Retrospective Review of Long-term Outcomes of Patients Undergoing CMC Arthroplasty With Interposition Scaffold.

Background: The treatment of rhizarthritis involves several surgical techniques; among them, bioabsorbable scaffolds have begun to be proposed to avoid the use of other biological tissues or artificial permanent devices. Methods: In this study, we evaluated the long-term outcomes of poly-ld-lactic acid scaffold in interposition arthroplasty in a series of patients treated in our department. Results: Strength, range of motion, and pain improved after the intervention and lasted over the years; nonetheless, most of the radiographs showed a progressive collapse of the first metacarpal. Conclusions: Despite radiological findings, we believe that poly-ld-lactic acid scaffold can be considered a good alternative to traditional trapeziectomy with tendon interposition and suspensionplasty, with long-lasting satisfactory clinical results.

Carpal, cubital or tarsal tunnel syndrome after SARS-CoV-2 infection: A causal link?

COVID-19 is a complex disease with many clinicopathological issues, including respiratory, gastrointestinal, neurological, renal, cutaneous, and coagulative ones; in addition, reactive arthritis has been reported by different authors. Here, we hypothesize that a peripheral microangiopathy involving nerve supply, a viral demyelination, or an immune-mediated irritating antigenic stimulus on synovial sheaths after SARS-CoV-2 infection may all induce a carpal, cubital or tarsal tunnel syndrome of variable entity in genetically predisposed subjects associated with myxoid nerve degeneration.

Modified Viegas dorsal capsuloplasty for chronic partial injury of the scapholunate ligament in young athletes: outcomes at 24 months.

The treatment of chronic scapholunate ligament tears in patients with high demand, such as young athletes, is difficult as traditional techniques are associated with some loss of wrist motion and grip strength. This retrospective investigation studied young athletes (≤20 years old) with chronic scapholunate ligament lesions and a minimum follow-up of 24 months, treated with a modified Viegas dorsal capsuloplasty. Twenty-six young athletes (mean age 17 years) were included. A partial scapholunate ligament tear (Geissler III) was seen in 25 patients. At the last follow-up, a significantly different improvement was seen in all measured parameters and all patients could return to their original competitive activity, within 6 months (range 4-12) after surgery.Level of evidence: IV.
