Timing of intra-lesion shaving for surgical treatment of chronic tophus

Management of Gout in the Hand and Wrist

Gout, or monosodium urate deposition disease, is the most common form of inflammatory arthritis that affects almost 4% of adults in the United States.Medical management involves lifestyle modifications and urate-lowering therapy to reduce the frequency of gout flares, decrease the tophi size, and improve upper extremity function. Goals for surgical management of gout include functional optimization, symptomatic treatment, and cosmetic restoration.This article focuses on the medical and surgical treatment of the common manifestations of gout in the upper extremity including tophi, tenosynovitis, joint contractures, neural compression, and arthropathy.

Surgical Treatment of Hand and Foot Gout Stone and Influence Factors on Prognosis

Purpose

To explore the technique of surgical treatment of hand and foot gout stone by using 3D CT reconstruction images and influence factors on prognosis.

Method

48 cases of hand and foot gout were treated surgically and retrospective analyzed. Before operation, we used 3D CT reconstruction images to check the accurate site and amount of uric acid (white chalk foam) deposition. Different surgical methods were applied depending on the different deposition site of urine acid stone. The frequency of gout attack and blood uric acid was compared before and after surgery. Patients were followed up to observe the recovery and recurrence and then analyzed the reason of unsuccessful healing.

Result

Sutures were removed 2 weeks after operation in all cases. The frequency of gout attack and blood uric acid of patients 3 months after operation was lower than those before operation, and the differences were statistically significant. Follow-up ranged from 1 to 3 years, with an average of 1.8 years. Three cases were not followed up. The remaining 45 cases were healed in the first stage. 40 cases had improved joint function, increased range of motion, and relieved discomfort after movement. 5 cases had no improvement in joint function after operation, and 3 of them had gout stone recurrence (nonoperative area) and were treated by second hospital operation.

Conclusion

Surgical treatment of gout stone in hand and foot under the guidance of three-dimensional CT reconstruction image can effectively alleviate the local symptoms of gout stone and improve the function of hand and foot. Deep tissue can be thoroughly washed by the pressure of pulse gun after resection of the lesion, which can reduce the incidence of gout stone. Malnutrition, hypoproteinemia, and residual urine acid in the wound are the main reasons for unsuccessful healing.

Ulcerated Tophaceous Gout

Gout is a disease that occurs in response to the presence of monosodium urate (MSU) crystals typically within joints. Patients with gout may develop a chronic deposition of monosodium urate crystals within or around joints, cartilage, tendons, peri-articular, and subcutaneous tissue. This condition is termed "tophaceous gout." Ulceration of the skin by tophi is very uncommon. Literature regarding the clinical course and the management of ulcerated tophi is limited and, therefore, treatment options are not well established. We hereby present a case of a 46-year-old male who presented to our facility with poorly controlled polyarticular tophaceous gout complicated by ulcerated tophi. Our hope is to contribute to the limited knowledge of this rare disease process and to contribute toward formulating the best management approach.

En Masse Excision and Curettage for Periarticular Gouty Tophi of the Hands

BACKGROUND

Despite increasing disease prevalence, there remains a paucity of data examining surgical treatments for gouty tophi. This article assesses en masse excision and curettage of articular tophi involving the hands and shows that carefully planned and precisely executed surgery can consistently alleviate pain, preserve function, and enhance the aesthetics of afflicted hands.

METHODS

A retrospective review was conducted of all consecutive patients who underwent surgical excision of tophaceous deposits from the upper extremity. All patients had an established diagnosis of gout and had been treated with urate-lowering medication. All tophi were substantive in size and were causing significant digital joint dysfunction and disfigurement with variable skin ulcerations.

RESULTS

The study group included 12 patients with 24 tophaceous deposits excised from the metacarpal and interphalangeal joints; 2 deposits were also concomitantly excised from the wrist and 2 from the elbow. The study group included 8 men and 4 women, with an average age of 67 years. Follow-up evaluation ranged from 2 to 15 years. All patients underwent successful tophus excision with restoration of tendon excursion and joint mobility without wound complications. All regained high levels of function, and all reported satisfaction with their outcome. On follow-up for as long as 15 years, recurrence has not been observed and secondary surgery has not proved necessary.

CONCLUSIONS

This study indicates that surgical excision of articular tophi of the hands can provide long-term improvement in function and aesthetics with minimal risk of wound complications or recurrence.

Operative Management of Gouty Tophi in the Region of the Olecranon: A Case Series

Background

Tophaceous gout affecting the olecranon region can result in local discomfort, skin ulceration, secondary infection, and considerable disability if left untreated. However, there are limited reports of outcomes, including postoperative complications and recurrence after surgical excision of tophaceous gout deposits at the elbow. The aim of this study is to present our surgical technique and minimum one-year outcomes after surgical excision of tophaceous gout involving the elbow.

Methods

A retrospective chart review was performed on all patients from a single surgeon's practice who underwent surgical excision of gouty tophi of the elbow between January 2016 and December 2019. The indications for surgical excision of tophi included failure of medical management, presence of skin ulceration, and/or large gouty tophi. The relevant data pertaining to patient demographics, preoperative findings, intraoperative findings, surgical pathology reports, and short-term postoperative complications were collected through retrospective chart review. Patients were subsequently contacted for a follow-up telehealth visit to assess recurrence of gouty tophi, functional outcomes, and range of motion (ROM) measurements.

Results

Six male patients underwent 7 total procedures (1 bilateral elbow) during the study period. The mean age of the cohort at the time of surgery was 56.0 ± 7.1 years (range: 45.3-63.5). The mean size of the swelling in 2 maximum dimensions was 5.8 × 3.4 cm. There were no intraoperative or immediate postoperative wound complications. There was no recurrence of gouty tophi at a mean follow-up time of 30.8 months (range: 14.0-43.5). Patients reported physiologic ROM (mean flexion-extension arc of 2°-134°) with no pain at final follow-up.

Conclusion

Surgical treatment of tophaceous gout of the elbow is associated with a low risk of wound complication and recurrence.

Gouty Involvement of Foot and Ankle: Beyond Flares

The foot and ankle are common locations of deposition of monosodium urate (MSU) crystals, as indicated by the clinical manifestations presented by patients with gout, which are not limited to the acute inflammation of the big toe. We present a narrative literature review aimed to update the gout involvement of foot and ankle and how it affects the quality of life. Cumulative reports indicate that gout, even at the non-tophaceous stage, could cause pain, gait impairment and limit the mobility at lower limbs. These patients may present difficulties in some activities of daily living such as choosing footwear, thus leading to an impaired quality of life. Gout is a curable disease by dissolving MSU crystals but remains unclear how this could modify some of these foot and ankle manifestations, especially when structural damage has already occurred. Furthermore, a collaboration between rheumatologists and podiatrists seems helpful to understand, relieve these symptoms and improve the quality of life in gouty patients.

Beyond Medical Treatment: Surgical Treatment of Gout

PURPOSE OF REVIEW

Medical treatment with urate-lowering therapy (ULT) is efficacious. A recent publication suggested that surgery in gout is more prevalent than previously reported. This revelation led us to review what is known about surgical treatment of gout.

RECENT FINDINGS

The Google Scholar database (January 1, 2014-January 1, 2020) found 104 publications with a total of 169 gout patients, with an average disease duration of 6.7 years. Most (68%) were not on ULT. The mean pre-operative serum urate levels were 9.19 mg/dL. One hundred thirteen patients underwent tophi excision, while in 33 patients, tophi were found during surgery. The majority of the surgeries were performed in Asia and Europe. Most patients were not taking ULT at the time of surgery, leading to hyperuricemia. This can result in tophi reformation post-surgery. The role of surgery should be a last-line treatment and until recently has only been demonstrated through case reports.

Treatment of tophaceous gout: When medication is not enough

OBJECTIVES

To review the literature concerning surgical intervention of tophaeceous gout and propose clinical circumstances for when it may be considered.

INTRODUCTION

Tophi develop in approximately 12-35% of patients with gout. Tophaceous disease is usually preventable given the availability of effective urate lowering therapies (ULT) including allopurinol, febuxostat, probenecid, lesinurad, and pegloticase. Despite medical therapy, there remains a subset of patients who develop significant complications of tophi including infection, ulceration, and entrapment neuropathy. Tophi in close proximity to joints can cause joint instability, severely limited range of motion, and significant functional impairment. For the rare circumstance when a tophus is causing an urgent complication or if a patient has a contraindication to all available ULTs, surgery may be an appropriate option. This review summarizes the published experience with surgical interventions for tophaceous gout and offers recommendations for its consideration.

METHODS

Using Medline and Google Scholar, all available series of surgery for tophaceous gout were reviewed.

RESULTS

Overall, 7 published surgical series were identified. In all, 6 of these 7 series were published between 2002 and 2014. The reported outcomes of surgical interventions for tophaceous gout were generally positive without major post-surgical complications.

CONCLUSION

Although medical therapy with ULTs should be the first-line approach to tophaceous gout, surgery should be considered for the rare patient with impending or severe, debilitating complications including infections, entrapment neuropathy or those at risk for permanent joint destruction. In these selected clinical circumstances, surgical intervention for tophaceous gout may be appropriate.

Evolution of gout: "malignant" change over time?

Gout is a common entity; yet it is such a great mimicker in its imaging features that it can confuse clinicians and radiologists alike, sometimes leading to unnecessary investigations and treatment. We present a case of a 52 year old male renal transplant patient who presented with a slow growing mass in his left shin. The initial radiograph demonstrated a non-aggressive looking calcified lesion. A fine needle aspiration demonstrated this lesion to be gout deposition. The lesion was unchanged in the following eight years until the patient reported a sudden growth in size. Imaging showed features of an aggressive lesion with disruption of the previous calcification as well as enhancement on magnetic resonance imaging. Surgical excision biopsy was performed in view of the worrisome features on imaging and the histology showed tophaceous gout. Following description of our case, we reviewed the clinical and imaging features of gout and discussed its differential diagnoses.
