Abstract：Objective To evaluate the effects of the extension block splint for dorsal fracture-dislocation of the proximal interphalangeal ( PIP ) joint. Methods From September 2009 to September 2013, 48 patients with dorsal fracture-dislocation of the PIP joint were treated with the extension block splint in stages. The long-term functional recovery was evaluated, and the joint range of motion was recorded in the follow-up. The total active movement ( TAM ) examination was performed to assess the objective motion function of the ifnger, and the Visual Analogue Scale ( VAS ) was used to evaluate the subjective satisfaction. Results All the 48 patients were followed up for a mean period of 18 months ( range;4-48 months ). Bone union was achieved in all the cases, and satisfactory joint reduction was obtained. The lfexion and extension of the PIP joint were 110 and 0 degrees respectively. According to the TAM examination, there were 48 excellent cases, and the excellent and good rate was 100%. The VAS score is 9.9 points. Lateral instability was noticed in 4 cases, and the opening was less than 30 degrees. After the treatment of the extension block splint, no obvious lateral instability was found and the opening became less than 15 degrees. There were no complications, except for lateral fusiform swelling. Conclusions The treatment of dorsal fracture-dislocation of the PIP joint with the extension block splint is a simple procedure, with excellent outcomes.
