Abstract:
Midcarpal instability (MCI) is a form of the carpal instability nondissociative pattern and can be differentiated into dorsal, palmar, or extrinsic MCI. Dorsal MCI can frequently be observed in adolescent or adult patients due to trauma or hyperlaxity of the palmar intrinsic carpal ligaments. Clinical stress tests and cinematography are capable to depict the ligamentous instability centered around the capitolunate area. We describe a novel technique which aims to address palmar ligamentous hyperlaxity by plication of the radioscaphocapitate, radiolunotriquetral, and arcuate ligaments, thus closing the so-called space of Poirier. This palmar technique has been used in several cases in isolated form or in conjunction with other concomitant procedures. After the floor of the carpal tunnel and thus the palmar ligaments are exposed and the weak spot meticulously verified, 2 or rarely 3 deep FibreWire pulley sutures are used for capsuloligamentous plication. Among 11 patients, 4 cases (5 operated wrists) with isolated capitolunate capsuloligamentous plication were followed at an average of 2.6 years after surgery. The results were excellent with a mean postoperative Disabilities of the Arm, Shoulder and Hand Score of 9.7 (range, 6.9 to 15.0), mean numerical rating scale of 0 at rest and 1 (range, 0 to 2) during stress. All cases stated that they were very satisfied with the result and all would definitely elect to choose the surgery again. Palmar capsuloligamentous plication has been shown to be a quick, relatively easy and reliable procedure to reduce dorsal MCI in our patient cohort.
