2. Femur
Also called the thigh bone, the femur is the bone for the upper portion of
the leg. It is the longest, largest and heaviest bone of the body.
Femoral head
The femoral head is the top ball-like end of the femur. The femoral head
fits into the socket of pelvic bone to form the hip joint. Cartilage on the
head cushions the joint in the socket, allowing smooth rotation.
Femoral neck
The femoral neck supports the femoral head. Its length allows for
maximum leverage and rotation.
Pelvis
Two hip bones come together to form a griddle at the bottom of the body
called the pelvis. It carries and transmits weight from the upper body to
lower limbs in standing or sitting positions. Each hip bone is divided into
three sections. The illium, the ischium and the pubis
Acetabulum
This cavity in the pelvis forms the socket that holds the femoral head.
Acetabular labrum
Also called the acetabular lip , this soft tissue extends and forms the socket
Femoral head ligament
The ligament connects the femoral head to the acetabulum.
Femoral Ligaments
These three strong ligaments attach the femur bone to the pelvis. They
stretch over the joint to strengthen and support it.

3. Overview
This minimally-invasive surgical procedure is used to identify and correct
problems in the hip joint. Such as a torn labrum or damaged articular cartilage,
that commonly result from femoral-acetabular impingement
Preparation
The patient is positioned so that front of the hip is clearly visible to the
physician, and the area is cleaned and sterilized. Local anesthesia is
administered to numb the injection site, and a sedative is provided to relax the
patient. General anesthesia may sometimes be used.
Accessing the Joint
Two to five small incisions are made along the sides and front of the hip joint.
An arthroscopic camera and other tools are inserted through these incisions .
The camera allows the surgeon to view the procedure on a monitor.
Examining the joint
The surgeon injects fluid into the space around hip joint to expand he joint and
provide a clear view. The surgeon carefully examines the joint to look for signs
of damage.
Repairing the joint
Once the hip has been examined the physician may use one or more of the
arthroscopic tools to correct any problems. Bony growth may be filled down
to allow for proper joint movement. A torn labarum can be repaired with
sutures or shaved down . Loose or damaged cartilage may be removed.
End of Procedure and Aftercare
The incisions are closed with sutures and surgical staples. The hip is bandaged.
The patient will be given pain relievers and should be able to leave hospital
within a day

4. Overview
The surgery replaces diseased and damaged portions of the hip with implants
designed to restore function to the hip joint.
1.Damaged Bone Removed
After the femur (thigh bone) is separated from the hip socket , the damaged ball is
removed.
2.Hip Socket Cleaned
Damaged cartilage and bone are removed from the hip socket.
3.Metal Shell Inserted
A metal shell is pressed into the hip socket. The shell may be held in place wth bone
cement and screws.
4.Liner Inserted
A plastic liner is locked into the metal shell, and the artificial socket is complete.
5.Femur Prepared
The surgeon now focuses on the femur implant. First , the end of the femur is
hollowed out.
6.Implant Inserted
The metal implant is placed into the top of thigh bone . Bone cement may be used.
7. Ball Attached
A metal or ceramic ball component is attached to the stem
8.End of Procedure
The new ball and sockets components are joined to form the new hip joint
