Abstract

BACKGROUND

Ankle fractures are one of the most commonly occurring fractures in the elderly population. The overall incidence has been reported to be up to 184 fractures per 100,000 persons per year, of which 20-30% occur in the elderly. Medical co-morbidities, osteoporosis, suboptimal skin quality and poor toleration of non-weight bearing status all contribute to difficulties in managing these injuries in this population. Intramedullary implants are advantageous as they utilise smaller incisions, minimise soft tissue disruption and may allow early weight bearing. This systematic review aims to analyse the use of both fibula nails and talo-tibial-calcaneal (TTC) implants in the management of fragility ankle fractures.

METHODS

We conducted a systematic review of the literature using the online databases Medline and EMBASE on 26th December 2015. Only studies assessing ankle fractures that were treated with either an intramedullary fibula nail or TTC implant were included. Studies must have reported complications, patient mobility status or a functional outcome measure. Studies were excluded if the intramedullary device utilised was an adjunct to plate fixation or where a variety of surgical treatments were included in the study. The included studies were appraised with respect to a validated quality assessment scale.

RESULTS

Our search strategy produced 350 studies although only 17 studies met inclusion criteria; ten assessed a fibula nail and seven assessed a standard hindfoot nail, a TTC implant. 15 studies were case series, the overall quality of the studies was low and only one randomised controlled trial was reviewed. The mean Olerud and Molander Ankle Score for fibula nail studies ranged from 58 to 97 and the complication rate from 0 to 22%. Two comparative studies reported a statistically significant increase in complication rate with plate fixation but similar functional outcomes. Studies assessing TTC implants reported a mean Olerud and Molander Ankle Score of 50-62 and complication rate from 18 to 22.6%.

CONCLUSION

The studies reviewed suggest that fibula nails may be capable of producing similar functional outcomes with lower rates of complications to plate fixation. TTC implants produce lower functional outcomes but this may be acceptable in a subgroup of patients at high risk or with reduced pre-injury mobility. However, the low quality of evidence reviewed, the variation in patients included, implant used and outcome scores measured restricts the ability to draw definitive conclusions. Further comparative studies are required to explore the role of these implants further.
