[Correlation between kyphosis and flexibility of kyphoscoliosis curves]

Patients with idiopathic scoliosis often have hypokyphosis in their spines, but some patients may exhibit an increase in kyphosis instead. The aim of this study was to define the effect of the kyphosis on the flexibility of scoliotic curves. A total of 100 cases of idiopathic scoliosis were studied with standing posteroanterior and lateral radiographies of the entire spine. Based on the degree of kyphosis, cases were classified into two groups and compared statistically. Group 1 included 61 cases with less than 50 degrees of kyphosis, and group 2 included 39 cases with equal or more than 50 degrees of kyphosis. The average of scoliosis in group 1 was 57.5 degrees compared with 51.3 degrees in group 2, and the averages of the flexibility index were 57.1 vs. 52.7, respectively. The two groups were also compared according to the standing and supine bending scoliosis, flexibility index, and the correlation between kyphosis and flexibility index. There was neither a significant correlation between the kyphosis and scoliosis curves [P>0.05; r<0.5] nor in the flexibility of scoliosis curves between the two groups [P=0.23]. In our study, the presence of kyphosis seems to have no impact on scoliosis curves in patients with idiopathic scoliosis

Osteoblastoma of the spine

To identify the factors that are associated with the development of scoliosis and its manifestations. Summary of the background data: Painful scoliosis is a well-recognized presentation of osteoblastoma but as a result of small number of previous reports, the outcome and habits of tumor in spine is not well-known. Ten factors were assessed including; age, sex, duration of symptoms, site of the lesion, site of lesion in individual, Cobs angle at presentation, chief complaint at presentation, neurological involvement, type of treatment, recurrence of tumor. Result: Fifty% of patients had scoliosis. All of the lesions typically were present on the concave side of the curve. In the thoracic and lumber spine 80% had scoliosis, but no scoliosis was seen on cervical and sacral regions. All the patients were under 30 years. The mean time to diagnose at our center was 18.4 months. All of the patients with cervical involvement [2 patients] had deformity [Cock Robin] and restriction in range of motion. The lesion was in posterior elements in all of the cases and localized in only one side of the spine. Chief complaint was pain in 67%, deformity in 16% and both [pain and deformity] in 17%. Radiological exam was diagnostic in 58% of the cases. Conclusions: Findings support the concept that scoliosis is secondary to asymmetric muscle spasm. The most common complaint is pain and then deformity. In the cervical spins deformity and restriction of motion are chief complaints. In children, spastic pain was more obvious than deformity. Treatment is curettage as wide as possible. There was no recurrence
