Aims. The management of a significant bony defect following excision
of a diaphyseal atrophic
The management of a significant bone defect following excision of a diaphyseal atrophic femoral non-union remains a challenge. Traditional bone transport techniques require prolonged use of an external fixator with associated complications. We present our clinical outcomes using a combined technique of acute femoral shortening, stabilised with a deliberately long retrograde intramedullary nail, accompanied by bifocal osteotomy compression and distraction osteogenesis to restore segment length utilising a temporary monolateral fixator. 9 patients underwent the ‘rail and nail’ technique for the management of femoral non-union. Distraction osteogenesis was commenced on the 6th post-operative day. Proximal locking of the nail and removal of the external fixator was performed approximately one month after length had been restored. Full weight bearing and joint rehabilitation was encouraged throughout. Consolidation was defined by the appearance of 3 from 4 cortices of regenerate on radiographs.Introduction
Method
In an interdisciplinary project involving electronic
engineers and clinicians, a telemetric system was developed to measure
the bending load in a titanium internal femoral fixator. As this
was a new device, the main question posed was: what clinically relevant
information could be drawn from its application? As a first clinical
investigation, 27 patients (24 men, three women) with a mean age
of 38.4 years (19 to 66) with
We reviewed 78 femoral and tibial nonunions treated between January 1992 and December 2003. Of these, we classified 41 in 40 patients as complex cases because of infection (22), bone loss (6) or failed previous surgery (13). The complex cases were all treated with Ilizarov frames. At a mean time of 14.1 months (4 to 38), 39 had healed successfully. Using the Association for the Study and Application of the Methods of Ilizarov scoring system we obtained 17 excellent, 14 good, four fair and six poor bone results. The functional results were excellent in 14 patients, good in 14, fair in two and poor in two. A total of six patients were lost to follow-up and two had amputations so were not evaluated for final functional assessment. All but two patients were very satisfied with the results. The average cost of treatment to the treating hospital was approximately £30 000 per patient. We suggest that early referral to a tertiary centre could reduce the morbidity and prolonged time off work for these patients. The results justify the expense, but the National Health Service needs to make financial provision for the reconstruction of this type of complex nonunion.
The paper present our results in application of new method for nonunion treatment of the femoral diaphysis. The internal fixator has been applied with 36 patients. Bone graft substitution is used with 11 (30,5%) patients. The method of placement and results of the work according to the modified system of the Karlstrom-Olerud method have been presented. Excellent condition was found with 25 (69,4%) patients, satisfactory with 8 (22,2%) and poor with 3 (8,3%) patients. Average healing time is 57 weeks. The method in which the internal fixator is applied provides complete stability of the nonunion and makes possible spontaneous-biological dinamization of the nonunion. It doesn’t damage the periosteal and medullary bone vascularization which favors healing process.
Periprosthetic femoral shaft fractures are a significant complication of total hip arthroplasty. Plate osteosynthesis with or without onlay strut allograft has been the mainstay of treatment around well-fixed stems. Nonunions are a rare, challenging complication of this fixation method. The number of published treatment strategies for periprosthetic
Introduction: The treatment of
We undertook a retrospective study of 50 consecutive patients (41 male, 9 female) with an infected nonunion and bone defect of the femoral shaft who had been treated by radical debridement and distraction osteogenesis. Their mean age was 29.9 years (9 to 58) and they had a mean of 3.8 (2 to 19) previous operations. They were followed for a mean of 5.9 years (2.0 to 19.0). The mean duration of the distraction osteogenesis was 24.5 months (2 to 39). Pin-track infection was observed in all patients. The range of knee movement was reduced and there was a mean residual leg-length discrepancy of 1.9 cm (0 to 8) after treatment. One patient required hip disarticulation to manage intractable sepsis. In all, 13 patients had persistant pain. Bony union was achieved in 49 patients at a mean of 20.7 months (12 to 35). Although distraction osteogenesis is commonly used for the treatment of infected
Total femoral arthroplasty (TFA) is a rare procedure used in cases of significant femoral bone loss, commonly from cancer, infection, and trauma. Low patient numbers have resulted in limited published work on long-term outcomes, and even less regarding TFA undertaken for non-oncological indications. The aim of this study was to evaluate the long-term clinical outcomes of all TFAs in our unit. Data were collected retrospectively from a large tertiary referral revision arthroplasty unit’s database. Inclusion criteria included all patients who underwent TFA in our unit. Preoperative demographics, operative factors, and short- and long-term outcomes were collected for analysis. Outcome was defined using the Musculoskeletal Infection Society (MSIS) outcome reporting tool.Aims
Methods
This observational cross-sectional study aimed to answer the following questions: 1) how has nonunion incidence developed from 2009 to 2019 in a nationwide cohort; 2) what is the age and sex distribution of nonunions for distinct anatomical nonunion localizations; and 3) how high were the costs for surgical nonunion treatment in a level 1 trauma centre in Germany? Data consisting of annual International Classification of Diseases (ICD)-10 diagnosis codes from German medical institutions from 2009 to 2019, provided by the Federal Statistical Office of Germany (Destatis), were analyzed. Nonunion incidence was calculated for anatomical localization, sex, and age groups. Incidence rate ratios (IRRs) were determined and compared with a two-sample z-test. Diagnosis-related group (DRG)-reimbursement and length of hospital stay were retrospectively retrieved for each anatomical localization, considering 210 patients.Aims

Endoprosthetic reconstruction with a distal femoral arthroplasty (DFA) can be used to treat distal femoral bone loss from oncological and non-oncological causes. This study reports the short-term implant survivorship, complications, and risk factors for patients who underwent DFA for non-neoplastic indications. We performed a retrospective review of 75 patients from a single institution who underwent DFA for non-neoplastic indications, including aseptic loosening or mechanical failure of a previous prosthesis (n = 25), periprosthetic joint infection (PJI) (n = 23), and native or periprosthetic distal femur fracture or nonunion (n = 27). Patients with less than 24 months’ follow-up were excluded. We collected patient demographic data, complications, and reoperations. Reoperation for implant failure was used to calculate implant survivorship.Aims

Retrospective data over an eight-year period was collected on twenty-four young patients with non-union of a femoral neck fracture who were followed to union. The cause of each nonunion was identified and a classification of the nonunions was established in order clarify treatment options. Patients were treated by a single surgeon. The treatment protocol was based on the classification of the femoral neck nonunion. There were no nonunions in the treated patients; however two patients who showed signs of avascular necrosis prior to treatment ultimately developed AVN. Femoral neck nonunion occurs in 20–30% of displaced femoral neck fractures. If the femoral head is viable, the treatment goal is femoral neck union to maintain it. Treatment options depend on the cause of nonunion. To clarify treatment options, a classification of nonunions was developed. The treatment regime developed was based on the type of nonunion. We believe that subclassification of the
We aimed to evaluate the long-term impact of fracture-related infection (FRI) on patients’ physical health and psychological wellbeing. For this purpose, quality of life after successful surgical treatment of FRIs of long bones was assessed. A total of 37 patients treated between November 2009 and March 2019, with achieved eradication of infection and stable bone consolidation after long bone FRI, were included. Quality of life was evaluated with the EuroQol five-dimension questionnaire (EQ-5D) and German Short-Form 36 (SF-36) outcome instruments as well as with an International Classification of Diseases of the World Health Organization (ICD)-10 based symptom rating (ISR) and compared to normative data.Aims

Introduction: The bone defects in the long bones are traumatic as a consequence of open fractures or resections due to infection or necrotic nonunion. A devitalised bone with no nutrition or vascularity is liable to an infection, with extension proportional to the size of the necrotic bone. To be sure to eliminate the infection and the nonunion it is necessary to perform open surgery and remove the necrotic and infected segments thoroughly, and then proceed to osteosynthesis and internal transport after osteotomy. Material and Methods: From 1981 to 2002 203 cases were treated with the Ilizarov Method. The previous treatment given before the patients came to our center was as follows: 1) in tibial nonunion intramedullary nail 17%; 2) in
Dual plating of distal femoral fractures with medial and lateral implants has been performed to improve construct mechanics and alignment, in cases where isolated lateral plating would be insufficient. This may potentially compromise vascularity, paradoxically impairing healing. This study investigates effects of single versus dual plating on distal femoral vascularity. A total of eight cadaveric lower limb pairs were arbitrarily assigned to either 1) isolated lateral plating, or 2) lateral and medial plating of the distal femur, with four specimens per group. Contralateral limbs served as matched controls. Pre- and post-contrast MRI was performed to quantify signal intensity enhancement in the distal femur. Further evaluation of intraosseous vascularity was done with barium sulphate infusion with CT scan imaging. Specimens were then injected with latex medium and dissection was completed to assess extraosseous vasculature.Aims

In response to the COVID-19 pandemic, there was a rapidly implemented restructuring of UK healthcare services. The The Royal National Orthopaedic Hospital, Stanmore, became a central hub for the provision of trauma services for North Central/East London (NCEL) while providing a musculoskeletal tumour service for the south of England, the Midlands, and Wales and an urgent spinal service for London. This study reviews our paediatric practice over this period in order to share our experience and lessons learned. Our hospital admission pathways are described and the safety of surgical and interventional radiological procedures performed under general anaesthesia (GA) with regards to COVID-19 in a paediatric population are evaluated. All paediatric patients (≤ 16 years) treated in our institution during the six-week peak period of the pandemic were included. Prospective data for all paediatric trauma and urgent elective admissions and retrospective data for all sarcoma admissions were collected. Telephone interviews were conducted with all patients and families to assess COVID-19 related morbidity at 14 days post-discharge.Introduction
Methods
Periprosthetic fracture of the femur is an uncommon complication after total hip replacement, but appears to be increasing. We undertook a nationwide observational study to determine the risk factors for failure after treatment of these fractures, examining patient- and implant-related factors, the classification of the fractures and the outcome. Between 1979 and 2000, 1049 periprosthetic fractures of the femur were reported to the Swedish National Hip Arthroplasty Register. Of these, 245 had a further operation after failure of their initial management. Data were collected from the Register and hospital records. The material was analysed by the use of Poisson regression models. It was found that the risk of failure of treatment was reduced for Vancouver type B2 injuries (p = 0.0053) if revision of the implant was undertaken (p = 0.0033) or revision and open reduction and internal fixation (p = 0.0039) were performed. Fractures classified as Vancouver type B1 had a significantly higher risk of failure (p = 0.0001). The strongest negative factor was the use of a single plate for fixation (p = 0.001). The most common reasons for failure in this group were loosening of the
The aim of this study was to determine if the Oxford Knee and Hip Score (OKHS) can accurately predict when a primary knee or hip referral is deemed nonsurgical We retrospectively reviewed pre-consultation OKHS for all consecutive primary total knee arthroplasty (TKA) and total hip arthroplasty (THA) consultations of a single surgeon over three years. The 1436 knees (1016 patients) and 478 hips (388 patients) included were categorized based on the surgeon’s decision into those offered surgery during the first consultation Aims
Patients and Methods
Double-level lengthening, bone transport, and bifocal compression-distraction are commonly undertaken using Ilizarov or other fixators. We performed double-level fixator-assisted nailing, mainly for the correction of deformity and lengthening in the same segment, using a straight intramedullary nail to reduce the time in a fixator. A total of 23 patients underwent this surgery, involving 27 segments (23 femora and four tibiae), over a period of ten years. The most common indication was polio in ten segments and rickets in eight; 20 nails were inserted retrograde and seven antegrade. A total of 15 lengthenings were performed in 11 femora and four tibiae, and 12 double-level corrections of deformity without lengthening were performed in the femur. The mean follow-up was 4.9 years (1.1 to 11.4). Four patients with polio had tibial lengthening with arthrodesis of the ankle. We compared the length of time in a fixator and the external fixation index (EFI) with a control group of 27 patients (27 segments) who had double-level procedures with external fixation. The groups were matched for the gain in length, age, and level of difficulty score.Aims
