Effects of Postoperative Splinting on Outcomes following Digital Mucous Cyst Excision: A Retrospective Review.

Background: Digital mucous cysts (DMCs) are masses on the fingers that can be definitively managed with surgical excision. Though uncommon, surgical site infections can develop into septic arthritis. We sought to determine whether postoperative splinting decreases rates of postoperative infection and the need for postoperative antibiotics. We also explored the effect of age, gender, obesity, and preoperative antibiotic administration on infectious complications. Methods: Patients who underwent DMC excision between 2011 and 2021 were retrospectively identified. Chi-squared and Fisher's exact tests were used to analyze the complication rates including documented infection, postoperative antibiotic administration, mass recurrence, and return to operating room. Associations were analyzed between both preoperative antibiotic administration and postoperative splinting with respect to postsurgical complications. Results: The database search identified 373 patients who underwent 394 DMC excisions. Postoperative antibiotics were given in splinted patients at lower rates than their nonsplinted counterparts with a small-to-moderate effect size, but the difference was not statistically significant (2.7 vs. 7.5%). Preoperative antibiotic administration was not found to significantly affect the prescription of postoperative antibiotics. Splinting did not reduce rates of DMC recurrence. Patients who were splinted were more likely to have also received preoperative antibiotics. Males were given postoperative antibiotics more frequently than females (12.6 vs. 4.0%). Conclusions: Though not statistically significant, splinted patients were prescribed postoperative antibiotics less frequently. Postoperative antibiotics were utilized more frequently than the rate of infections typically reported following this procedure, possibly indicating overcautious prescription habits or underreported suspected infections.

Evaluation of Patient Expectations and Outcomes after Distal Radius Fractures.

BACKGROUND: Patient expectations influence patient-reported outcomes after musculoskeletal injuries. The goal of this study is to determine how pretreatment expectations correlate with outcomes in patients with distal radius fractures. METHODS: Seventy-five patients with an isolated distal radius fracture were prospectively enrolled into nonoperative and operative cohorts. The Trauma Expectation Factor-Trauma Outcome Measure (TEF-TOM) score was the primary outcome measure. Trauma Expectation Factor scores were recorded at the time of enrollment, and TOM scores were recorded at 3, 6, and 12 months. Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) and Patient-Rated Wrist Evaluation (PRWE) scores were also recorded. RESULTS: Trauma Outcome Measure scores at all time points were worse than expected (P < .01). Expectations were higher for patients younger than 65 years than for the 65+ group (P = .02). In patients aged 65+ years, mean TOM at 3 months was not significantly different than expected (P = .11) but decreased by 6 (P = .04) and 12 months (P < .01). Baseline TEF and TEF-TOM scores were not significantly different between operative and nonoperative groups (P = .37). Quick Disabilities of the Arm, Shoulder, and Hand and PRWE scores were not significantly different between age or treatment groups at the final follow-up. CONCLUSIONS: The overall treatment of distal radial injuries in our study did not meet patient expectations. Patients aged 65 years or older had lower expectations but were not able to predict their outcomes better than patients aged <65 years. There were no differences in TEF or TOM by treatment method. Patients demonstrated improved functional outcomes (qDASH/PRWE) at all time points regardless of age and treatment method.

Long-term Efficacy of Corticosteroid Injection for Carpal Tunnel Syndrome: A Systematic Review.

Carpal tunnel syndrome (CTS) is a debilitating condition that can cause significant morbidity. Corticosteroid injection (CI) is a popular treatment for CTS. Short-term benefits of CI for CTS have been reported, but there is little evidence on long-term outcomes. We performed a systematic review in the PubMed/MEDLINE and Cochrane Library databases to identify studies which reported outcomes of CI for CTS with at least 1-year follow-up. We identified 20 total studies and extracted data on outcomes such as number of patients needing eventual surgery or reinjection, complications, and functional scores. In included studies, 41.6% of patients underwent eventual carpal tunnel release surgery (CTRS), 29% underwent reinjection, there were no major and approximately 34/1133 (3.0%) minor complications, and median/mean time from CI to eventual CTRS ranged from 128 to 446 days. There was disparity on the long-term efficacy of CI for functional outcomes. The evidence indicates that CI is a very low risk procedure that has potential to improve symptoms enough to either prevent or, in most cases, delay the need for further reintervention. However, our conclusions are limited by the heterogeneity of available studies. There is a need for further, high-quality research on this topic.

Management of Isolated Ulnar Shaft Fractures.

¼ Most isolated ulnar shaft fractures are stable and heal without complication regardless of treatment protocol.¼ Casting above the elbow may create unwanted stiffness without enhancing union rates.¼ Defining unstable fractures and determining which injuries would benefit from operative management remain a challenge.¼ Recent development of intramedullary devices has shown promise in preliminary studies, but more vigorous investigation is needed to determine their role.

Distal Intersection Syndrome Between Second and Third Dorsal Compartments of the Wrist.

Distal intersection syndrome (DIS) is a rare form of tenosynovitis affecting the second and third dorsal extensor compartments of the wrist, which is rarer and more distal than the classically described intersection syndrome between the first and second compartments. In this report, we present three cases of DIS, their inciting activities, and ensuing treatment courses. Diagnosis of DIS was confirmed via MRI in all cases. Treatment modalities consisted of non-steroidal anti-inflammatory medications and varying durations of immobilization in all three patients, initially. One patient ultimately underwent surgical debridement and partial tenosynovectomy. At the end of follow-up, all patients saw a reduction in symptomatology with a return to baseline activity levels. This case report provides an overview of the possible clinical courses of DIS, as well as treatment strategies that can be implemented. Providers must maintain a high index of suspicion for this condition and treat patients with a great deal of caution, as extensor tendon rupture is possible.

Case report: Multiple sclerosis diagnosis after anterior lumbar interbody fusion and presumed COVID-19 infection.

Background: Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system that may present with a wide variety of clinical presentations. However, there can be substantial overlap between symptoms from MS and those caused by lumbar spondylosis and/or postviral plexopathies. Case Description: A 33-year-old female with a history of an L5-S1 anterior lumbar interbody fusion and exposure to the SARS-CoV-2 virus developed postoperative worsening of her symptoms interpreted as "radiculopathy." Despite a subsequent L5-S1 fusion, she continued to neurologically deteriorate and was ultimately diagnosed with MS. Conclusion: The initial symptoms/signs of MS may mimic lumbar radiculopathy and or postviral plexopathy (i.e., due to recent COVID-19). This report should serve as a warning to future spinal surgeons to better differentiate between radicular and other "complaints," sufficient to avoid unnecessary repeated spinal surgery.

Reduction Techniques in Volar Locking Plate Fixation of Distal Radius Fractures.

Distal radius fractures are the most common upper extremity fracture and volar locking plate fixation has become a common modality for operative management of these injuries over the last 2 decades. However, despite the widespread use of volar locking plates, there remains no comprehensive guide detailing the available reduction techniques using these systems. This review aims to consolidate the reduction techniques from the literature along with the authors' experiences into a blueprint for distal radius fracture reduction when using a volar plate. Techniques described include those with and without use of the plate and with supplementary means of fixation for both extra-articular and intra-articular fracture patterns.

Novel Method for Reduction of Distal Radius Fractures.

SUMMARY: Distal radius fractures are one of the most common fractures seen in orthopaedics. These fractures may be treated surgically or conservatively depending on patient-related and radiographic factors. Displaced fractures should be reduced in the acute setting to better align the fracture fragments and a splint applied to hold the fracture in this position. Fractures that are acceptably reduced may be treated conservatively with casting and close radiographic follow-up to ensure maintained alignment. In this video, we describe our technique for closed reduction of distal radius fractures and review important factors that guide treatment.

Complications of Volar Plating of Distal Radius Fractures: A Systematic Review.

Background In recent years, there has been an increased utilization of volar locking plate fixation of distal radius fractures (DRFs). However, reported long-term complication rates with this technique remain unclear. Purpose The purpose of this systematic review was to investigate the pooled incidence of complications associated with volar locking plating of DRF. Methods A search of the Scopus database was performed from 2006 through 2016. Studies were considered eligible if they had a diagnosis of a DRF and were treated with a volar locking plate with an average of 12 months or longer follow-up. Results The literature search yielded 633 citations, with 55 eligible for inclusion in the review (total n = 3,911). An overall complication rate of 15% was identified, with 5% representing major complications requiring reoperation. The most common complication types identified included nerve dysfunction (5.7%), tendon injury (3.5%), and hardware-related issues (1.6%). Conclusion Nerve complications were reportedly higher than tendon and hardware-related complications combined. However, despite varying complication rates in the literature, this systematic review reveals an overall low complication rate associated with volar locking plating of DRF.

A Cost Analysis of Carpal Tunnel Release Surgery Performed Wide Awake versus under Sedation.

BACKGROUND: Hand surgery under local anesthesia only has been used more frequently in recent years. The purpose of this study was to compare perioperative time and cost for carpal tunnel release performed under local anesthesia ("wide-awake local anesthesia no tourniquet," or WALANT) only to carpal tunnel release performed under intravenous sedation. METHODS: A retrospective comparison of intraoperative (operating room) surgical time and postoperative (postanesthesia care unit) time for consecutive carpal tunnel release procedures performed under both intravenous sedation and wide-awake local anesthesia was undertaken. All operations were performed by the same surgeon using the same mini-open surgical technique. A cost analysis was performed by means of standardized anesthesia billing based on base units, time, and conversion rates. RESULTS: There were no significant differences between the two groups in terms of total operative time, 28 minutes in the intravenous sedation group versus 26 minutes in the wide-awake local anesthesia group. Postanesthesia care unit times were significantly longer in the intravenous sedation group (84 minutes) compared to the wide-awake local anesthesia group (7 minutes). Depending on conversion rates used, a total of $139 to $432 was saved in each case performed with wide-awake local anesthesia by not using anesthesia services. In addition, a range of $1320 to $1613 was saved for the full episode of care, including anesthesia costs, operating room time, and postanesthesia care unit time for each patient undergoing wide-awake local anesthesia carpal tunnel release. CONCLUSION: Carpal tunnel release surgery performed with the wide-awake local anesthesia technique offers significant reduction in cost for use of anesthesia and postanesthesia care unit resources.

A Prospective Randomized Study Comparing Bupivacaine Hydrochloride Versus Bupivacaine Liposome for Pain Management After Distal Radius Fracture Repair Surgery.

PURPOSE: To compare pain experience and opioid use after distal radius fracture repair surgery performed with perioperative infiltration of the local anesthesia bupivacaine hydrochloride (Marcaine; Pfizer, New York, NY) or bupivacaine liposome (Exparel; Pacira, Parsippany, NJ). METHODS: We conducted a prospective comparison of consecutive patients scheduled to undergo distal radius fracture repair surgery. Patients were randomized to either Marcaine or Exparel. Patients in the Marcaine group received 20 mL 0.5% bupivacaine without epinephrine into the incision and surgical site before incision. Patients in the Exparel group first received 10 mL 0.5% Marcaine with no epinephrine into the incision and surgical site before incision; then, upon completion of the surgery and wound closure, they also received 10 mL Exparel into the same site that had been preinjected with Marcaine. All operations were performed with the same surgical technique. Daily opioid pill consumption, pain levels, and any adverse reactions were recorded from postoperative days 0 to 5. RESULTS: On the day of surgery, patients in the Exparel group reported significantly lower pain levels (3.9 vs 5.8) and consumed significantly fewer prescribed opioid pills (1.2 vs 2.0) compared with patients in the Marcaine group. However, there were no other significant differences between the Exparel and Marcaine groups on any subsequent days or in the total number of pills consumed at the end of the study period (7.5 vs 8.9 pills, respectively). No major adverse reactions were noted in either group. CONCLUSIONS: Exparel use was found to result in decreased pain and opioid consumption only on the day of surgery and not thereafter. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

A Prospective Randomized Study Analyzing Preoperative Opioid Counseling in Pain Management After Carpal Tunnel Release Surgery.

PURPOSE: Prescription opioid misuse has become increasingly prevalent in the United States. Preoperative opioid counseling has been proposed to decrease opioid consumption after surgery. This study aimed to evaluate the effect of preoperative opioid counseling on patients' pain experience and opioid consumption after carpal tunnel release (CTR) surgery. METHODS: A prospective comparison of consecutive patients scheduled to undergo CTR surgery was conducted. Patients were randomized to receive either formal preoperative opioid counseling or no counseling. All operations were performed with the same mini-open CTR surgical technique, and the same number of opioids were prescribed after surgery. Daily opioid pill consumption, pain levels, and any adverse reactions were recorded. RESULTS: During the day of surgery and the first day following surgery, patients in the group with counseling reported significantly fewer prescribed opioid pills consumed compared with patients in the group without counseling, while experiencing no significant difference in pain level experience. In addition, patients in the group with counseling reported a significantly lower number of total pain pills consumed over the course of the study than the group without counseling. No major adverse reactions were noted in either group. CONCLUSIONS: Preoperative opioid counseling was found to result in a significant decrease in overall opioid consumption after surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Classification of atherosclerotic rabbit aorta samples with an infrared attenuated total reflection catheter and multivariate data analysis.

The strongly overlapping infrared absorption features of atherosclerotic and normal rabbit aorta samples as governed by their water, lipid, and protein content render the direct evaluation of molecular characteristics obtained from infrared (IR) spectroscopic measurements challenging for classification. We have successfully applied multivariate data analysis and classification techniques based on partial least squares regression (PLS), linear discriminant analysis (LDA), and principal component regression (PCR) to IR spectroscopic data obtained by using a recently developed infrared attenuated total reflectance (IR-ATR) catheter prototype for future in vivo diagnostic applications. Training data were collected ex vivo from atherosclerotic and normal rabbit aorta samples. The successful classification results on atherosclerotic and normal aorta samples utilizing the developed data evaluation routines reveals the potential of spectroscopy combined with multivariate classification strategies for the identification of normal and atherosclerotic aorta tissue for in vitro and, in the future, in vivo applications.

Catheter for diagnosis and therapy with infrared evanescent waves.

We have developed an optical delivery device (catheter) capable of transmitting broadband infrared light (IR wavelengths from 2 to 10 microm) for both diagnostic and therapeutic applications. The catheter is 1.68 mm in outer diameter and 1 m in length. It consists of two hollow glass waveguides coupled to a high-refractive-index optic tip. The IR light interacts with the tissue at the optic-tissue interface to measure the spectral signatures and perform therapy on the tissue at this interface. Fourier-transform IR spectrophotometer light is used to obtain the spectral signatures, and an IR free-electron laser (FEL) is used to study the therapeutic interaction of evanescent waves with the tissue. We present our catheter design; preliminary IR spectroscopy of aorta, blood, fatty tissue, and muscle; and IR FEL therapy on atheroslerotic aorta.
