Trigger Finger or De Quervain Tenosynovitis after Surgical Treatment for Carpal Tunnel Syndrome / Dedo em gatilho ou tenossinovite de De Quervain após tratamento cirúrgico da síndrome do túnel do carpo

Abstract Objective To evaluate the open surgical treatment for carpal tunnel syndrome as a risk factor for the development of stenosing tenosynovitis that results in trigger finger and De Quervain disease. Materials and Methods A retrospective study analyzing the medical records of patients submitted to open surgical release of carpal tunnel syndrome between 2010 and 2021 in a secondary- and tertiary-level hospital. The following data were collected: pathological history, duration of the follow-up after the surgical treatment for carpal tunnel syndrome, development of trigger finger or De Quervain tenosynovitis, affected fingers, and the interval between the end of surgery and symptom onset. Results We evaluated 802 patients of both genders and with a mean age of 50.1 (±12.6) years. The mean follow-up was of 13 (±16.4) months. The mean time until the development of trigger finger was of 61.4 months, and of 73.7 months for De Quervain disease. The incidence of development of De Quervain disease was of 4.12%, and for trigger finger it was of 10.2%. The most affected digits were the thumb (47.6%), the middle (24.4%), and the ring finger (8.54%). Age was the only factor that showed an association with the risk of developing trigger finger, with an increase of 2% for each increase in age of 1 year. Conclusion The incidence rates for the development of De Quervain disease (4.12%) and trigger finger (10.2%) after the surgical treatment for carpal tunnel syndrome were like those described in the literature. Only age was a factor that influenced the development of trigger finger.

Research progress of stenosing tenosynovitis of radial styloid process based on anatomical structure / 中国骨伤

Stenosing tenosynovitis of styloid process of radius(de Quervain's disease) which abductor pollicis longus and extensor pollicis brevis in the first extensor chamber are affected by resistance when sliding, the incidence is affected by anatomical variations. Symptoms, signs and auxiliary examinations can diagnose the disease. Slight dQS can be improved by rest, brace, restriction activities, and oral medications. Chinese medicine and physiotherapy also reduce the disease. Needle knife therapy is a Traditional Chinese medicine minimally invasive surgery, which is also a step-by-step treatment between conservative treatment and open surgery to loosening the compression of the first extensor chamber. Steroid injection is a more common treatment in this disease, and its efficacy is related to the accuracy of the injection and is affected by the severity of the patient's anatomical variation. Identifying the spacing within the first extensor chamber under ultrasound can help patients better choose conservative or surgical treatment. Surgical treatment can more completely change the condition of dQD from anatomical structure, and clinical should pay attention to the choice of surgical procedure to improve the efficacy and reduce the occurrence of surgical complications. This article discusses the pathogenesis, diagnosis and treatment of the disease from the perspective of anatomical structure. It mainly analyzes the therapeutic targets and the clinical application, which aims to provide reference for the diagnosis and treatment of de Quervain disease.

The Relationship between Physical Findings and the Recurrence after Steroid Injection in De Quervain's Disease

PURPOSE: The purpose of this study was to evaluate the effect of steroid injection according to the stage of Finkelstein's test and the severity of tenderness on radial styloid in de Quervain's disease. METHODS: Between January 2011 and December 2012, a total of 57 patients (57 wrists) treated with steroid injection in de Quervain's disease were enrolled on this study. The severity of tenderness, the stage of Finkelstein's test and pain score using visual analogue scale (VAS) were assessed before steroid injection. And the effect of steroid injection was assessed until one year after steroid injection. The relationship between the recurrence of de Quervain's disease after steroid injection and pre-injection findings including tenderness, Finkelstein's test and VAS was assessed. RESULTS: The success rate of steroid injection was 71.9% (41/57 patients). The outcome of steroid injection was not significantly related to the severity of tenderness (p=0.648), the stage of Finkelstein's test (p=0.530) and VAS score (p=0.607). CONCLUSION: The tenderness on radial styloid and the Finkelstein's test are important physical findings for the diagnosis of de Quervain's disease. However, the severity of tenderness and the stage of Finkelstein's test were not showed as predictive factors for the outcome.

Ibuprofen timing for hand surgery in ambulatory care

OBJECTIVE: To evaluate the effect of pre-operative administration of ibuprofen on post-operative pain control vs. early post-operative administration for hand surgery procedures performed under local anaesthesia in ambulatory care. METHODS: Candidates to trigger finger release by De Quervain tenosynovitis and carpal tunnel operation under local anesthesia were enrolled in the study. Group A received 400 mg ibuprofen before the operation and placebo after the procedure; group B received placebo before the operation and ibuprofen 400 mg at the end of the procedure; both groups received ibuprofen 400 mg every 6h thereafter. Visual analogue scale (VAS) was measured at fixed times before and every 6h after surgery, for a total follow-up of 18h. RESULTS: Groups were similar according to age, gender and type of surgery. Median VAS values did not produce any statistical significance, while there was a statistically significant difference on pre-operative and early post-operative VAS values between groups (A -8.53 mm vs. B 3.36 mm, p=0.0085). CONCLUSION: Average pain levels were well controlled by local anesthesia and post-operative ibuprofen analgesia. Pre-operative ibuprofen administration can contribute to improve early pain management. Level of Evidence II, Therapeutic Studies.

Risk of the Repeated Local Steroid Injection: Rupture of the Extensor Mechanism at Zone V

Indicators for local steroid injection on the hands include trigger finger, De Quervain's disease, carpal tunnel syndrome and trapeziometacarpal joint arthritis. Local steroid injection is an effective technique for rapid alleviation of symptoms and return to daily life. Complications following local steroid injection include depigmentation of the skin, subcutaneous fat atrophy, infection and tendon rupture. Tendon rupture and infection rarely occur as severe complications, and local steroid injection should not be abused or misused. The authors experienced a rupture of the extensor mechanism at extensor zone V after repeated local steroid injection to treat vague pain in the second metacarpophalangeal joint, followed by reconstruction of the extensor mechanism through tendon transfer and sagittal band reconstruction. We herein report a case with the literature review.

Surgical Release of the First Extensor Compartment for Refractory de Quervain's Tenosynovitis: Surgical Findings and Functional Evaluation Using DASH Scores

BACKGROUND: Few studies have evaluated surgical outcomes in patients with refractory de Quervain's disease using validated outcome measures. We assessed the clinical outcomes of dorsal release of the first extensor compartment for the treatment of de Quervain's disease using the disabilities of the arm, shoulder and hand (DASH) score. METHODS: From October 2003 to May 2009, we retrospectively evaluated 33 patients (3 men and 30 women) who underwent surgical treatment for de Quervain's disease. All patients had a positive Finkelstein test and localized tenderness over the first dorsal compartment. All operations were performed under local anesthesia. A 2-cm-long transverse skin incision was made over the first extensor compartment and the dorsal retinaculum covering the extensor pollicis brevis was incised longitudinally. Preoperative and postoperative clinical evaluation included the use of DASH score, Finkelstein test, and visual analogue scale (VAS) score. RESULTS: In 18 patients (55%), the extensor pollicis brevis tendon compartment was separated from the abductor pollicis longus compartment. Eight patients had intracompartmental ganglia in the extensor pollicis brevis subcompartment. All patients except one had negative sign on Finkelstein test at the last follow-up. The average VAS score decreased from 7.42 preoperatively to 1.33 postoperatively (p < 0.05), and DASH score was improved from 53.2 to 3.45 (p < 0.05). There were no postoperative complications such as subluxation of the tendon of the first dorsal compartment or injury to the sensory branch of the radial nerve. CONCLUSIONS: Intracompartment ganglia and the separate septum of extensor pollicis brevis are often related to de Quervain's disease. The release of the first extensor compartment for refractory de Quervain's disease resulted in good clinical outcomes with minimal morbidity.

Anomalous origin of the Abductor Pollicis Longus (APL): clinical and surgical applications

The Abductor Pollicis Longus (APL) is known to have a big variety in its number of insertion tendons.Because of that, studies about variations in its origin are not frequently achieved like studies about its insertionforms. This study describes an anatomic variation of the Abductor Pollicis Longus, with an anomalous venteroriginated of the inferior portion of the lateral border of the radio. Surgical and clinical implications are inrelation principally with the big number of tendons of insertion of the APL, but there are related cases inthe literature in that additional venter of this muscle also can be involved in the physiopathology of clinicalsyndromes, like the tenosynovitis of de Quervain

La ultrasonografía en el estudio de la patología regional de la mano y la muñeca: [revisión] / Ultrasound in the evaluation of hand and wrist disorders: [review]

La mano y la muñeca son frecuentemente implicadas en síndromes de dolor regional, inflamatorios y degenerativos. La ultrasonografía ha demostrado ser más sensible que los exámenes clínicos y de radiología convencional para la detección de sinovitis y erosiones. También ha podido revelar una participación subclínica en pacientes con artritis crónica. Las indicaciones de la ultrasonografía a nivel de la mano y la muñeca son amplias e incluyen el diagnóstico de la afección articular y el tendón, la patología de poleas, los cambios morfoestructurales a nivel del nervio mediano en el túnel carpiano; puede servir como guía para las infiltraciones, así como para la valoración del tratamiento en pacientes con artritis crónica. El objetivo de esta revisión es mostrar el resultado de las alteraciones más frecuentes en las que la ultrasonografía ha demostrado ser útil.

The hand and wrist are frequently involved by regional pain syndromes, inflammatory and degenerative conditions. Ultrasonography had demonstrated to be more sensitive than both clinical examination and conventional radiology for the detection of synovitis and erosions. It has also able to reveal a subclinical involvement in patients with chronic arthritis. The indications of ultrasonography at hand and wrist level is wide and include: diagnosis of joint and tendon involvement, pulleys pathology, morphostructural changes at median nerve level into to carpal tunnel, guidance for infiltrations into and treatment monitoring in patients with chronic arthritis. The aim of this review is to show the most frequent alterations in which ultrasound has proven useful.

[De Quervain's tenosynovitis imaging: ultrasonography versus magnetic resonance imaging]

To determine the diagnostic efficiency of ultrasonography [U/S] and magnetic resonance imaging [MRI] in detecting de Quervain's tenosynovitis. Forty wrists of 29 symptomatic patients [21 females and 8 males] were selected during a 12 months period. Patients with suggestive clinical de Quervain's tenosynovitis underwent both wrist ultrasonography and magnetic resonance imaging, to determine changes in the first dorsal compartment thickness in both genders. T1-weighted images were obtained in axial, sagittal and coronal planes. Whereas, T2-weighted gradient echo images and T2-weighted fat saturation images were performed in axial and coronal planes. Cohen Kappa was used for statistical analysis. The ultrasonographic results among all diseased wrists showed 100% tendon thickening, 97.5% peritendinous edema, 72.5% decreased tendon mobility and 70% septation. The magnetic resonance imaging results showed 95% tendon thickening, 85% peritendinous edema, 62.5% increased tendon signal, 60% septation, 55% subcutaneous edema, and 45% synovial thickening among the whole group. All values demonstrated differences among genders and more prominent in females.The prime reliable finding is in respect to superiority of ultrasound in all comparable criteria which was confirmed by statistical results. Ultrasonography is considered the favorite technique to validate the clinical diagnosis. It gives special accuracy and high diagnostic capability even in early stages. Magnetic resonance imaging could be significant in doubtful clinical diagnoses not confirmed by ultrasonography. In addition, magnetic resonance imaging has advanced capability to detect other soft tissue and bone marrow abnormalities

Septated de Quervain's Disease with MRI Images: A case report

De Quervain's disease is the most common form of tenosynovitis, which causes disability in daily living and occupational activity. Anatomical variations in the first extensor compartment including separate comparment influenced the effects of treatment. A 45-year-old woman had severe pain on wrist and suffered in activity of daily living after motor vehicle accident. She had swelling and tenderness upon the radial styloid process, and more aggravated pain by Finkelstein's maneuver test. The magnetic resonance imaging (MRI) scans showed severe peritendinous edema within the synovial sheath, increased signal intensity within the tendons. Also, the images revealed a thickened septum between abductor pollicis longus and extensor pollicis brevis. Corticosteroid was injected on both sides of the septum. We report a case of definite septum of de Quervain's disease via MRI scans.

Surgical results treatment of the stenosing tenovaginitis or De Quervain disease in Aleppo University Hospital

Is an inflammatory disease affecting the tendon sheasths of the abductor pollicis longus and extensor pollicis brevis passing during the first compartment of the wrist. The inflammatory will cause soft tissue swelling leading to compartment stenosis this clinically leads to acute or chronic pain in the wrist especially in the region and eventually to thumb or hand. First: under general anesthesia,regional,local anesthesia, released the tendons sheaths and retinaculumfor the abductor pollicis longus, extensor pollicis brevis,A thumb splints eventuallyis put post operatively for 7-10 days. Second: skin inscision is performed obliquely or longitudinally. Third: The orthopaedist must see via the inscision site the tendons release from the distal end of LISTER'S hump and there free moveements. Fourth: thumb splint is applied for chronic patients who didn't show any signs of improvement or preserved treatement [more than once injection+splinting] Our study incluted [40] patients diagnosed de quervan's. Patients were selected above the age of twenty years old. Females are affected more than males with a rate F:M=3:1. Patients were classified according to age into 4 groups: [20-30]; [31 -40];[4 1-60]; more than 60 years old. The highest incidence of disease was found in the second age group [3 1-40]. By studying the distribution of males/females in all age groups :we found that the incidence rate of males less than females under 40 years old the incidence rate of females is higher than males in the age -males use of thumb is the most important frequent cause of de quervan's patients in both age groups. -Right hand is slightly more affected than left hand, due to dependence patients an there right hand in performing there works. -Pain, tenderness, swelling in distal lateral forearrm and stifness of the thumb wette seen in all patients. Local anesthesia was used in all cases except for three cases regional anesthesia, and older patients under general anesthesia. Cases of using thumb's supporting splint:- [10] patients needed thumb's supporting spint, in different time, for different times intervals and for different causes: - [4] patients was applied supporting thumb splint directly post operation, due to adhesion the supporting as applied for only 10 days. - [1] patient directly post operation due to excesion of the sub tendinial cyst under the abductor pollicis longuss nd extensor pollicis brevis tendons and thumb's splint was applied for 15 days. - [3] patients the next days post operaion due to adema and they were applied for 7 days. - [2] patients directly post operations to preventive precaution after long operation, thumb's splint was applied for 15 days

De Quervain's Disease Associated with Osseous Septum: A Case Report / 대한정형외과학회잡지

A septum between the abductor pollicis longus tendon and the extensor pollicis brevis tendon in the first extensor compartment is frequently encountered during the surgical treatment of de Quervain's disease. But de Quervain's disease associated with a bone tumor and an osseous septum is very rare. We treated a patient with de Quervain's disease who had a bone tumor and an osseous septum between the abductor pollicis longus tendon and the extensor pollicis brevis tendon in the first extensor compartment. After the excision, the pain was relieved and Finkelstein's test was negtive. We report upon this case, and includea brief review of the literature.

By stepwise multiple regression analysis with dichotomization of musculoskeletal disease, the following odds ratios were significantly high (p<0.05)-sex (2.707) and age(l.926).

The Treatment of de Qurvain's Disease / 대한정형외과학회잡지

We treated the 90 wrists (83 patients) with de Quervain's disease, and studied retrospectively the factors affecting the result of treatment, and the results of several treatment modalities, compared with published series of this disease. There was significant association between outcome and duration of symptoms before treatment, but age, sex, associated disease, and hand dominance were not associated(chi-square test, p < 0.05). And 75 wrists received single injections of steroid and local anesthetic into the tendon sheaths with complete pain relief in 59 wrists (69%). Furthermore, an additional injection gave pain abatement in 6 wrists. And regardless of treatment method, 95% of the whole patients had satisfactory outcome at a mean of 54 months (minimum follow-up, 45 months). We concluded that injection of steroid is the preferred initial treatment in de Quervain's disease, giving complete and lasting relief in 87% of cases.
