Radiographic evaluation included postoperative carpal alignment, scapholunate distance, ulnar translocation, and postoperative arthrosis according to the Kellgren-Lawrence scale. Logistic regression models were used in the study. The analyzed explanatory variables included: type of injury (PLFD\/PLD), Mayfield classification, capsulodesis, repair of intercarpal- and extrinsic ligaments, and number of wrist transfixations. The significance level was set at\n                      <jats:italic>p<\/jats:italic>\n                      \u2009\u2264\u20090.05.

PLFD accounted for 55% of cases. Patients in the PLD group were older at the time of injury (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0031) compared to PLFD.

Midcarpal arthrosis was the most common site of wrist degeneration (58.8%). Ordinal logistic regression indicated that PLFD was associated with a lower risk of midcarpal arthrosis (OR\u2009=\u20090.293,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.04), while a higher number of wrist transfixations increased the risk of advanced arthrosis (OR\u2009=\u20092.427,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.02), The logistic regression model detected a positive effect of the number of wrist transfixations on lunate fovea arthrosis (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.048).
