BackgroundThis study evaluates the outcome and complications of decompressive cervical Laminectomy and lateral mass screw fixation in 110 cases treated for variable cervical spine pathologies that included; degenerative disease, trauma, neoplasms, metabolic-inflammatory disorders and congenital anomalies.MethodsA retrospective review of total 785 lateral mass screws were placed in patients ages 16-68 years (40 females and 70 males). All cases were performed with a polyaxial screw-rod construct and screws were placed by using Anderson-Sekhon trajectory. Most patients had 12-14-mm length and 3.5 mm diameter screws placed for subaxial and 28-30 for C1 lateral mass. Screw location was assessed by post operative plain x-ray and computed tomography can (CT), besides that; the facet joint, nerve root foramen and foramen transversarium violation were also appraised.ResultsNo patients experienced neural or vascular injury as a result of screw position. Only one patient needed screw repositioning. Six patients experienced superficial wound infection. Fifteen patients had pain around the shoulder of C5 distribution that subsided over the time. No patients developed screw pullouts or symptomatic adjacent segment disease within the period of follow up.Conclusiondecompressive cervical spine laminectomy and Lateral mass screw stabilization is a technique that can be used for a variety of cervical spine pathologies with safety and efficiency.

Background:Cervical spondylotic myelopathy increases with age, but not all cases are symptomatic. It is usually diagnosed clinically and radiologically (X-ray and magnetic resonance imaging). Surgical treatment is indicated in severe symptomatic cases, while treatment controversy exists in the presence of less severe cases. Anterior and posterior approaches are generally used for decompression with no significant differences in the results of both.Methods:A total of 287 patients of cervical spondylotic myelopathy were treated at our hospital between January 2004 and December 2015. Only 140 patients were eligible for our study. They had at least 5 years of follow-up using full clinical scores and radiological evaluation. They were divided into two groups: group I with 73 patients (aged 23–79 years) underwent posterior decompression, lateral mass instrumentation, and fusion, while group II with 67 patients (aged 33–70 years) underwent anterior decompression, instrumentation, and fusion. Neck Disability Index, local score, and X-ray were used in the evaluation of the patients.Results:Preoperative mean ± standard deviation of Neck Disability Index of both the groups was 32.06 ± 6.33 and 29.88 ± 5.48, which improved in the last visit (>5 years) to 5.81 ± 7.39 and 2.94 ± 5.48 for groups I and II, respectively (p value <0.05). The local score of groups I and II was (P = 1, F = 21, G = 31, E = 19) and (P = 1, F = 12, G = 36, E = 18), which on discharge day improved to (P = 1, F = 4, G = 12, E = 55) and (P = 0, F = 3, G = 6, E = 58) at last follow-up, respectively. Fusion rate was nearly equal for both the groups during all the follow-up intervals and it was 91.1% and 91.7% in the last follow-up.Conclusion:There were no significant differences in the clinical and radiological results between the anterior and posterior approaches used in the surgical treatment of spondylotic cervical myelopathy. However, statistically significant results of Neck Disability Index of anterior approach were not clinically important and may be due to changes in the size and shape of the neck in group II.

The present study has used CT analysis to analyze spinal and rib cage modifications in the Porcine Scoliosis Model. Placement of a unilateral ligamentous spinal tether combined with concave rib cage ligament tethering during the rapid growth stage of the Yorkshire pig results in significant apical vertebral and intervertebral wedging and rotational and rib cage modifications. The porcine model is a reliable and duplicable model for scoliosis, which bears significant similarities to AIS.

PurposeThe purpose of this study is to report our short-term functional outcome for 14 children with arthrogryposis multiplex congenita (AMC) who underwent multiple surgical procedures at an early age.MethodsDuring the period 2002–2010, 14 children (11 males and three females) with AMC underwent multiple surgical procedures to treat deformities of the lower and upper limbs. About 81 procedures were performed, at a rate of 5.9 procedures per child. The mean age at the last follow-up was 5.9 years. The average follow-up period was 3.6 years (range, 1.5–6 years). The functional outcome assessment included walking ability and the activities of daily living for the upper limb function.ResultsAt the last follow-up visit, six (43%) children (four males, two females) with a mean age of 8.3 years (range, 4–15) were independent walkers. Three children (males) with a mean age of 3.5 years (range, 2.5–5) were able to walk, but with support. One child (male), 3 years old, was a household ambulator. Three children (two males, one female) with a mean age of 4.2 years (range, 2.5–6) were nonfunctional ambulators. The last child (male) was nonambulatory at the age of 5 years. Activities of daily living were severely affected in the nonambulatory child. One child in the nonfunctional ambulators group had limitations in the activities of daily living; however, upper limb function was not affected in the remaining 12 children.ConclusionWe believe that aggressive surgical treatment using multiple operations at an early age can improve the short-term functional and clinical outcomes of children with AMC.
