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.

Dislocation of the acromioclavicular joint is a relatively common injury and a number of surgical interventions have been described for its treatment. Recently, a synthetic ligament device has become available and been successfully used, however, like other non-native solutions, a compromise must be reached when choosing non-anatomical locations for their placement. This cadaveric study aimed to assess the effect of different clavicular anchorage points for the Lockdown device on the reduction of acromioclavicular joint dislocations, and suggest an optimal location. We also assessed whether further stability is provided using a coracoacromial ligament transfer (a modified Neviaser technique). The acromioclavicular joint was exposed on seven fresh-frozen cadaveric shoulders. The joint was reconstructed using the Lockdown implant using four different clavicular anchorage points and reduction was measured. The coracoacromial ligament was then transferred to the lateral end of the clavicle, and the joint re-assessed. If the Lockdown ligament was secured at the level of the conoid tubercle, the acromioclavicular joint could be reduced anatomically in all cases. If placed medial or 2 cm lateral, the joint was irreducible. If the Lockdown was placed 1 cm lateral to the conoid tubercle, the joint could be reduced with difficulty in four cases. Correct placement of the Lockdown device is crucial to allow anatomical joint reduction. Even when the Lockdown was placed over the conoid tubercle, anterior clavicle displacement remained but this could be controlled using a coracoacromial ligament transfer.

Background

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.

Introduction

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.

Introduction

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.

Introduction

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).

Background

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).

Introduction

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)}.

Aim

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.

Recurrence of back or leg pain after discectomy is a well-recognised problem with an incidence of up to 28%. Once conservative measures have failed, several surgical options are available and have been tried with varying degrees of success. In this study, 42 patients with recurrent symptoms after discectomy underwent less invasive posterior lumbar interbody fusion (LI-PLIF). Clinical outcome was measured using the Oswestry Disability Index (ODI), Short Form 36 (SF-36) questionnaires and visual analogue scales for back (VAS-BP) and leg pain (VAS-LP). There was a statistically significant improvement in all outcome measures (p < 0.001). The debate around which procedure is the most effective for these patients remains controversial.

Our results show that LI-PLIF is as effective as any other surgical procedure. However, given that it is less invasive, we feel that it should be considered as the preferred option.

Introduction: There is an increasing interest in the concept of motion preservation in cervical disc degeneration surgery. There is still a controversy regarding the effect of posterior placement of the disc on the segmental motion of the treated level.

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.

Material and Methods: We retrospectively reviewed 186 prosthesis implanted in 130 patients who underwent an LP Prestige cervical disc replacement and decompression. The distance between the posterior edge of the lower plate of the LP Prestige disc and the posterior wall of the corresponding vertebra was measured. The measurement was performed on a digitalized lateral view x-rays. The posterior placement measurement was correlated to the range of motion of the device on the same level and also on the level above and bellow.

Results: The average age was 46.7 years (range 33–66). The mean posterior placement was 2.96 mm (range 0–6 mm). Range of motion (full flexion to full extension) of the prosthesis was 9.41 degrees (range 0.2–22). Average followup was 2.3 years.

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.

Conclusion: We conclude from our study that there is no correlation between the posterior placement of the Prestige LP and the segmental motion of the prosthesis and the level above and bellow.

Introduction: Cervical disc replacement has emerged as an alternative to the gold standard ACDF in ordered to preserve the motion of the cervical spine, and reduce the risk of adjacent degenerative changes. However, little data actually exists to support or refute the effect of symptoms chronicity on TDA for the treatment of degenerative cervical spine.

Material and Methods: We prospectively investigated 130 consecutive patients who have undergone a Prestige LP cervical disc replacement for degenerative disease causing chronic neck pain and radiculopathy.

The pre and post-operative NDI, SF-36, Visual Analogue Score (VAS), HDS and HAS were recorded.

Results: There were 130 patients in total. There were 66 males and 64 females, with an mean age at surgery was 51.12 +/− 0.84. Seventy five patients had one level disc replacement, and 56 had 2 levels.

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)

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

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.

Conclusion: Duration of symptoms of more that 24 months was associated with less favorable outcome, that was evident in improvement in NDI, HDS, HAS and VAS arm pain. Patients should be counseled when they present with DOS more than 24 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.
