Isolated Avulsion Fracture of the Fibular Head: A New Fixation Technique Using a Suture Anchor

Avulsion fracture of flexor digitorum profundus (FDP) tendon is relatively rare fracture at the distal phalangeal base than avulsion fracture of terminal extensor tendon. Terminal extensor avulsion fracture, known as bony mallet finger, could be successfully treated by closed reduction and pinning, such as extension block technique. However, most of FDP avulsion fracture, known as Jersey’s finger, needed open reduction, because of the proximal migration of fracture fragment and difficulty of pin fixation. Up to date, most of FDP avulsion fractures were treated by open reduction and fixation by pull-out suture or suture anchor technique. We report a case of comminuted FDP avulsion fracture, successfully treated by open reduction and mini-plate and screw fixation technique.

This study aimed to present and evaluate a new arthroscopic technique that uses two-point suture fixation for anterior cruciate ligament (ACL) tibial avulsion fractures. A total of 15 patients diagnosed with ACL tibial avulsion fracture underwent arthroscopic suture fixation from November 2018 to October 2019 and were treated using two-point suture fixation. The patients were followed up and evaluated according to Lysholm scores, International Knee Documentation Committee (IKDC) subjective scores, Tegner activity level scales, anterior drawer testing, and KT-1000 arthrometer testing. The mean follow-up period was 18 months (12 to 24). All patients had a negative Lachman test and anterior drawer test at final follow-up and showed the radiological union of avulsion fracture at 12-week postoperative radiograph. The Lysholm score improved significantly postoperatively with a mean score of 94.26±3.63 (87 to 98; p < 0.001). The Tegner score improved significantly postoperatively from 3.61 ±1.37 to 7.14±1.51 (P < 0.001). The KT-1000 measured value decreased significantly postoperatively from 7.3±1.5 to 1.4 ±1.2 (P < 0.001). The IKDC category was abnormal or severely abnormal preoperatively, and all patients improved to normal or nearly normal at final follow-up. Arthroscopic treatment using the two-point suture fixation technique is effective for ACL avulsion fracture and can restore the function and stability of the knee joint.

Pull Out Suture

Avulsion fracture of the volar base of the distal phalanx is a rare injury. Zone 1 flexor tendon injuries can be treated with either internal or external fixation techniques. Pull-out suture repairs are often used for FDP tendon avulsion injuries. However, the pull out suture technique is associated with a number of well documented complications including nail bed injury and pressure necrosis. Despite the variety of techniques available for the repair of acute distal zone 1 flexor tendon injuries, no one technique has proven to be superior to all others. We address our experience with treatment of FDP avulsion injuries using suture anchor and miniscrew. Our technique supplements the suture anchor technique, which often causes a lack of strength, with an additional miniscrew. We introduce two cases of combined method using both suture anchor and miniscrew for treatment of FDP avulsion injuries.
