To evaluate the role of high frequency ultrasonography in diagnosis of acute closed mallet finger injury. 36 patients diagnosed with mallet finger were included in this study. All patients underwent ultrasonography, magnetic resonance imaging(MRI) and X-ray examinations. A new kind of classification of acute mallet finger injury based on ultrasonography findings was described. The difference in terms of extensor tendon injury and bony fragment identification ability among the three types of examinations were described respectively. Either an injury of extensor digital tendon or an avulsion fracture of distal phalangeal base was identified clearly on ultrasonography. Among the 36 cases, avulsion fracture of the distal phalangeal base was found without extensor tendon rupture in Type A, complete rupture of the extensor tendon was found without avulsion fracture in Type B, and contusion of the extensor tendon was found in Type C. Compared with X-ray, ultrasonography and MRI could show the extensor tendon injury clearly. While compared with MRI, ultrasonography and X-ray was more sensitive in showing bony fragment. High frequency ultrasonography could be an accurate, reliable, and non-invasive diagnostic imaging method in diagnosis of acute close mallet finger injury.

“…In addition, when closed reduction and blocking with K-wire are used to treat bony mallet fingers, the K-wire is inserted when the distal phalanx is extremely flexed. Therefore, dorsiflexion and fixation of the IP joint cannot achieve complete returning, resulting in an average of 5° of dorsiflexion loss for most patients [18, 23], but the technique in the present study can completely avoid such complications.…”

“…For bony mallet finger with injury time > 4 weeks, due to the incomplete basal articular surface of the distal phalanx, subluxation to the palmar side is prone to occur because of the continuous traction of the flexor tendon, especially when the avulsed bone block is large. The study by Zhang et al [23] showed that in patients with bony mallet finger, the incidence of subluxation of the DIP joint could be as high as 46%. In the study by Husain et al [11], when the fracture block was > 43% of the phalangette articular surface, there was a high probability of subluxation of the DIP joint.…”

BackgroundThe management of old bony mallet fingers is complicated. The aim of the study is to present a new method of open reduction and compression with double Kirschner wires (K-wires) in treating old bony mallet fingers.MethodsThis was a retrospective analysis of patients with old closed bony mallet fingers treated between June 2013 and December 2016. Complications were observed. The range of motion (ROM) of the DIP joints was measured using a protractor. At the last follow-up, anteroposterior and lateral X-ray of the affected finger was performed, the flatness of the articular surface was scored, and the results were graded using Crawford’s criteria.ResultsSeventeen patients were followed up for 8 (6–19) months. The width of the avulsion fracture block accounted for 25–62% of the articular surface of the distal phalanx. Twelve (70.6%) patients had anterior dislocation of the interphalangeal joint. All patients reported healing at the fracture sites. Healing time was 7.6 ± 2.1(5–13) weeks. All patients had incision healing of I/Class A. Lateral X-ray showed 13 and four patients had excellent and good articular surface flatness, respectively. At the last follow-up, no traumatic arthritis was present. Only one patient developed mild pain after surgery (VAS score of 3). Postoperative ROM was 76.5 ± 10.6° (P = 0.0625 vs. healthy side). At the last follow-up, the angle of loss of dorsiflexion was 0–10° (P < 0.0001 vs. baseline). The flexion angle was 50–90° (P = 0.0625 vs. healthy side).ConclusionsOpen reduction and compression with double K-wires is feasible in treating old bony mallet finger.

“…Wenlong Zhang et al had reported their new fixation technique for mallet fractures of pressing fixation with the end of a K-wire. [21] Dong Hee Kim also have the similar “Fish Hook ” technique for mallet finger. [22] On the basis of their surgical methods, we improved the procedure on some points.…”

“…If the hook pressed the far-end or near-end of the fragment, the fragment will shift or even overturn under the tension. [21] When confirming fracture reset under the screen of the C-arm X-ray, we could tie up the two K-wires around each other using a steel wire at the end. Using our method, the fragment will not shift easily and will hold the fragment anatomically in position to ensure a good fracture union.…”

Rationale: Mallet finger fracture is a common sports-related injury that may lead to the tearing of extensor tendon and protrusion of a bony fragment located at the base of the distal phalanx. We affirmed that the elastic fixation of with two K-wires technique is a good method to deal with Mallet Finger fractures that fractures could gain effective fixation than the conventional treatment method and avoid surgical incision complication Patient concerns: We reported a 33-year-old female patient came to our hospital complaining of mild pain, swelling and her right little finger was deformed because of sport's injury. Diagnosis: Acute mallet finger fracture type IV B according to Doyle classification of mallet injuries. Interventions: We performed an emergency operation for the elastic fixation of the mallet finger fractures with two K-wires. Outcomes: After the surgery, the patient showed functional recovery. No evidence of recurrence was noted 6 months after the operation, and the patient showed no symptoms of sports-related injuries. Lessons: We discuss the clinical diagnosis, treatment, and follow-up of the patient and suggest that elastic fixation with two K-wires is a good method to treat mallet finger fractures.
