Flap reconstruction of pressure ulcers in patients with spinal cord injury: a retrospective cohort study

STUDY DESIGN

Retrospective case series.

OBJECTIVES

To describe our five-year experience of surgical excision and flap reconstruction of pressure ulcers in individuals with spinal cord injury (SCI).

SETTING

Tertiary spinal centre in Stoke Mandeville, United Kingdom.

METHODS

All spinal injury patients that underwent surgical reconstruction of pressure ulcers at the Stoke Mandeville Hospital National Spinal Injury Centre between 2018 and 2022 inclusive were included. Ulcers underwent 'pseudotumour' excision followed by either immediate or staged flap reconstruction. The primary outcome was complete healing at one year. Secondary outcomes included flap loss, complications, and return to theatre.

RESULTS

52 cases were included across 44 patients. 43 cases (82.7%) underwent immediate debridement and reconstruction. The mean number of procedures was 1.9 (range 1-6). Local flaps were used in 22 (41.5%) cases. There was one (1.9%) free flap (anterolateral thigh), eight (15.4%) pedicled flaps, and 21 (39.6%) flaps based on single perforators. 49 cases completed follow-up; 41 (83.7%) were healed at one year after their initial surgery. Immediate reconstructions were 36.7% more likely to achieve healing at this time point than staged cases (P = .028, Fisher's exact). There was partial or total flap loss in 15 (28.8%) cases. Thirty-nine complications were seen in 24 (46.2%) cases. Twenty-three cases (44.2%) required returns to theatre.

CONCLUSIONS

Surgical debridement with flap reconstruction is a safe and reliable treatment approach for pressure ulcers in those with SCI, with a complication rate comparable to existing literature. Immediate flap reconstruction and local flap designs may be associated with a lower risk of complications and higher healing rates.

Pressure ulcer prevention: family caregiver training effectiveness

OBJECTIVE

To determine the effectiveness of pressure ulcer prevention training for the relatives of palliative care inpatients.

METHODS

This study had a pretest-post-test design with parallel groups and a randomised control group, and it was conducted with 70 (experimental n=35, control n=35) patient relatives. A personal information form and Pressure Ulcer Knowledge Test were used as data collection tools. Parametric tests were performed for statistical analysis.

RESULTS

The pressure ulcer prevention training given to the relatives of palliative care patients in the experimental group was significantly effective in increasing their level of knowledge about these ulcers (p<0.05). However, the routine ward discharge training given to the relatives of palliative care patients in the control group was not significantly effective in increasing their level of knowledge about them (p>0.05).

CONCLUSIONS

Specialised training regarding pressure ulcers should be given to the relatives of patients receiving palliative care. It is important that the educational materials used in this trainings appeal to all sensory organs in order to improve the educational outcomes.

Osteomyelitis in Late-Stage Pressure Sore Patients: A Retrospective Analysis

BACKGROUND

Late-stage pressure sore (PS) patients are particularly susceptible to osteomyelitis (OM), as bony prominences commonly constitute the focal point of the ulcer. There are lack of data regarding the associated factors and the clinical relevance of this diagnosis in the context of PS treatment.

METHODS

This retrospective analysis investigated the clinical characteristics, blood markers indicative of infection in PS patients, and development of histologically evident OM. A total of 125 patient were included from 2014 to 2019. The patient records were especially scanned for histological diagnosis of OM.

RESULTS

OM was detected in 39% (37/96) of the samples taken during the index procedure. OM prevalence increased to 56% (43/77) at the second and 70% (41/59) at the third debridement. Therefore, the diagnosis of OM was acquired during treatment in 35 cases. Patients diagnosed with initial OM presented significantly higher blood markers, indicative of infection upon admission. Only patients with consistent OM (three positive biopsies) showed higher flap revision rates.

CONCLUSION

This study found no compelling evidence linking OM to worse clinical outcomes in PS patients. In the absence of elevated inflammatory markers, reducing bone biopsy frequency and adopting a less aggressive bone debridement approach may help prevent OM in PS patients.

Negative Pressure Wound Therapy for Chronic Wounds

ABSTRACT

Chronic wounds, including those caused by venous and arterial insufficiency, diabetic complications, and pressure-induced ulcers, pose significant treatment challenges. Negative pressure wound therapy has been increasingly used for managing these wounds. This treatment aims to promote wound healing, prepare the wound bed for further surgical intervention, minimize the risk of infection, and potentially shorten the time to wound healing. Considering variances in techniques applied in different regions globally, there is an emerging need to comprehensively evaluate the effectiveness of negative pressure wound therapy on chronic wounds. Unfortunately, detailed descriptions of the techniques applied to achieve negative pressure are often lacking in existing literature abstracts, posing challenges for direct comparisons. This review aims to analyze the application of negative pressure wound therapy in the treatment of chronic wounds, summarize its advantages and disadvantages, and further explore the potential value and future research direction of negative pressure wound therapy in the repair of chronic wounds.

Management of deep sacral and ischial pressure injuries with free-style local perforator flaps: A D+P+DPD model

BACKGROUND

Previous reports on the treatment of sacral and ischial pressure injuries have not provided clear algorithms for surgical therapies. The objective of this study was to establish a reconstruction algorithm to guide the selection of an ideal free-style perforator flap that can be tailored to the defect in question.

METHODS

We used 23 perforator flaps to reconstruct 14 sacral and 8 ischial defects in 22 patients over 5 years. A reconstruction algorithm system was developed based on the anatomical features of the perforator vessels (diameter, D; pulsatility [++∼+++], P) and their position in the skin island (DPD) (ie, D+P+DPD). A perforator-based propeller flap was applied as the first-line choice; if this plan was not feasible, we applied an altered V-Y advancement model or another second-choice technique.

RESULTS

All flaps survived, and only 1 patient experienced partial wound dehiscence, which healed by secondary intention. After an average follow-up period of 11.2 months, no patient experienced recurrence or infection.

CONCLUSIONS

Free-style perforator flap selection is determined by pressure injury and the desired advantage of a specific approach. The use of free-style perforator-based propeller flaps allows a surgeon to transfer healthy tissue into the defect, shifts the suture line away from the bony prominence, and preserves additional future donor sites. In cases where unexpected variations are encountered, the V-Y advancement model or another technique can be used. The simplified surgical algorithm (D+P+DPD) can provide versatility and reliability, achieve a durable, natural esthetic outcome, and minimize injuries to future donor sites.

Improving the Care and Cost of Treating Community-Acquired Stage 3 and 4 Decubitus Ulcers

INTRODUCTION

The healthcare costs for treatment of community-acquired decubitus ulcers accounts for $11.6 billion in the United States annually. Patients with stage 3 and 4 decubitus ulcers are often treated inefficiently prior to reconstructive surgery while physicians attempt to optimize their condition (debridement, fecal/urinary diversion, physical therapy, nutrition, and obtaining durable medical goods). We hypothesized that hospital costs for inpatient optimization of decubitus ulcers would significantly differ from outpatient optimization costs, resulting in significant financial losses to the hospital and that transitioning optimization to an outpatient setting could reduce both total and hospital expenditures. In this study, we analyzed and compared the financial expenditures of optimizing patients with decubitus ulcers in an inpatient setting versus maximizing outpatient utilization of resources prior to reconstruction.

METHODS

Encounters of patients with stage 3 or 4 decubitus ulcers over a 5-year period were investigated. These encounters were divided into two groups: Group 1 included patients who were optimized totally inpatient prior to reconstructive surgery; group 2 included patients who were mostly optimized in an outpatient setting and this encounter was a planned admission for their reconstructive surgery. Demographics, comorbidities, paralysis status, and insurance carriers were collected for all patients. Financial charges and reimbursements were compared among the groups.

RESULTS

Forty-five encounters met criteria for inclusion. Group 1's average hospital charges were $500,917, while group 2's charges were $134,419. The cost of outpatient therapeutic items for patient optimization prior to wound closure was estimated to be $10,202 monthly. When including an additional debridement admission for group 2 patients (average of $108,031), the maximal charges for total care was $252,652, and hospital reimbursements were similar between group 1 and group 2 ($65,401 vs $50,860 respectively).

CONCLUSIONS

The data derived from this investigation strongly suggests that optimizing patients in an outpatient setting prior to decubitus wound closure versus managing the patients totally on an inpatient basis will significantly reduce hospital charges, and hence costs, while minimally affecting reimbursements to the hospital.

Measurement of combined flap thickness for reconstruction of decubitus ulcer using computed tomography

BACKGROUND

Various reconstruction options have been introduced to treat decubitus ulcers. A combined flap that takes advantage of the fasciocutaneous and muscle flaps has been proven to be effective in reconstructing decubitus ulcers in previous studies. However, no studies have measured combined flap thickness. This is the first study to demonstrate the superiority of the combined flap by measuring its thickness using enhanced abdominopelvic computed tomography (APCT).

AIM

To evaluate combined flap modality as a useful reconstruction option for decubitus ulcers using measurements obtained through APCT.

METHODS

Fifteen patients with paraplegia who underwent combined flap surgery for reconstruction of decubitus ulcers between March 2020 and December 2021 were included. The defects in the skin and muscle components were reconstructed separately. The inner gluteus muscle flap was split and manipulated to obliterate dead space. The outer fasciocutaneous flap was transposed to cover the muscle flap and opening of the decubitus ulcer. Subsequently, we performed enhanced APCT at 3 wk and 6 mo postoperatively to measure the flap thickness.

RESULTS

The mean flap thickness was 32.85 ± 8.89 mm at 3 wk postoperatively and 29.27 ± 8.22 mm at 6 mo postoperatively. The flap thickness was maintained without any major complications such as contour deformities or recurrence.

CONCLUSION

Although there was a significant decrease in flap thickness as measured by APCT, the combined flap provided sufficient padding and maintained its thickness even at 6 mo after reconstruction, suggesting that the combined flap modality may be a useful reconstruction option for patients with paraplegic decubitus ulcers.

Determinants of the success in flap reconstruction-Outcome analysis of 120 flaps in 484 procedures for pressure injury

Pressure injury (PI) mainly occurs in bedridden older adults or those with physical limitations. Here, we aimed to determine the appropriate timing to conduct flap reconstruction in patients with PIs and identify factors affecting surgical outcomes. We retrospectively reviewed the data of all patients who received debridement or flap reconstruction surgery for PIs in our hospital from January 2016 to December 2021. The extracted data included patient demographics, surgical records, blood test results, vital signs, and flap outcomes. In total, 484 surgical procedures (364 debridements and 120 flaps) were performed on 216 patients. Serum albumin level of ≥2.5 g/dL remarkably increased the likelihood of complete wound healing (odds ratio [OR] = 4.12, P = .032) and reduced the risk of postoperative complications (OR = 0.26, P = .040). In contrast, advanced age (OR = 1.04, P = .045) and serum creatinine level ≥2 mg/dL (OR = 5.07, P = .016) increased the risk of postoperative complications. Thus, patients with a favourable nutrition status have a higher likelihood of achieving complete wound healing. By contrast, patients who are older and have serum creatinine ≥2 mg/dL and serum albumin <2.5 g/dL tend to develop more postoperative complications. Overall, thorough correction for patient inflammation, infection, anaemia, and malnutrition status can provide optimal flap surgery outcomes.

Application of the Jigsaw Puzzle Flap Based on Freestyle Perforators to Repair Large and Deep Ulcers on the Buttocks

Background

Decubitus ulcers are common skin injuries in plastic and burn surgery departments, usually occur in patients with a long disease course and poor underlying health. Designing a reconstruction procedure with safety blood supply to a large volume soft tissue and resulting in minimal trauma is a priority for surgeons.

Methods

The free-style perforators on the potential donor sites surrounding the ulcers were detected by Doppler, and the area of the ulcer was divided into several sections based on the location of pre-design perforator flaps. According to the insertion point of the perforators, small V-Y advancement flaps, propeller flaps and rotation flaps pedicled with freestyle perforators were formed and moderately modified during surgery. All of the small flaps were transplanted from donor sites to the defect and reassembled into a new composite flap to repair the ulcer. The donor sites were directly closed. The area of the flaps ranged from 7.0 × 10.5 cm to 8.0 × 22.0 cm and the diameter of the pedicle perforators ranged from 0.5 to 4.0 mm.

Results

In 30 patients, 65 flaps were constructed, and all of the flaps survived with direct closure of all donor sites. One case with effusion healed 1 month postoperatively through draining and application of a mild pressure dressing. After a 3–24 months follow-up period, all of the patients were satisfied with post-operative function and appearance, and only one case had a local recurrence 6 months postoperatively.

Conclusion

The jigsaw puzzle flap based on freestyle perforators can repair the large skin and soft tissue defects caused by decubitus ulcers on the buttocks, with direct donor flap area closure. This method is easy to perform with a safe blood supply and minimal trauma resulting from the avoidance of microvascular anastomosis and the conventional myocutaneous flap.
