RESUMEN
Introduction: The role of elective rotations in the orthopaedic residency selection process varies between programs. Our study aims to identify factors associated with residency programs that interview and match a greater proportion of applicants who have completed an elective rotation with their program. Methods: Data were collected through the American Orthopaedic Association's Orthopaedic Residency Information Network database. Bivariate correlations and multivariate regression models were used to identify independent predictors of programs with a greater proportion of interviewees or residents who completed an elective rotation at the respective program. Results: One hundred seventy-eight of the 218 existing residency programs were included in this study. Programs that offered fewer interviews and more away rotation positions per year were associated with a greater odds of its interviewees (OR = 0.36, p = 0.01; OR = 4.55, p < 0.001, respectively) and residents (OR = 0.44, p = 0.04; OR = 4.23, p < 0.001, respectively) having completed an elective rotation with the program. In addition, programs with fewer attendings (OR = 0.39, p = 0.03) and in-person interviews (OR = 3.04, p = 0.04) matched a greater proportion of their rotators. However, programs that interviewed applicants during the elective rotation were less likely to match their rotators (OR = 0.35, p = 0.04). Conclusion: Certain program characteristics independently predict the likelihood of a program interviewing and matching their rotators. These findings may provide information for applicants and programs regarding the rotation process. Level of Evidence: III.
RESUMEN
BACKGROUND: Readmission rate after surgery is an important outcome measure in revealing disparities. This study aimed to examine how 30-day readmission rates and causes of readmission differ by race and specific injury areas within orthopaedic surgery. METHODS: The American College of Surgeon-National Surgical Quality Improvement Program database was queried for orthopaedic procedures from 2015 to 2019. Patients were stratified by self-reported race. Procedures were stratified using current procedural terminology codes corresponding to given injury areas. Multiple logistic regression was done to evaluate associations between race and all-cause readmission risk, and risk of readmission due to specific causes. RESULTS: Of 780,043 orthopaedic patients, the overall 30-day readmission rate was 4.18%. Black and Asian patients were at greater (OR = 1.18, P < 0.01) and lesser (OR = 0.76, P < 0.01) risk for readmission than White patients, respectively. Black patients were more likely to be readmitted for deep surgical site infection (OR = 1.25, P = 0.03), PE (OR = 1.64, P < 0.01), or wound disruption (OR = 1.45, P < 0.01). For all races, all-cause readmission was highest after spine procedures and lowest after hand/wrist procedures. CONCLUSIONS: Black patients were at greater risk for overall, spine, shoulder/elbow, hand/wrist, and hip/knee all-cause readmission. Asian patients were at lower risk for overall, spine, hand/wrist, and hip/knee surgery all-cause readmission. Our findings can identify complications that should be more carefully monitored in certain patient populations.

BACKGROUND: Although cementation of humeral stems has long been considered the gold standard for anatomic shoulder arthroplasty (aTSA), cementless, or press-fit, fixation offers a relatively cheaper and less demanding alternative, particularly in the setting of a revision procedure. However, this approach has been accompanied by concerns of implant loosening and high rates of radiolucency. In the present study, we performed a propensity-matched comparison of clinical and patient-reported outcomes between cemented and cementless fixation techniques for aTSA. We hypothesized that cemented fixation of the humeral component would have significantly better implant survival while providing comparable functional outcomes at final follow-up. METHODS: This study was a retrospective comparison of 50 shoulders undergoing aTSA: 25 using cemented humeral fixation vs. 25 using press-fit humeral fixation. Patients in the 2 groups were propensity matched according to age, sex, and preoperative American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score. Primary outcome measures included range of motion (ROM) (forward elevation, external rotation, internal rotation), patient-reported outcomes (ASES, Simple Shoulder Test [SST], visual analog scale [VAS]), and implant survival. RESULTS: At baseline, the 2 fixation groups were similar in regard to age, sex, body mass index, preoperative ASES score, and surgical indication. Mean follow-up was 11.7 ± 4.95 years in the cemented cohort and 9.13 ± 3.77 years in the press-fit cohort (P = .045). Both groups demonstrated significant improvements postoperatively in all included ROM and patient-reported outcomes. However, press-fit patients reported significantly better VAS, ASES, and SST scores. Mean VAS pain score was 1.1 ± 1.8 in press-fit patients and 3.2 ± 3.0 in cemented patients (P = .005). The mean ASES score was 87.7 ± 12.4 in press-fit patients and 69.5 ± 22.7 in cemented patients (P = .002). Lastly, the mean SST score was 9.8 ± 3.1 in press-fit patients and 7.7 ± 3.7 in cemented patients (P = .040). Both fixation techniques provided lasting implant survivorship with only a single revision operation in each of the cohorts. CONCLUSION: Herein, we provide a propensity-matched, long-term comparison of patients receiving anatomic shoulder arthroplasty stratified according to humeral stem fixation technique. The results of this analysis illustrate that both types of humeral fixation techniques yield durable and significant improvements in shoulder function with similar rates of survival at 10 years of follow-up.

PURPOSE: To provide an overview of the existing literature on subacromial balloon spacers for the treatment of massive irreparable rotator cuff tears, in an effort to inform surgeons of the procedure's clinical effectiveness. METHODS: The PubMed, Scopus, and Ovid EMBASE databases were queried to identify studies evaluating the clinical, radiographic, and patient-reported outcomes of patients indicated for subacromial balloon spacer implantation. The following datapoints were extracted: study demographics, patient baseline characteristics, and postoperative outcomes of interest. Outcomes were evaluated at baseline and at the longest available follow-up period. RESULTS: A total 766 patients were included among 22 included studies, with an average follow-up of 27.54 months. Improvements were seen for all clinical and patient-reported outcomes: forward elevation (ranging from 9.20 to 90.00° improvement), external rotation (ranging from 2.00 to 22.00°), abduction (ranging from 14.00 to 95.00°), Total Constant Score (ranging from 7.70 to 50.00), American Shoulder and Elbow Surgeons score (ranging from 24.60 to 59.84), Oxford Shoulder Score (ranging from 7.20 to 22.20), and pain score (ranging from 3.57 to 6.50). Minimal differences were seen in acromiohumeral interval (ranging from -2.00 to 1.27). Reoperation and complication rates ranged from 0% to 33% and 0% to 19.64%, respectively. CONCLUSIONS: The short-term results of subacromial balloon spacers for management of massive rotator cuff tears demonstrate clinically relevant improvements in shoulder range of motion and substantial improvements in patient-reported outcome measures. Of note, minimal change in acromiohumeral interval was seen on postoperative radiography, and wide variations in complication and reoperation rates were reported across studies. LEVEL OF EVIDENCE: Level IV, systematic review of Level I-IV studies.

PURPOSE: To assess the complication risks associated with intrathecal baclofen (ITB) pumps in cerebral palsy (CP) patients undergoing posterior spinal fusion (PSF) and to determine if timing of pump implantation before or during PSF impacts the risk of complications. METHODS: A prospectively collected multicenter database was retrospectively reviewed to identify CP patients undergoing PSF from 2008 to 2023. Patients were divided into 2 cohorts: those with an ITB pump (ITB cohort) and those without (non-ITB cohort). The ITB cohort was further categorized by placement of the pump prior to or during PSF. Cohorts were then compared in terms of postoperative complications, perioperative complications, and need for revision surgery. RESULTS: Four hundred six patients (ITB n = 79 [53 prior to, 26 during PSF], non-ITB n = 326) were included in this analysis. At an average follow-up of 4.0 years (range 2-10 years), there were no significant differences between the ITB and non-ITB cohorts in the rate of perioperative complications (5.0% vs 6.5%, p = 0.80), revision surgeries (2.5% vs 4.6%, p = 0.54), or any complication type, regardless of whether pumps were placed prior to or during PSF, aside from longer surgical times in the latter group. CONCLUSION: Complication rates are similar for ITBs placed prior to and during PSF. Patients with spastic CP may safely be treated with ITB pumps without increased risks of complication or further reoperation/revision following PSF. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Unicompartmental knee arthroplasty (UKA) offers a less invasive alternative to total knee arthroplasty (TKA), but is accompanied by a high revision risk. The aim of our study was to perform a meta-analysis comparing outcomes of UKA revised to TKA versus primary TKA, to assess if UKA is an effective treatment option, despite its potential need for revision. METHODS: Studies comparing matched cohorts of patients with UKA revised to TKA versus primary TKA were identified via the PubMed, Ovid EMBASE, and Scopus databases. The following outcome measures were compared between treatment modalities: postoperative reoperation or revision, total complications, range of motion, patient-reported outcome measures, and length of stay. RESULTS: Ten studies were included with 1,070 patients: 410 UKA to TKA and 660 primary TKA. At an average follow-up of 5.6 years in the UKA to TKA cohort and 5.7 years in the primary TKA cohort, there were no significant difference in risk of revision (p = 0.81), total complications (p = 0.54), range of motion (p = 0.09), or length of stay (p = 0.31). Both objective and functional Knee Society Score were significantly higher in patients with primary TKA (p < 0.01). However, there was no difference in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) or pain scores (p = 0.13 and p = 0.21, respectively). CONCLUSION: UKA revised to TKA produced comparable clinical and patient-reported outcomes to a primary TKA. UKA may be an effective treatment option in unicompartmental arthritis that would allow for improved functionality and satisfaction without the concern of outcomes deteriorating in patients where a revision becomes necessary.

BACKGROUND: For anatomic total arthroscopic repair, cementless humeral fixation has recently gained popularity. However, few studies have compared clinical, radiographic, and patient-reported outcomes between cemented and press-fit humeral fixation, and none have performed follow-up for longer than 5 years. In this study, we compared long-term postoperative outcomes in patients receiving a cemented versus press-fit humeral stem anatomic arthroscopic repair. METHODS: This study retrospectively analyzed 169 shoulders that required primary anatomic total shoulder arthroplasty (aTSA). Shoulders were stratified by humeral stem fixation technique: cementation or press-fit. Data were collected pre- and postoperatively. Primary outcome measures included range of motion, patient reported outcomes, and radiographic measures. RESULTS: One hundred thirty-eight cemented humeral stems and 31 press-fit stems were included. Significant improvements in range of motion were seen in all aTSA patients with no significant differences between final cemented and press-fit stems (forward elevation: P=0.12, external rotation: P=0.60, and internal rotation: P=0.77). Patient reported outcome metrics also exhibited sustained improvement through final follow-up. However, at final follow-up, the press-fit stem cohort had significantly better overall scores when compared to the cemented cohort (visual analog score: P=0.04, American Shoulder and Elbow Surgeon Score: P<0.01, Simple Shoulder Test score: P=0.03). Humeral radiolucency was noted in two cemented implants and one press-fit implant. No significant differences in implant survival were observed between the two cohorts (P=0.75). CONCLUSIONS: In this series, we found that irrespective of humeral fixation technique, aTSA significantly improves shoulder function. However, within this cohort, press-fit stems provided significantly better outcomes than cemented stems in terms of patient reported outcome scores. Level of evidence: III.
RESUMEN
Background: The recent increasing popularity of shoulder arthroplasty has been paralleled by a rise in prevalence of diabetes in the United States. We aimed to evaluate the impact of diabetes status on readmission and short-term complications among patients undergoing shoulder arthroplasty. Methods: We analyzed the Healthcare Cost and Utilization Project National Readmissions Database (NRD) between the years 2016-2018. Patients were included in the study if they underwent anatomic total shoulder arthroplasty (aTSA) or reverse total shoulder arthroplasty (rTSA) according to ICD-10 procedure codes. Postoperative complications including surgical site/joint infection, dislocation, prosthetic complications, hardware-related complications, non-infectious wound complications, 30-day, and 90-day readmission were collected. Results: A total of 113,713 shoulder arthroplasty patients were included. 23,749 (20.9%) had a diagnosis of diabetes and 89,964 (79.1%) did not. On multivariate analysis, a diagnosis of diabetes led to an increased risk of 30-day (OR: 1.24; 95% CI: [1.14, 1.34]; p < 0.001) and 90-day (OR: 1.18; 95% CI: [1.12, 1.25]; p < 0.001) readmission, surgical site/joint infection (OR: 1.21; 95% CI: [1.06, 1.38]; p = 0.005), respiratory complication (OR: 1.34; 95% CI: [1.09, 1.64]; p = 0.005), postoperative infection (OR: 1.22; 95% CI [1.07, 1.39]; p = 0.003), and deep vein thrombosis (OR: 1.38; 95% CI: [1.09, 1.74]; p = 0.007). Conclusions: Our findings suggest that patients with diabetes may be at an increased risk of readmission, infection, respiratory complication, and deep vein thrombosis following shoulder arthroplasty. Shoulder surgeons should consider these potential adverse events when planning postoperative care for patients with diabetes.
RESUMEN
OBJECTIVE: Patients with diabetes have poorer outcomes with coronary artery disease (CAD) and pose a unique clinical population for revascularization. We performed a pairwise meta-analysis of randomized trials (RCTs) and propensity-matched observational studies (PMS) to compare the clinical outcomes of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients with diabetes. METHODS: A comprehensive literature search was performed to identify RCT and PMS studies comparing CABG with PCI in patients with diabetes with concurrent CAD. Studies were pooled using the random-effects model to perform a pairwise meta-analysis. Primary outcomes included long-term all-cause mortality, cardiac mortality, myocardial infarction (MI), major adverse cardiac and cerebrovascular events (MACCE), and repeat revascularization. Meta-regression was used to explore the effects of baseline risk factors on primary outcomes with moderate to high heterogeneity. RESULTS: A total of 18 RCTs and 9 PMS with 28,846 patients were included. PCI was associated with increased long-term all-cause mortality (risk ratio [RR] = 1.34, P < 0.001), cardiac mortality (RR = 1.52, P < 0.001), MI (RR = 1.51, P = 0.009), MACCE (RR = 1.65, P < 0.001), and repeat revascularization (RR = 2.48, P < 0.001) compared with CABG. There was no difference in long-term stroke between the 2 groups (RR = 0.95, P = 0.82). At meta-regression, a greater proportion of female patients in studies was associated with a decreased protective benefit for CABG for long-term all-cause mortality but an increased protective benefit for long-term MI and repeat revascularization. CONCLUSIONS: Revascularization of patients with diabetes using CABG is associated with significantly reduced long-term mortality, MI, MACCE, and repeat revascularizations. Future studies exploring the influence of gender on revascularization outcomes are necessary to elucidate the ideal treatment modality in patients with diabetes.

Greater faculty diversity within orthopaedic residency programs has been associated with an increased application rate from students of similarly diverse demographic backgrounds. It is unknown whether these underrepresented student populations have an equitable likelihood of being highly ranked and matching at these programs. Thus, we sought to evaluate the relationship between faculty and resident diversity, with a specific focus on sex, racial/ethnic groups that are underrepresented in medicine (URiM), and international medical graduates (IMGs). Methods: The American Orthopaedic Association's Orthopaedic Residency Information Network database was used to collect demographic data on 172 US residency programs. Linear regression analyses were performed to determine the relationship between the proportion of female or URiM attendings at a program and the proportion of female, URiM, or IMG residents or top-ranked applicants (≥25 rank). URiM was defined as "racial and ethnic populations that are underrepresented in the medical profession relative to their numbers in the general population." Results: A mean of 13.55% of attendings were female and 14.14% were URiM. A larger fraction of female attendings was a positive predictor of female residents (p < 0.001). Similarly, a larger percentage of URiM attendings was a positive predictor of URiM residents (p < 0.001), as well as of URiM (p < 0.001) and IMG (p < 0.01) students being ranked highly. There was no significant association between URiM attendings and female residents/overall top-ranked applicants, or vice versa. Conclusions: Residency programs with more female attendings were more likely to match female residents, and programs with more URiM attendings were more likely to highly rank URiM and IMG applicants as well as match URiM residents. Our findings indicate that orthopaedic surgery residencies may be more likely to rank and match female or URiM students at similar proportions to that of their faculty. This may reflect minority students preferentially applying to programs with more diverse faculty because they feel a better sense of fit and are likely to benefit from a stronger support system. Level of Evidence: III.
RESUMEN
BACKGROUND: Surgical approaches to the proximal interphalangeal (PIP) joint often require disruption of soft tissue stabilizers. Additionally, PIP joint injuries frequently result in soft tissue disruption. This study evaluates the necessity of repairing soft tissue stabilizers by assessing their role in maintaining native joint congruity. METHODS: Eight specimens were used to evaluate congruity at 0° and 30° flexion when loaded with 2 N of valgus force. This was performed in the native joint and after sequential sectioning of the surrounding ligaments in order: volar plate (VP), radial collateral ligament (CL), and ulnar CL. The skin flap was sutured with the ligaments unrepaired and the load was reapplied. Radiographs were taken after each load and used to measure the joint line convergence angle (JLCA). RESULTS: Mean JLCA increased in both degrees of flexion after ligaments were sectioned but was only significantly different from the native joint after the VP was disrupted along with 1 CL. Joint congruity improved following repair of the skin flap in both degrees of flexion but was not significant. Joints were more congruent in 30° flexion for all subgroups, but none were significantly different compared to 0° flexion. CONCLUSIONS: Disruption of the VP is insufficient to significantly alter PIP joint congruity. While sectioning of both the VP and CLs resulted in a statistically significant change in joint congruity, mean JLCA demonstrated changes of minor clinical significance. The osseous anatomy of the phalanges imparts inherent stability that maintains a congruent joint despite loss of the soft tissue stabilizers.

PURPOSE: Differences in range of motion, pinch strength, biomechanical strength, or joint angulation have previously been investigated for various means of treatment of ulnar collateral ligament (UCL) tears. We sought to address a gap in the literature by comparing thumb metacarpophalangeal (MCP) joint angle measurements and biomechanical strength before complete, acute UCL tear and after repair with suture anchors (SA), suture tape (ST) anchor augmentation, or reconstruction with palmaris longus graft (PL). METHODS: Thumbs and, if present, the PL tendon were harvested from 15 fresh-frozen cadavers. Each thumb specimen was secured into a servohydraulic biomechanical testing frame to evaluate native radiographic MCP joint angles at 0° flexion when loaded with 0, 5, and 13 N of radial force. Subsequently, a single hand surgeon (S.M.K.) performed complete transection and UCL repair via 1 of 3 methods: SA (n = 5), ST (n = 5), or reconstruction with PL (n = 5). Following repair, MCP joint angles were radiographically evaluated. Specimens that did not fail during joint angle testing were transferred to a separate testing frame for load-to-failure testing. Angle measurements and mean load-to-failure were compared between the groups, and angulation was also compared with each group's native control. RESULTS: Both ST and SA groups demonstrated comparable stiffness to their native controls, whereas the PL group was significantly more lax. The ST repair was significantly stiffer than the other constructs. ST also required higher forces to reach failure compared to both SA and PL. No difference was found between SA and PL groups. CONCLUSIONS: Although both ST and SA constructs recapitulate native joint stiffness, repair with ST demonstrated the greatest biomechanical strength in stiffness and load-to-failure. CLINICAL RELEVANCE: For complete, acute tears of the thumb UCL, ST may be superior for maintaining MCP joint stability and strength over SA and PL.

Background: The recently validated Hand Questionnaire (HAND-Q) is a multifaceted patient-reported outcome measure (PROM) for hand/upper extremity (UE) pathology and treatment. Here, we conduct a pilot study utilising data collected as a participating site for the Phase II HAND-Q Pilot Multicenter International Validation Study. We hypothesised that self-reported hand functionality, symptom/disease severity, hand appearance, emotional dissatisfaction and treatment satisfaction would be worse in patients who perceived their disease severity to be more severe but would not differ between patients based on prior surgical history. Methods: Patients were prospectively enrolled for HAND-Q participation from September 2018 to August 2019. Patients were included in this analysis if they responded to the following scales of HAND-Q: Hand Functionality Satisfaction, Symptom Severity, Hand Appearance Satisfaction, Emotional Dissatisfaction and Treatment Satisfaction. Composite scores (CS) were created for each section. Surgical versus non-surgical CS and mild versus moderate/severe CS were compared with t-tests. Bi-variate comparisons of responses were performed between surgical and non-surgical groups, and between mild and moderate/severe groups. Results: HAND-Q individual question analysis revealed significant differences in functionality and symptom severity for patients with prior surgery (p < 0.047). CS analysis confirmed greater overall impairment in surgical patients, but no overall impact on symptom severity. Regarding disease severity HAND-Q individual question analysis, moderate/severe patients reported worse outcomes for specific aesthetic qualities and symptoms for almost all items (p < 0.05). CS analysis revealed significantly worse overall hand appearance satisfaction, hand functionality, emotional satisfaction and symptom severity for patients with moderate/severe hand conditions. Conclusions: HAND-Q revealed worsened outcomes for UE patients with self-reported moderate/severe conditions or previous surgical history. Understanding how previous surgery and disease severity may impact clinical outcomes is important for crafting appropriate treatment. Level of Evidence: Level II (Prognostic Study).

Using the hand questionnaire (HAND-Q) patient-reported outcome measure, the effects of upper extremity surgery on patients' perception of their sex life were explored. The hand is a uniquely sexual organ, and we hypothesized that self-reported measures of disease severity, quality of life, and emotional impact would correlate with sexual dissatisfaction among patients receiving treatment for hand/upper extremity conditions. Methods: Patients were prospectively enrolled for hand questionnaire participation. Patients with valid responses to the following questions were included: functionality, hand appearance satisfaction, symptom severity, emotional dissatisfaction, sexual dissatisfaction, and treatment satisfaction. Composite scores were created and scored. Sexual dissatisfaction composite scores were compared through Spearman correlation coefficient analysis to quality of life, emotional dissatisfaction, hand appearance, symptom severity, and hand functionality. Results: High levels of diminished quality of life correlated with sexual dissatisfaction (rs = 0.748, P < 0.001). Increased emotional dissatisfaction correlated with sexual dissatisfaction (rs = 0.827, P < 0.001). Increased satisfaction with hand appearance negatively correlated with sexual dissatisfaction (rs = -0.648, P = 0.001). Increased levels of dissatisfaction with hand functionality correlated with sexual dissatisfaction (rs = 0.526, P = 0.005). Conclusions: The correlation between sex life and quality of life may allow surgeons to improve patient satisfaction when treating hand/upper extremity issues. The relationship between sex life and emotional dissatisfaction emphasizes the impact that sexual dissatisfaction has on patients' lives. Evaluating the relationship between hand appearance and sexual dissatisfaction may indicate that patient self-perception of hand attractiveness plays a role in sex life.
RESUMEN
BACKGROUND: Previous studies have suggested that proximal row carpectomy (PRC) results in increased contact pressures and decreased contact areas in the radiocarpal joint. Such experiments, however, used older technologies that may be associated with considerable measurement errors. The purpose of this study was to determine whether there was a significant difference in contact pressure and contact area before and after PRC using Tekscan, a newer pressure sensing technology. METHODS: Ten nonpaired cadaveric specimens were dissected proximal to the carpal row and potted. An ultra-thin Tekscan sensor was secured in the lunate fossa of the radius. The wrists were loaded with 200 N of force for 60 seconds to simulate clenched-fist grip; contact pressure and area was assessed before and after PRC. RESULTS: Performing a PRC did not significantly increase mean contact pressure at the lunate fossa compared to the native state (mean increase of 17.4 ± 43.2 N/cm2, P = .184). Similarly, the PRC did not significantly alter peak contact pressures at the lunate fossa (intact: 617.2 ± 233.46 N/cm2, median = 637.5 N/cm2; PRC: 707.8 ± 156.6 N/cm2, median = 728.5 N/cm2; P = .169). In addition, the PRC (0.46 ± 0.15 cm2, median = 0.48 cm2) and intact states (0.49 ± 0.25 cm2, median = 0.44 cm2) demonstrated similar contact areas (P = .681). CONCLUSIONS: In contrast to prior studies that demonstrated significant increases in contact pressure and decreases in contact area after PRC, our findings propose that performing a PRC does not significantly alter the contact pressures or area of the lunate fossa of the radiocarpal joint.
RESUMEN
Background The scapholunate interosseous ligament (SLIL) couples the scaphoid and lunate, preventing motion and instability. Prior studies suggest that damage to the SLIL may significantly alter contact pressures of the radiocarpal joint. Questions/Purposes The purpose of this study was to investigate the contact pressure and contact area in the scaphoid and lunate fossae of the radius prior to and after sectioning the SLIL. Methods Ten cadaveric forearms were dissected distal to 1-cm proximal to the radiocarpal joint and a Tekscan sensor was placed in the radiocarpal joint. The potted specimen was mounted and an axial load of 200 N was applied over 60 seconds. Results Sectioning of the SLIL did neither significantly alter mean contact pressure at the lunate fossa ( p = 0.842) nor scaphoid fossa ( p = 0.760). Peak pressures were similar between both states at the lunate and scaphoid fossae ( p = 0.301-0.959). Contact areas were similar at the lunate fossa ( p = 0.508) but trended toward an increase in the SLIL sectioned state in the scaphoid fossa ( p = 0.055). No significant differences in the distribution of contact pressure ( p = 0.799), peak pressure ( p = 0.445), and contact area ( p = 0.203) between the scaphoid and lunate fossae after sectioning were observed. Conclusion Complete sectioning of the SLIL in isolation may not be sufficient to alter the contact pressures of the wrist. Clinical Relevance Injury to the secondary stabilizers of the SL joint, in addition to complete sectioning of the SLIL, may be needed to induce altered biomechanics and ultimately degenerative changes of the radiocarpal joint.
RESUMEN
Background: The use of minor field sterility in hand/upper extremity cases has been shown to improve workflow efficiency while maintaining patient safety. As this finding has been limited to specific procedures, we investigated the safety of performing a wide array of hand/upper extremity procedures outside the main operating room using minimal field sterility with Wide-Awake Local Anaesthesia No Tourniquet (WALANT) anaesthesia by evaluating superficial and deep infection rates across a diverse series of cases. Methods: This study was a case series conducted between October 2017 and June 2020. Of all, 217 patients underwent hand/upper extremity procedures performed in a minor procedure room via WALANT technique with field sterility. Primary outcome measures include superficial and deep surgical site infections within 14 days post-surgery. Results: Of all, 217 patients were included in this study; 265 consecutive hand/upper extremity operations were performed by a single surgeon, with notable case diversity. The majority of patients (n = 215, 99.1%) did not report or present with signs of infection before or after their operation. We report 0% 14-day and 0.37% 30-day surgical site infection rates for such hand/upper extremity procedures performed in a minor procedure room with field sterility. Conclusion: Hand/upper extremity procedures performed via WALANT technique with field sterility in a minor procedure room are associated with low surgical site infection rates. These rates are comparable to surgical site infection rates for similar surgeries performed in main operating rooms with standard sterilization procedures. Thus, the implementation of this technique may allow for improved workflow efficiency and reduced waste, all while maintaining patient safety.
Historique: Il est démontré que le recours à un champ stérile mineur dans les interventions de la main et des extrémités supérieures améliore le déroulement du travail tout en maintenant la sécurité du patient. Comme cette observation se limite à des interventions particulières, les chercheurs ont examiné la sécurité d'un large éventail d'interventions de la main et des extrémités supérieures au moyen de la technique d'anesthésie de WALANT (acronyme anglais d'anesthésie locale en plein éveil sans tourniquet) hors de la salle d'opération principale. Pour ce faire, ils ont évalué le taux d'infections superficielles et profondes dans une série de cas variés. Méthodologie: La présente série de cas a été réalisée entre octobre 2017 et juin 2020. Au total, 217 patients ont subi une intervention mineure de la main ou des extrémités supérieures exécutée dans une salle d'intervention mineure sur champ stérile au moyen de la technique d'anesthésie de WALANT. Les mesures de résultat primaire incluaient des infections superficielles et profondes au foyer chirurgical dans les 14 jours suivant l'intervention. Résultats: Au total, 217 patients ont participé à l'étude. Un seul chirurgien a effectué 265 opérations consécutives de la main ou des extrémités supérieures, d'une diversité remarquable. La majorité des patients (n = 215, 99,1 %) n'ont pas déclaré ni présenté de signes d'infection avant ou après leur opération. Les chercheurs ont déclaré un taux d'infection de 0 % au foyer chirurgical au bout de 14 jours et de 0,37 % au bout de 30 jours pour les interventions de la main et des extrémités exécutées sur champ stérile dans une salle d'intervention mineure. Conclusion: Les interventions de la main et des extrémités supérieures exécutées sur champ stérile par la technique d'anesthésie de WALANT dans une salle d'intervention mineure sont liées à un faible taux d'infection au foyer chirurgical. Ces taux sont comparables à ceux des infections au foyer chirurgical lors d'interventions semblables exécutées dans une salle d'opération principale dotée d'interventions de stérilisation standard. Ainsi, la mise en Åuvre de cette technique pourrait améliorer le déroulement du travail et réduire le gaspillage, tout en maintenant la sécurité du patient.
