Intramedullary infection in long bones represents a complex clinical challenge, with an increasing incidence due to the increasing use of intramedullary fixation. We report a prospective case series using an intramedullary reaming device, the Reamer–Irrigator–Aspirator (RIA) system, in association with antibiotic cement rods for the treatment of lower limb long bone infections. A total of 24 such patients, 16 men and eight women, with a mean age of 44.5 years (17 to 75), 14 with femoral and 10 with tibial infection, were treated in a staged manner over a period of 2.5 years in a single referral centre. Of these, 21 patients had had previous surgery, usually for fixation of a fracture (seven had sustained an open fracture originally and one had undergone fasciotomies). According to the Cierny–Mader classification system, 18 patients were classified as type 1A, four as 3A (discharging sinus tract), one as type 4A and one as type 1B. Staphylococcus species were isolated in 20 patients (83.3%). Local antibiotic delivery was used in the form of impregnated cement rods in 23 patients. These were removed at a mean of 2.6 months (1 to 5). Pathogen-specific antibiotics were administered systemically for a mean of six weeks (3 to 18). At a mean follow-up of 21 months (8 to 36), 23 patients (96%) had no evidence of recurrent infection. One underwent a planned trans-tibial amputation two weeks post-operatively due to peripheral vascular disease and chronic recalcitrant osteomyelitis of the tibia and foot. The combination of RIA reaming, the administration of systemic pathogen-specific antibiotics and local delivery using impregnated cement rods proved to be a safe and efficient form of treatment in these patients.

We performed two independent, randomised, controlled trials in order to assess the potential benefits of immediate weight-bearing mobilisation after rupture of the tendo Achillis. The first trial, on operatively-treated patients showed an improved functional outcome for patients mobilised fully weight-bearing after surgical repair. Two cases of re-rupture in the treatment group suggested that careful patient selection is required as patients need to follow a structured rehabilitation regimen. The second trial, on conservatively-treated patients, provided no evidence of a functional benefit from immediate weight-bearing mobilisation. However, the practical advantages of immediate weight-bearing did not predispose the patients to a higher complication rate. In particular, there was no evidence of tendon lengthening or a higher re-rupture rate. We would advocate immediate weight-bearing mobilisation for the rehabilitation of all patients with rupture of the tendo Achillis.

The results of primary total knee replacement performed on a group of haemophiliac patients in a single institution by the same surgeon using the same surgical technique and prosthesis are reported.

A total of 35 primary replacements in 30 patients were carried out between 1996 and 2005 and were reviewed retrospectively. The mean age of the patients was 31 years (24 to 42) and the mean follow-up was for 7.5 years (1 to 10). There were 25 patients with haemophilia A and five with haemophilia B. The HIV status and CD4 count were recorded, and Knee Society scores determined. Two patients had inhibitors to the deficient coagulation factor.

There were no early wound infections and only one late deep infection which required a two-stage revision arthroplasty, with a good final result. The incidence of infection in HIV-positive and negative patients was thus similar. One knee in a patient with inhibitor had excessive bleeding due to a pseudoaneurysm which required embolisation. The results were excellent in 27 knees (77%), good in six (17%) and fair in two (6%). The survival rate at 7.5 years taking removal of the prosthesis for loosening or infection as the end-point was 97%.

The mechanical survival of total knee replacements in haemophiliacs is very good. Our results confirm that this is a reproducible procedure in haemophilia, even in HIV-positive patients with a CD4 count > 200 mm3 and those with inhibitors. Our rate of infection was lower than previously reported. This could be due to better control of the HIV status with highly active anti-retroviral therapy and the use of antibiotic-loaded cement.
