The common symptoms of ulnar impaction syndrome or ulnar abutment syndrome are pain, excess watery fluid collecting in the tissues of the body occasionally, forearm inflexibility, decreased wrist ROM or range of motion as well as softness to palpation dorsally away from to the ulnar head and volar to the ulnar styloid process. Ulnar-sided wrist stability is enhanced via the TFCC, idiopathic ulnar impaction syn-drome and the outcomes of ul-nar shortening osteotomy for this group of patients. 18) [63-69]. Look for ulnar variance, a positive ulnar variance can lead to ulnar impaction syndrome and TFCC tears and degeneration. Regardless of the origin, however, most patients become symptomatic in life, when accumulated and degenerative wear and tear takes its toll on both the ligaments and cartilage, resulting in wrist pain . The increased Ulnar impaction syndrome, also referred to as ulnocarpal abutment, is a degenerative condition of the ulnar side of the wrist resulting from excessive load bearing across the ulnar carpus, triangular fibrocartilage complex (TFCC), and the ulnar head. Arthroscopic wafer procedure is helpful in treating ulnar impaction syndrome or ulnar abutment syndrome. In cadavaric examinations, 30% to 70% of the cases had TFCC perforations and chondromalacia of the ulnar head, lunate and triquetrum. Widening of the distal radio-ulnar joint maybe seen. Wrist Supports for Ulnar Styloid Impaction Syndrome. Ulnar styloid impaction. Ulnar impaction syndrome, also known as ulnar abutment or ulnocarpal impaction or loading, is a painful degenerative wrist condition caused by the ulnar head impacting upon the ulnar-sided carpus with the injury to the triangular fibrocartilage complex (TFCC).. Differentiation from ulnar impingement syndrome is critical, which is due to a shortened ulna that abuts and causes radial remodeling. To fully appreciate how ulnar impaction can result in ulnar-sided wrist pain, it helps to understand the structure and role of the triangular fibrocartilage complex (TFCC) and loading across the ulnocarpal joint (see figure 1). The average age at the time of surgery was 34 years. [1] Conservative management involves injection of triamcinolone , while surgery involves shortening of the styloid process of the ulna via resection . Ulnar styloid impaction: excessively long or fractured ulnar styloid impinges triquetrum. The definition and clinical differentiation are explained. Some causes of ulnar wrist pain include: Wrist fractures. Ulnar impaction syndrome (when the ulna is longer than the radius, which can cause it to “bump into” the smaller wrist bones (Figure 2) Inflammation or irritation of … Arthritis of the joint (s) between bones. [ 17, 18, 21, 22, … Fig. Soft tissue swelling at the ulnar aspect of the wrist is also seen. Fractures associated with radius fractures usually occur as the result of a fall on an outstretched arm. Investigations: XRay: DRUJ visualized with widening on the AP, and dorsal or volar displacement on the lateral. J Hand Surg. These tears are a component of ulnar impaction syndrome. Options for a salvage procedure include partial or complete ulnar head resection (eg, Darrach procedure) or DRUJ arthrodesis with distal ulnar pseudoarthrosis (Sauvé Kapandji procedure)29–32Ulnar styloid impaction syndrome, as the name suggests, involves abnormal contact and impaction between the ulnar styloid and the triquetrum (and adjacent soft tissues)23,26,33–36 (Fig. Ulnar impaction syndrome (UIS), also known as ulnar abutment or ulnocarpal impaction or loading, is a condition in which the ulna of the forearm is too long relative to the radius, resulting in excessive loading on the ulnar side of the wrist. In: Musculoskeletal Physical Examination: An Evidence-Based Approach. Often, a styloid fracture is associated with a distal radius fracture. Type 3 Ulnar Styloid Nonunion. Differential diagnosis. Treatment and prognosis. This is minimal invasive procedure. 14. The origin of ulnar impaction syndrome is a difference of length between the radius and the ulna. Over time, this increased load can lead to a condition called ulnar impaction syndrome. A series of 8 patients each with an excessively long ulnar styloid that was impacting the triquetrum, causing chondromalacia, synovitis, and pain, is presented. There is a history of ulnar … Malanga, GA. (Fig. They affect your ulnar styloid process, a bony projection that helps attach your hand to your arm. Lateral. 2010;26:495. Ulnar impaction syndrome could be secondary to shortening of the radius, although this condition is congenital and present from birth. Ulnar tunnel syndrome is pain, tingling, or numbness in your hand, caused by a pinched nerve in your wrist. Some causes of ulnar wrist pain include: Wrist fractures. Ulnar styloid impaction is due to either a long ulnar styloid process or a nonunited styloid process fracture impacting on the proximal triquetrum [38]. Radiographs shown in Figure 1 revealed neutral ulnar variance, and sclerosis with indentation of the ulnar side of the proximal articular margin of the left lunate, consistent with ulnolunate impaction syndrome. 2: Sammer DM, Shah HM, Shauver MJ, Chung KC. Ulnocarpal stress test: 5 axial load, ulnar deviation, and extension of the wrist. AP. Subscribe to Journal. • Ulnar styloid impaction syndrome is caused by the impaction between the ulnar styloid and the proximal triquetrum, and more commonly develops in wrists with negative ulnar variance (figure 22 on page ). Background: Ulnar styloid triquetral impaction (USTI), one of many causes of ulnar sided wrist pain, is a pathological entity with clear clinical and radiographic features, distinct and different from the impaction of the ulnar head against the lunate or ulno-carpal impaction (UCI). Even though natural degeneration of the ulnocarpal joint is very common, it is important to recognize. Background: Ulnar styloid triquetral impaction (USTI), one of many causes of ulnar sided wrist pain, is a pathological entity with clear clinical and radiographic features, distinct and different from the impaction of the ulnar head against the lunate or ulno-carpal impaction (UCI). 4. Scaphoid Impaction Syndrome. Abstract. With decompression, the styloid process is shaved down to shorten in, thus preventing it … Hand C 21786 32074812 Zhang B 2020 [Early efficacy of lateral unicondylar replacement for lateral compartment osteoarthritis of the knee]. Wrist Supports for Ulnar Styloid Impaction Syndrome. The ulna does not overlie the radius (volar or dorsal displacement is seen). The semiquantitative SPECT/CT shows a 7.51 SUVmax for the ulnar-sided wrist, indicating active ulnar impaction syndrome (UIS). 5. What is ulnar styloid impaction syndrome? Sammer DM, Rizzo M. Ulnar impaction. An ulnar styloid >6 mm in length is commonly regarded as being long. Ulnar styloid impaction is characterized by the impaction of the triquetrum against the ulnar styloid causing chondromalacia, synovitis and ulnar-sided wrist pain. It removes the distal 2 to 4 mm of the ulnar head, while preserving the ulnar styloid process from fracturing via a limited open or an arthroscopic approach. Listen to all episodes here.
