Early weight-bearing after acetabular fractures in the older patient: a systematic review

While the incidence of acetabular fractures keeps rising among our older patient population, age-specific rehabilitation guidelines are lacking. Post-surgery weight-bearing is often restricted for 8-12 weeks to avoid secondary fixation failure. However, non- or restricted weight-bearing commonly results in atrophy, and older patients are at additional risk of long-term mobility and functionality loss. Therefore, if the risk of secondary fracture failure proves to be lower than currently believed, early or permissive weight-bearing might actually be the preferred treatment choice to advance fracture healing and decrease recovery time. This study aims to review the current literature on early weight-bearing outcomes of acetabular fractures in older adults.

A systematic search of two databases was conducted following PRISMA guidelines. Eligible studies reported on early weight-bearing outcomes of older patients after surgical management. Data were showed in tables alongside a narrative synthesis. Critical appraisal and risk-of-bias tools assessed the study quality.

Six studies were included with a retrospective or observational design, with a total of 147 patients averaging 64 years old. The majority of studies discussed early weight-bearing protocols after percutaneous fixation (PF), with heterogeneity in terminology across protocols.

Albeit limited and low in evidence, the included studies suggest that early weight-bearing might be a possible alternative for non- or minimally displaced fractures and displaced fractures after PF and open reduction internal fixation, respectively. When risk assessments and functional outcomes are appropriately investigated, early weight-bearing may help patients, especially older adults, avoid suffering and prolonged rehabilitation periods.
