<p class="abstract"><strong>Background:</strong> Ankle fractures have been identified as a significant source of morbidity for both the young and the elderly. In this study we aim to evaluate the functional outcome of patients who were operated for ankle fracture at our centre and to assess the factors associated with the functional outcome.</p><p class="abstract"><strong>Methods:</strong> An observational study in the Department of Orthopedics, AJ Institute of Medical Sciences, Mangalore, Karnataka from January 1, 2017 till December 31, 2017 of all patients who presented with any type of ankle malleolar fracture and underwent surgery were included in the study. Clinical history, socio-demographic profile, anatomic classification and Weber’s classification was noted for all patients.

Supination external rotation was the most commonly seen injury in our patient population. Postoperatively, superficial skin infections were seen in 15% and restricted ankle movement in 11% patients. According to the Baird and Jackson score, clinical functional outcome was excellent in 17 cases, good in 47, fair in 15 and poor in 5 patients. Patients aged less than 45 years and supination external rotation injuries were significantly associated with excellent and good functional outcomes as compared to patients of older age.</p><p><strong>Conclusions:</strong> Surgical treatment resulted in excellent to good functional outcome in majority of the patients of this study.

Ankle fractures are common representing up to 10% of all fractures with an incidence that is rising. Both conservative treatment and operative management of ankle fractures can lead to excellent outcomes. Neurovascular injuries are uncommon but can be a source of significant morbidity and associated poor outcome. The superficial peroneal nerve (SPN) in the lateral approach and the sural nerve in the posterolateral approach are at risk of injury. We report an unexpected finding of a superficial peroneal nerve incarcerated in the fibular fracture site of pronation external rotation type/ Weber-C ankle fracture. To the best of our knowledge we believe this to be the first English language report of an incarcerated SPN at a fibular ankle fracture site.

The two dominant classification systems for ankle fractures in use are the Lauge-Hansen and AO-Danis-Weber schemes. Each has certain advantages and disadvantages. Because of basic similarities, integration of these systems into one scheme involving three basic patterns with appropriate staging appears to be reasonable. This integration is based upon combining the pronation-abduction and pronation-external rotation injuries in Lauge-Hansen's scheme into one pronation-abduction-external rotation pattern. The resultant system would appear attractive in terms of combining relative simplicity with completeness.

Category: Trauma Introduction/Purpose: The genetic Lauge-Hansen classification is considered to provide a link between mechanism of ankle injury and resulting fracture morphology. In this study, we addressed the question of agreement between the mechanism of the fracture as postulated by the Lauge-Hansen classification and mechanism reported by the patient in rotational ankle fractures. Understanding of the actual mechanisms of ankle fracture may guide treatment decisions. Methods: Of 110 screened patients with acute malleolar fractures, 78 were able to provide information on their fracture mechanism and were included in the study. The study group consisted of 43 women and 35 men with a mean age of 47.8 (range 19.5-88.4) years. Patients were asked to describe the direction of deformation with primary question being pronation and supination as demonstrated by the examiner. As hyperplantarflexion and hyperdorsiflexion has been spontaneously reported by the patients, these directions were added to the analysis. Radiographs were analyzed according to Lauge-Hansen classification and compared with fracture mechanisms reported by the patients. Results: The majority (35/78 = 44.8%) of patients reported pronation as their fracture mechanism, 27 (34.6%) patients reported supination, 15 (19.2%) patients reported hyperplantarflexion (3 pure, one combined with pronation and 11 combined with supination), and 1 patient reported hyperdorsiflexion combined with pronation. Radiographs revealed 61 supination-external rotation (79%), 1 supination-adduction (1.3%), 14 pronation-external rotation (18%), 1 pronation-abduction (1.3%) fractures. One x-ray was unclassifiable with the Lauge-Hansen classification. The patient reported mechanisms were in concordance with the mechanism deducted from the x-rays in 49% of cases. Only 17% of patients who recalled a pronation trauma actually had radiographs classified as pronation fractures while 76% of patients who recalled a supination trauma were also radiographically classified as having sustained supination type fractures. Conclusion: The Lauge-Hansen classification should be used with caution for determining the actual mechanism of injury as it was able to predict the patient reported fracture mechanism in less than 50% of cases. A substantial percentage of fractures appearing radiographically as supination type injuries may have been actually produced by a pronation fracture mechanism.
