Arthroscopic Management of Ulnocarpal Impaction Syndrome and Ulnar Styloid Impaction Syndrome.

Both ulnocarpal impaction syndrome and ulnar styloid impaction syndrome can produce ulnar wrist pain. The definition and clinical differentiation are explained. The relevant anatomy, biomechanics, causes, diagnosis, and arthroscopic treatments, as well as the surgical indications, techniques, and outcomes of these syndromes are discussed in detail.

Coronal Fractures of the Scaphoid: A Review.

Coronal (or frontal plane) fractures of the scaphoid are distinctly uncommon. There are few published reports of coronal fractures of the scaphoid. This fracture is often missed on the initial X-ray films.

Scapholunate and lunotriquetral injuries: arthroscopic and open management.

It has become clear that the stability of the scapholunate joint is not dependent wholly upon the scapholunate interosseous ligament but rather upon both primary and secondary stabilizers, which form a scapholunate ligament complex. Each case of scapholunate instability is unique and therefore should be treated with tissue-specific repairs, which may partly explain why a single procedure cannot successfully restore joint stability in every case. Not all lunotriquetral ligament tears are traumatic.

Use of arthroscopy for the treatment of scaphoid fractures.

Arthroscopy allows the surgeon to use smaller incisions and still have predictable outcomes in the treatment of scaphoid fractures. Similar to large joint arthroscopy, the ability to visualize the fracture site allows one to not only fine tune the reduction and to assess the vascularity of the fracture fragments but to evaluate and treat any associated soft tissue injuries that may affect the end result. Specialized equipment and a basic knowledge of wrist arthroscopy however are required.
