OBJECTIVE To establish the anatomical relationship of the suprascapular nerve (SSN) located in the suprascapular notch, to the medial border of the base of the coracoid process, the acromial joint surface of the acromioclavicular joint and the anterolateral border of the acromion. METHODS We dissected 16 shoulders of 16 cadavers (9 males and 7 females). The distances from the suprascapular ne...

<p>Fracture of the acromion process is an uncommon injury. The most common mechanism injury direct trauma to acromion. Isolated fractures are rare as usually they associated with concomitant skeletal and soft tissue injuries shoulder. We present a case 45-year-old male type 3 fracture reduction subacromial space. Patient was managed surgically fixed using tension band wiring. followed up ...

The validation of two noninvasive methods for measuring the dynamic three-dimensional kinematics of the human scapula with a magnetic tracking device is presented. One method consists of simply fixing a sensor directly to the acromion and the other consists of mounting a sensor to an adjustable plastic jig that fits over the scapular spine and acromion. The concurrent validity of both methods w...

Subacromial impingement is typically diagnosed in the older throwing athlete who has a stable shoulder. Often these overhand athletes will have a loss of internal rotation that may be refractory to stretching. Some have postulated bony adaptive changes in the thrower leading to internal rotation loss.1,2 These patients have a painful arc, positive impingement maneuvers, and respond affirmativel...

The shoulder girdle of turtles has a triradiate morphology. Although its dorsal process represents the scapular blade, the skeletal identities of the two ventral processes remain uncertain. To elucidate the question, developmental patterns of the girdles were compared between Chinese soft-shelled turtles, chickens, and mice. Despite the morphological diversity of adults, the initial primordia o...

BACKGROUND The posterior and anterior circumflex humeral artery (PCHA and ACHA) are crucial for the blood supply of humeral head. We aimed to identify simple landmarks for guiding the quick access to PCHA and ACHA, which might help to protect the arteries during the surgical management of proximal humeral fractures. METHODS Twenty fresh cadavers were dissected to measure the distances from th...

OBJECTIVE : To describe the surgical technique and preliminary clinical outcomes in a series of open reduction internal fixation of basal acromion process fractures applying a double-plating technique. METHODS : Nine consecutive patients, mean age 33.4 years old (range, 23-61 years old) with unilateral acromion fracture (Type 3 AO/OTA) with more than 1cm displacement who underwent fixation ut...

To investigate measures describing scapular anatomy with long-term follow-up related to development of rotator cuff disease or glenohumeral arthritis. A second aim was if the critical shoulder angle (CSA) and acromion index (AI) changed over time compare contralateral at follow-up.

Pain and impaired function in the shoulder can result from a variety of conditions. Dysplasias of the shoulder girdle are usually asymptomatic; previous literature reports on shoulder malformation have focused on glenoid dysplasia or complete agenesis of the clavicle. We report the case of an 11 year old patient with severe shoulder pain after strenuous physical exercise. Physical inspection sh...

Magnetic resonance imaging makes it possible to inspect the status of the rotator cuff and the shape of the acromion. To clarify the relationship between acromial shapes and rotator cuff tears, we evaluated magnetic resonance images obtained in 192 shoulders. We classified the acromial shapes into 3 types: type I (flat), type II (curved), and type III (hooked). Among a group of 91 shoulders wit...
