    Abstract Meta-analyses represent the best available medical evidence. Although a powerful tool, they are not without criticisms since any bias in the original studies are then compounded when they are pooled together for the meta-analysis. Funnel plots provide a useful graphical representation of the presence of bias, and forest plots represent the heterogeneity of findings within studies included in a meta-analysis. The purpose of this review is to help readers interpret these statistical tools to better understand the findings of a meta-analysis.

    Abstract Hypothesis: This study aimed to explore the prognostic value of electrodiagnostic studies (EDS) to clarify their utility in clinical practice prior to cubital tunnel release surgery as well as identify patient factors associated with patient-reported functional improvement after surgery. Our hypothesis is that patients with severe preoperative findings on EDS will tend to experience less functional improvement after surgery given the extent of ulnar nerve compressive injury.
    Methods: Patients with cubital tunnel syndrome and preoperative electrodiagnostic data treated from 2012-2022 with cubital tunnel release were assessed regarding demographic information, preoperative physical exam findings, EDS findings, postoperative complications, and patient-reported outcomes. Short to mid-term qDASH scores were collected for all patients for further evaluation of preoperative EDS data. Patients were grouped into those who had met the MCID in delta qDASH at short to mid-term follow-up and those that did not. EDS data included sensory nerve onset latency, peak latency, amplitude, conduction velocity as well as motor nerve latency, velocity, and amplitude. Electromyogram (EMG) studies were also reviewed which included data pertaining to fibrillations, presence of abnormal fasciculation, positive sharp waves, variation in insertional activity, motor unit activity, duration of activity, and presence of increasing polymorphisms.
    Results: Of the 257 patients included, 160 (62.0%) were found to meet the MCID for short to mid-term qDASH scores. There were no significant differences between patients who did or did not meet the MCID regarding baseline demographics, comorbidities, preoperative exam findings, and operative technique. Patients who met MCID tended to have lower complication (3.80% vs 7.20%; p=0.248) and revision (0.60% vs 4.10%; p=0.069) rates but these findings were not statistically significant. The cubital tunnel severity as determined by the EDS was similar between cohorts (14.1% vs. 14.3%, p=0.498). Analysis of EMG testing showed there were no significant differences in preoperative, short to mid-term qDASH, or delta short to mid-term qDASH scores for patients with or without abnormal EMG findings. Multivariate regression suggested that only age (p=0.003) was associated with larger delta qDASH scores (Table 7).
    Conclusion: Patient-reported preoperative disease severity may predict the expected postoperative change in ulnar nerve functional improvement and EDS may not have prognostic value for patients undergoing cubital tunnel decompression. Therefore, physicians may suggest surgical treatment without positive EDS findings and still expect postoperative improvement in functional outcomes.

    Abstract Hypothesis: The purpose of this study was to compare inter-and intraobserver agreement of a novel intraoperative subluxation classification for patients undergoing ulnar nerve surgery at the elbow. We hypothesize there will be strong inter- and intraobserver agreement of the four-category classification system and reviewers will have substantial confidence while reviewing the classification system.
    Methods: Four blinded fellowship-trained orthopedic hand surgeons reviewed 25 videos in total on two separate viewings, 21 days apart. Variables collected were ulnar subluxation classification (A, B, C or D) and a confidence metric. Subsequent to primary data collection, classification grading was stratified into A/B or C/D subgroups for further analysis. Cohen's kappa scores were used to evaluate all variables collected in this study. The interpretation of kappa scores included ≤0.0 as no agreement, 0.01-0.20 as none to slight, 0.21-0.40 as fair, 0.41-0.60 as moderate, 0.61-0.80 as substantial, and 0.81-1.0 as almost perfect agreement.
    Results: Interobserver agreement of subluxation classification as a four-category scale demonstrated a moderate agreement on first viewing, second viewing, and when both viewings were combined (kappa=0.51, 0.51, and 0.51 respectively). Seventy-five percent (3 out of 4) of reviewers had moderate intraobserver agreement for ulnar nerve subluxation classification while one reviewer had substantial intraobserver classification (kappa= 0.72). Overall, there was high confidence in 65% of classification scores in the second round of viewing, which improved from 58% in the first viewing round. When ulnar subluxation classification selections were regrouped into classes A/B or C/D, 100% of reviewers had substantial interobserver (kappa=0.74 - 0.75) and substantial to almost perfect intraobserver (kappa=0.71 to 0.91) agreement.
    Conclusions: The four-category classification was reproducible within and between reviewers. Agreement appeared to increase when simplifying the classification to two categories, which may provide guidance to surgical decision making. The validation of a reproducible classification scheme for intraoperative ulnar subluxation may aid with decision making and further postoperative outcomes research.

    Abstract Background and purpose: Over 90% of patients undergoing cranial vault remodeling for craniosynostosis receive blood transfusions to compensate for intraoperative blood loss. However, transfusions are not without risk and can lead to allergic and immune transfusion reactions as well as rare cases of infectious transmissions. Preoperative use of erythropoietin in cranial vault remodeling has been demonstrated to be safe and to reduce transfusion requirements in prior studies. This study's purpose is to add to the body of data supporting the safe use of a protocolized erythropoietin alfa regimen before cranial vault remodeling and strip craniectomy procedures with decreased blood transfusion requirements and other favorable outcomes.
    Methods: A retrospective chart review was performed on patients who underwent cranial vault remodeling between 2006 and 2021 at our tertiary care center. Two groups were identified: in the first, preoperative erythropoietin was administered under protocol; and in the second, preoperative erythropoietin was not administered. The groups were compared with respect to age, perioperative hemoglobin levels, estimated blood loss during surgery, packed red blood cell transfusion volume, length of hospital stay, and length of surgery.
    Results: Demographics were not significantly different in terms of age, weight, diagnosis, gender, and type of procedure. Patients who were administered preoperative erythropoietin were found to have significantly increased preoperative hemoglobin levels (13.6 versus 12.3 g/dL), as well as decreased estimated intraoperative blood loss (376 versus 1099 mL), the volume of packed red blood cells transfused (316 versus 897 mL), length of hospital stay, and length of surgery. Postoperative hemoglobin levels were not found to be significantly different.
    Conclusions: In this study, preoperative administration of erythropoietin with elemental iron was beneficial for patients undergoing cranial vault remodeling for craniosynostosis. Specifically, it decreased the need for red blood cell transfusion, intraoperative blood loss, and length of hospital stay. No adverse events were recorded in the treatment arm. Further studies may include a separate group administered iron alone.

    Abstract This is a case report of an 85-year-old woman with osteopenia who underwent olecranon avulsion fracture repair with supplemental triceps tendon repair following a fall on an outstretched arm. The initial procedure failed due to osteoporotic bone quality and an atraumatic disruption of the olecranon fracture fixation. The patient subsequently underwent further surgical intervention with an olecranon avulsion fracture excision and a novel triceps tendon repair technique using plate augmentation and fiber tape. Surgeons may consider this novel approach as an initial treatment for elderly patients with osteopenia or osteoporosis undergoing olecranon avulsion fracture fixation, to prevent the failure and consequent revision surgery.

    Abstract 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.

    Abstract Introduction With the rising number of arthroscopic partial meniscectomy and meniscus repair procedures performed in outpatient surgical centers, there has been significant interest in limiting postoperative pain and optimizing recovery. Postoperative pain is a common reason for admission at these surgical centers, and opioid-related mortality is becoming an increasing concern. A surgeon-performed saphenous nerve block (SNB) represents a promising adjunct treatment option for pain control. The purpose of this randomized controlled trial was to determine if an SNB would result in decreased postoperative pain and opioid usage compared to control following arthroscopic meniscus repair or partial meniscectomy. Methods We randomized patients between two groups: one receiving an SNB and the other without an SNB. The operating surgeon performed the SNB using a landmark-based approach at the medial femoral epicondyle/adductor hiatus with 5 mL of 1% lidocaine preoperatively and 5 mL of 0.5% ropivacaine postoperatively. Neither ultrasound nor nerve stimulator was utilized to confirm the success of the block. The visual analog scale was utilized to record pain preoperatively and in the immediate postoperative period, one day, and seven to 10 days postoperatively. The nursing staff in the post-anesthesia care unit monitored patient pain levels and provided pain medication accordingly. Results We enrolled 80 patients, with 40 patients in each group. There was no difference in age, sex, body mass index, or laterality between study groups. Overall, there were no differences between groups in preoperative or postoperative pain at any time. The average pain scores preoperatively were 2.78 in the experimental group and 3.05 in the control group (p=0.502). In the immediate postoperative period, pain scores were 1.57 for the experimental group and 2.66 for the control group (p=0.090). No statistically significant difference was detected in the number of patients requiring opioids postoperatively or in the morphine milligram equivalents (MME) provided to patients receiving opioids. Twelve patients in the experimental group received opioids in the immediate postoperative period while 18 patients in the control group received opioids (p=0.248). We observed no adverse events in patients from either group. Conclusion As a pure sensory nerve, the saphenous nerve is an excellent target for pain control without associated leg weakness. We utilized a low-resource SNB in knee arthroscopy for partial meniscectomy and meniscus repair as an adjunct therapy for postoperative pain control. This randomized controlled trial suggests that surgeon-performed blocks via a landmark-based approach are not effective in controlling pain or limiting opioid use in the immediate postoperative period. However, given our lack of confirmatory testing via ultrasound or nerve stimulation, a true nerve block may not have been achieved in all patients. We believe this adds to the external validity of this study, as these tools may not be readily available in all settings.

    Abstract Use of the Masquelet technique in the hand is uncommon, particularly for cases complicated by osteomyelitis. This case report describes a patient who was advised to proceed with digital amputation following the traumatic segmental bone loss with a non-salvageable distal interphalangeal joint surface complicated by osteomyelitis but refused amputation and requested alternative treatment. We suggested and performed the Masquelet procedure and arthrodesis to salvage the digit. The first stage consisted of surgical debridement and placement of an antibiotic cement spacer, and the second stage included the replacement of the antibiotic cement spacer with an iliac crest autograft and arthrodesis eight weeks after the primary procedure. The Masquelet technique led to the resolution of osteomyelitis, successful osseous union, finger ray salvage, and distal interphalangeal joint arthrodesis.

    Abstract Background: Accurate acetabular cup orientation is associated with decreased revision rates and improved outcomes of primary total hip arthroplasty. This study assesses surgeon's ability to estimate both the acetabular component inclination and anteversion angles via intraoperative fluoroscopy (IF) images.
    Methods: We surveyed orthopedic surgeons to estimate acetabular component inclination and anteversion based on 20 IF images of total hip arthroplasty through a direct anterior approach. Postoperative computed-tomography scans were used to calculate the true inclination and anteversion component angles. The absolute difference between the true and estimated values was calculated to determine the mean and standard deviation of the survey results. Interrater reliability was determined through interclass correlation coefficients.
    Results: A majority of surgeons preferred the direct anterior approach (83.3%) and utilized IF during surgery (70%). Surgeons surveyed were on average 5.9° away from the true value of inclination (standard deviation = 4.7) and 8.8° away from the true value of anteversion (standard deviation = 6.0). Respondents were within 5° of both inclination and anteversion in 19.7% of cases, and within 10° in 57.3% of cases. All surgeons were determined to have poor reliability in estimating anteversion (interclass correlation coefficient < 0.5). Only 2 surgeons were determined to have moderate reliability when estimating inclination.
    Conclusions: Surgeons, when solely relying on IF for the estimation of anteversion and inclination, are unreliable. Utilization of other techniques in conjunction with IF would improve observer reliability.
