Introduction. Compartment syndrome can be a life changing consequence of injury to a limb. If not diagnosed and treated early it can lead to permanent disability. Neurovascular observations done on the ward by nursing staff, are often our early warning system to those developing compartment syndrome. But are these adequate for detecting the early signs of compartment syndrome? Our aim was to compare the quality and variability of charts across the UK major trauma network. Materials & Methods. All major trauma centres in England and Scotland were invited to supply a copy of the neurovascular chart routinely used. We assessed how such charts record relevant information. Specific primary data points included were pain scores, analgesia requirements, pain on passive stretch and decreased sensation in the first web space specifically. As secondary objectives, we assessed how late signs were recorded, whether clear instructions were included, quantitative scores and the use of regional blocks recorded. Results. A response rate of 46% was achieved. Of the charts reviewed, 25% documented pain scores or pain on passive movement. Pain on movement and analgesia requirements were documented in 33% and 8% respectively. Specific sensation within the 1. st. webspace was recorded in 16%. No charts recorded use of regional block. All charts recorded global sensation, movement (unspecified), pulse and colour whilst 66% documented capillary refill and 83% temperature. Instructions were included in 41% of charts. Conclusions. In 2016, the BOA supported publication of an observation chart for this purpose however, it is not widely used. In our study, late signs of compartment syndrome were generally well recorded. However, documentation of early signs and regional blocks was poor. This may lead to delays in diagnosis with significant clinical and medicolegal consequences. Standardisation of documentation by updating and promoting the use of the pre-existing chart would ensure highest quality care across the network

Introduction. Snapping hip syndrome is a common condition affecting 10% of the population. It is due to the advance of the iliotibial band (ITB) over the greater trochanter during lower limb movements and often associated with hip overuse, such as in athletic activities. Management is commonly conservative with physiotherapy or can be surgical to release the ITB. Here we carry out a systematic review into published surgical management and present a case report on an overlooked cause of paediatric snapping hip syndrome. Materials & Methods. A systematic review looking at published surgical management of snapping hip was performed according to PRISMA guidelines. PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Library databases were searched for “((Snapping hip OR Iliotibial band syndrome OR ITB syndrome) AND (Management OR treatment))”. Adult and paediatric published studies were included as few results were found on paediatric snapping hip alone. Results. 1548 studies were screened by 2 independent reviewers. 8 studies were included with a total of 134 cases, with an age range of 14–71 years. Surgical management ranged from arthroscopic, open or ultrasound guided release of the ITB, as well as gluteal muscle releases. Common outcome measures showed statistically significant improvement pre- and post-operatively in visual analogue pain score (VAPS) and the Harris Hip Score (HHS). VAPS improved from an average of 6.77 to 0.3 (t-test p value <0.0001) and the HHS improved from an average of 62.6 to 89.4 (t-test p value <0.0001). Conclusions. Although good surgical outcomes have been reported, no study has reported on the effect of rotational profile of the lower limbs and snapping hip syndrome. We present the case of a 13-year-old female with snapping hip syndrome and trochanteric pain. Ultrasound confirmed external snapping hip with normal soft tissue morphology and radiographs confirmed no structural abnormalities. Following extensive physiotherapy and little improvement, she presented again aged 17 with concurrent anterior knee pain, patella mal-tracking and an asymmetrical out-toeing gait. CT rotational profile showed 2° of femoral neck retroversion and excessive external tibial torsion of 52°. Consequently, during her gait cycle, in order to correct her increased foot progression angle, the hip has to internally rotate approximately 35–40°, putting the greater trochanter in an anterolateral position in stance phase. This causes the ITB to snap over her abnormally positioned greater trochanter. Therefore, to correct rotational limb alignment, a proximal tibial de-rotation osteotomy was performed with 25° internal rotation correction. Post-operatively the patient recovered well, HHS score improved from 52.5 to 93.75 and her snapping hip has resolved. This study highlights the importance of relevant assessment and investigation of lower limb rotational profile when exploring causes of external snapping hip, especially where ultrasound and radiographs show no significant pathology

Acute Compartment Syndrome (ACS) is an orthopaedic emergency that can develop after a wide array of etiologies. In this pilot study the MY01 device was used to assess its ease of use and its ability to continuously reflect the intracompartmental pressure (ICP) and transmit this data to a mobile device in real time. This preliminary data is from the lead site which is presently expanding data collection to five other sites as part of a multi-center study. Patients with long bone trauma of the lower or upper extremity posing a possibility of developing compartment syndrome were enrolled in the study. Informed consent was obtained from the patients. A Health Canada licensed continuous compartmental pressure monitor (MY01) was used to measure ICP. The device was inserted in the compartment that was deemed most likely to develop ACS and ICP was continuously measured for up to 18 hours. Fractures were classified according to the AO/OTA classification. Patient clinical signs and pain levels were recorded by healthcare staff during routine in-patient monitoring and were compared to the ICP from the device. Important treatment information was pulled from the patient's chart to help correlate all of the patient's data and symptoms. The study period was conducted from November 2020 through December 2021. Twenty-six patients were enrolled. There were 17 males, and nine females. The mean age was 38 years (range, 17–76). Seventeen patients received the device post-operatively and nine received it pre-operatively. Preliminary results show that post-operative ICPs tend to be significantly higher than pre-operative ICPs but tend to trend downwards very quickly. The trend in this measurement appears to be more significant than absolute numbers which is a real change from the previous literature. One patient pre-operatively illustrated a steep trend upwards with minimal clinical symptoms but required compartment release at the time of surgery that exhibited no muscle necrosis. The trend in this patient was very steep and, as predicted, predated the clinical findings of compartment syndrome. This trend allows an early warning signal of the absolute pressure, to come, in the compartment that is being assessed by the device. Preliminary results suggest that this device is reliable and relatively easy to use within our institutions. In addition it suggests that intracompartmental pressures can be higher immediately post-op but lower rapidly when the patient does not develop ACS. These results are in line with current literature of the difference between pre and post-operative baselines and thresholds of ICP, but are much more striking, as continuous measurements have not been part of the data set in most of past studies. Further elucidation of the pressure thresholds and profiles are currently being studied in the ongoing larger multicenter study and will add to our understanding of the critical values. This data, plus the added value of continuous trends in the pressure, upwards or downwards, will aid in preventing muscle necrosis during our management of these difficult long bone fractures

Aims. Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in a motor impairment affecting the upper limbs more than the lower limbs, with occasional sensory impairment and urinary retention seen. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study is to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age. Patients and Methods. Patients ≥18 years with traumatic CCS between January 2012 and December 2017 in Wales were identified. Patient demographics and injury, management and outcome data was collected. Statistical analysis was performed to assess mortality and between group differences. Results. 65 patients were identified (66.2% male, mean age 63.9 years). At five-years follow-up, 32.3% (n=21) of CCS patients were dead. 6 (9.2%) patients had died within 31 days of their injury. 69.2% (n=45) of patients were managed conservatively and there was no significant difference (p=0.062) in age between conservatively and surgically managed patients. Kaplan-Meier analysis revealed no significant difference in mortality between patients managed conservatively compared to those managed surgically (log rank test, p=0.819). However, there was a significant difference (p=0.001) in mortality between the different age groups (<50 years vs 50–70 years vs >70 years). At five-years follow up, 55.6% of the patient group aged >70 years at time of injury were dead. Respiratory failure was the most common cause of death (n=9, 42.9%). Conclusion. Almost one third of patients with traumatic CCS in Wales were dead at five years following their injury. Management type did not significantly affect mortality, however age at time of injury did. Further work assessing the long-term functional outcomes of surviving patients is needed, to allow more reliable prognostic information and functional recovery predictions to be given

The best algorithm, measurements, and criteria for screening children with Down syndrome for upper cervical instability are controversial. Many authors have recommended obtaining flexion and extension views. We noted that patients who require surgical stabilization due to myelopathy or cord compression typically have grossly abnormal radiographic measurements on the neutral upright lateral cervical spine radiograph (NUL). This study was designed to determine whether a full series of cervical spine images including flexion/extension lateral radiographs (FEL) was important to avoid missing upper cervical instability. This is a retrospective evaluation of cervical spine images obtained between 2006 and 2012 for the purposes of “screening” children with Down syndrome for evidence of instability. The atlanto-dental interval, space available for cord, and basion axial interval were measured on all films. The Weisel-Rothman measurement was made in the FEL series. Clinical outcome of those with abnormal measurements were reviewed. Sensitivity, specificity, positive and negative predictive values of NUL and FEL x-rays for identifying clinically significant cervical spine instability were calculated. Two-hundred and forty cervical spine series in 213 patients with Down syndrome between the ages of four months and 25 years were reviewed. One hundred and seventy-two children had a NUL view, and 88 of these patients also had FEL views. Only one of 88 patients was found to have an abnormal ADI (≥6mm), SAC (≤14mm), or BAI (>12mm) on an FEL series that did not have an abnormal measurement on the NUL. This patient had no evidence of cord compression or myelopathy. Obtaining a single NUL x-ray is an efficient method for radiographic screening of cervical spine instability. Further evaluation may be required if abnormal measurements are identified on the NUL x-ray. We also propose new “normal” values for the common radiographic measurements used in assessing risk of cervical spine instability in patients with Down syndrome

To compare the efficacy of local steroid injection with surgical decompression in treatment of carpal tunnel syndrome (CTS) in terms of frequency of pain. This randomized controlled study was conducted at the Department of Orthopaedics for a duration of 01 year, i.e. from 20th April 2016 to 19th April 2017. 130 patients with carpal tunnel syndrome with moderate (Grade 2) and severe (Grade 3) pain were included. Lottery method was used to allocate the patients randomly into two groups. Group A contained 65 patients who were subjected to surgical decompression and 65 patients were in Group B who were injected with local steroid injection. Complete history was obtained from all patients. All the surgical decompressions through mini incision technique and injections procedures were performed. Information were recorded in a pre designed Performa. Efficacy was observed significantly high in group B as compared to group A (87.7% vs. 72.3%, p=0.028). Carpal Tunnel syndrome symptoms were alleviated with surgical decompression as well as local steroid injection at a follow up done after 1 month. However the steroid injections seem to have greater efficacy than surgical decompression, hence we suggest it for routine treatment of all patients with CTS.

We undertook this study to investigate the outcomes of surgical treatment for acute carpal tunnel syndrome following our protocol for concurrent nerve decompression and skeletal stabilization for bony wrist trauma to be undertaken within 48-hours. We identified all patients treated at our trauma centre following this protocol between 1 January 2014 and 31 December 2019. All patients were clinically reviewed at least 12 months following surgery and assessed using the Brief Michigan Hand Outcomes Questionnaire (bMHQ), the Boston Carpal Tunnel Questionnaire (BCTQ) and sensory assessment with Semmes-Weinstein monofilament testing. The study group was made up of 35 patients. Thirty-three patients were treated within 36-hours. Patients treated with our unit protocol for early surgery comprising nerve decompression and bony stabilization within 36-hours, report excellent outcomes at medium term follow up. We propose that nerve decompression and bony surgical stabilization should be undertaken as soon as practically possible once the diagnosis is made. This is emergent treatment to protect and preserve nerve function. In our experience, the vast majority of patients were treated within 24-hours

Significant hip osteoarthritis has been reported in 8–28% of patients with Down Syndrome. The prolonged life expectancy of these patients has allowed many of them to become disabled by their hip arthritis with the need for hip replacement. We have been able to perform a multi-center study evaluating total hip replacement in patients with Down Syndrome. Twenty patients (25 hips) with Down Syndrome underwent primary THA at a mean age of 35 years old with a mean 105-month follow-up. Cementless acetabular fixation with screws were used in all cases and all but one femoral component was cementless. Constrained liners were used in 8 cases to enhance stability. Five hips required revision surgery: two femoral components (one for periprosthetic fracture and one for aseptic loosening), two acetabular components (one for recurrent dislocation and one for wear with metallosis), and one hip required a two-stage revision for infection. Other than the hip revised for loosening, no other hip had radiographic evidence of loosening. The mean Harris Hip score improved from 42 points pre-operatively to 83 points at final follow-up. THA is a reliable surgical intervention in patients with Down Syndrome and symptomatic coxarthrosis. These patients and their families have been tremendously satisfied with this procedure. Strategies to prevent dislocation post THA are appropriate and need continued evaluation

In Asia, traditional bands are placed around limbs of children to ward off evil spirits and ensure good health. This practice may lead to the Rubber Band Syndrome (RBS) a rare paediatric condition described mainly in Asia which results from a forgotten thread or elastic band applied to the limb of a child. Because pressure necrosis beneath the band is slow, rapid healing of tissues over the band can obscure its presence. This makes the condition difficult to diagnose and distinguish from other infective conditions. This study presents the first case of RBS reported in South Africa. Case: The patient aged 18 months presented with a swollen hand, circumferential scar and discharging sinus on the wrist. A radiograph was negative. In theatre the volar wound was explored. Debridement revealed a yellow rubber band deep to the wrist flexors and neurovascular bundles but superficial to the extensor retinaculum. Complete removal of the rubber band and antibiotics was followed by rehabilitation with Occupational Therapy. At a 3 month follow up, there was no evidence of infection, sensation was normal and motor function of the hand restored. In this case, the structures through which the band had already passed were intact and overlay the band. It would appear that as the band slowly eroded the underlying structures it was followed by healing along the tract until the band exited deep to these structures. The band may come to rest on bone causing osteomyelitis if allowed to progress. A high index of suspicion of RBS is needed in children presenting with a circumferential scar and a non-healing wound, especially on the wrist or ankle. Careful debridement and complete removal of the band are essential to resolve symptoms and restore function

Down syndrome (DS), is a genetic disorder caused by a third copy of the 21st chromosome (Trisomy 21), featuring typical facial characteristics, growth delays and varying degrees of intellectual disability. Some degree of immune deficiency is variably present. Multiple orthopaedic conditions are associated, including stunted growth (90%), ligamentous laxity (90%), low muscle tone (80%), hand and foot deformities (60%), hip instability (30%), and spinal abnormalities including atlanto-axial instability (20%) and scoliosis. Hip disease severity varies and follows a variable time course. Rarely a child presents with DDH, but during the first 2 years the hips are characteristically stable but hypermobile with well-formed acetabulae. Spontaneous subluxation or dislocation after 2 presents with painless clicking, limping or giving way. Acute dislocation is associated with moderate pain, increased limp and reduced activity following minor trauma. Hips are reducible under anesthesia, but recurrence is common. Eventually concentric reduction becomes rarer and radiographic dysplasia develops. Pathology includes: a thin, weak fibrous capsule, moderate to severe femoral neck anteversion and a posterior superior acetabular rim deficiency. A number of femoral and acetabular osteotomies have been reported to treat the dysplasia, with acetabular redirection appearing to be most successful. However, surgery can be associated with a relatively high infection rate (20%). Additionally, symptomatic femoral head avascular necrosis can occur as a result of slipped capital femoral epiphysis. Untreated dysplasia patients can walk with a limp and little pain into the early twenties even with fixed dislocation. Pain and decreasing hip function is commonly seen as the patient enters adult life. Occasionally the hip instability begins after skeletal maturity. Total hip arthroplasty (THA) is the standard treatment when sufficient symptoms have developed. The clinical outcomes of 42 THAs in patients with Down syndrome were all successfully treated with standard components. The use of constrained liners to treat intra-operative instability occurred in eight hips and survival rates were noted between 81% and 100% at a mean follow-up of 105 months (6 – 292 months). A more recent study of 241 patients with Down syndrome and a matched 723-patient cohort from the Nationwide Inpatient Sample compared the incidence of peri-operative medical and surgical complications in those who underwent THA. Compared to matched controls, Down syndrome patients had an increased risk of complications: peri-operative (OR, 4.33; P<.001), medical (UTI & Pneumonia OR, 4.59; P<.001) and surgical (bleeding OR, 3.51; P<.001), Mean LOS was 26% longer (P<.001). While these patients can be challenging to treat, excellent surgical technique and selective use of acetabular constraint can reliably provide patients with excellent pain-relief and improved function. Pre-operative education of all clinical decision makers should also reinforce the increased risk of medical and surgical complications (wound hemorrhage), and lengths of stay compared to the general population

To describe the longitudinal trends in patients with obesity and Metabolic Syndrome (MetS) undergoing TKA and the associated impact on complications and lengths of hospital stay. We identified patients who underwent primary TKA between 2006 – 2017 within the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. We recorded patient demographics, length of stay (LOS), and 30-day major and minor complications. We labelled those with an obese Body Mass Index (BMI ≥ 30), hypertension, and diabetes as having MetS. We evaluated mean BMI, LOS, and 30-day complication rates in all patients, obese patients, and those with MetS from 2006-2017. We used multivariable regression to evaluate the trends in BMI, complications, and LOS over time in all patients and those with MetS, and the effect of BMI and MetS on complication rates and LOS, stratified by year. 270,846 patients underwent primary TKA at hospitals participating in the NSQIP database. 63.71% of patients were obese (n = 172,333), 15.21% were morbidly obese (n = 41,130), and 12.37% met criteria for MetS (n = 33,470). Mean BMI in TKA patients increased at a rate of 0.03 per year (0.02-0.05; p < 0 .0001). Despite this, the rate of adverse events in obese patients decreased: major complications by an odds ratio (OR) of 0.94 (0.93-0.96; p < 0 .0001) and minor complications by 0.94 (0.93-0.95; p < 0 .001). LOS also decreased over time at an average rate of −0.058 days per year (-0.059 to −0.057; p < 0 .0001). The proportion of patients with MetS did not increase, however similar improvements in major complications (OR 0.94 [0.91-0.97] p < 0 .0001), minor complications (OR 0.97 [0.94-1.00]; p < 0 .0330), and LOS (mean −0.055 [-0.056 to −0.054] p < 0 .0001) were found. In morbidly obese patients (BMI ≥ 40), there was a decreased proportion per year (OR 0.989 [0.98-0.994] p < 0 .0001). Factors specifically associated with major complications in obese patients included COPD (OR 1.75 [1.55-2.00] p < 0.0001) and diabetes (OR 1.10 [1.02-1.1] p = 0.017). Hypertension (OR 1.12 [1.03-1.21] p = 0.0079) was associated with minor complications. Similarly, in patients with MetS, major complications were associated with COPD (OR 1.72 [1.35-2.18] p < 0.0001). Neuraxial anesthesia was associated with a lower risk for major complications in the obese cohort (OR 0.87 [0.81-0.92] p < 0.0001). BMI ≥ 40 was associated with a greater risk for minor complications (OR 1.37 [1.26-1.50] p < 0.0001), major complications (1.11 [1.02-1.21] p = 0.015), and increased LOS (+0.08 days [0.07-0.09] p < 0.0001). Mean BMI in patients undergoing primary TKA increased from 2006 - 2017. MetS comorbidities such as diabetes and hypertension elevated the risk for complications in obese patients. COPD contributed to higher rates of major complications. The obesity-specific risk reduction with spinal anesthesia suggests an improved post-anesthetic clinical course in obese patients with pre-existing pulmonary pathology. Encouragingly, the overall rates of complications and LOS in patients with obesity and MetS exhibited a longitudinal decline. This finding may be related to the decreased proportion of patients with BMI ≥ 40 treated over the same period, possibly the result of quality improvement initiatives aimed at delaying high-risk surgery in morbidly obese patients until healthy weight loss is achieved. These findings may also reflect increased awareness and improved management of these patients and their elevated risk profiles

We all aware about overuse syndrome, as compensation of other parts of body. Our famous poet Sa'adi: when part of our body sustains become painful, the other parts can't tolerate and reciprocate. Among our patients who underwent total Knee arthroplasty few of them have pain especially in 1st 3 months (Anterior Knee pain, effusion, ….) but almost 15 – 20 percents are not satisfied enough by this Procedure. In a Cohort historic study on 301 TKA with at least 2 years follow up 47 patients had not enough satisfaction in our clinic we tried to visit them to find out why?. Criteria's we chose, were:. Age. Osteopenia. Sarcopenia. Low back pain. Spinal canal stenosis. Shoulders. Unstable blood pressure. Neuropathy. Eyes dysfunction. We exclude those who had problem by their new knees. 11 patients, all have been over age 68 years, and duration of start of symptoms in knee (s) to the surgery were more than 12 years, clearly showed painful arch of shoulder motion or frozen shoulder or established gleno humeral alone or G.H. and A.C. joints OA. Conclusion. Because of abnormal stand up of long lasting knee OA patients, they start to put pressure on their shoulder to climb on their body. Even their cane or crutches use are not in regular and academic rules. So, we nominate this entity: shoulder knee syndrome as a negative criteria that interferes in out come

Introduction. Torsional malalignment syndrome (TMS) is a unique combination of rotational deformities in the lower limb, often leading to severe patellofemoral joint pain and disability. Surgical management of this condition usually consists of two osteotomies in each affected limb, with simultaneous correction of both femoral anteversion and external tibial torsion. However, we believe that a single supratubercular osteotomy followed by tibial derotation with the Taylor Spatial Frame (TSF) can be used to provide a significant improvement in both appearance and function. Materials and Methods. This is a retrospective case analysis in which we will be reviewing 16 osteotomies performed by one surgeon between 2006 and 2017. The study includes 11 patients with a mean age of 16.7 ± 0.8 years. Pre and post-operatively, patients were fully evaluated through history and physical examination, and CT rotational profiling. Statistical analyses were performed in order to determine whether or not any observed clinical or cosmetic improvements were statistically significant. Results. The results show significant improvements in scores reported on post-operative functional assessment, with mean Oxford Knee Score (OKS) increasing by 18.3 and mean Kujala Anterior Knee Pain Scale (AKPS) also increasing by 31.4. In addition to this, post-operative clinical assessment showed a reduced thigh-foot angle (TFA) in all cases, by a mean value of 31.9o. The angle of the transmalleolar axis (TMA) was successfully reduced in 14/16 cases, by a mean value of 8.6o. Statistical analysis showed all of these results to be statistically significant where p<0.05. Conclusions. The results show that supratubercular osteotomy, followed by gradual correction with TSF, can be used to provide a significant improvement in both appearance and function for patients suffering from TMS

There is an increased incidence of dislocation, dysplasia, slipped epiphysis, Perthes’ disease, and avascular necrosis leading to degenerative arthritis which occurs in up to 28% of Down's syndrome patients. As the life expectancy for patients with Down's syndrome has increased, so has the presence of hip disease. Hip replacement has been shown to have good results in this population. Special considerations include a high risk of postoperative dislocation and leg length inequality which often require large head THR or dual mobility type reconstruction to reduce these risks. Numerous spine deformities including scoliosis and C1-2 subluxation need to be taken into account-anesthesia consult

Abstract. Background. Cauda equina syndrome (CES) is a rare serious condition that, if missed at initial presentation, can lead to serious disability. Early diagnosis is crucial for a favourable outcome. Few studies included urodynamic test and measurement of post-void residual urine (PVR) as an adjunct screening tool for acute CES before proceeding to MRI scan, yet there are differences in the cut-off point as a threshold volume to be considered as a red flag for doing MRI amongst these studies. Aim. Meta-analysis and systematic review of literature that included PVR as a predictive tool in CES to identify the reliability of PVR and the optimal numerical value to be considered as red flag. Material & Methods. A comprehensive literature search was undertaken in PubMed, Medline, and Embase databases using our search strategy. Meta-analysis of collated data. Results. A total of seven studies were included with a total of 938 patients. The number of cases suitable for meta-analysis was 714. CES was confirmed in 73. urodynamic testing and PVR diagnosed 86 and excluded 426. The sensitivity of PVR>100ml was 64% (CI 97.5%: 0.44–0.80), specificity 59.2% (CI 97.5%: 0.46 – 0.711), while PVR >200 showed more predictive figures, with sensitivity improved to 83.1% (CI 97.5%: 0.62–0.94) and specificity to 93.5% (CI 97.5%: 0.50–0.99). Conclusions. Urodynamics test is an essential tool in CES assessment. Authors recommend PVR > 200 ml as the numerical cut-off point to be considered as a red flag that if present with other clinical red flags, urgent MRI is recommended in suspected CES

Hip osteoarthritis is prevalent in 8%–28% of patients with Down's Syndrome. Presence of disabling hip pain is increased along with prolonged life expectancy, suggesting total hip arthroplasty (THA). Seven consecutive patients (9 hips) with Down's syndrome had primary THA. Coxarthrosis was secondary to developmental hip dysplasia in 6 patients and slipped capital epiphysis in 1 patient. In 5 patients (7 hips) a previous hip surgery was performed. Average clinical and radiological follow up was 9.9 ± 6.4 years (range 2–22.5, median 9.3). Average age of patients at THA was 34.8 ± 7.5 years (range 25–47, median 35.4). In 2 patients (3 hips) a trochanteric slide was used for the surgical approach, while a lateral transgluteal approach was used in the remaining patients. One way ANOVA test was used to compare Harris Hip Scores (HHS) at post-operative follow-up. HHS improved significantly (p=0.008) improved from 4.1 ± 15.1 (range 18.5–65, median 45) to 84.3 ± 7.7 (range 70–93, median 85.8 at 4 year follow up. HHS (average 70.9 ± 6.2, range 66.5–80, median 68) remained essentially unchanged (p=0.43) at 8 year follow-up. Two patients required revision arthroplasty for stem loosening at 6 and 16 years post THA, respectively. The first patient is 7 years post revision and ambulates without aids. The second patient is 6.1 years post revision and ambulates with a walker. Six of the THAs required a constrained liner. No dislocations or deep infections were encountered. THA is reliable surgical intervention in patients with Down's Syndrome and symptomatic coxarthrosis

The purpose of this study is to report a unique overgrowth syndrome and discuss the insights into the complex orthopaedic management. Written consent to report this case was granted. The patient's condition, wrongly diagnosed as Proteus syndrome, is characterised by a genetic mutation in PIK3CA, a critical regulator of cell growth. This lead to unregulated cellular division of fibroblasts isolated to the lower limbs. The legs weighed 117 kg, with a circumference of >110 cm. In addition to lower limb overgrowth, numerous musculoskeletal and organ pathologies have been encountered since birth requiring treatment from a wide variety of healthcare specialists and basic scientists. At 32 years, the patient developed septicaemia secondary to an infected foot ulcer. Amputation had been discussed in the elective setting, however the presence of sepsis expedited surgery. The above knee amputation took 9 hours and four assistants including a plastic surgeon. A difficult dissection revealed a deep subcutaneous fatty layer that integrated with deep muscle, massive hypertrophy of cutaneous nerves and the sciatic nerve and ossification within the distal quarter of the quadriceps muscles requiring osteotomy. The lower limb osteology was grossly aberrant. The size of the amputated limb did not permit use of a tourniquet and cell salvage reintroduced 10.5 litres of blood with a further 6 units of red cells intra-operatively. The leg stump successfully took to a split-skin graft. A unique phenomenon was witnessed post-operatively whereby the stump continued to grow due to upregulation of fibroblasts secondary to trauma. Targeted genetic therapies have been successfully developed to suppress this stump growth. This unique and unclassified overgrowth syndrome was caused by a mutation in the PIK3CA gene. Orthopaedic management of the oversized limb was complex requiring multiple surgeons and prolonged general anesthetic. A multi-disciplinary approach to this condition is required for optimizing outcomes in these patients

Purpose. Compartment syndrome is a limb threatening condition. Prior research has been limited by an inability to assess functional and histologic changes in muscle over time. This study was designed to assess and quantify functional deficits and histologic changes following acute compartment syndrome of the lower limb in a novel rat model. Method. Twenty-three male Wistar rats were trained to perform an incentive-based standard task on an optical gait tracking system. Animals were then randomized to three groups: Control (n=4), Sham (n=4) and Compartment Syndrome (CS, n=15). Control and sham animals had no elevation of intracompartmental pressure, while CS animals had elevated intracompartmental pressure to 30mmHg for 180 minutes in the anterior compartment of the left hind limb using a saline infusion technique. Following intervention, gait analysis was performed at 2hrs, 24hrs, 48hrs, 72hrs and 7days following injury. Several parameters for the injured hind limb were analyzed including: print area, print intensity, maximum contact timing, duty cycle and stance phase time. A 2-way ANOVA with Bonferroni post-hoc analysis was performed. The EDL muscle was harvested (n=17), fixed in formalin and prepared with an H&E stain. Mid-muscle sections were analyzed by a blinded senior pathologist for cell infiltration, necrosis and regeneration. Results. Function Changes: Mean print intensity was 96.5518.7 at 48hrs for CS animals, compared to 145.538.2 in control animals and 144.9612.71 in sham animals (p<0.001). At the 2hrs, 24hrs, and 48hrs time intervals post injury the CS animals showed significant decreases in print width (p<0.001), maximum contact (p<0.001), mean print intensity (p<0.001) and stance phase (p<0.01). There were no significant differences between baseline and 72hr results for any gait parameter (p>0.05). Histologic Changes: Cellular infiltration was noted at 24hrs, peaked at 48hrs and was still present at 7 days to a lesser degree. Necrosis began as early as 24hrs post injury and also peaked by 48hrs and returned to baseline levels by 7days. Minor regenerative changes were identified as early as 24hrs however the majority of changes were identified at 7 days post-injury. Conclusion. Developing and evaluating animal models for the study of compartment syndrome is essential for better understanding the condition and testing new treatment modalities. Gait analysis was a reproducible means of assessing function after compartment syndrome. Animals demonstrated an antalgic gait pattern demonstrated by decreased stance phase, decreased print intensity, and increased print width, with recovery demonstrated by 72hrs post-injury. Defining the histologic changes such as necrosis, cellular infiltration and regeneration associated with compartment syndrome has allowed us to further understand the evolving pathology of compartment syndrome over time. This study facilitates the evaluation of functional and histologic testing for the evaluation of new therapeutic interventions

Background. Shoulder impingement syndrome (SIS) is a common debilitating condition, treated across multiple health disciplines including Orthopaedics, Physiotherapy, and Rheumatology. There is little consistency in diagnostic criteria with ‘Shoulder impingement syndrome’ being used for a broad spectrum of complex pathologies. We assessed patterns in diagnostic procedures for SIS across multiple disciplines. Methods. This is a systematic review of electronic databases MEDLINE, PubMed, The Cochrane Library, Embase, Scopus and CINAHL five years of publications, January 2009 - January 2014. Search terms for SIS included subacromial impingement syndrome, subacromial bursitis. Searches were delimited to articles written in English. The PRISMA guidelines were followed. Two reviewers independently screened all articles, data was then extracted by one reviewer and twenty percent of the extraction was independently assessed by the co-reviewer. Studies included were intervention studies examining individuals diagnosed with SIS and we were interested in the process and method used for the diagnosis. Results. The search strategy yielded 3339 articles of which 1931 were duplicates. A further 1260 were excluded based on relevance obtained from title/abstract. A total of 148 articles were identified investigating SIS across thirty different journals internationally. Fourteen different health disciplines have investigated twenty-five different surgical and conservative treatments. Studies document their diagnostic approach, reporting on duration of symptoms, medical history, physical examination tests and radiological investigations. Duration of symptoms for inclusion ranged from a minimum of 2 weeks to 18 months where the median duration of symptoms is 3 months observed in 46 percent of the studies. Commonly used physical tests were Neer's test, Hawkins-Kennedy test, Jobe and Yocum, and a further eight tests identified. Neer's test or Hawkins-Kennedy tests were individually used in 72 percent of studies. Thirty of the studies used more than one and up to six physical tests per study to determine the presence of impingement. Radiological investigations were reported in twenty-eight studies, sixteen of these required more than one radiological investigation to confirm the diagnosis of SIS. Comparisons between disciplines identify important differences in diagnostic criteria used by different health professionals. Conclusions. This study highlights the variety of diagnostic methods which are currently used between health disciplines and will be a useful comparative tool for clinicians. Diagnostic transparency is pertinent for shoulder impingement syndrome to ensure all disciplines are treating the same pathology and importantly to contribute to our understanding of the common pathology
