DISUSE OSTEOPOROSIS AND HIP PROSTHESIS: SURGICAL IMPLICATIONS, A CASE REPORT

Abstract

In this paper, the authors present a case of osteo-arthtritis of the hip secondary to a septic event

which was surgically treated with a hip prosthesis and complicated by intraoperative fracture due to

a localized disuse osteoporosis. Disuse osteoporosis is an induced rapid bone loss in human

skeleton that occurs mostly after a cord injury or muscle paralysis. Hypodynamia can also be a risk

factor for osteoporosis. In this case the author describe the onset of a femoral intraoperative

fragility fracture in a 58 year old woman affected by an erosive septic osteoarthritis. Our case

suggest that disuse osteoporosis presence should be diagnosed and treated before surgery to help

prevent major surgical or post-operative complications beginning a pharmacological antiresorptive

treatment before the surgery
