Background
Perilunate dislocations and perilunate fracture dislocations (PLD/PLFDs) are rare injuries of the wrist, with surgical management leading to acceptable functional results.
Purpose
The purpose of this study was to assess the functional outcomes of the patients of our department who were treated with surgical management of PLDs/PLFDs through dorsal approach, as well as to report any complications on their follow-up.
Patients and methods
In this retrospective study, 52 patients with PLD/PLFD, fulfilling the inclusion and exclusion criteria of the study, underwent surgical management of their injury. All patients were followed up at 6 weeks, 12 weeks, 6 months, 1 year postoperatively with radiographic imaging as well as functional scores measured with the modified mayo wrist score and the QuickDASH questionnaire.
Results
The mean postoperative modified Mayo score was 76.8 ± 8.8 and the mean QuickDASH score was 1.52 ± 2.18. Of the 52 cases, 20% had excellent results, 42% had good results, 29% had fair results and 9% had poor results as per the modified Mayo wrist score. No patient signed any symptoms of median nerve neuropathy.
Conclusion
In conclusion, open reduction and internal fixation through dorsal approach is a reliable technique to manage perilunate injuries in spite of radiological evidence of wrist arthritis, as it also provides consistently good results in terms of functional outcomes.
Level of evidence IV
Retrospective case series study.
