Background. One of the prime concerns when managing patients in plaster casts is loss of reduction. There have been studies showing that proper moulding of the plaster cast is critical in maintaining reduction. Recent studies have negated concerns that fibreglass (FG) casts do not allow swelling, when compared to plaster of Paris (POP) casts. However, their potential in maintenance of reduction has not been investigated. Materials and methods. We compared the three-point bending properties of FG casts with POP casts over the first 48 hours. The effect of splitting the casts, at one hour and 24 hours, was studied. Three identical jigs with hinged metal rods were designed to simulate a Colles fracture. The bending force was provided by 0.5 kg weight applied at one end of the jig. The resultant displacement was measured to nearest 0.01 mm over the next 48 hours. Each test was repeated 6 times (total 6 groups and 36 tests). Results. Most deformation occurred within 1 hour for FG casts and 24 hours for POP casts. The total deformation in FG cast (mean 2.4 mm) was significantly less than in POP casts (mean 4.7 mm) (p < 0.01). Splitting at 1 hour increased the final deformation of the POP cast and not of the FG cast (p < 0.05). No significant difference was noticed if the casts were split at 24 hours. Conclusion. Three-point moulding with FG casts can provide better constant loading at the fracture site than the POP casts. Early setting of FG cast allows earlier splitting. We recommend clinical trials to ascertain the safety and efficacy of split FG casts

Introduction. To investigate if the gap index measured in the follow-up X-rays predicts the reduction of swelling in the plaster cast thereby increasing the risk of re-displacement of fracture treated by manipulation alone. Materials/Methods. We selected for this study a cohort of children who presented with a traumatic displaced fracture of distal radius at the junction of metaphysis and diaphysis who were treated with manipulation alone. This cohort was chosen because of the high risk of re-displacement following closed manipulation of this unstable fracture and to maintain uniformity of the fracture type. Cast index and Gap index was measured in the intra-operative radiograph and at two-weeks to note the change in these indices. Gap index which is measured by summing radial and ulnar translation/inner diameter of cast in the AP X-ray and similar translation on the lateral x-ray/inner diameter of cast, with a measure of <0.15 considered to be a satisfactory cast. Results. Forty-one children with a mean age of 9 years (mode-8, range 4–15 yrs) admitted between Jan 2008 and Feb 2010 with the above described fracture and were treated with manipulation alone were included in this study. Serial radiographs show a gradual loss of reduction in 34 (83%) children and 17 (41%) of these children required re-manipulation. As the plaster cast was not changed the cast index remained same while the gap index increased in the follow-up x-rays as the swelling subsided. In those children whose reduction remained satisfactory, the initial gap index was 0.14 which changed to 0.18 (n=7, p>0.05) while in children in whom the fracture lost reduction, the initial gap index was 0.18 and changed to 0.25 (n=34, p=0.0092) at two weeks. Conclusion. Gap index can easily be calculated on follow-up radiographs and can be used to assess the adequacy of plaster cast. From this study we can conclude that it is effective in assessing the adequacy of plaster cast as the swelling subsides

Introduction and aims. Cast immobilisation of paediatric forearm fractures has traditionally used plaster of Paris. Recently, synthetic casting materials have been used. There have been no studies comparing the efficacy of these two materials. The aim of this study is to investigate whether one material is superior for paediatric forearm fracture management. Methods. A single-centre prospective randomised trial of patients presenting to the Women's and Children's Hospital with acute fractures of the radius and/or ulna was undertaken. Patients were enrolled into the study on presentation to the Emergency Department and randomised by sealed envelope into either a fiberglass or plaster of Paris group. Patients then proceeded to a standardised method of closed reduction and cast immobilisation. Clinical follow-up occurred at one and six weeks post-immobilisation. A patient satisfaction questionnaire was completed following cast removal at six weeks. All clinical complications were recorded and cast indexes were calculated. Results. Initially 50 patients were recruited to the study, with equal randomisation. There were no significant differences between the patient demographics of the two groups. The results from this sample indicated an increase in clinical complications involving the plaster of Paris casting group. These complications included soft areas of plaster requiring revision, loss of reduction with some requiring re-manipulation and a high rate of cast spliting due to material swelling. The fractures that loss reduction had increased cast indices. Fibreglass casts were also preferred by patient and their families, with many observational comments regarding the light-weight and durable nature of the material. Conclusions. Cast immobilisation of paediatric forearm fractures is a common orthopaedic treatment. There is currently no evidence regarding the best material for casting. This study suggests that both clinical outcomes and patient satisfaction are superior with fiberglass casts, we are continuing this study to enable greater power with our results

Purpose. To elucidate whether there is an advantage in external fixation supplementation of K-wires in comparison to K-wires and plaster, in the treatment of distal radius fractures without metaphyseal comminution. Indications. Distal intraarticular radius fractures, Frykman VIII or VIII without metaphyseal comminution. Contraindications. Metaphyseal comminution, general medical contraindications for surgical intervention. Study design. Fifty-one patients were prospectively randomised in two groups: 24 patients were treated with K-wire and spanning external fixation supplementation, and 27 were treated with K-wires and plaster. Results. Patients were monitored following the operation with a minimum follow up of 1 year, and checked independently of surgeon for pain, satisfaction and range of motion. There was a statistically significant difference in favour of the external fixation patient group for pain (Visual Analogue Score, Ex-Fix group: mean 14.9, plaster group: mean 28.1, p<0.001) and satisfaction (Ex-Fix group: mean 89.7, plaster group: mean 76.3, p<0.001,). Although one would expect that range of motion would be reduced in the external fixation group, there were no statistically significant differences found in favour of plaster; on the contrary supination results were surprisingly in favour of the external fixation group (Ex-Fix group: mean 54.4, plaster group: mean 45.2, p<0.05). Conclusion. In this study, external fixation supplementation of K-wiring had statistically significant superior results in patient satisfaction score, pain score, and wrist supination in comparison to plaster augmentation of K-wiring

Most of current literatures advise on thromboprophylaxis with injectable LMWH for trauma patients. Injectable anticoagulants have got inherent problems of pain, bruising and difficulty in administering the drug, which leads to low compliance. Clexane is derived from a pig's intestinal mucosa, hence could be objectionable to certain proportion of patients because of their religious beliefs. Oral anticoagulants have been used as thromboprophylactic agents in hip and knee arthroplasty. However there is not enough literature supporting their use as thromboprophylactic agent in ambulatory trauma patients with ankle fracture being managed non-operatively as out-patient. This study looks into the efficacy of oral anticoagulant in preventing VTE in ambulatory trauma patients requiring temporary lower limb immobilisation for management of ankle fracture. The end point of this study was symptomatic deep vein thrombosis (either proximal or distal) and pulmonary embolism. Routine assessment with a VTE assessment risk proforma for all patients with temporary lower limb immobilisation following lower limb injury requiring plaster cast is done in the fracture clinic at this university hospital. These patients are categorised as low or high risk for a venous thromboembolic event depending on their risk factor and accordingly started on prophylactic dose of oral anticoagulant (Rivaroxaban - Factor Xa inhibitor). Before the therapy is started these patients have a routing blood check, which includes a full blood count and urea and electrolyte. Therapy is continued for the duration of immobilisation. Bleeding risk assessment is done using a proforma based on NICE guideline CG92. If there is any concern specialist haematologist advice is sought. A total of 200 consecutive patients who presented to the fracture clinic with ankle fracture, which was managed in plaster cast non-operatively, were included in this study. They were followed up for three months following injury. This was done by checking these patients’ radiology report including ultrasound and CT pulmonary scan (CTPA) test on hospital's electronic system. Fracture of the lateral malleolus which include Weber-A, Weber-B and Weber-C fractures were included in the study. Also included were bimalleolar fractures and isolated medial malleolus fractures. Complex pilon fractures, polytrauma and paediatric patients were excluded from the study. Only one case of plaster associated isolated distal deep vein (soleal vein) thrombosis was reported in this patient subgroup. There was no incidence of proximal deep vein thrombosis or pulmonary embolism. No significant bleeding event was reported. Injectable low molecular weight heparin (LMWH) rather than oral anticoagulant has been recommended by most of the studies and guidelines as main thromboprophylactic agent for lower limb trauma patients

Aim. To demonstrate the effect of location of the split of the plaster on the raised intercompartmental pressure in the volar and dorsal compartments. Methods. Artificial forearm skeleton was used along with two half litre saline bags on ether side representing volar and dorsal forearm compartment. A single layer of cotton wool with half width overlap was applied followed by three rolls of 10cm x 2.5 m plaster of paris. This was then left to dry for four hours. Both the saline bags had an eighteen gauge catheter inserted that was connected to the central venous pressure monitoring line on the anaesthetic machine. Baseline pressure in mmHg was recorded. Normal saline was then injected in both the bags so as to raise the pressure to 50 mmHg in each compartment. POP cast was then split, spread and then the wool was cut down to the saline bags while continually monitoring the pressures. The respective change in the pressure at the end of each step was recorded. Six simulated forearm models had dorsal splits and an equal number had volar splits. The effect of the site and various steps of splitting on the drop in respective compartment pressures was compared. Results. The mean drop in pressure was 24mmHg after all the steps of splitting were completed. This was independent of the site of the split of the cast. The mean drop in ICP after spreading the cast was statistically significant (P=0.01) when compared to cutting cast and cutting wool. Conclusions. Split in cast has similar effect on both, same side and opposite side, compartments in reducing the ICP. Spreading of the cast is the most effective step in reducing the raised ICP and should not be missed

Introduction

Ankle fractures are one of the commonest orthopaedic injuries. A substantial proportion of these are treated non-operatively at outpatient clinics with cast immobilization. Recent literature and NICE guidelines suggest risk assessment and provision of appropriate thromboembolism in patients with lower limb casts. We conducted this survey to assess the current practice in UK regarding thromboembolism prophylaxis in these patients.

The closed management of fractures and the application of plasters remains a core component of orthopaedic trauma management. A prospective audit was undertaken to analyse the quality of plasters presenting from various sources to the Fracture Clinic Plaster Technicians. A prospective audit was conducted of 120 consecutive cases that presented to the Plaster Technicians at Western Health which had plasters applied by other institutions or other departments. The plasters were assessed on a number of criteria for adequacy and appropriateness using a standardised questionnaire and set guidelines. 63% of plasters applied were found to be deficient, inadequate or needed improvement. Of those applied by Theatre doctors, only 20% were appropriate. Of plasters applied by Emergency doctors only 10% were appropriate and those applied by General Practitioners were consistently deficient. Only trained plaster technicians had an acceptable rate of >90%. A large portion of the errors were due to incorrect moulding, joint position and fracture alignment. Improperly applied plasters lead to increased morbidity, require reapplication or unnecessary operative procedures due to loss of position. Ongoing education and review is critical to address this situation, and a national online database is being designed and implemented to monitor this situation nationally

Introduction. The management of patients with open leg fracture in Ivory Coast does not meet the standards of developed countries due to socio-economic conditions, accessibility and organization of care. However, is this care problematic? Is it associated with more post-traumatic infection or mechanical complications and are these correlated with the delay for treatment and the method of treatment?. Material and Methods. This is a single-center prospective study conducted on between January 2018 and May 2018 at Bouaké University Hospital. The observed parameters included factors related to patient, fracture and treatment conditions and were correlated with the rates of complications by multivariate analysis. Results. Fractures, mostly comminuted (69.8%), occurred following a road accident (93%). The series has 30 Gustilo 1 and 2 fractures and 13 Gustilo 3 fractures. The average delay before surgery was 26.6 ± 8.1 hours. Fracture stabilization required the use of a cast, an external fixator or an unlocked nail in 27, 10 and 6 cases, respectively. Complications developed in 28 patients (65%), including 17 malunions and 22 postoperative infections. 11 infections were controlled but 8 developed chronic osteomyelitis and 3 septic non-unions. Uncomplicated union was observed in only 15 cases and an acceptable functional outcome in only 16 cases. Gustilo Grade 3 fractures were associated with an increased risk of complication (p=0.02). The delay of management was not correlated with the appearance of a complication. In contrast, the use of plaster immobilization was significantly associated with an increased risk of complications and infection (p = 0.001). Conclusion. The management of open fractures in our conditions is associated with a high rate of complications and a satisfactory result in a small number of patients. More than the delay of management, the immobilization modalities by plaster and the insufficiency of this method of contention are correlated to the complications. The development of a National Health Care system covering the expenses for emergent treatment, including rapid transportation to hospitals and availability of external fixators at a lower cost would most probably contribute to a reduction of complications and infection. Keywords. Open fractures, developing countries, fixation, operative time

Treatment of acute Achilles tendon rupture is based on obtaining and maintaining apposition of the ruptured tendon ends. Surgical treatment utilises direct suture repair to produce this objective, while conservative or non-surgical management achieves the same effect of closing the tendon gap by immobilisation of the ankle joint in a plantar flexed position within a plaster cast or POP. There is still variability in the conservative treatment practices and protocols of acute Achilles tendon ruptures. The purpose of this study is to examine the current practice trends in the treatment of Achilles tendon ruptures amongst orthopaedic surgeons in the UK. A postal questionnaire was sent to 221 orthopaedic consultants in 25 NHS hospitals in the Greater London area in June 2010. Type and duration of immobilisation were considered along with the specifics of the regime used. Ninety questionnaires were returned giving a 41% response rate. Conservative treatment methods were used by 72% of respondents. A below knee plaster was the top choice of immobilisation (83%) within this group. The mean period of immobilisation was 9.2 weeks (Range 4-36). Weight bearing was allowed at a mean of 5.3 weeks (range 0-12). The specific regime used by consultants was quite heterogeneous across the group, however the most used immobilisation regimen was a below knee plaster in equinus with 3 weekly serial plaster changes to a neutral position, for a total of nine weeks. A heel raise after plaster removal was favoured by 73% of respondents used for a mean period of 6.4 weeks (Range 2-36). In response to ultrasound use as a diagnostic tool, 42.4% of respondents would never use it, 7.6% would use it routinely, while 50% would use it only according to the clinical situation. Comparison of foot and ankle specialists with non-specialists did not reveal a significant difference in practice in duration of immobilisation or time to bearing weight. Conservative management remains a widely practice option in the treatment of Achilles tendon ruptures. Although there are available a number of modern walking aids, the concept of functional brace immobilisation is not as widely used as below knee plaster cast immobilisation, which remains a popular choice amongst orthopaedic surgeons today. There is still no consensus on the ideal immobilisation regimen although a below knee plaster in equinus with serial changes for a total of nine weeks is the most frequently used choice. Further randomised controlled trials are required to establish the optimal treatment strategy for conservative management of Achilles tendon rupture

Background. Scaphoid fractures with displacement have a higher incidence of nonunion and unite in a humpback position that can cause pain and reduced movement, strength and function. The aim of this study is to review the evidence available and establish the risk of nonunion associated with management of displaced scaphoid fractures in a plaster cast. Methods. Electronic databases were searched using the MeSH (Medical Subject Headings) controlled vocabulary (scaphoid fractures, AND'd with explode displaced, or explode nonunion, or explode non-healing or explode cast immobilisation, or explode plaster, or explode surgery). As no randomised or controlled studies were identified, the search was limited to observational studies based on consecutive cases with displaced scaphoid fractures treated in a plaster cast. The criterion for displacement was limited to gap or step of more than 1mm. The ‘random effects’ calculation was used to allow for the possibility that the results from the separate studies differ more than would be expected by chance. Results. Of the 27 articles identified, seven studies were eligible for the meta-analysis with a total of 1401 scaphoids. 93% (1311 scaphoids) of these scaphoid fractures healed in a plaster cast. 207 (15%) of all scaphoid fractures showed displacement of at least 1mm (Gap/step) between fracture fragments. Nonunion was identified in 18% (37/207) of displaced scaphoid fractures treated in a plaster cast. The pooled odds ratio of fracture nonunion between the displaced and undisplaced groups was five times higher with fracture displacement (pooled odds ratio: 5.5, 95%CI: 2.5–12.3; p=0.00, I. 2. =54.6%). The pooled relative risk of fracture nonunion was 4.4 (95%CI: 2.3–8.7; p=0.00 I. 2. =54.3%). Conclusions. Displaced fractures of scaphoid have a four times higher risk of nonunion when treated in a plaster cast and the patients should be advised of this potential risk

Background and Aims:. Forearm fractures are common in the paediatric population and most are treated in a moulded plaster of Paris (POP) cast. It is our concern that many casts applied by our registrars are sub-optimal and that we need to improve our training process. The aim of our study was to review the adequacy of forearm cast application in paediatric patients at our institution and to identify if there is a need for a more formal training program with regard to plaster cast application. Methods:. A retrospective review of control x-rays of forearm fractures treated at our institution was undertaken. X-rays that were reviewed were done as part of the routine treatment protocol. X-ray measurements to assess POP application were the cast index and the gap index. A cast index of > 0.81 and Gap index of > 0.15 were regarded as an indication of poor cast application. Results:. Adequate control X-rays of twenty eight patients with a forearm fracture were available. The average patient age range was 5–12 years. There were thirteen distal metaphyseal fractures, nine diaphyseal fractures and six Salter-Harris type fractures. Of the 28 patients, 20 patients had a poor cast index and 17 patients had poor gap index. In 12 patients both the gap and the cast index were unacceptable. Conclusion:. Our study suggests that paediatric forearm plaster cast application by registrars at our institution is inadequate. This indicates a need for a strategy to improve the training in plaster cast application amongst our registrars

Acute metatarsal fractures are a common extremity injury. While surgery may be recommended to reduce the risk of nonunion or symptomatic malunion, most fractures are treated with nonoperative management. However, there is significant variability between practitioners with no consensus among clinicians on the most effective nonoperative protocol, despite how common the form of treatment. This systematic review identified published conservative treatment modalities for acute metatarsal fractures and compares their non-union rate, chronic pain, and length of recovery, with the objective of identifying a best-practices algorithm. Searches of CINAHL, EMBASE, MEDLINE, and CENTRAL identified clinical studies, level IV or greater in LOE, addressing non-operative management strategies for metatarsal fractures. Two reviewers independently screened the titles, abstracts, and full texts, extracting data from eligible studies. Reported outcome measures and complications were descriptively analyzed. Studies were excluded if a rehabilitation program outlining length of immobilization, weight-bearing and/or strengthening approaches was not reported. A total of 12 studies (8 RCTs and 4 PCs), from the 2411 studies that were eligible for title screening, satisfied inclusion criteria. They comprised a total of 610 patients with acute metatarsal fractures, with a mean age of 40.2 years (range, 15 – 82). There were 6 studies that investigated avulsion fractures, 2 studies on true Jones fractures, and 4 studies with mixed fracture types. Studies assessed a variety of treatment modalities including: WB and NWB casts, elasticated support bandages, hard-sole shoes, plaster slippers, metatarsal shoe casts, and air cast boots. Most studies investigated the outcomes of NWB casts and elasticated support bandages. The NWB short leg cast had no reported non-unions, delayed-unions, or refractures for avulsion fractures. In true Jones fractures, there was an average non-union rate of 23.6% (range, 5.6 – 27.8%), delayed-union rate of 11.8% (range, 5.6 – 18.8%), and refracture rate of 3% (range, 0 – 5.6%). Overall, the average AOFAS score was 87.2 (range, 84 – 91.7) and the average VAS score was 83.7 (range, 75 – 93). The elasticated support bandage had an average non-union rate of 3.4% (range, 0 – 12%), and delayed-union rate of 3.8% for acute avulsion fractures, with no reported refractures. No included study arm investigated outcomes of elasticated support bandages for the true Jones fracture. The average AOFAS score for elasticated support bandages was 93.5 (range, 90 – 100). The average VAS score was 88.9 (range, 90 – 100). Most acute metatarsal fractures heal well, with good-to-excellent functional outcomes and moderate-to-high patient satisfaction. Conservative strategies for avulsion fractures are highly successful and based on this data the authors recommend patients undergo a schedule that involves 3 – 4 weeks in an elasticated support bandage, short leg cast, or equivalent, and WB thereafter as tolerated, with return-to-activity after clinical union. Despite poorer conservative outcomes for true Jones fractures, patients should undergo 8 weeks in a NWB short leg cast, followed by a walking cast or hard-sole shoe for an additional 4 – 6 weeks, or until clinical union. However, surgical consultation is recommended

Stable ankle fractures can be successfully treated non-operatively with a below knee plaster cast. In some European centres it is standard practice to administer thromboprophylaxis, in the form of low molecular weight heparin, to these patients in order to reduce the risk of deep venous thrombosis (DVT). The aim of our study was to assess the incidence of DVT in such patients in the absence of any thromboprophylaxis. We designed a prospective study, which was approved by the local ethics committee. We included 100 consecutive patients with ankle fractures treated in a below knee plaster cast. At the time of plaster removal (6 weeks), patients were examined for signs of DVT. A colour doppler duplex ultrasound scan was then performed by one of the two experienced musculoskeletal ultrasound technicians. We found that 5 patients developed a DVT. Two of these were above knee, involving the superficial femoral vein and popliteal vein respectively. The other three were below knee. None of the patients had any clinical symptoms or signs of DVT. None of the patients developed pulmonary embolism. Of these five patients, four had some predisposing factors for DVT. The annual incidence of DVT in the normal population is about 0.1%. This can increase to about 4.5% by the age of 75. DVT following hip and knee replacement can occur in 40-80% of cases. Routine thromboprophylaxis may be justified in these patients. However, with a low incidence of 5% following ankle fractures treated in a cast, we believe that routine thromboprophylaxis is not justified

Introduction. A recent retrospective study of distal femoral physeal fractures (DFPFs) suggested closed manipulation alone has a high incidence of re-displacement, malunion or physeal bar formation. The paper concluded that all displaced DFPFs require internal fixation, and breaching the physis with k-wires is safe. We agree that hyper-extension/flexion injuries need stabilisation using k-wires but, in our experience, purely valgus/varus deformities can be successfully managed by manipulation under anaesthesia (MUA) and a moulded cylinder cast. Method. We prospectively observed DFPFs presenting over 12 months. Departmental policy is to treat varus/valgus deformities by MUA, with cylinder casting providing 3 point fixation. Hyper-extension/flexion injuries are reduced on a traction table. 2mm cross k-wiring is performed, leaving the wires under the skin, and a cylinder plaster applied. A post-operative CT scanogram accurately assesses limb alignment. Patients are mobilised immediately using crutches and weight-bearing as pain allows. Plaster and k-wires are removed after 4–5 weeks. Scanogram is then repeated, and again at 6 months and 1 year. Results. 17 cases presented over 1 year. 16 were male, with a median age of 15. 13 were injured playing soccer, 1 in a motor vehicle accident and 3 by other mechanisms. Internal fixation supplemented reduction in 13 cases. 1 patient required repeat MUA and k-wiring when post-operative scanogram identified significant varus mal-alignment. In all cases, cylinder casting was unproblematic and range of movement quickly recovered after plaster/wire removal. To date none have developed significant malunion or growth arrest requiring intervention. Conclusion. DFPFs are uncommon, almost always occurring in teenage males. Accurate reduction and stabilisation is vital to restore and maintain a correct mechanical axis. MUA and cylinder casting is adequate in appropriate cases. Early imaging with CT scanogram can detect mal-alignment. Growth arrest is unusual and unlikely to be significant in most patients, who are approaching skeletal maturity. NO DISCLOSURES

The use of percutaneous Kirschner wires [K-wires] and plaster is a popular method of treatment for displaced distal radius fracture. However, multi-database electronic literature review reveals unsurprisingly different views regarding their use. From August 2002 till June 2004, 280 distal radial fractures were admitted to our orthopaedic department. They were recorded prospectively in the departmental trauma admissions database. We studied the 87 cases treated with the K-wires and plaster technique. They were classified according to the AO classification system. The mean patient age was 53 [5-88] years. The mean delay before surgery was 7 [0-24] days. We studied the complications reported by the attending orthopaedic surgical team. 48 out of 87 patients [55.1%] were reported to have complications. We analysed the displacement and the pin tract infection, as they were the main reported complications. 28 out of 87 patients [32%] had displacement [9 had further surgery to correct the displacement, 19 did not have any further surgery as the displacement was accepted]. 11 out of 87 patients [12.6%] had pin tract infection [7 needed early removals of the K-wires and systematic treatment]. Further analysis showed no statistically significant relation between the complications rate and the age of the patients, the delay before surgery or the type of the fractures. We demonstrate a considerable high displacement and infection rate with the use of K-wires and plaster technique for fixation of distal fracture irrespective of the age of the patients, the delay before surgery or the fracture classification. There are other methods for fixation of the distal radial fracture with proven less morbidity which should be considered

Background. Stress fractures at tracker after computer navigated total knee replacement are rare. Periprosthetic fracture after Minimally Invasive Plate Osteosynthesis (MIPO) of stress fracture through femoral tracker is unique in orthopaedic literature. We are reporting this unique presentation of periprosthetic fractures after MIPO for stress fracture involving femoral pin site track in computer assisted total knee arthroplasty, treated by reconstruction nail (PFNA). Methods. A 75-year old female, who had computer navigated right total knee replacement, was admitted 6 weeks later with increasing pain over distal thigh for 3 weeks without trauma. Prior to onset of pain, she achieved a range of movements of 0–105 degrees. Perioperative radiographs did not suggest obvious osteoporosis, pre-existent benign or malignant lesion, or fracture. Radiographs demonstrated transverse fracture of distal third of femur through pin site track. We fixed the fracture with 11-hole combihole locking plate by MIPO technique. Eight weeks later, she was readmitted with periprosthetic fracture through screw hole at the tip of MIPO Plate and treated by Reconstruction Nail (PFNA), removal of locking screws and refixation of intermediate segment with unicortical locking screws. Then she was protected with plaster cylinder for 4 weeks and hinged brace for 2 months. Results. Retrograde nail for navigation pin site stress fracture entails intraarticular approach with attendant risks including scatches to prosthesis and joint infection. So we opted to fix by MIPO technique. Periprosthetic fracture at the top of MIPO merits fixation with antegrade nail in conjunction with conversion of screws in the proximal part of the plate to unicortical locking screws. Overlap of at least 3cms offers biomechanical superiority. She made an uneventful recovery and was started on osteoporosis treatment, pending DEXA scan. Conclusion. Reconstruction Nail (PFNA), refixation of intermediate segment with unicortical locking screws constitutes a logical management option for the unique periprosthetic fracture after MIPO of stress fracture involving femoral pin site track in computer assisted total knee replacement

Aim. We aimed to assess the efficacy of conservative management of proximal phalanx fractures in a plaster slab. Methods. 23 consecutive patients with proximal phalanx fractures were included in this prospective study. The fractures were reduced and the position was held with a dorsal slab for three weeks. They were followed up an average of 7 weeks (range 2 to 45) after the injury. Radiographic confirmation of adequate reduction was carried out each week until union. After removal of the plaster, range of motion of the finger and radiological evidence of union, non-union or malunion was documented. Results. In united fractures, an average angulation of 4° (apex volar) was measured (range 0 to 45°). In one case (45°) this was not acceptable. All other cases measured less than 15° of angulation. On the AP radiograph the angulation was on average 2° (range 0 to 8°). On average 1.3 mm of shortening (range 0 to 5mm) were measured. In one case delayed union with rotational deformity of 20° was evident. After removal of the slab mild stiffness was noted in one case at the metacarpophalangeal joint and in two cases at the proximal interphalangeal joint. Conclusion. Most proximal phalanx fractures can be managed conservatively with acceptable results. NO DISCLOSURES

Aim. The primary aim of multidisciplinary management of diabetic foot disease is limb savage. Difficulty in eradication of infection with systemic antibiotics and obliteration of dead space created by debridement, are two major stumbling blocks in achieving this. Antibiotic loaded bio composites help achieve both these objectives. The aim of this study is to report the early results of antibiotic loaded bio composites in diabetic foot disease. Method. We present early results of 16 patients with diabetic foot disease and osteomyelitis in whom we used antibiotic loaded bio composite (CERAMENT G Bone Support, Lund, Sweden) for local antibiotic delivery and dead space eradication. A multidisciplinary team managed all patients. We performed magnetic resonance and vascular imaging preoperatively and adhered to a strict protocol involving debridement, culture specific systemic antibiotics and dead space obliteration with antibiotic loaded bio composite. The wound was managed with negative pressure wound therapy and all patients were kept non-weight bearing with a plaster back slab or walking boot. Skin cover where required was undertaken by our plastic surgeons. Results. According to the Cierny –Mader Classification 1 patient was type 1, 4 were defined as type 2, 7 were type 3 and 4 were type 4. Seven patients were classed as type B hosts and 9 were type A hosts. At a mean follow up of 38 weeks (26–60) we achieved infection clearance in 14 patients (88%). 10 (63%)wounds healed by secondary intention, 2 had split skin graft, and 1 had primary closure. 2 patients were still on negative pressure wound therapy at final follow-up, one of which has got clearance of infection. One patient is having regular dressings in the community. We had 2 patients who had below knee amputation, one due to significant vascular disease and the other at patient request. Conclusions. A multidisciplinary approach and a strict protocol including augmented debridement and Cerament G injection are effective for treatment of chronic osteomyelitis in diabetic foot disease. The early results with this bio composite antibiotic combination are encouraging

The etiology of the flexion contracture is related to recurrent effusions present in a knee with end-stage degenerative joint disease secondary to the associated inflammatory process. These recurrent effusions cause increased pressure in the knee causing pain and discomfort. Patients will always seek a position of comfort, which is slight flexion. Flexion decreases the painful stimulus by reducing pressure in the knee and relaxing the posterior capsule. Unfortunately, this self-perpetuating process leads to a greater degree of contracture as the disease progresses. Furthermore, patients rarely maintain the knee in full extension. Even during the gait cycle the knee is slightly flexed. As their disease progresses, patients limit their ambulation and are more frequently in a seated position. Patients often report sleeping with a pillow under their knee or in the fetal position. All of these activities increase flexion contracture deformity. Patients with excessive deformity >40 degrees should be counseled regarding procedural complexity and that increasing constraint may be required. Patients are seen preoperatively by a physical therapist and given a pre-arthroplasty conditioning program. Patients with excessive flexion contracture are specifically instructed on stretching techniques, as well as quadriceps rehabilitation exercises. The focus in the postoperative physiotherapy rehabilitation program continues toward the goal of full extension. Patients are instructed in appropriate stretching regimes. Patients are immobilised for the first 24 hours in full extension with plaster splints, such as with a modified Robert Jones dressing. This dressing is removed on postoperative day one. The patient is then placed in a knee immobiliser and instructed to wear it at bed rest, during ambulation and in the evening, only removing for ROM exercises. In cases of severe flexion deformity >30 degrees, patients are maintained in full extension for 3–4 weeks until ROM is begun. Patients are encouraged to use a knee immobiliser for at least the first 6 weeks postoperatively. Treating patients with flexion contracture involves a combination of bone resection and soft tissue balance. One must make every effort to preserve both the femoral and tibial joint line. In flexion contracture the common error is to begin by resecting additional distal femur, which may result in joint line elevation and mid-flexion instability. The distal femoral resection should remove that amount of bone being replaced with metal. Attention should be directed at careful and meticulous balance of the soft tissues and release of the contracted posterior capsule with re-establishment of the posterior recess, which will correct the majority of flexion contractures. Inability to achieve ROM after TKA represents a frustrating complication for both patient and surgeon. Non-operative treatments for the stiff TKA include shoe lift in contralateral limb, stationery bicycle with elevated seat position, extension bracing, topical application of hand-held instruments to areas of soft tissue-dysfunction by a trained physical therapist over several outpatient sessions, and use of a low load stretch device. Manipulation under anesthesia is indicated in patients after TKA having less than 90 degrees ROM after 6 weeks, with no progression or regression in ROM. Other operative treatments range from a downsizing exchange of the polyethylene bearing to revision with a constrained device and low-dose irradiation in cases of severe arthrofibrosis
