The purpose of this prospective audit was to assess the efficacy of local infiltration analgesia in relieving postoperative pain following knee replacement surgery.

Methods and materials: Data was collected on 61 consecutive patients undergoing knee replacement. They formed 2 groups. Patients in Group I (n=33) had 30 mls of Bupivacaine 0.5%, Ketoralac 30 mg, 0.75ml of adrenaline 1:1000 concentration made up to100mls with normal saline while patients in Group II (n=28) had either patient controlled analgesia (PCA) or regional nerve blocks. The group I patients had the local analgesia cocktail infiltrated into the soft tissues before wound closure. Majority of these patients had spinal anaesthesia supplemented with sedation while some had general anaesthesia supplemented with regional nerve blocks. All the patients were prescribed morphine as rescue analgesia and patacetamol/co-codamol and/or naproxene as supplemental analgesia. Pain was assessed with Numerical Rating Scale (NRS 0 – 10) at 1 hr, 3 hr, 6 hr and 8 hrs post-operatively.

Results: The two groups were well matched for age, sex, ASA grade and body mass index. Pain control was generally satisfactory for group I (NRS range 0 – 2) compared to group II (NRS range 0 – 7). Most patients did not require morphine for post-operative pain control in group I (18/27 pts) while additional analgesics were not needed until 6 hours in this group. They were able to mobilise with assistance earlier compared to the other group. Moreover the pain levels as assessed by pain scores were lower with group I patients compared to group II patients. The nursing level of intensity was lower in group I patients as monitoring of PCA was not required compared to group II patients.

Conclusion: Local infiltration analgesia is practical, simple and safe procedure with good efficacy in relieving pain after knee surgery. Moreover monitoring levels are reduced relieving nursing staff to concentrate on other duties.

Aims. This systematic review places a recently completed multicentre randomized controlled trial (RCT), UK FROST, in the context of existing randomized evidence for the management of primary frozen shoulder. UK FROST compared the effectiveness of pre-specified physiotherapy techniques with a steroid injection (PTSI), manipulation under anaesthesia (MUA) with a steroid injection, and arthroscopic capsular release (ACR). This review updates a 2012 review focusing on the effectiveness of MUA, ACR, hydrodilatation, and PTSI. Methods. MEDLINE, Embase, PEDro, Science Citation Index, Clinicaltrials.gov, CENTRAL, and the World Health Organization (WHO) International Clinical Trials Registry were searched up to December 2018. Reference lists of included studies were screened. No language restrictions applied. Eligible studies were RCTs comparing the effectiveness of MUA, ACR, PTSI, and hydrodilatation against each other, or supportive care or no treatment, for the management of primary frozen shoulder. Results. Nine RCTs were included. The primary outcome of patient-reported shoulder function at long-term follow-up (> 6 months and ≤ 12 months) was reported for five treatment comparisons across four studies. Standardized mean differences (SMD) were: ACR versus MUA: 0.21 (95% confidence interval (CI) 0.00 to 0.42), ACR versus supportive care: -0.13 (95% CI -1.10 to 0.83), and ACR versus PTSI: 0.33 (95% CI 0.07 to 0.59) and 0.25 (95% CI -0.34 to 0.85), all favouring ACR; MUA versus supportive care: 0 (95% CI -0.44 to 0.44) not favouring either; and MUA versus PTSI: 0.12 (95% CI -0.14 to 0.37) favouring MUA. None of these differences met the threshold of clinical significance agreed for the UK FROST and most confidence intervals included zero. Conclusion. The findings from a recent multicentre RCT provided the strongest evidence that, when compared with each other, neither PTSI, MUA, nor ACR are clinically superior. Evidence from smaller RCTs did not change this conclusion. The effectiveness of hydrodilatation based on four RCTs was inconclusive and there remains an evidence gap.

Aims. To systematically evaluate whether bracing can effectively achieve curve regression in patients with adolescent idiopathic scoliosis (AIS), and to identify any predictors of curve regression after bracing. Methods. Two independent reviewers performed a comprehensive literature search in PubMed, Ovid, Web of Science, Scopus, and Cochrane Library to obtain all published information about the effectiveness of bracing in achieving curve regression in AIS patients. Search terms included “brace treatment” or “bracing,” “idiopathic scoliosis,” and “curve regression” or “curve reduction.” Inclusion criteria were studies recruiting patients with AIS undergoing brace treatment and one of the study outcomes must be curve regression or reduction, defined as > 5° reduction in coronal Cobb angle of a major curve upon bracing completion. Exclusion criteria were studies including non-AIS patients, studies not reporting p-value or confidence interval, animal studies, case reports, case series, and systematic reviews. The GRADE approach to assessing quality of evidence was used to evaluate each publication. Results. After abstract and full-text screening, 205 out of 216 articles were excluded. The 11 included studies all reported occurrence of curve regression among AIS patients who were braced. Regression rate ranged from 16.7% to 100%. We found evidence that bracing is effective in achieving curve regression among compliant AIS patients eligible for bracing, i.e. curves of 25° to 40°. A similar effect was also found in patients with major curve sizes ranging from 40° to 60° when combined with scoliosis-specific exercises. There was also evidence showing that a low apical vertebral body height ratio, in-brace correction, smaller pre-brace Cobb angle, and daily pattern of brace-wear compliance predict curve regression after bracing. Conclusion. Bracing provides a corrective effect on scoliotic curves of AIS patients to achieve curve regression, given there is high compliance rate and the incorporation of exercises.

Aims. Ankle fractures are common, mainly affecting adults aged 50 years and over. To aid recovery, some patients are referred to physiotherapy, but referral patterns vary, likely due to uncertainty about the effectiveness of this supervised rehabilitation approach. To inform clinical practice, this study will evaluate the effectiveness of supervised versus self-directed rehabilitation in improving ankle function for older adults with ankle fractures. Methods. This will be a multicentre, parallel-group, individually randomized controlled superiority trial. We aim to recruit 344 participants aged 50 years and older with an ankle fracture treated surgically or non-surgically from at least 20 NHS hospitals. Participants will be randomized 1:1 using a web-based service to supervised rehabilitation (four to six one-to-one physiotherapy sessions of tailored advice and prescribed home exercise over three months), or self-directed rehabilitation (provision of advice and exercise materials that participants will use to manage their recovery independently). The primary outcome is participant-reported ankle-related symptoms and function six months after randomization, measured by the Olerud and Molander Ankle Score. Secondary outcomes at two, four, and six months measure health-related quality of life, pain, physical function, self-efficacy, exercise adherence, complications, and resource use. Due to the nature of the interventions, participants and intervention providers will be unblinded to treatment allocation. Conclusion. This study will assess whether supervised rehabilitation is more effective than self-directed rehabilitation for adults aged 50 years and older after ankle fracture. The results will provide evidence to guide clinical practice. At the time of submission, the trial is currently completing recruitment, and follow-up will be completed in 2024.

Aims. Here we used a mature seven-day biofilm model of Staphylococcus aureus, exposed to antibiotics up to an additional seven days, to establish the effectiveness of either mechanical cleaning or antibiotics or non-contact induction heating, and which combinations could eradicate S. aureus in mature biofilms. Methods. Mature biofilms of S. aureus (ATCC 29213) were grown on titanium alloy (Ti6Al4V) coupons for seven days and were subjected to the following treatments or their combinations: antibiotics, mechanical cleaning, or heat shock by induction heating of 60°C for one minute. Experiments were repeated at least five times. Results. In the untreated biofilm, growth up to 1.8×10. 11. colony-forming units (CFU)/cm. 2. was observed. Treatment with ciprofloxacin, flucloxacillin, vancomycin, cefuroxime, and amoxicillin all with rifampicin gave 6.0 log, 6.1 log, 1.4 log, 4.8 log, and 3.6 log reduction in CFU/cm. 2. , respectively. Mechanical cleaning alone resulted in 4.9 log reduction and induction heating in 7.3 log reduction. There was an additional effect of ciprofloxacin, flucloxacillin, and induction heating when used in combinations. There was no additional effect for mechanical cleaning. No bacterial growth could be detected after induction heating followed by seven days of ciprofloxacin with rifampicin. Conclusion. Mechanical cleaning, antibiotics, and non-contact induction heating reduced the bacterial load of mature S. aureus biofilms with approximately 5 log or more as a single treatment. The effect of mechanical cleaning on mature S. aureus biofilms was limited when used in combination with antibiotics and/or induction heating. Cite this article: Bone Joint Res 2022;11(9):629–638

Abstract. BACKGROUND. The effectiveness of anti-embolic graduated compression stockings (GCSs) has recently been questioned. The aim of this study is to systematically review all the relevant randomised controlled trials published to date. PATIENTS AND METHODS. We systematically reviewed all the randomised controlled trials comparing anti-embolism stockings with no stockings. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and CINAHL, Cochrane Musculoskeletal Injuries Group specialized register and the reference lists of articles as well as hand search results. Trials were independently assessed and data for the main outcome measures; deep vein thrombosis (DVT), pulmonary embolism and skin ulceration, were extracted by two reviewers. RESULTS. A total of 26 relevant RCTs involving 8279 participants were systematically reviewed. Theoccurrence of deep vein thrombosis was 306/4159(7.3%) with the stocking to 492/4120(11.9%) without the stockings (RR 0.49, 95% CI 0.39–0.62). The occurrence of pulmonary embolism was also reduced from 1.2% go 0.7% (95% 0.33–0.92). This initial finding was unsound due to the potential underreporting of negative studies and the subsequent changes to clinical practice. For the three large contemporary studies involving 5171 participants, these failed to show any statistically significant reduction in thrombosis, with DVT confirmed in 158(6.1%) participants in those allocated to stocking, as opposed to 171(6.6%) in the control group. CONCLUSION. The current recommendations regarding the use of GCSs need to be reconsidered, as their effectiveness at reducing the occurrence of post-operative DVT is minimal at best, based on the current evidence and clinical practices

An isolated avulsion fracture of the peroneus longus tendon is seldom seen and potentially can go undiagnosed using basic imaging methods during an initial emergency visit. If not managed appropriately it can lead to chronic pain, a reduced range of motions and eventually affect mobility. This article brings to light the effectiveness of managing such injuries conservatively. A 55 year old postman presented to clinic with pain over the instep of his right foot for 2 months with no history of trauma. Clinically the pain was confined to the right first metatarsophalangeal joint with occasional radiation to the calf. X-ray films did not detect any obvious bony injury. MR imaging revealed an ununited avulsion fracture of the base of the 1st metatarsal. The patient was subsequently injected with a mix of steroid and local anesthetic injections at the painful nonunion site under fluoroscopic guidance. Post procedure there was no neurovascular deficit. The patient was reviewed at three months and his pain score and functional outcome improved significantly. Moreover following our intervention, the Manchester Oxford Foot Questionnaire reduced from 33 to 0. At the one year follow up he remained asymptomatic and was discharged. The peroneus longus tendon plays a role in eversion and planter flexion of foot along with providing stabilization to arches of foot. The pattern of injury to this tendon is based on two factors one is the mechanism of insult, if injured, and second is the variation in the insertion pattern of peroneus longus tendon itself. There is no gold standard treatments by which these injuries can be managed. If conservative management fails we must also consider surgery which involves percutaneous fixation, or excision of the non-healed fracture fragment and arthrodesis. To conclude isolated avulsion fractures of peroneus longus tendon are rare injuries and it is important to raise awareness of this injury and the diagnostic and management challenges faced. In this case conservative management was a success in treating this injury however it is important to take factors such as patient selection, patient autonomy and clinical judgement into account before making the final decision

Aim. Multidisciplinary team (MDT) management of complex bone and joint infections (BJI) is increasingly implemented but studies evaluating this approach are scarce. We assessed the effectiveness of our MDT by analyzing the adherence to its treatment decisions. Method. A cohort study was conducted comprising patients with complex BJI of which the management was discussed during MDT meetings between 2015 and 2022 in a tertiary care academic hospital. Patient characteristics and MDT data were obtained from electronic patient records. Results. The analysis included 1321 MDT case decisions on 509 patients. During the study period, the number of patients discussed by the MDT increased from 2.7 to 5.5 per meeting. The percentage of discussed patients with BJI other than prosthetic joint infections (PJI) increased from 26% to 52%. The overall adherence rate to MDT decisions was 92.1%. Reasons for non-adherence were disagreement with the MDT whether cure was achieved or not (34%), new clinical information that was not available during the MDT meeting (12%), preference for suppressive antibiotic treatment over surgery (8%) or not recorded in the patient file (46%). Conclusions. Over the years, the MDT meeting content expanded from mainly PJI to all complex BJI. The high adherence rate to MDT decisions was indicative of an effective MDT. Analysis of adherence is a useful tool to evaluate an MDT and can be used to improve its quality. Different aspects of an MDT need to be evaluated to fully determine its impact and to help improve the care for patients with complex BJI

Abstract. Objectives. To compare the effectiveness of phonophoresis (PH) and conventional therapeutic ultrasound (US) on the functional and pain outcomes of patients with knee osteoarthritis. Methods. We conducted an electronic search through PubMed, Cochrane Central Register of Clinical Trials (CENTRAL), Web of Science (WOS), and Scopus databases. We screened the retrieved articles to include only English full-text randomized controlled trials that examined the effect of phonophoresis versus conventional therapeutic ultrasound on patients with knee osteoarthritis. Two reviewers screened, extracted the data, and independently assessed the quality of the included articles. Results. A total of five randomized controlled trials met our inclusion criteria out of 267 studies screened. Our results showed no statistically significant differences between the PH and US groups (1), (2), (3),(4), and (5). The PH group demonstrated more significant effects than the UT group in reducing VAS pain scores (P=0.009) and improving WOMAC scores, although this did not reach the level of significance (P=0.143) (5). In the long term, PH therapy was found to be superior to US in improving painless walking duration and distance VAS scores (p=0.034, 0.017) respectively, as well as walking and resting walking VAS scores (p=0.03, 0.007) respectively, which were found to be permanent (3). Conclusions. Both therapies improve pain and function. However, we suggest conducting more high-quality trials with larger sample sizes and do not recommend the use of these therapies in clinical practice due to limitations in gender selection and high risk of bias.

Purposes of the study and background. Pain of lumbar facet-joint origin is a common cause of low back pain in adults, and may lead to chronic pain and disability. At present, there is no definitive research to support the use of targeted lumbar facet-joint injections to manage this pain. The study's objective was to assess the feasibility of carrying out a definitive study to evaluate the clinical- and cost-effectiveness of lumbar facet-joint injections compared to a sham procedure. Summary of methods and results. This was a blinded parallel two-arm pilot randomised controlled trial. Adult patients referred to the pain and orthopaedic clinics at Barts Health NHS Trust with non-specific low back pain of at least three months' duration were considered for inclusion. Participants who had a positive result following diagnostic single medial branch nerve blocks were randomised to receive either intra-articular lumbar facet-joint injections with steroid or a sham procedure. All participants were invited to attend a combined physical and psychological programme. Questionnaires were used to assess a range of pain and disability-related issues. Healthcare utilisation and cost data were also assessed. Of 628 participants screened for eligibility, 9 were randomised to receive the study intervention and 8 participants completed the study. Conclusions. Due to the small numbers of participants recruited to the study, we were unable to draw any conclusions on the effectiveness of intra-articular lumbar facet-joint injections in the management of non-specific low back pain. We however demonstrated our ability to develop a robust study protocol and deliver the intended interventions safely, thus addressing many of the feasibility objectives. Stronger collaborations with primary care may improve the recruitment of patients earlier in their pain trajectory, suitable for inclusion in a future trial. Conflicts of interest: None.

There remains much debate regarding the optimal method for surgical management of patients with long head of biceps pathology. The aim of this study was to compare the outcomes of tenotomy versus tenodesis. This systematic review and meta-analysis was registered on PROSPERO (ref: CRD42020198658). Electronic databases searched included EMBASE, Medline, PsycINFO, and Cochrane Library. Randomized controlled trials (RCTs) comparing tenotomy versus tenodesis were included. Risk of bias within studies was assessed using the Cochrane risk of bias v2.0 tool and the Jadad score. The primary outcome included patient reported functional outcome measures pooled using standardized mean difference (SMD) and a random effects model. Secondary outcome measures included pain (visual analogue scale VAS), rate of Popeye deformity, and operative time. 860 patients from 11 RCTs (426 tenotomy vs 434 tenodesis) were included in the meta-analysis. Pooled analysis of all PROMs data demonstrated comparable outcomes between tenotomy vs tenodesis (SMD 0.14, 95% CI −0.04 to 0.32; p=0.13). Sensitivity analysis comparing RCTs involving patients with and without an intact rotator cuff did not change the primary outcome. There was no significant difference for pain (VAS). Tenodesis resulted in a lower rate of Popeye deformity (OR 0.29, 95% CI 0.19 to 0.45, p < 0.00001). Tenotomy demonstrated a shorter operative time (MD 15.21, 95% CI 1.06 to 29.36, p < 0.00001). Aside from a lower rate of cosmetic deformity, tenodesis yielded no measurable significant benefit to tenotomy for addressing pathology in the long head of biceps. A large multi-centre clinical effectiveness randomised controlled trial is needed to provide clarity in this area

Background. Treatment of staphylococcal prosthetic joint infection (PJI) usually consists of surgical debridement and prolonged rifampicin combination therapy. Tailored antimicrobial treatment alternatives are needed due to frequent side effects and drug-drug interactions with rifampicin combination therapy. We aimed to assess the effectiveness of several alternative antibiotic strategies in patients with staphylococcal PJI. Methods. In this prospective, multicenter registry-based study, all consecutive patients with a staphylococcal PJI, treated with DAIR or one-stage revision surgery between January 1. st. , 2015 and November 3. rd. , 2020, were included. Patients were treated according to a predefined protocol for PJI. Antimicrobial treatment strategies differed between centers, which was accepted and used as pseudorandomization. Depending on the hospital patients were admitted to, they were treated with either a long-term rifampicin strategy (consisting of 12 weeks rifampicin combination therapy) ore one of several short-term rifampicin strategies, consisting of only five days of rifampicin combination treatment, started immediately postoperative, followed by clindamycin, flucloxacillin or vancomycin monotherapy. Patients were stratified in different groups, depending on the used antimicrobial strategy. Cox proportional hazards models were used to compare outcome between the groups. Results. Two hundred patients were included and, based on the antimicrobial treatment, stratified in one long-term rifampicin group (n=23) or one of the three short-term rifampicin groups: clindamycin (n=56), flucloxacillin (n=47), vancomycin (n=26), other (n=48). Outcome of PJI after DAIR or one-stage exchange was not statistically different between patients treated with long-term rifampicin combination therapy and patients treated with clindamycin or flucloxacillin monotherapy including only five days of rifampicin combination therapy. Moreover, treatment duration was four weeks shorter in the clindamycin-based and flucloxacillin-based groups. Adjusted hazard ratios for failure for patients treated with either flucloxacillin or clindamycin were almost equal to patients treated with long-term rifampicin combination therapy (aHR 1.21, 95%CI 0.34–4.40). Conclusions. A short-term rifampicin strategy with either clindamycin or flucloxacillin and only five days of rifampicin was found to be as effective as traditional long-term rifampicin combination therapy. A randomized controlled trial is needed to further address efficacy and safety of alternative treatment strategies for staphylococcal PJI

Aims. The present study investigates the effectiveness of platelet-rich plasma (PRP) gel without adjunct to induce cartilage regeneration in large osteochondral defects in a rabbit model. Methods. A bilateral osteochondral defect was created in the femoral trochlear groove of 14 New Zealand white rabbits. The right knees were filled with PRP gel and the contralateral knees remained untreated and served as control sides. Some animals were killed at week 3 and others at week 12 postoperatively. The joints were harvested and assessed by Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) MRI scoring system, and examined using the International Cartilage Repair Society (ICRS) macroscopic and ICRS histological scoring systems. Additionally, the collagen type II content was evaluated by the immunohistochemical staining. Results. After 12 weeks post-surgery, the defects of the PRP group were repaired by hyaline cartilage-like tissue. However, incomplete cartilage regeneration was observed in the PRP group for three weeks. The control groups showed fibrocartilaginous or fibrous tissue, respectively, at each timepoint. Conclusion. Our study proved that the use of PRP gel without any adjuncts could successfully produce a good healing response and resurface the osteochondral defect with a better quality of cartilage in a rabbit model.

Introduction and Objective. Tranexamic acid (TXA) is used across surgical specialties to reduce perioperative bleeding. It has been shown to be effective in trauma, spinal surgery, and lower limb arthroplasty. The aim of this study is to investigate the clinical effectiveness of TXA in all types of shoulder surgery on bleeding and non-bleeding related outcomes. Materials and Methods. This study was registered prospectively on the PROSPERO database (ref: CRD42020185482). A systematic review and meta-analysis of randomised controlled trials (RCTs) investigating intra-operative use of TXA versus placebo in any type of surgery to the shoulder girdle. Electronic databases searched included MEDLINE, EMBASE, PsychINFO, and the Cochrane Library. Risk of bias within studies was assessed using the Cochrane risk of bias v2.0 tool and Jadad score. Certainty of findings were reported using the GRADE approach. The primary outcome was total blood loss. Secondary outcomes included patient reported outcome measures, adverse events, and rate of blood transfusion. Results. Eight RCTs were included in the systematic review and data from 7 of these studies pooled in the meta-analysis. A total of 708 patients were randomized across the studies (406 received TXA, 302 received placebo). Studies included patients undergoing anatomic or reverse total shoulder arthroplasty, open Latarjet surgery, and arthroscopic rotator cuff repair. Pooled analysis demonstrated significant reduction in perioperative bleeding with TXA compared to controls; estimated total blood loss (mean difference [MD], −209.66; 95% CI −389.11 to −30.21; p=0.02), and post-operative blood loss (via drain output) (MD, −84.8ml; 95% CI, −140.04 to −29.56; p=0.003). A mean difference in Visual Analogue Scale (VAS) of 2.93 was noted in favour of TXA (95% CI 0.2 to 5.66; p=0.04). Conclusions. Whilst noting some risk of bias within the studies, TXA was effective in reducing blood loss and pain in shoulder surgery. There may be a benefit of TXA use in both open and arthroscopic shoulder procedures. Larger, low risk of bias, RCTs for specific surgical shoulder procedures are required

Background. Partial facetectomies with pedicle screw instrumentation is widespread and a well described technique for achieving posterior correction of scoliosis. Newton et al. first described the use of the UBS in the posterior correction of AIS in 2014. The aim of this study was to compare the effectiveness of the UBSPO in achieving posterior correction in Type1 AIS as compared to the traditional partial facetectomies. Aim of this study was to assess the effectiveness of USBPO in achieving posterior correction in Type 1 AIS as compared to partial facetectomies. Methods. A retrospective review of 40 patients with type 1 AIS who had undergone a posterior correction of scoliosis between 2010 and 2016 was performed. Group A (n=20) consisted of consecutive patients that had partial facetectomies while Group B (n=20) consisted of consecutive patients having UBSPO. Both groups were matched for demographic parameters. Pre and post-operative radiographic parameters and operative data in both groups were compared. The Mann-Whitney U test was used for statistical analysis. Results. There was no significant difference between the two groups in terms of age, sex, magnitude of curves, apical rotation and flexibility on the preop imaging. There was a significant difference between the mean postop Cobb angle (21.9° vs 9.8°, p<0.0005), correction (63.04% vs 84.3%, p<0.0005) and postop apical rotation (p = 0.008) in favour of the UBSPO group. At 2-year follow-up there was a statistically significant increase in the cobb angle in the facetectomy group (21.89° (immediate post op) Vs 24.64° P=0.033) and no such difference in the UBSPO group. There was no significant difference between surgical time (p = 0.536) and blood loss (p = 0.380). Conclusion. The use of the UBSPO for posterior release provides more effective correction in the coronal and axial planes than traditional partial facetectomies in type 1 AIS

Introduction. In my paediatric Orthopaedic practice I use Kirchner wires for the fixation of the TSF on bone. I noted a significant percentage of wire loosening during the post-operative period. The aim of this project was to establish the effectiveness of the wire clamping mechanism and find ways to reduce the incidence of wire loosening when using the TSF. Materials and Methods. In the first instance wire slippage was measured intra-operatively after the tensioner was removed using an intra-operative professional camera. Following this study mechanical tests were performed in the lab measuring the pull out properties of Kirchner wires using different bolts and different torque levels in order to tighten the wire on the fixator. Results. Our clinical study confirmed wire slippage intra-operatively immediately after the tensioner was removed. Wire slippage after the tensioner was removed was found to vary from 0.01 mm to 0.51 mm (mean 0.19 mm). Our mechanical tests showed that the ideal torque for tightening the wire on the frame using a bolt was around 15 N.m. A comparison between cannulated and slotted bolts suggested that cannulated bolts are more effective as a clamping mechanism. A comparison between aluminium made Taylor Spatial frame rings and stainless steel made Ilizarov rings suggested that the Taylor Spatial frame rings are more effective as part of a clamping mechanism. Conclusions. It is important that clinicians routinely measure the torque they use to clamp wires on circular external fixators. Clinicians and manufacturers are informed that the type of bolt used is important in maintaining wire tension. Manufacturers should design the ideal bolt which effectively grips the wire without the risk of fracture. The Ilizarov frame clamping mechanism can be effectively used with the Taylor Spatial frame

Introduction. Circumferential periosteal release is a rarely reported procedure for paediatric limb lengthening. The technique involves circumferential excision of a strip of periosteum from the metaphysis of the distal femur, tibia and fibula. This study aims to determine the mid to long-term effectiveness of this technique. Materials and Methods. A retrospective case series was performed of all patients undergoing circumferential periosteal release of the distal femur and/or tibia between 2006 and 2017. Data collected included demographics, surgical indication, post-operative limb-lengths and complications. Data collection was stopped if a further procedure was performed that may affect limb-length (except a further release). Leg-length discrepancies were calculated as absolute values and as percentages of the longer limb-length. Final absolute and percentage discrepancies were compared to initial discrepancies using a paired t-test. Results. Eighteen patients (11 males) were identified, who underwent 25 procedures. The mean age at first surgery was 5.83 (SD 3.49). The commonest indication was congenital limb deficiency (13 patients). In 23 procedures the periosteum was released in two limb segments (distal femur and distal tibia), whereas in two patients it was released in a single limb segment. Five patients underwent repeat periosteal release, and one patient had three periosteal releases. Mean follow-up was 63.1 months (SD 33.9). Fifteen patients had sufficient data for statistical analysis. The mean initial absolute discrepancy was 2.01cm (SD 1.13), and the mean initial percentage discrepancy was 4.09% (SD 2.76). The mean final absolute discrepancy was 1.00cm (SD 1.62), and the mean percentage final discrepancy was 1.37% (SD 2.42). The mean reduction in absolute discrepancy was 0.52 cm (95%CI −0.04–1.08; p=0.068, paired t-test), and the mean reduction in percentage discrepancy was 2.00% (95% CI 1.02–2.98, p=<0.001 paired t-test). In five patients the operated limb overgrew the shorter limb. Conclusions. Circumferential periosteal release produces a modest decrease in both absolute and percentage limb-length discrepancy, although the outcome is variable and some patients may experience overgrowth of the operated limb

Summary. Bi-plane Image matching method is very useful technique to evaluate the loaded 3D motion of each cervical level. Introduction. Cervical orthoses are commonly used to regulate the motion of cervical spines for conservative treatment of injuries and for post-operative immobilization. Previous studies have reported the efficacy of orthoses for 2D flex-extension or 3D motions of the entire cervical spine. However, the ability of cervical orthoses to reduce motion might be different at each intervertebral level and for different types of motion (flexion-extension, rotation, lateral bending). The effectiveness of immobilizing orthoses at each cervical intervertebral level for 3D motions has not been reported. The purpose of this study is to evaluate the effectiveness of the Philadelphia collar to each level of cervical spines with 3D motion analysis under loading condition. Patients & Methods. Patient Sample: Four asymptomatic volunteer subjects were recruited and provided informed consent. Approval of the experimental design by the institutional review board was obtained. These 4 individuals were without any history of cervical diseases or procedures. The presence of any symptoms, spinal disorders and anatomical abnormalities in fluoroscopic images or CT was a criterion of exclusion from this study. Outcome Measures: To evaluate the efficacy of the Philadelphia collar, ANOVA was used to compare the range of motion with and without collar at the C3/4, C4/5, C5/6 and C6/7 intervertebral levels for each motion. The level of statistical significance was set at p<0.05. When a statistical difference was detected, post hoc Tukey tests were performed. Methods. Three-dimensional models of the C3-C7 vertebrae were developed from CT scans of each subject using commercial software. Two fluoroscopy systems were positioned to acquire orthogonal images of the cervical spine. The subject was seated within the view of the dual fluoroscopic imaging system. Pairs of images were taken in each of 7 positions: neutral posture, maximum flexion and extension, maximum left and right lateral bending, and maximum left and right rotation. The images and 3D vertebral models were imported into biplane 2D-3D registration software, where the vertebral models were projected onto the pair of digitised images and the 3D bone pose was adjusted to match its radiographic projection in each image. Relative motions between each vertebral body were calculated from body-fixed coordinate systems using a flexion-lateral bending-axial rotation Cardan angle sequence. Results. Flexion range was significantly reduced with the collar at each cervical level. Extension range was significantly reduced at the C3/4 level. Rotation and lateral bending were reduced for C3/4, C4/5, C5/6 levels with the collar. Discussion/Conclusion. The Philadelphia Collar significantly reduces cervical motion at C3/4, C4/5 and C5/6 levels in almost all motions (except for extension). At the C6/7 level, this type of collar has limited effectiveness reducing cervical motion. We used 3D radiographic measurements to quantify the effectiveness of the Philadelphia collar for reducing cervical motion. Bi-plane 2D-3D registration method is useful technique to evaluate 3D motion of cervical spines

Background and objectives. The Alexander Technique (AT) is a self-care method usually taught in one-to-one lessons. AT lessons have been shown to be helpful in managing long-term health-related conditions (Int J Clin Pract 2012;66:98−112). This systematic review aims to draw together evidence of the effectiveness of AT lessons in managing musculoskeletal (MSK) conditions, with empirically based evidence of physiological changes following AT training, to provide a putative theoretical explanation for the observed benefits of Alexander lessons. Methods and results. Systematic searches of a range of databases were undertaken to identify prospective studies evaluating AT instruction for any musculoskeletal condition, using PICO criteria, and for studies assessing the physiological effects of AT training. Citations (N=332) were assessed and seven MSK intervention studies were included for further analysis. In two large well-designed randomised controlled trials, AT lessons led to significant long-term (1 year) reductions in pain and incapacity caused by chronic back or neck pain (usual GP-led care comparator). Three smaller RCTs in chronic back and neck pain, respectively, and a pain clinic service evaluation broadly supported these findings. A pilot study reported preliminary evidence for pain reduction in knee osteoarthritis patients. Further studies showed significant improvements in general coordination, walking gait, motor control and balance, possibly resulting from improved postural muscle tone regulation and adaptability, in people with extensive AT training. Conclusion. Available evidence supports the effectiveness of AT lessons for people with chronic back or neck pain. Studies suggest some of the observed benefit may be due to improvements in movement coordination, balance and postural tone. Conflicts of interest: None. Authors are practising Alexander Technique teachers. Funding: None

Three-dimensional models of the C3–C7 vertebrae were developed from CT scans of each subject using commercial software (see Figure 1). Two fluoroscopy systems were positioned to acquire orthogonal images of the cervical spine. The subject was seated within the view of the dual fluoroscopic imaging system (see Figure 2). Pairs of images were taken in each of 7 positions: neutral posture, maximum flexion and extension, maximum left and right lateral bending, and maximum left and right rotation. The images and 3D vertebral models were imported into biplane 2D-3D registration software, where the vertebral models were projected onto the pair of digitized images and the 3D bone pose was adjusted to match its radiographic projection in each image (see Figure 3). Relative motions between each vertebral body were calculated from body-fixed coordinate systems using a flexion-lateral bending-axial rotation Cardan angle sequence. Results. Flexion range was significantly reduced with the collar at each cervical level. Extension range was significantly reduced at the C3/4 level.
