RESUMO

OBJECTIVES: Core muscle injury is a debilitating condition that causes chronic groin pain in athletes, particularly common in soccer players. The condition is characterised by pain in the inguinal region and can lead to a significant number of absences from high-intensity physical activity. It is caused by repetitive overload without proper counterbalance from the abdominal muscles, hip flexors, and adductors in susceptible athletes. Surgical indications for core muscle injury consider cases where non-surgical treatments have not provided sufficient relief. The aim of this study was to assess the results of surgical intervention for core muscle injury using the technique employed by the Sports Medicine Group of (Institute of Orthopedics and Traumatology of Hospital das Clínicas - Universidade de São Paulo). The procedure involves releasing the anterior portion of the tendon of the rectus abdominis muscle near the pubic symphysis, along with proximal tenotomy of the adductor longus muscle tendon. METHODS: This study utilised a consecutive historical cohort analysis of the medical records of 45 male athletes, of which, 75.6% were professional soccer players, who underwent surgical treatment between January 1, 2002, and December 31, 2021. The participants included active athletes aged between 18 and 40 years, with a mean age of 23.9 years, and were diagnosed with myotendinous core muscle injury. These athletes experienced pain in the pubic symphysis and adductor tendon region and had previously undergone medical treatment and physical therapy for a duration of three to six months without significant improvement. RESULTS: The average time for athletes to return to sport after surgery was 135 days, with a majority of participants being soccer and futsal players. The surgical intervention yielded promising results, with a positive correlation between unilateral injuries and the time taken to return to sport. The complication rate was low, at 6.7%. Notably, the rate of symptom resolution was high, at 93.3%. Furthermore, the analysis indicated that the player's position on the field significantly influenced the discharge period, suggesting that the game position plays a role in the recovery process. CONCLUSION: The combined surgical procedure involving the release of the rectus abdominis tendon and adductor longus muscle tenotomy demonstrates favourable outcomes for athletes with core muscle injury. This study provides strong support for the effectiveness of this surgical approach in managing the condition and offers a potential path to recovery and return to sports activities. STUDY DESIGN: Cross-sectional study.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

We described the case of a 12-year-old patient who presented isolated contracture of the left rectus femoris muscle with subsequent traumatic rupture of the distal myotendinous junction; for this reason she did not present contracture in extension of the knee but she presented dynamic contracture in flexion of the hip (Ely positive test), which generated great impact on walking. Surgical management with tenotomy of the anterior rectum was performed, obtaining good results. This pathology has low incidence and it has been reported little in the literature, so it is important to suspect it. We provide an updated diagnostic and therapeutic approach.

RESUMO

Background: Flexural deformities are anatomical deviations, in varying degrees, of one or more joints, and may have a congenital or acquired origin. Congenital contracture of the deep digital flexor tendon (DDFT) affects newborn calves and results in hyperflexion of the metacarpal-phalangeal joint, which in severe cases means that the animal must support its own weight on its fetlock joints. The aim of this study is to report the rapid and successful result of applying bilateral total tenotomy technique on a newborn bovine that had been diagnosed with severe bilateral DDFT contracture in the thoracic limbs. Case: A 3-week-old male bovine with a history of difficulty in maintaining a quadrupedal position was attended at the Veterinary Hospital of the Federal University of Tocantins. The animal had severe bilateral locomotor alterations in the thoracic members to the point that he walked on his fetlock joints. The physical examination revealed clinical parameters within the normal range. However, the locomotor system examination showed severe flexor deformity in the bilateral metacarpal-phalangeal joints, and the limbs were being supported on the dorsal face of the fetlock joints, which presented ulcerations, and was suggestive of a shortening of the DDFT. Based on the patients history and clinical examination, as well as the severity of the tendon contractures, surgical treatment using the DDFT bilateral total tenotomy technique was decided upon. Postoperative treatment consisted of 2.5 mg/kg of enrofloxacin intramuscularly (IM), SID, for 5 days and 0.5 mg/kg meloxicam via IM, SID, for 3 days; as well as a dressing (cotton, medical bandage and a PVC mold) on the thoracic limbs to provide support and allow the animal to..(AU)

RESUMO

OBJECTIVE: To use the measurement of migration percentage (MP) to evaluate the long-term radiographic results of soft tissue surgery as the first treatment for hip displacement in spastic bilateral cerebral palsy. A secondary objective was to identify predictive factors of stability (i.e., less than 30% of MP in the long term), after surgical correction. METHODS: In this longitudinal cohort study, we reviewed the electronic medical records and radiographs of all consecutive patients with cerebral palsy operated for the correction of hip displacement between 1984 and 2013 in a referral orthopedic public hospital in Brazil. Patients were included if they had received, as the first surgical procedure, soft-tissue release. All surgeries were bilateral and symmetrical. We used the available radiographs to evaluate the migration percentage (MP), acetabular index (AI), pelvic obliquity (PO) angle, head-shaft angle (HSA), congruence and femoral head sphericity, and function using the GMFCS (Gross Motor Function Classification System). RESULTS: we included 93 patients, all operated before being 12 years old, with follow-up of 10 years in average, 73 (78%) of them with good results (MP < 30%). We found association between preoperative MP ≤ 40%, AI ≤ 25°, and postoperative symmetry with good results, with a cut-off value of 38% of MP and 27° of acetabular index being predictive. DISCUSSION: The role of soft tissue releases remains controversial owing to small sample sizes, heterogeneity, variety range of ages, definitions used for outcome, and lack of statistical quality. Our results were better in combined tenotomies, in diparetic patients aged more than six years, and in patients with lower initial values of MP and AI. Radiographic variables had good correlation with each other and association with results, with cut-off values for MP and AI PRE.

RESUMO

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.

RESUMO

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.(AU)

RESUMO

Flexural deformity in growing animals is a condition in which a joint is kept in a flexed or abnormally extended position. In foals, it is characterised mainly by deviation of the limbs. As such, the aim is to report a case of flexural deformity in a pelvic limb of Quarter Horse. The animal was treated at the Jerônimo Dix-Huit Rosado Maia Veterinary Hospital (HOVET-UFERSA): a female, with dappled coat, approximately two years of age, presenting with interphalangeal flexural deformity of the left pelvic limb. In the anamnesis, the owner reported that the animal had shown the deformity from six months of age, and on physical examination, presented grade IV lameness of the left pelvic limb, excessive wear of the toe, with the limb offering no support. Upon palpation, contracture of the superficial and deep digital flexor tendons was identified. Surgical treatment was therefore chosen, including tenotomy of the deep digital flexor tendon together with desmotomy of the lower check ligament. Medicinal therapy based on antibiotics and an anti-inflammatory was carried out, in addition to corrective trimming of the hoof and a horseshoe with toe extension; cleaning and changing the dressing was performed every 48 hours, and active physical therapy was given through a daily 15-minute walk. After 15 days hospitalisation, the animal was discharged, showing considerable improvement in it

A deformidade flexuralé uma condição de animais em crescimento, na qual uma articulação é mantida em posição flexionada ou estendida anormalmente. Em potros, caracteriza-se principalmente pelo desvio dos membros. Desta forma, objetiva-se relatar um caso de deformidade flexuralem membro pélvico de equino Quarto de Milha. Foi atendido no Hospital Veterinário Jerônimo Dix-Huit Rosado Maia (HOVET-UFERSA), umafêmea, da raça Quarto de Milha, pelagem tordilha, com aproximadamente dois anos de idade, apresentando deformidade flexuralinterfalangeana em membro pélvico esquerdo. Na anamnese, o proprietário relatou que o animal apresentava encastelamento do membro desde os 6 meses de idade. Ao exame físico, apresentou claudicação grau IV no membro pélvico esquerdo, desgaste excessivo de pinça, e sem apoio do membro. À palpação foi identificada contratura dos tendões flexores digitais superficial e profundo. Desta forma, optou-se pelo tratamento cirúrgico de tenotomia do tendão flexor digital

RESUMO

Flexural deformity in growing animals is a condition in which a joint is kept in a flexed or abnormally extended position. In foals, it is characterised mainly by deviation of the limbs. As such, the aim is to report a case of flexural deformity in a pelvic limb of Quarter Horse. The animal was treated at the Jerônimo Dix-Huit Rosado Maia Veterinary Hospital (HOVET-UFERSA): a female, with dappled coat, approximately two years of age, presenting with interphalangeal flexural deformity of the left pelvic limb. In the anamnesis, the owner reported that the animal had shown the deformity from six months of age, and on physical examination, presented grade IV lameness of the left pelvic limb, excessive wear of the toe, with the limb offering no support. Upon palpation, contracture of the superficial and deep digital flexor tendons was identified. Surgical treatment was therefore chosen, including tenotomy of the deep digital flexor tendon together with desmotomy of the lower check ligament. Medicinal therapy based on antibiotics and an anti-inflammatory was carried out, in addition to corrective trimming of the hoof and a horseshoe with toe extension; cleaning and changing the dressing was performed every 48 hours, and active physical therapy was given through a daily 15-minute walk. After 15 days hospitalisation, the animal was discharged, showing considerable improvement in it

A deformidade flexuralé uma condição de animais em crescimento, na qual uma articulação é mantida em posição flexionada ou estendida anormalmente. Em potros, caracteriza-se principalmente pelo desvio dos membros. Desta forma, objetiva-se relatar um caso de deformidade flexuralem membro pélvico de equino Quarto de Milha. Foi atendido no Hospital Veterinário Jerônimo Dix-Huit Rosado Maia (HOVET-UFERSA), umafêmea, da raça Quarto de Milha, pelagem tordilha, com aproximadamente dois anos de idade, apresentando deformidade flexuralinterfalangeana em membro pélvico esquerdo. Na anamnese, o proprietário relatou que o animal apresentava encastelamento do membro desde os 6 meses de idade. Ao exame físico, apresentou claudicação grau IV no membro pélvico esquerdo, desgaste excessivo de pinça, e sem apoio do membro. À palpação foi identificada contratura dos tendões flexores digitais superficial e profundo. Desta forma, optou-se pelo tratamento cirúrgico de tenotomia do tendão flexor digital(AU)

RESUMO

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.

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.
