"Clavicular Duplication Causing Thoracic Outlet Obstruction": Unique Presentation of Unreported Association between
1Department of Orthopadics and Trauma, North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences, Shillong, Meghalaya, India.
Abstract:
There are only few reports of clavicular duplication in the literature and all authors have agreed that duplicated clavicles are clinically insignificant. This is the first report of this unique association. A 22-year-old female student reported with features of neurogenic thoracic outlet syndrome mainly involving C8-T1 components of the brachial plexus, seemingly originating from involvement in costo-clavicular space. Radiograph of the shoulder revealed clavicular duplication. Neuro-physiological studies corroborated the diagnosis. Patient responded well to conservative treatment and was in follow-up for 1 year. Radiograph of the shoulder should be included in the workup of neurogenic thoracic outlet syndrome and anomalies of clavicle should be looked into and ruled out along with other common causes. Patient and symptom directed approach with dedicated physiotherapy and occupational therapy is required for optimum outcome.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
