The purpose of this article is to describe a technique of restoring stability or congruency to the distal radioulnar joint (DRUJ) by osteoplasty or osteotomy of the sigmoid notch, where abnormalities in the osseous anatomy have resulted in DRUJ instability. This technique addresses the osseous cause to DRUJ instability and avoids the need for complex soft tissue procedures to treat chronic volar instability or salvage procedures to treat dorsal instability of the DRUJ associated with an…

Sigmoid notch reconstruction and limited carpal arthrodesis for a severely comminuted distal radius malunion: case report.
Anatomic foveal reconstruction of the triangular fibrocartilage complex with a tendon graft.
TLDR
The foveal reconstruction technique has the advantage of providing a robust anatomically based reconstruction of the TFCC to the fovea, which stabilizes the DRUJ and the ulnocarpal sag.
Nonunions of the Wrist and Hand
TLDR
This chapter will discuss nonunions of the wrist and hand, their sequelae, and treatment options ranging from reconstructions to salvage procedures.
Ulnar shortening: results for treatment of distal radioulnar joint pathology and conversion to DRUJ replacement arthroplasty.
TLDR
A specific sigmoid notch type does not present risk for OA and does not appear to be related to conversion to DRUJ arthroplasty, and its use may delay the need forDRUJ secondary procedures, protecting the native joint.
Distal radioulnar joint volar instability after ligament reconstruction failure treated with sigmoid notch osteotomy.
TLDR
A 22-year-old man presented with a 9-month history of right wrist pain with volar instability after a fall, which was treated conservatively, and a sigmoid notch osteotomy of the volar rim was performed, which restored stability.
Triangular Fibrocartilage Complex: An Anatomic Review
TLDR
Improved understanding of the complicated anatomy of the triangular fibrocartilage complex coupled with recent advances in surgical techniques will improve orthopaedic care.
Periulnar Injuries Associated with Distal Radius Fractures
Residual dysfunction after a fracture of the distal radius is most often mild but may give rise to significant impairment especially in the younger active population. The symptoms often manifest ar…
Ulnar sided wrist pain and distal radioulnar joint osteoarthritis; is surgical arthroplasty enough?
TLDR
It is suggested that pathology involving the ulnar-wrist complex is often a syndrome consisting of multiple related diagnoses including but not limited to arthritis of the DRUJ, and multiple procedures may be needed or a more aggressive approach such as ulnar head replacement may be indicated so that pathology at both the distal radioulnar and ulnocarpal joints is addressed concomitantly.

TLDR
The case of painful dislocation on supination was successfully treated by osteoplasty of the volar lip of the sigmoid notch to create a buttress that prevented volar dislocation.

TLDR
The ECU appears to play a role in stabilizing the distal radioulnar joint and when dislocation of the ECU tendon is noted intraoperatively, reconstruction of the fibrous osseous canal should be done.
The distal radioulnar joint.
TLDR
The distal radioulnar joint (DRUJ), stabilized by the triangular fibrocartilage complex (TFCC), and TFCC injuries are part of the common pattern of injuries seen with distal radius fractures.
Management of Complex Dislocations of the Distal Radioulnar Joint
TLDR
The authors reviewed their experience in the treatment of complex dislocations of the distal radioulnar joint and preferred to treat these by fixation of the ulnar styloid using a tension band wiring technique.
An anatomic reconstruction of the distal radioulnar ligaments for posttraumatic distal radioulnar joint instability.
TLDR
The procedure is an effective treatment for an unstable distal radioulnar joint when its articular surfaces are intact and the other wrist ligaments are functional, and it can be used in combination with a distal radius corrective osteotomy.
Anatomy of the distal radioulnar joint.
TLDR
The distal radioulnar joint (DRUJ) is of the utmost importance in treatment of fractures of the distal radius, and the ligament is therefore of particular importance to the stability.
