RESUMEN

INTRODUCTION AND IMPORTANCE: Repairing massive rotator cuff tears (MRCTs) can often be technically challenging due to tendon retraction, bursal fibrosis, and muscular fatty infiltration that usually occurs, often resulting in poor outcomes and an unpredictable prognosis. Although some other surgical management options have been reported, there is a lack of literature supporting tendon transfers in the presence of combined anterior and posterior-superior irreparable rotator cuff tears. We describe a case where a combined transfer of the latissimus dorsi and lower trapezius tendons was employed to treat an MRCT affecting the anterior and posterior superior portions of the rotator cuff. CASE PRESENTATION: A 64-year-old male presented significant pain and limited range of motion in the right shoulder following a traumatic anterior shoulder dislocation seven months prior. MRI showed retracted tears (> 5 cm) of the supraspinatus, infraspinatus, and subscapularis tendons with significant fatty infiltration (Goutallier IV). The patient underwent an open transfer of the lower trapezius tendon to the greater tuberosity and the latissimus dorsi to the lesser tuberosity. At the final follow-up, 2.5 years postoperatively, the patient exhibited a painless functional range of motion and could resume daily activities. CLINICAL DISCUSSION: Although there are alternative surgical options available, the positive outcomes observed in the presented case may be attributed to the restoration of rotational strength and the re-establishment of force coupling across the shoulder. CONCLUSION: This report describes the successful implementation of a surgical treatment option for managing MRCT affecting the anterior and posterior superior portions of the rotator cuff.

RESUMEN

Background: Clavicle fractures are among the most common upper limb fractures in adults, with the midshaft region being the most frequently affected site. Minimally invasive plate osteosynthesis (MIPO) has emerged as an alternative to the traditional open reduction and internal fixation (ORIF) technique, offering potential advantages. The purpose of this study was to conduct a systematic review to explore the results of this technique in the existing literature, with emphasis on the occurrence of surgical complications and functional outcomes and also to provide a comprehensive comparison of MIPO and ORIF in the management of midshaft clavicle fractures. Methods: We conducted a systematic review to evaluate the complication incidence and clinical outcomes of MIPO for midshaft clavicle fractures. We searched PubMed/Medical Literature Analysis and Retrieval System Online (MEDLINE), Scopus, the Cochrane Database of Controlled Trials, and the Cochrane Database of Systematic Reviews databases without language or date restrictions. Studies focusing on midshaft clavicle fractures treated with MIPO were included, while other clavicle fractures and nonclinical studies were excluded. The risk of bias was assessed using the Methodological Index for Nonrandomized Studies criteria and the Risk of Bias Tool 2 Cochrane tool. Data synthesis included qualitative analysis, and if applicable, quantitative analysis and meta-analysis. Adherence to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines ensured reporting quality. Results: A total of 107 studies were initially identified, after applying inclusion and exclusion criteria, 22 studies were included for data extraction. These studies involved the evaluation of 714 clavicles treated with the MIPO technique. Of the 714 MIPO cases, 11 cases of implant failure, 5 nonunions, 2 infections, and 28 cases with neurological impairment were observed. Quantitative analysis comparing MIPO with ORIF revealed that MIPO had significantly shorter surgery time (mean difference -12.95, 95% confidence interval [-25.27 to -0.63], P = .04) and lower occurrence of numbness (odds ratio 0.29, 95% CI [0.15-0.56], P = .0002) compared to ORIF. Time to bone union, functional outcomes, and other complications were similar between MIPO and ORIF at the final follow-up. An overall moderate risk of bias was found across the studies. Conclusion: The MIPO technique yields good and comparable results to ORIF for midshaft clavicle fractures. Additionally, the MIPO technique may offer advantages such as reduced surgical time and lower chances of neurological impairment.

RESUMEN

BACKGROUND: Clavicle fractures account for approximately 5% of all fractures in adults and 75% of clavicle fractures occur in the midshaft. Shortening greater than two centimeters is an indicative of surgical treatment. Radiographic exams are often used to diagnose and evaluate clavicle fractures but computed tomography (CT) scan is currently considered the best method to assess these deformities and shortening. GOAL: 1- To investigate whether different methods of performing the radiographic exam interfere on the measurement of the fractured clavicle length. 2- Compare the clavicle length measurements obtained by the different radiographic exam methods with the CT scan measurements, used as a reference. MATERIALS AND METHODS: Twenty-five patients with acute (< 3 weeks) midshaft clavicle fracture were evaluated. Patients underwent six radiographic images: PA Thorax (standing and lying), AP Thorax (standing and lying) and at 10° cephalic tilt (standing and lying), and the computed tomography was used as reference. RESULTS: The mean length (cm) obtained were: 14,930 on CT scan, 14,860 on PA Thorax Standing, 14,955 on PA Thorax Lying, 14,896 on AP Thorax Standing, 14,960 AP Thorax Lying, 15,098 on 10° cephalic tilt Standing and 15,001 on 10° cephalic tilt Lying, (p > 0,05). CONCLUSION: 1- There is no significant statistical difference in the clavicle fracture length measurement among the variety of radiographic exam performances. 2- The method that comes closest to computed tomography results is the PA thorax incidence, with the patient in the lying position.

RESUMEN

OBJECTIVE: To evaluate the functional result of arthroscopic treatment in anterosuperior rotator cuff tears. METHODS: Fifty-six patients submitted to arthroscopic repair of anterosuperior rotator cuff tears were evaluated. The follow-up time was five year and five months. All the tears were diagnosed by detailed physical and imaging examination. Statistical analysis was used to compare the preoperative and postoperative results of range of motion and the UCLA score, with Wilcoxon signed-rank test, 5% significance level (p≤0.05), the relationship between the subscapularis tear and postoperative results using the Mann-Whitney test, and between the pain length and the UCLA scale using Spearman's correlation. RESULTS: A statistically significant improvement (p<0.001) was found, comparing the range of motion and the UCLA preoperatively and postoperatively. 39% of the cases were classified as excellent, 33.9% as good, 23.7% as regular and 3.4% as bad results. A statistically significant relationship was found between the subscapularis tear type and the functional state, the pain length and the postoperative UCLA scale. Five complications, four reruptures and one adhesive capsulitis were found. CONCLUSIONS: The arthroscopic treatment for anterosuperior tears presented satisfactory results, with 8.5% of complications. Level of Evidence IV, Case series.

RESUMEN

OBJECTIVE: To evaluate the evolution of injuries of the supraspinatus muscle by immunohistochemistry (IHC) and anatomopathological analysis in animal model (Wistar rats). METHODS: Twenty-five Wistar rats were submitted to complete injury of the supraspinatus tendon, then subsequently sacrificed in groups of five animals at the following periods: immediately after the injury, 24h after the injury, 48h after, 30 days after and three months after the injury. All groups underwent histological and IHC analysis. RESULTS: Regarding vascular proliferation and inflammatory infiltrate, we found a statistically significant difference between groups 1(control group) and 2 (24h after injury). IHC analysis showed that expression of vascular endothelial growth factor (VEGF) showed a statistically significant difference between groups 1 and 2, and collagen type 1 (Col-1) evaluation presented a statistically significant difference between groups 1 and 4. CONCLUSION: We observed changes in the extracellular matrix components compatible with remodeling and healing. Remodeling is more intense 24h after injury. However, VEGF and Col-1 are substantially increased at 24h and 30 days after the injury, respectively. Level of Evidence I, Experimental Study.

RESUMEN

OBJECTIVE: To determine the distance between the axillary nerve and the antero-lateral (AL) edge of the acromion, its anatomical variability and relationship to humeral length and body height. METHODS: Twenty-two shoulders were dissected. The anterosuperior (AS) approach was used; the deltoid was detached from the acromion and the distance between the AL portion and the axillary nerve was measured and submitted to statistical analysis. RESULTS: The distance varied from 4.3 to 6.4 cm (average 5.32 ± 0.60 cm). The axillary nerve distance increased as the humeral size (p<0.05) and the height of each cadaver increased. However, the correlation with the specimens height was not significant (p=0.24). CONCLUSIONS: The distance between the acromion and the axillary nerve on the AS approach was 5.32 ± 0.60 cm in both shoulders, and increasing the humeral length there is also an increase in the axillary nerve distance. Level of Evidence IV, Case Series - Anatomic Study.

RESUMEN

OBJECTIVES: To assess the outcomes of the arthroscopic margin convergence of the posterior cuff to the biceps tendon. METHODS: From October 2003 to December 2007, 20 patients with massive rotator cuff tear which include the rotator interval were treated with arthroscopic margin convergence of the posterior cuff to biceps tendon. Sixteen patients were female and four were male. The mean age was 58.95 years old. The dominant side was affected in 16 cases (80%). The outcomes were analysed according to the UCLA Score with a minimum follow-up period of two years. RESULTS: The UCLA score improved, on average, 14 points (p < 0.001). Six patients had excellent results; nine good; three fair and two poor results. The mean improvement of forward flexion was 33º (p < 0.001), 3º of external rotation (p < 0.396) and two vertebral levels for internal rotation (p < 0.025). CONCLUSION: The arthroscopic margin convergence of the posterior cuff to the biceps tendon leads to satisfactory results. .

RESUMEN

OBJECTIVE: To determine if it is possible to measure glenoid bone loss by using the Bernageau view and to compare it to a 3D CT scan. MATERIALS AND METHODS: Fifty healthy subjects with a mean age of 34 ± 8 years old and 31 (62 %) male were submitted to the Bernageau view X-ray of both shoulders. Three blinded evaluators measured the distance between the posterior and anterior glenoid rim. Ten patients with multiple episodes of unilateral traumatic anterior shoulder dislocation with a mean age of 34 ± 9.1 years old and 90 % male were submitted to the same X-ray technique to determine the percentage of glenoid bone loss. They were also submitted to a bilateral 3D CT scan to be compared to the radiographs. RESULTS: In the 50 asymptomatic subjects, the AP distance was 24.48 mm ± 3.32 mm in the left shoulder and 24.82 mm ± 3.16 mm in the right shoulder. Comparing the X-ray study and the 3D CT scan of the ten patients with multiple episodes, there was no significant statistical difference of the AP normal distance in both methods (p = 0.646), the AP erosion distance (p = 0.386), as well as the percentage of bone loss (p = 0.513). Moreover, the differences between the percentages of bone loss in the X-ray, compared with the 3D CT scan were, on average 2.28 % (range 0 to 6.05 %). CONCLUSIONS: The Bernageau radiographic view is an accurate and reproducible technique for measuring the presence of glenoid erosion, with similar results when compared to the 3D CT scan.

RESUMEN

OBJETIVO: Avaliar o resultado da cirurgia de Latarjet para pacientes com luxação recidivante anterior do ombro com perda óssea maior que 25 por cento da cavidade glenoidal. MÉTODO: Avaliamos 26 pacientes submetidos à cirurgia de Latarjet. O tempo médio de seguimento foi de 38 meses e a média etária, de 28 anos. Os pacientes foram avaliados quanto à amplitude de movimento e pelas escalas de Rowe e UCLA, no período pré-operatório como no período pós-operatório, radiografias do ombro para avaliar a presença de artrose, posição e consolidação do enxerto e posicionamento dos parafusos. A análise estatística foi utilizada para avaliar se haveria relação entre o número de episódios de luxação, presença de artrose, correlação entre artrose e limitação da rotação lateral. Comparar a diferença entre o arco de movimento do lado operado com o não acometido e avaliação funcional pré e pós-operatória das escalas de UCLA e Rowe. RESULTADOS: A elevação e rotação lateral foram estatisticamente inferiores do lado operado. A escala de UCLA e a de Rowe mostrou uma melhora estatisticamente significante dos resultados clínico-funcionais (P < 0,001 em ambas). Houve relação entre o número de episódios de luxação e a presença de artrose, mas não pudemos confirmar que os casos mais graves de artrose foram os que mais luxaram pela amostra ser pequena. CONCLUSÃO: A cirurgia de Latarjet é um método eficaz para casos graves de erosão da borda da cavidade glenoidal.

OBJECTIVE: Evaluate the results from the Latarjet procedure in patients with anterior recurrent dislocation of the shoulder who present bone loss of the glenoid cavity greater than 25 percent. METHODS: Twenty six male patients underwent the Latarjet procedure, The bone loss was evaluated by means of radiography using the Bernageau view and by means of CAT scan. The patients were evaluated with regard to range of motion, using the Rowe and UCLA scales, before and after the operation, and by radiographs to assess the presence of arthrosis, position and consolidation of the graft and positioning of the screws. Statistical analysis was used to assess whether there was any relationship between the number of episodes of dislocation and the presence of arthrosis, , and any relationship between arthrosis and limitations on lateral rotation. Differences in range of motion between the operated and unaffected sides and in the UCLA and Rowe scale. RESULTS: The means for elevation and lateral rotation were statistically poorer on the operated side. The UCLA and Rowe scale showed that there was a statistically significant improvement in the clinical-functional results (P < 0.001 for both). There was a relationship between the number of episodes of dislocation and the presence of arthrosis, We also did not observe any correlation between limitations on lateral rotation and arthrosis. CONCLUSION: The Latarjet procedure is an efficient method for cases of severe erosion of the glenoid margin.

RESUMEN

Objetivo: Avaliar a prevalência de alterações radiográficas no terço proximal do úmero de 21 jovens arremessadores de beisebol e correlacioná-las aos achados clínicos. Desenho do estudo: Série de casos. Local: Estudo realizado pelo Grupo de Cirurgia do Ombro e Cotovelo da Disciplina do Estudo das Afecções Ortopédicas da Faculdade de Medicina do ABC. Santo André, São Paulo, Brasil. Instituição terciária. Pacientes: Foram estudados 21 adolescentes do sexo masculino arremessadores de beisebol, com idade média de 14,5 anos da Seleção Brasileira de Beisebol. Intervenção: Os pacientes foram submetidos a avaliações radiográficas dos ombros. Resultados: Dos atletas, 14 (66%) apresentaram alterações radiográficas na placa de crescimento do terço proximal do úmero. Destes, em nove atletas (64%) nos quais os observadores encontraram alterações radiográficas não apresentavam queixa de dor. Também se observou que em apenas 11 pacientes havia correlação entre os achados clínicos e radiográficos. Conclusão: Concluímos que alterações radiográficas na placa de crescimento do terço proximal de úmero foram encontradas em 66% dos atletas avaliados e não foi encontrada correlação com a avaliação clínica. A presença de alargamento da placa de crescimento do terço proximal do úmero no ombro dominante de jovens arremessadores de beisebol pode acontecer em atletas assintomáticos. Provavelmente, esse alargamento representará, no futuro, uma maior retroversão do ombro dominante do arremessador.

RESUMEN

OBJETIVO: Avaliar a eficácia do bloqueio do nervo supraescapular associado à infusão de anestésico no espaço subacromial e compará-lo ao bloqueio interescalênico. MÉTODO: Avaliamos, prospectivamente e comparativamente, a eficácia dos métodos anestésicos em 45 pacientes com lesões pequenas ou médias isoladas do tendão do supraespinhal submetidos ao reparo artroscópico. Os pacientes foram divididos aleatoriamente em três grupos de 15, cada um com uma diferente combinação de métodos anestésicos. A eficácia da analgesia pós-operatória foi mensurada utilizando-se a escala visual da dor e consumo de drogas analgésicas, anti-inflamatórias e opioides. O consumo de anestésicos inalatórios durante a cirurgia também foi comparado entre os grupos. RESULTADOS: A análise estatística não encontrou diferenças estatisticamente significativas entre os grupos com relação ao consumo de anestésico durante a cirurgia e a eficácia analgésica pós-operatória nas primeiras 48 horas. CONCLUSÃO: O bloqueio do nervo supraescapular associado à infusão de anestésico no espaço subacromial é uma excelente alternativa ao bloqueio interescalênico, particularmente em hospitais que não dispõem do estimulador elétrico de nervo.

OBJETIVE: To evaluate the efficacy of suprascapular nerve block in combination with the infusion of anesthetic into the subacromial space compared to an interscalene block. METHODS: Forty-five patients with small or medium isolated supraspinatus tendon lesions who underwent arthroscopic repair were prospectively evaluated and randomly assigned to three groups of 15, each with a different combination of anesthetic methods. The efficacy of post-surgical analgesia was measured using the visual analogue scale for pain, and analgesic, anti-inflammatory, and opioid drug consumption. Inhalation anesthetic consumption during surgery was compared among the groups. RESULTS: Statistical analysis found no significant differences among the groups regarding anesthetic consumption during surgery or postoperative analgesic efficacy during the first 48 hours. CONCLUSION: Suprascapular nerve block with infusion anesthetic into the subacromial space is an excellent alternative to interscalene block, particularly in hospitals where a nerve stimulator device is unavailable.
