“…Temporary transfixation of the DIP joint may induce transient stiffness, but resolves with active movement over time. In addition to the above aspect, a temporary minimally invasive treatment can counteract the traction of the intrinsic muscles on the distal interphalangeal joint and thus on the bony fragment [ 22 , 32 ]. This leads to prevention of pseudarthrosis and consequently resulting in an elongation of the extensor tendon with an associated loss of function of the distal interphalangeal joint with necessary subsequent operations [ 22 , 33 ].…”

Introduction Mallet fingers are the most common tendon injuries of the hand. Bony avulsion distal finger extensor tendon ruptures causing a mallet finger require special attention and management. In this monocentral study, we analyzed the clinical and individual outcomes succeeding minimal invasive k-wire extension block treatment of bony mallet fingers. Materials and methods In a retrospective study, we sent a self-designed template and a QUICK-DASH score questionnaire to all patients, who were treated because of a bony mallet finger between 2009 and 2022 and fulfilled the inclusion criteria. A total of 244 requests were sent out. 72 (29.5%) patients participated in the study. Forty-five men and twenty-seven women were included. Results 98.7% (n = 75) of the cases were successfully treated. Patients were highly satisfied with the treatment (median 8.0; SD ± 2.9; range 1.0–10.0). Based on the QUICK-DASH score, all patients showed no difficulties in daily life. The extent of avulsion did not influence the outcome. Conclusion We conclude that the minimally invasive treatment of a bony mallet finger should be offered to every patient, because it is safe, fast, and reliable. Thus, we propose to perform extension-block pinning independently of the articular area.
