title: Proximal interphalangeal joint fractures treated with a dynamic external fixator: A multicenter and retrospective study of 88 cases.
abstract: Ligamentotaxis is now a well-established treatment method for proximal interphalangeal (PIP) joint fractures. Despite satisfactory results, the technique is considered complex and the devices cumbersome. The aim of this study was to evaluate a miniaturized dynamic external fixator (Ligamentotaxor(®)) for the management of these fractures. Eighty-six patients with 88 fractures of the PIP joint were treated at 10 European hand surgery centers. The device was applied within eight days of the injury and was removed 40-45 days after the injury. Treatment complications included superficial infection (4 cases), osteoarthritis (1 case), and localized but resolving complex regional pain syndrome (4 cases). The fracture healed in all cases. At final follow-up (mean: 15.2 months), average range of motion was 70° (range: 0-110°). Functional results were comparable between the 10 participating centers. Pain occurred upon exertion in 47% of the patients, 40% were sensitive to weather changes and 26% experienced constant pain. The mean QuickDASH score was 15.7 (range: 11-37) and 83.7% of the patients had no limitations during their daily activities. The results of this series are similar to those reported in other studies of PIP fracture treatment with external fixators. This technique is reliable and reproducible. The device is easy to handle by surgeons and well tolerated by patients. We think that this simple, reliable technique could be relevant for the management of PIP joint fractures.
