Trevor's disease, also known as dysplasia epiphysealis hemimelica, is an uncommon skeletal developmental disorder representing an osteochondroma occurring in one or more epiphyses. We present 2 cases of dysplasia epiphysealis hemimelica in an 8-year-old female and a 12-year-old male who suffered from a hard swelling of the ankle joint. The female patient was treated by surgical excision and the male patient conservatively.

Background: Restoration of spinopelvic balance during spinal surgery is very important to ensure a good outcome. Many studies have been conducted to define the normal ranges, examining the correlation between these individual parameters and their relation with spinal parameters of thoracic kyphosis and lumbar lordosis. The ranges, specific to individual ethnicities, is very essential to restore the sagittal balance in patients suffering from spinal degenerative conditions. Hence this study aims to define the average ranges of relevant spinopelvic parameters in the adult population of Indian origin. Methods: A observational cross sectional study was conducted in 130 healthy volunteers in Mumbai without having any spine, hip or pelvis pathology. Spinopelvic parameters like Pelvic Incidence(PI), Sacral Slope(SS) and Pelvic Tilt(PT) were studied and compared between various other similar studies with patients of different ethnicities. The correlation of those parameters with each other was also evaluated. Results: The mean value of PI was 51.50(±6.85 ), that of SS was 39.17 (±6.26 ) and for PT it was 12.32 (±5.41 ). These values were statistically significant between both sexes for PI and PT. The strongest positive correlation among the parameters was between pelvic incidence and sacral slope, with a r-value of 0.668. Comparison of our study with similar studies within the country (Chennai, Delhi and Surat) showed statistically significant differences in PT and SS of all three studies while PI was not significant when compared with the Surat study. Conclusion: There appears to be considerable variation of the values of the spinopelvic parameters as determined by various studies due to ethnic variations. Further studies should be done with larger samples and directed towards early detection of individuals at risk of developing degenerative spinal disorders with sagittal imbalance, so that interventions can be made at an earlier stage.

Study DesignRetrospective case series.PurposeTo describe a novel single incision that combines anterior and posterior approaches for decompression and instrumented fusion to treat tuberculosis of the thoracic spine and study the neurological and radiological outcomes.Overview of LiteratureTuberculosis of the spine remains a major health issue in many developing countries. The options for treating tuberculosis of the thoracic spine include the anterior, posterior, and combined approaches, each with its advantages and disadvantages.MethodsTotally, 143 patients with tuberculosis of the thoracic spine were surgically treated using the “Versatile approach”. Posterior fixation was performed using sublaminar wires and a Hartshill rectangle in all patients. Anterior reconstruction was accomplished using bone graft harvested from autologous rib, iliac crest, or fibula.ResultsThe study included 45 males and 98 females, with a mean age of 33.18±18.65 years (range, 3–82 years) and a mean follow-up of 60.23±24.56 months (range, 18–156 months). Kyphosis improved from a mean value of 24.02 preoperatively to 10.25 postoperatively. A preoperative neurological deficit was observed in 131 patients, with 130 patients regaining ambulatory power. No patient had deterioration of neurological status following surgery. Fusion was achieved in all cases. The visual analogscale score improved from an average score of 7.02 preoperatively to 1.51 at final follow-up. Eight patients had superficial macerations, which healed spontaneously. One patient had buckling of the anterior graft, and one patient had implant breakage following road traffic accident.ConclusionsThe “Versatile approach” is an effective, single-stage, single-incision method that combines anterior and posterior approaches for the surgically treating tuberculosis of the thoracic spine. It offers the advantage of direct visualization for decompression and reconstruction of the anterior and posterior vertebral columns, thus providing an excellent, long-lasting clinical outcome.
