Functional Results of the Management of Carpometacarpal Dislocations of the Long Fingers: A Series of 11 Cases
Journal of Orthopedic Surgery and Techniques(2022)
Abstract
Introduction: Dislocations of the carpometacarpal joint of the fingers are infrequent, accounting for less than 1% of all injuries of the hand.We reported the functional results of 11 cases of CMC dislocations, presented the epidemiological, clinical and management characteristics of these lesions. Patients and methods:We conducted a retrospective study with the prospective collection over 2 years including all the patients, who presented a carpometacarpal dislocation from 2 to 5 rays with a minimum follow-up of 6 months.Quick DASH score and PRWE score were used to assess functional outcomes.Results: Eleven patients were collected, including 9 men and 2 women, mean age was 33-years-old.The dislocation was simple in 3 cases and complex in 8 cases.The displacement of the dislocation was convergent in 10 cases.The dislocation was classified as complete spatular in 4 cases (36.36%), partial spatular in 4 cases as well, and isolated spatular in 3 cases.The definitive treatment was surgical in 8 cases.Complications were noted more in patients who had undergone intramedullary pinning than a direct cross pinning of the metacarpal bases.The average clamping force was 77.27,The average PRWE score was 73.5 with extremes of 20.5 to 90.5 and the average Quick Dash score at 3 months was 24.8 and at 6 months 21.7. Conclusion:CMC dislocations of long fingers are rare lesions.Intramedullary spotting appears to be linked to a rate of complications such as stiffness and chronic pain over the long term.
