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

Increased rate of complications following total knee arthroplasty in patients with systemic sclerosis

PURPOSE

Outcomes after total knee arthroplasty (TKA) for patients with systemic sclerosis (SSc) are poorly documented in the literature. The purpose of this study was to evaluate SSc as a potential risk factor for increased rate of complications after TKA.

METHODS

Using the PearlDiver Mariner database, 2,002 patients with SSc undergoing primary TKA were identified and compared to matched controls of 19,892 patients without SSc. Multivariable logistic regression analyses were done for medical complications up to 90 days and surgical complications up to two years. 90-day ED-visit and inpatient readmission were also documented.

RESULTS

Compared to the matched controls, patients with SSc demonstrated higher rates of medical complications such as cerebrovascular accident (1.5% vs 0.6%, p < 0.001), myocardial infarction (1.3% vs 0.3%, p < 0.001), and sepsis (1.1% vs 0.4%, p < 0.001). Additionally, patients with SSc displayed elevated rates of surgical complications, including wound complications (3.9% vs 2.2%, p < 0.001) and aseptic loosening at 90 days (0.2% vs 0.1%; OR 3.53 [1.13-9.28]), one year (0.7% vs 0.4%; OR 1.78 [0.96-3.05]), and two years (1.4% vs 0.9%; OR 1.68 [1.10-2.45]). Patients with SSc also had higher rates of emergency department visits (21.2% vs 11.4%, p < 0.001).

CONCLUSIONS

Patients with SSc are at higher risks of postoperative complications, encompassing both medical and surgical complications. Specifically, patients with SSc have a significantly higher likelihood of experiencing wound complications, cerebrovascular accident, and myocardial infarction. It is crucial for orthopaedic surgeons and patients alike to consider the elevated risks when determining a course of TKA for patients with SSc.

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.

Perioperative management of patients with pulmonary hypertension undergoing non-cardiothoracic, non-obstetric surgery: a systematic review and expert consensus statement

BACKGROUND

The risk of complications, including death, is substantially increased in patients with pulmonary hypertension (PH) undergoing anaesthesia for surgical procedures, especially in those with pulmonary arterial hypertension (PAH) and chronic thromboembolic PH (CTEPH). Sedation also poses a risk to patients with PH. Physiological changes including tachycardia, hypotension, fluid shifts, and an increase in pulmonary vascular resistance (PH crisis) can precipitate acute right ventricular decompensation and death.

METHODS

A systematic literature review was performed of studies in patients with PH undergoing non-cardiac and non-obstetric surgery. The management of patients with PH requiring sedation for endoscopy was also reviewed. Using a framework of relevant clinical questions, we review the available evidence guiding operative risk, risk assessment, preoperative optimisation, and perioperative management, and identifying areas for future research.

RESULTS

Reported 30 day mortality after non-cardiac and non-obstetric surgery ranges between 2% and 18% in patients with PH undergoing elective procedures, and increases to 15-50% for emergency surgery, with complications and death usually relating to acute right ventricular failure. Risk factors for mortality include procedure-specific and patient-related factors, especially markers of PH severity (e.g. pulmonary haemodynamics, poor exercise performance, and right ventricular dysfunction). Most studies highlight the importance of individualised preoperative risk assessment and optimisation and advanced perioperative planning.

CONCLUSIONS

With an increasing number of patients requiring surgery in specialist and non-specialist PH centres, a systematic, evidence-based, multidisciplinary approach is required to minimise complications. Adequate risk stratification and a tailored-individualised perioperative plan is paramount.

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.

Hemiarthroplasty in a patient with severe systemic sclerosis

Systemic sclerosis (scleroderma) is a connective tissue disorder of unknown etiology. This rare, chronic, multisystem disorder encompasses a number of variations leading to focal and systemic classifications, which includes features such as skin thickening. The changes within the skin microstructure have led to numerous surgical complications. In a review of the orthopedic literature, we found no reports describing surgical outcomes or the success of skin closures in procedures related to the hip for patients with scleroderma. We present a case of a 74-year-old man with a history of scleroderma who underwent a bipolar hemiarthroplasty to repair a right transcervical femoral neck fracture. The risk factors associated with wound healing and effects of skin contractures in systemic sclerosis patients are reviewed.
