A Systematic review and meta-analysis of sensate versus non-sensate flaps for the prevention of pressure ulcer recurrence among individuals with spinal cord disease

Lower-Extremity Fillet Flap for Reconstruction of Complex Stage IV Pressure Sores and Plantar Flap for Lumbosacral Padding

BACKGROUND

The lower-extremity fillet flap is a suitable option for the repair of complex (multiple or complicated with osteomyelitis) stage IV pressure sores. If prepared from a nonfunctional extremity, it can close complex wounds and avoid the unnecessary burden of a nonfunctional organ that restricts patient movement, thereby improving quality of life.

METHODS

We used a lower extremity fillet flap for reconstruction in 5 patients with complex stage IV pressure sores. The flaps were prepared from the nonfunctional lower extremity with multiple lesions by using iliofemoral disarticulation. The mean age of the patients was 60 years old, and the mean follow-up period was 18 months. A plantar flap was used in 1 patient for prophylactic padding of the lumbosacral region. In another patient, the plantar flap was used as a sensate flap.

RESULTS

No major complications, such as total or partial flap loss, occurred in these patients. In 1 patient, a hematoma developed under the flap that led to dehiscence; however, it healed uneventfully without flap loss. Patients developed minimal pelvic stability and balance loss because of iliofemoral disarticulation, but it did not affect their sitting ability and mobility. After the operation, all patients became increasingly active and mobile because of the absence of excess weight on their nonfunctional legs, allowing them to easily perform daily activities such as turning in bed, using a wheelchair, eating, and dressing. Pressure sores did not develop in any of the patients during the postoperative follow-up period. The patient who underwent lumbosacral padding with a sensate plantar flap began to perceive touch over the flap in the fifth postoperative month.

CONCLUSIONS

These results suggest that a lower-extremity fillet flap can be a good repair option in complex stage IV pressure sores because it prevents recurrence and enables patients to perform daily activities more easily. Furthermore, plantar flaps can provide prophylactic padding in the lumbosacral region.

Retrospective analysis of the management of pelvic decubitus ulcers and their outcomes

Background

Many patients with decubitus-related osteomyelitis are ineligible for myocutaneous flapping, and optimal management in this population is unknown. We describe treatments and outcomes of hospitalized patients with decubitus ulcer-related osteomyelitis who did not undergo surgical reconstruction or coverage.

Methods

We systematically identified hospitalized patients with diagnoses of pelvic, sacral, or femoral osteomyelitis due to decubitus ulceration between 1 January 2018 and 31 December 2018. Demographics, comorbidities, laboratory data, and outcomes were collected by manual chart review. T-tests or Chi-square tests were used for descriptive statistical comparisons; logistic regressions were used to explore the odds of readmission, osteomyelitis-related readmission, and death.

Results

Of 89 patients meeting inclusion criteria, 34 (38%) received surgical debridement and ⩾6 weeks of antibiotics; 55 (62%) received either antibiotics alone or debridement and <6 weeks of antibiotics. Mean age was 55 (standard deviation 18) years, 55% of patients were male, and 69% had spinal cord injury or other form of paralysis. Within 1 year, 56 (63%) patients were readmitted, 38 (44%) patients were readmitted due to complications from osteomyelitis, and 15 (17%) died. We found no significant differences in readmission (OR = 1.33, 95% CI: 0.54-3.21, p = 0.53), readmission related to osteomyelitis (OR = 1.64, 95% CI: 0.69-4.04, p = 0.27), subsequent sepsis (OR = 2.27, 95% CI: 0.83-6.93, p = 0.13), or death (OR = 2.88, 95% CI: 0.83-13.4, p = 0.12) by treatment group.

Conclusions

Among patients with decubitus-related osteomyelitis who did not undergo myocutaneous flapping, outcomes were generally poor regardless of treatment, and not significantly improved with prolonged antibiotics. Prospective studies are needed to assess best practice strategies for this challenging patient population.

Reconstructive surgery for treating pressure ulcers

BACKGROUND

There are several possible interventions for managing pressure ulcers (sometimes referred to as pressure injuries), ranging from pressure-relieving measures, such as repositioning, to reconstructive surgery. The surgical approach is usually reserved for recalcitrant wounds (where the healing process has stalled, or the wound is not responding to treatment) or wounds with full-thickness skin loss and exposure of deeper structures such as muscle fascia or bone. Reconstructive surgery commonly involves wound debridement followed by filling the wound with new tissue. Whilst this is an accepted means of ulcer management, the benefits and harms of different surgical approaches, compared with each other or with non-surgical treatments, are unclear. This is an update of a Cochrane Review published in 2016.

OBJECTIVES

To assess the effects of different types of reconstructive surgery for treating pressure ulcers (category/stage II or above), compared with no surgery or alternative reconstructive surgical approaches, in any care setting.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was January 2022.

SELECTION CRITERIA

Published or unpublished randomised controlled trials (RCTs) that assessed reconstructive surgery in the treatment of pressure ulcers.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected the studies, extracted study data, assessed the risk of bias and undertook GRADE assessments. We would have involved a third review author in case of disagreement.

MAIN RESULTS

We identified one RCT conducted in a hospital setting in the USA. It enrolled 20 participants aged between 20 and 70 years with stage IV ischial or sacral pressure ulcers (involving full-thickness skin and tissue loss). The study compared two reconstructive techniques for stage IV pressure ulcers: conventional flap surgery and cone of pressure flap surgery, in which a large portion of the flap tip is de-epithelialised and deeply inset to obliterate dead space. There were no clear data for any of our outcomes, although we extracted some information on complete wound healing, wound dehiscence, pressure ulcer recurrence and wound infection. We graded the evidence for these outcomes as very low-certainty. The study provided no data for any other outcomes.

AUTHORS' CONCLUSIONS

Currently there is very little randomised evidence on the role of reconstructive surgery in pressure ulcer management, although it is considered a priority area. More rigorous and robust research is needed to explore this intervention.

Reconstruction of recalcitrant pressure ulcers with latissimus dorsi muscle-splitting free flaps

BACKGROUND

Reconstruction of recalcitrant pressure ulcers is very challenging because all available local tissues have been exhausted. Although occasionally suggested as reconstructive options in some reports, free flaps are still not favored for pressure ulcers because of the less available recipient vessels in buttock area and the need for position change. Here, we describe our experience with latissimus dorsi muscle-splitting free flaps harvested in prone position for recalcitrant pressure ulcers.

METHODS

Between January 2012 and January 2020, 10 patients of recalcitrant pressure ulcers underwent reconstruction using latissimus dorsi muscle-splitting free flaps. To harvest flaps in the prone position, the curvilinear incision was made along the line connecting the lateral border of the scapula and the midaxillary line of the armpit and the latissimus dorsi muscle was split just below the skin incision. Only the required amount of muscle was harvested including the 5 × 3 cm sized muscle cuff around bifurcation points of the transverse and descending branches.

RESULTS

Flap size ranged from 16 × 9 to 24 × 14 cm and the gluteal vessels were mainly used as recipients. The mean operation time was 170 mins. All the flaps survived but two patients suffered wound disruption and partial flap loss, respectively. During the mean follow-up periods of 2.45 years, there were no recurrences at the reconstruction site, and no patient complained of donor site morbidity.

CONCLUSIONS

Based on the results obtained from this consecutive series of patients, latissimus dorsi muscle-splitting free flaps are valuable option for recalcitrant pressure ulcer reconstruction.
