The Covid-19 pandemic restricted access to elective arthroplasty theatres. Consequently, there was a staggering rise in waiting times for patients awaiting total hip arthroplasty (THA). Concomitantly, rapidly destructive osteoarthritis (RDOA) incidence also increased. Two cohorts of patients were reviewed: patients undergoing primary THA, pre-pandemic (December 2017-December 2018) and patients with RDOA (ascertained by dual consultant review of pre-operative radiographs) undergoing THA after the pandemic started (March 2020 – March 2022). There were 236 primary THA cases in the pre-pandemic cohort. Out of the 632 primary THA cases post-pandemic, 186 cases (29%) had RDOA. Within this RDOA cohort, the pre-operative mean OHS, EQ5D3L and EQVAS (12.7, 10.5 and 57.6 respectively) were all poorer than in the pre-pandemic population (18.3, 9.4 and 66.7 respectively) (p<0.05). There was no significant difference between the RDOA and pre-pandemic cohort in Patient Reported Outcome Measures (PROMS) at 12 months, perhaps due to their ceiling effect. Within the RDOA cohort, 7 cases required acetabular augments, 1 of which also required femoral shortening. The rate of intra-operative fracture, dislocation, infection, return to theatre, and revision were 2.2%, 2.7%, 4.3%, 3.8% and 2.2% respectively, greater than those reported in the literature. No fractures nor dislocations occurred in robot assisted arthroplasties. With ever increasing waiting lists, RDOA prevalence will continue to rise. Increased surgical challenges and potential use of additional implants generated by its presence excludes these patients from waiting list initiative pathways, potentiating the complexity of the operative procedure. Going forwards, the economic burden and training implications must be considered

The aim was to report operative complications, radiographic and patient-reported outcomes following lateral tibial plateau fracture fixation augmented with calcium phosphate cement (CPC). From 2007–2018, 187 patients (median age 57yrs [range 22–88], 63% female [n=118/187]) with a Schatzker II/III fracture were retrospectively identified. There were 103 (55%) ORIF and 84 (45%) percutaneous fixation procedures. Complications and radiographic outcomes were determined from outpatient records and radiographs. Long-term follow-up was via telephone interview. At a median of 6 months (range 0.1–138) postoperatively, complications included superficial peroneal nerve injury (0.5%, n=1/187), infection (6.4%, n=12/187), prominent metalwork (10.2%, n=19/187) and post-traumatic osteoarthritis (PTOA; 5.3%, n=10/187). The median postoperative medial proximal tibial angle was 89o (range 82–107) and posterior proximal tibial angle 82o (range 45–95). Three patients (1.6%) underwent debridement for infection and 27 (14.4%) required metalwork removal. Seven patients (4.2%) underwent total knee replacement for PTOA. Sixty percent of available patients (n=97/163) completed telephone follow-up at a median of 6yrs (range 1–13). The median Oxford Knee Score was 42 (range 3–48), Knee injury and Osteoarthritis Outcome Score 88 (range 10–100), EuroQol 5-Dimension score 0.812 (range −0.349–1.000) and Visual Analogue Scale 75 (range 10–100). There were no significant differences between ORIF and percutaneous fixation in patient-reported outcome (all p>0.05). Fixation augmented with CPC is safe and effective for lateral tibial plateau fractures, with a low complication rate and good long-term knee function and health-related quality of life. Percutaneous fixation offers a viable alternative to ORIF with no detriment to patient-reported outcome

The surgical care of extra-articular distal tibial fractures remains controversial. This study looks at the radiological outcomes of distal tibial fractures treated with either a direct medial or anterolateral plate, with or without plating of the fibula, to assess the outcome and complications associated with these 2 approaches. This is a retrospective review of 80 patients with distal tibial extra-articular fractures, treated with an open reduction and plating, between 2008 and 2019 at Glasgow Royal Infirmary. Case notes and x-rays were reviewed. Of those tibial fractures fixed with only a medial plate, 78% united (28/36), 5% (2/36) had a non-union and 17% (6/36) a malunion. In the group treated with a combination of medial tibial and fibular plating, the figures were; 71% (15/21), 19% (4/21) and 10% (2/21). However, in the group treated with anterolateral plating of the tibia alone, only 53% (8/15) united, with a 20% (3/15) non-union and 13% (2/15) malunion rate. Additionally in this group, there were 2 patients (13%) with loss of fracture reduction within the first two months of fracture fixation, requiring revision surgery. Interestingly, of the 8 patients treated with anterolateral tibial and fibular plating, 88% (7/8) showed full union and only one (12%) had a non-union, with no malunions is this group. It would appear that medial tibial and a combination of medial tibial and fibular plating, have superior outcomes compared to anterolateral plating. Results suggest, if anterolateral plating is done, this should be augmented by fixation of the fibular fracture as well

Introduction. Modular tantalum augments have been introduced to manage severe bone defects in hip and knee revision surgery. The porous surfaces of tantalum augments are intended to enhance osseointegration and a number of studies have documented their excellent biocompatibility. However, the characteristics of tantalum augment osseointegration on human ex vivo specimens from re-revision procedures have not been reported so far. Methods. Out of a total number of 324 hip and knee revisions with a tantalum augment performed in our institution between 2007 and 2010 four patients had to be re-revised at a mean followup time of 15 months. The causes for re-revision were a periprosthetic acetabular fracture in one, a loosening of a tibial component in one and periprosthetic hip infections in two cases. To characterize osseointegration of the tantalum augments, they were removed during revision surgery and subjected to undecalcified processing. All specimens were analysed by contact radiography, histology (toluidine blue, von Kossa) and quantitative histomorphometry. Results. In all specimens trabecular ingrowth was apparent along the former bone-augment-interface. The depth of bone ingrowth into the porous microarchitecture of the augments reached up to 2000 μm. Thin-section analysis revealed scattered and partially mineralized bone forming units within the interior of the augments. Conclusions. To the best of our knowledge this is the first histomorphometric analysis on the osseointegration of tantalum augments in human ex vivo specimens. In the presented series porous tantalum showed excellent osteoconductive characteristics on the histological level. These early ex vivo histological findings are promising, but structural analysis of later re-revision cases is needed

The augmentation of fixation with bone cement is increasingly being used in the treatment of severe osteoporotic fractures. We investigated the influence of bone quality on the mechanics of augmentation of plate fixation in a distal femoral fracture model (AO 33 A3 type). Eight osteoporotic and eight non-osteoporotic femoral models were randomly assigned to either an augmented or a non-augmented group. Fixation was performed using a locking compression plate. In the augmented group additionally 1 ml of bone cement was injected into the screw hole before insertion of the screw. Biomechanical testing was performed in axial sinusoidal loading. Augmentation significantly reduced the cut-out distance in the osteoporotic models by about 67% (non-augmented mean 0.30 mm (. sd. 0.08) vs augmented 0.13 mm (. sd. 0.06); p = 0.017). There was no statistical reduction in this distance following augmentation in the non-osteoporotic models (non-augmented mean 0.15 mm (. sd. 0.02) vs augmented 0.15 mm (. sd. 0.07); p = 0.915). In the osteoporotic models, augmentation significantly increased stability (p = 0.017). Cite this article: Bone Joint J 2013;95-B:1406–9

Aims

Patient decision aids have previously demonstrated an improvement in the quality of the informed consent process. This study assessed the effectiveness of detailed written patient information, compared to standard verbal consent, in improving postoperative recall in adult orthopaedic trauma patients.

Methods

This randomized controlled feasibility trial was conducted at two teaching hospitals within the South Eastern Sydney Local Health District. Adult patients (age ≥ 18 years) pending orthopaedic trauma surgery between March 2021 and September 2021 were recruited and randomized to detailed or standard methods of informed consent using a random sequence concealed in sealed, opaque envelopes. The detailed group received procedure-specific written information in addition to the standard verbal consent. The primary outcome was total recall, using a seven-point interview-administered recall questionnaire at 72 hours postoperatively. Points were awarded if the participant correctly recalled details of potential complications (maximum three points), implants used (maximum three points), and postoperative instructions (maximum one point). Secondary outcomes included the anxiety subscale of the Hospital and Anxiety Depression Scale (HADS-A) and visual analogue scale (VAS) for pain collected at 24 hours preoperatively and 72 hours postoperatively. Additionally, the Patient Satisfaction Questionnaire Short Form (PSQ-18) measured satisfaction at 72 hours postoperatively.


Aims

Ankle fracture fixation is commonly performed by junior trainees. Simulation training using cadavers may shorten the learning curve and result in a technically superior surgical performance.

Methods

We undertook a preliminary, pragmatic, single-blinded, multicentre, randomized controlled trial of cadaveric simulation versus standard training. Primary outcome was fracture reduction on postoperative radiographs.

Aims

The purpose of this study was to develop a convolutional neural network (CNN) for fracture detection, classification, and identification of greater tuberosity displacement ≥ 1 cm, neck-shaft angle (NSA) ≤ 100°, shaft translation, and articular fracture involvement, on plain radiographs.

Methods

The CNN was trained and tested on radiographs sourced from 11 hospitals in Australia and externally validated on radiographs from the Netherlands. Each radiograph was paired with corresponding CT scans to serve as the reference standard based on dual independent evaluation by trained researchers and attending orthopaedic surgeons. Presence of a fracture, classification (non- to minimally displaced; two-part, multipart, and glenohumeral dislocation), and four characteristics were determined on 2D and 3D CT scans and subsequently allocated to each series of radiographs. Fracture characteristics included greater tuberosity displacement ≥ 1 cm, NSA ≤ 100°, shaft translation (0% to < 75%, 75% to 95%, > 95%), and the extent of articular involvement (0% to < 15%, 15% to 35%, or > 35%).

Aims. To evaluate the outcomes of cemented total hip arthroplasty (THA) following a fracture of the acetabulum, with evaluation of risk factors and comparison with a patient group with no history of fracture. . Patients and Methods. Between 1992 and 2016, 49 patients (33 male) with mean age of 57 years (25 to 87) underwent cemented THA at a mean of 6.5 years (0.1 to 25) following acetabular fracture. A total of 38 had undergone surgical fixation and 11 had been treated non-operatively; 13 patients died at a mean of 10.2 years after THA (0.6 to 19). Patients were assessed pre-operatively, at one year and at final follow-up (mean 9.1 years, 0.5 to 23) using the Oxford Hip Score (OHS). Implant survivorship was assessed. An age and gender-matched cohort of THAs performed for non-traumatic osteoarthritis (OA) or avascular necrosis (AVN) (n = 98) were used to compare complications and patient-reported outcome measures (PROMs). Results. The mean time from fracture to THA was significantly shorter for patients with AVN (2.2 years) or protrusio (2.2 years) than those with post-traumatic OA (9.4 years) or infection (8.0 years) (p = 0.03). Nine contained and four uncontained defects were managed with autograft (n = 11), bulk allograft (n = 1), or trabecular metal augment (n = 1). Initial fracture management (open reduction and internal fixation or non-operative), timing of THA (> /< one year), and age (> /< 55 years) had no significant effect on OHS or ten-year survival. Six THAs were revised at mean of 12 years (5 to 23) with ten-year all-cause survival of 92% (95% confidence interval 80.8 to 100). THA complication rates (all complications, heterotopic ossification, leg length discrepancy > 10 mm) were significantly higher following acetabular fracture compared with atraumatic OA/AVN and OHSs were inferior: one-year OHS (35.7 versus 40.2, p = 0.026); and final follow-up OHS (33.6 versus 40.9, p = 0.008). . Conclusion . Cemented THA is a reasonable option for the sequelae of acetabular fracture. Higher complication rates and poorer PROMs, compared with patients undergoing THA for atraumatic causes, reflects the complex nature of these cases.

Aims

The aim of this study was to report the outcomes of patients with severe open fractures of the lower limb in the five years after they took part in the Wound management for Open Lower Limb Fracture (WOLLF) trial.

Methods

The WOLLF trial compared standard dressings to negative pressure wound therapy (NPWT) applied at the end of the first surgical wound debridement, and patients were followed-up for 12 months. At 12 months, 170 of the original 460 participants agreed to take part in this medium-term follow-up study. Patients reported their Disability Rating Index (DRI) (0 to 100, where 100 is total disability) and health-related quality of life (HRQoL) using the EuroQol five-dimension three-level health questionnaire (EQ-5D-3L) annually by self-reported questionnaire. Further surgical interventions related to the open fracture were also recorded.


Aims

Our objective was to conduct a systematic review and meta-analysis, to establish whether differences arise in clinical outcomes between autologous and synthetic bone grafts in the operative management of tibial plateau fractures.

Methods

A structured search of MEDLINE, EMBASE, the online archives of Bone & Joint Publishing, and CENTRAL databases from inception until 28 July 2021 was performed. Randomized, controlled, clinical trials that compared autologous and synthetic bone grafts in tibial plateau fractures were included. Preclinical studies, clinical studies in paediatric patients, pathological fractures, fracture nonunion, or chondral defects were excluded. Outcome data were assessed using the Risk of Bias 2 (ROB2) framework and synthesized in random-effect meta-analysis. The Preferred Reported Items for Systematic Review and Meta-Analyses guidance was followed throughout.

Systemic antibiotics reduce infection in open fractures. Local delivery of antibiotics can provide higher doses to wounds without toxic systemic effects. This study investigated the effect on infection of combining systemic with local antibiotics via polymethylmethacrylate (PMMA) beads or gel delivery. An established Staphylococcus aureus contaminated fracture model in rats was used. Wounds were debrided and irrigated six hours after contamination and animals assigned to one of three groups, all of which received systemic antibiotics. One group had local delivery via antibiotic gel, another PMMA beads and the control group received no local antibiotics. After two weeks, bacterial levels were quantified. . Combined local and systemic antibiotics were superior to systemic antibiotics alone at reducing the quantity of bacteria recoverable from each group (p = 0.002 for gel; p = 0.032 for beads). There was no difference in the bacterial counts between bead and gel delivery (p = 0.62). . These results suggest that local antibiotics augment the antimicrobial effect of systemic antibiotics. Although no significant difference was found between vehicles, gel delivery offers technical advantages with its biodegradable nature, ability to conform to wound shape and to deliver increased doses. Further study is required to see if the gel delivery system has a clinical role. Cite this article: Bone Joint J 2015;97-B:1423–7

Management of irreparable rotator cuff tears is challenging and controversial. Surgeons have been utilising biological tissue scaffolding to augment repairs, but there are concerns regarding viability and function. We wished to investigate this viability and clinical outcome in a small group of patients. All procedures were performed by a single surgeon over a three-year period. Inclusion criteria were patients with large cuff tears and failure of non-operative treatment. Exclusion criteria were patients with glenohumeral arthritis and where cuff repair could not be successfully performed. Open rotator cuff repair followed by augmentation with Graft Jacket® Regenerative Tissue Matrix (Wright Medical) was performed in all patients. A structured cuff repair physiotherapy protocol was then followed. Follow-up was at six months and at minimum twenty-four months post-operatively where Constant scores (CS) and Oxford Shoulder scores (OSS) were noted and a repeat ultrasound performed. Fourteen patients underwent the procedure. No patient was lost to follow-up. There were seven males and seven females with a mean age of 63 years (range 31–77). At minimum twenty-four month follow-up, thirteen patients had flexion and abduction above 90 degrees and symmetrical external rotation. Mean CS was 81 (range 70–91) and mean OSS was 46 (range 41–48). Shoulder ultrasound revealed an intact Graft Jacket® in all thirteen patients. The final patient had lower functional movement and lower CS (34) and OSS (25) and ultrasound identified a re-rupture. This study indicates that augmentation of large rotator cuff repairs with biological tissue scaffolding is a viable option and has good functional results


Aims

This study sought to compare the rate of deep surgical site infection (SSI), as measured by the Centers for Disease Control and Prevention (CDC) definition, after surgery for a fracture of the hip between patients treated with standard dressings and those treated with incisional negative pressure wound therapy (iNPWT). Secondary objectives included determining the rate of recruitment and willingness to participate in the trial.

Methods

The study was a two-arm multicentre randomized controlled feasibility trial that was embedded in the World Hip Trauma Evaluation cohort study. Any patient aged > 65 years having surgery for hip fracture at five recruitment centres in the UK was considered to be eligible. They were randomly allocated to have either a standard dressing or iNPWT after closure of the wound. The primary outcome measure was deep SSI at 30 and 90 days, diagnosed according to the CDC criteria. Secondary outcomes were: rate of recruitment; further surgery within 120 days; health-related quality of life (HRQoL) using the EuroQol five-level five-dimension questionnaire (EQ-5D-5L); and related complications within 120 days as well as mobility and residential status at this time.

In fractures electrical currents generated by piezoelectric and junctional diode effects initiate and augment healing. Conductive fixators may interfere with these currents causing delayed/nonunion which can be avoided by non conductive fixators, facilitating osteosynthesis. Null hypothesis of no difference and two tailed alternate hypothesis of any could be better was used. Impugn change in Electrical properties for demarcating union rate. Patients of Gustillo's grade I and II tibia fractures were randomised in conductive and non conductive fixator groups in a blinded manner. Electrical and clinico-radiological properties were compared every two weeks for 20 weeks, recoding magnitude and significant difference. Capacitance(p=0.03), Impedance(p=0.002), Inductance(p=0.01) and Reactance(p=0.02) are the electrical parameters which not only demarcated union rate but orchestrated diagnosis of fracture healing. In Non-conducting group, after removal of fixator at week 10, Local Tenderness was consistently absent, Rust Score was higher at week 18 and 20(p=0.01), absence of abnormal mobility was 58% higher and 100% at week 12(p < 0.05), Presence of weight bearing was higher from week 16(OR=15, p=0.03), presence of transmitted movement was 2.4 times higher at week 10(95% CI=0.17–34.93, p=0.52) and was 100% at week 14. Fractures heal at a faster rate if fixed by insulated non-conducting external fixators. Electrical parameters can be used to demarcate and monitor fracture healing

Aims

Infection after surgery increases treatment costs and is associated with increased mortality. Hip fracture patients have historically had high rates of methicillin-resistant Staphylococcus aureus (MRSA) colonization and surgical site infection (SSI). This paper reports the impact of routine MRSA screening and the “cleanyourhands” campaign on rates of MRSA SSI and patient outcome.

Methods

A total of 13,503 patients who presented with a hip fracture over 17 years formed the study population. Multivariable logistic regression was performed to determine risk factors for MRSA and SSI. Autoregressive integrated moving average (ARIMA) modelling adjusted for temporal trends in rates of MRSA. Kaplan-Meier estimators were generated to assess for changes in mortality.

Between July 2000 and December 2002, 263 consecutive patients across 5 surgical centers underwent to a revision surgery of a failed acetabular component in which TM acetabular components were used. There were 150 women and 113 men with a mean age of 69.5 years. The indication for acetabular revision was aseptic loosening in 186 cases (70.7%). Clinical evaluations were performed using the Harris hip score, the WOMAC and UCLA activity scale. Implant and screw position, polyethylene wear, radiolucent lines, gaps, and osteolysis were assessed. Preoperatively, acetabular bone deficiency was categorized using the classification of Paprosky et al. Statistical analysis was performed using nonparametric correlations. Standard life table was constructed, and the survival rate was calculated by means of Kaplan-Meier method. The overall mean follow-up was 73.6 months (range, 60–84 months), and no patient was lost to follow-up. The preoperative HHS rating improved from a mean of 43.6 ± 11.4 before revision, to a mean of 82.1 ± 10.7. None of the patients was re-revised for loosening. The cumulative prosthesis survival was 99.2% at 5 years. There was no correlation found between the various degrees of acetabular bony defect and the magnitude of clinical results (independent of pre-revision Paprosky grade). The use of component augments allowed us to minimize the volume of morsellized allograft used for defect repair. TM acetabular component demonstrates promising midterm results similar to those reported by other authors

We treated 19 patients with established nonunion of the radius and/or ulna by the excision of avascular bone and the grafting of blocks of corticocancellous bone from the iliac crest, augmented by rigid plate fixation under compression. This allowed early mobilisation, and bony union was achieved between three and 24 months after operation in all but one of the patients. The single failure was attributed to the excessive length of the defect (100 mm) and inadequate fixation

Posterolateral spinal fusion (PSLSF) in rabbits is a challenging model for bone substitutes because the transverse processes are extremely thin and the space to be filled with bone is greater than critical and meiopragic in terms of vascularity. Several investigators have shown beneficial effects of PRP in bone and soft-tissue healing processes. However, controversial results have been reported in clinical setting analysing the effectiveness of PRP. Aim of the present study was to test the effectiveness of PRP in experimental model of PLSF in rabbits. MATERIAL AND METHODS. 20 White females New Zeland Rabbits were used. Seven rabbits (Group 1) had PRP plus carrier on the right side (Group 1A) and plus carrier and fresh bone marrow on the left side (Group 1B). Seven rabbits (Group 2) had carrier alone on the right side (Group 2A) and carrier plus fresh bone marrow on the left side (Group 2B). Six rabbits (Group 3) had sham operation on both right and left sides. Animals were sacrificed 6 months after surgery and the lumbar spine submitted to radiolographic and histologic analysis. Vascular density (VD) was also assessed in the different zone of the grafted material. RESULTS. Radiographs showed a complete fusion in 83% of group 1A and in 83% of group 1B, and in 86% of group 2A and 2B. Pseudarthrosis or non union, was observed in 1 specimen of group 1B and 2A and in all specimens of group 3 (sham). In contrast to radiographic results, no specimen showed a complete bony bridge between the transverse processes on histologic analysis. VD was significantly greater in the periapophyseal compared to the interapophyseal region of the graft material. However, no significant difference was found in the VD between groups. CONCLUSIONS. In this study PRP alone, or augmented with fresh bone marrow, failed to induce a histologically proved bony fusion in the PLSF model. Factors which may influence the effectiveness of PRP should be further addressed before applying PRP in the clinical setting

The present study sought to assess the clinical and radiological results and long-term joint impact of different techniques of lateral ankle ligament reconstruction. Material and methods. A multicenter retrospective review was performed on 310 lateral ankle reconstructions, with a mean 13 years’ follow-up (minimum FU of 5 years with a maximum of 30). Male subjects (53%) and sports trauma (78%) predominated. Mean duration of instability was 92 months; mean age at surgery was 28 years. 28% of cases showed subtalar joint involvement. Four classes of surgical technique were distinguished: C1, direct capsulo-ligamentary repair; C2, augmented repair; C3, ligamentoplasty using part of the peroneus brevis tendon; and C4, ligamentoplasty using the whole peroneus brevis tendon. Clinical and functional assessment used Karlsson and Good-Jones-Livingstone scores; radiologic assessment combined centered AP and lateral views, hindfoot weight-bearing Méary views and dynamic views (manual technique, TelosR or self-imposed varus). Results. The majority of results (92%) were satisfactory. The mean Karlsson score of 90 [19–100] (i.e., 87% good and very good results) correlated with the subjective assessment, and did not evolve over time. Postoperative complications (20%), particularly when neurologic, were associated with poorer results. Control X-ray confirmed the very minor progression in osteoarthritis (2 %), with improved stability (88%); there was, however, no correlation between functional result and residual laxity on X-ray. Unstable and painful ankles showed poorer clinical results and more secondary osteoarthritis. Analysis by class of technique found poorer results in C4-type plasties and poorer control of laxity on X-ray in C1-type tension restoration. Discussion. The present series is the largest to be reported with so long a follow-up. We applied the same study criteria as in the present series to each article reviewed in the literature, in order to expose the compared results. The occurence of complex instability is noted. Conclusion. The present results confirm the interest 1) of lateral ankle ligamentoplasty in the management of instability and protection against secondary osteoarthritis, and 2) of precise lesion assessment (CT-scan/MRI) to adapt surgery to the ligamentary and associated lesions
