Comparative Study
Abnormal anthropometric measurements and growth pattern in male adolescent idiopathic scoliosis.
The progression of adolescent idiopathic scoliosis is closely correlated with longitudinal growth during puberty. A decreased incidence of curve progression has been found in male patients with adolescent idiopathic scoliosis compared with female patients with the condition. This finding implies that there might be a sexual dimorphism in the pubertal growth patterns of adolescent idiopathic scoliosis patients. Abnormal pubertal growth in female adolescent idiopathic scoliosis patients has been well characterized; however, the pubertal growth patterns of male adolescent idiopathic scoliosis patients have not been reported. We conducted a cross-sectional study of anthropometric measurements to compare the growth patterns of male patients with adolescent idiopathic scoliosis with those of healthy boys during puberty and explore the difference in the pubertal growth patterns of female and male patients with adolescent idiopathic scoliosis. ⋯ The results showed abnormal pubertal growth in the male adolescent idiopathic scoliosis patients compared with their age- and gender-matched normal controls. Despite similar longitudinal growth, the male patients with adolescent idiopathic scoliosis exhibited significantly lower body weights and a higher incidence of underweight during the later stage of puberty compared with their normal controls. These abnormalities in the pubertal growth of male patients were different from those observed in female patients with adolescent idiopathic scoliosis. Body weight could be an important parameter for further longitudinal studies on the prognostication of curve progression in adolescent idiopathic scoliosis.

Vertebral body resection to treat spine tumors necessitates reconstruction to maintain spinal stability. The durability of reconstruction may be a challenge in cancer patients as treatment with chemotherapy and/or radiation coupled with poor nutritional status may compromise bone quality. We present a series of patients who underwent implantation of an expandable titanium cage (ETC) for reconstruction after vertebral body resection for primary or metastatic spine tumors. We report the functional outcome, assess the durability of reconstruction, and describe complications associated with this procedure. ⋯ Use of an ETC for spinal reconstruction in patients with spinal tumors is safe, decreases pain associated with pathologic fracture, protects neurologic function, and is durable. We found a very low incidence of cage-related construct failures and no significant problems with subsidence.

Understanding how to classify and quantify three-dimensional (3D) spinal deformities remains an open question in adolescent idiopathic scoliosis. The objective of this study was to perform a 3D manifold characterization of scoliotic spines demonstrating thoracic deformations using a novel geometric and intuitive statistical tool to determine patterns in pathological cases. ⋯ Quantitative evaluation illustrates that the complex space of spine variability can be modeled by a low-dimensional manifold and shows the existence of an additional hyper-kyphotic subgroup from the cohort of 3D spine reconstructions of Lenke Type-1 patients when compared with previous findings on the 3D classification of spinal deformities.

Randomized Controlled Trial
The Canadian Occupational Performance Measure's semi-structured interview: its applicability to lumbar spinal fusion patients. A prospective randomized clinical study.
Although lumbar spinal fusion has been performed for more than 70 years, few studies have examined rehabilitation strategies for spinal fusion patients, and there is only sparse information about the patient's activity level after surgery. The Canadian Occupational Performance Measure (COPM) is a standardized semi-structured interview, developed to identify patients' problems in relation to activities of daily living (ADL). The COPM has neither been examined in a randomised clinical study nor employed in relation to lumbar spinal fusion patients. We aimed to examine whether or not the use of the semi-structured interview COPM during in-hospital rehabilitation could: (1) identify more ADL-related problems of importance to the patients after discharge from the hospital, (2) enhance the patients' ADL performance after discharge from hospital ⋯ Use of the COPM during hospitalization helped in identifying more ADL problems encountered by patients during the first 3 months post-discharge period as COPM served to identify more treatment goals and plans of action. Use of the COPM had no impact on the patients' ADL performance, and the difference is so small that COPM may be of little clinical consequence.
