Girdlestone Arthroplasty

Before understanding this Surgical procedure , one needs to know the maifestations of Pressure Sores or Pressure Ulcers .

Pressure Ulcers - Pressure over Bony prominences is called  Pressure sore which leads to Pressure Ulcers.  These are Lesions which proceed to effect the Skin as well in future stages.

The affected part of the bone is  usually removed in such cases .

Femoral Head Osteomyelitis - In this disease , the Femur head is removed due to it getting infected. The first  known case of  Femoral head ostectomy (removal of femur head) was performed by Robert Girdlestone.

Whenever a part of a bone is removed ,  reconstruction is required , especially if the structure excised is associated with a joint.

Arthroplasty means Formation of a joint.

In  the  case of Femoral Head Ostectomy , Arthroplasty is done by the Vastus Lateralis Muscle.

The Insertion of the  Vastus Lateralis Muscle  is removed in the form of a Myocutaneous Flap and is used to reconstruct and reinforce the Hip joint . 

 The muscle is wound around the Hip joint as shown in the figure above. 

The association of Robert Girdlestone with this procedure gave rise to the term Girdlestone Arthroplasty.

This procedure is sometimes followed to treat Trochanteric  Pressure Sores.

The Heart

 Every one at GMC, by now must be quite thorough with the Heart.  So test your self  by visiting this website http://thevirtualheart.org/.  Feel free to move the mouse around on the Heart spinning at the middle of the home page...

Medical Animations

The World Wide Web is the largest resource for Medical students. There are several websites out there waiting to be explored.....

In my previous posts, I have mentioned about visiblebody.com .  It is the perfect guide for anatomy and  also a replacement for Atlases.

There is  another sister website of Visible body , with the url  http://www.argosymedical.com/index.html .

This website has got animations related to the several systems of our body......

 Now is the right time to view the animation of the sectioned  heart  provided by the website as we at GMC have reached the end of thorax.

Not only have they showed the functioning of the Valves but have also coupled the conducting system  with it....  the out come is a  masterpiece.

Several clinical procedures have also been animated. 

Hope you find it useful.
