Purpose: In 47 consecutive patients who had a shoulder impingement syndrome treated by arthroscopic subacromial decompression, we compared the functional outcome with the amount of the acromion resection.
Type Of Study: Prospective study.
Methods: The inclusion criteria for patient selection was a chronic impingement syndrome unresolved by conservative treatment with an intact rotator cuff or with an irreparable rupture of the rotator cuff.
Study Design: Posterior implants were used to test the resistance of seven human thoracic spines to traction, and results were compared with those of a digital study.
Objectives: To compare the use of hook and screw fixation methods for posterior thoracic surgery in a study supplemented by a digital analysis using the finite-element method.
Summary Of Background Data: The maximum break strength of pedicular screws on bone has already been studied several times.

Purpose Of The Study: This retrospective work was conducted to analyze the quality of the bone-implant interface at mid-term in 45 cases treated with a non-cemented Miller-Galante 1 total knee arthroplasty.
Material And Methods: All the protheses reviewed were implanted without cement. A patellar implant was cemented in 31.
Subacromial impingement: influence of coracoacromial arch geometry on shoulder function.

Objective: To find correlations between radiological coracoacromial arch geometry and shoulder function in patients with subacromial impingement syndrome.
Patients And Methods: During a prospective study of the efficacy of arthroscopic subacromial decompression, we evaluated the function of the treated and contralateral shoulders using Constant's functional score and confronted the results to several radiographic parameters reflecting coracoacromial arch geometry.
Results: Constant's score values were low (42 +/- 15) because of pain and a low level of activity.
