The distal radioulnar joint (DRUJ) is a complex articulation allowing significant rotational and translational motion. Stability of the DRUJ depends on bony contact, intrinsic stabilizers of the triangular fibrocartilage complex, and extrinsic stabilizers of the distal forearm. Understanding the anatomy of this articulation is paramount in clinical decision making for the treatment of disorders...

Introduction Fractures of the ulnar styloid frequently accompany fractures of the distal radius, however, there is no conclusive evidence whether it influences the final outcome of the treatment. The majority of studies show no negative effect of ulnar styloid fractures on final outcome, when the fracture of the distal radius is fixed, preferably by a locking plate [1,2]. Some authors, however,...

Disorders of the distal radioulnar joint are a major source of ulnar-sided wrist pain. Fortunately, our understanding of the anatomy, joint mechanics, and pathophysiology of this area has increased greatly in recent years, making resolution of many of these problems feasible. In most cases, an accurate diagnosis can be made, and successful treatment can then be prescribed. This review covers va...

BACKGROUND Idiopathic arthrofibrosis occurs in 3-4% of patients who undergo total knee arthroplasty (TKA). However, little is known about the cellular or molecular changes involved in the onset or progression of this condition. To classify the histomorphologic changes and evaluate potential contributing factors, periarticular tissues from the knees of patients with arthrofibrosis were analyzed ...

Triangular fibrocartilage complex (TFCC) tears are a common source of ulnar sided wrist pain. Originally described by Palmer, in 1981, as a complex of several structures, our understanding of the anatomy and the function of the TFCC has been refined by histologic studies. The TFCC plays an important role in load bearing across the wrist as well as in distal radioulnar joint (DRUJ) stabilization...

The anterior cruciate ligament (ACL)-to-bone interface constitutes a complex, multi-tissue structure comprised of contiguous ligament, non-mineralized fibrocartilage, mineralized fibrocartilage, and bone regions. This composite structure enables load transfer between structurally and functionally dissimilar tissues and is critical for ligament homeostasis and joint stability. Presently, there i...

A recent development in the field of tissue engineering is the rise of all-biologic, scaffold-free engineered tissues. Since these biomaterials rely primarily upon cells, investigation of initial seeding densities constitutes a particularly relevant aim for tissue engineers. In this study, a scaffold-free method was used to create fibrocartilage in the shape of the rabbit knee meniscus. The obj...

INTRODUCTION Wrist arthroscopy has evolved since its inception to become an essential diagnostic and therapeutic tool for the management of various wrist disorders. Our study aimed to examine the outcomes of arthroscopic debridement in the treatment of scapholunate (SL), lunotriquetral (LT) and triangular fibrocartilage complex (TFCC) tears. METHODS We conducted a retrospective review of 68 c...

PURPOSE To determine whether traumatic triangular fibrocartilage complex (TFCC) tears treated by arthroscopic repair have improved functional outcome scores, range of motion, grip strength, and pain relief compared with those repaired using an open surgical technique. METHODS From 1997 to 2006, 75 patients had repair of traumatic TFCC tears. Thirty-six patients had arthroscopic TFCC repair, a...

A retrospective survey for debridement with or without wafer distal ulna resection was performed. Forty six patients responded to a questionnaire on pain, disability and time off work. The mean DASH score decreased from 42 to 28 on average. Thirty two patients were satisfied. The pain was considered severe in 12 patients. There were significant differences in the outcome between debridement onl...
