The standard of wide tumour-like resection for chronic osteomyelitis (COM) has been challenged recently by adequate debridement. This paper reviews the evolution of surgical debridement for long bone COM, and presents the outcome of adequate debridement in a tertiary bone infection unit. We analyzed the retrospective record review from 2014 to 2020 of patients with long bone COM. All were managed by multidisciplinary infection team (MDT) protocol. Adequate debridement was employed for all cases, and no case of wide resection was included.Aims
Methods
Wide, tumor-like resection for chronic osteomyelitis (COM), a standard practice previously, has been challenged recently with adequate, local debridement. This paper reviews the evolution of surgical debridement for long bone osteomyelitis, and presents the outcome of adequate debridement in a tertiary bone infection unit. Retrospective review of records from 2014 to 2020 of patients with long bone osteomyelitis. All records were searched electronically and imaging reviewed. All patients were managed by Multidisciplinary Infection Team protocol.Introduction
Materials & Methods
This study investigated concurrent talar dome injuries associated with tibial pilon fractures, mapping their distribution across the proximal talar dome articular surface. It compared the two main mechanisms of injury (MOI), falling from a height and motor vehicle accident (MVA), and whether the fractures were open or closed. From a previously compiled database of acute distal tibial pilon fractures (AO/OTA 43B/C) in adults of 105 cases, 53 cases were identified with a concurrent injury to the talar dome with a known mechanism of injury and in 44 it was known if the fracture was open or closed. Case specific 2D injury maps were created using a 1×1mm grid, which were overlayed in an Excel document to allow for comparative analyses. A two-way ANOVA was conducted that examined the effect of both MOI and if the fracture was open or closed on what percentage of the talar dome surface was injured. There was a statistically-significant difference between the average percentage of injured squares on the talar dome by both whether the fracture was open or closed (f(1)=5.27, p= .027) and the mechanism of injury (f(1)=8.08, p= .007), though the interaction between these was not significant (p= .156). Open injuries and injuries that occurred during an MVA were more likely to increase the surface area of the talar dome injuries. We have identified both MOI and if the fracture was either open or closed impacts the size of the injury present on the talar dome. Future research will investigate the aetiology of the differences noted, highlighting the clinical implications. Surgeons treating tibial pilon fractures caused by either a MVA or an open fracture, should be aware of an increased risk of large injuries to the surface of the talar dome.
Tibial pilon fractures are typically the result of high-energy axial loads, with complex intra- articular fractures that are often difficult to reconstruct anatomically. Only nine simultaneous pilon and talus fractures have been published previously, but we hypothesised the chondral surface of the dome is affected more frequently. Data was acquired prospectively from 154 acute distal tibial pilon fractures (AO/OTA 43B/C) in adults. Radiographs, photographs, and intra-operative drawings of each case were utilised to document the presence of any macroscopic injuries of the talus. Detailed 1x1mm maps were created of the injuries in each case and transposed onto a statistical shape model of a talus; this enables the cumulative data to be analysed in Excel. Data was analysed using a Chi-squared test. From 154 cases, 104 were considered at risk and their talar domes were inspected; of these, macroscopic injuries were identified in 55 (52.4%). The prevalence of talar dome injury was greater with B-type fractures (53.5%) than C-type fractures (31.5%) ( Concomitant injuries to the articular surface of the dome of the talus are relatively common, and this perhaps explains the discordance between the post-operative appearance following internal fixation and the clinical outcomes observed. These injuries were focused on the lateral third of the dome in men and MVAs, whereas women and fall mechanism were more evenly distributed. Surgeons who operatively manage high-energy pilon fractures should consider routine inspection of the talar dome to assess the possibility of associated macroscopic osteochondral injuries.
Squamous cell carcinoma (SCC) is a rare but often devastating complication of chronic osteomyelitis. Optimum diagnosis and management are not well established. This paper aimed to develop a definitive, evidence-based approach to its diagnosis and management. A systematic review of relevant published studies available in English from 1999-present was conducted. Strict inclusion criteria ensured that the diagnoses of osteomyelitis and SCC were explicit and valid. Additional cases from our institution were included using the same eligibility criteria. Data regarding patient demographics, osteomyelitis diagnosis, SCC diagnosis and its management and patient outcomes were collected. Statistical significance was assessed by Fisher's exact test.Aim

Osteomyelitis (OM) is a challenging condition to diagnose and treat. The multidisciplinary team (MDT) approach is used in managing complex diseases such as cancer and diabetes. The Hull Regional Bone Infection MDT team was established to provide coordinated care for patients suspected to have OM. This study reviews the orthoplastic treatment and outcomes of patients with non-periprosthetic OM. Retrospective review of patients presenting to the MDT team who had orthoplastic intervention with debridement and flap coverage between 1/6/2014 - 30/11/2018. We describe our MDT approach of assessment, planning for surgical intervention and antibiotic protocol. Data was obtained from electronic and paper patient records, and PACS.Introduction
Materials and Methods
Despite advances in surgical and antibiotic therapies the treatment of chronic osteomyelitis remains complex and is often associated with a significant financial burden to the National Health Service. The aim of this review was to identify the different types of single-stage procedures being performed for this condition as well as to evaluate their effectiveness. Ovid Medline and Embase databases were searched for articles on the treatment of chronic osteomyelitis over the last 20 years. 3511 journal abstracts were screened by 3 independent reviewers. Following the exclusion of paediatric subjects, animal models, non-bacterial osteomyelitis and patients undergoing multiple surgical procedures we identified 13 studies reported in English with a minimum follow up of 12 months. Following a quality assessment of each study, data extraction was performed and the results analysed.Aim
Method
The management of chronic osteomyelitis is fraught with difficulties; a multi-disciplinary team approach is recommended for optimum outcome. Thorough debridement, dead space management and organism targeted antibiotic therapy the gives best clinical results. Calcium sulphate beads impregnated with antibiotic is an absorbable option for prolonged local antibiotic elution and dead space management. This study aims to analyse the early results of single stage management of osteomyelitis with antibiotic impregnated calcium sulphate beads. Following surgical debridement, calcium sulphate impregnated typically with tobramycin and/or vancomycin is inserted to obliterate the dead space. Intravenous antibiotics – typically teicoplanin and piperacillin-tazobactam – are administered until culture results permit rationalisation to narrow spectrum agents. Patients are followed up in Infectious Diseases and Orthopaedic clinics for a period of 12 months and discharged if quiescence is achieved. We conducted a retrospective analysis of our prospective database to identify patients treated with our single stage protocol for chronic osteomyelitis. We excluded patients that had (1) less than 6 months of follow up, (2) incomplete metal-ware removal, (3) patients lost to follow up. Fourteen patients (9 men, 5 women) with mean age of 41 (16–73) years and mean follow up of 9 (6–12) months were included in study. Eleven patients had previous surgeries involving internal fixation; the rest were primary osteomyelitis. Seven patients had washouts and removal of metal-ware procedures for osteomyelitis prior to referral to the bone infection service. Clinical, radiographic, and laboratory (microbiological, biochemical and haematological) methods were used to monitor response to treatment. Cierney-Mader classification determined that 8 patients were classed as type A (normal hosts); 4 as BS (systemically compromised); 2 as BLS (locally and systemically compromised). Anatomic analysis suggested 7 were Type 1 (medullary osteomyelitis); the remaining 7 were type 3 (localised disease). Five patients were staged IA; three each staged IIIA and IIIBS; and one each staged IBs, IBLS, IIIBLS. Staphylococcus Aureus was the commonest causative organism. Follow up radiograph monitoring indicated absorption of the beads by 3 months. There has been no evidence of recurrence based on clinical, radiographic and blood based parameters in all patients. Short-term results of single stage osteomyelitis treatment with calcium sulphate beads impregnated with antibiotics are promising.
Open fractures of the long bones of the limbs are associated with an increased risk of osteomyelitis and few studies investigate this complication in circular frames. We reviewed the incidence of and contributory factors toward infection-related outcomes in Grade 3 open fractures, managed with a circular frame, at a single centre. We performed a retrospective study of consecutive adult patients presenting with a Grade 3 open fracture, who required a circular frame for definitive skeletal fixation from 2005 to 2014. Patient case notes, microbiology results and radiological studies were reviewed for demographic details and surgical management. Infection-related outcomes were classified as ‘possible’ and ‘definitive’, based on clinical findings, microbiology and imaging features at follow-up at 6 and 12 months. 74 patients were identified with an average age of 43 years. There were 70 unilateral and 4 bilateral limb injuries. Most treated limbs had a tibial fracture (97%). There were 24 Gustillo-Anderson grade 3A, 37 grade 3B, 4 grade 3C and 9 not sub-classified. 33% of patients were debrided on the day of injury. Average time to circular frame installation was 14 days. 27 Ilizarov, 44 Taylor spatial and 3 other circular frames were used. A variety of plastic surgery reconstruction was used to provide wound coverage: skin grafts, local and free flaps. Circular frames were in place for 259 days on average. 10 patients (1 bilateral limb fracture) still have their frames in-situ. Additional bone grafting to the fracture site was carried out in 13 patients and 15 limbs (1 patient had 2 episodes of bone grafting to the same limb). 8 limbs in 8 patients were excluded from infection-related outcome analysis: 4 patients lost to follow-up, 2 patients who went on to below knee amputation and 2 patients had <6 months’ follow-up. 13 patients (14 limbs) had only 6 months’ follow-up and 53 patients (56 limbs) had 12 months’ follow-up. There were 5 patients (5 limbs) with ‘possible’ infection (7%): 1 screw infection and 4 soft tissue infections. 1 patient (1 limb) had a tissue-confirmed ‘definitive’ infected non-union (1.4%). Patients managed with circular frames typically have complex fracture configurations less amenable to other methods of definitive fixation. Our patient cohort has a limb salvage rate (97%) and a soft tissue infection rate (‘possible’ infection) comparable to other reported series. We report a low rate of osteomyelitis (‘definitive’ infection) in consecutive patients managed using our protocol.
– A multidisciplinary approach is essential to treat chronic osteomyelitis. Surgical debridement of macroscopic infection precedes targeted antibiotics to eradicate microscopic infection. This study analyses early results of our single-stage protocol for chronic osteomyelitis using antibiotic-impregnated calcium sulphate beads (Stimulan). – We retrospectively analysed patients with primary or secondary chronic osteomyelitis treated with Stimulan. Patients with incomplete metal-work removal or follow up less than 3 months were excluded. Our study focused on 15 patients (10 male) with an average age of 40.5 years (16–73 years), average follow up of 10.6 months (3 – 21 months). There were 12 cases of secondary osteomyelitis (3 primary). Majority of cases involved the tibia, femur or humerus. Following debridement Stimulan mixed with Vancomycin and/or tobramycin was placed to obliterate dead space and deliver local antibiotics. Intravenous antibiotics, typically piperacillin/tazobactam and/or teicoplanin, were administered post-operatively until tissue culture results were known – rationalised long term antibiotic regimen followed thereafter.Background:
Methods:
Chronic osteomyelitis still remains challenging and expensive to treat in spite of advances in antibiotics and operative techniques. We present our experience with free muscle flap after radical debridement of chronic osteomyelitis, performed as a single stage procedure. We retrospectively identified eight patients (5 Females) with mean age of 63 yrs (Range 40–71 yrs) Case notes were reviewed for co morbidities, Pre and post treatment inflammatory markers (plasma viscosity and CRP) and clinical staging. Mean follow up was 3 yrs (Range 1–6 yrs) All the patients were jointly operated by orthopaedic and plastic surgeons and underwent thorough debridement and muscle flap (Seven free flaps and one rotational flap) in the same sitting. All the patients were reviewed regularly by plastic and orthopaedic surgeons. Seven patients had free Gracilis flap and one had Triceps flap. Clinical assessment of reinfection was made on presence of erythema and wound discharge. Primary outcome measure was resolution of infection.Aim
