The current literature talks about symptomatic distal radioulnar joint injuries in Galeazzi fracture-dislocations and the various approaches to managing instability. However, unfortunately, there is a dearth of data on the true incidence of injury to the triangular fibrocartilage in the backdrop of the severity of the mechanism of Galeazzi fractures and the damage it may cause as direct inspection of the triangular fibrocartilage complex is not done routinely as a part of management of such cases. We conducted a retrospective review of six consecutive patients with Galeazzi fracture-dislocations. Wrist arthroscopy was performed in these cases, which revealed complex tears of the triangular fibrocartilage complex involving large segments of the ligament and always involving the dorsal periphery. All tears followed the same pattern of disruption of the attachments of two sides of the triangular fibrocartilage complex. We believe our findings will pave the path to further prospective studies in understanding the degree of damage in the triangular fibrocartilage in such devastating injuries and the need for meticulous arthroscopic repair.","PeriodicalId":46757,"journal":{"name":"Journal of Wrist Surgery","volume":"67 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139370755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, case series have been published regarding the use of arthroscopic thermal shrinkage of the capsule in adults. Reports of the use of the technique in children and adolescents are rare, and there are no published case series. <b>Methods</b> In a tertiary hand center for children's hand and wrist conditions, 51 patients were treated with arthroscopy for PMCI between 2014 and 2021. Eighteen out of 51 patients carried additional diagnosis of juvenile idiopathic arthritis (JIA) or a congenital arthritis. Data were collected including range of movement, visual analog scale (VAS) at rest and with load, and grip strength. Data were used to determine the safety and efficacy of this treatment in pediatric and adolescent patients. <b>Results</b> Mean follow-up was 11.9 months. The procedure was well tolerated and no complications were recorded. Range of movement was preserved postoperatively. In all groups VAS scores at rest and with load improved. Those who underwent arthroscopic capsular shrinkage (ACS) had significantly greater improvement in VAS with load, compared with those who underwent arthroscopic synovectomy alone ( <i>p</i> = 0.04). Comparing those treated with underlying JIA versus those without, there was no difference in postoperative range of movement, but there was significantly greater improvement for the non-JIA group in terms of both VAS at rest ( <i>p</i> = 0.02) and VAS with load ( <i>p</i> = 0.02). Those with JIA and hypermobility stabilized postoperatively, and those with JIA with signs of early carpal collapse and no hypermobility achieved improved range of movement, in terms of flexion ( <i>p</i> = 0.02), extension ( <i>p</i> = 0.03), and radial deviation ( <i>p</i> = 0.01). <b>Conclusion</b> ACS is a well-tolerated, safe, and effective procedure for PMCI in children and adolescents. It improves pain and instability at rest and with load, and offers benefit over open synovectomy alone.

All patients suffered DRF, classified using the universal classification system. Two different intervals were developed palmary: the first ulnarly to the flexor carpi radialis tendon for direct visualization of the distal radius and the second one radially to the radial artery for direct visualization of the styloid process. An anatomic volar locking compression plate was applied to all patients. The radial styloid process was fixed and stabilized either with Kirschner-wires or an anatomic plate through the same incision.
