Total hip arthroplasty and sexual activity: a systematic review.

Hip discomfort due to degenerative pathologies causes limitations in the everyday activities of patients, including sexual activity. To address such limitations, patients are usually treated with total hip arthroplasty (THA). The aim of this systematic review was to investigate the success of this surgical procedure to ameliorate sexual activity of patients. We performed a comprehensive research of four electronic databases for articles pertaining to the benefits of THA on sexual activity. Exclusion criteria included articles not in English. The search initially yielded 34 articles. Two authors subsequently read all abstracts and excluded all studies unrelated to the topic, leaving 16 articles for further evaluation. Sixteen articles filtered by orthopaedic departments were included in this review. A total of 2391 patients were considered. Pre- and postoperative reports on sexual concerns have been evaluated and compared. The current literature suggests that sexual life is improved after THA. Patient education regarding postoperative expectations and resumption of sexual activity is severely lacking and the majority of surgeons offer little or no information on the subject. Specifically designed studies on the subject are required to evaluate the effects of surgery and approaches on postoperative restrictions.

How to prevent dislocation after revision total hip arthroplasty: a systematic review of the risk factors and a focus on treatment options.

BACKGROUND: Dislocation represents the most common complication after revision total hip arthroplasty (rTHA). Understanding risk factors for dislocation has a great clinical relevance for every hip surgeon in order to consider all surgical options for effective planning. The aim of this systematic review was to answer two main questions-(1) what are the risk factors for instability after rTHA? and (2) what are the best preoperative assessments and surgical options to avoid dislocation after rTHA? MATERIALS AND METHODS: Scientific databases were accessed to identify papers dealing with prevention and treatment of dislocation after rTHA. We performed a search using the keywords 'revision hip arthroplasty' and 'dislocation', 'instability', 'outcome', 'failure', 'treatment'. After removal of duplicates and exclusion of works published in different languages, 33 articles were reviewed completely. RESULTS: Risk factors were analysed in order to establish the most relevant and evidence-based treatments available in the current literature. CONCLUSIONS: The risk of dislocation after rTHA can be reduced using some precautions inferred from the literature. The use of a larger femoral and acetabular component, elevated rim liner and dual mobility implants can significantly reduce the risk of dislocation after rTHA. However, care must be taken regarding patient-related risk factors since these cannot be addressed and modified. Hence, a complete evaluation of risk factors should be performed for each patient and procedure before starting rTHA.

Thalassemia-associated osteoporosis: a systematic review on treatment and brief overview of the disease.

Thalassemia-associated osteoporosis constitutes a major complication in patients with thalassemia. This review presents the existing studies on the treatment of thalassemia-associated osteoporosis and discusses the management of this debilitating complication. A brief presentation of the disease characteristics and pathogenetic mechanisms is also provided. The life expectancy of patients with thalassemia has increased markedly in recent years resulting in the aging of the population and the emergence of new comorbidities. The majority of patients with thalassemia have low bone mineral density and experience lifelong fracture rates as high as 71 %. The pathogenesis of thalassemia-associated osteoporosis (TAO) is multifactorial with anemia and iron overload playing crucial role in its development. Data concerning the prevention and treatment of TAO are extremely limited. We performed a literature research in Pubmed and Scopus to identify interventional studies evaluating the effects of various agents on TAO. Seventeen studies were retrieved. We present the results of these studies as well as a brief overview of TAO including presentation, pathogenesis, and management. Most of the studies identified are of poor quality, are not randomized controlled, and include small number of participants. There are no data concerning effects on fracture rates. Bisphosphonates are the most widely studied agents and among them zoledronic acid is the most well studied. Hormone replacement treatment (HRT) shows beneficial but small effects. Denosumab and strontium ranelate have each been evaluated in only a single study, while there are no data about the effects of anabolic agents. Given the increased life expectancy and the increase in fracture rates with age, more data about the management of TAO are warranted. Moreover, due to the need for lifelong management starting at young age, careful treatment plans which may include sequential treatment may often be required. However, currently, there are no relevant data available.

Atypical femoral fracture in a beta-thalassemia major patient with previous bisphosphonate use: case report and a review of the literature.

There are numerous studies presenting the beneficial effect of bisphosphonates (BPs) on bone disease of patients suffering from beta-thalassemia major (TM). Although BPs have been widely used, adverse events have been described including atypical femoral fractures (AFF). In the present case, a male adult patient suffering from TM sustained an AFF fulfilling all major and two minor criteria. Before AFF, the patient had been treated with zoledronic acid for three years and remained another one year without osteoporosis therapy. To our knowledge, this is the first reported case of AFF in a patient suffering from TM, probably due to the small sample size of patients with thalassemia. The purpose of the present case is to increase the awareness amongst haematologists, who mainly deal with TM patients, of the adverse events of BP use.
