Introduction- Proximal humeral fractures remain a challenging problem. Most authors agree that anatomical reduction and stable fixation are essential to allow early range of motion. A variety of techniques have been described such as threaded pins, tension band wiring, screws, nails, plates and primary prosthesis. Locking plates score over other implants by the virtue of providing greater angular stability and better biomechanical properties. The Aim of the Study is to evaluate the functional outcome of PHILOS plate
Introduction.
Background. Stress fractures at tracker after computer navigated total knee replacement are rare. Periprosthetic fracture after Minimally Invasive Plate
We carried out a retrospective review of 47 intra-articular fractures of the calcaneum treated by open reduction and internal fixation in 45 patients by a single surgeon between 1993 and 2001. The fractures were evaluated before operation by plain radiographs and a CT scan using Sanders’ classification.
Introduction.
Lateral tibial plateau fractures are articular fractures that can have a severe prognosis involving a joint biomechanically and functionally very important.
Aim: To compare 2 methods of osteosynthesis (pinning and plate and screws) in displaced intraarticular fractures of the calcaneus. Material and method: Between 2001 and 2005, 82 displaced intraarticular fractures of the calcaneus were surgically treated in our department. Fractures were classified according to Bohler’s classification: 18 Bohler type II and 64 Bohler type III fractures. Open reduction and reconstruction with osseous grafts (autologous grafts in 22 cases and heterologous grafts in 52 cases) were used in 74 cases. In 8 cases (all of Bohler II type) grafts weren’t used.
Purpose of the study:
The most frequent mechanical failure in the osteosynthesis of intertrochanteric fractures is the cut-out. Fracture pattern, reduction quality, tip-apex distance or the position of the cervico-cephalic screw are some of the factors that have been associated with higher cut-out rates. To date, it has not been established whether underlying bacterial colonization or concomitant infection may be the cause of osteosynthesis failure in proximal femur fractures (PFF). The primary objective of this study is to assess the incidence of infection in patients with cut-out after PFF osteosynthesis. Retrospective cohort study on patients with cut-out after PFF osteosynthesis with endomedullary nail, from January 2007 to December 2020. Demographic data of patients (such as sex, age, ASA), fracture characteristics (pattern, laterality, causal mechanism) and initial surgery parameters were collected (time from fall to intervention, duration of surgery, intraoperative complications). Radiographic parameters were also analyzed (tip-apex distance and Chang criteria). In all cut-out cases, 5 microbiological cultures and 1 anatomopathological sample were taken and the osteosynthesis material was sent for sonication. Fracture-related infection (FRI) was diagnosed based on Metsemakers et al (2018) and McNally et al (2020) diagnostic criteria.Aim
Method
Purpose of the study: This study was conducted to assess short- and mid-term radiographic outcome of percutaneous posterior osteosynthesis (Sextant®)of thoracolumbar spine fractures and to identify indications and complications. Material and methods: The Sextant® material was used for 14 patients with a lumbar spine or low thoracic spine fracture. Mean patient age was 40 years (range 19–84). Outcome was reviewed retrospectively.
Purpose of the study: The treatment of thoracolumbar fractures has evolved over the last five years with cementoplasty percutaneous osteosynthesis in addition to the gold standard orthopaedic or surgical treatments. This percutaneous method preserves muscles and maintains reduction to healing. The purpose of this work was to evaluate our results in traumatology patients after five years experience, deducting our current indications. Material and methods: From February 2004 to February 2009, we included 60 patients with a type A or B2 thoracolumbar fracture free of neurological problems and who had more than 10° kyphosis. Reduction was achieved in hyperlordosis before the percutaneous procedure. In other cases we used open arthrodesis. This was a retrospective analysis of a consecutive monocentre series including 37 men and 23 women, mean age 37 years. The injury was L1 and T12 in the majority. Classification was A1 and A3 for the majority.
Introduction:. Percutaneous fixation of intraarticular calcaneal fractures adequately restore the subtalar joint with lower soft tissue complications and equivalent short-term results compared to open fixation. However, studies have largely focused on less severe fracture types (Sanders types 2/3). We report our initial experience of this relatively new Mini-open Arthroscopic-assisted Calcaneal
Intra-articular distal humerus OTA type C fractures are challenging to treat. When osteosynthesis is not feasible one can choose to do a primary arthroplasty of elbow or manage non-operatively. The indications for treatment of this fracture pattern are evolving. We present our outcomes and complications when this cohort of patients was managed with either open reduction internal fixator (ORIF), elbow arthroplasty or non-operatively.Abstract

Introduction: Proximal humeral fractures have been increasing in recent years with the increase in population over 60 years old. 20 to 30% of these fractures require surgical treatment according to the Neer criteria: fragments dislocation greater than 1 cm and/or an angle greater than 45°. A rigid fixation of proximal humeral fractures in elderly patients with osteoporotic bone is not satisfactory; new solutions are sought. The authors describe a minimally invasive technique that uses an intramedullary elastic implant – helix wire. Objective: Evaluate functional outcomes and complication rates in patients with humeral subcapital fractures who underwent fixation with helix wire. Material: Cross-sectional study evaluating patients with subcapital fracture of the humerus who underwent fixation with helix wire. Methods: There were operated 32 patients with proximal humeral fractures with helix wire implant, with an average age of 71 years old (41–90). 9 men and 23 women. According to Neer’s classification: 18 two parts fractures, 12 three parts and 2 four parts.
Fractures of the ankle are common, and they mostly affect young adults. Wound complications are not uncommon following the fixation of these fractures. This study evaluated the impact of HIV on wound healing after plate osteosynthesis in patients with closed ankle fractures. This is an observational retrospective study of patients operated on at a tertiary level hospital. We reviewed hospital records for patients above 18 years of age who presented with wound breakdown following ankle open reduction and internal fixation. The patients’ hospital records were retrieved to identify all the patients treated for closed ankle fractures and those who developed wound breakdown. Patients with Pilon fractures were excluded. The National Health Laboratory System (NHLS) database was accessed to retrieve the CD4 count, viral load, haematology study results, and biochemistry results of these patients at the time of surgery and subsequent follow-up. The x-rays were retrieved from the electronic picture archiving system (PACS) and were assessed for fracture union at a minimum of 3 months follow-up. We reviewed the medical records of 172 patients with closed ankle fractures treated from 2018 to 2022. Thirty-one (18.0%) developed wound breakdown after surgery, and they were all tested for HIV. Most of the patients were male (58.0%), and the average age of the cohort was 43.7 years (range: 21 years to 84 years). Ten of these patients (32.2%) were confirmed HIV positive, with CD4 counts ranging from 155 to 781. Viral load levels were lower than detectable in 40% of these patients. All patients progressed to fracture union at a minimum of 3 months follow-up. We observed no difference between HIV-positive and HIV-negative patients in terms of wound breakdown and bone healing post-plate osteosynthesis for closed ankle fractures.
The purpose of this study is to analyze the demographic and microbiological variables of acute ankle infections posterior to ankle osteosynthesis and to determine the different characteristics of patients with A multicenter retrospective observational study (4 national hospitals) of acute post osteosynthesis infections of ankle fracture operated between 2015 and 2018 was implemented. The demographic and microbiological variables relating to the surgical intervention and the antibiotic treatment performed were collected. A descriptive assessment of all the variables and a univariate comparison between patients with Aim

Additive manufacturing has led to numerous innovations in orthopaedic surgery: surgical guides; surface coatings/textures; and custom implants. Most contemporary implants are made from titanium alloy (Ti-6Al-4V). Despite being widely available industrially and clinically, there is little published information on the performance of this 3D printed material for orthopaedic devices with respect to regulatory approval. The aim of this study was to document the mechanical, chemical and biological properties of selective laser sintering (SLS) manufactured specimens following medical device (TOKA®, 3D Metal Printing LTD, UK) submission and review by the UK Medicines and Healthcare Products Regulatory Agency (MHRA). All specimens were additively manufactured in Ti-6Al-4V ELI (Renishaw plc, UK). Mechanical tests were performed according to ISO6892-1, ISO9585 and ISO12107 for tensile (n=10), bending (n=3) and fatigue (n=16) respectively (University of Bath, UK). Appropriate chemical characterisation and biological tests were selected according to recommendations in ISO10993 and conducted by external laboratories (Wickham Labs, UK; Lucideon, UK; Edwards Analytical, UK) in adherence with Good Lab Practise guidelines. A toxicological review was conducted on the findings (Bibra, UK).Abstract

Management of infection after osteosynthesis (IAO) poses a significant challenge in the setting of multidrug resistant organisms (MDRo). We have analysed whether IAO with MDRo has an adverse outcome. We have retrospectively analysed patients with IAO from January 2001 to November 2016 with a minimum follow up of 12 months after the discontinuation of antibiotics.Aim

Proximal humeral fractures (PHFs) are common. There is increasing evidence that most of these fractures should be treated conservatively. However, recent studies have shown an increase in use of operative treatment. The aim of this study was to identify the trends in the incidence and methods of treatment of PHFs in Finland. The study included all Finnish inhabitants aged ≥ 16 years between 1997 and 2019. All records, including diagnostic codes for PHFs and all surgical procedure codes for these fractures, were identified from two national registers. Data exclusion criteria were implemented in order to identify only acute PHFs, and the operations performed to treat them.Aims
Methods
The influence of rigid fixation and permanent compression on the results, the timing of fusion and rehabilitation after fractures of the femoral neck was investigated. A hip fracture is 60–80% of all fractures of the proximal femur. Despite recent advances in the treatment of this disease, the percentage of unsatisfactory outcomes as high as 25–35%. The choice of surgical treatment in femoral neck fractures in the elderly remains as controversial as it was almost 50 years ago when Speed called him as “the unsolved fracture. Hip replacement is currently the gold standard in the treatment of femoral neck fractures. But compared with the osteosynthesis operation takes more time, is accompanied by massive blood loss, sometimes the need for transfusion and a higher risk of deep wound infection. Given these facts the best is an indoor low-traumatic method of osteosynthesis locking. Compare of the results of femoral neck fractures using of osteosynthesis 3 blade nail, spongious screws and nail for permanent compression. A retrospective analysis of treatment of 252 patients from 1982 to 2015 with subcapitale and transcervical fractures of the femoral neck on the basis “RCTO named by H.J. Makazhanova”. In the research locales patients older than 40 years. All patients were divided according to the applied method of treatment: 1 group of 95 patients operated using a 3-blade-nail, in the 2nd group of 105 patients operated on spongious screws, in the 3 group of 52 patients operated nail for the permanent compression, authoring. All patients underwent x-ray examination before and after surgery. The average period from time of injury before performing the osteosynthesis amounted to 4–7 days. The follow-up period was 6–12 months. The results obtained clinically and radiographically divided into good, satisfactory, poor. Good and satisfactory results were regarded as positive, and poor results as negative. The average age of patients was 67.5 years. Among these female patients − 174 (69%), the male − 78 (31%). Traumatization more prone to elderly accounting for 206 (81.7%) cases, and only 46 (18.3%) in the middle age group. Analysis of the results of treatment showed positive results in 1 group − 69.5 %, in group 2 − 83.8 %, in group 3 − 96.2 %. In the first group of 29 (31.5 %) and in the second group of 17 (16.2 %) patients have postoperative complications: secondary displacement, nail migration, pseudarthrosis, necrosis of head. The patients of third group have postoperative complications in 2 cases (3.8 %): displacement of bone fragments according of retraumatization. Employability was restored in 1 group − 7–9 months, in group 2 - in 6–8 months, 3 group - through 6–6.5 months.
The method of choice for fresh fractures of the femoral neck, especially subcapital fractures in the elderly, is a minimally invasive method of closed compression osteosynthesis. Comparative analysis of treatment results showed that for the consolidation and subcapital transcervical femoral neck fractures can provide rigid fixation of bone fragments. The use of permanent compression is the best method, which shortens the period of consolidation.
Implant-related infection is one of the leading reasons for failure in orthopaedics and trauma, and results in high social and economic costs. Various antibacterial coating technologies have proven to be safe and effective both in preclinical and clinical studies, with post-surgical implant-related infections reduced by 90% in some cases, depending on the type of coating and experimental setup used. Economic assessment may enable the cost-to-benefit profile of any given antibacterial coating to be defined, based on the expected infection rate with and without the coating, the cost of the infection management, and the cost of the coating. After reviewing the latest evidence on the available antibacterial coatings, we quantified the impact caused by delaying their large-scale application. Considering only joint arthroplasties, our calculations indicated that for an antibacterial coating, with a final user’s cost price of €600 and able to reduce post-surgical infection by 80%, each year of delay to its large-scale application would cause an estimated 35 200 new cases of post-surgical infection in Europe, equating to additional hospital costs of approximately €440 million per year. An adequate reimbursement policy for antibacterial coatings may benefit patients, healthcare systems, and related research, as could faster and more affordable regulatory pathways for the technologies still in the pipeline. This could significantly reduce the social and economic burden of implant-related infections in orthopaedics and trauma.
Evaluate if treating an unstable femoral neck fracture with a locking plate and spring-loaded telescoping screw system would improve construct stability compared to gold standard treatment methods. A 31B2 Pauwels’ type III osteotomy with additional posterior wedge was cut into 30 fresh-frozen femur cadavers implanted with either: three cannulated screws in an inverted triangle configuration (CS), a sliding hip screw and anti-rotation screw (SHS), or a locking plate system with spring-loaded telescoping screws (LP). Dynamic cyclic compressive testing representative of walking with increasing weight-bearing was applied until failure was observed. Loss of fracture reduction was recorded using a high-resolution optical motion tracking system.Aims
Methods
In this retrospective study, we re-evaluated the case histories of patients treated for diaphyseal and meta-epiphyseal fractures of the humerus by fasciculated nailing, using the Hackethal method. Our experience, beginning in 1992 through to the present, includes over 400 cases of fractures treated using this method. Among these cases, there were 250 meta-epiphyseal fractures and 200 diaphyseal fractures. Follow-up was possible in 250 cases. The number of complications encountered in the case studies considered was relatively low, including five cases of a delayed union and four cases of non-union. There were no deep or articular infections, five cases of superficial infection, four cases of fracturing of the means of synthesis, 10 cases of procidence of the wires at the level of the insertion site, and two cases of distal migration at the level of the articular cartilage of the humeral head. We did not encounter any cases of periarticular ossification or iatrogenic palsy of the radial nerve. Our methodology foresaw in all cases closed reduction of the fracture as well as epicondylar access distal to the humerus, which in some instances of multi-fragmented fractures was performed bilaterally, with the Eiffel Tower assembling method and four or five retrograde bundle wires. By using the epicondylar point of insertion, the fracture could be reduced and and torsional stability obtained, which together with the bone defect filling contributed to the primary stability of the fracture. In this retrospective study, we wanted to demonstrate the validity of the bundle nailing according to Hackethal’s method, which is distinguished by being a minimally invasive technique as well as by providing good consolidation and a low rate of complications.
This article is based on the analysis of surgical treatment peculiarities of 641 patients with post-osteomyelitis long bones defects. The average age of patients at the time of hospital admission was 32,4 ± 0,7 and ranged from 4 to 70 years. Most of them were people of active working age (476 (74.3%)) and male (523 (81.1%)). In this observation group 566 (88.3%) patients had the osteomyelitis process of the traumatic origin, including post-surgical (n = 155) and post-gunshot injuries (n = 13). Chronic hematogenous osteomyelitis was diagnosed in 75 (11.7%) patients. Most patients had lower extremity bones problems, including 444 tibia defects and 142 femoral bone defects. Much fewer patients had the osteomyelitis process of the upper extremity (humerus, radius, ulnar bone – 18, 19 and 18 respectively). Purulent necrotic process was accompanied by nonunion bone fragments in 160 (24%) patients, delayed union in 95 (14.6%) patients, false joint in 178 (27.6%) patients, segmental bone defect in 75 (11 5%) patients and bones union with edge defects and cavities in 143 (22.3%) patients. 340 (53%) patients were operated using the method of free bone grafting, and 301 (47%) patients were operated using the distraction method. The need to use the bilocal for external fixation on upper extremities occurs quite seldom (twice in our observations). Even when there is an upper extremity bone defect of several centimeters the preference should be given not to bilocal external fixation. When treating the lower extremities taking the above mentioned into consideration, segmental defects predominated, that is why the bilocal distraction-compression method of surgical treatment prevailed (98.6%). Thus, the main method of upper extremities long bones defects replacement is free bone grafting with segment fixation by the external fixation device, for lower extremities the is not-free main Ilizarov method, which allows to get positive results in 84.6% of patients with femoral bone problems and in 96.4% of tibia problems, mainly due to one-step treatment, directed simultaneously to inflammatory process elimination and maximum possible anatomical and functional restoration of the affected extremity.
Pilon fractures and distal metaphyseal fractures of the tibia are associated with a high rate of soft tissue and bone healing problems. We started to use the XS and XS nail as minimal invasive procedure for the management of these fractures in July 2000 first for the fibula and since for the fibula and pilon itself but extended metaphseal comminution are contraindication for the XS nail. Because of soft tissue problems and higher loading capacity of intramedullary implants the XS Nail was also used for ankle fracture osteosynthesis but as in all articular fractures with open reduction, the XS nail is a 4.5mm or the XXS a 3.5mm straight nail witch is locked by threaded wires witch are placed with an aiming device and allows also dynamic fracture site compression with a set screw. The Fibula is fixed percutaneusly and after distal locking with traction of the aiming device also tibia length and axis can be restored and fixed with the proximal locking. From july 2000 to july2006 54 pilon fractures where treated. The mean age was 54 years (range 25–92). In all cases except one referred after 4 weeks the fibula and joint dislocations where stabilised primarily. The tibia XS nail osteosynthesis or limited invasive plate fixation was performed after 5–8 days except two fixed primarily. Up to now 43 patients could be re-examined more than 12 months after surgery. The results were classified according to the Ovadia Score. In a second study: from 05/2000 to 03/2002 214 ankle fractures were stabilised with a XS or XXS nail. The mean age was 51 year, 59% were woman. 35% were Weber B and 25% type C fractures. The re-examination after 6 months could be performed in 91 Patients and was evaluated according to the Ovadia score (clinical and radiological).Clinical Problem
Material and Methods
The so called “floating knee” is the result of ipsilateral fractures of femur and tibia. The definition of floating knee dates back to 1974, when Blake and Mc Bryde proposed it in order to move the attention from the skeletal plane of the lower limb to the articular and vasculonervous plane of the knee, where complications are more frequent and dreadful: lesions of popliteal artery or sciatic nerve, stiffness or instability of the knee. The timing of surgical treatment is still debated: in fact it may be immediate but provisional, with necessity of a second operation, or delayed but definitive. Also the strategy of osteosynthesis may be controversial, because of the association of fractures. We present a series of 3 cases (among them there were also 2 ipsilateral fractures of patella) with both femur and tibia treated by osteosynthesis with plate (1 case, with complications) or nail (2 cases, without complications): the patients were followed-up clinically and with X-rays for 1 year. Our experience confirms the gold standard for this kind of fractures is locked intramedullary nailing, retrograde for femur and antegrade for tibia.
Despite the increase of surgical procedures for extremities injuries and improvement of various fixation devices and surgical methods, the number of unsatisfactory osteosynthesis results reaches 2–7%. Chronic osteomyelitis after lower extremities long bones osteosynthesis occurs in 1.3–23% of cases, and the percentage of bone nonunion due to infections reaches 83%. We conducted a retrospective analysis of 237 patient treatment with chronic osteomyelitis following tibial and femoral bone osteosynthesis. Two groups were selected for the analysis: the first group contained 194 patients treated with sheets and the second one contained 43 patients treated with intramedullary locked nails. In cases of unconsolidated fractures and false joints, the necrectomy was performed with single-step or two-step replacement of internal fixation for external fixation. In this case segmental bone defects reached 20.9% in the first group and 3.6% in the second one. Here the treatment was performed using the Ilizarov method with the bone defect distraction replacement. Conclusions. 1. Chronic osteomyelitis following sheets usage, unlike the osteomyelitis following the intramedullary locked osteosynthesis, leads more often to the formation of edge and segmental bone defects, which significantly prolongs the treatment duration. 2. External fixation application for postoperative osteomyelitis treatment in case of the bone nonunion made it possible to eliminate the purulent process and restore the extremity support function. 3. The inflammatory process relapses reached 14.9% in the first group and 3.1% in the second one.
This work refers to a male patient, 25 years of age, admitted in the Emergency Department following a bicycle accident, of which resulted an open fracture of the right forearm bones – Gustillo & Anderson I. With this work, the authors have as objective the description of the patient's clinical condition – starting with the fracture, over to the osteomyelitis – as well as the surgical procedures and remaining treatments he was submitted to. The authors used the patient's records from Hospital's archives, namely records from the Emergency Department, Operating Room, Infirmary and Consultation, and also the diagnostic exams performed throughout the patient's clinical evolution. This clinical case began in May 2013, when the patient suffered an open fracture of the right forearm bones – Gustillo & Anderson I – due to a bicycle accident. At the time, the exposure site was thoroughly rinsed, a cast immobilization was made, and antibiotics were prescribed. In the fifth day following the trauma, the patient was submitted to an open reduction with internal fixation with plate and screws of both forearm bones. In the following period, the distal segment of the suture suffered necrosis, exposing the radial plate and the tendons of the first dorsal compartment. The Plastic Surgery team was then contacted, proposing the execution of a graft over the exposed area, which was made in August 2013. In the postoperative period, about half the graft lost its viability and it was noted that a radial pseudoarthrosis had developed – in the context of osteomyelitis – with a defect of about 9 centimeters. This condition prompted the extraction of the osteosynthesis material, about 4 months after its application, and at the same time the first stage of a Masquelet Technique was performed. The second stage of the aforementioned procedure was carried out two months later. Currently, the patient is clinically stable, with right hand mobility acceptable for his daily living activities. Analyzing the patient's clinical evolution, we concluded that, even though the adequate therapeutic decisions have been made in each stage, the development of osteomyelitis was inevitable. This realization, in association with the patient's young age, raises debatable questions of therapeutic order.
1. The healing of the radius and tibia in dogs after compression plating of osteotomies made by a Gigli saw was studied. 2. The methods used were indian ink microangiography and terramycin labelling. The Spalteholz technique and azane colouring were used. 3. Revascularisaton of the fracture region took place both from newly formed vessels in the Haversian systems and from periosteal and endosteal vessels. 4. The fracture gap was filled at an early stage by a vascular network. Under stable conditions direct angiogenic bone formation took place around this network. 5. Rebuilding of the cortical bone in the fracture region occurred by osteoclastic activity. Groups of osteoclasts made cavities in the necrotic bone and were immediately followed by loops of vessels; behind and around the loop new bone was formed. Another form of bone absorption consisted of bundles of vessels which eroded necrotic cortical bone without new bone formation. 6. The new bone was initially oriented along the fracture gap but, by conversion into secondary osteones, it became progressively oriented longitudinally in the direction of the original bone. 7. Under stable conditions some periosteal and endosteal callus formation occurred though it was of slight importance. It regressed very soon and was seldom seen in the radiographs.
Aim of this study is to present the first clinical trial on an antibiotic-loaded fast-resorbable hydrogel coating In this prospective, multi-centre, randomized, controlled, prospective study, a total of 260 patients were randomly assigned, in five European orthopaedic centres, to receive the antibiotic-loaded DAC coating or to a control group, without coating. Pre- and post-operative assessment of laboratory tests, wound healing, clinical scores and x-rays were performed at fixed time intervals.Aim

determining the possible presence of anatomical variations of the safe-zone and analyzing the anatomical congruence of precontoured plates to this zone.
(flat) (25 %), (slightly concave) (63,6 %) and (markedly concave) (11,4 %), Adherence of a precoundered plate (Acumed) to the bone surface of the safe zone was performed independently by three of us, and the gap between plate and bone was measured. Plate adaptability was good in Type B, scarce in Type C and absent in Type A.
The olecranon is exposed to high tension and bending forces. In 2/3 multifragment fractures occur. Tension belt and plate fixation in these not only transverse but also sagital and frontal plane fractures is often not possible. As a central weight bearing device the XS 4,5mm nail is exposed to a lower bending moment and a angle stable transverse fixation with 2,4mm threaded wires every 9mm is possible. Also a soft tissue independent fracture compression with a set screw (proximal longitudinal holes) is possible. Additional frontal and sagital plane fragments can be fixed to the system with fibre wire hemicerclages. From 5.1999 to 12.2002 80 consecutive cases with XS nail osteosynthesis of a olecranon fracture were treated and 73 (91%) could be re-examined clinically and radiological 15 months after surgery. 13,7% were open fractures 67% were 3 or more part fractures. For evaluation the Murphy score was used. The mean time for surgery was 37min for two part and 56 min. for more part fractures. The Murphy score showed in 64% very good and in 29% good results. Only in 4 patients with more part fractures with additional radius head fractures and previous surgery had fair or unsatisfactory results. The XS nail is a new concept for stabilisation of all but specially of complex and very comminuted olecranon fractures with a very low complication rate and good functional results.
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. 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.Introduction
Objective
Intraarticular fractures of the distal humerus comprise 1% of all fractures in adults. Triceps reflecting and olecranon osteotomy approach provide adequate exposure in intraarticular fracture with its own advantage and disadvantages. Forty consecutive patients with fractures of the distal humerus were treated over a 36-month period. The patients were randomly allotted into two groups; group A consists of twenty patients with olecranon osteotomy and group B consists of twenty patients with triceps reflecting approach. In both the groups fracture was fixed using orthogonal or parallel plating techniques. Clinical outcome was assessed using the DASH SCORE, radiological union and complications was noted in both the group and compared. In group A the mean DASH score was 15.9 points. Three patients underwent a second procedure for hardware removal, 2 patients had non-union at osteotomy site, one patient had transient ulna nerve neuropraxia and one patient had superficial infection. In group B the mean DASH score was 14 points. There was no statistical significance between both groups regarding final outcome except complications were more in osteotomy approach. We conclude both approach is an effective procedure with an excellent or good functional outcome but osteotomy approach has more complications.
Until recently, diaphyseal fractures in children aged 4–12 years were treated conservatively. Although Prof. Havránek recommended oblique bilateral skin traction in his monograph entitled Split Russell Traction, he is currently inclined to use skeletal traction through the proximal tibia (Goteborg traction). The author himself stresses that this therapy requires great expertise from the medical staff. In addition, patients are immobilised for several weeks in hospital. The Pediatric Traumatology School in Nancy, France prepared a method of intramedullar elastic ostheosynthesis according to Métaizeau and Prévote. After our experience with intramedullary fixation using Prévote’s nails in diaphyseal fractures of adults and diaphyseal forearm fractures, we also decided to use this ostheosynthesis in diaphyseal femoral fractures of children. Our group includes four patients (2 boys, 2 girls) with a mean age of 4.2 years (range 4–11). Average time from injury to operation was eight hours. The patient is in a supine position and given a general anaesthesia. After repositioning, two or more Prévot nails are inserted above the distal physis from the medial and lateral side towards the femoral diaphysis. The nails cross distally and proximally to the fracture line and are anchored in the intertrochanteric area. The operative procedure usually lasts approximately thirty minutes. The patient is hospitalised from two to five days. The child walks with crutches after discharge, and trains the operated lower extremity. According to the parents, these children began to load the extremity spontaneously after two weeks. After four weeks we perform a radiographic check and permit full loading. The bars are removed in eight weeks in children up to the age of seven years, and 12 weeks in older children. All of the children recovered without any problems. The schedule for follow-up is from nine to twelve months. The extremities do not appear to have a tendency to overgrow. The method of mini-invasive osteosynthesis of diaphyseal femoral fractures in children aged from four to twelve years is a modern alternative to conservative treatment. It is more comfortable for the patients, avoids the skin complications of traction therapy, and significantly shortens the time of treatment. This method will also be particularly useful in treating polytraumatised patients.
Unstable intertrochanteric fractures may be treated by several types of implants, most frequently by dynamic sliding hip screw or some form of intramedullary implant. Intramedullary implants began to be used in cases with an expectation of further improvement of osteosynthesis stability. A need to determine the advantages of single implants for selected types of fractures in randomized trials was defined. In addition to biomechanical principles, bone quality is considered, together with increasing possibilities in recent years of further improving density measurements, especially qCT with respect to local specificity. A series of 86 patients (24 men, 62 women, average age 77,6 years) was operated on from September 6, 2005 to June 30, 2009 for unstable intertrochanteric fracture (31 A2.1, A2.2, A2.3), either by DHS of PFN osteosynthesis after randomization. A CT examination of both hip joints in a predefined manner was performed before surgery. Using special software the relative density of the central spherical part of the femoral head 2 and 3 centimetres in diameter was determined. After fracture healing, the dynamization of the neck screw of both implants and the reduction of vertical distance between the tip of the neck screw and subchondral bone of the femoral head were determined. In addition to evaluation of osteosynthesis stability and osteosyntheis failure, clinical parameters such as surgical time, blood loss and length of hospital stay were compared between the two groups of patients. Survival of patients was evaluated with respect to April 21, 2010. In the patient series, 4 failures of DHS osteosynthesis (cut out) and 2 failures of PFN osteosynthesis (cut out) were noted. Sliding of the DHS was on average 11,9 mm, and was significantly higher in comparison to dynamization of the PFN neck screw, which was 6,9 mm (p=0,005). When comparing the vertical distance between the tip of the neck screw and subchondral bone of the femoral head immediately after surgery and after fracture healing the average reduction of the vertical distance was 1,6 mm in DHS osteosynthesis and 0,8 mm in PFN osteosynthesis. The difference was statistically significant (p=0,025). PFN seems to provide a more stable fixation, based on the measurements. The number of failed DHS osteosyntheses is higher in comparison to the number of failed PFN osteosyntheses but the difference is not statistically significant. The influence of femoral head density on osteosynthesis failure could not be determined due to a low number of failed osteosyntheses in both patient groups. At the same time, after statistical analysis, influence of the relative femoral head density on vertical distance reduction between the screw tip and femoral head subchondral bone in healed fractures was not proven. Statistically, average length of surgical time, length of hospital stay, mean blood loss and survival did not differ significantly between the two patient groups.
The aim of the study was to evaluate the results of subtrochanteric femoral fractures treatment with a 90 degrees condylar blade plate, using indirect reposition technique.
Surgical treatment aims at restoring anatomical elements to a condition stable enough, to allow early mobilization to avoid secondary displacement. The blood supply of the humeral head should not be damaged, so the risk of avascular necrosis will be minimal. This work offers a new surgical technique that dramatically reduces the need for dissection of soft tissues while using a new locked plate.
The two arms of this Y shaped plate embrace the humeral head. The anterior arm overbridges the biceps longus tendon and fixes the lesser tuberosity, with a locked screw in the head. The posterior arm fixes the greater tuberosity with an another locked screw. These two screws cross each other at nearly right angle thus giving optimal fixation in the head.
The main complications were 3 algodystrophies, 1 hematoma, 4 failures of fixation, 2 nonunions and only one necrosis.
We present a consecutive series of 19 patients with 22 intra-articular calcaneal fractures treated by percutaneous arthroscopic fixation (percutaneous arthroscopic calcaneal osteosynthesis “PACO”). Traditional open reduction and fixation regularly has significant wound complications. PACO has the advantage of direct visualization of the joint surface reduction with the benefit of minimal soft tissue trauma and wound complications. Between July 2010 & April 2012, 39 isolated closed intra-articular calcaneal fractures were admitted to St Mary's Hospital. All Sanders type 2 and type 3 fractures were included. Undisplaced fractures (13) were treated non-operatively and comminuted type 4 fractures (4) were treated with primary arthroscopic fusion. Surgery was performed on the next list with no delay for swelling. All patients had pre and post op CT scans. Patients were discharged in a temporary cast with routine follow up at 2, 6 and 12 weeks.Introduction
