Chronic fracture-dislocations involving the proximal interphalangeal (PIP) joint are challenging cases. We conducted this study to analyze the outcomes following hemi-hamate autograft reconstruction of such injuries and to compare our results with the existing literature. A retrospective analysis of 21 patients with chronic dorsal PIP fracture-dislocations that were managed with hemi-hamate autograft reconstruction was done. The average articular surface involvement was 64%. The average duration between injury and surgery was 9.4 weeks (range, 6–16). Quick DASH (Disabilities of Shoulder and Hand) scores, VAS (Visual Analog Scale) scores, range of motion of the PIP joints, DIP (distal interphalangeal) joints, and MCP (metacarpophalangeal) joints were measured during serial follow-up visits. Union and graft incorporation was seen in all cases. The average Quick DASH score at four weeks post-surgery was 66 and it improved to eight at one year (p-value
