Local anesthetic with monitored anesthesia care in cephalomedullary nailing of proximal femur fractures.

INTRODUCTION: Proximal femur fractures have high rates of morbidity, mortality, and perioperative complications. Limiting anesthesia, especially in the elderly population, is a priority from a medical perspective. The goal of the current study is to present a technique of using local anesthetic with monitored anesthesia care (MAC) for the fixation of intertrochanteric (IT) femur fractures with cephalomedullary nailing (CMN), provide early clinical results in a small series of patients, and evaluate the safety, efficiency, and anesthetic efficacy of our technique. HYPOTHESIS: The use of only local anesthetic with MAC for the fixation of IT fractures is safe and leads to decreased operative times when compared to spinal and general anesthesia. MATERIALS AND METHODS: Patients undergoing cephalomedullary nailing (CMN) with a long nail for IT femur fractures by a single surgeon from January 2020 to June 2021 were identified retrospectively from a prospectively-collected patient registry. Patient demographics, operative time, length of hospital stay, perioperative medication use, and complications were collected. Analysis of variance, Chi2, linear regression, and two-sampled T-tests were performed to analyze potential differences between the local anesthesia group and the general or spinal anesthesia group. RESULTS: Thirty-seven patients were identified. Eleven patients underwent CMN using local anesthesia with MAC, 11 using spinal anesthesia, and 15 using general anesthesia. The local anesthesia group demonstrated significantly lower operating room times and anesthesia induction to incision time compared to other anesthesia techniques. The local anesthesia group also trended towards less need for vasopressors during surgery and less postoperative delirium. No differences were identified in intraoperative narcotic use, complications, patient mortality, or hospital readmissions. CONCLUSIONS: Local anesthesia with MAC for the treatment of IT fractures with CMN was associated with decreased operating room times and had similar complication rates including blood transfusions, readmissions, and mortalities, when compared to spinal and general anesthesia. LEVEL OF EVIDENCE: III, therapeutic.

Posterior Cruciate Ligament and Patellar Tendon Can Predict Anterior Cruciate Ligament Size for Planning During ACL Reconstruction in Pediatric Patients.

Purpose: To establish correlations between the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and patellar tendon in normal pediatric knees to inform surgical planning for ACL reconstruction graft size. Methods: Magnetic resonance imaging scans of patients ages 8 to 18 years were assessed. Measurements included ACL and PCL length, thickness, and width, and ACL footprint thickness and width at the tibial insertion. Interrater reliability was assessed with a random set of 25 patients. Pearson correlation coefficients were used to assess the correlation between ACL, PCL, and patellar tendon measurements. Linear regression models were used to test whether the relationships differed by sex or age. Results: Magnetic resonance imaging scans of 540 patients were assessed. Interrater reliability was high for all measurements except PCL thickness at midsubstance. Sample equations for estimating ACL size are as follows: ACL length = 22.61 + 1.55∗PCL origin width (R2 = 0.46; 8- to 11-year-old male patients), ACL length = 12.37 + 0.58∗PCL length + 2.29∗PCL origin thickness - 0.90∗PCL insertion width (R2 = 0.68; 8- to 11-year-old female patients), ACL midsubstance thickness = 4.95 + 0.25∗PCL midsubstance thickness + 0.04∗PCL insertion thickness - 0.08∗PCL insertion width (R2 = 0.12; 12- to 18-year-old male patients), and ACL midsubstance width = 0.57 + 0.23∗PCL midsubstance thickness + 0.07∗PCL midsubstance width + 0.16∗PCL insertion width (R2 = 0.24; 12- to 18-year-old female patients). Conclusions: We found correlations between ACL, PCL, and patellar tendon measurements that can be used to create equations that predict ACL size in various dimensions based on PCL and patellar tendon measurements. Clinical Relevance: There is a lack of consensus on the ideal ACL graft diameter for pediatric ACL reconstruction. The findings from this study can assist orthopaedic surgeons to individualize ACL graft size for specific patients.

Variability in Hand Surgery Training Among Plastic and Orthopaedic Surgery Residents.

BACKGROUND: A career in hand surgery in the United States requires a 1-year fellowship after residency training. Different residency specialty programs may vary in case volume. The purpose of this study was to characterize variation in hand surgery training within and between orthopaedic and plastic surgery residents. METHODS: Publicly available hand surgery case logs for graduating orthopaedic and plastic surgery residents during the 2010 to 2011 to 2018 to 2019 academic years were obtained through the Accreditation Council of Graduate Medical Education. Student t-tests were used to compare mean case volumes among several categories between plastic surgery (PRS) and orthopaedic surgery (OS) residents. Intraspecialty variation was assessed by comparing the 90th and 10th percentiles in each category. RESULTS: A total of 6,254 orthopaedic and 1,070 plastic surgery graduating residents were included. The mean hand surgery case volume for orthopaedic residents (OS 247.0) was significantly lower than that for plastic surgery residents (PRS 412.0) (P < 0.0001). Orthopaedic residents performed more trauma cases (OS 133.2, PRS 54.5; P < 0.0001) but fewer nerve repairs (OS 3.3, PRS 28.5 P < 0.0001) and amputations (OS 6.4, PRS 15.8; P < 0.0001). Nerve decompression case volumes were similar between the two specialties (OS 50.2, PRS 47.3; P = 0.34). Case volumes among orthopaedic residents varied considerably in amputations and among plastic surgery residents in replantation/revascularization procedures. CONCLUSIONS: Orthopaedic surgery residents performed significantly more trauma cases than plastic surgery residents did, but fewer overall cases, nerve repairs, and amputations, while nerve decompression volumes were similar between specialties. This information may help inform residency and fellowship directors regarding areas of potential training deficiency.

Treatment modalities and outcomes following acetabular fractures in the elderly: a systematic review.

PURPOSE: The treatment of geriatric acetabular fractures remains controversial. Treatment options include nonoperative management, open reduction and internal fixation (ORIF), total hip arthroplasty (THA) with or without internal fixation, and closed reduction with percutaneous pinning (CRPP). There is currently no consensus on the optimal treatment strategy for geriatric patients with acetabular fractures. The purpose of this study is to compare adverse event rates, functional and radiographic outcomes, and intraoperative results between the various treatment modalities in order to help guide surgical decision making. METHODS: We performed a systematic review (registration number CRD42019124624) of observational and comparative studies including patients aged ≥ 55 with acetabular fractures. RESULTS: Thirty-eight studies including 3,928 patients with a mean age of 72.6 years (range 55-99 years) and a mean follow-up duration of 29.4 months met our eligibility criteria. The pooled mortality rate of all patients was 21.6% (95% confidence interval [CI] 20.9-22.4%) with a mean time to mortality of 12.6 months, and the pooled non-fatal complication rate was 24.7% (95% CI 23.9-25.5%). Patients treated with ORIF had a significantly higher non-fatal complication rate than those treated with ORIF + THA, THA alone, CRPP, or nonoperative management (odds ratios [ORs] 1.87, 2.24, 2.15, and 4.48, respectively; p < 0.01). Patients that underwent ORIF were significantly less likely to undergo subsequent THA than these treated with CRPP (OR 0.49, 95% CI 0.32-0.77) but were more likely to require THA than patients treated nonoperatively (OR 6.81, 95% CI 4.63-10.02). CONCLUSION: Elderly patients with acetabular fractures tend to have favorable functional outcomes but suffer from high rates of mortality and complications. In patients treated with internal or percutaneous fixation, there was a high rate of conversion to THA. When determining surgical treatment in this population, THA alone or concurrent with ORIF should be considered given the significantly lower rate of non-fatal complications and similar mortality rate. Nonoperative management remains a viable option and was associated with the lowest non-fatal complication rate.

The Impact of a Resident's Sense of Control on Burnout in Orthopaedic Surgery Residency.

¼: Physician burnout is a barrier to the patient-centered approach to health care. ¼: One of the driving factors of resident burnout is the decreased level of control that residents have over their everyday lives. ¼: Providing residents with a sense of control over their lives and their jobs increases job satisfaction and leads to a decrease in reports of negative effects on health, rest, participation in extracurricular activities, and time with family.

Psychological and Social Components of Recovery Following Anterior Cruciate Ligament Reconstruction in Young Athletes: A Narrative Review.

Anterior cruciate ligament (ACL) rupture is a common injury in young athletes. To restore knee stability and function, patients often undergo ACL reconstruction (ACLR). Historically, there has been a focus in this population on the epidemiology of ACL injury, the technical aspects of ACL reconstruction, and post-operative functional outcomes. Although increasingly recognized as an important aspect in recovery, there remains limited literature examining the psychological aspects of post-operative rehabilitation and return to play following youth ACL reconstruction. Despite technical surgical successes and well-designed rehabilitation programs, many athletes never reach their preinjury athletic performance level and some may never return to their primary sport. This suggests that other factors may influence recovery, and indeed this has been documented in the adult literature. In addition to restoration of functional strength and stability, psychological and social factors play an important role in the recovery and overall outcome of ACL injuries in the pediatric population. Factors such as psychological readiness to return-to-play (RTP), motivation, mood disturbance, locus of control, recovery expectations, fear of reinjury, and self-esteem are correlated to the RTP potential of the young athlete. A better understanding of these concepts may help to maximize young patients' outcomes after ACL reconstruction. The purpose of this article is to perform a narrative review of the current literature addressing psychosocial factors associated with recovery after ACL injury and subsequent reconstruction in young athletes. Our goal is to provide a resource for clinicians treating youth ACL injuries to help identify patients with maladaptive psychological responses after injury and encourage a multidisciplinary approach when treating young athletes with an ACL rupture.

Factors Associated with Development of Traumatic Acute Compartment Syndrome: A Systematic Review and Meta-analysis.

BACKGROUND: Acute compartment syndrome (ACS) is a devastating condition, further aggravated by delayed diagnosis. Since ACS is a clinical diagnosis, identification of risk factors for individual patients may help with earlier detection. This study aims to identify the risk factors associated with the development of ACS of the extremities. METHODS: We performed a systematic review and meta-analysis of studies with adult patients at risk for and with traumatic ACS of the extremity. Non-traumatic, chronic exertional, vascular and abdominal compartment syndrome were excluded. Technical reports, biomechanical studies, abstracts, studies of non-human subjects, non-English studies, and studies with less than five subjects were excluded. Meta-analysis was performed on a subset of studies including a control group. We addressed cases of substantial heterogeneity among the studies with subgroup analysis, and whenever heterogeneity remained significant, we employed random effect meta-analysis for the data pooling. The study protocol has been registered in PROSPERO (ID = CRD42019126603). RESULTS: There were 19 studies with 48,887 patients investigating risk factors of traumatic ACS. Of these, there were 1,716 patients with the diagnosis of traumatic ACS. Fourteen studies (46,300 controls and 1,358 ACS patients) qualified for meta-analysis. Male to female ratio was 5.5 with an average age of 36 years. Factors that were significantly associated with the development of ACS were: age 18-64 (OR: 1.34, 95% CI: 1.07-1.68), male (OR: 2.18, 95% CI: 1.53-3.10), gunshot wound with fracture and vascular injury (OR: 12.5, 95% CI: 5.69-27.46), combined forefoot and midfoot injury (OR: 3.3, 95% CI: 2.39-4.57), injury severity score (ISS) 0-9 (OR: 1.58, 95% CI: 1.27-1.97), OTA/AO type C fractures (OR: 2.75, 95% CI: 1.04-7.28), vascular injury (OR: 9.05, 95% CI: 6.69-12.26), and high-energy trauma (OR: 3.10, 95% CI: 1.60-5.82). Factors such as tibia fracture and crush injury were reported but were not included in quantitative analysis, due to lack of control groups and/or only one study qualifying for meta-analysis. CONCLUSION: This study reports on the current significant risk factors for developing traumatic ACS. The most common risk factors included age, sex, gunshot wound with a vascular injury, OTA/AO fracture type C and high-energy trauma.

Anterior Cruciate Ligament Reconstruction Graft Technique Reliably Yields Grafts With 8.0-mm Diameter or Larger.

The significance of graft diameter in anterior cruciate ligament reconstruction (ACLR) with soft tissue grafts is well established, with a minimum graft diameter of 8.0 mm associated with lower rates of revision surgery. Consistently achieving grafts that meet or exceed the ideal diameter of 8.0 mm is still a concern with traditional tibial screw fixation, even with quadrupled hamstring autografts. The authors hypothesized that following a simple intraoperative algorithm selectively incorporating the gracilis tendon in an 8-stranded construct for all-inside ACLR with suspensory fixation on both ends of the graft would consistently achieve graft diameters of 8.0 mm or larger by allowing more of the graft material to contribute to increased diameter instead of increased length for screw fixation, with no allograft tissue required. A total of 113 eligible cases were identified, including 70 male patients and 43 female patients (mean±SD age, 25.92±6.47 years; range, 14-49 years). All 113 grafts (100%) were at least 8.0 mm in diameter. There were 8 grafts that were 8.0 mm. Overall mean±SD graft diameter was 9.32±0.71 mm (median, 9.5 mm; range, 8.0-11.0 mm). There were no cases in which allograft tissue was needed to increase graft size. An analysis of 113 cases of all-inside hamstring autograft ACLR with dual suspensory fixation showed that a graft diameter of at least 8.0 mm was achieved in every case, without the use of allograft tissue. These results suggest that this technique for ACLR is reliable in producing grafts that meet or exceed the recommended minimum diameter of 8.0 mm. [Orthopedics. 2021;44(4):e539-e545.].

Comparison of surgical and non-surgical treatments for 3- and 4-part proximal humerus fractures: A network meta-analysis.

INTRODUCTION: Common treatment strategies for proximal humerus fractures include non-surgical treatment, open reduction internal fixation, hemiarthroplasty, and reverse total shoulder arthroplasty. There is currently no consensus regarding the superiority of any one surgical strategy. We used network meta-analysis of randomized controlled trials to determine the most successful treatment for proximal humerus fractures. METHODS: MEDLINE, EMBASE, Web of Science, and Cochrane Central electronic databases were searched for randomized controlled trials comparing 3- and 4-part proximal humerus fracture treatments. Data extraction included the mean and standard deviation of clinical outcomes (Constant, DASH), adverse events, and additional surgery rates. Standard Mean Difference was used to compare clinical outcome scores, and pooled risk ratios were used to compare adverse events and additional surgeries. RESULTS: Eight randomized controlled trials were included for network meta-analysis. Non-surgical treatment was associated with a lower rate of additional surgery and adverse events compared to open reduction internal fixation. Reverse total shoulder arthroplasty resulted in fewer adverse events and a better clinical outcome score than hemiarthroplasty. Non-surgical treatment produced similar clinical scores, adverse event rates, and additional surgery rates to hemiarthroplasty and reverse total shoulder arthroplasty. CONCLUSION: Non-surgical treatment results in fewer complications and additional surgeries compared to open reduction internal fixation. Preliminary data supports reverse total shoulder arthroplasty over hemiarthroplasty, but more evidence is needed to strengthen this conclusion.

Risk factors for developing acute compartment syndrome in the pediatric population: a systematic review and meta-analysis.

PURPOSE: Acute compartment syndrome (ACS) is often difficult to diagnose in pediatric patients due to their erratic symptomatology. Therefore, it is of paramount importance to identify at-risk patients to facilitate a prompt diagnosis. This study aims to identify risk factors for the development of ACS in the pediatric population. METHODS: We included studies comprised of pediatric patients with traumatic ACS. We excluded studies evaluating compartment syndrome secondary to exertion, vascular insult, abdominal processes, burns, and snake bites. Heterogeneity was addressed by subgroup analysis, and whenever it remained significant, we utilized a random-effects meta-analysis for data pooling. The protocol has been registered at PROSPERO (ID = CRD42019126603). RESULTS: We included nine studies with 380,411 patients, of which 1144 patients were diagnosed with traumatic ACS. The average age was 10 years old, and 67% of patients were male. Factors that were significantly associated with ACS were: open radius/ulna fractures (OR 3.56 CI 1.52-8.33, p = 0.003), high-energy trauma (OR 3.51 CI 1.71-7.21, p = 0.001), humerus fractures occurring concurrently with forearm fractures (OR 3.49 CI 1.87-6.52, p < 0.001), open tibia fractures (OR 2.29 CI 1.47-3.55, p < 0.001), and male gender (OR 2.06 CI 1.70-2.51, p < 0.001). CONCLUSION: In the present study, open fractures, high-energy trauma, concurrent humerus and forearm fractures, and male gender significantly increased the risk of developing ACS in the pediatric population. Clinicians should raise their suspicion for ACS when one or multiple of these factors are present in the right clinical context. TYPE OF STUDY: Systematic review and meta-analysis. LEVEL OF EVIDENCE: III.

Carpal Tunnel Release Surgery- A Systematic Review of Open and Endoscopic Approaches.

CONTEXT: Carpal tunnel syndrome (CTS) is the most frequent peripheral compression-induced neuropathy observed in patients worldwide. Surgery is necessary when conservative treatments fail and severe symptoms persist. Traditional Open carpal tunnel release (OCTR) with visualization of carpal tunnel is considered the gold standard for decompression. However, Endoscopic carpal tunnel release (ECTR), a less invasive technique than OCTR is emerging as a standard of care in recent years. EVIDENCE ACQUISITION: Criteria for this systematic review were derived from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two review authors searched PubMed, MEDLINE, and the Cochrane Database in May 2018 using the following MeSH terms from 1993-2016: 'carpal tunnel syndrome,' 'median nerve neuropathy,' 'endoscopic carpal tunnel release,' 'endoscopic surgery,' 'open carpal tunnel release,' 'open surgery,' and 'carpal tunnel surgery.' Additional sources, including Google Scholar, were added. Also, based on bibliographies and consultation with experts, appropriate publications were identified. The primary outcome measure was pain relief. RESULTS: For this analysis, 27 studies met inclusion criteria. Results indicate that ECTR produced superior post-operative pain outcomes during short-term follow-up. Of the studies meeting inclusion criteria for this analysis, 17 studies evaluated pain as a primary or secondary outcome, and 15 studies evaluated pain, pillar tenderness, or incision tenderness at short-term follow-up. Most studies employed a VAS for assessment, and the majority reported superior short-term pain outcomes following ECTR at intervals ranging from one hour up to 12 weeks. Several additional studies reported equivalent pain outcomes at short-term follow-up as early as one week. No study reported inferior short-term pain outcomes following ECTR. CONCLUSIONS: ECTR and OCTR produce satisfactory results in pain relief, symptom resolution, patient satisfaction, time to return to work, and adverse events. There is a growing body of evidence favoring the endoscopic technique for pain relief, functional outcomes, and satisfaction, at least in the early post-operative period, even if this difference disappears over time. Several studies have demonstrated a quicker return to work and activities of daily living with the endoscopic technique.

Spinal Cord Stimulation vs Conventional Therapies for the Treatment of Chronic Low Back and Leg Pain: A Systematic Review of Health Care Resource Utilization and Outcomes in the Last Decade.

OBJECTIVE: The purpose of this review is to critically appraise the literature for evidence supporting the health care resource utilization and cost-effectiveness of spinal cord stimulation (SCS) compared with conventional therapies (CTs) for chronic low back and leg pain. METHODS: The PubMed, MEDLINE, Embase, CINAHL, and Rehabilitation & Sports Medicine databases were searched for studies published from January 2008 through October 2018, using the following MeSH terms: "spinal cord stimulation," "chronic pain," "back pain," "patient readmission," "economics," and "costs and cost analysis." Additional sources were added based on bibliographies and consultation with experts. The following data were extracted and analyzed: demographic information, study design, objectives, sample sizes, outcome measures, SCS indications, complications, costs, readmissions, and resource utilization data. RESULTS: Of 204 studies screened, 11 studies met inclusion criteria, representing 31,439 SCS patients and 299,182 CT patients. The mean age was 53.5 years for SCS and 55.6 years for CT. In eight of 11 studies, SCS was associated with favorable outcomes and found to be more cost-effective than CT for chronic low back pain. Compared with CT, SCS resulted in shorter hospital stays and lower complication rates and health care costs at 90 days. SCS was associated with significant improvement in health-related quality of life, health status, and quality-adjusted life-years. CONCLUSIONS: For the treatment of chronic low back and leg pain, the majority of studies are of fair quality, with level 3 or 4 evidence in support of SCS as potentially more cost-effective than CT, with less resource expenditure but higher complication rates. SCS therapy may yet play a role in mitigating the financial burden associated with chronic low back and leg pain.

A Systematic Review of Radiofrequency Treatment of the Ankle for the Management of Chronic Foot and Ankle Pain.

BACKGROUND: Chronic pain of the lower extremity remains challenging to manage. Radiofrequency treatment applies heat to nerve fibers with the goal of mitigating chronic pain conditions. The clinical efficacy has not yet been adequately established for pathologies of the ankle and foot. In this review paper, we report the use and efficacy of radiofrequency treatment applied to foot and ankle pain. RECENT FINDINGS: PubMed and the Cochrane Controlled Trials Register were searched (final search 30 March 2018) using the MeSH terms "radiofrequency ablation," "neurolysis," "radiofrequency therapy," "pain syndrome," "analgesia," "plantar heel pain," "plantar fascitis," and "chronic pain" in the English literature. Of the 23 papers screened, 18 were further investigated for relevance. Our final search methodology yielded 15 studies that investigated the use of radiofrequency treatment at the ankle. Of these 15 studies, there were three randomized control trials, four prospective studies, three retrospective studies, and five case reports. The quality of selected publications was assessed using the Cochrane risk of bias instrument. The evidence from our studies suggests that radiofrequency treatment can be used safely for the management foot and ankle pain. The technique (continuous vs pulsatile), temperature, location of treatment, and duration of administration need more thorough evaluation. Randomized control trials are needed to establish the efficacy and safety profile of radiofrequency ablation and its long-term benefits in patients with chronic pain of the foot and ankle. CONCLUSION: The evidence from our studies suggests that radiofrequency treatment can be used safely for the management foot and ankle pain. The technique (continuous vs pulsatile), temperature, location of treatment, and duration of administration need more thorough evaluation. Randomized control trials are needed to establish the efficacy and safety profile of radiofrequency ablation and its long-term benefits in patients with chronic pain of the foot and ankle.

Comparison of adverse events and postoperative mobilization following knee extensor mechanism rupture repair: A systematic review and network meta-analysis.

BACKGROUND: Extensor mechanism rupture (EMR) of the knee is a rare but potentially debilitating injury that often occurs due to trauma. While a wide variety of surgical treatments have been reported, there is currently no consensus on the most successful treatment method. The timing of post-operative joint mobilization is also critical for successful recovery after EMR repair. Despite the traditional method of complete immobilization for 6 weeks, there is an increasing trend towards early post-operative knee mobilization. The purpose of this network meta-analysis was to compare adverse event rates and function outcomes between repair methods and between post-operative mobilization protocols. METHODS: MEDLINE, EMBASE, Web of Science, and Cochrane Central electronic databases were searched in August 2016 for observational studies involving repair of acute, traumatic EMRs. Data extraction included functional outcomes, adverse events, and additional surgeries. Cohort studies that were used in functional outcome analysis were assessed for risk of bias by the Newcastle-Ottawa Quality Assessment Scale (NOS). RESULTS: Twenty-three studies (709 patients) were included for adverse event analysis. There were no significant differences in adverse event or additional surgery rates between EMR repair methods However, early mobilization produced significantly higher adverse event rates (p=0.02) and total event rates (p<0.001) than late mobilization, but the difference in additional surgery rates was not significant (p=0.06). Six studies (85 patients) were included for functional outcome analysis. There were no significant differences in thigh girth atrophy or muscle strength compared to the contralateral leg between patients treated with transosseous drill holes and simple end-to-end sutures. CONCLUSIONS: We performed the first network meta-analysis to date comparing treatment of EMRs. Our results support the current body of knowledge that there is no single superior repair method. Although there is an increasing trend towards early or immediate post-operative knee mobilization, we found that early mobilization is associated with significantly higher adverse event and total event rates compared to fixed immobilization for a minimum of 6 weeks, implicating an increased financial burden and decreased quality of life associated with early post-operative mobilization.
