Under the bottom of the rearfoot is a fat pad that normally cushions us and protects the heel as we walk. When walking, there is a force equal to nearly 2.5 times body weight on the heel during heel strike, so it should really be obvious why we need that fat pad. Not having that fat pad there would be poor shock reduction which may result in several disorders because of that poor cushioning. The commonest is simply soreness beneath the rearfoot. The pain will mostly show up on standing instead of as much on palpation. It isn't really a frequent source of heel pain, but it is a vital reason as it might regularly be mistaken for heel spurs along with other causes. Usually it is not difficult to identify as there is certainly just virtually no cushioning under the heel and you will easily notice the bone.
The causes of fat pad atrophy are not totally clear. The fat pad does waste away with age normally and in many it just atrophies more quicker. Some people just appear to develop this while others usually do not. It's not necessarily related to bodyweight problems. It can happen in a number of arthritis disorders and athletes as a result of many years of beating on the heel can be at a higher risk this problem. Individuals with a higher arched foot (pes cavus) will also get a shifting of this fat pad which may give a similar issue to the atrophy.
The only method to treat fat pad atrophy is usually to replace the fat or substitute for the fat. This can be inserted in operatively or a cushioning heel pad in the footwear used that has a similar uniformity to the missing fat pad. Cushioned shoes could also be used with or without extra cushioning. Operatively this can be an injectable fillers or perhaps an autograft making use of your own fat tissue.
