Mortality from tibial shaft fractures in the elderly (MTFE)-a multicentre study of management outcomes

The mortality rate for tibial shaft fractures in the elderly is comparable to that of hip fractures, yet there is considerable variation in their management. Operative treatment allows for earlier weight-bearing and reduces potential complications of prolonged immobilization; however, it carries risks for this comorbid cohort. The main objective of this study was to assess the difference in 1-year mortality between operative and non-operative management.

A multicentre study was conducted across six trusts in England, including eight acute hospitals: three major trauma centres and five district general hospitals (DGHs). Data were collected retrospectively, covering a 5-year period from January 2017 to December 2021. The study included all patients aged 65 and over with diaphyseal tibial fractures (AO42). Patients with non-acute (>3 weeks), periprosthetic, pathological, or multiple lower limb fractures were excluded.

A total of 171 patients were identified, comprising 38 % males and 62 % females. Of these, 59.6 % were managed operatively, while 40.4 % were managed non-operatively. The median length of stay was similar between groups (8 days non-operative vs. 8.5 days operative, p = 0.87). Non-union (21.7 % vs. 6.3 %, p < 0.001) and malunion rates (27.7 % vs. 4.6 %, p = 0.001) were significantly higher in the non-operative group. One-year mortality was also higher in the non-operative group (38.3 % vs. 12.1 %, p < 0.001). Univariate and multivariate analyses showed an odds ratio of 4.5 and 4.7 for one-year mortality with non-operative treatment, with p-values of <0.001 and 0.005, respectively.

This study demonstrated that non-operatively treated tibial shaft fractures in the elderly are associated with significantly higher rates of non-union, malunion, and 1-year mortality. Therefore, we recommend an expedited multi-disciplinary approach to managing these patients, including surgical treatment and unrestricted weight bearing where possible, to optimize outcomes.
