What is infraclavicular fossa?

What is infraclavicular fossa?

The Infraclavicular fossa is an indentation, or fossa, immediately below the clavicle, above the third rib and between the deltoid muscle laterally and medioclavicular line medially.

What is a infraclavicular nerve block?

The infraclavicular brachial plexus block provides a block of the arm below the shoulder. Unlike the axillary approach, it can be performed without abduction of the arm, making it useful for patients with limited shoulder mobility. His goal was to place the local anesthetic on top of the first rib via the axilla.

Is infraclavicular part of brachial plexus?

Introduction: Brachial plexus extends from the neck to the axilla and gives motor and sensory nerves to the upper limb. The brachial plexus has two parts supraclavicular and infraclavicular parts.

What lies in infraclavicular fossa?

The boundaries of the infraclavicular fossa are the pectoralis minor and major muscles anteriorly, ribs medially, clavicle and coracoid process superiorly and humerus laterally. Posterior to the brachial plexus in this region is the scapula.

What is in the Deltopectoral triangle?

The deltopectoral triangle is a triangular depression formed between the clavicle above, lateral border of the pectoralis major medially and the medial border of the deltoid laterally. This narrow triangular area contains investing layers of the clavipectoral fascia and the cephalic vein on its roof which it pierces.

What nerve is missed in Infraclavicular block?

It can provide good analgesia for tourniquet pain but is not suited for the shoulder area. It will not anesthetize the axilla or the proximal medial arm, missing the intercostal and medium cutaneous brachii nerves. It blocks the brachial plexus below the level of the clavicle close to the coracoid process.

Where are the brachial plexus nerves?

The brachial plexus is a network of nerves in the shoulder that carries movement and sensory signals from the spinal cord to the arms and hands. Brachial plexus injuries typically stem from trauma to the neck, and can cause pain, weakness and numbness in the arm and hand.

What is a fossa in English?

: an anatomical pit, groove, or depression. fossa.

Are there lymph nodes in the supraclavicular fossa?

Using the standardized classification of lymph nodes by levels within the neck, any lymph nodes within the supraclavicular fossa would be a designation of Level V lymph nodes. Alternatively, if classified by region, these nodes would be classified as inferior deep cervical lymph nodes. [2]

What is the fossa in the supraclavicular triangle?

The term “fossa,” refers to the shallow depression that overlies the namesake triangle. The vasculature within the region of the supraclavicular triangle is complex, but critical to understand with regards to generating a differential diagnosis for pathology in the region.

Is the brachial plexus part of the supraclavicular fossa?

Also within the supraclavicular fossa is the brachial plexus (C5-T1), a complex network of nerves that is responsible for innervating different portions of the upper extremities and thorax. The structure of the brachial plexus and its exact course into the upper extremity is highly intricate and a separate topic outside this text.

What causes supraclavicular masses to be biopsied via FNA?

In one study, the majority of supraclavicular masses biopsied via FNA were found to be the result of a malignant process, with metastatic spread being far more likely than lymphoma. Congenital anomalies that result in supraclavicular masses can be due to abnormal development of the upper respiratory or gastrointestinal tract.
