Wandering spleen (or pelvic spleen) is a rare medical disease caused by the loss or weakening of the ligaments that help to hold the spleen stationary. Symptoms and signs
Although symptoms include an enlargement in the size of the spleen, or a change from the spleens original position to another location, usually in either other parts of the abdomen or into the pelvis. This ability to move to other locations is commonly attributed to the spleens pedicle being abnormally long.Physical factors may cause ischuria, constipation, as well as numerous spleen-related diseases such as hypersplenism, thrombocytopenia, and lymphoma. Blocking of the arteries and torsion (twisting that interrupts the blood supply to that organ) in the spleen can also result in abdominal pain or swelling. However, lack of visible symptoms — except in incidents of abdominal pain — makes the disease difficult for doctors to diagnose, though medical imaging techniques such as medical ultrasonography, magnetic resonance imaging, or computed tomography can be used to confirm its occurrence. Characteristics of the disorder include the loss, weakening, or malformation of the ligaments that help to keep the spleen located in the upper left part of the abdomen. Cause
Though not a genetic disease, wandering spleen is often found at birth. It can occur in  adults as the result of injuries and other similar conditions that cause the ligaments to weaken, such as connective tissue disease or pregnancy. Wandering spleen (splenoptosis) predisposes the spleen to complications such as torsion, splenic infarction, pancreatic necrosis and rarely pseudocyst formation.
Angle fractures are defined as those that involve a triangular region bounded by the anterior border of masseter muscle and an oblique line extending from the lower third molar (wisdom tooth) region to the posteroinferior attachment of the masseter muscle. Body
Fractures of the mandibular body are defined as those that involve a region bounded anteriorly by the parasymphysis (defined as a vertical line just distal to the canine tooth) and posteriorly by the anterior border of the masseter muscle. Parasymphysis
Parasymphyseal fractures are defined as mandibular fractures that involve a region bounded bilaterally by vertical lines just distal to the canine tooth. Symphysis
Symphyseal fractures are a linear fractures that run in the midline of the mandible (the symphysis). Fracture type
Mandibular fractures are also classified according to categories that describe the condition of the bone fragments at the fracture site and also the presence of communication with the external environment. Greenstick
Greenstick fractures are incomplete fractures of flexible bone, and for this reason typically occur only in children. This type of fracture generally has limited mobility. Simple
A simple fracture describes a complete transection of the bone with minimal fragmentation at the fracture site. Comminuted
The opposite of a simple fracture is a comminuted fracture, where the bone has been shattered into fragments, or there are secondary fractures along the main fracture lines. High velocity injuries (e.g. those caused by bullets, improvised explosive devices, etc...) will frequently cause comminuted fractures. Compound
A compound fracture is one that communicates with the external environment.
