Abstract

Objective Conventional cervical pedicle screw insertion necessitates extensive paraspinal muscle dissection and retraction in order to achieve the lateral to medial angulation needed to achieve the optimal screw trajectory. Minimally invasive transmuscular approach can comfortably achieve this angulation without significant injury to the midline structures and its musculo-ligamentous attachments. Methods Minimally invasive cervical pedicle screws were inserted in 4 fresh frozen cadaveric specimens. Pre-procedure and post-procedure CT scans were done to assess the pedicle dimensions, suitability for screw insertion and integrity of the screws. The same technique was applied in a clinical cohort of six cases – 3 cases of traumatic subluxation; one case of traumatic vertebral fracture and 2 cases of infective facet destruction (Koch’s). Results Among the 38 screws in the cadaver specimens, a total of 11 screws (28.9%) had breached the pedicle wall(Lateral wall breach–9; Medial wall breach–2). Of the 9 screws (23.6%) that had a lateral breach into the vertebral canal, 4 (10.5%) each had Grade IIa breach and one (2.6%) had Grade III breach. Among the 22 screws inserted in the clinical cohort of 6 cases, 4 screws (18.1%) had breached the pedicle wall. All the identified breaches were in the lateral wall(Grade IIa – 3; Grade IIb–1; Grade III–nil). Conclusion Minimally invasive subaxial pedicle screw insertion provides robust posterior cervical fixation, either in isolation or as an adjunct to anterior surgery, in cases where a direct posterior decompression is not warranted. It is a safe and effective approach which minimizes injury to the paraspinal structures and midline attachments.

Abstract

ObjectivesThis paper describes the methodology of developing and implementation of a youth focused life skills training and counselling services programme (LSTCP) and assessment of factors associated with life skills of participants pre-training.DesignDevelopment of all aspects of LSTCP (modules, methods and evaluation) was through a consultative process. Experiential learning based facilitation was decided as the approach for training participants. A quasi-experimental design with pre, post and follow-up assessment post-training was finalised. Data collection was done using specifically developed semi-structured self-administered questionnaire.ResultsMultivariable logistic regression with life skills as outcome and various exposure variables was performed. About 2/3rd of participants had high level of life skills (68%). Increased score of extraversion (AOR = 1.57,95% CI = 1.32-1.85), agreeableness (AOR = 1.42,95% CI = 1.16-1.73), conscientiousness (AOR = 1.9,95% CI = 1.55-2.33), physical (AOR = 1.03,95% CI = 1.01-1.04), environmental (AOR = 1.02,95% CI = 1.004-1.03) and social quality of life (AOR = 1.01,95% CI = 1.006-1.02) were associated with high life skills score. Higher score of neuroticism (AOR = 0.66,95% CI = 0.53-0.79) was associated with low life skills score.ConclusionThe results presented provide an opportunity to understand the evolution of factors affecting life skills during the follow-up of this study. This study throws light on development of LSTCP for apparently healthy population in a setting like India and its states.
