Background We have anecdotally noticed a higher rate of trigger fingers (TFs) developing in patients who have undergone carpal tunnel release (CTR). Questions/Objective Is the rate of TFs after CTR greater compared to the nonoperative hand? Is the thumb more commonly involved postoperatively compared with spontaneous TFs? Do particular associated comorbidities increase this risk? Patients and Methods We queried our institutional database for patients who had undergone open CTR during a 2-year period and recorded the development of an ipsilateral TF after a CTR or a contralateral TF in the nonoperative hand. Patient demographics, comorbidities, concurrent initial procedures, time to diagnosis, and finger involvement were recorded. Results A total of 435 patients underwent 556 CTRs during this period. Furthermore, 46 ipsilateral TFs developed in 38 of 556 cases (6.83%) at an average of 228.1 ± 195.7 days after surgery. The thumb was most commonly involved (37.0%) followed by the ring finger (28.3%). The incidence rate of TF in the nonoperative hand during this period was 2.7%, with the ring finger and middle finger most commonly involved (33.3 and 28.6%, respectively). Only history of prior TF in either hand was found to be a significantly associated on Chi-square analysis and multivariable regression (p < 0.001). Conclusion In patients with carpal tunnel syndrome, ipsilateral TFs occurred after 6.83% of CTRs, compared with a rate of 2.7% in the nonoperative hand, making it an important possible outcome to discuss with patients. The thumb was more commonly involved in triggering in the surgical hand compared with the nonoperative hand. Patients with a history of prior TFs in either hand were more likely to develop an ipsilateral TF after CTR. Level of Evidence This is a Level III, retrospective study.

Background: There is variability in access to and utilization of orthopaedic care, particularly for those with Medicaid insurance. One potential contributor is perceived unwillingness of surgeons and hospitals to accept underinsured patients. We used administrative data to examine the payer mix for select inpatient orthopaedic surgical procedures at all hospitals within a single region, hypothesizing that the delivery of orthopaedic surgery to Medicaid beneficiaries varies highly at the hospital level.Methods: Using administrative data, we analyzed inpatient hospitalizations for elective cases (total knee or hip arthroplasty; spinal decompression or fusion) and trauma cases (hip hemiarthroplasty; femoral or tibial and fibular fracture repair) among 22 hospitals in a single region from 2011 to 2016 for patients who were 18 to 64 years of age. The primary outcome was the percentage of each hospital's caseload with Medicaid listed as the primary payer. The secondary outcome measured each hospital's Medicaid percentage against the percentage of Medicaid-insured individuals within 10 miles of the hospital (Medicaid share ratio), using a ratio of 1 as a benchmark. To quantify variation, we calculated a weighted coefficient of variation of the Medicaid share ratio for all cases combined, elective cases only, and trauma cases only.Results: For all cases (n = 19,204), the mean percentage of Medicaid-funded surgical procedures was 7.6% (range, 0.2% to 57.3%). The mean Medicaid share ratio was 1.0 (range, 0.05 to 4.20). Across 22 hospitals, the weighted coefficient of variation for Medicaid share was 69, indicating very high variation. For elective cases alone, the mean percentage of Medicaid-funded surgical procedures was 5.5% (range, 0.2% to 64.6%). The mean Medicaid share ratio was 0.71 (range, 0.05 to 4.73), and the weighted coefficient of variation was 93. For trauma cases alone, Medicaid-funded surgical procedures were 14.7% (range, 0.0% to 35.7%). The mean Medicaid share ratio was 2.0 (range, 0 to 3.93), and the weighted coefficient of variation was 34.Conclusions: Delivery of care was highly variable when benchmarking against the insurance composition of each hospital's surrounding community. Although generalizability to other regions is limited, our findings support previously asserted notions that delivery of orthopaedic care may differ on the basis of socioeconomic markers (such as insurance status). If not addressed, these inequities may exacerbate existing racially and socioeconomically based disparities in care.

Muscle relaxants are commonly prescribed in the United States but may have deleterious side effects that are unrecognized by physicians. Here, we report a 55-year-old Caucasian man who developed pancreatitis and a subsequent hyperosmolar hyperglycemic state after being prescribed tizanidine. The patient had untreated hypertriglyceridemia, unbeknownst to the prescribing physician. While hypertriglyceridemia is a widely understood risk factor for pancreatitis, its incidence with tizanidine is not. As an alpha-2 agonist, tizanidine slows gastrointestinal motility by inhibiting gastrointestinal smooth muscle contraction, which could lead to ileus which occurred in this patient. Alpha-2 agonists further contract the hepato-pancreatic sphincter, which may result in obstruction of pancreatic enzyme flow via the pancreatic duct. This patient’s case of pancreatitis was precipitated by 2 factors: (i) his use of tizanidine and (ii) hypertriglyceridemia. This case demonstrates that patients presenting with severe hypertriglyceridemia, or other potential risk factors for pancreatitis, should not be prescribed tizanidine.
