Office-Based Carpal Tunnel Release With Ultrasound Guidance: 6-month Outcomes From the Multicenter ROBUST Trial.

Purpose: The purpose of this study was to determine the safety and effectiveness of office-based carpal tunnel release with ultrasound guidance (CTR-US). Methods: In this prospective multicenter observational study, patients were treated with CTR-US in an office setting. Outcomes were time to resume normal daily activities, time to return to work, Boston Carpal Tunnel Questionnaire Symptom Severity Scale and Functional Status Scale scores, Michigan Hand Questionnaire, Numeric Pain Scale, EuroQoL-5 Dimension 5-Level score, procedure satisfaction, and adverse events over 6 months. Results: A total of 149 participants (226 hands) from seven centers underwent office-based CTR-US. The mean age was 58 years, 52% were women, and 68% were employed. The mean incision length was 5 mm, 52% had simultaneous bilateral procedures, and wide-awake local anesthesia no tourniquet was used in all cases. All procedures were completed as planned, with no conversions to open repair and mean intraoperative pain severity of 1.6 ± 1.5. The median time to resume normal activities was 2 days (interquartile range: 1-4 days) and return to work was 4 days (interquartile range: 1-5 days). Over 6 months, Boston Carpal Tunnel Questionnaire Symptom Severity Scale decreased by a mean of 1.7 points, Boston Carpal Tunnel Questionnaire Functional Status Scale decreased by 1.1 points, Michigan Hand Questionnaire Global score increased by 35 points, Numeric Pain Scale decreased by 3.7 points, and EuroQoL-5 Dimension 5-Level score increased by 0.11 points. At 6 months, 94% reported procedure satisfaction. Unilateral and simultaneous bilateral procedures were similarly effective. There was one (0.4%) adverse event, a nerve contusion treated with neurolysis and nerve wrap where the patient fully regained normal function within 7 weeks. There were no revisions for persistent or recurrent carpal tunnel syndrome symptoms. Conclusions: Office-based CTR-US, performed either unilaterally or as simultaneous bilateral procedures, is well tolerated with a low complication rate and associated with rapid recovery, sustained improvement in symptoms and function, and high procedure satisfaction. Type of study/level of evidence: Therapeutic III.

Long-Term Clinical Results of Carpal Tunnel Release Using Ultrasound Guidance: A Multicenter Pragmatic Study.

Purpose: The purpose of this study was to report the 1-year clinical outcomes of carpal tunnel release using ultrasound guidance (CTR-US) performed in a large, real-world population of patients enrolled in a multicenter registry. Methods: All patients who participated in a postmarket registry study of CTR-US outcomes and provided both preoperative and 1-year postoperative data were included. Main outcomes were the Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire (QDASH), Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS), and Boston Carpal Tunnel Functional Status Scale (BCTQ-FSS) scores at 1 year. Subgroup analysis was performed to assess the effect of patient and procedural factors on 1-year outcomes. Results: A total of 300 patients (341 hands) were treated by 25 different physicians, including 41 (13.7%) treated with simultaneous bilateral procedures. Mean patient age was 54.2 years, 63% were women, 24% had ≥2 comorbidities, and 54% had symptoms for >2 years. Mean QDASH scores decreased from 40.6 ± 20.6 to 12.2 ± 18.3 at 1 year, BCTQ-SSS scores decreased from 3.0 ± 0.7 to 1.5 ± 0.7 at 1 year, and BCTQ-FSS scores decreased from 2.4 ± 0.8 to 1.4 ± 0.6 at 1 year. Women improved more than men at 1 year for QDASH, BCTQ-SSS, and BCTQ-FSS. Patients treated with simultaneous bilateral procedures had similar 1-year outcomes to those treated with unilateral procedures. Multiple other factors including high body mass index, diabetes status, current tobacco use, rheumatoid/inflammatory arthritis, operation in the dominant hand, higher comorbidity burden, and concurrent ipsilateral procedures did not significantly affect 1-year outcomes. Two patients had revision surgeries in addition to one patient with an infection, and one with a suspected small finger tendon injury. Conclusions: Patients treated with CTR-US in real-world conditions report significant and clinically meaningful improvements in symptoms and function that are maintained at 1 year. The results are consistent across broad patient demographics and are not affected by performing simultaneous bilateral procedures. Type of study/level of evidence: Therapeutic IV.

Early Return to Work after Carpal Tunnel Release with Ultrasound Guidance.

Background: The duration of postoperative leave varies by the carpal tunnel release (CTR) technique. This study aimed to determine the time to return to work (RTW) after CTR with ultrasound (CTR-US) guidance and identify factors contributing to this duration. Methods: This was a multicenter postmarket registry of patients treated with CTR-US. Time to RTW was analyzed with Kaplan-Meier methods. Logistic regression identified the association of patient, work, and procedural factors with the probability of RTW within 5 days (a standard work week) after CTR-US. Results: A total of 544 employed patients (655 hands) from 24 centers were treated with CTR-US between November 2019 and August 2022. The mean patient age was 50 years, 62% were women, and most (76%) were full-time employees, where work activities were desk-based (49%), light manual (28%), or heavy manual (23%). The complication rate was 0.8%. After CTR-US, the median RTW was 3 days (interquartile range: 1-6 days), with 74.6% returning by 5 days, 87.8% by 10 days, and 97.1% by 30 days. Work activity (desk-based versus heavy manual: odds ratio = 2.93, 95% confidence interval: 1.70-5.04, P < 0.001) and sex (man versus woman: odds ratio = 1.85, 95% confidence interval: 1.15-2.98, P = 0.01) were associated with higher probability of RTW within 5 days. The median RTW ranged from 2 to 4 days in all patient subgroups, including heavy manual laborers (median 4 days) and women (median 3 days). Conclusions: CTR-US offers an efficient approach to treating CTS, enabling most patients to RTW with minimal delay. The short recovery periods observed across diverse patient and work characteristic subgroups compare favorably to other CTR techniques.

Technique for Insertion of the Conventus Cage for Distal Radial Fracture Fixation.

INTRODUCTION: Use of the intramedullary Conventus DRS Cage and fragment-specific screw fixation of distal radial fractures minimizes soft-tissue trauma, leading to earlier and improved wrist and finger motion while reducing traditional complications seen with internal fixation of distal radial fractures. STEP 1 REDUCE THE FRACTURE: Reduce the fracture with closed or, if necessary, open methods to achieve anatomic restoration of articular congruity, radial inclination, radial length, volar tilt, and coronal shift. STEP 2 PROVISIONALLY STABILIZE THE FRACTURE: Provisionally stabilize the reduced fracture for insertion of the cage and fragment-specific screws with either longitudinal finger-trap traction or longitudinal Kirschner wires. STEP 3 PREPARE FOR CAGE FIXATION: Prepare the distal part of the radius for cavity preparation and insertion of the Conventus DRS Cage. STEP 4 INSERT THE CONVENTUS DRS CAGE: Insert the previously chosen small or large Conventus DRS Cage. STEP 5 FIX THE FRACTURE FRAGMENTS: Anatomically fix the fracture fragments to the cage and radial shaft. STEP 6 CONFIRM FRACTURE STABILITY: Move the wrist through a full range of motion while assessing fluoroscopically whether the fracture has been stabilized with the cage-and-screw construct. STEP 7 CLOSE THE WOUND: Close the skin incision and cutdown wounds and apply dressings. RESULTS: The Conventus DRS Cage has been used for treatment of distal radial fractures in the U.S. for >3 years.

Secondary Alveolar Bone Grafting (CLEFTSiS) 2007-2010.

Objective To determine whether alveolar bone graft outcomes for unilateral and bilateral cleft lip and palate patients have continued to improve since the reorganization of cleft services in Scotland in 2000. Design Retrospective analysis of postoperative anterior occlusal radiographs. Patients and Participants Eighty-one of 106 patients who were eligible for alveolar bone grafting between 2007 and 2010 had suitable postoperative radiographs available. Interventions Twenty-seven percent of the patients (n = 22) had presurgical orthodontic intervention. All patients underwent alveolar bone grafting with bone harvested from the iliac crest. Main Outcome Measures The Kindelan bone-fill index was used to evaluate success. Weighted kappa statistics were used to assess intra- and interobserver reproducibility. A comparison was made with results from 2000 to 2004 to assess any improvement. Chi-square tests (or Fisher exact test) were used to determine whether outcomes differed depending on the laterality of the cleft, use of presurgical expansion, or age at bone grafting. Results Interobserver scoring agreement was good (weighted kappa = .383). Intraobserver reproducibility was greater (weighted kappas of .835 and .620). Success was achieved in 99% of bone grafts, compared with 76% in the period from 2000 to 2004 (P < .001). There was no statistically significant relationship between the laterality of the cleft (P = 1.000), use of presurgical expansion (P = 1.000), or age at time of bone grafting and outcome (P = .259). Conclusion Scottish secondary alveolar bone graft outcomes improved during 2007 to 2010 in comparison to the 2000 to 2004 results.

The importance of early intervention in the treatment of dental infection.

UNLABELLED: With recent reports of increasing hospital admissions relating to dental infection, the authors believe it is time to re-visit the importance of its effective early treatment. A series of three cases is used to illustrate the potentially life-threatening progression of what, in the early stages, is an easily treatable condition. CLINICAL RELEVANCE: The principles of effective management of dental infection are highlighted in the first instance and then indications for specialist maxillofacial referral are discussed.

Hemiarthroplasty of the distal humerus for acute and chronic complex intra-articular injuries.

BACKGROUND: Comminuted intra-articular distal humeral fractures represent a challenging upper extremity injury. This study reviews clinical and radiographic results in patients with distal humeral hemiarthroplasty (DHH). METHODS: DHH with the Latitude prosthesis (Tornier, Saint-Ismier, France) was performed in 8 patients (mean age, 64 years; age range, 33-75 years) for unreconstructible fractures of the distal humerus or salvage of failed internal fixation. Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons elbow instrument; Mayo Elbow Performance Index; and Disabilities of the Arm, Shoulder and Hand questionnaire at a mean of 36 months. Radiologic assessment included radiographs and computed tomography to evaluate olecranon wear and densitometry (dual-energy x-ray absorptiometry). Range of motion, pain, and elbow satisfaction were recorded, and descriptive statistics were used for analysis. RESULTS: Seven patients were available to participate in the follow-up examination. Acute cases (5 patients) scored better than salvage cases (2 patients) on the Mayo Elbow Performance Score (80 points [range, 67-95 points] and 65 points [range, 50-80 points], respectively) and Disabilities of the Arm, Shoulder and Hand score (31 points [range, 2.5-68 points] and 39 points [range, 17-62 points], respectively). The mean arc of elbow flexion and extension was 96° (range, 70°-130°), with mean flexion of 120° (range, 90°-135°) and a mean extension loss of 19° (range, 5°-30°). The mean arc of forearm rotation was 160° (range, 140°-180°). Reoperation was required in 4 patients because of painful retained hardware. Five patients reported pain with activities of daily living. CONCLUSION: DHH should be used with caution until such time as longer-term outcome studies are able to show the efficacy of this procedure.

Cleft lip/palate: incidence of prenatal diagnosis in Glasgow, Scotland, and comparison with other centers in the United Kingdom.

OBJECTIVES: To determine the proportion of children with cleft lip and/or cleft palate diagnosed prenatally between 1999 and 2008 in those referred for treatment to the Royal Hospital for Sick Children in Glasgow, Scotland (RHSC); and to compare the percentage prenatally diagnosed in 2008 versus other cleft treatment centers in the U.K. METHOD: A retrospective study was performed using medical records of the 459 cleft patients born and referred to RHSC between 1999 and 2008. Comparable data for year 2008 were requested from other U.K. units. RESULTS: For the period studied, the percentage of all clefts diagnosed prenatally was 15%. This rose to 28% when only the cases of cleft lip with or without cleft palate (CL ± P) were considered. An increase was seen in prenatal detection of CL ± P from 11% in 1999 to 50% in 2008 (p = .011). Two of the six U.K. units that responded had a significantly higher percentage of CL ± P cases diagnosed prenatally compared with RHSC in 2008 (p < .05). CONCLUSIONS: The percentage of CL ± P cases diagnosed prenatally in this study is consistent with the literature and increased between 1999 and 2008. Routine ultrasound anomaly scanning is shown to significantly improve detection rates compared with scanning of high-risk pregnancies only. Cases of CL ± P where the alveolus or the palate is involved have significantly higher detection rates than those involving only the lip.

Blood lactate clearance during active recovery after an intense running bout depends on the intensity of the active recovery.

High-intensity exercise training contributes to the production and accumulation of blood lactate, which is cleared by active recovery. However, there is no commonly agreed intensity or mode for clearing accumulated blood lactate. We studied clearance of accumulated blood lactate during recovery at various exercise intensities at or below the lactate threshold after high-intensity interval runs that prompted lactate accumulation. Ten males repeated 5-min running bouts at 90% of maximal oxygen uptake (VO(2max)), which increased blood lactate concentration from 1.0 +/- 0.1 to 3.9 +/- 0.3 mmol l(-1). This was followed by recovery exercises ranging from 0 to 100% of lactate threshold. Repeated blood lactate measurements showed faster clearance of lactate during active versus passive recovery, and that the decrease in lactate was more rapid during higher (60-100% of lactate threshold) than lower (0-40% of lactate threshold) (P < 0.05) intensities. The more detailed curve and rate analyses showed that active recovery at 80-100% of lactate threshold had shorter time constants for 67% lactate clearance and higher peak clearance rates than 40% of lactate threshold or passive recovery (P < 0.05). Finally, examination of self-regulated intensities showed enhanced lactate clearance during higher versus lower intensities, further validating the intensity dependence of clearance of accumulated blood lactate. Therefore, active recovery after strenuous exercise clears accumulated blood lactate faster than passive recovery in an intensity-dependent manner. Maximum clearance occurred at active recovery close to the lactate threshold.
