Percutaneous Kirschner-wire fixation followed by an opencast to permit protected daily and sports activities in patients with tendinous mallet finger: a case series at a tertiary hospital in Korea: Hyeon Jun Kim, Ji Woong Kim, Min Kyun Cho, Sung Yoon Jung; J Musculoskelet Trauma 2026;39(4):354-364. Published online October 20, 2026; DOI: https://doi.org/10.12671/jmt.2026.00269

Abstract PDF: Background
Dong-A University Hospital’s protocol for tendinous mallet finger requires 12 weeks of continuous full-time distal interphalangeal (DIP) joint splinting, which may restrict activities and complicate hygiene. This study evaluated the feasibility, short-term safety, and 6-month clinical outcomes of buried Kirschner-wire fixation followed by opencast application.
Methods
This retrospective case series screened 36 patients with mallet finger between January 2024 and October 2025. Twelve met the exclusion criteria, leaving 24 eligible patients; eight elected nonoperative treatment, and 16 chose surgery for acute closed tendinous mallet finger and constituted the study cohort. The DIP joint was fixed in approximately 15° of hyperextension using one or two buried 1.1-mm Kirschner wires. An opencast was applied at 1 week. The wires were routinely removed and active motion was initiated at 8 weeks, followed by a removable brace during outdoor or sports activities for 4 weeks. Outcomes were evaluated at 6 months.
Results
The mean preoperative extension lag was 30.0°. At 6 months, the mean residual extension lag was 1.9°, no flexion loss was observed, and Crawford outcomes were excellent in 62.5% and good in 37.5%. Two superficial pin-site infections resolved with oral antibiotics and local wound care. A separate case of wire loosening with painful subcutaneous prominence was managed with an aluminum splint. All patients resumed daily activities and showering at 1 week, when protected sports were also permitted; exact return dates and activity intensity were not recorded.
Conclusions
Buried Kirschner-wire fixation followed by opencast application may be an option for selected patients who wish to avoid prolonged full-time splinting. The protocol permitted protected activities from week 1 and active DIP motion from week 8; these findings support its feasibility but do not establish earlier return to unrestricted activity. Level of evidence: IV.

Results of the Kapandji Procedure in the AO Type C Distal Radius Fracture in Patients over Age 60: Chul Hong Kim, Sung Soo Kim, Myung Jin Lee, Hyeon Jun Kim, Bo Kun Kim, Young Hoon Lim; J Korean Fract Soc 2012;25(3):191-196. Published online July 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.3.191

Abstract PDF: PURPOSE
To evaluate the clinical and radiologic results of the Kapandji procedure in AO classification type C distal radius fracture patients over 60 years old.
MATERIALS AND METHODS
Twenty-one type C distal radius fracture patients over the age of 60 years who were treated with the Kapandji procedure from June 2004 to June 2009 in our hospital and had a post-operative follow-up period of more than 1 year were enrolled. The volar tilt, radial inclination, and radial length were measured for the radiographic analysis using the modified Lidstrom scoring system about post-operative reduction loss in every follow-up radiogram. The clinical result was assessed with a visual analogue scale (VAS) and Korean Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) score at the last follow-up.
RESULTS
The mean radiologic loss of volar tilt was 1.1degrees and the mean loss of radial length was 2.6 mm and the mean radial inclination loss was 2.7degrees compared with the immediate post-operative period and last follow-up period. The average VAS and DASH scores were 1.4 and 15.9.
CONCLUSION
The radiologic results of closed reduction and percutaneous pinning using the Kapandji technique for distal radius AO type C fracture patients over 60 years of age was not satisfactory. Nevertheless, the clinical results were satisfactory.

Open Reduction and Internal Fixation with AO Calcaneal Plate for Displaced Intra-articular Calcaneal Fracture: Myung Jin Lee, Sung Keun Sohn, Kyu Yeol Lee, Sung Soo Kim, Min Soo Kang, Hyeon Jun Kim, Sang Kyu Sun; J Korean Fract Soc 2010;23(3):303-309. Published online July 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.3.303

Abstract PDF

PURPOSE
To evaluate the surgical outcomes of open reduction and internal fixation of AO calcaneal plate in displaced intra-articular fractures of the calcaneus.
MATERIALS AND METHODS
From January 2004 to July 2007, 25 patients with 27 displaced intra-articular calcaneal fractures were treated by open reduction and internal fixation using the AO calcaneal plate. Preoperative, postoperative evaluations and a follow-up after 1 year were done radiologically by the Bohler angle, Gissane angle, heel height and width among all patients. Their functional status was assessed by means of the Maryland foot score.
RESULTS
The mean Bohler angle, Gissane angle, heel height and width were restored comparing with preoperative data. However, in Sanders type IV, some losses of reduction occurred at 1 year follow-up (p<0.05). The mean Maryland foot scores were 85 points in type II, 82 points in type III and 63 points in type IV. Sanders types significantly affected the clinical results (p<0.05).
CONCLUSION
The AO calcaneal plate fixation using extensile L-shpaed lateral approach shows satisfactory radiologic and clinical results in the treatment of displaced intra-articular calcaneal fractures.

Clinical Outcome of Surgical Treatment for Intra-articular Distal Humerus Fracture: Myung Jin Lee, Hyeon Jun Kim, Sung Keun Sohn, Kyu Yeol Lee, Sung Soo Kim, Chul Hong Kim, Lib Wang, Hyun Woo Sung; J Korean Fract Soc 2010;23(2):201-205.

Abstract PDF

PURPOSE
To evaluate functions of the elbow joint according to surgical approach, time to exercise, and type of fracture after surgical treatment for the intra-articular comminuted fracture of the distal humerus.
MATERIALS AND METHODS
27 patients with the intra-articular comminuted fractures of the distal humerus underwent surgery from March, 2000 to January, 2007. We investigated the surgical approach, time for union, time to exercise and age. We also evaluated postoperative functions of the elbow joint according to the flexion contracture, the range of motion and the Mayo elbow performance score.
RESULTS
The average follow-up period was 37 months and the average time for union was 14 weeks. The average range of flexion was 115 degrees, the average flexion contracture was 10 degrees, and the Mayo elbow performance score with average value of 85 point showed good clinical results. There were no statistically significant differences in functions of the elbow joint according to the operative method and age. However, patients with early postoperative exercise within 6 days showed statistically better outcomes than patients with postoperative exercise after 7 days. Type C1, 2 fractures showed statistically better results than the type C3 fracture.
CONCLUSION
Stable fixation and early exercise are required to prevent postoperative complications and restore functions of the elbow joint with an intra-articular comminuted fracture of the distal humerus.
