RESUMOObjetivo: Avaliar a concordância interobservador de três classificações utilizadas para a fratura do platô tibial: Schatzker, Grupo AO e Hohl. Método: Nove observadores, subdivididos de acordo com o grau de titulação (seis médicos residentes -MR -e três médicos especialistas -ME), classificaram 50 fraturas do platô tibial. A concordância interobservador foi avaliada pelo coeficiente Kappa. Resultados: Comparando-se os médicos residentes (MR) com os médicos especialistas (ME), observou-se que as três classificações apresentaram concordância de grau fraco e moderado. Entre os MR, as classificações do Grupo AO e de Hohl mostraram relação direta entre aumento no grau de concordância e ano de residência médica, o que foi observado de forma parcial para a classificação de Schatzker. Para a classificação de Hohl, o Kappa variou de 0,344 a 0,577; para a classificação do Grupo AO, variou de 0,36 a 0,499; e para a classificação de Schatzker, variou de 0,278 a 0,465. Conclusão: Existe concordância significativa, ao nível de 1%, entre as três classificações para todos os pares de observadores. Comparando-se os MR com os ME, as três classificações estudadas apresentam concordância de grau fraco e moderado. A classificação de Hohl apresenta a maior concordância entre os MR. Descritores - INTRODUçãOAs fraturas do platô tibial representam 1 a 2% de todas as fraturas e aproximadamente 8% das fraturas em idosos (1) . Por se tratar de fraturas que envolvem a cartilagem articular, necessitam de redução anatômica e mobilidade precoce, que são preferencialmente obtidas por meio cirúrgico (2) . Nesse sentido, a utilização de um sistema de classificação abrangente torna mais compreensível a definição da tática e do acesso cirúrgicos.De forma conceitual, a proposta da adoção de um sistema de classificação passa por sua capacidade de reprodutibilidade, simplicidade e facilidade de memorização, aju-

The osteoid osteoma is a bone tumor that accounts for 10% of benign tumors. It was described in 1935 by Jaffe, as a tumor that affects the young adult population, with a predominance of males. This study aims to present a case of late diagnosis of a patient with osteoid osteoma of the distal clavicle region. Female patient, 44 years old, non-professional volleyball player, reported pain in the anterior and superior region of the shoulder girdle, specifically in the acromioclavicular joint, which worsened at night and had been treated for nine months as tendinitis of the rotator cuff and acromioclavicular joint arthritis. After confirming the diagnosis, the patient underwent open surgery with resection of the distal clavicle. At two years of follow-up, the patient presents without local pain. In the radiographic evaluation, coracoclavicular distance is preserved and there are no signs of recurrence. Tumors of the shoulder girdle are rare and are often diagnosed late. A high degree of suspicion for the diagnosis of tumors of the shoulder girdle is needed in order to avoid late diagnosis.

Superior capsule reconstruction is a valuable intervention for some patients who present symptomatic irreparable posterosuperior rotator cuff tears. Superior capsule reconstruction techniques most commonly use either fascia lata autograft or dermal allograft. Both options have literature support but also present a few drawbacks such as donor site issues, potential allergic reactions, and high cost of the operation. The long head of biceps is a potential graft for rotator cuff tears and may be particularly useful in bridging the gap in irreparable massive rotator cuff tears, specifically as an alternative to more traditional superior capsular reconstruction. Long head of biceps transposition may offer unique and significant advantages over other techniques and can be an effective and valuable alternative in selected cases. The tendon’s insertion into the glenoid is left intact, whereas laterally it is transferred to a more central humeral head position and sutured with anchors onto the footprint of the supraspinatus tendon acting as a superior static stabilizer of the shoulder joint. The purpose of this article is to propose a technical modification of superior capsular reconstruction using long head of the biceps tendon autograft.

Objective: To assess the inter-observer agreement of three tibial plateau fracture classifications: Schatzker, AO Group, and Hohl. Methods: Nine physicians of different levels of expertise (six Orthopaedic Residents – OR – and three Orthopaedic Attendings – OA) classified 50 tibial plateau fractures. Results: There was a low to moderate agreement between OR and OA on the three classification systems. A straight correlation was found between the year of Residence and an increase on the level of agreement on the AO group and Hohl classifications. This was partially seen on the Schatzker classification. Kappa ranged from 0.344 to 0.577, 0.36 to 0.499, and 0.278 to 0.465 for the Hohl, AO group, and Schatzker systems, respectively. Conclusion: With a level of 0.1, there was a significant agreement on the three classifications among the physicians. When comparing ORs to OAs, the three studied classifications show low to moderate consistency, with the Hohl classification showing the highest level of agreement between OR.
