The management of osteoporotic acetabular fractures: Current methods and future developments.

Acetabular fractures in the elderly are challenging. Management is complicated by patients' poor physiological status and osteoporotic bone. Analysis of the management of these patients must be separated from the treatment of younger patients. Conservative management continues to have a role in patients who sustain fractures that are non-displaced and are considered stable with weight bearing mobilisation, and in those patients considered too medically frail to undergo surgical intervention. The mainstay of current surgical intervention is open reduction and internal fixation (ORIF) and variations of ORIF and total hip arthroplasty (THA), or fix and replace. Fix and replace is being increasingly favoured in those patients who display poor prognostic factors for long term joint survival after ORIF. Percutaneous fixation has the theoretical benefits of minimally invasive surgery and the potential to make any subsequent THA less complicated. However, it requires specialised fluoroscopic skills and is not suitable for all fracture patterns. There are a number of developments being reported. The use of a reinforcement ring and THA in has been reported in a number of centres, as has the use of trabecular metal acetabular implants. A coned hemi pelvic prosthesis and THA has been described in our centre, with promising early results. The potential for 3D printing to improve preoperative planning and reduce intra-operative time is also being explored. The aim of this review is to provide a summary of the literature supporting current and future treatment methods, tips on reduction techniques and an overview of the treatment algorithm of these patients in our unit.
