Plate presetting and arthroscopic reduction technique (PART) for treatment of distal radius fractures.
Arthroscopy has been reported to be an efficient adjunct for the surgical treatment for distal radius fractures (DRF). However, performing wrist arthroscopy during palmar locking plate fixation seems to be troublesome. We have developed a surgical technique involving presetting of a palmar locking plate and an arthroscopic reduction technique (PART) of the fracture that can facilitate the procedure. This study is aimed to investigate the effectiveness of our technique in the treatment of DRF. ⋯ The palmar locking plate in combination with arthroscopic reduction technique (PART) leads to good and excellent results. It can be recommended for all fractures of the distal radius needing operative treatment. Arthroscopic reduction of intra-articular fragments is superior to reduction under fluoroscopy. PART allows also the detection of intra-articular soft tissue lesions such as scapholunate ligament tears and injuries of the triangular fibrocartilage complex.

Review[Arthroscopic repair for ulnar-sided tears of the TFCC].
Accurately performed anatomic and biomechanical studies as well as clinical experience during the last years have widened our knowledge about function and pathology of the distal radioulnar joint (DRUJ) making a differentiated treatment possible. In cases of trauma a rupture of the ulnar part of the triangular fibrocartilaginous complex (TFCC) frequently occurs. An overview is given on the development of different arthroscopic techniques for repair and the state of the art is presented. ⋯ On arthroscopy the TFCC may be evaluated from the radiocarpal joint as well as from its undersurface, from the DRUJ. In cases of avulsion from the fovea, an anatomic reconstruction with reinsertion of the deep part to the bone is indicated and may be performed successfully according to the published studies and our own experience. If a severe instability is found on clinical examination it is to be supposed that more stabilising structures - then only the radioulnar ligaments - are affected and reinsertion of the deep fibres to the fovea may not be sufficient.

Wrist arthroscopy is now widely indicated for diagnosis and treatment of acute or chronic wrist pain, especially for triangular fibrocartilage complex (TFCC) lesions, as a gold standard. In most cases radiocarpal and midcarpal arthroscopy was performed, while DRUJ arthroscopy has been rarely performed because of its difficulties. Recent anatomic and biomechanical studies demonstrated that the radioulnar ligament (RUL), which is the proximal component of the TFCC facing to the DRUJ, is the primary stabilizer of the distal radioulnar joint (DRUJ). ⋯ Although physical examination and imaging diagnosis may indicate a foveal detachment of the TFCC, DRUJ arthroscopy is potential for visualizing the RUL at the fovea. Role of DRUJ arthroscopy should be more important not only for diagnosis of rupture of the RUL but also for decision making of treatment option for RUL tear. DRUJ arthroscopy also demonstrates the joint surface of both the sigmoid notch and ulnar head, and the proximal surface of the TFCC.

With the advancements in arthroscopic technique, arthroscopy has become feasible in most human joints, even those as small as the finger joints. The metacarpophalangeal joints are very well suited for arthroscopy and arthroscopic therapy. Good results have been reported on arthroscopic synovectomy of the metacarpophalangeal joints in rheumatoid arthritis. ⋯ The arthroscopic assistance in the treatment of intraarticular fractures and the capsular shrinkage for instability have been described. However, metacarpophalangeal joint arthroscopy has not been popularised up to now and its role in clinical practice remains to be established. Existing indications will be discussed with respect to our own experience.
