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 thigh. At a mean of 21 months after operation 33 patients had residual pain severe enough to interfere with their lifestyle or mobility. This was in the region of the scar on the greater trochanter in three-quarters of the patients. Only four showed no radiological abnormality. There was nonunion of the fracture in two, Paget’s disease in one, breakage of the nail in two and prominence of the proximal locking screw in five, although we found no correlation between prominence of the nail and pain. There was a strong relationship between pain and heterotopic ossification at the proximal end of the implant; this was present in 64% of the patients with pain as compared with those without pain (p < 0.001, Mann-Whitney U test). Of the 80 patients, 27 had the implant removed after 18 months, 17 of them because of pain. In six of these 17, the pain was not relieved. Prominence of the nail proximally was not associated with pain, but protuberance of laterally-based proximal locking screws caused problems. We found a strong association between heterotopic bone formation and pain, but it is uncertain whether this is the true cause or merely an indication of some other factor such as traumatic damage to the glutei during insertion of the nail. Removal of the implant does not always cure such pain

Introduction

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 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 thigh pain, radiographic loosening and femoral osteolysis following cemented implantation of the titanium alloy version of the Thompson hemiarthroplasty. We are not aware of any previous reports documenting complications specific to the titanium Thompson implant and a retrospective cohort study was therefore initiated following clinical governance approval. 366 titanium alloy Thompson prostheses were implanted for hip fracture treatment between 2017 and 2020. As of February 2023, 6 of these have been revised at our hospital. 5 were revised for symptomatic femoral osteolysis and 1 presented with an acute periprosthetic fracture. All revised cases were determined to be aseptic. 32 living patients were excluded from recall on compassionate grounds due to permanent nursing home residence. 47 living patients were identified of which 33 attended for xray. 28 deceased and/or nursing home resident patients who had pelvis x-rays in the previous 12 months were also included in the analysis. Including the 6 index hips already revised, a total of 61 hip xrays were analysed, of which 19 hips (31.1%) showed radiographic evidence of femoral osteolysis or loosening. We conclude that there is a concerning incidence of femoral osteolysis and implant loosening associated with the titanium Thompson implant. We have discontinued use of the implant and reported our experience to the MHRA. We encourage other Scottish Health-Boards who use this implant to consider enhanced follow-up

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/thigh, Stature/thigh, Siting height/whole lower limb, Stature/Whole lower limb, Arm Span/Stature, Whole upper limb/Whole lower limb. Results. The ratios show normal distribution. Results are presented separately for men and women for the total sample population and for subgroups based on ethnic origin (White, Black, Hispanic and Asian). Discussion. This study is one of the first to provide specific anthropometric data from a large sample population relevant to the evidence-based preoperative planning and patient counselling before cosmetic limb lengthening procedures

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 thigh application. Aim. To evaluate the efficacy of the CAT windlass tourniquet in comparison to the newer EMT pneumatic tourniquet. Method. Serving soldiers were recruited from a military orthopaedic outpatient clinic. Participants' demographics and blood pressure were recorded and a short medical history obtained to exclude any arteriopathic conditions. Doppler ultrasound was used to identify the popliteal pulses bilaterally. The CAT was randomly self-applied by the participant at mid thigh level and the presence or absence of the popliteal pulse on Doppler was recorded. The process was repeated on the contralateral leg with the CAT now applied by a trained researcher. Finally the EMT tourniquet was self applied to the first leg and popliteal pulse change Doppler recorded again. Results. 40 consecutive patients were invited to participate in the study. 15 declined to participate. 1 was excluded via pre-determined exclusion criteria. A total of 24 participants were recruited. The self applied CAT occluded popliteal flow in only 4 subjects (16.6%). The CAT applied by a researcher occluded popliteal flow in 2 subjects (8.3%). The EMT prevented all popliteal flow in 18 subjects (75%). Discussion. This study demonstrates that the CAT tourniquet is ineffective in controlling arterial blood flow when applied at mid thigh level. The EMT was successful in a significantly larger number of participants

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 thigh/Knee Society function score on the 5th po day and stair climbing/circumference measurements of the thigh on the 8th po day, and reduction of the consumption of regional anaesthetics. No significant reduction in length of stay was observed. Discussion. Early postoperative functional process indicators tended to be higher within the OACP group, but the main effects flatten in the course of the first eight postoperative days. Further, prospective randomised clinical trials with uniform, objective discharge criteria are needed

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 thigh were a larger ring may increase the strut angle

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 thigh were common complications after surgery. Conclusions. Chipping the non-union site was likely to enhance fracture healing, and this technique was useful as an alternative to bone grafting in treatment of femoral non-union, especially for both atrophic and hypertrophic non-unions with deformities

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 thigh, groin or pelvic injuries were recorded in 124 casualties, of which 92 died. Pelvic injury was the cause of death in 42; only 1 casualty was identified where death was at least in part due to a vascular injury below the inguinal ligament, not controlled by a tourniquet, representing <1% of all deaths. Twenty one deaths were due to vascular injury between the aortic bifurcation and the inguinal ligament, of which 4 survived to a medical facility. Some potentially survivable deaths due to exsanguination may be amenable to more proximal vascular control. We cannot substantiate previous conclusions that this can be achieved through use of a groin junctional tourniquet. There may be a role for more proximal vascular control of pelvic bleeding

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 thigh were common complications after surgery. Conclusions. Chipping the non-union site was likely to enhance fracture healing, and this technique was useful as an alternative to bone grafting in treatment of femoral non-union, especially for both atrophic and hypertrophic non-unions with deformities

Aims

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.

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 thigh pain resulting from a prominent cephalic blade. These 2 new complications can be avoided by small changes in the operative procedure. In our mind these 2 implants can be used for treating all patients with trochanteric fracture, but we need other studies to compare these nails with the new generation of sliding plate

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 thigh pain. 32 patients (32 hips) ≥15 year follow up, 13 survive today and none have been revised (0%). Of the 471 with ≥10 year follow up, 38 were aged ≤50 at time of surgery and 1/38 has been revised to date (PLAD for dislocation). The strong population stability in this region, supported by independent investigation by Scottish Arthroplasty Project, endorses the accuracy of the data quoted. The low incidence of revision in this cohort, and absence of revision for aseptic loosening (mean follow up 8.03 years +/− SD 3.94; range 18 months to 16yrs 2 months), substantially supports the longevity and use of cemented, double-taper, polished, collarless femoral stems in combination with cemented polyethylene cups in primary hip arthroplasty in all patient age groups

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 thigh, 3 parascapular, with 4 as through-flow flaps) and 1 pedicled groin flap, with no flap losses. There were 6 amputation stump revisions (1 above elbow, 5 below knee). The majority (n=23) have had nerve recovery distal to the level of injury following revision surgery. Conclusions. Nerve repairs recover following neurolysis (and revision nerve graft if necessary) with provision of good soft tissue cover. Release of scar contractures with flap cover allows healing of chronic wounds and permits mobilisation of joints. Thin fasciocutaneous flaps provide good contour and can be elevated more easily than skin grafted muscle flaps for secondary surgery. Free or regional flaps are preferable to local flaps in high energy-transfer military wounds. Immediate complex reconstruction is not always appropriate in multiply-injured patients

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 thigh pain. Osteolysis and debris disease have not arisen. Harris Hip Scores show 91.2% scoring over 90 or 100. Lower scores mostly relate to other joint and medical problems. Conclusions. Assessments confirm that patients remain well. Aseptic loosening of HA hips is rare at 0.24%. Failure from broken alumina components is unusual. Alumina has now been superseded by ZTA for implantation. Ceramic on ceramic is a reliable selection for bearing surfaces in patients of any age and either sex

Objective. To assess the beneficial use of polypropylene mesh impregnated with vancomycin in an experimental model open fractures Gustilo IIIa in rabbits. Material and Method. We worked with 15 New Zeland White rabbits. All of them were carried out under general anaesthetic, a 5-cm incision longitudinal was made at the back of the right thigh. The femur was aproached and a fracture was performed with a shear, giving rise to a multifragment fracture. The wound remained open for 6 hours with the bone exposed, in a non-surgical ambient. Subsequently underwent surgical cleaning of the open fractures in two stages. The fracture was stabilized with an intramedular pin. The animals were sorted in 3 different therapeutic groups:. Group 1: (5 rabbits) without other treatment. Group 2: (5 rabbits) a polypropylene mesh was placed around the fracture. Group 3: (5 rabbits) a polypropylene mesh with vancomycin was placed around the fracture. The wound was closed with nylon stiches. Three weeks postoperative, the animals were intervened surgically under general anesthesia, after aseptic cure and placement of surgical fields, femoral bone biopsies, soft tissue and mesh were taken. The rabbits were sacrified. The samples were sent to pathology and bacteriology labs. Results. The bacteria isolated were as follows: Escherichia coli, Pasteurella multocida, Staphylococcus spp., Clostridium spp. Mamheinia spp. The Clostridium spp. is a common contaminant in the exposed fractures present in the environment. The Pasteurella mustocida is a microorganism present in the oral cavity of rabbits, as well as Escherichia coli is a germ present in the animal's digestive tract. Mannheimia spp. It is a beta-hemolytic organism, found in the nasal flora of these animals and their pathological role is not elucidated. Staphylococcus spp. is a germ that is found in the normal flora of the animals skin. Group 1 showed a relative risk for an infection. For Group 2 the relative risk was substantially greater than 1.4, while in Group 3, the relative risk was 0.6, significantly lower than the previous two groups. The results have shown a beneficial effect of the use of impregnated polypropylene mesh with vancomycin in this animal group. Conclusion. The use of polypropylene meshes with vancomycin could be useful in the treatment of muscle and ligamentary deficits in patients with open fractures Gustillo IIIa

A total of 63 women who had an operation for a fracture of the hip was randomly allocated to one year of treatment either with anabolic steroids, vitamin D and calcium (anabolic group) or with calcium only (control group). The thigh muscle volume was measured by quantitative CT. The bone mineral density of the hip, femur and tibia was assessed by quantitative CT and dual-energy x-ray absorptiometry and of the heel by quantitative ultrasound. Quantitative CT showed that the anabolic group did not lose muscle volume during the first 12 months whereas the control group did (p< 0.01). There was less bone loss in the proximal tibia in the anabolic group than in the control group. The speed of gait and the Harris hip score were significantly better in the anabolic group after six and 12 months. Anabolic steroids, even in this moderate dose, given in combination with vitamin D and calcium had a beneficial effect on muscle volume, bone mineral density and clinical function in this group of elderly women

Aims

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.

Aims

The aim of this study was to evaluate near-infrared spectroscopy (NIRS) as a continuous, non-invasive monitor for acute compartment syndrome (ACS).

Objectives

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.
