Management of de Quervain Tenosynovitis: A Systematic Review and Network Meta-Analysis

Importance

There is a plethora of treatment options for patients with de Quervain tenosynovitis (DQT), but there are limited data on their effectiveness and no definitive management guidelines.

Objective

To assess and compare the effectiveness associated with available treatment options for DQT to guide musculoskeletal practitioners and inform guidelines.

Data Sources

Medline, Embase, PubMed, Cochrane Central, Scopus, OpenGrey.eu, and WorldCat.org were searched for published studies, and the World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, The European Union Clinical Trials Register, and the ISRCTN registry were searched for unpublished and ongoing studies from inception to August 2022.

Study Selection

All randomized clinical trials assessing the effectiveness of any intervention for the management of DQT.

Data Extraction and Synthesis

This study was prospectively registered on PROSPERO and conducted and reported per Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-analyses of Health Care Interventions (PRISMA-NMA) and PRISMA in Exercise, Rehabilitation, Sport Medicine and Sports Science (PERSIST) guidance. The Cochrane Risk of Bias tool and the Grading of Recommendations, Assessment, Development, and Evaluations tool were used for risk of bias and certainty of evidence assessment for each outcome.

Main Outcomes and Measures

Pairwise and network meta-analyses were performed for patient-reported pain using a visual analogue scale (VAS) and for function using the quick disabilities of the arm, shoulder, and hand (Q-DASH) scale. Mean differences (MD) with their 95% CIs were calculated for the pairwise meta-analyses.

Results

A total of 30 studies with 1663 patients (mean [SD] age, 46 [7] years; 80% female) were included, of which 19 studies were included in quantitative analyses. From the pairwise meta-analyses, based on evidence of moderate certainty, adding thumb spica immobilization for 3 to 4 weeks to a corticosteroid injection (CSI) was associated with statistically but not clinically significant functional benefits in the short-term (MD, 10.5 [95% CI, 6.8-14.1] points) and mid-term (MD, 9.4 [95% CI, 7.0-11.9] points). In the network meta-analysis, interventions that included ultrasonography-guided CSI ranked at the top for pain. CSI with thumb spica immobilization had the highest probability of being the most effective intervention for short- and mid-term function.

Conclusions and Relevance

This network meta-analysis found that adding a short period of thumb spica immobilization to CSI was associated with statistically but not clinically significant short- and mid-term benefits. These findings suggest that administration of CSI followed by 3 to 4 weeks immobilization should be considered as a first-line treatment for patients with DQT.

Isometric thumb extension exercise as part of a multimodal intervention for de Quervain's syndrome: A randomised feasibility trial

Introduction

de Quervain's syndrome is a painful condition commonly presented to hand therapists. Exercise is utilised as an intervention, but isometric exercise has not been investigated. We aimed to assess the feasibility and safety of isometric thumb extension exercise for de Quervain's syndrome and to explore differences between high-load and low-load isometric exercise.

Methods

This parallel-group randomised clinical feasibility trial included individuals with de Quervain's syndrome. All participants underwent a 2 week washout period where they received an orthosis, education, and range of motion exercises. Eligible participants were then randomised to receive high or low-load isometric thumb extension exercises, performed daily for 4 weeks. Feasibility and safety were assessed by recruitment and drop-out rates, adherence, adverse events, and participant feedback via semi-structured interviews. Secondary outcomes included patient-reported outcomes for pain and function, and blinded assessment of range of motion and strength.

Results

Twenty-eight participants were randomised. There were no drop-outs after randomisation, and no serious adverse events. Adherence to exercise was 86.7%, with 84% of participants stating they would choose to participate again. There were clinically and statistically significant improvements in pain and function over time (p < 0.001) but not in range of motion or strength. There were no statistically significant between-group differences.

Conclusions

Isometric thumb extension exercise within a multimodal approach appears a safe and feasible intervention for people with de Quervain's syndrome. A large multi-centre trial would be required to compare high- and low-load isometric exercises. Further research investigating exercise and multimodal interventions in this population is warranted.

Acupuncture for de Quervain's tenosynovitis: A randomized controlled trial

BACKGROUND

Acupuncture has been an alternative approach for de Quervain's tenosynovitis (DQt), but trial evidence is still lacking.

PURPOSE

This study aimed to assess the efficacy of acupuncture in patients with DQt.

STUDY DESIGN

A randomized controlled trial.

METHODS

A total of 68 subjects with DQt were recruited from outpatients of Department of Orthopaedics and Traumatology, and Chinese medicine clinics, The University of Hong Kong, and were randomized into the acupuncture group (n = 34) and the waitlist group (n = 34). Subjects in the acupuncture group received 5 acupuncture sessions over 2 weeks, followed by a 10-week follow-up. The waitlist control group received assessments only in the first 6 weeks of the waiting period and received the same acupuncture treatment and follow-up as the treatment group in the next 12 weeks. The primary outcome was the general pain intensity using the Visual Analogue Scale (VAS) at the end of treatment (week 2). Secondary outcomes were grip and pinch strengths of affected hands, the quick Disabilities of the Arm, Shoulder and Hand Score (Q-DASH), and the World Health Organization Quality of Life-brief Questionnaire (WHOQOL-BREF) at weeks 2 and 6.

RESULTS

From baseline to 2 weeks, the mean VAS score decreased by 19.5 points in the acupuncture group and by 3.4 points in the waitlist group. The difference for acupuncture vs waitlist control was -16.2 points (95% CI, -26.7 to -5.6, p = 0.003). Acupuncture effects sustained for 10 weeks (mean difference compared with baseline, -30.6; 95% CI, -39.6 to -21.7). Secondary outcomes showed that acupuncture reduced pain intensity, improved grip and pinch strength of affected hands, and Q-DASH scores, but not the scores of WHOQOL-BREF in patients. No serious adverse event occurred during the study period.

CONCLUSIONS

Our findings support that 2-week of acupuncture is safe and effective in the reduction of pain intensity, and improvement of strengths and disabilities of hand in DQt patients. Acupuncture also has long-term effects on DQt.

Common Hand Conditions: A Review

Importance

Carpal tunnel syndrome, trigger finger, de Quervain tenosynovitis, and basilar (carpometacarpal) joint arthritis of the thumb can be associated with significant disability.

Observations

Carpal tunnel syndrome is characterized by numbness and tingling in the thumb and the index, middle, and radial ring fingers and by weakness of thumb opposition when severe. It is more common in women and people who are obese, have diabetes, and work in occupations involving use of keyboards, computer mouse, heavy machinery, or vibrating manual tools. The Durkan physical examination maneuver, consisting of firm digital pressure across the carpal tunnel to reproduce symptoms, is 64% sensitive and 83% specific for carpal tunnel syndrome. People with suspected proximal compression or other compressive neuropathies should undergo electrodiagnostic testing, which is approximately more than 80% sensitive and 95% specific for carpal tunnel syndrome. Splinting or steroid injection may temporarily relieve symptoms. Patients who do not respond to conservative therapies may undergo open or endoscopic carpal tunnel release for definitive treatment. Trigger finger, which involves abnormal resistance to smooth flexion and extension ("triggering") of the affected finger, affects up to 20% of adults with diabetes and approximately 2% of the general population. Steroid injection is the first-line therapy but is less efficacious in people with insulin-dependent diabetes. People with diabetes and those with recurrent symptoms may benefit from early surgical release. de Quervain tenosynovitis, consisting of swelling of the extensor tendons at the wrist, is more common in women than in men. People with frequent mobile phone use are at increased risk. The median age of onset is 40 to 59 years. Steroid injections relieve symptoms in approximately 72% of patients, particularly when combined with immobilization. People with recurrent symptoms may be considered for surgical release of the first dorsal extensor compartment. Thumb carpometacarpal joint arthritis affects approximately 33% of postmenopausal women, according to radiographic evidence of carpometacarpal arthritis. Approximately 20% of patients require treatment for pain and disability. Nonsurgical interventions (immobilization, steroid injection, and pain medication) relieve pain but do not alter disease progression. Surgery may be appropriate for patients unresponsive to conservative treatments.

Conclusions and Relevance

Carpal tunnel syndrome, trigger finger, de Quervain tenosynovitis, and thumb carpometacarpal joint arthritis can be associated with significant disability. First-line treatment for each condition consists of steroid injection, immobilization, or both. For patients who do not respond to noninvasive therapy or for progressive disease despite conservative therapy, surgical treatment is safe and effective.

Surgical Treatment Outcome of de Quervain’s Disease: A Systematic Review and Meta-analysis

Background:

Surgical release of the extensor retinaculum is performed as a treatment for de Quervain’s (DQ) disease when conservative treatment fails. In the literature, there is no consensus about the effectiveness of a surgical release in patients with DQ, the complication rate, or which type of incision is superior. Therefore, a systematic review and meta-analysis were conducted.

Methods:

A systematic search was performed in Embase, Medline Ovid, Web of Science Core Collection, Cochrane, and Google Scholar. Articles regarding surgical treatment of DQ disease that reported outcome and complications were included. We extracted exact values of visual analog scale scores and percentages of patients who experienced pain at follow-up. Complications assessed were (sub) luxation, superficial radial nerve injuries, wound infections, and scar problems.

Results:

Twenty-one studies with a total of 939 patients were included. Five percent of these patients (95% CI 1%–18%) did not show complete remission of pain at follow-up. When pooled, the mean reduction in visual analog scale scores was 5.7 (95% CI 5.3–6.1) on a 0–10 scale. No difference in outcome between different types of surgery or incisions was seen. Based on the meta-analysis, the pooled complication rate was 11% (95% CI 5%–22%).

Conclusions:

Five percent of patients still have residual pain after surgical release of the first extensor compartment. Surgery type, as well as the type of incision, did not affect outcome or complication. Thus, surgical release of the extensor retinaculum for DQ disease is an effective treatment, regardless of the type of surgery.

Effectiveness of surgical interventions for treating de Quervain's disease: A systematic review and meta-analysis

Introduction

This systematic review of randomized controlled trials was undertaken to assess whether any of the various currently used surgical interventions have better functional outcomes and less impairment or fewer surgical complications compared to the other common surgical interventions in de Quervain's disease.

Material and methods

Relevant studies related to surgical interventions in de Quervain's disease based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines were identified from PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials for randomized controlled trials comparing surgical interventions in de Quervain's disease published from January 2000 to December 2020. Functional outcome and impairment were the primary outcomes assessed.

Results

Three trials met the eligibility criteria which were following randomized controlled trial or quasi-experimental trial enrolling adults ≥18 years of age diagnosed with de Quervain's disease, comparing clinical outcomes between different surgical interventions, and including functional outcomes, impairment, pain and complications data. The Cochrane Risk of Bias Assessment Tool and GRADE approach were used to ascertain methodological quality. Statistical heterogeneity was tested with I-square and chi-square tests. The longitudinal skin incision probably slightly reduced superficial radial nerve injury, vein injury, scar hypertrophy, and total complications compared with the transverse skin incision with relative risk: 0.14, very low certainty by GRADE; 0.10, very low certainty by GRADE; 0.57, very low certainty by GRADE; and 0.23, very low certainty by GRADE, respectively.

Conclusion

Concerning the analysis of functional and pain scores, no significant results were able to be concluded. This study's findings must be considered in the light of quality and sample size limitations, and further high quality prospective randomized controlled clinical trials are needed to draw more firm conclusions.

Management of de Quervain Tenosynovitis: A Critical Analysis Review

»

Most cases of de Quervain tenosynovitis can be managed with nonoperative measures, and the mainstay of treatment is corticosteroid injection (CSI). The use of ultrasound may improve the accuracy of injections and can help to identify and localize injections to separate subcompartments.

»

For patients who are in the third trimester of pregnancy or breastfeeding, there is no contraindication to CSI as studies have shown that it can provide optimal symptomatic relief to the mother without impacting the baby.

»

When nonoperative treatment is unsuccessful, surgical release of the first dorsal compartment (FDC) can provide excellent symptom relief. Open release performed through a longitudinal incision allows for better visualization of the underlying anatomy, resulting in fewer injuries to underlying structures and a lower incidence of hypertrophic scarring compared with a transverse incision.

»

For surgeons who are comfortable performing endoscopic techniques, endoscopic FDC release can result in quicker symptom improvement, superior scar cosmesis, and a lower incidence of radial sensory nerve injury.

»

Studies have shown that FDC release can safely and effectively be performed using the WALANT (wide-awake local anesthesia no tourniquet) technique, which has the potential for cost savings without compromising quality or patient comfort.

Ultrasound Measurements of the First Extensor Compartment: Determining the Transection Limits for Ultra-minimally Invasive Release of De Quervain Tenosynovitis

Background: De Quervain syndrome is the second most common compressive tendinopathy. Although the length of the first extensor compartment (FEC) has been studied previously, there is no documented reported comparison study of short-axis and long-axis sonographic measurements. The thread technique, or Guo Technique, has been applied to carpal tunnel syndrome, trigger finger, and superficial peroneal compressive neuropathy. To perform this procedure, it is critically important to accurately identify the boundaries for transection. Methods: Twenty-one fresh frozen cadaver upper extremities were examined under ultrasound to determine the length of the extensor retinaculum (ER) over the FEC. Using the sonographic landmarks, the ERs were measured in short axis and long axis over their proximal to distal margins and from the distal margins to the distal edges of the radial styloids. These sonographic measurements were then compared with gross anatomical measurements. Results: The short-axis sonographic measurement of the ER on average was 22.53 mm (95% confidence interval [CI] = 20.79-24.05 mm). The long-axis sonographic measurement of the ER on average was 15.65 mm (95% CI = 13.70-17.78 mm). The average length of the ER by gross anatomical dissection was 22.40 mm (95% CI = 21.15-23.51 mm). Conclusions: The short axis is not significantly different from the gross anatomical measurement; however, the long axis is significantly lower than the gross anatomical measurement. The results support the idea that the short axis is more accurate than the long axis.

Are Patient Expectations and Illness Perception Associated with Patient-reported Outcomes from Surgical Decompression in de Quervain's Tenosynovitis?

BACKGROUND

Psychological factors such as depression, pain catastrophizing, kinesiophobia, pain anxiety, and more negative illness perceptions are associated with worse pain and function in patients at the start of treatment for de Quervain's tenosynovitis. Longitudinal studies have found symptoms of depression and pain catastrophizing at baseline were associated with worse pain after treatment. It is important to study patients opting for surgery for their condition because patients should choose surgical treatment based on their values rather than misconceptions. Psychological factors associated with worse patient-reported outcomes from surgery for de Quervain's tenosynovitis should be identified and addressed preoperatively so surgeons can correct any misunderstandings about the condition.

QUESTION/PURPOSE

What preoperative psychosocial factors (depression, anxiety, pain catastrophizing, illness perception, and patient expectations) are associated with pain and function 3 months after surgical treatment of de Quervain's tenosynovitis after controlling for demographic characteristics?

METHODS

This was a prospective cohort study of 164 patients who underwent surgery for de Quervain's tenosynovitis between September 2017 and October 2018 performed by 20 hand surgeons at 18 centers. Our database included 326 patients who underwent surgery for de Quervain's tenosynovitis during the study period. Of these, 62% (201 of 326) completed all baseline questionnaires and 50% (164 of 326) also completed patient-reported outcomes at 3 months postoperatively. We found no difference between those included and those not analyzed in terms of age, sex, duration of symptoms, smoking status, and workload. The mean ± SD age of the patients was 52 ± 14 years, 86% (141 of 164) were women, and the mean duration of symptoms was 13 ± 19 months. Patients completed the Patient-Rated Wrist Evaluation (PRWE), the VAS for pain and function, the Patient Health Questionnaire for symptoms of anxiety and depression, the Pain Catastrophizing Scale, the Credibility/Expectations Questionnaire, and the Brief Illness Perceptions questionnaire at baseline. Patients also completed the PRWE and VAS for pain and function at 3 months postoperatively. We used a hierarchical multivariable linear regression model to investigate the relative contribution of patient demographics and psychosocial factors to the pain and functional outcome at 3 months postoperatively.

RESULTS

After adjusting for demographic characteristics, psychosocial factors, and baseline PRWE score, we found that only the patient's expectations of treatment and how long their illness would last were associated with the total PRWE score at 3 months postoperatively. More positive patient expectations of treatment were associated with better patient-reported pain and function at 3 months postoperatively (ß = -2.0; p < 0.01), while more negative patient perceptions of how long their condition would last were associated with worse patient-reported pain and function (timeline ß = 2.7; p < 0.01). The final model accounted for 31% of the variance in the patient-reported outcome at 3 months postoperatively.

CONCLUSION

Patient expectations and illness perceptions are associated with patient-reported pain and functional outcomes after surgical decompression for de Quervain's tenosynovitis. Addressing misconceptions about de Quervain's tenosynovitis in terms of the consequences for patients and how long their symptoms will last should allow patients to make informed decisions about the treatment that best matches their values. Prospective studies are needed to investigate whether addressing patient expectations and illness perceptions, with decision aids for example, can improve patient-reported pain and function postoperatively in those patients who still choose surgery for de Quervain's tenosynovitis.

An Evidence-Based Review of Overuse Wrist Injuries in Athletes

Overuse wrist injuries are a common problem in athletes and can be related to tendinopathies or osteoarticular pathology. Fortunately, athletes rarely miss time from their sport due to these conditions because many can be treated nonoperatively. For refractory cases, there often is a curative surgical procedure that can be done during the off-season.

Ultrasound-Guided de Quervain's Tendon Release, Feasibility, and First Outcomes

Background  de Quervain's syndrome is one of the main tendonitis of the wrist. The hypothesis of authors was that de Quervain's syndrome could be successfully treated with a specific ultrasound-guided percutaneous procedure, as it is for trigger finger. Surgical Technique  Identification of the subcompartmentalization of the first extensor compartment was performed first, using the Hiranuma's classification, prior to the surgery. Then, we assessed precisely the positions of the sensory branches of the radial nerve and drew the landmarks. Through a continuous ultrasound in-plane control, we performed a percutaneous retrograde section of each part of the first compartment of the extensors, using a dedicated surgical blade. Methods  In a cadaveric study, authors proposed to assess the feasibility and safety of a new and specific procedure and then assessed their first clinical cases. Fourteen specimen wrists were analyzed with ultrasound and the procedure was performed prior to an open control of the efficiency of the release, and safety for the superficial nerves. Then, we reported the results of the 22 first patients included in the clinical series. Results  In a cadaver laboratory, authors were able to identify with ultrasound the type of first compartment septation (subcompartmentalization) in 13 cases ( n  = 14). The misidentification induced one incomplete release. No damages of the superficial radial nerve were observed despite close relationship. In the small series ( n  = 22), the duration of surgery was 8 minutes (range: 4-18 minutes). It was performed in office surgery and no morbidities were noticed. All patients improved, from quickDASH preoperative score of 59 (range: 28-71) to quichDASH postoperative score of 9 (range: 0-25). Conclusion  Ultrasound-guided percutaneous release in the de Quervain's disease is a safe and reliable procedure without specific morbidity. Great care should be taken to avoid sensory nerve injuries and to identify the correct type of subcompartmentalization with a precise ultrasound evaluation.

Which Psychological Variables Are Associated With Pain and Function Before Surgery for de Quervain's Tenosynovitis? A Cross-sectional Study

BACKGROUND

Depression, anxiety, and pain catastrophizing have been associated with worse pain and function in studies of patients with de Quervain's tenosynovitis. Illness perceptions are the patient's thoughts and feelings about their illness. More negative perceptions of the illness such as the illness having a long duration or serious consequences are associated with worse physical function in patients with hand osteoarthritis. It is currently unknown whether these psychological factors play a similar role in de Quervain's. We chose to study patients who have tried nonoperative management and have chosen surgical decompression due to persistent symptoms. Psychological factors may be associated with their ongoing pain and impaired function, so it is particularly important to investigate the role of psychosocial factors that may be targeted with non-invasive interventions.

QUESTIONS/PURPOSES

Which psychological variables are independently associated with baseline pain and function in patients undergoing surgical treatment for de Quervain's tenosynovitis, after controlling for clinical and demographic variables?

METHODS

This cross-sectional study included data from a longitudinally maintained database on 229 patients who had surgery for de Quervain's tenosynovitis between September 2017 and October 2018. All management options were discussed with patients, but many had already tried nonoperative management and chose surgery once referred to our institution. Our database included 958 patients with de Quervain's, with 69% (659) managed nonoperatively and 34% (326 of 958) who underwent surgical decompression. A total of 70% (229 of 958) completed all questionnaires and could be included in the study. With the numbers available, we found no differences between those included and those not analyzed in terms of age, gender, duration of symptoms, BMI, smoking status, and workload.Patients completed the Patient-Rated Wrist/Hand Evaluation (PRWHE), Patient Health Questionnaire for emotional distress, Pain Catastrophizing Scale (PCS), and the Brief Illness Perception Questionnaire. We investigated the relative contribution of patient demographics and individual psychosocial factors using a hierarchical multivariable linear regression model. In the first step we considered how demographic factors were associated with the baseline PRWHE score. In the second step we investigated the effect of pain catastrophizing and emotional distress on the baseline PRWHE score after accounting for confounding demographic factors. In the final step, the effect of illness perceptions on baseline PRWHE were considered after accounting for the confounding effects of demographic factors as well as pain catastrophizing and emotional distress.

RESULTS

After controlling for confounding variables including workload and emotional distress, a more negative patient perception of the consequences of their condition and worse pain catastrophizing were associated with worse pain and function (consequences, β = 0.31; p < 0.01, pain catastrophizing β = 0.17; p = 0.03). A hierarchical multivariable regression analysis found that 11% of variance in baseline pain and function was explained by pain catastrophizing and emotional distress. Illness perceptions brought the total explained variance of the final model to 34%.

CONCLUSIONS

More negative perceptions of the consequences of de Quervain's tenosynovitis and worse pain catastrophizing are associated with worse pain and reduced function at baseline in patients awaiting surgical decompression of de Quervain's tenosynovitis. In light of these findings, future studies might explore interventions to reduce pain catastrophizing and lower the perceived consequences of the condition. This may reduce the number of patients choosing surgical decompression or may also improve surgical outcomes. Further work should consider if these psychological factors are also associated with postoperative patient-reported outcomes.

Tendoscopic versus open release for de Quervain's disease: earlier recovery with 7.21 year follow-up

Purpose

To compare the time return to work and long-term results of tendoscopic versus open technique for de Quervain’s disease.

Methods

From 2005 to 2013, either tendoscopic or open decompression was performed on 56 consecutive patients (56 wrists) with symptomatic de Quervain’s disease despite a minimum of 3 months non-operative treatment. Of the 50 patients who met the inclusion criteria, 41 patients were followed-up for a mean of 7.21 years postoperatively. Among these 41 wrists, 20 underwent tendoscopic release (group A), and 21 underwent open release (group B). The clinical evaluations were performed preoperatively, 1 month postoperatively and at last follow-up visit, using visual analog scale (VAS); the Disabilities of the Arm, Shoulder and Hand (DASH) Outcome score; and the Finkelstein’s test. The Patient and Observer Scar Assessment Scale (POSAS) was used as an esthetic evaluation tool of the scar at last follow-up.

Results

No significant baseline differences were found between two groups. The average time return to work in group A was less than in group B (P < 0.05), The mean VAS and DASH scores improved significantly in both groups at 1 month and last follow-up visit (P < 0.001). At 1 month, the scores in group A were significantly better than in group B (P < 0.05 and P < 0.001, respectively). There was no difference between groups at last follow-up. In addition, the improvement of the mean DASH score was significantly greater in group A than in group B (34.74 ± 10.99 in group A and 23.58 ± 12.01 in group B, P < 0.01) at 1 month. For POSAS scale, both the OSAS and PSAS scores were significantly better in group A. One patient in group A had cephalic vein injury and 3 patients in group B was involved with radial sensory nerve injury. All patients showed negative on Finkelstein’s test at last follow-up.

Conclusions

The results of this study suggest that tendoscopic technique for de Quervain’s disease could provide earlier symptom relief and earlier recovery with fewer complications and more desirable scar, as well as equivalent successful long-term outcome, when compared with traditional open release technique.

Tendon Subluxation After Surgical Release of the First Dorsal Compartment in De Quervain Disease

We aimed to determine whether dorsoulnar incision elevating radial flap and immobilization for the treatment of de Quervain disease have an advantage over simple midline incision and early mobilization, respectively, in terms of tendon subluxation and clinical outcomes. Forty-six patients with de Quervain disease were randomly divided into 2 groups (midline incision vs dorsoulnar incision) and 2 subgroups (immobilization vs early mobilization). Subluxation of intracompartmental tendons was measured in dynamic wrist positions at 12 and 24 weeks using ultrasonography. The DASH (Disabilities of the Arm, Shoulder, and Hand) and visual analog scale scores and grip and pinch strengths were evaluated. At 24 weeks, the tendons were displaced voloradially in wrist volar flexion (1.25 mm in midline incision vs 0.36 mm in dorsoulnar incision, P = 0.001), whereas the tendons were displaced dorsoulnarly in wrist extension (0.95 mm in midline incision vs 1.78 mm in dorsoulnar incision, P = 0.041). There were no significant differences in tendon displacement between early mobilization and immobilization groups. Clinical outcome measures showed no variation between the groups, and no significant correlation occurred with tendon subluxation. Dorsoulnar incision and postoperative immobilization do not have advantage over midline incision and early mobilization, respectively. However, tendon subluxation after release of the first dorsal compartment for de Quervain disease does not affect clinical outcomes.

One portal endoscopic release of the first extensor compartment in de Quervain's disease

OBJECTIVES

We aimed to present preliminary result of one portal endoscopic assisted release of first dorsal compartment at wrist in a case series with de Quervain disease as a minimal invasive surgical method.

MATERIALS AND METHODS

The patients, who underwent an endoscopic-assisted release of the first extensor compartment for de Quervain's disease by same hand surgeon between 2015 and 2017, were retrospectively analyzed. Operative treatment was considered if the patients did not respond to non-operative treatment including oral anti-inflammatory medications, splinting, and steroid injection. Surgical release was recommended after minimum four months of unsuccesful non-operative treatment, including a steroid injection. 10 wrists were treated with one portal endoscopic assisted release. All patients were evaluated at an average of 16.1 months follow-up using visual analog scale (VAS) pain ratings and the Disabilities of Arm, Shoulder and Hand (DASH) score.

RESULTS

The mean operating time was 13.9 min (range, 10-21min). The mean VAS and DASH scores were improved from 8.2 to 1.9 and 70.51 to 2.81 respectively. No significant difference was found between operated and non-operated arms in postoperative pinch and strengths. Transient superficial radial nerve paresthesia (two wrists) and significant scar tenderness (one) were identified in three cases. There was no patient that complain of unsightly scar and tendon subluxation.

CONCLUSIONS

One portal endoscopic assisted release of the extensor compartment is an effective and safe minimal invasive procedure with similar complication rates reported previously in open and endoscopic procedures in patients with de Quervain's disease who are unresponsive to non-operative treatments.

Tendon Harvest for Treatment of Radial Nerve Palsy Using Endoscopic Technique

BACKGROUND

Endoscopic method for many surgeries with minimal access is proposed to be effective for preventing the excessive scar formation, reducing pain, cosmesis, and the early return to work. Surgical outcomes of endoscopic and open methods for tendon harvest in treatment of radial nerve palsy were evaluated.

METHODS

In a randomized single-blind clinical trial study, 10 patients with radial nerve palsy who referred to the Plastic Surgery Department of the Fatimah Zahra Hospital, Iran University of Medical Sciences, Tehran, Iran were divided into two equal groups. Flexor carpi radialis (FCR), flexor carpi ulnaris (FCU) and the palmaris longus (PL) tendons were harvested by endoscopic or open techniques. The outcomes (tendon harvest time, rate of post-surgical pain, amount of pain medication, patient satisfaction, amount of scar, and length of scar) are measured.

RESULTS

There was no significant difference in time of surgery between two methods. Vancouver scar scale, cosmetic satisfaction, severity of postoperative pain and also drugs for pain relief after tendon harvest surgery were significantly lower in endoscopic method than open method.

CONCLUSION

Regarding the low invasiveness, high satisfaction rate of patients, low pain severity, low scar and the little need for opiate to reduce pain in the endoscopic method, endoscopic tendon harvest technique for radial nerve palsy seems to have priority over open method.

Tenosynovitis of the Hand and Wrist: A Critical Analysis Review

Trigger FingerTrigger finger is common in patients with diabetes.Corticosteroid injections are effective in about 60% to 92% of cases.Proximal interphalangeal joint contracture may occur in long-standing cases.The outcomes of open and percutaneous releases are similar; however, surgeons are split on preferences. Intersection SyndromeThe classic finding is crepitus with wrist motion at the distal one-third of the radial aspect of the forearm. Extensor Pollicis Longus (EPL) TenosynovitisCorticosteroid injections should be used with caution because of the potential for rupture.EPL tenosynovitis is very rare. de Quervain DisorderThis condition is common in postpartum women.A positive Finkelstein test is considered to be pathognomonic of de Quervain disorder, but care should be taken to differentiate this condition from thumb carpometacarpal arthritis.Corticosteroid injections are effective in about 80% of cases.Patients in whom corticosteroid injections fail to provide relief of symptoms frequently have a separate extensor pollicis brevis (EPB) compartment.The abductor pollicis longus (APL) tendon has multiple slips; care should be taken not to confuse one of these slips as the EPB.Traction on the APL pulls up the thumb metacarpal but not the thumb tip.Traction on the EPB extends the thumb metacarpophalangeal joint.Care should be taken to avoid injury to the sensory branch of the radial nerve. Fourth Compartment TenosynovitisThis uncommon condition is most often seen in patients with rheumatoid arthritis.The condition involves a large diffuse area, as opposed to the compact dorsal ganglion cyst.

Hand therapists and researchers have numerous options when selecting outcome measures for patients with wrist pathologies. An evidence-based approach to determining which measures are used most often can inform choices.

PURPOSE OF THE STUDY

To describe how frequently outcome measures are used in recent randomized controlled trials of patients with wrist diagnoses. Identifying assessment design and related International Classification of Functioning, Disability and Health (ICF) domains provides additional consideration for selection.

METHODS

Systematic PubMed and Cumulative Index to Nursing and Allied Health Literature searches for the time frame between January 2005 and March 2015 captured measures used in randomized controlled trials researching wrist-specific fractures, ligament injuries, nerve injuries, arthritis/arthroplasty, or stress injuries/wrist pain.

RESULTS

Three most frequent measures used within each diagnostic category are detailed with assessment design described and ICF domain identified. Across diagnoses, grip/pinch strength and Disabilities of Arm, Shoulder and Hand were the most frequently used physical and patient-reported outcome measures, respectively. The Jebsen-Taylor Hand Function Test was the most frequently used performance measure.

DISCUSSION AND CONCLUSIONS

Consideration of the evidence, ICF domains, wrist diagnoses, and assessment design can help hand therapists select the measure most appropriate for use.

Consensus on a multidisciplinary treatment guideline for de Quervain disease: results from the European HANDGUIDE study

BACKGROUND

De Quervain disease is a common pathology resulting in pain caused by resisted gliding of the abductor pollicis longus and extensor pollicis brevis tendons in the fibro-osseous canal. In a situation of wavering assumptions and expanding medical knowledge, a treatment guideline is useful because it can aid in implementation of best practices, the education of health care professionals, and the identification of gaps in existing knowledge.

OBJECTIVE

The aim of this study was to achieve consensus on a multidisciplinary treatment guideline for de Quervain disease.

DESIGN

A Delphi consensus strategy was used.

METHODS

A European Delphi consensus strategy was initiated. A systematic review reporting on the effectiveness of surgical and nonsurgical interventions was conducted and published and was used as an evidence-based starting point for this study. In total, 35 experts (hand therapists and hand surgeons selected by the national member associations of their European federations and physical medicine and rehabilitation physicians) participated in the Delphi consensus strategy. Each Delphi round consisted of a questionnaire, an analysis, and a feedback report.

RESULTS

Consensus was achieved on the description, symptoms, and diagnosis of de Quervain disease. The experts agreed that patients with this disorder should always receive instructions and that these instructions should be combined with another form of treatment and should not be used as a sole treatment. Instructions combined with nonsteroidal anti-inflammatory drugs (NSAIDs), splinting, NSAIDs plus splinting, corticosteroid injection, corticosteroid injections plus splinting, or surgery were considered suitable treatment options. Details on the use of instructions, NSAIDs, splinting, corticosteroid injections, and surgery were described. Main factors for selecting one of these treatment options (ie, severity and duration of the disorder, previous treatments given) were identified. A relationship between the severity and duration of the disorder and the choice of therapy was indicated by the experts and reported in the guideline.

LIMITATIONS

One of the limitations of a Delphi method is its inability to forecast future developments. It investigated current opinions of the treatment of people with de Quervain disease.

CONCLUSIONS

This multidisciplinary treatment guideline may help in the treatment of and research on de Quervain disease.

Small longitudinal S incision and page turning style of annular ligament partial resection to treat stenosing tenosynovitis of thumb flexor tendon

Background

To present the treatment outcome for patients with stenosing tenosynovitis of thumb flexor tendon treated with a small S incision and page turning style of annular ligament partial resection.

Material/Methods

During a 2-year period between August 2011 and July 2013, 12 consecutive patients (mean age, 45.8 years) with stenosing tenosynovitis of the thumb flexor tendon were prospectively enrolled into this study. All 12 patients underwent longitudinal S skin incision to expose annular ligament and thumb flexor tendon, and with page turning style of annular ligament partial resection to finish the operation. The average range of motion of metacarpophalangeal thumb joint, Quick disability of arm, shoulder, and hand and Short Musculoskeletal Function Assessment Dysfunction score of arm and hand were primary outcome measures.

Results

There were 9 cases of stiff metacarpophalangeal joint of thumb and 3 cases of snapping thumb for stenosing tenosynovitis. At 1-year follow-up, all stenosing tenosynovitis had healed by an average of 4 weeks. The average range of motion of the metacarpophalangeal joint was 37.1° (range, 34–40°). No patients had recurrence, cicatricial contraction, or postoperative infection. The average disability of arm, shoulder, and hand was 0.3 out of 100 (range, 0–1.67), and average Short Musculoskeletal Functional Assessment Dysfunction score of arm and hand was 6.9 out of 40 (range, 0–15.6). All 12 patients stated that they were highly satisfied.

Conclusions

Small S incision and page turning style of annular ligament partial resection for stenosing tenosynovitis of thumb flexor tendon is a safe, simple, and reliable alternative treatment with minimal soft-tissue irritation, good functional results and recovery can be expected.

The relationship of the superficial radial nerve and its branch to the thumb to the first extensor compartment

PURPOSE

The superficial radial nerve and its branches are vulnerable during surgery for de Quervain tenovaginitis. We studied the proximity of the nerve branches to the first extensor compartment.

METHODS

We dissected 20 forearms of 11 cadavers and measured the branching point of the superficial radial nerve relative to the radial styloid. We defined the midline of the first extensor compartment and measured distances of nerves adjacent to it.

RESULTS

The superficial radial nerve gave the lateral dorsal digital branch to the thumb at 50 ± 13 mm (minimum, 26 mm; maximum, 72 mm) proximal to the radial styloid. Average distances of the lateral dorsal digital branch to the thumb to the midline of first extensor compartment from proximal to distal were 2, 2, and 2 mm, respectively. In 8 forearms, the lateral dorsal digital branch to the thumb passed directly over the first extensor compartment along its entire length. We found that as the superficial radial nerve diverged from the first extensor compartment, its lateral dorsal digital branch to the thumb coursed parallel and in close relation to it.

CONCLUSIONS

Anatomic knowledge of the course of the superficial radial nerve and its branches is important during open release for avoiding nerve injury.

CLINICAL RELEVANCE

The close relation of the superficial radial nerve and its lateral dorsal digital branch to the thumb with the first extensor compartment may guide surgeons during surgery for de Quervain tenovaginitis.
