Surgical treatment of distal tibia fractures is usually associated with extensive soft tissue compromise and high complication rates (infection, delayed or non-union, ankle stiffness and osteoarthritis). Wound infection is one of the most common complication (deep infection rates up to 15%) and can develop into an infected non-union.

In 1973, Papineau described a staged technique for treating infected non-union of long bones, consisting of (1) surgical debridement of necrotic tissue, temporary splinting, specific antibiotic treatment, postoperative wet-to-dry wound dressing changes; (2) packing of the bone defect with cortico-cancellous autograft; (3) closure of the soft-tissue wound by a flap or secondary intent.

The authors aim to report a clinical case of a successful treatment of a distal tibia infected non-union with the Papineau technique and negative-pressure wound therapy.

Woman, 56 years-old, referred to Orthopaedic consultation on October 2013 for wound dehiscence and infection with a methicillin-resistant Staphylococcus aureus, one month after open reduction and internal fixation of an open distal tibia fracture.

On November 2013 she underwent surgical debridement, removal of osteosynthesis material, osteotaxis with external fixator, negative-pressure wound therapy and antibiotic treatment with intravenous vancomycin 1g 12/12h (1st stage of Papineau procedure)

On December, she underwent autologous iliac crest cancellous bone grafting and wound care, daily irrigated with saline solution (2nd stage).

On February 2014, she underwent a partial thickness skin graft for wound closure (3rd stage).

On April, the external fixator was removed and there was still no evidence of union. She had pain, disuse osteoporosis, ankle and midfoot stiffness, and was sent to physical therapy.

On April 2015, she can full weight bear with mild pain, the soft tissue envelope is in good condition, the fracture has united and she has an Ankle AOFAS Score of 83.

The Papineau technique has been used for the management of infected non-unions with bony defects, with high success rates. Complete necrotic tissue debridement and targeted antibiotics are fundamental for obtaining a viable and healthy tissue, able to receive the bone graft. Negative-pressure wound therapy is important in reducing the bacterial load, improving the microcirculation and enhancing the granulation tissue.

In the present case, the combination of the two techniques probably acted together in achieving successful eradication of the infection, reconstruction of the bone defect and soft tissue closure.

Surgical Site Infection (SSI) is one of the most frequent nosocomial infections and depends on many factors: patient, microorganism, antiseptic solution use, antibiotic prophylaxis, hand scrubbing, wound care or hospital stay lenght.

With the present paper the authors aim to study the SSI incidence after Total Knee (TKA) or Hip Arthroplasty (THA).

All patients who underwent primary TKA or THA between January 2011 and May 2012 at our institution were considered. Patients who died within 1 year after the procedure of unrelated causes were excluded. Data collected included ASA classification, type of procedure, total and post-operative hospital stay, type and duration of antibiotic prophylaxis.

Data were collected from the consultation at 1 month and 1 year post-operative, clinical registries and telephone interview. SSI was defined according to the Centers for Disease Control and Prevention criteria. Suspected cases of SSI included antibiotic administration longer than 5 days or absence of antibiotic prescription, hospital stay after the procedure longer than 9 days, patient referring infection symptoms, and clinical data reports of infection or re-intervention.

During the studied period and after exclusion of 5 cases, a total of 251 surgeries (104 TKA, 147 THA) were performed, of which 2 were urgent.

For both TKA and THA, the average total hospital stay was 9 days (8 days post-operative). The majority were American Society of Anesthesiologists (ASA) classification 2 and 3.

There were 4 SSI (1,60%), 2 TKA (1,92%) and 2 THA (1,36%), all of them after discharge. Their average total hospital stay was 10,5 days.

Antibiotic prophylaxis was used in 93% of the patients (97,4% a cephalosporin), with an average length of 5,7 days.

Recommended hospital stay after a TKA or THA is about 5 days. On HELICS-CIRURGIA 2006–2010 report it was 10 days, similar to ours. In infected patients, our total hospital stay was lower (10,5 vs 26).

Recommended duration of antibiotic prophylaxis is 24h. On HELICS-CIRURGIA more than 50% had it for more than 24h, which also happened with us; our antibiotic coverage was similar.

Comparing to HELICS-CIRURGIA, the predominance of ASA 2 and 3 classifications was similar, but the overall SSI rate was lower (1,6% vs 2,24%).

We conclude we must reduce hospital stay and antibiotic duration and keep the surveillance of SSI after TKA or THA.
