Sickle cell disease (SCD) is an autosomal recessive disorder that is characterized by abnormal “sickle-shaped” erythrocytes. Because of their shape, these erythrocytes are more likely to become trapped in small slow-flowing vessels, leading to vaso-occlusion. Because this commonly happens in the bones, patients with SCD are at an increased risk for orthopaedic manifestations such as osteomyelitis, septic joint, or osteonecrosis. Osteomyelitis is a serious and potentially disabling condition but can be difficult to differentiate from benign conditions of SCD, such as vaso-occlusive crisis. Diagnosis of osteomyelitis requires careful evaluation of the clinical presentation, laboratory testing, and imaging. Treatment of osteomyelitis in patients with SCD may be medical or surgical, but considerations in antibiotic selection and management preoperatively and postoperatively must be taken to ensure optimal outcomes.
Background: Synovial chondromatosis (SC) of the ankle is a rare disorder in which metaplastic proliferation of synovia, tendon sheaths, and/or bursae leads to the formation of loose cartilaginous bodies within the joint space. While SC itself is a benign condition, its sequelae can be chronic and debilitating if left untreated, or if there is postoperative recurrence. Arthritic degeneration and malignant transformation to chondrosarcoma are among the more serious complications in the natural history of the disease; the latter occurs in approximately 5% of cases. We performed a systematic review of the literature on the arthroscopic management of ankle SC in order to better understand recurrence patterns and suggest an alternative approach to open arthrotomy. Methods: Using predetermined inclusion and exclusion criteria, the PubMed and Embase databases were searched for relevant articles related to arthroscopic surgical management of patients with confirmed SC of the ankle. Article selection and data abstraction were performed in 3 steps by 3 independent reviewers. Results: The initial search retrieved 116 articles, of which 15 were included. Those studies included 22 patients (14 to 63 years of age; 77% male) who were followed for a mean of 27 months (range, 8 weeks to 12 years) postoperatively. The cases represented a mix of primary and secondary SC etiologies, and almost entirely stage-III disease. Arthroscopic synovectomy with excision of loose bodies was a consistent feature of treatment, and bursectomy, debridement of osteochondral lesions or involved tendons, and osteophyte resection were performed as indicated. All but 1 case employed an anterior approach including anteromedial and anterolateral portals, and in several cases a 4-portal technique was used, which was subsequently proposed as a necessary approach for the definitive treatment of ankle SC. On the basis of the available data, complication and recurrence rates following arthroscopic management were very low. Conclusions: A growing pool of evidence is emerging to suggest favorable outcomes for arthroscopic treatment of SC of the ankle joint. However, more data on patient and surgical variables, as well as comparative studies with longer follow-up, are needed in order to draw definitive conclusions. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
Introduction: The novel coronavirus has spread rapidly around the world with particularly high mortality in the elderly. Care and nursing homes have become the sites of greatest concentration of cases. We intended to review 30-day mortality of COVID-19 patients with hip fractures. This is relevant given the disease impact in this age group. Methods: Medline and Embase databases were searched for relevant studies linked to mortality and morbidity in COVID-19 patients who have undergone non-elective hip surgeries using the keywords “COVID-19”OR “SARS-cov-2”OR “Coronavirus Infections”; AND “Surgery”OR “Hip”OR “Fracture”OR “Orthopedics.” We included all patients with hip fractures, but excluded pathological fractures and other non-traumatic hip pathologies. Four-hundred and eighty-one articles were identified for screening, in addition to an unpublished case-series of 67 patients that have 3 cases turned positive for COVID 19, yielding a total of 50patients for the final review. Results: The study included 4 articles published until May 9th 2020 and a case-series: 26(52%) patients were females; the median age was 86years; hypertension(53.6%), diabetes mellitus type II(28.6%), and coronary artery heart disease(25%) were the most common comorbidities; 34(68%) patients had intertrochanteric hip fracture and 16(32%) patients had femoral neck fractures; 22(59.5%) patients underwent cephalomedullary nail fixation, 12(32.4%) patients had hemiarthroplasty, and for 3(8.1%) patients, the type of surgery was not documented; 20(40%) patients died(12patients died before the surgery and 8died after surgery at a median time of 3days), 29(76.3%) patients had an unremarkable course throughout hospitalization and were discharged including 1(2.6%) patient managed non-operatively, and 1(2.6%) patient was admitted to the ICU after the surgery but eventually discharged. Conclusion: COVID-19 infected elderly patients have a higher 30-days mortality rate compared to non-COVID-19 infected cases. Further studies are warranted to look at the morbidity and mortality rates in COVID-19 positive patients with hip fractures and to investigate how these outcomes can be improved. Level of evidence: Level IV
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
