Ancillary All-inside Arthroscopic Rapid Positioning Portals for Fracture and Dislocation of the First Carpometacarpal Joint

Discuss the application in "Ancillary All-inside Arthroscopic Rapid Positioning Portals for Fracture and Dislocation of the First Carpometacarpal Joint".

We selected 11 patients who were diagnosed for fracture and dislocation of first carpometacarpal joint who were treated by percutaneous K-wire fixation under arthroscopy in the period of January 2019 to August 2022 .The mean age of the analysed individuals was 37years（range28-57）. During the operation，we used arthroscopic blade to clean the hyperplastic synovial tissue,exfoliated cartilage surface and fracture ends through 1R and 1U portals in the dorsal side of the first carpometacarpal joint with the all-inside arthroscopic rapid positioning technique. The bone fragments was anatomically restored under the pressure of the probe. Fixed the fragments and relocated the first carpometacarpal joint by percutaneous K-wire fixation.

The postoperative follow-up time was 6 ~ 15 months, with an average of 11.5 months. During the follow-up period, all patients were healed with good hand appearance and no residual pain. According to the total range of motion (TAM) system evaluation, 11 cases were excellent.

The application of all-inside arthroscopic rapid positioning portals technique can accurately locate the portal and realign the joint under the arthroscopy. This technique has advantages of good postoperative appearance, micro-traumatic and achieves faster recovery, which reduces the occurrence of traumatic arthritis and is beneficial to clinical development.
