Surgery for scleroderma of the hand

The Impact of Tobacco Smoking on Systemic Sclerosis, Idiopathic Inflammatory Myositis, and Systemic Lupus Erythematosus

This narrative review aims specifically to explore the relationship between tobacco exposure and systemic sclerosis (SSc), idiopathic inflammatory myositis (IIM), and systemic lupus erythematosus (SLE). Relevant articles were obtained by searching key terms such as "tobacco," "smoking," "scleroderma," "myositis," "lupus," and "Sjögren's" in PubMed and Google Scholar databases. The selected articles ranged from the years 2010 to 2023. Inclusion criteria were based on the relevance and contribution to the field of study. Systemic sclerosis is a complex condition involving multiple immune cell lines that can be influenced by tobacco. However, the existing literature does not provide sufficient evidence to support an increased risk of SSc in smokers or the impact on treatment options. Cigarette smoking does increase the risk of skin ulcerations in SSc patients. In addition, cigarette smoking has been associated with IIM through genetic and molecular mechanisms. Smokers with dermatomyositis or polymyositis are at an elevated risk of atherosclerosis and interstitial lung disease. Similarly, smoking in patients with SLE increases the risk of organ damage, thrombosis, and disease severity compared with non-smokers. Smokers with SLE also have more difficulty in controlling disease flares compared with non-smokers. Tobacco exposure can lead to secondary complications in patients with IIM and SLE, although the course of treatment may not differ significantly. No definitive conclusions can be drawn to the clear relationship between tobacco smoking and Sjögren's's syndrome.

Digital artery reconstruction with interposition vein graft: impact on secondary Raynaud's phenomenon

OBJECTIVE

Patients with secondary RP show a wide range of symptoms depending on the condition of vascular structures. If the symptoms are localized to specific fingers and angiography reveals a discrete segment of occlusion of a proper digital artery, we perform proper digital artery reconstruction with an interposition vein graft. The objective of this study was to evaluate the results of the surgery in patients with chronic hand ischaemia.

METHODS

A retrospective chart review was performed on patients who underwent proper digital artery reconstruction. Each digit that underwent grafting was analysed separately. The results of surgical intervention and recurrence based on patient symptoms were evaluated. Cox proportional hazards regression models were used to identify independent risk factors associated with recurrence, and the Kaplan-Meier method was used to predict the 5-year recurrence-free rate.

RESULTS

A total of 79 digits from 57 patients were included in this study. The majority of patients demonstrated resolution of ischaemic pain and ulceration (97.5% and 95.3%, respectively). Recurrence occurred in 16 (20.3%) patients during the follow-up period. In two cases (2.5%) surgery had no effect. In the multivariate Cox regression analysis, smoking and concomitant periarterial sympathectomy were significant factors associated with recurrence. In the Kaplan-Meier analysis, the 5-year recurrence-free rate in the total study population was 69.3%.

CONCLUSIONS

Digital artery reconstruction using an interposition vein graft is an effective procedure for improving ischaemic pain and ulceration in patients with RP. Smoking and concomitant periarterial sympathectomy were significantly associated with recurrence.

Neurectomy of the Nerve of Henle Associated with Periarterial Sympathectomy for Management of Intractable Raynaud Phenomenon

BACKGROUND

In periarterial sympathectomy for intractable Raynaud phenomenon, the extent of adventitectomy and postoperative outcomes and hand perfusion assessment tools remain debatable. The authors evaluated the outcome of neurectomy of the nerve of Henle combined with ulnar tunnel release and periarterial adventitectomy in the treatment of refractory Raynaud phenomenon using objective measurements and patient-reported outcomes.

METHODS

Nineteen patients with 20 affected hands were prospectively enrolled and underwent the proposed procedures from 2015 to 2021. Relevant data, including Michigan Hand Outcomes Questionnaire and 36-Item Short Form health questionnaire scores, were documented for analysis during a 3-year follow-up.

RESULTS

The average ingress value of the three measured fingers (index, long, and ring) on indocyanine green angiography increased after surgery ( P = 0.02). The median number of ulcers decreased ( P < 0.001), and the median digital skin temperature increased ( P < 0.001). Questionnaire scores showed improvement in physical aspects, such as overall hand function ( P ≤ 0.001), activities of daily living ( P = 0.001), work performance ( P = 0.02), pain ( P < 0.001), physical function ( P = 0.053), and general health ( P = 0.048), and mental aspects, such as patient satisfaction ( P < 0.001) and mental health ( P = 0.001). The average indocyanine green ingress value of the three measured fingers significantly correlated with the patient-reported outcomes, including overall hand function ( r = 0.46, P = 0.04), work performance ( r = 0.68, P = 0.001), physical function ( r = 0.51, P = 0.02), and patient satisfaction ( r = 0.35, P= 0.03).

CONCLUSIONS

The proposed surgical procedures provided satisfactory outcomes, both subjectively and objectively, over a follow-up period of up to 3 years. Indocyanine green angiography may provide rapid and quantitative measurements for perioperative hand perfusion assessment.

Distal periarterial sympathectomy surgery for chronic digital ischemia: A systematic review of the literature

Objective

This study assesses the efficacy of distal periarterial sympathectomy in treating chronic digital ischemia by evaluating clinical outcomes of surgery.

Methods

A systematic literature review of distal sympathectomy for chronic digital ischemia was conducted. Data extracted included study design, patient statistics, aetiology, follow-up duration, sympathectomy level, and surgical outcomes.

Results

21 studies were analysed, containing a total of 337 patients, 324 hands, and 398 digits. Patient age ranged from 23.2 to 56.6 years. Causes of ischemia included Scleroderma, Raynaud's disease, atherosclerosis/Buerger's disease, systemic lupus erythematosus/discoid lupus, undifferentiated rheumatic disorder/mixed connective tissue disease, CREST syndrome, trauma and unknown diagnoses. Common digital artery sympathectomy was mostly performed. Follow-up spanned 12-120 months.

Outcomes

Distal sympathectomy led to reduced pain in 94.7 % patients. Complete resolution of ulceration was seen in 73 % patients. Subsequent amputation was required in 28 % patients. Other complications were reported in 24.1 % patients.

Conclusions

This study indicates that distal periarterial sympathectomy may effectively treat chronic digital ischemia, offering pain relief and resolution of digital ulceration. However, risks of complications and amputation persist. Further research is required to inform patient selection and establish the optimal technique and extent of distal sympathectomy surgery, before it can be considered a valid treatment option.

Screening tool development for hand surgery referrals in systemic sclerosis

BACKGROUND

Systemic Sclerosis (SSc) patients may need hand surgery.

OBJECTIVE

To develop a screening tool for rheumatologists to identify potential candidates with systemic sclerosis for hand surgery, optimizing referrals.

METHODS

A pilot cross-sectional study from January 2015 to December 2016.

SAMPLE SIZE

51 participants.

INCLUSION CRITERIA

≥ 18 years old, meeting the 2013 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for SSc and hand impairment.

DATA COLLECTED

age, sex, race, disease duration, SSc subtypes, vasodilator use, skin thickness, finger stiffness, presence of Digital Ulcers (DU) and/or calcinosis, presence of Raynaud's Phenomenon (RP) attacks, health status and disability, disease status, pain intensity and functional status of the hands. Data were analyzed by a multivariate logistic regression model.

RESULTS

Fulfillment of surgical criteria: 68.8%. The surgical group had higher scores on the HAQ-DI (1.39 vs. 0.96, p = 0.032) and CHFS (25.0 vs. 12.0, p = 0.005) questionnaires, and a higher frequency of DU (91.43% vs. 18.75%, p < 0.0010), calcinosis (60.0% vs. 0.0%, p < 0.001), use of vasodilators (100.0% vs. 75.0%, p = 0.007) and digital stiffness (28.57% vs. 0.0%, p = 0.017). The presence of DU increased the chance of surgical indication by 46.2 times (ORIC 95% = 8.23 to 259.49). The statistical model showed good accuracy (86.3%, p < 0.001), sensitivity (91.4%), and specificity (81.2%).

CONCLUSION

The presence of DU in SSc could be used as a screening feature for early identification and referral of potential candidates for hand surgery.

Considerations When Performing Arthrodesis in the Scleroderma Hand

BACKGROUND

Hand deformities secondary to scleroderma can limit activities of daily living and be associated with substantial disability. This study aimed to evaluate the outcomes following arthrodesis performed to treat digital contractures secondary to scleroderma.

METHODS

We performed a retrospective review of all patients with scleroderma who underwent arthrodesis by a single surgeon from 2015 to 2020. We collected demographic information, operative variables, and outcomes variables. Our primary outcome was occurrence of any postoperative complication, which we defined to include wound dehiscence, digital ischemia, malunion, nonunion, cellulitis, and osteomyelitis. We calculated descriptive statistics and performed all analyses at the joint level.

RESULTS

We identified 9 patients who underwent arthrodesis of 19 joints. All patients were women with a mean age of 55.3 years. At the time of surgery, most patients were taking disease-modifying antirheumatic drugs (DMARDs). Kirschner wires (K-wires) were used in most cases (n = 18), 15 of which were removed uneventfully at an average of 4.8 months after surgery. With a mean follow-up time of 15.4 months, the overall complication rate was 5.3% (n = 1). This patient developed digital ischemia in 1 of 4 operative digits, which became gangrenous and required amputation.

CONCLUSIONS

Our study suggests that arthrodesis can be performed safely in the scleroderma hand, even when patients are taking DMARDs. Given the uneventful K-wire removal in all joints and the high risk of exposure of buried hardware in this population, we recommend nonpermanent placement of K-wires. Hand surgeons may consider arthrodesis in the scleroderma hand before proceeding to revision amputation.

Considerations for Hand Surgery in Patients With Scleroderma

Systemic sclerosis (scleroderma, SSc) is an autoimmune disease that causes significant dysfunction to multiple organ systems, including the musculoskeletal system. It poses significant challenges to the hand surgeon, including calcinosis, ischemic changes, Raynaud phenomenon, tendinopathies, synovitis, and joint contractures. Patients with SSc also suffer from multiorgan dysfunction, which makes them high-risk surgical patients. The hand surgeon must understand the pathophysiology, treatment strategies, and special operative considerations required in this population to avoid complications and help maintain or improve hand function.

Scleroderma and Raynaud Phenomenon: The Cold Truth Regarding the Use of Operative Management

BACKGROUND

Raynaud phenomenon, with and without scleroderma, is a common vasospastic condition that manifests with extremity pain and skin discoloration. When conservative management fails, complications such as ischemia, ulceration, and gangrene may warrant surgical intervention. The purpose of this study was to determine the risk factors and use of surgical intervention in this population.

METHODS

A national insurance claims-based database with patient records from the Centers for Medicare and Medicaid Services was used for data collection. Patients with first diagnoses of Raynaud phenomenon, scleroderma, or both between 2005 and 2014 were identified. Primary outcomes included the presence of upper extremity amputation or vascular procedure, and history of amputation within 5 years of a vascular procedure. Secondary outcomes included hospital admissions, upper extremity wounds, and amputation within 1 year of diagnosis.

RESULTS

The Raynaud phenomenon, scleroderma, and Raynaud phenomenon with scleroderma cohorts consisted of 161,300, 117,564, and 25,096 patients, respectively. A diagnosis of both Raynaud phenomenon and scleroderma increased the odds of upper extremity amputation by 5.4-fold, vascular procedure by 4.8-fold, and amputation within 5 years of a vascular procedure by 1.5-fold. Patients with Raynaud phenomenon or scleroderma alone were 3.1 and 5.6 times less likely to undergo amputation within 5 years of a vascular procedure, respectively.

CONCLUSIONS

Patients with both Raynaud phenomenon and scleroderma have higher likelihoods of having upper extremity amputations, vascular procedures, and amputations following vascular procedures compared to each diagnosis alone. Vascular procedures are rarely being performed. Further research is necessary to establish a standard of care and determine whether early and more frequent intervention with vascular procedures can decrease amputation rates in this patient population.

Long-term results of ulnar and radial reconstruction with interpositional grafting using the deep inferior epigastric artery for chronic hand ischemia

Chronic hand ischemia causes cold intolerance, intractable pain, and digital ulceration. If ischemic symptoms persist despite pharmacologic treatments, surgical interventions should be considered. This retrospective study evaluated the long-term results after ulnar and radial reconstruction using an interpositional deep inferior epigastric artery (DIEA) graft combined with periarterial sympathectomy. Patients who underwent this surgery from March 2003 to February 2019 were included. To evaluate variables influencing recurrence after the procedure, patients were divided into the recurred and non-recurred groups and their data were compared. Overall, 62 cases involving 47 patients were analyzed (16 and 46 cases in the recurred and non-recurred groups, respectively). The median DIEA graft length was 8.5 cm. The rates of rheumatic disease and female patients were significantly higher in the recurred than in the non-recurred group, without significant between-group differences in postoperative complication rates. In the multivariate analysis, underlying rheumatic disease and graft length had significant effects on recurrence. In Kaplan-Meier analysis, the 5- and 10-year symptom-free rates were 81.3% and 68.0%, respectively, with lower rates for cases with rheumatic disease. Thus, arterial reconstruction using an interpositional DIEA graft provides long-term sustainable vascular supply in patients with chronic hand ischemia, especially in those without rheumatic disease.

Scleroderma of the Hand: Evaluation and Treatment

Scleroderma is derived from Latin meaning hard skin. It is an uncommon, noninflammatory connective tissue disorder characterized by increased fibrosis of the skin and in certain variants, multiple other organ systems. Scleroderma involves a spectrum of pathologic changes and anatomic involvement. It can be divided into localized and systemic scleroderma. Hand involvement is common and can include calcium deposits within the soft tissues, digital ischemia, and joint contracture. Nonsurgical management consists of lifestyle modifications, biofeedback, therapy for digital stiffness/contracture, and various pharmacologic medications. When nonsurgical measures are unsuccessful, certain surgical options may be indicated, each with their inherent advantages and pitfalls. Patients with scleroderma who are undergoing surgical intervention pose unique difficulties because of their poorly vascularized tissue and deficient soft-tissue envelopes, thus increasing their susceptibility to wound healing complications and infection. Some subgroups of patients are frequently systemically ill, and specific perioperative measures should be considered to reduce their surgical risk. The spectrum of hand manifestations seen in patients with scleroderma will be reviewed with the focus on evaluation and management.

Wound, pressure ulcer and burn guidelines - 4: Guidelines for the management of connective tissue disease/vasculitis-associated skin ulcers

The Japanese Dermatological Association prepared guidelines focused on the treatment of skin ulcers associated with connective tissue disease/vasculitis practical in clinical settings of dermatological care. Skin ulcers associated with connective tissue diseases or vasculitis occur on the background of a wide variety of diseases including, typically, systemic sclerosis but also systemic lupus erythematosus (SLE), dermatomyositis, rheumatoid arthritis (RA), various vasculitides and antiphospholipid antibody syndrome (APS). Therefore, in preparing the present guidelines, we considered diagnostic/therapeutic approaches appropriate for each of these disorders to be necessary and developed algorithms and clinical questions for systemic sclerosis, SLE, dermatomyositis, RA, vasculitis and APS.

Upper Extremity Angiographic Patterns in Systemic Sclerosis: Implications for Surgical Treatment

PURPOSE

Conventional angiography is often used in the preoperative work-up of hand surgery patients with systemic sclerosis. The goal of this study was to propose a classification system based on the pattern of arterial involvement in a series of upper extremity angiograms. The authors hypothesized that this classification system would demonstrate high inter- and intrarater reliability.

METHODS

A retrospective review of 110 upper extremity angiograms in patients with systemic sclerosis (obtained between 1996 and 2017) was performed. Images were classified into 4 types based on the patency of the radial and ulnar arteries at the wrist, and into 3 subtypes based on the patency of the superficial and deep palmar arches. Classification reliability was compared with Fleiss' Kappa (for inter-rater) and Cohen's (for intrarater) coefficient between 4 fellowship-trained hand surgeons and a hand fellow.

RESULTS

The inter-rater reliability between all 5 observers using types alone was 0.83 (0.80-0.85), whereas the inter-rater reliability using subtypes was 0.64 (confidence interval [CI] 95%, 0.62-0.65). The intrarater reliability using types alone ranged from 0.80 to 0.95, whereas intrarater reliabilities using subtypes were 0.81 (CI 95%, 0.72-0.90), 0.78 (CI 95%, 0.69-0.87), 0.87 (CI 95%, 0.80-0.95), 0.64 (CI 95%, 0.53-0.75), and 0.92 (CI 95%, 0.86-0.98) for the 4 attendings and a hand fellow, respectively. Fifty-seven percent of angiograms were interpreted as having loss of ulnar artery patency at the wrist (type 2) with 77% having additional loss of superficial palmar arch patency (type 2A).

CONCLUSIONS

This large series of angiograms in patients with systemic sclerosis demonstrates a classification system for conventional angiography that shows high inter-rater and intrarater reliability using type alone. When subtypes were used, the inter-rater and intrarater reliabilities decreased to moderate and moderate-to-high, respectively.

CLINICAL RELEVANCE

This study represents the first step in establishing a classification system that, by grouping patients with similar angiogram findings, may allow for targeted research into risk stratification, monitoring, and treatment in systemic sclerosis.

Microvascular Hand Surgery for Digital Ischemia in Scleroderma

Periarterial sympathectomy and arterial bypass are microsurgical techniques which the literature suggests can provide improvement in digital pain and ulceration in patients with systemic sclerosis (SSc) who have persistent symptoms despite medication management. This review summarizes the relevant anatomy, medical therapies, operative techniques, and surgical outcomes and complications associated with the management of the vascular manifestations of SSc in the hand. Multidisciplinary collaboration between dermatology, rheumatology, and hand surgery can facilitate optimal medical and surgical management for SSc patients.

Hand and wrist joint procedures in patients with scleroderma: a systematic review

We aimed to examine if joint procedures in hands and wrists of patients with scleroderma could be performed without major morbidity and conducted a systematic review of the literature to assess this hypothesis. Studies were identified in four different databases; soft tissue procedures in scleroderma patients were excluded, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Seven studies out of an initial total of 203 articles were included. One-hundred and twelve scleroderma patients with a total of 402 joint procedures in the hand and wrist were identified. A low complication incidence, comparable with that of non-sclerodermic population, in terms of infection, wound healing problems, and nonunion was reported in all studies. The application of joint procedures in scleroderma hands and wrists seems to be associated with low morbidity.

Extended Periarterial Sympathectomy: Evaluation of Long-term Outcomes

BACKGROUND

Periarterial sympathectomy is a proposed surgical treatment for patients with refractory Raynaud syndrome; however, there is debate regarding the indications and extent of dissection. Due to the segmental arterial sympathetic innervation, we favor an extended sympathectomy in concert with vein graft reconstruction of occluded vessels when necessary. The purpose of this study is to examine outcomes of extended periarterial sympathectomy in our patients.

METHODS

A retrospective chart review was performed on 46 patients who underwent 58 periarterial sympathectomies (12 bilateral) since 1981. The data collected include demographics, comorbidities, previous therapy, operative details, and surgical outcomes. In addition, we contacted available patients for a phone survey.

RESULTS

Of 58 cases, 68.9% were female, 29.3% were current smokers, and 58.6% had known connective tissue disease. Thirty-three vein graft reconstructions were performed with a long-term patency of 77.4%. Sustained improvement of ischemic pain was reported in 94.8% of cases, and 78% of patients with ulcers completely healed. For the most symptomatic fingertip, mean Semmes-Weinstein monofilament measurements improved from 4.15 preoperatively to 3.29 postoperatively ( P ≤ .05). Mean follow-up was 3.97 years. Of 10 patients contacted by telephone, all reported a decrease in frequency and severity of Raynaud attacks, while 9 reported a long-term decrease in pain an average of 11.6 years after surgery.

CONCLUSIONS

Extended periarterial sympathectomy is an effective and safe procedure for patients with refractory Raynaud syndrome. Our data demonstrate long-term improvement in ischemic pain and sensibility, along with a high rate of ulcer healing and patient satisfaction.

Articular Surgery of the Ischemic Hand in Systemic Scleroderma: A Vascular Basis for Arthrodesis and Arthroplasty

Hallmark deformities of systemic scleroderma are early onset and progressively disabling flexion contractures of the proximal interphalangeal (PIP) joints often in conjunction with extension or, less frequently, flexion contractures of the metacarpophalangeal (MCP) joints. Although surgical correction is generally recommended, a prevailing reluctance for operative treatment exists owing to the inherent ischemia of the disease with its potentially compromised healing capacity. Nonetheless, with recognition and preservation of the tenuous but well-defined and constant periarticular vascular networks of the PIP and MCP joints, articular reconstruction with uncomplicated wound healing can prove consistently successful for patients with scleroderma. This article describes the authors' preferred methods of PIP arthrodesis vascularized by the dorsal cutaneous arterial network and MCP silicone implant arthroplasty perfused by the dorsal metacarpal arterial plexus.

Calcinosis of the Hand in Scleroderma: A Case Report

Calcinosis associated with scleroderma is a well recognized phenomenon. Fifteen to 44% of patients with systemic scleroderma and associated CREST (calcifications, raynaud's phenomenon, esophageal motility disorder, sclerodactyly and telangiectasias) syndrome have deposition of calcium in the fingers and hands. The tumourous effect may limit motion, cause neuropraxia, compound microangiopathy or present as calcific ulcers. This report describes the case of a patient with scleroderma and CREST syndrome in whom calcinosis in the hand resulted in severe, debilitating pain necessitating surgical evacuation of the deposits. The patient had complete pain relief in the postopertive period. A further surgical extirpation of calcium was required for recurring pain at six months after surgery. The patient has remained symptom free since that time. The rare occurence of excruciating pain prompted this report and literature review.

Surgery of the Hand in Severe Systemic Sclerosis

Ten patients with scleroderma and severe hand problems required surgery, and seven were available for follow-up (two died from scleroderma-related complications and one was lost to follow-up). The mean duration of follow-up was 4 (range 1.5–9) years. Thirty-three procedures were carried out, including five metacarpophalangeal joint exisional arthroplasties, 13 proximal interphalangeal joint fusions, ten distal interphalangeal joint fusions, and one thumb interphalangeal joint fusion. The metacarpophalangeal joint excision arthroplasties and proximal interphalangeal joint fusions were performed for the correction of severe fixed “finger-in-palm” deformities. Lesions of cutaneous calcinosis were removed in four patients.

Fixation was satisfactory in all cases of interphalangeal joint fusion, with no cases of non-union. Wound healing was satisfactory in six of seven patients. A second surgical procedure was required in three patients for the removal of tension band wires following interphalangeal fusion. Calcinosis was effectively removed using a high-speed dental burr. The results of hand surgery for systemic sclerosis are reliable, but goals must be limited and patient expectations should be modest.

Assessment and Surgical Treatment of Calcinosis of the Shoulder Associated with CREST Syndrome

We report an unusual case of a 65-year-old lady with CREST syndrome with multiple upper and lower limb calcinosis, who presented with severe shoulder pain and stiffness, with widespread intra- and extra-articular calcinosis, which was refractory to conservative measures. We were able to identify the main cause of her symptoms through serial diagnostic injections as calcific biceps tendinosis. We will discuss her assessment and surgical management and the pathophysiology and various treatment modalities for managing the soft tissue calcinosis in rheumatological diseases.

The wound/burn guidelines - 4: Guidelines for the management of skin ulcers associated with connective tissue disease/vasculitis

The Japanese Dermatological Association prepared guidelines focused on the treatment of skin ulcers associated with connective tissue disease/vasculitis practical in clinical settings of dermatological care. Skin ulcers associated with connective tissue diseases or vasculitis occur on the background of a wide variety of diseases including, typically, systemic sclerosis but also systemic lupus erythematosus (SLE), dermatomyositis, rheumatoid arthritis (RA), various vasculitides and antiphospholipid antibody syndrome (APS). Therefore, in preparing the present guidelines, we considered diagnostic/therapeutic approaches appropriate for each of these disorders to be necessary and developed algorithms and clinical questions for systemic sclerosis, SLE, dermatomyositis, RA, vasculitis and APS.

Nonrheumatoid Inflammatory Arthroses of the Hand and Wrist

Various inflammatory and autoimmune conditions affecting joints of the hand and wrist can present with symptoms similar to those of rheumatoid arthritis. The most common of these nonrheumatoid arthroses are psoriatic arthritis, systemic lupus erythematosus, and systemic sclerosis. Management of these and several other conditions is typically medical in nature and continues to evolve with the development of biologically targeted medications. Surgical treatment is not frequently used but can be efficacious for severe cases to alleviate symptoms and correct deformities.

Role and rationale for extended periarterial sympathectomy in the management of severe Raynaud syndrome: techniques and results

There is no consensus regarding etiology or best surgical technique for severe Raynaud syndrome in patients with connective tissue disease. Observations after 30 years' experience in more than 100 cases led to the conclusion that an extended periarterial sympathectomy (with or without vein-graft reconstruction) and adjunctive use of Botox topically will offer benefits that exceed palliation and reduce recurrent ulcerations. In this article the rationale for this approach is reviewed, techniques and results are outlined, and a hypothesis for the mechanism of Raynaud attacks is offered.

Connective tissue disorders associated with vasculitis and vaso-occlusive disease of the hand

Hand ischemia caused by vasculitis is a secondary finding in many autoimmune processes. Many of these autoimmune diseases are managed primarily with medications that can prevent the development of occlusive disease, tissue ischemia, and tissue loss. Unfortunately several disease conditions can be recalcitrant to medical management and can result in ischemic changes within the hand, which may require operative intervention. This article briefly reviews the major connective tissue disorders associated with vasculitis and vaso-occlusive disease of the hand, including scleroderma, lupus, and Buerger disease, and their surgical treatment.

High-speed burr debulking of digital calcinosis cutis in scleroderma patients

PURPOSE

To evaluate the functional outcome after removal of digital calcinosis cutis in patients with scleroderma using a high-speed burr.

METHODS

A retrospective analysis was performed of 9 consecutively enrolled scleroderma patients who underwent surgery by the senior author. A debulking procedure using a high-speed micro-burr to soften and express calcific material in digits was performed. Demographics, complications, recurrence, and postoperative functional outcome measurements including the Disabilities of the Arm, Shoulder, and Hand questionnaire, the Michigan Hand Questionnaire, a study-specific questionnaire, a visual analog scale, and the Short Form-12 were collected.

RESULTS

Mean follow-up time was 2 years. Four of 9 patients were very or somewhat satisfied with the procedure. Eight complications were recorded in 6 patients, including weakness, decreased motion, numbness, and superficial wound infection. The mean Disabilities of the Arm, Shoulder, and Hand score in patients who would have surgery again was 27 (4 of 9), versus 54 (5 of 9) for those who would not. Two patients had no recurrence. There were 7 cases of recurrence; 3 patients had late recurrence to a small degree, 3 had early complete recurrence, and 1 had recurrence at an unknown onset. No patient reported complete resolution of calcinosis. Patient satisfaction appeared inversely correlated to the number of digits involved.

CONCLUSIONS

Patients with discrete areas of calcinosis cutis, including those with 1 or 2 digits affected, did much better than patients with diffuse disease and multiple affected digits. Patients should be counseled that the benefit might be more limited than previously reported, and recurrence is likely.

Surgical management of digital calcinosis in CREST syndrome

As a limited form of sclerodermy, CREST syndrome is characterized by calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia, which determine the acronym CREST. Calcinosis is a particularly difficult entity to treat given the paucity of effective options described in the literature. Treatment of finger calcinosis has a wide range of possibilities depending on the extent of calcifications and the involvement of deep structures. From a surgical point of view, whereas simple removal is adequate in minor outpatient cases, a radical debridement in the major and more painful cases seems required. A cover flap is needed particularly in the thumb due to its great functional importance, also if the fingertip is not involved. The authors recommend the kite flap for the dimensions, the tissue quality, and the possibility of giving sensation to the reconstructed area. With this surgical option, the transferred skin is soft, sensate, and the right fit. Usually, no further operations are needed for flap remodeling. The time required for sensory integration is about 2 years, often related to the age of the patient. Debridement and flap reconstruction usually give total resolution of pain, with complete recovery of thumb motion and the thumb-index finger grip.

[Critical limb ischemia in systemic sclerosis]

Vascular complications are common in systemic sclerosis (SSc). Critical limb ischemia leading to gangrene or amputation occurs in more than 10% of these patients and hence is a common emergency. This report highlights the different pathogenetic mechanisms leading to critical ischemic events and provides guidance for the diagnosis and therapy. Apart from SSc-associated vasculopathy and peripheral arterial disease, thromboembolic events and rarely also vasculitis may cause critical limb ischemia. An interdisciplinary approach to the diagnosis and therapy of these lesions is mandatory. Therapy goals are the prevention of further ischemia and, if possible, revascularization as well as optimal pain management.

Intrinsic contractures of the thumb

A wide range of conditions can lead to intrinsic contractures of the thumb. A thorough understanding of the normal and pathologic anatomy as well as the disease processes and their effect on thumb function is essential in understanding and treating these contractures. Because intrinsic contractures of the thumb rarely present in isolation, a patient-specific approach based on functional needs is required. Prevention of iatrogenic contractures and progression of predictable contractures regardless of etiology is the health care provider's primary responsibility.

The role of regional and neuroaxial anesthesia in patients with systemic sclerosis

Systemic sclerosis (SSc), previously known as progressive systemic sclerosis, is a form of scleroderma and a multisystem connective tissue disease which can impact on every aspect of anesthetic care, especially airway management. In this review we outline clinical manifestations and current medical treatment of the disease, and general principles of anesthetizing these patients. We focus on the role of regional anesthesia, including neuroaxial anesthesia, which may serve as a safe alternative to general anesthesia but can be technically challenging. We address concerns regarding abnormal responses to local anesthesia which have previously been reported in patients with SSc, and explore future developments in technology and pharmacology, which may enable regional anesthesia to be performed more successfully and with fewer complications.

Sonographically guided hydrodissection and corticosteroid injection for scleroderma hand

Scleroderma is associated with intractable hand pain from vasospasm, digital ischemia, tenosynovitis, and nerve entrapment. This study investigated the effect of hydrodissection of the carpal tunnel followed by corticosteroid injection for the painful scleroderma hand. Twenty-six consecutive subjects [12 with painful scleroderma hand and 14 with rheumatoid arthritis and carpal tunnel syndrome (RA/CTS)] underwent sonographically observed carpal tunnel hydrodissection with 3 ml of 1% lidocaine administered with a 25-gauge 1-in. needle on a 3-ml RPD mechanical syringe (reciprocating procedure device). After hydrodissection, a syringe exchange was performed, and 80 mg of triamcinolone acetonide was injected. Baseline pain, procedural pain, pain at outcome, responders, therapeutic duration, and reinjection interval were determined. Hydrodissection and injection with corticosteroid significantly reduced pain scores by 67% in scleroderma (p < 0.001) and by 47% in RA/CT (p < 0.001). Scleroderma and RA/CTS were similar in outcome measures: injection pain (p = 0.47), pain scores at outcome (p = 0.13), responders (scleroderma, 83.3%; RA/CTS, 57.1%, p = 0.15), pain at 6 months (p = 0.15), and therapeutic duration (p = 0.07). Scleroderma patients responded better in time to next injection (scleroderma, 8.5 ± 3.0 months; RA/CTS, 5.2 ± 3.1 months, p = 0.03). Reduced Raynaud's attacks and healing of digital ulcers occurred in 83% of subjects. There were no complications. Hydrodissection with lidocaine followed by injection of triamcinolone reduces pain and vasomotor changes in the scleroderma hand. The mechanism may be a combination of hydrodissection-mediated mechanical freeing of entrapped arteries, nerves, and tendinous structures and corticosteroid-induced reduction of inflammatory vasospasm.

Long-term results of periarterial sympathectomy

PURPOSE

To compare long-term results (minimum follow-up of 23 months) of periarterial sympathectomy for patients with digital vasospasm secondary to either an autoimmune disease or generalized atherosclerotic disease. Patients with posttraumatic or localized occlusive disease and vasospasm were not evaluated.

METHODS

Twenty-eight patients had periarterial sympathectomy at 1 hospital by 1 senior surgeon. Periarterial sympathectomy was targeted to the areas of ulceration. Twenty patients (with 24 involved extremities and 42 ulcerated digits) had a documented autoimmune disease; 17 patients had scleroderma or an undifferentiated mixed connective tissue disorder, 2 had systemic lupus erythematosus, and 1 had rheumatoid arthritis. Eight patients (with 9 involved extremities and 17 ulcerated digits) had atherosclerotic disease. The primary outcomes were complete healing of all ulcers, a decrease in the number of ulcers, and need for amputation by the end of follow-up. Statistical analysis was done using the Fischer exact t-test.

RESULTS

The average follow-up for all patients was 96 months (90 months for the autoimmune group and 113 months for the atherosclerotic group). Fifteen of the 20 patients (28 of 42 digits) in the autoimmune group had complete healing or decrease in ulcer number. Conversely, only 1 of the 8 patients (2 of 17 digits) in the atherosclerotic group had complete healing or decrease in ulcer number. Eleven of the 42 (26%) digits treated in the autoimmune group required amputation. In contrast, 10 of the 17 (59%) digits treated in the atherosclerotic group ultimately required amputation.

CONCLUSIONS

Periarterial sympathectomy can lead to complete healing and decrease in ulcer number in autoimmune disease patients with digital ischemia from vasospasm. However, our data suggest that periarterial sympathectomy may be of little or no benefit in patients with chronic digital ischemia and vasospasm secondary to severe atherosclerotic disease.

Reconstructive hand surgery for scleroderma joint contractures

Systemic scleroderma can cause significant hand deformity and functional impairment. Surgery is often avoided due to the perceived risks of wound healing. The most common surgical procedures have been digital sympathectomy, arthrodesis or arthroplasty of the proximal interphalangeal (PIP) or both, and metacarpophalangeal (MCP) joints. We describe herein successful soft tissue hand surgery in 2 patients for treatment of scleroderma claw deformities without the use of arthrodesis or arthroplasty. At the MCP joint, the tight capsules were excised, and the collateral ligaments and volar plates were released. At the PIP joints, the volar plates were released and the tight palmar skin was released, resulting in marked improvement of joint position. Intensive hand therapy was used to maximize function. In these 2 patients with claw deformity, we found that tight volar skin was the main contributor to flexion contracture at the PIP level. In contrast, joint capsule contracture was the main contributor to hyperextension deformity at the MCP level.

Wound healing after hand surgery in patients with systemic sclerosis--a retrospective analysis of 41 operations in 19 patients

This retrospective study evaluates the results of 41 consecutive hand and forearm operations in 19 patients with systemic sclerosis performed between 1985 and 2000. The mean age of the patients was 50 (14-84) years. Twenty-seven operations were elective and 14 were acute, carried out for skin breakdown and/or skin necrosis. One minor wound healing problem occurred in the elective group. In the acute group, seven of 14 operations healed uneventfully. Four patients had necrosis/infections after surgery, which required further surgery. Two patients had repeated wound infections. Another patient only healed after he stopped smoking. In systemic sclerosis, surgery performed electively does not seem to have increased difficulty with wound healing. Even larger operations, such as wrist arthrodesis or wrist replacement, can be performed safely. In acute cases with spontaneous skin breakdown and/or necrosis and/or critically ischaemic fingers, wound healing is more precarious and several procedures may be necessary to achieve skin healing.

Peripheral Sympathectomy for Raynaud's Phenomenon: A Salvage Procedure

We retrospectively reviewed the effectiveness of peripheral sympathectomy for severe Raynaud's phenomenon. In this study, a total of 14 digits from six patients with chronic digital ischemic change were included. All patients had pain, ulcer, or gangrenous change in the affected digits and were unresponsive to pharmacologic or other nonsurgical therapies. In all cases, angiography showed multifocal arterial lesions, so microvascular reconstruction was unfeasible. Peripheral sympathectomy was performed as a salvage procedure to prevent digit amputation. The results were analyzed according to reduction of pain, healing of ulcers, and prevention of amputation. In 12 of the 14 digits, the ulcers healed and amputation was avoided. In the other two digits, the ulcers improved and progressive gangrene was limited. As a salvage procedure for Raynaud's phenomenon recalcitrant to conservative treatment, peripheral sympathectomy improves perfusion to ischemic digits and enables amputation to be avoided.

Periarterial sympathectomy in scleroderma patients: intermediate-term follow-up

The use of periarterial sympathectomy (PAS) to manage chronic digital ischemia caused by scleroderma remains controversial. The duration of efficacy of PAS in managing scleroderma symptoms was evaluated by examining microvascular physiology, health-related quality of life, and patient satisfaction. Twenty-two patients (29 hands) with scleroderma, chronic vascular insufficiency, and a history of nonhealing digital ulcers unresponsive to nonsurgical treatment were evaluated. Isolated cold stress testing and laser Doppler fluxmetry measurements were used to evaluate microvascular perfusion before surgery and after a mean follow-up period of 31 months (range, 7-108 months). Digital temperatures did not change after surgery, but microvascular perfusion had increased significantly at a mean of 31 months in 22 hands. Health-related quality-of-life data were collected at a mean of 46 months (range, 11-108 months) after surgery. Subjective improvement (fewer ulcers, faster ulcer healing, and decreased pain) was reported for 18 of 22 patients (24 of 29 hands) at a mean follow-up period of 46 months; 6 patients remained ulcer free. Follow-up of scleroderma patients after PAS documented improved microvascular perfusion as evaluated by laser Doppler fluxmetry and by variable clinical results.

Treatment of systemic sclerosis

Systemic sclerosis is an extremely variable disease in its manifestations and consequently, treatment needs to be individualized depending on the specific problems that each patient has. Limited scleroderma patients have a prolonged duration of Raynaud's phenomenon and puffy fingers before they develop any skin thickening, digital ulcers or gastrointestinal symptoms. They are likely to present with all the classic manifestations of scleroderma. Diffuse scleroderma patients have a much more acute systemic onset with marked whole hand swelling and may initially have only subtle skin thickening. A good understanding of the differences between the natural history of limited and diffuse scleroderma will enable the physician to treat present problems and anticipate future ones more effectively. One should determine which major subset and organ systems are involved before deciding on the appropriate therapy. Advances in organ-specific therapy, particularly calcium channel antagonists in Raynaud's phenomenon, proton pump inhibitors in esophageal reflux, intravenous iloprost and endothelin receptor antagonists in pulmonary hypertension, and ACE inhibitors in renal crisis, have decreased morbidity and mortality in patients with scleroderma. Studies of aggressive therapies to prevent or improve pulmonary fibrosis are in progress. Further clinical experience in wound healing, gastrointestinal malabsorption and physical therapy for loss of motion has helped patients to have a more comfortable life. In recent years, a significant number of controlled clinical trials have been performed and there has been improved understanding of the best way to perform studies and of which patients are most likely to respond to therapy. Penicillamine, methotrexate, photopheresis, relaxin, interferons, and cyclosporine have all been studied in controlled trials with variable outcomes. Although an overall remittive therapy has not yet been determined, new, potentially useful agents are being investigated.

Medical and surgical considerations in patients with vasculitis and Raynaud's syndrome

Vascular problems in the foot are certainly common when one considers only arteriosclerosis on the macrovascular scale. The primary cause of ischemia of the foot undoubtedly is primary arteriosclerosis, whether related to smoking, diabetes, renal failure, or other causes. Vasculitis and vasospasm, in their many forms, are distinctly unusual as a cause of ischemia of the foot. These entities, nonetheless, can cause significant problems from the standpoint of symptoms and even ulceration or gangrene of the foot. This article addresses the pathophysiology of vasculitis and vasospastic problems in the foot and their management.

Effects of peripheral sympathectomy on thermoregulatory vascular control in the rabbit ear

A rabbit ear model of the human digit was utilized to determine the vascular response to peripheral sympathectomy. Vascular responses were evaluated by subjecting chronically instrumented rabbits to a cold stress before and after sympathectomy surgery. The typical response to cold stress is for ear temperatures and auricular cutaneous perfusion to decrease during the cooling phase of the test and to increase toward baseline levels during the rewarming phase after cold exposure. Following peripheral sympathectomy, ear temperatures were significantly increased during both the cooling and rewarming phase of the cold stress test although overall ear perfusion and skin perfusion were not different from sham-operated rabbits. The responses observed in the rabbit ear following peripheral sympathectomy appear to mimic those noted in patients receiving digital peripheral sympathectomies for the treatment of refractory pain and ulceration. Peripheral sympathectomy may result in clinical improvements in patients because it improves both total digital and nutritional cutaneous blood flow. Peripheral sympathectomy in normal rabbit ears does not result in altered perfusion patterns with cold exposure although ear temperature is significantly higher. This pattern of changes suggests that the distribution of extremity perfusion is altered even though overall extremity perfusion and cutaneous perfusion per se are not significantly different from sham-operated controls. Complete sympathectomy was accompanied by a persistent increase in ear temperature and a dissociation between conductance and microvascular perfusion. Auricular conductance was transiently increased and then decreased to levels below preoperative control values. Microvascular perfusion is decreased immediately following amputation/replantation and thereafter increases.

Surgery in patients with systemic sclerosis of the hand

Systemic sclerosis of the hand is an uncommon form of arthritis that can cause significant functional loss in the hand. It poses serious problems for the surgeon because of the diminished circulation of the digits. The tightness of the skin and joint stiffness that are characteristic of this condition make restoration of function difficult. Calcinosis, which is common in patients with systemic sclerosis of the hand, can be treated by excision or curettage. Patients with severe deformities of the digits and thumb often require fusions to improve grasp. Joint replacements with implants are not as successful in patients with systemic sclerosis as they are in patients with rheumatoid or degenerative arthritis. There have been recent attempts to improve the circulation to the fingers by sympathectomy or by vein grafts. These techniques, however, provide only temporary improvement and do not prevent or correct the severe digital and thumb deformities associated with this disease.

The use of digital artery sympathectomy as a salvage procedure for severe ischemia of Raynaud's disease and phenomenon

We retrospectively reviewed the effectiveness of digital artery sympathectomy as a last resort to prevent amputation in severe cases of Raynaud's disease and phenomenon. Seven patients underwent digital artery sympathectomy as a salvage procedure to prevent amputation. The patients developed cold intolerance secondary to atherosclerosis or collagen vascular disease. The results were analyzed using the criteria of ulcer healing and the prevention of amputation. In 6 of the 7 patients, the digital ulcers healed and amputation was avoided.

Limited microsurgical arteriolysis for complications of digital vasospasm

Twenty-two digits in seven patients with chronic digital vasospasm were surgically treated after failed medical management. All patients complained of severe ischaemic pain. Chronic digital tip ulceration was present in seven digits and dry gangrene in one. Following surgical microarteriolysis all digital ulcers healed completely. Severe digital ischaemic pain was significantly improved in all digits and completely resolved in 19 of 22 digits.
