BACKGROUND Fractures of the clavicle are common injuries. The complications have been well documented in the literature. CASE PRESENTATION Despite it close proximity to the sternocleidomastoid muscle and myositis ossificans recognised as a known complication of any fracture, the two have never previously been described in association secondary to a fracture of the clavicle. We present a case ...

Esophageal perforation is a serious possible complication after anterior cervical discectomy and fusion (ACDF). It usually occurs during the first postoperative day. Esophageal perforation is a potentially life-threatening complication. A 63-year-old man who underwent ACDF 8 years prior visited our emergency room with recurrent aspiration pneumonia, fever, dysphagia and neck pain. Endoscopic st...

[Purpose] This study examined the changes in the thickness of the deep cervical flexor according to the contraction intensity of the masticatory muscle during deep cervical flexor training. [Subjects and Methods] Twenty healthy adults were randomly selected and the thicknesses of their longus colli and sternocleidomastoid were measured with ultrasound when the masticatory muscle contracted duri...

[Purpose] This study examined differences in neck muscle activity in two different head positions during tackles with the aim of contributing to the prevention of sports injuries. [Subjects] The subjects were 28 male high-school rugby players. [Methods] Two tackle positions were considered: a head-up position and a head-down position. Muscle activities of the sternocleidomastoid muscles and the...

The arterial baroreflex is crucial for short-term blood pressure control - abnormal baroreflex function predisposes to syncope and falling. Hypersensitive responses to carotid baroreflex stimulation using carotid sinus massage (CSM) are common in older adults and may be associated with syncope. The pathophysiology of this hypersensitivity is unknown, but chronic denervation of the sternocleidom...
