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.

Fascia lata autograft bridging combined with long head of biceps tendon transposition for irreparable massive rotator cuff tear / 中华骨科杂志

Objective:To investigate the early clinical effect of fascia lata autograft bridging combined with the long head of biceps tendon transposition for treatment of irreparable massive rotator cuff tear.Methods:All of 31 cases of massive irreparable rotator cuff tear treated in our hospital from March 2016 to March 2020 were analyzed retrospectively. Among them, 17 cases (10 males, 7 females) were repaired with fascia lata autograft bridging under arthroscopy (patch group), the average age was 61.47±6.63 (ranging from 51 to 72) and 14 cases (4 males, 10 females) were repaired with fascia lata autograft bridging combined with the long head of biceps tendon transposition (combined group), the average age was 62.57±6.11 (ranging from 53 to 71). The operation time, intraoperative blood loss, postoperative complications, visual analogue scale (VAS) of pain before operation, at 1 week and 12 months after operation, Constant-Murley score of shoulder joint and American Association of shoulder and elbow Surgeons (ASES) score before operation, at 6 months and 12 months after operation were compared between the two groups. The outcome of rotator cuff healing was evaluated by MRI 1 year after operation.Results:All patients were followed up for 12-27 months (mean 18.33 ±6.8 months). There was no perioperative complication, and there was no significant difference in operation time between the two groups ( P>0.05) . The VAS score in the patch group was significantly higher than the combined group 1 week after operation ( t=2.09, P=0.048) , and there was no significant difference in VAS score 12 months after operation between the two groups. Constant-Murley score and ASES score in the combined group were significantly higher than the patch group at 6 months after operation ( t=5.23, P<0.001; t=4.45, P<0.001) , and there was no significant difference in Constant score and ASES score between the two groups at 12 months after operation. Constant score and ASES score in the two groups were significantly higher than those before operation. One year after operation, the MRI of the affected shoulder showed that the incidence of autograft patch thinning (Sugaya grade III) was 52.94%, the autograft patch structure failure rate (Sugaya grade IV and V) was 17.65% in the patch group, the autograft patch thinning rate (Sugaya grade III) was 35.71%, and the structural failure rate (Sugaya grade IV and V) was 7.14% in the combined group. The difference was statistically significant (χ 2=7.12, P=0.028) . Conclusion:Fascia lata autograft patch bridging combined with long head of biceps tendon transposition technique for treatment of irreparable massive rotator cuff tear has less pain 1 week after operation and better recovery of shoulder function half a year after operation. MRI showed better patch healing 1 year after operation.

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.

The “POPEYE SIGN” – A Classical but Rare Case

@#Isolated biceps tendon rupture is rarely reported at primary care level. A 78-year-old man presented with deformity over his right mid arm for one week, following a low impact trauma over his right shoulder six weeks prior. Physical examination revealed the classical sign of rupture of the long head of biceps tendon (LHBT) which showed bulging of his right biceps muscle, resembling the famous cartoon character, “Popeye The Sailorman”. Diagnosis of rupture of LHBT was made in the primary care clinic without the need of imaging modality based on the identification of the “Popeye Sign”. Diagnosis and condition have been explained well to patient and caretaker without the need for inappropriate investigation and procedures. Conservative treatment approach was opted. His condition was stable without new active complaints on subsequent follow up. This case proved that stable ruptures of LHBT are still possible to be managed at primary care level.

A Case Series of Symptomatic Distal Biceps Tendinopathy

BACKGROUND: The study of conservative and surgical treatment of distal biceps tendinopathy and associated biceps tendon partial rupture. METHODS: Twenty-one cases with distal biceps tendonitis and partial ruptures were studied who visited Pohang Semyeong Christianity Hospital from June 2010 to August 2017. The mean age was 57.1 years (39–69 years), 14 males and 7 females. The mean duration of symptom at the time of first visit was 4.9 months (0.2–14 months). Ultrasonography and magnetic resonance imaging were performed for patients with severe symptoms. According to the severity of the symptoms, splint immobilization, oral nonsteroidal anti-inflammatory drugs, and ultrasound-guided steroid injection were performed. Surgical treatment was performed if the patient did not respond to conservative treatment for 3 to 6 months or longer. RESULTS: There were 9 cases of partial rupture of the distal biceps tendon associated with distal biceps tendinopathy on imaging studies. Conservative treatment showed symptomatic improvement in 16 of 21 cases. In 4 cases with a relatively mild symptom, anti-inflammatory analgesics and intermittent splinting showed good result. In 12 cases, symptoms improved after ultrasonography-guided steroid injection. Surgical treatment was performed on 5 cases that did not respond to conservative treatment. CONCLUSIONS: Conservative treatment of distal biceps tendinopathy may promise good results. However, in case of partial tear of the distal biceps tendon and refractory to conservative treatment, surgical treatment may be needed.

Osteochondroma of the Distal Clavicle: A Rare Cause of Impingement and Biceps Tear of the Shoulder

Hereditary multiple exostosis (HME) is an autosomal dominant disorder manifested by the presence of multiple osteochondromas. Although the lesions are benign in nature, exostoses are often associated with characteristic progressive skeletal deformity and displaying clinical symptoms such as mechanical irritation or impingement. We present the successful arthroscopic resection in a 24-year-old HME male with impingement syndrome and long head tendon tear of the biceps caused by osteochondroma arising from the distal clavicle.

Is There a Clinically Important Superior Labrum Anterior to Posterior (SLAP) Lesion? / 대한정형외과학회잡지

Superior labrum anterior to posterior (SLAP) lesion is a tear of the superior labrum, which starts posteriorly and extends anteriorly to include the anchor of the biceps tendon to the superior labrum. Symptoms of SLAP tear may include pain or instability. Recently, with the development of arthroscopy, the diagnosis and treatment of SLAP lesion have been made a lot. However, the diagnosis of clinically relevant SLAP tears remains challenging because of the lack of specific examination findings and the frequency of concomitant shoulder lesion. And there is still controversy regarding the treatment. Accordingly, proper treatment is important through accurate evaluation of whether or not it is a clinically important SLAP lesion.

Clinical Application of High-frequency Ultrasound in Long Head of Biceps Tendon and Bicipital Groove in Patients with Complex Regional Pain Syndrome / 中国康复理论与实践

@#Objective To evaluate the application of high-frequency ultrasound in the detection of long head of biceps tendon and bicipi-tal groove in patients with hemiplegia-secondary complex regional pain syndrome. Methods From February, 2013 to October, 2015, 55 pa-tients with hemiplegia-secondary complex regional pain syndrome were enrolled. The thickness and cross-sectional area of long head of bi-ceps tendon, and the width and depth of bicipital groove in healthy and affected sides were measured and analyzed comparatively with the clinical stages. Results The thickness and cross-sectional area of long head of biceps tendon became thin and reduced significantly, and the width and depth of bicipital groove became narrow and shallow in the affected sides at stages Ⅱ and Ⅲ (t>2.055, P<0.05);while no signifi-cant difference was found between two sides at stage I (P>0.05). Conclusion High-frequency ultrasound could clearly display the long head of biceps tendon and bicipital groove, and detect the morphological change, that can be helpful for rehabilitation.

Objective To investigate MR and US diagnotic value of long head of the biceps tendon injury.Methods A total of 80 patients with suspected injury of long head of the biceps tendon underwent arthroscopy surgery.All patients had MR and US examination preoperatively.The preoperative results were compared with the findings during the arthroscopy in order to assess the effectiveness of two methods.Results Among 80 patients, there were completely torn in 19 cases, partly torn in 45 cases, biceps tendon tenosynovitis in 10 cases, biceps tendon slippage in 6 cases.The accuracy of MR and US in the diagnosis of completely torn, partly torn, biceps tendon tenosynovitis, biceps tendon slippage were 98.7%,92.5%,97.5%,100% and 96.2%,85.0%,96.3%,98.7% respectively.There was no statistic difference between MR and US in diagnosing completely torn,biceps tendon tenosynovitis and biceps tendon slippage(P>0.05),but the accuracy of MR in diagnosing partly torn was higer than US(P<0.05).Conclusion MR determination of biceps tendon partial tear is of obvious advantages.US examination can be used as a routine method for the investigation of patients with suspected biceps tendon injury.

Zona de seguridad para tornillo de bloqueo cefálico posterior-anterior durante enclavijado endomedular retrógrado del húmero: estudio ex vivo en muestras óseas / Safe zone for anterior-posterior cranial blocking screw during retrograde intramedullary nailing of the humerus: ex-vivo study in bone specimens

OBJETIVO: Definir una zona segura, usando como referencia la línea intercondílea anterior (LCA) del codo para realizar los bloqueos anteroposteriores durante el enclavijado endomedular retrógrado humeral (CEMR). MÉTODOS: Estudio experimental ex-vivo. Trece húmeros humanos fueron analizados. Se tomaron fotografías registrando la porción distal de los húmeros paralelos a la LCA, elevando el húmero distal 10cm. Tres evaluadores independientes realizaron las siguientes mediciones: ángulo del surco bicipital (SB) a la altura del cuello quirúrgico humeral (S, formado por las paredes medial y lateral del SB; zona de peligro) y el ángulo complementario lateral (formado por el límite lateral de la tróclea y la pared lateral del SB a la altura del cuello quirúrgico humeral; zona segura). RESULTADOS: Valor promedio de S: 3,1±0,5° (3,3-4), coeficiente de correlación intraclase: 0,057 (p=0,057). Valor promedio del ángulo complementario lateral: 87,5±3,3° (81,3-92,5), coeficiente de correlación intraclase: 0,304 (p=0,217). Considerando 3 desviaciones estándar del promedio de los ángulos medidos (para aumentar los parámetros de seguridad) la zona segura se enmarcó entre los 0° y los 80° con relación a la LCA. CONCLUSIÓN: En este estudio la zona de seguridad del bloqueo cefálico anteroposterior para evitar el daño del tendón bicipital durante el enclavijado endomedular retrógrado humeral se localizó entre los 0° y 80° con relación a la LCA.

OBJECTIVE: To define a safe zone, using the anterior intercondylar line (AIL) of the elbow as a reference to perform anterior-posterior (AP) cranial blocks during retrograde intramedullary humeral nailing (RIHN). METHODS: An ex-vivo experimental study was performed by analysing 13 human humeri. Photographs were taken, recording the distal portion of the humeri parallel to the AIL, elevating the distal humerus 10cm. Three independent evaluators made the following measurements: Bicipital groove (BG) angle at the level of the surgical neck of the humerus (S, formed by the medial and lateral walls of the BG; danger zone) and the Lateral Complementary Angle (LCA, formed by t5he lateral trochlear limit and the lateral wall of the BG at the level of the surgical neck of the humerus; safe zone). RESULTS: The mean value of S: 3.1±0.5° (3.3-4), intraclass correlation coefficient (ICC): 0.057 (P=.057). The mean value of the AIL: 87.5±3.3° (81.3-92.5), ICC: 0.304 (P=.217). Using 3 standard deviations from the mean of the angles measured (in order to increase the safety parameters), the safety zone is located between 0° and 80° in relation to the AIL. CONCLUSION: In this study, the safety zone of the AP cranial block, in order to avoid damage to bicipital tendon during RIHN, is situated between 0° and 80° in relation to the AIL.

The Correlation between Modified Ashworth Scale and Biceps T-reflex and Inter-rater and Intra-rater Reliability of Biceps T-reflex

OBJECTIVE: To establish a correlation between the modified Ashworth scale (MAS) and amplitude and latency of T-reflex and to demonstrate inter-rater and intra-rater reliability of the T-reflex of the biceps muscle for assessing spasticity after stroke. METHOD: A total of 21 patients with hemiplegia and spasticity after ischemic stroke were enrolled for this study. The spasticity of biceps muscle was evaluated by an occupational therapist using the MAS. The mean value of manual muscle test of biceps muscles was 2.3+/-0.79. Latency and amplitude of T-reflex were recorded from biceps muscles by two physicians. The onset latency and peak to peak amplitude of the mean of 5 big T-reflex were measured. The examinations were carried out by two physicians at the same time to evaluate the inter-rater reliability. Further, one of the physicians performed the examination again after one week to evaluate the intra-rater reliability. The correlations between MAS and T-reflex, and the intra- and inter-rater reliability of biceps T-reflex were established by calculating the Spearman correlation coefficients and the intra-class correlation coefficients (ICCs). RESULTS: Amplitude of the biceps T-reflex increased with increasing level of MAS (rs=0.464 and 0.573, respectively, p<0.01). ICCs of latency and amplitude of biceps T-reflex were 0.914 and 0.822. The Spearman correlation coefficients of latency and amplitude of biceps T-reflex were 0.937 and 0.635, respectively (p<0.01). CONCLUSION: Biceps T-reflex demonstrates a good quantitative measurement and correlation tool with MAS for spasticity, and also shows acceptable inter- and intra-rater reliability, which can be used for patients with spasticity after stroke.

Long Head of the Biceps Tendon Lesion Associated with Rotator Cuff Tear

PURPOSE: To evaluate pathologic patterns and outcomes of treatment of a biceps tendon lesion associated with a rotator cuff tear. MATERIALS AND METHODS: We reviewed 92 patients (i) who underwent surgery for a cuff tear, (ii) for whom the biceps lesion could be observed retrospectively, and (iii) had a minimum follow-up of 2 years. The pathology of biceps tendon was classified into 4 types: tenosynovitis, fraying or hypertrophy, tear, and instability. All but the 4 with massive cuff tears were repaired. The biceps lesions were treated with debridement in 30, tenotomy in 10, tenodesis in 8, and recentering in 4. UCLA scoring was used for clinical results. RESULTS: Seventy patients had a biceps lesion, 19 tenosynovitis, 22 fraying or hypertrophy, 21 a tear, and 8 instability. A biceps lesion was observed in 63% of cases of cuff tears below the medium size, and in 88% of cases with cuff tears above the large size. UCLA scores according to the pathology of the biceps lesion were 29.6 in the absence of a biceps lesion, and 28.3 in its presence. UCLA scores in patients with tenotomy or tenodesis for associated biceps tendon lesions were 28.2. CONCLUSION: There is a greater incidence and severity of a biceps lesion with a larger cuff tear. Therefore, the cause of a biceps lesion might be related to the cause of the cuff tear. Among the several options of treatment for biceps lesion, tenotomy or tenodesis may be particularly effective in providing pain relief.

Short-Term Results of Subpectoral Tenodesis of the Proximal Biceps Tendon Using by Interference Screw

PURPOSE: Our purpose was to retrospectively analyze clinical results of subpectoral tenodesis of the proximal biceps tendon using an interference screw. MATERIALS AND METHODS: We reviewed 23 cases of patients receiving tenodesis of the proximal biceps tendon between January 2008 and January 2009 for whom we had follow-up data for at least 1 year. Twenty-three cases were operated on using subpectoral tenodesis; 16 of these cases had a rotator cuff tear. The results were judged using a visual analog scale (VAS), ASES, tenderness on the biceps groove, fixation failure and the degree of deformity (BAD). RESULTS: VAS and ASES scores were significantly improved in all patients by the time of the final observation. There were no significant complications or fixation failures. The patients without a tear of the rotator cuff had a better result than patients with a tear of the rotator cuff, but the difference between the two groups was not significant (p>0.05). CONCLUSION: In patients with pathology of the long head of the biceps brachii, benefits of subpectoral interference screw tenodesis include pain relief, maintenance of functional biceps, muscle strength, and cosmesis. Subpectoral biceps tenodesis using interference screw fixation appears to be a promising, reproducible, reliable technique for addressing anterior shoulder pain related to pathology of the long head of the biceps brachii.

Efficacy of Ultrasonogram for the Diagnosis of Biceps Tendon Pathology

PURPOSE: We wanted to assess the accuracy of ultrasound for detecting abnormality of the long head of the biceps tendon in patients with rotator cuff disorders. MATERIALS AND METHODS: Between January 2006 and March 2007, we reviewed the arthroscopic findings of biceps tendons in 67 patients with rotator cuff disorder and who underwent ultrasonography pre-operatively. The patients' average age was 58 years and there were 41 males and 26 females. The statuses of the biceps tendons were described as 'normal', 'dislocation', 'subluxation', 'partial or complete tears', and 'tendinopathy'. We investigated the correspondence between the arthroscopic and ultrasonographic findings. RESULTS: On ultrasonography, the biceps tendons were 'normal' in 37 patients and 'abnormal' in 30 patients. On arthroscopy, 5 biceps tendons turned out to have partial tears, which were 'normal' on ultrasonography. On the other hand, 8 biceps tendons were 'normal' which were 'abnormal' on ultrasonography. Three dislocations and 4 complete tears of biceps tendons were identified on arthroscopy, and all of them were detected by ultrasonography. Of the 20 cases of 'tendinopathy' seen on ultrasonography, 15 patients had partial tears and the remaining 5 patients were normal on arthroscopy. CONCLUSION: Ultrasonography is accurate for detecting some biceps pathologies, such as dislocation or complete tear, but it is not accurate for the detection of partial tear.

Mid-term Results of Biceps Incorporating Suture Without Deteaching the Biceps Tendon from the Flenoid in the Large or Massive Cuff Tear

PURPOSE: The aim of this study is to analyze the clinical results of using the technique of rotator cuff repair without parting the biceps long head from the glenoid for large or massive tear of the rotator cuff. MATERIAL AND METHODS: Form January 2005 to January 2007, we performed the arthroscopic biceps repair with incorporating suture to the rotator cuff for 21 patients with large or massive rotator cuff tear. The mean follow up period was 23 months (range: 6-48months). The number of males and females was 9 and 13, respectively. The age distribution ranged from 47 to 73 years with a mean age of 60.3 years. We compared the preoperative score with the postoperative scores using the University of California Los Angeles (UCLA) score, the shoulder index of the American Shoulder and Elbow Surgeons (ASES) and a simple shoulder test (SST). RESULTS: The improvement in the VAS, ASES and the UCLA and SST scores was statistically significant at the final follow up (average follow-up 23 months) (p>0.05). Two of nine cases were found to have partial tear with continuity but seven cases were found to have complete tear according to the ultrasonography and MRI. CONCLUSION: The technique of rotator cuff repair without parting the biceps long head from the glenoid for large or massive tear of the rotator cuff is considered to be recommendable.

MRI Findings of Adhesive Capsulitis of Shoulder

OBJECTIVE: MRI findings of adhesive capsulitis (AC) have been rarely documented even though the disease is a rather common disorder. To find reliable MRI parameters, we studied MRI findings of the patients with arthrographically-proven AC. METHOD: Eighteen patients with AC (patient group) and eight subjects without AC (control group) were enrolled. Mean age of the former was 55.1 years and that of the latter was 41.4 years. Mean duration of the diseases in patient group was 5.9 months. Oblique coronal and axial MRI images of the shoulder were measured for the thickness of capsule and synovium around the axillary fold (TAF), volume of axillary recess (VAR), and volume of biceps tendon sheath (VBTS), which were compared in both groups using unpaired t-test. RESULTS: TAF was significantly increased in patient group (p<0.0001), and the thickened axillary fold greater than 5.1 mm was a useful MRI criterion for the diagnosis of AC with sensitivity of 93% and with specificity of 100%. VBTS was also significantly diminished in patient group (p<0.05), whereas there was no significant difference in VAR between two groups. CONCLUSION: TAF, especially greater than 5.1 mm, and decreased VBTS are useful MRI parameters for the diagnosis of AC of shoulder.
