Anatomic and CT scan assessment of Teres Minor: a new index of trophicity.

Introduction: The present study reports the development of a CT assessment protocol for Teres Minor (TM) trophicity.

Hypothesis: Quantitative reproductible Terres Minor assessment on CT estimates the influence of muscle trophicity on the clinical and radiological results of palliative treatment of irreparable rotator cuff tear.

Materials And Method: An anatomic study of 30 cadaveric shoulders confirmed a constant anatomic relation between Terres Minor and the inferior pole of the glenoid cavity.

Reproducibility and reliability of subscapularis tendon assessment using CT-arthrography.

Background: Computed tomography (CT) coupled with arthrography remains the reference standard for the preoperative evaluation of rotator cuff tears. The objectives of this study were to evaluate intra-observer and inter-observer reproducibilities of CT-arthrographic assessment of the subscapularis tendon and to assess the validity and reliability of this investigation.

Hypothesis: CT-arthrography is reliable and reproducible for the preoperative characterisation of subscapularis tendon lesions.

Geometrical analysis results of 42 resurfacing shoulder prostheses: A CT scan study.

Background: Shoulder resurfacing arthroplasty was introduced in Scandinavia in the early 1980s then developed by SA Copeland.

Hypothesis: Resurfacing prostheses restore the normal anatomy of the proximal humerus. Here, our objective was to evaluate humeral resurfacing prosthesis position on radiographs and computed tomography (CT) images.

Sandwich type ceramic liner fracture rate with the Atlas III™ socket: A study of 144 primary total hip replacements at a mean 74 months' follow-up.

Introduction: Ceramic friction bearings have been proposed as a means of reducing wear in total hip replacement (THR). A "sandwich" composite concept including a ceramic bearing surface has been proposed as simplifying the modularity while matching metal-back cups with a polyethylene liner. It is not precisely known how frequently abnormal noise would occur during functioning of this type of implant, which moreover entails a risk of ceramic liner fracture.
