 Good morning, I am Dr. Chirag Thonsay, Consultant and Orthopedic Surgeon at Vitramospital, Bangalow. Bone death or AVAS-2R Necrosis is a condition where the blood supply to a particular bone reduces. Further on, leading to the necrosis or death of that bone tissue, which would further lead to the collapse of that bone or joint and cause arthritis of the joint. AVAS-2R Necrosis usually affects individuals between 30 to 40 years of age group. There are various reasons why AVAS-2R Necrosis can occur. Either a dislocation of a joint, trauma, excessive intake of alcohol or steroid abuse. In the recent times, you have seen an upsurge in the incidence of AVAS-2R Necrosis especially in the younger individuals. It could be related to the COVID related treatments where one would have been treated with excessive steroid medications which would further lead on to a bone death or AVAS-2R Necrosis. Patients presenting with AVAS-2R Necrosis can have different symptoms, they could have different complaints. Ideally, one would complain of pain in the thigh or the hip joint, typically a dilating pain sometimes in the day which would further all progress to a constant pain especially while walking and doing the routine activities. Some patients do complain of pain in the night which is called the night pains. This pain could be occasional initially as the disease advances or progresses one could have a constant pain throughout the day. It's very important that we detect AVAS-2R Necrosis at its earliest stage so that to prevent any further damage to the bone tissue or the joint. We all know that the hip joint consists of a boil and socket joint where the boil is the bone which is affected in AVAS-2R Necrosis. As we know, AVAS-2R Necrosis is because of the reduction of the blood supply to a particular area of the bone. In AVAS-2R Necrosis, the blood supply to the hip joint gets reduced further leading to the death of the bone tissue in the head and leading to a collapse of this bone further on leading to arthritis of the hip joint. There are various stages of AVAS-2R Necrosis, Stage 1 to Stage 4. Stage 1 would be a milder form of AVAS-2R Necrosis, the initial stages. And Stage 4 would be an advanced stage of AVAS-2R Necrosis which would require surgical interventions. Post-COVID recovery phase is very important that we detect this condition of AVAS-2R Necrosis at a very early stage. And anyone who is in the phase of COVID recovery and has undertaken steroid treatment is advised to see the doctor, seek an advice and to do the necessary investigations to detect AVAS-2R Necrosis especially of the hip at a very early stage to prevent further catastrophes.
