Aims. The aim of the present study was to assess the outcomes of the induced membrane technique (IMT) for the management of infected segmental bone defects, and to analyze predictive factors associated with unfavourable outcomes. Methods. Between May 2012 and December 2020, 203 patients with infected segmental bone defects treated with the IMT were enrolled. The digital medical records of these patients were retrospectively analyzed. Factors associated with unfavourable outcomes were identified through logistic regression analysis. Results. Among the 203 enrolled patients, infection recurred in 27 patients (13.3%) after bone grafting. The union rate was 75.9% (154 patients) after second-stage surgery without additional procedures, and final union was achieved in 173 patients (85.2%) after second-stage surgery with or without additional procedures. The mean healing time was 9.3 months (3 to 37). Multivariate logistic regression analysis of 203 patients showed that the number (≥ two) of debridements (first stage) was an independent risk factor for
Aims. The use of local antibiotic carriers in the treatment of chronic osteomyelitis is an important adjunct in dead space management. We present the outcomes of two different biodegradable antibiotic carriers used in the management of chronic osteomyelitis. Method. A single centre series between 2006–2017. The initial cohort (2006–2010) of 137 cases, Group A, had Osteoset® T (calcium sulphate carrier containing tobramycin). The second cohort (2013–1017) of 160 cases, group B, had CeramentTM G (biphasic calcium sulphate, nano-crystalline hydroxyapatite carrier containing gentamicin). Only Cierny-Mader Grade III and IV cases were included with a minimum six-month radiographic follow-up.
Musculoskeletal infection is a devastating complication in both trauma and elective orthopaedic surgeries that can result in significant morbidity. Aim of this study was to assess the effectiveness and complications of local antibiotic impregnated dissolvable synthetic calcium sulphate beads (Stimulan Rapid Cure) in the hands of different surgeons from multiple centres in surgically managed bone and joint infections. Between January 2019 and December 2022, 106 patients with bone and joint infections were treated by five surgeons in five hospitals. Surgical debridement and calcium sulphate bead insertion was performed for local elution of antibiotics in high concentration. In all, 100 patients were available for follow-up at regular intervals. Choice of antibiotic was tailor made for each patient in consultation with microbiologist based on the organism grown on culture and the sensitivity. In majority of our cases, we used a combination of vancomycin and culture sensitive heat stable antibiotic after a thorough debridement of the site. Primary wound closure was achieved in 99 patients and a split skin graft closure was done in one patient. Mean follow-up was 20 months (12 to 30).Aims
Methods
This study aimed to investigate the clinical characteristics and outcomes associated with culture-negative limb osteomyelitis patients. A total of 1,047 limb osteomyelitis patients aged 18 years or older who underwent debridement and intraoperative culture at our clinic centre from 1 January 2011 to 31 December 2020 were included. Patient characteristics, infection eradication, and complications were analyzed between culture-negative and culture-positive cohorts.Aims
Methods
Aims. To investigate a treatment algorithm of various Ilizarov methods in managing infected tibial non-union. Patients and Methods. A consecutive series of 76 patients with infected tibial non-union were treated with one of four Ilizarov protocols, consisting of; monofocal distraction (25 cases), monofocal compression (18), bifocal compression/distraction (16) and bone transport (17). Median duration of non-union was 10.5 months (range 2–546 months). All patients underwent at least one previous operation, 36 had associated limb deformity and 49 had non-viable non-unions. Twenty-six cases had a new muscle flap at the time of Ilizarov surgery and 24 others had pre-existing flaps. Results. Infection was eradicated in 74 cases (96.1%) at a mean follow-up of 42 months (range 8–131). Both
Background. Although gradual bone transport may provide a large-diameter bone, complications are common with the long duration of external fixation. To reduce such complications, a new technique of bone transport with a locking plate has been done for tibial bone defect. Methods. In 13 patients (mean age, 38.9 years) of chronic osteomyelitis or traumatic bone defect, segmental transport was done using external fixator with a locking plate. In surgical technique, a locking plate was fixed submuscularly, holding the proximal and distal segments. Then, the external fixator for transport was fixed without contact of the locking plate. After docking, 2 or 3 screws were fixed at the transported segment through the plate holes. At the same time, the external fixator was removed. Results. The mean transported amount was 5.8cm, and the mean external fixation index was 13.3 days/cm. The primary union at the docking site was achieved in all cases. No patients showed angular deformity over 5 degrees. There were 2 patients of leg length discrepancy with less than 1.5cm. Deep
Endoprosthetic replacement of the proximal femur may be required to treat primary bone tumours or destructive metastases either with impending or established pathological fracture. Modular prostheses are available off the shelf and can be adapted to most reconstructive situations for this purpose. We have assessed the clinical and functional outcome of using the METS (Stanmore Implants Worldwide) modular tumour prosthesis to reconstruct the proximal femur in 100 consecutive patients between 2001 and 2006. We compared the results with the published series for patients managed with modular and custom-made endoprosthetic replacements for the same conditions. There were 52 males and 48 females with a mean age of 56.3 years (16 to 84) and a mean follow-up of 24.6 months (0 to 60). In 65 patients the procedure was undertaken for metastases, in 25 for a primary bone tumour, and in ten for other malignant conditions. A total of 46 patients presented with a pathological fracture, and 19 presented with failed fixation of a previous pathological fracture. The overall patient survival was 63.6% at one year and 23.1% at five years, and was significantly better for patients with a primary bone tumour than for those with metastatic tumour (82.3% vs 53.3%, respectively at one year (p = 0.003)). There were six early dislocations of which five could be treated by closed reduction. No patient needed revision surgery for dislocation. Revision surgery was required by six (6%) patients, five for pain caused by acetabular wear and one for tumour progression. Amputation was needed in four patients for local
