Aim. Debridement, antibiotics and implant retention (DAIR) are considered as an optimal curative treatment option for prosthetic joint infection (PJI) when the biofilm is still immature and radical debridement is achievable. There are two main groups of patients suitable for DAIR. Those with an early acute PJI and patients with acute hematogenous PJI. However, there is also a third group of early PJI resulting from a wound healing problem or leaking hematoma. These may be either high or low grade depending on the microorganisms that infected the artificial joint “per continuitatem”. Methods. We retrospectively analysed 100 successive DAIR procedures on prosthetic hip and knee joints performed between January 2010 and January 2022, from total of 21000 primary arthroplasties implanted within the same time period. We only included PJI in primary total replacements with no previous surgeries on the affected joint. Patients data (demographics, biochemical, microbiological, histopathological results, and outcomes) were collected from hospital bone and joint infection registry. The aim of surgery was radical debridement and the mobile parts exchange. The standardized antibiotic regime based on antibiofilm antibiotics. Results. The mean age of patients was 70 years (60% women, 43 hips, 57 knees) with a mean follow-up of 3 years. 45 cases were early acute or related to wound healing problems, 55 were hematogenous PJI. 25 patients received preoperative antibiotics. 6 of these were culture negative. The mean symptom duration was 7 days. Mean age of the prosthesis was 30 days for early, and 1064 days for the hematogenous group. Conclusions. In our cohort the success rate of DAIR is 94% which indicates that the protocol is highly successful in PJI with short-lasting symptoms and “debridable” joints. Antibiotic protocol violation and duration of symptoms may have a role in failures

Abstract. Background. Distinction between foot and ankle wound healing complications as opposed to infection is crucial for appropriate allocation of antibiotic therapy. Our aim was to evaluate the diagnostic accuracy of white cell count (WCC) and C-reactive protein (CRP) as diagnostic tools for this distinction in the non-diabetic cohort. Methods. Data were reviewed from a prospectively maintained Infectious Diseases Unit database of 216 patients admitted at Leicester University Hospitals – United Kingdom between July 2014 and February 2020 (68 months). All diabetic patients were excluded. For the infected non-diabetic included patients, we retrospectively retrieved the inflammatory markers (WCCs and CRP) at the time of presentation. Values of CRP 0–10 mg/L and WCC 4.0–11.0 ×109 /L were considered normal. Results. 25 patients met our inclusion criteria. Infections were confirmed microbiologically with positive intra-operative culture results. 7 (28%) patients with foot osteomyelitis (OM), 11 (44%) with ankle OM, 5 (20%) with ankle septic arthritis, and 2 (8%) patients with post-surgical wound infection were identified. Previous bony surgery was identified in 13 (52%) patients. 21 (84%) patients did have raised inflammatory markers while 4 (16%) patients failed to mount an inflammatory response even with subsequent debridement and removal of metalwork. CRP sensitivity was 84%, while WCC sensitivity was only 28%. Conclusion. CRP had good sensitivity, whereas WCC is a poor inflammatory marker in the detection of such cases. In presence of a clinically high level of suspicion of foot or ankle infection, a normal CRP should not rule out the diagnosis of OM

The optimal choice of irrigating solution or irrigating pressure in the initial management of open fracture wounds remains controversial. FLOW compared the effect of castile soap versus normal saline, and low versus high pressure pulsatile lavage on one year re-operation rates in patients with open fracture wounds. We conducted a multicentre, blinded, two-by-two factorial, pilot randomised trial of 111 patients with open fracture wounds receiving either castile soap solution or normal saline and either high or low pressure pulsatile lavage. The primary outcome, re-operation within one year, included infections, wound healing problems, and nonunions. Secondary outcomes included all operative and non-operative infections, wound healing problems, nonunion and functional outcomes. We followed the intention to treat principle. Eighty-nine patients (80.2%) completed the 12-month follow-up. As anticipated in this small-sample-size pilot study, results were compatible with substantial benefit and substantial harm. The hazard ratio (HR) for re-operation with castile soap was 0.77 (95% Confidence Interval (CI) 0.35 to 1.69, p=0.52). With low pressure lavage, the hazard ratio for the risk of re-operation was 0.56, 95% CI 0.25 to 1.27, p=0.17. Secondary outcomes showed a significant relative risk reduction for nonunion of 63% in favour of castile soap (p=0.036), and a trend for a relative risk reduction for nonunion of 44% in favour of low pressure lavage (p=0.22). Functional outcome scores showed no significant differences at any time point between groups. The FLOW pilot randomised controlled trial demonstrated the possibility that the use of low pressure may decrease the re-operation rate for infection, wound healing problems, or nonunion. Our findings provide compelling rationale for continued investigation in a pivotal FLOW trial of 2280 patients

Introduction. Femoral shaft fractures in children is a serious injury that needs hospitalization, with a high prevalence in the age group 6–8 years old. Various treatment options are available and with a comparable weight of evidence. Submuscular plating provides a dependable solution, especially in length-unstable fractures and heavier kids. We present a novel technique to facilitate and control the reduction intraoperatively, which would allow for easier submuscular plate application. Materials and Methods. We have retrospectively reviewed four boys and three girls; all were operated in one centre. Polyaxial clamps and rods were applied to the sagittally-oriented bone screws, the reduction was done manually, and the clamps were tightened after achieving the proper alignment in the anteroposterior and lateral fluoroscopy views. The submuscular plate was applied as described, then clamps and bone screws were removed. Results. The mean age at surgery was 13 years (range, 9–14). The mean body weight was 43.3 kg (range, 30–66). There were five mid-shaft fractures, one proximal third and one distal third. There were Four type A fractures, two type B and one type C. Four patients had road traffic accidents while three had direct trauma. The mean preoperative haemoglobin concentration 12.5 g/dl (range 11.3–13 g/dl). No blood transfusion was needed intraoperatively or postoperatively. The operative time averaged 122 minutes, and the mean hospital stay was one (range 1–4 days). The patients reported no pain at a mean of 1.5 weeks (range, one-three weeks). All fractures united at a mean of 8.7 weeks (range 6–12 weeks). No wound healing problems nor deep infections happened. The knee joint range of motion was full in all patients at six weeks postoperatively. There was no mechanical irritation from the inserted plate. At the final follow-up, all fractures united without malalignment nor length discrepancy. Conclusions. External fixator-assisted internal fixation of pediatric femoral fractures would facilitate the accuracy and control of fracture reduction and allow minimally invasive percutaneous osteosynthesis. Our study has shown a decrease in operative time, and an accompanying reduction in length of inpatient stay, prolonged need for analgesia and post-operative rehabilitation

Wound complications are much more common following knee arthroplasty compared to hip arthroplasty. This is because of the precarious blood supply which contributes to the infection rate which is about twice as high. Many, if not most, infections are related to wound problems. Avoiding wound problems is a critical issue in joint replacement, more so in the knee than the hip. The volume of these procedures is growing rapidly. Infection continues to be a major complication. The incidence is not decreasing and infections are becoming more difficult to treat, because of resistant organisms. Also, the increasing number of procedures in patients with obesity and other risk factors makes wound management a major issue in knee replacement. Many wound problems are avoidable and can be minimised by care to detail by the surgeon. Salvaging the problem wound is a major issue in total knee replacement currently in order to minimise infection, which remains a major issue and is frequently related to wound healing problems. The first step is identifying the patient at risk and either deferring surgery or optimising the patient to minimise the risk of wound healing problems and subsequent infection. Secondly, is appropriate soft tissue handling with careful attention to choosing the optimal skin incision. Third is taking steps to facilitate primary wound healing and absolutely minimising the risk of persistent drainage, particularly through the very judicious use of anticoagulants. Finally, the delayed wound healing and persistent drainage must be identified early and treated aggressively in order to minimise the risk of infection

Multiple newer wound closure techniques have been recently developed with the goals being reducing closure time, enhancing cosmesis, and decreasing wound healing problems including infections. Among these techniques are the zipper-like closure, absorbable dermal staples, scaffold devices, and others. Each of these techniques propose certain advantages. Nevertheless, this comes at an added cost and careful weighing of the cost/benefit should be considered in an evidence-based manner, in order to guide future recommendations for using these techniques

Purpose. The evolution of locked anatomical clavicular plating in combination with evidence to suggest that fixation of clavicle fractures yields better outcome to conservative treatments has led to an increasing trend towards operative management. There is no evidence however to compare early fixation with delayed reconstruction for symptomatic non- or mal-union. We hypothesize that early intervention yields better functional results to delayed fixation. Methods. Between August 2006 and May 2010, 97 patients were managed with operative fixation for their clavicular fracture. Sixty eight with initial fixation and 29 delayed fixation for clavicular non- or mal-union. Patients were prospectively followed up to radiographic union, and outcomes were measured with the Oxford Shoulder Score, QuickDASH, EQ5D and a patient interview. Mean follow-up was to 30 months. All patients were managed with Acumed anatomical clavicular plates. Results. The radiographic and clinical outcomes were available for all patients. Scores were available for 62 (62/97). There were no statistically significant differences in age (p>0.05), sex (p>0.05), energy of injury (p>0.05), number of open fractures (p>0.05) between the two groups. The mean quickDASH was 8.9 early, 9.1 delayed (p< 0.05), Oxford Shoulder score was 15.7 early, 16.1 delayed (p< 0.05). In the early fixation group 5 patients had wound healing complications, and 8 went on subsequently to have removal of prominent metalwork. In the delayed fixation group 2 had wound healing complications and 4 had removal of prominent metalwork. There were no statistically significant differences in the EQ5D quality of life questionnaire. Conclusion. There are no statistically significant differences in shoulder performance, wound or operative complications between early and delayed fixation of clavicular fractures. Our series does not support early fixation of clavicular fractures, as results for delayed intervention in those who become symptomatic appear comparable

Aims

Chronic osteomyelitis (COM) of the lower limb in adults can be surgically managed by either limb reconstruction or amputation. This scoping review aims to map the outcomes used in studies surgically managing COM in order to aid future development of a core outcome set.

Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) is a devastating complication. It is associated with high morbidity and mortality. It remains, unfortunately, one of the most common modes of failure in TKA. Much attention has been paid to the treatment of PJI once it occurs. Our attention, however, should focus on how to reduce the risk of PJI from developing in the first place. Infection prevention should focus on reducing modifiable risk factors that place patients at increasing risk for developing PJI. These areas include pre-operative patient optimization and intra-operative measures to reduce risk. Pre-operative Modifiable Risk Factors: There are several patient related factors that have been shown to increase patient's risk of developing PJI. Many of these are modifiable risk factors can and should be optimised prior to surgery. Obesity and in particular Morbid Obesity (BMI >40) has a strong association with increased risk of PJI. Appropriate and healthy weight loss strategies should be instituted prior to elective TKA. Uncontrolled Diabetes (Hgb A1C >8) and poor glycemic control around the time of surgery increases the risk for complications, especially PJI. Malnutrition should be screened for in at-risk patients. Low Albumin levels are a risk factor for PJI and should be corrected. Patients should be required to stop smoking 6 weeks prior to surgery to lower risk. Low Vitamin D levels have been show to increase risk of PJI. Reduction of colonization of patient's nares with methicillin sensitive (MSSA) and resistant (MRSA) staphylococcus should be addressed with a screen and treat program. Intra-operative Measures to Reduce PJI: During surgery, several steps should be taken to reduce risk of infection. Appropriate dosing and timing of antibiotics is critical and a first generation cephalosporin remains the antibiotic of choice. The use of antibiotic cement remains controversial with regards to its PJI prophylactic effectiveness. The utilization of a dilute betadine lavage has demonstrated decreased rate of PJI. Maintaining normothermia is critical to improve the body's ability to fight infection. An alcohol-based skin preparation can reduce skin flora as a cause of PJI. Appropriate selection of skin incisions and soft tissue handling can reduce wound healing problems and reduce development of PJI. Likewise, the use of occlusive dressing has been shown to promote wound healing and reduce PJI rates

INTRODUCTION. The direct anterior approach to THR has become an increasingly popular minimally-invasive technique in an effort to minimize dislocation risk, facility early recovery, and diminish soft tissue injury. However, it has been associated with unique complications including intraoperative femur fracture, cutaneous nerve palsy, stem subsidence, and wound healing complications. These risk of these complications have been documented to be more likely in the surgeon's early experience with the approach. The minimally-invasive Supercapsular Percutaneous-Assisted (SuperPATH) technique was developed to minimize capsular and short-external rotator injury, minimize dislocation risk, and provide an easier transition from the standard posterior approach. METHODS. Fifty (50) consecutive elective total hip replacements in 48 patients were performed using the SuperPATH technique. These also represented the first fifty elective THRs the surgeon performed in practice. Indications were primary or secondary osteoarthritis (92%), avascular necrosis (6%), and impending pathologic fracture (2%). Patients were evaluated retrospectively for dislocation, major, and minor complications. RESULTS. At average follow-up of 10.9 months (Range 1–27 months), there were no dislocation events. There was one periprosthetic fracture identified at 14-day follow-up that required femoral revision surgery in an elderly female patient with osteoporosis. Otherwise, there were no reoperations for any reason. There were no wound complications or deep infections. There was one stem subsidence (2%) of 4 mm. There were no neurovascular injuries. CONCLUSION. The SuperPATH technique can likely be performed at an early experience level with low early complication risk and lower early dislocation risk. This minimally-invasive technique deserves further interest and evaluation as it may present a gentle learning-curve to surgeons

Interest in minimal-incision total knee arthroplasty (TKA) has increased in recent years. The advantages of minimally invasive techniques (MIS) used for TKA are faster functional recovery, shorter hospital stay and better early knee range of motion. It is known that the long-term outcome after TKA is related to component position and ligament balance. The smaller incision in MIS might be associated with increased risk of malalignment of components due to limited visualisation. Malalignment of implants in TKA has been associated with implant failure and poor long-term functional results. There is a lack of evidence in the literature that MIS can achieve the same results as the standard TKR approach in terms of component alignment precision. Seventy patients scheduled for a primary TKA were prospectively evaluated postoperatively with coronal and sagittal radiographic long limb films. Mini-midvastus approach was used for all TKA. There were no complications and the radiographic evaluation found no implant or limb malalignment, or signs of early loosening. We did not observe wound healing problems, fractures or implant notching. The mini-midvastus approach can reproduces the same accuracy in component positioning as the standard medial parapatellar approach. A precise operation technique and adequate visualisation of anatomical landmarks during implantation are the key points of success in mini-midvastus approach

Obtaining primary wound healing in Total Joint Arthroplasty (TJA) is essential to a good result. Wound healing problems can occur and the consequences can be devastating to the patient and to the surgeon. Determination of the host healing capacity can be useful in predicting complications. Cierney and Mader classified patients as Type A: no healing compromises and Type B: systemic or local healing compromises factors present. Local factors include traumatic arthritis with multiple previous incisions, extensive scarring, lymphedema, poor vascular perfusion, and excessive local adipose deposition. Systemic compromising factors include diabetes, rheumatic diseases, renal or liver disease, immunocompromise, steroids, smoking, and poor nutrition. In high risk situations the surgeon should encourage positive patient choices such as smoking cessation and nutritional supplementation to elevate the total lymphocyte count and total albumin. Careful planning of incisions, particularly in patients with scarring or multiple previous operations, is productive. Around the knee the vascular viability is better in the medial flap. Thusly, use the most lateral previous incision, do minimal undermining, and handle tissue meticulously. We do all potentially complicated TKAs without tourniquet to enhance blood flow and tissue viability. The use of peri-operative anticoagulation will increase wound problems. If wound drainage or healing problems do occur immediate action is required. Deep sepsis can be ruled out with a joint aspiration and cell count [less than 2500], differential [less than 60% polys], and negative culture and sensitivity. All hematomas should be evacuated and necrosis or dehiscence should be managed by debridement to obtain a live wound

Biological reconstruction techniques after diaphyseal tumour resection have increased in popularity in recent years. High complication and failure rates have been reported with intercalary allografts, with recent studies questioning their role in limb-salvage surgery. We developed a technique in which large segment allografts are augmented with intramedullary cement and fixed using compression plating. The goal of this study was to evaluate the survivorship, complications and functional outcomes of these intercalary reconstructions. Forty-two patients who had reconstruction with an intercalary allograft following tumour resection between 1989 and 2010 were identified from our prospectively collected database. Allograft survival, local recurrence-free, disease-free and overall survival were assessed using the Kaplan-Meier method. Patient function was assessed using the Musculoskeletal Tumour Society (MSTS) scoring system and the Toronto Extremity Salvage Score (TESS). The 23 women and 19 men had a mean age of 33 years (14–77). The most common diagnoses were osteosarcoma (n=16) and chondrosarcoma (n=9). There were 9 humerus, 18 femur and 15 tibia reconstructions. At a mean follow-up of 95 months (5–288), 31 patients were alive without disease, 10 were dead of disease and 1 was deceased of other causes. There were 4 local recurrences and 11 patients developed metastatic disease. 5-year local recurrence free survival was 92%, 5-year disease-free survival was 70% and overall survival was 75%. Fourteen of 42 patients (33%) experienced complications: 5 wound healing complications, 4 infections, 2 non-unions, 2 fractures and 1 nerve palsy. Four allografts (9.5%) were revised for complications and 2 (5%) for local recurrence. Mean allograft survival was 85 months (4–288). Mean time to union was 8.2 (3–36) months for the proximal osteotomy site and 8.1 (3–23) months for the distal osteotomy site. The mean score for MSTS 87 was 29.4 (+/− 4.4), MSTS 93 was 83.7 (+/−14.8) and TESS was 81.6 (+/−16.9). An intercalary allograft augmented with intramedullary cement and compression plate fixation provides a reliable and durable method of reconstruction after tumour resection. Complication rates are comparable to the literature and are associated with high levels of patient function and satisfaction

Wound complications are much more common following knee arthroplasty as compared to hip arthroplasty, due in part to the precarious blood supply to the knee, as well as the subcutaneous position of the joint. Many, if not most, infections are related to wound problems, and thus avoiding wound problems is a critical issue in knee replacement surgery. Many wound problems are avoidable and can be minimised by care to detail by the surgeon. The important steps are to first identify patients at risk and optimally addressing these risk factors. Patient risk factors include: chronic corticosteroid use, diabetes, rheumatoid arthritis, malnutrition, obesity, and smoking. Soft tissue handling is a second major issue. Minimal incision surgery should be used with great caution for knee replacements since the skin is much less forgiving than in hip replacements. A midline skin incision should be utilised when possible. When multiple incisions are present it is usually advisable to use the lateral most incision through which it is feasible to perform a knee replacement. In rare cases, a soft tissue expander may be used preoperatively for thin, adherent skin. Perioperative steps that can be taken include delaying CPM in high risk wounds, and using a wound vac system in obese or other high risk wounds to minimise persistent drainage. Furthermore, anticoagulation should be used judiciously to avoid prolonged drainage. The final step in salvaging the problem wound is early recognition and aggressive management of wound healing problems. Prolonged, serous drainage is the most common clinical scenario. Drainage that is increasing beyond 5–7 days frequently requires evacuation, irrigation, debridement, and liner exchange. Early aspiration can decompress a hematoma and also rule out infection

Introduction. The legacy constrained condylar knee prosthesis (LCCK, Zimmer.) is designed for primary and revision total joint arthroplasties that need additional stability due to ligament deficiency and to compensate for bone defects. In this follow-up we present our mid term results. Methods and Material. Between November 1999 and January 2006 59 patients were provided with 67 LCCK knee endoprotheses. 38 prostheses were implanted in cases of revision surgery and 29 as primary implants. The mean patient age was 76 years (range 22–93). Indications for revisions were 20 aseptic loosenings, 11 late infections, 7 instabilities (5 cases due to polyethylene wear). Indications for primary arthroplasties were 16 severe valgus and 7 severe varus deformities, 5 cases of osteoarthritis after infection and 1 posttraumatic deformity. 36 femur components (54%) and 34 tibia components (51%) were augmented. 31 stems were fixed cementless, 15 stems were cemented (6 with an intermedullary plug). We evaluated the results prospectively with a clinical inspection and x-ray. Clinical rating systems used were the Knee society, SF-36 Quality of life and Womac score. The mean follow up was 5.6 years. 42 patients were examined, 10 questioned on the telephone, 3 deceased, 12 had to be revised and 2 were lost for follow-up. Results. We had an increase in ROM from 93° to 110°. The Knee Society score improved from 40 to 75 and the function score improved from 46 to 72. The early complications included 1 peroneal lesion, 1 intraoperative fracture, 7 limitations in movement, 10 wound healing problems and 1 thrombosis. 12 revisions had to be performed. 1 septic loosening, 1 synovectomy, 4 aseptic loosenings, 3 secondary patella replacements, 1 traumatic rupture of the quadriceps muscle, 1 chondrosacroma and 1 revision performed in another clinic. 25 (80%) uncemented stems, 3 (33%) cemented stems and 1 (17%) of the stems cemented with an intramedullary plug showed radiolucencies. Conclusion. The LCCK prosthesis can be recommended as a primary implant and for revisions in cases of severe instability or severe bone loss. Due to the bad general health of the patients and preoperative situation of the knee joints the results are satisfactory. All revisions due to aseptic loosening had to be performed on LCCKs with uncemented stems

Obtaining primary wound healing in Total Joint Arthroplasty (TJA) is essential to a good result.

Cierney and Mader classified patients as Type A: no healing compromises and Type B: systemic or local healing compromises factors present.

Options available for coverage of complex wound problems include myocutaneous flaps, pedicled skin flaps, and skin grafts. Wet, occlusive dressings and wound VACs encourage epithelisation of chronic wounds

The purpose of the study was to identify factors that affect the incidence of deep wound infection after hip fracture surgery. Data from a hip fracture database of 7057 consecutively treated patients at a single centre was used to determine the relationship between deep wound sepsis and a number of factors. Fisher's exact test and the unpaired T test were used. All patients were initially followed up in a specialist clinic. In addition a phone call assessment was made at one year from injury to check that no later wound healing complications had occurred. There were 50 cases of deep infection (rate of 0.7%). There was no significant difference in the rate of deep sepsis with regards to the age, sex, pre-operative residential status, mobility or mental test score of the patient. Specialist hip surgeons and Consultants have a lower infection rate compared with surgeons below Consultant grade, p=0.01. The mean length of anaesthesia was longer in the sepsis group (76minutes) compared to the no sepsis group (65minutes), this was significant, p=0.01. The patient's ASA grade and fracture type were not significant factors. The rate of infection in intracapsular fractures treated by hemiarthroplasty was significantly greater than those that had internal fixation, p=0.001. The rate of infection in extracapsular fractures fixed with an extra-medullary device was significantly greater than those fixed with an intra-medullary device, p=0.021. The presence of an infected ulcer on the same leg as the fracture was not associated with a higher rate of deep infection. In conclusion we have found that the experience (seniority) of the surgeon, the length of anaesthesia and the type of fixation used are all significant factors in the development of deep sepsis. These are all potentially modifiable risk factors and should be considered in the treatment of hip fracture patients

Background. Advances in diagnosis and treatment should mean that hindquarter amputation is now rarely needed. Unfortunately this is not the case. We have performed 166 of these amputations in the past 36 years. We have investigated the reasons why this procedure is still required and the outcomes following it. Method. A retrospective review of data stored on a prospective database. Results. Hindquarter amputation was used as treatment for 15% of all primary bone tumours affecting the pelvis. 146 were performed with curative intent but 20 were performed purely for palliation, usually to relieve pain. 96 of the procedures were needed as part of primary treatment, with the other 70 being needed following failure of local control after other surgical procedures. The indication for amputation in primary disease was almost always due to a significant delay in diagnosis, allowing tumours (particularly chondrosarcomas) to become massive by the time of diagnosis. The peri-operative mortality was 3% and 45% had major wound healing problems or infection. The median survival times after curative and palliative procedures were 36 months and 8 months respectively. The survival after hindquarter amputation for curative intent at 1, 3 and 5 years was 74%, 60% and 48%. Overall survival was better with chondrosarcoma – 52% of the patients surviving more than 10 years had chondrosarcoma. Phantom pain was a significant problem; fewer than 10% use their prosthesis regularly. Despite this functional scores averaged 61% – not significantly worse than patients who had undergone pelvic replacements!. Conclusion. Hindquarter amputation is still regularly required both for primary and salvage treatment in musculoskeletal oncology. Earlier diagnosis of pelvic tumours may avoid its use. Survival is not surprisingly worse than for tumours at other sites

Introduction. Infection following traumatic injury of the tibia is challenging, with surgical debridement and prolonged systemic antibiotic therapy well established. Local delivery via cement beads has shown improved outcome, but these often require further surgery to remove. Osteoset-T is a bone-graft substitute composed of calcium sulphate and 4%-Tobramycin, available in pellets that are packed easily into bone defects. Concerns remain regarding the sterile effluent produced as it resorbs, along with the risk of acute kidney injury following systemic absorption. Purpose. We present outcomes of 22 patients treated with Osteoset-T. Methods. Medical notes were reviewed of every case of osteomyelitis of the tibia over a 30-month period, in which Osteoset-T had been used. Excision of infected soft tissue and tibial debridement was performed. Metalwork whenever present removed, before Osteoset-T pellets were packed into any cortical defects or the intra-medullary canal. Further stabilisation (n=9) and soft tissue reconstruction (n=7) was undertaken as required. Intravenous vancomycin and meropenem was administered after sampling. Meropenem discontinued after 3 days if no gram negatives cultured, and vancomycin continued for 1 week. Thereafter targeted antibiotic therapy given for 6 weeks, or ciprofloxacin and rifampicin orally if no growth. Results. Average follow-up was 16 months, with wound complications encountered in 50%. A wound discharge in the early post-operative period was noted in 8 patients (36%) independent of site of Osteoset-T placement, with 6 demonstrating wound healing complications. Whereas only 5 of 14 patients without wound leak developed wound complications, but the difference did not reach significance (p=0.18, Fisher exact test). Union rate and infection eradication was 100%, with only one patient developing a transient acute kidney injury. Conclusion. Despite a high incidence of wound discharge that may promote healing complications, Osteoset-T is an effective adjunct in treatment of chronic tibial osteomyelitis following trauma, with nephrotoxicity concerns not warranted
