Suture Augmentation in Orthopaedic Surgery Offers Improved Time-Zero Biomechanics and Promising Short-Term Clinical Outcomes.

Ligament and tendon ruptures have historically been addressed with varying techniques involving either repair or reconstruction. More recently, the potential biomechanical benefits of suture augmentation (SA), also known as internal brace, have attracted substantial attention and helped renew interest in ligament repair surgery. We evaluated the biomechanical and clinical outcomes of SA-based techniques in the following sports medicine procedures: medial ulnar collateral ligament repair of the elbow, thumb collateral ligament repair, anterior cruciate ligament repair, Achilles' tendon repair, and deltoid ligament repair. Published data on the use of SA to augment repairs of the ulnar collateral ligament, thumb collateral ligament, anterior cruciate ligament, Achilles' tendon, and deltoid ligament repair demonstrate improved time-zero biomechanical and promising short- to mid-term clinical outcomes. However, surgeons must be wary of potential complications, including joint overconstraint, nerve paresthesia, and infection. LEVEL OF EVIDENCE: Level V, expert opinion.

Pickleball- and Paddleball-Related Injuries in the Lower Extremity: Description, Treatment Options, and Return to Play.

Background Pickleball and paddleball are the fastest-growing sports in the United States. However, there are limited studies on the types of lower extremity injuries and treatment options in an outpatient clinic setting. Hypothesis/purpose This study reports the incidence rate, treatments, and return-to-play (RTP) outcomes for patients presenting to a single orthopedic outpatient center with pickleball- and paddleball-related lower extremity injuries. Study design This study is a retrospective case series, with level IV evidence. Methods A database search of our multispecialty electronic medical record (EMR) system from 2015 to 2023 identified 166 patients with outpatient pickleball- and paddleball-related lower extremity injuries. The retrospective data were reviewed for patient demographics, injury type, mechanism of injury, surgical or non-surgical treatment, and return-to-play recommendations. Results We observed that the majority of the patients with pickleball- and paddleball-related injuries in the lower extremities were over 60 years of age, with more males. Additionally, most injuries encountered were ankle sprain/strain from a twisting mechanism, which was treated non-surgically. Additionally, a significant number of patients suffered an Achilles tendon rupture (12.0%), which was treated surgically with an Achilles tendon repair (88.1%), accounting for the most common surgical treatment performed in this study. Of the 166 patients who were seen and treated, 68 (40.9%) returned to play, and 93 (56.3%) were lost to follow-up. Conclusion Most of these injuries were seen in the older population and caused by a sprain or strain due to sudden changes in direction, which were treated non-surgically. The most common surgical treatment was an Achilles tendon repair due to an Achilles tendon rupture. Although a relatively good number of patients were cleared to return to play, some patients were lost to follow-up. Meanwhile, some patients were advised to stop playing pickleball or paddleball due to the severity of their injuries. As this sport continues to rise in popularity and with the incidence rate of lower extremity injuries increasing over time, orthopedic surgeons should be aware of the types of injuries, treatment options, and outcomes, as well as ways to advise patients on prevention. Therefore, further research on the standard treatments and outcomes of pickleball- and paddleball-related injuries in the lower extremities is encouraged.

Evaluation of perioperative care and drivers of cost in geriatric thoracolumbar trauma.

Introduction: As the population of elderly patients continues to rise, the number of these individuals presenting with thoracolumbar trauma is expected to increase. Research question: To investigate thoracolumbar fusion outcomes for patients with vertebral fractures as stratified by decade. Secondarily, we examined the variability of cost across age groups by identifying drivers of cost of care. Materials and methods: We queried the United States Nationwide Inpatient Sample(NIS) for adult patients undergoing spinal fusion for thoracolumbar fractures between 2012 and 2017. Patients were stratified by decade 60-69(sexagenarians), 70-79(septuagenarians) and 80-89(octogenarians). Bivariable analysis followed by multivariable regression was performed to assess independent predictors of length of stay(LOS), hospital cost, and discharge disposition. Results: A total of 2767 patients were included, of which 46%(N = 1268) were sexagenarians, 36% septuagenarians and 18%(N = 502) octogenarians. Septuagenarians and octogenarians had shorter LOS compared to sexagenarians(ß = -0.88 days; p = 0.012) and(ß = -1.78; p < 0.001), respectively. LOS was reduced with posterior approach(-2.46 days[95% CI: 3.73-1.19]; p < 0.001), while Hispanic patients had longer LOS(+1.97 [95% CI: 0.81-3.13]; p < 0.001). Septuagenarians had lower total charges $12,185.70(p = 0.040), while the decrease in charges in octogenarians was more significant, with a decrease of $26,016.30(p < 0.001) as compared to sexagenarians. Posterior approach was associated with a decrease of $24,337.90 in total charges(p = 0.026). Septuagenarians and octogenarians had 1.72 higher odds(p < 0.001) and 4.16 higher odds(p < 0.001), respectively, of discharge to a skilled nursing facility. Discussion and conclusions: Healthcare utilization in geriatric thoracolumbar trauma is complex. Cost reductions in the acute hospital setting may be offset by unaccounted costs after discharge. Further research into this phenomenon and observed racial/ethnic disparities must be pursued.

Comparison of Length of Stay and Discharge Disposition after Short-Segment Lumbar Fusion Surgery at Tertiary Care and Non-Tertiary Care Hospitals: A Propensity Score Matched Analysis.

STUDY DESIGN: A retrospective study. OBJECTIVE: To compare the perioperative and postoperative outcomes among lumbar fusion patients treated at an orthopaedic specialty hospital (OSH), a hybrid community hospital (HCH), and a conventional community hospital in comparison to a tertiary care hospital (TCH). SUMMARY OF BACKGROUND DATA: In spine surgery, strategies to reduce length of stay (LOS) include a myriad of pre-, intra-, and postoperative strategies that require a multidisciplinary infrastructure. The sum of these efforts has led to the creation of orthopedic specialty hospitals and protocols that have been adopted by community hospitals as well. There is a notable lack of information regarding the results of these efforts across different healthcare institution models. METHODS: This was a retrospective study of patients undergoing elective one or two-level lumbar fusion between 2017 and 2022 at a large urban TCH, an OSH, a HCH, and a conventional CH. Data was collected on patient characteristics, demographics, comorbidities, BMI, smoking status, surgical type, surgical levels, surgery duration, hospital length of stay, readmissions, reoperations, and discharge status within a year. Patients across the four surgical settings were matched based on age, BMI, CCI, type of procedure, and number of levels fused. RESULTS: A total of 1435 patients met the inclusion criteria. Length of hospital stay was significantly longer at TCH compared to OSH, HCH, and CH by an average of 1-2 days (P<0.001). 90-day readmissions were higher at TCH compared to OSH (P=0.001). TCH patients also were less likely to be discharged home than OSH and HCH patients (P=0.001 and P=0.016, respectively). No significant differences were noted in 1-year reoperation rates across all hospital models. CONCLUSION: Shorter lengths of stays and more home discharges at the orthopaedic specialty hospital and community hospital settings did not compromise surgical quality or postoperative outcomes.

Preoperative Hounsfield Units Predict Pedicle Screw Loosening in Osteoporotic Patients Following Short Segment Lumbar Fusion.

STUDY DESIGN: Retrospective Cohort. OBJECTIVE: (1) To determine if vertebral HU values obtained from preoperative CT predict postoperative outcomes following 1-3 level lumbar fusion and (2) to investigate whether decreased BMD values determined by HU predict cage subsidence and screw loosening. SUMMARY OF BACKGROUND DATA: In light of suboptimal screening for osteoporosis, vertebral computerized tomography(CT) Hounsfield Units(HU), have been investigated as a surrogate for bone mineral density(BMD). METHODS: In this retrospective study, adult patients who underwent 1-3 level posterior lumbar decompression and fusion(PLDF) or transforaminal lumbar interbody and fusion(TLIF) for degenerative disease between the years 2017-2022 were eligible for inclusion. Demographics and surgical characteristics were collected. Outcomes assessed included 90-day readmissions, 90-day complications, revisions, patient reported outcomes(PROMs), cage subsidence, and screw loosening. Osteoporosis was defined as HU of ≤110 on preoperative CT at L1. RESULTS: We assessed 119 patients with a mean age of 59.1, of whom 80.7% were white and 64.7% were nonsmokers. The majority underwent PLDF(63%) compared to TLIF(37%), with an average of 1.63 levels fused. Osteoporosis was diagnosed in 37.8% of the cohort with a mean HU in the osteoporotic group of 88.4 compared to 169 in non-osteoporotic patients. Although older in age, osteoporotic individuals did not exhibit increased 90-day readmissions, complications, or revisions compared to non-osteoporotic patients. A significant increase in the incidence of screw loosening was noted in the osteoporotic group with no differences observed in subsidence rates. On multivariable linear regression osteoporosis was independently associated with less improvement in visual analog scale(VAS) scores for back pain. CONCLUSIONS: Osteoporosis predicts screw loosening and increased back pain. Clinicians should be advised of the importance of preoperative BMD optimization as part of their surgical planning and the utility of vertebral CT HU as a tool for risk stratification.

Comparative use of ultrasound and radiography for the detection of fractures: a systematic review and narrative synthesis.

Background: Traditionally, X-rays have remained the standard modality for bone fracture diagnosis. However, other diagnostic modalities most notably ultrasound have emerged as a simple, radiation-safe, effective imaging tool to diagnose bone fractures. Despite the advantages, there is a prevalent scarcity of literature recognizing its significance in bone trauma management. This review investigates the effectiveness of ultrasound in the diagnosis of various bone fractures when compared to conventional radiography such as X-rays. Methodology: Electronic databases such as PubMed/Medline, SCOPUS, and Web of Science (WOS) were reviewed for observational studies and review articles from the years 2017-2022 utilizing MESH terminology in a broad term search strategy. The search returned a total of 248 articles. After removal of duplicates, abstract, and full-text screening this systematic review ultimately utilized data from 31 articles. All searches were performed and analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) methodology and were conducted during August 2022. In accordance with the guidelines for assessing the quality of included systematic reviews, we used the AMSTAR 2020, Supplemental Digital Content 2, http://links.lww.com/MS9/A241 (A Measurement Tool to Assess Systematic Reviews) tool to evaluate the methodological quality of the included studies. A data extraction form based on the Cochrane Consumers and Communication Review group's extraction template for quality assessment and evidence synthesis was used for data extraction. The information extracted included details such as author information, database, journal details, type of study, etc. Studies included will be classified into long bones, short bones, pneumatic bones, irregular bones, ankle and knee, stress fractures, hip fractures, POCUS, and others. All included studies considered bias and ethical criteria and provided valuable evidence to answer the research question. Results: The search returned a total of 248 articles, with 192 articles remaining after the removal of duplicates. Primary screening of the title and abstract articles from the database search and additional sources identified 68 relevant articles for full-text screening. This systematic review ultimately used data from 33 articles of the remaining articles we included all of them because they had more than 70% certainty, using the STROBE tool for observational articles, narrative reviews with the ENTREQ guide, and systematic reviews and meta-analyses with the PRISMA guide; however, two articles were excluded at the eligibility stage because of risk of bias. Conclusion: This systematic review provides insightful evidence on safety and effectiveness of ultrasound in diagnosing fractures when compared to the conventional imaging modalities such as X-rays. This shall promote further large-scale, multi-centre research that can eventually guide clinic practice in diagnosing and managing various bone fractures.
