STUDY DESIGN: Retrospective case series. OBJECTIVES: To determine the influence of spine and trunk deformity on preoperative idiopathic scoliosis patients' health-related quality of life questionnaire responses. SUMMARY OF BACKGROUND DATA: Management recommendations for patients with idiopathic scoliosis during adolescence are based heavily on spine deformity and to some extent trunk deformity magnitude. However, the manner in which these objective measures influence the patients' perception of their condition is unclear. METHODS: Of 67 consecutive preoperative patients, 61 (91%) had completed the Scoliosis Research Society-22 health-related quality of life questionnaire and had been studied with posterior exposure surface topography. Their average age was 15 years, 6 months (range 10 years, 10 months-20 years, 10 months), and the average maximum Cobb was 63 degrees (range 40-137 degrees). Correlations between spine and trunk deformity measures and Scoliosis Research Society-22 scores were determined by the Pearson correlation coefficient, with P < 0.01 considered significant. RESULTS: For the study group, spine deformity (Cobb) correlated significantly only with Scoliosis Research Society-22 function (r = -0.39, P = 0.0022) domain. Neither coronal nor transverse plane trunk deformity composite scores correlated with any Scoliosis Research Society-22 scores. The Hump Index component of the transverse plane Suzuki Hump Sum composite score was the only trunk measurement to correlate significantly (function r = -0.45, P = 0.003; self image, r = -0.36, P = 0.0040). The strongest correlations occurred when the single thoracic curves, King classifications III and IV, were combined: Cobb versus function r = -0.53, P = 0.0027; Cobb versus self-image r = -0.46, P = 0.0099; and Hump Index versus function r = -0.60, P = 0.0005. There were no significant correlations between either spine deformity or any trunk deformity measure with Scoliosis Research Society-22 responses for either the double or thoracolumbar curve pattern groups. CONCLUSION: Both spine and upper thoracic transverse plane trunk deformity significantly influenced preoperative idiopathic scoliosis patients' perception of function and self-image, but not pain or mental health. However, in spite of a fairly rigorous standard of proof, P < or = 0.01, the significant r values ranged from -0.33 to -0.68, suggesting that there are factors other than spine and trunk deformity influencing the idiopathic scoliosis patients' health-related quality of life questionnaire responses. Future studies are necessary to define these factors.
STUDY DESIGN: A case of necrotizing soft tissue infection in a patient with spinal cord injury with extension of infection into the spinal canal and spinal cord is presented. OBJECTIVE: To review the history, risk factors, pathophysiology, diagnosis, treatment, and morbidity and mortality regarding necrotizing soft tissue infection as they relate to spinal cord injury. SUMMARY OF BACKGROUND DATA: Necrotizing soft tissue infection related to decubitus ulcers is rare. To our knowledge, this is the first report of this disease related to a sacral decubitus ulcer with extension of the necrotizing infection into the spinal canal. METHODS: The clinical, radiographic, and pathologic features associated with necrotizing soft tissue infection are presented. The patient presented with a late-stage necrotizing soft tissue infection requiring extensive de-bridement of necrotic tissue, which the patient underwent on admission. RESULTS: The patent died of refractory septic shock and multiple-organ failure after surgery. CONCLUSION: Necrotizing soft tissue infections from decubitus ulcers are rare and unpredictable, and ultimately have a progressively aggressive course. The case reported herein is the first report of necrotizing soft tissue infection from a decubitus ulcer in a patient with spinal cord injury with extension into the spinal canal and spinal cord.
A number of methods exist for the estimation of abdominal obesity, ranging from waist-to-hip ratio to computed tomography (CT). Although dual-energy X-ray absorptiometry (DXA) was originally used to measure bone density and total body composition, recent improvements in software allow it to determine abdominal fat mass. Sixty-five men and women aged 18-72 yr participated in a series of studies to examine the validity and reliability of the DXA to accurately measure abdominal fat. Total body fat and abdominal regional fat were measured by DXA using a Lunar DPX-IQ. Multislice CT scans were performed between L1 and L4 vertebral bodies (region of interest) using a Picker PQ5000 CT scanner, and volumetric analyses were carried out on a Voxel Q workstation. Both abdominal total tissue mass (P = 0.02) and abdominal fat mass (P < 0.0001) in the L1-L4 region of interest were significantly lower as measured by DXA compared with multislice CT. However, Bland-Altman analysis demonstrated good concordance between DXA and CT for abdominal total tissue mass (i.e., limits of agreement = -1.56-2.54 kg) and fat mass (i.e., limits of agreement = -0.40-1.94 kg). DXA also showed excellent reliability among three different operators to determine total, fat, and lean body mass in the L1-L4 region of interest (intraclass correlations, R = 0.94, 0.97, and 0.89, respectively). In conclusion, the DXA L1-L4 region of interest compared with CT proved to be both reliable and accurate method to determine abdominal obesity.
