Parameters, including range of motion (ROM), grip strength, pinch strength, and PIP joint pain assessed via a visual analog scale (VAS). The PIP joint function was evaluated using quick disabilities of the arm, shoulder, and hand (Quick-DASH) questionnaire.<br> <strong>Results</strong>: At a mean follow-up of 18.6 months, the mean PIP ROM was 99&plusmn;5.3 (range 90-110), representing 90.2% of the contralateral side (P=0.31). The mean flexion contracture and extension lag were 6.7&plusmn;3.2&ordm; and 6.3&plusmn;3.1&ordm;, respectively. Patients reported a mean VAS score of 3.3&plusmn;1.5 and a mean quick disabilities of the arm, shoulder, and hand (Quick-DASH) score of 10.8&plusmn;6.1 points. The mean pinch strength of the involved hand averaged 80.4% of the contralateral side (P=0.19), and the mean grip strength averaged 92.29% (P=0.28). All patients achieved union with radiographically concentric joints, and no subluxation or dislocation events occurred during follow-up. Although radiographic evidence of arthritic changes was observed in all patients, these changes were clinically asymptomatic.&nbsp;<br> <strong>Conclusion</strong>: Closed reduction and percutaneous pinning offer a simple, accessible, and minimally invasive technique for managing PIP joint dorsal fracture-dislocations. The observed clinical and radiographic outcomes demonstrate stability and concentricity of the joint, suggesting this technique as a valuable surgical option for such injuries.</span></span></span></div> Proximal interphalangeal (PIP) joint, Dorsal fracture- dislocation, Closed reduction, Percutaneous pinning 225 232 http://jros.iums.ac.ir/browse.php?a_code=A-10-1261-1&slc_lang=en&sid=1 Farid Najdmazhar fnajdmazhar@yahoo.com 10031947532846006888 10031947532846006888 No Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, Iran University of Medical Sciences, Tehran, Iran.
