RESUMEN

Background: The tuna industry is one of the most essential sectors in global food production. Nevertheless, commercial meat known as "tuna loin" holds the utmost significance in producing and marketing its various products. Regrettably, fractions like tail and head meat have been overlooked and wasted due to their comparatively lower commercial value. Despite possessing notable technological value, this meat is typically reutilized into animal feed through flour production, missing the chance to create alternative high-value food products. Objective: This study aimed to develop and evaluate the sausages produced with the underutilized cuts of tuna (tail and head meat). Methods: The tuna utilized were Big-eye (Thunus obesus) and Skip-jack (Katsuwonus pelamis lineaus). Three (3) different types of sausages were formulated using 100% of Big-eye (BE), 100% of Skip-jack (SJ) tuna meat, and 100% of beef/pork meat (Control). The sausage pH changes during storage at 4 ± 1oC were analyzed and compared with the control. Proximal, microbiological, and sensory characteristics were evaluated. Results: The pH of sausages showed that the values tended to decrease in control, while this value increased in two types of tuna. The formulated tuna sausages yielded 72% moisture, 18% protein, 4.1% lipid, 0.4% ash, 0.4 % fiber, and 4.5% carbohydrates. Sensory attributes showed excellent acceptance regarding color, smell, flavor, and texture. Overall acceptability was qualified as "liked," and the acceptability index ranged from 76% to 86%. During the refrigeration storage, the microbiological analyses indicated that the total coliform count was < 3 CFU/g. Escherichia coli, Staphylococcus aureus, and mesophilic aerobic bacteria in tuna sausage showed absence during 24 days of storage. Conclusion: Using tuna tail and head meat enabled the development of gel-type emulsified products (sausages) that exhibited good nutritional, sensory, and microbiological quality


Antecedentes: La industria atunera se erige como uno de los sectores más importantes en la producción mundial de alimentos. Sin embargo, entre sus diversos productos, la carne comercial conocida como "lomo de atún" ostenta la mayor importancia tanto en su producción como en su comercialización. Lamentablemente, fracciones de carne provenientes de la cola y la cabeza se han desperdiciado debido a su reducido valor comercial. A pesar de poseer un notable valor tecnológico, esta carne normalmente es utilizada en la alimentación animal mediante la producción de harina, perdiendo la oportunidad de desarrollar productos alimenticios alternativos con alto valor nutricional. Objetivo: Este estudio tuvo como objetivo desarrollar y evaluar salchichas producidas con carne subutilizada de atún (carne de cola y cabeza). Métodos: Las especies de atún utilizadas fueron Big-eye (Thunus obesus) and Skip-jack (Katsuwonus pelamis lineaus). Se formularon tres (3) tipos diferentes de salchichas usando 100 % de carne de atún Big-eye (BE), 100 % de Skip-jack (SJ) y 100 % de carne de res/cerdo (Control). Se analizaron los cambios de pH en las salchichas durante el almacenamiento a 4 ± 1 oC y se compararon con el Control. También se evaluaron la composición proximal, calidad microbiológica y atributos sensoriales. Resultados: El pH mostró que los valores tendieron a disminuir en relación a la muestra Control, mientras que este valor aumentó en los dos tipos de salchicha con carne de atún. Las salchichas con carne de atún mostraron un 72 % de humedad, 18 % de proteína, 4,1 % de lípidos, 0,4 % de ceniza, 0,4 % de fibra, 4,5 % de carbohidratos. Los atributos sensoriales mostraron buena aceptabilidad de los parámetros de color, olor, sabor y textura. La aceptabilidad general se calificó como "me gusta" y el índice de aceptabilidad osciló entre el 76 % y el 86 %. Durante el periodo de almacenamiento en refrigeración, los análisis microbiológicos indicaron que el recuento de coliformes totales fue < 3 UFC/g. No se evidenció la presencia de Escherichia coli, Staphylococcus aureus y bacterias aerobias mesófilas durante 24 días de almacenamiento. Conclusión: El aprovechamiento de la carne de la cola y cabeza del atún permitió desarrollar productos emulsionados tipo gel (embutidos) que exhibieron buena calidad nutricional, sensorial y microbiológica.

RESUMEN

OBJECTIVE@#To review the advancement made in the understanding of valgus impacted proximal humeral fracture (PHF).@*METHODS@#The domestic and foreign literature about the valgus impacted PHF was extensively reviewed and the definition, classification, pathological features, and treatment of valgus impacted PHFs were summarized.@*RESULTS@#PHF with a neck shaft angle ≥160° is recognized as a valgus impacted PHF characterized by the preservation of the medial epiphyseal region of the humeral head, which contributes to maintenance of the medial periosteum's integrity after fracture and reduces the occurrence of avascular necrosis. Therefore, the valgus impacted PHF has a better prognosis when compared to other complex PHFs. The Neer classification designates it as a three- or four-part fracture, while the AO/Association for the Study of Internal Fixation (AO/ASIF) categorizes it as type C (C1.1). In the management of the valgus impacted PHF, the selection between conservative and surgical approaches is contingent upon the patient's age and the extent of fracture displacement. While conservative treatment offers the advantage of being non-invasive, it is accompanied by limitations such as the inability to achieve anatomical reduction and the potential for multiple complications. Surgical treatment includes open reduction combined with steel wire or locking plate and/or non-absorbable suture, transosseous suture technology, and shoulder replacement. Surgeons must adopt personalized treatment strategies for each patient with a valgus impacted PHF. Minimally invasive surgery helps to preserve blood supply to the humeral head, mitigate the likelihood of avascular necrosis, and reduce postoperative complications of bone and soft tissue. For elderly patients with severe comminuted and displaced fractures, osteoporosis, and unsuitable internal fixation, shoulder joint replacement is the best treatment option.@*CONCLUSION@#Currently, there has been some advancement in the classification, vascular supply, and management of valgus impacted PHF. Nevertheless, further research is imperative to assess the clinical safety, biomechanical stability, and indication of minimally invasive technology.

RESUMEN

Este artículo representa una revisión actual y completa de las fuerzas biomecánicas en el fémur proximal, tal como Koch presentó preliminarmente en su trabajo sobre la arquitectura ósea del fémur proximal. Su trabajo reflejó en la complejidad de las fracturas de fémur proximal y el manejo de las fracturas subtrocantéricas en paralelo con su clasificación y con la evolución de implantes. Existen múltiples formas de clasificar las fracturas subtrocantéricas; sin embargo, no existe un sistema de clasificación que se utilice para guiar el manejo quirúrgico. El tratamiento de las fracturas subtrocantéricas es la fijación quirúrgica, que implica el enclavado endomedular y placas de osteosíntesis. El tratamiento estándar es el enclavado endomedular con opciones de enclavado anterógrado y retrógrado. Aunque el enclavado anterógrado presenta una ventaja debido a las fuerzas deformantes, el enclavado retrógrado de las fracturas de fémur proximal ofrece menos tiempo quirúrgico y pérdida de sangre. Se han informado resultados similares entre los dos métodos. La toma de decisiones cuando se contempla el enclavado anterógrado versus retrógrado para las fracturas de fémur se basa principalmente en la constitución corporal y las lesiones asociadas, y no en la distancia de la fractura del fémur proximal a la región trocantérica


This article presents a current and comprehensive review of the biomechanical forces on the proximal femur, as preliminarily presented by Koch's cornerstone work on the bone architecture of the proximal femur. His work reflected on the complexity of proximal femur fractures and subtrochanteric fracture management in parallel with implant evolution and classification. Multiple ways of classifying subtrochanteric fractures exist, however, there is not one classification system that is used to guide operative management. The management of subtrochanteric fractures is surgical fixation which involves intramedullary nailing and plating (e.g., fixed angle and locking). The gold standard management is intramedullary nailing with antegrade and retrograde nail options. Though antegrade nailing presents an advantage due to the deforming forces, retrograde nailing of proximal femur fractures offers less operative time and blood loss. Similar outcomes have been reported between the two methods. Decision making when contemplating antegrade versus retrograde nailing for femur fractures is mostly driven by body habitus and associated injuries, and not by fracture distance of the proximal femur to the trochanteric region

RESUMEN

Introduction: Osteoarthritis of the knee is a common musculoskeletal diseases affecting a major population in India. It can impact the individual's functions and activities of daily living. Total knee arthroplasty may raise controversy when treating the younger, athletic patient with arthritis. Arthroscopic debridement, high tibial osteotomy, unicondylar knee arthroplasty, and total knee arthroplasty allow younger patients to maintain an active, healthy lifestyle but can take a longer time to rehabilitate. PFO could be used as an alternative procedure. The Proximal Fibular Osteotomy, which provides immediate short term relief in cases with medial compartment osteoarthritis. Resecting a segment of fibula, loosens the lateral side allowing the upper tibia to settle into a more favorable lateral alignment, shifting the mechanical axis towards neutral or valgus. Aims & objectives: Ÿ To assess the functional, clinical and radiological outcome of proximal fibular osteotomy in grade 2 and 3 OA of knee and followed up for 1 year. Ÿ The clinical and functional outcome is accessed by Knee Society Score and VAS observed pre-op , post-op ,3 months ,6 months and 12 months. Ÿ The improvement in radiology is accessed using change in the medial joint space improvements in CP angle, change in the ratio of medial joint space to lateral joint space observed pre-op and post-op Methodology: The patients selected had grade 2 and 3 Osteoarthritis of knee according to Kellgren Lawrence classification between the age groups 20yrs-80yrs and are admitted to RajaRajeswari Medical College and Hospital, Bangalore. The Sample Size is 30 and is calculated based on previous studies as well as approximate availability of number of cases in the above mentioned duration satisfying inclusion and exclusion criteria. Clinical, functional and radiological outcome were used, Results were calculated using Knee Society Scoring Scale score. This study Conclusion: suggested that Proximal Fibular Osteotomy is an alternative procedure that can be used to treat medial compartment knee Osteoarthritis, if the patients are selected carefully. Patients followed up for one year showed a significant improvement in radiological, clinical and functional outcomes and thereby is an effective method of treatment in younger patients with Grade 2 and Grade 3 Osteoarthritis with an average BMI of 26.2.

RESUMEN

Background: Proximal Femoral Nail (PFN) is a surgical technique used to treat unstable intertrochanteric fractures, which are fractures that occur in the upper portion of the thigh bone (femur). The procedure involves using a nail-like device that is inserted into the femur and secured in place with screws to stabilize the fracture and promote healing. It is a commonly used treatment option for this type of fracture and can lead to good outcomes in most cases. The aim of the study was to observe the outcome of Unstable Intertrochanteric fracture by Proximal Femoral Nail (PFN). Material & Methods: This prospective observational study was conducted at the Department of Orthopedics, National Institute of Traumatology and Orthopedic Rehabilitation (NITOR), Dhaka, Bangladesh. The study duration was 2 years, from July 2017 to June 2019. A total of 34 cases were included in the study sing purposive sampling (non-randomized) according to availability of the patients and considering inclusion and exclusion criteria. Results: The participants’ age range was 16-90, with a mean of 56.91 ± 17.76. Most (35.29%) were 61-75 years old. 61.76% were female and 38.24% were male. 50% were housewives, 14.71% ex-service holders, 14.71% service holders, 11.76% businessmen, 5.88% students, and 2.94% farmers. The leading cause of injury was falls on slippery ground (55.88%), followed by motor vehicle injuries (44.12%). 70.59% of injuries occurred on the right side and 29.41% on the left. 76% had Kyle Type III fractures, 24% had type IV. 85.29% had open reduction, 14.71% had closed reduction. The mean duration of injury to operation was 15.59 days and the mean hospital stay was 19.15 days. 70.59% had no complications and 55.88% reported no pain at last follow-up. 58.82% had a good Harris hip score and 58.82% had excellent outcomes by final follow-up. Conclusion: The majority of patients in this study were in the 61-75 age range and female, with the most common cause of injury being falls on slippery ground. The most common fracture type was Kyle type IV, with a major portion of cases requiring open reduction. The rate of complications was relatively low, and the functional outcomes were acceptable and comparable to other studies. The duration of injury to operation and hospital stay were slightly longer than other studies, likely due to the busy nature of the study location. Overall, the Proximal Femoral Nail is a safe and effective treatment option for unstable proximal femoral fractures.

RESUMEN

Introduction: Proximal lesions that exceed the cement enamel limit (ACE) under the gingival margin complicate impressions and the adhesive technique. Compare the magnitude of micro infiltration between conventional resin and bulk fill resin in the cervical margin relocation technique. Materials and Methods: 48 samples of human teeth re-ceived two preparations: occluso-mesial (OM) and occluso-distal (OD) under LAC; first they received the cervical margin relocation technique (RMC) with bulk fill and conventional resin; then restored with semi-direct resinous inlays. Sample analysis: immersion in 50% colloidal silver nitrate solution, 24 hours, 37°C and cut mesiodistally. Observed under a stereoscopic magnifying glass to assess dye penetration and digitally photographed, analyzed with "Image J" software. Results: Sample of 96 cavities in two groups of 48 units; control group restored with conventional resin with incremental technique and study group restored with bulk fill resin, mono-incremental technique. Probabilistic sampling. No statistically significant diffe-rences in percentage of microinfiltrated area between Filtek™ Z250™ and Filtek™ Bulk Fill™ (p-value= 0.68). Discussion: Various studies show that the presence of marginal microinfiltration exist independent of: restorative technique, consistency, adhesive mechanism and polyme-rization technique. The research carried out is no exception, observing a similar degree for both systems. Conclusions: Results allow us to conclude that conventi-onal resin and bulk fill resin did not show significant differences in microleakage percentages for the RMC technique. Outside the study framework, bulk fill resins would have comparative advantages; better behavior against light in depths greater than 2 mm, less sensitivity to the "C" factor, and less clinical time.


Introducción: Las lesiones proximales que superan el límite cemento esmalte (ACE) por debajo del margen gingival complican las impresiones y la técnica adhesiva. Comparar la magnitud de la microinfiltración entre la resina convencional y la resina de relleno en la técnica de reubicación del margen cervical. Materiales y Métodos: 48 muestras de dientes humanos recibieron dos preparaciones: ocluso-mesial (OM) y ocluso-distal (OD) bajo LAC, primero recibieron la técnica de reubicación del margen cervical (RMC) con relleno en bloque y resina convencional; luego restaurado con incrustaciones resinosas semidirectas. Análisis de la muestra: inmersión en solución de nitrato de plata coloidal al 50%, 24 horas, 37°C y corte mesiodistal. Observado bajo una lupa estereoscópica para evaluar la penetración del tinte y fotografiado digitalmente, analizado con el software "Image J". Resultados: Muestra de 96 cavidades en dos grupos de 48 unidades; grupo control restaurado con resina convencional con técnica incremental y grupo estudio restaurado con resina bulk fill, técnica mono-incremental. Muestreo probabilístico. No hubo diferencias estadísticamente significativas en el porcentaje de área microinfiltrada entre Filtek™ Z250™ y Filtek™ Bulk Fill™ (p-value = 0,68) Discusión: Diversos estudios evidencian presencia de microinfiltración marginal, independiente de técnica restauradora, consistencia, mecanismo adhesivo y técnica polimerizadora. La investigación realizada no es excepción, observándose grado similar para ambos sistemas. Conclusiones: Los resultados permiten concluir que resina convencional y resina bulk fill no presentaron diferencias significativas en porcentajes de microinfiltración para técnica RMC. Fuera del marco del estudio, resinas bulk fill tendrían ventajas comparativas; mejor comportamiento frente a la luz en profundidades superiores a 2 mm, menor sensibilidad al factor "C", y menor tiempo clínico.

Introducción: Las fracturas intertrocantéricas del extremo proximal del fémur constituyen el grupo nosológico con mayor morbilidad y mortalidad de las lesiones traumáticas del esqueleto. Objetivo: Evaluar la reducción, la colocación del implante y el tiempo de consolidación. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo de 114 pacientes con diagnóstico de fracturas del extremo proximal del fémur tratadas con clavo femoral proximal, y un seguimiento posoperatorio de un año. Resultados: Se alcanzó un resultado clínico funcional de excelente a bueno en el 82,4 % de los casos. Se evidenciaron signos radiológicos de consolidación en un promedio de 4,2 meses en la mayor parte de la muestra. Conclusiones: La pérdida de la fijación constituyó la complicación más frecuente; por tanto, se considera que el enclavado femoral proximal ofrece buenos resultados en el tratamiento de fracturas intertrocantéricas inestables del fémur.


Introduction: Intertrochanteric fractures of the proximal end of the femur constitute the nosological group with the highest morbidity and mortality of traumatic skeletal injuries. Objective: To evaluate reduction, implant placement and consolidation time. Methods: A descriptive, longitudinal and prospective study was carried out in 114 patients with diagnosis of fractures of the proximal end of the femur treated with proximal femoral nailing, and a one-year postoperative follow-up. Results: A functional clinical result from excellent to good was achieved in 82.4% of the cases. Radiological signs of consolidation were evidenced in an average of 4.2 months in most of the sample. Conclusions: Loss of fixation was the most frequent complication; therefore, proximal femoral nailing is considered to offer good results in the treatment of unstable intertrochanteric fractures of the femur.

RESUMEN

Background: Intertrochanteric fractures are among the frequently seen fractures in the elderly population. Treating these fractures is very challenging considering the fact that the quality of bone is poor and highly osteoporotic. The high failure rates with dynamic hip screw (DHS) especially in unstable fractures lead to the development of intramedullary devices such as proximal femoral nail (PFN) which has got multiple advantages over DHS. Materials and Methods: This prospective study included 30 patients above the age group of 60 years with unstable intertrochanteric fractures conducted in a tertiary institute between February 2021 and June 2022. Results were analyzed clinically and radiologically using the Modified Harris hip score. Results: Patients’ age group was 61–85 years with a mean age of 69 years, comprising 63% female and 37% male. The average Harris hip score was 83.76 at 24 weeks’ follow-up with 33.33% excellent, 56.66% good, 3.33% fair, and 6.67% poor. Postoperative complications included revision surgery in two patients, superficial infection in one patient, Z effect in one patient, peri-implant fracture in one patient. Conclusion: Treatment with PFN for unstable intertrochanteric fracture has the advantages of closed reduction, less tissue damage, early rehabilitation, and return to work. Osteosynthesis with short PFN resulted in good-to-excellent functional and radiological outcomes.

RESUMEN

Background: Many fish hybrids (i.e., obtained by crossing two species) are produced rather than pure species because of their better growth rate and/or acceptance of formulated feed. However, few studies evaluate and compare their meats and acceptance, including, e.g., for the Amazon hybrid sorubim (Pseudoplatystoma reticulatum x Leiarius marmoratus) and the real hybrid sorubim (Pseudoplatystoma corruscans x L. marmoratus). Objective: Thus, this work aimed to evaluate the physical, chemical, microbiological, and sensory characteristics of fillets from the Amazon and real hybrid sorubins. Method:Proximate composition, instrumental color, water holding capacity, cooking losses, and shear force were measured.Microbiological analyses of the fillets were carried out for Salmonellasp. and Staphylococcusaureus to ensure food safety during sensory analysis. Results: Fillets presented excellent quality, classified in category A (lipids below 5% and proteins between 15 and 20%). There was no significant difference (p>0.05) between the evaluated fillets for several parameters: the average water holding capacities were 33.72 and 34.67%, the cooking losses were 14.93 and 13.41%, the shear forces were 2.21 and 1.74 kgf, and the luminosities were 49.61 and 45.04 for the fillets of Amazonian hybrid sorubim and real hybrid sorubim, respectively. Discussion: There was an evident relationship between water-holding capacities and shear forces. Amazonian hybrid sorubim fillets presented lower intensity of red. However, there was no sensory difference between the hybrids, and both had an acceptance rate above 80%. Conclusion: The hybridization does not alter the characteristics of the fish fillets


Antecedentes: Muchos híbridos de peces (i.e., obtenidos al cruzar dos especies) se producen en lugar de especies puras debido a su mejor tasa de crecimiento y/o aceptación de alimentos formulados. Sin embargo, pocos estudios evalúan y comparan sus carnes y aceptación, incluyendo, p. ej., para lo surubí híbrido amazónico (Pseudoplatystoma reticulatum x Leiarius marmoratus) y lo surubí híbrido real (Pseudoplatystoma corruscans x L. marmoratus). Objetivo: Así, el objetivo de este trabajo fue evaluar las características físicas, químicas, microbiológicas y sensoriales de filetes sorubines híbridos amazónico y real. Método: Se midió composición proximal, color instrumental, capacidad de retención de agua, pierdas por cocción y fuerza de corte. Se realizaron análisis microbiológicos de los filetes para Salmonella sp. y Staphylococcus aureus para garantizar la seguridad alimentaria durante el análisis sensorial. Resultados: Los filetes presentaron una excelente calidad, siendo clasificados en la categoría A (lípidos por debajo del 5% y proteínas entre 15 y 20%). No hubo diferencia significativa (p>0.05) entre los filetes evaluados para varios parámetros: las capacidades de retención de agua fueron 33.72 y 34.67%, las pierdas por cocción fueron 14.93 y 13.41%, las fuerzas de corte fueron 2.21 y 1.74 kgf y las luminosidades fueron 49.61 y 45.04 para los filetes de sorubim híbrido amazónico y sorubim híbrido real, respectivamente. Discusión: Hubo una relación evidente entre las capacidades de retención de agua y las fuerzas de corte. Los filetes de sorubim híbridos amazónicos presentaron menor intensidad de rojo. Sin embargo, no hubo diferencia sensorial entre los híbridos, y ambos tuvieron una tasa de aceptación superior al 80%. Conclusión: La hibridación no altera las características de los filetes de pescado

RESUMEN

Objective To analyze and describe the morphological characteristics of the proximal origin of the biceps brachii, and measure the anatomical data of its tendons, so as to provide references for related clinical applications of the biceps brachii. Methods Six adult shoulder specimens (4 on the left and 2 on the right) were dissected to observe the origin, morphology, and course of the biceps brachii tendon and its adjacent relationship with the coracobrachialis muscle, musculocutaneous nerve and other structures. And then the length, width, and thickness of the biceps tendon were measured. Results The origin of the short head of biceps consisted of muscle fibers attaching directly to the tip of the coracoid process, with a thin, tendinous aponeurosis covering its anterior surface, rather than a true tendon as previously described. The mean of length,widths and thickness of the short head of biceps were (107.7±9.6) mm,(20.0±1.5)mm and (5.8±2.0)mm. Conclusion The short head of the biceps brachii is directly from the coracoid process with muscle fibers.

RESUMEN

Purpose:This study aimed to clarify the conditions necessary for patients with a proximal femoral fracture in the convalescent ward to return home using a decision tree analysis. This study included 181 patients who were discharged from the convalescent ward between January 2018 and June 2022.Methods:Patients divided into two groups:home vs. facility according to the outcome. Basic characteristics, FIM at admission, and MMSE at admission were compared using the unpaired t-test, χ2 test, and Mann-Whitney U test, and a decision tree analysis was performed.Results:The decision tree analysis based on functional independence measures (FIM) on admission and toileting activities, etc. found that discharge was difficult (return home rate:9.7%-28.6%) when the problem-solving aspect of the FIM on admission was less than 4 points.Conclusion:When discharging patients with a proximal femoral fracture from the hospital, it is important to consider a combination of problem-solving in the admission FIM and toileting activities.

RESUMEN

@#Introduction: Proximal tibial plateau fractures are one of the major problems in orthopaedic surgery and are associated with high complication rates. Intra-articular proximal tibia plateau fractures represent approximately 1% of fractures in adults. Various modalities of proximal tibial plateau fracture management have been considered, ranging from simple external fixators in impending compartment syndrome to periarticular proximal tibia plates and inter-locking nails with poller screws. Purpose of this study is to determine clinical outcomes of proximal tibial plateau fractures treated with plate. Materials and methods: We did this study of proximal tibial plateau fracture according to Schatzker’s classification treated with proximal tibial periarticular plates in 53 patients prospectively admitted at the author’s institute from June 2018 to May 2020 with follow-up period of 6 months. Results: In our study, the average knee score was 89.30 (ranging from 79 to 93) and functional knee score was 97.92 (ranging from 75 to 100). Fifty-one (51) patients (96.23%) showed excellent results and 2 patients (3.77%) showed good results according to Knee Society Score, which suggest that internal fixation of proximal tibia plateau fracture with plating provides better results. Out of 53 patients, 9 patients had post-operative complications. Average radiological union was seen at 14 weeks. Conclusion: Locking compression plate in proximal tibia plateau fractures act as a good biological fixation provide stable fixation, articular reduction and limb alignment even in difficult fracture situations. Fixation of proximal tibia plateau fractures with plate gives excellent to good knee society score, with satisfactory functional and radiological outcome.

OBJECTIVE@#To measure and compare medial proximal tibial angle (MPTA) of lower limbs under different axial rotation angles(neutral position, 30° internal rotation, 30° external rotation) on the load position radiographs, and explore changes and significance of MPTA measured within and between groups of tibia at different axial rotation positions.@*METHODS@#From January 2018 to December 2018, 40 patients with knee osteoarthritis (KOA) were selected, with a total of 80 limbs, including 12 males and 28 females, aged from 29 to 73 years old with an average of (59.6±12.7) years old. Full length radiographs of the lower limbs were taken on neutral tibia position, 30° internal rotation and 30° external rotation, respectively. MPTA was measured and the results were compared between groups and within groups.@*RESULTS@#MPTA measured on the left lower extremity of neutral tibia, 30° internal rotation and 30° external rotation were (86.08±2.48) °, (88.62±2.94) ° and (83.47±3.10) °, respectively. MPTA measured on the right lower limb were (86.87±1.97) °, (89.02±2.39) ° and (83.80±2.77) °, respectively, and there were no significant difference in MPTA measured between rotation angle group (P>0.05). While there were statistical difference in MPTA on the same limb between groups (P<0.05). On 30° internal rotation, MPTA of left and right lower limbs increased by (2.54±1.74) ° and (2.15±1.78) ° compared with tibia neutral position. On 30° external rotation, MPTA of left and right lower limbs decreased (2.61±2.03) ° and (3.07±1.75) ° compared with tibial neutral position.@*CONCLUSION@#When a full-length X-ray film is taken on the weight-bearing position of both lower limbs, if there is axial rotation or external rotation of tibia, MPTA will increase or decrease compared with neutral position, which may cause a certain degree of deviation in clinical operation based on the accurate measurement of MPTA. However, the extent to which this bias affects the clinical operation effect remains to be verified. In addition, limited by the total number of samples and the number of measurement groups, whether there is a linear relationship between MPTA deviation and tibial axial rotation needs to be further studied.

RESUMEN

OBJECTIVE@#To investigate CT values of cancellous bone in femoral neck in adults over 60 years with proximal femoral fractures.@*METHODS@#From January 2020 to December 2020, a retrospective analysis was performed on 280 subjects aged 60 years or older who underwent bilateral hip CT examination, including 85 males and 195 females, 120 on the left side and 160 on the right side, aged 75 (66, 82) years old. One hundred thirty-six patients with proximal femoral fractures were included in study group and 144 patients without fractures were included in control group. GEOptima CT was used to scan and reconstruct horizontal, coronal and sagittal layers of proximal femur. CT values of cancellous bone in femoral neck were measured and compared between two groups. The relationship between CT values of cancellous bone of femoral neck and proximal femoral fracture was analyzed statistically.@*RESULTS@#In terms of age, fracture group aged 79(73.3, 85.0) years old, non-fracture group aged 69.5 (64.0, 78.8) years old, and had significant difference in age between two groups (P<0.05). In terms of CT value, regional CT value in fracture group was 8.62(-3.62, 27.15) HU, which was lower than that in non-fracture group 34.31(-5.93, 71.74) HU(P<0.05). CT value on coronal view in fracture group was -8.48(-30.96, 17.46) HU, which was lower than that in non-fracture group 40.49(5.55, 80.71) HU (P<0.05). CT value on sagittal view in fracture group was -31.28(-54.91, -5.11) HU, which was lower than that in non-fracture group 7.74(-20.12, 44.54) HU (P<0.05). CT values on horizontal view in fracture group was 0.17(-23.13, 24.60) HU, which was lower than that in non-fracture group 46.40(10.42, 85.18) HU(P<0.05). The mean regional CT values among three planes in the fracture group were lower than those in the non-fracture group. Logistic regression analysis showed coronal CT value was influencing factors of proximal femoral fracture, and it could be written into regression equations that predict probability of fracture.@*CONCLUSION@#In adults aged over 60 years old, CT values of cancellous bone of femoral neck decreased with increasing age. The smaller CT value of cancellous bone of femoral neck, the greater risk of proximal femoral fracture.

RESUMEN

OBJECTIVE@#To evaluate the short-term efficacy of proximal fibula osteotomy in the treatment of knee osteoarthritis, and to analyze the effect of osteotomy on the tension of the lateral knee soft tissue of patients and verify the reliability of the Arch string theory.@*METHODS@#A total of 71 patients with varus knee osteoarthritis from December 2019 to March 2022 were included, 3 patients dropped out, and 68 patients completed all trials, collected 27 males and 41 females, aged from 51 to 79 years old, with an average of (68.0±7.0 ) years old. The follow-up time ranged from 4 to 12 weeks, with an average of (3.76±1.94) weeks. After admission, the patient underwent Proximal fibula osteotomy, and the tension of lateral knee soft tissue, visual analogue scale (VAS) of pain, the western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and other indicators were recorded before surgery and 1 month after surgery in the weight-bearing state.@*RESULTS@#According to the VAS, the curative effect of a single index was evaluated by referring to the score before and after treatment by Bao Zongzhao. Thirty seven cases were markedly effective, 27 cases were effective, and 4 cases were ineffective. After surgery, 3 patients presented with weakness of dorsalis pedis extension and 1 presented with paresthesia of dorsalis pedis, which disappeared after symptomatic treatment . The VAS and WOMAC score at 1 month after operation were lower than those before operation, and the differences were statistically significant(P<0.001). The tension of lateral knee soft tissue 1 month after operation was lower than that before operation, and the difference had statistical significance(P<0.001).@*CONCLUSION@#Proximal fibula osteotomy is safe and effective in the treatment of varus knee osteoarthritis in the short term. One month after osteotomy, the tension of lateral knee soft tissue increases under weight-bearing state, but the long-term changes still need further observation and follow-up.

RESUMEN

OBJECTIVE@#To evaluate effectiveness of proximal femur bionic nail (PFBN) in treatment of intertrochanteric fractures in the elderly compared to the proximal femoral nail antirotation (PFNA).@*METHODS@#A retrospective analysis was made on 48 geriatric patients with intertrochanteric fractures, who met the selection criteria and were admitted between January 2020 and December 2022. Among them, 24 cases were treated with PFBN fixation after fracture reduction (PFBN group), and 24 cases were treated with PFNA fixation (PFNA group). There was no significant difference in baseline data such as age, gender, cause of injury, side and type of fracture, time from injury to operation, and preoperative mobility score, American Society of Anesthesiologists (ASA) score, Alzheimer's disease degree scoring, self-care ability score, osteoporosis degree (T value), and combined medical diseases between the two groups ( P>0.05). The operation time, intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, occurrence of complications, weight-bearing time after operation, and postoperative visual analogue scale (VAS) score, walking ability score, mobility score, self-care ability score were recorded and compared between the two groups. And the radiographic assessment of fracture reduction quality and postoperative stability, and fracture healing time were recorded.@*RESULTS@#The operations in both groups were successfully completed. All patients were followed up 6-15 months with an average time of 9.8 months in PFBN group and 9.6 months in PFNA group. The operation time was significantly longer in PFBN group than in PFNA group ( P<0.05), but there was no significant difference in intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, change in activity ability score, and change in self-care ability score between the two groups ( P>0.05). The weight-bearing time after operation was significantly shorter in PFBN group than in PFNA group ( P<0.05), and the postoperative VAS score and walking ability score were significantly better in PFBN group than in PFNA group ( P<0.05). Radiographic assessment showed no significant difference in fracture reduction scores and postoperative stability scores between the two groups ( P>0.05). All fractures healed and there was no significant difference in fracture healing time between the two groups ( P>0.05). The incidence of complications was significantly lower in PFBN group (16.7%, 4/24) than in PFNA group (45.8%, 11/24) ( P<0.05).@*CONCLUSION@#Compared with PFNA, PFBN in the treatment of elderly intertrochanteric fractures can effectively relieve postoperative pain, shorten bed time, reduce the risk of complications, and facilitate the recovery of patients' hip joint function and walking ability.

RESUMEN

OBJECTIVE@#To investigate the long-term effectiveness of uncemented allograft-prosthesis composite (APC) for reconstruction of bone defects after proximal femur tumor resection.@*METHODS@#Between June 2007 and March 2014, 21 patients who underwent uncemented APC reconstruction of proximal femur after tumor resection were retrospectively evaluated. There were 9 males and 12 females with an average age of 33.2 years (range, 19-54 years). There were 9 cases of giant cell tumor of bone, 5 cases of osteosarcoma, 4 cases of osteoblastic osteosarcoma, 2 cases of chondrosarcoma, and 1 case of undifferentiated pleomorphic sarcoma. Thirteen cases of benign bone tumors were all classified as stage 3 by Enneking staging; and 8 cases of malignant bone tumors were classified as grade ⅡB in 7 cases and grade ⅡA in 1 case according to the American Joint Committee on Cancer (AJCC) staging system. Among them, 7 patients underwent reoperation after recurrence, and the rest were primary operations; 8 patients presented with pathological fractures. The preoperative Harris hip score (HHS) and American Musculoskeletal Tumor Society (MSTS) score was 40 (30, 49) and 9.1±3.5, respectively. The length of osteotomy was 80-154 mm, with an average of 110 mm. At 1 year after operation and last follow-up, HHS and MSTS scores were utilized to evaluate the function of hip joint; the gluteus medius strength score was used to evaluation of the hip abduction function. Image examinations were taken at 1, 3, 6, 9, and 12 months after operation and every year thereafter to assess the union of allograft-host bone interfaces. Intra- and post-operative complications were also recorded.@*RESULTS@#All patients were followed up 84-163 months (mean, 123.5 months). At 1 year after operation and last follow-up, the HHS and MSTS scores significantly improved when compared with the preoperative scores ( P<0.05). However, there was no significant difference in the HHS score, MSTS score, and gluteus medius strength score between the two time points after operation ( P>0.05). Image examination showed that all allograft-host bone interfaces achieved union after 5-10 months (mean, 7.6 months). At last follow-up, all patients had bone resorption, including 11 severe cases, 4 moderate cases, and 6 mild cases; the bone resorption sites included Gruen 1, 2, and 7 regions. Complications included 10 fractures and 1 prosthetic fracture. Local recurrence occurred in 3 patients and pulmonary metastasis in 3 patients.@*CONCLUSION@#Uncemented APC is a reliable method for the reconstruction of bone defects after proximal femur tumor resection. It has the good long-term effectiveness and possesses obvious advantages in the union at the bone-bone surface.
