Hip Osteonecrosis A Simple Guide To The Condition, Diagnosis, Treatment And Related Conditions

By Kenneth Kee

This book describes Hip Osteonecrosis, Diagnosis and Treatment and Related Diseases
Osteonecrosis is bone death caused by poor blood supply.
It is most common in the hip and shoulder, but can affect other large joints such as the knee, elbow, wrist and ankle.
While osteonecrosis affects people of all ages, it most often occurs between the ages of 40 and 65.
Men develop osteonecrosis more often than women.
Causes
Osteonecrosis of the hip is a painful disorder that occurs when the blood supply to the bone is interrupted.
Because bone cells die without a blood supply, osteonecrosis can ultimately lead to destruction of the hip joint and arthritis.
1.Injury — Hip dislocations, hip fractures, and other injuries impair circulation to the femoral head
2.Alcoholism
3.Corticosteroid medicines
4.Other medical disorders:
a.Caisson disease ("the bends")
b.Sickle cell disease,
c.Myeloproliferative disorders,
d.Gaucher's disease
e.Systemic lupus erythematosus
f.Crohn's disease,
g.HIV or taking HIV drugs
h.Radiation therapy
i.Legg-Calve-Perthes disease
j.Arterial embolism,
k.Clotting disorders
l.Vasculitis
Symptoms
There are no symptoms in the early stages.
As bone damage worsens, the patient may have these symptoms:
1.Pain in the joint that may increase over time and becomes severe if the bone collapses
2.Pain that occurs even at rest
3.Limited range of motion
4.Groin pain, if the hip joint is affected
5.Limping, if the disorder occurs in the leg
Osteonecrosis develops in stages and hip pain is typically the first symptom.
This may lead to a dull ache or throbbing pain in the groin or buttock area.
As the disease progresses, it will become more difficult to stand and put weight on the affected hip, and moving the hip joint will be painful.
How long it takes for the disease to progress through these stages varies from several months to over a year.
Diagnosis:
The patient will be asked about the symptoms and medical history.
The patient will go through a detailed physical examination, with the hip and leg maneuvred into various positions.
Increased pain during certain movements may be a sign of osteonecrosis.
After the exam, the doctor will order one or more of these tests:
1.X-ray
2.MRI
3.CT scan
An x-ray will be taken to examine degradation to the femoral head.
Occasionally the patient may be asked to undertake an MRI scan to show early changes in the bone that may not show up in an x-ray.
Treatment
If the doctor knows the cause of osteonecrosis, part of the treatment will be aimed at the underlying disorder.
If a blood clotting disorder is the cause, treatment will consist, in part, of clot-dissolving medicine.
If the disorder is caught early, the patient will take pain relievers and limit use of the affected area.
This may include using crutches if the hip, knee, or ankle is affected.
The patient may need to do range-of-motion exercises.
Non-surgical treatment
Unfortunately there are no non-surgical treatments that will reverse osteocronosis.
Medication or the use of crutches can relieve pain, however the only corrective approach is through surgical means.
1.A bone graft
2.A bone graft along with its blood supply (vascularized bone graft)
3.Cutting the bone and changing its alignment to relieve stress on the bone or joint (osteotomy)
4.Total joint replacement
5.Removing part of the inside of the bone (core decompression) to relieve pressure and allow new blood vessels to form
Rehabilitation
Surgery is followed by a prolonged course of physiotherapy, a rehabilitation in order to achieve the best possible result (at least half an hour per day for 6 months).
Most patients are able to drive 4 to 6 weeks after surgery.

Introduction

I have been writing medical articles for my blog http://kennethkee.blogspot.com (A Simple Guide to Medical Disorder) for the benefit of my patients since 2007.

My purpose in writing these simple guides was for the health education of my patients.

Health Education was also my dissertation for my Ph.D (Healthcare Administration).

I then wrote an autobiolographical account of his journey as a medical student to family doctor on his other blog http://afamilydoctorstale.blogspot.com.

This autobiolographical account A Family Doctor’s Tale was combined with my early A Simple Guide to Medical Disorders into a new Wordpress Blog A Family Doctor’s Tale on http://kenkee481.wordpress.com.

From which many free articles from the blog was taken and put together into 800 eBooks.

Some people have complained that the simple guides are too simple.

For their information they are made simple in order to educate the patients.

The later books go into more details of medical disorders.

The first chapter is always from my earlier blogs which unfortunately tends to have typos and spelling mistakes.

Since 2013, I have tried to improve my spelling and writing.

As I tried to bring the patient the latest information about a disorder or illness by reading the latest journals both online and offline, I find that I am learning more and improving on my own medical knowledge in diagnosis and treatment for my patients.

Just by writing all these simple guides I find that I have learned a lot from your reviews (good or bad), criticism and advice.

I am sorry for the repetitions in these simple guides as the second chapters onwards have new information as compared to my first chapter taken from my blog.

I also find repetition definitely help me and maybe some readers to remember the facts in the books more easily.

I apologize if these repetitions are irritating to some readers.

Chapter 1

Hip Osteonecrosis

What is Hip Osteonecrosis?

Osteonecrosis is the bone death caused by poor blood supply.

It is most frequent in the hip and shoulder, but can affect other large joints such as the knee, elbow, wrist and ankle.

While osteonecrosis involves people of all ages, it most often happens between the ages of 40 - 65.

Men form osteonecrosis more often than women.

What are the causes of Hip Osteonecrosis?

Causes

Osteonecrosis of the hip is a painful disorder that happens when the blood supply to the bone is interrupted.

Since bone cells die without a blood supply, osteonecrosis can finally result in the destruction of the hip joint and cause arthritis.

While it can happen in any bone, osteonecrosis most often involves the hip.

The hip is a ball-and-socket joint.

The socket is formed by the acetabulum, which is part of the large pelvis bone.

The ball is the femoral head which is the upper end of the femur (thighbone).

A slippery tissue called articular cartilage covers the surface of the ball and the socket.

It provides a smooth, low friction surface that helps the bones glide easily across each other.

Osteonecrosis of the hip happens once the blood supply to the femoral head is blocked or stopped.

Without sufficient nourishment, the bone in the head of the femur dies and slowly collapses.

The articular cartilage covering the hip bones also collapses, leading to disabling arthritis.

With osteonecrosis, the bone in the head of the femur slowly dies.

While it is not always known what causes the
