: This study examined the reliability of surgeons' estimations as to whether central lesions of the triangular fibrocartilage complex were traumatic or degenerative. A total of 50 consecutive central triangular fibrocartilage complex lesions were independently rated by ten experienced wrist surgeons viewing high-quality arthroscopy videos. The videos were reassessed after intervals of 3 months; at the second assessment surgeons were given the patient's history, radiographs and both, each in a randomized order...

The forearm unit consists of the radius and ulna, a complex and interrelated set of joints (distal radioulnar joint, proximal radioulnar joint) and the soft tissue stabilizers between the 3 bones. Distally, this is represented by the triangular fibrocartilage complex at the wrist, proximally by the annular ligament at the elbow, and in the forearm by the interosseous membrane. Disruptions in any of these structures may lead to forearm instability, with consequences at each of the remaining structures.

Most distal radius fractures result from low-energy mechanisms and can be successfully treated nonsurgically or with a variety of surgical techniques if indicated. High-energy distal radius fractures can involve extensive comminution or bone loss with concomitant ligament, soft-tissue, and neurovascular injuries. In patients with complex distal radius fractures, reconstruction of the distal radius, ulna, and triangular fibrocartilage complex can be challenging. Effective restoration of the bony architecture requires intimate knowledge of the anatomy of the distal radius, a thorough understanding of the goals of treatment, versatility in surgical approaches, and familiarity with multiple fixation options...

PURPOSE: The management of distal radius fractures differs based on the nature of the fracture and the experience of the surgeon. We hypothesized that patients requiring surgical intervention would undergo different procedures when in the care of a surgeon with subspecialty training in hand surgery as compared with surgeons with no subspecialty training in hand surgery. METHODS: We queried the ABOS database for case log information submitted for part II of the ABOS examination...

OBJECTIVE: The present study aimed to assess long-term functional outcome for patients after arthroscopic assisted suture for peripheral tears of the triangular fibrocartilage complex (TFCC). METHODS: Eleven patients, 26 (15-59) years old at time of surgery, 48 (35-78) years old at time of follow-up, were available for this 20-year follow-up. Subjective and objective outcomes, such as range of motion, grip strength, patients' satisfaction, pain, and Mayo Modified Wrist Score, were assessed, as well as asking the question if the patients would have had the surgery done again, knowing the outcome, based on a clinical examination and patient reported questionnaires...

The distal radioulnar joint, the triangular fibrocartilage complex (TFCC) and the wrist are stabilized by many ligaments allowing not only a wide range of motion but also providing sufficient stability. The complex arrangement of carpal ligaments and prosupination around the forearm joint enables multiaxial motion patterns. In the wrist, intra-articular ligaments can be differentiated from extra-articular capsular ligaments as well as intrinsic and extrinsic ligament courses. Imaging is essential for classification of dynamic and static instability patterns...

Gymnastics is a unique sport, which loads the wrist and arms as weight-bearing extremities. Because of the load demands on the wrist in particular, stress fractures, physeal injury, and overuse syndromes may be observed. This spectrum of injury has been termed "gymnast's wrist," and incorporates such disorders as wrist capsulitis, ligamentous tears, triangular fibrocartilage complex tears, chondromalacia of the carpus, stress fractures, distal radius physeal arrest, and grip lock injury.

Management of hand and wrist injuries for athletes often places emphasis on an expeditious return to sport. Arthroscopic techniques have the advantage of directly visualizing joint derangements and correcting them via a minimally invasive approach. This article discusses the evaluation and management of common wrist injuries treated with arthroscopy in athletes, including scapholunate and lunotriquetral injury, triangular fibrocartilage complex tears, hamatolunate impingement, and arthroscopic-assisted reduction of wrist fractures...

Range of motion and stability are important outcome parameters to assess function of the distal radioulnar joint (DRUJ), in particular pronation, supination, and weight-lifting capacity. The DRUJ semiconstrained implant developed by Scheker et al is intended to reproduce all the functions of the triangular fibrocartilage complex and the DRUJ. The aim of the study was to investigate the subjective, clinical, and radiographic results in 10 patients after primary implantation of the semiconstrained DRUJ arthroplasty following DRUJ derangement and painful instability, with an average follow-up of 3 years with a special focus on the complications...

This study is intended as a review of 3Tesla (T) magnetic resonance (MR) imaging of the triangular fibrocartilage complex (TFCC). The recent advances in MR imaging, which includes high field strength magnets, multi-channel coils, and isotropic 3-dimensional (3D) sequences have enabled the visualization of precise TFCC anatomy with high spatial and contrast resolution. In addition to the routine wrist protocol, there are specific techniques used to optimize 3T imaging of the wrist; including driven equilibrium sequence (DRIVE), parallel imaging, and 3D imaging...
