Reprodutibilidade de três classificações de fraturas na região proximal do úmero

OBJECTIVE: To propose a new system for classifying proximal humeral neck fractures, and to evaluate intra- and interobserver agreement using the Neer system that is the most commonly used in the area and the Arbeit Gemeinschaft für Osteosynthesefragen system created by an European group, and a new classification system proposed by the authors of this study. METHODS: A total of 56 patients with proximal humeral fractures were selected, and submitted to digitized simple radiography in antero-posterior shoulder and scapular profile. Radiographs were analyzed by three observers at time one, and then three and six weeks later. The kappa coefficient modified by Fleiss was used for the analysis. RESULTS: The mean intra-observer Kappa agreement index (k=0.687) of the new classification, was higher than both the Neer classification (k=0.362) and the Arbeit Gemeinschaft für Osteosynthesefragen (k=0.46). The mean interobserver Kappa agreement index (0.446) of the new classification, also had better results than both the Neer classification (k=0.063) and the Arbeit Gemeinschaft für Osteosynthesefragen (k=0.028). CONCLUSION: the new classification considering bone compression had higher results for intra- and interobserver compared to the Neer system, and the Arbeit Gemeinschaft für Osteosynthesefragen system.OBJETIVO: Propor um novo sistema para classificação das fraturas que envolvem o colo do úmero e avaliar a concordância intra e interobservador do sistema de classificação de Neer (a mais utilizada em nosso meio), do sistema proposto pelo grupo europeu Arbeit Gemeinschaft für Osteosynthesefragen e de um novo sistema de classificação proposto pelos autores. MÉTODOS: Foram selecionados 56 pacientes com fraturas da região proximal do úmero, com radiografias simples digitalizadas nas incidências anteroposterior do ombro e perfil da escápula. Quatro observadores avaliaram as imagens radiográficas em três momentos diferentes, com intervalos de 3 semanas. Os dados foram analisados segundo o coeficiente de concordância kappa, modificado por Fleiss. RESULTADOS: O índice de concordância kappa intraobservador médio da nova classificação (k=0,687) foi superior ao da classificação de Neer (k=0,362) e da Arbeit Gemeinschaft für Osteosynthesefragen (k=0,46). O índice de concordância kappa interobservador da nova classificação (k=0,446) também apresentou um valor médio maior que o da classificação de Neer (k=0,063) e da Arbeit Gemeinschaft für Osteosynthesefragen (k=0,028). CONCLUSÃO: A nova classificação, que considera o conceito de compressão óssea, apresentou melhores resultados inter e intraobservador, em relação às classificações de Neer e Arbeit Gemeinschaft für Osteosynthesefragen.Hospital Israelita Albert EinsteinUniversidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

A tomografia computadorizada e sua reconstrução 3D aumentam a reprodutibilidade das classificações das fraturas da extremidade proximal do úmero?

OBJECTIVE:to determine whether 3D reconstruction images from computed tomography (CT) increase the inter and intraobserver agreement of the Neer and Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification systems.METHODS:radiographic images and tomographic images with 3D reconstruction were obtained in three shoulder positions and were analyzed on two occasions by four independent observers.RESULTS:the radiographic evaluation demonstrated that using CT improved the inter and intraobserver agreement of the Neer classification. This was not seen with the AO classification, in which CT was only shown to increase the interobserver agreement.CONCLUSION:use of 3D CT allows better evaluation of fractures with regard to their component parts and their displacements, but nevertheless the intraobserver agreement presented is less than ideal.OBJETIVO:determinar se as imagens da reconstrução 3D da tomografia computadorizada (TC) aumentam a concordância inter e intraobservador dos sistemas de classificação de Neer e Arbeitsgemeinschaft für Osteosynthesefragen (AO).MÉTODOS:foram obtidas imagens radiográficas em três posições do ombro e imagens tomográficas com reconstrução 3D, que foram analisadas em dois tempos por quatro observadores independentes.RESULTADOS:a avaliação radiográfica demonstrou que o uso da TC melhora a concordância intra e interobservadores para a classificação de Neer. O mesmo não foi observado na classificação AO, na qual a TC demonstrou aumento somente da concordância interobservadores.CONCLUSÃO:o uso de TC 3D permite uma melhor avaliação da fratura quanto às partes que a compõem e aos seus desvios, mas mesmo assim apresenta uma concordância intraobservadores menor do que a ideal.Universidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

Efetividade da injeção intrarticular de lidocaína na redução das luxações anteriores do ombro: ensaio clínico randomizado

CONTEXT AND OBJECTIVE: Shoulder dislocation is the most common dislocation among the large joints. The aim here was to compare the effectiveness of reduction of acute anterior shoulder dislocation with or without articular anesthesia. DESIGN AND SETTING: Prospective randomized trial conducted in Escola Paulista de Medicina, Universidade Federal de São Paulo (UNIFESP) (EPM-UNIFESP). METHODS: From March 2008 to December 2009, 42 patients with shoulder dislocation were recruited. Reductions using traction-countertraction for acute anterior shoulder dislocation with and without lidocaine articular anesthesia were compared. As the primary outcome, pain was assessed through application of a visual analogue scale before reduction, and one and five minutes after the reduction maneuver was performed. Complications were also assessed. RESULTS: Forty-two patients were included: 20 in the group without analgesia (control group) and 22 in the group that received intra-articular lidocaine injection. The group that received intra-articular lidocaine had a statistically greater decrease in pain over time than shown by the control group, both in the first minute (respectively: mean 2.1 (0 to 5.0), standard deviation, SD 1.3, versus mean 4.9 (2.0 to 7.0, SD 1.5; P < 0.001) and the fifth minute (respectively: mean 1.0; 0 to 3.0; SD = 1.0 versus mean 4.0; 1.0 to 6.0; SD = 1.4; P < 0.001). There was one failure in the control group. There were no other complications in either group. CONCLUSION: Reduction of anterior shoulder dislocation using intra-articular lidocaine injection is effective, since it is safe and diminishes the pain.

Functional outcomes of traumatic and non-traumatic rotator cuff tears after arthroscopic repair

AIM To compare the functional outcomes of traumatic and non-traumatic rotator cuff tears after arthroscopic repair. METHODS Eighty-seven patients with rotator cuff tears following arthroscopic treatment were divided into traumatic and non-traumatic tear groups. Postoperative muscle strength and outcomes using the modified University of California, Los Angeles score were evaluated. Sex, age, affected limb and dominant limb were correlated between groups. Muscle strength of the repaired and unaffected shoulders was compared. Rotator cuff injury size was measured. RESULTS Of the 87 patients who underwent rotator cuff repairs, 35 had traumatic tears and 52 had non-traumatic tears. In patients with non-traumatic tears, the average age was 59 years, 74.5% were female, 96.1% were righthand dominant and 92.3% had their dominant shoulder affected. Patients with traumatic tears were 59.5 years hand dominant and 88.5% had their dominant shoulder affected. No difference existed in the mean modified University of California, Los Angeles score between patients with traumatic tears (33.7) compared with those with non-traumatic tears (32.8). No strength differences were observed between groups: The strength difference between the non-affected and affected sides was 1.21 kg in the non-traumatic group and 1.39 kg in the traumatic group (P = 0.576), while the strength ratio between the non-affected/affected sides was 0.805 in the nontraumatic group and 0.729 in the traumatic group (P = 0.224). CONCLUSION The functional results of traumatic rotator cuff repairs are similar to non-traumatic tears. Both outcomes are satisfactory.Univ Fed São Paulo, Orthoped & Traumatol Dept, Shoulder & Elbow Surg Sector Hand & Upper Limb Su, BR-04038030 São Paulo, SP, BrazilShoulder Surg Sector Hosp Ortoped Belo Horizon, BR-30210300 Belo Horizonte, MG, BrazilUniv Fed São Paulo, Orthoped & Traumatol Dept, Shoulder & Elbow Surg Sector Hand & Upper Limb Su, BR-04038030 São Paulo, SP, BrazilWeb of Scienc

Result from surgical treatment on the terrible triad of the elbow

AbstractObjectiveTo evaluate the results from surgical treatment of the terrible triad of the elbow, with a minimum of six months of follow-up, taking elbow function into consideration.MethodsThe analyzed aspects of 20 patients, who underwent surgical treatment of the terrible triad of the elbow, were given as follows: Dash score (Disabilities of the Arm, Shoulder and Hand), Meps (Mayo Elbow Performance Score), pain according to VAS (visual analog scale), ROM (range of motion), patient satisfaction, degree of energy of the trauma, complications and radiographs.ResultsThe mean length of follow-up among the patients was 38 months. There were statistically significant relationships between the following set of parameters: trauma mechanism and patient satisfaction; radiological outcome of “heterotopic ossification” and satisfaction; functional flexion–extension ROM and satisfaction; and between type of radial head fracture and presence of a radiological outcome.ConclusionThe surgical treatment for the terrible triad of the elbow generally provided satisfactory results, when the functioning of this joint upon the return to activities was taken into consideration

Quantitative histochemistry study of collagen in coracoacromial ligaments of corpses

Foram analisados trinta oito ligamentos coracoacromiais provenientes de dezenove cadaveres, de 12 a 72 anos com media etaria de 40 anos, com o fim de analisar sua mudanca estrutural com o passar da idade e alteracao nas porcoes anatomicas do ligamento. Os especimes foram colhidos e preparados em cortes sagitais para exame a microscopia optica. Com o fim de estudar quantitativamente o colageno empregou-se a coloracao pelo metodo de Picrosirius sob luz polarizada, com analise digital de imagens. O colageno foi quantificado em porcoes anatomicas correspondentes ao terco proximal, medio e distal do ligamento, do lado direito e esquerdo. A quantificacao do colageno se deu pela media de cinco campos opticos analisados, em cada porcao anatomica, com aumento de 10X, atraves da media geometrica dos mesmos. Os dados foram analisados estatisticamente demonstrando nao haver relacao entre a concentracao colagena e a idade e haver maior concentracao colagena na porcao media esquerda em relacao a porcao distal (coracoidea) direitaBV UNIFESP: Teses e dissertaçõe

Estudo transversal sobre os diferentes métodos de tratamento das luxações traumáticas glenoumerais: a cross-sectional study Treatment of traumatic glenohumeral dislocation

OBJETIVO: Verificar como uma população de ortopedistas brasileiros trata a luxação glenoumeral traumática e comparar com os conceitos mais recentes estabelecidos pela literatura. MÉTODOS: Foram distribuídos 200 questionários com 13 questões objetivas sobre a abordagem terapêutica da luxação traumática glenoumeral; 158 foram preenchidos corretamente e aceitos para este estudo. RESULTADOS: A manobra preferida pela maioria foi tração e contratração (60,8%). Dentre os entrevistados, 68,4% declararam obter a redução da luxação glenoumeral na primeira tentativa em mais de 90% dos casos. A primeira tentativa de redução ocorre predominantemente no pronto-socorro (96,5%). Setenta e nove (50,0%) indivíduos relataram não usar nenhuma analgesia antes da redução. A maioria dos participantes imobiliza seus pacientes após a redução (98,1%); desses, 75,4% mantêm seus pacientes imobilizados por duas a três semanas. CONCLUSÕES: De forma geral, o ortopedista brasileiro realiza a redução da luxação glenoumeral com a manobra de tração e contratração. Obtém a redução na primeira tentativa em mais de 90% dos casos e realiza a redução no pronto- socorro. Não utiliza nenhuma analgesia previamente à redução. Imobiliza o paciente com tipoia toracobraquial ou tipoia simples por duas a três semanas.<br>OBJECTIVE: The aim of the present study was to investigate Brazilian orthopedists' opinions regarding the main aspects of the treatment of glenohumeral traumatic dislocation and compare these to literature's current concepts. METHODS: Two hundred questionnaires containing 13 items were randomly distributed to orthopedists who were attending a Brazilian orthopedics congress; 158 were filled in correctly and were considered in this study. RESULTS: The preferred maneuver was traction-countertraction (60.8%). Among the respondents, 68.4% stated that glenohumeral dislocation reduction was achieved in the first attempt in 90% of the cases. The first attempt of reduction occurred mainly in the Emergency room (96.5%). Seventy-nine individuals (50%) reported that they do not use any analgesic prior to reduction. The majority of the participants immobilize their patients after the reduction (98.1%). 75.4% of them keep their patients immobilized from 2 to 3 weeks. CONCLUSION: Generally, Brazilian orthopaedists perform traction-countertraction maneuvers, achieving reduction in the first attempt in more than 90% of the cases in the Emergency room. No previous analgesic agent is used prior to reduction. Immobilization of the patient is made with a Velpeau dressing or a sling for 2 to 3 weeks

Minimally Invasive Osteosynthesis with a Bridge Plate Versus a Functional Brace for Humeral Shaft Fractures

Background: Nonoperative treatment has historically been considered the standard for fractures of the shaft of the humerus. Minimally invasive bridge-plate osteosynthesis for isolated humeral shaft fractures has been proven to be a safe technique, with good and reproducible results. This study was designed to compare clinical and radiographic outcomes between patients who had been treated with bridge plate osteosynthesis and those who had been managed nonoperatively with a functional brace. Methods: A prospective randomized trial was designed and included 110 patients allocated to 1 of 2 groups: surgery with a bridge plate or nonoperative treatment with a functional brace. The primary outcome was the Disabilities of the Arm, Shoulder and Hand ( DASH) score at 6 months. The score on the Short Form-36 (SF-36) life-quality questionnaire, complications of treatment, Constant-Murley score for the shoulder, pain level, and radiographic results were assessed as secondary outcomes. Participants were assessed at 2 weeks1, 2, and 6 monthsand 1 year after the interventions. Results: The mean DASH score of the bridge plate group was statistically superior to that of the functional brace group ( mean scores, 10.9 and 16.9, respectivelyp = 0.046) only at 6 months. The bridge plate group also had a significantly more favorable nonunion rate (0% versus 15%) and less mean residual angular displacement seen on the anteroposterior radiograph ( 2.0 degrees versus 10.5 degrees) ( both p < 0.05). No difference between the groups was detected with regard to the SF-36 score, pain level, Constant-Murley score, or angular displacement seen on the lateral radiograph. Conclusions: This trial demonstrates that, compared with functional bracing, surgical treatment with a bridge plate has a statistically significant advantage, of uncertain clinical benefit, with respect to self-reported outcome ( DASH score) at 6 months, nonunion rate, and residual deformity in the coronal plane as seen on radiographs.FAPESP (Fundacao de Amparo a Pesquisa do Estado de Sao Paulo)Univ Fed Sao Paulo, Escola Paulista Med Unifesp EPM, Dept Orthoped & Traumatol, Div Hand & Upper Limb Surg, Sao Paulo, BrazilUniv Fed Sao Paulo, Escola Paulista Med Unifesp EPM, Dept Orthoped & Traumatol, Div Hand & Upper Limb Surg, Sao Paulo, BrazilWeb of Scienc
