Pressure ulcers are a common and recurrent clinical condition in paraplegic patients, requiring specialized equipment and care, as well as surgical interventions in order to treat them. This is especially true whenever and infection is declared, which will delay or impair ulcer epitelization. These surgical interventions require a good use of various myocutaneos flaps to cover all defects. Problem arises whenever there is not enough flap tissue to cover the entire ulcer, or when multiple surgeries to correct previous ulcers have already been performed.

Our goal is to describe the use of a last resort surgical technique for covering infected pressure ulcers.

This is a retrospective and descriptive case report based on data from clinical records, patient observation and analysis of complementary exams.

We present the case of a 30-years-old man, paraplegic for 10 years due to motor vehicle accident with spinal cord injury. Since the accident, and although he used adapted equipment and pressure relief mattresses and wheelchair cushions, he developed recurrent, infected ulcers in the perineal and sacral area, being operated on for multiple times by the Plastic and Reconstructive Surgery (PRS) department, for surgical debridement and ulcer coverage with tensor faciae latae and hamstrings myocutaneous flaps.

Despite all treatment, patient developed a stage IV perineal ulcer, which ranged from his left great trochanter to the right buttock, and a simultaneous stage IV sacral ulcer. Both ulcers were infected with meticilin-resistent Staphylococcus aureus (MRSA), sensitive to vancomycin. The patient's left hip joint was also infected (due to a direct trajectory to the perineal ulcer) and subluxated (due to absence of soft tissue support).

A multidisciplinary team assembled and decision was made to disarticulate the patient's left hip, debride and irrigate extensively the surgical site, and use a double gastrocnemius myocutaneous fillet flap in-continuity, in a surgical collaboration between the Orthopaedics and PRS department. This should provide satisfactory soft tissue ulcer coverage as well as facilitate antibiotics penetrance and infection eradication.

Surgery went without complications and the patient healed uneventfully. He resumed unrestricted positioning for sitting and wheelchair mobilization. Now, at two years follow-up, the patient still has no recurrence of either the ulcer or the infection.

This surgical technique provided robust soft tissue coverage for the ulcers, as well as an important aid for infection control. It proved to be a viable option in a paraplegic patient, when more traditional flap techniques can no longer be used and with a recurrent infection.

Infection of the musculoskeletal (MSK) system is a dreaded complication that seems to be on the rise. Many factors, such as resistant bacteria or poor host factors, may influence such rise. This increase leads to greater resource consumption, especially due to antibiotic (ATB) prescription. Strategies must be created to detect patients at risk and prevent such infections. Hospital administrators should be made aware of the costs and impact of MSK infections in order to understand the need to prevent such complications.

Therefore, our goal is to characterize the infected orthopaedic patient and evaluate the cost associated with ATB prescription in such cases.

This is a retrospective and descriptive study, based on patient record analysis of all patients treated at our department, from January 2013 to March 2015.

We identified 177 patients with a MSK infection and an isolated infectious agent.

There was no predominance of either sex. Approximately 50% of patients were aged between 66 and 85 years old.

Most frequent agents were MSSA (30,2%) and MRSA (21,8%), followed by Streptococcus species (8,9%) and Pseudomonas aeruginosas (7,1%). Although most patients were infected by a single agent, 18,6% had two or more causative agents isolated in cultures. Of those, 69,7% had either MSSA or MRSA as one of the isolated agents.

Most commonly affected area was the hip (39,5%), followed by the knee (23,2%) and ankle (21,5%). Nearly all patients had had prior surgery, with arthroplasty and osteosynthesis as the most common procedures (52,4% and 33,3%, respectively).

Infection related admission was responsible for a total of 6.116 hospital bed-days, with the majority of patients staying in hospital for up to 30 days (77,3%).

Total cost of hospital ATB administration was 61.365,61€, with approximately 346,7€ spent in each patient. This corresponds to 42,6% of the total cost of medication during hospital stay (144.146,1€ of total cost, with 814,4€ per patient).

The typical infected orthopaedic patient is aged 66 to 85 years old, was operated to his hip or knee, and either an arthroplasty or osteosynthesis was performed. Staphylococcus aureus remains the most common agent.

MSK infections have significant costs associated with their treatment, and clinical departments should periodically re-evaluate discharged patients in order to understand what groups are at risk of developing such a complication.

Only a correct identification of all these factors makes it possible to create a targeted preventive strategy, in order to reduce costs to the institution.
