Treatment and rehabilitation of subtalar dislocations: A case series and a review of the literature.

Introduction: Subtalar dislocation is an uncommon orthopaedic pathology, representing 1 % of all traumatic injuries of the foot and 1-2 % of all dislocations, mostly affecting young male adults. While its urgent treatment consisting in reduction and immobilization of the dislocation has been well described, disagreement exists about post-operative management with specific regards to immobilization length and rehabilitation protocols.

Materials And Method: A case series of traumatic subtalar dislocations treated with urgent reduction, a mean of 4 weeks immobilization and subsequent rehabilitation is presented, with 1-year minimum clinical and subjective follow up.

Arthroscopic Debridement Enhanced by Intra-Articular Antibiotic-Loaded Calcium Sulphate Beads for Septic Arthritis of a Native Knee Following Iatrogenic Joint Injection: A Case Report.

Septic arthritis (SA) represents an orthopedics urgency and mainly affects the knee joint. Due to its devastating effects on cartilage, immediate management is crucial. SA is characterized by an annual incidence of 2 to 10 cases per 100,000 individuals, with mortality rates fluctuating between 0.

Biological Patch in the Repair of Rotator Cuff Tears: Functional and Clinical Evaluation of Twenty-Three Cases with a Mean Follow-Up of Six Years.

Rotator cuff (RC) repair leads to less than optimal results when dealing with massive lesions, so the use of scaffolds as biological support has been proposed to improve RC repair site biology. The present study aims to evaluate the clinical and radiographical outcomes of a series of patients suffering from massive or irreparable RC tears treated with patch (porcine or human scaffolds) repair (augmentation or bridging). Twenty-three patients with a minimum follow-up of 24 months were subjectively, clinically, and radiographically assessed before and after surgery.

A Reverse Shoulder Arthroplasty Implantation With Custom-Made Humerus and Intraoperative GPS Navigation in a Rare Case of Unilateral Hip and Shoulder Dysplasia Associated With a Bone Marrow Mosaic Truncating Variant: Case Report.

Joint dysplasias always represent a great challenge for prosthetic surgeons. The common altered anatomical landmarks and the subversion of the anatomy of soft tissues surrounding the dysplastic joint are problems that can cause difficulties if approached with standard methods. Together with the resolution of functional issues related to dysplasia, the understanding of the underlying cause is fundamental.

A novel "7 sutures and 8 knots" surgical technique in reverse shoulder arthroplasty for proximal humeral fractures: tuberosity healing improves short-term clinical results.

Background: Complex proximal humeral fractures (cPHFs) represent an important public health concern, and reverse shoulder arthroplasty (RSA) has emerged as a feasible treatment option in the elderly with high functional demands. Recent studies have shown that tuberosity healing leads to better clinical outcomes and an improved range of motion. However, the best surgical technique for the management of the tuberosities is still a topic of debate.

Impact of COVID-19 Pandemic on Treatment and Outcome of Fragility Hip Fractures In Non-COVID Patients: Comparison Between the Lockdown Period, a Historical Series and the "Pandemic Normality" in a Single Institution.

Introduction: The COVID-19 pandemic has affected and is still deeply affecting all aspects of public life. World governments have been forced to enact restrictive measures to stem the contagion which have led to a decrease in the movement of people within national territory and to a redirection of health care resources with a suspension of non-urgent procedures. In Italy, a lockdown was imposed from March 9 to May 3, 2020.

Treatment Algorithm of Periprosthetic Femoral Fracturens.

The ever-expanding indications for total hip arthroplasty are leading to more implants being placed in younger as well as in older patients with high functional demand. Also, prolonged life expectancy is contributing to an overall increment of periprosthetic femoral fractures. The Vancouver classification has been the most used for guiding the surgeon choice since its proposal in 1995.

Combined Surgical and Medical Treatment for Vancouver B1 and C Periprosthetic Femoral Fractures: A Proposal of a Therapeutic Algorithm While Retaining the Original Stable Stem.

Introduction: There is lack of consensus regarding best operative fixation strategy for periprosthetic femoral fractures (PFFs) around a stable stem. Evidence exists that some patterns of fracture around a stable stem are better treated with revision surgery than with standard fixation. Anyway, a more aggressive surgical procedure together with medical treatment could allow for stem retention, and reduced risk of nonunion/hardware failure, even in these cases.

Pre-Operative CT-Based Planning Integrated With Intra-Operative Navigation in Reverse Shoulder Arthroplasty: Data Acquisition and Analysis Protocol, and Preliminary Results of Navigated Versus Conventional Surgery.

Reverse total shoulder arthroplasty (RSA) successfully restores shoulder function in different conditions. Glenoid baseplate fixation and positioning seem to be the most important factors influencing RSA survival. When scapular anatomy is distorted (eccentric osteoarthrirtis, rotator cuff arthropathy), optimal baseplate positioning and secure screw purchase can be challenging.

A 2-free-end flexor carpi radialis tendon graft for treating a complex index finger extensor tendon injury.

Background: Volar plating has increasingly become the most used technique for the treatment of unstable distal radius fractures due to the low soft-tissue disturbance and its biomechanical reliability, which allows the early mobilization of the wrist. One of the main goals of the volar locking compression plates design is to avoid those soft tissue complications historically associated to the dorsal plating. However, extensor tendon complications can not be completely excluded.

GPS guided reverse shoulder arthroplasty.

Background And Aim Of The Work: The reverse shoulder arthroplasty (RSA) has risen exponentially, this has entailed an increasing number of complications and reoperations. In RSA, loads are transferred directly to the glenoid component. As a result, failure of the glenoid component is one of the most common complications.

Posterior Tibial Tendon Rupture Associated With Anterolateral Distal Tibial and Medial Malleolar Fracture and a Novel Pattern of Tibiofibular Syndesmotic Injury: A Case Report and Review of the Literature.

A posterior tibial tendon (PTT) rupture associated with ankle fractures is a very rare condition. Ankle pronation and external rotation (PER) movement are the typical traumatic mechanism. This injury is frequently overlooked preoperatively.

The Challenges of the Femoral Bone Loss in the Management of the Floating Knee IIB According Fraser: A Case Report.

Introduction: This case report describes the management and the possible therapeutic solutions for the treatment of femoral bone loss associated with an open fracture IIIB Gustilo Andersonin a polytrauma that includes floating knee (GF) Fraser IIB from damage control orthopedics to final treatment.

Case Report: The patient was treated with an external fixator femorotibial bridge after extensive cleaning and debridement of open fractures. After 17-day post-trauma, we substitute the fixator with a less invasive stabilization system plate and screws with contralateral allograft bone strut.

Use of autologous bone marrow cells concentrate enriched with platelet-fibrin on extensor mechanism allograft reconstruction for extensor mechanism failure following total knee arthroplasty.

Allografts techniques remain the best reconstructive strategy for chronic extensor mechanism lesions after total knee arthroplasty (3) but outcomes depend strictly on the host tissue-allograft junctions healing. The purpose of this study is to evaluate if modern techniques of adding autologous bone marrow cells concentrate enriched with platelet-rich fibrin, provide better healing of the allograft. We present the case of an 86 years old patient affected by patellar tendon rupture after TKA.

Comparison of two iron gluconate treatment modalities in chronic hemodialysis patients: results of a randomized trial.

Background: Iron supplementation in chronic hemodialyzed patients is not yet completely defined concerning the dosing regimen. This study aimed to evaluate the effects of the same iron load administered in different regimens on anemia, iron status and the reticulocyte (Ret) subpopulation patterns in stable patients on chronic hemodialysis (HD).

Patients And Methods: Seventeen patients undergoing thrice-weekly chronic HD and receiving stable alphaerythropoietin therapy with absolute iron deficiency (transferrin saturation (TSAT) <20%, ferritin (Frt) <100 ng/mL) were randomly divided into two groups: group A (n=9) received 20.

[Alterations of cardiac output during bicarbonate hemodialysis and its relationship with other hemodynamic parameters].

Purpose: Time course of cardiac output (CO) and other hemodynamic parameters were measured during hemodialysis (HD). Our aims were to identify a characteristic CO profile and investigate the relationship with other hemodynamic parameters.

Patients And Methods: CO was measured with ultrasound dilution method in 45 chronic hemodynamically stable HD patients.

[Italian Registry of Dialysis and Transplantation: 1996-2001 experience].

The Italian Registry of Dialysis and Transplantation (RIDT) was born in 1996 under the aegis of the Italian Society of Nephrology, and it is organized as a federation of regional registries. This study aimed to completely revise the epidemiological data collected during the first 5 yrs (1996-2001) of RIDT activity to evaluate the trends of the main epidemiological features. During this period, regional registries were not always able to assure complete and exhaustive information according to RIDT requirements, owing to different levels of organization and functioning.

Blood volume controlled hemodialysis in hypotension-prone patients: a randomized, multicenter controlled trial.

Background: Recently we have devised and tested a biofeedback system for controlling blood volume (BV) changes during hemodialysis (HD) along an ideal trajectory (blood volume tracking, BVT), continuously modifying the weight loss rate and dialysate conductivity. This multicenter, prospective, randomized, crossover study aimed to clarify whether BVT (treatment B) can improve hypotension-prone patients' treatment tolerance, compared with conventional hemodialysis (treatment A).

Methods: Thirty-six hypotension-prone patients enrolled from 10 hemodialysis (HD) centers were randomly assigned to either of the study sequences ABAB or BABA, each lasting four months.

Anti-GBM nephritis complicating diabetic nephropathy.

There are several reports of glomerulonephritis (GN) in diabetics or patients with diabetic glomerulosclerosis. Cases of rapidly progressive GN where crescentic histologic changes are superimposed on diabetic glomerulosclerosis are very unusual. We report the case of a patient with type I diabetes mellitus, who developed rapidly progressive renal insufficiency.

Continuous urea monitoring in hemodialysis: a model approach to forecast dialytic performance. Results of a multicenter study.

Background: A urea biosensor, inserted into the ultrafiltrate collection-line of paired filtration dialysis (PFD), not only allows on-line dialysis quantification, but also forecasts final (Cend) and 30 min equilibrated urea concentration (Ceq), the most reliable value for calculating dialysis efficiency. The urea biosensor processes plasma ultrafiltrate continuously, delivering a large amount of data to the computer, which estimates the parameters by a mathematical model, thus predicting the whole urea profile with rebound.

Methods: A multicenter randomized trial on 41 patients was conducted to ascertain the ability of a two-pool variable-volume urea model to forecast Cend and Ceq at 60 and 90 min after the start of dialysis.

Adequacy in hemodialysis: new concepts derived from online urea monitoring.

Background: The estimation of urea kinetic parameters [urea generation rate (Gu), normalized protein catabolic rate (NPCR), and dialysis dose (Kt/V)] is routinely performed during a single hemodialysis session as a representative sample of a stable series. To ascertain whether the stability assumption is tenable and to estimate the variability of urea kinetic parameters, a number of stable patients on regular dialysis treatment in their usual clinical setting were followed.

Methods: Thirteen stable patients on regular hemodialysis aged 61 +/- 11 were monitored from 5 to 24 weeks (median, 10 weeks) with the urea biosensor system in double-chamber hemodiafiltration.
