The Birmingham Hip Resurfacing (BHR) arthroplasty has been used as a surgical treatment of coxarthrosis since 1997. We present 20-year results of 234 consecutive BHRs performed in our unit. Between 1999 and 2001, there were 217 patients: 142 males (65.4%), mean age 52 years (18 to 68) who had 234 implants (17 bilateral). They had patient-reported outcome measures collected, imaging (radiograph and ultrasound), and serum metal ion assessment. Survivorship analysis was performed using Kaplan-Meier estimates. Revision for any cause was considered as an endpoint for the analysis.Aims
Methods
Adverse spinal motion or balance (spine mobility) and adverse pelvic mobility, in combination, are often referred to as adverse spinopelvic mobility (SPM). A stiff lumbar spine, large posterior standing pelvic tilt, and severe sagittal spinal deformity have been identified as risk factors for increased hip instability. Adverse SPM can create functional malposition of the acetabular components and hence is an instability risk. Adverse pelvic mobility is often, but not always, associated with abnormal spinal motion parameters. Dislocation rates for dual-mobility articulations (DMAs) have been reported to be between 0% and 1.1%. The aim of this study was to determine the early survivorship from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) of patients with adverse SPM who received a DMA. A multicentre study was performed using data from 227 patients undergoing primary total hip arthroplasty (THA), enrolled consecutively. All the patients who had one or more adverse spine or pelvic mobility parameter had a DMA inserted at the time of their surgery. The mean age was 76 years (22 to 93) and 63% were female (n = 145). At a mean of 14 months (5 to 31) postoperatively, the AOANJRR was analyzed for follow-up information. Reasons for revision and types of revision were identified.Aims
Methods
Adverse spinopelvic mobility (SPM) has been shown to increase risk of dislocation of primary total hip arthroplasty (THA). In patients undergoing THA, prevalence of adverse SPM has been shown to be as high as 41%. Stiff lumbar spine, large posterior standing pelvic tilt and severe sagittal spinal deformity have been identified as risk factors for increased hip instability. Dislocation rates for dual mobility articulations have been reported to be 0% to 1.1%. The aim of this study was to determine the early survivorship from the Australian National Joint Replacement Registry (AOANJRR) of patients with adverse SPM who received a dual mobility articulation. A multicentre study was performed using data from 229 patients undergoing primary THA, enrolled consecutively. All the patients who had one or more adverse spine or pelvic mobility parameters had a dual mobility articulation inserted at the time of their surgery. Average age was 76 (22 to 93) years and 63% were female. At a mean of 2.1 (1 – 3.3) years post-op, the AOANJRR was analysed for follow-up. Reasons for revision and types of revision were identified. The AOANJRR reported two revisions. One due to infection and the second due to femoral component loosening. No revisions for dislocation were reported. One patient died with the prosthesis in situ. Kaplan Meier survival was 99.3% (CI 98.3% − 100%) at 2 years. DM bearings reduce the risk of dislocation of primary THA in patients with adverse spine and pelvic mobility.
The aim of this study was to assess the incidence, management and survival of unstable pelvic ring injuries in patient aged 65 years or older. Prospectively kept data was analysed from April 2008 to October 2016. Information regarding the mechanism, fracture type, associated injuries, treatment and complications of the treatment were collected. Annual incidence was calculated and a Kaplan Meier survival analysis for carried out at 30 days, 1 year and 5 years. 404 patient records were available. 125 were 65 years or older (60 males and 65 females). 24 (19%) patients required surgical stabilisation to permit mobilisation the remaining 101 patients, treated conservatively were mobilised with immediate weight-bearing under the supervision of a physical therapist with assistive devices. Mean age was 73.5 years (SD 9.9 yrs). Fracture types were − 61.B2 47(37.6%), 61.B1 24(32%), 61.A2 17(13.6%), 61.C1 16(12.8%), 61.C2 5(4%), 61.A1 2(1.6%) and 61.C3 3(2.4%). Mechanisms of injury included fall from standing height − 41 (32%), road traffic collisions − 46(36.8%), fall from higher than standing height − 10(8%), fall from horse − 6(4.8%), jumped from bridge − 3(2.4%) & others 19(15%). Complications in surgical group included 1 death from PE and 1 wound infection treated with vacuum assisted dressing. Survivorship was 91.7%(30 days), 82.5%(1 year) and 49.7%(5 years). Most common fracture type is 61.B2. Over one third of fractures resulted from low energy mechanism. The majority 81% could be managed conservatively. One-year survival figure closely resembles the fracture neck of femur group, highlighting the frailty of this population.
The aim of this study was to statistically analyse the incidence and distribution of humerus fractures in the adult age group between 3rd and 10th decades. The total number of patients was retrieved from the audit department of the hospital using the codes to identify patients between 1997 and 2009. The data included total number of patients aged 20 to 100 years who were either reviewed in the fracture clinics or admitted to the hospital with forearm fractures along with patient gender, age at the time of incident and time of the year the incident occurred. Annual incidence of fractures along with the distribution of fracture incidence per year and per individual month was calculated. The patients’ age were classified in to 3rd to 10th decades. Linear regression analysis was carried out to identify the relationship between fracture incidence and the age or time of the injury. Correlation coefficients(R) and r2 were calculated for all the regression analyses. SPSS (version 16) and Microsoft Excel 2007 were used for statistics.Aims
Methods
The aim of this study was to statistically analyse the incidence and distribution of forearm fractures in the adult age group (3rd–10th Decades) between 1997 and 2009. Records of patients with forearm fractures were retrieved from the hospital audit department using the predetermined codes to identify patients. The data included total number of patients between 20 and 100 years who were either reviewed in the fracture clinics or admitted to the hospital with forearm fractures along with patient gender, age at the time of incident and time of the year the incident occurred. Incidence of total fractures per year and per each month in the year was calculated. The patients were divided into age groups between 2nd to 10th decades. Linear regression analysis was carried out to identify the relationship between fracture incidence and the age or time of the injury. Correlation coefficients(R) and r2 were calculated for all the regression analyses. Fractures were also classified according to the Orthopaedic Trauma Association (OTA) classification system. SPSS (version 16) and Microsoft Excel 2007 were used for statistics.Aims
Methods
The aim of this study was to assess the radiographic outcome by using Lindstrom grading for the management of Malone 2A and 2B fractures by 3 different methods of treatment. The three different methods included manipulation under anaesthesia, k-wire fixation and open reduction internal fixation. Between March 2006 and February 2007, 62 intra-articular distal radius fractures were retrospectively selected. 31 patients including 21 females and 9 males with an average age of 62 years were classified as Malone 2A fractures and 32 patients including 18 females and 14 males with an average age of 64.5 years were classified as Malone 2B fractures. 18 patients had manipulation under anaesthetic (MUA) and immobilisation in a plaster of paris (POP) cast, 27 patients had manipulation and k-wire fixation and 17 patients had open reduction internal fixation (ORIF) of the fractures. All the patients had radiographic assessment at 6 weeks post op using Lindstrom grading. Grade 1 and 2 were considered acceptable, grade 3 and 4 were considered unacceptable.Aims and objectives

The aim of this study was to statistically analyse the calcaneal fractures occurring in the community and distribution within the various age groups divided into decades. Records of calcaneal fractures were retrieved from the audit department of the hospital using the various codes to identify patients reviewed in the clinics or admitted to the hospital between 1997 and 2009. The data collected included the total number of calcaneal fractures, total number in either gender, age at the time of incident, month of the year the incident occurred. Annual distribution of incidence of forearm fractures was calculated for every year and every month of the year. The age of the patients was divided into decades. Linear regression analysis and correlation coefficients were calculated between the incidence of fractures and different variables including age, gender and the time of the injury.Aims and objectives
