Osteoporosis is a known risk factor for the development of atraumatic fractures.
Unfortunately, full recovery of skeletal tissues upon reambulation may not be possible [3], increasing the risk of traumatic and atraumatic fractures and, ultimately, compromising quality of life [4].
aTraumatic fractures only; between 3 to 56 years before enrollment in the study; none in the hip (HP) or lumbar spine (LS).
Atraumatic fractures occur typically during the first few months after implantation and the bone hidden inside the femoral component can be either viable or display theoretically diverse pathological changes (e.g. osteonecrosis, renal osteodystrophy, tumor).
The final individual had an atraumatic hip fracture while hospitalised and awaiting transplant.
To the best of our knowledge no report regarding the treatment either of a tibial tubercle pseudarthrosis or of an atraumatic patella fracture after a revision TKA following knee arthrodesis has been published in the literature.
Atraumatic bone fractures occur in 22-38% of patients and neurological complications, including seizures, headache, and neuropathy occur in 19-47% of patients following liver transplantation.
Factors associated with atraumatic patellar fractures include patellar subluxation, improper patellar resection, vascular compromise, component designs and thermal necrosis [ 13, 15].
Western medical treatments for osteoporosis are somewhat effective, but the long-term use of those medicines can result in a number of side effects [ 6- 9], including atraumatic bone fractures caused by bisphosphonates, increased incidence of coronary heart disease, stroke, pulmonary embolism, and ovarian and endometrial cancers caused by estrogen or estrogen replacement therapy.
