“…Therefore, we believe that the old bony mallet finger usually needs to be accurately reduced by open reduction, and removed callus and fibrous tissue of the fracture end and restored fresh bone interface so as to facilitate the fracture healing. Despite the availability of a wide selection of ORIF methods, they often produce inconsistent results in different patients and sometimes even lead to severe complications or aggravation of symptoms [19,20]. The size of the fracture block at the base of the distal phalanx of the patients included in this study was more than one third of the joint surface of the distal phalanx.…”

Background: The management of old bony mallet fingers is complicated. The purpose of this study was to describe direct fixation of fracture fragment with modified double Kirschner wires (K-wires) for treatment of old bony mallet finger, and to evaluate the functional outcomes during long-term follow-up. Methods: Forty-nine patients with old bony mallet finger were enrolled and underwent surgical treatment from August 2014 to January 2021 in our hospital. Patients were divided into two groups according to whether they had undergone triple K-wires fixation or modified double K-wires with a dorsal brace fixation. The operation time, mean number of intraoperative fluoroscopy, bone union time, functional recovery and incidence of complications were monitored. Results: Neither QuickDASH nor visual analogue scale measurement found statistically significant difference between the two groups (P > 0.05). However, the patients that underwent fixation with double K-wires and a dorsal brace required a shorter operation time and fewer intraoperative fluoroscopy, and exhibited a significantly greater mean final active range of the distal interphalangeal joint flexion, compared to those treated with triple K-wires (P < 0.01). Conclusion: Direct fixation of fracture fragment with modified double K-wires was an easy and feasible procedure which could achieve anatomical reduction and stable fixation of the dorsal fracture block of old bony mallet finger with relatively few complications.

“…Lee et al [26] have shown that anatomical reduction can be achieved with the use of two extension block K-wires. Kim et al [27] have performed two extension block pinning in 31 mallet fingers, all of which achieved anatomical reduction with a < 1 mm step-off. However, 12 patients presented with a ≥ 10 extension loss.…”

Purpose This study compared the clinical and radiographic results between extension block pinning (Group A) and percutaneous reduction of the dorsal fragment with a towel clip followed by extension block pinning with direct pin fixation (Group B) for the treatment of mallet fractures. Patients and Methods A total of 69 patients (group A = 34 patients, group B = 35 patients) who underwent operative treatment for mallet fractures from June 2008 to November 2017 with ≥ 6 months post-surgical follow-up were analysed retrospectively. The extent of subluxation of the distal interphalangeal joint, articular involvement of fracture fragment, fracture gap, and articular step-off were examined on plain radiographs before and after surgery. The functional outcomes were evaluated with the Crawford rating system. Results The postoperative step-offs were 0.16 mm in group A and 0.01 mm in group B. Group B had a significantly better anatomical outcome than group A. Five patients in group A had a loss of reduction. Among them, two had malunion and post-traumatic arthritis. Meanwhile, no patients in group B presented with loss of reduction and nonunion. The mean extension lags were 4.2° in group A and 1.6° in group B. However, functional outcome did not differ between the two groups at the final follow-up. Conclusion Fracture reduction using a towel clip and extension block pinning with direct pin insertion for mallet fracture facilitated the anatomical reduction of fragments, and allowed for stable fixation of fragments. Compared with extension block pinning technique, this technique has shown better anatomical results and stability, but not better clinical results.
