A total of 96 displaced tibial plateau fractures in 94 patients (average age, 48 years) were treated with open reduction and internal fixation. At 12 months postoperatively, mean range of knee motion was 126 degrees and 10 (10%) of the patients had required a secondary surgery. Using a binary regression model, no demographic variable such as age, gender, smoking history, diabetes, BMI; or fracture characteristic such as mechanism of injury, initial plateau depression, Schatzker classification was identified that correlated with short-term functional outcome such as a complication, range of motion, healing time, or residual depression. We determined that radiographic fracture reduction was not superior following fractures with less initial displacement, and increased plateau collapse at 12 months postoperatively was not indicative of decreased function. However, an increased postoperative articular step-off was found to be associated with an increased risk of plateau collapse (p < 0.01). Furthermore, at 12 months, 76% of the patients had returned to their preinjury employment and the overall complication rate was 13%.
In 2009, 36.9 million people living in the USA were over the age of 65 years. It is speculated that by the year 2030, that number will jump to 72.1 million. The increased physical demand of the aging American population has been accompanied by an amplification in the number and severity of ankle and foot fractures in the elderly. This article reviews the various issues associated with ankle and foot fractures in this potentially complex patient population, focusing on risk factors for fracture and the continued debate over surgical versus nonsurgical management. The higher level of activity of the aging American population has significantly increased the incidence of ankle and foot fractures in the elderly. Although certain authors have suggested that osteoporosis is the single strongest risk factor for both foot and ankle fractures, it appears that lifestyle factors such as an increased BMI and a propensity for falling play a larger role in ankle fractures, while foot fractures are more typical fragility fractures. Caused by the prevalence of medical comorbidities in older patients, controversy exists over the optimal management of these fractures. While early investigators cited unacceptable postoperative complication rates and poor outcome following surgical management, more recent studies have demonstrated superior outcome following operative treatment. These authors agree that chronological age should not dictate the management of foot and ankle fractures, but rather level of functional activity and the presence of co-morbid medical conditions. Based on current evidence, the literature supports the surgical treatment of displaced ankle, calcaneus, metatarsal, talus and Lisfranc fractures in geriatric patients who are surgical candidates.
The purpose of this study is to describe our experience with distal femur nonunions and to report on the functional recovery of patients treated for these injuries. Twenty-two patients with an established distal femur nonunion were identified and followed prospectively. Results were compared with a control group consisting of 18 similar patients who had sustained an acute distal femur fracture. Compared with acute fracture patients, patients with a nonunion were more likely to have had an open fracture at initial injury (p = 0.02) and required a longer time to heal after final surgery (p = 0.054). No demographic variables were found to be predictive of complications, Short Musculoskeletal Functional Assessment scores, or time to union. These results show that patients with a distal femoral nonunion can expect to attain similar ultimate outcomes to patients receiving treatment for an acute distal femur fracture. Unlike the development of nonunions following other types of fracture, such as the hip, distal femur nonunions do not portend poor functional outcomes as long as bone union is achieved.
Background: Bilateral ruptures of the extensor mechanism are rare. Questions/Purpose: The purpose of this study was to compare the clinical outcomes of operatively treated unilateral and bilateral knee soft tissue extensor mechanism injuries and to identify risk factors for bilateral disruption. Methods: All patients operatively treated for a knee extensor mechanism injury were entered into a database and prospectively followed. Postoperative protocol was standardized for all patients. Demographic data, baseline characteristics, range of motion, complications, pain, and functional status were assessed. The main patient-reported outcome measures used in this study were the SF-36 Health Survey and the Lysholm Scale. Results: Patients who sustained bilateral injuries were more likely to have one or more systemic medical conditions. There was no statistical difference between the groups with regard to mechanism of injury or body mass index. The average followup was 29 months (range 6-60 months). Patient-reported outcomes, in the form of the SF-36 Health Survey and Lysholm scores, were not significantly different between the two groups at final follow-up. Range of motion and quadriceps strength was also similar between the two cohorts. At latest follow-up, 88% of patients with unilateral injuries and 83% of patients with bilateral disruption were able to return to their pre-injury employment. Conclusion: Operatively treated bilateral knee extensor mechanism disruptions fare similar to unilateral injuries with regard to ultimate functional outcome. The presence of one of more preexisting medical conditions was identified as a risk factor for bilateral tendinous disruption.
