Pelvic bone surgery and natural delivery: absolute and relative contraindications

Objective. The gynecologist often involves the orthopaedic surgeon in the evaluation of pregnant women with previous medical history of pelvic surgery who will give birth. Young women can receive pelvic surgery for proximal femoral fractures, sacro-iliac or pelvic ring fractures, avascular necrosis of the femoral head, hip dysplasia and severe ankylosing spondylitis. The aim of this study is to determine whether such women can accomplish a natural delivery or should have caesarean delivery (C-section). Methods. Pubmed and the Cochrane Database of Reviews were searched for manuscripts including the years 1970 to present. Results. It is important to discriminate between pathological and/or post-surgical conditions affecting the coxo-femoral joint which constitute an absolute contraindication to vaginal delivery from other circumstances that may have a relative contraindication. Orthopaedic relative indications for C-section may include coxo-femoral pathologies where coxo-femoral joint range of motion is limited and women cannot assume a given position that is deemed necessary by the obstetric specialist for natural delivery. Conditions requiring C-section are those producing an insufficient width of the bony birth canal; when the transverse mid-pelvis diameter is <9.5 cm, then the probability of C-section is increased. Conclusions. It is not mandatory to perform a C-section in all women with a past medical history of pelvic surgery; accurate medical history collection, imaging technologies and ultrasound make it possible decide if a C-section is compulsory

Celecoxib versus indomethacin as prevention of arthrofibrosis. A perspective case-control study

Nonsteroidal anti-inflammatory drugs (NSAIDs) remain the most commonly utilised prophylaxis to reduce arthrofibrosis (AF) related to the inflammatory response which leads to a pathological condition called arthrofibrosis. Several NSAIDs have shown to be effective, although postoperative indomethacin has been the historical gold standard. More recently, credit has been given to the use of COX-2 selective inhibitors, due to concerns over gastrointestinal effects, as peptic ulcers, with non-selective COX. However, to date, few studies have compared the therapeutic effects of the two drugs. The aim of this study is to compare the postoperative administration of indomethacin and celecoxib in patients with diagnosis of AF treated with arthroscopic lysis and evaluate joint recovery. In this prospective study, 42 patients were diagnosed with hip, knee and elbow residual AF. The inclusion criteria were age > 18 years and a diagnosis of residual AF, following exposure to a previous traumatic event or surgical treatment; exclusion criteria were patients with 35 or < 18 kg/m2, affected by peripherical neuropathies and presence of heavy functional limitations, active infection, complex regional pain syndrome diagnoses. All patients underwent to arthroscopy, operated by a single surgeon with the same team in the same clinic and postoperatively were randomly divided into two groups, one treated with indomethacin, and the other with celecoxib. Of the patients examined, the following parameter was considered: joint range of motion (ROM) preintervention and post-intervention at 3 months and after 12 months. ROM was analysed with Student t test. The comparison of the ROM between both the 3 months postoperative groups has been shown to be not statistically significant. On the other hand, after 1 year, t-Student test referred to preoperative condition was significantly in favour of the group treated with celecoxib (p = 0.02). Lastly, neither celecoxib nor indomethacin showed any gastrointestinal side effects

Current methods and treatment options for interprosthetic femur fracture: an overview

As life expectation is prolonged and the elderly population increases, we are witnessing a growth in the number of prosthesis implanted; therefore, an increase in interprosthetic femoral fractures can be expected in the next future. For this reason, a proper and specific classification system needs to be.Nowadays, depending on the localization of the fracture, Vancouver or Rorabeck classifications are used, and some attempts have been made to create a new one or adjust and adapt the previously mentioned systems. However, there is no unique classification system that is accepted worldwide.The goal would be a classification that permits identifying the correct surgical treatment based on the type of interprosthetic femoral fracture. A pragmatic grading scale to provide a standardised approach, so that the best possible outcomes could be achieved. Despite minimal diffusion, in our opinion the Pires classification system should be universally accepted and used

Studi sui tratti di qualità negativa nelle nuove viti mediamente resistenti alle malattie fungine

The varieties of vines tolerant to the main fungal diseases are the object of growing interest because they require fewer treatments for the production of quality grapes. These varieties are considered qualitatively unsuitable especially for some characteristics such as the foxy aroma, the level of anthocyanin diglucosides and the level of methyl alcohol in wines. In the three-year period 2016-2018, from a population of 74 medium resistant varieties placed in a single collection, in Marlengo (BZ), young leaves were taken for DNA analysis; annually 2 surveys of the OIV 452 453, 455 and 456 descriptors were carried out, and, at 18° Brix, sombunches were collected for the analysis of different metabolites. Nano-vinifications were carried out for 32 genotypes. Genotypes with different levels of stacked loci associated with resistance to downy and powdery mildew were detected, with different resistance behaviors over the years. Only some genotypes have aromas of foxy and only 20% of the genotypes analyzed have levels of anthocyanin diglucosides higher than the levels required by current legislation. Some vinifications showed methanol levels higher than the legal limit set. High percentages of genotypes respected the legal levels of metabolites required by current regulations and only genotypes with the presence of V. labrusca showed the aroma of foxy

Is it really advantageous to operate proximal femoral fractures within 48 h from diagnosis? – A multicentric retrospective study exploiting COVID pandemic-related delays in time to surgery

Objectives: Hip fractures in the elderly are common injuries that need timely surgical management. Since the beginning of the pandemic, patients with a proximal femoral fracture (PFF) experienced a delay in time to surgery. The primary aim of this study was to evaluate a possible variation in mortality in patients with PFF when comparing COVID-19 negative versus positive. Methods: This is a multicentric and retrospective study including 3232 patients with PFF who underwent surgical management. The variables taken into account were age, gender, the time elapsed between arrival at the emergency room and intervention, pre-operative American Society of Anesthesiology score, pre-operative cardiovascular and respiratory disease, and 10-day/1-month/6-month mortality. For 2020, we had an additional column, “COVID-19 swab positivity.” Results: COVID-19 infection represents an independent mortality risk factor in patients with PFFs. Despite the delay in time-to-surgery occurring in 2020, no statistically significant variation in terms of mortality was detected. Within our sample, a statistically significant difference was not detected in terms of mortality at 6 months, in patients operated within and beyond 48 h, as well as no difference between those operated within or after 12/24/72 h. The mortality rate among subjects with PFF who tested positive for COVID-19 was statistically significantly higher than in patients with PFF who tested. COVID-19 positivity resulted in an independent factor for mortality after PFF. Conclusion: Despite the most recent literature recommending operating PFF patients as soon as possible, no significant difference in mortality was found among patients operated before or after 48 h from diagnosis

Dual mobility for total hip arthroplasty revision surgery: A systematic review and metanalysis

Introduction: Revision THA (R-THA) is thought to have a higher complication rate if compared to primary THA. Dual Mobility (DM) implants have been designed aiming for achieving greater stability, with good clinical results. However, scarce material can be found about the real improvements provided by this type of implant compared to traditional implant in Revisions of Total Hip Arthroplasties. Methods: A systematic review and meta-analysis of comparative studies were performed in December 2019. This was in accordance with the guidelines of Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Our primary outcome measure was overall survivorship and dislocation rate, either treated with a conservative method or requiring surgery. Results: Regarding the overall implant survival, we found a slight significant risk ratio, with a statistically meaningful difference between the two groups in questions in favour of the DM implant. A statistically significant difference in favour of the DM group turned out considering only the Dislocation rate Risk ratio and the aseptic loosening risk as well. No statistical difference was found between the two groups about the risk ratio of infection. Discussion: A steady increase of evidence is demonstrating the efficacy of using a DM cup system in THA revisions with low dislocation rates, but currently there is no study in the literature that demonstrates with statistically significant evidence. The main finding of the present study is that implant’s Survivor and prevention of dislocation at medium follow-up showed better results with a DM if compared to a fixed-bearing cup, for Revision THA

Effect of an Innovative Biofeedback Insole on Patient Rehabilitation after Total Knee Arthroplasty

Partial weight bearing is fundamental to rehabilitation in the early stages following lower limb surgery. However, it remains debated as to how to properly achieve partial weight bearing while avoiding complications from excessive or premature load. Of the devices currently on the market, instrumented insoles coupled with force-sensitive resistors (FSRs) are among the best options in today’s clinical practice. Still, although several of these systems have been developed in the last few years, only some have been validated, leaving insufficient information on their application in rehabilitation after total knee replacement (TKR). To address this research gap, we evaluated the performance of an innovative biofeedback insole system featuring an extremely low response time for real-time force feedback. We randomly recruited 30 patients who underwent total knee arthroplasty. All patients used the new programmable insole for partial weight bearing per postoperative rehabilitation protocol. Our results confirm their inability to perform a correct gait with low partial weight bearing (<30–50% of their bodyweight). Partial weight bearing with a correct gait in the post-operative period is not obtainable without a measuring system. This new biofeedback insole is thus one of the most indicated and can improve rehabilitation compliance, therefore allowing continual patient monitoring for faster discharge and fast-track rehabilitation.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

One-stage procedure for open tibial fractures: feasible without orthoplastic surgery?

Background: Open tibial fractures are mostly the result of high-energy traumas and often involve severe injuries with extensive bone and soft tissue loss, damage of muscles and neurovascular structures. Over recent- years, - the growth of Ortho-Plastic teams, as a well-coordinated bone, joint and soft tissue treatment, contributed to change the approach to these fractures and to achieve higher successful results in lower limb salvage. Unfortunately, many hospitals cannot benefit of a combined team in emergency, and the orthopedic surgeon is forced to manage personally these kinds of traumas. Methods: We retrospectively reviewed all the open tibial fractures treated at our Orthopaedic Department over the last 10 years, in order to assess the treatments performed (one-stage fixation with Intramedullary Nailing or Open Reduction Internal Fixation - ORIF, versus two/multiple-stage fixation with temporary External Fixation followed by nailing or ORIF) and the differences in the outcome between the different methods. Purpose: Based on our experience and review of the literature, the purpose of this paper is to define what cases can be managed by a single-stage orthopaedic approach, and when the orthopaedist should lay down his arms in favor of other specialties

Safety of spinal anesthesia and analysis of cerebrospinal fluid in SARS-CoV-2 pregnant women undergoing cesarean section: an observational prospective study

Abstract Background Systemic infection has always been considered a relative contraindication to neuraxial anesthesia, despite the fact that infectious complications are relatively uncommon. Pregnancy-related physiological changes and coronavirus disease (COVID-19) neurotropic features may facilitate the virus’ entry into the central nervous system. The principal aim of this study was to test the safety of spinal anesthesia in “severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2)-positive pregnant women and to examine cerebrospinal fluid (CSF) characteristics. Methods We conducted a prospective observational single-center study in asymptomatic or paucisymptomatic consecutive pregnant SARS-CoV-2 patients who underwent spinal anesthesia for cesarean section. Women with severe infection were excluded because they underwent general anesthesia. At the time of spinal anesthesia, we collected CSF samples, and then we performed a chemical-physical analysis to look for signs of inflammation and for SARS-CoV-2 genome. Results We included 26 women. No spinal anesthesia complications were reported in the perioperative period and after 2 months. All CSF samples were crystal clear, and all physical-chemical values were within physiological ranges: the median concentration of CSF/plasma glucose ratio was 0.66, IQR 0.5500 (0.6000–0.7100), and the average CSF protein concentration value was 23.2 mg/dl (SD 4.87). In all samples, genomes of SARS-CoV-2 and other neurotropic viruses were not detected. Conclusions Spinal anesthesia was safe in SARS-CoV-2 pregnant women with mild disease; no clinical maternal complications were detected, and no CSF changes indicative of inflammatory or infectious diseases that would compromise the safety of the procedure were found

Breastfeeding Determinants in Healthy Term Newborns

Breastfeeding is the normative standard for infant feeding. Despite its established benefits, different factors can affect breastfeeding rates over time. The purpose of this study was to evaluate breastfeeding determinants in healthy term newborns during the first three months of life. A prospective, observational, single-center study was conducted in the nursery of Fondazione IRCCS Ca’ Granda Ospedale Maggiore Policlinico in Milan, Italy. The mother-baby dyads that were admitted to the Clinic in January and February 2017 were enrolled. Only healthy term babies with birth weight ≥10th percentile for gestational age were included. Data were collected through medical records and questionnaires administered during the follow-up period. Then, we fitted univariate and multivariate logistic models and calculated odds ratios. 746 dyads were included but 640 completed the study. The factors found to be favoring breastfeeding were a previous successful breastfeeding experience, a higher level of education of the mother, attending prenatal classes, no use of pacifier, rooming in practice, and breastfeeding on demand. Factors acting negatively on breastfeeding were advanced maternal age, non-spontaneous delivery, perception of low milk supply, mastitis, and nipple fissures. This study highlights the need to individualize the assistance provide to breastfeeding mothers, paying special attention to personal experiences
