Hip Arthroscopy Simulator Training With Immersive Virtual Reality Has Similar Effectiveness to Nonimmersive Virtual Reality

PURPOSE

To (1) compare the efficacy of immersive virtual reality (iVR) to nonimmersive virtual reality (non-iVR) training in hip arthroscopy on procedural and knowledge-based skills acquisition and (2) evaluate the relative cost of each platform.

METHODS

Fourteen orthopaedic surgery residents were randomized to simulation training utilizing an iVR Hip Arthroscopy Simulator (n = 7; PrecisionOS) or non-iVR simulator (n = 7; ArthroS Hip VR; VirtaMed). After training, performance was assessed on a cadaver by 4 expert hip arthroscopists through arthroscopic video review of a diagnostic hip arthroscopy. Performance was assessed using the Objective Structured Assessment of Technical Skills (OSATS) and Arthroscopic Surgery Skill Evaluation Tool (ASSET) scores. A cost analysis was performed using the transfer effectiveness ratio (TER) and a direct cost comparison of iVR to non-iVR.

RESULTS

Demographic characteristics did not differ between treatment arms or by training level, hip arthroscopy experience, or prior simulator use. No significant differences were observed in OSATS and ASSET scores between iVR and non-iVR cohorts (OSATS: iVR 19.6 ± 4.4, non-iVR 21.0 ± 4.1, P = .55; ASSET: iVR 23.7 ± 4.5, non-iVR 25.8 ± 4.8, P = .43). The absolute TER was 0.06 and there was a 132-fold cost difference of iVR to non-iVR.

CONCLUSIONS

Hip arthroscopy simulator training with iVR had similar performance results to non-iVR for technical skill and procedural knowledge acquisition after expert arthroscopic video assessment. The iVR platform had similar effectiveness in transfer of skill compared to non-iVR with a 132 times cost differential. CLINICAL RELEVANCE: Due to the accessibility, effectiveness, and relative affordability, iVR training may be beneficial in the future of safe arthroscopic hip training.

Current Concepts in the Business of Orthopaedics

Practice management within orthopaedic surgery demands a multifaceted skillset including clinical expertise, technical proficiency, and business acumen, yet the latter is rarely taught during orthopaedic training. As the healthcare system evolves in the United States, surgeons continue to face challenges such as decreasing reimbursements, increased regulatory burdens, and potential for practice acquisition. To remain competitive and provide exceptional care for patients, orthopaedic surgeons must cultivate a business-minded approach. This article highlights the growing significance of the business of orthopaedics and offers guidance on ambulatory surgical center ownership models, effective management of ancillary services, the effect of private equity in orthopaedic practice, real estate investment opportunities in medical office buildings, and the importance of brand recognition. By understanding these concepts, orthopaedic surgeons can exercise greater control over their practice's finances while providing quality care for their patients.

Primary Resection of the Ulnar Slip of Flexor Digitorum Superficialis in the Persistently Triggering Patient After A1 Pulley Release

BACKGROUND

The purpose of this study was to determine the occurrence of patients undergoing primary trigger finger release (TFR) that underwent ulnar superficialis slip resection (USSR) for decompression and to determine which digit was most commonly affected.

METHODS

A retrospective chart review was conducted of all cases of open TFR performed by a single surgeon. The following data were obtained: age, sex, laterality, affected digit, and consideration for USSR. All patients failed nonoperative treatment of at least 1 steroid injection. The occurrence of patients who underwent TFR and USSR and which digit(s) most commonly underwent USSR were determined. The average patient age that underwent USSR, frequency by sex, and relative occurrence of USSR in each digit were computed. Statistical calculations were conducted using χ2 analysis (P < .05).

RESULTS

A total of 911 primary open TFRs were performed in 631 patients over a 16-year period. A total of 20 TFRs in 20 patients underwent USSR (2.2%). The long finger was the most commonly affected digit (40%) that required simple decompression. Within all USSR cases, the long finger was the most commonly affected digit. The index finger was the second most affected (30%), and there were no cases in the small finger.

CONCLUSIONS

This study determined the occurrence of primary TFR cases that underwent USSR, with the long finger being the most commonly affected digit. Surgeons may consider this additional procedure to perform a larger decompression than simple A1 pulley release alone.

Midcarpal Instability

Midcarpal instability (MCI) of the wrist represents multiple distinct clinical entities that all have in common abnormal force transmission across the midcarpal joint. This can be asymptomatic but can also result in painful wrist motion, a characteristic catch-up clunk, and symptoms of instability. The carpus is stabilized by numerous extrinsic and intrinsic ligaments. Dynamic joint reactive forces between the proximal and distal carpal rows help create reciprocal motion, which results in smooth, physiologic wrist mechanics. Diagnosis of MCI requires a thorough history, physical examination, and adequate imaging. MCI can be managed nonsurgically with activity modification, physical therapy, specialized orthotics, medications, and corticosteroid injections. A variety of surgical treatment options exists to treat symptomatic MCI. These include arthroscopic thermal capsulorrhaphy, ligament repair or reconstruction, radial osteotomies, and limited radiocarpal or intercarpal fusions. Capsulorrhaphy or ligament repair is favored for mild to moderate cases; osteotomies can be used for the correction of bony deformities contributing to instability, whereas partial wrist arthrodesis is indicated for severe or recurrent instability and fixed deformities.

Elbow Osteochondral Allograft Transplantation and Lateral Ulnar Collateral Ligament Repair with Internal Brace: A Case Report

CASE

A 23-year-old woman with an Osborne-Cotterill lesion and posterolateral rotatory instability (PLRI) of the elbow was treated with osteochondral allograft transplantation (OCA) and lateral ulnar collateral ligament (LUCL) repair with internal brace. Two years after surgery, she reported resolution of pain and returned to all recreational activities. She reported no mechanical symptoms and no episodes of postoperative instability.

CONCLUSION

PLRI can present with an Osborne-Cotterill lesion in addition to LUCL injury. The purpose of this case report was to describe the use of OCA to manage bony defects in the capitellum in addition to LUCL repair for patients with PLRI.

Opioid overprescription in adolescents and young adults undergoing hip arthroscopy

Few studies have examined factors related to the increased consumption of opioids after hip arthroscopy in adolescents and young adults. This study sought to determine prescription patterns following hip arthroscopy in this population, and to determine clinical or surgical factors associated with increased post-operative opioid use. Daily post-operative opioid intake was obtained from pain-control logbooks of adolescents and young adults who underwent hip arthroscopy between January 2017 and 2020. Study outcomes were defined as the median total number of opioid tablets consumed, total days opioids were consumed, mean daily opioid consumption and the ratio of opioids prescribed post-operatively to consumed. Clinical and surgical factors were analyzed to determine any association with opioid consumption. Fifty-eight (20%) patients returned completed logbooks. Most patients (73%) were prescribed 30 oxycodone tablets. The median number of tablets consumed was 7 (range 0–41) over a median duration of 7 days (range 1–22). The median ratio of tablets consumed to prescribed was 20%. Increasing patient age at surgery was associated with increased total number of tablets consumed (r = 0.28, P = 0.04) and to the ratio of tablets consumed to prescribed (r = 0.30, P = 0.03). Patients who were prescribed more than 30 tablets consumed on average 7.8 more tablets than patients prescribed fewer (P = 0.003). Patients who underwent regional anesthesia consumed tablets for longer compared with those who did not (median, 10 versus 4 days; P = 0.03). After undergoing hip arthroscopy, adolescents and young adult patients are commonly overprescribed opioids, consuming on average only one-fifth of the tablets prescribed.
