conical ligament The conical tuberosity is attached to the clavicle, and the conical tuberosity is located posteromedial to the trapezoidal tubercle. From top to bottom, the conus ligament is in the shape of a lower cusp.

Which muscles are attached to the tuberosity of conus?

• Trapezius.
• Latissimus dorsi.
• levator scapulae.
• Rhomboid muscle.
• Rhomboid muscle.
• pectoralis major.
• pectoralis minor.
• serratus anterior.

What muscle is attached to the coracoid tubercle?

The coracoid process is the attachment point for several muscles.This pectoralis minor Attached to the medial side of the coracoid process. The coracobrachialis is attached to the medial cusp and the short head of the biceps is attached to the lateral cusp.

What joint is supported by the conus ligament?

Coracoclavicular Ligament: Consists of conus ligament and trapezoid ligament (does not actually touch the joint).The syndesmotic ligament is the main supporting ligament exchange joint. The coracoclavicular ligament extends from the coracoid process to the underside of the clavicle, near the AC joint.

What is the trapezoid attached to?

trapezoid ligament Originates from the upper surface of the coracoid process. It attaches to the trapezoid line (or ridge) on the lower surface of the clavicle. The anterior edge of the trapezoidal ligament is free.

What are trapezoidal lines and conical nodules attached to?

conical ligament The conical tuberosity is attached to the clavicle, and the conical tuberosity is located posteromedial to the trapezoidal tubercle. From top to bottom, the conus ligament is in the shape of a lower cusp.

What is the coracoid process related to?

The coracoid process is also a key anchor for many tendon and ligament attachment points.These include pectoralis minor, coracobrachialis, and biceps brachii tendonsas well as the coracoclavicular, coracohumeral, coracoacromial, and transverse scapular ligaments.

Is the AC joint the same as the rotator cuff?

The rotator cuff covers the head of the upper arm bone and connects it to the shoulder blade. alternating current (acromioclavicular joint) joints are formed where the shoulder blade (acromion) and part of the collarbone meet and are joined together by tough tissue (ligaments) that act like tethers to hold the bones in place.

What movement does the acromioclavicular joint allow?

AC joints are planar synovial joints, and under normal physiological conditions only allow glidingSince it connects the scapula to the chest, it allows additional range of motion of the scapula and assists with arm movements such as shoulder abduction and flexion.

Which anatomy is the weakest part of the clavicle?

The most common fracture site is The junction between the two curvatures of the bone, which is the weakest point. This causes the sternocleidomastoid to lift up medially, which can lead to perforation of the overlying skin.

What is the most common Moi for glenohumeral subluxation?

anterior dislocation is the most common, accounting for 97% of all shoulder dislocations. The injury mechanism is usually a blow to the abducted, externally rotated, and extended limb. It can also occur when the back of the humerus is stressed or falls on the outstretched arm.

What is the greater tuberosity of the humerus attached to?

The greater tuberosity is the prominent area of ​​the bone at the top of the humerus and is the attachment point of the two greater tuberosities, Strong rotator cuff muscles – supraspinatus and infraspinatus.

What muscles are attached to the lesser tuberosity of the humerus?

subscapularis Originates from the subscapular fossa and ends at the lesser tubercle of the humerus. The muscle internally rotates and adducts the humerus. The biceps tendon lies beneath the subscapularis tendon in the biceps groove.

What are conical nodules used for?

On the posterior inferior side of the clavicle, near the junction of the prism with the flattened portion, is a rough bulge, the conical tubercle (or coracoid tubercle); this, in the bone’s natural position, extends beyond the coracoid process of the scapula, and attached to the conical ligament.

What is a conical nodule?

The conical tubercle also known as the coracoid tubercle (not to be confused with the coracoid process of the scapula) is bony protrusion on the lower surface of the lateral third of the clavicle.

Where is the coracoclavicular ligament attached?

attach, Below, to the upper surface of the coracoid process; On, to the oblique ridge on the lower surface of the clavicle. Its anterior edge is free; its posterior edge is attached to the conical ligament, the two forming a posteriorly projecting angle through their junction.

How do you treat acromioclavicular joint pain?

Treatment goals and options for acromioclavicular (AC) joint injuries

1. Frozen shoulders.
2. Put your arms on the sling to reduce movement.
3. Take an NSAID, such as ibuprofen or naproxen, to help relieve pain.

What nerve passes through the acromioclavicular joint?

suprascapular nerve Mainly responsible for most of the sensory innervation of the acromioclavicular joint. In this anatomical study, we describe in detail the anatomy of the acromioclavicular joint innervated by sensory nerves branching from the suprascapular nerve.

What are degenerative changes of the acromioclavicular joint?

acromioclavicular osteoarthritis is a type of shoulder arthritis that involves degenerative changes to the cartilage and other structures in the acromioclavicular joint, causing pain, stiffness, and weakness in the front of the shoulder.

What happens if a torn rotator cuff goes untreated?

Rotator cuff tear if left untreated Can severely limit function and range of motion. Tears also increase over time. This can cause a partial rotator cuff tear to develop into a full tear.

Are push-ups bad for AC joints?

What are the three processes of the scapula?

The scapula has three angles (superior/medial, lateral, inferior), three borders (medial, lateral/axillary, and superior), and two surfaces (ventral and dorsal). There are three processes in the scapula: acromion, spine and coracoid.

Is the coracoid process palpable?

The coracoid is Palpable below the lateral end of the clavicle (clavicular)It is also known as the « Surgeon’s Beacon » because it is a landmark for avoiding neurovascular damage.

These two ligaments (Trapezoid and Conus ligaments) The coracoid process of the clavicle that joins the scapula. These tiny ligaments (with their clavicle joints) play an important role in keeping the scapula connected to the collarbone and therefore keeping the shoulder « square ».
