Anatomical Total Shoulder Arthroplasty with Keeled glenoids in Patients under 60 years at 10 years minimum: which risk factors of failure are still valid at long term follow-up?

Aim: To assess the long-term (>10 years) outcomes in anatomical total shoulder arthroplasty (aTSA) and implant survival in patient under 60 years and identify risk factors for complications and revision.

Methods: This was a retrospective, multicenter study conducted from 1993 to 2008. Over 104 aTSA, 87 in 82 patients (55 years, 36 to 60yo) were included at a mean follow-up of 14±4 years (10 to 25y).

Posterior shoulder instability.

Posterior shoulder instability (PSI) is defined by dynamic, recurrent and symptomatic partial or total loss of posterior joint contact. Anatomic risk factors comprise ligament hyperlaxity, glenoid retroversion or dysplasia, and high horizontal acromial morphology. Associated anatomic lesions comprise labrum lesions, posterior glenoid erosion and/or fracture, and anterior humeral head notching.

Spotlight on Carcinosarcoma of the Ovary: A Scoping Review.

Ovarian carcinosarcoma, also referred as malignant mixed Mullerian tumour, is an uncommon, highly aggressive and malignant neoplasm which makes up 1 to 4% of all ovarian tumours. It is biphasic involving both malignant sarcomatous (mesenchymal) and carcinomatous (epithelial) cells. There are various subtypes such as serous and endometrioid.

The effect of humeral tray thickness on glenohumeral loads in a reverse shoulder 'smart' implant.

Purpose: The aim of this study was to observe the effects of changing humeral tray thickness on the resultant of intraoperative glenohumeral joint loads using a load-sensing system (LSS).

Methods: An rTSA was performed on fresh frozen full-body cadaver shoulders by using an internal proprietary LSS on the humeral side. The glenohumeral loads (Newtons) and the direction of the resultant force applied on the implant were recorded during four standard positions (External rotation, Extension, Abduction, Flexion) and three "complex" positions of Activity Daily Life ("behind back", "overhead reach" and "across chest").

Epileptic patients with anterior shoulder instability: are there specific bone lesions? A case control study.

Hypothesis: Chronic epilepsy may cause important bipolar bony lesions. We aim to compare the specific pathoanatomic metrics of the bony lesions in chronic shoulder anterior instability that occur in patients with epilepsy vs. patients without epilepsy.
