Operation Walk moving ahead to relieve joint disease

Operation Walkwas started in 1995 by Lawrence D. Dorr, M.D. in Los Angeles, CA. Dr.Dorr is one of the leadingjoint replacement surgeons in the USA

is a private, not-for-profit, volunteer medical services organization which provides freesurgical treatment for patients in developing countries (and occasionally in the US), thathave no access to life-improving care for arthritis or other debilitating bone and jointconditions. Operation Walkalso educates in-country orthopedic surgeons, nurses,physical therapists and other healthcare professionals on the most advanced treatmentsand surgical techniques for diseases of the hip and knee joints. This is done inconjunction with surgeries to help create a lasting contribution to patient care indeveloping countries.

BONE :There are five types of bones in the human body: long, short, flat, irregular and sesamoid.

Long bones are characterized by a shaft, the diaphysis, that is much greater inlength than width. They are comprised mostly ofcompact bone and lesseramounts ofmarrow, which is located within the medullary cavity, andspongybone. Most bones of the limbs, including those of thefingers and toes, are longbones. The exceptions are those of thewrist,ankle and kneecap.

Short bones are roughly cube-shaped, and have only a thin layer of compact bonesurrounding a spongy interior. The bones of the wrist and ankle are short bones,

as are the sesamoid bones. Flat bones are thin and generally curved, with two parallel layers of compact

bones sandwiching a layer of spongy bone. Most of the bones of the skullare flatbones, as is the sternum.

Irregular bones do not fit into the above categories. They consist of thin layers ofcompact bone surrounding a spongy interior. As implied by the name, their shapesare irregular and complicated. The bones of the spine and hips are irregular bones.

Sesamoid bones are bones embedded in tendons. Since they act to hold the tendonfurther away from the joint, the angle of the tendon is increased and thus theleverage of the muscle is increased. Examples of sesamoid bones are the patellaand thepisiform.
