Post-operative protein supplementation following orthopaedic surgery: A systematic review.

Decreased mechanical loading after orthopaedic surgery predisposes patients to develop muscle atrophy. The purpose of this review was to assess whether the evidence supports oral protein supplementation can help decrease postoperative muscle atrophy and/or improve patient outcomes following orthopaedic surgery. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). PubMed (MEDLINE), Embase, Scopus, and Web of Science were searched for randomized controlled trials that assessed protein or amino acid supplementation in patients undergoing orthopaedic surgery. Two investigators independently conducted the search using relevant Boolean operations. Primary outcomes included functional or physiologic measures of muscle atrophy or strength. Fourteen studies including 611 patients (224 males, 387 females) were analyzed. Three studies evaluated protein supplementation after ACL reconstruction (ACLR), 3 after total hip arthroplasty (THA), 5 after total knee arthroplasty (TKA), and 3 after surgical treatment of hip fracture. Protein supplementation showed beneficial effects across all types of surgery. The primary benefit was a decrease in muscle atrophy compared to placebo as measured by muscle cross sectional area. Multiple authors also demonstrated improved functional measures and quicker achievement of rehabilitation benchmarks. Protein supplementation has beneficial effects on mitigating muscle atrophy in the postoperative period following ACLR, THA, TKA, and surgical treatment of hip fracture. These effects often correlate with improved functional measures and quicker achievement of rehabilitation benchmarks. Further research is needed to evaluate long-term effects of protein supplementation and to establish standardized population-specific regimens that maximize treatment efficacy in the postoperative period.

Rehabilitation and return to sport criteria following surgical treatment of osteochondritis dissecans of the capitellum: a systematic review.

Background: Osteochondritis dissecans (OCD) of the capitellum is a well-described condition that most commonly affects adolescent throwing athletes and gymnasts. There is no gold standard rehabilitation protocol or timing for return to sport (RTS) after surgical management of OCD of the capitellum. Hypothesis/Purpose: The purpose of the study was to identify in the existing literature any criteria used for RTS following surgical treatment of OCD of the capitellum. The hypothesis was that surgeons would utilize length of time rather than functional criteria or performance benchmarks for RTS. Methods: Level 1 to 4 studies evaluating athletes who underwent surgery for OCD of the capitellum with a minimum follow-up of 1-year were included. Studies not describing RTS criteria, including less than 1-year follow-up, non-operative management only, and revision procedures were excluded. Each study was analyzed for RTS criteria, RTS rate, RTS timeline, sport played, level of competition, graft source (if utilized), and postoperative rehabilitation parameters. Assessment of bias and methodological quality was performed using the Coleman methodology score and RTS value assessment. Results: All studies reported a rehabilitation protocol with immobilization followed by bracing with progressive range of motion. RTS rate was 80.9% (233/288). The majority of studies reported using time-based criteria for RTS (11/15). The most commonly reported timeline was 6 months (range: 3-12 months). Conclusion: The overall RTS rate after surgical treatment of capitellar OCD is high with no consensus on RTS criteria. The two most consistent RTS criteria reported in the literature are return of elbow range of motion and healing demonstrated on postoperative imaging. There is a wide range of time to RTS in the literature, which may be sport dependent. Further research is needed to develop functional and performance-based metrics to better standardize RTS criteria and rehabilitation protocols.

A High Incidence of Perineal Post-Related Complications After Hip Arthroscopy Is Self-Reported by Patients in Anonymous Online Forums.

Purpose: To evaluate online, self-reported pudendal nerve or perineal injuries related to the use of a perineal post during hip arthroscopy. Methods: Public posts on Reddit and the Health Organization for Pudendal Education were searched to identify anonymous individuals reporting symptoms of pudendal nerve or perineal injury following hip arthroscopy. Included posts were by any individual with a self-reported history of hip arthroscopy who developed symptoms of pudendal nerve injury or damage to the perineal soft tissues. Demographic information and details about a person's symptoms and concerns were collected from each post. Descriptive statistics were used to analyze the data. Results: Twenty-three online posts reported on a perineal post-related complication following hip arthroscopy. Sex information was available in 16 (70%) posts (8 male, 8 female). Twenty-two posts reported a sensory injury, and 4 posts reported a motor injury with sexual consequences (sexual dysfunction, dyspareunia, impotence). Symptom duration was available in 15 (65%) posts (8 temporary, 7 permanent). Permanent symptoms included paresthesia of the perineum or genitals (7) and sexual complaints (5). Two posts stated they were counseled preoperatively about the possibility of this injury. Zero patients reported that a postless hip arthroscopy alternative was an option made available to them before surgery. Conclusions: A high incidence of permanent pudendal nerve, perineal skin, and genitourinary/sexual complications are self-reported and discussed online by patients who have undergone post-assisted hip arthroscopy. These patients report being uninformed and undereducated about the possibility of sustaining a post-related complication. No patient reported being informed of postless hip arthroscopy preoperatively. Clinical Relevance: Identifying and evaluating self-reported patient information in online medical forums can provide important information about patient experiences and outcomes.

#Scoliosis: an analysis of patient perception of scoliosis on TikTok.

Background: Social media presents an opportunity to analyze popular opinion about patient experiences. Idiopathic scoliosis is a spinal pathology commonly identified in younger patients who are the largest users of social media. Objective: To analyze posts on the social media platform, TikTok, to better understand the scoliotic patient condition. Methods: TikTok posts were searched manually by screening for "#Scoliosis." Variables assessed included number of likes, conveyed tone, gender, activities of daily living, incisional scar, imaging, involved spine level, spinal curvature, pain, formal physical therapy, multiple operations/reoperation, brace use, self-image, mobility, and educational/awareness posts. Number of responses per category were evaluated for the total they represented and the percentage of available posts containing those elements. Odds ratios with 95% confidence intervals were calculated for each collected variable. Results: More posts were positive than negative (P < 0.001) and from female users than male users (P < 0.001). Self-image was the most prevalent subject, with many posts not mentioning activities of daily living, incisional scars, imaging, pain, physical therapy, timing, awareness/education, or involved spine levels. Conclusions: More females post about scoliosis than males, with most posts containing positive self-image-related themes. This may represent a positive public attitude about scoliosis; however, further research is needed.

Do Prophylactic Inferior Vena Cava Filters Affect the Rates of Venous Thromboembolism and Pulmonary Embolism in Patients Undergoing Major Spine Surgery?

STUDY DESIGN: Retrospective Analysis. BACKGROUND: Venous thromboembolism (VTE) represents a significant cause of morbidity and mortality in major spine surgery. Placement of prophylactic inferior vena cava filters (IVCF) in patients undergoing major spine surgery was previously adopted at our institution. This study reports our experience and compares VTE rates between patients with and without preoperative IVCF placement. METHODS: A Retrospective comparative study was conducted on adult patients who underwent IVCF placement and those who did not prior to their spinal fusion procedure, between 2013 and 2016. Thoracolumbar fusions (anterior and/or posterior) of 7 or more levels, spinal osteotomies, and a minimum of a 3-month follow-up were included. Traumatic, oncologic, and cervical pathology were excluded. Primary outcomes measured included the incidence of overall VTE (DVT/PE), death, IVCF related complications, and IVCF retrieval. RESULTS: 386 patients who underwent major spine surgery, 258 met the eligibility criteria. Of those patients, 105 patients (40.7%) had prophylactic IVCF placement. All patients had postoperative SCDs and chemoprophylaxis. The presence of an IVCF was associated with an increased rate of overall VTE (14.3% vs 6.5%, P ≤ .05) and DVT episodes (8.6% vs 2.6%, P = .04). The rate of PE for the IVCF group and non-IVCF group was 8.6% and 4.6%, respectively, which was not statistically significant (P = .32). The all-cause mortality rate overall of 2.3% was statistically similar between both groups (P = 1.0). The IVCF group had higher rates of hematoma/seroma vs the non-IVCF group (12.4% vs 3.9%, P ≤ .05). 99 IVCFs were retrievable designs, and 85% were successfully retrieved. Overall IVCF-related complication rate was 11%. CONCLUSIONS: No statistical difference in PE or mortality rates existed between the IVCF and the control group. Patients with IVCF placement experienced approximately twice the rate of VTE and three times the rate of DVT compared to those without IVCF. The IVCF-related complication rate was 11%. Based on the results of this study, the authors recommend against the routine use of prophylactic IVCFs in adults undergoing major spine surgery. LEVEL OF EVIDENCE: III.

Return to Sport and Performance After Thumb Metacarpophalangeal Joint Collateral Ligament Surgery in the National Basketball Association.

Introduction Basketball players are at increased risk of thumb collateral ligament injury (ulnar collateral ligament (UCL) and radial collateral ligament (RCL)). Methods The National Basketball Association (NBA) players with thumb collateral ligament surgery were identified using publicly available data. Performance statistics, ligament injuries (UCL or RCL), return to sport (RTS) time, laterality, and injury dates were recorded. Cases were matched 1:1 with controls based on age (±1 year), body mass index (BMI), NBA experience (±1 year), and performance statistics prior to the index date. RTS was defined as playing in one NBA game postoperatively. Career longevity was evaluated. Summary statistics were calculated, and Student's t-tests (ɑ = 0.001) were performed. Results All 47 players identified with thumb collateral ligament surgeries returned to sport. Thirty-three players (age: 26.9 ± 3.0) had one year of postoperative NBA experience for performance analysis. Career length (case: 9.6 ± 4.1, control: 9.4 ± 4.3, p > 0.001) was not significantly different from controls (p > 0.001). The same season time to RTS (n = 20) was 7.1 ± 2.4 weeks. Off-season or season-ending surgery (n = 13) RTS time was 28.4 ± 18.7 weeks. Neither thumb collateral ligament (UCL, n = 7; RCL, n = 10; unknown, n = 16) had an identifiable difference between the groups when evaluating career length. Career length, games/season, and performance were not different for players who underwent surgery on their dominant thumb (63.6%, 21/33) compared to controls (p > 0.001). Conclusion RTS rate is high in NBA athletes undergoing thumb collateral ligament surgery. Players do not experience decreased performance or career length due to thumb collateral ligament surgery, regardless of a dominant or non-dominant thumb injury.

Sacral insufficiency fracture after lumbosacral decompression and fusion.

Sacral insufficiency fracture is becoming increasingly recognized as a complication of lumbosacral fusion, due to alteration of spinal biomechanics. Recognition of patient presentation is important because plain films may initially be negative with this complication. This case series of seven sacral insufficiency fractures following lumbosacral fusion characterizes key characteristics of presentation and management for sacral insufficiency fracture following lumbosacral fusion, which does not have a clearly defined algorithm for treatment. These seven fractures presented with initial complaints of back pain, lower extremity radicular symptoms, or a combination of the two. All identified fractures in this series were located below the inferior-most level of the fusion construct. Cross-sectional imaging such as computed tomography or magnetic resonance imaging was utilized in each case to make the diagnosis of sacral insufficiency fracture. Management depends on the patient's presentation, symptoms, and fracture pattern, but treatment options include operative revision surgery and nonoperative modalities such as a standard rehabilitation protocol, lumbar bracing, and bone stimulators with close follow-up.

Acetabular Paralabral Cyst Causing Obturator Nerve Compression in the Setting of Femoroacetabular Impingement Syndrome: A Case Report.

CASE: Large acetabular paralabral cysts can cause compression of the surrounding neurovascular structures leading to sensory and motor deficits. We present a 68-year-old man with obturator nerve denervation from a paralabral cyst secondary to a labral tear associated with femoroacetabular impingement syndrome. Resolution of symptoms and return to full activities were achieved at 3 months and maintained beyond 1 year through open cyst excision, obturator neurolysis, arthroscopic femoral osteoplasty, and labral repair in the same surgical setting. The patient had a successful clinical outcome, with pain and dysfunction resolution. CONCLUSION: Large paralabral cysts may cause obturator nerve compression, which can be successfully treated with open nerve decompression and arthroscopic treatment of labral pathology.

Effects of COVID-19 on Geographical Trends in the Orthopaedic Surgery Residency Match.

Historically, medical students often match within the same geographic location or to an orthopaedic surgery residency program affiliated with their medical school. The objective of this investigation was to determine differences in geographic trends between orthopaedic residents matching before and during the Coronavirus-19 (COVID-19) pandemic. METHODS: This study analyzed 2 groups of orthopaedic residents: Pre-COVID cohort (years 2016-2020) and COVID-impacted cohort (year 2021). A list of accredited orthopaedic surgery residency programs (n = 202) was obtained. Orthopaedic residency program webpages were located (region [n = 4], division [n = 9], state [n = 50]). For each resident, their medical school and year of postgraduate training were recorded. Year 2021 resident information was obtained from the orthopaedic residency program webpages, social media accounts, and medical school match lists. Residency programs affiliated with a medical school were also assigned. Descriptive statistics were performed. Two sample Student t tests with Bonferroni correction applied to p-values (α < 0.05 significant) were performed. RESULTS: There were 4,832 residents analyzed (4,074 in Pre-COVID cohort; 758 in COVID-impacted cohort [758/868 of all positions in 2021 Match]). Statistically significant differences were detected between the COVID-impacted cohort (39.6%, p < 0.001) matching in the same state as their medical school (Pre-COVID 33.1%) and the COVID-impacted cohort (28.0%, p < 0.001) matching to a residency program affiliated with their medical school (Pre-COVID 21.2%). In the COVID-impacted cohort, students who matched in state matched to their home program more frequently (69.3%) compared with the Pre-COVID cohort (60.5%). Geographically, there was a difference in the COVID-impacted cohort (52.5%, p < 0.011) matching in the same division (Pre-COVID 47.5%). No statistically significant differences were identified for residents matching to the same region as their medical school (Pre-COVID 60.1%; COVID-impacted 61%, p = 0.968). CONCLUSION: Residents matching in the same state, in the same division, and to a residency program affiliated with their medical school increased significantly in the COVID-impacted cohort. There was no difference between cohorts matching in the same region as their medical school. Level of Evidence: Observational/Cross-Sectional.

Analysis of Current Orthopedic Surgery Residents and Their Prior Medical Education: Does Medical School Ranking Matter in Orthopedic Surgery Match?

OBJECTIVE: The purpose of this study was to determine the strength of the association between medical school ranking and orthopedic surgery residency ranking using the current cohort of orthopedic surgery residents. DESIGN: We obtained a list of accredited programs from Doximity for orthopedic surgery residency programs and U.S. News & World Report for medical schools. Each orthopedic surgery residency program webpage was evaluated for the presence of an orthopedic surgery residency roster. For each resident, the medical school attended, allopathic or osteopathic degree, and year of post-graduate training was recorded. Orthopedic surgery residency programs and medical schools were assigned to one of four tiers for each based on their respective ranking. Descriptive statistics, Chi squared tests and Pearson residuals were used to analyze the association of orthopedic surgery residency tier and medical school tier. Post-hoc pairwise comparisons were performed utilizing the Bonferroni correction to account for 16 tests, correcting the significance level to p = 0.003. SETTING: 187 orthopedic surgery residency program webpages. PARTICIPANTS: 4123 orthopedic surgery residents. RESULTS: There was a significant association between medical school tier and orthopedic surgery residency tier (X2 [9] = 1214.78, p < 0.001). The post-hoc residual values were statistically significant for 75% (12/16) of tests performed. The majority of Tier 1 orthopedic surgery residents 50.5% (800/1585) attended a Tier 1 medical school. The strongest positive association exists between Tier 1 medical students attending Tier 1 residencies (residual = 23.978, p < 0.001). The strongest negative association with Tier 4 residencies was with Tier 1 medical schools (residual= -15.656, p< 0.001). CONCLUSIONS: Medical school ranking is an important consideration for prospective orthopedic surgery applicants and may become more important with less objective measures of academic performance such as United States Medical Licensing Examination Step 1. LEVEL OF EVIDENCE: Observational.

Scoliosis Following Chest Wall Resection for Tumor With and Without Prophylactic Fixation: Case Series.

Posterior chest wall resection is a complex surgical procedure that involves removing any anatomical structure that surrounds the lungs and pleura, such as the intercostals, ribs, and soft tissues. The etiology of scoliosis that develops after chest wall excision is likely both mechanical and paralytic in nature. We report seven cases of scoliosis following posterior chest wall resection. Our results suggest that the prophylactic treatment of scoliosis after chest wall resection decreases the risk of scoliosis.

Treatment for sacral insufficiency fractures: A systematic review.

Intro: Sacral insufficiency fractures after lumbosacral fusion continue to establish themselves as a rare complication after surgery. The diagnosis can often be missed due to inconclusive imaging and non-specific symptoms. In the literature, the treatment of sacral insufficiency fractures varies from non-operative and conservative management to surgical intervention with lumbopelvic fixation. Methods: We performed a systematic review searching the PubMed database using sacral insufficiency fracture treatment after lumbosacral fusion and sacral insufficiency fracture after posterior spinal instrumentation as keywords. Results: This search strategy identified 32 publications from the PubMed database for literature review. After evaluating the inclusion and exclusion criteria, a total of 17 articles were included in the review. 65% of sacral insufficiency fractures were managed surgically with 35% of patients proceeding with non-operative, conservative management only. Revision surgery always involved sacropelvic fixation which typically led to immediate resolution or reduction of symptoms, with the exception of 2 cases that did not receive adequate reduction of symptoms. Five cases reported failed non-operative management that subsequently responded to revision surgery. Conclusion: Outcomes after non-operative management usually leads to symptom resolution; however has a slower symptom relief time as well as a higher chance of failed treatment. Operative outcomes, generally with a variation of sacropelvic fixation lead to immediate symptom resolution and very rarely failed treatment. Clinicians must always maintain a high index of suspicion of new onset lower back or sacral pain after lumbosacral surgery and order a CT scan to rule out a potential insufficiency fracture. Objectives: The objective of this study was to review the literature to examine treatment options for sacral insufficiency fractures after lumbosacral fusion in order to improve clinical practice and management. This systematic review of the literature regarding treatment of sacral insufficiency fractures will assist clinicians in making the accurate diagnosis and devise a strategic treatment plan for patients with sacral insufficiency fractures after spinal instrumentation.

Bilateral Medial Malleolus Stress Fractures in a High School Athlete Treated With Open Reduction Internal Fixation.

Pediatric medial malleolus stress fracture is a rare pathology and has limited data on management. The authors present a case of bilateral medial malleolus stress fracture treated with operative fixation followed by a course of immobilization and protected weight-bearing.

The Effect of the COVID-19 Pandemic on Orthopaedic Residency Program Social Media Utilization.

The COVID-19 pandemic created an unprecedented challenge for orthopaedic surgery residency applicants when away rotations were canceled and interviews were held virtually. The authors hypothesized that (1) Instagram would have more total social media accounts compared with Twitter or Facebook, (2) most social media accounts on all platforms would be created during 2020, and (3) the average number of Instagram followers would be higher among highly ranked programs. METHODS: A list of Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery residency programs (n = 202) that were ranked by reputation was acquired from Doximity. Public Instagram, Facebook, and Twitter profiles of orthopaedic surgery residency programs were identified through a manual search. Variables assessed on each social media platform were all available summary statistics provided by the social media platform. Instagram accounts were categorized into 5 tiers based on numeric reputation ranking, with 40 programs in each tier (except tier 5 with 42 programs). Descriptive statistics were calculated, and continuous data were presented as mean ± standard deviation. Goodness-of-fit regression values were calculated for observed trends. RESULTS: One-hundred seventy-four social media accounts were identified. There was a higher percentage of Instagram accounts (66.1%) compared with Facebook (13.2%) or Twitter (20.7%). From 2010 to 2020, an exponential increase (R2 = 0.88) of social media accounts was observed during 2020. Instagram profiles (77.2%, 98/115 [95 in 2020, 3 in 2021]) were created after the cancelation of away rotations in May 2020. Instagram profiles had 1,029 ± 522.4 average followers, more than Facebook and Twitter. Tier 1 residency programs had the largest average follower count with 1,462.4 ± 584.3 followers. CONCLUSION: Social media presence increased exponentially during 2020. Instagram was the social media platform with the most accounts. Many Instagram accounts were created during 2020, and most were created after away rotations were canceled during the COVID-19 pandemic. Instagram accounts averaged the most followers. Top tier orthopaedic residency programs had a greater number of accounts and average followers than lower tier programs.

Twenty Five-Year Publication Trends in Foot and Ankle Literature: Improved Methodological Quality and Internationality With Time.

BACKGROUND: Methodological quality and author internationality are increasing in orthopaedic surgery. The purpose of this study was to evaluate the methodological quality and author geography trends from 1994 to 2019 in high-quality foot and ankle journals. METHODS: Analyses of 1,242 foot and ankle publications in Foot and Ankle International, American Journal of Bone and Joint Surgery, and American Journal of Sports Medicine were done for 1994, 1999, 2004, 2009, 2014, and 2019. Articles were classified according to study type, level of evidence (LOE), and author's country of publication. RESULTS: The most common clinical study was therapeutic (65.4). Significant increases were noted in the proportion of therapeutic (P < 0.01) and prognostic (P < 0.01) articles. The average LOE increased from 3.96 ± 1.01 to 3.19 ± 0.97 (P < 0.01). The proportion of Level I (P = 0.29) and level IV articles (P = 0.21) remained constant, level II (P < 0.01) and level III (P < 0.01) articles increased, and level V (P < 0.01) articles decreased. United States authorship decreased from 78.1% in 1994 to 44.8% in 2009, then remained constant through 2019 (P < 0.01). CONCLUSION: This study demonstrated an improvement in LOE of foot and ankle publications across a 25-year period in three high-quality orthopaedic journals. Increasing internationality was also observed.

Limb Occlusion Pressure Versus Standard Pneumatic Tourniquet Pressure in Open Carpal Tunnel Surgery - A Randomized Trial.

INTRODUCTION: Pneumatic tourniquets are used extensively in orthopedic hand/wrist surgery. Complications, while rare, are associated with elevated pressure and duration of tourniquet use. Limb occlusion pressure (LOP) is the minimum tourniquet pressure at which arterial blood flow is restricted. Therefore, we performed a cross-sectional double-blinded randomized control trial to assess if there is a difference in post-operative pain at the surgical and tourniquet site between LOP and standard tourniquet pressure and if there is a difference in post-operative opioid usage. METHODS: A total of 44 patients (Age 60±13, 30 female, 14 male) were randomized into two groups (LOP, 191±14 mmHg | STP, 250 mmHg) of 22 patients controlling for gender (15 female, seven male). The primary outcome was a visual analog scale (VAS) for pain at the tourniquet and surgical sites, recorded for the first two weeks post-operative. Daily pain medication usage was recorded and quantified using oral morphine milligram equivalents (MME). A group-by-time generalized mixed-model ANOVA was used to detect within-group and between group (LOP vs STP) differences in VAS at the surgical and tourniquet sites as well as medication use.  Results: LOP significantly decreased post-operative pain medication usage across the first week (-50%; p<0.05). Both groups had similar VAS pain at the surgery site, but the LOP group had 80% reduced pain at the tourniquet site when averaged across the first post-operative week (p<0.05).  Conclusions: The use of LOP compared to STP elicits reduced post-operative pain at the tourniquet site and reduces post-operative pain medication use in the first post-operative week.
