Effective management of prosthetic joint infection (PJI) requires prolonged, sustained delivery of antibiotics to the effective joint space. Calcium sulphate antibiotic delivery systems have been used in this setting, however, potentially serious complications including symptomatic hypercalcaemia have been described. There is relatively little prospective data on the results with the use of these compounds.

A prospective study was performed between October 2016 and June 2018. 29 patients who underwent revision total hip arthroplasty (THA) for confirmed PJI were treated with Stimulan calcium sulphate antibiotic delivery system. Laboratory blood tests including serum calcium levels, C-reactive protein (CRP) and white cell count (WBC) were monitored for 6 weeks post-surgery. Wounds were assessed for discharge and radiographs for dissolution and for signs of heterotopic ossification.

The mean age was 67 years and mean ASA score III. There was no significant increase between the preoperative serum calcium and those at 2 and 6 weeks. The CRP and white cell count were significantly reduced at 6 weeks. Full dissolution occurred by 6 weeks post-op. 1 patient (3.4%) had a prolonged wound discharge.

Stimulan is a valid option for management of patients with PJI following total hip arthroplasty. Complication rates are low following its use.
