Evaluation of Screws Positioning in Latarjet Surgery: Is There a Correlation between Parallelism to Glenoid and Radiographic Complications? / Avaliação do posicionamento dos parafusos na cirurgia de Latarjet: Existe correlação entre paralelismo à glenoide e complicações radiográficas?

Abstract Objective To evaluate whether the parallelism of screws with glenoid in Latarjet surgery interferes in the positioning of the graft and to verify the reproducibility of a method of measuring screws positioning. Methods Retrospective, multicenter study, of patients with anterior shoulder instability submitted to modified Latarjet surgery and at least one year of postoperative follow-up. Two radiologists analyzed the postoperative tomographic images, acquired in a database, to evaluate the positioning of screws and radiographic complications. Results We evaluated 34 patients, aged between 21 and 60 years, one of them with bilateral shoulder involvement, totaling 35 shoulders evaluated. The tomographic evaluation of the inclination angles of the screws showed no difference between the observers. There was intra- and interobserver agreement to evaluate the following surgical parameters: graft position, presence or not of radiographic complications. Conclusion The technique described for measuring the parallelism of screws in Latarjet surgery presented a very good and excellent intra-observer agreement, respectively. Screw parallelism with glenoid is recommended; however, it is not a mandatory and unique condition to avoid radiographic complications.

The general condition, teaching performance (including theoretical and practical achievements), scores of abilities (including abilities of literature review, lecturing, organization, communication and teamwork), and subjective evaluation scores (learning interests and satisfaction) were analyzed. SPSS 23.0 statistical software was used to conduct independent-sample t-test and chi-square test. Results:The self-directed learning group had higher scores than the control group in the theoretical score [(87.63±7.01) vs. (79.56± 7.08)] and practical score [(86.40±6.45) vs. (82.70±7.65)], literature review score [(16.33±2.45) vs. (14.50±2.27)], the ability of lecturing [(15.56±2.97) vs. (13.90±2.56)], organization [(17.61±2.34) vs. (14.96±2.55)], communication [(17.06±1.91) vs. (14.53±1.96)], and teamwork [(16.23±1.71) vs. (14.76±2.32)], as well as the indicators of learning interest and levels of satisfaction (teaching form and teaching effect), with significant differences between the two groups ( P<0.05). Conclusion:The self-directed learning teaching model can inspire students' initiative, improve teaching quality, and contribute to new ideas for teaching reform.

Postoperative Comparative Evaluation of Patients Undergoing Surgical Treatment for Acute Versus Chronic Acromioclavicular Dislocations / Avaliação pós-operatória comparativa dos pacientes submetidos ao tratamento cirúrgico das luxações acromioclaviculares aguda versus crônica

Abstract Objectives The present study evaluates and compares the surgical treatment of acute and chronic acromioclavicular dislocations (ACDs) to define the most effective therapeutic plan. Methods A retrospective study consisting of 30 patients submitted to the surgical treatment of types III and V ACDs between 2011 and 2018; the subjects were separated according to a temporal classification in acute (< 3 weeks; subgroup I) and chronic (> 3 weeks; subgroup II) subgroups. All patients underwent a postsurgical evaluation with a standardized protocol containing epidemiological, functional, and radiological data. Results Subgroup I presented a visual analog scale (VAS) score of 1.10, a Constant-Murley score of 92.3, and a University of California at Los Angeles (UCLA) Shoulder Rating score of 33.5. The coracoclavicular (CC) distance was of 11.0 mm, and the average increase in CC space was lower than 8.9% compared to the contralateral shoulder. In subgroup II, the VAS score was of 1.11, the Constant-Murley score was of 94.2, and the UCLA score was of 32.4. The CC distance was of 13.8 mm, with a 22.9% increase in CC space compared to the contralateral side. Conclusion Although there was no significant difference between the evaluated items, subgroup I tended to present a lower CC distance (p = 0.098) and a lower percentage increase in CC distance (p = 0.095) compared to subgroup II. Thus, the surgical treatment must be performed within three weeks after the trauma to try to avoid such trend. If the acute treatment is not possible, the modified Weaver Dunn technique has good clinical and functional outcomes.

Resumo Objetivos Avaliar e comparar os resultados do tratamento cirúrgico das luxações acromioclaviculares (LACs) aguda e crônica, definindo o plano terapêutico mais eficaz. Métodos Estudo retrospectivo realizado com 30 pacientes operados entre 2011 e 2018 para LAC tipos III e V, separados de acordo com a classificação temporal em subgrupo agudo (< 3 semanas; subgrupo I) e subgrupo crônico (> 3 semanas; subgrupo II). Todos os pacientes foram submetidos a avaliação pós-cirúrgica com protocolo padronizado composto por dados epidemiológicos, funcionais e radiográficos. Resultados No subgrupo I, a pontuação na escala visual analógica (EVA) foi de 1,10, o escore de Constant-Murley foi de 92,3, e o escore da University of California at Los Angeles (UCLA) foi de 33,5. A distância coracoclavicular (CC) foi de 11,0 mm, e o aumento do espaço CC foi em média menor do que 8,9% em relação ao ombro contralateral. No subgrupo II, a EVA foi de 1,11, o escore de Constant-Murley foi de 94,2, e o da UCLA, 32,4. A distância CC foi de 13,8 mm, sendo o aumento do espaço CC de 22,9% em relação ao contralateral. Conclusão Apesar de não ter havido diferença significativa entre os quesitos avaliados, houve uma tendência de o subgrupo agudo apresentar distância CC (p = 0,098) e percentual de aumento da distância CC (p = 0,095) menor do que o subgrupo crônico. Assim, é interessante que o tratamento cirúrgico seja realizado nas primeiras três semanas após o trauma, para tentar evitar essa tendência. Nos casos em que não for possível realizar o tratamento na fase aguda, a técnica de Weaver Dunn modificada apresenta bons resultados clínicos e funcionais.

Application of digital technology in diagnosis and treatment of dentofacial deformities / 口腔疾病防治

@#Dento-maxillofacial deformity refers to an abnormal relationship of the volume or shape of the upper and lower jaw bones with the other bones of the craniofacial area. Its correction mainly involves hard tissues, such as the jaws and teeth. In recent years, digital techniques based on virtual surgery, real-time navigation, and 3D printing have developed rapidly in the area of craniomaxillofacial surgery. Digital technology has advantages for preoperative diagnosis, surgical plan formulation, surgical simulation, intraoperative navigation, effect prediction, doctor-patient communication, and young physician training. The Department of Orthognathic and TMJ Surgery of West China Hospital of Stomatology, Sichuan University, has conducted digitized diagnosis and treatment of dento-facial deformities since 2008 and has established a digital center for the treatment of dentofacial deformities based on equipment such as spiral CT, dental arch laser scanners, facial 3D cameras, virtual surgery software, 3D printers, and sleep-breathing monitoring. The result is a diagnostic and treatment protocol for dentofacial deformity specific to the characteristics of the population of West China. This article combines the latest domestic and foreign literature and comprehensively introduces the application of digital technology for the diagnosis and treatment of dental and maxillofacial deformities.

Terrible triad of the elbow: functional results of surgical treatment / Tríade terrível do cotovelo: resultados funcionais do tratamento cirúrgico

ABSTRACT Objective: To evaluate the functional and radiographic results of patients who underwent surgical treatment for terrible triad-type elbow injuries (TTE). Methods: We retrospectively evaluated 20 patients, including one case with bilateral injuries (total of 21 elbows) that were surgically treated from January 2004 to July 2014. We evaluated the functional results of treatment by measuring the restored range of motion (ROM) of the elbow, using the DASH (Disabilities of the Arm, Shoulder and Hand) and MEPS (Mayo Elbow Performance Score) scores. Complications and the development of osteoarthritis and heterotopic ossification (HO) were also evaluated. Results: Eight elbows (38%) required additional surgical treatment; HO was observed in eight elbows (38%) and severe osteoarthritis (Broberg-Morrey type IV) was seen in only one case (4%). Nevertheless, we obtained good functional results, 14.27 on the DASH and 84 on the MEPS. The average ROM for flexion-extension was 101° (20-140°) and for pronation-supination was 112.85° (0-180°). Conclusion: When TTE injuries are treated systematically, even despite variations in these injuries, functional ROM and scores ranging from good to excellent can be obtained. Level of Evidence IV, Case Series.

RESUMO Objetivo: Avaliar os resultados funcionais e radiográficos dos pacientes que sofreram lesões do tipo tríade terrível do cotovelo (TTC) e foram tratados cirurgicamente. Métodos: Foram avaliados retrospectivamente 20 pacientes, um caso com lesão bilateral (21 cotovelos), que foram tratados cirurgicamente no período de janeiro de 2004 a julho de 2014. Os resultados funcionais do tratamento foram avaliados pela medida da restauração do arco de movimento (ADM) do cotovelo, de acordo com os escores DASH (Disabilities of the Arm, Shoulder and Hand) e MEPS (Mayo Elbow Performance Score). Além da presença de complicações, avaliou-se osteoartrose e ossificação heterotópica (OH). Resultados: Oito cotovelos (38%) foram submetidos a novo procedimento cirúrgico; observou-se OH em oito cotovelos (38%) e apenas um caso (4%) de artrose grave (tipo IV de Broberg-Morrey). Apesar disso, foram obtidos bons resultados funcionais, DASH de 14,27 e MEPS de 84. E o ADM médio de flexão-extensão foi de 101o (20o e 140o) e de pronação-supinação, 112,85o (0o até 180o). Conclusão: Quando se realiza tratamento sistematizado nas lesões do tipo TTC, mesmo com suas variações, pode-se obter um ADM funcional e escore funcional entre bom e excelente. Nível de Evidência IV, Série de Casos.

Analysis of postoperative monitoring of patients undergoing shoulder arthroscopy for anterior instability / Análise do monitoramento pós-operatório dos pacientes submetidos à artroscopia do ombro para tratamento de instabilidade anterior

ABSTRACT OBJECTIVE: Analyze the postoperative follow-up of patients undergoing shoulder arthroscopy for treatment of anterior instability and correlate with the prevalence of recurrence. METHODS: A six-question survey was applied by phone and mail to 65 patients, seeking information on the current result of the surgical procedure. All patients were treated arthroscopically for anterior shoulder instability, with at least 12 months of postoperative time. Patients with associated posterior labial lesions and revision surgeries were not included. RESULTS: At the time of the survey the patients had a median of 56 (IQR: 34.5-110.5) postoperative months. The mean sample age was 24.6 years (maximum = 47, minimum = 12; SD = 7.3). Complaint of pain in the shoulder was observed in 20 patients (30.7%). Dislocation recurrence was observed in 10 patients (15.3%). Forty-four patients (67.6%) considered their shoulder normal, which was more frequent in non-recurrence patients (p< 0.001). Forty-three patients (66.1%) returned to their previous level of sport and there was no difference between recurrence and non-recurrence patients (p= 0.456). It was found that the prevalence of recurrence was 5.6 (95% CI: 1.30-24.46) times higher in individuals who abandoned monitoring before six months postoperatively (p= 0.012). CONCLUSION: The abandonment of postoperative monitoring in the early stages, when the patients receive orientation for muscle strengthening, proprioceptive education, and dangerous movements to avoid, can increase the rates of recurrent shoulder dislocation in patients treated for anterior instability by arthroscopy.

RESUMO OBJETIVO: Analisar o acompanhamento pós-operatório dos pacientes submetidos à artroscopia do ombro para tratamento de instabilidade anterior e correlacionar com a prevalência de recidiva. MÉTODOS: Foi aplicado em 65 pacientes, através de ligação telefônica, um questionário que buscava informações sobre a situação atual do resultado do procedimento cirúrgico. Todos os pacientes foram operados para corrigir uma instabilidade anterior do ombro por artroscopia e tinham pelo menos 12 meses de pós-operatório. Não foram incluídos pacientes com associação de lesão labral posterior e cirurgias de revisão. RESULTADOS: O questionário foi aplicado com uma mediana de 56 (IIQ: 34,5 a 110,5) meses. A média de idade da amostra foi de 24,6 anos (máxima de 47 e mínima de 12 - DP 7,3). Foi verificada queixa de dor em 20 pacientes (30,7%) e recidiva da luxação em dez (15,3%). 44 pacientes (67,6%) consideraram seu ombro normal e 43 (66,1%) retornaram ao esporte prévio. Foi verificado que os indivíduos que abandonaram o acompanhamento pós-operatório antes dos seis meses tiveram uma prevalência 5,6 (IC 95%: 1,30-24,46) vezes maior de recidiva (p = 0,012). CONCLUSÃO: O abandono do acompanhamento pós-operatório na fase inicial, na qual o paciente recebe orientações para o reforço muscular e a educação proprioceptiva, pode colaborar no aumento do índice de recidiva da luxação nos pacientes tratados por artroscopia.

In situ repair of partial articular surface lesions of the supraspinatus tendon / Técnica de reparo in situ das lesões parciais da superfície articular do tendão do supraespinal

ABSTRACT OBJECTIVE: To demonstrate the in situ repair technique of high-degree partial-thickness articular surface lesions of the supraspinatus tendon (SS). The procedure consists of the arthroscopic surgical repair of these lesions, without the need to complete the lesion, as occurs in traditional classical technique. A small incision is made in the longitudinal direction of the intact bursal fibers and where bone fixation anchors are introduced, which makes the procedure easier. These anchors are transferred to the tendon and thus enable the repair of the lesion. METHODS: 48 shoulders were operated in the period 2010-2015. The minimum follow-up was 12 months and maximum 60 months. Ages ranged from 38 years to 75 years (mean 54 years). They were indicated for the repair of high-degree symptomatic lesions and at least 30% intact superior bursal fibers of good quality. RESULTS: Patients were evaluated according to the UCLA criteria, the results were: 69% excellent, 17% good, 7% fair, and 7% poor. Fair results occurred in three patients with associated symptoms of polyarthralgia who remained with residual pain. Three patients developed postoperative joint stiffness (7%). CONCLUSION: The procedure under study is safe and easy to reproduce. It shows high rates of positive results (86%). The opening made in the bursal side of the SS tendon allowed the arthroscope to remain in the subacromial space, making it easier to perform surgery.

RESUMO OBJETIVO: Demonstrar a técnica de reparo in situ das lesões de espessura parcial da superfície articular de alto grau do tendão do supraespinal (SE). O procedimento consiste no reparo cirúrgico dessas lesões por via artroscópica, sem a necessidade de completar a lesão, como ocorre na técnica clássica tradicional. É feita uma pequena incisão longitudinal no sentido das fibras intactas bursais, por onde são introduzidas as âncoras de fixação óssea, o que torna mais fácil o procedimento. Essas âncoras são transferidas para o tendão e assim se faz o reparo da lesão. MÉTODOS: Foram operados 48 ombros de 2010 a 2015. O seguimento mínimo foi de 12 meses e o máximo de 60. A idade variou de 38 anos a 75 (média de 54). Foram indicadas para o reparo as lesões sintomáticas de alto grau que apresentassem pelo menos 30% da fibras superiores bursais intactas e de boa qualidade. RESULTADOS: Os pacientes foram avaliados segundo os critérios da Universidade da Califórnia em Los Angeles (UCLA), obtiveram-se resultados excelentes em 69%, bons em 17%, razoáveis em 7% e ruins em 7%. Os resultados razoáveis ocorreram em três pacientes que apresentavam sintomas associados de poliartralgia e permaneceram com dor residual. Três pacientes desenvolveram rigidez articular no pós-operatório (7%). CONCLUSÃO: O procedimento em estudo é seguro e de fácil reprodutibilidade e apresenta altos índices de resultados positivos (86%). A abertura feita no lado bursal do tendão do SE permitiu a manutenção do artroscópio no espaço subacromial e tornou mais fácil a cirurgia.

Ischiofemoral Impingement Syndrome: Outcomes of Endoscopic Resection of the Lesser Trochanter

Ischiofemoral impingement syndrome is a rare clinical entity characterized by chronic groin, buttock or hip pain associated with radiographic evidence of narrowing of the space between the lesser femoral trochanter and the ischial tuberosity. Introduction of magnetic resonance imaging to the clinical practice as well as the establishment of the radiological definition of the abnormal ischiofemoral distance has led to an increasing interest in this condition. Ischiofemoral impingement syndrome is a poorly understood disorder of chronic pain, especially regarding its treatment. The authors present two cases of primary ischiofemoral impingement syndrome successfully treated with a minimally invasive surgical technique. With this endoscopic technique, it was possible to resect the lesser trochanter and restore the ischiofemoral space. Immediate clinical and functional improvement was reported by both patients.

PREFERED SURGICAL TECHNIQUE USED BY ORTHOPEDISTS IN ACUTE ACROMIOCLAVICULAR DISLOCATION

ABSTRACT Objective: To determine whether training on shoulder and elbow surgery influences the orthopedist surgeons' preferred technique to address acute acromioclavicular joint dislocation (ACD). Methods: A survey was conducted with shoulder and elbow specialists and general orthopedists on their preferred technique to address acute ACD. Results: Thirty specialists and forty-five general orthopedists joined the study. Most specialists preferred the endobutton technique, while most general orthopedists preferred the modified Phemister procedure for coracoclavicular ligament repair using anchors. We found no difference between specialists and general orthopedists in the number of tunnels used to repair the coracoclavicular ligament; preferred method for wire insertion through the clavicular tunnels; buried versus unburied Kirschner wire insertion for acromioclavicular temporary fixation; and time for its removal; and regarding the suture thread used for deltotrapezoidal fascia closure.

ABSTRACT OBJECTIVE: The posterosuperior shoulder access used in surgical treatment for acromioclavicular dislocation was constructed through dissection of 20 shoulders from 10 recently chilled adult cadavers, and the distances from this route to the nearby neurovascular structures were analyzed. METHODS: A Kirschner wire was introduced into the top of the base of the coracoid process through the posterosuperior shoulder access, in the area of the origin of the conoid and trapezoid ligaments, thus reproducing the path for inserting two anchors for anatomical reconstruction of the coracoclavicular ligaments. The smallest distance from the insertion point of the Kirschner wire to the suprascapular nerve and artery/vein was measured. RESULTS: The mean distance from the suprascapular nerve to the origin of the coracoclavicular ligaments at the top of the base of the coracoid process was 18.10 mm (range: 13.77-22.80) in the right shoulder and 18.19 mm (range: 12.59-23.75) in the left shoulder. The mean distance from the suprascapular artery/vein to the origin of the coracoclavicular ligaments was 13.10 mm (range: 9.28-15.44) in the right shoulder and 14.11 mm (range: 8.83-18.89) in the left shoulder. Comparison between the contralateral sides did not show any statistical difference. CONCLUSION: The posterosuperior shoulder access route for anatomical reconstruction of the coracoclavicular ligaments in treating acromioclavicular dislocation should be performed respecting the minimum limit of 8.83 mm medially.

RESUMO OBJETIVO: Os autores fizeram o acesso posterossuperior do ombro usado no tratamento cirúrgico da luxação acromioclavicular, a partir da dissecção de 20 ombros de 10 cadáveres adultos recém-resfriados, e analisaram as distâncias da via às estruturas neurovasculares próximas. MÉTODOS: Introduziu-se um fio de Kirschner no topo da base do processo coracoide pelo acesso posterossuperior do ombro, na área de origem dos ligamentos conoide e trapezoide, para reproduzir o trajeto da inserção de duas âncoras para reconstrução anatômica dos ligamentos coracoclaviculares. Mediu-se a menor distância do ponto de inserção do fio de Kirschner ao nervo e à artéria/veia supraescapular. RESULTADOS: A média da distância do nervo supraescapular até a origem dos ligamentos coracoclaviculares no topo da base do processo coracoide foi de 18,10 mm (13,77 a 22,80) no ombro direito e 18,19 mm (12,59 a 23,75) no ombro esquerdo. A média da distância da artéria/veia supraescapular até a origem dos ligamentos coracoclaviculares foi de 13,10 mm (09,28 a 15,44) no ombro direito e 14,11 mm (08,83 a 18,89) no ombro esquerdo. Não houve diferença estatística comparativa entre os lados contralaterais. CONCLUSÃO: A via de acesso posterossuperior do ombro para reconstrução anatômica dos ligamentos coracoclaviculares no tratamento das luxações acromioclaviculares deve ser feita com respeito ao limite de 08,83 mm medialmente.

Congenital dislocation of the patella - clinical case / Luxação congênita da patela - Caso clínico

Congenital patellar dislocation is a rare condition in which the patella is permanently dislocated and cannot be reduced manually. The patella develops normally as a sesamoid bone of the femur. This congenital dislocation results from failure of the internal rotation of the myotome that forms the femur, quadriceps muscle and extensor apparatus. It usually manifests immediately after birth, although in some rare cases, the diagnosis may be delayed until adolescence or adulthood. Early diagnosis is important, thereby allowing surgical correction and avoiding late sequelae, including early degenerative changes in the knee. A case of permanent dislocation of the patella is presented here, in a female child aged seven years.

A luxação congênita da patela é uma patologia rara, em que a patela se encontra permanentemente luxada e manualmente irredutível. A patela desenvolve-se normalmente como um osso sesamoide do fêmur. A luxação congênita da patela resulta da falência da rotação interna do miótomo que forma o fêmur, músculo quadricípite e o aparelho extensor. Usualmente manifesta-se imediatamente após o nascimento, embora em alguns casos raros o diagnóstico possa ser adiado até a adolescência/idade adulta. O diagnóstico precoce é importante, permite a correção cirúrgica, evita as sequelas tardias, notadamente alterações degenerativas precoces do joelho. É apresentado um caso de luxação permanente da patela, numa criança de sexo feminino, com sete anos.

lmpact of combined surgery on the MUC5 AC levels in patients with glaucoma and cataract / 国际眼科杂志(Guoji Yanke Zazhi)

Abstract?AlM:To investigate the effects of the MUC5AC levels and ocular function of the patients with glaucoma and cataract with combined surgery.? METHODS: Twenty - eight patients treated with glaucoma and cataract combined surgery were chosen as the observation group from December 2011 to June 2014 in our hospital, and other 28 cases of glaucoma and cataract did not undergo surgical treatment were selected as the control group, 30 healthy subjects were as healthy control group. the MUC5AC level and ocular surface score of the three subjects before surgery 1d, after 3 and 6mo were compared.?RESULTS: The NUC5AC of the two groups of patients was significantly lower than that of the healthy control group before surgery (P<0. 05), the ocular function score was significantly higher than the healthy control group ( P<0. 05). After 1mo, the MUC5AC of the observation group were significantly lower than that of before surgery ( P<0. 05), after 3mo MUC5AC content gradually increased to preoperative levels, after 6mo the MUC5AC were significantly higher than before surgery (P<0. 05). After 1mo, ocular function scores were significantly higher than the preoperative ( P< 0. 05 ), while after 3mo, ocular function scores decreased after 6mo of ocular surface function scores were significantly lower than the preoperative (P<0. 05). While the control group after 6mo, with the passage of time, the MUC5AC content gradually reduce, ocular function score increased gradually. ?CONCLUSlON:To treat the patients with glaucoma and cataract with combined surgery, the level of MUC5AC can temporary decrease. Ocular function score can temporary increase in, but after 3mo, it can be gradually improved.

Concept of healing of recurrent shoulder dislocation

This paper presents the main surgical techniques applied in the treatment of anterior recurrent shoulder dislocation, aiming the achievement of the normality of articulate movements. This was obtained by combining distinct surgical procedures, which allowed the recovery of a complete functional capacity of the shoulder, without jeopardizing the normality of movement, something that has not been recorded in the case of the tense sutures of the surgical procedures of Putti-Platt, Bankart, Latarjet, Dickson-O'Dell and others. The careful review of the methods applied supports the conclusion that recurrent shoulder dislocation can be cured, since cure has been obtained in 97% of the treated cases. However, some degree of limitation in the shoulder movement has been observed in most of the treated cases. Our main goal was to achieve a complete shoulder functional recovery, by treating simultaneously all of the anatomical–pathological lesions, without considering the so-called essential lesions. The period of post-operatory immobilization only last for the healing of soft parts; this takes place in a position of neutral shoulder rotation, since the use of vascular bone graft eliminates the need for long time immobilization, due to the shoulder stabilization provided by rigid fixation of the coracoid at the glenoid edge, as in the Latarjet's technique. Our procedure, used since 1959, comprises the association of several techniques, which has permitted shoulder healing without movement limitation. That was because of the tension reduction in the sutures of the subescapularis, capsule, and coracobraquialis muscles...

O presente trabalho analisa as principais técnicas cirúrgicas empregadas no tratamento da luxação recidivante do ombro (LRO), com o objetivo de obter a normalidade da amplitude dos movimentos articulares e associar diferentes tempos cirúrgicos num único procedimento para obter uma capacidade funcional completa, sem comprometer a normalidade dos movimentos, por causa das suturas tensas usadas nas cirurgias de Putti-Platt, Bankart, Latarjet, Dickson-O'Dell e outras. Após cuidadosa revisão desses métodos em uso, chegamos à conclusão de que a LRO pode ser considerada resolvida quanto à porcentagem de cura (97%). Permanecem, no entanto, limitações dos movimentos na grande maioria dos casos, aceitas até como necessárias para evitar recidivas. O nosso objetivo cirúrgico visa à obtenção de uma recuperação funcional completa, atuar simultaneamente sobre as várias lesões anatomopatológicas e abandonar a ideia das chamadas "lesões essenciais". A imobilização do ombro operado será feita somente durante a cicatrização das partes moles em rotação neutra. Com o uso de um enxerto ósseo pediculado dispensa-se qualquer tipo de imobilização prolongada, por causa da estabilidade obtida pela osteossíntese da coracoide no rebordo da glenoide, como na técnica de Latarjet. Essa nossa conduta, empregada desde 1959, consiste, portanto, na associação das várias técnicas com as quais se obtêm a cura sem limitação dos movimentos, por causa da redução da tensão nas suturas da cápsula e dos músculos subescapular e coracobraquial empregadas nas técnicas acima...
