Abstract
Ultrasound and magnetic resonance neurography are useful modalities to aid in the assessment of compressive neuropathies, although they are still limited in their resolution of nerve microstructure and their capacity to monitor postoperative nerve recovery. Optical coherence tomography, a preclinical imaging modality, is promising in its ability to better identify structural and potential physiologic changes to peripheral nerves, but requires additional testing and research prior to widespread clinical implementation. Further advances in nerve imaging may elucidate the ability to visualize the zone of nerve injury intraoperatively, monitor the progression of nerve regeneration, and localize problems during nerve recovery.

[PMID: 38106929 PMCID: PMC10721515 DOI: 10.1016/j.jhsg.2023.07.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 07/15/2023] [Indexed: 12/19/2023] Open
Abstract
Purpose The aim of this systematic review and meta-analysis was to evaluate the safety and effectiveness of endoscopic carpal tunnel release (ECTR) using best-evidence synthesis methods. Methods A systematic search of multiple databases was conducted for prospective contemporary studies published between January 2013 and January 2023 with at least 50 ECTR cases. Outcomes included the Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire (Q-DASH) measured on a 0-100 scale, Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) and Functional Status Scale (BCTQ-FSS) on a 1-5 scale, pain visual analog scale on a 0-10 scale, conversion to open carpal tunnel release (CTR), complications, and reoperations. Outcomes were analyzed using a random-effects meta-analysis model. Metaregression was used to determine the association of patient- and study-level factors with ECTR outcomes. Results A total of 17 studies with 1,632 patients treated with ECTR were included. Median follow-up durations ranged from 4 to 7 months depending on the outcome. Statistically significant and clinically important improvements were noted after ECTR for Q-DASH, BCTQ-SSS, BCTQ-FSS, and pain visual analog scale scores, with mean differences from baseline of -28.8, -1.8, -1.5, and -5.1, respectively (P < .001 for all). In metaregression, the strongest predictor of improvement in Q-DASH, BCTQ-SSS, and BCTQ-FSS was a greater preoperative score for that variable (all P ≤ .005), indicating that patients with worse symptoms improved the most. The risks of conversion to open CTR, complications, and revision CTR were 0.7%, 0.7%, and 0.5%, respectively. Conclusions In a best-evidence synthesis of contemporary studies, ECTR resulted in significant improvements in function and pain, with a low risk of conversion to open surgery, complications, and reoperations over short-term follow-up. Clinical relevance Patients treated with ECTR can expect generally favorable clinical outcomes over the short term. However, long-term outcomes after ECTR are not well characterized.

Abstract
Background Carpal tunnel release (CTR) is a common surgical procedure for patients with severe or refractory carpal tunnel syndrome (CTS) symptoms. Historically, CTR procedures have been performed in a hospital or an ambulatory surgery center (ASC). However, due to advancements in techniques, greater patient demand, and concerns about growing healthcare costs, there is a distinct trend toward performing CTR procedures in an office-based setting. Several small studies with limited follow-up duration have demonstrated the feasibility of CTR with ultrasound guidance (CTR-US) when performed in an office-based setting. The objective of this study is to evaluate the safety and effectiveness of office-based CTR-US in a large cohort of patients (n=140) with symptomatic CTS followed for two years post-treatment. Design and methods ROBUST is a prospective multicenter observational study in which 140 subjects at up to 12 sites in the United States will be treated with CTR-US in an office-based setting. The primary endpoint of the study is the change in the Boston Carpal Tunnel Questionnaire Symptom Severity Scale score. Secondary endpoints include time to return to normal daily activities, time to return to work among employed subjects, change in the Boston Carpal Tunnel Questionnaire Functional Status Scale score, change in the Michigan Hand Questionnaire overall and domain scores, change in the Numeric Pain Scale score, change in the EuroQoL-5 Dimension 5-Level score, global satisfaction scores, and the incidence of device or procedure-related adverse events. The primary analysis of study endpoints will occur three months post-treatment. Patient follow-up in this study will continue for two years. Conclusions A central institutional review board approved the study protocol, and a data safety monitoring board will provide study oversight. The authors plan to report study results at medical conferences and in peer-reviewed medical journals. The outcomes of ROBUST will provide physicians, patients, and payors with important safety and effectiveness data regarding the clinical utility of CTR-US when performed in an office setting.

Abstract
PURPOSE To develop a new computer adaptive test that evaluates important aspects of medication adherence for persons with type 2 diabetes mellitus. METHODS Two hundred and twenty-five people with type 2 diabetes mellitus completed 41 items related to medication adherence. RESULTS Exploratory analysis supported the essential unidimensionality of the initial item pool. Five items were deleted due to low item-adjusted total score correlations (resulting in 36 items). Confirmatory factor analysis supported the retention of 27 items. A graded response model identified no items for exclusion, based on misfit. No items were flagged for meaningful differential item functioning (DIF). The final item bank is comprised of 27 items; an associated 6-item short form was constructed that balanced both psychometric factors (e.g., item information values) and clinical input. Initial analysis of the simulated CAT and static short form supported both the reliability (i.e., internal consistency and test-retest reliability) and validity (i.e., convergent, discriminant, and known groups) of both administration formats. CONCLUSIONS The new medication adherence item bank provides a reliable and valid assessment of the ability to take medications accurately among people with T2DM; it will be available in early 2023 through healthmeasures.net.

Abstract
PURPOSE Local steroid injection is an effective treatment modality for carpal tunnel syndrome. This study aimed to investigate the success rate of ultrasonography-guided local steroid injection and determine the prognostic value of the cross-sectional area (CSA) of the median nerve for steroid injection. METHODS We retrospectively evaluated 40 patients with carpal tunnel syndrome whose median nerve CSA was >15 mm2 (large-CSA group; n = 16) or ≤15 mm2 (small-CSA group; n = 24). The CSA was measured using ultrasonography, and all the patients were treated with ultrasonography-guided corticosteroid injection. Demographic characteristics, symptoms, initial QuickDASH score, Boston Carpal Tunnel Questionnaires, and results of the nerve conduction study were assessed at baseline. Treatment success was defined in this study as the absence of symptom recurrence within the entire follow-up period. RESULTS The treatment success rate was 45% (n = 18) after an average follow-up of 16 months. Overall, 11 patients (28%) underwent carpal tunnel release on an average of 11 months after steroid injection. The large-CSA group showed a significantly worse grade of electrodiagnostic testing at baseline than did the small-CSA group; however, there was no significant difference in final Boston Carpal Tunnel Questionnaires symptom score (1.7 vs 1.8, respectively) and the rate of continued treatment success at the last follow-up (42% vs 50%, respectively). The proportions of patients who required carpal tunnel decompression were 29% and 25% in the small-CSA and large-CSA groups, respectively. CONCLUSIONS Local steroid injection for carpal tunnel syndrome has an overall success rate of 45% after a mean follow-up of 16 months. Preinjection CSA was not associated with whether the steroid injection was considered successful. This indicates that increased median nerve CSA does not preclude the possibility of symptomatic relief after a local steroid injection. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND The interest in ultrasonography (US) and magnetic resonance imaging (MRI) assessment of the patients with carpal tunnel syndrome (CTS) is growing. This paper aimed to find the correlation of postoperative changes in these modalities' parameters with clinical outcomes. METHODS Boston CTS questionnaire-symptom severity (BQ-SS), Boston CTS questionnaire-functional status (BQ-FS), and visual analog scale (VAS) questionnaires (for pain, paresthesia, and grip weakness assessment) were used to evaluate clinical outcomes. Various imaging parameters of the median nerve and carpal tunnel were evaluated using US and MRI at two levels of the hook of the hamate (distal) and the pisiform (proximal) once preoperatively and then 3 months postoperatively. Corresponding US and MRI parameter measures were compared, and correlational analysis was performed between alteration of imaging findings and changes in clinical parameters postoperatively. RESULTS Patients' functional status (BQ-FS score) was positively correlated with the nerve width both in US and MRI at the proximal level (r = 0.457 and r = 0.453, respectively) and also with the MRI nerve circumference at the distal level (r = -0.482). Correlation between paresthesia and the nerve width was notable in MRI at the distal hook of the hamate level (r = -0.403). Grip weakness VAS score was correlated with the nerve width-to-height ratio (WHR) in US at the distal level (r = 0.432). CONCLUSIONS Changes in US and MRI parameters of the median nerve width, circumference, and WHR were associated with clinical changes in patients with CTS after surgery.

Abstract
Compressive neuropathies of the upper extremity are among the most common conditions seen by hand surgeons. The diagnoses of carpal tunnel syndrome and cubital tunnel syndrome have traditionally been made by a combination of history, physical examination, and electrodiagnostic testing. However, findings can be nonspecific and electrodiagnostic testing is invasive for the patient. The diagnosis of compressive neuropathies continues to evolve as technology advances, and newer diagnostic modalities predominantly focus on preoperative diagnostic imaging with ultrasound and magnetic resonance imaging/neurography. With the advent of cheaper, faster, and less invasive imaging, the future may bring a paradigm shift away from electrophysiology as the gold standard for the preoperative diagnosis of compressive neuropathies. Intraoperative imaging of nerve health is an emerging concept that warrants further investigation, whereas postoperative imaging of nerve recovery with ultrasound and magnetic resonance imaging currently has a limited role because of nonspecific findings and potential for misinterpretation. Advances in surgical treatment of compressive neuropathies appear to center around the use of imaging for less invasive neurolysis techniques and other adjunctive treatments with nerve decompression. The management of failed peripheral nerve decompressions and recurrent compressive neuropathies remains challenging.

Abstract
BACKGROUND Carpal tunnel release (CTR) is a surgical treatment option for patients with carpal tunnel syndrome (CTS) symptoms that are unresponsive to conservative treatment. Most patients experience symptomatic relief after CTR regardless of the surgical technique. However, direct comparisons of the safety and effectiveness between CTR surgical techniques are limited. The purpose of this randomized controlled trial is to compare the safety and effectiveness of CTR with ultrasound guidance (CTR-US) versus mini-open CTR (mOCTR) in subjects with symptomatic CTS. DESIGN AND METHODS TUTOR (Trial of Ultrasound guided CTR versus Traditional Open Release) is a randomized controlled trial in which 120 subjects at up to 12 sites in the United States will be randomized (2:1) to receive CTR-US or mOCTR. The primary endpoint of the study is the percentage of patients who return to normal daily activities within 3 days of the procedure. Secondary endpoints of the study are median time to return to normal daily activities, percentage of patients who return to work within 3 days of the procedure, median time to return to work, Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) change score at 3 months, BCTQ Functional Status Scale (BCTQ-FSS) change score at 3 months, Numeric Pain Scale change score at 3 months, EuroQoL-5 Dimension 5-Level (EQ-5D-5L) change score at 3 months, and the incidence of device- or procedure-related adverse events at 3 months. Patient follow-up in this trial will continue for 1 year. ETHICS AND DISSEMINATION This study was approved by a central institutional review board and ongoing trial oversight will be provided by a data safety monitoring board (DSMB). The authors intend to report the results of this trial at medical conferences and peer-reviewed journals. The outcomes of TUTOR will have important clinical and economic implications for all stakeholders involved in treating patients with CTS.

Abstract
Background The gold standards for the diagnosis and treatment of carpal tunnel syndrome (CTS) and its outcome are undecided. Using clinical and electrophysiological methods, we tried to establish which fibers achieved full postoperative recovery, and the possibility of using non-standard electrophysiological tests as outcome predictors. Methods The study group consisted of 35 patients and controls. The Historical–Objective Scale, standard neurography, conduction velocity distribution tests (CVD), and quantitative sensory testing (QST) were performed before and after CTS surgery. Results Clinical improvement was observed on average in 54.3% of the patients, higher in less advanced CTS. All parameters improved significantly after surgery, except for CVD; most remained worse than in the controls. Only QST parameters fully returned to normal limits. Patient age and CTS severity were important in the estimation of the risk of no improvement. Conclusions The efficiency of minimally invasive CTS surgery is higher in younger patients with less advanced CTS. Complete recovery was present only in small fibers; larger fibers could most likely be responsible for residual signs. We did not notice any benefits in CTS diagnosis using methods of small fiber assessment. QST seemed to be useful in the diagnosis of residual signs, and in deciding upon possible reoperation.

Abstract
The aim of our prospective study was to detect changes in nerve echogenicity of the median nerve before and after successful surgery in patients with carpal tunnel syndrome (CTS) using high-resolution ultrasound. Fifteen patients with a definite diagnosis of CTS who underwent surgery were scanned by one examiner with high-resolution ultrasound, and images were analyzed by two blinded raters using ImageJ to assess the echogenicity of the median nerve (fraction of black) with a semiautomated thresholding technique before and 3 mo after surgery compared with 15 controls. In CTS patients, nerve echogenicity before surgery was significantly lower compared with that of controls (fraction of black: mean 63.9 vs. 44.6, p < 0.0001). Three months after surgery nerve echogenicity significantly increased (fraction of black was lower, mean 55.5; p < 0.0001) as a possible sign of reduction of intraneural edema, but did not reach the values of healthy controls. Semi-automated evaluation of the echogenicity of the median nerve may be used as a marker of successful carpal tunnel release. Further studies are warranted to detect how nerve echogenicity changes after unsuccessful carpal tunnel release.

Abstract
BACKGROUND Patient-reported outcome measures (PROMs) are increasingly used to provide evidence for treatment effects and to guide rehabilitation. To our knowledge, no disease-specific PROM exists for the assessment of patients with flexor tendon lesions of the hand. We believe that PROMs used to assess hand function, regardless of diagnosis, contain relevant items for patients with flexor tendon lesions of the hand. PURPOSE The aim of our study was to identify and collect items from pre-existing PROMs used by clinical experts to assess the health status and function in patients with reduced hand function. STUDY DESIGN A scoping review searching for PROMs with hand-specific content was conducted to ensure face validity. As these items are assumed to have been through an evaluation process by the clinical specialists, they have the advantage and likelihood of being useful. METHODS We searched five bibliographic databases. All PROMs with hand-specific content used to assess hand function were considered for inclusion. Questionnaires written in English, Danish, Swedish, and Norwegian were included. An analysis of content redundancy was conducted, and items were grouped according to The World Health Organization's International Classification of Functioning, Disability and Health. RESULTS Seventy-three PROMs were included with a total of 1,582 items. The majority of the items were redundant across measurement instruments, and redundant items were consolidated, resulting in 179 nonredundant items. All nonredundant items were classified according to the International Classification of Functioning, Disability and Health components. CONCLUSIONS This review presents a collection of 179 items ensuring face validity for patients with hand-related disease/injury.

Objective To investigate changes in the median nerve, retinaculum, and carpal tunnel on ultrasound after successful endoscopic carpal tunnel release (ECTR).

An in-house developed scoring system (0–3) was used to gauge the clinical improvement after ECTR. Ultrasound was performed before ECTR, and at 1, 3, and 12 months post-ECTR. Changes in the median nerve, flexor retinaculum, and carpal tunnel morphology on ultrasound after ECTR were analyzed. Ultrasound parameters for different clinical improvement groups were compared. Results All patients improved clinically after ECTR. The average clinical improvement score ± SD at 12 months post-ECTR was 2.2 ± 0.7. The median nerve cross-sectional area proximal and distal to the tunnel decreased at all time intervals post-ECTR but remained swollen compared to normal values. Serial changes in the median nerve caliber and retinacular bowing after ECTR were more pronounced at the tunnel outlet than at the tunnel inlet. The flexor retinaculum had reformed in 25 (68%) of 37 wrists after 12 months. Conclusion Postoperative changes in median nerve and retinaculum parameters were most pronounced at the tunnel outlet. Even in patients with clinical improvement after ECTR, nearly all ultrasound parameters remain abnormal at one year post-ECTR. These ultrasound parameters should not necessarily be relied upon to diagnose persistent CTS after ECTR.

Abstract
Nerve hydrodissection (HD), a technique used when treating nerve entrapments, involves the injection of an anesthetic, saline, or 5% dextrose in water to separate the nerve from the surrounding tissue, fascia, or adjacent structures. Animal models suggest the potential for minimal compression to initiate and perpetuate neuropathic pain. Mechanical benefits of HD may relate to release of nervi nervorum or vasa nervorum compression. Pathologic nerves can be identified by examination or ultrasound visualization. The in-plane technique is the predominant and safest method for nerve HD. Five percent dextrose may be favored as the preferred injectate based on preliminary comparative-injectate literature, but additional research is critical. Literature-based hypotheses for a direct ameliorative effect of dextrose HD on neuropathic pain are presented.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2020; 39:693-702. [PMID: 31659789 DOI: 10.1002/jum.15146] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Accepted: 09/18/2019] [Indexed: 05/08/2023]
Abstract
OBJECTIVE To document changes in the median nerve cross-sectional area (CSA) in the proximal carpal tunnel region after ultrasound (US)-guided carpal tunnel release (CTR). METHODS Prospective data were collected on 23 consecutive patients (37 wrists) treated with US-guided CTR by the primary author using the same office-based microinvasive technique. Ultrasound was used to measure the largest CSA of the median nerve in the proximal carpal tunnel region both preoperatively and postoperatively. The primary outcome measure was the change in the preoperative versus 6- to 10-week postoperative median nerve CSA. RESULTS The mean CSA of the median nerve decreased from 16.08 to 12.75 mm2 at 6 to 10 weeks after US-guided CTR (P < .001). During the same period, the mean Boston Carpal Tunnel Questionnaire (BCTQ) symptom score decreased from 3.23 to 1.67 (P < .001), and mean BCTQ functional score decreased from 2.49 to 1.47 (P < .001), both exceeding minimal clinically important differences. Although the primary end point was the median nerve CSA at 6 to 10 weeks, statistically significant reductions in the median nerve CSA, as well as BCTQ scores, were also observed as early as 2 to 4 weeks after US-guided CTR (median nerve CSA, 12.40 mm2 ; BCTQ symptom score, 2.00; BCTQ functional score, 1.75; all P ≤ .03). CONCLUSIONS To our knowledge, this investigation was the largest to date examining changes in the proximal median nerve CSA after US-guided CTR. Statistically significant reductions in the proximal median nerve CSA were observed within 6 to 10 weeks after ultrasound-guided CTR. These reductions were similar to those previously reported for open and endoscopic CTR and validate the ability of US-guided CTR to relieve median nerve compression.

JOURNAL OF HAND SURGERY GLOBAL ONLINE 2019; 2:80-83. [PMID: 35415483 PMCID: PMC8991522 DOI: 10.1016/j.jhsg.2019.09.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2019] [Accepted: 09/18/2019] [Indexed: 11/23/2022] Open
Abstract
Purpose The purpose of this study was to determine whether there is a difference in the change in cross-sectional area (CSA) of the median nerve in patients undergoing carpal tunnel release (CTR) based on surgical technique and whether this change is associated with changes in patient-reported outcomes evaluated using the Carpal Tunnel Syndrome Assessment Questionnaire. Methods Individuals with carpal tunnel syndrome were evaluated with ultrasound and the CTSAQ before and 6 weeks after surgery. Patients were eligible for inclusion if they underwent either a mini-open CTR (MOCTR) or endoscopic CTR (ECTR). A single surgeon performed all surgeries. Changes in median nerve CSA, Carpal Tunnel Syndrome Assessment Questionnaire scores, and their associated surgical technique (MOCTR vs ECTR) were analyzed. Results A total of 77 patients were enrolled, 13 of whom were lost to follow-up, which left 64 for analysis. Of those, 42 patients underwent ECTR and 22 MOCTR. Mean age was 55 years; there were 52 women and 12 men. Mean changes in CSA for endoscopic and mini-open techniques from before to 6 weeks after surgery were –1.9 mm2 (95% confidence interval [CI], –1.1 to –2.7) and +0.6 mm2 (95% CI, –1.6 to 0.4), respectively. Mean Symptom Severity Scores improved after endoscopic and mini-open release by 1.7 (95% CI, 1.4–2.1) and 1.5 (95% CI, 1.2–1.9), respectively. Mean Functional Status Scores improved after endoscopic and mini-open release by 1.2 (95% CI, 0.9–1.9) and 0.7 (95% CI, 0.03–1.3), respectively. Conclusions Patients undergoing ECTR demonstrated decreased median nerve CSA, whereas those undergoing MOCTR demonstrated increased median nerve CSA at 6 weeks. All patients undergoing surgical intervention demonstrated improvement in both Symptom Severity Scores and Functional Status Scores after surgery. Whereas both techniques successfully improve patient outcome scores, an increase in CSA after MOCTR may be seen in the initial postoperative period, potentially contributing to a slower short-term improvement in outcome in functional scores compared with ECTR. Type of study/level of evidence Therapeutic IV.
