Background This paper's purpose was to analyze clinical results obtained with trapeziometacarpal arthrodesis and complications comparing different osteosynthesis systems. Methods Thirty-seven trapeziometacarpal arthrodesis were performed in our center in a 7-year period, with a mean age of 52 years and 34 months of follow-up. The implants were distributed homogenously into three groups, using bone grafts in 12.5% of them. Results A 75% achieved complete consolidation with a mean postsurgical Visual Analog Scale (VAS) of 2.4, Kapandji Opposition Score (KOS) of 8.1, lateral pinch strength of 12.1 kg, tripod pinch strength of 3.6 kg, and tip-to-tip strength of 1.5 kg. Consolidation was not achieved in nine patients, of which five were asymptomatic, three reoperated on trapeziectomy and tenosuspension, and one rearthrodesis. No statistical association was found between the implant used and pseudoarthrosis (p = 0.17), VAS (p = 0.06), or KOS (p = 0.45). Conclusions Trapeziometacarpal arthrodesis reduces pain for well-chosen patients. Nonunion has low clinical significance in most cases and does not seem to depend on the use of allograft or the type of implant but on an appropriate surgical technique.

Introduction Several alternatives are now available when treating posttraumatic acute bone defects. Masquelet's technique represents a safe procedure to treat lower limb open fractures associated with significant bone defects and allows surgeons to try to reduce complications incidence. Material and Methods Retrospective study based on patients´ record files and images (2015-2017). Twelve patients suffering acute bone defect, treated using Masquelet technique, were evaluated. A total of ten patients were finally included after exclusion criteria were applied. Results Average time from injury to first stage surgery was 11 days. Free flaps were required in three cases (two latissimus dorsi and one anterolateral thigh flap). Time to second stage surgery was 115 days on average. As bone graft, reaming irrigation-aspiration system was associated to this technique. Consolidation was achieved in all patients but one after an average time of 8.4 months. There was only one case of limb shortening of 20 mm. There was no case of nonunion or infection, and patients could perform daily basic activities independently. VAS mean score was one point one year after final surgery. Conclusions Masquelet's technique achieves encouraging results when treating lower limb acute bone defects. Using this technique, surgeons could decrease infection incidence in open fractures with severe bone loss. On the other hand, it is a two-stage surgery process, which makes the process longer.

INTRODUCTION Up to 25% of acetabular fractures have poor functional outcomes in short-term follow-up. The aim of our study is to analyze predictors related to poor outcome in surgically treated acetabular fractures. Damage to the femoral head cartilage and poor fracture reduction has been reported as predictors to total hip arthroplasty (THA). MATERIAL AND METHODS retrospective study of 207 consecutive patients with acetabular fractures, over a fourteen-year period. Demographic data, fracture pattern according to AO/OTA, complications related to surgery and predictor variables were analyzed. RESULTS Analyzing predictor variables, we observed seagull sign, femoral head dislocation, femoral osteochondral damage, acetabular marginal impaction, poor acetabular roof congruency after surgery (p 3mm) (p

Introduction: Hip fractures affecting older people are at a higher risk of complications during the SARS-CoV-2 pandemic. The aim of this study is to provide data about proximal femoral fractures management and early outcomes during COVID-19 pandemic compared to the same period in 2019. Material and Methods: Retrospective and comparative study performed in two different periods were analyzed: from March 15, 2020, to April 30, 2020 (the first six weeks of Spain´s current confinement) and the same period in 2019. Data regarding demographics (age and sex, housing), type of fracture, surgical performance, early outcomes (at 30 days), and at 1-year follow-up were collected. A total of 146 patients were evaluated, 89 in 2019 and 57 in 2020. Results: Despite the drop ∼35.6% in hip fractures during SARS-CoV-2 period, distribution (age ( P = 0.985), sex ( P = 0.43), housing ( P = 0.61), type of fracture ( P = 0.41)) and Charlson comorbidity index ( P = 0.12) were similar to a 2019 period. Surgical performance did not worsen in spite of the tough situation and the use of personal protective equipment, improving in some radiological variables (tip-to-apex and calcar reduction). In terms of postoperative outcomes, although there is a tendency to a short-term mortality increase (from 3.4% to 5.2%, P = 0.22), there were no differences at 1-year follow-up (20.2% in 2019 and 20.4% in 2020, P=0.587). In the same line, although in both groups the patients lost functionality at 1 year, there were no significant differences ( P = 0.42). Conclusion: Even in challenging times, protocols and adequate organization ensure proper outcomes, reaching satisfying clinical and surgical outcomes during the COVID-19 pandemic, despite an increasing trend in short term mortality not seen at 1-year follow-up.

Stiffness is a well-known complication after reverse shoulder arthroplasty. Although multiple factors may be involved, the main cause for stiffness is rarely identified. Imaging studies frequently are inconclusive in ruling out mechanical or biological causes. Periprosthetic infection should be always suspected, but the absence of major clinical signs and accurate diagnostic tests is frequent. A lack of objective criteria establishing a diagnosis and when to proceed with revision surgery is often present in such cases. Moreover, additional surgical procedures should be carefully evaluated, as they can represent a point of no return. Shoulder arthroscopy plays an increasingly important role in these cases, either as a diagnostic or therapeutic tool. There are no reports about arthroscopy on stiffness after reverse shoulder arthroplasty. In this Technical Note, we describe an arthroscopic technique aimed to identify potential causes of reverse shoulder arthroplasty stiffness. Subsequent circumferential release is described and discussed.

Purpose:SARS-CoV-2 new scenario has forced health systems to work under extreme stress urging to perform a complete reorganization of the way our means and activities were organized. Orthopedic and trauma have rescheduled their activities to help SARS-CoV-2 units, but trauma patients require also treatment, and no standardized protocols have been established.Methods: Single-center cross-sectional study was performed in a tertiary hospital. Two different periods of time were analyzed: a two-week period time in March 2019 (pre-SARS-CoV-2) and the same period of March 2020 (SARS-CoV-2 pandemic time). Outpatient’s data, emergency activity, surgical procedures and admissions were evaluated. Surgeons and patient´s opinion was also evaluated using a survey.Results:A total of ~16k (15.953) patients were evaluated. Scheduled clinical appointments decreased by ~22%. Urgent consultations and discharge from clinics also descended (~37% and ~20% respectively). Telemedicine was used in 90% of outpatient clinical evaluations. No elective surgical procedures during SARS-CoV-2 time were scheduled, and subtracting the effect of elective surgeries, a reduction of inpatient surgeries, from ~85% to ~59%. Patients delayed trauma assistance more than 48 hours in 13 cases (35%). Preoperative admission for hip fractures decreased in 10 hours on average. Finally surveys stated that patients were more in favor than surgeons to this new way to evaluate orthopedic and trauma patients based strongly on telemedicine.ConclusionDetailed protocols should be standardized for surgical departments during the pandemic. This paper offers a general view in how this virus affects an orthopedic unit and could serve as a protocol and example for orthopedic and trauma units. Even in the worst scenario, an orthopedic and Trauma unit could offer an effective, efficient and quality service. SARS-CoV-2 will set up a new paradigm for health care in orthopedics and trauma.

There is scarce information in the literature dealing with the clinical presentation, management and oncologic outcomes of skeletal muscle metastases (SMM). We sought to perform a systematic review of the literature to investigate: (1) tumor characteristics of SMM, (2) therapeutic approach, and (3) oncological outcomes. A systematic review of the literature was performed using PubMed and EMBASE search engines. A total of 3231 references were reviewed and 49 studies were included. Demographic data, presentation characteristics, and oncological outcomes were recorded. Statistical analysis was performed using SPSS 22.0 software (IBM; Armonk, New York) and Comprehensive Meta-Analysis software version 3 (Biostat, Inc.), with p

Denosumab is a human monoclonal antibody (mAb) that specifically inhibits tumor-associated bone lysis through the RANKL pathway and has been used as neoadjuvant therapy for giant-cell tumor of bone (GCTB) in surgical as well as non-surgical cases. The purpose of this systematic review of the literature, therefore, is to investigate: (1) demographic characteristics of patients affected by GCTBs treated with denosumab and the clinical impact, as well as, possible complications associated with its use (2) oncological outcomes in terms of local recurrence rate (LRR) and development of lung metastasis, and (3) characteristics of its treatment effect in terms of clinical, radiological, and histological response. A systematic review of the literature was conducted using PubMed, EMBASE, and COCHRANE search including the following terms and Boolean operators: “Denosumab” AND “primary bone tumor”, “denosumab” AND “giant cell tumor”, “denosumab” AND “treatment”, and finally, “denosumab” AND “giant cell tumor” AND “treatment” since 2000. After applying inclusion and exclusion criteria, a total of 19 articles were included. The quality of the included studies was assessed using STROBE for the assessment of observational studies. A total of 1095 patients were included across all 19 studies. Across all the studies included, there were 615 females and 480 males. The mean patient age was 33.7 ± 8.3 years when starting the denosumab treatment. The pooled weighted local recurrence rate was 9% (95% CI 6–12%) and the pooled weighted metastases rate was 3% (95% CI 1–7%). The most common adverse event was fatigue and muscular pain. Radiologic response was estimated to occur in 66–100% of the patients. A significant reduction in pain under denosumab treatment was reported in seven studies and additional improvement in function and mobility was reported by several authors. Only two studies reported musculoskeletal tumor society (MSTS) scores which were better after denosumab treatment. The use of denosumab as an adjuvant treatment of GCTB has shown a positive but variable histological response with consistent radiological changes and several types of adverse effects. There is a positive clinical response in terms of pain relief with decrease on the morbidity of surgical procedures to be performed. Finally, oncological outcomes are disparate with neither effect on metastatic disease nor local recurrence rates. IV.

Infection and instability are the complications of prosthetic shoulder surgery of more difficult management. Instability builds up to half of the cases, while the fungal infection accounts for less than 1% of all and can cause severe damage to bone and soft tissue.In this case clinical fungal infection by Candida parapsilosis is presented in a shoulder hemiarthroplasty indicated by a fracture of the proximal humerus. He received surgical treatment in two-stages and administration of fluconazole for eight weeks prior to the second surgical time. In revision surgery was placed a reverse prosthesis as definitive treatment; however, the patient suffered several episodes of dislocation in the postoperative period; a second revision prosthetic surgery was necessary to use more stable components. During this surgery, we extracted samples that were analyzed, obtaining negative results for infection.Now after three years of follow-up, the patient is well, no limitations in their daily work and has a Constant Score of 50.5.We report our experience in this exceptional situation. We know, this is one of the first cases where the fungal infection and dislocation prosthetics in the same patient meet. This situation is a challenge for the surgeon, which has to treat complications two practically at the same time; we do not have scientific evidence to establish a criterion unified for the treatment of complications after surgery for revision of arthroplasty of the shoulder, especially in reverse or mega-denture prosthesis.La infección e inestabilidad se encuentran entre las complicaciones de más difícil manejo en la cirugía protésica de hombro. La inestabilidad acumula hasta la mitad de los casos, mientras que la infección por hongos representa menos de 1% del total de infecciones y pueden causar daño severo a nivel óseo y de partes blandas.En este caso clínico se presenta una infección fúngica por Candida parapsilosis en una hemiartroplastía de hombro indicada por una fractura de húmero proximal. Se dio tratamiento quirúrgico en dos tiempos y administración de fluconazol durante ocho semanas previo al segundo tiempo quirúrgico. En la revisión se colocó una prótesis reversa como tratamiento definitivo; sin embargo, el paciente sufrió varios episodios de luxación en el postoperatorio. Fue necesaria una segunda cirugía de revisión protésica para sustituir por componentes de mayor estabilidad. Durante la misma, se extrajeron muestras que fueron analizadas, obteniéndose resultados negativos para infección.Actualmente tras tres años de seguimiento, el paciente se encuentra bien, sin limitaciones en su labor diaria y tiene un Constant Score de 50.5.Reportamos nuestra experiencia en esta situación excepcional. A nuestro conocer, éste es uno de los primeros casos en los que la infección fúngica y la luxación protésica coinciden en un mismo paciente. Esta situación es un reto para el cirujano, el cual tiene que tratar las dos complicaciones prácticamente a la vez. No se dispone de una evidencia científica para establecer un criterio unificado para el tratamiento de las complicaciones tras cirugía de revisión de artroplastía de hombro, especialmente en la prótesis reversa o megaprótesis.
