Abstract

Background
This study aimed to investigate nutritional or rehabilitation intervention protocols for hip fracture patients with sarcopenia and to analyze the effect of these protocols through a systematic review of studies that reported clinical results.
Methods
Studies were selected based on the following criteria: (1) study design: randomized controlled trials or non-randomized comparative studies; (2) study population: patients with hip fracture; (3) intervention: nutritional or rehabilitation; and (4) reporting the clinical outcomes and definition of sarcopenia.
Results
Of the 247 references initially identified from the selected databases, 5 randomized controlled studies and 2 comparative studies were selected for further investigation. The total number of patients was 497. We found 2 specific rehabilitation interventions, one medication intervention using erythropoietin, and 4 nutritional interventions using amino-acid or protein. Among the studies included in this systematic review, 2 studies did not find a clear statistical difference in assessment tools compared to controls after intervention. On the other hand, the rest of the studies positively interpreted the results for intervention. The most frequently used assessment tool for intervention was handgrip strength.
Conclusions
Although mainstream methods of intervention for sarcopenia include nutritional, exercise, and drug interventions, the validity of these interventions in elderly hip fractures has not been clearly proven. In addition, as most studies only reported short-term results, there is no consensus on the optimal long-term treatment.
