OBJECTIVES This study sought to measure the head accelerations induced from upper extremity to head and head to head impact during the game of football and relate this to the risk of mild traumatic brain injury using the Head Impact Power (HIP) index. Furthermore, measurement of upper neck forces and torques will indicate the potential for serious neck injury. More stringent rules or punitive s...

PURPOSE To evaluate penetrating neck trauma for (a) sensitivity of the clinical examination as an indicator of clinically significant vascular injury, and (b) cost-effectiveness of performing screening diagnostic angiography. METHODS The medical records of all patients with penetrating neck trauma presenting at our institution over 4 years were retrospectively reviewed. Injuries were classifi...

BACKGROUND Penetrating trauma of the neck and face is a frequent presentation to acute emergency, trauma and critical care units. There remains a steady incidence of both gunshot penetrating injury to the neck and face as well as non-missile penetrating injury-largely, but not solely, knife-related. Optimal imaging assessment of such injuries therefore remains an on-going requirement of the gen...

Nonspecific (simple) neck pain is the commonest cause of neck symptoms and results from postural and mechanical causes. It includes pain following whiplash injury provided there is no bony injury or objective neurological deficit. The anatomy of the cervical spine is described, with the degenerative changes that are seen in patients with nonspecific neck pain, but also occur with ageing. The po...

Radiotherapy is a key component in the treatment of many head and neck cancers, and its potential to cause long-term adverse effects has become increasingly recognized. In this review, we describe the short-term and long-term sequelae of radiation-associated changes in and injury to the temporal bone and its related structures. The pathophysiology of radiation-induced injury and its clinical en...

The diagnosis of an intra-articular osteoid osteoma can be a challenging and lengthy process, with reports of delayed diagnosis of greater than 2 years. In the young, athletic patient with an atraumatic onset of groin pain, an overuse injury or muscle strain is the most likely etiology. However, an overuse injury of femoral neck stress fracture must be identified because of the potentially disa...

A review of the literature was conducted to find publications relating to neck collars / rolls and prevention of sports injury, particularly burners and other cervical spine injuries, as well as in preventing excessive motion of the cervical spine. MEDLINE (1970-2005), Cinahl (1982-2005), Alt Health Watch (1990-2005), AMED (1995-2005), and the Index to Chiropractic Literature (1985-2005) databa...

The cause of hip and groin pain can be difficult to diagnose because the symptoms are often nonspecific and can be attributed to a wide range of possible conditions. Stress fracture of the femoral neck must be kept in mind when evaluating hip and groin pain in active patients. The consequences of missing such a diagnosis are potentially devastating because of the problematic nature of these inj...

The influence of different seat properties on the head-neck motion during a low-velocity rear-end impact was tested using a Hybrid III-dummy fitted with a modified neck (RID-neck). The results show that by modifying the properties of the seat-back and head-restraint it is possible to influence the head-neck kinematics to a great extent. It was possible to virtually eliminate the neck extension ...
