Greater length of hospital stay for concurrent hip and upper limb fractures compared to isolated hip fractures: a systematic review of 13 studies including 210,289 patients and meta-analysis

BackgroundThe impact of concurrent upper limb and fragility hip fractures has not been well defined. A greater understanding of this can guide decision making in the early peri-operative period and subsequent rehabilitation of such patients.AimsTo identify if patients with concurrent upper limb and fragility hip fractures have different outcomes and demographics than those with an isolated hip fracture.MethodsA search of MEDLINE and EMBASE was performed to identify cohort and case-control studies, comparing concurrent hip and upper limb fractures with isolated hip fractures. Meta-analysis was conducted using RevMan 5.4. Subgroup analyses were performed for concurrent distal radius and concurrent proximal humerus fractures.Results13 studies were included reporting on 196,916 patients with an isolated hip fracture and 13,373 with concurrent hip and upper limb fractures. Patients with concurrent upper limb fractures had a significantly longer length of hospital stay (mean difference: 3.97 days, 95% CI: 1.36, 6.57, P=0.003) as compared to those with isolated hip fractures. Patients with concurrent upper limb fractures were significantly more likely to be female (OR: 0.57, 95% CI: 0.46, 0.70, P<0.00001), reside at home pre-injury (OR: 0.6, 95% CI: 0.37, 0.96, P=0.03) and have no cognitive impairment (OR: 0.54, 95% CI: 0.35, 0.84, P=0.006). Patients with concurrent distal radius fractures had significantly lower 90-day mortality (OR: 0.70, 95% CI: 0.49, 0.99, P=0.04) and 1-year mortality (OR: 0.68, 95% CI: 0.51, 0.90, P=0.008).ConclusionsConcurrent fragility hip and upper limb fractures are associated with increased length of hospital stay. We recommend early, aggressive, individualised rehabilitation to help improve outcomes and early hospital discharge in this highly vulnerable patient group.
