The effectiveness of allograft bone for posterior spinal fusion in neuromuscular scoliosis is controversial. Thirty patients with cerebral palsy, treated with posterior spinal fusion, were divided into two groups. Group 1 consisted of 18 patients treated by posterior spinal fusion using autogenous bone graft. Group 2 consisted of 12 patients treated by posterior spinal fusion using freeze-dried allograft bone. The average preoperative curve of 70 degrees in Group 1 was corrected to 35 degrees (50% correction). At 3.2 years average follow-up, the curves averaged 51 degrees (46% loss of correction). The average preoperative curve of 80 degrees in Group 2 was corrected to 39 degrees (51% correction). At 3.5 years average follow-up, the curves averaged 54 degrees (38% loss of correction). Anesthesia time decreased from 344 to 281 minutes (p less than 0.05), and intraoperative blood loss decreased from 2730 to 1740 ml (p less than 0.025) when allograft bone was used as a substitute for autograft bone. Freeze-dried allograft bone is a readily available, safe, and effective substitute for autogenous bone graft in patients with cerebral palsy undergoing posterior spinal fusion.

The handedness of 254 girls with idiopathic scoliosis, minimum age eight years at diagnosis, attending Our Lady's Hospital was related to their scoliosis convexity. Curve patterns were assigned to right or left on the basis of the convexity of the low thoracic component only, regardless of primary curve. The curve pattern matched handedness in 82%. Of 228 right-handed children, 197 had a right convex curve pattern; of 26 left-handed children, 12 had a left convex pattern. The correlation between scoliosis configuration and handedness was statistically significant. This is in contrast to the findings of previous studies, which have considered convexity only, without reference to the configuration of the whole spine. The implication of this finding is that scoliosis is associated with cortical functions.

Lowe oculocerebrorenal syndrome (OCRS), as previously described in the literature, consists of a well-defined constellation of clinical findings involving the eyes, cerebrum, and kidneys. However, the only musculoskeletal abnormalities reported in patients with OCRS have been joint hypermobility, recurrent fractures, rickets, tenosynovitis, and joint effusions. No other specific orthopedic problems have been described. This study presents new clinical findings of scoliosis, kyphosis, platyspondyly, dislocated and/or subluxed hips, and cervical spine abnormalities in six patients with OCRS treated at Carrie Tingley Hospital (Albuquerque, NM, U.S.A.). This study further supports an X-linked recessive mode of inheritance and adds clinical support to the published work that suggests that Lowe syndrome may be due to biochemical abnormalities in glycosaminoglycan metabolism.

Thirty-two adolescent girls braced for late onset idiopathic scoliosis at Children's Hospital, Boston were compared with thirty-two untreated girls from Our Lady's Hospital for Sick Children, Dublin, Ireland paired on the basis of curve size and site and age at diagnosis. All were Risser 0 at diagnosis. Study period for the braced group was from brace initiation to part-time brace wearing and, for the controls, from diagnosis to last review. There was no statistically significant difference between the groups on any parameter of curve progression. This study raises questions about the efficacy of spinal orthoses in modifying the natural history of late-onset idiopathic scoliosis and removes the ethical problems inherent in a prospective trial in which the only treatment permitted to the control group is surgery.

The school scoliosis screening programme at Our Lady's Hospital for Sick Children, Dublin, has provided material for an ongoing prospective natural history study of adolescent idiopathic scoliosis. An examination of the clinical course in 339 girls showed that observation of progression of at least 10 degrees, which occurred in 46 girls (13.6%), depended on the timing of diagnosis and related primarily to the child's position on her growth rate curve and her pubertal status, and much less to skeletal maturity as interpreted by iliac crest ossification or bone age. This has implications for the understanding of results in conservative management, screening programmes and natural history.

Autosomal dominant brachyolmia (Type 3, OMIM #113500) belongs to a group of skeletal dysplasias caused by mutations in the transient receptor potential cation channel, subfamily V, member 4 (TRPV4) gene, encoding a Ca++-permeable, non-selective cation channel. The disorder is characterized by disproportionate short stature with short trunk, scoliosis and platyspondyly. The phenotypic variability and long-term natural course remain inadequately characterized. The purpose of this study was to describe a large Swedish family with brachyolmia type 3 due to a heterozygous TRPV4 mutation c.1847G>A (p.R616Q) in 11 individuals. The mutation has previously been detected in another family with autosomal dominant brachyolmia [Rock et al., 2008]. Review of hospital records and patient assessments indicated that clinical symptoms of brachyolmia became evident by school age with chronic pain in the spine and hips; radiographic changes were evident earlier. Growth was not affected during early childhood but deteriorated with age in some patients due to increasing spinal involvement. Affected individuals had a wide range of subjective symptoms with chronic pain in the extremities and the spine, and paresthesias. Our findings indicate that autosomal dominant brachyolmia may be associated with significant long-term morbidity, as seen in this family.

Lung disease due to nontuberculous mycobacteria (NTM) occurs with disproportionate frequency in postmenopausal women with a unique phenotype and without clinically apparent predisposing factors. Dubbed 'Lady Windermere syndrome', the phenotype includes low body mass index (BMI), tall stature and higher than normal prevalence of scoliosis, pectus excavatum and mitral valve prolapse. Although the pathomechanism for susceptibility to NTM lung disease in these patients remains uncertain, it is likely to be multi-factorial. A role for the immunomodulatory consequences of oestrogen deficiency and altered adipokine production has been postulated. Altered levels of adipokines and dehydroepiandrosterone have been demonstrated in patients with NTM lung disease. Case reports of NTM lung disease in patients with hypopituitarism support the possibility that altered endocrine function influences disease susceptibility. This paper catalogues the evidence for immunomodulatory consequences of predicted endocrine changes in Lady Windermere syndrome, with emphasis on the immune response to NTM. Collectively, the data warrant further exploration of an endocrine link to disease susceptibility in Lady Windermere syndrome.
