the use of anabolic steroids effects recovery. A updated Cochrane review (2022) involving over 4000 patients found evidence that gait training, balance and functional tasks training to be particularly effective when compared to conventional care. There is also moderate-certainty evidence that rehabilitation after hip fracture surgery, when delivered by a multidisciplinary team and supervised by an appropriate medical specialist, results in fewer cases of 'poor outcome', like death and deterioration in residential status. Nutrition supplementation Oral supplements with non-protein energy, protein, vitamins and minerals started before or early after surgery may prevent complications during the first year after hip fracture in aged adults; without seemingly effects on mortality. Surgical complications Deep or superficial wound infection has an approximate incidence of 2%. It is a serious problem as superficial infection may lead to deep infection. This may cause infection of the healing bone and contamination of the implants. It is difficult to eliminate infection in the presence of metal foreign bodies such as implants. Bacteria inside the implants are inaccessible to the body's defence system and to antibiotics. The management is to attempt to suppress the infection with drainage and antibiotics until the bone is healed. Then the implant should be removed, following which the infection may clear up. Implant failure may occur; the metal screws and plate can break, back out, or cut out superiorly and enter the joint. This occurs either through inaccurate implant placement or if the fixation does not hold in weak and brittle bone. In the event of failure, the surgery may be redone or changed to a total hip replacement. Mal-positioning: The fracture can be fixed and subsequently heal in an incorrect position; especially rotation. This may not be a severe problem or may require subsequent osteotomy surgery for correction. Prognosis Hip fractures are very dangerous episodes, especially for elderly and frail patients. The risk of dying from the stress of the surgery and the injury in the first thirty days is about 10%. At one year after fracture, this may reach 30%. If the condition is untreated the pain and immobility imposed on the patient increase that risk. Problems such as pressure sores and chest infections are all increased by immobility. The prognosis of untreated hip fractures is very poor. Post operation Among those affected over the age of 65, 40% are transferred directly to long-term care facilities, long-term rehabilitation facilities, or nursing homes;
