“…Nonetheless, this study posed several limitations, considering no arthroscopy instruments were used. Thus, it was attempted to mitigate this with the fact that all measurements were taken practically from the center of arthroscopy portal sites, and the proposed classification for each portal can always be applied with a simultaneous width evaluation of current arthroscopy tools, whether for example, the standard 2.7mm wrist arthroscopy or the newly implemented 1.9mm nanoscope [26].…”

During wrist arthroscopy, the wrist joint can be visualized from almost every perspective through a combination of standard dorsal and volar arthroscopic portals. This cadaveric study aims to compare all wrist portals described in terms of their safety in order to rank them according to the distance from the nearest structure at risk for arthroscopic wrist procedures. Twenty-nine cadaveric formalin-embellished upper limbs were examined. Needles were inserted at dorsal and volar portal sites to perform the measurements. During the subsequent dissection, distances were measured as the shortest possible distance from the nearest structure at risk for each portal. Safe zones were determined for all portals, and the safety classification of arthroscopic wrist portals was proposed, ranking them from the safest to the most perilous. Applying the proposed safety classification to arthroscopic practice, wrist arthroscopy can be performed with a lower risk of iatrogenic complications arising from the implementation of the wrist portals.

“…2,3,23 The present experience with single-portal wrist arthroscopy can help as a starting point for future developments with the increasing use of smaller and more flexible arthroscopes, which have the advantage of size and ease of handling. Some works confirm how the nanoscope (a 1.9-mm flexible arthroscope with a chip camera incorporated into its tip) is excellent for this purpose, 14,[24][25][26] although comparative studies and larger series are needed.…”

Purpose This study aimed to describe the technique, indications, and advantages of the single-portal arthroscopic approach for the diagnosis and staging of chronic radial-sided disorders, including scapholunate interosseous ligament (SLIL) tear, scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) deformities. Methods The single portal technique was used in 138 patients affected by suspected SLIL lesions, SLAC and SNAC wrist injuries with positive clinical symptoms and inconclusive imaging (X-ray and MRI). It was used to grade the nature of the SLIL lesion and the extension of the osteochondral damage in the SLAC and SNAC wrist deformity to guide appropriate treatment. Results Patients were divided into group 1 (SLIL: 45 cases), group 2a (SLAC: 65 cases), and group 2b (SNAC: 28 cases). In group 1, stage 4 SLIL lesions were confirmed in 36 cases and 9 were assessed as SLAC wrist deformity. In group 2a, single-portal arthroscopy confirmed the preoperative diagnosis in 74% of cases. In the remaining 26% of patients, arthroscopy modified the preoperative diagnosis: 1 case of SLAC 1 resulted in SLAC 2, 14 cases of SLAC 2 resulted in SLAC 3, 1 case of SLAC 3 resulted in SLAC 2. A case of SLAC 2 turned out to be an SLIL lesion stage 4. In group 2b, single-portal arthroscopy confirmed the preoperative diagnosis in 86% of cases. In the remaining 14% (4 cases), it modified the preoperative diagnosis: 1 of SNAC 1 resulted in SNAC 2 and the other in SNAC 3, 1 case of SNAC 2 turned out to be an SNAC 3, and 1 case of SNAC 3 resulted in SNAC 4. Conclusion Single-portal wrist arthroscopy modified the preoperative diagnosis of wrist pathology in 42 patients over 138 cases. The use of single-portal wrist arthroscopy should be considered in the evaluation of the radiocarpal and midcarpal joints to allow accurate visualization of the joint surfaces for surgeon and patient planning. Type of Study/Level of Evidence Observational study level of evidence IV.

Structurally intact and functionally incompetent foveal triangular fibrocartilage complex injuries

Injury to the triangular fibrocartilage complex (TFCC) may result in ulnar wrist pain with or without instability. One component of the TFCC, the radioulnar ligaments, serve as the primary soft-tissue stabilizer of the distal radioulnar joint (DRUJ). Tears or avulsions of its proximal, foveal attachment are thought to be associated with instability of the DRUJ, most noticed during loaded pronosupination. In the absence of detectable instability, injury of the foveal insertion of the radioulnar ligaments may be overlooked. While advanced imaging techniques such as MRI and radiocarpal arthroscopy are well-suited for diagnosing central and distal TFCC tears, partial and complete foveal tears without instability may be missed without a high degree of suspicion. While technically challenging, DRUJ arthroscopy provides the most accurate method of detecting foveal abnormalities. In this annotation the spectrum of foveal injuries is discussed and a modified classification scheme is proposed. Cite this article: Bone Joint J 2023;105-B(1):5–10.
