Abstract

Introduction: Dislocation of metacarpo phalangeal joint of index finger is an uncommon injury encountered in day today practice. Though closed reduction is tried, the head of the metacarpal bone is button holed within capsule- ligamentous attatchments resulting in the need of surgical intervention. In this study, we advocate a percutaneous dorsal approach to reduce the dislocation.
Aim: To evaluate the effectiveness of percutaneous dorsal incision over open surgical intervention in the patients with metacarpophalangeal joint dislocation.
Materials and Methods: This prospective study was done in Thanjavur medical college from 2010-2017 for a period of seven years after getting approval from the ethical committee. Twenty patients with complex MCP joint dislocation were included in the study. Informed and written consent is obtained from the participants. All the patients were subjected to X-ray examination of the hand to assess the bony injuries and joint status. Percutaneous dorsal incision was made to reduce the dislocation. All the patients were followed up for 3 months and the results were analysed.
Results: The final results showed good joint mobility without stiffness in 16 patients, stiffness of the joint in 4 patients and no recurrent dislocations were noted.
Conclusion: Complex dislocation of Metacarpophalangeal joint of index finger which is irreducible by closed manipulation is best approached by percutaneous incision. This technique is easier, simpler with minimal neurovascular injuries. Further clinical evaluation is to be done to assess the effectiveness of this method.
