La metodología de Planificación Centrada en la Persona (PCP) cada vez tiene mayor impacto en España. Comenzando desde las distintas legislaciones que regulan la atención a este colectivo en las diferentes autonomías y terminando en los centros que proveen este servicio. No obstante, existe escasa literatura internacional de estudios empíricos a grandes escalas que sitúen este enfoque metodológico en una posición relevante que garantice la eficacia de la PCP. El objetivo principal de este estudio es conocer el estado del uso de la metodología de PCP a través de estudios avalados empíricamente que sostengan tanto beneficios como limitaciones durante los últimos 10 años (2012-2022). Para ello, se ha realizado una revisión sistemática desde las directrices de PRISMA (2020), que incluye un total de 31 artículos. Como conclusión, se han descubierto más beneficios que limitaciones entre las que destacan las ventajas en su uso para las personas con discapacidad intelectual y del desarrollo y las mejoras de aspectos relacionados con la autodeterminación. No obstante, las limitaciones prevalecen por la falta de apoyos y recursos adecuados de las organizaciones para responder a una planificación centrada en la persona y la necesidad de formación de las personas implicadas en la elaboración de la PCP, lo que genera la incógnita de si se están realizando buenas prácticas en el uso de dicha metodología.

The methodology of Person Centered Planning (PCP) is having an increasing impact in Spain. Starting from the different legislations that regulate the attention to this group in the different autonomous regions and ending in the centers that provide this service. However, there is little international literature on large-scale empirical studies that place this methodological approach in a relevant position to guarantee the efficacy of PCP. The main objective of this study is to know the status of the use of PCP methodology through empirically supported studies that sustain both benefits and limitations during the last 10 years (2012-2022). For this purpose, a systematic review has been conducted since the PRISMA guidelines (2020), including a total of 31 articles. As a conclusion, more benefits than limitations have been found, among which the advantages in its use for people with intellectual and developmental disabilities and improvements in aspects related to self-determination stand out. However, limitations prevail due to the lack of adequate support and resources from organizations to respond to person-centered planning and the need for training of the people involved in the development of the PCP, which raises the question of whether good practices are being carried out in the use of this methodology.

El suicidio se ha convertido en un problema social y de salud pública a nivel mundial. En este sentido, la Terapia de Aceptación y Compromiso (ACT) podría ser eficaz en su abordaje, existiendo evidencia sobre la relación entre algunos de sus componentes y la conducta suicida. Así, el presente estudio tuvo por objetivo realizar una revisión sistemática sobre la eficacia de ACT en conducta suicida. Para ello se siguió el protocolo PRISMA, empleando las siguientes bases de datos: PsycInfo, PubMed, Scopus y PsicoDoc. Inicialmente se obtuvieron 108 publicaciones potencialmente relevantes, de las cuales, finalmente, 13 fueron incluidas en la revisión. La calidad de los estudios se analizó a través de un instrumento de evaluación de riesgo de sesgos. Como resultados, a nivel general se observaron disminuciones estadísticamente significativas en ideación suicida (IS) y factores de riesgo de suicidio. Además, algunos estudios señalaron relaciones estadísticamente significativas entre un aumento de flexibilidad psicológica y la disminución de IS. Si bien los datos apuntaron a una posible eficacia de ACT en la reducción de IS, es necesario llevar a cabo mayor número de estudios experimentales que contemplen la complejidad de la conducta suicida y exploren los procesos de cambio implicados.(AU)

La comorbilidad es más la regla que la excepción en salud mental y, sobre todo, en el caso de la ansiedad y la depresión. Los modelos transdiagnósticos estudian los procesos subyacentes para mejorar el tratamiento y la comprensión de la salud mental. Objetivo: Esta revisión sistemática busca evidencias sobre los factores de riesgo transdiagnósticos para la ansiedad y la depresión en la población clínica diagnosticada de estas condiciones psicopatológicas, analizando los diferentes tipos o categorías de factores identificados. Método: Se registró una revisión sistemática en PROSPERO (número de registro CRD42022370327) y se diseñó de acuerdo con las guías PRISMA-P. La calidad del estudio fue evaluada por dos revisores independientes con conocimiento del campo para reducir el posible sesgo. Resultados: Cincuenta y tres artículos fueron examinados y las variables transdiagnósticas fueron agrupadas en tres categorías: psicológicas, biológicas y socioculturales. Conclusiones: La categoría más estudiada fue la de variables psicológicas, en especial los procesos cognitivos, afecto negativo y neuroticismo, intolerancia a la incertidumbre, sensibilidad a la ansiedad. Los factores biológicos y socioculturales requieren más estudio para sustentar su enfoque transdiagnóstico.(AU)
Comorbidity is more the rule than the exception in mental health, specifically in the case of anxiety and depression. Transdiagnostic models studied the underlying processes to improve mental health treat-ment and understating. Objective:This systematic review searchs for evi-dence on transdiagnostic risk factors for anxiety and depression in the clin-ical population diagnosed with these psychopathological conditions, by an-alysing the different types or categories of factors identified.Methods:A sys-tematic review was registered in PROSPERO (registration number CRD42022370327) and was designed according to PRISMA-P guidelines. Two independent reviewers with field knowledge assessed the study quality to reduce bias.Results: Fifty-three articles were examined, and the transdi-agnostic variables were grouped into three categories: psychological, bio-logical, and sociocultural.Conclusions:The most studied category was that of psychological variables, especially cognitive processes, negative affect, and neuroticism, intolerance of uncertainty, anxiety sensitivity. Biological and sociocultural factors require more study to support their transdiagnos-tic approach.(AU)

INTRODUCTION: Revision total knee arthroplasty (rTKA) remains underexplored regarding patient-reported outcome measures (PROMs), particularly in terms of time to reach Minimal Clinically Important Difference (MCID). This study addresses this gap by comparing the time to achieve MCID between primary TKA (pTKA) and rTKA patients, providing valuable insights into their recovery trajectories. METHODS: A total of 8,266 TKAs (7,618 pTKA and 648 rTKA) were retrospectively studied in a multi-institutional arthroplasty registry. Patients who completed the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Physical, PROMIS Physical Function Short Form 10a (PF-10a), and Knee Injury and Osteoarthritis Outcome Score-Physical Function Short Form (KOOS-PS) questionnaires were identified by Current Procedural Terminology (CPT) codes. Survival curves with and without interval-censoring were utilized to evaluate the time to achieve MCID. RESULTS: Comparing the time to achieve MCID, rTKAs were significantly faster than pTKA for PROMIS Global Physical (3.5 versus 3.7 months, P = 0.004) and KOOS-PS (3.3 versus 4.2 months, P < 0.001), but similar for PROMIS PF-10a (4.4 versus 4.8 months, P = 0.057). Interval-censoring also showed similar trends with earlier times to achieve MCID for rTKAs for PROMIS Global Physical (0.6 to 0.61 versus 0.97 to 0.97 months, P = 0.009) and KOOS-PS (0.97 to 0.97 versus 1.47 to 1.47 months, P < 0.001), but not for PROMIS PF-10a (2.43 to 2.54 versus 1.90 to 1.91 months, P = 0.92). CONCLUSION: The present study revealed that the time to achieve MCID was faster in patients undergoing rTKA compared to those undergoing pTKA. These findings allow surgeons to reassure preoperative revision TKA patients that their recovery to a minimal clinically important difference postoperatively may be quicker than expected, especially when compared to their initial recovery after primary TKA.
RÉSUMÉ
BACKGROUND: Revision total hip arthroplasty (THA) can be complex, and assessing possible difficulties is important to predict the operative time. No simple score for predicting difficulties has been assessed prospectively. We therefore developed an original score for the pre-operative evaluation of extraction and reconstruction difficulties. The objectives of this prospective study were to (1) assess correlations between score values and operative time, (2) determine whether the score predicted the need for revision implants and/or filling material, (3) determine whether the score predicted intra-operative and post-operative complications, and (4) evaluate the inter-observer and intra-observer reproducibility of the score. HYPOTHESIS: The score is reproducible and correlates well with the operative time, thereby allowing prediction of this parameter before surgery. MATERIAL AND METHODS: A prospective study of 103 revision THA procedures performed between March 2018 and August 2023 was conducted. The primary outcome was operative time and the secondary outcomes were use of a revision implant, use of filling material, and intra-operative and post-operative complications. The score was determined by four observers to allow evaluation of inter-observer agreement. Intra-observer agreement was assessed by having one of the observers determine the score a second time after inclusion of the last patient. The score has a maximum value of 20 and allows classification of the procedure as very difficult, difficult, and moderately difficult. RESULTS: Mean operative time correlated with the score value: 136.0 ± 33.9 min in the very difficult group, 102.0 ± 34.8 min in the difficult group, and 75.4 ± 65.5 min in the moderately difficult group (p = 0.0002). The score predicted the use of a reinforcement ring (40 procedures: 12/17 [70%], 11/25 [44%], and 17/61 [28%] in the very difficult, difficult, and moderately difficult groups, respectively; p = 0.01) and of a long stem (20 procedures: 8/17 [47%], 7/25 [28%], and 5/61 [8%] patients in the very difficult, difficult, and moderately difficult groups, respectively; p < 0.001). The score did not predict the use of filling material (42 procedures: 10/17 [59%], 9/25 [36%], and 23/61 [37%] in the very difficult, difficult, and moderately difficult groups, respectively; p = 0.250). The score predicted both intra-operative complications (5/17 [29%], 4/25 [16%], and 4/61 [6%] procedures in the very difficult, difficult, and moderately difficult groups, respectively; p = 0.028) and post-operative complications (4/17 [23%], 0/25 [0%], and 6/61 [9%] in the very difficult, difficult, and moderately difficult groups, respectively; p = 0.15). Inter-observer agreement was strong according to Landis-Koch criteria, with kappa values ranging from 0.70 to 0.79 [0.57-0.90]. The kappa value for intra-observer agreement was 0.74 [0.63-0.85]. DISCUSSION: This score predicts surgical difficulties by adding criteria to bone destruction, in contrast to widely used classifications for revision THA. Moreover, the score is reproducible and predicts the operative time, thus potentially playing an important role during pre-operative planning. LEVEL OF EVIDENCE: IV; prospective observational non-comparative study.
RÉSUMÉ
Artificial urinary sphincters (AUS) are an effective treatment for male stress urinary incontinence (SUI). However, infection, erosion, mechanical failure, atrophy, and balloon deterioration cause device malfunction in approximately half of patients by 10 years after implantation. Many patients desire to regain urinary continence and require revision surgery (RS), including device removal and simultaneous or delayed implantation. Patients for whom RS is considered should be examined physically and by interview for signs of infection. Urethral erosion should be assessed using cystoscopy. If there is infection or erosion, all devices should be removed first, and a new device should be implanted several months later. During the RS, after strong adhesion around the urethra, transcorporal cuff implantation is a safe choice. Device removal and simultaneous implantation can be performed in the absence of infection or erosion. If a long time has passed since device implantation, the entire device should be replaced due to device aging and deterioration; however, if the time is short, only the defective component need be replaced. Intraoperative assessment of urethral health is necessary for device removal and implantation. If the urethra is healthy, a new cuff can be placed in the same position as the old cuff was removed from; however, if the urethra is unhealthy, the cuff can be implanted in a more proximal/distal position, or a transcorporal cuff implant may be chosen. This article reviews the literature on diagnostic and treatment strategies for recurrent SUI in male patients with AUS and proposes a flowchart for AUS revision.

BACKGROUND: UKA is a well-established treatment option for anteromedial osteoarthritis of the knee, resulting in superior functional outcomes but also higher revision rates than TKA. This study aimed to compare the outcomes of UKA, TKA, UKA converted to TKA using identical standard implants and revised TKA to support clinical decision-making. METHODS: In this study, we retrospectively examined 116 patients who underwent UKA, 77 patients who received TKA, 28 patients whose UKA was converted to TKA using identical standard implants, and 21 patients who had a one-stage revision of TKA. The mean age at operation was 66.5 years (39-90 years), with a mean BMI of 28.8 kg/m2 (17.4-58.8) and a mean follow-up period of four years (0.9-9.9 years). We assessed various PROMs, including Oxford Knee Score, UCLA score, KSS score, and a modified WOMAC-Score as well as patient satisfaction and ability to resume daily activities, work, and sports. RESULTS: The highest patient satisfaction was seen in the UKA. All scores were significantly higher for UKA than for TKA, converted UKA, and revised TKA. None of the scores showed a significant inferiority of converted UKA to TKA. In the case of revision, two scores showed significantly better results for converted UKA than for revised TKA. CONCLUSIONS: Our results indicated that patients initially treated with UKA did not have significantly worse functional outcomes after conversion to TKA, given the use of identical standard implants. This highlights the effectiveness of UKA as a therapeutic option with outcomes superior to those of primary TKA and the importance of a bone-sparing procedure. Conversely, revision TKA is linked to poorer functional outcomes compared to both primary arthroplasties.

Species of the ciliate class Heterotrichea Stein, 1859 are a cosmopolitan group of unicellular eukaryotic microorganisms, many of which have been widely used as models in various fields of research such as regenerative biology, functional ecology, environmental toxicology, and symbiotic behavior. However, species identification in the heterotrich family Condylostomatidae, especially the most species-rich and type genus Condylostoma Bory de Saint-Vincent, 1824, remains challenging due to incomplete original descriptions, few reliable distinguishing characters, and overlapping features between different species. This study presents an updated revision of Condylostoma and its related genus Condylostomides da Silva Neto, 1994 based on descriptions of five species, including nine populations collected from China, using both morphological and molecular methods. The main findings are as follows: (1) 43 nominal species and about 130 populations are reviewed, resulting in the recognition of 30 valid species of Condylostoma and eight valid species of Condylostomides; (2) keys, synonyms, biogeographic distributions and amended/improved diagnoses of all valid species are provided; (3) based on the available data, four new Condylostoma species (C. marinum sp. nov., C. petzi sp. nov., C. villeneuvei sp. nov., and C. microstomum sp. nov.), one new combination (Condylostomides minimus (Dragesco, 1954) comb. nov. & nom. corr.), and two corrected names (Condylostoma ancestrale Villeneuve-Brachon, 1940 nom. corr. and Condylostomides nigrus (Dragesco, 1960) nom. corr.) are suggested; (4) cryptic species are detected and proposed for the first time to form the Condylostoma curvum species complex; (5) three highly confusing Condylostoma species, C. kris, C. spatiosum, and C. minutum, are redefined for the first time based on modern taxonomic methods; (6) a 'flagship' species, Condylostomides coeruleus, is recorded for the first time from the continent of Asia, substantially expanding its biogeography; (7) ciliature adjacent to the distal end of the paroral membrane within the family Condylostomatidae is uniformly defined as frontal membranelles and is classified into three patterns according to the arrangement of kinetosomes, which serve as important key features.

RÉSUMÉ
The case presented in this article is one of recurrent left posterior periprosthetic knee dislocation (PPKD) in a patient with altered mental status (AMS). The patient, a 69-year-old female with a complex medical history including dementia, Ménière's syndrome, and left total knee arthroplasty, presented to the emergency department with AMS whereupon a left PPKD was discovered. Less than three weeks before this presentation, she sustained a left PPKD during a previous admission. During her current admission, she sustained yet another left PPKD after trials of closed reduction and immobilization. The patient eventually underwent a left cemented revision total knee arthroplasty with a hinged prosthesis. The implant was noted to be stable, and the patient had minimal pain postoperatively with no vascular or neurological injury. Upon outpatient follow-up, the patient reported doing well. There have been few documented cases of recurrent or chronic PPKD in individuals with AMS or restricted intellect. These comorbidities create a complex approach to diagnosing and treating the aforementioned orthopedic injury, and as this injury can have devastating consequences, quickly and effectively delivering diagnosis and treatment is vital. This case highlights the importance of early identification, risk factors, preoperative management, and appropriate operative course for patients with AMS and recurrent PPKDs.

Intertrochanteric (IT) femur fractures in the elderly population comprise a major part of geriatric trauma and fractures. There are various modalities of surgical management, ranging from intramedullary fixation and extramedullary fixation to even replacing the hip joint. Apart from the surgeon's choice, other factors, such as geriatric age, bone quality and osteoporosis, medical comorbidities, life expectancy, pre-operative ambulatory status, muscle strength, type and pattern of fracture, and mental health of the patient, play vital roles in determining the ideal modality of management and the long-term outcome. The present case is a 75-year-old lady who had an IT fracture due to a domestic fall, managed surgically with a proximal femoral nail anti-rotation Asia (PFNA2) for an unstable fracture. She presented with blade back-out on the 11th day postoperatively. The patient was investigated thoroughly, and infection was ruled out. She was managed by the removal of the nail, followed by a cemented calcar-replacing bipolar hemiarthroplasty for an unstable comminuted IT fracture. The patient was ambulatory with a walker by the seventh postoperative day and without a walker by the sixth week, and she was self-sufficient in her activities of daily living. Every geriatric IT fracture must be evaluated thoroughly for contributing factors, such as osteoporosis and fracture pattern, to predict outcomes, and a tailor-made strategy of surgical management and stepwise physiotherapy must be provided to the patient for the best results.
RÉSUMÉ
Background: Two-stage exchange arthroplasty remains the gold standard for treating chronic hip periprosthetic joint infections. However, controversy remains regarding the optimal spacer type, particularly among patients with increased dislocation risk. This study reports on the outcomes of articulating hip spacers utilizing a single constrained-liner design. Methods: All patients who underwent treatment for hip periprosthetic joint infection at a single institution were screened. Patients were included if they received an articulating spacer utilizing a constrained liner of a single manufacturer design. Indications for constrained liner, demographic variables, and surgical variables were recorded. Patients were assessed for dislocation and component loosening prior to the second stage or at the final follow-up if the second stage was not undertaken. Comparative analysis was performed. Results: Overall, 26 constrained liners were utilized in 25 patients. Indications for constrained liner included history of dislocation (n = 14), massive proximal femoral bone loss (n = 14), greater trochanteric deficiency (n = 12), and absent abductors (n = 7). Many patients had more than one indication. In total, 9 hips (34.6%) underwent a second stage at an average of 7.4 months, while 17 hips never underwent a second stage with an average follow-up of 27.6 months. One patient experienced failure of their constrained liner prior to the second stage due to pelvic discontinuity and massive acetabular bone loss. Conclusions: Utilization of a constrained liner as an articulating spacer is a viable option for patients at high risk of instability. Meticulous cement technique, appropriate component position, and implant selection are crucial in achieving successful outcomes.

Conservation literature addresses a broad spectrum of interdisciplinary questions and benefits. Conservation science benefits most when a diverse range of authors are represented, particularly those from countries where much conservation work is focused. In other disciplines, it is well known that barriers and biases exist in the academic publishing sphere, which can affect research dissemination and an author's career development. We used a discrete choice experiment to determine how 7 journal attributes affect authors' choices of where to publish in conservation. We targeted authors directly by contacting authors published in 18 target journals and indirectly via communication channels for conservation organizations. We only included respondents who had previously published in a conservation-related journal. We used a multinomial logit model and a latent class model to investigate preferences for all respondents and distinct subpopulations. We identified 3 demographic groups across 1038 respondents (older authors from predominantly middle-income countries, younger authors from predominantly middle-income countries, and younger authors from high-income countries) who had published in conservation journals. Each group exhibited different publishing preferences. Only 2 attributes showed a consistent response across groups: cost to publish negatively affected journal choice, including authors in high-income countries, and authors had a consistent preference for double-blind review. Authors from middle-income countries were willing to pay more for society-owned journals, unlike authors from high-income countries. Journals with a broad geographical scope that were open access and that had relatively high impact factors were preferred by 2 of the 3 demographic groups. However, journal scope and open access were more important in dictating journal choice than impact factor. Overall, different demographics had different preferences for journals and were limited in their selection based on attributes such as open access policy. However, the scarcity of respondents from low-income countries (2% of respondents) highlights the pervasive barriers to representation in conservation research. We recommend journals offer double-blind review, reduce or remove open access fees, investigate options for free editorial support, and better acknowledge the value of local-scale single-species studies. Academic societies in particular must reflect on how their journals support conservation and conservation professionals.
Comprensión de las elecciones de los autores en el entorno actual de publicaciones sobre la conservación Resumen La bibliografía sobre conservación aborda un amplio espectro de preguntas y beneficios interdisciplinarios. La mayor parte de ella representa una gama diversa de autores, sobre todo de países en los que se centra gran parte del trabajo de conservación. Es bien sabido que en otras disciplinas existen barreras y sesgos en el ámbito de la publicación académica que pueden afectar a la difusión de la investigación y al desarrollo de la carrera de un autor. Usamos un experimento de elección discreta para determinar cómo afectan siete atributos de las revistas sobre conservación en la elección de los autores sobre en cuál publicar. Nos dirigimos directamente a los autores y nos pusimos en contacto con quienes publicaban en 18 revistas objetivo e indirectamente a través de los canales de comunicación de las organizaciones de conservación. Sólo incluimos a los encuestados que habían publicado anteriormente en una revista relacionada con la conservación. Usamos un modelo logit multinominal y un modelo de clases latentes para investigar las preferencias de todos los encuestados y de las distintas subpoblaciones. Identificamos tres grupos demográficos entre los 1038 encuestados (autores de más edad de países con predominancia de ingresos medios, autores más jóvenes de países con predominancia de ingresos medios y autores más jóvenes de países con ingresos altos) que habían publicado en revistas de conservación. Cada grupo mostraba preferencias editoriales diferentes. Sólo dos atributos mostraron una respuesta coherente en todos los grupos: el costo de la publicación afectaba negativamente a la elección de la revista, incluidos los autores de países con ingresos altos, y los autores tenían una preferencia coherente por la revisión doble ciego. Los autores de países con ingresos medios están dispuestos a pagar más por las revistas pertenecientes a la sociedad, a diferencia de los autores de países de ingresos altos. Dos de los tres grupos demográficos prefieren las revistas de ámbito geográfico amplio, de acceso abierto y con un factor de impacto relativamente alto. Sin embargo, el alcance de la revista y el acceso abierto fueron más importantes que el factor de impacto. En general, los distintos grupos demográficos tenían preferencias diferentes en cuanto a las revistas y su selección se veía limitada por atributos como la política de acceso abierto. No obstante, la falta de encuestados procedentes de países con bajos ingresos (2% de los encuestados) destaca las barreras generalizadas para la representación en la investigación sobre conservación. Recomendamos que las revistas ofrezcan revisiones doble ciego, reduzcan o eliminen las tarifas de acceso abierto, investiguen opciones de apoyo editorial gratuito y reconozcan mejor el valor de los estudios de una sola especie a escala local. Las sociedades académicas, en particular, deben reflexionar sobre la forma en que sus revistas apoyan la conservación y a los profesionales de la conservación.
RÉSUMÉ
INTRODUCTION: Optimal bearing size in total hip arthroplasty (THA) has not been clearly ascertained, but large diameter ceramic balls may improve function and implant stability, with minimal concerns for wear. Delta ceramic-on-ceramic (COC) THA were stratified based on head diameter (32, 36 and 40 mm), aiming to assess: 1) survival rates, reasons for revision and hazard ratios for failure; 2) survival rates and hazard ratios for aseptic loosening, dislocation/primary instability, liner failure. MATERIALS AND METHODS: A regional arthroplasty registry was enquired about Delta COC THA performed for primary osteoarthritis, stratified by head size. 13,161 primary cementless THAs were included in the study, with a mean follow-up of 5.7 years (range: 0-17): 3980 (30.2%) 32 mm balls, 8327 (63.3%) 36 mm heads, 854 (6.5%) 40 mm heads. RESULTS: The three cohorts achieved similar survival rates (p = 0.99) and adjusted hazard ratios (p > 0.05). No revisions for head breakage or metallosis occurred. When revision for cup aseptic loosening was the endpoint, the survival rates of three cohorts (p = 0.08) and the adjusted hazard ratios (p > 0.05) were similar. The three cohorts achieved comparable survival rates when revision for dislocation/primary instability was the endpoint (p = 0.08). When the endpoint was revision for liner breakage, 32 mm cohort showed higher rates of revision (p = 0.01). No liner failure was detected in the 40 mm cohort. CONCLUSIONS: 32 mm, 36 mm and 40 mm provided similar 10-year survival rates in Delta COC THA. 40 mm heads emerged as safe options but did not lower the revisions for dislocations/primary instability. LEVEL OF EVIDENCE: IV (therapeutic study).
RÉSUMÉ
With the rising prevalence of shoulder arthroplasty, the incidence of revision shoulder arthroplasty is also increasing. The complexity of these revision procedures poses significant challenges, with bone loss being a critical factor impacting treatment outcomes. Addressing substantial humeral bone defects is crucial for ensuring implant stability and functionality. A comprehensive literature review was conducted using PubMed, Medline, and Google Scholar to identify existing classification systems for proximal humeral bone loss in the context of revision shoulder arthroplasty. The study assessed the advantages and limitations of these classifications, using this information to propose a new diagnostic and therapeutic algorithm. Several classification systems for proximal humeral bone loss were identified. McLendon et al. classify proximal humeral bone loss based on a 5-cm bone loss threshold and suggest an allograft prosthesis composite for losses exceeding this limit. Boileau's system stratifies bone loss into four types based on the extent of loss, with specific recommendations for each category. The PHAROS classification provides a detailed anatomical assessment but lacks quantitative precision. The proposed PHBL-SCORe system offers a novel algorithm incorporating preoperative radiographic measurements to determine the percentage of bone loss and guide treatment options. Proximal humeral bone loss presents significant challenges in revision shoulder arthroplasty, necessitating precise preoperative planning and classification to guide surgical intervention. Existing classification systems provide valuable frameworks but often rely on average population values, neglecting individual anatomical variations. The proposed PHBL-SCORe system offers a patient-specific approach, improving the accuracy of bone loss assessment and optimizing treatment strategies. Implementing this classification in clinical practice could enhance surgical outcomes and reduce complications associated with rRSA (revision Reverse Shoulder arthroplasty). Further studies are required to validate this algorithm and explore its long-term efficacy in diverse patient populations.

Peripheral nerve surgeries for compressive neuropathy in the upper extremity are generally successful. However, cases that either fail or have complications requiring revision surgery are challenging. During revision consideration, surgeons should perform a comprehensive preoperative workup to understand the etiology of the patient's symptoms and categorize symptoms as persistent, recurrent, or new in relation to the index procedure. Revision surgery often requires an open, extensile approach with additional procedures to optimize outcomes. Even with proper workup and treatment, clinical outcomes of revision surgeries are inferior compared to primary surgeries and patients should be well informed prior to undergoing such procedures.

BACKGROUND: The gold-standard treatment for Vancouver type B2 and B3 fractures is revision arthroplasty. This procedure can be prolonged and complex, posing challenges for patients with severe medical comorbidities and reduced physical status. Recently, osteosynthesis has been proposed as an alternative treatment for B2 periprosthetic femoral fractures (PFF) in frail patients, though its efficacy compared to revision arthroplasty has not been studied in detail. METHODS: A retrospective study was conducted from 2012 to 2022, comparing complications, mortality, length of stay, gait ability, hemoglobin decrease, and blood transfusion rates between 44 patients undergoing treatment for B2 or B3 PPF with either stem-revision arthroplasty (n = 28) or open reduction and internal fixation (ORIF) with plates and screws (n = 16). RESULTS: The results showed no significant differences in mortality, complications, hemoglobin decrease, blood transfusion rate, or length of stay between the two groups. In the stem-revision group, 11 patients (60.7 %) experienced a medical complication, while 7 patients (43.8 %) in the ORIF group had complications (p = 0.778). The mortality rate within the first year post-surgery was 17.9 % (5 patients) in the stem-revision group compared to 18.8 % (3 patients) in the ORIF group (p = 0.943). Surgical complications occurred in 2 patients (7.1 %) in the stem-revision group and in 4 patients (25 %) in the ORIF group (p = 0.101). Blood transfusions were required in 17 patients (60.7 %) in the stem-revision group and in 8 patients (50 %) in the ORIF group (p = 0.829). CONCLUSIONS: This study suggests that ORIF is an acceptable treatment option for patients with B2 or B3 PFF, especially for those with severe medical comorbidities and reduced physical status who may not tolerate revision arthroplasty. However, further research with larger sample sizes and longer follow-up periods is needed to confirm these findings. LEVEL OF EVIDENCE: IV.
RÉSUMÉ
INTRODUCTION: The increasing prevalence of primary hip arthroplasty has led to a parallel rise in revision cases. Femoral revision often entails compromised bone integrity, requiring consideration of various solutions for optimal reconstructive options. Despite technological advancements, there is limited evidence on the clinical outcomes of the latest modular revision stems. This study aimed to evaluate the clinical outcomes and survival rates of next generation uncemented modular revision stem in patients undergoing hip revision surgery. MATERIALS AND METHODS: This retrospective single-center study assessed the survival and failure causes of a specific uncemented modular stem in 48 patients undergoing hip revision surgery between 2012 and 2022. Data included preoperative parameters, surgical details, and postoperative outcomes measured through clinical and radiographic assessments. Forty-eight patients (25 males, 23 females; mean age 72 years) were included, with a mean Charlson Comorbidity Index of 5. Preoperative diagnoses varied, with periprosthetic joint infection (PJI) being the most common (45.8%), followed by periprosthetic fractures (27.1%). Partial revisions occurred in 60.4%, total revisions in 39.6%. According to Paprosky classification of femoral bone loss, type II and III were the most represented, respectively 35.4% and 50%. RESULTS: At a mean follow-up of 4.6 years, stem survival was 92.5%. Complications (20%) included dislocation, PJI, fracture, and loosening; the overall reoperation rate was 12.5%. The SF-12 physical score was 43.6, while the mental score was 51.1. The HOOS score was 71.8, and the HHS score was 71.4. Radiographic analysis identified nonprogressive osteolysis in 15.1% of patients. CONCLUSIONS: This study on this uncemented modular revision stem demonstrated favorable outcomes in an elder fragile population with moderate to severe femoral bone loss. The implant's modularity provides versatility in addressing various defects, without any implant breakage observed during the study period. Literature comparison highlighted similar outcomes despite sample size differences. The promising results warrant continued investigation into the long-term survivorship of this modular stem system.
RÉSUMÉ
Background: Nerve injury following total hip arthroplasty (THA) is a rare but serious adverse event. While prior studies have reported risk factors for nerve injury related to THA, they are limited to institutional data or small sample sizes. The current study aimed to leverage a large, national database to assess independent risk factors for sustaining nerve injury with THA. Methods: The 2010-2021 PearlDiver M157 database was queried for adult THA cases. Those with nerve injury within 90 days of THA were identified. Patient age, sex, body mass index (BMI), Elixhauser comorbidity index (ECI), fracture indication, and surgery type (index vs revision) were assessed for correlation with nerve injury by multivariate analyses. Results: Out of 750,695 THAs, 2659 (0.35%) had nerve injuries. Multivariate analysis revealed independent predictors of nerve injury in decreasing odds ratio (OR) order to include: revision procedure (OR: 2.13), female sex (OR 1.35), ECI (ECI 1-2 [OR 1.27], ECI 3-4 [OR 1.43], and ECI ≥5 [OR 1.59]) and age (OR 1.02 per decade decrease) (P < .05 for each). Pertinent negatives by multivariate analysis included underweight BMI (<20), and fracture indication. Individuals with morbidly obese BMI status (≥35) had a decreased risk of nerve injury (OR 0.84, P = .019). Conclusions: THA-related nerve injury was found to be low at 0.35%. Factors independently associated with this adverse outcome were defined, of which the greatest risk was seen in revision procedures. These risk factors, derived from the largest cohort to date, may be helpful for risk stratification and patient counseling.

Background: Outcomes in patients with relatively high His-bundle (HB) capture thresholds at implantation are unknown. This study aimed to compare changes in the HB capture threshold and prognosis between patients with a relatively high threshold and those with a low threshold. Methods and Results: Forty-nine patients who underwent permanent HB pacing (HBP) were divided into two groups: low (<1.25 V at 1.0 ms; n=35) and high (1.25-2.49 V; n=14) baseline HB capture threshold groups. The HB capture threshold was evaluated at implantation, and after 1 week, 1, 3, and 6 months, and every 6 months thereafter. HB capture threshold rise was defined as threshold rise ≥1.0 V at 1.0 ms compared with implantation measures. We compared outcomes between the groups. During a mean follow-up period of 34.6 months, the high-threshold group showed a trend toward a higher incidence of HB capture threshold of ≥2.5 V (50% vs. 14%; P=0.023), HBP abandonment (29% vs. 8.6%; P=0.091), lead revision (21% vs. 2.9%; P=0.065), and clinical events (all-cause death, heart failure hospitalization, and new-onset or progression of atrial fibrillation; 50% vs. 23%; P=0.089) than the low-threshold group. A baseline HB capture threshold of ≥1.25V was an independent predictor of clinical events. Conclusions: A relatively high HB capture threshold is associated with increased risk of HBP abandonment, lead revision, and poor clinical outcomes.
