Background and purposeTo investigate the outcome of open versus arthroscopic repair of injuries of the triangular fibrocartilage complex (TFCC).MethodsAn electronic literature search of articles published between January 1, 1985, and May 26, 2016, in PubMed, Embase, and the Cochrane Library was carried out in May 2016 and updated in March and December 2017. Studies comparing open and arthroscopic repair of TFCC injury with a mean follow up of more than 1 year were eligible for inclusion. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist guided the extraction and reporting of data. The methodological quality of the included articles was assessed with the Cochrane Collaboration’s tool for assessing risk of bias. The primary outcome measure was the rate of postoperative distal radioulnar joint (DRUJ) re-instability. Secondary outcome measures were range of motion (ROM), grip strength, residual pain, functional wrist scores and the rates of complications and re-operations.ResultsA total of 868 articles were identified by the electronic search. After duplicate removal and subsequent study selection, a total of two studies were included in this systematic review. The methodological quality of the included articles displayed risks of bias. There was no difference in DRUJ re-instability between open and arthroscopic repair of the TFCC. There were no differences in obtained postoperative ROM, grip strength or values in functional outcome scores, between open and arthroscopic TFCC repair in the two included studies, except for the Disability of the Arm Shoulder and Hand (DASH) questionnaire - in favor of arthroscopic surgery - in one of the included studies.ConclusionsThis systematic review shows comparable results between open and arthroscopic repair of the TFCC, in terms of DRUJ re-instability and functional outcome scores. There is insufficient evidence to recommend one technique over the other in clinical practice. There is an immense lack of comparison studies with high level of evidence in the area of wrist ligament repair and reconstruction, including TFCC-injuries and DRUJ-instability.

Injuries to the scapholunate joint are the most common cause of carpal instability.An isolated injury to the scapholunate ligament may progress to abnormal joint mechanics and degenerative cartilage changes.Treatment for scapholunate instability is aimed at arresting the degenerative process by restoring ligament continuity and normalising carpal kinematics.Early arthroscopic diagnosis of scapholunate injury is mandatory for establishing the prognosis of the injury, as a proper ligament repair is recommended within four to six weeks after trauma.In this review, anatomy, diagnosis and treatment of scapholunate ligament injury and carpal instability are discussed. Recommendations for treatment based on the stage and classification of injury and the degree of instability and arthritic changes are proposed.Cite this article: EFORT Open Rev 2017;2:382–393.

The dorsal scapholunate (SL) ligament may disrupt in variety of ways. Each form of injury requires specific fixation. To investigate the incidence of each type of ligament failure, the records of 45 patients with adequate information, good quality pictures, or videos demonstrating injury characteristics were reviewed. Four types of SL injury were found: type 1 (lateral avulsion from the scaphoid) was the most frequent, present in 19 patients (42%); type 2 (medial avulsion from the lunate) was the least frequent, with 7 cases (16%); type 3 (mid-substance rupture) was found on 9 occasions (20%); and type 4 (partial rupture plus elongation) was observed on 10 occasions (22%). Based on our observations, we submit that an arthroscopically assisted SL capsuloplasty may not be possible in all cases, particularly not when the ligament has avulsed off the bone (60% of the cases), leaving no ligament remnant on one side. Most patients will require ligament reattachment techniques using transosseous sutures, bone anchors, or ligament reconstruction.

Misdiagnosed and maltreated scaphoid fractures filed to the Swedish National Patient Insurance Company (LÖF) 2011–2018 were analyzed in terms of complications and costs for society. All filed claims are database-registered (altogether 200 000 claims since 2000). This database was assessed in June 2019 through injury ICD10-SWE-diagnoses. Demographics, complications, complaints, corrective surgeries and costs were analyzed. The numbers of claims for scaphoid fractures were reviewed and compared with all claims. There was a statistically significant trend towards decreasing numbers of notified scaphoid fracture cases during this time. This is not the case compared with the total annually notified injuries to LÖF during the same time, where we instead can see statistically significant increased numbers. Median age for the 128 patients was 24 years. Men represented 76%. Seventy-eight of the 128 (61%) claims were judged as avoidable, compared with 42% in terms of all notified injuries. Pseudoarthrosis dominated as complication (n  = 71). Total numbers of complications were 117, and 47 of the 78 patients had medical invalidity as a consequence. Up to six secondary corrective surgeries per patient were required. Complications and disabilities were more severe if patients needed more than one surgery. The total costs were calculated to €1 226 193. Level of Evidence: LoE III, Therapeutic.

Objective: Focal cartilage injuries, and posttraumatic osteoarthritis (OA) in the wrist are likely common and a cause of wrist pain. To estimate the incidence of cartilage lesions and to understand the pathomechanisms leading to wrist cartilage injuries and OA, a literature review on the subject was performed combined with a presentation of one of the authors’ own experience. Design: This study includes a literature review of the topic. As a comparison to the review findings, the observations of one of the authors’ consecutive 48 wrist arthroscopies, were assessed. PubMed, Scholar, and Cochrane databases were searched using the keywords “cartilage injury AND wrist AND treatment” and “wrist AND cartilage AND chondral AND osteochondral AND degenerative OA.” :Result A total of 11 articles, including 9 concerning chondral and osteochondral repair and treatment and 2 regarding posttraumatic OA, were retrieved. The cartilage repair treatments used in these articles were drilling, osteochondral autograft, juvenile articular cartilage allograft, and chondrocyte implantation. One article displayed concomitant cartilage injuries in displaced distal radius fractures in 32% of the patients. The review of our findings from a 1-year cohort of wrist arthroscopies showed 17% cartilage injuries. Conclusion: There is a lack of knowledge in current literature on cartilage injuries and treatment, as well as posttraumatic OA in the wrist. Cartilage injuries appear to be common, being found in 17% to 32% of all wrist arthroscopies after trauma, but no guidelines regarding conservative or surgical treatment can be recommended at the moment. Larger prospective comparative studies are needed.
