Stress fractures in dinosaur bones can be identified by looking for bulges on the shafts of bones that face toward the front of the animal. When X-rayed, these bulges often show lines of clear space where the X-rays have a harder time traveling through the bone.
Fractures of the fingers occur when the finger or hands hit a solid object. Fractures are most common at the base of the little finger (boxer's fracture). Nerve injuries occur as a result of trauma, compression or over-stretching. Nerves send impulses to the brain about sensation and also play an important role in finger movement.
A bone fracture may be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture.

An acute injury can be traced back to a specific incident, causing immediate pain and often swelling. [15] [16] On the other hand, a Chronic injury does not have a distinct origin, it develops slowly, is persistent and long lasting, and it is accompanied by dull pain, aches or soreness.

The rest of the finger bones (the middle finger bones, and the proximal or innermost finger bones) are divided into base, shaft, and condyle (outer end). Extensive tendons surround the joints and move the fingers. On the front and back of each finger is a digital nerve and artery; these can also be injured when the finger is broken. [1]
Tendinitis is a type of overuse injury to the tendons, which demonstrates signs of inflammation of tendons around a joint. Tendinitis is the most common cause of shoulder pain and also leg pain . Tendinitis occurs when there is repetitive stress on the subacromial bursa, which causes the bones to make contact with the tendons and irritate them.
Pain, tenderness, bruising, swelling, displacement of the bones. [3] Complications: Compromised blood circulation; malunion, long-term pain, degenerative joint disease, infection [3] Usual onset: Sudden [3] Causes: Stubbing or crushing [3] over-extending a toe joint, stress fracture [3] [4] Diagnostic method: Visualisation, X-rays [3] Treatment
A jammed finger can generally be diagnosed by a physical examination. Bone or joint deformity may indicate potential dislocations or fractures. [6] The basic structure of the finger includes three bones with joints in between each. [9] The joint closest to the tip is the distal interphalangeal (DIP) joint.
