Background:

There is limited evidence regarding HIV infection as a risk factor for delayed union and implants sepsis in patient with fractures treated with surgical fixation. Most studies have included patient with a variety of different fractures and hence very different risks regarding delayed union and implant sepsis. We have looked at a single fracture, closed femoral shaft fractures treated with intramedullary nailing, to see if HIV infection is a risk factor with for the development of delayed union and implant sepsis. We present a prospective study of 160 patients with closed femoral shaft fractures treated with intramedullary nailing. Primary outcomes were delayed union of more than 6 months and implant sepsis in the first 12 months.

Methods:

From February 2011 until November 2012 all patient with closed femoral shaft fractures treated at our hospital were included in the study. Patients were tested for HIV infection and a number of clinical parameters were documented, including: AO fracture score, duration of surgery, level of training of surgeon, comorbidities, CD4 count, high energy injury and number of operations.

Background:

There are multiple risk factors regarding the outcome of open tibia fractures treated with surgical fixation. In this study we have looked at delay to debridement and HIV infection as risk factors in the outcome of open tibia fractures.

Methods:

We present a prospective study of 89 patients with open tibia fractures treated with surgical fixation with a significant delay to first debridement and a high prevalence of HIV infection.

Primary outcome of this study was time to union and wound infection in the first 3 months.

All patients admitted in our hospital between February 2011 and October 2012 with open fractures of the tibia requiring surgical fixation were included in the study. Patients were tested for HIV infection and multiple clinical parameters were documented, including; Gustilo-Anderson classification, ASEPSIS wound score, New Injury Severity Score(NISS), comorbidities, time to 1st debridement, time to 1st dose of antibiotics, pin site score, level of contamination, level training of the surgeon, high energy injuries, time to union and socio-economic parameters. Patients were followed to union.

A high volume of trauma and limited resources means that traditional methods of bone reconstruction are not feasible in parts of Africa. We present the management and outcomes of using Masquelet's concept, of an induced membrane and secondary morcellised cancellous bone grafting, in patients with severe lower limb trauma.

Eleven patients were treated in an orthopaedic department in rural southern Africa between 2011 and 2012. This is a subgroup that is part of a larger study of open fractures that received ethical approval.

All patients were male, with ten aged between 20 and 35 and one aged 70. Two were HIV positive. There were three open femur and eight open tibia fractures. Three required fasciocutaneous flaps and one required a muscle flap to achieve adequate soft tissue coverage. Eight cases were performed as the primary treatment and three were to treat septic non-unions. Bone defects ranged from 4 to 10 cm. Definitive bony stabilisation was maintained by mono-lateral external fixator in three patients. In other cases this was converted to a circular frame or internal fixation.

The results have been mixed. In three patients bone grafting was delayed due to wound or pin site problems. In one case the bone graft was lost due to infection but repeating the procedure produced a good result. Time to bony union in each case is difficult to quantify. However, there is clear evidence of new bone forming in most cases. Four patients are weight bearing with external fixation removed, as are five patients with internal fixation. In a few cases bony union appears to be taking significantly longer, if at all.

Masquelet technique is a welcome addition to the options available in bone reconstruction. However, time to achieve bony union is unpredictable. Refinement of the technique for use in the developing world is needed.

Background

In 2011 Aird et al published their results of the effects of HIV on early wound healing in open fractures treated with internal and external fixation. The study was conducted between May 2008 and March 2009 and performed in semi-rural area of KwaZulu-Natal, South Africa. These results suggested that HIV is not a contraindication to internal or external fixation of open fractures, as HIV is not a significant risk factor for acute wound implant infection. We present a longer term follow up of this same cohort of patients from the original study.

Methods

From March 2011 to January 2012 we attempted to contact all patients from Airds original study. A simple telephonic questionnaire was obtained from all the patients contacted, regarding possible late sepsis, non-union and implant removal. Patients were requested to visit the outpatient department for a clinical assessment, a repeat HIV test and new X-rays.
