Randomized clinical trial of aspirin as prophylaxis for thromboembolism in hip arthroplasty / Ensaio randomizado da aspirina na profilaxia do tromboembolismo em artroplastia do quadril

ABSTRACT Objective: This study aims to evaluate aspirin as a chemical prophylaxis (200 mg) in total hip arthroplasty. Methods: the study compared two groups and used ultrasonography (USG) to screen for low-deep venous thrombosis. Group 1 received 600 mg (control), and Group 2 received 200 mg of (intervention), associated with the use of elastic compression stockings and early walking Results: fourteen patients were allocated to Group A (200mg), and 16 to Group B (600mg); in group A (200mg), 3 cases with thrombus below the popliteal vein were detected at the first USG examination. All of them are in the left lower limb (21.4%). In group B (600 mg), 5 cases were identified after the first exam (31.2%). All cases were asymptomatic and followed the protocol with prophylaxis only with Aspirin. Conclusion: In the statistical data, there were no differences in the presence of thrombus between the 200- and 600 mg groups, which is credited to using low-dose aspirin in low doses (200mg). Hematimetric levels returned to baseline levels and suggested there was no chronic or acute bleeding related to the use of aspirin. The manuscript was prepared according to the CONSORT guideline 2010. Level of Evidence I; Longitudinal Randomized Comparative Clinical Study.

RESUMO Objetivo: Este estudo pretende avaliar a aspirina como profilaxia química (200 mg) na artroplastia total do quadril. Métodos: estudo comparando dois grupos com diferentes doses de aspirina e utilizando a ultrassonografia (USG) para rastreamento da trombose venosa profunda baixa. O grupo 1, 650 mg ao dia de aspirina (controle) e o grupo 2, 200 mg de aspirina ao dia na mesma posologia (intervenção) e associados ao uso de meias elásticas de compressão e deambulação precoce. Resultados: quatorze pacientes foram alocados no grupo A (200 mg) e 16 no grupo B (650 mg). No grupo A foram detectados 3 casos com trombos abaixo da veia poplítea ao USG sendo 21,4%. Já no grupo B, 5 casos foram identificados após o primeiro exame (31,2%). Todos assintomáticos e sem sinais de sangramento ativo ou queda da hematimetria no momento da detecção dos trombos. Conclusão: os dados sugerem não haver diferença na incidência de trombo em ambos os grupos, não sendo a profilaxia com a aspirina dose-dependente. Os níveis hematimétricos retornaram aos níveis iniciais o que sugere não ter havido sangramento crônico ou agudo relacionado ao uso. Nível de Evidência I; Estudo Clínico Randomizado Longitudinal Comparativo.

Comparison of effect between internal fixation and total hip replacement in the treatment of displaced femoral neck fracture in middle age patients / 中国骨伤

OBJECTIVE@#To analyze and compare the clinical efficacy of internal fixation and total hip replacement in the treatment of displaced femoral neck fracture from 55 to 65 years.@*METHODS@#From September 2016 to August 2020, 86 patients with Garden type Ⅲ or Ⅳ femoral neck fracture were divided into two groups according to different surgical methods. Among them, 38 patients were treated with lag screws for internal fixation, there were 26 males and 12 females, aged 55 to 64 years old with an average of(60.2±3.1) years;the other 48 patients were treated with total hip replacement, including 28 males and 20 females, aged from 57 to 65 years old with an average of(61.3±3.8) years. The time from injury to operation ranged from 1 to 3 days. The reoperation rate, incidence of deep infection, Harris score of hip joint function, visual analogue scale(VAS) of pain and patients reported outcome scores(European five-dimensional Health Questionnaire, EQ-5D) were compared between two groups.@*RESULTS@#All patients were followed up for 24 to 54 months with an average of (35.8±10.3) months. There was significant difference in reoperation rate between two groups (P<0.05). There was no significant difference on the incidence of deep infection, hip Harris score and VAS between two groups(P>0.05) . The postoperative EQ-5D score of patients with internal fixation was lower than that of total hip replacement, and the difference was statistically significant(P<0.05).@*CONCLUSION@#Both the surgery of internal fixation and total hip replacement have similar effect in short-and medium term among the patients aged 55 to 65 years old. However, for the reoperation rate, the group of internal fixation was higher than that of total hip replacement. For the subjective functional score of patients, the group of internal fixation was lower than that of total hip replacement.

The cost of total hip replacement: a multicentric TDABC comparison in Brazil / O custo da artroplastia de quadril: uma comparação multicêntrica TDABC no Brasil

Objective: Monitoring costs is critical in searching for a more effective healthcare system. This study aimed to comprehend the care pathway and measure the costs associated with hip replacement surgeries in different hospitals in Brazil. Methods: The time-driven activity-based costing method was applied for cost data collection and analyses. Data on 62 patients were retrieved from five public hospitals. A descriptive cost analysis was followed by a comprehensive analysis of the variability in each hospital's care process, leading to suggestions for cost-saving opportunities along with the surgical care pathway. As a final analysis, the cost of surgical treatment was contrasted with the national reimbursement fee. Results: The mean cost per patient of the total sample was $5,784 (MIN-MAX $2,525.9-$9,557.8). Pre- and post-surgery hospitalization periods demonstrated the highest variability in length of time and resource consumption among centers. Compared to the national best practice fee, the average cost per inpatient total hip arthroplasty (THA) pathway from all six hospitals was approximately 7x the national reimbursement. Conclusion: The application of the TDABC allowed us to identify differences in the surgical care pathway among hospitals, which could be explored in further studies aimed at designing a benchmark surgical pathway. Differences in how the treatment is delivered to patients also justified the high-cost variability among centers.

Objetivo: O custo do monitoramento é um elemento-chave na busca contínua por um sistema de saúde mais eficaz. O objetivo deste estudo foi compreender a trajetória assistencial e mensurar os custos associados às cirurgias de artroplastia do quadril em diferentes hospitais do Brasil. Métodos: O método de custeio baseado em atividades orientado pelo tempo foi aplicado para a coleta e análise de dados de custos. Os dados de 62 pacientes foram recuperados de cinco hospitais públicos. Uma análise descritiva de custos foi seguida por uma análise abrangente da variabilidade no processo de atendimento de cada hospital, levando a sugestões de oportunidades de redução de custos junto com a via de atendimento cirúrgico. Como análise final, o custo do tratamento cirúrgico foi contrastado com o valor de reembolso nacional. Resultados: O custo médio por paciente da amostra total foi de $ 5.784 (MIN-MAX $ 2.525,9-$ 9.557,8). Os períodos de internação pré e pós-operatórios demonstraram a maior variabilidade no tempo e no consumo de recursos entre os centros. Em comparação com o reembolso nacional de melhores práticas, o custo médio por cirurgia de prótese de quadril de paciente internado de todos os seis hospitais foi de aproximadamente 7x o reembolso nacional. Conclusão: A aplicação do TDABC nos permitiu identificar diferenças na via de atendimento cirúrgico entre hospitais, o que poderia ser explorado em estudos futuros que visem projetar uma via cirúrgica de referência. As diferenças na forma como o tratamento está sendo entregue aos pacientes também contribuíram para justificar a alta variabilidade dos custos entre os centros.

Old unreduced and untreated fracture of the acetabulum is seen more commonly in developing countries and can be due to various reasons. Various methods can be used in the management of such cases which in general includes arthrodesis in young and total hip replacement in elderly patients. Acetabular fractures associated with acetabular defect pose challenge to the treating surgeon and the management of such defects plays an important role in the ?nal outcome of the surgery. We are here reporting a case of a 36 years old male patient who presented with 1 year 6 months old fracture of posterior wall of the acetabulum who is treated with THR with acetabular reconstruction using bone graft and acetabular augment. The patient was under regular follow up and now after 6 months of surgery patient is having good functional improvements with painless range of motions at index hip

Factores de riesgo de luxación en una serie de 2732 prótesis totales de cadera / Risk Factors for Dislocation in a Series of 2732 Total Hip Replacements

Introducción: La luxación de la prótesis total de cadera puede afectar los resultados del implante, la calidad de vida del paciente, y el costo del proceso. Su etiología es multifactorial. Objetivos: Identificar posibles factores de riesgo relacionados con la aparición de luxación en prótesis total de cadera en una serie de casos. Métodos: En una serie de 2732 prótesis total de cadera, en la que hubo 92 luxaciones (3,4 por ciento), se compararon factores relacionados con el paciente, el implante, y la técnica quirúrgica uilizada en el Hospital La Paz-IDIPaz de Madrid entre los años 2000 y 2016. Se utilizó el análisis de regresión para la significación de dichos factores. Resultados: De las 92 luxaciones, 62 fueron tratadas de manera conservadora (67,4 por ciento) y 30 pacientes precisaron de cirugía de revisión (32,6 por ciento). El estudio multivariado mostró significación estadística en los siguientes factores de riesgo: estado de la columna lumbar (p < 0,001), y una pobre reconstrucción del centro de rotación de la cadera (p= 0,035), y cúpulas posicionadas fuera de las ventanas de Lewinnek (p < 0,001) y del mecanismo abductor (p < 0,001) en relación con la técnica quirúrgica. No hubo factores significativos en relación con el tipo de implante, diámetro de la cabeza femoral o par de fricción. Conclusiones: La patología lumbar aumenta el riesgo de luxación en la prótesis total de cadera. Una adecuada reconstrucción de la cadera, que incluya la posición de la cúpula y el centro de rotación de la cadera, así como del mecanismo abductor ayudaría a mejorar la tasa de inestabilidad(AU)

Introduction: The dislocation of the total hip replacement can affect the results of the implant, the quality of life of the patient, and the cost of the process. Its etiology is multifactorial. Objectives: To identify possible risk factors related to the appearance of dislocation in total hip replacement in a series of cases. Methods: In a series of 2732 total hip prostheses, in which there were 92 dislocations (3.4percent), factors related to the patient, the implant, and the surgical technique used at La Paz-IDIPaz Hospital in Madrid were compared, from 2000 to 2016. Regression analysis was used for the significance of these factors. Results: Out of 92 dislocations, 62 were treated conservatively (67.4 percent) and 30 patients required revision surgery (32.6 pecent). The multivariate study showed statistical significance in the following risk factors: state of the lumbar spine (p <0.001), and poor reconstruction of the center of rotation of the hip (p = 0.035), and domes positioned outside Lewinnek windows (p <0.001) and the abductor mechanism (p <0.001) in relation to the surgical technique. There were no significant factors in relation to the type of implant, diameter of the femoral head or friction torque. Conclusions: Lumbar pathology increases the risk of dislocation in total hip replacement. Proper hip reconstruction, including the position of the dome and the center of rotation of the hip, as well as the abductor mechanism, would help to improve the rate of instability(AU)

Functional outcome after total hip replacement following 30 years neglected posterior hip dislocation: a rare case report

Neglected traumatic dislocations of the hip is one of disabling condition in lower extremity which are seldom found in adults. However, in developing countries, neglected-unreduced traumatic dislocations are not uncommon. Total hip replacement (THR) still remains a recommendation for the treatment of neglected hip dislocation which occurs more than 3 months. A 45- years-old female came to the outpatient clinic complaining pain on her right hip with history of trauma 30 years before, but instead of seeking medical treatment, she went to bonesetter instead. On physical examination, there is 5 cm leg length discrepancy, and the patient walked with limping gait. Conventional x-ray confirmed persistent dislocation of the right hip. A soft tissue release procedure and femoral neck osteotomy with skeletal traction was done before, followed by delayed THR two months after. The patient’s functional status was improved, and the HHS score increased from 48 to 87. The patient had no pain or significant complaints, except for a finding of mild residual Trendelenburg gait.

Assessment of Functional Outcome between Cemented and Uncemented Total Hip Replacement: A Comparative Study

Introduction: Total hip arthroplasty (THA) or total hipreplacement is the most effective, economical surgicalprocedure for femoral neck fractures or hip joint diseasesamong elderly patients. The main purpose is to reduce painas well as reduce joint function. Hence, the aim of the presentstudy was to assess the functional outcome between cementedand uncemented total hip arthroplasty.Material and Methods: The present study was anobservational study which was hospital‑based conductedamong 140 cases divided into two groups with 70 cases ineach group. All the patients of 50–80 years in which THR wasindicated were taken in this study. Patients with neurovasculardeficit and active infection were excluded from this study.In Group 1, cemented THR was done while in Group 2uncemented THR was done. Pain was evaluated using Harriship score.Results: In cemented group, majority of the cases wereavascular necrosis 24(34%) followed by fracture neck offemur 10 (14%), fracture-dislocation of hip 6 (8%) and inuncemented group, maximum cases were avascular necrosis36 (51%) followed by fracture neck of femur 21 (30%) andfracture-dislocation of hip 14 (20%). mean difference amongcemented group was 82.41±7.2 at 6 weeks followed by81.31±7.5 in uncemented group and this difference was foundto be statistically significant at p value 0.001.Conclusion: Cemented implants showed better functionaloutcomes than uncemented in total hip arthroplasty at 6weeks, 3 months and at 6 months.

Systematic evaluation and meta-analysis of total hip arthroplasty with three-dimensional printing model in preoperative planning / 中国组织工程研究

BACKGROUND: Three-dimensional (3D) printing-assisted total hip arthroplasty plays an important role in preoperative planning, intraoperative guidance and positioning, and production of individualized implants. It has important clinical significance for the treatment of hip joint diseases. OBJECTIVE: To evaluate the clinical efficacy of preoperative planning using 3D printed models to assist total hip arthroplasty by systematic evaluation and meta-analysis. METHODS: PubMed, Embase, Cochrane Libray, CNKI, Wanfang databases were retrieved electronically for the articles published before December 2019. The keywords were “hip arthroplasty, hip replacement, THA, 3D printing, three dimensional printing” in Chinese and English, respectively. The clinical controlled trials of 3D printed models versus non-3D printed models to assist total hip arthroplasty in the treatment of hip joint diseases were enrolled. The literature was screened according to the inclusion and exclusion criteria; data were extracted; and the quality of the included studies was evaluated using the Cochrane 5.1.0 bias risk assessment tool, followed by data analysis using RevMan 5.3 software. RESULTS AND CONCLUSION: (1) Fourteen controlled studies were included, involving 601 participants, including 279 cases in the 3D group and 322 cases in the traditional surgery group. (2) Meta-analysis results showed that during the first hip arthroplasty, the operation time in the 3D group was shorter than that in the traditional surgery group [SMD=-0.89, 95%CI (-1.15, -0.64), P 0.05]. During revision surgery, the operation time in the 3D group was shorter than that in the traditional surgery group [SMD=-1.39, 95% CI (-1.92, -0.86), P < 0.05], and Harris score was higher than that in the traditional surgery group [SMD=1.51, 95%CI (-0.05, 2.96), P < 0.05]. The intraoperative blood loss and postoperative drainage volume in the 3D group were less than those in the traditional surgery group [SMD=-1.90, 95%CI (-2.82, -0.99), P < 0.05; SMD=-2.87, 95%CI (-3.36, -2.37), P < 0.05]. The anteversion angle and abduction angle in the 3D group were closer to the preoperative design angle compared with the traditional surgery group [SMD=-1.24, 95%CI (-1.57, -0.91), P < 0.05; SMD=-1.71, 95%CI (-2.96, -0.45), P < 0.05]. (3) These results show that compared with traditional total hip arthroplasty, 3D printing assisted total hip arthroplasty can significantly shorten the operation time, reduce the amount of intraoperative blood loss and postoperative drainage, improve the accuracy of total hip arthroplasty, and can better relieve pain, and improve the quality of life. However, due to the low quality of the included literature, high-quality large-sample, multi-center randomized controlled trials are still needed to confirm the clinical efficacy.

Evaluación costo-efectividad de las prótesis con superficie cerámica-polietileno vs. metal-polietileno para reemplazo articular primario de cadera en Colombia / Cost-Effectiveness of Ceramic-Polyethylene Vs Metal-Polyethylene Bearing for Primary Total Hip Replacement in Colombia

Introducción Existe una diferencia estadísticamente significativa del 1.2% en la tasa de revisión a 15 años a favor de cerámica- polietileno altamente entrecruzado (CP), demostrada en el registro nacional de artroplastia australiano. Nuestro objetivo es evaluar la costo-efectividad entre los pares: cerámica-polietileno altamente entrecruzado (CP) y metal- polietileno altamente entrecruzado (MP) para el pagador en Colombia. Materiales y métodos Se construyó un árbol de decisiones TreeAge Pro® comparando CP vs MP desde la perspectiva del Sistema de Salud Colombiano (SSC). Los parámetros se tomaron de la mejor evidencia disponible, para la efectividad se realizó una revisión sistemática de la literatura y para los costos se usaron tarifas del mercado local. Se determinó la relación de costo-efectividad incremental, asumiendo un horizonte temporal de 15 años y aplicando una tasa de descuento del 5% para costos y efectividad. La incertidumbre fue controlada por un análisis de sensibilidad determinístico y probabilístico. Resultados Para el SSC, con un umbral de 1 PIB per cápita por año de vida ganado ajustado por calidad (AVAC), en adultos llevados a RTC el uso de CP no es costo-efectiva, dado que la efectividad es similar (MP:11,32 AVAC vs CP: 11,36 AVAC) y el costo es tres veces mayor (MP $ 861.826 COP vs CP $ 2.298.090 COP). El análisis de sensibilidad determinístico demuestra que la variable más importante en el resultado es el costo de la cerámica. Discusión Para el SSC el uso rutinario de cabezas de cerámica en RTC no es una estrategia costo-efectiva.

Background There is a statistically significant difference of 1.2% in the revision rate in a 15 year follow in favour of the use of ceramic on highly cross-linked polyethylene (CP) recently described in the Australian National Joint Registry. The purpose of this study is to compare the cost-effectiveness of CP implants and metal-on-highly cross-linked polyethylene (MP) implants in patients undergoing total hip replacement (THR). Materials and methods A TreeAge Pro® decision tree was constructed in order to determine cost-effectiveness between two bearing surfaces: CP or MP from the perspective of the Colombian Health Care System (CHCS). The model parameters where taken from the best available evidence. For the effectiveness, a systematic review of the literature was performed, and costs were taken from local market rates. The incremental cost-effectiveness ratio was determined assuming a time horizon of 15 years, and a discount rate of 5% was used for costs and effectiveness. Cost-effectiveness uncertainty was controlled with deterministic and probabilistic sensitivity analysis. Results For the CHCS, with a 1PIB per capita threshold adjusted per QALY in adults undergoing (THR), the use of a CP implant is not cost-effective, given that the effectiveness is similar (11.32 QALY for MP vs 11.36 QALY for CP), and the cost is three times higher (MP $ 861.826 COP vs CP $ 2.298.090 COP). The deterministic sensitivity analysis showed that the most important variable in the results is the ceramic cost. Discussion for the CHCS the routine use of ceramic-highly cross-linked polyethylene bearing surface in a THR is not a cost-effective strategy.

Analysis Of Femoral Neck Anteversion In Dry Adult Bones: A Morphometric Study

Introduction: The femoral neck anteversion can be defined as the angle between femoral bicondylar plane and aplane passing through the centre of the neck and head of femur. Adult femoral anteversion has been documentedat the range between 7-16 degrees.This angle is widely recognized as an important factor for hip stability. Thepresent study aimed to evaluate the normal anteversion range in adult Indian femur which would be of great helpin explorative orthopedic procedures and in designing of hip prosthesis.Materials and Methods: Study conducted in 202 femurs of 94 male (48 right and 46 left) and 108female bones (52right and 56 left). And the angle was measured using Kingsley Olmsted Method.Observation and Results: The mean value of anteversion angle of femurwas 7.61 degrees for male and 12.71degrees for females.Mean anteversion angle for both male and female femur was 10.37 degrees. Retroversionwas observed in 10 femurs(5%) and neutral version was observed in12 femurs (5.9%).Conclusion:Determining the anteversion angle is crucial for the diagnostic and therapeutic planning of patientswith various pathologies such as hip development dysplasias, cerebral palsy, varum thigh, flat thigh,epiphysiolysis, congenital club foot, congenital dislocation of the hipand other development abnormalities.Statistical analysis revealed sexual dimorphism in anteversion in Indians being greater among females thanmales

Single Stage Cementless Bilateral Total Hip Replacement Surgery: Case Report And Review Of Literature

Two staged bilateral total hip replacement (THR) is commonly performed for bilateral hip end stage arthritis and is preferred as THR is a complex planned surgery and performing both sides simultaneously may be fraught with risks and complications. However, many studies now indicate that in carefully selected patients , single stage or simultaneous bilateral THR can be performed with successful and cost effective results. We report a case of one-stage bilateral THR performed in a 22 year old with bilateral severe arthritis due to ankylosing spondylitis. Patient was severely disabled due to pain and was only ambulating on wheelchair. After a successful single stage bilateral THR, patient recovered fully and after 6 weeks was walking independently without any pain, with full function of both hips and performing his occupation normally. The surgical costs to the patient and hospital were both economical. We conclude that single stage bilateral THR is a better surgical option for young and fit patients with bilateral hip arthritis.

Short-and long-term results of SuperPath minimally invasive arthroplasty in the treatment of femoral head necrosis / 临床外科杂志

Objective To study the short-and long-term effects of SuperPath minimally invasive arthroplasty for the treatment of femoral head necrosis.Methods The subjects were 50 patients with femoral head necrosis.Randomly divided into the control group and observation group with 25 cases in each group.The patients in the control group were treated with total hip replacement through anterolateral small incision.The patients in the observation group were treated with minimally invasive total hip replacement through SuperPath incision.Compared two groups of the perioperative indexes and the incidence of complications, and all patients were followed up for 6 months, compared before and after operation of the Harris hip function score and visual analogue method were evaluated.Results The observation group of the drainage flow[ (211.83±23.76) ml], intraoperative blood loss[ (354.06±38.28) ml], hospitalization time[ (8.74±1.53) d], the difference of leg length[ (12.97±3.05) mm] and thigh circumference[ (5.41±0.58) mm] was significantly lower than the control group[ (150.49±18.61) ml, (213.95±30.24) ml, (4.52±1.06) d, (8.12±2.30) mm and (2.87±0.51) mm, respectively] (P＜0.05).1 year after operation, the Harris score (89.30±4.19) and Barthel index (90.63±4.95) in the observation group were significantly higher than the control group (81.86±5.24, 79.47±5.36) (P＜0.05).VAS score was significantly lower in observation group (0.85±0.43) than that in control group (2.09±0.61) (P＜0.05).The incidence of complications in the two groups was not significantly different (P＞0.05).Conclusion SuperPath incision minimally invasive total hip arthroplasty for the treatment of avascular necrosis of the femoral head has advantages such as small trauma, low complication and significant effect.It can relieve pain and promote hip joint function and quality of life recovery.

Prognostic Factors and Clinical Outcomes after Treatment of Periprosthetic Femoral Fractures Using a Cable-plate / 대한고관절학회지

PURPOSE: To analyze prognostic factors for the treatment of periprosthetic femoral fractures (PFFs) using the cable-plate construct. MATERIALS AND METHODS: A retrospective review of a consecutive series of 41 PFFs treated by osteosynthesis using the cable-plate system. The mean age of patients was 67.3±12.1 years (range, 42-86 years) and the mean follow-up period was 31.5±11.6 months (range, 12–58 months). Fresh frozen cortical strut allografts were leveraged in three cases for additional stability. Prognostic factors that may potentially affect clinical outcomes were analyzed. RESULTS: At the time of final follow-up, fracture union was obtained in 29 hips (70.7%; Group I) after an average of 13.5 weeks (range, 12–24 weeks). Healing failure after surgical treatment was observed in 12 cases (29.3%; Group II), including delayed union (n=10) cases and nonunion (n=2). Factors significantly associated with fracture union included fracture pattern (P=0.040), plate overlap percentage to stem length (P<0.001) and T-score at the preoperative bone mineral density (P=0.011). Transverse-type fractures around or just distal to a well-fixed femoral stem were observed in six cases (50.0%) of Group II. CONCLUSION: The cable-plate osteosynthesis of PFFs should be performed with caution in transverse-type fractures or in cases with severe osteoporosis. Fixation with sufficient plate overlap to stem length may be critical to prevent healing failure.

Discusión En el 100% de los casos se encontró osteointegración del implante y los resultados son comparables con los reportes de la literatura. Consideramos que el uso de vástagos cortos en el Reemplazo total de Cadera es un procedimiento seguro, con buenos resultados, teniendo la ventaja de una adecuada integración ósea del implante y garantizar un mejor stock óseo en una próxima cirugía.

Background The growing trend in the use of non-cemented implants and the development of technologies that attempt to restore the anatomy and joint function with greater bone preservation has increased the use of short stems in the total hip replacement (THR). The objective of this study is to describe functional results, radiological restoration of the anatomy, complication and revision rate of patients undergoing THR using short femoral stems with metaphyseal cervical fixation with lateral cortical support. Materials and Methods A prospective descriptive study was performed that included 45 hips of patients with hip osteoarthritis of any origin. The follow-up was 18 months. The outcome variables evaluated were: 1. Integration of the implant, 2. Complications dependent on the femoral implant, 3. Subsidence, and 4. Re-intervention. The functional result was additionally evaluated using the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Results During the period from December 2011 to July 2017, an improvement was observed in functional status in 97% (n: 44) of patients, with no reoperations. Discussion Bone integration of the implant was observed in 100% of the cases, making the results comparable with the reports in the literature. It is believed that the use of short stems in total hip replacement is a safe procedure, with good outcomes. It also has the advantage of an adequate bone integration of the implant, and guaranteeing a better bone stock in the next surgery.

Replacement Arthroplasty For The Treatment Of Intra-Capsular Fracture Neck Femur In The Elderly

Fracture neck of femur is commonly seen in elderly patients with trivial injury due to osteoporotic bones. If union of fracture is not likely to be achieved, the surgeon has to choose the alternate method suitable to the patients depending on their age, life style, profession and economical status. From September 2014 to October 2016, total 25 cases of intra-capsular fracture neck femur (IC#NF) were treated by total hip arthroplasty (THR)- 3 cases, bipolar hemi arthroplasty - 12 cases, Austin-moore's hemi arthroplasty (AMP)- 7 cases and Girdle-stone excision arthroplasty - 3 cases. Detailed personal, family history and patients personal requirements were considered to decide the suitable procedures for these patients. Harris hip score was followed to all the patients at final follow up which is ranging from 45 to 83 with mean 64.All the patients were ambulatory independently and performing their daily routine activities. There were no major complications.

Spinopelvic Alignment and Low Back Pain after Total Hip Replacement Arthroplasty in Patients with Severe Hip Osteoarthritis

STUDY DESIGN: Retrospective observational study. PURPOSE: We examined change in lumbrosacral spine alignment and low back pain (LBP) following total hip arthroplasty (THA) in patients with severe hip osteoarthritis (OA). OVERVIEW OF LITERATURE: Severe hip osteoarthritis has been reported to cause spine alignment abnormalities and low back pain, and it has been reported that low back pain is improved following THA. METHODS: Our target population included 30 patients (29 female, mean age 63.5 years) with hip OA who underwent direct anterior approach THA. There were 12 cases with bilateral hip disease and 18 cases with unilateral osteoarthritis. Visual analogue scale (VAS) scores for LBP and coxalgia, the Roland-Morris Disability Questionnaire (RDQ), and the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) were assessed before and after surgery. Spinal alignment metrics were measured before and after surgery. RESULTS: VAS for LBP change from preoperative to final postoperative observation was significantly improved (p < 0.05), as was VAS for hip pain (p < 0.001). RDQ improved significantly (p < 0.01). All five domains of JOABPEQ were significantly improved (p < 0.05). In terms of coronal alignment, lumbar scoliosis change from preoperative to last observation was significantly reduced (p < 0.05). There were no significant changes in the sagittal alignment metrics. In addition, there was a correlation between before and after RDQ difference and before and after lumbar scoliosis difference (p < 0.05). VAS for LBP (p < 0.05) as well as RDQ (p < 0.05) were significantly improved only in unilateral OA. Lumbar scoliosis was significantly improved in cases of unilateral OA (p < 0.05), but alignment did not improve in cases of bilateral OA (p=0.29). CONCLUSIONS: The present study demonstrates improvements in VAS for LBP, RDQ, and all domains of JOABPEQ. There were also significant reductions in lumbar scoliosis and an observed correlation of RDQ improvement with lumbar scoliosis improvement. We were able to observe improvements in lumbar scoliosis and low back pain only in cases of unilateral OA. It has been suggested that the mechanism of low back pain improvement following THA is related to compensatory lumbar scoliosis improvement.

A Case of Stewart-Treves Syndrome on Lower Extremity Related to Hysterectomy and Total Hip Replacement Surgery / 대한피부과학회지

Stewart-Treves syndrome (STS) is a rare cutaneous angiosarcoma that develops in chronic lymphedema. The majority of STS is described in the upper extremity after aggressive locoregional therapy for breast cancer and is rarely reported in lower extremities. A 68-year-old woman presented with a 3-month history of multiple purpuric tumorous plaques and nodules on the right posterior thigh. She had a history of radical hysterectomy with lymph node dissection and postoperative radiotherapy due to uterine cervical cancer 16 years ago. She received right total hip replacement surgery due to hip joint avascular necrosis 14 years ago. She had suffered from chronic leg edema, especially on the right side. Skin biopsy on the right posterior thigh showed irregular vascular channels lined by atypical endothelial cells. Special stains showed positivity for CD31, CD34, factor VIII, and D2~40, which are pan-vascular or lymphatic markers. She showed a pelvic mass and pelvic bone metastasis on radiologic staging work-up. She refused all treatment, including surgery, radiotherapy, and chemotherapy, except for pain control. She died 2 months after diagnosis of this highly malignant tumor. The lymphedema on both lower extremities after uterine cervical cancer treatment was aggravated especially on the right lower extremity after right total hip replacement surgery. Increased weight of the right lower extremity resulted in 4 episodes of recurrent hip dislocation. We contend that these multiple factors (uterine cervical cancer treatment, total hip replacement surgery on the right side, and recurrent hip dislocations) attributed to development of Stewart-Treves syndrome. We herein report a case of Stewart-Treves syndrome of the lower extremity following chronic leg lymphedema after uterine cervical cancer treatment and hip surgery.
