Abstract:
Objective:To investigate the clinical efficacy of B-mode ultrasound guided percutaneous extensor tendon insertion reconstruction in the treatment of tendinous mallet fingers.Methods:A retrospective analysis was performed on the data of patients with mallet finger deformity admitted to the Department of Hand Surgery of Jinan People’s Hospital from February 2010 to January 2019. Under the guidance of B-mode ultrasound, the extensor tendon was sutured percutaneously with PDS II monofilament suture, pulled to the base of the distal phalanx, which was drilled with a 1.0 mm Kirschner’s wire to reconstruct the insertion of the extensor tendon. The active and passive extension angles of the affected fingers and the wound healing were observed after operation. Evaluation of finger function using Crawford’s method.Results:A total of 58 cases were enrolled, including 48 males and 10 females, aged 20-53 years. 49 patients were followed up for 6 to 15 months after operation, with an average of 11 months, and 9 patients were lost to follow-up. The active extension angle of the affected finger changed from 46.5°±7.2° before operation to 6.4°±0.5° after operation, and the difference was statistically significant before and after operation ( t=38.89, P<0.001). The passive extension angle decreased from 3.2° ±0.3°before operation to 0.9° ±0.2°after operation, and the difference was statistically significant before and after operation ( t=44.65, P<0.001). There were no complications such as exposed knots and skin necrosis. Evaluation by Crawford method: excellent in 29 cases, good in 12 cases, and fair in 8 cases. Conclusions:Percutaneous ultrasound-guided extensor finger tendon insertion reconstruction, minimally invasive surgery, in the treatment of tendon mallet finger function recovered well, and the effect was satisfactory.
