Dorsal extension block pinning is a commonly performed surgical technique for acute bony mallet fingers. However, the treatment of chronic bony mallet finger remains controversial. We investigated the use of dorsal extension block pinning with percutaneous curettage for chronic bony mallet fingers. Seven patients with chronic bony mallet fingers were treated by dorsal extension block pinning with percutaneous curettage. The average age was 17 (range, 12–23) years, and the average time from injury to surgery was 20 (range, 7–49) weeks. Bone union was achieved in all patients. None of the patients experienced pain after bone union. The average loss of distal interphalangeal joint extension was 6 (range, 5–20) degrees, and the average flexion was 59 (range, 40–80) degrees. The Crawford functional score was excellent in three patients, good in two, and fair in two. Dorsal extension block pinning with percutaneous curettage could be a useful treatment for chronic bony mallet fingers.

AbstractThis retrospective study evaluated procedural failures of closed reductions using an extension-block Kirschner wire (K-wire) for bony mallet finger. A total of 132 patients who underwent a closed reduction for bony mallet finger in a procedure using an extension-block K-wire were radiographically assessed. Radiographs were used to evaluate (1) postoperative displacement of the reduction before or after K-wire removal and (2) inaccurate reduction of the fragment immediately after surgery. The causes of procedural failure and bone union were evaluated using radiographs and medical records of the intraoperative findings. Out of 132 patients, 17 with procedural failure were enrolled. Displacement of the reduction before and after K-wire removal occurred in seven and six cases, respectively. Inaccurate reduction immediately after surgery occurred in four cases. The most common cause of procedural failure was inaccurate insertion of the K-wire to fix the distal interphalangeal joint (eight cases) followed by inaccurate insertion of the extension-block pin (five cases). All patients had bone union regardless of the displacement of the reduction or inaccurate reduction of the fragment. Caution should be exercised during the reduction and fixation when an extension-block K-wire is used in a closed reduction procedure.

New Surgical Technique

A new surgical technique is described for the treatment of mallet finger deformity which involves the application of a mini external fixator across the distal interphalangeal joint and resection of a portion of the extensor mechanism. We reviewed 19 patients who were treated with this technique, at a mean follow-up period of 36 (range, 24–48) months. The mean extensor lag was 2° (range, −7° to 13°) and the mean flexion range was 70° (range, 20°–90°).

Abstract Background Closed tendinous mallet finger can be treated non-operatively by extension splinting of the distal interphalangeal joint (DIPJ) for 6 to 8 weeks. However, method of conservative treatment in detail differs among various reports, especially in type of orthosis, duration of full-time immobilization and additional night orthotic wear after full-time immobilization. In our institution, full-time Stack splint is applied with distal interphalangeal joint (DIPJ) in extension for 12 weeks and night orthosis is worn for 4 weeks. Purpose The purpose of this study was to evaluate clinical and functional outcomes of tendinous mallet finger using our treatment protocol. Patients and Methods Between March 2007 and December 2017, patients with tendinous mallet finger who were managed conservatively according to our treatment protocol were retrospectively reviewed. A total of 100 patients (101 cases) were enrolled, including 77 males and 23 females. Extension lag was measured before, soon after treatment, and at the final follow-up. Flexion angle of DIP joint was measured at the final follow-up. Patients were clinically evaluated based on the Crawford classification scale and Abouna & Brown criteria. Results The mean age of patients was 40 years and the mean follow-up was 48 months. The mean extension lag was 28.3 degrees initially and 2.6 degrees at the final follow-up. (p-value < 0.001) Flexion angle at the final follow-up was 68.3 degrees. Based on the Crawford classification scale, 56 % of patients had excellent results, and 25 % of patients had good results. According to Abouna & Brown criteria, 78 % of patients had success results and 7.5 % of patients had improved results. Conclusions Wearing orthosis for up to 16 weeks (12 weeks full time and 4 weeks night orthosis) in the treatment of tendinous mallet finger injuries can achieve satisfying result.

A new splint for the treatment of closed mallet finger injuries is described. This is a modified aluminium-foam (‘Zimmer’) splint, which takes account of the skin circulation at the distal interphalangeal joint, and is specifically designed to alleviate the potential problems which can be seen with the traditional ‘mallet finger’ splints.

A prospective controlled trial of mallet-finger injuries treated by internal fixation or external splintage of the distal interphalangeal joint showed no particular advantages for either method, but suggested that patients presenting after some delay may achieve better results after internal fixation.
