  • Scapular Dyskinesis
    Scapular Dyskinesis Presented by: Scott Sevinsky MSPT Presented by: Scott Sevinsky SPT 1 What is Scapular Dyskinesis? Alteration in the normal static or dynamic position or motion of the scapula during coupled scapulohumeral movements. Other names given to this catch-all phrase include: “floating scapula” and “lateral scapular slide”.1, 2 1 Alterations in scapular position and motion occur in 68 – 100% of patients with shoulder injuries. Scapular Dyskinesis Classification System 1, 3 Pattern Definitions Inferior angle At rest, the inferior medial scapular border may be prominent dorsally. During arm motion, the inferior (type I) angle tilts dorsally and the acromion tilts ventrally over the top of the thorax. The axis of the rotation is in the horizontal plane. Medial border At rest, the entire medial border may be prominent dorsally. During arm motion, the medial scapular (type II) border tilts dorsally off the thorax. The axis of the rotation is vertical in the frontal plane. Superior border At rest, the superior border of the scapula may be elevated and the scapula can also be anteriorly (type III) displaced. During arm motion, a shoulder shrug initiates movement without significant winging of the scapula occurring. The axis of this motion occurs in the sagittal plane. Symmetric At rest, the position of both scapula are relatively symmetrical, taking into account that the dominant scapulohumeral arm may be slightly lower. During arm motion, the scapulae rotate symmetrically upward such that the (type IV) inferior angles translate laterally away from the midline and the scapular medial border remains flush against the thoracic wall. The reverse occurs during lowering of the arm.

Biceps tendonitis, also called bicipital tendon- It also blends with the cartilage rim around itis, is inflammation in the main tendon the glenoid, the labrum. The labrum is a rim that attaches the top of the biceps muscle of soft tissue that turns the flat surface of the to the shoulder. The most common cause is glenoid into a deeper socket. This arrange- overuse from certain types of work or sports ment improves the fit of the ball that fits in the activities. Biceps tendonitis may develop socket, the humeral head. gradually from the effects of wear and tear, or it can happen suddenly from a direct injury. The tendon may also become inflamed in response to other problems in the shoulder, such as rotator cuff tears, impingement, or instability (described below). This guide will help you understand • what parts of the shoulder are affected • the causes of a biceps tendonitis • ways to treat this problem Beginning at the top of the glenoid, the tendon Anatomy of the long head of the biceps runs in front of What parts of the shoulder are affected? the humeral head. The tendon passes within The biceps muscle goes from the shoulder to the elbow on the front of the upper arm. Two separate tendons (tendons attach muscles to bones) connect the upper part of the biceps muscle to the shoulder. The upper two tendons of the biceps are called the proximal biceps tendons, because they are closer to the top of the arm.

Review of Superficial Veins in Arm The cephalic and basilic veins are the main superficial veins of the upper limb. They originate from the dorsal venous network on the dorsum of the hand. • The cephalic vein ascends along the anterolateral aspect of the forearm and arm. It then follows the superior border of the pectoralis major muscle to enter the deltopectoral triangle. It ultimately joins the axillary vein after passing through the clavipectoral fascia. • The basilic vein ascends along the medial forearm and the arm. In the arm, it passes deep to the brachial fascia where it courses in close proximity to the brachial artery and medial cutaneous nerve of the forearm along its path into the axilla.

  • MORPHOMETRIC ANALYSIS of BICIPITAL GROOVE of UPPER END of HUMERUS in SOUTH INDIAN POPULATION Ashwini

ISSN 2321-4287 Original Research Article DOI: https://dx.doi.org/10.16965/ijar.2017.209 MORPHOMETRIC ANALYSIS OF BICIPITAL GROOVE OF UPPER END OF HUMERUS IN SOUTH INDIAN POPULATION Ashwini. N.S *1, Venkateshu.K.V 2. *1 Assistant Professor, Department Of Anatomy, Sri Devaraj Urs Medical College, Tamaka, Kolar, Karnataka, India. 2 Professor And Head, Department Of Anatomy, Sri Devaraj Urs Medical College, Tamaka, Kolar, Karnataka, India. ABSTRACT Introduction: The Bicipital Groove (BG) or intertubercular groove in the upper end of the humerus is a deep groove formed between the greater and lesser tubercles. This groove lodges the long tendon of the Biceps brachii and also transmits a branch of the anterior humeral circumflex artery. Its lips are called as the crests of the greater and lesser tubercles (bicipital ridges), and form the upper parts of the anterior and medial borders of the body of the bone. Materials and Methods The study was carried out in 87 adult humeri (39 right and 48 left sides) from the Department of Anatomy, Sri Devaraj Urs Medical college, Tamaka, Kolar, Karnataka. Damaged or bones with deformities were excluded from the study. The length, width, depth were accurately measured using digital vernier callipers.The medial wall angle(MWA) and lateral wall angle(LWA) were measured using goniometer. The parameters were tabulated and statistically analysed. Results and Discussion: The mean length of BG on right side was 89.94 ±6.03 mm and 88.88±8.11mm on left side.

Corresponding Author: Adil Bashir Shah Received: 10/08/2015 Revised: 23/08/2015 Accepted: 25/08/2015 ABSTRACT The morphology and morphometry of the bicipital grooves of the proximal end of humerus were studied in 100 intact dry humeri in the north Indian population. The parameters that were studied included the length, depth and width of the bicipital groove and the maximum length of the humeri. The incidence of supratrochlear ridge in the humeri were noted.The data was tabulated as mean ± SD and statistical comparison was made between the right and left side. No parameter was found to have a statistical significant difference between the two sides (p<.05). Supratrochlear ridge of humerus was found in 42% of the humeri. The present study is an attempt to determine the morphometry of the bicipital groove in the humeri of north Indian population. The data can be useful to anthropologists, orthopaedic surgeons and clinical anatomists. Keywords:
