| Objective To observe the clinical efficacy of percutaneous precise internal fixation under wrist arthroscopy in the treatment of fresh Herbert type B2 scaphoid fractures.Methods The clinical data of 17 patients with fresh Herbert type B2 scaphoid fractures who underwent percutaneous precise internal fixation under wrist arthroscopy in Huangshi Love and Health Hospital from February 2021 to April 2023 were retrospectively analyzed. There were 13 males and 4 females, aged between 18 and 52 years, with an average age of (36.24±16.76) years. All patients underwent surgical treatment within 2 weeks after injury. Percutaneous internal fixation under wrist arthroscopy was performed using hollow compression screws. The use of double screws or Kirschner wires for auxiliary fixation was decided on the basis of intraoperative conditions. The operation time, hospital stay, the number of fluoroscopy attempts, fracture healing time, and the cases requiring two screws (or Kirschner wires) were recorded. Postoperative follow-up at 3, 6, 12 weeks, and every 3 months thereafter included wrist X-rays in the anteroposterior and lateral views to assess fracture healing. Pain was evaluated using the visual analog scale (VAS) at 1 and 3 weeks postoperatively. Wrist function was assessed using the Mayo wrist score and DASH score at 3 and 6 months postoperatively.Results All 17 patients were followed up for an average of 16.7 months (range: 13-24 months). No complications such as internal fixation failure or wound infection were observed postoperatively. All fractures healed, with a healing time of 12-24 weeks (average 18 weeks). VAS scores at 3 weeks postoperatively were lower than 1 week postoperatively, the difference was statistically significant (P<0.05). The Mayo scores and DASH scores at 6 months after surgery were improved than 3 months after surgery, the difference was statistically significant (P<0.05).Conclusion Percutaneous precise internal fixation under wrist arthroscopy for the treatment of fresh Herbert type B2 scaphoid fractures is minimally invasive, simple, safe, and allows for quick postoperative recovery. It is a safe and effective treatment method that deserves further clinical promotion. |
