Delayed myelopathy after trivial neck injury in a patient with a cervical neurenteric cyst.

BACKGROUND: Neurenteric cysts are rare spinal lesions of congenital origin. They usually present insidiously with a long history of local spinal pain, radiculopathy and myelopathy. We report a 14-year-old male with a high cervical neurenteric cyst who developed a progressive myelopathy after minor neck trauma. Full recovery followed a partial cyst excision and decompressive procedure. SIGNIFICANCE AND CONCLUSION: The possible pathogenic mechanisms for this unusual presentation include hemorrhage into the cyst, sudden mechanical compression from abnormal spinal movement of a chronically distorted and compressed spinal cord, or an increase in the size of the cyst secondary to accumulation of cyst fluid. In this case a small increase in the cyst size may have resulted in increased mechanical distortion and spinal cord dysfunction on a compressive and ischemic basis.

Neck injury sustained during exposure to high-G forces in the F16B.

Neck pain is a frequent complaint among aviators flying high performance fighter (HPF) aircraft. However, very few--if any--cases of subjective symptoms have been confirmed by objective methods and reported in the literature. The present paper relates an incident of documented injury of the cervical spine which occurred during an abrupt and violent maneouver in the F16B. The rear seat occupant, a flight surgeon, who had just handed over controls to the instructor flying from the front seat, was caught unaware. He suffered a ligament injury C5-6 and a sliding of the C6 relative to the C5. It is concluded: 1) The accelerative forces in HPF aircraft can cause serious injury to the cervical spine and its supporting structures in the neck. 2) Aircrew not engaged in the flying task may be at risk if left ignorant of pilots' intentions. 3) Lightweight helmets reduce the medical hazards imposed upon aviators in the high-G environment. 4) Specific exercises aimed at strengthening the neck muscles are encouraged.

Hyoid bone position in children following neck injury.

Previously described radiographic signs of hyoid bone elevation, seen on the lateral radiograph, suggesting tracheal transection (Polansky et al., 1984) are present in uninjured children. These signs are therefore not reliable indicators of tracheal transection in children.

[Case report: foreign body causing a penetrating neck injury].

A 30 year old man is admitted to the emergency section with the complaint of bleeding from the neck after an industrial explosion. A laceration, 5 cm's in length, is seen on 'zone II', near the medial border of the anterior jugular triangle. The patient was hemodynamically stable, but there was active bleeding from the laceration. A round mass is detected with palpation adjacent to the bifurcation of carotis. The wound is explored under anesthesia with endotracheal intubation. Major vessels and other vital structures found to be undamaged. Many authors suggest mandatory exploration for the neck wounds that penetrated the platysma, while others prefer exploration for selected cases on the basis of diagnostic studies. Immediate exploration is indicated in the presence of active bleeding, and diagnostic studies should be reserved for haemodynamically stable patients. Injury of major vessels might be tamponaded by foreign bodies, therefore blind removal of the objects may cause life-threatening hemorrhage. Endotracheal intubation is appropriate in the management of airway, as for convenient surgical approach.

Delayed onset of Lhermitte's sign following head and/or neck injuries. Report of four cases.

The authors report four patients who suffered the delayed onset of Lhermitte's sign following head and/or neck trauma with no significant neurological deficits. The average onset from the time of the injury was 2 1/2 months. In all patients, there was a full range of movement of the cervical spine with no tenderness and no neurological deficits. Myelography was performed in three of the four patients and was normal. The duration of Lhermitte's sign ranged from 4 months to 1 year (mean 8 months). Complete recovery occurred in all cases. The pathogenesis, differential diagnosis, and management of patients with Lhermitte's sign are discussed.

Correlation between neck injury risk and impact severity parameters in low-speed side collisions.

STUDY DESIGN: In vitro acceleration study on human cadaveric cervical spine specimens. OBJECTIVES: To investigate the correlation between the risk to sustain a structural cervical spine injury and vehicle-related impact severity parameters. SUMMARY OF BACKGROUND DATA: Impact severity parameters, such as the peak acceleration of the vehicle, its mean acceleration, and its velocity change, are often used to predict the whiplash injury risk or to objectify the patient's symptoms even though their correlation to injury is still not well understood. METHODS: In a series of three in vitro experiments, a total of 18 human cadaveric cervical spine specimens were subjected to incremental side accelerations until structural injury occurred. While the duration of the acceleration pulse was kept constant throughout all three experiments, its shape was varied: In Experiment I, the acceleration pulse had a fast increase up to the maximum value and a fast decrease down to zero (fast-fast). Experiment II was characterized by a slow increase and fast decrease (slow-fast), and Experiment III was characterized by a fast increase and a slow decrease (fast-slow). RESULTS: The specimens of Experiment II (slow-fast) sustained structural injury at a significantly higher peak acceleration of the sled (4.6 g on average) than those of Experiments I (fast-fast) (2.6 g) and III (fast-slow) (3.1 g). In contrast, mean acceleration and velocity change of the injuring impacts were almost the same in all three experiments. CONCLUSION: The injury risk to the cervical spine was predictable by the mean acceleration of the sled and since the duration of the crash pulses was constant also by its velocity change but not by its peak acceleration.

Migrating foreign body in the tracheobronchial tree: an unusual case of firework penetrating neck injury.

Firework injuries can manifest themselves in many different ways; usually as an explosive or burn injury. This case describes an unusual presentation of a firework penetrating injury resulting in a sharp coiled metal foreign body travelling through a small entry wound in the neck and subsequently lodging itself in the tracheobronchial tree. A foreign body such as this can potentially travel a considerable distance through the soft tissues and end up in an unsuspecting distant site. There must, therefore, be a high index of suspicion with the appropriate radiological investigations for appropriate management of such cases.

Penetrating neck injuries involving wooden foreign bodies: the role of MRI and the misinterpretation of CT images.

A 12-year-old, boy fell in the bush and suffered a penetrating neck wound. Computed tomography(CT-scan) was performed, but no foreign body was detected inside the wound. The patient returned home after ordinary wound care. About 6 months after the accident, the patient visited hospital, because of inflammatory neck pain. A CT-scan was performed and the foreign body appeared as a high density. Magnetic resonance imaging (MRI) revealed the presence of a large foreign body. Under general anesthesia the wooden (bamboo) foreign body was removed. This case highlights the needs to be aware of the potential for misinterpretation of CT images, especially in acute wooden penetration injury. Its also demonstrates that MRI is a useful adjust to CT in the detection of non-metallic foreign bodies.

[Clinico-roentgeno-functional studies during expert evaluation of work capacity of patients with neurotrophic disorders after war-time neck injuries].

The paper is concerned with a clinico-roentgeno-functional++ study into sequelae of fighting injury to the osseous and soft tissue structures of the neck with the aid of testometric stereoroentgenogrammetry, a method of x-ray topical diagnosis used in fragmentation effects and gunshot injuries, as well as a method of color reading of limb roentgenograms to identify pathomorphological alterations and neurotrophic disorders of the osseous tissue. The pathofunctional alterations related to derangement of the radix structures can be verified by means of using the current methods of functional research: echoosteometry, rheovasography, etc.

[Head and neck injuries among Norwegian soccer players. A neurological, electroencephalographic, radiologic and neuropsychological evaluation].

69 active football (soccer) players and 37 former members of the Norwegian national team were included in a neurological and electroencephalographic (EEG) study to investigate the incidence of head injuries, mainly caused by heading the ball. 3% of the active players and 30% of the former players complained of permanent problems such as headache, dizziness, irritability, impaired memory and pain in the neck. 35% of the active players and 32% of former players had from slightly abnormal to abnormal EEG, as against 13 and 11% of respective matched controls. There were fewer definitely abnormal EEG changes among typical headers (10%) than among "non-headers" (27%). The former players were also subjected to cerebral computed tomography (CT), a neuropsychological examination and a radiological examination of the cervical spine. One third of the players were found to have central cerebral atrophy and 81% to have from mild to severe (mostly mild to moderate) neuropsychological impairment. The radiological examination of the cervical spine revealed a significantly higher incidence and degree of degenerative changes than in a matched control group.

Headrest position during normal driving: implication to neck injury risk in rear crashes.

The gap and relative height of headrest behind drivers were determined for 1915 vehicles approaching an intersection on a two lane road. Vehicle type and headrest adjustment were also evaluated using film of normal driving taken by the Insurance Institute for Highway Safety. Only 10% of drivers had headrests in the most favorable position to prevent neck extension during a rearend crash. 73% of cars had adjustable headrests, but only a quarter were placed in the up position. 83% of the adjustable headrests could have been raised to better protect the driver. Hyge sled tests were run to determine biomechanical responses for the various conditions observed in normal driving. This included three headrest heights and three gaps behind the head. Neck extension from the Hybrid III dummy was normalized to the response for a high, close headrest, and injury risk was assumed to be proportional to neck extension. The current driving situation has a relative injury risk of 3.4 in rearend crashes, compared to 1.0 for the favorable condition. If all adjustable headrests were placed in the up position, the relative risk would be lowered to 2.4, a 28.3% reduction in whiplash injury risk. Public education and vehicle design should address the importance of proper headrest placement for driving safety.
