RESUMEN
The purpose of this narrative review of the recent literature is to analyze the outcomes, complications, and implant survival of total knee arthroplasty (TKA) carried out on people with hemophilia (PWH). It has been shown that TKA substantially alleviates preoperative pain and improves knee function and the patient's quality of life. However, the complication rates of TKA range between 8.5% and 28.7, with postoperative hemarthrosis being the most frequent (7.6%). Besides, when comparing if the TKA was implanted before or after the year 2000, a reduction was found in the rates of periprosthetic joint infection-PJI (6.2% to 3.9%) and aseptic loosening (3.8% to 2.1%). Comparing prosthesis survival between PWH who had suffered early postoperative bleeding complications (EPBC) and patients who did not suffer EBPC, the mean survival duration was 17 years for the EPBC group and 22.1 years for the non-EPBC group. Survival rates were 80% for the EPBC group and 96.4% for the non-EPBC group. Compared to patients without hemophilia, PWH had a substantially higher incidence of PJI (Odds Ratio-OR 1.6) and 1-year revision/re-operation (OR 1.4). In short, although TKA substantially improves the quality of life of PWH, it is an intervention that has a non-negligible percentage of complications. TKA in PWH should preferably be performed only in highly specialized centers for the orthopedic treatment of hemophilia.
RESUMEN
Ossiculoplasty is a surgical operation performed to restore auditory transmission through the reconstruction of the ossicular chain using prosthetics. Tissue bioengineering has assumed a pivotal role in implementing alternatives to conventional ossicular middle ear replacement prostheses, to overcome extrusion while preserving acoustic properties. This in vitro study aims to explore, for the first time in current literature, the feasibility of a biohybrid middle ear prosthesis, composed of titanium surrounded by a bone extracellular matrix as bio-coating. We have hereby studied the adhesion and proliferation of human adipose-derived mesenchymal stem cells (hASC) on titanium scaffolds in vitro. Moreover, we identified the osteogenic differentiation of hASC using an immunofluorescence assay to analyze osteoblasts' gene expression profiles (Alp, Runx2, Col1a1, Osx, and Bglap), and we counted the presence of collagen as a marker of hASC's ability to secrete an extracellular matrix. We utilized scanning electron microscopy to evaluate the presence of an extracellular matrix on the scaffolds. Our preliminary data demonstrated the titanium's ability to support human adipose-derived mesenchymal stem cell colonization, proliferation, and osteoblastic differentiation, in order to obtain a biohybrid device. Our experience seems encouraging; thus, we advocate for further in vivo research to corroborate our results regarding bone transplantation.
RESUMEN
Titanium middle ear (ME) prostheses are widely used in surgical practice due to their acoustic properties. However, they present a significant drawback shared by all synthetic materials currently in use for ME reconstruction: they can be rejected by the organism of the host. In this study, we aim to review the current literature on titanium partial ossicular replacement prostheses (PORPs) and total ossicular replacement prostheses (TORPs) extrusion and dislocation. Eighty articles were analysed after a full article review based on the inclusion and exclusion criteria. The most common indication for reconstruction was chronic otitis media with cholesteatoma. The average extrusion or dislocation rate was 5.2%, ranging from 0 to 35%. The average improvements in the air-bone gap were 12.1 dB (1.6 dB to 25.1 dB) and 13.8 (-0.5 dB to 22.7 dB) for the PORP and TORP groups, respectively. The data reported on this topic are highly variable, demonstrating that functional outcomes are difficult to predict in clinical practice. We believe that the current limitations could be overcome with technological developments, including bioengineering research focused on promoting prosthesis adaptation to the ME environment.
RESUMEN
BACKGROUND: Ehlers-Danlos syndrome (EDS) is a phenotypically and genetically heterogeneous group of connective tissue disorders. Currently, diagnosis of EDS is based on a series of clinical and genetic tools. On the other hand, the hypermobile form has not yet been characterized from a genetic point of view: it is considered a part of a continuous spectrum of phenotypes, ranging from isolated non syndromic joint hypermobility, through to the recently defined hypermobility spectrum disorders (HSD). The aim of this study is to characterize the pain symptom that is not considered among the diagnostic criteria but is relevant to what concerns the quality of life of patients with EDS. (2) Methods: A review of the literature was performed on two medical electronic databases (PubMed and Embase) on 20 December 2022. Study selection and data extraction were achieved independently by two authors and the following inclusion criteria were determined a priori: published in the English language and published between 2000 and 2022. (3) Results: There were fifty eligible studies obtained at the end of the search and screen process. Pain is one of the most common symptoms found in Ehlers-Danlos (ED) patients. Different causes seem to be recognized in different phases of the syndrome. (4) Conclusions: Pain is a nonspecific symptom and cannot be considered among the diagnostic criteria, but it is a negative predictive factor in the quality of life of patients with EDS. Therefore, proper evaluation and treatment is mandatory.
RESUMEN
Low-level laser therapy (LLLT) is a treatment that is increasingly used in orthopedics practices. In vivo and in vitro studies have shown that low-level laser therapy (LLLT) promotes angiogenesis, fracture healing and osteogenic differentiation of stem cells. However, the underlying mechanisms during bone formation remain largely unknown. Factors such as wavelength, energy density, irradiation and frequency of LLLT can influence the cellular mechanisms. Moreover, the effects of LLLT are different according to cell types treated. This review aims to summarize the current knowledge of the molecular pathways activated by LLLT and its effects on the bone healing process. A better understanding of the cellular mechanisms activated by LLLT can improve its clinical application.

Bone responses to pulsed electromagnetic fields (PEMFs) have been extensively studied by using devices that expose bone cells to PEMFs to stimulate extracellular matrix (ECM) synthesis for bone and cartilage repair. The aim of this work was to highlight in which bone healing phase PEMFs exert their action. Specifically, we evaluated the effects of PEMFs both on human adipose mesenchymal stem cells (hASCs) and on primary human osteoblasts (hOBs) by testing gene and protein expression of early bone markers (on hASCs) and the synthesis of late bone-specific proteins (on hOBs) as markers of bone remodeling. Our results indicate that PEMFs seem to exert their action on bone formation, acting on osteogenic precursors (hASCs) and inducing the commitment towards the differentiation pathways, unlike mature and terminally differentiated cells (hOBs), which are known to resist homeostasis perturbation more and seem to be much less responsive than mesenchymal stem cells. Understanding the role of PEMFs on bone regenerative processes provides important details for their clinical application.

Background: IM nails are the gold standard of subtrochanteric fractures management. Indications to use a short rather than a long nail remain unclear. Operative complications of subtrochanteric fractures reach up to 25%. Objective: Retrospectively compare clinical and radiographic outcome of subtrochanteric fractures treated by long and short intramedullary nailing, analysing rates of complications. Methods: 390 patients were chosen from the archives. 194 patients were available: 70 treated with a short intramedullary nail (Group A), while 124 with long one (Group B). Radiographic evaluation at 6 and 12 months assess failure of the osteosynthesis. Clinical outcomes were the return to normal activities prior trauma and VAS scale. Group A mean age was 81.37 years, group B mean age was 78.9 years (29-99, SD: 15.38). Results: Radiografic Healing was found in 66 patients (94.28%) in group A, while in 116 patients (94.54%) in group B. Pseudarthrosis was found in 4 cases (5.71%) in group A, while in 8 cases (6.45%) in group B. Implant failure occurred in 5 cases: one required revision of fixation, while 4 require hip replacement. 59 patients of group A (84.29%) returned to social life, while 102 patients (81.94%) in group B. Group A mean VAS was 1.55, Group B mean VAS was 1.49. Conclusion: Comparison of the two group showed no differences. Complication percentages are in line with literature. Optimal reduction and fixation allow high percentage of healing and return to social life.
RESUMEN
An emerging issue for orthopedic surgeons is how to manage patients with active or previous COVID-19 disease, avoiding any major risks for the surgeons and the O.R. personnel. This monocentric prospective observational study aims to assess the prevalence of SARS-CoV-2 viral RT-PCR RNA in cancellous bone samples in patients with active or previous COVID-19 disease. We collected data about 30 consecutive patients from our institution from January 2021 to March 2021 with active or previous COVID-19 disease. The presence of SARS-CoV-2 in the samples was determined using two different PCR-based assays. Eighteen of the thirty patients included in the study had a positive nasopharyngeal swab at the time of surgery. Twelve patients had a negative nasopharyngeal swab with a mean days since negativization of 138 ± 104 days, ranging from 23 to 331 days. Mean days of positivity to the nasal swab were 17 ± 17. Twenty-nine out of thirty (96.7%) samples were negative for the presence of SARS-CoV-2 RNA. In one sample, low SARS-CoV-2 load (Cycle threshold (Ct) 36.6.) was detected but not confirmed using an additional confirmatory assay. The conducted study demonstrates the absence of the viral genome within the analyzed cancellous bone. We think that the use of personal protection equipment (PPE) to only protect from aerosol produced during surgery, both in active and recovered patients, is not strictly necessary. We think that the use of PPE should not be employed by surgeons and the O.R. personnel to protect themselves from aerosols produced from the respiratory tract. Moreover, we think that our results could represent a valid basis for further studies related to the possibility of bone donation in patients that suffered and recovered from COVID-19.

BACKGROUND: the incidence of Achilles tendon (AT) rupture is rising; however, there is no clear consensus regarding the optimal treatment. The aim of this retrospective study was to compare instrumental and patient-reported outcome scores after fast functional rehabilitation (group A) versus plaster cast immobilization (group B) programs in patients who underwent AT tenorrhaphy. METHODS: 33 patients, with similar clinical and demographic features, underwent open AT tenorrhaphy between January and July 2018. Of these, 15 patients were treated with fast functional rehabilitation program (group A), and 18 patients were treated with plaster cast immobilization protocol (group B). Sural triceps hypotrophy and functional scores (American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score, and Achilles tendon Total Rupture Score (ATRS)) were recorded at a 12-month follow-up. Ultrasonography (US) and elastosonography (ES) were used to compare the characteristics of the tendons after surgery. RESULTS: At 12 months, no significant differences in any of the patient-reported outcomes or the instrumental measurement tests were seen between the two groups. CONCLUSIONS: fast functional rehabilitation after AT surgical repair is safe, effective, and may be the first choice of treatment, especially in young, collaborative, and active patients.
RESUMEN
BACKGROUND: Musculoskeletal disorders (MSKDs) are the most common class of complaints among patients presenting for care in the Emergency Department (ED). There is a non-urgent patient population with musculoskeletal complaints attending ED services that creates a burgeoning waiting list and contributes to overcrowding in Emergency Departments (EDs), which is a major concern worldwide. The recent (Coronavirus disease-19) COVID-19 pandemic is an unprecedented challenge that is revealing the structural and situational strengths and weaknesses of healthcare systems. METHODS: This study retrospectively and prospectively assessed patients presenting to the Emergency Department before and after the COVID-19 outbreak (from 21 February 2019 to 3 May 2019 and from 21 February 2020 to 3 May 2020) with non-traumatic or low-severity musculoskeletal conditions to test the hypothesis that these patients should have access to care outside the ED and that the COVID-19 outbreak has changed patients' care and health perception. RESULTS: A total of 613 patients were identified, and 542 of them (87.56%) participated in a personalized survey. From this number, 81.73% of the total accesses took place in 2019, and only 18.27% of the accesses took place during the first outbreak and lockdown. More than 90% of patients admitted to the ED accessed care during the day shift in both periods. A total of 87.30% of patients presenting to the ED with a MSKD followed their general practitioner's (GP) advice/referral in 2019, and 73.87% did so in 2020. The differences in the means of transport to the ED was statistically significant (p-value 0.002). CONCLUSIONS: The outbreak and lockdown period confirmed that there is an inappropriate use of the ED related to patients with MSKD. However, the ED appears to be the only available solution for these patients. New services and pathways are therefore needed to enhance MSKD management and reduce ED crowding. Additional observational studies shall be developed to confirm and compare our findings with those of various EDs. The main limit of the inferential part of the study is probably due to the small sample of patients in 2020.

BACKGROUND: Ehlers-Danlos syndromes (EDS) have been associated with psychological distress, comorbid psychiatric disorders, and worsening in quality of life (QoL). Among the neurodevelopmental disorders, autism spectrum disorders (ASD) have shown the highest rates of co-occurrence with EDS. The reasons for these associations are unknown and a possible role of pain in increasing the risk of psychiatric disorders in EDS has been suggested. However, a detailed picture of an Italian EDS sample is still lacking. METHODS: We conducted a web-based survey in a third level center for the diagnosis of EDS in northern Italy, to investigate psychological distress, QoL, and the presence of autistic traits. Furthermore, we correlated the psychometric data with some clinical variables. RESULTS: We observed a high rate of psychological distress with 91% of the responders at high risk of common mental disorders, low QoL, and high prevalence of autistic traits in EDS patients. Specifically, patients lacking a specific genetic test, diagnosed as suspects of EDS appeared to be at greater risk and reported worse psychological QoL. Pain was significantly associated with both psychological distress and worse QoL. CONCLUSIONS: Our findings support the need of further research and of a multi-disciplinary approach to EDS including psychological and psychiatric liaison.
RESUMEN
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.

BACKGROUND: Haemophilia is an inherited coagulopathy caused by the absence or dysfunction of clotting factor VIII or IX. Clinical manifestations are generally secondary to recurrent bleeding episodes mainly in the musculoskeletal system. Bleeding symptoms appear early in life and, when the disease is severe (when plasma factor VIII or IX activity is <1% of normal), joint and muscle bleeding may occur spontaneously. A pseudotumour is a recurrent, chronic, encapsulated, slowly expanding, muscle hematoma. Haemophilic pseudotumour is a rare complication of haemophilia which occurs, as a condition either from repeated spontaneous bleeding or coming from a traumatic origin, in 1-2% of haemophilic patients. CASE REPORT: A 32-year-old man with severe haemophilia A referred to our Clinic with a massive right iliac wing pseudotumour complicated by Staphylococcus aureus superinfection and skin fistulisation. In this report we describe the medical management and surgical treatment by the adoption of a novel surgical technique which involves the use of a pedicle-screw and rod system (PSRS), a polyglycolic acid MESH and bone cement in order to build up an artificial ilium-like bony mass. This case report highlights the importance of interdisciplinary approach and the efficacy of eradicating surgery as treatment, especially in the case of large and long-lasting lesions.
RESUMEN
Ehlers-Danlos syndromes (EDS) are an inherited heterogeneous group of connective tissue disorders characterized by an abnormal collagen synthesis affecting skin, ligaments, joints, blood vessels, and other organs. It is one of the oldest known causes of bruising and bleeding, and it was described first by Hippocrates in 400 BC. In the last years, multiple gene variants involved in the pathogenesis of specific EDS subtypes have been identified; moreover, new clinical diagnostic criteria have been established. New classification models have also been studied in order to differentiate overlapping conditions. Moreover, EDS shares many characteristics with other similar disorders. Although distinguishing between these seemingly identical conditions is difficult, it is essential in ensuring proper patient care. Currently, there are many genetic and molecular studies underway to clarify the etiology of some variants of EDS. However, the genetic basis of the hypermobile type of EDS (hEDS) is still unknown. In this review, we focused on the study of two of the most common forms of EDS-classic and hypermobile-by trying to identify possible biomarkers that could be of great help to confirm patients' diagnosis and their follow up.

In this article, we provide an extensive review of the recent literature of the signaling pathways modulated by Pulsed Electromagnetic Fields (PEMFs) and PEMFs clinical application. A review of the literature was performed on two medical electronic databases (PubMed and Embase) from 3 to 5 March 2021. Three authors performed the evaluation of the studies and the data extraction. All studies for this review were selected following these inclusion criteria: studies written in English, studies available in full text and studies published in peer-reviewed journal. Molecular biology, identifying cell membrane receptors and pathways involved in bone healing, and studying PEMFs target of action are giving a solid basis for clinical applications of PEMFs. However, further biology studies and clinical trials with clear and standardized parameters (intensity, frequency, dose, duration, type of coil) are required to clarify the precise dose-response relationship and to understand the real applications in clinical practice of PEMFs.

INTRODUCTION: Congenital dislocation of the patella (CDP) is a rare condition and its treatment is not well defined. In CDP, patella is dislocated on the lateral aspect of the distal femur, laterally from the trochlear groove, it cannot be reduced manually and it is almost always associated with genu valgum, lateral torsion of the proximal tibia, and flexion contracture of the knee. This condition is present at birth, but the clinical findings can be subtle at birth due to the size and character of the structures being examined; early diagnosis is essential, but it may be delayed to late childhood or adulthood. If CDP is not promptly treated, the disability increases during growth, so surgical correction should be planned as soon as the diagnosis is confirmed. CASE REPORT: We report a case of bilateral CDP associated with bilateral proximal radioulnar joint stiffness; the patient at the age of diagnosis was 11 years old and underwent a bilateral delayed surgical procedure; the 4-year follow-up results are satisfactory. Surgical treatment rationale and literature are reviewed. CONCLUSION: Surgical correction for CDP is generally recommended, but there is no agreement in literature on the ideal treatment and in some cases, with mild impairment of the knee function, observation alone has been suggested. The decision about a surgical treatment can be difficult and depends on the degree of disability of the patient.
RESUMEN
BACKGROUND: Hip fracture is one of the most common orthopedic causes of hospital admission in frail elderly patients. Hip fracture fixation in this class of patients is considered a high-risk procedure. Preoperative physical examination, plasma natriuretic peptide levels (BNP, Pro-BNP), and cardiovascular scoring systems (ASA-PS, RCRI, NSQIP-MICA) have all been demonstrated to underestimate the risk of postoperative complications. We designed a prospective multicenter observational study to assess whether preoperative lung ultrasound examination can predict better postoperative events thanks to the additional information they provide in the form of "indirect" and "direct" cardiac and pulmonary lung ultrasound signs. METHODS: LUSHIP is an Italian multicenter prospective observational study. Patients will be recruited on a nation-wide scale in the 12 participating centers. Patients aged > 65 years undergoing spinal anesthesia for hip fracture fixation will be enrolled. A lung ultrasound score (LUS) will be generated based on the examination of six areas of each lung and ascribing to each area one of the four recognized aeration patterns-each of which is assigned a subscore of 0, 1, 2, or 3. Thus, the total score will have the potential to range from a minimum of 0 to a maximum of 36. The association between 30-day postoperative complications of cardiac and/or pulmonary origin and the overall mortality will be studied. Considering the fact that cardiac complications in patients undergoing hip surgery occur in approx. 30% of cases, to achieve 80% statistical power, we will need a sample size of 877 patients considering a relative risk of 1.5. CONCLUSIONS: Lung ultrasound (LU), as a tool within the anesthesiologist's armamentarium, is becoming increasingly widespread, and its use in the preoperative setting is also starting to become more common. Should the study demonstrate the ability of LU to predict postoperative cardiac and pulmonary complications in hip fracture patients, a randomized clinical trial will be designed with the scope of improving patient outcome. Trial registration ClinicalTrials.gov, NCT04074876. Registered on August 30, 2019.
RESUMEN
INTRODUCTION: Bone metastases are frequent in patients with cancer. Electrochemotherapy (ECT) is a minimally invasive treatment. Preclinical and clinical studies supported the use of ECT in patients with metastatic bone disease (MBD). The purposes of this multicentre study are to confirm the safety and efficacy of ECT, and to identify appropriate operating procedures in different MBD conditions. MATERIALS AND METHODS: 102 patients were treated in 11 Centres and recorded in the REINBONE registry (a shared database protected by security passwords): clinical and radiological information, ECT session, adverse events, response, quality of life indicators and duration of follow-up were registered. RESULTS: 105 ECT sessions were performed (one ECT session in 99 patients, two ECT sessions in 3 patients). 24 patients (23.5%) received a programmed intramedullary nail after ECT, during the same surgical procedure. Mean follow-up was 5.9 ± 5.1 months (range 1.5-52). The response to treatment by RECIST criteria was 40.4% objective responses, 50.6% stable disease and 9% progressive disease. According to PERCIST criteria the response was: 31.4% OR; 51.7% SD, 16.9% PD with no significant differences between the 2 criteria. Diagnosis of breast cancer and ECOG values 0-1 were significantly associated to objective response. A significant decrease in pain intensity and significant better quality of life was observed after ECT session at follow-up. CONCLUSION: The results are encouraging on pain and tumour local control. ECT proved to be an effective and safe treatment for MBD and it should be considered as an alternative treatment as well as in combination with radiation therapy.

BACKGROUND: Periprosthetic fractures (PPFs) are a growing matter for orthopaedic surgeons, and patients with PPFs may represent a frail target in the case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The purpose of this study is to investigate whether hospital reorganisations during the most severe phase of the SARS-CoV-2 pandemic affected standards of care and early outcomes of patients treated for PPFs in Northern Italy. MATERIALS AND METHODS: Data were retrieved from a multicentre retrospective orthopaedics and traumatology database, including 14 hospitals. The following parameters were studied: demographics, results of nasopharyngeal swabs, prevalence of coronavirus disease 2019 (COVID-19), comorbidities, general health status (EQ-5D-5L Score), frailty (Clinical Frailty Scale, CFS), pain (visual analogue scale, VAS), anaesthesiologic risk (American Society of Anaesthesiology Score, ASA Score), classification (unified classification system, UCS), type of operation and anaesthesia, in-hospital and early complications (Clavien-Dindo Classification, CDC), and length of stay (LOS). Data were analysed by means of descriptive statistics. Out of 1390 patients treated for any reason, 38 PPFs were included. RESULTS: Median age was 81 years (range 70-96 years). Twenty-three patients (60.5%) were swabbed on admission, and two of them (5.3%) tested positive; in three patients (7.9%), the diagnosis of COVID-19 was established on a clinical and radiological basis. Two more patients tested positive post-operatively, and one of them died due to COVID-19. Thirty-three patients (86.8%) presented a proximal femoral PPF. Median ASA Score was 3 (range, 1-4), median VAS score on admission was 3 (range, 0-6), median CFS was 4 (range, 1-8), median EQ-5D-5L Score was 3 in each one of the categories (range, 1-5). Twenty-three patients (60.5%) developed post-operative complications, and median CDC grade was 3 (range, 1-5). The median LOS was 12.8 days (range 2-36 days), and 21 patients (55.3%) were discharged home. CONCLUSIONS: The incidence of PPFs did not seem to change during the lockdown. Patients were mainly elderly with comorbidities, and complications were frequently recorded post-operatively. Despite the difficult period for the healthcare system, hospitals were able to provide effective conventional surgical treatments for PPFs, which were not negatively influenced by the reorganisation. Continued efforts are required to optimise the treatment of these frail patients in the period of the pandemic, minimising the risk of contamination, and to limit the incidence of PPFs in the future.

BACKGROUND: Treatment of hip fractures during the coronavirus disease 2019 (COVID-19) pandemic has posed unique challenges for the management of COVID-19-infected patients and the maintenance of standards of care. The primary endpoint of this study is to compare the mortality rate at 1 month after surgery in symptomatic COVID-positive patients with that of asymptomatic patients. A secondary endpoint of the study is to evaluate, in the two groups of patients, mortality at 1 month on the basis of type of fracture and type of surgical treatment. MATERIALS AND METHODS: For this retrospective multicentre study, we reviewed the medical records of patients hospitalised for proximal femur fracture at 14 hospitals in Northern Italy. Two groups were formed: COVID-19-positive patients (C+ group) presented symptoms, had a positive swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and received treatment for COVID-19; COVID-19-negative patients (C- group) were asymptomatic and tested negative for SARS-CoV-2. The two groups were compared for differences in time to surgery, survival rate and complications rate. The follow-up period was 1 month. RESULTS: Of the 1390 patients admitted for acute care for any reason, 477 had a proximal femur fracture; 53 were C+ but only 12/53 were diagnosed as such at admission. The mean age was > 80 years, and the mean American Society of Anesthesiologists (ASA) score was 3 in both groups. There was no substantial difference in time to surgery (on average, 2.3 days for the C+ group and 2.8 for the C- group). As expected, a higher mortality rate was recorded for the C+ group but not associated with the type of hip fracture or treatment. No correlation was found between early treatment (< 48 h to surgery) and better outcome in the C+ group. CONCLUSIONS: Hip fracture in COVID-19-positive patients accounted for 11% of the total. On average, the time to surgery was > 48 h, which reflects the difficulty of maintaining normal workflow during a medical emergency such as the present pandemic and notwithstanding the suspension of non-urgent procedures. Hip fracture was associated with a higher 30-day mortality rate in COVID-19-positive patients than in COVID-19-negative patients.
