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 ⅠA type,4 cases of ⅠB type,1 case of ⅠC type,1 case of ⅠD type),and 6 cases had type Ⅱ injury (2 cases of type ⅡA,1 case of type Ⅱb,Ⅱc type 3 cases).The ⅠA,ⅠD type TFCC injury patients underwent simple debridement surgery;ⅠB,ⅠC 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 followup effect is satisfactory and should be used as a routine diagnosis and treatment of ulcer joint pain.
