Background.
The aim of this study is to analyse the radiological outcomes and predictors of avascular necrosis following 2-hole DHS in Garden I and II neck of femur fractures in patients more than 60 years with a minimum follow up of one year. We retrospectively reviewed 51 consecutive patients aged more than 60 years who underwent DHS fixation for Garden I and II fractures. Demographics, fracture classification, time to surgery, pre-operative AMTS, preoperative posterior tilt angle, quality of reduction, pre and post-operative haemoglobin(hb), creatinine and comorbidities were analysed for correlation with AVN using Chi-Square test, Independent Sample and paired t test. There were 40 (78.4%) females and the mean age of the cohort was 77 years. 28 and 23 were Garden I and II NOF fractures respectively. Union was observed in all our patients except one(kappa =1). 12/51(23.5%) developed AVN of the femoral head. Statistically significant higher incidence of AVN was noted in patients with a pre-op tilt angle > 200 (p = 0.006). The mean drop in Hb was higher in patients who developed AVN (21.5 g/L) versus the non-AVN group (15.9 g/L) (p = 0.001). There was no difference in AVN rates with respect to laterality, mean time to surgery, pre-op AMTS and Charlson comorbidity index. 4/52 (7.6%) had re-operations (one hardware prominence, two conversions to arthroplasty, one fixation failure during the immediate post-op period). The 30-day and one year mortality rates were 1.9 % and 11.7 % respectively. 2-hole DHS fixation in undisplaced NOF fractures has excellent union rates. A pre-operative posterior tilt angle of >200 and a greater difference in pre and post operative haemoglobin were found to correlate positively with the progression to AVN . No correlation was observed between AVN and time to surgery, laterality, quality of reduction and comorbidities.

Background
Methods
Failure of intertrochanteric fracture fixation often occurs in patients, who have poor bone quality, severe osteoporosis, or unstable fracture patterns. Hip arthroplasty is a good replacement procedure even though it involves technical issues such as implant removal, bone loss, poor bone quality, trochanteric nonunion and difficulty of surgical exposure. The purpose of this study is to evaluate the outcomes of total hip arthroplasty (THA) as the replacement for failed fixation of intertrochanteric fractures of the femur. 203 patients of failed intertrochanteric fractures between April 2009 and October 2014 were included in the study. All of them underwent total hip arthroplasty through direct lateral approach. 150 patients were male (73.8%) and 53 patients (26.1%) were female and the mean of age was 59.02±10.34 years old (range: 56–90 years). The indications of the failure were nail cut out in 174 (85.7%), non-union in 15 (7.3%), plate failure in 14 cases (6.8%). One patient underwent two-stage protocol due to infection. We evaluated the possible clinical and radiological complications and measured functional outcome with modified Harris hip score (MHHS). We used cementless cup in nearly all of patients (95.2%), cementless long stem in 88.1% of patients.Introduction
Patients and Methods
Lag screw cut-out following fixation of unstable intertrochanteric fractures in osteoporotic bone remains an unsolved challenge. A novel new device is the X-Bolt which is an expanding type bolt that may offer superior fixation in osteoporotic bone compared to the standard DHS screw type device. The aim of this study was to test if there was a difference in cut-out using the X-Bolt implant compared with the standard DHS systemIntroduction
Aims
A prospective, randomized, controlled trial was performed to compare the outcome of treatment of unstable fractures of the proximal part of the femur with either a sliding hip screw or a short proximal femoral nail antirotation (PFNA-XS, Synthes). Eighty one patients (April 2007 – May 2008) presenting with unstable fracture of the proximal part of the femur were randomized, at the time of admission, to fixation with use of either a short proximal femoral nail antirotation (n=42) or a sliding hip screw (n= 39). The primary outcome measure was reoperation within the first postoperative year and mortality at the end of one year. Operative time, fluoroscopy time, blood loss, and any intra-operative complication were recorded for each patient. Follow-up was undertaken at 3, 6, and 12 postoperative months and yearly thereafter. Plain AP and lateral radiographs were obtained at all visits. All changes in the position of the implant, complications, or fixation failure were recorded. Hip range of motion, pain about the hip and the thigh, walking ability score and return to work status were used to compare the outcomes. There was no significant difference between 1 year mortality rates for the two groups. Mean Operative time was significantly less in PFNA group (Mean 25 min, range 19 – 56 min) than DHS group (Mean 38 min, range 28 – 70 min). Patients treated with a PFNA experienced a shorter fluoroscopy time and less blood loss. 6 patients in DHS group had implant failure as compared to none in PFNA group. The functional outcome was also better in PFNA group. When compared to DHS, PFNA-XS provides better functional outcome for unstable trochanteric fractures with less operative time, less blood loss and less complications, however one year mortality rate remains the same.
Surgical training has been greatly affected by the challenges of reduced training opportunities, shortened working hours, and financial pressures. There is an increased need for the use of training system in developing psychomotor skills of the surgical trainee for fracture fixation. The training system was developed to simulate
Introduction. Osteoporotic intertrochanteric fracture (ITF) is frequent injuries affecting elderly, osteoporotic patients leading to significant morbidity and mortality. Successful prognosis including union and alignment is challenging even though initial successful reduction with internal fixation. Although many factors are related to the patient's final prognosis. Well reduction with stable fracture fixation is still the goal of treatment to improve the quality of life and decrease morbidity in patients with hip fractures, but this in turn depends on the type of fracture and bone quality. Poor bone quality is responsible for common complications, such as failure of fixation, varus collapse and lag screw cut-out, in elderly patients. Kim et al. found that the complication rate when using conventional DHS in unstable ITFs can be as high as 50% because of screw cut-out. We used the
Background. Despite studies into patient consent and their understanding of the potential risks of trauma surgery, no study has looked at the patient's understanding of the procedure involved with neck of femur fracture surgery. Method. Prospective analysis of 150 patients who had operative fixation of neck of femur fractures in a district general hospital. Patients were asked on the third post-operative day to select which procedure they had undergone from a diagram of four different neck of femur surgeries (cannulated screws, cephalomedullary nail,
Introduction. A recent meta-analysis published in the British Medical Journal suggested an increased risk of infection, but none of the studies were large enough to reach statistical significance. A prospective, randomised trial was designed at our institution to investigate the wound healing and complications related to surgery following fracture neck of femur in the elderly. Objectives. The primary aim was to compare the wound problems and infection following two different methods of skin closure: Subcuticular monocryl suture to metal clips for closure of skin. The secondary aim was to look at the duration of surgery after both types of closure. We received ethical approval for this study. We screened and recruited all eligible patients admitted with acute hip fracture undergoing hemi-arthroplasty or
The aim of this retrospective study was to evaluate the failure rate among different fixation devices for undisplaced fracture neck of femur. All 52 patients with Garden I and II hip fractures who underwent surgery in a teaching hospital in London from January 2007 to June 2012 were included. Electronic patient records were accessed to collect the patient data. There were 52% females and the mean age of patients was 70 years. Thirty patients had cannulated screws, 18 –

Femoral neck stress fractures (FNSF) are uncommon, representing 3.5% to 8% of all stress fractures in military recruits. The majority of displaced FNSF undergo operative fixation and are at risk of avascular necrosis (AVN) and non union with a 40–100% medical discharge rate. We aimed to review the incidence and outcome of displaced FNSF in Royal Marine Recruits. Retrospective review identified 6 Royal Marine recruits, aged 17 to 25, who had suffered a displaced FNSF over a 6 and a half year period. Incidence was 0.93 per 1000 recruits. Patients were treated urgently by operative fixation with a 2 hole
The use of fluoroscopy in orthopaedic surgery creates risk of radiation exposure to surgeons. Appropriate personal protective equipment (PPE) can help mitigate this. The primary aim of this study was to assess if current radiation protection in orthopaedic trauma is safe. The secondary aims were to describe normative data of radiation exposure during common orthopaedic procedures, evaluate ways to improve any deficits in protection, and validate the use of electronic personal dosimeters (EPDs) in assessing radiation dose in orthopaedic surgery. Radiation exposure to surgeons during common orthopaedic trauma operations was prospectively assessed using EPDs and thermoluminescent dosimeters (TLDs). Normative data for each operation type were calculated and compared to recommended guidelines.Aims
Methods
Hemiarthroplasty and proximal femoral fixation are common procedures performed in trauma units, but there is very little information regarding post-operative pain experience. Pain control is a keystone in the successful management of hip fractures. A sound strategy of pain management is easier to implement in patients where pain levels can be predicted, allowing for an effective balanced analgesic regime. Analysis was performed on patients presenting with a hip fracture in two hospitals. Patients with a diagnosis of dementia were excluded. Post-operative pain scores were taken from patient observation charts using a verbal analogue scale. Post-operative opiate consumption was calculated from inpatient drug charts. 357 patients were included, 205 patients underwent a cemented hemiarthroplasty (HG) and 152 had fixation with a
Introduction. Failed operated intertrochanteric fractures (with screw cutout, joint penetration, varus collapse, nonunion, or femoral head avascular necrosis) pose treatment dilemmas. The ideal approach is re-osteosynthesis with autologous bone grafting. When the femoral head is unsalvageable, conversion to a prosthetic hip replacement is necessary. Materials/Methods. Thirty-seven patients with failed
The aim of this study was to establish any association between implant cut-out and a Tip Apex Distance (TAD), ≥25mm, in proximal femoral fractures, following closed reduction and stabilisation, with either a
Failed internal fixation of hip fracture is a problem with varied aetiology. This becomes more complex when associated with infection. Total hip arthroplasty (THA) remains the only option to restore hip biomechanics when there is partial/complete head destruction associated with it. A retrospective review was performed for 22 consecutive patients of THA following failed infected internal fixation between Sept. 2001 and Nov. 2007. There were 11
Introduction. Fracture of the proximal femur frequently occur in children with osteogenesis imperfecta(O.I.) or fibrous dysplasia and may lead to progressive coxa vara and a “shepherds crook” deformity. In adults, these changes introduce difficulties that are not ordinarily encountered with routine osteosynthesis. There is minimal literature on this topic and the cases reported are few in number. Objective. The purpose of this case report was to describe a intertrochanteric fracture in a elderly woman with O.I. successfully treated by 115 degrees hip osteotomy plate and cannulated screws. Methods. We present a case of a 82-year-old female who was injured by falling. She had O.I. type â�£ A according to Sillence. Radiographs showed a intertrochanteric fracture of the femur with severe deformity. The femoral shaft had 25 degrees angular deformity and moderate rotation at the proximal. The angle between femoral neck and shaft was 105 degrees (severe coxa vara) and the proximal femur had a “shepherds crook” deformity (See Figure 1). She had presented 70 years previously ipsilateral fractures of the femur which had healed. These mal-united fracture involved anatomical changes such as medicalization of the femoral canal and intramedullary remodeling and sclerosis (See Figure 2). Recognizing the anatomical changes before and during surgery, standard
Introduction. Intracapsular fractures of the femoral neck in young adults are a surgical emergency. Recent literature reviews have questioned whether the timing of surgery reduces the incidence of avascular necrosis, non-union and revision. A study was performed to determine how many patients met a 12-hour target for operative fixation with this injury. Possible sources of delay to theatre were reviewed. Methods. A Fractures Outcomes Research Database was used to identify patients aged 18–64 who were admitted to the Royal Victoria Hospital in Belfast between 1. st. Jan 2008 and 31. st. Dec 2009. Intracapsular fractures of the femoral neck which were treated with a 2-hole
