Effect of Wrist Arthroscopy in the Treatment of Triangular Fibrocartilage Complex Injury

Abstract：Objective To evaluate the effect of wrist arthroscopy in the treatment of triangular fibrocartilage complex injury.Methods Twenty-two patients with triangular fibrocartilage complex injury were enrolled in our hospital from January 2013 to June 2016.Among them,there were 16 males(73％) and 6 female (27％) patients with a mean age of (31.5±8.27) (range,22 to 5) years.According to Palmer classification,16 patients had type Ⅰ injury (10 cases of Ⅰ A type,4 cases of Ⅰ B type,1 case of Ⅰ C type,1 case of Ⅰ D type),and 6 cases had type Ⅱ injury (2 cases of type Ⅱ A,1 case of type Ⅱ b,Ⅱ c type 3 cases).The Ⅰ A,Ⅰ D-type TFCC injury patients underwent simple debridement surgery;Ⅰ B,Ⅰ C-type injury patient underwent the suture repair;type Ⅱ TFCC injury patients underwent debridement surgery with cartilage surgery.Wrist activity,wrist pain,grip strength,wrist function score (improved Mayo score) were evaluated.Results All patients were followed up 9～24 months (mean,17.60±5.10 months).The results showed that the wrist pain was improved in 22 patients with postoperative follow-up.The grip strength was improved with the degree of rotational activity (157.05±3.26)°,the radius of the ulcer (39.45 ± 1.60)°,the wrist Joint flexion and extension (126.95 ± 1.65)°.According to improved Mayo score:excellent in 14 cases,good in 6 cases,fair in 2 cases;excellent rate of 90.9％.Conclusion Wrist arthroscopy is a minimally invasive,effective and safe method for diagnosis and treatment of patients with TFCC injury.The follow-up effect is satisfactory and should be used as a routine diagnosis and treatment of ulcer joint pain.
