The radius or the radial bone is the forearm bone that runs from the elbow to the wrist and lies on the thumb side of the forearm. The styloid process of the radial bone lies on the distal end of the forearm. Step 1: Apply lubricated gliding strokes repeatedly from the styloid process of the radius to the lateral epicondyle of the humerus to treat abductor pollicis longus, extensor policis brevis and extensor digitorum. De Quervain’s diseaseis also called stenosing tenovaginitisor stenosing tenosynovitis. Step 2: Apply gliding strokes between the radius and ulna from the wrist to the lateral epicondyle of the humerus. Pain is made worse by movement of the thumb and wrist, and may radiate to the thumb or the forearm. The styloid process is separated from the head by a shallow depression where the triangular fibrocartilage attaches. It often causes pain, swelling and difficulty in movement. - Management of Frx: - frxs of ulnar styloid process are assoc w/ frxs of distal radius and TFCC tears; - avulsion frx: - frxs involving lesser portions of ulnar styloid do not seen to be associated w/ significant instability of distal radioulnar joint; - w/ minimally displaced frx involves ulnar styloid, place upper extremity in long arm posterior splint in mid supination for 3-4 weeks; The temporal styloid process is located beneath the ear in humans. RATIONALE AND BASIC SCIENCE Ulnar styloid triquetral impaction (USTI) is often unrecognized, yet it is a relatively common condition in which the ulnar styloid, or fragments of the ulnar styloid, impact into the triquetrum and produce localized pain and dysfunction.

Fractures of the ulnar styloid process can occur as isolated injuries or, more commonly, in association with fractures of the distal radius (, 10,, 32–, 34). This ulnar-sided wrist pain is caused by impaction between an excessively long ulnar styloid process and the triquetral bone.66 The ulnar styloid process is a continuation of the prominent subcutaneous ridge of the shaft of the ulna, which projects distally towards the triquetral bone for a variable distance (2–6 mm). Patients with DQT have difficulty gripping objects and performing their daily activities. This type of fracture usually occurs together with a radius fracture. Symptoms are pain at the radial side of the wrist, spasms, tenderness, occasional burning sensation in the hand, and swelling over the thumb side of the wrist, and difficulty gripping with the affected side of the hand.

The styloid process is a pointed, protruding part of a bone, and it usually serves as an attachment point for muscles, tendons and ligaments. with its triangular shape. This variance affects the force distribution across the wrist and is related to some ulnar pathologies. In adults the styloid process is approximately 25 mm long with a tip which is located between the external and internal carotid arteries, lateral to the pharyngeal wall and the tonsillar fossa. A persistent ulnar styloid ossicle is an anatomical variant where the ulna styloid ossification center fails to unite with the ulna.. Radiographic features. The ulna is the bone on the outer, or little pinky finger, side of the arm. The styloid process protrudes from the petrous temporal bone and connects to the stylohyoid ligament as well as the stylohyoid, stylopharyngeus, and … See The P.R.I.C.E.

Symptomatic or painful nonunion of the ulnar styloid process without instability of the distal radioulnar joint is an infrequent problem. In this report, we describe a patient who presented to our department with styloid process elongation and fracture. Ulnar variance refers to the lengths of the distal articular surfaces of the radius and ulna. Some patients complain of slight local redness, swelling and heat. Radial styloid process. Breakage of the radius at the radial styloid is known as a Chauffeur's fracture; it is typically caused by compression of the scaphoid bone of the hand against the styloid. Proper diagnosis and treatment is necessary to preserve the functioning of wrist joint. Pain also occurs with resisted thumb extension or abduction, and Finkelstein’s test (Fig. The pain is localized to the area over the radial styloid process and is associated with increasing functional disability if the inflammatory process remains untreated. Synonyms for styloid process in Free Thesaurus. It is a degenerative condition in which the ulnar head abuts the triangular fibrocartilage complex (TFCC) and ulnar-sided carpals. The main symptoms are protuberance and pain of the styloid process of the radius, accompanied by aggravation of pain during the movement of the wrist and thumb. What are synonyms for styloid process? De Quervain syndrome causes pain over the styloid process of the radius. This is due to the passage of the inflamed extensor pollicis brevis tendon and abductor pollicis longus tendon around it. The styloid process of the radius is a useful landmark during arthroscopic resection of the scaphoid bone. 3) (1) Radial side De Quervain disease is suspected when there is tenderness in the first compartment of the extensor tendon.

(Translated article: Muenchener Medizinische Wochenschrift 1912, 59, 5 … The forearm comprises two bones: the radius and the ulna. Injuries of the short radial collateral ligament lead to periosteal new bone formation at the ligamentous insertion; this is called an enthesophyte. The symptoms of a broken wrist, including an ulnar styloid fracture, include: 1. Ulnar impaction syndrome, also called ulnocarpal abutment syndrome, is a common cause of ulnar-sided wrist pain.
