Question: Which body part is the most common location for injuries?

Cross country running places an extreme amount of strain on the body, which can lead to many injuries.
However, if a runner has the right pair of shoes, this strain can be minimized.
Some of the most common running injuries are blisters, twisted ankles, knee injuries, and shin splints. 
Treatment commonly consists of compression wraps, warming pads and icing.
Rest, icing, compression and elevation (which is often referred to by the mnemonic RICE or sometimes PRICE with P being "protection") are recommended by physicians for the treatment of soft tissue damage; sprained ankles are one of the most common soft tissue injuries.
RICE is intended to reduce blood and fluid flow to the affected region of the body, in this case the ankle. 
Extensor tendon compartments of the wrist are locations in the wrist that contain tendons.
Wrist joint anatomy is one the most complex of all the body joints.
There are several important tendons that cross the wrist.
These tendons originate from muscles that are localized in the forearm.
The extensor tendons travel in the posterior or dorsal part of the wrist through a series of tunnels called compartments.
The extensor tendons are held in place by the extensor retinaculum.
As the tendons travel over the posterior aspect of the wrist they are protected with synovial tendon sheaths.
These sheaths reduce the friction for the extensor tendons as they traverse the osseousfibrous tunnels that are formed by the attachment of the extensor retinaculum to the distal radius and ulna.
Because of their poorly protected anatomic location injuries to the extensor tendons of the fingers are common.
According to the affected anatomic regions, the type of injury, deformity, and surgical outcome will be different.
Because of this it is very important to classify the tendon injuries into anatomic zones called compartments.
The wrist extensor compartments correspond to Zone VII of the Verdan's Zone System. 
Usually hip dislocation occurs when the head of the femur dislodges from its socket form the pelvis.
In most patients, the femur shifts out of its socket in a posterior dislocation direction.
The hip is now in a position where it is twisted in toward the middle of the body.
The femur could also shift in an anterior direction which the hip will twist outward and away from the middle of the body.
This dislocation is very painful and patients are unable to move when it occurs.
Due to the dislocation, there could be some nerve damage resulting in loss of feeling in the foot or ankle.
To actually dislocate a healthy hip, a great amount of force needs to be applied.
Motor vehicle accidents are the most common ways that hip dislocations occur.
Falls from a height, such as a ladder, can also generate enough force to dislocate a hip.
In older individuals, even a slight fall could cause this type of injury.
Wear and tear that the body undergoes throughout the years leads to increased incidents of hip dislocation in the older population.
Hip injuries in sports are also quite common.
In contact sports such as rugby and American football hip dislocation is a result of great amounts of force applied to the body during contact and collision.
In other sports such as water skiing, skiing/snowboarding, gymnastics, and basketball these injuries are less common because there are fewer collisions and less contact.
However, when the amount of force to the hip joint is greater than the muscles of the hip can compensate for, hip injuries can still occur.
Several other injuries are also associated with hip dislocation.
Fractures in the pelvis and legs, and minor back or head injuries can also occur, along with a hip dislocation, that is caused by a fall or athletic of injury. 
Diaphragmatic injuries are present in 1–7% of people with significant blunt trauma and an average of 3% of abdominal injuries.
A high body mass index may be associated with a higher risk of diaphragmatic rupture in people involved in vehicle accidents.
It is rare for the diaphragm alone to be injured, especially in blunt trauma; other injuries are associated in as many as 80–100% of cases.
In fact, if the diaphragm is injured, it is an indication that more severe injuries to organs may have occurred.
Thus, the mortality after a diagnosis of diaphragmatic rupture is 17%, with most deaths due to lung complications.
Common associated injuries include head injury, injuries to the aorta, fractures of the pelvis and long bones, and lacerations of the liver and spleen.
Associated injuries occur in over three quarters of cases.
