Traumatic sternoclavicular dislocation is a rare injury corresponding to less than 5% of all injuries of the scapular belt. It is preferentially treated through reduction of the sternoclavicular joint, symptom relief, a brief period of immobilization and rehabilitation, with the aim of gaining strength and range of motion. In some patients, however, this type of injury may progress with instability and pain, thus causing discomfort and pain. On such occasions, surgical treatment is chosen. The objective of this study was to report the clinical case of a sports player who progressed with chronic traumatic anterior instability of the sternoclavicular joint and underwent reconstruction using the ipsilateral semitendinosus tendon. This was a 16-year-old male patient who was a state-level judo player. Following a fall during a fight, he presented pain, slight deformity and edema in the right sternoclavicular joint, and he underwent conservative treatment for 12 months, without success. In the end, reconstruction of the sternoclavicular joint was carried out using the ipsilateral autologous semitendinosus, with resection of the intra-articular disc and suturing of the costoclavicular ligaments. We have presented a case of dislocation of the sternoclavicular joint in a high-performance judo player who underwent reconstruction using the semitendinosus, with excellent functional results after 1 year of follow-up.

Objective: To analyze the results of 159 patients with anterior instability of the shoulder

A grande maioria das fraturas de diáfise de úmero são de tratamento conservador. As indicações absolutas(ie lesão vascular) e relativas(ie paralisia nervosa primária) para tratamento cirúrgico estão bem estabelecidas na literatura. Os dois principais métodos utilizados para tal, a placa de auto-compressão e a haste intramedular travada possuem estudos comparando-os.No entanto não existem trabalhos comparando a haste intramedular com a placa em ponte e é a este fim que o presente estudo destina-se.

Although the biomechanical importance of the subscapularis tendon has been recognized in biomechanical 1 and clinical studies, 2 it has long received little attention in the medical literature, 3 and has been called the "forgotten tendon". 4 Only 1% of rotator cuff tears affect only the subscapularis, 5,6 but more than half of all patients with supraspinatus tears present an associated tear of this tendon. 7,8 The accuracy of magnetic resonance imaging (MRI) is usually lower for detection of subscapularis tears than for rotator cuff tears overall, 9,10 with sensitivity ranging from 25% to 94% 5,11 and specificity from 67% to 100%. [12][13][14] Studies evaluating the diagnosis of subscapularis tears are important for clinical practice, with implications for prognosis and surgical planning. Among the published studies, some have included low magnetic field MRI, 7,13,15,16 small samples, 15,17 diagnosis not restricted to rotator cuff disorders, 7,12,14-16,18-21 and use of intra-articular 11,14,19 or intravenous 15,20 contrast. These factors can generate bias in data interpretation. OBJECTIVEThe objective of the present study was to evaluate the accuracy of preoperative high magnetic field MRI without the use of contrast, compared with arthroscopic inspection, for identifying subscapularis tears, in cases undergoing rotator cuff repair. METHODSThis was a diagnostic test study comparing the findings from preoperative MRI (index test) with those from shoulder arthroscopy (reference standard) for diagnosing subscapularis tears.Operative data were collected in a standardized manner from consecutive patients between January 2013 and August 2017, by three surgeons at the same institution.

Rotator cuff rupture is a common affection causing an impact on the daily lives of patients, resulting in functional disability and pain. A reasonable number of patients need tendinous repair. Current trends on shoulder surgery are the use of minimally invasive techniques with lower per-operative morbidity and earlier rehabilitation. From the 1990's on, shoulder arthroscopy was largely developed, as well as the use of anchors for tendinous sutures fixation. This technical evolution has allowed for arthroscopic surgery outcomes comparable to those in open surgeries. One of the potential problems for the use of anchors in shoulder arthroscopic surgeries is related to its loosening from bone surface. The present study has as an objective to compare the tensile strength of threaded metal anchors inserted on cortical and spongy bones.
