Spontaneous bilateral quadriceps tendon rupture treated with polyethylene terephthalate tape augmentation: Report of two consecutive cases.

Spontaneous rupture of quadriceps tendon (QT) is a rare condition and it is commonly associated with systemic comorbidities and medical products assumption, which may lead to tendon degeneration. While unilateral rupture is a quite common injury, spontaneous bilateral ruptures are very rare. Herein, we report two consecutive cases of spontaneous bilateral QT rupture in two patients with a positive history of chronic statin use, successfully treated with bilateral single-stage reconstruction with polyethylene-terephthalate tape augmentation. At 12 months of follow-up, both patients recovered the full extension, a 120° pain-free flexion and knee scores improvement. Magnetic resonance imaging at one year showed a complete, bilateral, bio-integration of the augmentation for each knee. In conclusion, polyethylene terephthalate tape augmentation provides a good structural support with a good grade of bio-integration, allowing a fast recovery.

The epidemiology of proximal femur fractures during COVID-19 emergency in Italy: a multicentric study.

BACKGROUND AND AIM: After the first Italian case of Covid-19, the Government imposed the complete closure of all areas involved by the spread of the virus to contain transmissions. There was a massive reorganization of Hospitals, a stop of all elective activities and a convertion of many hospitals in "Covid Centers''. AITOG (Associazione Italiana Traumatologia e Ortopedia Geriatrica) conducted a retrospective study on all proximal femur fractures surgeries that occurred in this period, to find out whether the pandemic and the correlated lockdown somehow changed the incidence of these events.  Methods: 10 Italian orthopedic centers were involved in the study. Considering the geographic location, three groups were created (North, Centre and South). The considered period is the Italian "Phase 1" (February 23rd - May 3rd 2020). RESULTS: the cohort is composed of 412 patients, 116 male and 296 female (mean age 81.1 ± 9.1 years). The same period of 2019 has been used as control group, with 558 patients, 156 male and 402 female (mean age 84.2 ± 8.0 years). In 2020 we counted 323 (78.4%) fractures occurred at home, 61 (14.8%) in retirement houses and 28 (6.8%) in different locations. We mainly treated fractures with intramedullary nails (n.237 57.5%). Among all patients we had 46 (11.1%) Covid-19 positive. The mortality rate within 30 days was of 51 patients (12.4%); 23 of these died because of complications related to Covid-19 while 31 of  these were in treatment with anticoagulant/antiaggregant. CONCLUSIONS: AITOG analysis demonstrates a decrease in surgical interventions for proximal femur fractures from 2019 to 2020, a reduction in patients mean age and an increase in trauma occurred in domestic environment. We also registered a consistent difference between the North, Center and South of the Country.

The Impact of Hemodialysis on Mortality and Personal Independence After Hip Fracture. A Prospective Matched Cohort Study.

OBJECTIVE: To determine the cumulative 30-day and 1-year mortality as well as personal independence after hip fracture in patients on hemodialysis. DESIGN: Prospective, observational cohort study with matched controls. SETTING: One teaching hospital, one metropolitan trauma center, one peripheral hospital. PATIENTS AND INTERVENTION: Study group: a consecutive cohort of 64 patients with end-stage renal disease receiving chronic hemodialysis who had undergone surgery for a trochanteric or femoral neck fracture from June 2008 to November 2016. CONTROL GROUP: subjects without end-stage renal disease who underwent surgery for similar hip fractures. MAIN OUTCOME MEASURE: One-year mortality, activities of daily living, and ambulatory activity. RESULTS: The 30-day and 1-year mortality rate in patients with a hip fracture undergoing hemodialysis was 25.0% and 57.8%, respectively. Hemodialysis was independently associated with increased 30-day (Hazard ratio 2.933; 95% confidence interval 1.270-6.770; P = 0.018) and 1-year (hazard ratio 2.535; 95% confidence interval, 1.494-4.299; P < 0.001) mortality compared with the matched controls. At the 1-year follow-up, loss of personal independence in comparison with the prefracture status was detected. CONCLUSIONS: Hemodialysis was associated with increased mortality after hip fracture. A worse prefracture functional status predicted the loss of functional independence at follow-up. LEVEL OF EVIDENCE: Prognostic Level III.
