We have reviewed retrospectively 80 patients who were treated for traumatic fractures of the femur with a Grosse-Kempf nail to assess the incidence and causes of persisting pain in the proximal
Delayed onset muscle soreness (DOMS) in the quadriceps is frequent in runners finishing a marathon race, and may result in several days of discomfort and pain. There is an increasing clinical evidence that noninvasive, pulsed electromagnetic field therapy (PEMF) can have physiological effect on inflammation and tissue repair. The purpose of this pilot study was to investigate the effect of PEMF on quadriceps muscle soreness in marathon runners and to use the data to calculate an appropriate sample size for a subsequent study. The design was a randomized double-blind prospective study covering a 5 days period after completion of a beach marathon. After the marathon all 74 runners that completed the 42.195 km were asked to participate in the study. Forty-six agreed to enter the study and were block randomized into an intervention group or a control group. The intervention group received an active pulsed electromagnetic field device, and the control group received a sham device. The sham devices were used in exactly the same manner but produced no electromagnetic field. The active PEMF device does not produce heat or cause any sensation in the tissue allowing participants to be blinded to treatment. The pulsed electromagnetic field signals of a 2-msec burst of 27.12-MHz sinusoidal waves were repeated at two bursts per second. Peak magnetic field was 0.05 G, which induced an average electric field of 10 mV/cm in the tissue with an effect of 7.3 mW/cm3. All subjects were instructed to place the device on the most painful area of the quadriceps for 20 minutes four times a day. Pain intensity was measured three times a day with the Visual Analogue Scale (VAS) during a 90o squat with a self-administered questionnaire. Data were non-parametric and compared with a two-sample Wilcoxon rank-sum test.Introduction

The Thompson hemiarthroplasty is a common treatment option for acute neck of femur fractures in the elderly population. Our department noted a significant number of patients returning with
Introduction. Distraction histogenesis is utilised for cosmetic reasons in patients with constitutional short stature, achondroplasias, or height dysphoria. One of the considerations of patients and surgeons alike, is the preservation of aesthetically acceptable body proportions after the lengthening i.e which segment of the lower limb to lengthen and by how much, in order to preserve the patient's proportions within -or as close as possible to- the normal range of human body proportions. Sound anthropometric data on the normal range of the human body proportions is currently lacking. The aim of this study is to calculate the normal range of the ratio between the lengths of the lower limb, upper limb, femur, tibia, stature and trunk. Methods. Data form standardized measurements of the lengths of the tibia, femur, arm, stature, lower limb, upper limb was obtained from a sample population of 6068 healthy men and women servicing in the US Army. The mean, median, range and standard deviation were calculated for the following ratios of lengths: whole lower limb/leg, Stature/leg, Whole lower limb/
Haemorrhage is the main cause of preventable death on the modern battlefield. As IEDs in Afghanistan become increasingly powerful, more proximal limb injuries occur. Significant concerns now exist about the ability of the CAT tourniquet to control distal haemorrhage following mid
Background. For some time, optimized perioperative pathway protocols have been implemented in orthopedic surgery. In our hospital an accelerated clinical pathway has been successfully in effect for several years, focused on safely decreasing patients' length of stay and increasing their function at the time of discharge. The aim of the present project was to evaluate whether a further optimization is even more promising regarding early postoperative outcome parameters. Materials and Methods. Prospective, parallel group design in an Orthopaedic University Medical Centre. 143 patients, scheduled for unilateral primary total knee replacement (TKR) under perioperative regional analgesia were included. 76 patients received a Standard Accelerated Clinical Pathway (SACP). 67 patients received an Optimized Accelerated Clinical Pathway (OACP) including patient-controlled regional analgesia pumps, ultra-early/doubled physiotherapy and motor driven continuous passive motion machine units. Main measures were early postoperative pain on a visual analogue scale, consumption of regional anaesthetics, knee range of motion, time out of bed, walking distance/stair climbing, circumference measurements and Knee Society Scores of the operated leg. Patients in both groups were checked for a possible discharge by a blinded orthopedic surgeon on the 5th and 8th postoperative (po) day, using a discharge checklist including the KATZ Index of Independence in Activities of Daily Living, standard requirements for pain at rest/mobilization, walking distance and regular wound healing. A potential discharge was only approved if the patient was able to meet all six criteria from the discharge checklist. Re-admission within 6 weeks after discharge from hospital was registered. Results. Patients within the OACP had significant benefits regarding stair climbing/walking distance/time-out-of bed/circumference measurements of the
Introduction. Fracture healing is governed by biological and mechanical factors. Circular frames are one method to fix fractures. Recently, the number of frame designs that are available has increased and these different designs may have different effects on the mechanical environment created. The senior author has been concerned by the stability of the construction when a short frame is used. This study examined the stability of different frames and the possible use of additional 7th struts to aid stability. Method. The frame configuration was modified with increasing strut angles from 15° − 70°. Each frame was cyclically tested in compression to 200N. The Taylor Spatial Frame was retested with the addition of a seventh strut. Results. Frame stability significantly deteriorated with shorter struts. This was particularly apparent at angles less than 30°. Stiffness was significantly improved with the addition of a seventh strut. Conclusions. Ring-strut angle, plays a significant factor in hexapod frame stability. Stability can be improved with the addition of a seventh strut. This may be particularly important in the paediatric community and in frame around the
Objective. To investigate the outcomes of patients following the chipping procedures as an alternative to bone grafting in treatment of femoral non-unions. Design. Retrospective evaluation of prospectively collected data. Setting. University hospital. Level IV, therapeutic case series. Patients. Eleven patients with femoral non-union were included. The median age of patients was 37 years (range, 19–73 years). The median follow-up was 24 months (range, 12–60 months). Intervention. Non-unions were treated by the chipping procedure and re-install of an intramedullary nail or locked plate(s). Main Outcome Measurements. Radiographic bone union, walking ability, and complication were evaluated. Results. All non-unions clinically and radiographically healed with a median time of 7.5 months (range, 6–12 months). All patients were able to walk without walking aids within 9 months after surgery. Pre-existing deformities (e.g., varus and mal-external rotation) were anatomically corrected after the revision surgery for non-union. There were no superficial or deep infections, but post-operative temporal anemia and swelling of the
In a recent publication, 4.6% of 6450 Coalition deaths over ten years were reported to be due to junctional bleeding. The authors suggested that some of these deaths could have been avoided with a junctional hemorrhage control device. Prospectively collected data on all injuries sustained in Afghanistan by UK military personnel over a 2 year period were reviewed. All fatalities with significant pelvic injuries were identified and analysed, and the cause of death established. Significant upper
Objective. To investigate the outcomes of patients following the chipping procedures as an alternative to bone grafting in treatment of non-unions after long bone fracture. Patients. Sixteen patients with femoral or tibial non-union were included. The median follow-up was 24 months. Intervention. Non-unions were treated by the chipping procedure and re-install of an intramedullary nail or locked plate(s) without bone grafting. Main Outcome Measurements. Radiographic bone union, walking ability, and complication were evaluated. Results. Fourteen non-unions clinically and radiographically healed with a median time of 7.5 months. For these cases, patients were able to walk without walking aids within 9 months after surgery. Pre-existing deformities (e.g., varus and mal-external rotation) were anatomically corrected after the revision surgery for non-union. Radiographic consolidation could not been obtained for two cases within 12 months after chipping procedures; one nonunion after old osteomyelitis and another after supracondylar fracture. Lack of stability at chipping site may be one of the reasons for failure of the procedures. Post-operative temporal anemia and swelling of the
The treatment for trochanteric femoral fractures is still challenging. Since 2005, we are using 2 new implants: Gamma3™ nail and the PFN-A™. All patients with a fracture of the trochanteric area were included in an observational study during 3 years. Objectives were radiographics and clinics (complications) comparaison of these 2 new devices. We included 426 patients (236 Gamma3™ nails, 190 PFN-A™). We faced the epidemiological data, per and post-operative complications. The tip-apex distance and the position of the cephalic implant were studied. The 2 implants were well positionned in more than 80%, with no statistic diffferencie. We found a a cut-out rate of 1,4 % and a re-operation rate of 4,9 %. These rates of usual complications are very low in comparaison with litterature. We did not found a statistic difference between these 2 differents nails. But, we observed 2 unusual complications: for the Gamma3™ nail, a high rate of automatic distal locking failure, and for the PFN-A™, many patients complained of
Pin-site infection remains a significant problem for patients treated by external fixation. A randomized trial was undertaken to compare the weekly use of alcoholic chlorhexidine (CHX) for pin-site care with an emollient skin preparation in patients with a tibial fracture treated with a circular frame. Patients were randomized to use either 0.5% CHX or Dermol (DML) 500 emollient pin-site care. A skin biopsy was taken from the tibia during surgery to measure the dermal and epidermal thickness and capillary, macrophage, and T-cell counts per high-powered field. The pH and hydration of the skin were measured preoperatively, at follow-up, and if pin-site infection occurred. Pin-site infection was defined using a validated clinical system.Aims
Methods
Revision hip surgery is reportedly rising inexorably yet not all units report this phenomenon. The outcome of 1143 consecutive Corin TaperFit primary hip arthroplasties (957 patients) performed between 1995 and 2010 is presented. The implants were cemented under pressurisation and combined the TaperFit stem with Ogee flanged cups. Data was gathered from local arthroplasty database and case note review of revised joints. 13 hips have been revised (1.1%). Cumulative prosthesis survival is 0.99 +/− 0.0. Two femoral stems were revised (0.2%); one at 6 months for sepsis, one at 14 days after dislodgment during reduction of dislocation. No revisions were undertaken for aseptic loosening of the stem or cup, nor for
Introduction. We present a series of patients who have had secondary reconstruction of war injuries to the upper and lower limbs, sustained during the Iraq and Afghanistan conflicts. Material and Methods. All patients were seen at the combined Peripheral Nerve Injuries Clinic at the Defence Medical Centre for Rehabilitation, Headley Court. All surgery was performed at Odstock Hospital. Procedures include scar excision and neurolysis (all patients), release of scar contractures, tenolysis, tendon transfers, revision nerve grafts, excision of neuroma, and soft tissue reconstruction using pedicled or free flaps. Results. 24 patients have been treated at the time of submission. We have using 13 free flaps (1 free groin flap, 9 anterolateral
Aims. Will Hydroxyapatite hip (HA) arthroplasty associated with ceramic bearings produce uncomplicated function in younger, active patients’ The incidence of aseptic loosening, dislocation and broken implants has been particularly investigated. Debris disease from plastic debris contributes to aseptic loosening. Hard-Hard bearings should obviate this problem. Metal-metal will release ions which might be deleterious. Experience with metal-metal resurfacing has high lighted problems including pseudo-tumours. Ceramic bearings may fracture but otherwise appear free of complications. Methods. This is a study extending over 19 years of 626 HA hip arthroplasties with ceramic bearings. Annual review using Harris Hip Score to assess pain and function and X-rays to check osseointegration has been performed. Alumina ceramic was inserted in 467 hips. The newer Zirconia Toughened Alumina (ZTA) has been inserted in 169 hips. There are 118 hips still under review at 10 or more years. Results. Aseptic loosening is unusual (one stem, two acetabulae (3 of 1252 components, 0.24%) Failure from mal-orientation with repeated dislocation occurred in six hips (0.96%). Three alumina heads (0.48%) and two alumina liners (0.32%) broke. There has been no failure of ZTA ceramic. No patients have

Currently, periprosthetic fractures are excluded from the American Society for Bone and Mineral Research (ASBMR) definition of atypical femoral fracture (AFFs). This study aims to report on a series of periprosthetic femoral fractures (PFFs) that otherwise meet the criteria for AFFs. Secondary aims were to identify predictors of periprosthetic atypical femoral fractures (PAFFs) and quantify the complications of treatment. This was a retrospective case control study of consecutive patients with periprosthetic femoral fractures between 2007 and 2017. Two observers identified 16 PAFF cases (mean age 73.9 years (44 to 88), 14 female patients) and 17 typical periprosthetic fractures in patients on bisphosphonate therapy as controls (mean age 80.7 years (60 to 86, 13 female patients). Univariate and multivariate analysis was performed to identify predictors of PAFF. Management and complications were recorded.Aims

Patients and Methods
Bisphosphonates are widely used as first-line treatment for primary and secondary prevention of fragility fractures. Whilst they have proved effective in this role, there is growing concern over their long-term use, with much evidence linking bisphosphonate-related suppression of bone remodelling to an increased risk of atypical subtrochanteric fractures of the femur (AFFs). The objective of this article is to review this evidence, while presenting the current available strategies for the management of AFFs. We present an evaluation of current literature relating to the pathogenesis and treatment of AFFs in the context of bisphosphonate use.Objectives
