Testosterone Replacement Therapy and Associated Rates of Trigger Finger, de Quervain Tenosynovitis, and Their Subsequent Management.

PURPOSE: Anabolic steroid therapy has been associated with tendon injury, but there is a paucity of evidence associating physiologic testosterone replacement therapy (TRT) with tenosynovitis of the hand, specifically trigger finger and de Quervain tenosynovitis. The purpose of this study was to evaluate the relationship between TRT and tenosynovitis of the hand. METHODS: This was a one-to-one exact matched retrospective cohort study using a large nationwide claims database. Records were queried between 2010 and 2019 for adult patients who filled a prescription for TRT for 3 consecutive months. Rates of new onset trigger finger and de Quervain tenosynovitis and subsequent steroid injection or surgery were identified using ICD-9, ICD-10, and Current Procedural Terminology billing codes. Single-variable chi-square analyses and multivariable logistic regression were used to compare rates in the TRT and control cohorts while controlling for potential confounding variables. Both unadjusted and adjusted odds ratios (OR) are reported for each comparison. RESULTS: In the adjusted analysis, patients undergoing TRT were more than twice as likely to develop trigger finger compared to their matched controls. TRT was also associated with an increased likelihood of experiencing de Quervain tenosynovitis. Of the patients diagnosed with either trigger finger or de Quervain tenosynovitis over the 2-year period, patients with prior TRT were roughly twice as likely to undergo steroid injections or surgical release for both trigger finger and de Quervain tenosynovitis compared to the controls. CONCLUSIONS: TRT is associated with an increased likelihood of both trigger finger and de Quervain tenosynovitis, and an increased likelihood of requiring surgical release for both conditions. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Corticosteroid injection versus immobilisation for the treatment of De Quervain's tenosynovitis: A systematic review and meta-analysis.

OBJECTIVE: De Quervain's tenosynovitis causes pain and impairment of thumb function. Conservative treatments comprise corticosteroid injection and immobilization, and it is unclear which offers greater efficacy. Previous reviews were limited by the small number of included studies; thus an updated review and meta-analysis is warranted. METHODS: A systematic review of the PubMed, Embase, and Web of Science databases was conducted. Randomized control trials comparing corticosteroid injection to immobilization were included. Two authors screened articles, extracted data, and assessed the risk of bias of included studies. Meta-analyses using the random-effects model were conducted, calculating pooled relative risks and mean differences with 95% confidence intervals. RESULTS: 16 studies comprising 1206 patients were included. Corticosteroid injection showed greater treatment success than immobilization (relative risk: 1.61; 95% confidence interval: 1.21-2.15). Combining treatments demonstrated greater efficacy than immobilization (relative risk: 2.15; 95% confidence interval: 1.77-2.62) or injection alone (relative risk: 1.23; 95% confidence interval: 1.12-1.34). Pain and disability scores were lower with injection than immobilization and with combined treatment than with either alone. CONCLUSION: Corticosteroid injection is more effective than immobilization for De Quervain's tenosynovitis, and combining the two treatments provides additional benefit. We recommend corticosteroid injection in first line treatment and immobilization as adjuvant therapy. Further research is required regarding optimal corticosteroid and local anesthetic formulations.

Effectiveness of high-intensity laser application combined with splinting and therapeutic exercise in subacute de Quervain's tenosynovitis: A pilot study.

The purpose of this study is to determine the additional effect of high-intensity laser therapy (HILT) when combined with therapeutic exercise and splinting in the treatment of patients diagnosed with de Quervain's tenosynovitis. Nineteen patients diagnosed with de Quervain's tenosynovitis were randomly divided into two groups: the HILT group and the sham HILT group. A total of 9 HILT or sham HILT sessions were administered, with 3 sessions per week for 3 consecutive weeks. Both groups received the thumb spica splint and therapeutic exercise. A comparison was conducted between the two groups, as well as pre- and post-treatment, focusing on the following outcomes: Visual Analog Scale (VAS) for pain, hand grip strength, and Thai version of Patient-Rated Wrist and Hand Evaluation (PRWHE-Thai) as a disability score. No significant differences were found between the HILT group and the sham group across all evaluated outcomes. However, when examining changes within each group over time, both the HILT and sham groups showed significant reductions in pain and improvements in disability score at the follow-up assessments compared to baseline. On the other hand, no statistically significant differences were observed in grip strength outcomes at any of the measured time points. The combination of HILT with a splint and exercise demonstrates effectiveness as a method for pain management and functional improvement in patients with subacute de Quervain's tenosynovitis. It is important to note that HILT does not offer any additional advantages when compared to the combined use of a splint and exercise.

Association of Patient-Reported Outcomes Measurement Information System Measures With Injection and Surgical Treatment Response in Patients With De Quervain Tenosynovitis.

PURPOSE: Treatment of de Quervain tenosynovitis is largely empiric. Patient-Reported Outcomes Management Information System (PROMIS) scores at the time of diagnosis might provide insights into the probability of success of nonsurgical management and predict the necessity for surgical treatment. We aimed to identify which, if any, of the PROMIS metrics may be used to identify patients who will opt for surgery or be managed with injection alone. METHODS: Patients presenting to a tertiary academic medical center from 2014 to 2019, with a sole diagnosis of de Quervain tenosynovitis, were identified and separated by initial and most invasive treatment of either injection or surgery. These groups were then dichotomized using cut points of more than one SD from the mean on the PROMIS physical function and pain interference scales, and a logistic regression model was used to determine the odds ratio of surgical intervention. RESULTS: Patients who had low physical function or high pain interference had significantly increased odds of ultimately undergoing surgery. Age ranging from 40 to 60 years and female sex were also associated with increased odds of undergoing surgery. CONCLUSIONS: Patients who scored lower than 40 for physical function or higher than 60 for pain interference had significantly increased odds of eventually undergoing surgical release for de Quervain tenosynovitis. PROMIS scores may identify patients who are likely to fail steroid injections as a sole nonsurgical intervention and inform an individualized discussion about surgical management of this condition. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Unblinding de Quervain: A systematic review of ultrasound-guided injection of corticosteroids for treatment of stenosing tenosynovitis of the 1st extensor compartment.

A systematic review was conducted on studies reporting steroid injections with ultrasound for de Quervain. From 10 studies included and 379 wrists, 73.9% reported complete resolution of symptoms, 18.2% with partial and 7.9% without resolution. When compared to the landmark-guided technique, ultrasound guidance showed significantly higher rates of symptom resolution (P = 0.0132) and lower pain scores (P < 0.0001). Twenty-nine patients out of 163 who initially showed complete resolution of symptoms reported subsequent recurrence. We conclude that steroid injections guided by ultrasound present high rates of symptomatic relief through precise needle insertion, especially in cases of anatomic variability with subcompartments.

De Quervain's tenosynovitis: a non-randomized two-armed study comparing ultrasound-guided steroid injection with surgical release.

PURPOSE: Ultrasonography is currently used for both diagnostic and therapeutic purposes in de Quervain's tenosynovitis. There is a dearth of information on how effective an ultrasound-guided (USG) steroid injection is when compared to surgical release of the first extensor compartment. Hence, we performed a non-randomized two-armed comparison study to test our hypothesis that USG guided steroid injection is equally effective as surgery. METHOD: 62 consecutive patients participated in the study with 32 of them selecting the option of USG guided injection (Set A), and the rest undergoing surgical release (Set B). We reviewed them after 3 and 6 weeks and 6 months for functional outcome using DASH, PRWE and VAS scores, recurrence, or any complications. They were further followed if they were symptomatic. RESULTS: The DASH/PRWE/VAS scores improved at the end of 6 months from 81.7/79.3/6.8 to 1.0/1.7/1.0, respectively for patients undergoing USG guided steroid injection. Similarly, for the patient undergoing surgery, the scores improved from 82.2/81.5/6.7 to 1.7/3.4/1.0, respectively. This was statistically significant in both the groups (p < 0.05) and was comparable to each other. Two patients in Set A came back with recurrence at eight and 10 months and two reported occasional pain on heavy work. Three patients had tenderness and two had numbness in Set B at the scar site. CONCLUSION: We observed that USG guided steroid injections are comparable to surgical release in terms of pain relief, functional outcome, complications.

Comparison of the effect of ketorolac versus triamcinolone acetonide injections for the treatment of de Quervain's tenosynovitis: a double-blind randomized controlled trial.

BACKGROUND: De Quervain's disease is tenosynovitis of the first dorsal compartment causing severely painful radial-side wrist pain and impaired function. Steroids are effective in treating this condition due to their anti-inflammatory properties. However, this drug causes problems such as hypopigmentation, and is contradicted in diabetes mellitus patients. Non-steroidal anti-inflammatory drug (NSAID) which are efficacious in shoulder pathology and not contraindicated in diabetics and can be used to avoid the local effects of steroids could be beneficial for some patients. The present study was a randomized controlled trial to examine the differences in pain scores and functional response to local injections of a corticosteroid and the NSAID ketorolac. METHODS: Sixty-four patients with radial styloid tenosynovitis were randomized using a computer-generated random number table into two groups receiving either a ketorolac injection or a triamcinolone injection. We evaluated post-injection pain intensity using a verbal numerical rating scale (VNRS), functional outcomes using the Thai Disabilities of the Arm, Shoulder and Hand (DASH) scale, and evaluated grip and pinch strengths, recorded at baseline and 6 weeks after the injection. RESULTS: Thirty-one participants in the ketorolac group and 29 participants in the triamcinolone group completed the study and were included in the analysis. There were no significant differences in the assessments at baseline. At the 6-week conclusion of the study, patients in the triamcinolone group had a statistically lower average pain score than in the ketorolac group (0.7 ± 2.0 vs 5.3 ± 3.2, P < 0.001), higher DASH functional score (4.4 ± 6.5 vs 34.1 ± 20.2, P < 0.001), higher right grip strength (60.8 ± 16.8 vs 49.2 ± 18.6, P < 0.015), and higher left grip strength (59.8 ± 18.1 vs 50.3 ± 18.0, P < 0.04). However, there was no difference in pinch strength. CONCLUSIONS: Our study found that ketorolac injections resulted in inferior pain reduction, functional score and grip improvement than triamcinolone injection in patients with radial styloid tenosynovitis. Future studies are required to examine the effects of ketorolac in larger group and with longer follow-up periods to further elucidate the findings of this study. TRIAL REGISTRATION: The study was registered at Clinicaltrials.in.th (TCTR20200909006).

Effectiveness of Corticosteroid Injections in Diabetic Patients With De Quervain Tenosynovitis.

PURPOSE: We sought to determine the effectiveness of corticosteroid injections (CSIs) for de Quervain tenosynovitis in patients with diabetes mellitus. METHODS: We retrospectively identified all patients with diabetes receiving a CSI for de Quervain tenosynovitis by 16 surgeons over a 2-year period. Data collected included demographic information, medical comorbidities, number and timing of CSIs, and first dorsal compartment release. Success was defined as not undergoing an additional CSI or surgical intervention. The mixture of a corticosteroid and local anesthetic provided in each injection was at the discretion of each individual surgeon. RESULTS: Corticosteroid injections were given to 169 wrists in 169 patients with diabetes. Out of 169 patients, 83 (49%) had success following the initial CSI, 44 (66%) following a second CSI, and 6 (67%) following a third CSI. A statistically significant difference was identified in the success rates between the first and second CSIs. Ultimately, 36 of 169 wrists (21%) underwent a first dorsal compartment release. CONCLUSIONS: Patients with diabetes mellitus have a decreased probability of success following a single CSI for de Quervain tenosynovitis in comparison to nondiabetic patients, as described in the literature. However, the effectiveness of each additional CSI does not appear to diminish. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Is a Steroid Injection in Both Compartments More Effective than an Injection in the Extensor Pollicis Brevis Subcompartment Alone in Patients with de Quervain Disease? A Randomized, Controlled Trial.

BACKGROUND: Ultrasonography (US)-guided steroid injections can improve the accuracy of injection in patients with de Quervain disease, especially in those with an intracompartmental septum. Although the main lesion of de Quervain disease in patients with a septum is a stenosing tenosynovitis of the extensor pollicis brevis (EPB), no report we know of has compared injection into the EPB subcompartment with an injection into both the abductor pollicis longus (APL) and EPB subcompartments. In this randomized trial, we compared the results of US-guided steroid injections targeting both subcompartments and the EPB subcompartment alone in patients with de Quervain disease. QUESTIONS/PURPOSES: (1) Do patients who receive a steroid injection in the EPB subcompartment alone have lower pain scores at 6 weeks and at 3 months after US-guided injection compared with patients who receive an injection in both subcompartments? (2) Do patients who receive a steroid injection in the EPB subcompartment alone experience fewer steroid injection-related complications than patients who receive an injection in both subcompartments? METHODS: A randomized controlled study was performed at a single center between August 2018 and March 2021. Patients with a diagnosis of de Quervain disease and with a complete intracompartmental septum between the APL and the EPB tendons were included. In total, 112 patients had a diagnosis of de Quervain disease during the study period. Definite, complete subcompartmentalization was seen in 50 patients. Patients were randomly assigned to US-guided injections targeting both subcompartments (n = 25) or the EPB subcompartment alone (n = 25). There were no between-group differences in age, gender, affected wrist, or disease duration, and all patients had US evidence of tendinosis of the EPB, with or without tendinosis of the APL. Although 33% of patients (16 of 48) showed tendinosis of the APL, no patient showed tendinosis of the APL alone. In all patients, a dorsal-to-palmar side injection of 0.5 mL of 2% lidocaine and 0.5 mL of triamcinolone acetonide (40 mg/mL) was administered by two experienced hand surgeons. In the both-subcompartments group, US-guided injections were performed in each of the APL and EPB subcompartments. In the EPB subcompartment group, US-guided injections were administered in the EPB subcompartment only. All patients underwent the same protocol after the procedure. Four percent (n = 2, 1 in each group) of patients were excluded after randomization because their pain level was not registered. Pre- and postinjection clinical outcome assessments were completed by orthopaedic surgery residents not involved in patient management. Patients were regularly examined at baseline, 6 weeks, and 3 months to evaluate the intensity of pain. We assessed pain by the VAS score, where 0 indicated no pain and 100 the most pain. At baseline, the VAS score was 67 ± 14 in the both-subcompartment group and 67 ± 16 in the EPB subcompartment group (mean difference 0.17 [95% CI -8.45 to 8.82]; p = 0.97). Complications related to the steroid injection, including numbness, tendon rupture, and skin hypopigmentation, were also recorded at final follow-up examinations. To determine statistical power, the VAS score for pain at 6 weeks after the injection was used as the primary outcome variable. The minimum clinically important difference for the VAS score was deemed to be 20 mm, and we estimated an SD of 23. A sample size calculation indicated that a sample of 21 patients per group would provide 80% power to detect an effect of this size between the groups at the p = 0.05 level using a t-test. RESULTS: There were no differences in the VAS scores between the both-subcompartment group and the EPB group at 6 weeks (10 ± 6 versus 10 ± 7, mean difference -0.08 [95% CI -4.08 to 3.91]; p = 0.97). The same was true at 12 weeks (12 ± 13 versus 11 ± 15, mean difference 0.38 [95% CI -7.74 to 8.49]; p = 0.09). No adverse events related to treatment (such as tendon rupture, infections, and numbness) occurred in either group. However, skin hypopigmentation occurred at the final follow-up examination in both groups. The proportion of patients experiencing skin hypopigmentation in the EPB subcompartment group was lower than in the both-subcompartment group (33% [8 of 24] versus 67% [16 of 24]; odds ratio 0.25 [95% CI 0.08 to 0.83]; p = 0.02). CONCLUSION: Our data suggest that a US-guided steroid injection targeting the EPB subcompartment alone is as effective in terms of pain reduction as targeting both subcompartments in patients with de Quervain disease who have complete septation. Furthermore, an injection targeting the EPB subcompartment alone can reduce the dose of steroids used, perhaps thereby decreasing complications related to steroid injections. We recommend using only single-compartment injections in this context, even among patients with an intracompartmental septum. LEVEL OF EVIDENCE: Level I, therapeutic study.

The effectiveness of corticosteroid injection and splint in diabetic de Quervain's tenosynovitis patients: A single-blind, randomized clinical consort study.

BACKGROUND: There is no clear information on the efficacy of corticosteroids, and splints in the treatment of patients with diabetes mellitus (DM). The aim of this study was to compare the outcomes of isolated corticosteroid injection therapy with splint treatment with corticosteroid injection in patients with and without DM. METHODS: 84 diabetics, and 84 healthy patients with a diagnosis of de Quervain's tenosynovitis were included in our study. The patients were randomly distributed into four subgroups with and without DM. Groups 1 and group 2 consisted of diabetic patients, while group 3 and group 4 consisted of healthy patients. Corticosteroid injections were administered to groups 1 and 3, and corticosteroid injection and splint treatment were administered to groups 2 and 4. RESULTS: There was no significant difference in terms of age, gender, dominant/non-dominant hand, pre-treatment Quick Disabilities of the Arm, Shoulder and Hand score and visual analog scale scores score between the four groups. Quick Disabilities of the Arm, Shoulder and Hand and visual analog scale scores in the four groups were found to be significantly better than pre-treatment at the 12th month. Finkelstein test results were positive in 37.5% of the patients in the first group, 35% of the patients in the second group, 20% of the patients in the third group and 9.5% of the patients in the fourth group. Groups 1 and 2 and, groups 3 and 4 were compared to evaluate the effect of the splint. While forearm-based thumb splint affected the results positively in healthy individuals, it was determined that it had no effect on the results in diabetic patients. CONCLUSION: Although corticosteroid treatment is effective in the treatment of de Quervain's tenosynovitis in healthy and diabetic individuals, the results are worse in diabetic patients than in healthy patients. In addition, the use of splint with corticosteroid injection in healthy individuals positively affects the results, while it does not affect the results in diabetic patients.

Management of de Quervain Tenosynovitis: A Critical Analysis Review.

¼: 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. ¼: 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. ¼: 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. ¼: 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. ¼: 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.

Effects of local anaesthetics (neural therapy) on pain and hand functions in patients with De Quervain tenosynovitis: A prospective randomised controlled study.

OBJECTIVE: De Quervain tenosynovitis is the most common cause of lateral wrist pain. The diagnosis can be made with the Finkelstein test when pain is provoked with wrist ulnar deviation. Conservative treatment including rest, non-steroidal anti-inflammatory medication and physical therapy is applied first, then there may be a need for corticosteroid injections, and in resistant cases, surgery. The aim of this study was to evaluate the effectiveness of neural therapy (NT) on pain and hand functions in patients with De Quervain tenosynovitis. METHODS: A total of 36 patients admitted between May 2019 and March 2020 were randomly assigned to neural therapy (NT) and control groups. Hand rest and thumb spica splint were applied to all the patients, and NT interventions to the NT group only. A visual analogue scale (VAS) and the Duruöz Hand index (DHI) were used to measure pain and functionality at baseline, then at 1 and 12 months after the end of the treatment. RESULTS: The NT and control groups both showed improvements in VAS and DHI scores at 1 and 12 months compared with baseline (P < .001) according to within group comparisons. The VAS scores were significantly lower at both 1 and 12 months compared with baseline in the NT group (P < .001, P = .002 respectively). The DHI scores were lower in the NT group at 1 month (P = .009), and at 12 months there was no significant difference between the two groups (P = .252). No adverse effects were seen in any patient. CONCLUSION: NT seems to be effective in reducing pain and improving hand functions in patients with De Quervain tenosynovitis.

Methylprednisolone acetate injection with casting versus casting alone for the treatment of De-Quervain's Tenosynovitis: a randomized controlled trial.

OBJECTIVE: To compare the success of treatment between thumb spica cast with "methylprednisolone acetate injection" versus thumb spica cast alone for the treatment of de Quervain's disease as functional outcomes, complications and patient compliance. METHODS: A single blinded randomized controlled trial using a probability sampling technique was conducted from January 2014 to h February 2017at the Orthopaedic Unit II, King Edward Medical University / Mayo Hospital, Lahore. A total of 134 patients of both genders, between 30-60 years of age presented with wrist pain and diagnosed de Quervain's disease, were included in the study. Patients were randomly divided into two group by the computer allocation method. Patients in Group-A received thumb spica cast with methylprednisolone acetate and xylocaine injection while patients in Group-B were treated with thumb spica cast alone. The outcome variable was frequency of successful treatment which was noted and compared among the groups. RESULTS: Amongst the total 134 patients, the age of the patients ranged from 30 to 60 years with a mean of 37.16±5.15 years. Most of the patients were aged between 30 40 years (78.8%) followed by 41-50 years (21.2%). There were 38 (28.4%) male and 96 (71.6%) female patients in the study group with a male to female ratio of 1:2.5. In group-A mean VAS and Quick DASH score before treatment and after the treatment was statistically significant (p-value <0.001). In group-B mean VAS and Quick DASH score before and after the treatment was also significant (p-value <0.001) ( Table-2). CONCLUSIONS: The effectiveness of treatment was significantly higher in patients treated with thumb spica cast with methylprednisolone acetate injection as compared to thumb spica cast alone.

Prospective randomized comparison of ultrasonography-guided and blind corticosteroid injection for de Quervain's disease.

BACKGROUND: Ultrasonography (US)-guided corticosteroid injection (CI) has been attempted to improve injection accuracy in de Quervain's disease (dQD), but its role in improving clinical outcomes and decreasing skin hypopigmentation or atrophy was not established well. HYPOTHESIS: We hypothesized that the US-guided CI is superior to blind CI in symptom improvement and development of skin hypopigmentation or atrophy. PATIENTS AND METHODS: Forty-four patients (48 wrists) with dQD received ultrasonography-guided CI (24 wrists/22 patients, group A) or blind CI (24 wrists/22 patients, group B) between December 2016 and February 2018. The visual analogue scale for pain and the Patient-rated Wrist Evaluation (PRWE) were used for evaluation. Skin hypopigmentation or atrophy was evaluated using the modified Vancouver scar scale (mVSS) RESULTS: At 4 weeks post-injection, pain and PRWE scores improved for 22 wrists in group A and 21 wrists in group B. At 3 months post-injection, 10.0% (2/20) and 26.3% (5/19) of wrists in group A and B, respectively, had symptom recurrence after initial improvement. Improvement and aggravation rates were not significantly different between the groups. The incidence of skin hypopigmentation or atrophy was 69.6% (16/23 wrists) and 70.0% (14/20 wrists) in group A, and 59.1% (13/22 wrists) and 78.9% (15/19 wrists) in group B at 4 weeks and 3 months post-injection, respectively. The mean mVSS scores at the injection site in group A and B were 2.0 (0-4.0) and 1.8 (0-5.0) at 4 weeks post-injection and 2.4 (0-7.0) and 2.9 (0-6.0) at 3 months post-injection, respectively. The incidence and severity of skin hypopigmentation or atrophy were not significantly different between the groups at both time points. DISCUSSION: Pain and clinical outcomes significantly improved after CI in dQD. Pain, clinical outcomes, and the incidence and severity of skin hypopigmentation or atrophy were not significantly different between ultrasonography-guided and blind CI.

'The side of my wrist hurts': De Quervain's tenosynovitis.

BACKGROUND: Radial-sided wrist pain is a common patient complaint that can have a dramatic effect on the patient's productivity at work, sporting or artistic pursuits and activities of daily living. OBJECTIVE: The aim of this article is to outline key principles in the assessment and treatment of De Quervain's tenosynovitis. DISCUSSION: The correct diagnosis of this debilitating tendon condition and the seeking of early treatment yields excellent outcomes for patients. While there are numerous possible aetiologies, the pathophysiology is defined as a stenosing condition of the first dorsal compartment. Assessment elicits pain over the radial styloid that is caused by the restricted glide of the tendons. Ultrasonography has been shown to be useful in diagnosis and treatment planning, especially if an intercompartmental septum is present. Treatment involves corticosteroid injections and orthoses prescriptions. These should not be used in isolation; many other therapy techniques have been shown to be effective in the management of De Quervain's tenosynovitis.

Impact of Septated First Dorsal Compartments on Symptomatic de Quervain Disease.

BACKGROUND: The authors conducted this study to determine whether septation of the first dorsal compartment is more prevalent in de Quervain tenosynovitis, and whether this contributes to failure of corticosteroid injection therapy. METHODS: A retrospective review of 79 consecutive patients (85 wrists) with symptomatic de Quervain tenosynovitis treated with surgical release was performed. The number of corticosteroid injections performed preoperatively and the presence of first dorsal compartment septation determined intraoperatively were recorded. Correlation between the number of steroid injections and the presence of septation was evaluated. In addition, 48 matched cadaver upper extremities (96 wrists) that had not previously undergone surgery for de Quervain disease were evaluated for the presence of first dorsal compartment septation. The prevalence of septation was compared between matched wrists and against the surgically treated clinical cohort. RESULTS: In the clinical cohort, 61.2 percent of wrists contained a septated first dorsal compartment. There was no correlation between the presence of a septated first dorsal compartment and the number of steroid injections before surgical release. In the cadaver portion of the study, 72.9 percent of wrists contained septa. There was no significant difference in the prevalence of septated first dorsal compartments between groups. CONCLUSIONS: In the present study, the majority of wrists contained a septated first dorsal compartment, with no difference in the prevalence of septa between surgically treated patients and a cadaver sample that had not undergone prior surgical release. Furthermore, there was no correlation between the presence of septa and the number of preoperative corticosteroid injections administered. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Efetividade da infiltração de corticosteroides no tratamento de pacientes com tenossinovite estenosante de De Quervain: resultado terapêutico / Effectiveness of corticosteroid injections for treatment of patients with Quervain's tenosynovitis: therapeutic outcome / Efectividad de inyección de corticosteroides para el tratamiento de pacientes con tenosinovitis de De Quervain: resultado terapéutico

Introduction: Quervain's tenosynovitis, the most common inflammatory wrist disease, most prevalent in females and in the age group of 30 to 50 years, is characterized by the involvement of the synovial sheath of the first extensor compartment of the wrist, which includes the thumb long abductor tendons (ALP) and short thumb extensor (ECP) tendons. Despite the undefined etiology, multifactorial character is attributed as trauma, overload of repetitive exercises with wrist and hand, metabolic, rheumatic alterations and anatomical variations, such as the presence of two or more ALP and ECP tendons and osteofibrosal tunnel septum. Among the therapeutic alternatives is infiltration with corticosteroids. Material and Method: The therapeutic outcome was evaluated in 15 patients who underwent local corticosteroid infiltration using the DASH and PRWE questionnaires and Visual Analogue Scale. Results: Significant improvement was observed in the evaluated patients. Conclusion: Corticosteroid treatment is effective and safe(AU)

Prognostic effect of pain sensitization in patients with de Quervain's tenovaginosis receiving corticosteroid injection.

We investigated the influence of pain sensitization on the prognosis of de Quervain's tenovaginosis after a local corticosteroid injection. One hundred and fifteen patients with de Quervain's tenovaginosis who were treated with corticosteroid injection were recruited. We initially measured pain sensitization by assessing the patients' pressure pain thresholds in the mid-dorsal forearm and by administering a Pain Sensitivity Questionnaire. The pain score using a visual analogue scale, the result of Eichhoff's test, and the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire were assessed at baseline and at 6 and 24 weeks after the injection. The DASH scores at 6 weeks correlated slightly with higher Pain Sensitization Questionnaire scores, and the DASH scores at 24 weeks correlated moderately with higher Pain Sensitization Questionnaire scores and lower pressure pain thresholds. Lower pressure pain thresholds, higher Pain Sensitization Questionnaire scores, and heavy manual work were independently associated with a higher likelihood of persistent symptoms and signs after a local corticosteroid injection for de Quervain's tenovaginosis. Level of evidence: III.
