o Femoral Neck fracture
o Inter-trochanteric fracture
Repeated stress
o Degenerative joint disease (DJD) of the
Hip
Deformities
o Congenital dislocation of the Hip (CDH)
/ Developmental dysplasia of the Hip (DDH).
Mechanisms Hip injury-
Hip Strain is an overuse or injury that
tears or stretches the muscle fibers.
Most of the time, muscle strains in the
hip area occur when a stretched
muscle is forced to contract suddenly.
A fall or direct blow to the muscle,
overstretching and overuse can tear
muscle fibers, resulting in a strain.

Types Of Hip Injury-
Bursa is a fluid filled sac that allows smooth motion between two uneven surfaces.
Hip bursitis is a common problem that causes pain over the outside of the upper thigh.
When the bursal sac becomes inflamed, each time the tendon has to move over the bone, pain results. Because patients with hip bursitis move this tendon with each step, hip bursitis symptoms can be quite painful. 8

Anatomy of Hip-jointRecent Advancement
Hip Surgery And Hip-Replacement
The hip joint is a ball and socket joint, formed by the head of the Femur (thigh bone) and the acetabulum of the pelvis. The dome-shaped head of the femur forms the ball, which fits snuggly into the concave socket of the acetabulum. The hip joint is a very sturdy joint, due to the tight fitting of the bones and the strong surrounding ligaments and muscles.

Anatomy of Hip-joint
Bones of the hip joint The hip joint capsule Ligaments of the hip joint Labrum of the hip joint Muscle Groups surrounding the hip joint. Neuro-vascular Components.
Vital Components of Hip-joint -
The ilium: This is the largest area of the hip bones. The ischium: The ischiumconsists of 2 broad curves of bone, one on each side, which lie below the ilium, The pubis: The pubis is the front-most area of the hip bones. It attaches to the iliumon the sides and the ischiumon the bottom.

Age. The rate increases for people 65 and older. Gender. Women have two to three times as many hip fractures as men. Heredity. A family history of fractures in later life, particularly in Caucasians and Asians. A small-boned, slender body. Nutrition. A low calcium dietary intake or reduced ability to absorb calcium. Personal habits. Smoking or excessive alcoholuse. Physical impairments. Physical frailty, arthritis, unsteady balance, and poor eyesight. Mental impairments. Senility, dementia, e.g., Alzheimer's disease.Weakness or dizziness from side effects of medication

Hip Xray Usually identifies Fracture and
Dislocation Hip MRI (T1-weighted) Indicated for high suspicion despite normal XRay Test Sensitivity: 100% Does not require delay after injury
Hip Bone Scan with Technetium Tc99m Polyphosphate Test Sensitivity: 98% Delay scan at least 72 hours after time of injury 24
Imaging
MR Arthrogram

An MRI may identify a
hip fracture otherwise missed on plain X-ray.
DiagnosisRecent Advancement

25
Subjective Assessment Pain localized in hip region Exaggerated gait pattern (limp) Increase in pain when weight barring Reduction in the degree of ROM As the degeneration of the joint worsen, individual may be awakened at night with pain Bone spurs may occur
26
Objective Assessment Gait pattern – Adaptive walking pattern that reduces pressure on the affected side. Muscle atrophy – Muscles in affected area are not used as much due to pain, therefore, use-it-or-lose-it applies. Active Range Of Motion – Limited ROM, stiffnessPassive ROM – End feels causes severe pain X-ray – clear degeneration of the bone MRI – determines underlying complications (e.g.avascular necrosis)

Alternative Names
• Hip arthroplasty;
• Total hip replacement;
• Hip hemiarthroplasty.
Definition of Hip joint replacement:
Hip joint replacement is surgery to replace all or part of the hip joint with an artificial joint. The artificial joint is called a prosthesis.
34
Description:The artificial hip joint has 4 parts:A. A socket that replaces your old hip
socket. The socket is usually made ofmetal.
B. The liner fits inside the socket. It isusually plastic, but some surgeons arenow trying other materials, likeceramic and metal. The liner allowsthe hip to move smoothly.
C. A metal or ceramic ball that willreplace the round head (top) of yourthigh bone.
D. A metal stem that is attached to theshaft of the bone to add stability tothe joint.
HIP REPLACEMENT
35
Types of Hip Replacement
Traditional (Conventional) Hip ReplacementTraditional hip replacement surgery involves making a 10- to 12-inch incision on the side of the hip. The muscles are split or detached from the hip, allowing the hip to be dislocated. Minimally Invasive Hip ReplacementMinimally invasive hip replacement surgery allows the surgeon to perform the hip replacement through one or two smaller incisions (2 to 4 inch).

Hip pain limits your everyday activities such as walking or bending. Hip pain continues while resting, either day or night. Stiffness in a hip limits your ability to move or lift your leg. You have little pain relief from anti-inflammatory drugs or glucosamine sulfate. You have harmful or unpleasant side effects from your hip medications. Other treatments such as physical therapy or the use of a gait aid such as a cane do not relieve hip pain.

Difference Between Traditional and
Minimally Invasive Hip Replacement
Surgery-
Traditional Hip Replacement Surgery-
Proven in clinical studies and successfully performed for decades
Allows surgeon full visualization of operative area
Larger incision/ scar (12-18 inches)
More disruption of muscles and tissues
May lead to more blood loss .
May lead to a extendededhospital stay/ recovery time
Minimally Invasive Hip Replacement Surgery-
Long-term effects and success are being studied
Smaller incisions/ Scars (2-4 inches)
Potentially less disruption of muscles and tissues
May lead to less blood loss
Potential for less postoperative pain
May lead to a shortened hospital stay/ recovery time

PROSTHESIS TYPE
45
The major problems with standard hip replacements are: Wearing out of plastic sockets. Loosening of the bond between the implant and bone. In time the cement can crack, directly resulting in loosening. Secondly, the body reacts to minute fragments of cement, plastic or metal, and attempts to remove them, and also removes bone adjacent to the particles, leaving the bone structurally weakened. If the implant loosens, a second surgery may become necessary to reattach it.
Recent Advancement
Hip Surgery And Hip-Replacement
46
There has been much research into theloosening problem. This led to thedevelopment of the: Cementless Hip Replacement in whichthe surface of the metal parts is porous, andlooks like coral. Bone can grow into themetal pores and bond the implant to thebone without the use of cement. The AML Total Hip Replacement (DePuy/ Johnson & Johnson) is the most widely used cementless implant in the world, and has the longest track record (since 1978). Cement is still used with very soft bones,regardless of age.

The Don'ts Don't cross your legs at the knees for at least 8 weeks. Don't bring your knee up higher than your hip. Don't lean forward while sitting or as you sit down. Don't try to pick up something on the floor while you are sitting. Don't turn your feet excessively inward or outward when you bend down. Don't reach down to pull up blankets when lying in bed. Don't bend at the waist beyond 90°. Don't stand pigeon-toed. Don't kneel on the knee on the unoperated leg (the good side). Don't use pain as a guide for what you may or may not do.The Dos Do keep the leg facing forward. Do keep the affected leg in front as you sit or stand. Do use a high kitchen or barstool in the kitchen. Do kneel on the knee on the operated leg (the bad side). Do use ice to reduce pain and swelling, but remember that ice will diminish sensation. Don't apply ice directly to the skin; use an ice pack or wrap it in a damp towel. Do apply heat before exercising to assist with range of motion. Use a heating pad or hot, damp towel for 15 to 20 minutes. Do cut back on your exercises if your muscles begin to ache, but don't stop doing them!
Rehabilitations
Recent Advancement
Hip Surgery And Hip-Replacement
53
An appropriate and progressive rehab program should be started early in the treatment of patients with hip injuries. Several rehab techniques are available, none of which require expensive equipment or great time commitments. Selecting the best exercise approach for each patient’s hip problem is not difficult. A closely monitored home exercise program allows the doctor of Chiropractic to provide cost-efficient, yet very effective rehabilitation care.
Rehabilitations
ComplicationsRecent Advancement
Hip Surgery And Hip-Replacement
The most common hip problem that may arise soon after hip replacement surgery is hip dislocation. The most common later complication of hip replacement surgery is an inflammatory reaction Heterotopic bone formation (bone growth beyond the normal edges of bone). Leg length discrepancy which may be caused by the prosthesis or by weakness in the muscles of the hip Breakage of the prosthesis which may require an additional surgery for replacement Wound infection. 54
55
Other (systemic) complications include:
Blood clots in the deep veins of the leg (deep vein thrombosis or DVT) that can move to the lung and cause pulmonary embolism (PE) Urinary infection or difficulty with urination Pneumonia that may result from difficulty taking deep breaths and coughing after anesthesia.

Prognosis Of Hip-Replacement-
58
Hip replacement surgery results are usually excellent. Most or all of your pain and stiffness should go away. Some people may have problems with infection or loosening, or even dislocation, of the new hip joint. Over time -- sometimes as long as 20 years -- the artificial hip joint will loosen. A second replacement may be needed. Younger, more active, people may wear out parts of their new hip. It may need to be replaced before the artificial hip loosens.
