Arthroscopically assisted mini-invasive management of perilunate dislocations.

ABSTRACT: Purpose The purpose of this study was to evaluate the outcomes of perilunate dislocations and fracture-dislocations treated with arthroscopically assisted mini-invasive reduction and fixation. Methods Between June 2012 and May 2014, 24 patients who had a dorsal perilunate dislocation or fracture-dislocation were treated with arthroscopically assisted reduction and percutaneous fixation. The mean follow-up was 14.8 months (range 6-32 months). Clinical outcomes were evaluated on the basis of range of motion; grip strength; Mayo Wrist Score; Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire; and Patient-Rated Wrist Evaluation (PRWE) score. Radiographic evaluations included time to scaphoid union, carpal alignments, and any development of arthritis. Results The range of flexion-extension motion of the injured wrist averaged 86% of the values for the contralateral wrist. The grip strength of the injured wrist averaged 83% of the values for the contralateral wrists. The mean QuickDASH score was 6, and the mean PRWE score was 10. According to the Mayo Wrist Scores, overall functional outcomes were rated as excellent in 13 patients (54%), good in 6 (25%), fair in 4 (17%), and poor in 1 (4%). Scaphoid nonunion developed in one patient. Reduction obtained during the operation was maintained within normal ranges in all patients. Arthritis had not developed in any patient at final follow-up. Conclusions Arthroscopically assisted mini-invasive reduction with percutaneous fixation is a reliable and favorable alternative in the treatment of perilunate injuries according to our early follow-up results.Level IV, Therapeutic.

Project description:Background The purpose of this study was to review clinical and radiographic outcomes of perilunate dislocations (PLDs) and fracture-dislocations (PLFDs) treated with external fixation and Kirschner wires (K-wires). Materials and Methods Twenty patients (18 males and 2 females) with a mean age of 38 years (range 18-59) with an acute PLD or PLFD were treated with external fixator and K-wires. There were 12 PLDs and seven transscaphoid and one transstyloid PLFDs. The median time from trauma to operation was 8 hours (range 2-12 hours). Indirect reduction via ligamentotaxis was achieved in 17 patients with a mean age of 38years (range 18-59). There were 12 PLDs and 5 trans-scaphoid PLFDs; however, in three cases (two transscaphoid and one transstyloid PLFDs), indirect reduction failed and an open reduction was required. The intercarpal ligaments were not repaired even after open reduction. Results The mean follow-up was 39 months (range 18-68 months). The flexion-extension range of motion (ROM) and grip strength of the injured wrist averaged 80% and 88%, respectively, of the corresponding values for the contralateral wrists. According to Cooney's scoring system, overall functional outcomes of the 17 patients were rated as excellent in 4 patients, good in 8, fair in 4, and poor in 1. Fifteen patients returned to their former occupations. Two patients with a trans-scaphoid perilunate injury developed nonunion of the scaphoid, and two developed posttraumatic arthritis. Conclusion External fixation plus percutaneous K-wires for the treatment of acute PLDs has satisfactory midterm functional and radiographic outcomes. When successful, this minimally invasive technique is simple and provides restoration of the carpal alignment. It may especially be useful in the polytrauma patient, thanks to its decreased operative time and diminished blood loss, when other emergent surgical procedures may be necessary. An open reduction with possible fixation may be necessary for PLDs and PLFDs, especially in the presence of polytrauma and scaphoid comminution.IV.

Project description:BackgroundAdequate pain control after open esophagectomy is associated with reduced complications, earlier recovery and higher patient satisfaction. While further developing surgical procedures like robot-assisted minimally invasive esophagectomy (RAMIE) it is relevant to adapt postoperative pain management. The primary question of this observational survey was whether one of the two standard treatments, thoracic epidural analgesia (TEA) or intravenous patient-controlled analgesia (PCA), is superior for pain control after RAMIE as the optimal pain management for these patients still remains unclear. Use of additional analgesics, changes in forced expiratory volume in 1 s (FEV1), postoperative complications and duration of intensive care and hospital stay were also analyzed.MethodsThis prospective observational pilot study analyzed 50 patients undergoing RAMIE (postoperative PCA with piritramide or TEA using bupivacaine; each n = 25). Patient reported pain using the numeric rating scale score and differences in FEV1 using a micro spirometer were measured at postoperative day 1, 3 and 7. Additional data of secondary endpoints were collected from patient charts.ResultsKey demographics, comorbidity, clinical and operative variables were equivalently distributed. Patients receiving TEA had lower pain scores and a longer-lasting pain relief. Moreover, TEA was an independent predictive variable for reduced length of hospital stay (HR -3.560 (95% CI: -6.838 to -0.282), p = 0.034).ConclusionsAlthough RAMIE leads to reduced surgical trauma, a less invasive pain therapy with PCA appears to be inferior compared to TEA in case of sufficient postoperative analgesia and length of hospital stay. According to the results of this observational pilot study analgesia with TEA provided better and longer-lasting pain relief compared to PCA. Further randomized controlled trials should be conducted to evaluate the optimal postoperative analgesic treatment for RAMIE.
