Objective: To assess the temporal geometric sagittal profile changes on serial radiographs of fractures of the thoracic and thoraco-lumbar spine.

Materials and methods: We have included 103 patients with thoracic or lumbar fractures were treated at our unit between June 2003 and May 2006. The patients were suitable for non-operative treatment. The mean age of the cohort was 46.9±2.4 (16–90). The sex distribution was equal. 94 patients had a single level lesion. 19 fractures were in the thoracic spine; 64 in the thoraco-lumbar (T11-L1) and 29 between L2 and L5. The radiographs were scored using the AO classification by 2 senior orthopaedic trainees. The radiographs were analysed at the Spine Research Laboratory. The results were computed using Stat, a statistical software.

Results: The changes were assessed over a mean period of 5.6 mo (range 1–49 mo; 95% CI 4.1–7.1 mo). Weighted kappa score of 0.58 was computed for the primary fracture type and 0.22 for the fracture sub-types. The inter-observer rater agreement was similar to that reported in literature. 7 patients showed a significant collapse. We report the association between the fracture types and the extent of collapse. We have also assessed the association between the medium to long term symptoms, the fracture types and the extent of collapse at the fracture sites and the adjacent disc.

Conclusion: Some fracture sub-types are more likely to collapse and cause long term symptoms. Identifying these fractures at the outset would help clarify surgical indications.

Aim: Retrospective review of patients after coccygectomy for post traumatic coccydynia.

Methods: 13 patients (2 male, 11 female; mean age 37.8 years) who had undergone coccygectomy in our unit between 1995–2005 were identified and their case notes were reviewed. All patients had coccydynia with clear history of trauma, had failed to respond to three MUA and injections, and on clinical examination by senior author had hypermobile coccyx.

All patients were operated by the senior author, using a standard technique whereby all segments of the coccyx from sacrococcygeal joint were excised. At follow up postal questionnaire was sent to all patients. This included, Visual Analogue Score (VAS) for Pain now and VAS for pain over one week, overall patient satisfaction, and Oswestry disability Index (ODI), The non-respondents were contacted by telephone 3 weeks later. Overall response was 100%.

RESULTS: Mean time from the onset of symptoms to coccygectomy was 23.8 months (range 5–72). Average length of follow up was 3.8 years (range 0.7–10.8).

6 patients (46%) had 0 pain for VAS now and VAS over one week. 2 patients (15%) had mild pain VAS (1,2) for pain now and over 1 week, and 4 patients(31%) had moderate pain VAS (5,5,5,6) for pain now and VAS (5,5,5,5) for pain over 1 week and 1 patient (8%) had severe pain VAS (8).

ODI was normal or mild disability (0–20%) in 8 patients (71%), 4 patients had moderate disability (ODI 21–40%) and 1 had sever disability (ODI 54%).

Overall Ten patients (76.9%) were satisfied with the result and would consider the same surgery again.

Conclusion: Surgical treatment of post traumatic coccydynia resistant to conservative measures can lead to satisfactory results, if appropriate patient selection criteria are applied.

Type of study: Case-series comparison.

Patients: 20 patients (2 males); average age 15.5 years; mean follow-up 22 months. 10 patients (Lenke type 1) had anterior correction and instrumentation; 10 patients (Lenke type 2) had posterior operations. All patients had a selective thoracic fusion (with the type 2 curves having instrumentation incorporating the proximal thoracic curve).

Outcome measures: Complications, radiological parameters (Cobb correction of major & compensatory curves); trunk shape (rib hump / scoliometer), and SRS-22 questionnaires.

SRS-22 outcomes: There was no significant difference in the pre-operative individual domain scores (pain, self-image, function, mental health, satisfaction) between the two groups. There were no differences in the postoperative results (including self-image) apart from pain. The anterior surgery group had more persistent pain, but at a similar level than preoperatively (3.2 [0.8] vs 4.6 [0.3], p~0.03).

Conclusion: For right thoracic (Lenke curve types 1& 2) late-onset idiopathic scoliosis both types of surgery deliver similar radiological and trunk-shape results. SRS-22 self-image and function post-operative results are also similar. The anterior procedure did not however improve the pre-operative pain score.

In a prospective study to evaluate the benefits of radial extracorporeal shockwave therapy (ESWT) in patients with longstanding chronic Achilles tendonitis. 34 cases of non-insertional Achilles tendonitis were treated in 32 patients, using radial shockwave treatment. Symptoms had been present for at least ten months and were resistant to conservative treatments. Patients received three shockwave sessions at weekly intervals. Evaluation was performed prior to treatment, at six weeks and three months after the final session. Patients completed a visual analogue score (VAS) for maximal pain (0–100), the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot Scale and the Victorian Institute of Sport Assessment-Achilles questionnaire (VISA-A).

At short-term review all patients reported an improvement in symptoms. The VAS fell from a pre-treatment value of 74 (+/−15) to 22 (+/−17). An improvement in the AOFAS from of 64 (+/−10) to a post-treatment value of 90(+/−7) was seen, and an average from 30 to 70 in the VISA-A score. No complications from the treatment were reported. Four patients previously listed for surgery have improved sufficiently to be removed from the waiting list.

Conclusion: Short-term results using ESWT for the treatment of longstanding non-insertional Achilles tendonitis are encouraging. Longer-term follow-up subsequent to this prospective pilot study is underway to assess if results are reproducible over a greater time period.

Aims: Limb sparing surgery, for selected cases of long bone primary malignancy, may be accomplished with the use of large prostheses. Conventional joint implants are known to release metal ions by corrosion or wear. The aim of this study was to determine if a specialist group of patients had elevated serum metal levels. Methods: Over a 12 month period, 20 patients who had undergone previous surgery were recruited from a bone tumour clinic. A 10ml venous blood sample was obtained and analysed for trace metals using a previously published mass-spectrometry technique. Results: Eight children (mean age 14.5 years) and 12 adults (mean age 46.5 years) were recruited a mean of 54 months and 86 months following surgery, respectively. Trace metal (aluminium, titanium, cobalt) elevation was observed in 5/8 (63%) paediatric cases and 6/12 (50%) adult cases. Three of the adults had signiþcantly raised levels, (≤ 50 times), and had undergone revision surgery for loosening. There was no observed implant loosening in the paediatric group. Conclusions: This small sample has demonstrated that many patients with long-term large tumour implants have trace metal levels below laboratory detection. Signiþcant elevation of metal levels in adults was associated with loosening or wear of implants. A signiþcant proportion of paediatric cases had slight elevations, but the signiþcance of this is unknown at present.
