Background: In North Carolina, the Strengthen Opioid Misuse Prevention Act of 2017 (STOP Act) went into effect on January 1, 2018, intending to increase oversight over opioid prescriptions. This study compares postoperative narcotic prescription practices following operative fixation of ankle fractures before and after the STOP Act. Methods: This study was a retrospective review of patients 18 years and older who underwent operative fixation of ankle fractures between January 1 and June 30, 2017 (before STOP Act), and between January 1 and June 30, 2018 (after STOP Act). Variables of interest included demographics, amount of opioids prescribed postoperatively, number of prescription refills, and number of pain-related calls or visits to the emergency department (ED) or clinic after surgery. This study assessed 71 patients in the Pre group and 47 patients in the Post group. Results: There was a statistically significant decrease in the average number of postoperative narcotic pills prescribed after the STOP Act (52.7 vs 76.2, P < .001). There was also a statistically significant decrease in the average number of prescription refills (0.6 vs 1.0, P = .037). There were no significant changes in pain-related clinic calls (35.2% Pre vs 34.0% Post, P = .896), pain-related clinic visits ahead of schedule (4.2% Pre vs 6.4% Post, P = .681), or pain-related ED visits (2.8% Pre vs 10.6% Post, P = .113). Conclusion: In the postoperative period after operative fixation of ankle fractures, the volume of narcotic prescriptions decreased after the new legislation, without an associated strain on medical resources. Level of Evidence: Level III, therapeutic, comparative study.

Over the past decade, arthroscopic microfracture has become increasingly popular to treat full-thickness (Outerbridge grade IV) chondral defects of the hip. This procedure borrows marrow stimulation treatment principles and techniques from knee arthroscopy, with similar mixed clinical outcomes that may be more favorable in the short term (

Microfracture of hip chondral lesions has been performed for more than a decade with modified treatment principles and techniques from knee arthroscopy. This note and accompanying video review the pertinent techniques, pearls, and pitfalls of the microfracture procedure in the treatment of hip chondral lesions. After debridement of damaged chondral tissue, the size of the lesion is approximated to determine the number of microfracture holes to create. The working portal may be adjusted based on the site of the lesion. Microfracture picks of different angles are used to ensure perpendicular advancement to a depth of 3 to 4 mm in the subchondral bone. The holes are placed at a gap of approximately 3 to 4 mm. The debris is washed out to obtain open holes connecting the marrow with the articular surface. The microfracture procedure should be performed near the end of the overall procedure to secure the bleeding bone marrow within the joint and prevent washout.

Purpose: Various animal models have been proposed to mimic the pathophysiologic process of intervertebral disc degeneration, a leading cause of back pain. The purpose of this study is to describe a minimally invasive technique via percutaneous needle puncture of the annulus fibrosus in New Zealand white rabbits. Methods: Under fluoroscopic guidance, an 18-gauge spinal needle was inserted 2 cm lateral to the midline spinous process. The needle was slowly advanced at approximately 45° angle until it was adjacent to the L5/L6 disc space. Lateral and anteroposterior views were used to verify correct needle position before advancing into the nucleus pulposus. The rabbits underwent weekly X-rays for 4 weeks to assess disc height index. MRI T2 relaxation was evaluated at week four to assess morphological changes. Discs were histologically graded on a 12-point scale to assess degeneration and compared to discs obtained from uninjured rabbits. Results: There were no complications associated with the percutaneous needle puncture procedure. All animals survived the duration of the experiment. Four weeks after injury, the disc height had progressively narrowed to approximately 50% of baseline. MRI assessment at the 4-week time point demonstrated a mean T2 relaxation time at the L5/L6 level that was 20.9% of the T2 relaxation time at the uninjured L4/L5 disc level ( p < 0.001). Histological analysis demonstrated lamellar disorganization of the annulus and decreased cellularity and proteoglycan content within the injured nucleus compared to uninjured control discs. Conclusion: The present study demonstrated a reliable technique of inducing an annular tear via a percutaneous needle puncture. Compared to open surgical approaches, the percutaneous model produces similar progressive disc degeneration while minimizing harm to the animal subjects. Clinical Relevance: The present study establishes a technique for the introduction of novel therapeutic agents to treat disc degeneration that may translate to future clinical trials.
