Abstract

Introduction:

Talar fractures are uncommon injuries, whose outcome is often characterized by the onset of serious complications. The aims of the present study are: 1) to review the available evidence concerning the outcome and complications of talar neck fractures; 2) to describe the clinical results and the rate of post-op complications in a series of patients treated surgically after talar fracture-dislocations.

Materials and methods:

The review of the literature was performed on the Pubmed, Embase and Web of Science databases and aimed at identifying clinical trials with at least 10 patients and dealing with surgical management of talar fracture-dislocation (Hawkins grade II to IV). All the papers were analyzed to extract data concerning common complications such as non-union, mal-union, infection, osteonecrosis and osteoarthtritis. The clinical arm of this paper included 26 patients (19 men and 7 women), who underwent fixation of displaced talar fracture by cannulated screws and were retrospectively evaluated, both clinically and radiographically, at a mean 51.2 ± 23.4 months of follow-up.

Results:

The evaluation through the AOFAS score revelead a loss of functional performance with respect to the pre-injury status. Four patients were re-operated within final follow up, whereas the remaining 22 presented excellent results in 2 cases, good results in 4 cases, fair results in 11 cases and poor results in 5 cases. Osteoarthritis and osteonecrosis incidence were 51.9% and 25.9% respectively. Sixteen studies were included in the review and it was confirmed that the most frequent complication was post-traumatic OA, followed by osteonecrosis and mal-union. A variable range in percentage of complications described should be ascribed to the low quality of trials currently available.

Conclusion:

Displaced talar fracture are challenging to treat and the outcomes at middle-term are often modest. Looking at complications, the present case series and the review of literature revealed that the most common one is peritalar OA. Osteonecrosis, traditionally regarded as the most fearsome adverse event, is relevant but less frequent than OA.

Keywords: Talus, Talar fracture, Osteonecrosis, Osteoarthritis, Complications, Review.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."
