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 ( 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.

To evaluate the functional and radiographic results of patients who underwent surgical treatment for terrible triad-type elbow injuries (TTE).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.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°).When TTE injuries are treated systematically, even despite variations in these injuries, functional ROM and scores ranging from good to excellent can be obtained.Avaliar os resultados funcionais e radiográficos dos pacientes que sofreram lesões do tipo tríade terrível do cotovelo (TTC) e foram tratados cirurgicamente.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).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 101Quando 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.

Introduction and importance Surgical treatment for clavicle injuries is indicated for displaced and shortened fractures. Osteosyntheses with plate fixation may present with complications in 6.3% to 8.5% of patients. Peri-implant clavicle fractures (PIF) are rare, and we have not found any previous cases in our literature search. Case presentation A 25-year-old male with previously (six years earlier) surgically treated clavicle fracture presented with a peri-implant clavicle fracture requiring surgical treatment. The management involved overlaying an implant to fix the lateral clavicle fracture without removing the previous plate. Complete bone healing was observed without any further complication. Clinical discussion Despite the low rate of implant failure in clavicle fractures, this complication occurs mainly in elderly patients with poor bone quality. No PIF have been described in the literature prior to this. This case report demonstrates a young patient with good bone quality and previous fracture fixation presenting with PIF which has now shown complete bone healing. Conclusion In this case, overlying an additional plate on the lateral clavicle portion without removing the previous plate increased the stability of the fracture. It demonstrates the value of overlaying plate osteosyntheses for patients with clavicle PIF., Highlights • Peri-implant clavicle fracture is a rare situation. • The management of peri-implant fracture is challenging. • Overlaying plate fixation can be the solution for peri-implant clavicle fractures.

Objective: To determine: 1) whether the patients had been oriented to use immobilization for at least four weeks and which type of immobilization was prescribed, 2) how many dislocations occurred until the patient received information about the need of surgery, 3) How long it takes for patients to have an appointment with a shoulder surgeon, 4) How many dislocations the patient had at the time of surgery. Material and Methods: Of the 100 patients surgically treated or waiting for surgery at outpatient facilities, we interviewed 61 patients with questions related to the mechanism of dislocation, emergency service sites, guidelines for acute event treatment and follow-up, time elapsed until surgery and follow-up. Collected data were submitted to analysis. Results: Only 13 patients (22%) had received correct information about their lesion, prognosis concerning recurrence, and about the need of surgery and expert follow-up in recurrent cases. None of our patients received proper information about type and duration of immobilization. Conclusion: None of our patients had received proper orientation to remain immobilized for four weeks, and the types of immobilization vary from a handmade sling to a manufactured Velpeau. Most of our patients (78%) did not receive proper orientation about specialized follow-up and surgery after their second episode of dislocation. The time for a specialized appointment with shoulder surgeon ranges from four to six months, with 1-100 dislocation episodes at the moment of surgery.

Objective: To evaluate the clinical and functional outcomes from arthroscopic repairs on small and medium-sized tears of the supraspinatus muscle tendon. Methods: 129 cases of isolated small and medium tears of the supraspinatus muscle tendon were evaluated retrospectively. The average duration of pain was 29 months. The average joint range of motion comprised active elevation of 136°, lateral rotation of 58° and medial rotation at T12 level; and the preoperative functional UCLA score averaged 17 points. In all the cases, complete repair could be achieved. Results: The average score on the UCLA functional scale in the postoperative period was 32 points. The average length of follow-up was 39 months. Seventy-five cases (58%) had excellent results and 42 (32%) had good results. The average final active elevation was 156° with an average gain of 20°, and the average final lateral rotation was 57° with an average gain of 9°. Both of these were statistically significant (P < 0.05). The patients who underwent tenotomy of the long head of the biceps (LHB), with or without tenodesis, did not present statistically inferior functional outcomes, in comparison with the patients who only underwent decompression and lesion repair (P = 1.00). Fourteen cases (10.8%) presented complications during the postoperative period. Six (4.6%) developed adhesive capsulitis and four (3.1%) presented re-rupture of the tendon, proven by means of magnetic resonance imaging. Conclusions: Arthroscopic repair of small and medium tears of the supraspinatus muscle tendon provided a functional clinical improvement, with good and excellent results in 90% of the cases.

Objective: To compare the functional results among patients undergoing tenotomy with or without tenodesis of the long head of the biceps associated with arthroscopic repair of rotator cuff injuries, with a minimum two-year follow-up. Method: This was a retrospective non-randomized trial with evidence level III, in which the medical files of 77 patients with lesions of the long head of the biceps were reviewed and clinically reassessed. Among these, 55 patients underwent tenotomy without tenodesis and 22 underwent tenotomy with tenodesis, with outpatient follow-up for at least two years. The age, dominant side, operated side, lesion size using the Gartsman classification, pre and postoperative range of motion, presence or absence of the Popeye sign, pain in the bicipital groove and assessments using the University of California at Los Angeles (UCLA) score and the elbow strength index. Results: The mean UCLA score of the sample went from 16.92 (range: 8 to 25) to 31.45 (range: 13 to 35) (p < 0.001). Comparison of the pre and postoperative UCLA scores in the two groups showed that the difference in the group with tenotomy and tenodesis was 15.95 and in the group with tenotomy alone, 14.62 (p = 0.023). However, there was no statistical significance in comparing the groups regarding pain in the bicipital groove, Popeye sign or elbow strength index. Conclusion: This study showed that the difference in UCLA scores was statistically significant. The group with tenotomy and tenodesis of the long head of the biceps presented better functional results.

Purpose: The purpose of this study was to determine the effect of coracoid tunnel size and location on the biomechanical characteristics of cortical button fixation for coracoclavicular ligament reconstruction. Methods: Thirteen matched pairs of cadaveric scapulae were used to determine the effects of coracoid tunnel size, and 6 matched pairs were used to determine the effects of coracoid tunnel location. For tunnel size, a 4.5-mm hole was drilled in the base of the coracoid of one scapula and a 6-mm hole was drilled in the contralateral scapula. For tunnel location, 2 holes were drilled: (1) The first group received a hole centered in the coracoid base and a hole 1.5 cm distal from the first, along the axis of the coracoid. (2) The second group received holes that were offset anteromedially from the first set of holes (base eccentric and distal eccentric). A cortical buttonesuture tape construct was placed through each tunnel, and constructs were then loaded to failure. Results: For tunnel size specimens, load at ultimate failure was significantly greater for the 4.5-mm group compared with the 6-mm group (557.6 � 48.5 N v 466.9 � 42.2 N, P < .05). For tunnel location, load at ultimate failure was significantly greater for the centered-distal tunnel group compared with the eccentric-distal group (538.1 � 70.2 N v 381.0 � 68.6 N, P < .05). Conclusions: A 4.5-mm tunnel in the coracoid provided greater strength for cortical button fixation than a 6-mm tunnel. In the distal coracoid, centered tunnels provided greater strength than eccentric tunnels. Clinical Relevance: When performing cortical button fixation at the coracoid process for coracoclavicular ligament reconstruction, a 4.5-mm tunnel provides greater fixation strength than a 6-mm tunnel. The base of the coracoid is more forgiving than the distal coracoid regarding location.

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.

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.

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.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.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 %).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.

Background:The coracoid has been widely used as a graft to reconstruct anterior glenoid bone defects, as described by the Latarjet and Bristow procedures, with successful results. Nevertheless, at the present, there are no studies correlating the size of the coracoid graft and its relation to the glenoid.Purpose:To assess the mediolateral (M-L) and anteroposterior (A-P) thickness of the coracoid process as well as the widest anterior-to-posterior glenoid distance (glenoid width) and to analyze the correlation between these measurements, while comparing these with the A-P coracoid process thickness.Study Design:Descriptive laboratory study.Methods:Sixty-one unpaired, adult human cadaveric scapulae were evaluated. Three examiners performed 3 independent measurements of the largest M-L thickness of the coracoid process and also the widest anterior-to-posterior distance of the glenoid. The A-P coracoid process thickness was also measured to compare for correlations with M-L coracoid thickness.Results:The glenoid width was 26.38 ± 2.69 mm (range, 20.03-32.35 mm), and the M-L coracoid thickness was 14.51 ± 1.90 mm (range, 9.60-19.31 mm). Calculating the ratio between the M-L thickness of the coracoid and glenoid width, we observed that the coracoid represented 43% to 70% of the glenoid width (54% on average). The A-P coracoid process thickness was 8.37 ± 0.93 mm (range, 6.61-9.76 mm), representing 31% of the glenoid width on average.Conclusion:A strong positive and statistically significant relationship between the coracoid process M-L thickness and the anterior-to-posterior glenoid width exists; the coracoid represents, on average, 54% of the glenoid width.Clinical Relevance:Most cases of glenoid bone loss in recurrent shoulder dislocation can be reconstructed with the coracoid process to re-establish its anatomy.

OBJETIVO: Comparação dos resultados funcionais nos pacientes submetidos à tenotomia com ou sem tenodese da CLB associada ao reparo da lesão do manguito rotador por visão artroscópica, com seguimento superior a dois anos. MÉTODO: Estudo retrospectivo não randomizado, com nível de evidência III, em que foram revisados os prontuários e realizada reavaliação clínica de 77 pacientes com lesão da cabeça longa do bíceps, sendo que 55 foram submetidos à tenotomia sem tenodese e 22 à tenotomia com a tenodese, com seguimento ambulatorial maior que dois anos. Foram avaliados idade, dominância, lado operado, tamanho das lesões classificadas por Gartsman, arco do movimento pré e pós-operatório, presença ou ausência do sinal do Popeye, dor na corredeira bicipital, avaliação segundo a escala University of California at Los Angeles e Elbow Strength Index. RESULTADOS: O UCLA médio total da amostra foi de 16,92 (8 a 25) para 31,45 (13 a 35) (p < 0,001). Comparando a variação do UCLA pré com o pós-operatório entre os dois grupos, nos pacientes submetidos à tenotomia com a tenodese esta variação foi de 15,95 e nos pacientes submetidos somente à tenotomia a variação foi de 14,62 (p = 0,023). No entanto, não houve significância estatística na comparação entre os grupos quanto à dor na corredeira bicipital, sinal do Popeye e Elbow Strength Index. CONCLUSÃO: O estudo apresentou diferença estatística na variação do UCLA. O grupo em que foi realizada a tenotomia com a tenodese da CLB apresentou melhores resultados funcionais.

Objective: To describe the initial experience of four orthopedic clinics from using Bi-Contact® total elbow arthroplasty (TEA), reporting the results and complications of the procedure. Methods: This was a retrospective study, through analysis on the medical records of patients who underwent primary TEA using a prosthesis model developed in conjunction with IOT-HCFMUSP. Forty-six elbows (45 patients) that were operated at four orthopedic clinics between 2000 and 2009 were evaluated. Results: The majority of the patients were female (74%), and the median age was 62.5 years. The diagnoses encountered were trauma sequelae (47.83%), rheumatoid arthritis (32.61%), primary osteoarthrosis (8.7%), acute fractures (6.52%) and heterotopic ossification (2.17%). The median length of follow-up was 2.08 years (0.25-9). The procedure significantly alleviated pain and improved range of motion. It was observed that at least one complication was present in 69.57% of the cases, and the main ones were infection (28.26%), need for revision (28.26%), intraoperative fracture (15.22%) and aseptic loosening (15.22%). Conclusion: Bi-Contact® TEA provided significant alleviation of pain and improvement of range of motion in the present series. The complication rate was high, and the most frequently observed complications were infection, aseptic loosening and intraoperative fracture.

Objective: To analyze whether the Bernageau radiographic view is adequate for studying the anterior glenoid rim and to determine the distance between the posterior and anterior glenoid rims. Methods: Fifty patients (31 males) with a mean age of 34 years were evaluated by positioning their arm at 160° forward flexion and body at 70° to the x-ray chassis, while positioning the x-ray tube at 30° craniocaudally, centered on the scapula spine. Three of the authors measured the distance between the posterior and anterior glenoid rim three times. The variability and reproducibility of this distance were studied. Three shoulder surgeons performed a subjective evaluation by answering whether it was possible to evaluate the anterior glenoid rim in the view studied. Results: The mean distance was 24.48 mm ± 0.332 mm (left) and 24.82 mm ± 0.316 mm (right). The Anderson-Darling test showed that the measurements had normal distribution, and Pearson's correlation showed significant reproducibility (P < 0.01). The first observer found that 67% of the x-ray images were suitable for evaluating the anterior glenoid rim. The second found that 81% were suitable and the third, 78%. The kappa coefficient showed that the second and third observers had substantial agreement of opinion. Conclusion: The Bernageau view provided a suitable x-ray image for studying the anterior glenoid rim and for assessing erosion after comparison with the unaffected side.

As glenoid bone erosion has been related to high rates of recurrence after traditional Bankart repair, the necessity to diagnose existing bone loss is fundamental to avoiding the recurrence of shoulder dislocation. There are many techniques described in the literature explaining how to calculate glenoid bone loss; however, there are only few articles, which shows the usefulness of the x-rays for that purpose. Moreover, just one of these papers described the reliability of a specific x- ray view to measure the percentage of a glenoid bony defect, comparing it with the computed tomography scan and known glenoid osteotomy. The aim of this study was to describe a reliable and reproducible technique for calculating glenoid bone loss using the Bernageau x-ray profile view and to show the results of a earlier study in which we calculated the distance between the posterior and anterior glenoid rim on the Bernageau profile view and compared this measurement between the right and the left shoulders. This technique is cheaper than the computed tomography scan and is easier to perform.

Objective: To evaluate the efficacy of suprascapular nerve block in combination with the infusion of anesthetic into the sub-acromial space compared to an interscalene block. Methods: Forty-five patients with small or medium isolated supraspinatus tendon lesions who underwent arthroscopic repair were pro-spectively 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-inflam-matory, 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.

OBJETIVO: Analisar se a incidência radiográfica de Bernageau é adequada para estudar a borda anterior da glenoide e determinar a distância entre a borda anterior e posterior da glenoide. MÉTODO: Cinquenta pacientes (31 do sexo masculino) com idade média de 34 anos, foram avaliados posicionando-se o braço em flexão anterior de 160º e o corpo a 70º do chassi radiográfico, enquanto o posicionamento da ampola de raios-X era de 30º crânio-caudal, centrada na espinha da escápula. Dos autores, três mensuraram três vezes a distância entre a borda anterior e posterior da glenoide. Foram estudadas a variabilidade e a reprodutibilidade dessa distância. Três cirurgiões de ombro realizaram uma avaliação subjetiva, respondendo se era possível a avaliação da borda anterior da glenoide na incidência estudada. RESULTADOS: A distância foi em média 24,48mm ± 0,332mm (esquerdo) e 24,82mm ± 0,316mm (direito). O teste de Anderson-Darling mostrou que as medidas tiveram distribuição normal e a correlação de Pearson's mostrou reprodutibilidade significativa (P < 0,01). O primeiro observador concluiu que 67% das radiografias eram adequadas para avaliar a borda anterior da glenoide, o segundo concluiu que 81% e o terceiro 78% eram satisfatórias para a avaliação. O coeficiente Kappa mostrou que o segundo e terceiro examinadores apresentaram concordância substancial em suas opiniões. CONCLUSÃO: A incidência de Bernageau proporciona uma radiografia adequada para o estudo da borda anterior da glenoide e para o cálculo da sua erosão após a comparação com o lado não acometido.

The purpose of this article is to describe the technique and evaluate the intraoperative and postoperative efficacy of suprascapular nerve block associated with anesthetic infusion into the subacromial space, and compare it with the efficacy of the interscalene block method. Forty-five patients with small or medium isolated lesions of the supraspinatus tendon who underwent arthroscopic repair were prospectively evaluated. Participants were assigned to 3 groups (A, B, and C) of 15 by using restricted randomization by minimization. Group A underwent arthroscopic rotator cuff repair under general anesthesia with interscalene nerve block without using the nerve stimulator device, whereas group B received general anesthesia associated with suprascapular nerve block and anesthetic infusion into the subacromial space before surgery; group C underwent suprascapular nerve block and anesthetic infusion into the subacromial space after surgery. Inhalation anesthetic consumption during surgery was compared among the 3 groups. The postoperative analgesic efficacy of each anesthetic method was measured using the visual analog scale, as well as observing the analgesic drugs consumption. The statistical analysis found no significant differences among patients in the 3 groups in terms of anesthetic consumption during surgery, postoperative analgesic efficacy during the first 48 hours and analgesic drug consumption. The 3 techniques provided similar results in terms of efficacy concerning pain control, anesthetic consumption, analgesic, and antiinflammatory drug consumption, showing that suprascapular nerve block technique with anesthetic infusion into the subacromial space is an excellent alternative to interscalene block, particularly in hospitals where the nerve stimulator device is unavailable.

OBJETIVO: Determinar: 1) se os pacientes que sofrem seu primeiro episódio de luxação traumática do ombro são orientados a manter imobilização por um período mínimo de quatro semanas e qual foi o tipo de imobilização prescrita; 2) determinar após quantos episódios de luxação os pacientes receberam a informação da necessidade de cirurgia; 3) quanto tempo os pacientes demoraram a conseguir acompanhamento com especialista em cirurgia de ombro; 4) quantos episódios de luxação os pacientes apresentavam no momento da cirurgia. MÉTODOS: Dos 100 pacientes tratados cirurgicamente ou estão aguardando cirurgia nos ambulatórios, foram avaliados 61, que responderam a um questionário com perguntas relacionadas com o mecanismo das luxações, locais de atendimento, orientações recebidas para o tratamento do evento agudo e acompanhamento, tempo necessário para conseguir o acompanhamento e cirurgia.Os dados coletados foram submetidos à análise. RESULTADOS: Apenas 13 pacientes (22%) receberam orientações adequadas sobre sua afecção, prognóstico quanto à recidiva e à necessidade de acompanhamento especializado e cirurgia nos casos recidivantes. Nenhum paciente foi orientado adequadamente como e por quanto tempo deveria ficar imobilizado. CONCLUSÃO: Nenhum paciente recebeu orientações de manter-se imobilizado por quatro semanas e o tipo de imobilização variou entre uma tipoia simples e a imobilização comercial tipo Velpeau. A maioria dos pacientes avaliados (78%) não recebeu orientações corretas sobre a necessidade de acompanhamento especializado e cirurgia após o segundo episódio de luxação. O tempo para avaliação do especialista demorou entre quatro e seis meses e possuíam entre um e cem episódios de luxação no momento da cirurgia. OBJECTIVE: To determine: 1) whether the patients had been oriented to use immobilization for at least four weeks and which type of immobilization was prescribed, 2) how many dislocations occurred until the patient received information about the need of surgery, 3) How long it takes for patients to have an appointment with a shoulder surgeon, 4) How many dislocations the patient had at the time of surgery. Material and METHODS: Of the 100 patients surgically treated or waiting for surgery at outpatient facilities, we interviewed 61 patients with questions related to the mechanism of dislocation, emergency service sites, guidelines for acute event treatment and follow-up, time elapsed until surgery and follow-up. Collected data were submitted to analysis. RESULTS: Only 13 patients (22%) had received correct information about their lesion, prognosis concerning recurrence, and about the need of surgery and expert follow-up in recurrent cases. None of our patients received proper information about type and duration of immobilization. CONCLUSION: None of our patients had received proper orientation to remain immobilized for four weeks, and the types of immobilization vary from a handmade sling to a manufactured Velpeau. Most of our patients (78%) did not receive proper orientation about specialized follow-up and surgery after their second episode of dislocation. The time for a specialized appointment with shoulder surgeon ranges from four to six months, with 1-100 dislocation episodes at the moment of surgery.

ABSTRACT For hemiarthroplasty reconstruction of a proximal hu- merus fracture, accurate restoration of humeral head po- sition is challenging, and incorrect prosthetic placement is associated with a poor outcome of surgical treatment. To recreate proper humeral length during the surgery is difficult even when preoperative planning is possible. We now use the pectoral major tendon insertion dis- tance to the top of the humeral head during the procedure to recreate the humeral length by testing positioning of the prosthesis at 5.5 cm from this reference. With this technique, we have been successful in recreating the proper humeral length of the first 11 cases of proximal humerus fracture that we treated with shoulder hemiar- throplasty.

Objective To evaluate the presence of x ray changes in the proximal humerus growth plate of 21 young pitchers. Design Case series. Setting This study was conducted at the Orthopaedic and Traumatology Department of the ABC College of Medicine, Santo Andre, Sao Paulo, Brazil, tertiary institution. Patients 21 male adolescent baseball pitchers, with a mean age of 14.5 years and selected from the Brazilian National Team, were studied. Interventions The patients underwent x ray examinations of the shoulders. Main outcome measurements The x rays of the pitchers’ shoulders were studied to determine any changes in the proximal humeral growth plate and correlate them with clinical findings. Results Fourteen athletes (66%) had radiographic changes in the humerus growth plate but only 5 (36%) had pain complaints. Nine of these 14 cases (64%) whom the observers found radiographic changes did not complain of pain. It was also observed that there was a correlation in only 11 cases between clinical and radiographic evaluations. Conclusion Radiographic changes in the proximal humerus growth plate were found in 66% of the cases, but 64% were asymptomatic. These changes indicate possible evolution, in the future, to a greater degree of retroversion in pitchers’ dominant shoulders.

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

Apresentamos o relato de um caso de lesão da pequena liga no ombro num jovem atleta de 14 anos e do sexo masculino, jogador da seleção Brasileira de Beisebol. Esta lesão é incomum e pouco descrita na literatura. O tratamento realizado foi a suspensão das atividades esportivas por três meses, seguida do retorno gradual aos arremessos. O paciente evoluiu com a resolução do quadro clínico. Here we describe a case report of a small ligament injury in the shoulder of a 14-year-old young male athlete, player of the Brazilian Baseball National team. This kind of injury is uncommon and little described in literature. Treatment provided was the suspension of sport-related activities for three months, followed by a gradual return to throws. The patient evolved to clinical picture resolution.

Purpose To address the factors that surgeons use to decide between 2 options for treatment when the evidence is inconclusive. Methods We tested the null hypothesis that the factors surgeons use do not vary by training, demographics, and practice. A total of 337 surgeons rated the importance of 7 factors when deciding between treatment and following the natural history of the disease and 12 factors when deciding between 2 operative treatments using a 5-point Likert scale between "very important" and "very unimportant." Results According to the percentages of statements rated very important or somewhat important, the most popular factors influencing recommendations when evidence is inconclusive between treatment and following the natural course of the illness were "works in my hands," "familiarity with the treatment," and "what my mentor taught me." The most important factors when evidence shows no difference between 2 surgeries were "fewer complications," "quicker recovery," "burns fewer bridges," "works in my hands" and "familiarity with the procedure." Europeans rated "works in my hands" and "cheapest/most resourceful" of significantly greater importance and "what others are doing," "highest reimbursement," and "shorter procedure" of significantly lower importance than surgeons in the United States. Observers with fewer than 10 years in independent practice rated "what my mentor taught me," "what others are doing" and "highest reimbursement" of significantly lower importance compared to observers with 10 or more years in independent practice. Conclusions Surgeons deciding between 2 treatment options, when the evidence is inconclusive, fall back to factors that relate to their perspective and reflect their culture and circumstances, more so than factors related to the patient's perspective, although this may be different for younger surgeons. Clinical relevance Hand surgeons might benefit from consensus fallback preferences when evidence is inconclusive. It is possible that falling back to personal comfort makes us vulnerable to unhelpful commercial and societal influences.

No. of bitstreams: 0 Previous issue date: 2013-10-22 Background: We aimed to establish values and parameters using multislice reconstruction in axial computerized tomography (CT) in order to quantify the erosion of the glenoid cavity in cases of shoulder instability. Methods. We studied two groups using CT. Group I had normal subjects and Group II had patients with shoulder instability. We measured values of the vertical segment, the superior horizontal, medial and inferior segments, and also calculated the ratio of the horizontal superior and inferior segments of the glenoid cavity in both normal subjects and those with shoulder instability. These variables were recorded during arthroscopy for cases with shoulder instability. Results: The mean values were 40.87 mm, 17.86 mm, 26.50 mm, 22.86 mm and 0.79 for vertical segment, the superior horizontal, medial and inferior segments, and the ratio between horizontal superior and inferior segments of the glenoid cavity respectively, in normal subjects. For subjects with unstable shoulders the mean values were 37.33 mm, 20.83 mm, 23.07 mm and 0.91 respectively. Arthroscopic measurements yielded an inferior segment value of 24.48 mm with a loss of 2.39 mm (17.57%). The ratio between the superior and inferior segments of the glenoid cavity was 0.79. This value can be used as a normative value for evaluating degree of erosion of the anterior border of the glenoid cavity. However, values found using CT should not be used on a comparative basis with values found during arthroscopy. Conclusions: Computerized tomographic measurements of the glenoid cavity yielded reliable values consistent with those in the literature. © 2013 Ikemoto et al.; licensee BioMed Central Ltd.

The purpose of this study was to investigate the prevalence of migraine in medical students, as well as its clinical aspects and impact. All 595 medical students of Santa Casa School of Medicine of São Paulo, Brazil were asked if they had experienced any kind of headache in the past year. Those who responded positively were further investigated by an appropriate questionnaire. Diagnosis of migraine was based on the International Headache Society criteria of 1988. Forty percent of students suffered from some kind of headache; 40.2% of these headaches were migraine. The prevalence of migraine was 54.4% in women and 28.3% in men. Migraine headaches were unilateral in 24.2%, had a gradual onset in 69%, and were of a throbbing type in 88.3%. Migraine was considered incapacitating by 53.9% of students. Migraine with aura caused more disability than migraine without aura. Women experienced more intense migraine than men, and migraine with aura was especially more severe than migraine without aura. Photophobia, phonophobia, and nausea were more commonly encountered in migraine with aura. Despite the high prevalence, the high rate of disability, and the need for analgesic medication, only 7.1% of students with migraine had sought medical treatment.

OBJETIVO: Avaliar os resultados clínico-funcionais das reparações artroscópicas de lesões pequenas e médias do tendão do músculo supraespinal. MÉTODOS: Foram avaliados, retrospectivamente, 129 casos de lesões isoladas pequenas ou médias do tendão do músculo supraespinal. O tempo médio de dor foi de 29 meses. A amplitude articular média era de 136º de elevação ativa, 48º de rotação lateral, rotação medial no nível T12 e a escala funcional pré-operatória da UCLA foi, em média, de 17 pontos. Em todos os casos foi possível o reparo completo da lesão. RESULTADOS: A pontuação pela escala funcional da UCLA no período pós-operatório foi, em média, de 32 pontos. O tempo médio de seguimento foi de 39 meses. Setenta e cinco casos (58%) tiveram resultados excelentes e 42 (32%), bons. A elevação ativa final teve a média de 156º, com ganho médio de 20º, e a rotação lateral final foi, em média, de 57º, com ganho médio de 9º, ambos estatisticamente significativos (P < 0,05). Os pacientes submetidos à tenotomia da cabeça longa do bíceps (CLB), com ou sem tenodese, não apresentaram resultado funcional estatisticamente inferior àqueles que foram submetidos somente à descompressão e reparo da lesão (P = 1,00). Quatorze casos (10,8%) apresentaram complicações no período pós-operatório. Seis casos (4,6%) desenvolveram capsulite adesiva e quatro (3,1%) tiveram rerruptura do tendão comprovada por ressonância magnética. CONCLUSÕES: O reparo artroscópico das lesões pequenas e médias do tendão do músculo supraespinal proporcionou melhora clínico-funcional com bons e excelentes resultados em 90% dos casos. OBJECTIVE: To evaluate the clinical and functional outcomes from arthroscopic repairs on small and medium-sized tears of the supraspinatus muscle tendon. METHODS: 129 cases of isolated small and medium tears of the supraspinatus muscle tendon were evaluated retrospectively. The average duration of pain was 29 months. The average joint range of motion comprised active elevation of 136º, lateral rotation of 58º and medial rotation at T12 level; and the preoperative functional UCLA score averaged 17 points. In all the cases, complete repair could be achieved. RESULTS: The average score on the UCLA functional scale in the postoperative period was 32 points. The average length of follow-up was 39 months. Seventy-five cases (58%) had excellent results and 42 (32%) had good results. The average final active elevation was 156º with an average gain of 20º, and the average final lateral rotation was 57º with an average gain of 9º. Both of these were statistically significant (P < 0.05). The patients who underwent tenotomy of the long head of the biceps (LHB), with or without tenodesis, did not present statistically inferior functional outcomes, in comparison with the patients who only underwent decompression and lesion repair (P = 1.00). Fourteen cases (10.8%) presented complications during the postoperative period. Six (4.6%) developed adhesive capsulitis and four (3.1%) presented re-rupture of the tendon, proven by means of magnetic resonance imaging. CONCLUSIONS: Arthroscopic repair of small and medium tears of the supraspinatus muscle tendon provided a functional clinical improvement, with good and excellent results in 90% of the cases.

OBJETIVO: Descrever a experiência inicial de quatro serviços ortopédicos com a artroplastia total do cotovelo (ATC) Bi-Contact® relatando os resultados e complicações do procedimento. MÉTODOS: Estudo retrospectivo, através da análise de prontuários, de pacientes submetidos à ATC primária com modelo de prótese desenvolvido junto ao IOT-HCFMUSP. Foram avaliados 46 cotovelos (45 pacientes) operados de 2000 a 2009 em quatro serviços ortopédicos. RESULTADOS: A maioria dos pacientes era do sexo feminino (74%) e a mediana da idade foi de 62,5 anos. Os diagnósticos encontrados foram sequela de trauma (47,83%), artrite reumatóide (32,61%), osteoartrose primária (8,7%), fraturas agudas (6,52%) e ossificação heterotópica (2,17%). A mediana do tempo de acompanhamento foi de 2,08 anos (0,25-9). O procedimento melhorou significativamente a dor e o arco de movimento. Foi evidenciada a presença de pelo menos uma complicação em 69,57% dos casos, sendo as principais infecção (28,26%), necessidade de revisão (28,26%), fratura intraoperatória (15,22%) e soltura asséptica (15,22%). CONCLUSÃO: A ATC do tipo Bi-Contact® propiciou uma melhora significativa na dor e no arco de movimento na presente série. O índice de complicação é alto, sendo as mais frequentes infecção, soltura asséptica e fratura intraoperatória. OBJECTIVE: To describe the initial experience of four orthopedic clinics from using Bi-Contact® total elbow arthroplasty (TEA), reporting the results and complications of the procedure. METHODS: This was a retrospective study, through analysis on the medical records of patients who underwent primary TEA using a prosthesis model developed in conjunction with IOT-HCFMUSP. Forty-six elbows (45 patients) that were operated at four orthopedic clinics between 2000 and 2009 were evaluated. RESULTS: The majority of the patients were female (74%), and the median age was 62.5 years. The diagnoses encountered were trauma sequelae (47.83%), rheumatoid arthritis (32.61%), primary osteoarthrosis (8.7%), acute fractures (6.52%) and heterotopic ossification (2.17%). The median length of follow-up was 2.08 years (0.25-9). The procedure significantly alleviated pain and improved range of motion. It was observed that at least one complication was present in 69.57% of the cases, and the main ones were infection (28.26%), need for revision (28.26%), intraoperative fracture (15.22%) and aseptic loosening (15.22%). CONCLUSION: Bi-Contact® TEA provided significant alleviation of pain and improvement of range of motion in the present series. The complication rate was high, and the most frequently observed complications were infection, aseptic loosening and intraoperative fracture.
