05. The other radiographic parameters did not reveal statistically significant correlation to the calculated SF-36 scores. CONCLUSION: Our data clearly demonstrate the impact that adult scoliosis has on a patient's perception of health. The severity of this impact is strikingly apparent in the SF-36 scores when compared to benchmark data on patients with comorbid conditions such as back pain and hypertension. It is our conclusion that adult scoliosis is becoming a medical condition of significant impact, affecting the fastest growing section of our society to a previously unrecognized degree.

ABSTRACT

STUDY DESIGN: Prospective analysis of a consecutive series of adult patients with adolescent idiopathic scoliosis of the adult and de novo degenerative scoliosis. OBJECTIVES: To clinically and radiographically study two populations of adult patients with either adolescent idiopathic scoliosis of the adult or de novo degenerative scoliosis in a quantitative manner to identify reliable radiographic parameters that correlate with clinical symptoms. SUMMARY AND BACKGROUND: Although there are many causes of spinal deformity in the adult, there are two main categories of adult scoliosis: adolescent idiopathic scoliosis of the adult and de novo degenerative scoliosis. Unlike pediatric scoliosis, in adults there are no established radiographic parameters or classification systems that reliably provide a clinical correlation or offer a useful language for communication among specialists. This study gathered complete clinical and radiographic information on 95 patients with adult scoliosis and established several radiographic parameters that correlated with clinical symptoms. METHODS: Each of the 95 patients completed a clinical questionnaire that included a self-reported visual analog scale and underwent full-length standing anteroposterior and lateral radiography. Radiographic analysis was performed by use of digital analysis and included measurement of the Cobb angle, the number of vertebrae in each curve, plumbline offset from T1 to the midsacral line, the upper endplate obliquities of L3 and L4, and maximal lateral olisthy between two adjacent lumbar vertebrae. Sagittal plane measurements included lumbar lordosis, thoracolumbar kyphosis, and the Sagittal Pelvic Tilt Index. Statistical analysis of both radiographic and clinical parameters of pain was performed to determine any significant correlations between the two. RESULTS: This study showed that lateral vertebral olisthy, L3 and L4 endplate obliquity angles, lumbar lordosis, and thoracolumbar kyphosis were significantly correlated with pain. CONCLUSION: This quantitative analysis identified several clinically relevant radiographic parameters in adult scoliosis patients. Additionally, excellent predictive formulas for self-reported pain levels were obtained.
