Periprosthetic fractures of the knee: a comprehensive review.

Demographic changes have resulted in an increase in the number of older patients diagnosed with degenerative joint disease. Developments in the field of joint arthroplasty allow a broader population to improve their lifestyles. An increased demand for knee arthroplasty has led to a rise in operations performed worldwide. Although there has been a constant propagation of technology and an increase in medical staffing at a professional level, many patients still encounter complications. Though rare, these factors may lead to life-threatening scenarios and a devastating effect on the success of the operation. One such rare complication includes periprosthetic fractures around the knee, a complex injury which requires a cautious and experienced approach. In this review, we analyze the prevalence, risk factors and classification, investigation and treatment options for periprosthetic fractures with total knee arthroplasty.

Awareness of diagnostic and clinical features of fibromyalgia among orthopedic surgeons.

Fibromyalgia Syndrome (FMS) is a chronic pain syndrome characterized by widespread musculoskeletal pain and fatigue. The current study was designed to evaluate the awareness and skills of orthopedic surgeons (OS) regarding FMS diagnosis and treatment. For the examination of awareness and familiarity of OS in Israel to Fibromyalgia, a questionnaire-based survey was conducted. Two hundred and nineteen OS, residents and specialists, were asked anonymously about awareness, knowledge, and treatment of FM. Multivariable statistical analysis was performed. 91 % (199) of responders reported that they recognized the disease. Notwithstanding, the mean knowledge score was 7.6 out of 17. In addition, OS who were trained in the south of Israel were found to have a better degree of knowledge about FM (9.7 vs. 7.4; p < 0.03). The awareness and knowledge among OS regarding FM needs to be improved. OS who were trained in the south of Israel were found to have better degree of knowledge regarding FM.

Possible origins and implications of atypical morphologies and domestication-like traits in wild golden jackals (Canis aureus).

Deciphering the origins of phenotypic variations in natural animal populations is a challenging topic for evolutionary and conservation biologists. Atypical morphologies in mammals are usually attributed to interspecific hybridisation or de-novo mutations. Here we report the case of four golden jackals (Canis aureus), that were observed during a camera-trapping wildlife survey in Northern Israel, displaying anomalous morphological traits, such as white patches, an upturned tail, and long thick fur which resemble features of domesticated mammals. Another individual was culled under permit and was genetically and morphologically examined. Paternal and nuclear genetic profiles, as well as geometric morphometric data, identified this individual as a golden jackal rather than a recent dog/wolf-jackal hybrid. Its maternal haplotype suggested past introgression of African wolf (Canis lupaster) mitochondrial DNA, as previously documented in other jackals from Israel. When viewed in the context of the jackal as an overabundant species in Israel, the rural nature of the surveyed area, the abundance of anthropogenic waste, and molecular and morphological findings, the possibility of an individual presenting incipient stages of domestication should also be considered.

Analysis of Trauma Injuries Among the Minority Population in Southern Israel-a District-Wide Study.

BACKGROUND: We compared characteristics of traumatic injury between the Bedouin subpopulation, the largest minority group in southern Israel, and the other residents in this region. METHODS: We assessed all the patients admitted with traumatic injuries during 2014-2018 to the only regional hospital in southern Israel. RESULTS: The cohort comprised 10,734 patients, 4553 (42.5%) of Bedouin origin. Compared to the non-Bedouin subpopulation, in the Bedouin subpopulation, the proportion of injuries that occurred in males was higher, 74.3% vs. 53.7%, P < 0.001, and the proportion of burn injuries that occurred in children aged 0-14 years was higher, 84% vs. 49%. Among the Bedouin and non-Bedouin patients, the respective proportions with penetrating injuries were 10.7 and 5.4%; the respective proportions who arrived at the hospital by private vehicles were 62.0 and 33.1%. In multivariate analysis, the variables that were significant for increased odds for severe trauma were Bedouin origin, male gender, and arrival to the emergency room at night. CONCLUSION: This study highlights the lack of access to basic infrastructure and healthcare among Bedouins in southern Israel. The high proportion of penetrating injuries in this subpopulation is apparently due to explosions of unexploded ordnance. The unavailability of electricity and waste removal in unrecognized villages contributes to burn injuries among Bedouin children. Poor accessibility of healthcare facilities and emergency medical transportation necessitates travel to hospitals by private car. The findings should direct trauma prevention programs to reduce burn and penetrating injuries and to increase accessibility to healthcare.

[Arthroscopic treatment for osteoarthritic knee].

Osteoarthritis (OA) is the leading cause of knee morbidity. Age and overweight are the main risk factors for development of knee OA. The majority of patients respond to conservative treatment. For those who don't, surgical treatment is the only alternative. Arthroscopic surgery for the osteoarthritic knee is a well known procedure. Recently, numerous publications addressed the advantages of arthroscopic treatment for this indication. Some of the publications concluded that arthroscopic treatment for knee OA equals placebo. Others found temporary relief of symptoms. Among special subgroup of patients, in which acute pain exacerbation, mechanical block or early OA, utilizing arthroscopic techniques revealed satisfactory results. In this review, we discuss the indications and contraindications for arthroscopic treatment of the osteoarthritic knee according to the latest literature.
