Aims. To describe the risk of periprosthetic joint infection (PJI) and reoperation in patients who have an acute, traumatic wound dehiscence following total knee arthroplasty (TKA). Methods. From January 2002 to December 2018, 16,134 primary TKAs were performed at a single institution. A total of 26 patients (0.1%) had a traumatic wound dehiscence within the first 30 days. Mean age was 68 years (44 to 87), 38% (n = 10) were female, and mean BMI was 34 kg/m. 2. (23 to 48). Median time to dehiscence was 13 days (interquartile range (IQR) 4 to 15). The dehiscence resulted from a fall in 22 patients and sudden flexion after staple removal in four. The arthrotomy was also disrupted in 58% (n = 15), including a complete extensor mechanism disruption in four knees. An irrigation and debridement with component retention (IDCR) was performed within 48 hours in 19 of 26 knees and two-thirds were discharged on antibiotic therapy. The mean follow-up was six years (2 to 15). The association of wound dehiscence and the risk of developing a PJI was analyzed. Results. Patients who sustained a traumatic wound dehiscence had a 6.5-fold increase in the risk of PJI (95% confidence interval (CI) 1.6 to 26.2; p = 0.008). With the small number of PJIs, no variables were found to be significant risk factors. However, there were no PJIs in any of the patients who were treated with IDCR and a course of antibiotics. Three knees required reoperation including one two-stage exchange for PJI, one repeat IDCR for PJI, and one revision for aseptic loosening of the tibial component. Conclusion. Despite having a traumatic wound dehiscence, the risk of PJI was low, but much higher than experienced in all other TKAs during the same period. We recommend urgent IDCR and a course of postoperative antibiotics to decrease the risk of PJI. A traumatic wound dehiscence increases risk of PJI by 6.5-fold.

Background. There are limited data on the complication rates and risk of periprosthetic joint infection (PJI) in patients who have an acute wound dehiscence after total knee arthroplasty (TKA). Methods. From 2002 to 2018, 16,134 primary TKAs were performed at a single institution. Twenty-six patients (0.1%) had a traumatic wound dehiscence within the first 30 days. Mean age was 68, 38% were female, and mean BMI was 33 kg/m2. Median time to dehiscence was 13 days. The dehiscence resulted from a fall in 22 cases, including 4 in-hospital falls (3 with femoral nerve blocks), and sudden flexion after staple removal in 4 cases. The arthrotomy was disrupted in 58%, including a complete extensor mechanism disruption in 4 knees. A surgical debridement was performed within 48 hours in 19 of 26 knees. Two-thirds were discharged on antibiotic therapy. Results. Only two knees were complicated by PJI (cumulative incidence of 11% vs. 1% in all other primary TKAs, HR 6.5, p <0.01). One patient who developed a PJI was initially treated with a bedside closure in the ER rather than surgical debridement. The second patient had a complete extensor mechanism disruption at the time of dehiscence and was treated with surgical debridement, but did not receive a subsequent course of antibiotics. There were no PJIs in any of the cases that were treated with surgical debridement and a course of antibiotics. Three knees required reoperation (cumulative incidence of reoperation was 16% at 2 years, compared to 6% in all other primary TKAs, p=0.32) including 1 two-stage exchange for PJI, 1 irrigation and debridement with component retention for PJI, and 1 revision for tibial component aseptic loosening. Conclusion. Despite having a traumatic wound dehiscence, with nearly 60% resulting in arthrotomies that exposed implants, the risk of PJI was low but significantly higher than not having a traumatic arthrotomy. We recommend urgent surgical irrigation and debridement, inspection of arthrotomy integrity, and antibiotic treatment to decrease the risk of PJI. Summary. An acute, traumatic wound dehiscence with in the first 30 days after primary TKA results in a 11% risk of infection at 2 years

Aims:. Identifying and scoring risk factors that predict early wound dehiscence and progression to metalwork infection. Results of wound healing, eradication of infection and union of with the use of vacuum dressing. Compare results of serial washouts against early vacuum dressing in this group of children with significant medical co-morbidities. Method:. A retrospective review of 300 patients with neuromuscular scoliosis who underwent posterior instrumented correction and fusion between 2008 and 2012 at two institutions. 10 patients had an early wound dehiscence which progressed to deep seated infection requiring wound washout(s) and subsequent vacuum dressing. Medical notes, clinical photographs and imaging were reviewed. Minimum follow up period was 14 months. Results:. This study shows that readmission to PICU, presence of viscero-cutaneous devices (e.g. PEG, tracheostomy), restrictive lung disease, concomitant infection, polymicrobial (gram negative) organism and hyperlordotic deformities are cumulative risk factors to developing early wound dehiscence leading to deep seated infections. All patients in our series went on to have a sealed, non infected wound with union confirmed on CT. Patients who had multiple serial washouts (n=3–7), eventually required vacuum dressing. Discussion:. By stratifying risk factors in patients with neuromuscular scoliosis, the occurrence of wound dehiscence can be predicted. With higher risk factor scores, early vacuum dressing is recommended as multiple serial wound washouts have poor results and with added morbidity to the patient.

Aims. Frailty has been gathering attention as a factor to predict surgical outcomes. However, the association of frailty with postoperative complications remains controversial in spinal metastases surgery. We therefore designed a prospective study to elucidate risk factors for postoperative complications with a focus on frailty. Methods. We prospectively analyzed 241 patients with spinal metastasis who underwent palliative surgery from June 2015 to December 2021. Postoperative complications were assessed by the Clavien-Dindo classification; scores of ≥ Grade II were defined as complications. Data were collected regarding demographics (age, sex, BMI, and primary cancer) and preoperative clinical factors (new Katagiri score, Frankel grade, performance status, radiotherapy, chemotherapy, spinal instability neoplastic score, modified Frailty Index-11 (mFI), diabetes, and serum albumin levels). Univariate and multivariate analyses were developed to identify risk factors for postoperative complications (p < 0.05). Results. Overall, 57 postoperative complications occurred in 47 of 241 (19.5%) patients. The most common complications were wound infection/dehiscence, urinary tract infection, and pneumonia. Univariate analysis identified preoperative radiotherapy (p = 0.028), mFI (p < 0.001), blood loss ≥ 500 ml (p = 0.016), and preoperative molecular targeted drugs (p = 0.030) as potential risk factors. From the receiver operating characteristic curve, the clinically optimal cut-off value of mFI was 0.27 (sensitivity, 46.8%; specificity, 79.9%). Multivariate analysis identified mFI ≥ 0.27 (odds ratio (OR) 2.94 (95% CI 1.44 to 5.98); p = 0.003) and preoperative radiotherapy (OR 2.11 (95% CI 1.00 to 4.46); p = 0.049) as significant risk factors. In particular, urinary tract infection (p = 0.012) and pneumonia (p = 0.037) were associated with mFI ≥ 0.27. Furthermore, the severity of postoperative complications was positively correlated with mFI (p < 0.001). Conclusion. The mFI is a useful tool to predict the incidence and the severity of postoperative complications in spinal metastases surgery. Cite this article: Bone Joint J 2024;106-B(12):1469–1476

Aim. In the context of total knee arthroplasty (TKA), trauma with perigenicular fracture fixation or oncological surgical treatment, soft tissue defects can expose critical structures such as the extensor apparatus, the knee joint, bone or implants. This work compares soft tissue reconstruction (STR) between a classical pedicled gastrocnemius (GC) muscle flap and a pedicled chimeric sural artery perforator (SAP) musculocutaneous GC flap in complex orthoplastic scenarios. Method. A retrospective study was conducted on prospectively maintained databases in three University Hospitals from January 2016 to February 2021 after orthopaedic, traumatological or oncological treatment. All patients with a perigenicular soft tissue defect and implant-associated infection were included undergoing STR either with a pedicled GC flap or with a pedicled chimeric SAP-GC flap. The outcome analysis included successful STR and flap related complications. The surgical timing, preoperative planning and surgical technique are discussed together with the postoperative rehabilitation protocol. Results. 43 patients were included (22 GC muscle flaps, 21 SAP-GC musculocutaneous flaps). The GC and SAP-GC patient group were comparable in terms of age, comorbidities, defect size and follow-up. The incidence of flap related complications was comparable among the two groups. Specifically, in the SAP-GC group 1 wound dehiscence at the recipient site occurred as well as 1 distal muscle flap necrosis, 1 distal skin flap necrosis, 1 donor site infection and 1 donor site wound dehiscence. Furthermore, the donor site was closed in 9 patients while a skin graft was used in 12 patients. A significant difference was recorded with regard to re-raising the flap for further orthopaedic treatment: In the SAP-CG group (re-raise in 11 patients) no problems occurred while in the GC group (re-raise in 14 patients) in 6 patients the soft tissue did not heal completely. Conclusions. According to our clinical experience, the pedicled chimeric SAP-CG musculocutaneous flap is a relevant further development of the classical GC workhorse flap for perigenicular STR, in multiple staged procedures

Aims. Reconstruction after osteoarticular resection of the proximal ulna for tumours is technically difficult and little has been written about the options that are available. We report a series of four patients who underwent radial neck to humeral trochlea transposition arthroplasty following proximal ulnar osteoarticular resection. Methods. Between July 2020 and July 2022, four patients with primary bone tumours of the ulna underwent radial neck to humeral trochlea transposition arthroplasty. Their mean age was 28 years (12 to 41). The functional outcome was assessed using the range of motion (ROM) of the elbow, rotation of the forearm and stability of the elbow, the Musculoskeletal Tumor Society score (MSTS), and the nine-item abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH-9) score. Results. All patients were available for follow-up at a mean of 33 months (25 to 43) and were disease-free. The mean flexion arc was 0° to 105°. Three patients had complications. One had neuropraxia of the ulnar nerve. The symptoms resolved after three months. In one patient, the screw used for fixation of the triceps tendon became exposed and was removed, six months postoperatively. One patient with wound dehiscence required a local flap for soft-tissue cover, four months postoperatively. At a mean follow-up of 33 months (25 to 43), the mean flexion arc was 0° to 105°. All patients had full supination (85°) but none had any pronation. The mean MSTS score was 23.5 (23 to 24) and mean QuickDASH-9 score was 26.13 (16.5 to 35.75). Three patients had varus-valgus instability on examination, although only one had a sense of instability while working. Conclusion. Radial neck to humeral trochlea transposition offers a satisfactory and cost-effective biological reconstructive option after osteoarticular resection of the proximal ulna, in the short term. It provides good elbow function and, being a biological reconstruction option using native bone, is likely to provide long-term stability and durability.

Aims. Tibial tubercle osteotomy (TTO) facilitates surgical exposure and protects the extensor mechanism during revision total knee arthroplasty (rTKA). The purpose of this study was to determine the rates of bony union, complications, and reoperations following TTO during rTKA, to assess the functional outcomes of rTKA with TTO at two years’ minimum follow-up, and to identify the risk factors of failure. Methods. Between January 2010 and September 2020, 695 rTKAs were performed and data were entered into a prospective database. Inclusion criteria were rTKAs with concomitant TTO, without extensor mechanism allograft, and a minimum of two years’ follow-up. A total of 135 rTKAs were included, with a mean age of 65 years (SD 9.0) and a mean BMI of 29.8 kg/m. 2. (SD 5.7). The most frequent indications for revision were infection (50%; 68/135), aseptic loosening (25%; 34/135), and stiffness (13%; 18/135). Patients had standardized follow-up at six weeks, three months, six months, and annually thereafter. Complications and revisions were evaluated at the last follow-up. Functional outcomes were assessed using the Knee Society Score (KSS) and range of motion. Results. The mean follow-up was 51 months (SD 26; 24 to 121). Bony union was confirmed in 95% of patients (128/135) at a mean of 3.4 months (SD 2.7). The complication rate was 15% (20/135), consisting of nine tibial tubercle fracture displacements (6.7%), seven nonunions (5%), two delayed unions, one tibial fracture, and one wound dehiscence. Seven patients (5%) required eight revision procedures (6%): three bone grafts, three osteosyntheses, one extensor mechanism allograft, and one wound revision. The functional scores and flexion were significantly improved after surgery: mean KSS knee, 48.8 (SD 17) vs 79.6 (SD 20; p < 0.001); mean KSS function, 37.6 (SD 21) vs 70.2 (SD 30; p < 0.001); mean flexion, 81.5° (SD 33°) vs 93° (SD 29°; p = 0.004). Overall, 98% of patients (n = 132) had no extension deficit. The use of hinge implants was a significant risk factor for tibial tubercle fracture (p = 0.011). Conclusion. TTO during rTKA was an efficient procedure to improve knee exposure with a high union rate, but had significant specific complications. Functional outcomes were improved at mid term.

Aims. This study aimed to assess the risk of acute kidney injury (AKI) associated with combined intravenous (IV) and topical antibiotic therapy in patients undergoing treatment for periprosthetic joint infections (PJIs) following total knee arthroplasty (TKA), utilizing the Kidney Disease: Improving Global Outcomes (KDIGO) criteria for classification. Methods. We conducted a retrospective analysis of 162 knees (162 patients) that received treatment for PJI post-TKA with combined IV and topical antibiotic infusions at a single academic hospital from 1 January 2010 to 31 December 2022. The incidence of AKI was evaluated using the KDIGO criteria, focussing on the identification of significant predictors and the temporal pattern of AKI development. Results. AKI was identified in 9.26% (15/162) of the cohort, predominantly presenting as stage 1 AKI, which was transient in nature and resolved prior to discharge. The analysis highlighted moderate anaemia and lower baseline serum creatinine levels as significant predictors for the development of AKI. Notably, the study found no instances of severe complications such as wound dehiscence, skin erosion, or the need for haemodialysis following treatment. Conclusion. The findings suggest that the combined use of IV and topical antibiotic therapy in the management of PJIs post-TKA is associated with a low incidence of primarily transient stage 1 AKI. This indicates a potentially favourable renal safety profile, advocating for further research to confirm these outcomes and potentially influence treatment protocols in PJI management.

Background. Surgical wound closure is not the surgeon”s favorite part of the total knee arthroplasty (TKA) surgery however it has vital rule in the success of surgery. Knee arthoplasty wounds are known to be more prone to infection, breakdown or delayed healing compared to hip arthroplasty wounds, and this might be explained by the increased tensile force applied on the wound with knee movement. This effect is magnified by the enhanced recovery protocols which aim to obtain high early range of movement. Most of the literature concluded that there is no difference between different closure methods. Objectives. We conducted an independent study comparing the complication rate associated with using barbed suture (Quill-Ethicon), Vicryl Rapide (polyglactins910-Ethicon) and skin staples for wound closure following TKA. Study Design & Methods. Retrospective study where the study group included all the patients admitted to our unit for elective primary knee arthroplasty in 2015, we excluded patients admitted for partial knee arthroplasty, revision knee arthroplasty or arthroplasty for treatment of acute trauma due to the relatively higher complication rates. All the patients notes were reviewed to identify wound related problems such as wound dehiscence, wound infection and delayed healing (defined as delayed wound healing more than 6 weeks). Results. 327 patients were included in this study; 151 in Quill group, 99 in staples group and 77 in the last group where the wound closed with Rapide. We identified 9 (5.9%) cases of wound dehiscence in the Quill group, 3 cases of wound dehiscence in each of other two groups (3.8%) with Rapide and (3%) with staples. On the other hand superficial wound infection was higher with staples with 6 (6%) cases of wound infection compared to the other groups, wound infection occurred in 2 patients (2.5%) with Rapide and 5 patients (3.3%) in the Quill”s group. Most of the delayed wound healing happened after using Quill where it is reported in 5 patients (3.3%) and the lowest was in staples group with 1 patient (1%) and slightly higher percentage in Rapide group 2 patients (2.5%). The total figure of wound related problems was the highest in Quill”s group with 19 reported cases (12.5%), lower in staples” group with 10 cases (1.1%) and the lowest in Rapide”s group with 7 cases (9%). Conclusions. Our study showed different results to the reported literature suggesting that each closure method has its own advantages and disadvantages. Quill is quick, knotless and absorbable but on the other side it is significantly more expensive than other alternatives and it is associated with the highest complication rates. On the other hand Rapide is cheap absorbable alternative with the lowest percentage of wound problems but on the negative side it is time consuming. Finally staples method is the quickest, relatively cheap and rarely associated with wound dehiscence but it is not absorbable which might cause inconvenience to patients

Introduction. We describe a novel single incision approach and its safety in the largest reported series of Lisfranc injuries to date. Via separate subcutaneous windows it is possible to access the medial three rays of the foot for bridge plating, without the concern of narrow skin bridges between multiple incisions. Methods. A retrospective review identified all 150 patients who underwent a Lisfranc ORIF via the modified dorsal approach at the Royal Melbourne Hospital between January 2011 and June 2016. All patients were operated by a single surgeon. Removal of metalwork (ROM) was routinely undertaken at six months post-operatively via the same incision. Medical recored were reviewed to record patient demographics, mechanism of injury and surgical details. Outpatient notes were reviewed to identify wound-related complications including; delayed wound healing, superficial infection, wound dehiscence, deep infection, complex regional pain syndrome (CRPS), neuroma and impaired sensation. Median follow-up was 1012 days (range 188–2141). Results. Median age was 37 years (19–78). 110 (73%) patients were male. Mechanism of injury was: motor vehicle accident (37%), motor bike accident (19%) and fall (18%). 24 (16%) injuries were open, 5 of which required soft tissue reconstruction at the primary surgery. A total of 34 wound related complications occurred (22%); superficial infection (14), delayed wound healing (7), wound dehiscence (5), CRPS (4), impaired sensation (3), neuroma (1). Re-operation was necessary in the 5 patients who experienced wound dehiscence; 4 requiring split skin grafts and 1 requiring a free flap. Crush injuries were 10 times more likely to have wound complications than those sustained in motor vehicle accidents. Patients undergoing ROM were more likely to have wound complications than those who did not. Conclusion. The modified dorsal approach using subcutaneous windows to access the midfoot joints offers a viable alternative to existing approaches

Aims. To evaluate the perioperative complications associated with total en bloc spondylectomy (TES) in patients with spinal tumours, based on the extent and level of tumour resection. Methods. In total, 307 patients who underwent TES in a single centre were reviewed retrospectively. There were 164 male and 143 female patients with a mean age at the time of surgery of 52.9 years (SD 13.3). A total of 225 patients were operated on for spinal metastases, 34 for a malignant primary tumour, 41 for an aggressive benign tumour, and seven with a primary of unknown origin. The main lesion was located in the thoracic spine in 213, and in the lumbar spine in 94 patients. There were 97 patients who underwent TES for more than two consecutive vertebrae. Results. Major and minor perioperative complications were observed in 122 (39.7%) and 84 (27.4%) patients respectively. The breakdown of complications was as follows: bleeding more than 2,000 ml in 60 (19.5%) patients, hardware failure in 82 (26.7%), neurological in 46 (15.0%), surgical site infection in 23 (7.5%), wound dehiscence in 16 (5.2%), cerebrospinal fluid leakage in 45 (14.7%), respiratory in 52 (16.9%), cardiovascular in 11 (3.6%), digestive in 19 (6.2%)/ The mortality within two months of surgery was four (1.3%). The total number of complications per operation were 1.01 (SD 1.0) in the single vertebral resection group and 1.56 (SD 1.2) in the group with more than two vertebral resections. Cardiovascular and respiratory complications, along with hardware failure were statistically higher in the group who had more than two vertebrae resected. Also, in this group the amount of bleeding in patients with a lumbar lesion or respiratory complication in patients with a thoracic lesion, were statistically higher. Multivariate analysis showed that using a combined anterior and posterior approach, when more than two vertebral resections were significant independent factors. Conclusion. The characteristics of perioperative complications after TES were different depending on the extent and level of the tumour resection. In addition to preoperative clinical and pathological factors, it is therefore important to consider these factors in patients who undergo en bloc resection for spinal tumours.

Aim. Decubitus ulcers are found in approximately 4.7% of hospitalized patients, with a higher prevalence (up to 30%) among those with spinal cord injuries. These ulcers are often associated with hip septic arthritis and/or osteomyelitis involving the femur. Girdlestone resection arthroplasty is a surgical technique used to remove affected proximal femur and acetabular tissues, resulting in a substantial defect. The vastus lateralis flap has been employed as an effective option for managing this dead space. The aim of this study was to evaluate the long-term outcomes of this procedure in a consecutive series of patients. Method. A retrospective single-center study was conducted from October 2012 to December 2022, involving 7 patients with spinal cord injuries affected by chronic severe septic hip arthritis and/or femoral head septic necrosis as a consequence of decubitus ulcers over trochanter area. All patients underwent treatment using a multidisciplinary approach by the same surgical team (orthopedic and plastic surgeons) along with infectious disease specialists. The treatment consisted of a one-stage procedure combining Girdlestone resection arthroplasty with unilateral vastus lateralis flap reconstruction, alongside targeted antibiotic therapy. Complications and postoperative outcomes were assessed and recorded. The mean follow-up period was 8 years (range 2-12). Results. Of the 7 patients, 5 were male and 2 were female, with a mean age of 50.3 years at the time of surgery. Minor wound dehiscence occurred in 28.6% of the flap sites, and 2 patients required additional revisional procedures—one for hematoma and the other for bleeding. There were no instances of flap failure, and complete wound healing was achieved in an average of 32 days (range 20-41), with the ability to load over the hip area. No cases of infection recurrence or relapse were observed. Conclusions. An aggressive surgical approach is strongly recommended for managing chronic hip septic arthritis or proximal femur osteomyelitis in patients with spinal cord injuries. A single-stage procedure combining Girdlestone resection arthroplasty with immediate vastus lateralis muscle flap reconstruction proves to be an effective strategy for dead space management and localized antibiotic delivery through the vastus muscle, giving reliable soft tissue coverage around the proximal femur to avoid the recurrence of pressure ulcers. The implementation of a standardized multidisciplinary protocol contributes significantly to the success of reconstruction efforts

This large UK multicentre study evaluates clinical outcomes and identifies factors associated with local complication following PFR for non-oncological conditions. 132 patients across four UK centres underwent PFR from 01/08/2004-28/03/2023 with median follow-up of 1.9 (Q10.5-Q34.2) years. 75 (56.8%) patients were female and the mean age was 74.0 (SD 11.7) years. 103 (78%) patients had Charleston Comorbidity Index ≥3. ASA class was III or IV in 66.6%. Indications were infected revision (39, 29.5%), periprosthetic fracture (36, 27.3%), acute trauma (30, 22.7%), aseptic revision (17, 12.9%), failed trauma (nine, 6.8%) and complex primary arthroplasty (one, 0.8%). The primary outcome was the local complication rate. Secondary outcomes were systemic complications, reoperation and mortality rates. Comparisons were made with t-tests and Chi2 tests to investigate patient and surgical factors associated with local complication. Statistical significance was p<0.05. There were 37(28.0%) local complications. These were 18 (13.6%) dislocations, eight (6.1%) prosthetic joint infections, four (3.0%) haematomas, three (2.3%) superficial infections, one (0.8%) wound dehiscence, one (0.8%) sciatic nerve palsy and one (0.8%) femoral perforation. Dislocation mostly occurred in conventional articulations (12, 9.1%) followed by dual-mobility cups (three, 2.3%), constrained cups (two, 1.5%) and hemiarthroplasty (one, 0.8%). Median time to local complication was 30 (Q14-Q3 133) days. Seven (5.3%) patients developed a systemic complication. Thirty-three (25.0%) patients underwent reoperation. Thirty-day and one-year mortality rates were 3.8% and 12.1%, respectively. Longer surgical waiting times (7.9 \[SD 16.9) versus 2.6 \[SD 4.4\] days, p<0.001) and longer operating times (212.5 \[SD 71.8\] versus 189.4 \[SD 59.3\] mins, p=0.0450) were associated with local complication. Due to its high complication rate, PFR should be a salvage option when performed for non-oncological indications. Conventional articulations should be avoided. PFR should be delivered in a timely manner and ideally as dual-consultant cases to reduce operating time

Introduction. Cerament, a bioresorbable hydroxyapatite and calcium sulfate cement, is known to be used as a bone-graft substitute in traumatic bone defect cases. However, its use in open fractures has not previously been studied. Materials and Methods. Retrospective, single-centre review of cases between November 2016 and February 2021. Open fractures were categorised according to the Orthopaedic Trauma Society classification (OTS). Cases were assessed for union, time to union, and associated post-operative complications. Results. Twenty-four patients were identified. Fifteen cases were classified as OTS simple open fractures, and nine cases were complex open fractures requiring soft tissue reconstruction. Four cases were lost to follow-up. Four cases had limited follow-up beyond 6 months but showed evidence of progressive radiographic union. Of the remaining 16 cases, eight cases (50%) went on to union with a mean time to union of 6.7 months (5 to 12 months). Persistent non-union remained in six cases (38%). Two cases required return to theatre due to an infected skin graft and wound dehiscence respectively. One case had the complication of persistent weeping of Cerament from the wound. This self-resolved within two weeks. Limitations of this case series include the lack of complete follow-up in eight patients (33%) and the lack of patient reported outcome measures. Conclusions. Cerament can be a useful adjunct in managing open fractures. However, it should be noted there is a high rate of non-union which may be reflective of the significant morbidity associated with open fractures with structural bone defects

Introduction. Amputation or disarticulation is a reliable option for management of severe foot deformities and limb-length discrepancies, the surgical restoration of which are unpredictable or unfavourable. Of the various surgeries involving foot ablation, Syme's amputation is preferred for congenital deformities as it provides a growing, weight bearing stump with proprioception and cushioning. Materials and Methods. We reviewed data of all children who underwent Syme's amputation over the past 13 years at our institution. Surgical technique followed the same principles for Syme's but varied with surgeons. Results. Ten boys and ten girls, with an average age of 18 months and average follow up of 70 months were included in the study. The most common indication was fibular hemimelia. Wound complications were reported in three children, phantom pain in one, heel pad migration in two. None had wound dehiscence, flap necrosis, stump overgrowth, or calcaneal regrowth. None of this required surgical intervention. One child required an amputation at a higher-level secondary to a congenital malformation of nervous tissue in the affected leg. Prosthetic compatibility was 94.7 % and none used mobility aids. Six children participated in sports. Conclusions. Syme amputation is a safe and potentially advantageous procedure in children, with a low incidence of complications to offer patients with non-salvageable foot conditions. It offers good prosthetic use with minimal risk of complications and can offer patients a functional solution with only one surgical intervention throughout their childhood

Introduction and Aims: The use of the triradiate approach has been associated with high rates of wound dehiscence, wound infection and significant heterotopic ossification. This approach has been the favoured extensile exposure at the Vancouver General Hospital for many years. We will review the outcomes of the use of this approach in the treatment of acetabular fractures. Method: Patients were identified from the database at Vancouver General Hospital who had their acetabular fractures treated through a triradiate approach from the period January 1989 through to December 2001. Patients with a delay of greater than three weeks from injury were excluded. A retrospective review of the hospital and out-patient records and all available radiographs was performed. Patients were contacted to determine if they required any further surgery and to assess their current functional status with appropriate outcome scores. Patients were also invited to undergo repeat radiographic assessment. Results: Of a total of 407 acetabular fractures treated surgically, 152 open reductions were performed through the triradiate approach. The average age of these patients was 38 years and 114 (75%) of these were male. Patients referred from other hospitals totalled 128 (84%). Wound outcomes were known in 138 cases. Wound complications included five cases of wound dehiscence, of which four resolved with no undue effects. There were three cases of superficial wound infection and five cases of deep wound infection. Two of the patients with deep wound infection had sustained compound acetabular injuries and a further two had significant risk factors for infection (septicaemia from chest infection and significant soft tissue necrosis). Trochanteric osteotomy was performed in 139 (91%) cases. There were only two cases of trochanteric non-union in this series, however 21 cases required removal of painful trochanteric screws. With respect to heterotopic ossification, there was a 15% Broker III/IV incidence. In this group, the injury severity scores were higher, there was a greater delay to surgery and there was a greater need for mechanical ventilation due to multiple injuries. In the group, 24 hip reconstructions were required over the period. Conclusion: In our centre, we found a low rate of wound dehiscence and deep wound infection associated with the triradiate approach in the treatment of acetabular fractures. Both open acetabular fractures developed deep infection. Trochanteric irritation was a problem in a number of the patients. The rate of significant hetero-topic ossification was low

Aim. The optimal surgical approach for patients hospitalized for moderate to severe septic bursitis is not known, and there have been no randomized trials of a one-stage compared with a two-stage (i.e., bursectomy, followed by closure in a second procedure) approach. Thus, we performed a prospective, non-blinded, randomized study of adult patients hospitalized for an open bursectomy. Method. Patients were randomized 1:1 to a one-stage vs. a two-stage surgical approach. All patients received postsurgical oral antibiotic therapy for 7 days. These are the final results of the prospective study registered at ClinicalTrials (NCT01406652). Results. Among 164 enrolled patients, 130 had bursitis of the elbow and 34 of the patella. The surgical approach used was one-stage in 79 and two-stage in 85. The two groups were balanced with regards to sex, age, causative pathogens, levels of serum inflammatory markers, co-morbidities, and cause of bursitis. Overall, there were 22 treatment failures: 8/79 (10%) in the one-stage arm and 14/85 (16%) in the two-stage arm (Pearson-χ2-test; p=0.23). Recurrent infection was caused by the same pathogen a total of 7 patients (4%), and by a different pathogen in 5 episodes (3%). The incidence of infection recurrence was not significantly different between those in the one- vs. two-stage arms (6/79 vs. 8/85; χ2-test: p=0.68). In contrast, outcomes were better in the one- vs. two-stage arm for wound dehiscence (2/79[3%] vs. 10/85[12%]; p=0.02), median length of hospital stay (4.5 vs. 6 days), nurses’ workload (605 vs. 1055 points) and total costs (6,881 vs. 11,178 Swiss francs) (all p<0.01). Conclusions. For adult patients with moderate to severe septic bursitis requiring hospital admission, bursectomy with primary closure, together with 7 days of systemic antibiotic therapy, was safe, resource-saving and effective. Using a two-stage approach did not reduce the risk of infectious recurrence, and may be associated with a higher rate of wound dehiscence than the one-stage approach

Introduction. Intraarticular calcaneal fractures often need open reduction and internal fixation (ORIF) with plate osteosynthesis. The wound complication is one of the common problems encountered following this and affects the outcome adversely. Our study was done to assess how far postoperative slab/cast can avert wound complications. Methods. Out of 42 patients with unilateral intraarticular calcaneal fractures, 20 were offered postoperative slab/cast and this was continued for six weeks. The remaining 22 patients were not offered any plaster. All patients were followed-up for two years. Results. The incidence of wound dehiscence was 2 in the plaster group as well as 8 in the non-plaster group and this was statistically significant (p = 0.02). Also, significantly lower heel widening was reported in the plaster group (p = 0.03). Although, there was no significant difference in the patient-reported outcome (Maryland Foot Score) and the incidence of pain between the two groups, the occurrence of neurological deficit following surgery and the postoperative range of movements were comparable in these two groups. Conclusion. Thus, it may be concluded that postoperative plaster application for the initial six weeks could be a low-cost yet effective way to reduce wound complications following plate osteosynthesis in intraarticular calcaneal fractures

Aims. The aim of this study was to describe the technique of distraction osteogenesis followed by arthrodesis using internal fixation to manage complex conditions of the ankle, and to present the results of this technique. Patients and Methods. Between 2008 and 2014, distraction osteogenesis followed by arthrodesis using internal fixation was performed in 12 patients with complex conditions of the ankle due to trauma or infection. There were eight men and four women: their mean age was 35 years (23 to 51) at the time of surgery. Bone healing and functional recovery were evaluated according to the criteria described by Paley. Function was assessed using the ankle-hindfoot scale of the American Orthopedic Foot and Ankle Society (AOFAS). Results. A solid fusion of the ankle and eradication of infection was achieved in all patients. A mean lengthening of 6.1 cm (2.5 to 14) was achieved at a mean follow-up of 25.2 months (14 to 37). The mean external fixation index (EFI) was 42 days/cm (33.3 to 58). The function was judged to be excellent in six patients and good in six patients. Bone results were graded as excellent in ten patients and good in two patients. The mean AOFAS score was 37.3 (5 to 77) preoperatively and 75.3 (61 to 82) at the final follow-up. Minor complications, which were treated conservatively, included pain, pin-tract infection, loosening of wires, and midfoot stiffness. Major complications, which were treated surgically included grade V pin-tract infection with inflammation and osteolysis, poor consolidation of the regenerate bone, and soft-tissue invagination. The reoperations required to treat the major complications included the exchange of pins and wires, bone grafting and invagination split surgery. Conclusion. The technique of distraction osteogenesis followed by arthrodesis using internal fixation is an effective form of treatment for the management of complex conditions of the ankle. It offers a high rate of union, an opportunity to remove the frame early, and a reduced EFI without infection or wound dehiscence. Cite this article: Bone Joint J 2018;100-B:755–60

Since its approval by the FDA two decades ago, Negative Pressure Wound Therapy (NPWT) has become a valuable asset in the management of open fractures with significant soft tissue damage as those seen in high velocity gunshot injuries. These lesions are often associated with grossly contaminated wounds and require a prompt and effective approach. Wound dehiscence and surgical site infection are two of the most common post-operative complications, with poor results when treated with standard gauze dresses. NPTW comes as a legitimate resource promoting secondary intention healing through increased granulation and improved tissue perfusion, as well as continuous local wound drainage preventing bacterial growth and further infection. Recent evidence-based guidelines are still limited for use of NPWT in the treatment of Gustilo-Anderson type IIIB open fractures and there are few cases in literature reporting the management of upper extremity injuries. We present and discuss a successful case of a type IIIB open humeral fracture wound treated with NPWT. A 38-years-old male was admitted to the Emergency Room with a type IIIB open humeral fracture as a result of a gunshot with extensive soft tissue damage. IV antibiotic therapy was promptly started followed by surgical stabilization by intramedullary nailing with primary wound closure. The patient presented an early surgical site infection with wound dehiscence requiring secondary debridement with poor subsequent healing and deficient soft tissue coverage. After ineffective 28 days of standard gauze dresses we started NPWT. NPTW was applied using foam coverage over the dehiscence area with visible results after 13 days and complete granulation of the skin defect by the 28th day. The wound healed completely after 14 weeks of NPWT. The fracture evolved into a painless pseudarthrosis revealing an excellent functional recovery and an acceptable aesthetic result. NPTW is a valuable, effective, and well tolerated resource in the treatment of open fractures with extensive soft tissue damage such as Gustilo-Anderson type IIIB fractures. It should be considered not just as a salvage procedure but as well as a primary option especially in grossly contaminated wounds. No benefits in any form have been received from a commercial party
