OBJECTIVE The purpose of this study was to determine whether occult bony injuries or other characteristic MR abnormalities are frequent in patients suspected of having traumatic tears of the rotator cuff. SUBJECTS AND METHODS MR arthrography of the shoulder was performed in 24 consecutive patients with suspected traumatic tears of the rotator cuff. MR findings were analyzed with regard to abn...

OBJECTIVES To calculate the difference between the desired tibial tuberosity advancement (TTA) along the tibial plateau axis and the advancement truly achieved in that direction when cage size has been determined using the method of Montavon and colleagues. To measure the effect of this difference on the final patellar tendon-tibial plateau angle (PTA) in relation to the ideal 90°. METHODS Tr...

simultaneous dislocation of shoulder and humeral shaft fracture is a rare injury, and there is no clear protocol for its treatment. herein we present a case of a 15-year-old boy, who suffered from a job-related accident and sustained fracture of humeral shaft associated with ipsilateral anterior shoulder dislocation and fracture of greater tuberosity 15 years ago. he received closed reduction o...

Although various implants exist for 3- and 4-part fractures, few implants are appropriate for isolated greater tuberosity fractures. This retrospective study evaluated the efficacy of AO X-shaped midfoot locking plates for greater tuberosity fractures. Between May 2008 and September 2009, nineteen patients with displaced greater tuberosity fractures were treated with open reduction and internal...

Nine fresh-frozen, human cadaveric shoulders were elevated in the scapular plane in two different humeral rotations by applying forces along action lines of rotator cuff and deltoid muscles. Stereophotogrammetry determined possible regions of subacromial contact using a proximity criterion; radiographs measured acromiohumeral interval and position of greater tuberosity. Contact starts at the an...
