The serratus anterior is portrayed as a homogeneous muscle in textbooks and during functional activities and rehabilitation exercises. It is unclear whether the serratus anterior is composed of subdivisions with distinctive morphology and functions. The purpose of this study was to determine whether the serratus anterior could be subdivided into different structural parts on the basis of its segmental architectural parameters. Eight formalin-embalmed serratus anterior muscles were dissected and the attachments of each fascicle documented...

OBJECTIVE: To define the radiographic origin and insertion of the canine medial glenohumeral ligament (MGHL) at the scapula and the humerus of dogs as radiographic aim points for the surgical ligament reconstruction. MATERIAL AND METHODS: The forelimbs (n = 20) from 10 adult, orthopaedically unaffected dogs (> 20 kg body weight) were used. Radiopaque markers (1 mm steel bullet) were placed into the visual origin and insertion of the MGHL. Finally, virtual digital radiographs were produced in medio-lateral and cranio-caudal projection and the location of the origin and insertion points were expressed using four different methods (4x4 grid box method, percentage position in the grid box for the medio-lateral projection, the percentage position orientated at different landmarks and the clock-face scale method)...

PURPOSES: It has been reported that the amount of posterior tilt and upward rotation in scapular motions decreases with aging. The purposes of the current study were to investigate age related scapular motion regression and scapular restriction in patients with idiopathic frozen shoulder (IFS). METHODS: The groups were recruited as follows: two groups of 50 asymptomatic subjects aged in their twenties and fifties, and 56 patients with IFS. We passively moved the scapula toward 8 directions: elevation/depression; upward/downward rotation; external/internal rotation; and anterior/posterior tilt...

PURPOSE: To propose and to assess the reproducibility of a new method (GO [glenoid orientation] index) for the estimation of the glenoid orientation in relation to the anterior surface of the glenoid. METHODS: This is a retrospective study on computed tomography (CT) scan. The GO index was defined as the angle formed by a line perpendicular to the tangent to the anterior surface of the scapula and the glenoid line (which is defined as the line connecting the anterior and the posterior rim of the glenoid)...

OBJECTIVES: Postlaparoscopic shoulder pain (PLSP) remains a common problem after laparoscopies. The aim of this study was to investigate the correlation between pressure pain threshold (PPT) of different muscles and PLSP after gynecologic laparoscopy, and to explore the effect of parecoxib, a cyclooxygenase-2 inhibitor, on the changes of PPT. MATERIALS AND METHODS: The patients were randomly allocated into two groups; group P and group C. In group P, parecoxib 40 mg was intravenously infused at 30 minutes before surgery and 8 and 20 hours after surgery...

OBJECTIVE: Scapular motion is essential for full, functional mobility of the arm. Many shoulder pathologies are associated with alterations of scapular kinematics which have been only little studied in total shoulder arthroplasties. The aim of this study was to compare the 3D scapula kinematics in two groups of patients with total shoulder anatomic (aTSA) or reverse (rTSA) arthoplasties to asymptomatic controls of comparable age during two arm elevation tasks (abduction and flexion) and two simulations of activity of daily living ("hair combing" and "back washing")...

OBJECTIVE: Winging of the scapula has a variety of causes and a variable prognosis. It contributes to a disruption of the scapulohumeral rhythm with a decreased flexion and abduction of the upper extremity and a source of a considerable pain. This condition can affect the ability to perform activities of daily living. The most common cause of scapula winging is serratus anterior paralysis resulting from a lesion of the long thoracic nerve. The rupture of the muscle itself remains uncommon...

OBJECTIVE: The Western Ontario Shoulder Instability Index (WOSI) is a specific self-questionnaire which measures the functional impact during patients' everyday life activities in order to evaluate the therapeutic care face to a chronic scapula-humeral instability. In his original version in English, it is valid, reliable and sensible to change. The goal of this study is to translate and culturally adapt the original algo-functional score WOSI in French and to evaluate metrological quality of this version with patients suffering of chronic instability after scapula-humeral luxation...

BACKGROUND: The most commonly recommended initial treatment for multidirectional instability is a rehabilitation program. Although there is evidence to support the effect of conservative management on this condition, the published literature provides little information on the exercise parameters of such programs. In addition, current published rehabilitation programs for multidirectional instability do not focus on scapula stability or exercise drills into functional and sports-specific positions, which are often important aspects to consider in this patient population...

Posterior shoulder tightness (PST) and glenohumeral internal rotation deficit (GIRD) are common physical impairments in overhead sports, such as baseball, cricket and tennis.(1-4)) PST is clinically measured by passive shoulder horizontal adduction with scapula stabilized in supine or side lying.(5),(6)) GIRD is generally characterised as concurrent deficits of internal rotation (IR) and total arc of motion in dominant side.(7),(8)) Although the mechanisms of PST and GIRD are not clear, it is speculated that they derive from tight posterior glenohumeral capsule and posterior muscles, such as posterior deltoid, infraspinatus and teres minor muscles...

CONTEXT: Compromise to the acromio-humeral distance has been reported in subjects with subacromial impingement syndrome when compared to healthy subjects. In clinical practice patients are taped with the intention of altering scapular position and influencing the acromio-humeral distance. However, research to determine the effects of taping on acromio-humeral distance is exiguous. OBJECTIVES: To evaluate the effect of ridged taping techniques to increase posterior scapular tilt and upward scapular rotation on the acromio-humeral distance...

BACKGROUND: Glenoid retroversion may accelerate glenoid loosening after total shoulder arthroplasty. Accurate measurement of preoperative glenoid deformity is critical for decision-making and prognostication. The purpose of this study was to determine whether glenoid version, inclination, and depth and humeral subluxation measurements on computed tomography (CT) scan slices oriented in the plane of the body differ from those oriented in the scapular plane and those obtained by automated 3-dimensional reconstruction software in the setting of a biconcave B2-type glenoid...

BACKGROUND: For shoulder arthroscopy, few anatomical landmarks are available and inexperienced surgeons tend to be adrift due to the limited visual field of the scope. The purpose of this study was to demonstrate the useful landmarks around the glenoid for accurate orientation, and also the safe distance to avoid suprascapular nerve injury during surgical procedures around the glenoid. METHODS: In 15 human solution-fixed cadavers, a cross-section of the shoulder joint on the labrum surface was created...
