RESUMEN
Background: Refractory symptoms of carpal tunnel syndrome can persist or reoccur after carpal tunnel release (CTR) surgery in 1% to 25% of patients, with up to 12% of patients requiring secondary surgery. If revision surgery is required, the results are much less successful compared to primary surgery. In this study, we investigated whether cryopreserved human umbilical cord allograft placement during CTR revision surgery improved short- and long-term surgical outcomes. Methods: We conducted a single-center cohort analysis of patients between January 2015 and July 2018 who underwent secondary open revision CTR with umbilical cord allograft for recurrent or persistent compression neuropathy of the median nerve. Surgical outcomes of patients in the study group-reduction of pain, paresthesia, and weakness; complications; and Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores-were compared to the outcomes of controls without umbilical cord allograft use who were operated on by the same surgeon between December 2011 and September 2015. Results: A total of 37 patients underwent CTR with (n=26) and without (n=11) umbilical cord allograft (mean follow-up of 4 years). Following surgery, preoperative symptoms of pain (96% vs 73%, P=0.048) and paresthesia (100% vs 73%, P=0.014) were significantly improved in the patients who received umbilical cord allograft. Mean QuickDASH scores (19.0 vs 23.7, P=0.58) and preoperative weakness (90% vs 67%, P=0.14) were improved in the patients who received umbilical cord allograft but were nonsignificant. Short- and long-term complications were similar between groups (P=0.56, P=0.51, respectively). Conclusion: This study suggests that human umbilical cord allograft placement during open revision CTR is safe and effective for improving long-term symptoms of compressive neuropathy in patients with recurrent carpal tunnel syndrome.
RESUMEN
Orthopedic surgeons frequently encounter medical malpractice claims. The purpose of this study was to assess trends and risk factors in lawsuits brought against orthopedic surgeons using a national legal database. A legal research service was used to search publicly available settlement and verdict reports between 1988 and 2013 by terms "orthopaedic or orthopedic" and "malpractice." Temporal trends were evaluated, and logistic regression was used to identify independent risk factors for case outcomes. A total of 1562 publicly reported malpractice cases brought against orthopedic surgeons, proceeding to trial during a 26-year period, were analyzed. The plaintiffs won 462 (30%) cases, with a mean award of $1.4 million. The frequency of litigation and pay-outs for plaintiffs increased 215% and 280%, respectively, between the first and last 5-year periods. The mean payout for plaintiff-favorable verdicts was highest in pediatrics ($2.6 million), followed by spine ($1.7 million) and oncology ($1.6 million). Fracture fixation (363 cases), arthroplasty (290 cases), and spine (231 cases) were the most commonly litigated procedures, while plaintiffs were most successful for fasciotomy (48%), infection-treating procedures (43%), and carpal tunnel release (37%). When analyzing data by state and region, adjusted for population, northeastern states had a higher frequency of lawsuits. Malpractice liability has increased during the past 3 decades while orthopedic surgeons continue to win most of the cases making it to court. As patients search for medical care via publicly available information, it is important for orthopedic surgeons to understand what aspects of their own practice carry different risks of litigation.
