Phenol versus lidocaine in obturator nerve neurolysis for hip joint pain / Fenol contra lidocaina em neurólise do nervo obturador para dor articular do quadril

ABSTRACT Introduction: For patients with severe hip osteoarthritis without clinical or socioeconomic conditions for total hip replacement, the obturator nerve block may serve for pain control and functional improvement. Either lidocaine or phenol are used, although the latter is expected to last longer. Objectives: Compare hip pain and functional performance after obturator nerve block with phenol versus lidocaine in patients with severe hip osteoarthritis who failed conservative treatment. Methodology: Forty-four patients scheduled for total arthroplasty due to severe osteoarthritis were randomized to the anterior branch of the obturator nerve with phenol (PG) or 1% lidocaine (LG), guided by electrical stimulation. Patients were evaluated with VAS, WOMAC, and pressure pain dolorimetry before the procedure and in the first and fourth months afterward. Results: Both groups improved significantly in pain control, pressure dolorimetry and functioning in the first month with reduced effect after 4 months, although the scores were still better than baseline. No statistical difference could be noticed between the groups. Severe adverse effects were not reported. Conclusion: Both lidocaine and phenol are equally effective and safe in the obturator nerve block for the control of pain and improvement in functioning in patients with severe hip OA. Evidence Level I; Randomized control trial, double-blind .

RESUMO Introdução: Em pacientes com osteoartrite grave do quadril, sem condições clínicas ou socioeconômicas para a substituição total do quadril, o bloqueio do nervo obturador pode servir para o controle da dor e ganho funcional. Pode-se usar lidocaína ou fenol, embora seja esperado que o último apresente maior duração. Objetivo: Comparar a dor no quadril e o desempenho funcional após o bloqueio do nervo obturador com fenol versus lidocaína em pacientes com osteoartrite grave do quadril que não obtiveram sucesso no tratamento conservador. Metodologia: Quarenta e quatro pacientes programados para artroplastia total devido à osteoartrite grave foram randomizados para o ramo anterior do nervo obturador com fenol (PG) ou lidocaína a 1% (LG), guiados por estimulação elétrica. Os pacientes foram avaliados com EVA, WOMAC e dolorimetria de dor por pressão antes do procedimento e no primeiro e quarto meses seguintes. Resultados: Ambos os grupos apresentaram melhora significativa no controle da dor, na dolorimetria por pressão e na funcionalidade no primeiro mês, com efeito reduzido após quatro meses, embora as pontuações ainda fossem melhores do que a linha de base. Não foi possível observar nenhuma diferença estatística entre os grupos. Não foram relatados efeitos adversos graves. Conclusão: Tanto a lidocaína quanto o fenol são igualmente eficazes e seguros no bloqueio do nervo obturador para o controle da dor e melhora da funcionalidade em pacientes com OA grave de quadril.

Effects of SuperPATH approach versus posterolateral approach in total hip replacement on inflammatory response, hip function, and quality of life in patients with hip diseases / 中国基层医药

Objective:To investigate the effects of SuperPATH approach versus conventional posterolateral approach in total hip replacement on inflammatory response, hip function, and quality of life in patients with hip diseases. Methods:The clinical data of 140 patients with hip diseases who underwent total hip replacement in Shanxian Central Hospital from March 2017 to May 2019 were retrospectively analyzed. These patients were divided into SuperPATH approach ( n = 70) and posterolateral approach ( n = 70) groups. Operation-related indexes, inflammatory response indexes, hip function, quality of life, and pain were compared between the two groups. Results:Intraoperative blood loss was significantly less in the SuperPATH approach group than in the posterolateral approach group [(105.40 ± 15.11) mL vs. (196.89 ± 24.26) mL, t = 26.74, P < 0.001]. Incision length, postoperative time to getting out of bed, length of hospital stay in the SuperPATH approach group were (6.85 ± 1.42) cm, (2.92 ± 0.28) days, and (6.67 ± 1.36) days, respectively, which were significantly shorter than those in the posterolateral approach group [(13.07 ± 1.89) cm, (8.36 ± 1.45) days, (10.91 ± 1.34) days, t = 19.36, 30.82, 18.58, P < 0.001]. Operative time was significantly longer in the SuperPATH approach group than in the posterolateral approach group [(69.38 ± 8.62) minutes vs. (60.45 ± 7.79) minutes, t = 6.43, P < 0.001). The scores of social role functioning, general health perceptions, vitality, mental health, bodily pain, emotional role functioning, physical functioning, and physical functioning measured 6 months after surgery were significantly higher in the SuperPATH approach group than in the posterolateral approach group ( t = 9.12, 11.80, 11.64, 11.69, 6.45, 11.79, 6.04, 10.74, all P < 0.001). There were no significant differences in C-reactive protein and erythrocyte sedimentation rate measured 3 and 14 days after surgery between the two groups (both P > 0.05). Harris score used for evaluation of hip function 1 month after surgery was significantly higher in the SuperPATH approach group than in the posterolateral approach group [(76.42 ± 4.17) points vs. (69.37 ± 5.11) points, t = 8.94, P < 0.001]. The Visual Analog Scale score 3 days after surgery was significantly lower in the SuperPATH approach group than in the posterolateral approach group [(3.18 ± 0.21) points vs. (4.26 ± 0.29) points, t = 25.23, P < 0.001]. Conclusion:Compared with the conventional posterolateral approach, the SuperPATH approach for total hip arthroplasty takes longer operative time, but it can better reduce early postoperative pain, promote hip function recovery, and improve quality of life.

A comparative study on the clinical effects of hip arthroplasty through direct anterior approach in lateral decubitus in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia / 中华地方病学杂志

Objective:To compare the clinical effects of hip arthroplasty through direct anterior approach (DAA) in lateral decubitus in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia.Methods:The prospective study method was used to select the patients who needed hip arthroplasty in the Fourth Department of Orthopedics, the Second Affiliated Hospital of Harbin Medical University from January 2015 to December 2019. All of them were operated with lateral decubitus DAA. According to the inclusion criteria, they were divided into Kacshin-Beck disease hip osteoarthritis group (group A) and congenital acetabular dysplasia hip osteoarthritis group (group B). Hip Harris score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, visual analogue scale (VAS) score were conducted, and hip abduction angle and flexion angle were measured before surgery, 3, 14 days and 1, 3, and 12 months after surgery.Results:Nineteen and twenty-two patients were included in group A and group B, respectively. All patients successfully completed the surgery. There was no significant difference in Harris score between the two groups before surgery, 3, 14 days, and 1, 12 months after surgery ( P > 0.05). There were no significant differences in WOMAC score, VAS score, hip abduction angle and hip flexion angle between the two groups before surgery and each time point after surgery ( P > 0.05). In the same group, there were significant differences in Harris score, WOMAC score, VAS score, hip abduction angle and hip flexion angle at different time points ( P < 0.001). All postoperative indicators were significantly improved compared with those before surgery. Conclusions:There is no significant difference in the clinical effects of hip arthroplasty through lateral decubitus DAA in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia. This surgical method has good therapeutic effect on both types of hip osteoarthritis.

Two-stage total hip arthroplasty for chronic septic hip arthritis / 中华创伤骨科杂志

Objective:To analyze the clinical efficacy of two-stage total hip arthroplasty in the treatment of chronic septic hip arthritis.Methods:From January 2008 to March 2020, 17 patients with chronic septic hip arthritis (17 hips) received two-stage total hip arthroplasty at Department of Orthopaedic Surgery, The First Affiliated Hospital to of Fujian Medical University. They were 11 males and 6 females, with an average age of 54.5 years (from 19 to 77 years) and 9 left and 8 right hips affected. There were 10 cases of primary septic hip and 7 cases of secondary infection after hip surgery. Three patients had undergone debridement in other hospitals and one patient had developed a sinus tract. In the first stage operation, the diseased femoral head and neck were resected to implant an articulating spacer after thorough debridement; in the second stage operation, the spacer was removed to implant a uncemented artificial hip prosthesis in 16 cases or a cemented artificial hip prosthesis in one case. Recorded were the results of microbial culture, operation time, intraoperative blood loss, and therapeutic outcomes of the patients.Results:Pathogenic data were available in 13 patients and the culture was negative in 4. The pathogens were detected by metagenomic next-generation sequencing in 2 patients with culture negative. In the first stage operation, operation time averaged 140.6 min (from 90 to 176 min) and intraoperative blood loss 361.8 mL(from 100 to 1 000 mL); in the second stage operation, operation time averaged 130.3 min (from 91 to 166 min)and blood loss 291.2 mL(from 50 to 700 mL). The average interval between the first and the second stage operations was 115.0 days(from 66 to 227 d). During the interval, spacer fracture occurred in one case, spacer dislocation in one case and lower extremity deep venous thrombosis in one case. All the patients were followed up for 12 to 82 months (average, 36.7 months) after second stage operation. The inflammatory indexes decreased to normal in all the 17 patients and infection recurrence was observed in none of them.Conclusions:Two-stage total hip arthroplasty may result in a high rate of successful treatment of chronic septic hip arthritis. Specific use of sensitive antibiotics after identification of specific pathogenic microorganisms by multiple methods is the key to a successful treatment.

The effects of periacetabular osteotomy in the treatment of borderline developmental dysplasia of the hip / 中华骨科杂志

Objective:To investigate the effects of periacetabular osteotomy (PAO) in treating borderline developmental dysplasia of the hip (DDH).Methods:The patients with borderline DDH [lateral center-edge angle (LCEA): 18°-25°) who received PAO with follow-up duration for more than 2 years from January 2011 to January 2018 in our hospital were retrospectively analyzed. The patients in the control group were matched on a 1∶2 ratio based on gender, age, body mass index (BMI) and follow-up duration. There were 66 patients in the 0°≤LCEA<10° group and 66 patients in the 10°≤LCEA<18° group. The LCEA, anterior center-edge angle (ACEA), T?nnis angle, femoral head extrusion index, femoro-epiphyseal acetabular roof (FEAR) index, femoral anteversion angle, West Ontario and McMaster University (WOMAC) index and International Hip Outcome Tool (iHOT-12) were compared among the three groups before operation and the last follow-up.Results:In the preoperative 18°≤LCEA<25° group, three of 33 patients (9.1%) had LCEA, because the only imaging feature suggested acetabular dysplasia, while other parameters were evaluated within the normal range. There were 17 patients with ACEA <20° (51.5%), 24 patients (72.7%) with T?nnis angle >10°, 12 patients (36.4%) with ACEA <20° and T?nnis angle >10°. The positive rate of posterior wall signs in the 18°≤LCEA<25° group (72.7%) was lower than that in the 10°≤LCEA<18° group (77.3%) and the 0°≤LCEA<10° group (90.9%) with statistically significant difference (χ 2=6.417, P=0.040) at preoperation. The positive rate of cross sign (27.3%) and ischial spine sign (48.5%) in the 18°≤LCEA<25° group were higher than those in the 10°≤LCEA<18° group (10.6% and 18.2%, respectively, χ 2=7.002, P=0.030) and the 0°≤LCEA<10° groups (9.1% and 13.6%, respectively, χ 2=16.497, P<0.001). The FEAR index in the 18°≤LCEA<25° group (3.7±8.0) lower than that in the 10°≤LCEA<18° group (4.3±7.9) and the 0°≤LCEA<10° group (11.0±8.8) with significant difference ( F=12.703, P<0.001). In the 18°≤LCEA<25° group, postoperative LCEA increased from 20.4°±1.8° to 37.8°±7.1°, ACEA increased from 18.3°±7.8° to 36.3°±6.3°. T?nnis angle decreased from 12.7°±6.2° to -5.6°±9.2°, the femoral head extrusion index decreased from 22.9%±6.7% to 10.7%±12.2%, the WOMAC index decreased from 20.1±13.4 to 6.0±6.3, and the iHOT-12 score increased from 50.2±19.9 to 90.0±13.7. The above difference before and after surgery was statistically significant ( P<0.05). At the last follow-up, the WOMAC score in the 18°≤LCEA<25° group was 6.0±6.3, wich was less than 10°≤LCEA<18° group (9.3±9.6) and 0°≤LCEA<10° group (12.0±16.0) ( F=6.515, P=0.002). The iHOT-12 score in the 18°≤LCEA<25° group was 90.0±13.7, which was greater than 10°≤LCEA<18° group (77.7±17.3) and 0°≤LCEA<10° group (78.1±20.5) ( F=15.833, P<0.001). Conclusion:After 2 years follow-up, PAO significantly improved bone coverage of femoral head and hip function in patients with borderline DDH. Before surgery, we should pay attention to the comprehensive evaluation of different radiological parameters of the acetabulum, to make better preoperative planning.

Treatment of chronic osteoarthritic hip pain with phenol neurolysis of the obturator nerve Quadfen1 / Tratamento da dor crônica na osteoartrite do quadril com neurólise do nervo obturador com fenol Quadfen1

The conservative treatment of osteoarthritis (OA) of the hip is essentially symptomatic, seeking to relieve pain and optimize function. Despite presenting great clinical effect, hip arthroplasty may have restrictions, and in these situations, the neurolytic blockade of the anterior branch of the obturator nerve can be a therapeutic alternative, since it stops the afferent pain from the hip joint. Objective: To describe the results of treating patients with severe OA of the hip by applying phenol to the obturator nerve. Method: Twelve consecutive patients with OA of the hip, refractory to conservative treatment, were recruited to have the obturator nerve localized through electrostimulation and blocked with phenol. They were evaluated in terms of pain intensity via the visual analogue scale (VAS), pressure dolorimetry in the medial and lateral gluteus medius, gluteus minimus, and piriformis, and quality of life by the Harris Hip Score (HHS) at baseline (BL) after 1 (M1), 2 (M2), and 6 months (M6). Results: The patients were between 30 and 72 years old with an avarege of 47.5 ± 1.7 years old, 5 of them were women. Three patients were excluded for not being able to come for follow up evaluations. VAS values vaieded from 8.2 ±.0.9 at BL to 6.6 ± 1.7 at M1, 6.5 ± 1.7 at M2, and 7.3 ± 1 in M6 (p=0.0094). As to the HHS, the values were BL:33.27 ± 2.9; M1:39.2 ± 6.4; M2:40.2 ± 8.1, and M6: 38.8 ± 9.7 in the final evaluation (p=0,040). For dolorimetry, non significant variation was BL: 11±5.7, M1: 7.9±2.2; M2: 10.9±5.6; M6: 8.1 ± 1.6 (p 0.69). Conclusion: The application of phenol to the anterior branch of the obturator nerve can be an alternative in the treatment of severe OA of the hip in patients with restrictions to Total Hip Replacement (THR), since it reduces pain and improves quality of life.

O tratamento conservador da osteoartrite (OA) do quadril é essencialmente sintomático, visando alívio da dor e otimização da funcionalidade. Apesar de apresentar grande efeito clínico, a artroplastia quadril pode ter restrições, nestas situações o bloqueio do ramo anterior do nervo obturador (RAO) pode ser uma alternativa terapêutica, uma vez que interrompe a aferência dolorosa da articulação do quadril. Objetivo: Descrever os resultados do tratamento de pacientes com OA grave do quadril por meio da aplicação de fenol no nervo obturatório. Método: Nove pacientes com OA de quadril resistente ao tratamento conservador que se apresentaram consecutivamente ao nosso serviço foram submetidos à aplicação de fenol no nervo obturatório com localização por meio de eletroestimulação e avaliados quanto a intensidade de dor pela escala visual analógica (EVA), dolorimetria de pressão e qualidade de vida pelo Haris Hip Score (HHS) após 01, 02 e 06 meses. Resultados: Foram selecionados 12 pacientes que preenchiam os critérios de inclusão e exclusão, destes, 3 foram excluídos após não conseguirem mais comparecer para as avaliações. Os valores médios de EVA variaram de 8,2 ±.0,9 na medida basal para 6,6 ± 1,7 ao final de um mês, 6,5 ± 1,7 ao final de dois meses e 7,3 ± 1 com 06 meses (p=0,0094). Quanto ao HHS, os valores foram 33,27 ± 2,9; 39,2 ± 6,4; 40,2 ± 8,1 e 38,8 ± 9,7, na avaliação final. A última variável analisada foi a Dolorimetria, onde foi realizada a média entre os valores atingidos pela avaliação com o dolorímetro no glúteo médio medial, glúteo médio lateral, glúteo mínimo e piriforme. Na avaliação inicial média de 11±5,7, 7,9±2,2 no final do primeiro mês, 10,9±5,6 no segundo e no 6º mês 8,1±1,6. Ao aplicarmos o teste ANOVA, não foi observado diferença estatística (p 0,69). Conclusão: A aplicação de Fenol em RAO pode ser uma alternativa no tratamento da OA de quadril grave em pacientes com restrições à realização de ATQ, pois implica em redução da dor e melhora da qualidade de vida.

WOMAC and SF-36: instruments for evaluating the health-related quality of life of elderly people with total hip arthroplasty. A descriptive study / WOMAC e SF-36: instrumentos para avaliar a qualidade de vida relacionada à saúde de idosos com artroplastia total de quadril. Um estudo descritivo

CONTEXT AND OBJECTIVES: Quality-of-life results have increasingly been evaluated among patients undergoing joint replacements. The objective of this study was to compare two assessment instruments for health-related quality of life (one generic and the other specific), among elderly patients undergoing total hip arthroplasty.DESIGN AND SETTING: Cross-sectional descriptive study in a reference hospital in the region of Campinas.METHODS: The subjects were 88 elderly outpatients aged 60 years or over who underwent primary total hip arthroplasty. Two instruments for assessing health-related quality of life were applied: the generic Medical Study 36-item Short-Form Health Survey (SF-36) and the specific Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Cronbach's alpha and the ceiling and floor effects of the instruments were evaluated.RESULTS: The scores from both instruments showed that issues of a physical nature affected these elderly people's quality of life most. The pain and stiffness dimensions of WOMAC showed ceiling effects and only the functional capacity and pain dimensions of the SF-36 did not show the ceiling effect. The SF-36 presented floor effects in the dimensions of physical and emotional aspects. Cronbach's alpha was considered satisfactory in both instruments (α > 0.70).CONCLUSIONS: The floor and ceiling effects that were observed suggest that these instruments may present some limitations in detecting changes to the majority of the SF-36 dimensions, except for functional capacity and pain, and to the pain and stiffness dimensions of WOMAC, when applied to elderly people with total hip arthroplasty.

CONTEXTO E OBJETIVO: Os resultados sobre a qualidade de vida têm sido cada vez mais avaliados em pacientes submetidos a substituições articulares. Este estudo objetivou comparar dois instrumentos de avaliação de qualidade de vida relacionada à saúde (um genérico e outro específico), em pacientes idosos submetidos a artroplastia total de quadril.TIPO DE ESTUDO E LOCAL: Estudo descritivo transversal em hospital de referência da região de Campinas.MÉTODOS: Os sujeitos foram 88 pacientes idosos ambulatoriais, com 60 anos ou mais, submetidos a artroplastia total de quadril primária. Foram aplicados dois instrumentos de avaliação de qualidade de vida relacionada à saúde: Medical Study 36-item Short-Form Health Survey (SF-36) (genérico) e Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (específico). O coeficiente alfa de Cronbach e os efeitos teto e chão dos instrumentos foram avaliados.RESULTADOS: Os escores de ambos os instrumentos mostraram que as questões de natureza física são as que mais afetam a qualidade de vida desses idosos. As dimensões dor e rigidez do WOMAC apresentaram efeito teto e apenas as dimensões capacidade funcional e dor do SF- 36 não mostraram o efeito teto. O SF-36 apresentou efeito de chão nas dimensões: aspectos físicos e aspectos emocionais. O coeficiente alfa de Cronbach foi considerado satisfatório nos dois instrumentos (α > 0.70).CONCLUSÕES: A constatação dos efeitos chão e teto sugere que esses instrumentos podem apresentar algumas limitações, quando aplicados em idosos com artroplastia total de quadril, para detectar alterações na maioria das dimensões do SF-36, exceto capacidade funcional e dor, e nas dimensões dor e rigidez do WOMAC.

Relationship between brucellosis arthritis of the hip and femoral head necrosis / 中华地方病学杂志

Objective To investigate the relationship between brucellosis arthritis of the hip and femoral head necrosis.Methods In August 2007 to August 2013,16 diagnosed and hospitalized patients with brucellosis complicated with femoral head necrosis in Heilongjiang Land Reclamation Bureau General Hospital were chosen as the objects of observation,and the patients' hospitalization information was analyzed retrospectively.Patients' medical records were investigated and analyzed.Observations included general condition of the patient,clinical symptoms and signs,imaging,pathology,treatment and curative effect.Results All the 16 patients had definite clinical manifestations of hip arthritis and femoral head necrosis including hip pain,limited mobility,positive 4 test,limp or bedridden,and sick limb muscle atrophy.Imaging examination:X-ray computer tomography (CT) showed cystic change and deformation collapse of femoral head.Magnetic resonance imaging(MRI) showed low signal on weighted T1 images,high signal on weighted T2 and soft tissue granulation hyperplasia could be seen in the hip joint.Pathological examination:most femoral bone tissue necrosis,dissolved,bone cells disappeared,a few bone cells present,and some fibrous tissue hyperplasia.Patients were treated with antibiotics according to the treatment principles of brucellosis,and the effect was obvious.Conclusions There is a causal relationship between brucellosis arthritis of the hip and femoral head necrosis.Therefore,positive and effective treatment of brucellosis arthritis of the hip in the early stages is crucial to prevent the occurrence of femoral head necrosis.

Effects of femoral offset reconstruction or non-reconstruction on hip joint function in total hip arthroplasty / 中国组织工程研究

BACKGROUND:Femoral offset reconstruction is significant for recovering strength of abductor and the balance of soft tissue tension surrounding hip joint, maintaining joint stabilization, restoring joint function, reducing limping after replacement, decreasing prosthetic abrasion, and the incidence of joint prosthesis dislocation. OBJECTIVE:To discuss effect of femoral offset reconstruction on hip joint function in total hip arthroplasty. METHODS:We comparatively analyzed 20 patients (20 hips) undergoing the modular prosthesis (S-ROM) total hip arthroplasty and 19 patients (20 hips) undergoing the one modular prosthesis (Corail) total hip arthroplasty at the same time. According to Harris hip score and radiography results, hip joint function and femoral offset reconstruction rate were comparatively studied in both groups. RESULTS AND CONCLUSION:No infection, fracture, dislocation, deep venous thrombosis or neurovascular injury occurred in either group. Clinical fol ow-up results:In the modular prosthesis and one modular prosthesis groups, there was no significant difference in preoperative Harris hip score between the femoral offset reconstruction and non-reconstruction groups (P>0.05). At 12 months and the latest fol ow-up, the Harris hip score was higher in the patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P0.05). These results indicated that functional recovery and the range of abduction were better in patients with femoral offset reconstruction than those without femoral offset reconstruction. Modular prosthesis has a high rate of femoral offset reconstruction.

Mid-to long-term clinical outcome of Bernese periacetabular osteotomy in adolescents and young adults with develop-mental dysplasia of the hip / 中华骨科杂志

Objective To discuss the mid?to long?term results and possible prognostic factors of Bernese periacetabu?lar osteotomy for adolescents and young adults with developmental dysplasia of the hip. Methods Bernese periacetabular os?teotomy was performed on 162 patients (171 hips) with hip dysplasia from August 1997 to July 2009. Follow?up data was ac?quirable completely in 123 cases (137 hips), including 30 males (33 hips) and 93 females (104 hips). Age of surgery was 12-48 years (average 27.1 years). The X?ray radiographs and Harris scores were recorded preoperatively and at the last follow?up. The lateral center?edge angle (LCE), acetabular incline angle (AI), continuity of Shenton's line were also recorded. The grades of the hip osteoarthritis were classified by T?nnis classification. Insufficient corrections of osteotomy, excessive corrections of osteotomy, nonunion of the pubis, nerve injuries, and vascular injuries were recorded as complications. Results All the con?tactable cases was followed up again in June and July in 2014. Follow?up duration was 5-17 years (mean, 8.1 years). The LCE angle improved from 7.13° ± 8.86° preoperatively to 30.17° ± 14.98° at the final follow?up. The T?nnis acetabular incline angle decreased from 27.84° ± 12.85° preoperatively to 7.06° ± 10.58° at the final follow?up. The continuity of Shenton's line was in?tact in 106 cases postoperatively, compared with 87 cases preoperatively. Harris score improved from 83.34±9.82 preoperative?ly to 92.79±7.05 at the last follow?up. There was significant correlation between preoperative Harris score and Harris score at the last follow?up. Early complications were observed in 15 cases (15 hips), along with 17 cases (17 hips) of progressions of hip osteoarthritis. Survival rate of the hip at the last follow?up was 97.8%. Conclusion Bernese periacetabular osteotomies can significantly improve bone coverage and joint function of hip dysplasia patients with low rate of short?term complications. Further?more, there was little osteoarthritis progression observed, with good survival rate of the joint in mid?to long?term follow?up. Lower pre?operative Harris scores and higher pre?operative T?nnis classifications are important prognostic factors for post?operative pain.

Conceitos atuais em osteoartrite / Current concepts in osteoarthritis

A osteoartrite (OA), forma mais comum de doença articular, afeta principalmente quadris, joelhos, mãos e pés, levando a grande incapacidade e perda de qualidade de vida, sobretudo na população idosa. A importância desta doença cresce a cada ano, na medida em que observamos uma tendência de envelhecimento da população brasileira, com grande aumento da população idosa em relação aos mais jovens. O progressivo entendimento da fisiopatologia da OA, a percepção de que o processo não é puramente mecânico e/ou de envelhecimento, e o esclarecimento das vias inflamatórias envolvidas levaram, recentemente, à aplicação clínica de vários outros medicamentos e medidas. Esta atualização tem como objetivo expor os mais recentes conceitos sobre a fisiopatologia e tratamento da OA.

Osteoarthritis (OA), the most common form of joint disease, affects mainly the hips, knees, hands and feet, leading to severe disability and loss of quality of life, particularly in the elderly population. Its importance grows every year with the aging of the population, with a large increase in the elderly population compared to younger patients. The progressive understanding of the pathophysiology of OA, the perception that the process is not purely mechanical and/or aging, and clarification of the inflammatory pathways involved led recently to the clinical application of various drugs and other measures. This update aims to expose the current concepts on the pathophysiology and treatment of OA.
