Background: The objective of this report is to introduce an external-fixation technique using the combination of K-wires and cement.
Methods: From February 2009 to January 2015, 51 patients with shaft fractures of middle phalanges were treated with cemented K-wire fixation. The mean age of patients at surgery was 41 years. The mean time interval from injury to operation was 6±5.78days. Injured digits included index (n=18), long (n=15), ring (n=7), and little (n=11) fingers. Types of fractures were transversal (n=32), short oblique or spiral (n=5), and comminuted (n=14) fractures. Active range of motion of the fingers was measured. Total active motion was scored based on the American Society for Surgery of the Hand. All measurements were compared with those on the opposite fingers. Patients also reported on their satisfaction using the 100-mm visual analogue scale.
Results: At the final follow-ups of 2 years, range of motion of metacarpophalangeal joint, proximal phalangeal joint, and distal interphalangeal joint reached 97%±2.88, 93%±6.65, and 96%±3.22 of the opposite fingers, respectively. Based on Total active motion scoring system, we obtained 36 excellent and 15 good results. Based on VAS, patient satisfaction was 96±3.44.
Conclusions: The cemented K-wire fixation is a reliable technique for the treatment of shaft fractures of middle phalanges. The technique is a minimally invasive procedure with minimal complications.
Level of evidence: Therapeutic study, Level IVa.
