Currently, the consensus regarding subscapularis tendon repair during a reverse total shoulder arthroplasty (rTSA) is to do so if it is possible. Repair is thought to decrease the risk of dislocation and improve internal rotation but may also increase stiffness and improvement in internal rotation may be of subclinical benefit. Aim is to retrospectively evaluate the outcomes of rTSA, with or without a subscapularis tendon repair. We completed a retrospective review of 51 participants (25 without and 26 with subscapularis repair) who received rTSR by a single-surgeon using a single-implant. Three patient reported outcome measures (PROM) were assessed pre-operatively and post-operative at twelve months, as well as range of movement (ROM) and plain radiographs. Statistical analysis utilized unpaired t tests for parametric variables and Mann-Whitney U test for nonparametric variables. External Rotation ROM pre-operatively was the only variable with a significance difference (p=0.02) with the subscapularis tendon repaired group having a greater range. Pre- and post-operative abduction (p=0.72 & 0.58), forward flexion (p=0.67 & 0.34), ASES (p=0.0.06 & 0.78), Oxford (p=0.0.27 & 0.73) and post-operative external rotation (p=0.17) Greater external rotation ROM pre-operatively may be indicative of the ability to repair the subscapularis tendon intra-operatively. However, repair does not seem to improve clinical outcome at 12 months. There was no difference of the PROMs and AROMs between the subscapularis repaired and not repaired groups for any of the variables at the pre-operative or 12 month post operative with the exception of the external rotation ROM pre-operatively. We can conclude that from PROM or AROM perspective there is no difference if the tendon is repaired or not in a rTSR and indeed the patients without the repair may have improved outcomes at 12 months.
The reverse total shoulder replacement (rTSR) has excellent clinical outcomes and prosthesis longevity, and thus, the indications have expanded to a younger age group. The use of a stemless humeral implant has been established in the anatomic TSR; and it is postulated to be safe to use in rTSR, whilst saving humeral bone stock for younger patients. The Lima stemless rTSR is a relatively new implant, with only one paper published on its outcomes. This is a single-surgeon retrospective matched case control study to assess short term outcomes of primary stemless Lima SMR rTSR with 3D planning and Image Derived Instrumentation (IDI), in comparison to a matched case group with a primary stemmed Lima SMR rTSR with 3D planning and IDI. Outcomes assessed: ROM, satisfaction score, PROMs, pain scores; and plain radiographs for loosening, loss of position, notching. Complications will be collated. Patients with at least 1 year of follow-up will be assessed. With comparing the early radiographic and clinical outcomes of the stemless rTSR to a similar patient the standard rTSR, we can assess emerging trends or complications of this new device. 41 pairs of stemless and standard rTSRs have been matched, with 1- and 2-year follow up data. Data is currently being collated. Our hypothesis is that there is no clinical or radiographical difference between the Lima stemless rTSR and the traditional Lima stemmed rTSR.
Glenoid baseplate positioning for reverse total shoulder replacements (rTSR) is key for stability and longevity. 3D planning and image-derived instrumentation (IDI) are techniques for improving implant placement accuracy. This is a single-blinded randomised controlled trial comparing 3D planning with IDI jigs versus 3D planning with conventional instrumentation. Eligible patients were enrolled and had 3D pre-operative planning. They were randomised to either IDI or conventional instrumentation; then underwent their rTSR. 6 weeks post operatively, a CT scan was performed and blinded assessors measured the accuracy of glenoid baseplate position relative to the pre-operative plan. 47 patients were included: 24 with IDI and 23 with conventional instrumentation. The IDI group were more likely to have a guidewire placement within 2mm of the preoperative plan in the superior/inferior plane when compared to the conventional group (p=0.01). The IDI group had a smaller degree of error when the native glenoid retroversion was >10° (p=0.047) when compared to the conventional group. All other parameters (inclination, anterior/posterior plane, glenoids with retroversion <10°) showed no significant difference between the two groups. Both IDI and conventional methods for rTSA placement are very accurate. However, IDI is more accurate for complex glenoid morphology and placement in the superior-inferior plane. Clinically, these two parameters are important and may prevent long term complications of scapular notching or glenoid baseplate loosening. Image-derived instrumentation (IDI) is significantly more accurate in glenoid component placement in the superior/inferior plane compared to conventional instrumentation when using 3D pre-operative planning. Additionally, in complex glenoid morphologies where the native retroversion is >10°, IDI has improved accuracy in glenoid placement compared to conventional instrumentation. IDI is an accurate method for glenoid guidewire and component placement in rTSA.
Obesity is an increasing public health concern associated with increased perioperative complications and expense in lumbar spine fusions. While open and mini-open fusions such as transforaminal lumbar interbody fusion (TLIF) and minimally invasive TLIF (MIS-TLIF) are more challenging in obese patients, new MIS procedures like oblique lateral lumbar interbody fusion (OLLIF) may improve perioperative outcomes in obese patients relative to TLIF and MIS-TLIF. The purpose of this study is to determine the effects of obesity on perioperative outcomes in OLLIF, MIS-TLIF, and TLIF. This is a retrospective cohort study. We included patients who underwent OLLIF, MIS-TLIF, or TLIF on three or fewer spinal levels at a single Minnesota hospital after conservative therapy had failed. Indications included in this study were degenerative disc disease, spondylolisthesis, spondylosis, herniation, stenosis, and scoliosis. We measured demographic information, body mass index (BMI), surgery time, blood loss, and hospital stay. We performed summary statistics to compare perioperative outcomes in MIS-TLIF, OLLIF, and TLIF. We performed multivariate regression to determine the effects of BMI on perioperative outcomes controlling for demographics and number of levels on which surgeries were operated. OLLIF significantly reduces surgery time, blood loss, and hospital stay compared to MIS-TLIF, and TLIF for all levels. MIS-TLIF and TLIF do not differ significantly except for a slight reduction in hospital stay for two-level procedures. On multivariate analysis, a one-point increase in BMI increased surgery time by 0.56 ± 0.47 minutes (p = 0.24) in the OLLIF group, by 2.8 ± 1.43 minutes (p = 0.06) in the MIS-TLIF group, and by 1.7 ± 0.43 minutes (p < 0.001) in the TLIF group. BMI has positive effects on blood loss for TLIF (p < 0.001) but not for OLLIF (p = 0.68) or MIS-TLIF (p = 0.67). BMI does not have significant effects on length of hospital stay for any procedure. Obesity is associated with increased surgery time and blood loss in TLIF and with increased surgery time in MIS-TLIF. Increased surgery time may be associated with increased perioperative complications and cost. In OLLIF, BMI does not affect perioperative outcomes. Therefore, OLLIF may reduce the disparity in outcomes and cost between obese and non-obese patients.
There is conflicting evidence about the merits
of mobile bearings in total knee replacement, partly because most randomised
controlled trials (RCTs) have not been adequately powered. We report
the results of a multicentre RCT of mobile There was no significant difference between the groups pre-operatively:
mean OKS was 17.18 ( In this appropriately powered RCT, over the first five years
after total knee replacement functional outcomes, re-operation rates
and healthcare costs appear to be the same irrespective of whether
a mobile or fixed bearing is used. Cite this article:
Patients admitted to trauma wards are routinely screened for MRSA pre-operatively. The majority of them have implant surgery before the screening results were available. The aim of our study was to identify the incidence of MRSA wound infection in these patients and their outcome following it. We randomly reviewed 40 patients who were colonised with MRSA pre-operatively and have had implant surgeries. The case notes, drug charts and the microbiology were reviewed to identify the incidence of MRSA wound infection and its outcome in these patients. The place of residence, site of colonisation and the treatment given were also considered. 70% of the patients were admitted from home and 20% had previous admission within one year. The commonest site colonised is the nose (50%) followed by the perineum in 20%. Multiple sites were colonised in 10% of the patients. Only 50% of them with positive nasal MRSA were given nasal bactroban and chlohexidine wash was given in only 70% of them with MRSA colonisation in other areas. 22.5% (9/40) of the patients developed MRSA infection post operatively and they were treated with vancomycin or teicoplanin. Wound debridement and washout were done in 67.5%. 75% of the MRSA infected wound healed well with no MRSA in the wound site after treatment. 25% of the MRSA infected wounds had persistent MRSA in the wound. As per our study the incidence of MRSA wound infection in patients colonised pre-operatively is about 22.5%. Most cases seem to heal well without much complication with appropriate antibiotics and wound care.
Severely involved patients with spastic diplegia or mild quadriplegia have increasing difficulty remaining ambulatory as they progress to adolescence and young adulthood, often becoming wheelchair bound. This presentation addresses effort to prevent or reverse this progressive state, allowing continued ambulation in a select group of patients. They must be highly motivated to keep walking, have a willingness to undergo extensive rehabilitation and have good psycholsocial support. The program consists of multiple surgeries to the spine, pelvis/hip, knee, foot and ankle followed by a spika or long casts, leg braces (HKAFO to final GRO), 12–18 months of intense physical therapy and permanent use of crutches. Seventeen patients, 16 adilescents and young adults, one adult over 50 adult, who were within 6 months of permanent wheelchair existence qualified and underwent this program. They were followed for a minimum of 10 years post surgery. All patients but one have remained supported community ambulators. The extent of the surgery, complications and problems are described. An additional group of wheelchair bound patients with quandriplegia and severe diplegia were treated with extensive global surgery (described). The purpose was stabile symmetric seating with no pain and allowing the use of the hands and upper extremities for other than support in seating. The ability to achieve these goals has required addressing the controversy associated with extensive surgey in the non-ambulatory patient.
To promote cultural awareness and acceptance of clinical governance by developing a simple, reproducible model for reporting critical incidents and near misses within our department. An A4 sized departmental proforma was developed to parallel the Trust’s official adverse incident register. Prospective reporting of adverse events using the proforma was encouraged between August 2000 and June 2001. Incidents were discussed in an anonymised and a blame-free setting, at the monthly multidisciplinary clinical governance meeting and appropriate action taken. In the 6 months prior to commencing this study only 4 adverse events were reported with no discernible action taken. Following the introduction of the proforma 61 critical incidents and near misses were reported in the period August 2000 to June 2001. As a result of effective reporting of adverse events we have developed a number of protocols to improve patient care. A simple model for reporting critical incidents and near misses has been established. This has fostered a cultural change within the department and all members of staff feel more comfortable with reporting such incidents. The process is seen as educational and an important part of continuing professional and departmental development. Protocols and changes in organisational practice have been developed to reduce and prevent the occurrence of adverse events and offer our patients continuous improvement in care.
To assess whether the ATLS guidelines were being followed within the Accident and Emergency department of a major DGH and suggest a protocol for assessment in future cases. The case records and original X-rays of one hundred sequential patients presenting to the Royal Gwent Hospital who received cervical spine x-rays were reviewed retrospectively. Data sets were recorded for each patient including mechanism of injury, recorded opinion of the cervical spine film, diagnosis within the accident and emergency and discharge or admission. The cervical spine films were then reviewed by the authors and assessed for adequacy of visualisation of the C7-T1 junction as required by the ATLS guidelines. Of the 100 patients 34 of the films assessed were found to have inadequate visualisation of the C7-T1 junction as required by the ATLS guidelines. Swimmers’ views had been obtained in 12 of these patients. The age range was from 9 to 83 years of age. 21 of the 34 had been involved in Road traffic Accidents, 7 in falls, 4 in sport, 1 in an assault and 1 was a case of spontaneous onset neck pain. Diagnoses included neck sprain in 17 cases, bruising in 3 cases, and whiplash in 3 cases. No diagnosis was offered in 11 cases. No specialist opinion was obtained for any of the 34 cases who received inadequate visualisation of their cervical spine. 56 of the 100 patients had satisfactory visualisation of the C7-T1 junction. Films were unavailable for 9 patients. Visualisation of C7-T1 acute cervical trauma can be difficult. The use of swimmers’ views is a helpful adjunct but these can be difficult to interpret. In the absence of adequate visualisation of the C7-T1 junction injury cannot be excluded. A specialist or senior opinion should be sought with recourse to CT or MRI imaging if cervical spine pathology is suspected, but not excluded with initial radiographs.
