Stable fractures of the ankle can be successfully treated non-operatively by a below-knee plaster cast. In some centres, patients with this injury are routinely administered low-molecular-weight heparin, to reduce the risk of deep-vein thrombosis (DVT). We have assessed the incidence of DVT in 100 patients in the absence of any thromboprophylaxis. A colour Doppler duplex ultrasound scan was done at the time of the removal of the cast. Five patients did develop DVT, though none had clinical signs suggestive of it. One case involved the femoral and another the popliteal vein. No patient developed pulmonary embolism. As the incidence of DVT after ankle fractures is low, we do not recommend routine thromboprophylaxis

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

We have had experience of an 18-month-old boy with a cardiomyopathy who died a few minutes after removal of his cast with a saw, apparently from a malignant cardiac arrhythmia triggered by anxiety. We therefore examined the anxiety reaction to this method of removal of a plaster cast in 20 healthy children; ten were provided with hearing protectors and ten were not. The level of anxiety was assessed by measuring the heart rate, a known physiological indicator of anxiety, before, during and five minutes after removal of the cast. The noise level was also measured. The results showed a mean increase in heart rate during the procedure of 27.9 beats per minute (bpm) (26.9%) in the children with no hearing protectors and 10.4 bpm (11.1%) in children who used hearing protectors (p < 0.001). Five minutes after the procedure the heart rate had returned to the baseline rate in all patients. We recommend that hearing protectors should be used in children undergoing removal of a plaster cast to decrease the anxiety reaction. If possible, clinicians should avoid the use of a saw for this purpose in children with a cardiomyopathy

Introduction and objectives: The most commonly used treatment for extraarticular fractures of distal radius is closed reduction and maintenance of reduction in a cast. Two types of casts are used: plaster splint for 7–10 days and later exchanged to a circular cast and the use of circular cast immediately. The objective of this work is to compare both types of treatment in terms of ability to achieve reduction and to maintain it during healing. Methods: A prospective, randomized and blinded study was designed. To date, 21 patients enrolled the study. Informed consent was given. The inclusion criteria were: older than 35 years, extraarticular distal radius fracture sustained less than 24 hours before and not previously treated. Exclusion criteria included previous injury in the same wrist, open fracture, and not compliance with the protocol. After intrafocal anesthesia with mepivacaine 1%, fracture was reduced under traction and immobilized in a dorsal short plaster splint (splint group) or a circular short plaster cast (circular group) randomly. After 10 days of immobilization, the plaster splint was changed to a circular short plaster cast. AP and lateral X-Rays were taken before reduction, after reduction, after 10 days (before changing cast), and at 21 days. Volar inclination of lunate fossa on the lateral X-Ray was obtained. On the AP proyection, the radial inclination and radial length was measured. Complications were recorded. Data was analysed through ANOVA between groups. Results: When comparing X-rays before and after reduction, the volar inclination of the lunate fossa on lateral projection changed from −21,4° to 8,60° (30° change) after reduction in splint group and from −15,22° to 1,78° (17° change) in circular group (p< 0.05). The other comparisons were N.S. When comparing after reduction and 10 days later, the radial inclination changed from 20,20° to 18,80° (1,40° change) in the splint group and from 20,89° to 20,44 (0,44° change) in the circular group (p< 0.05). Other comparisons were N.S. No differences were found between 10 days and 21 days in any X-Ray parameter. No complications were found. Conclusions: A better reduction was achieved with the plaster splint method in the immediate X-Ray control. Nevertheless, reduction was better maintained during the first 10 days with the circular plaster cast method

Aim: A prospective randomised clinical trial was performed to evaluate two forms of immobilisation in the treatment of colles fractures not requiring manipulation. Methods: Patients were randomised to either plaster cast (PC) or a removable splint: wrist splint (FWS) according to date of presentation. Patients who had associated injuries to the same upper limb, previous wrist fracture, and open fractures, below 20 years or impaired cognitive function were excluded. The hospital ethical committee approved the study and informed consent was obtained from patients. Patients were reviewed at one week, two weeks, six weeks and twelve weeks following enrolment into the trial. Radiographs were performed on the first four visits. Subjective data was obtained using a patient questionnaire. Levels of pain, comfort in cast, swelling and any modifications to the cast were documented. Was used at six and twelve weeks to assess Clinical assessment was performed by a qualified physiotherapist using the demerit score of Sarmiento which combines range of motion, grip strength and functional assessment. Results: There were thirty-seven patients in the PC group and thirty-four in the FWS group. They were well matched in terms of age and sex distribution One patient in the PC group required manipulation under anaesthesia due to loss of position at one week. There was no statistical difference between either treatment method in radiological position. Nine patients in the PC group required change of cast due to loosening or discomfort. A further eight patients in the PC group required cast trimming. Visual analogue scores for pain and cast discomfort were lower in the FS group (p< 0.05). Grip strength compared to the opposite side was higher in the FS group (55.9% Vs 47.8% at week six, 71.8% Vs 65% at week twelve). Functional assessment demonstrated a higher score in the FS group at six weeks. However the difference did not reach statistical significance at repeat examination at twelve weeks. Conclusion: In this study there was no difference in either method in maintaining fracture position. However there was greater patient satisfaction and earlier rehabilitation in those patients treated in a futura wrist splint. Patients treated in plaster cast required a greater use of plaster room resources. We feel that the use of a removable wrist splint in suitable patients with either undisplaced or minimally displaced distal radial fractures is validated by this study

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

The use of Orthoplast cast-bracing to allow early hand function in the treatment of displaced Colles' fractures was investigated in 243 patients. They were randomly allocated into three groups: in the first a conventional Colles' type plaster was used; in the second an above-elbow cast-brace with the forearm in supination; and in the third a below-elbow cast-brace. Radiographic measurements were made at each stage of treatment, and the final anatomical result was scored using Sarmiento's (1975) criteria. Function was assessed at three months and at six months. The anatomical result was not influenced by the method of immobilisation but was related to the efficacy of reduction. Loss of position in the braces was no greater than in plaster. The functional result at three months also was uninfluenced by the method of immobilisation; it was, however, related to the severity of the initial displacement, and (to a lesser degree) to the anatomical result, an effect which was lost at six months. Early hand function and the supinated position advocated by Sarmiento were found to confer no anatomical or functional advantage; we could see no reason to change from the use of conventional plaster casts in the treatment of uncomplicated Colles' fractures

Introduction. Venous thromboembolism (VTE) is a significant cause of patient morbidity and mortality, the risk of which increases in orthopaedic patients with lower limb immobilisation. This incidence should in theory reduce if the patients are ambulatory early in the treatment phase. The aim of this study was, therefore, to identify a difference in the incidence of symptomatic VTE by treating acute Achilles tendon rupture patients with conventional non-weight bearing plaster versus functional weight bearing mobilisation. Methodology. The notes of 91 consecutive patients with acute Achilles tendon rupture were retrospectively reviewed and prospectively followed. The patients' demographics, treatment modality (non-weight bearing plaster versus weight bearing boot), and the type of plaster immobilisation was compared to assess whether they affect the incidence of clinical VTE. The predisposing risk factors were also analysed between the treatment groups. Out of 91 patients, 50 patients with acute Achilles tendon rupture were treated conservatively in a conventional non-weight bearing immobilisation cast. From these 50 patients, 3 then underwent surgery and were therefore excluded from the results. On the other hand, 41 patients were treated with functional weight bearing mobilisation (Vacupad). Patients who did have a symptomatic thromboembolic event also had an ultrasound scan to confirm a deep vein thrombosis of the lower limb or a CT-scan to confirm pulmonary embolism. Results. Out of the 47 patients who were treated conservatively in a non-weight bearing plaster cast, 9 patients had a thromboembolic event (19.1%). On the other hand, out of the 41 patients who were treated with functional weight bearing mobilisation, only 2 patients had a symptomatic thromboembolic event (4.2%). This was statistically significant (p=0.012). This shows that patients who are treated in a non-weight bearing plaster have about five times increased risk of developing a sypmptomatic VTE compared to those treated by functional weight bearing mobilisation. There was however no difference in the predisposing factors in patients who developed VTE compared to those who did not. Conclusion. The incidence of symptomatic VTE after acute Achilles tendon rupture is high and under-recognised. Asymptomatic VTE after this injury is probably even higher. There is a significant decrease in the clinical incidence of thromboembolic events in patients treated conservatively with early mobilisation in the functional weight bearing boot compared to those treated in a non-weight bearing cast. There is a need for further research to define the possible benefit of thromboprophylaxis in patients treated by non-weight bearing plasters

Introduction. Peri prosthetic fracture is a recognised complication following Total ankle arthroplasty (TAA). There is limited literature on post operative management following TAA and controversies exist based on surgeon preferences. This project reports the incidence of peri- prosthetic fractures in patients managed with 2 different post-operative protocols. Materials and Methods. Patients undergoing primary TAA with a diagnosis of Osteoarthritis (OA) or Post-traumatic Osteoarthritis (PTOA) were recruited into a randomized controlled trial. These patients did not require any additional procedures. Patients were consented for the trial and randomized to one of two treatment groups (Early mobilisation after surgery vs. immobilisation in a plaster cast for 6 weeks post operatively). Plaster group patients underwent a graduated physiotherapy program from 6-12 weeks and early mobilisation group patients from 1-12 weeks. Complications any were recorded at 2, 4, 6 and 12 weeks post-operatively. Results. A total of 16 ankle replacements were done for a diagnosis of OA (10) and PTOA (6). Mean age was 58 years (±11.75) for the plaster group and 64 years (± 9.32) for the early mobilisation group. 7 patients were randomized to the plaster group and 9 patients were randomized to the early mobilisation group. Of the plaster group 1 patient sustained an intra-operative fracture tibia and 2 patients reported with a fractured medial malleolus. Of the early mobilisation group, 1 patient reported with a peri prosthetic fracture tibia at 6 weeks and 3 patients reported a fractured medial malleolus at 3 months follow up. The percentage of fracture incidence between plaster versus early immobilisation group was 42.8% and 44.4 % respectively. Conclusions. These early results demonstrate no significant differences in the incidence of fracture rates between groups. Further studies of post-operative management are needed to study the correlation with peri-prosthetic fracture rates after TAA

Introduction/Aim. Thromboembolism is a significant cause of patient morbidity and mortality, the risk of which increases in orthopaedic patients with lower limb immobilisation. It was therefore, our aim to identify a difference in symptomatic thromboembolism by treating acute Achilles tendon rupture patients with conventional non-weight bearing plaster versus functional weight bearing mobilisation. Methodology. The notes of 91 consecutive patients with acute Achilles tendon rupture were reviewed. The patients demographics, treatment modality (non-weight bearing plaster versus weight bearing boot), and predisposing risk factors were analysed. From the 91 patients, 50 patients with acute Achilles tendon rupture were treated conservatively in a non-weight bearing immobilisation cast. From these 50 patients, 3 then underwent surgery and were therefore excluded from the results. 41 patients were treated with functional weight bearing mobilisation. Patients who did have a symptomatic thromboembolic event had an ultrasound scan to confirm a deep vein thrombosis of the lower limb, or a CT-scan to confirm pulmonary embolism. Results. Out of the 47 patients who were treated conservatively in a non-weight bearing plaster cast, 9 patients (19.1 %) had a thromboembolic event. Out of the 41 patients who were treated with functional weight bearing mobilisation, 2 patients (4.8%) had a thromboembolic event. Thus, patients who were treated in a non-weight bearing plaster had a significantly higher risk of developing thromboembolism (p value of <0.05) and an increased risk ratio of 24% compared to those who were treated with functional weight bearing mobilisation. Conclusion. There is a significant decrease in the clinical incidence of thromboembolic events in patients treated conservatively with early mobilisation in the functional weight bearing boot compared to those treated in a non-weight bearing cast

Rockers are applied to lower limb casts to assist walking but there is little information on their biomechanical effects. The performances of 10 commercially available rockers were compared. They were applied to a below-knee cast worn by a normal subject who was also tested walking in the cast alone. Gait analysis was used to evaluate kinematic and kinetic data. The design of rocker had no effect upon the kinematics of walking. However, using new criteria for kinetic assessment of rocker function (tibial floor angular velocity and centre of pressure progression), most designs had a deleterious effect on the biomechanics of gait. Only two rockers approached the ideal kinetic criteria.

Aim

To demonstrate the effect of location of the split of the plaster on the raised intercompartmental pressure in the volar and dorsal compartments.

The aim of this study was to assess the usefulness of Cast index and an indigenously developed Gap index as measures of poor moulding of plaster. 20 cases of re-manipulation of distal third forearm fractures excluding growth plate injuries were compared with a control of 80 patients. 5 patients in the control group had an axial deviation of more than 10 degrees but were not remanipulated and therefore were included in the failure group. The gap index and the cast index of the two groups was compared as predictors of failure of conservative treatment. The groups were similar in terms of demography and post reduction alignment. There was a significant difference (< 0.001) in the Cast index and the Gap index of both the groups. The sensitivity of the Cast index (> 0.8) in predicting failure of plaster was 48% while that of the sum of Gap index (> 0.15) in AP & Lat view was 88%. Gap index was found to be more accurate (84%) than Cast index (78%) in predicting failure. The gap index is a better predictor of failure than the cast index. A quick assessment of these indices, especially by the less experienced surgeons, is a good practice before accepting any plaster following a manipulation of distal radial fractures. It would not only save the patient a second anaesthesia but also complications of a more extensive second procedure and of course hospital resources.

Introduction: We aimed to assess a simple radiological method of predicting redisplacement of paediatric forearm fractures. The Cast Index (CI) is the ratio of sagittal to coronal width from the inside edges of the cast at the fracture site. A CI of > 0.7 was used as the standard in predicting fracture redisplacement. The cast index has previously been validated in an experimental study.

Methods: Case records and radiographs of 1001 children who underwent a manipulation under general anaesthesia for a displaced fracture of the distal forearm were studied. Redisplacement was defined as more than 15 degrees of angulation and/or more than 80 percent of translational displacement on check radiographs at 2 weeks. Angulation (in degrees) and translation displacement (in percentage) were measured on the initial and check radiographs. The CI was measured on postoperative radiographs.

Results: Fracture redisplacement was seen in 107 cases at 2 week follow up. Of the 752 patients (75%) with a CI of less than 0.7 the displacement rate was 5.58%. Of the 249 patients (25%) with a CI greater than 0.7 the redisplacement rate was 26%. The CI was significantly higher in the redisplacement group. No statistically significant difference was seen for age, sex or ethnicity. Nor were statistical differences noted in initial angular deformity, initial displacement and seniority of the surgeon. Good intra and inter observer reproducibility was observed. There was no statistical difference in patients with a cast index between 0.7 and 0.8.

Conclusion: The cast index is a simple and reliable radiographic measurement to predict the redisplacement of forearm fractures in children. Previous studies have used a CI of > 0.7 as the predictor of redisplacement although this study suggests a plaster with a CI of < 0.81 is acceptable. A high cast index is associated with redisplacement of fractures and should therefore be considered when moulding casts in distal forearm fractures.

We aimed to assess a simple radiological method of predicting redisplacement of paediatric forearm fractures. The Cast Index (CI) is the ratio of sagittal to coronal width from the inside edges of the cast at the fracture site. CI of 0.7 was used as the benchmark in predicting fracture redisplacement. Case records and radiographs of 1001 children who underwent a manipulation under general anaesthesia for a displaced fracture of the distal forearm were studied. Redisplacement was defined as more than 15 degrees of angulation and/or more than 80 percent of translational displacement on check radiographs at 2 weeks. Angulation (in degrees) and translation displacement (in percentage) were measured on the initial and check radiographs. The Cast index was measured on the check radiographs. Good intra and inter observer reproducibility was observed for both these measurements. The cast index has been previously validated in an experimental study.

The adequacy of reduction after manipulation was estimated by the postreduction translation and angulation of the radius and ulna in anteroposterior and lateral plain film radiographs. The 1001 patients who qualified for the study, fracture redisplacement was seen in 107 cases at the all important two week follow up. Seven hundred and fifty-two patients had cast indices of 0.8 or less whilst 249 had casting indices of 0.81 or more. In patients with cast indices of 0.8 or less, the displacement rate was only 5.58%. However, in patients with cast indices of 0.81 or more, the displacement rate was 26%. Initial displacement, angulation and the post manipulation cast index were the three factors which were significantly higher in the redisplacement group.

No statistically significant difference was seen for age, sex or ethnicity. Nor were statistical differences noted in initial angular deformity, initial displacement and seniority of the surgeon. There was no statistical difference in patients with cast indices between 0.7 and 0.8.

Cast index is a simple reliable radiographic measurement to predict the redisplacement of forearm fractures in children. A plaster with a CI of > 0.81 is prone to redisplacement. A high cast index is associated with redisplacement of fractures and should therefore be considered when moulding casts is distal forearm fractures.

We hypothesised that adjuvant intermittent pneumatic compression (IPC) beneath a plaster cast would reduce the risk of deep-vein thrombosis (DVT) during post-operative immobilisation of the lower limb. Of 87 patients with acute tendo Achillis (TA) rupture, 26 were prospectively randomised post-operatively after open TA repair. The treatment group (n = 14) received two weeks of IPC of the foot for at least six hours daily under a plaster cast. The control group (n = 12) had no additional treatment. At two weeks post-operatively all patients received an orthosis until follow-up at six weeks. At two and six weeks the incidence of DVT was assessed using colour duplex sonography by two ultrasonographers blinded to the treatment. Two patients withdrew from the study due to inability to tolerate IPC treatment. An interim analysis demonstrated a high incidence of DVT in both the IPC group (9 of 12, 75%) and the controls (6 of 12, 50%) (p = 0.18). No significant differences in incidence were detected at two (p = 0.33) or six weeks (p = 0.08) post-operatively. Malfunction of the IPC leading to a second plaster cast was found to correlate with an increased DVT risk at two weeks (φ = 0.71; p = 0.019), leading to a premature abandonment of the study. We cannot recommend adjuvant treatment with foot IPC under a plaster cast for outpatient DVT prevention during post-operative immobilisation, owing to a high incidence of DVT related to malfunctioning of this type of IPC application.

Only 10–15% of those thought clinically to have a fractured scaphoid are confirmed as having fractures on initial radiographs. A further 1–20% of those who had initially negative radiographs go on to have fractures confirmed on subsequent radiographs taken 10–14 days later.

Fifty patients initially considered clinically to have scaphoid fractures were identified: 32 females and 18 males, with a mean age of 32 years, range 10–88 years, 68% were noted to have injured their dominant hand. Four patients, (8%), had scaphoid fractures identified on initial radiographs and only 1 patient, (2%), was found to have an occult scaphoid later. Three patients were found to have other bony injuries leaving 42 patients, (84%), having no fracture identified. Thirty-eight of this final group could be contacted and completed telephone questionnaires. The remaining 4 were lost to follow up. Patients were asked questions about employment, time off work, interference with other activities and general satisfaction with treatment.

The mean time in plaster was 16 days, range 9–42 days. Eighteen of those in work, (47% of the total, 66.7% of the workers), had time off work. The mean length of time off work was 18.4 days, range 14–42 days. Sixteen of these received full “sick pay” for their time off. Personal hygiene was affected in 84%, housework in 37.5%, sports/hobbies for 55%, driving in 76% and social activities in 11.8%. Only 2 patients overall, suffered personal financial loss which amounted to less than one hundred pounds each.

Only 3 people, (8%), expressed dissatisfaction with their management when directly questioned. All patients would have preferred an immediate diagnosis had this been possible. Alternative to this treatment including bone scanning and MRI are discussed.

Objectives. We aimed to examine the characteristics of deep venous flow in the leg in a cast and the effects of a wearable neuromuscular stimulator (geko; FirstKind Ltd) and also to explore the participants’ tolerance of the stimulator. Methods. This is an open-label physiological study on ten healthy volunteers. Duplex ultrasonography of the superficial femoral vein measured normal flow and cross-sectional area in the standing and supine positions (with the lower limb initially horizontal and then elevated). Flow measurements were repeated during activation of the geko stimulator placed over the peroneal nerve. The process was repeated after the application of a below-knee cast. Participants evaluated discomfort using a questionnaire (verbal rating score) and a scoring index (visual analogue scale). Results. The geko device was effective in significantly increasing venous blood flow in the lower limb both with a plaster cast (mean difference 11.5 cm/sec. -1. ; p = 0.001 to 0.13) and without a plaster cast (mean difference 7.7 cm/sec. -1. ; p = 0.001 to 0.75). Posture also had a significant effect on peak venous blood flow when the cast was on and the geko inactive (p = 0.003 to 0.69), although these differences were less pronounced than the effect of the geko (mean difference 3.1 cm/sec. -1. (-6.5 to 10)). The geko device was well tolerated, with participants generally reporting only mild discomfort using the device. Conclusion. The geko device increases venous blood flow in the lower limb, offering a potential mechanical thromboprolylaxis for patients in a cast. Cite this article: Bone Joint Res 2013;2:179–85

Aims. The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture. Methods. This is a secondary analysis of a multicentre randomized controlled trial comparing adults with an acute ankle fracture, initially managed either by operative or nonoperative care. Patients were randomly allocated to receive either a cast immobilization or a fixed-angle removable orthosis (removable brace). Data were collected on baseline characteristics, ankle function, quality of life, and complications. The Olerud-Molander Ankle Score (OMAS) was the primary outcome which was used to measure the participant’s ankle function. The primary endpoint was at 16 weeks, with longer-term follow-up at 24 weeks and two years. Results. Overall, 436 patients (65%) completed the final two-year follow-up. The mean difference in OMAS at two years was -0.3 points favouring the plaster cast (95% confidence interval -3.9 to 3.4), indicating no statistically significant difference between the interventions. There was no evidence of differences in patient quality of life (measured using the EuroQol five-dimension five-level questionnaire) or Disability Rating Index. Conclusion. This study demonstrated that patients treated with a removable brace had similar outcomes to those treated with a plaster cast in the first two years after injury. A removable brace is an effective alternative to traditional immobilization in a plaster cast for patients with an ankle fracture. Cite this article: Bone Joint J 2023;105-B(4):382–388

The purpose of this study was to investigate the effects of right leg restriction at the knee, ankle or both, on a driver’s braking times. Previous studies have not investigated the effects of knee restriction on braking performance. A total of 23 healthy drivers performed a series of emergency braking tests in a driving simulator in either an above-knee plaster cast, a below-knee cast, or in a knee brace with an increasing range of restriction. The study showed that total braking reaction time was significantly longer when wearing an above-knee plaster cast, a below-knee plaster cast or a knee brace fixed at 0°, compared with braking normally (p < 0.001). Increases in the time taken to move the foot from the accelerator to the brake accounted for some of the increase in the total braking reaction time. Unexpectedly, thinking time also increased with the level of restriction (p < 0.001). The increase in braking time with an above-knee plaster cast in this study would increase the stopping distance at 30 miles per hour by almost 3 m. These results suggest that all patients wearing any lower-limb plaster cast or knee brace are significantly impaired in their ability to perform an emergency stop. We suggest changes to the legislation to prevent patients from driving with lower-limb plaster casts or knee braces

Aims. To explore individuals’ experience of a scaphoid waist fracture and its subsequent treatment. Methods. A purposive sample was created, consisting of 49 participants in the Scaphoid Waist Internal Fixation for Fractures Trial of initial surgery compared with plaster cast treatment for fractures of the scaphoid waist. The majority of participants were male (35/49) and more younger participants (28/49 aged under 30 years) were included. Participants were interviewed six weeks or 52 weeks post-recruitment to the trial, or at both timepoints. Interviews were semistructured and analyzed inductively to generate cross-cutting themes that typify experience of the injury and views upon the treatment options. Results. Data show that individual circumstances might exaggerate or mitigate the limitations associated with a scaphoid fracture, and that an individual’s sense of recovery is subjective and more closely aligned with perceived functional abilities than it is with bone union. Misconceptions that surgery promises a speedier and more secure form of recovery means that some individuals, whose circumstances prescribe a need for quick return to function, express a preference for this treatment modality. Clinical consultations need to negotiate the imperfect relationship between bone union, normal function, and an individual’s sense of recovery. Enhancing patients’ perceptions of regaining function, with removable splints and encouraging home exercise, will support satisfaction with care and discourage premature risk-taking. Conclusion. Clinical decision-making in the management of scaphoid fractures should recognize that personal circumstances will influence how functional limitations are experienced. It should also recognize that function overrides a concern for bone union, and that the consequences of fractures are poorly understood. Where possible, clinicians should reinforce in individuals a sense that they are making progress in their recovery. Cite this article: Bone Jt Open 2022;3(8):641–647

Aims. The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury. Methods. Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient’s initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed. Results. Patients treated with surgical fixation with wires had less dorsal angulation of the radius versus those treated in a moulded cast at six weeks after manipulation of the fracture; the mean difference of -4.13° was statistically significant (95% confidence interval 5.82 to -2.45). There was no evidence of a difference in radial shortening. However, there was no correlation between these radiological measurements and PROMs at any timepoint in the 12 months post-injury. Conclusion. For patients with a dorsally displaced distal radius fracture treated with a closed manipulation, surgical fixation with wires leads to less dorsal angulation on radiographs at six weeks compared with patients treated in a moulded plaster cast alone. However, the difference in dorsal angulation was small and did not correlate with patient-reported pain and function. Cite this article: Bone Jt Open 2024;5(2):132–138

Objectives. The evidence base to inform the management of Achilles tendon rupture is sparse. The objectives of this research were to establish what current practice is in the United Kingdom and explore clinicians’ views on proposed further research in this area. This study was registered with the ISRCTN (ISRCTN68273773) as part of a larger programme of research. Methods. We report an online survey of current practice in the United Kingdom, approved by the British Orthopaedic Foot and Ankle Society and completed by 181 of its members. A total of ten of these respondents were invited for a subsequent one-to-one interview to explore clinician views on proposed further research in this area. Results. The survey showed wide variations in practice, with patients being managed in plaster cast alone (13%), plaster cast followed by orthoses management (68%), and orthoses alone (19%). Within these categories, further variation existed regarding the individual rehabilitation facets, such as the length of time worn, the foot position within them and weight-bearing status. The subsequent interviews reflected this clinical uncertainty and the pressing need for definitive research. Conclusions. The gap in evidence in this area has resulted in practice in the United Kingdom becoming varied and based on individual opinion. Future high-quality randomised trials on this subject are supported by the clinical community. Cite this article: Bone Joint Res 2015;4:65–9

Aim. The purpose of this study was to investigate the effects of plaster/splint immobilisation of the knee/ankle on driving performance in healthy individuals. Methods & Materials. Twenty-three healthy drivers performed a series of emergency brake tests in a driving simulator having applied above knee plaster casts, below knee plaster casts, or a knee brace with increasing restriction. Results. Our study showed that compared to braking normally, total brake reaction time was significantly longer when wearing an above knee plaster cast, below knee plaster cast or a knee brace with zero degrees of freedom (p<0.001). Increases in movement time from accelerator to brake accounted for some of the increase in the total brake reaction time. However, unexpectedly thinking time also increased with the level of restriction (p<0.001). Conclusion. These results suggest that all patients wearing a plaster cast or knee brace are significantly impaired in their ability to perform an emergency stop. We suggest changes to the legislation that prevents patients driving with lower limb plaster casts or knee braces

Aims. Displaced distal radius fractures were investigated at a level 1 major trauma centre during the COVID-19 2020 lockdown due to the implementation of temporary changes in practice. The primary aim was to establish if follow-up at one week in place of the 72-hour British Orthopaedic Association Standards for Trauma & Orthopaedics (BOAST) guidance was safe following manipulation under anaesthetic. A parallel adaptation during lockdown was the non-expectation of Bier’s block. The secondary aim was to compare clinical outcomes with respect to block type. Methods. Overall, 90 patients were assessed in a cross-sectional cohort study using a mixed, retrospective-prospective approach. Consecutive sampling of 30 patients pre-lockdown (P1), 30 during lockdown (P2), and 30 during post-lockdown (P3) was applied. Type of block, operative status, follow-up, and complications were extracted. Primary endpoints were early complications (≤ one week). Secondary endpoints were later complications including malunion, delayed union or osteotomy. Results. In P1, 86.6% of patients were seen between days one to three, 26.7% in P2, and 56.7% in P3. There were no documented complications from days one to three. Operative rate was 35.5%, which did not vary significantly (p= 0.712). Primary endpoints occurred between day four to seven, and included one patient each period treated for plaster cast pain. Secondary endpoints in P1 included delayed union (one patient). During P2, this included malunion (one patient), a pressure sore (one patient) and ulnar cutaneous nerve symptoms (two patients). In P3, malunion was identified in one patient. Mean follow-up was six months (4 to 9) with union rate 96%. Change in block practice varied significantly (p =＜0.05). The risk ratio of complications using regional block (Bier’s) over haematoma block was 0.65. Conclusion. Follow-up adaptations during lockdown did not adversely affect patient outcomes. Regional anaesthesia is gold standard for manipulation of displaced distal radial fractures. Cite this article: Bone Jt Open 2021;2(5):338–343

Aims. Describe a statistical and economic analysis plan for the Distal Radius Acute Fracture Fixation Trial 2 (DRAFFT2) randomized controlled trial. Methods. DRAFFT2 is a multicentre, parallel, two-arm randomized controlled trial. It compares surgical fixation with K-wires versus plaster cast in adult patients who have sustained a dorsally displaced fracture of the distal radius. The primary outcome measure is the Patient-Rated Wrist Evaluation (PRWE, a validated assessment of wrist function and pain) at 12 months post-randomization. Secondary outcomes are measured at three, six, and 12 months after randomization and include the PWRE, EuroQoL EQ-5D-5L index and EQ-VAS (visual analogue scale), complication rate, and cost-effectiveness of the treatment. Results. This paper describes the full details of the planned methods of analysis and descriptive statistics. The DRAFFT2 study protocol has been published previously. Conclusion. The planned analysis strategy described records our intent to conduct statistical and within-trial cost-utility analyses. Cite this article: Bone Joint Open 2020;1-6:245–252

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

Aims. The Ponseti method is an effective evidence-based treatment for clubfoot. It uses gentle manipulation to adjust the position of the foot in serial treatments towards a more physiological position. Casting is used to hold the newly achieved position. At first, the foot resists the new position imposed by the plaster cast, pressing against the cast, but over time the tissues are expected to adapt to the new position and the force decreases. The aim of this study was to test this hypothesis by measuring the forces between a clubfoot and the cast during treatment with the Ponseti method. Patients and Methods. Force measurements were made during the treatment of ten idiopathic clubfeet. The mean age of the patients was seven days (2 to 30); there were nine boys and one girl. Force data were collected for several weeks at the location of the first metatarsal and the talar neck to determine the adaptation rate of the clubfoot. Results. In all measurements, the force decreased over time. The median (interquartile range) half-life time was determined to be at 26 minutes (20 to 53) for the first metatarsal and 22 minutes (9 to 56) for the talar neck, suggesting that the tissues of the clubfoot adapt to the new position within several hours. Conclusion. This is the first study to provide objective force data that support the hypothesis of adaptation of the idiopathic clubfoot to the new position imposed by the cast. We showed that the expected decrease in corrective force over time does indeed exist and adaptation occurs after a relatively short period of time. The rapid reduction in the forces acting on the foot during treatment with the Ponseti method may allow significant reductions in the interval between treatments compared with the generally accepted period of one week

The initial treatment of the congenital clubfoot is still a debated subject among different schools. We report our current experience with Ponseti method. Materials and Methods: From April 1999 to May 2001 we have consecutively treated with this method 80 idiopathic clubfeet of 57 children put under treatment at neo-natal period. Progressive correction of the deformity has been obtained with 7 toe-to-groin plaster casts changed weekly. When complete derotation of the hind-foot and forefoot has been reached, subcutaneus tenotomy of the tendon Achilles has been performed. At the end of this first period, the feet have been adapted in Denis Browne splint, worn full time for four months and thereafter just at night. The feet have been evaluated clinically (score of Dimeglio and Bensahel), radiologically and some with MRI. Results: Whole correction of the deformity at the end of treatment with plaster casts, has been achieved for 71 times. When the plaster casts are removed, the talocalcaneal divergence, on antero-posterior and lateral views and the tibial-calcaneal angle (x-ray in maximum dorsal flexion ), were respectively, as an average of 20; 30,7; 21,9 degrees. At an average of 20 months follow up, 54 feet of 80 had a score of 0 or 1 of 20, and 14 had a score of 2; on radiological aspect the talo-calcaneal divergence in antero-posterior and lateral views and the tibial-calcaneal angle were respectively as an average of 29; 24,5; 14 degrees. At this evaluation the percentage of relapses of the deformity was 20% (17 cases). All the relapses have been treated again in plaster casts with 40% of success. So far, only four medial release operations have been necessary. Six feet benefited by the transfer of the tibialis anterior tendon to the third cuneiform and slight medial release. Discussion and Conclusion: The Ponseti’s method presents several advantages: high quality reduction of the clubfoot with the restoration of a “sub-normal” anatomy, low cost and small displeasing worry for the parents, with this method the functional re-education does not seem to improve the quality of results. The prevention of the relapse goes by good compliance to the splint

Statement of purpose:. A randomised clinical trial was undertaken to find out if treatment time and failure rate in children treated by the Ponseti method differed between below-knee vs above-knee cast groups. Methods and Results:. Eligible children with idiopathic clubfoot, treated using the Ponseti method, were randomised to either below knee or above knee plaster of Paris casting. Outcome measures were total treatment time and the occurrence of failure, defined as two slippages or a treatment time above eight weeks. Twenty-six children (33 feet) were entered into the trial, with a mean age of 17 days (range 1–40) in the above knee and 11 days (range 5–20) in the below knee group. Because of six failures in the below knee group (38%), the trial was stopped early for ethical reasons. Failure rate was significantly higher in the below-knee group (P 0.039). The median treatment times of six weeks in the below knee and four weeks in the above knee group differed significantly (P 0.01). Statement of conclusion:. Below knee plaster of Paris casts in conjunction with the Ponseti method showed significantly higher rates of failure than above knee plaster casts, requiring conversion to above knee casts, and a significantly longer treatment time. This higher rate of failure of below knee casts forced an early end of the trial. This study shows that a well moulded above knee plaster cast is safe and superior to a below knee plaster cast in conjunction with the Ponseti method. We do not believe that modifying the original Ponseti method in this manner is beneficial. Level of evidence: I

In 1991 15% of the UK population that travelled abroad required medical assistance. We have been treating more patients with lower limb injuries requiring repatriation via aircraft. Recommendations from Airlines were unavailable. 357 Consultants replied to a questionnaire about transportation of patients with a lower limb injury wearing a plaster cast. There was no consensus on safe transportation of these patients. No scientific data is available on the dynamics of transportation of patients with lower limb trauma. In order to assess the safest method of transportation an experiment was conducted. Ethical committee approval was granted. Five volunteers wearing above leg plaster casts were placed in a decompression chamber. The effects on anterior compartment pressures, Doppler venous return, ambient pressure between plaster and skin were assessed in different positions with and without plasters being split. In the normal population we have shown a trebling of intracompartmental pressures from an average of under 10mmHg to 30mmHg. Intracompartmental pressures are more raised with 90 degrees of hip flexion rather than 45 degrees. We recommend patients be transferred with their legs at 45 degrees to the ground with a split plaster cast

Deep vein thrombosis is a common complication of immobilising the lower limb after surgery. We hypothesised that intermittent pneumatic compression (IPC) therapy in outpatients who had undergone surgical repair of acute ruptures of the Achilles tendon could reduce the incidence of this problem. A total of 150 patients who had undergone surgical repair of the Achilles tendon were randomised to either treatment with IPC for six hours per day (n = 74) under an orthosis or treatment as usual (n = 74) in a plaster cast without IPC. At two weeks post-operatively, the incidence of deep vein thrombosis was assessed using blinded, double-reported compression duplex ultrasound. At this point, IPC was discontinued and all patients were immobilised in an orthosis for a further four weeks. At six weeks post-operatively, a second compression duplex ultrasound scan was performed. At two weeks, the incidence of deep vein thrombosis was 21% in the treated group and 37% in the control group (p = 0.042). Age over 39 years was found to be a strong risk factor for deep vein thrombosis (odds ratio (OR) = 4.84, 95% confidence interval (CI) 2.14 to 10.96). Treatment with IPC, corrected for age differences between groups, reduced the risk of deep vein thrombosis at the two-week point (OR = 2.60; 95% CI 1.15 to 5.91; p =0.022). At six weeks, the incidence of deep vein thrombosis was 52% in the treated group and 48% in the control group (OR 0.94, 95% CI 0.49 to 1.83). IPC appears to be an effective method of reducing the risk of deep vein thrombosis in the early stages of post-operative immobilisation of outpatients. Further research is necessary to elucidate whether it can confer similar benefits over longer periods of immobilisation and in a more heterogeneous group of patients.

We describe a direct method of measuring the tightness of plaster casts. Tightness was measured weekly in 23 consecutive patients with Colles' fractures. Six had objective signs of algodystrophy nine weeks after the fracture. In these patients the plaster cast was significantly tighter during the first three weeks than in patients who did not develop algodystrophy. The complex relationship between these findings is discussed

Introduction. Displaced distal radius fractures in children have been treated in above elbow plaster casts since the last century. Cast index has been calculated previously, which is a measure of the sagittal cast width divided by the coronal cast width measurement at the fracture site. This indicates how well the cast was moulded to the contours of the forearm. We retrospectively analysed the cast index in post manipulation radiographs to evaluate its relevance in redisplacement or reangulation of distal forearm fractures. Study Design. Consecutive radiographic analysis. Materials and methods. 156 consecutive paediatric patients (114M : 42F), with a mean age of 9.8 years (range 2-15 years), presenting with forearm fractures were studied. All patients were manipulated in OR and a moulded above elbow cast was applied. The cast index was measured on immediate post manipulation radiographs. Results. Displacement of the fracture within the original plaster cast occurred in 30 patients (19%), 22/114 males; 8/42 females. The cast index in the 30 patients requiring a second procedure (mean 0.92, SD=0.08) was significantly more than the cast index (mean 0.77, SD=0.07) in the others (p< .001). Discussion. A high cast index in post manipulation radiographs indicates increased risk of re-displacement of the fracture and these patients should be kept under close review. Conclusion. Cast index is a valuable tool to assess the quality of moulding of the cast following closed manipulation of distal radius fractures in children. The maximum acceptable cast index should be 0.82

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

This project highlights the red flags in postoperative rehabilitation of total ankle replacement (TAR) patients managed with two different postoperative rehab regimes. 20 TAR patients were recruited for a pilot RCT between 2008 and 2011; they were randomized to 2 groups (immobilisation in a below knee plaster cast for 6 weeks vs. early mobilisation following TAR); all patients underwent a graded outpatient Physiotherapy program until 12 weeks postoperatively. Assessments included questionnaires, complications, American Orthopaedic Foot and Ankle Score (AOFAS) done preoperatively, 3 and 6 months after surgery. Results. 20 TARs for OA (13) and PTOA (7) took part in the trial. There were 10 patients in each arm of the study. Mean age 61.2 years; mean BMI was 29.4. Of the plaster group, there was 1 incidence of fracture medial malleolus (MM) at 6 weeks after removal of plaster cast, 1 fracture MM at 5 months following walking on the beach, 1 fracture (MM) after completion of outpatient physiotherapy session, and 1 fracture MM of unknown reason at 1 year. Of the early mobilisation group, there was 1 intraoperative fracture of tibia (treated conservatively); 1 fracture MM 6 weeks post-op; 2 fracture MM at 8 weeks post-op. All patients had good clinical outcomes at successive follow up assessments. Conclusion. These results highlights the need for considering a lighter exercise regime, and re-evaluating patient lifestyle, return to recreational activities and feedback on home exercise programs during planning and execution of each phase of postoperative rehabilitation programs to aid prevention of early fractures in patients following TAR

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

Developments in plate technology have increased interest in the operative fixation of Colles' fracture. The vast majority of patients are treated non-operatively, yet there are few medium or long-term outcome studies. The aim of this study was to evaluate medium-term outcome of a cohort of patients who previously received treatment in a plaster cast. 236 patients entered two previous prospective, randomised control studies comparing closed reduction techniques or plaster cast type. Both studies showed no difference in clinical or radiological outcome between groups. 43% of this cohort had a final dorsal tilt of > 10° and 44% had final radial shortening of >2mm. All patients now have a minimum follow-up of five years and 60 have died. The remaining 176 patients were contacted by post and asked to complete two validated patient-based questionnaires: a modified Patient Evaluation Measure and a quickDASH. 112 replies were received. The mean age of patients is 67 years (range 23 – 91 years). 31 patients are employed and 57 retired. 77% of patients had a quickDASH score of less than 20. 59% of patients never experience wrist pain whilst 8% of patients have daily pain. All Patient Evaluation Measures have shown a median score of 12 or less (0=excellent, 100= terrible). The best score was for pain (median 4; IQR 2-12) and the worst for grip strength (median 12; IQR 4 – 41). No radiological outcome 5 weeks after injury correlated with any outcome score, except for dorsal tilt, which correlated with difficulty with fiddly tasks (p=0.04) and carpal malalignment which correlated with interference with work (p=0.04). In conclusion, our results show a good functional outcome five years after non-operative management of Colles' fracture. A degree of malunion is acceptable and in the light of our results the economic impact of surgery must be evaluated

One hundred and sixty-seven patients with adolescent idiopathic scoliosis were allocated prospectively to one of three different groups for correction before undergoing posterior spinal fusion and Harrington instrumentation, In group 1 single curves were corrected by a Risser turnbuckle plaster jacket and double curves by halo-pelvic traction. In Group 2 patients performed Cotrel dynamic traction for three weeks and this was followed by correction in a plaster cast. In Group 3 patients were given Cotrel dynamic traction for one week only and the operation was performed without a plaster cast. There was no significant difference in the overall correction achieved among the patients in the three groups except that double curves corrected slightly better in Group 2. The correction achieved by Cotrel dynamic traction after three weeks was not significantly different from that obtained at 48 hours. An anteroposterior radiograph of the spine taken during Cotrel dynamic traction was a valuable guide to the mobility of the curve and is preferable to radiographs of the patients bending laterally, particularly with respect to curves over 70 degrees. The paper concludes that correction before operation is not required routinely in adolescent idiopathic curves unless the deformity is a severe and rigid one in which case a radiograph during Cotrel traction is a useful assessment

We performed CT to investigate how treatment may modify the basic skeletal pathology of congenital club foot. Two homogenous groups of patients treated by one of the authors (EI) or under his supervision were studied. The first included 32 patients with 47 club feet reviewed at a mean age of 25 years and treated by manipulation, application of toe-to-groin plaster casts and an extensive posteromedial release. The second included 32 patients with 49 club feet reviewed at a mean age of 19 years and treated by the Ponseti manipulation technique, application of toe-to-groin plaster casts and a limited posterior release. At follow-up the shape of the subtalar, talonavicular and calcaneocuboid joints was found to be altered in many feet in both groups. This did not appear to be influenced significantly by the type of treatment performed. Correction of the heel varus and the increased declination angle of the neck of the talus was better in the club feet of the second group, whereas reduction of the medial subluxation of the navicular was better in the first. There was a marked increase in the external ankle torsion angle in the first group and a moderate increase of this angle in the second group, in which medial subluxation of the cuboid on the anterior apophysis of the calcaneum was always corrected. Equinus was corrected in both groups but three-dimensional CT reconstruction of the whole foot showed that cavus, supination and adduction deformities were corrected much better in the second group

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

A key factor delaying rehabilitation after a tendo Achillis (TA) rupture is gait abnormality. We quantified changes in planter pressures after a rupture of the TA in four groups of patients:. 15 controls subjects, mean 40 years, with no history of lower limb abnormality. 14 patients, mean 48 years, treated in a non-weight-bearing plaster cast. 12 patients, mean age 45 years, treated with immediate weight-bearing in a ‘rigid’ orthosis. 14 patients, mean age 51 years, treated with immediate weight-bearing in a ‘flexible’ orthosis. Mean and maximum peak planter pressures within the forefoot and heel were measured using in-shoe pressure pads two weeks after removal of the cast/orthosis; five gait cycles were recorded. The terminal stance and pre-swing phases were also measured as a proportion of the total stance phase of the gait cycle. One-way ANOVA was used to compare the difference in means between the groups. The normal control group had less than 2% difference between the limbs on all of the measured parameters. The patients in the plaster cast and ‘rigid’ orthotic groups had significant deficits (p = 0.04 and < 0.001 compared to control) in mean peak forefoot pressures, implying weakness in the triceps surae. However, the patients in the flexible orthosis group had only an 11% deficit (p = 0.25 compared to control). All of the patients treated for a TA rupture had increased heel pressures but only the ‘rigid’ orthotic group had cadence abnormalities (p = < 0.001). This may be the result of abnormal motor patterns secondary to mobilising in the rigid orthosis. This study highlights the gait abnormalities associated with triceps surae weakness following rupture of the TA. Accelerated rehabilitation using weight-bearing orthotics may alleviate some of these problems, but new designs for flexible orthotics may be required for maximum benefit

Introduction: Traditionally Short arm plaster casts have been used to treat distal radius fractures. Judging adequacy of immobilisation has never been defined. A significant proportion of these fractures loose reduction due to inadequate immobilisation. A new non-invasive external fixator technology has been introduced to address the shortcomings of plaster casts. Aim: Is the new non invasive fixator better at reducing skin device interface movement, than conventional plasters. Materials and Methods: A prospective healthy volunteer study involving application of Short arm plaster of Paris cast, fibreglass cast and a new device Cambfix non-invasive wrist fixator with 15 forearms in each group, was undertaken. IRB approval and informed consent obtained from the volunteers. Colle’s type cast configuration was used. Displacement at the skin-cast and skin-new device interface was measured at proximal and distal ends. Maximal displacements noted immediately after application and after a specified intervals. Casts were windowed at the end of experiment and Cast index and Gap index were measured as ratios at the time of removal of casts. Statistical analysis was done using T-test and SPSS. Results: The non-invasive Cambfix fixator showed less mean displacement at both the proximal and distal parts compared to plaster and fibreglass casts (p< 0.01). The mean gap index for the Cambfix device was 0.09, which was statistically significantly less than 0.15 and 0.14 for Plaster of Paris and fibreglass casts respectively (p< 0.01). Casts with higher gap index showed increased displacement, however cast index was less predictive of skin-cast displacement. Conclusions: Skin-device interface movement was significantly better reduced with the Cambfix non-invasive fixator as compared with Short arm plaster of Paris and fibreglass casts. Lesser gap index is known to provide less interface movement. The Cambfix non-invasive fixator appears to achieve a better gap index more consistently. Limitations include healthy volunteer group, and relatively small numbers

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 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. Also, the tolerance to handling was assessed by moving the hinge joint while the casts were setting. Three identical jigs with hinged metal rods were designed to simulate Colle’s 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 8 groups and 42 tests). RESULTS: Most deformation occurred within 1 hour for FG casts and 24 hours for POP casts. The total deformation in FG cast (mean 3.4 mm) was significantly less than in POP casts (mean 6.2 mm) (p > 0.05). 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: Several institutes in continental Europe and the US now prescribe low molecular weight heparin for patients with ankle fractures being treated in a below knee plaster cast. Jorgensen et al reported an incidence of deep venous thrombosis (DVT) of up to 20% in patients treated in a cast. However, their study included patients with variable diagnoses, ranging from tendon ruptures to fractures. The aim of our study was to assess the incidence of DVT in patients with ankle fractures that have been treated conservatively in a below knee cast. Method: We performed an ultrasound scan on patients with conservatively ankle fractures at the time of removal of the cast. The same ultrasound technician performed all the scans. The local regional ethics committee had approved this study. Results: So far we have performed an ultrasound scan on 98 patients with ankle fractures. We are likely to complete the study in November 2006 (120 patients). We have encountered only 2 below knee DVTs (2.04 %). None of them involved the popliteal vein. Both patients were completely asymptomatic and were full weight bearing in the cast. A repeat scan showed no evidence of progression. None of the patients had an above knee DVT or a pulmonary embolism. Discussion: The risk of deep venous thrombosis is said to be higher in patients with a plaster cast because of the decreased ability of the calf muscles to pump the venous blood back to the heart. Though some studies have indicated an incidence of up to 20%, the incidence in our population was only about 2%Thus, DVT is a rare event in patients with ankle fractures. Though it is a serious event, its rarity does not justify a blanket prophylaxis regimen for all patients with ankle fractures

Clubfoot deformity is the most common congenital musculoskeletal disorder (1). Approximately one in one thousand people are born with at least one clubfoot; between 150,000 and 200,000 babies are born with a clubfoot each year (2). Eighty percent of these cases occur in developing countries, and the majority is left untreated. When infants are treated with a non-invasive casting technique pioneered by Ignacio Ponseti M.D., they generally can be “cured” with relative ease. In the United States, 97% of patients given this treatment can walk successfully and are able to live normal lives (3). The Ponseti Method requires several plaster casts but either no or minimal surgery, can be taught fairly easily not only to doctors but also to healthcare workers, nurses, and other people who have some knowledge and training in healthcare. Also, it requires plaster casting, making it an inexpensive treatment. Dr. Ignacio Ponseti first performed his non-invasive treatment in 1949, but didn't publish his results until 1963. Two more papers, published in 1979 and 1995 described the long-term outcomes of treatment. In 1996 Oxford Press published a book detailing his approach. Although the treatment has always had high success rates, a lack of publicity prevented it from becoming more widely used until the late 1990s. Its basic mechanism consists of a series of plaster casts and manipulations that gradually reshape the foot around a fixed talus to obtain correction. Generally, between five and seven casts are required. The casts extend from the toes to the upper thigh and hold the knees at a right angle. One of the most important aspects of this method is timing: infants can be given treatment starting at seven days old and ideally should begin treatment before reaching eight months of age. Brazil, Uganda, Malawi and Chile now have official national programs, which are sponsored by each country's Ministries of Health, in which clinics in each country treat clubfoot disorder using the Ponseti Method. China set up a national program in 2005, but with a population of 1.3 billion people, it will take several years to complete the training. The prevalence of the Ponseti Method varies in the sixty other countries with healthcare workers trained in the treatment. This talk will review the principles of treatment and focus on results of recurrence after initial treatment with the Ponseti Method

Introduction: Olecranon fractures comprise 4–7% of all fractures around the elbow in the pediatric age group. 80% of these fractures can be treated expectantly. Fractures with 2 mm of displacement or more require surgical intervention. The surgical procedure commonly used is ORIF with 2 Kirschner wires and tension band wire as advocated by the AO technique. All open interventions require removal of hardware under anesthesia. We present our experience of five cases treated with percutaneously placed K-wires and absorbable sutures. Patients and Methods: Five patients, 4 boys and one girl, average age 6 8/12 years (range 4½-14¼ years) with displaced fractures of the olecranon were treated with ORIF during the years 2000–2004. In two cases additional injuries were noted [a displaced lateral condyle fracture in one and a dislocated radial head (Monteggia variant) in another patient]. Under general anesthesia, the olecranon is approached through a posterior incision. After reduction, fixation is achieved with two K-wires, which are inserted percutaneously. Additional fixation is obtained with a heavy absorbable suture (Dexon, PDS) which is fashioned in a figure of eight around the protruding pins and through a hole in the proximal ulna. Stability is checked under vision before wound closure. K-wires are trimmed and a plaster cast is fitted with the elbow in flexion. The plaster cast and K-wires are removed 4 weeks post surgery after X-rays confirm that the fracture is healed and range of motion is started. Results: Five patients have been treated with our technique; all fractures were reduced and stable in flexion and extension under vision at the end of surgery. K-wires were removed 4 weeks postoperatively and patients were allowed free range of motion. No immediate complications were noted, none became infected and no loss of fixation was observed. Conclusions: Anatomic reduction and stable fixation can be achieved by the surgical technique presented. The usual complication of hardware irritation and the need for additional surgery to remove K-wires and the metal TBW are avoided by the use of absorbable sutures and protruding K-wires. Functional outcome is excellent on short term follow-up. Larger numbers and prospective follow-up will tell whether this technique can replace the commonly used methods of olecranon fracture fixation in the pediatric age group

Aims. To our knowledge, there is currently no information available about the rate of venous thromboembolism (VTE) or recommendations regarding chemoprophylaxis for patients whose lower limb is immobilized in a plaster cast. We report a retrospective case series assessing the rate of symptomatic VTE in patients treated with a lower limb cast. Given the complex, heterogeneous nature of this group of patients, with many risk factors for VTE, we hypothesized that the rate of VTE would be higher than in the general population. Patients and Methods. Patients treated with a lower limb cast between 2006 and 2018 were identified using plaster room records. Their electronic records and radiological reports were reviewed for details about their cast, past medical history, and any VTE recorded in our hospital within a year of casting. Results. There were 136 episodes of casting in 100 patients. The mean age was 55 years (22 to 91). The mean time in a cast was 45 days (five days to eight months). A total of 76 patients had neuropathy secondary to diabetes. No patient received chemical thromboprophylaxis while in a cast. One VTE (0.7% of casting episodes) was documented. This was confirmed by Doppler scan nine days after removing the cast. Conclusion. The frequency of VTE was higher than that of the general population (0.05%); this is most likely attributable to our patients’ apparent increase in VTE risk as suggested by The National Institute for Health and Care Excellence (NICE). These findings suggest that thromboprophylaxis is not routinely indicated in patients who undergo immobilization of the lower limb in a cast, although the risks of VTE should be assessed. While the cast itself does not pose an increased risk, other pathologies, such as active cancer, mean that each individual case needs to be considered on their merit.

This study reviews the results of the treatment of non-union of fractures of the scaphoid by the use of micro-surgical, vascular pedicle grafts (VPG). The indications for VPG included long-standing non-union of a fracture of the scaphoid, avascular necrosis of the proximal pole and failed conventional grafting. The contraindications were periscaphoid degenerative changes (scaphoid non-union advanced collapse) and vascular damage from previous surgery. The technique in each involved harvesting a vascularised bone graft from the distal radius based on a vascular pedicle with retrograde flow from one of a number of described vessels that constitute the vascular plexus over the carpus. The scaphoid was prepared to receive an inlay graft and then the graft was positioned and its stability was determined. Some were secured with a single 0.7mm diameter Kirschner wire. The wrist was then immobilised in a plaster cast until either the fracture had healed or it was evident that the procedure had failed to result in union. Fourteen patients have undergone VPG over 30 months. Of these eight have healed (four fractures of the waist and four of the proximal poles), four have failed (one waist and three proximal poles) and two are still in plaster casts. The mean time to healing was 20.6 weeks (range: 12.7–28.7 weeks). Of the eight that healed, seven were aged between 21 and 27 years. The four failures were aged between 34 and 44 years. The mean time since the fracture in the healed group was 2.9 years (range: 1.2 years to five years) and in the failed group it was 6.5 years (range: two years to 20 years). The first failure was related to deep infection and a subsequent Matte-Russe procedure has also failed. In the second failure the graft healed to the distal pole but the very small proximal pole collapsed resulting in a wrist arthrodesis. The graft in the third failure healed to the distal pole but failed to unite with the small proximal pole. No further treatment has been planned. The fourth failure was a non-union of the waist of 20 years standing. The graft became dislodged from the scaphoid but no further surgery has been carried out. One of the successful unions had a poor result because of degeneration in the scaphoid-trapezoid-trapezium (STT) joint secondary to damage done at the time of previous surgery (Herbert screw). A successful STT arthrodesis was done subsequently. VPG is technically challenging. Careful patient selection is vital as is preoperative planning and vessel selection. VPG can be used successfully to salvage obstinate non-unions of fractures of the scaphoid

The nervous system is known to be involved in inflammation and repair. We aimed to determine the effect of physical activity on the healing of a muscle injury and to examine the pattern of innervation. Using a drop-ball technique, a contusion was produced in the gastrocnemius in 20 rats. In ten the limb was immobilised in a plaster cast and the remaining ten had mobilisation on a running wheel. The muscle and the corresponding dorsal-root ganglia were studied by histological and immunohistochemical methods. In the mobilisation group, there was a significant reduction in lymphocytes (p = 0.016), macrophages (p = 0.008) and myotubules (p = 0.008) between three and 21 days. The formation of myotubules and the density of nerve fibres was significantly higher (both p = 0.016) compared with those in the immobilisation group at three days, while the density of CGRP-positive fibres was significantly lower (p = 0.016) after 21 days. Mobilisation after contusional injury to the muscle resulted in early and increased formation of myotubules, early nerve regeneration and progressive reduction in inflammation, suggesting that it promoted a better healing response

Background. The current ‘gold standard’ method for enabling weightbearing during non-invasive lower limb immobilisation is to use a Patella Tendon-Bearing (PTB) or Sarmiento cast. The Beagle Böhler Walker™ is a non-invasive frame that fits onto a standard below knee plaster cast. It is designed to achieve a reduction in force across the foot and ankle. Our objective was to measure loading forces through the foot to examine how different types of casts affect load distribution. We aimed to determine whether the Beagle Böhler Walker™ is as effective or better, at reducing load distribution during full weightbearing. Methods. We applied force sensors to the 1st and 5th metatarsal heads and the plantar surface of the calcaneum of 14 healthy volunteers. Force measurements were taken without a cast applied and then with a Sarmiento Cast, a below knee cast, and a below knee cast with Böhler Walker™ fitted. Results. Compared to a standard below knee cast, the Böhler Walker™ reduced the mean peak force through the first metatarsal head by 58.9% (p < .0001); 73.1% through the fifth metatarsal head (p < .0001); and by 32.2% (p < .0001) through the calcaneum. The Sarmiento cast demonstrated a mean percentage reduction in peak force of 8.6% (P = .39) and 4.4% (P = .87) through the 1st and 5th metatarsal heads respectively, but increased the mean peak force by 5.9% (P = .54) through the calcaneum. Conclusions. Using a Böhler Walker™ frame applied to a below knee cast significantly reduces loadbearing through the foot compared to a Sarmiento cast or a standard below knee cast. Implications. This could mean early weightbearing is safer and better tolerated in patients with a wide variety of foot and ankle pathologies, which can in turn improve quality of life and reduce the incidence of immobility dependent morbidity

Aims

Isolated fractures of the ulnar diaphysis are uncommon, occurring at a rate of 0.02 to 0.04 per 1,000 cases. Despite their infrequency, these fractures commonly give rise to complications, such as nonunion, limited forearm pronation and supination, restricted elbow range of motion, radioulnar synostosis, and prolonged pain. Treatment options for this injury remain a topic of debate, with limited research available and no consensus on the optimal approach. Therefore, this trial aims to compare clinical, radiological, and functional outcomes of two treatment methods: open reduction and internal fixation (ORIF) versus nonoperative treatment in patients with isolated ulnar diaphyseal fractures.

We compared two conservative methods of treating Weber B1 (Lauge-Hansen supination-eversion 2) isolated fractures of the lateral malleolus in 65 patients. Treatment by immediate weight-bearing and mobilisation resulted in earlier rehabilitation than immobilisation for four weeks in a plaster cast. There was no significant difference in the amount of pain experienced or in the requirement for analgesics and early mobilisation was not associated with any complications. We therefore advocate early mobilisation for these stable ankle fractures

1. In a series of 129 tibial fractures treated by compression plates, a high incidence of complications causing delay in healing was found in alcoholics and persons with abnormal personality traits. 2. The healing time and time off work for these people were about doubled. 3. The indications for internal fixation in such patients should therefore be sharply defined and, if used, added protection should be given by institutional care and by well controlled plaster casts

Acute fractures of the scaphoid were randomly allocated for conservative treatment in a Colles’-type plaster cast with the wrist immobilised in either 20° flexion or 20° extension. The position of the wrist did not influence the rate of union of the fracture (89%) but when reviewed after six months the wrists which had been immobilised in flexion had a greater restriction of extension. We recommend that acute fractures of the scaphoid should be treated in a Colles’-type cast with the wrist in slight extension

The results of ten excision arthroplasties of the elbow for rheumatoid disease are described. The operation may afford good relief of pain and a useful increase both of hinge motion and of forearm rotation. Instability is not a serious problem unless the patient has to bear weight on crutches. To increase stability after arthroplasty it appears that Kirschner wire fixation is advisable as well as a plaster cast. For advanced rheumatoid disease unilateral excision arthroplasty has a definite value, especially for patients confined to a wheelchair

Purpose of the study:. Is circular external fixation a safe and effective method of managing closed distal third tibia fractures. These fractures are conventionally treated with plaster casts, intramedullary nails or plate fixation. These treatment modalities have complication rates in the literature of up to 16% malunion, 12% non-union, and 17% deep infections. Description and Methods:. Retrospective review of 18 patients with closed distal third tibia fractures, with or without extension into the ankle joint, treated with circular fixator systems and minimal percutaneous internal fixation of the intra-articular fragment if required. Patients were followed up for time to union, malunion incidence as well as incidence of pin tract and deep infection. Distal third fractures which were extra articular or with simple intra articular extension were included. (AO 43 A, B1, C1, C2 + AO 42 in distal third) Patients with pilon fractures (AO 43 B2, B3 and C3) were excluded. Summary of results:. The average time to union in these patients was 16 weeks (11–33 weeks). The non-union rate was 11.1% in comparison to 12% with conventional treatment. The malunion rate was 0% compared to 16% with conventional treatment. The incidence of pin tract infection was 16.6%, but no deep infections were noted, whilst conventional treatment shows deep infection in up to 17%. Conclusion:. Circular external fixation is a safe and efficient option in the treatment of distal tibia fractures. The incidence of complications is significantly reduced in comparison to conventional treatment

Purpose:. Paediatric forearm fractures are commonly seen and treated by closed reduction and plaster cast application in theatre. Historically, cast application has been subjectively evaluated for its adequacy in maintaining fracture reduction. More recently emphasis has been placed on objectively evaluating the adequacy of cast application using indicators such as the Canterbury index (CI). The CI has been used in predicting post-reduction, re-displacement risk of patients by expressing the casting and padding indices as a ratio. The CI has been criticized for not including cast 3 point pressure, fracture personality and lack of standardization of X-ray views as well as practical requirement of physical measurement using rulers. The aim of this study was to determine whether subjective evaluation of these indices, on intra-operative fluoroscopy and the day 1 to 7 postoperative X-ray, was accurate in predicting a patient's ultimate risk of re-displacement, following reduction and casting. Materials and Methods:. In total, 22 X-rays from 11 patients were evaluated by 20 orthopaedic registrars and 8 consultants, before and after a tutorial on the Canterbury index. Results:. Formal tutorial did not show an increased subjective predictive accuracy. No clear correlation could be demonstrated between CI and the clinical outcome. Conclusion:. Value of the CI in clinical practice is doubtful due to various confounding factors. The CI has been used due to lack of other available systems, and ideally a system should be sought which incorporates fracture personality, cast 3 point pressure and standardisation of X-Rays

We reviewed 83 patients after below-knee amputation. In 56 with 69 amputations early management was by plaster-pylon. A plaster cast is applied in the operating room, and a pylon added one week later, after which full weight-bearing is allowed. We compared these patients with 27 who had soft bandaging. The 'healing' time was reduced from 98 days to 40 days, and there were no major complications in the plaster-pylon group. The technique is simple and cheap and can be used by paramedical staff without specialised training or equipment

One hundred patients with acute ruptures of the lateral ligaments of the ankle were randomly allocated either to conservative treatment in a plaster cast or to operative repair. With the aid of stress tenography, the extent of the injury was established. There were 30 patients with isolated anterior talofibular ruptures and 20 with additional calcaneofibular ligament ruptures in each treatment group. Operative repair was associated with a higher incidence of complications in the first weeks, and slightly delayed the patients' return to work. At an independent two-year review there was no evidence that operative repair offered improved symptomatic or functional benefit

1. The management of fractures in five patients with haemophilia is described: two patients had antibodies to antihaemophilic globulin. 2. The principles of management of injured haemophilia patients are described, as are the special problems in patients with antibodies to AHG. 3. Stability of the fragments must be achieved to prevent the hazards of displacement of the fracture, recurrent bleeding and pseudotumour formation which may threaten viability of the limb. 4. Stabilisation of potentially unstable fractures can be achieved at the onset by internal fixation. Plaster casts should be reserved for stable fractures or fractures occurring in young children

Any intervention for limb with compromised bone and soft tissue in paediatric age group is often studded with complications of flare of infection, wound breakdown, delayed healing or failure of grafting. We report our experience with managing 8 such cases with periosteal sleeve taken from tibia along with fibular grafting. The lesion was gap non-union following bone sequestration in 7 cases (2 proximal humerus; 4 femur and one metacarpal) and one case tibia vara in post osteomyelitic tibia. The infective lesions were silent for minimum of 1 year before this procedure. The periosteal sleeve was taken from proximal tibia and fibular graft was also procured from same leg. Following freshening of bone ends, the fibular graft was applied at non-union/osteotomy site and enclosed in the freshly harvested periosteal sleeve. The limb was protected in plaster cast for 6 weeks and assessed clinicoradiologically at 3 and 6 weeks intervals. Uneventful union followed in 7 cases in 6 weeks time. In one case of proximal humerus, the osteosynthesis attempt failed. The periosteal and fibular graft site posed minimal morbidity for the child. Conclusions. Periosteal sleeve and fibular grafting offers a promising alternative for interventions in post osteomyelitic bone with compromised soft tissue

The aim of this study was to compare immediate weight-bearing mobilisation with traditional plaster casting in the rehabilitation of non-operatively treated Achilles tendon ruptures. Forty-eight patients with Achilles tendon rupture were randomised into two groups. The treatment group was fitted with an off-the-shelf carbon-fibre orthotic and the patients were mobilised with immediate full weight-bearing. The control group was immobilised in traditional serial equinus plaster casts. The heel raise within the orthotic and the equinus position of the cast was reduced over a period of eight weeks and then the orthotic or cast was removed. Each patient followed the same rehabilitation protocol. The primary outcome measure was return to the patient's normal activity level as defined by the patient. There was no statistical difference between the groups in terms of return to normal work [p=0.37] and sporting activity [p=0.63]. Nor was there any difference in terms of return to normal walking and stair climbing. There was weak evidence for improved early function in the treatment group. There was 1 re-rupture of the tendon in each group and a further failure of healing in the control group. One patient in the control group died from a fatal pulmonary embolism secondary to a DVT in the ipsilateral leg. Immediate weight-bearing mobilisation provides practical and functional advantages to patients treated non-operatively after Achilles tendon rupture. However, this study provides only weak evidence of faster rehabilitation

Aims

The aim of this study was to compare the cost-effectiveness of surgical fixation with Kirschner (K-)wire ersus moulded casting after manipulation of a fracture of the distal radius in an operating theatre setting.

Hindfoot (subtalar) movement and disability after fracture of the tibial shaft have been studied. One hundred patients with soundly healed fractures of the tibial shaft treated by immobilisation in a long leg plaster cast were examined at least one year after the fracture had healed. Subtalar movement was accurately measured by a special technique and the patients were questioned specifically about any disability associated with their hindfoot. Subtalar movement was limited to some degree in 72% of patients. Forty-three per cent of patients complained of symptoms related to their subtalar joint and 12% found these symptoms troublesome

A six-year-old girl with congenital sensory neuropathy with anhidrosis (CSNA) presented with bilateral hip dysplasia and subluxation on the right side. Conservative treatment of the hips by closed reduction and a plaster cast was unsuccessful. When aged seven years the patient had an intertrochanteric varus rotation osteotomy on the right side, but subluxation was again evident after five months. A Salter-type pelvic osteotomy was carried out followed by immobilisation, but one year later subluxation was present in the right hip and dislocation in the left. At the age of nine years, the right femoral head resembled a Charcot joint, although walking ability was preserved. In patients with CSNA, surgery may not always be advisable

We measured pressures in the anterior and deep posterior compartments continuously for up to 72 hours in 20 patients with closed fractures of the tibial shaft treated primarily in plaster casts. All were examined independently after periods of three to 14 months. Pressures above 40 mmHg occurred in seven (35%) and above 30 mmHg in 14 (70%). No patient had the symptoms of compartment syndrome during monitoring. Abnormalities at review did not correlate with the maximum consecutive time periods during which the compartment pressures were raised. Thus, in the absence of symptoms the monitored pressures did not relate to outcome. Routine monitoring in this type of patient is therefore of doubtful benefit

Aims: The aim of this study was to þnd out if undisplaced displaced distal radial fractures require plaster immobilisation. Methods: In this prospective study, undisplaced distal radial fractures were divided into two groups; plaster immobilisation was used for one group while removable volar splint was used for the other group. Follow up was at six weeks, three months and six months. Patients were assessed by clinical examination, grip strength, radiological assessment, EQ-5D and a Short Form 12 questionnaire. Results: At 3 months, no difference was found between the two groups in clinical evaluation, radiological assessment, the functional outcome, grip strength, and visual analogue score for pain. Conclusions: We conclude that undisplaced distal radius fractures can probably be treated with out a plaster cast and put straight into wrist orthosis

We report a prospective study of the causes and treatment of 26 long-standing neuropathic ulcers of the foot in 21 patients. The most important causal factor, well illustrated by pressure studies, was the presence of a dynamic or static deformity leading to local areas of peak pressure on insensitive skin. All but one of the 26 ulcers had healed after an average of 10 weeks of treatment in a light, skin-tight plaster cast, with the prohibition of weight-bearing. Recurrent ulceration was prevented in all but one foot by early operation to correct the causative deformity; this was performed after the ulcer had healed and before allowing weight-bearing on the limb. Pressure studies after operation confirmed that pressure points had been relieved

Forty-seven patients over the age of 55 years with a displaced fracture of the ankle were entered into a prospective, randomised study in order to compare open reduction and internal fixation with closed treatment in a plaster cast; 36 were reviewed after a mean of 27 months. The outcome was assessed clinically, radiologically and functionally using the Olerud score. The results showed that anatomical reduction was significantly less reliable (p = 0.03) and loss of reduction significantly more common (p = 0.001) in the group with closed treatment. Those managed by open reduction and internal fixation had a significantly higher functional outcome score (p = 0.03) and a significantly better range of movement of the ankle (p = 0.044) at review

Introduction:. The National institute of Health and Clinical Excellence (NICE) guidelines for thromboprophylaxis following lower limb surgery and plastercast immobilisation recommend pharmacological prophylaxis be considered until the cast is removed. These guidelines have been extrapolated from data for hip and knee arthroplasty, and trauma studies. Recent studies have questioned the validity of these guidelines. At Portsmouth, low molecular weight heparin (LMWH) is prescribed for 14 days following surgery in high risk patients. The protocol predates the most recent NICE guidance. We set out to investigate whether this was a safe method of thromboprophylaxis following elective hindfoot surgery. Methods:. A retrospective audit of all patients undergoing hindfoot surgery between 01/01/10 and 31/12/12 was performed. All patients were immobilised in a POP backslab and prescribed 14 days of LMWH. All patients were reviewed at 2 weeks and converted to a full cast or boot. Immobilisation was continued for between 6 and 12 weeks. A list of all patients who had undergone investigation for deep vein thrombosis at Queen Alexandra hospital from 01/01/10 to 28/03/13 was obtained from the VTE investigation department. The two lists were cross referenced to identify any DVTs occurring following hindfoot surgery and plastercast immobilisation. Results:. During the 3 years, 197 major hindfoot operations were performed in 194 patients. Mean age was 53 years (range18-82) and 94 males with 100 females. Two patients had confirmed deep vein thromboses; 1 patient at 13 days post op while receiving LMWH prophylaxis. Conclusion:. Symptomatic VTE following elective hindfoot surgery and post operative plaster cast immobilisation in our hospital is rare. There are no randomised controlled trials to guide thromboprophylaxis regimes following hindfoot surgery. Based on our results, our protocol appears to be effective and safe

We carried out a randomised, prospective, multicentre clinical trial of the treatment of Colles’ fractures. A total of 339 patients was placed into two groups, those with minimally displaced fractures not requiring manipulation (151 patients) and those with displaced fractures which needed manipulation (188 patients). Treatment was by either a conventional Colles’ plaster cast (a control group) or with a prefabricated functional brace (the Aberdeen Colles’ fracture brace). Similar results were obtained in both groups with regard to the reduction and to pain scores but the brace provided better grip strength in the early stages of treatment. This was statistically significant after five weeks for both manipulated and non-manipulated fractures. At the tenth day the results were statistically significant only in manipulated fractures. There was no significant difference in the functional outcome between the two treatment groups. However, younger patients and those with less initial displacement had better functional results

1. A modification of the McLaughlin technique of lag screw fixation of the fractured scaphoid is described. 2. Fifty-six patients operated upon between 1956 and 1966 have been reviewed and their fractures classified under the headings recent, delayed union and non-union. 3. Plaster casts were avoided and early return to work encouraged; 95 per cent did so within two months. 4. Of twenty-two recent fractures, including three perilunar trans-scaphoid dislocations, nineteen united; of fifteen showing delayed union, eight united: and of nineteen cases of non-union, only two united. 5. The function of the wrist in the seventeen cases of persistent non-union stabilised by lag-screw was surprisingly good; only one patient has required arthrodesis to date. 6. The indications and contra-indications for the operation are discussed

Aims

In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED. We investigated whether this altered care pathway leads to a reduction in healthcare consumption and concomitant costs.

Introduction. Venous thromboembolism (VTE) represents a major cause of morbidity, mortality and financial burden to the NHS. Acquired risk factors are well documented, including immobilisation, lower limb plaster cast and surgery. NICE guidance on VTE prophylaxis within orthopaedics currently excludes operative ankle fracture fixation (ankle ORIF). Aims. Ascertain the local incidence of VTE; compare our local VTE rates with published data from other institutions; review guidelines, scientific literature and other hospitals policies; formulate a local policy for VTE prophylaxis. Method. Retrospective analysis of records of all patients undergoing ankle ORIF in our hospital over a continuous 5 year period, identifying cases of VTE, individual risk factors and surgical duration. Results. 380 patients underwent ankle ORIF; 3 developed VTE; no mortality. VTE incidence 0.79% (0.26%DVT; 0.53%PE). Operative duration 88 +/− 34mins (mean +/− 1S.D); in those with VTE, duration was 35, 90&85min. There is no statistically significant difference (p=0.18) observed between our local and national VTE incidence rates. Operative duration was not a significant factor in those developing VTE. Additional risk factors were identified in one patient with VTE. Discussion. The incidence of heparin induced thrombocytopenia is 0.5%, its associated mortality 10% (i.e. 1:2000). To prevent one fatal PE in foot & ankle surgery, 10,000 must receive VTE prophylaxis. Therefore, heparin associated mortality exceeds VTE associated mortality in foot & ankle surgery. Conclusion. Our local VTE rates are comparable to national rates. Risk of pharmacological prophylaxis exceeds benefit; therefore routine use not justified. Individual risk should be assessed; higher risk patients may benefit

Purpose. The treatment of children with contractures involving the lower limbs is challenging. Many are confined to wheelchairs for several years till their potential to ambulate is discovered. The aim is to review the treatment and outcome of eight children treated for contractures and deformities of the lower limbs following confinement to wheelchairs. Methods. Eight children aged 4–14 years were treated for contractures of the hips, knees and feet between 2005 and 2011. The initial diagnosis was not made in 5 children. All children had never walked previously. Four patients were labelled “cerebral palsy”. All children were seen with a physiotherapist to assess their walking potential. Genetic and paediatric medical assessment was also made. Final diagnosis revealed arthrogryposis (n = 3) pterygium syndrome (n = 1) calcinosis cutis (n = 1) viral neuropathy (n = 1) and cerebral palsy (n = 2). Clinically all children were assessed to have good upper limb function for use of crutches. Surgical correction of the feet was required in 6 patients. Extension osteotomies of the knees were done in 8 patients following serial plaster cast treatment and hamstring release. Hip releases were done in 4 patients. Results. The osteotomies healed well following above knee cast immobilisation. All patients are ambulant with above knee calipers, anterior knee straps and boots. Two children required repeat extension osteotomies. Follow up ranges between 8 months to 5 years. Conclusion. Patients with contractures of the lower limb should have careful clinical assessment. If upper limb function is suitable for holding crutches and the patients have the potential to kneel with the body erect, careful preoperative planning should be undertaken to improve the foot for weight bearing and the knees with extension osteotomies and ambulation. Accurate diagnosis is essential

Introduction. Fractures of the distal radius are one of the most common extremity fractures encountered in A&E departments and general adult fracture clinics. Over the last 10 years the rate of operation for distal radial fractures has been steadily increasing. Staff within our unit felt that formal teaching, particularly of new medical staff, with regards to fracture reduction and appropriate cast application could result in a reduction in operation rates. Methods. Retrospective data was extracted from FORD (Fracture Outcome and Research Database). Data included: the number of fractures in a 6 month period, number of fractures undergoing ORIF in that period, fracture configuration, patient demographics, and mechanism of injury. All patients undergoing ORIF had their radiographs assessed by 2 separate reviewers. Information regarding adequate fracture reduction, adequate cast application (using Gap Index calculation), and appropriate plaster cast moulding was recorded. Formal teaching was then given to the next group of medical staff rotating through the unit, and the same data was collected prospectively for that 6 month period. Exclusion criteria included bilateral injuries, and polytrauma patients. Results. A total of 1712 distal radial fractures were treated in our unit over the 12 month period, with 71 undergoing ORIF in the first 6 months and 37 in the second 6 months. Our study found that formal teaching and education of medical staff significantly reduced the operation rate for distal radial fractures in our unit. This effect was most significant for extra-articular, dorsally angulated fractures of the distal radius. Conclusion. In today's busy hospital environment it is sometimes all too easy to overlook the training of junior medical staff, our study proves that just 1 hour of basic training at the beginning of an attachment can have significant benefits to both the unit and, more importantly, the patients

A case is reported of an 18-year-old man with a post-traumatic radial shortening of about 10 cm with 40° of radial deviation as a consequence of an epiphyseal arrest that occurred when the patient was 8 years old. In the past the patient and his parents had refused all corrective treatment which would result in a permanent shortening; then a treatment by the Ilizarov external fixator was proposed. The forearm assembly was made by two fixed rings (one proximal and one medial) and one hinged distal ring. A closed corticotomy was performed parallel to the distal ring, whose fulcrum was at the ulnar styloid. Correction and lengthening were obtained by elongating two opposite threaded bars about 0.5 mm per day. Minor revisions were made on an out-patient basis. Time of correction and lengthening was 113 days, followed by 70 days in the fixator and a further 44 days of plaster cast after fixator removal. The complete correction of deformity and concurrent lengthening showed that Ilizarov‘s method is a definite but very demanding option in the treatment of severe deformities of the upper limb

A new and simple operative technique has been developed to provide rigid internal fixation for all types of fractures of the scaphoid. This involves the use of a double-threaded bone screw which provides such good fixation that, after operation, a plaster cast is rarely required and most patients are able to return to work within a few weeks. A classification of scaphoid fractures is proposed. The indications for operation included not only acute unstable fractures, but also fractures with delayed healing and those with established non-union; screw fixation was combined with bone grafting to treat non-union. In a prospective trial, 158 operations using this technique were carried out between 1977 and 1981. The rate of union was 100 per cent for acute fractures and 83 per cent overall. This method of treatment appears to offer significant advantages over conventional techniques in the management of the fractured scaphoid

Introduction: There is still debate on the effect of operative treatment on severe displaced intra-articular fractures of the os calcis. Operatively treatment consists of open reduction or percutanious screw fixation, with conflicting results. Although the results of either operative treatment are published, little is known about the long term results of non-surgical treatment of these difficult fractures. Patients and Methods: We analyzed the data of 35 patients with an intra-articular fracture of the oc calcis which were treated with a plaster cast between 1994 and 2006. All radiographs of the fracture and the radiograph at the latest follow-up were analyzed. All patients which could be traced were invited for a clinical examination and a radiograph. A Foot Function Index-score (FFI) and AOFAS score were recorded as clinical outcome. A regression analysis was performed with the clinical outcome (AOFAS score and FFI) as outcome and age, gender, Bohler’s and Gissane’s angles, trauma mechanism and type of fracture as predictors. Results: After a median follow-up of 10 years the mean AOFAS score was 75.8 (range29–100) and the FFI was 22.9 (range 0–71). In the regression analysis we found that none of the predictors could predict the outcome. Even the Bohler’s and Gisae angle did not predict the clinical outcome. Although there was a strong correlation between the Bohler’s angle on the lateral radiograph and the occurrence of degenerative changes in the long term follow-up, both Bohler’s angle and the degenerative changes did not correlate with the clinical measures. Conclusion: Although Bohler’s angle is a strong predictor for degenerative changes after a calcaneal fracture, both Bohler’s angle and the degenerative changes on the radiograph were not correlated with the clinical outcome

Aims: Pathologic studies in foetuses and stillborns with congenital clubfoot have shown atrophy of the musculature of the leg omolateral and incresased fibrous tissues within the muscles belly. Both the triceps surae and the tibialis posterior are mostly involved and their tendons thickened. Atrophy of the musculature of the leg has been described in various clinical studies on congenital clubfoot, but most of the authors believe that atrophy might be secondary to surgical treatment and prolonged immobilization in plaster cast and brace. In our study, we correlated the pathology of foetal leg muscle atrophy with leg muscle atrophy shown by patients with congenital clubfoot. Methods: We investigated the MRI aspects of leg muscles in untreated babies and in children and adults who had been treated soon after birth for unilateral congenital clubfooft. The MRI aspects of the leg muscle in treated patients were compared to those of untreated babies, and to the histopathologic findings of the same muscles in foetuses with congenital clubfoot. Results: The ratio between the muscles of the normal leg and the leg of the clubfoot side was almost the same as measured either on the histological sections of foetuses with congenital clubfoof or in patients before and after treatment, from birth to adulthood. Conclusions: Our study shows that in congenital club-foot leg muscle atrophy is a primitive pathologic finding rather than secondary to treatment

Forty patients with acute complete rupture of the calcaneal tendon were managed conservatively and randomly allocated to treatment groups using either cast immobilisation for eight weeks, or cast immobilisation for three weeks, followed by controlled early mobilisation in a Sheffield splint. The splint is an ankle-foot orthosis which holds the ankle in 15 degrees of plantar flexion, but allows some movement at the metatarsophalangeal joints. It is removed to allow controlled movement during physiotherapy. Patients treated with the splint regained mobility significantly more quickly (p less than 0.001) and preferred the splint to the plaster cast. The range of dorsiflexion at the ankle improved more rapidly after treatment in the splint (p less than 0.001), and patients were able to return to normal activities sooner. Recovery of the power of plantar flexion was similar in the two treatment groups, and no patient had excessive lengthening of the tendon. One re-rupture occurred in each group

The capacity for physiotherapy to improve the outcome after fracture of the distal radius is unproven. We carried out a randomised controlled trial on 96 patients, comparing conventional physiotherapy with a regime of home exercises. The function of the upper limb was assessed at the time of removal of the plaster cast and at three and six months after injury. Factors which may predict poor outcome in these patients were sought. Grip strength and hand function did not significantly differ between the two groups. Flexion and extension of the wrist were the only movements to improve with physiotherapy at six months (p = 0.001). Predictors of poor functional outcome were malunion and impaired function before the fracture. These patients presented with pain, decreased rotation of the forearm and low functional scores at six weeks. Our study has shown that home exercises are adequate rehabilitation after uncomplicated fracture of the distal radius, and routine referral for a course of physiotherapy should be discouraged. The role of physiotherapy in patients at high risk of a poor outcome requires further investigation

Introduction/Aim. Thromboembolism is a significant cause of patient morbidity and mortality, the risk of which increases in orthopaedic patients with lower limb immobilisation. It was therefore, our aim to identify a difference in symptomatic thromboembolism by treating acute Achilles tendon rupture patients with conventional non- weight bearing plaster versus functional weight bearing mobilisation. Methodology. The notes of 91 consecutive patients with acute Achilles tendon rupture were reviewed. The patients' demographics, treatment modality (non- weight bearing plaster versus weight bearing boot), and predisposing risk factors were analysed. From the 91 patients, 50 patients with acute Achilles tendon rupture were treated conservatively in a non- weight bearing immobilisation cast. From these 50 patients, 3 then underwent surgery and were therefore excluded from the results. 41 patients were treated with functional weight bearing mobilisation. Patients who did have a symptomatic thromboembolic event had an ultrasound scan to confirm a deep vein thrombosis of the lower limb, or a CT-scan to confirm pulmonary embolism. Results. Out of the 47 patients who were treated conservatively in a non-weight bearing plaster cast, 9 patients (19.1 %) had a thromboembolic event. Out of the 41 patients who were treated with functional weight bearing mobilisation, 2 patients (4.8%) had a thromboembolic event. Thus, patients who were treated in a non-weight bearing plaster had a significantly higher risk of developing thromboembolism (p value of <0.05) and an increased risk ratio of 24% compared to those who were treated with functional weight bearing mobilisation. Conclusion. There is a significant decrease in the clinical incidence of thromboembolic events in patients treated conservatively with early mobilisation in the functional weight bearing boot compared to those treated in a non- weight bearing cast

Background: The treatment of congenital vertical talus has traditionally consisted of manipulation and application of casts followed by extensive soft-tissue releases. However, this treatment is often followed by severe stiffness of the foot and other complications. The purpose of this study was to evaluate a new method of manipulation and cast immobilization, based on principles used by Dobbs et al in patients with idiopathic congenital vertical talus, but applied in teratologic congenital vertical talus. Methods: Five consecutive cases of teratologic congenital vertical talus deformity were prospectively followed at a minimum of nine months post treatment with serial casting and limited surgery consisting of percutaneous Achilles tenotomy, fractional lengthening of the anterior tibial tendon, and percutaneous pin fixation of the talonavicular joint. The principles of manipulation and application of the plaster casts were similar to those used by Ponseti to correct a clubfoot deformity, but the forces were applied in the opposite direction. Clinical and radiographic assessments were carried out at the initial, immediate postoperative and the latest follow-up. Results: Initial correction was obtained both clinically and radiographically in all five feet. A mean of eight casts was required for correction. At the final evaluation, the mean ankle dorsiflexion was 20° and the mean plantar flexion was 31°. Radiographically, dorsal subluxation of the navicular recurred in one patient, but was functionally insignificant as the patient was a non-ambulator and required treatment for seating purposes only. At the time of the latest follow-up, there was a significant improvement in all of the measured radiographic parameters compared with the pretreatment values. Conclusions: Serial manipulation and cast immobilization followed by talonavicular pin fixation and percutaneous tenotomy of the Achilles tendon provides excellent results, in terms of the clinical appearance of the foot, and deformity correction, in patients with teratologic congenital vertical talus

We describe a new technique for examining the infant hip using ultrasound. Both hips are imaged simultaneously via an anterior approach. The examination can be done with the hip either extended or flexed and abducted. The method has three advantages: 1) since both hips are imaged simultaneously, lines can be drawn to assist in determining the relationship between the femoral head and the pelvis; 2) proximal, anteroposterior and lateral displacement of the femoral head can all be demonstrated; 3) the method is applicable to the infant in a harness or a plaster cast to demonstrate maintenance of reduction of a dislocated hip. The usual direction of dislocation of the femoral head was anterior and lateral. Proximal migration was also observed in cases with more severe dislocation. In flexion, the dislocated head of the femur often moved posterior to the acetabulum. Of 1276 hips, in 638 infants aged from three weeks to one year, 49 showed congenital dislocation. The accuracy of our anterior method of sonography in diagnosing congenital dislocation of the hip compared well with the method of Graf and with radiography

This is a study of children who first attended as infants with either progressive infantile idiopathic scoliosis or congenital scoliosis. All had a pattern of scoliosis in which early and damaging deterioration is inevitable. The infants were treated from before the age of three, initially by plaster casts and then a Milwaukee brace, followed at about the age of ten by correction and fusion. The cases were then observed to the end of growth or near that point. In the main study there were twelve cases, six of progressive infantile idiopathic scoliosis and six of congenital scoliosis, which were followed through this long period. Only one of the twelve had a curve worse at the end of growth compared with the initial radiograph as an infant; this one curve had increased only 16 degrees in almost as many years. Although small, the series does show that it is nearly always possible to control even the most serious scoliosis in an infant, if it is tackled early and unremittingly. There are supportive studies of children who have partially completed this regime, and interim results in a newer group of children with spina bifida and scoliosis

Successful treatment of bone fractures requires a balance between stability, to restore functional anatomy and allow early mobilisation (and thus avoid dystrophy). The healing occurs through complex interactions of inducing, enabling and inhibitory factors. The mechanical environment (e.g. stress and strain) in/around the fracture site regulates tissue changes throughout the healing process, including the formation of a fibro-cartilaginous callus and its progressive replacement by bone. The mechanical and biological environment is controlled substantially by the selection of the fracture stabilisation method achieving either absolute stability (mostly achieved with compression plating technique) or relative stability allowing a limited amount of dynamic fracture displacement across the fracture gap. A number of treatments may be used to accomplish these conditions, ranging from splinting with a plaster cast, external fixator or an intramedullary nail to rigid internal fixation using plates affixed to the bone fragments. Fixation methods are presently selected on the basis of general guidelines, but nevertheless the optimal stability/instability remains unclear and relies heavily on the surgeon’s experience. With the recently more and more widely used locking plates the question of the optimal fixation technique and applied stability to the fracture zone especially in simple fractures have raised again. To fill this knowledge gap, an interdisciplinary approach with in vitro and in vivo experiments seems to be essential. Analysing clinical situations and the healing course with mathematical modelling and computational simulations can further aid to understand the healing conditions in respect to stability. This presentation will give an overview on the role of the mechanical environment in fracture healing, and demonstrating clinical examples that highlight the relevance of this research

Aims: To show that the treatment of buckle fractures in children in a soft bandage, rather than a plaster cast, is an effective and safe method of treatment. Methods: In order to determine the difference between the two groups it was decided to compare the range of movement at three weeks. Power calculations were performed. This gave a required sample size of 23 for each group. The project was submitted for ethical approval in July 1999. Patients enter the trial after parents agree and sign the consent form. Allocation to either plaster or bandage is random and parents draw previously sealed envelopes themselves. Patients are seen each week and measurements taken of their range of movement. Results: Thirty seven patients have completed the study. 17 have been allocated to bandage the rest to cast. Those in bandage show an excellent range of movement at the þrst week with no reported problems on their questionnaires. One patient has transferred from bandage to plaster at the request of the parents. Conclusion: Results suggest a positive result for treatment in bandage with no reported adverse effects and, a highly desirable result for the patient. We would hope to suggest a change in treatment policy for such fractures

We report the outcome at a mean of 93 months (73 to 110) of 71 patients with an acute fracture of the scaphoid who were randomised to Herbert screw fixation (35) or below-elbow plaster cast immobilisation (36). These 71 patients represent the majority of a randomised series of 88 patients whose short-term outcome has previously been reported. Those patients available for later review were similar in age, gender and hand dominance. There was no statistical difference in symptoms and disability as assessed by the mean Patient Evaluation Measure (p = 0.4), or mean Patient-Rated Wrist Evaluation (p = 0.9), the mean range of movement of the wrist (p = 0.4), mean grip strength (p = 0.8), or mean pinch strength (p = 0.4). Radiographs were available from the final review for 59 patients. Osteoarthritic changes were seen in the scaphotrapezial and radioscaphoid joints in eight (13.5%) and six patients (10.2%), respectively. Three patients had asymptomatic lucency surrounding the screw. One non-operatively treated patient developed nonunion with avascular necrosis. In five patients who were treated non-operatively (16%) there was an abnormal scapholunate angle ( > 60°), but in four of these patients this finding was asymptomatic. No medium-term difference in function or radiological outcome was identified between the two treatment groups

Introduction: Arthrodesis of 1st MTPJ is performed using various fixation techniques including lag screws, dorsal plate and screws, K-wiring. We evaluated the strength of fixation using two staples placed at right angles. Methods: Ten pairs of cadaveric feet were dissected to harvest the hallux MTPJ. Planar cut of articular surfaces using a micro-saggital saw. The bony ends were then approximated with an intervening blade and fixed using 2 staples placed at right angles. The specimen was supported on either ends and subjected to 3 point loading using a materials testing machine (Instron). The load at which the joint opened up sufficiently to let the blade fall was recorded. The load at which the construct failed was then recorded. Results: The joint opened up at an average of 41 Newtons. The load to failure was 130 Newtons. The corresponding average values in kilograms were 4.19 kilograms for the opening of the joint and 12.61 kilograms for the failure of the construct. On full weight bearing using the heel weight bearing shoes that we normally use post-operatively, the forces going through the forefoot were 0 newtons/kilograms, calculated using a TEK SCAN (measures the foot pressure on walking). Conclusion: It is safe to walk patients using a heel weight bearing shoe (Benefoot post op wedge shoe) following 1st MTPJ fusion using staples (uniclip-NewDeal). This is a major advantage compared to other methods of fixation that require plaster cast immobilisation thus reducing inconvenience, plaster expenses and possible complications like DVT

Introduction: A review of the treatment of 33 open fractures in 29 children over the period 1997 to 2002. Method: Intravenous antibiotics, debridement and wound irrigation was performed prior to skeletal stabilisation incorporating plaster cast immobilisation (4%), K wire fixation (13%), screw fixation (13%), flexible intramedullary nail fixation (13%) and external fixation (57%). Secondary wound closure was undertaken if appropriate at 48 hours. The tibia was involved in 49% of cases with approximately equal distribution of other long bone extremities. Fractures were classified according to Gustilo et al (22% grade I, 26% grade II, 17% grade III and 35% grade IIIb). Results: The average age was 10 years in 22 boys and 7 girls. Tibial fracture union was an average of 9 weeks in gradeI and II compared with 20 weeks for grade III. The remaining fractures healed at an average of 10 weeks. Non union occurred in one patient (tibia). There was on case of growth arrest of the distal tibia. There were no cases of osteomyelitis. Discussion: Open fractures in children most often result from high energy trauma. An increase in fracture and soft tissue severity is associated with a delayed union. Physeal injuries require close observation for potential growth arrest

Introduction. To achieve tibiotalocalcaneal arthodesis, implants described range from external fixator, compression screws and anterior plate and the more recent retrograde calcaneal locked intramedullary nail. Our aim is to assess the outcome of the AO cannulated blade plate for tibiotalocalcaneal arthrodesis. Patients and methods. Four tibiotalocalcaneal arthrodeses were performed in three patients. The operative technique involves lateral approach to the distal fibula that was osteotomised and used as bone graft. The articular cartilage of ankle and subtalar joint was removed using an osteotome and congruent surfaces achieved. AO cannulated blade plate was applied on the lateral aspect to achieve compression. The postoperative protocol included a plaster cast for three months, followed by mobilization out of plaster. Results and discussion. At the mean follow up of 10 months (range five to fourteen months) all patients were pain free on full weight bearing. The union was achieved at three months which was confirmed clinically and radiologically. There was no infection, wound breakdown, or loss of position at the ankle or subtalar joints. Mean preoperative American Orthopaedic Foot and Ankle Society ankle/hindfoot score was 21 and postoperative score 83. We conclude that the cannulated blade plate is an alternate technique for tibiotalocalcaneal arthodesis, with no moulding of the implant required to attain satisfactory alignment

We present an objective method for predicting the redisplacement of paediatric forearm and wrist fractures. Novel radiographic measurements were defined and their value assessed for clinical decision making. In Phase I of the study we defined the cast index and padding index and correlated these measurements with the incidence of fracture redisplacement. Phase II assessed these indices for their value in clinical decision making. Cast Index (a/b) is the ratio of cast width in lateral view (a) and the width of the cast in AP view (b). Padding Index (x/y) isthe ratio of padding thickness in the plane of maximum deformity correction (x) and the greatest interosseous distance (y) in AP view. The sum of cast index and padding index was defined as the Canterbury Index. In Phase I, 142 children's radiographs were analysed and a statistically significant difference was identified between redisplacement and initial complete off-ending of the bones, cast index > 0.8 and padding index of > 0.3. There was no significant association with age, fracture location, seniority of surgeon or angulation. In Phase II, radiographs of 5 randomly selected cases were presented to 40 surgeons (20 consultants & 20 registrars). Following an eyeball assessment they were asked to measure the cast index and padding index (after instruction). With eyeballing the consultants predicted 33% and registrars 25% of the cases that redisplaced. After learning to measure the indices the accuracy increased to 72% for consultants and 81% for registrars (p<0.001). We conclude that the cast index, padding index and Canterbury Index are validated tools to assess plaster cast quality and can be used to predict redisplacement of paediatric forearm fractures after manipulation. They can easily be taught to orthopaedic surgeons and are more accurate than eyeballing radiographs in the clinical setting. Redisplacement can be predicted if cast index > 0.8, padding index > 0.3 and Canterbury Index > 1.1

Objective. In many institutions, serial casting and splinting requires many weeks of treatment and frequently results in surgery. This study evaluated the results of neonatal clubfoot correction with the Furlong method. This method was created by Furlong M.B. and Lawn G.W. in New York and was published in Archives of Pediatrics in 1960. Materials and Methods. This study reviews 95 neonates with 128 severe clubfeet (initial Pirani score 4,0 or more). Patients with arthrogrypotic clubfeet and other syndromes were not included. Age at presentation ranged from 4 hours to 18 days. All patients had no previous treatment. The cast application with extra space above the foot was performed as follows: a special elastic pad was placed on the dorsal aspect of the foot and fixed with a cotton bandage. Then plaster cast was applied with knee flexion 110–120 degrees. After the cast was set, the elastic pad was removed, leaving a reserve space on the dorsal aspect of the foot. The cast was changed every 3–7 days. Typical corrective maneures were performed. Foot displacement into dorsiflexion occured spontaneously as an active motion and also with manipulations. Abduction braces or knee-flexed splints were applied after the complete foot correction. Pirani score and foot dorsiflexion angle were documented during each step of correction. Results. A detailed rating system (with radiologic criteria) was used for result evaluatiion. Correction was successful in all but 5 patients. 90 % required less than 6 casts. There were 12 recurrences and they were related with compliance with the abduction brace, but not with age or number of casts required for correction. Only 13 patients required surgery (6 posterior releases, 6 posteromedial releases and 1 complete subtalar release). Mean follow-up was 12 years. 23% of feet were evaluated as excellent, 71 %- as good and 6%- as poor results. Conclusion. The Furlong method is succesful in obtaining initial correction in the idiopathic clubfoot patient. This method corrects the neonatal congenital clubfoot in 85% without any surgery
