All skeletally immature patients who presented with a supracondylar fracture between 01/09/2013 and 24/11/2015 (n = 50) were used to compare the current management of supra-condylar fractures of the humerus in children to the standards set by the BOAST 11 guidelines. 8.1% did not have full documentation of their neurovascular assessment. 93.9% underwent surgery within 24 hours of presentation. Average time to theatre for neurovascularly compromised patients was 4 hours 46 minutes. 81.8% were managed with 2 K-wires as recommended. Only 39.4% of the patients had their wires removed within 3 – 4 weeks. Only 6.1% had the recommended 2 mm wires. AO recommends the use of 2mm wires if 2 lateral wires are used whereas the BOAST 11 guideline recommends 2mm wires where possible. The results clearly demonstrate a need for further education and awareness of the BOAST 11 guidelines. Of particular interest is the documentation of patients' neurovascular status for appropriate management and for medico-legal purposes. Long term outcome comparison of surgical fixation with 2mm and 1.6mm wires would be useful to support the use of 2mm wires as recommended by the professional consensus in the BOAST 11 guidelines.
The factors that are considered to be associated with successful clinical outcome fallowing cervical arthroplasty surgery are patient selection, absence of facet joint changes and lack of pre-operative kyphosis. Even though many studies have cited the pre-operative demographic details of their patient groups, the effect of associated psychological co-morbidities (Depression/Anxiety), smoking history, gender, social benefits and employment status on the clinical outcome measures have not been reported. The aim of the study was to assess the influence of pre-operative patient characteristics on the clinical outcomes following cervical disc replacement. We included 126 patients who underwent single or multiple level cervical arthroplasty in our unit were included in the study. The clinical outcome measures such as Visual Analogue Score for neck pain (VAS-NP) and arm pain (VAS-AP); Neck disability Index (NDI), Hospital depression and anxiety scale and Bodily pain component of Short Form 36 questionnaires (SF-36 P) were recorded pre and post operatively. Statistical analysis was completed using SPSS 16.0 statistical package (SPSS Inc, Chicago, IL).Background
Methods
The implantation of DIAM in interspinous space is believed to act as facet joints and provides stability to operated segment by shifting instantaneous axis of rotation forward in lordotic disorders. In this retrospective study, the patients who underwent lumbar surgery with DIAM (Medtronic Sofamor, Danek) spacer implants were followed up with an aim to evaluate the clinical outcomes. To our knowledge, this is the largest series with longest follow up. Patients who underwent lumbar surgery (discectomy and decompression) with concomitant placement of DIAM spacer within a 36-months period were included. A total of 52 patients including equal number of male (n=26) and female (n=26), were followed up for 12 to 45 months (Mean: 22 months).Introduction
Material Methods
In the last decade, single level cervical arthroplasty has proven its efficacy as one of the surgical treatment option for for patients suffering from cervical degenerative disc disease. Recent published reports on multilevel cervical arthroplasty using single implants have shown statistically significant results when compared to single level surgery. The aim of this study is to compare the clinical outcomes of multilevel cervical arthroplasty to single level cervical arthroplasty, when more than one type of implants were used. This is a prospective study of consecutive patients who presented to our unit in between June 2006 and November 2009. The maximum follow-up period was 51 months (mean=18 months). Several types of cervical arthroplasty devices have been used in this study. The clinical outcome measures such as Visual Analogue Score for neck pain (VAS-NP) and arm pain (VAS-AP); Neck disability Index (NDI) and the Bodily pain component of Short Form 36 questionnaires were recorded pre and post operatively. After confirming the normality of the data appropriate parametric (paired t-test) were used to assess the statistical significance (p< 0.05) between pre and post-operative values. Two sample T-test was used to assess the significance between the differences in mean scores between each group.Introduction
Methods
This study aims to evaluate the impact of associated psychological co-morbidities (Depression/Anxiety), smoking history, gender, work benefits and employment status on the clinical outcome following anterior cervical disc replacement (ACDR). We included in our study 100 patients who underwent ACDR in our Spinal Unit (between May 2006 – May 2010). We used as clinical outcome measures: Visual Analogue Score for neck pain (VAS-NP) and arm pain (VAS-AP), Neck Disability Index (NDI) and Bodily Pain (SF36-BP) component of the Short Form 36 questionnaire. Statistics were obtained using SPSS 16.0 for Windows (SPSS Inc, Chicago, IL). Independent sample t-test for normally distributed data and Man-Whitney U test for non-parametric data were used. Statistical significance was designated at p < 0.05.Introduction
Materials and Methods
We present the results of a single centre, prospective study to evaluate the clinical and radiographic outcomes of anterior cervical decompression and replacement (ACDR) using the NuNec(tm) Cervical Arthroplasty System (Pioneer Surgical Technology, Marquette, Mich., USA). 36 patients with radiculopathy/myelopathy, who failed to respond to conservative measures, were included. Pain and function were evaluated by Visual Analogue score for Neck pain (VAS-NP) and Arm pain (VAS-AP), Neck disability index (NDI) and SF-36 questionnaires. Radiological assessments include assessing overall range of movement (ROM) and at functional segment unit (FSU). Statistical analysis was completed using SPSS 16.0 statistical package (SPSS Inc, Chicago, IL). Appropriate parametric (A paired t-test) and non parametric tests (Wilcoxon signed-rank test) were used to assess the statistical significance (p<0.05). The average age at operation was 51 years (range 35 - 77years). 8 patients received ACDR at one-level, 15 had 2-level surgery, 12 had 3-level surgery and 1 had a 4-level surgery. At the time of final follow-up (Mean 14.25 months, Range 12- 22.5 months) the mean NDI improved from 49.35; to 33.78 (p< 0.001). There statistically significant improvement note in VAS-NP (Post-op3.65, Pre-op:8.16, p<0.001), VAS-AP (Post-op:3.12, Pre-op:7.32, p<0.001) and SF-36BP (pre-op:29.15, post-op:37.18, p<0.002). The overall global ROM movement was preserved (pre-op:46.80±10.52, post-op:45.04±11.53) and an improvement in ROM at FSU was observed (pre-op:16.60±8.50, post-op:20.22±12.22) at final follow–up.Background
Methodology and Results
We present our experience of 22 patients with low grade degenerative lumbar spondylolysthesis with stenosis (21 Grade I and 1 Grade II) who were treated using new stabilization systems {Scient'x IsoBar TTL Dynamic Rod Stabilization and the Inlign™ Multi-Axial pedicle Screws (Disc Motion Technologies - DMT)}. The pain intensity was evaluated using the Visual Analogue Score for back pain (VAS-BP) and leg pain (VAS-LP) and functional outcomes using Oswestry Disability Score (ODS). Overall improvement in general patient's health was assessed using the Bodily Pain (SF36-BP) component of the SF -36 questionnaires. Data was analysed with the SPSS 16.0 for Windows (SPSS Inc, Chicago, IL). Statistical significance was designated at p < 0.05 and appropriate parametric (Paired sample t-test) and non parametric tests (Wilcoxon signed-rank test) were used. There were 3 male and 19 female patients and average age at operation was 68.95 years (57-79 years). The average duration of follow up was 16.18 months (8-37 months). Most common level of surgery was L4/5 (n=18). Decompression and instrumentation involved 1 level (7 cases), 2 levels (9 cases), 3 levels (1 case) and 4 levels (5 cases). There was statistically significant improvement in all clinical outcomes. The ODS improved from 49.45 ±14.35 pre-operatively to 22.91 ± 6.38 post operatively (p< 0.001). There was statistically significant improvement noted in VAS-BP (p< 0.001), VAS-LP (p<0.001) and SF36-BP (p=0.002).Introduction
Methodology and Results
The purpose of this study is to compare the pre and post-operative magnetic resonance image clarity of titanium and PEEK based cervical arthroplasty devices at the level of implantation and adjacent level discs. This is a prospective, blinded, randomised study on imaging of cervical arthroplasty devices. The pre and postoperative MRI images of 16 patients who underwent cervical arthroplasty using Prestige LP(r) (Medtronic Sofamor Danek) and NuNec(tm) Cervical Arthroplasty System (Pioneer Surgical Technology, Marquette, Mich., USA) were assessed. Two independent radiologists who were blinded and provided with a sets of random images to score using a four point Jarvick grading system. Statistical analysis was completed using SPSS 16.0 statistical package (SPSS Inc, Chicago, IL) and analysis included comparing MR image quality before and after cervical arthroplasty at the operated and adjacent levels, and in between two types of implant. The pre-operative MR image quality at operated and adjacent levels was excellent in both groups. In the post-operative images, the adjacent level visualisation was adequate in both groups without much difference in average scores. However, at operated level, the quality of MR images in the NuNec group (PEEK on PEEK articulating disc) was excellent and clear visualisation of the cord, central canal, foramen and disc.Aim
Methodology and Results
The objective of this study is to assess the effect (if any) of posterior placement of the LP Prestige disc on the motion. To our knowledge this is the first study to assess the relation of posterior placement on the motion.
Statistical analysis showed no statistical significant correlation between the posterior placement of the disc and the motion of disc (flexion to extension, flexion to neural and neutral to extension). The p value was 0.259, 0.379 and 0.623 respectively. There was no correlation between the placement of the disc and the motion of the level above and bellow the operated level.
The pre and post-operative NDI, SF-36, Visual Analogue Score (VAS), HDS and HAS were recorded.
The mean follow up was 28+/−0.35 months, and the mean duration of symptoms was 34.46 +/−3.8 months. Mean length of stay 1.75+/−0.11 (1–4) There was no correlation between the DOS and any of the functional outcome:
Improvement Neck disability index (r=−0.181, p=0.134) Improvement in HDS (r=−0.126, p=0.296) Improvement in HAS (r=0.00, p=0.99) Improvement in SF-36 bodily pain (r=−0.011, p=0.925) Improvement in SF-26 mental health (r=0.042, p=0.324) Improvement in VAS neck pain (r=−0.0120, p=0.324) Improvement in VAS arm pain (r=0.0178, p=0.141) Dividing the DOS into more or less than 12 months shows significant improvement only in the NDI: less than 12 months DOS (31.85±3.209) and in patients with more than 12 months DOS (19.71±2.164), p=0.002 While there was no statistical difference in the other outcomes. Dividing the DOS into more or less than 24 months showed significant improvement the out come in patients with less than 24 months in the following outcomes:
Improvement in NDI: less than 24 months (27.35±2.714), more thank 24 months (19.72+2.435), p=0.04 Improvement in VAS arm pain: less than 24 months (4.6000±0.34446), more than 24 months (2.7414±3.7236), p=0.001 Improvement in hospital depression score: less than 24 months (5.37±0.589), more than 24 months (3.60±0.47), p-0.023 Improvement in hospital anxiety score: less than 24 months (4.28±0.49), more than 24 months (2.45±0.48), p=0.009 While there was no significant difference in the other outcomes Dividing the DOS into less or more than 36 months showed no statistical difference in any of the outcome, That was also the case when the DOS was divided into more or less than 48 months.
The aims of this study were to compare the outcome of epiphysiodesis in patients with limb length discrepancy (LLD) as a result of cerebral palsy with those as a result of other causes in order to test our hypothesis that the hemiplegic / monoplegic limb may respond differently to epiphysiodesis, to evaluate the accuracy of the Moseley method and evaluate whether there is any difference between the outcomes of left or right hemiplegic limbs with LLD bearing in mind that the left hand is used for bone age calculations. We reviewed the case notes and radiographs of 34 children who had undergone epiphysiodesis for the management of LLD by the same surgeon, using the Moseley method between February 1999 and May 2005 to final follow up at skeletal maturity. Of the 34 patients, 9 had a LLD as a result of cerebral palsy (4-Left, 5-Right) and 25 as a result of other causes. In the cerebral palsy group the mean residual LLD was 0.59cm and in the other group it was 1.18cm. Both groups were similar in terms of age and sex distribution. There was no demonstrable statistically significant difference in outcome between the 2 groups (unpaired T test, P=0.734). The Moseley method appeared accurate and there was no difference demonstrated in the outcome between left and right hemiplegic LLD. We conclude that the Moseley method is reliable. We have not found any evidence that the hemiplegic limb behaves any differently. We have not demonstrated any difference in the outcome of left or right hemiplegic limbs.
