en جراحی دست / آرنج Hand surgery / Elbow پژوهشی Research Article <div style="text-align: justify;"><strong>Background</strong>: Rotational dislocation of the proximal interphalangeal (PIP) joint is an uncommon but functionally important injury that can be overlooked or treated later, leading to stiffness and disability.<br> <strong>Objectives</strong>: This study aimed to evaluate the long-term clinical and functional outcomes of patients who underwent surgical intervention for rotational dislocation of the PIP joint.<br> <strong>Methods</strong>: This retrospective case series reviewed the medical records of patients treated for PIP rotational dislocation at a tertiary hand surgery center between 2013 and 2024. Eligible patients were contacted for clinical follow-up. Functional assessment included range of motion, grip and pinch strength, pain evaluation using the visual analog scale (VAS), and patient-reported outcomes using the quick disabilities of the arm, shoulder and hand (QuickDASH) and patient-rated wrist and hand evaluation (PRWE) questionnaires. Descriptive statistics were used for analysis.<br> <strong>Results</strong>: Nine patients were included. The mean age was 30.0&plusmn;9.9 years, and the mean interval from injury to surgery was 11.1&plusmn;13.6 days. The mean follow-up duration was 9.0&plusmn;1.5 years. At final follow-up, all patients reported complete pain relief (VAS, 0.0&plusmn;0.0). The mean QuickDASH score was 1.8&plusmn;3.7, and the mean PRWE score was 2.7&plusmn;3.2. Grip strength of the operated hand was comparable to the contralateral side, with no significant difference between sides. Overall patient satisfaction and functional recovery were favorable.<br> <strong>Conclusion</strong>: Surgical treatment of PIP rotational dislocation was associated with excellent long-term pain relief and favorable functional outcomes. Early surgical intervention and restoration of joint congruity may help prevent the stiffness and persistent disability associated with this rare injury.</div> Proximal interphalangeal (PIP) joint, Rotational dislocation, Hand surgery, Surgical outcomes, Quick disabilities of the arm, shoulder and hand dash (QuickDASH), Patient-rated wrist and hand evaluation (PRWE) 127 132 http://jros.iums.ac.ir/browse.php?a_code=A-10-2752-1&slc_lang=en&sid=1 Hooman Shariatzade shariatzadeh_h@hotmail.com 10031947532846009341 10031947532846009341 No Department of Orthopedics, Bone and Joint Reconstruction Research Center, School of Medicine, Iran University of Medical Sciences, Tehran, Iran.
