A better understanding of the morphology underneath the acromion is needed to prevent complications after arthroscopic subacromial decompression. The precise correlations between the morphologic features underneath the acromion and the surrounding structures including the attachment of the coracoacromial ligament (CAL) and the origin of the deltoid middle head have not yet been determined in the absence of artifacts on the bony surface caused by dissection techniques. Moreover, anatomic findings in previous studies using only older-aged cadavers or dried bones may not reflect the morphologic features of younger and healthy specimens.

To characterize the anterolateral structures morphologically in the inferior aspect of the acromion, assess the relationships of these structures with surrounding structures without dissection artifacts on the bony surface, and verify the cadaveric data in the asymptomatic shoulders of living middle-aged patients.

Descriptive laboratory study.

We initially analyzed the reatients revealed bony prominences similar to those observed in cadavers.

The anterolateral prominence, which corresponds to the attachment of the CAL below the acromion, may be a native structure below the acromion. 5′-Ethylcarboxamidoadenosine Moreover, the CAL is continuous to the deep layer of the deltoid middle head in the lateral acromion.

The literature on upper extremity injuries in professional soccer players is scarce, and further insight into the onset and cause of these injuries as well as potential differences between goalkeepers and outfield players is important.

To investigate the epidemiology of hand, wrist, and forearm injuries in male professional soccer players between 2001 and 2019.

Descriptive epidemiology study.

Between the 2001-2002 and 2018-2019 seasons, 120 European male soccer teams were followed prospectively for a varying number of seasons (558 team-seasons in total). Time-loss injuries and player-exposures to training sessions and matches were recorded on an individual basis in 6754 unique players. Injury incidence was reported as the number of injuries per 1000 player-hours, and between-group differences were analyzed using

statistics and rate ratios (RRs) with 95% CIs. Between-group differences in layoff time were analyzed.

In total, 25,462 injuries were recorded, with 238 (0.9%) of these affecting the handst, and forearm constituted less than 1% of all time-loss injuries in male professional soccer players. Fractures were most common and constituted more than half of all injuries. Goalkeepers had a 7-fold higher incidence and an over 1-week longer mean layoff time compared with outfield players.

Posterior shoulder instability is uncommon, and its treatment is a challenging problem. An arthroscopically assisted technique for posterior iliac crest bone grafting (ICBG) has shown promising short- and long-term clinical results. Changes as shown on imaging scans after posterior ICBG for posterior shoulder instability have not been investigated in the recent literature.

To evaluate changes on computed tomography (CT) after arthroscopically assisted posterior ICBG and to assess clinical outcomes.

Case series; Level of evidence, 4.

Patients with preoperative CT scans and at least 2 postoperative CT scans with a minimum follow-up of 2 years were included in the evaluation. Of 49 initial patients, 17 (follow-up rate, 35%) met the inclusion criteria and were available for follow-up. We measured the glenoid version angle and the glenohumeral and scapulohumeral indices on the preoperative CT scans and compared them with measurements on the postoperative CT scans. Postoperatively, graft surface, resorptioncome scores were improved. Osteoarthritis progression in almost 50% of patients is concerning for the long-term success of this procedure.

Arthroscopically assisted posterior ICBG restored reliable parameters as shown on CT scans, especially glenoid version and the posterior subluxation indices. Graft resorption was common and could be observed in all shoulders. Patient-reported clinical outcome scores were improved. Osteoarthritis progression in almost 50% of patients is concerning for the long-term success of this procedure.

In the presence of medial meniscus posterior root tear (MMPRT), there is a possibility of reduced compression of meniscal tissue in hyperflexion as the intra-articular mobility of the meniscus increases. This phenomenon can be mimicked during clinical examination.

To describe, evaluate, and validate the diagnostic performance of a new clinical indicator, the Akmese sign, for the diagnosis of an MMPRT.

Cohort study (diagnosis); Level of evidence, 2.

In this study, we prospectively enrolled patients aged 18 to 55 years who were scheduled for arthroscopic surgery after a diagnosis of medial meniscal lesion at a single institution between January 2016 and January 2018. All of the patients underwent preoperative examination for the Akmese sign. All surgeries were performed by a single surgeon with more than 5 years of experience in sports injury surgery, who was blinded to the Akmese sign results.

A total of 273 patients with a mean age of 42.4 ± 5.3 years met the study criteria. The Akmese sign was identified as positive in 33 patients, and MMPRT was confirmed during arthroscopy in 36 cases. The performance parameters of the Akmese sign were a sensitivity of 86.1%, specificity of 99.1%, Youden index of 0.85, and kappa index of 0.88.

This study showed that the Akmese sign is a useful new physical examination test that can help clinicians distinguish MMPRTs from other meniscal medial meniscal pathology.
