The radial groove (also known as the musculospiral groove, radial sulcus, or spiral groove) is a broad but shallow oblique depression for the radial nerve and deep brachial artery. It is located on the center of the lateral border of the humerus bone. [ 1 ]
The humerus (/ ˈ h juː m ər ə s /; pl.: humeri) is a long bone in the arm that runs from the shoulder to the elbow.It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.
A fossa (from the Latin "fossa", ditch or trench) is a depression or hollow, usually in a bone, such as the hypophyseal fossa, the depression in the sphenoid bone. [15] A meatus is a short canal that opens to another part of the body. [16] An example is the external auditory meatus. A fovea (Latin: pit) is a small pit, usually on the head of a ...
Upper arm - a fracture of the bone; Elbow - entrapment of the nerve; Wrist - elbow deformity and soft-tissue masses; Axilla - here the most common cause is compression. However, a dislocation of the humerus is a possible factor as well. It could also be due to brachial plexus compression.
Joint pain is a common symptom we all experience at some point or another. Painful joints can have a significant impact on quality of life and the ability to do daily activities.
[58] [59] Loss of bone density (bone demineralization), thought to be due to lack of input from weakened or paralysed muscles, can increase the risk of fractures. [60] Conversely, a poorly understood phenomenon is the overgrowth of bone tissue in soft tissue areas, called heterotopic ossification. [61]
The pressure keeps rising due to the non-compliant fascia in the compartment. [5] This cycle can cause tissue ischemia, a lack of oxygen, and necrosis, or tissue death. [6] [5] [43] Paresthesia, or tingling, can start as early as 30 minutes after tissue ischemia begins. [45] Permanent damage can occur 12 hours after the injury starts. [45]
This is usually due to direct trauma to the shoulder or neck region as a result of vehicular accidents, occupational injuries or sports injuries. The brachial plexus may also be compressed by surrounding damaged structures such as bone fragments or callus from the clavicular fracture, and hematoma or pseudoaneurysm from vascular injury.
