<strong>Background: </strong>Hemi-hamate arthroplasty, a new attractive method for treatment of unstable Proximal Interphalangeal (PIP) joint fracture-dislocations, offers several advantages over the previous methods. This study was designed to evaluate the clinical and radiological outcome of this procedure.<br>
<strong>Methods:</strong> In this study, 14 patients and 15 fingers with PIP joint fracture-dislocations were evaluated, including 8 acute and 7 chronic injuries. The mean age and follow-up of the patients were 35.3 years and 29.7 months, respectively. The mean PIP joint involvement was 56.6%. Objective assessment of the outcome was performed by joint alignment, motion, stability, and grip and pinch strength. Subjective evaluation of the outcome was performed using the Visual Analogue Scale (VAS) and Disabilities of the Arm, Shoulder, and Hand (DASH) score. Statistical analysis was performed using SPSS for Windows (version 16). Independent sample t test or Mann-Whitney U test were used for statistical comparison of the mean values. A p value of < 0.05 was considered significant.<br>
<strong>Results:</strong> At the final follow-up, 14 out of 15 PIP joints were clinically stable. Grip and pinch strength of the injured hand averaged 87.6% and 88% of contralateral hand, respectively. The mean PIP joint flexion, arch of motion, and flexion contracture were 82.6, 63.6, and 19 degrees, respectively. The mean DASH score was 20.33±21.87 in acute and 7.25±11.71 in the chronic group (p=0.181). The mean VAS was 2.87±2.29 in acute versus 0.42±0.78 in chronic patients (p=0.022). The degenerative joint disease was observed in 5 cases.<br>
<strong>Conclusion:</strong> Although hemi-hamate arthroplasty is a promising method for the reconstruction of severe PIP joint fracture-dislocations, it is associated with minimal functional limitation and high rate of osteoarthritis.<br>
