[Palliative treatment of proximal femur fracture: results of intrathecal phenol (SPING block) in frail older patients].

This case series describes the clinical outcomes of intrathecal phenol (SPING block) as palliative, non-operative treatment of proximal femur fracture (PFF) in frail older patients with comorbidities and pre-morbid limited mobility. The goal of treatment is to provide adequate pain relief. Ten patients (mean age 89.9, SD 6.4 years) were treated with SPING block. Mean pain score (using NRS) decreased from 5.7 at admission to 1.0 within 4-8 hours after treatment, and 0.5 at discharge; without additional analgesics and irrespective of the type of fracture. Mean hospital stay was 1.9 (SD 0.9) days. Only 2 patients experienced side effects after treatment, i.e. temporary hypotensia and fever. Based on this case series, SPING block could be a promising palliative pain treatment in frail older patients with PFF. Further research is necessary to determine the effects of this treatment on quality of life and cost-effectiveness in this increasing group of patients.
