Botulinum toxin A versus platelet rich plasma ultrasound-guided injection in the treatment of plantar fasciitis: A randomised controlled trial.

Background: Platelet-rich plasma (PRP) and botulinum toxin type A (BTX-A) injections have proven effective in clinical trials for plantar fasciitis treatment but have not been directly compared. We aimed to compare clinical outcomes in patients undergoing PRP or BTX-A injections.

Methods: We performed a randomised controlled trial (59 patients; 1-year follow-up) to assess efficacy, using pain and functional scales (VAS, AOFAS Hindfoot-scale and FAAM questionnaire) and fascia thickness reduction, in control and single ultrasound-guided BTX-A or PRP injection groups.

Shoulder arthroplasty. Comorbidity as prognostic factor.

Introduction: Preoperative comorbidity seems to be an important factor for the functional recovery of patients after shoulder replacement, but few studies support this correlation.The purpose of this study was to clinically evaluate the influence of comorbidity in restoring function after shoulder replacement.

Methods: We performed a retrospective analysis of shoulder replacement accomplished at our institution from 2005 to 2016 (n = 70).
