Total shoulder replacement comprises of replacing the ball and the socket joint. During Hip replacement procedure, The Acetabulur cup is placed in to the acetabulum which commonly referred as the hip socket. The difference is that the prosthesis is implanted in the glenoid instead of the humerus and the cup section is attached to the humerus. These plates are triangular in nature and two of them present in the orbital or the horizontal part of the frontal bone make up the vaults of the orbits and are separated by the median gap which is known as the ethmoidal notch. The problem of using this method is that the repetitive contact between the humeral component and the inferior scapular neck gives rise to a complication known as scapular notching.

If it is made of polythene the cup is cemented in its place but a metal cup is fixed by the metal coating on the outer surface of the cup.One of the most common problems that any ageing man finds is bone damage. Arthritis often causes severe pain to the shoulders. These cups may be of one piece or can be modular. It is thin in nature, more so medially where it is found to be translucent. The orbital plate can be described as a thin plate of bone that forms the horizontal portion of the frontal bone forming the roofs of the orbits. Firstly, the cartilage and he bones are removed from the acetabulum.If a hip is affected by arthritis or is damaged by hip fracture often hip replacement is chosen as the treatment to relive the patient.

These corrugations are a result of the impressions formed by the gyri or the frontal lobe of the brain. Shoulder wholesale tie rod ends replacement is of two types the total shoulder replacement and the reverse shoulder displacement. The Monobloc shells are made of either metal or ultra high molecular weight polyethylene which is commercially coined as UHMWPE. When medication fails to relive the patient of the pain, shoulder prosthesis is used to replace the glenohumeral joint either partly or completely. Subsequently the cup is fixed using cement and friction. The outer surface or the orbital surface is smooth in nature as well as concave while its inner one or the cranial surface is marked by corrugations and depressions.

Arthritis, one of the most painful diseases once contracted makes one suffer immensely and often renders the joints immobile. On the other hand modular cups consist of mainly two pieces - the shell and the linear. The shell is a metal one which has a porous coating outside and a locking mechanism inside which is designed to fit a linear. On the other hand a reverse shoulder replacement is done on patients who are affected by severe rotator cuff tears. The humeral head is replaced by the metal ball the cartilage on the glenoid cavity is replaced by a plastic socket. The arm thus is moved by the deltoid rather than the rotator cuff which is damaged severely
