Translation and Cultural Adaptation to Portuguese of the Long Head of Biceps Tendon Score / Tradução e adaptação cultural à língua portuguesa do Long Head Biceps Score

Abstract Objective To translate and culturally adapt the Long Head of Biceps Tendon (LHB) score into Brazilian Portuguese. Methods The process involved translations by professionals fluent in the target language, followed by independent back translations. Next, a committee compared the original and translated versions, pretested the final version, and concluded it. Results We translated and adapted the questionnaire according to the proposed methodology. In the first version in Portuguese (VP1) there was divergence regarding the translation of twelve terms. Compared to the original version, the back translation of VP1 presented eight diverging terms. A committee prepared a second version in Portuguese (VP2) and applied it to a pretest group consisting of 30 participants. Finally, we conceived the third version in Portuguese, called LHB-pt. Conclusion The translation and cultural adaptation into Brazilian Portuguese of the LBH score was successfully accomplished.

Abstract: Introduction: plantar fasciitis or fasciosis is a cause of foot pain with cases resistant to conservative treatment. Surgery is reserved for patients who have not responded to conservative treatment, shock waves, or corticosteroid injections. The aim of this publications is to carry out a systematic review of the available literature and to describe a specific technique for the treatment of plantar fasciosis consisting of the longitudinal tearing of the plantar aponeurosis assisted with ultrasound. Material and methods: a systematic search was carried out for previous publications on longitudinal tenotomy in the treatment of plantar fasciitis. The Medical Subject Headings (MeSH) terms «Curettage¼, «Tenotomy¼ and «Plantar Fasciitis¼ were included. The electronic search included PubMed, Embase, Cochrane central register of controlled trials, Trip database, and National Institute for Health and Care Excellence (NICE) databases. A detailed description of the technique was included with the intention that it can be reproduced. Conclusion: longitudinal tenotomy represents an alternative for the treatment of plantar fasciitis. It is based on the extrapolation of knowledge in the Achilles tendon territory with a supporting pathophysiological basis. It is a non-invasive technique that can be performed on an outpatient basis and that would allow the rapid incorporation of the patient to their activities. Longitudinal tenotomy would prevent the patient from undergoing major surgeries.

Biceps tenotomy or tenodesis in association with rotator cuff repair: is there an influence on functional results? A retrospective cohort study

ABSTRACT BACKGROUND: Instability or tears of the long head of the biceps tendon (LHBT) may be present in more than 35% of rotator cuff repairs (RCR). OBJECTIVE: To compare clinical results from patients undergoing arthroscopic RCR, according to the procedure performed at the LHBT. DESIGN AND SETTING: Retrospective cohort study designed at the shoulder and elbow clinic of Instituto de Ortopedia e Traumatologia, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil. METHODS: Functional results among patients were compared using the American Shoulder and Elbow Surgeons (ASES) and University of California Los Angeles (UCLA) scales, according to the LHBT approach adopted: no procedure, tenotomy or tenodesis. RESULTS: We evaluated 306 shoulders (289 patients): 133 underwent no procedure at the LHBT, 77 tenotomy and 96 tenodesis. The ASES scale at 24 months showed no difference (P = 0.566) between the groups without LHBT procedure (median 90.0; interquartile range, IQR 29), tenotomy (median 90.0; IQR 32.1) or tenodesis (median 94.4; IQR 22.7); nor did the UCLA scale (median 33; IQR 7 versus median 31; IQR 8 versus median 33; IQR 5, respectively, P = 0.054). The groups differed in the preoperative functional assessment according to the ASES and UCLA scale, such that the tenodesis group started from higher values. However, there was no difference in pre and postoperative scores between the groups. CONCLUSION: Tenodesis or tenotomy of the LHBT, in the sample analyzed, did not influence the clinical results from RCR, as assessed using the ASES and UCLA scales.

Evaluation of Biceps Tenotomy or Tenodesis on Fatty Infiltration of the Biceps Muscle / Avaliação da tenotomia ou tenodese bicipital na infiltração gordurosa do músculo bíceps

Abstract Objective The objective of the present study was to determine whether there is fatty infiltration (FI) of the biceps brachii muscle mass after tenotomy or tenodesis for the treatment of tendon injuries in the long head of the biceps and to establish a relationship between FI with changes in the length of muscle fibers. Methods Clinical and imaging analysis of 2 groups of patients (biceps tenodesis [16 patients] and biceps tenotomy [15 patients]). In both groups, we compared the findings on the contralateral side of each patient (control group). All patients had undergone unilateral biceps tenodesis or tenotomy, with postoperative follow-up of > 1 year. Magnetic resonance imaging (MRI) was performed on both arms of each patient following a specific protocol. Strength of elbow flexion was measured with a manual dynamometer, and the results were subjected to statistical analysis. Results The mean postoperative period before the MRI was 5 years, and no case of FI was observed in the anterior compartment of either arm of the evaluated patients. Seven patients had moderate or severe deformity in the operated arm. We found no significant relationship between arm deformity (p = 0.077), flexion strength percentage (p = 0.07) or pain on palpation of the bicipital groove (p = 0.103). Conclusion None of the evaluated patients had evidence of FI in the muscle mass of the anterior arm compartment after the procedures. It was not possible to establish a correlation between the discrepancy of the biceps muscle length measured by MRI and the presence of FI in the anterior compartment of the arm.

Resumo Objetivo O objetivo do presente estudo foi determinar a existência de infiltração gordurosa (IG) na massa muscular do bíceps braquial após a tenotomia ou tenodese para tratamento de lesão no tendão da cabeça longa do bíceps e estabelecer uma relação entre a IG e alterações no comprimento das fibras musculares. Métodos Análise clínica e de imagens de 2 grupos de pacientes (submetidos à tenodese do bíceps [16 indivíduos] ou tenotomia do bíceps [15 indivíduos]). Nos dois grupos, os achados foram comparados àqueles do lado contralateral de cada indivíduo (grupo controle). Todos os pacientes foram submetidos à tenodese ou tenotomia unilateral do bíceps, com acompanhamento pós-operatório > 1 ano. Exames de ressonância magnética (RM) foram realizados em ambos os braços de cada paciente de acordo com um protocolo específico. A força de flexão do cotovelo foi medida com dinamômetro manual e os resultados foram submetidos à análise estatística. Resultados O período pós-operatório médio antes da realização da RM foi de 5 anos, e nenhum caso de IG foi observado no compartimento anterior de ambos os braços dos pacientes avaliados. Sete pacientes apresentaram deformidade moderada ou grave no braço operado. Não houve relação significativa entre deformidade do braço (p = 0,077), percentual de força de flexão (p = 0,07) ou dor à palpação do sulco bicipital (p = 0,103). Conclusão Nenhum dos pacientes avaliados apresentou evidência de IG na massa muscular do compartimento anterior do braço após os procedimentos. Não foi possível estabelecer uma correlação entre a discrepância do comprimento do músculo bíceps, medido à RM, e a presença de IG no compartimento anterior do braço.

The relevant anatomy of the biceps tendon when performing tenodesis in Filipino cadaveric specimens

BACKGROUND@#Biceps tenodesis is a technique frequently performed in shoulder surgeries. Various techniques have been described, but there is no consensus on which technique restores the length-tension relationship. Restoration of the physiologic length-tension relationship has been correlated to better functional outcomes, such as decreased incidence of residual pain or weakness of the biceps. The objective of this study was to measure the anatomic relationship of the origin of the biceps tendon with its zones in the upper extremity. This would provide an anatomic guide or an acceptable placement of the tenodesis to reestablish good biceps tension during surgery@*METHODS@#The study used nine adult cadavers (five males, four females) from the [withheld for blinded review]. Nine shoulder specimens were dissected and markers were placed at five points along each biceps tendon: (1) Labral origin (LO) (2) Superior bicipital groove (SBG) (3) Superior border of the pectoralis tendon (SBPMT) (4) Musculotendinous junction (MTJ) and (5) Inferior border of the pectoralis tendon (IBPMT). Using the origin of the tendon as the initial point of reference, measurements were made to the four subsequent sites. The humeral length was recorded by measuring the distance between the greater tuberosity and the lateral epicondyle as well as the tendon diameter at the articular surface.@*RESULTS@#The intraclass correlation coefficient was excellent across all measures. A total of nine cadavers were included. Mean age of patients was 66.33 years old, ranging from 52-82 years old. These were composed of five male and four female cadavers. The mean tendon length was 24.83mm ± 4.32 from the origin to the superior border of the bicipital groove, 73.50mm ± 6.96 to the Superior Border Pectoralis Major Tendon, 100.89mm ± 6.88 to the Musculotendinous Junction, and 111.11mm ± 7.45 to the Inferior Border Pectoralis Major Tendon. The mean tendon diameter at the articular origin was 6.44mm ± 1.76.@*CONCLUSION@#This study provided measurement guidelines that could restore the natural length-tension relationship during biceps tenodesis using the interference screw technique in Filipinos. A simple method of restoring a normal length-tension relationship is by doing tenodesis close to the articular origin and creating a bone socket of approximately 25mm in depth, using the superior border of the bicipital groove as a landmark.

Supraspinatus Muscle Tendon Lesion and Its Relationship with Long Head of the Biceps Lesion / Lesão do tendão do músculo supraespinal e sua relação com a lesão do tendão da cabeça longa do bíceps

Abstract Objective To identify the clinical, radiological, and arthroscopic correlation of long head of the biceps tendon injuries and their influence on pain when associated with rotator cuff injuries. Methods Between April and December 2013, 50 patients were evaluated, including 38 (76%) women and 12 (24%) men, with a mean age of 65.1 years old. The patients were operated by the Shoulder and Elbow Group, Discipline of Sports Medicine, Orthopedics and Traumatology Department, Universidade Federal de São Paulo. The subjects underwent repair of the rotator cuff lesion with clinical, radiological and/or arthroscopic evidence of involvement of the long head of the biceps tendon. Results An association between pain at palpation of the intertubercular groove of the humerus and high-grade partial lesions (partial rupture of the tendon affecting more than 50% of its structure) was observed at the arthroscopy (p = 0.003). There was also an association between the high-grade lesion of the long head of the biceps and injury to the supraspinatus muscle tendon (p < 0.05). For each centimeter of the supraspinatus muscle tendon injury, the patient presented a 1.7 higher probability of having a high-grade lesion at the long head of the biceps. Conclusion Pain at the anterior shoulder region during palpation of the intertubercular groove of the humerus may be related to high-grade lesions to the long head of the biceps. Rotator cuff injury and its size are risk factors for high-grade injuries to the long head of the biceps tendon.

Resumo Objetivo Identificar a correlação clínica, radiológica, e artroscópica das lesões do tendão da cabeça longa do bíceps e sua influência na dor do paciente quando associada às lesões do manguito rotador. Métodos Entre abril e dezembro de 2013, foram avaliados 50 pacientes, sendo 38 (76%) do sexo feminino e 12 (24%) do sexo masculino, com idade média de 65,1 anos. Os pacientes foram operados pelo Grupo de Ombro e Cotovelo da Disciplina de Medicina Esportiva do Departamento de Ortopedia e Traumatologia da Universidade Federal de São Paulo. Os indivíduos foram submetidos a reparo da lesão do manguito rotador com evidência clínica, radiológica e/ou artroscópica de acometimento do tendão da cabeça longa do bíceps. Resultados Observou-se associação entre dor à palpação do sulco intertubercular do úmero com lesão parcial de alto grau (ruptura parcial acometendo mais de 50% do tendão) na artroscopia (p = 0,003). Encontramos ainda uma associação entre a lesão de alto grau da cabeça longa do bíceps e a lesão do tendão do músculo supraespinal (p < 0,05), sendo que, para cada centímetro de lesão do tendão do músculo supraespinal, o paciente apresenta probabilidade 1,7 maior de ter uma lesão de alto grau da cabeça longa do bíceps. Conclusão A dor na região anterior do ombro à palpação do sulco intertubercular do úmero pode estar relacionada às lesões de alto grau da cabeça longa do bíceps. A lesão do manguito rotador e o seu tamanho são fatores de risco para lesão de alto grau do tendão da cabeça longa do bíceps.

Effect of low intensity photobiomodulation associated with norbixin-based poly (hydroxybutyrate) membrane on post-tenotomy tendon repair. In vivo study

Abstract Purpose: To evaluate the in vivo response of photobiomodulation therapy associated with norbixin-based poly(hydroxybutyrate) membrane (PHB) in tenotomized calcaneal tendon. Methods: Thirty rats were randomly allocated to six groups (n=5 each): LED groups (L1, L2 and L3) and membrane + LED groups (ML1, ML2 and ML3). The right calcaneal tendons of all animals were sectioned transversely and were irradiated with LED daily, one hour after surgery every 24 hours, until the day of euthanasia. At the end of the experiments the tendons were removed for histological analysis. Results: The histological analysis showed a significant reduction in inflammatory cells in the ML1, ML2 and ML3 groups (p=0.0056, p=0.0018 and p<0.0001, respectively) compared to those in the LED group. There was greater proliferation of fibroblasts in the ML1 (p<0.0001) and L3 (p<0.0001) groups. A higher concentration of type I collagen was also observed in the ML1 group (p=0.0043) replacing type III collagen. Conclusion: Photobiomodulation in association with norbixin-based PHB membrane led to control of the inflammatory process. However, it did not favor fibroblast proliferation and did not optimize type I collagen formation in the expected stage of the repair process.

Prevalence of popeye deformity after long head biceps tenotomy and tenodesis / Predomínio da deformidade de popeye após tenotomia e tenodese da cabeça longa do bíceps

ABSTRACT Objective: To evaluate whether body mass index (BMI) 30 can be used as a cut-off point in decisions about whether or not to perform long head biceps (LHB) tenodesis, leading to a low rate of esthetic complaints, and to compare two tenodesis techniques. Methods: Ninety-six patients underwent shoulder arthroscopy where tenotomy was performed separately in patients with a BMI ≥30 and was followed by tenodesis when BMI <30. The patients were assessed on the basis of their personal perception of the deformity and by 3 independent observers. Results: The patient's perception of esthetic deformity in the arm was 15.6%. In the tenotomy group (12.5%) and in the tenodesis group (17.9%) - (p = 0.476). Patients with rocambole-like tenodesis perceived the deformity in 13.2% of cases, while patients with anchor tenodesis noticed the deformity 27.8% (p = 0.263) of the time. There was no statistical difference in the perception of deformity among the independent examiners. Conclusion: BMI 30 can be used as a cut-off point in decisions about whether or not to perform LHB tenodesis, leading to low rates of esthetic complaint by patients (12.5%). The rocambole-like tenodesis technique appears to be more able to avoid esthetic deformity of the arm after the LHB tenotomy according to the patients' observations. Level of evidence II, Prospective comparative study.

RESUMO Objetivo: Avaliar se índice de massa corporal (IMC) 30 pode ser utilizado como ponto de corte nas decisões sobre realizar ou não a tenodese da cabeça longa do bíceps (CLB), levando a um baixo índice de queixa estética, e comparar duas técnicas de tenodese. Métodos: Foram submetidos à cirurgia artroscópica no ombro 96 pacientes, sendo a tenotomia realizada de forma isolada nos pacientes com IMC ≥ 30 e seguida de tenodese quando IMC < 30. Os pacientes foram avaliados por sua percepção pessoal da deformidade e por três observadores independentes. Resultados: A percepção da deformidade estética no braço pelo paciente foi de 15,6%. No grupo tenotomia (12,5%) e no grupo tenodese (17,9%) - (p=0,476). Pacientes com tenodese rocambole perceberam a deformidade em 13,2% dos casos, enquanto os pacientes com tenodese em âncora a notaram em 27,8% das vezes (p=0,263). Não houve diferença estatística para a percepção da deformidade entre os examinadores independentes. Conclusão: IMC 30 pode ser usado como ponto de corte nas decisões sobre realizar ou não a tenodese da CLB, levando a baixos índices de queixa estética por parte dos pacientes (12,5%). A técnica de tenodese tipo rocambole parece ter mais capacidade de evitar a deformidade estética do braço após a tenotomia da CLB, conforme a observação dos pacientes (13,2%). Nível de evidência II, estudo prospectivo comparativo.

Tenotomy of the Gluteus Maximus in Total Hip Arthroplasty with Prevention of Sciatic Nerve Injury / Tenotomia do glúteo máximo em artroplastia total do quadril como prevenção de lesão do nervo ciático

Abstract The authors report a single case of complex primary hip total arthroplasty in a 34-yearold female patient with a 5.5 cm lower limb dysmetria, in whom a maximum gluteus tenotomy was performed in order to prevent sciatic nerve injury. The surgery was performed under electroneurophysiological monitoring of the fibular and tibial branches of the sciatic nerve, collecting pretenotomy, posttenotomy, and postarthroplasty reduction data. The findings demonstrate that the maximum gluteus tenotomy improved the motor response of the fibular component of the sciatic nerve.

Local treatment with ascorbic acid accelerates recovery of post-sutured Achilles tendon in male Wistar rats

Tendon rupture is a very frequent accident involving average people and high-performance athletes. Clinical studies describe tendon recovery as a painful and slow process involving different biochemical and histological events. Ascorbic acid (AA) is a potent antioxidant as well as an important cofactor for collagen synthesis. In the current study, we evaluated if local treatment with AA is able to promote tendon repair in tenotomized rats. Animals were submitted to Achilles tendon rupture followed by surgical suture. Control and AA groups received in loco injection of saline solution (0.9% NaCl) and 30 mM AA, respectively. Histological and functional recovery of Achilles tendon tissue was evaluated at 7, 14, and 21 days post-surgery. Hematoxylin/eosin staining and collagen fluorescence analysis showed intense disarrangement of tendon tissue in the saline group. Tenotomized animals also showed hypercellularity in tendon tissue compared with non-tenotomized animals. The Achilles functional index (AFI) showed a significant decrease of tendon functionality in tenotomized animals at 7, 14, and 21 days post-surgery. AA accelerated tissue organization and the recovery of function of the Achilles tendons. The beneficial effect of AA treatment was also observed in the organization of the collagen network. Data presented in the current work showed that in loco treatment with AA accelerated the recovery of injured Achilles tendon post-surgery.

Comparison of two different arthroscopic techniques for long head of biceps tendinitis / 中国骨伤

OBJECTIVE@#To compare clinical efficacy of arthroscopic tenodesis and tenotomy in treating biceps long head tendinitis.@*METHODS@#From January 2015 to January 2017, 40 patients with long head of the biceps tendinitis were randomly divided into tenotomy group (18 patients) and tenodesis group(22 patients). In tenotomy group, there were 6 males and 12 females with an average age of (62.2±6.1) yeas old, and the average course of disease was (8.5±2.2) months; while in tenodesis group, there were 8 males and 14 females with an average age of(60.5±6.3) years old, and the average course of disease was (8.1±2.3) months. Operative time and deformity of Popeye were compared between two groups, VAS score was used to evaluate degree of pain, and UCLA score was used to assess clinical effects before operation, 3, 6 and 12 months after operation.@*RESULTS@#Forty patients were followed up for 12 to 17 months with an average of(14.3±2.1) months. Eight patients occurred Popeye deformity in tenotomy group, and nobody in tenodesis group. There was significant difference between tenotomy group(40.55±7.51) min and tenodesis group(75.33±9.45) min. VAS score after operation at 3, 6 and 12 months were decreased than that of before operation, and VAS score in tenotomy group was lower than that of in tenodesis group at 3 months after operation(0.05). UCLA score at at 3, 6 and 12 months after operation in tenodesis group were increased than that of before operation, and UCLA score in tenotomy group was lower than that of in tenodesis group at 3 months after operation(0.05). According to UCLA score, 5 got excellent results, 10 moderate and 3 poor in tenotomy group, while 8 got excellent results, 12 moderate and 2 poor in tenodesis group, but without difference between two groups(χ² =0.057, =0.81).@*CONCLUSIONS@#Both of arthroscopic tenotomy and tenodesis in treating long head of the biceps tendinitis could receive good clinical effects, and early functional outcomes by arthroscopic tenotomy was better than that of tenodesis, but no difference in later period.

Histological Changes in Biceps Muscle after Tenotomizing the Biceps Long Head in a Rat Model

BACKGROUND: Popeye deformity is common after rupture of the biceps muscle's long head tendon. Herein, we report on histological changes in biceps brachii muscles following tenotomy of the long head biceps tendon. METHODS: Twelve Sprague-Dawley rats (12-week-old) underwent tenotomy of the long head biceps tendon in the right shoulder. At postoperative weeks 4, 7, and 10, the operative shoulders were removed by detaching the biceps brachii muscle from the glenoid scapula and humerus; the opposite shoulders were removed as controls. H&E staining was performed to elucidate histological changes in myocytes. Oil-red O staining was performed to determine fatty infiltration. Myostatin antibody immunohistochemistry staining was performed as myostatin is expressed by skeletal muscle cells during myogenesis. RESULTS: H&E staining results revealed no changes in muscle cell nuclei. There were no adipocytes detected. Compared with that of the control biceps, the cross-sectional area of the long head biceps was significantly smaller (p=0.00). Statistical changes in the total extent of the 100 muscle cells were significant (p=0.00). Oil-red O staining revealed no fatty infiltration. Myostatin antibody immunohistochemical staining revealed no significant difference between the two sides. CONCLUSIONS: Muscular changes after tenotomy of the long head biceps included a decrease in the size of the individual muscle cells and in relative muscle mass. There were no changes observed in muscle cell nuclei and no fatty infiltration. Moreover, there were no changes detected by myostatin antibody immunohistochemistry assay.

Outpatient Percutaneous Flexor Tenotomy for Diabetic Claw Toe Deformity with Ulcer / 대한족부족관절학회지

PURPOSE: Toe ulcers have been implicated as a causative factor in diabetic foot amputation. The aim of this study was to evaluate the outcomes of percutaneous needle flexor tenotomies of diabetic claw toes with ulcers or pending ulcers. MATERIALS AND METHODS: The authors undertook a retrospective chart review between January 2014 and June 2016 to identify those patients who underwent a percutaneous needle flexor tenotomy for diabetic claw toe deformities. We evaluated 54 toes in 42 patients. Twenty-four patients were female and the mean age at the time of operation was 57 years. The mean follow-up time was 11 months. Thirty-four patients (46 toes) had tip toe ulcers or pending ulcers and 8 patients (8 toes) had dorsal pending ulcers. All patients had palpable pulses and good capillary refill. RESULTS: Forty-three of 46 tip toe ulcers (93.5%) healed without significant complications and 8 dorsal ulcers showed no specific changes within 5 weeks. There were no recurrent ulcers at final follow-up. Four patients developed transfer lesion of the adjacent toe and needed subsequent tenotomy. CONCLUSION: Percutaneous needle tenotomy in an outpatient clinic was an effective and safe method for treating toe ulcers in neuropathic patients to offload the tip of the toe so that ulcer healing could occur.

Disorders of the long head of the biceps: tenotomy versus tenodesis / Lesões do cabo longo do bíceps: tenotomia versus tenodese

ABSTRACT Disorders of the long head of biceps tendon are common in clinical practice. Their causes could be degenerative, inflammatory, instability (subluxation or luxation) or traumatic. They are generally associated to other diseases of the shoulder, mainly rotator cuff injuries. Currently, there is controversy in the literature regarding the indications for surgical treatment and the choice of the best technique for each case, due to the possibility of esthetic deformity, loss of muscle strength, and residual pain. The objective of this study was to identify the indications for surgical treatment, the best surgical technique, and the advantages and disadvantages of each technique described in the orthopedic literature for the treatment of long head of biceps tendon injuries. A revision of the orthopedic medical literature on the following databases: Biblioteca Regional de Medicina (BIREME), Medline, PubMed, Cochrane Library and Google Scholar, comprising articles published in the period from 1991 to 2015.

RESUMO As lesões da cabeça longa do tendão bicipital (CLB) são comuns na prática clínica e podem ter causas degenerativas, inflamatórias, instabilidades (subluxação ou luxação) ou traumáticas. Geralmente, elas estão associadas a outras doenças do ombro, principalmente a lesões do manguito rotador. Atualmente, existem controvérsias quanto às indicações dos tratamentos cirúrgicos e à escolha da melhor técnica para cada caso, devido à possibilidade de deformidade estética, perda da força muscular e dor residual. O objetivo deste estudo foi identificar as indicações do tratamento cirúrgico, a melhor técnica cirúrgica e as vantagens e desvantagens de cada técnica descritas na literatura médica ortopédica no tratamento das lesões da CLB. Foi realizada revisão da literatura médica ortopédica disponível na base de dados da Biblioteca Regional de Medicina (BIREME), Medline, PubMed, Cochrane Library e Google Scholar, incluindo artigos publicados no período de 1991 a 2015.

Resumen: Objetivo: Determinar el tiempo de curación del tendón de Aquiles en pacientes pediátricos tratados mediante tenotomía de Aquiles con método Ponseti en el Hospital Shriners para Niños de México, AC. Material y métodos: Estudio experimental, analítico, prospectivo, longitudinal de pacientes con diagnóstico de pie equino varo aducto congénito idiopático en tratamiento con método Ponseti con evaluación estática y dinámica mediante ecógrafo en tiempo real Siemens Diagnostic Ultrasound System Sonoline 650 con transductor lineal de 10.5 mHz seriada del tendón de Aquiles previa a la tenotomía y a las tres, seis, nueve y 12 semanas tras el tratamiento quirúrgico. Resultados: Se obtuvo una muestra de 23 pacientes, 16 masculinos y siete femeninos, 16 con patología bilateral y siete unilateral, para un total de 39 pies, 18 derechos y 21 izquierdos, con una media de edad de 8.3 ± 2.3 meses. Previamente a la tenotomía, la anchura en corte longitudinal ultrasonográfico media fue de 2.7 ± 0.42 mm; en la semana tres, la media fue 3 ± 0.39 mm; a las seis semanas, 2.92 ± 0.36 mm; el ultrasonido de las nueve semanas reportó media de 2.84 ± 0.38 mm y a las 12 semanas, 2.82 ± 0.39 mm. Se compararon mediante t de Student el ancho prequirúrgico y a las 12 semanas, sin encontrarse diferencia p > 0.03. Conclusiones: La valoración ecográfica muestra integridad a las tres semanas posteriores a la tenotomía de Aquiles. Sin embargo, la reparación completa se logra a las 12 semanas.

Abstract: Objective: The aim of this study was to determine the healing time of Achilles tendon in pediatric patients treated with Achilles tenotomy with the Ponseti method in Shriners Children's Hospital of Mexico, AC. Material and methods: Experimental, analytical, prospective, longitudinal study of patients with a diagnosis of idiopathic congenital clubfoot treated with the Ponseti method with serial static and dynamic evaluation by ultrasound in real time with a Siemens Diagnostic Ultrasound System Sonoline 650, linear transducer 10.5 MHz of Achilles tendon before tenotomy and at three, six, nine and 12 weeks after the surgical treatment. Results: A sample of 23 patients, 16 male and seven female, 16 with unilateral and seven with bilateral pathology was obtained, for a total of 39 feet, 18 right and 21 left, with a mean age of 8.3 ± 2.3 months. Before tenotomy, the width was 2.7 ± 0.42 mm; in week three, the average was 3 ± 0.39 mm; at six weeks, 2.92 ± 0.36 mm; ultrasound at nine weeks reported an average of 0.38 ± 2.84 mm, and 2.82 ± 0.39 mm at twelve weeks. They were compared using Student's t presurgical width and at twelve weeks, without finding difference p > 0.03. Conclusions: Although there is integrity at three weeks after Achilles tenotomy, complete repair is achieved at 12 weeks.

Surgical treatment of congenital torticollis, at the shriners hospital, mexico city / Tratamento cirúrgico de torcicolo congênito no hospital shriners, cidade do méxico / Tratamiento quirúrgico de tortícolis congénito en el hospital shriners, ciudad de méxico

ABSTRACT Objective: This study aims to evaluate the outcome of surgical treatment of congenital torticollis in our hospital. Methods: We collected the medical records of all patients diagnosed with congenital torticollis in the last 3 years at Shriners Hospital, Mexico City. The cases of congenital torticollis treated with surgery were selected and we evaluated the type of surgical technique, bleeding, time of surgery and complications, as well as the associated diagnoses of hip dysplasia. Results: We found 11 patients, of whom 7 met the inclusion criteria. Three women and four men with mean age of 10.7 years, five of whom had right, and two left side affections. All were surgically treated, five with unipolar and two with bipolar release. The surgery time was similar in both techniques and no complications were found in any of the groups. In two cases there were associated diagnoses, Klippel-Feil syndrome and congenital talipes equinovarus (CTEV) in one and psychomotor retardation in another. No association was found with hip dysplasia. All patients had improved range of movement and head tilt. There were no complications related to the surgical procedure or need for reintervention in our patients. Conclusions: Surgical treatment of congenital torticollis by uni- or bipolar release is an effective and safe method for these patients, presenting aesthetic and functional benefits.

Local inhibition of nitrergic activity in tenotomized rats accelerates muscle regeneration by increasing fiber area and decreasing central core lesions

Muscular atrophy is a progressive degeneration characterized by muscular proteolysis, loss of mass and decrease in fiber area. Tendon rupture induces muscular atrophy due to an intrinsic functional connection. Local inhibition of nitric oxide synthase (NOS) by Nω-nitro-L-arginine methyl ester (L-NAME) accelerates tendon histological recovery and induces functional improvement. Here we evaluate the effects of such local nitrergic inhibition on the pattern of soleus muscle regeneration after tenotomy. Adult male Wistar rats (240 to 280 g) were divided into four experimental groups: control (n=4), tenotomized (n=6), vehicle (n=6), and L-NAME (n=6). Muscular atrophy was induced by calcaneal tendon rupture in rats. Changes in muscle wet weight and total protein levels were determined by the Bradford method, and muscle fiber area and central core lesion (CCL) occurrence were evaluated by histochemical assays. Compared to tenotomized (69.3±22%) and vehicle groups (68.1%±17%), L-NAME treatment induced an increase in total protein level (108.3±21%) after 21 days post-injury. A reduction in fiber areas was observed in tenotomized (56.3±1.3%) and vehicle groups (53.9±3.9%). However, L-NAME treatment caused an increase in this parameter (69.3±1.6%). Such events were preceded by a remarkable reduction in the number of fibers with CCL in L-NAME-treated animals (12±2%), but not in tenotomized (21±2.5%) and vehicle groups (19.6±2.8%). Altogether, our data reveal that inhibition of tendon NOS contributed to the attenuation of atrophy and acceleration of muscle regeneration.

Problem Solving for Failed Superior Labrum Anterior to Posterior (SLAP) Repair / 대한정형외과학회잡지

Stiffness and pain are major causes of failed superior labral anterior to posterior (SLAP) repair. The term, ‘failed SLAP repair’, can be defined as stiffness or pain without rotator cuff tears, acromio-clavicular pathology, arthritis, impingement syndrome, and other shoulder diseases. Moreover, it does not respond to conservative management. Generally, for failed SLAP repair, the initial conservative management includes physical therapy, strengthening exercise, oral medications, and injections. In addition, with failed conservative treatment, surgical intervention can be carried out. Surgical indications must be in consideration with patients' age, mechanism of injury, stability of the lesion, activity, former history of sports activity, and types of sports. Surgical treatments include debridement, SLAP repair, biceps tenodesis and tenotomy. However, each type of surgical method is controversial on both indications and prognosis. Surgical treatment on SLAP lesion is increasing, and studies on failed SLAP repair are expanding. The recommended first line therapy for failed SLAP lesion is conservative management, and with limited and thorough indications, surgical treatment yields good results, depending on concurrent lesions. However, authors recommend that it is important to seek for adjacent lesions prior to the initial SLAP repair to decrease failed SLAP repair.
