BACKGROUND: Triangular fibrocartilage complex (TFCC) injuries are a known cause of ulnar-sided wrist pain. Wrist arthroscopy is the gold standard for diagnosis of these lesions and is becoming a more frequent method of treatment. Isolated radial-sided tears are uncommon and treatment of these lesions is controversial. There are few reports on repair techniques. Here we report on a novel arthroscopic, all-inside technique for traumatic radial-sided TFCC tears that resulted in full range of motion, significant improvement in pain, and ultimately return to sport...

BACKGROUND: Ulnar shortening osteotomy (USO) is a widely adopted procedure with excellent outcomes. However, delayed union or nonunion has occasionally been observed. The purpose of this retrospective case-control study was to identify variables affecting osseous consolidation after USO in patients with ulnar impaction syndrome. METHODS: The study included 325 patients who had undergone USO between March 2008 and March 2014. We evaluated the association between union and basic demographic factors as well as preoperative pain (assessed on a visual analog scale [VAS]), range of wrist motion, grip strength, and modified Mayo wrist score...

The distal radioulnar joint allows the human to rotate the forearm to place the hand in a desired position to perform different tasks, without interfering with the grasping function of the hand. The ulna is the stable part of the forearm around which the radius rotates; the stability of the distal radioulnar joint is provided by the interaction between ligaments, muscles and bones. The stabilizing structures are the triangular fibrocartilage complex, the ulnocarpal ligament complex, the extensor carpi ulnaris tendon and tendon sheath, the pronator quadratus, the interosseous membrane and ligament, the bone itself and the joint capsule...

The radioulnar ligament of the triangular fibrocartilage complex (TFCC), especially the deep fibers inserted at the ulnar fovea, is the key component for the distal radioulnar joint (DRUJ) stability. Traumatic injuries to the TFCC foveal insertion would cause DRUJ instability. Traditionally, arthroscopic techniques of the TFCC repair are suturing the ulnar-sided disruption peripherally to the dorsal or ulnar capsule instead of suturing the TFCC to the fovea and thus fail to restore the DRUJ stability if the TFCC is detached from the fovea...

BACKGROUND: The injury of the triangular fibrocartilage complex (TFCC) is a common cause of ulnar-sided wrist pain. The aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging (MRI) could demonstrate the detailed complex anatomy of TFCC in Chinese. METHODS: Fourteen Chinese cadaveric wrists (from four men and three women; age range at death from 30 to 60 years; mean age at 46 years) and forty healthy Chinese wrists (from 20 healthy volunteers, male/female: 10/10; age range from 21 to 53 years with a mean age of 32 years) in Beijing Jishuitan Hospital from March 2014 to March 2016 were included in this study...

Background: This study addresses the prevalence of discrete pathophysiology accounting for patients' symptoms during diagnostic wrist arthroscopy in individuals with wrist pain without a specific preoperative diagnosis. Secondarily, we determined the number and type of surgeries subsequent to diagnostic wrist arthroscopy. Methods: Between January 2000 and January 2015, 135 diagnostic wrist arthroscopies were performed by 12 surgeons in 3 urban academic hospitals. We recorded the diagnostic findings of diagnostic wrist arthroscopy and any subsequent surgeries...

PURPOSE: Certain distal ulna fractures may contribute to distal radioulnar joint (DRUJ) instability. We hypothesized that residual distal ulna translation could affect DRUJ stability by slackening the distal interosseous membrane (DIOM). We aimed to test this hypothesis in a cadaver model. METHODS: We created an ulnar translated distal ulna fracture model in 6 cadavers. Dorsal and palmar displacements of the ulna relative to the radius were measured and DRUJ instability was staged under the following conditions: (1) 0-, 2-, and 4-mm ulnar translation of the distal ulna with an intact triangular fibrocartilage complex (TFCC) and DIOM; (2) 0-, 2-, and 4-mm translations with TFCC divided and an intact DIOM; and (3) a 0-mm translation with TFCC and DIOM divided...

Introduction. The triangular fibrocartilage complex (TFCC) provides both mobility and stability of the radiocarpal joint. TFCC lesions are difficult to diagnose due to the complex anatomy. The standard treatment for TFCC lesions is arthroscopy, posing surgery-related risks onto the patients. This feasibility study aimed at developing a workup for soft-tissue reconstruction using clinical imaging, to verify these results in retrospective patient data. Methods. Microcomputed tomography (μ-CT), 3 T magnetic resonance imaging (MRI), and plastination were used to visualize the TFCC in cadaveric specimens applying segmentation-based 3D reconstruction...

PURPOSE: We evaluate the clinical and functional outcome of open primary repair of acute TFCC tears in distal radius fracture, when there is gross intraoperative distal radioulnar joint (DRUJ) instability after fixation of the distal radius, in the absence of an ulnar styloid fracture or when the ulnar fracture fragment is too small to be fixed. METHODS: A retrospective review of our institution's distal radius fracture database over a 4-year period (January 2010 to December 2013)...

We report our 11-year experience of performing arthroscopically assisted triangular fibrocartilage complex reconstruction in the treatment of chronic distal radio-ulnar joint instability resulting from irreparable triangular fibrocartilage complex injuries. Eleven patients were treated. Three skin incisions were made in order to create radial and ulna tunnels for passage of the tendon graft, which is used to reconstruct the dorsal and palmar radio-ulnar ligaments, under fluoroscopic and arthroscopic guidance...

The classical definition of 'Palmer Type IB' triangular fibrocartilage complex tear, includes a spectrum of clinical conditions. This review highlights the clinical and arthroscopic criteria that enable us to categorize five classes on a treatment-oriented classification system of triangular fibrocartilage complex peripheral tears. Class 1 lesions represent isolated tears of the distal triangular fibrocartilage complex without distal radio-ulnar joint instability and are amenable to arthroscopic suture. Class 2 tears include rupture of both the distal triangular fibrocartilage complex and proximal attachments of the triangular fibrocartilage complex to the fovea...
