ABSTRACT

PURPOSE: Infected orthopaedic metalwork is challenging to treat. Negative pressure wound therapy (NPWT) with irrigation is an emerging therapy for infected wounds as an adjunct to antibiotic therapy. The senior author had devised a modified technique to augment its efficacy, utilising high-flow rate irrigation and skin closure over the standard NPWT dressing. This novel technique was originally evaluated in a different centre and produced 100% success in metalwork retention. The present study is a reproducibility test of the same technique. METHODS: A retrospective review was performed on 24 patients with infected orthopaedic metalwork, including 3 upper limb and 21 lower limb cases, for outcomes relating to implant retention and infection resolution. Patients underwent a modified NPWT technique as an adjunct to antibiotic therapy and surgical debridement. Detailed medical and microbiology information were obtained from the patient records. RESULTS: 23 of 24 (96%) patients had successful metalwork retainment with healed wounds and resolution of infection, allowing fracture union. 27 infective organisms were identified in this cohort, and the antibiotic regimens for each patient are provided. The average follow-up was 663 days. No adverse effects were observed. CONCLUSION: This series supports the modified NPWT technique as a safe, reliable and effective adjunct therapy to resolve metalwork infection. The same results have been reproduced as the previous cohort in a different centre.

ABSTRACT

BACKGROUND: This study describes the outcomes of internal bone transport with magnetic nails in five cases of traumatic segmental femoral bone defects. METHODS: Five patients with open fracture of the femur and diaphyseal bone loss were included between May 2018 and August 2020. The mean femoral defect was 8.7 cm (range 5.6-16.0). INTERVENTION: We used plate-assisted bone segment transport (PABST) with PRECICE magnetic nails. RESULTS: All five patients have fully consolidated. The mean consolidation time and index were 7.5 months and 0.8 mo/cm, respectively. The mean follow-up was 21.3 months. The main complications were reduced knee ROM, mild varus deformity and plate bending. Post-operative SF-36, Oxford Knee scores and ED-5Q-5L scores were also compiled for four of five patients. SF-36 and Oxford Knee scores were reported without pre-injury data for comparison. ED-5Q-5L index and VAS were compared UK population norm and were both found to be statistically insignificant (p = 0.071 and p = 0.068, respectively). CONCLUSION: Bone transport with magnetic nails has the capacity to obtain good functional recovery in long bone defects despite variable outcome pictures. In response to variable outcome reporting in the literature, we propose a standard reporting template for future studies to facilitate more rigorous analyses.
