Cervical spinal stenosis and sports-related cervical cord neurapraxia
Department of Neurological Surgery, University of California, San Francisco, California 94143-0112, USA.Neurosurgical FOCUS (Impact Factor: 2.11). 11/2011; 31(5):E7. DOI: 10.3171/2011.7.FOCUS11173
Cervical cord neurapraxia is a common sports-related injury. It is defined as a transient neurological deficit following trauma localizing to the cervical spinal cord and can be caused by hyperextension, hyperflexion, or axial load mechanisms. Symptoms usually last less than 15 minutes, but can persist up to 48 hours in adults and as long as 5 days in children. While a strong causal relationship exists between cervical spine stenosis and cervical cord neurapraxia in adult patients, this association has not been observed in children. Likewise, while repeated episodes of neurapraxia can be commonplace in adult patients, recurrences have not been reported in the pediatric population. Treatment is usually supportive, but in adults with focal cervical lesions or instability, surgery is an option. Surgery for neurapraxia in children is rarely indicated.

ABSTRACT: Spinal cord injuries are uncommon in sports. Planning and practice for their occurrence, however, remains an essential component of Sideline Medical Team preparedness. Evaluation of cervical nerve injury, cervical cord injury, and cervical disc disease can be complex. Medical management, diagnostic imaging techniques and surgical recommendations in this setting continue to evolve. Most published guidance offers occasionally opposed expert opinion with sport participation after Cervical Cord Neuropraxia in the setting of Cervical Spinal Stenosis appearing particularly polarizing. Such conflicts can present challenges to clinicians in forming management and Return to Play decisions for the health of their athletes.

ABSTRACT: Modern sports activities are associated with a high incidence of spine pain. Generally, the injuries seen are classified to their time of onset or specific injuries related to the vulnerable skeletal locations. Spinal fracture is fortunately very rare for incidences that are associated in contact sports activities. Prevention of spinal injuries and early diagnosis are the first priorities since delayed diagnosis may cause structural instability and early osteoarthritis or abnormal bony maturity. When plain radiographs of a patient with persistent symptoms reveal negative findings, a bone scan with single-photon emission computed tomography, computerised tomography scan or magnetic resonance imaging scan can be performed. Nuclear medicine imaging techniques, encompassing the visualisation and characterisation of biological processes at the molecular and cellular level, are useful techniques in localising the site of spinal injuries which are inconspicuous on the structural conventional imaging techniques.
