Wrist arthroscopy

Background  Midcarpal instability is an uncommon entity characterized by pain and clunking as the wrist moves from radial deviation to ulnar deviation. Management is primarily nonoperative. In patients with persistent symptoms, operative treatments are divided into soft tissue reconstruction and limited midcarpal arthrodesis. Case Description  We present a rare case of radial midcarpal instability associated with radioscaphocapitate (RSC) ligament injury. A 20-year-old man presented with radial-sided wrist pain and clunking with radial deviation after a fall...

Background In symptomatic chronic injury of ulnar-sided tear of the triangular fibrocartilage complex, reconstruction techniques involving foveal reconstruction with palmaris longus tendon graft using the method described by Bain have been described with good outcomes. Description of Technique With increasing popularity of wrist arthroscopy to address various wrist pathologies, we present our technique of arthroscopic foveal reconstruction. We also include a step-by-step description of the procedure with illustrations, with aims to aid surgeons in executing it Conclusion Unlike other arthroscopic techniques described, this involves single osseous ulnar tunnel and performed completely arthroscopically, allowing an end result similar to Bain's open technique...

Background  Wrist arthroscopy has become a commonly used tool for the management of adults with distal radius fractures (DRFs), although its implementation requires technical competence. This systematic review and meta-analysis appraised the available evidence concerning the contribution of wrist arthroscopy to the functional and radiological outcomes of patients with DRFs operated with arthroscopic assistance. Methods  Randomized control trials were identified through five principal electronic databases on May 31, 2022: Web of Science, Scopus, EBSCO, Embase, and PubMed...

Background  The results of Mathoulin's arthroscopic dorsal capsuloligamentous reconstruction (ADCLR) are excellent in many patients with scapholunate instability, though less consistently good in higher grade instabilities. The purpose of this article is to describe a novel technique of volar scaphotrapeziotrapezoid (STT) reconstruction which may be used to augment rotational control of the scaphoid, in conjunction with the ADCLR, for use in European Wrist Arthroscopy Society (EWAS) grade IV/V instabilities...

Background  The integrity of the foveal insertion of the triangular fibrocartilage complex (TFCC) is currently assessed by inference using the hook test. Using dry arthroscopic techniques, the primary author observed that many patients with painful distal radioulnar joint (DRUJ) instability and a positive hook test had an intact foveal insertion. This study was performed to determine whether a positive hook test is a reliable index of a tear of the foveal insertion. Technique  The hook test is performed using a probe to elevate the TFCC off the ulna head toward the articular surface of the lunate...

BACKGROUND: The NanoScope, given its smaller size, may be further from critical structures when establishing volar wrist arthroscopy portals compared to the traditional 2.7-mm arthroscope. METHODS: Ten fresh-frozen latex-injected cadaver specimens were utilized. The volar radial (VR) and volar ulnar (VU) portals were created using an inside-out approach. The volar radial midcarpal (VR-MC) and volar ulnar midcarpal (VU-MC) portals were created using an inside-out approach...

BACKGROUND: The purpose of this study was to determine the predictive value of the clenched fist stress views in identifying scapholunate ligament injuries. METHODS: An institutional review board-approved retrospective chart review was conducted of adult patients who underwent diagnostic arthroscopy with a ligamentous wrist injury from 2015 to 2020. Standard posteroanterior, lateral, and clenched fist stress radiographs were reviewed and scapholunate ligament gaps recorded...

BACKGROUND: Currently, there were two major surgical methods for arthroscopic triangular fibrocartilage complex (TFCC) foveal repair: suture anchor (SA) and transosseous suture (TOS). The purpose of this systematic review is to examine the relevant outcome improvement and safety of SA and TOS technique. METHODS: Literature review of electronic databases for studies investigating the effects of SA and TOS in patients undergoing arthroscopic TFCC foveal repair was performed...

BACKGROUND: Triangular fibrocartilage complex (TFCC) injuries commonly manifest as ulnar-sided wrist pain and can be associated with distal radioulnar joint (DRUJ) instability and subsequent wrist functional decline. This study aimed to assess the diagnostic value of MRI compared to wrist arthroscopy in identifying traumatic TFCC injuries and to determine the distribution of different TFCC injury subtypes in a normal clinical setting. METHODS: The data of 193 patients who underwent both preoperative wrist MRI and wrist arthroscopy were retrospectively reviewed...

Background  Surgical procedure selection for carpal arthritis depends on which articular surfaces are affected, but there is no consensus on how to preoperatively evaluate cartilage surfaces. Despite advances in cross-sectional imaging, the utility of advanced imaging for preoperative decision-making has not been well established. Objectives  Our objective was to assess if there is an added value to presurgical advanced imaging or diagnostic procedures in planning for carpal arthrodesis or carpectomy and to determine what imaging or diagnostic procedures influence surgical treatment options...

Septic arthritis of the wrist though decidedly rare can lead to severe consequences with loss of form and function of the hand. The approach to diagnosis and treatment remains challenging and may need multiple surgeries, prolonged hospital stays along with intravenous antibiotics for restitution of a pain and disease-free functioning wrist. Arthroscopic washout of the wrist joint, has paved the way for a less invasive and more effective approach to the management of the condition reducing the number of operations needed and the need for open wrist washout...

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...

OBJECTIVE: Scaphoid nonunion advanced collapse (SNAC) is a relatively common and debilitating wrist disorder yet its treatment remains challenging and controversial. We aim to describe a novel technique of a dual arthroscopic and robotic assisted four-corner fusion (4CF) in the treatment of SNAC wrist. METHODS: In this study, we describe an original arthroscopic and robotic assisted 4CF, which is novel and currently unpublished in literature. The surgical approach included these predefined steps: arthroscopic resection of the scaphoid, radial styloid and of diseased cartilage between the capitate-lunate joint and triquetrum-hamate joint, correction of Dorsal Intercalated Segment Instability (DISI) deformity of the wrist and robotic assisted 4CF performed percutaneously with screws...

PURPOSE: To characterize the prevalence and incidence of in-game hand and wrist injuries in the National Basketball Association (NBA), to determine the factors associated with an equal or greater player efficiency rating (PER), and to determine the factors associated with an equal or greater true shooting percentage (TS%) 2 years after a hand and wrist injury using a large-scale national database of NBA players. METHODS: Injury data from seasons 2015-2016 to 2020-2021, with exclusion of the 2019-2020 because of abbreviated play due to the coronavirus disease 2019, were extracted from a public online database, Pro Sports Transactions...

INTRODUCTION: COVID-19 had numerous objective and subjective effects on resident physician education. We intended to examine objective changes in orthopedic education that occurred during the COVID pandemic and other trends from 2018 to 2022 by analyzing surgical case logs from Accreditation Counsel for Graduate Medical Education (ACGME) approved American orthopedics programs. We hypothesized that surgical case load during the COVID pandemic would remain similar to pre-pandemic levels and case logs would show a general upward trend...

OBJECTIVE: To explore the effectiveness of arthroscopic treatment of scaphoid fracture nonunion with bone graft and Kirschner wire combined with screw fixation. METHODS: The clinical data of 14 patients with scaphoid fracture nonunion who met the selection criteria between February 2021 and September 2022 were retrospectively analyzed. There were 13 males and 1 female with an average age of 32 years ranging from 17 to 54 years. The time from injury to operation ranged from 6 to 15 months, with an average of 9...

OBJECTIVES: Scaphoid nonunion remains a challenging problem to manage with no general consensus on its treatment recommendations. We propose a novel minimally invasive (MIS) technique of arthroscopic bone grafting (ABG) with robot-assisted fixation for the treatment of scaphoid nonunions. METHODS: Patients with radiographically proven scaphoid nonunion treated by this novel surgical technique were included. Following arthroscopic debridement and iliac crest bone grafting, the scaphoid was fixed percutaneously using either multiple Kirschner (K)-wires or a headless compression screw using a robotic navigation system...

In advanced scapholunate instability, a scapholunate repair by open or arthroscopic ligamentoplasty is indicated. Although the radiographic results and functional scores are more or less satisfactory for open ligamentoplasty, it is often responsible for a decrease in joint amplitude postoperatively. Arthroscopic techniques are therefore of great interest, since they respect the joint capsule, but they remain technically difficult and demanding surgeries, requiring a good deal of experience in arthroscopy and using bone tunnels that are potentially a source of complications, as well as pinning to the palmar side of the wrist, which is potentially dangerous for the palmar structures of the wrist...

Ulnar bursa of the hand invaginates the flexor digitorum superficialis and flexor digitorum profundus tendons of the little, ring, long, and index fingers. Distension of this bursa can have an inflammatory or infective cause. It can also originate from pathology of another site (e.g., degenerative wrist joint). Because of the tough overlying palmar aponeurosis, distended ulnar bursa can have swelling at a remote site. The distended ulnar bursa can also have compressive neuropathy to the ulnar nerve and median nerve...

Background: Arthroscopic scaphotrapeziotrapezoid (STT) fusion (ASTTF) has emerged in the recent decade as an option for traditional open surgery. This retrospective study describes our technique and results of ASTTF. Methods: Medical records and radiological data of patient who had undergone ASTTF between 2014 and 2022 in two tertiary hospitals were reviewed. Results: Five ASTTF in four patients were identified. The mean age of the patients were 52.4 years. Fusion was achieved in four out of five wrists (80%)...
