=====Trampoline injury===== Trampolines were responsible for over 6,500 pediatric cervical spine injuries in 1998. This represents a five-fold increase in just 10 years. While most have been minor, [[paraplegia]], [[quadriplegia]] and death are all reported. Brown and Lee present 2 cases of trampoline-related [[cervical spine injury]] and review the relevant [[literature]]. Additionally, they examine the efforts made to reduce the incidence of trampoline injuries, and discuss why these have failed. They conclude that safety [[guideline]]s and warnings are inadequate. In addition, they support [[recommendation]]s for a ban on the use of trampolines by children ((Brown PG, Lee M. Trampoline injuries of the cervical spine. Pediatr Neurosurg. 2000 Apr;32(4):170-5. Review. PubMed PMID: 10940766. )). see Severe Trampoline Injuries: Incidence and Risk Factors in Children and Adolescents ((Korhonen L, Salokorpi N, Suo-Palosaari M, Pesälä J, Serlo W, Sinikumpu JJ. Severe Trampoline Injuries: Incidence and Risk Factors in Children and Adolescents. Eur J Pediatr Surg. 2017 Nov 22. doi: 10.1055/s-0037-1608676. [Epub ahead of print] PubMed PMID: 29166677. )). ====Case reports==== A 4-year-old boy who presented with neck pain after falling off a trampoline. His neurological examination did not reveal any focal abnormalities, but radiographs were thought to be consistent with a right, C4-C5, unilateral, jumped facet. Reduction attempts were made with Gardner-Wells tongs and traction. After failure to achieve adequate reduction, evaluations using two-dimensional computed tomography confirmed congenitally absent [[cervical pedicle]]s. He was treated conservatively and experienced resolution of their presenting symptoms. The congenital absence of a cervical pedicle is a rare entity that is frequently misdiagnosed. Diagnoses can be accurately confirmed with two-dimensional computed tomography. [[Conservative treatment]] resulted in successful management of this clinical entity ((Sheehan J, Kaptain G, Sheehan J, Jane J Sr. Congenital absence of a cervical pedicle: report of two cases and review of the literature. Neurosurgery. 2000 Dec;47(6):1439-42. Review. PubMed PMID: 11126916. )).
