Minimally Invasive vs Open Approach for First Metatarsophalangeal Joint Arthrodesis: Short Report of Early Results.

BACKGROUND: We aim to compare early surgical results between groups who underwent minimally invasive surgery (MIS) vs open first metatarsophalangeal (MTP) arthrodesis to treat end-stage hallux rigidus. METHODS: We conducted a retrospective cohort review of 65 patients who underwent a first MTP fusion procedure at an academic medical center between 2015 and 2023. Success of fusion was determined radiographically. Postoperative complications were identified through medical record review. RESULTS: Sixty-seven first MTP fusion surgeries (41 open and 26 MIS) were performed on 65 patients with a primary diagnosis of hallux rigidus. Open surgery and MIS groups had similarly high fusion rates: 95% (39/41) and 96% (25/26), respectively (P = .84). We identified no difference in overall complication rates: 20% for open surgery and 23% for MIS (P = .73). CONCLUSION: This retrospective analysis of 67 first MTP arthrodesis procedures showed no significant differences in fusion success or complications in the short term when comparing MIS to open surgery. Further studies are needed to elucidate potential differences between MIS vs open surgery. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Effect of sequential burr passes on minimally invasive akin and first metatarsal dorsiflexion osteotomies.

BACKGROUND: Minimally invasive surgical (MIS) osteotomies are increasing as a surgical option for treating midfoot and forefoot conditions. This study aimed to evaluate the impact of each burr pass on the degree of correction, gap size, and alignment in MIS Akin and first metatarsal dorsiflexion osteotomies (DFO). METHODS: MIS Akin and first metatarsal DFO were performed on ten cadaveric specimens. Fluoroscopic measurements included the metatarsal dorsiflexion angle (MDA), dorsal cortical length (MDCL), first phalangeal medial cortical length (PCML) and proximal to distal phalangeal articular angle (PDPAA). RESULTS: The average decrease in PCML with each burr pass was as follows: 1.53, 1.33, 1.27, 1.23 and 1.13 mm at the 1st to 5th pass, respectively. The MDCL sequentially decreased by 1.80, 1.59, 1.35, 0.75, and 0.60 mm. The MDA consistently decreased, and the PDPAA incrementally became more valgus oriented. CONCLUSION: On average, a first metatarsal dorsal wedge resection of 4.7 mm and first phalangeal medial wedge resection of 2.9 mm was achieved after 3 and 2 burr passes, respectively. This data may aid surgeons determine the optimal number of burr passes required to achieve the desired patient-specific surgical correction.

Effect of sequential burr passes on osteotomy magnitude and calcaneal morphology in minimally invasive Zadek osteotomy.

PURPOSE: This study aimed to evaluate the impact of each burr pass on degree of correction, gap size and calcaneal morphology in MIS Zadek osteotomy. METHODS: MIS Zadek osteotomy was performed on ten cadaveric specimens using a 3.1 mm Shannon burr. After each burr pass, the osteotomy gap was manually closed, and the subsequent burr passes were carried out with the foot held in dorsiflexion, which was repeated five times. Lateral X-rays were taken before and after each burr pass. Two independent reviewers measured the dorsal calcaneal length after each burr passage, as well as changes in several calcaneal parameters including X/Y ratio, Fowler Philip angle, and Böhler angle. RESULTS: The average decrease in dorsal calcaneal cortical length with each burr pass was as follows: 2.6 ± 0.9 mm at the 1st pass, 2.4 ± 1 mm at the 2nd pass, 2 ± 1 mm at the 3rd pass, 1.6 ± 1 mm at the 4th pass, and 1.4 ± 0.7 mm at the 5th pass. The Fowler Philip and Böhler angles consistently decreased while the X/Y ratio consistently increased following each consecutive burr pass. Interobserver reliability analysis demonstrated good agreement for all parameters. CONCLUSION: The results revealed the trends of length and anatomical changes in the calcaneus with each burr pass. On average, a dorsal wedge resection of 10 mm was achieved after 5 burr passes. This data can aid surgeons in determining the optimal number of burr passes required for a particular amount of resection, ensuring the attainment of the desired patient-specific surgical outcome.

Trends in Orthopedic Management of Distal Radius Fractures Among Medicare Beneficiaries From 2019 to 2020: A Claims Analysis.

Purpose: Radius and ulna fractures are among the most common fractures. These fractures are managed through operative or nonsurgical treatment, with varying implications in terms of cost and functional outcome. There are few studies that robustly characterize the management of distal radius fractures (DRFs) in the United States during the COVID-19 pandemic. Furthermore, this has not been studied among the Medicare patient population, who are particularly vulnerable to fragility fractures and COVID-19. The purpose of this study is to analyze the services provided to Medicare beneficiaries both before and during the COVID-19 pandemic to determine how procedure volume was affected in this patient population. Methods: We retrospectively analyzed services using the physician or supplier procedure summary data from the Centers for Medicare and Medicaid Services. All services provided by physicians between January 1, 2019, and December 31, 2020, were included. The data were stratified by US census region using insurance carrier number and pricing locality codes. We also compared data between states that maintained governors affiliated with the Democratic or Republican parties for the duration of the study. Results: There was an overall decrease in claims regarding DRFs management from 2019 to 2020. There was a dramatic decline in procedure volume (-6.3% vs -12.9%). Of all distal radius related claims there was a relative increase in the proportion of operatively managed DRFs in 2020, from 50.2% to 52.0%. The Midwest saw the greatest decline in operatively managed DRFs, whereas the West experienced the smallest per-capita decline across all procedures. After separating the data by party affiliation, it was also found that operative and nonsurgical procedure volumes fell more sharply in states with Democratic governors. Conclusions: This study shows a decrease in DRF procedural volume among Medicare beneficiaries. This data suggests that the operative and nonsurgical management of DRFs may have been affected by pandemic factors such as quarantine guidelines and supply chain or resource limitations. This may assist surgeons and health care systems in predicting how similar crises may affect operative volume. Type of study/level of evidence: Therapeutic IV.

Assessment of Patient Satisfaction and Outcomes After Outpatient Joint Arthroplasty in Academic Medical Centers.

Background: There is limited literature evaluating patient satisfaction and outcomes after outpatient joint arthroplasty procedures in academic medical centers (AMCs). The aims of this study are to determine: (1) patients' desires to repeat their procedures and be discharged on the same day, (2) patient-reported outcome measures (PROMs), (3) time to discharge, (4) readmission rates, and (5) factors that predict PROMs in patients undergoing outpatient joint arthroplasty in AMCs. Methods: A prospective survey was completed by 66 total hip arthroplasty (THA), 35 total knee arthroplasty (TKA), and 180 unicondylar knee arthroplasty (UKA) outpatients who underwent surgery from May 2018 to December 2020 in 2 AMCs. The survey consisted of questions regarding hip or knee PROMs (Hip Disability and Osteoarthritis Outcome Score for Joint Replacement, and Knee Injury and Osteoarthritis Outcome Score for Joint Replacement), satisfaction with outpatient procedures and discharges, and reasons for readmissions. Linear regression analysis was conducted with statistical significance set at P < .05. Results: 100% of THA, 93.8% of TKA, and 93.0% of UKA outpatients stated that they would re-elect to undergo their respective procedure. Furthermore, 94% of THA, 81% of TKA, and 95% of UKA patients stated they would like same-day discharge again. THA, TKA, and UKA patients reported respective mean PROM scores of 94.7, 89.9, and 86.1. Readmission rates were 1.5%, 0.0%, and 0.5%, for THA, TKA, and UKA, respectively. Conclusions: Patients who underwent outpatient joint arthroplasty procedures at 2 AMCs experienced minimal readmissions and reported a high desire to repeat their outpatient procedures.
