Introduction

Mode of non-operative management of thoracolumbar spine fracture continues to remain controversial with the most common modality hinging on bracing. TLSO is the device with a relative extension locked position, and many authors suggest they may have a role in the healing process, diminishing the load transferred via the anterior column, limiting segmental motion, and helping in pain control. However, several studies have shown prolonged use of brace may lead to skin breakdown, diminished pulmonary capacity, weakness of paraspinal musculature with no difference in pain and functional outcomes between patients treated with or without brace.

We investigated whether an alternative tension band wire technique will produce greater compression and less displacement at olecranon (elbow) fracture sites compared to a standard figure of eight tension band technique. Olecranon fractures are commonly treated with tension band wiring using stainless steel wire in a figure of eight configuration. However recently published studies have raised doubts over the validity of the tension band concept proving that the standard figure of eight configuration does not provide fracture compression when the elbow is flexed. We propose an alternative tension band technique where the figure of eight is applied in a modified configuration producing greater compression across the fracture.

An artificial elbow joint was simulated using artificial forearm (ulna) and arm (humerus) bones. The design simulated the action of the muscles around the elbow joint to produce flexion and extension. There were two arms to this investigation. (1) Standard tension band wire configuration with stainless steel. (2) Modified tension band wire configuration with stainless steel. The simulated elbow was put through a range of movement and sensors measured the compression at the articular and non-articluar surfaces of the fracture. Measurements were taken for compression with different weights applied to challenge both the techniques of tension band wiring.

Measurements from the non articular surface of the fracture demonstrated greater compression with alternative tension band technique. However it was not statistically significant (ANOVA). Compression at the articular surface of the fracture exhibited statistically significant (p<0.05) greater compression with the alternative technique. Neither technique produced greater compression during flexion of the simulated elbow.

The alternative tension band wiring technique proved superior in providing greater compression over the fracture site.

Patient specific instrumentation (PSI) for elective knee replacements in arthritic knees with severe deformities and in revision scenarios is becoming increasingly popular due to the advantage of restoring the limb axes, improved theatre efficiency and outcomes. Currently available systems use CT scan or MRI for pre-operative templating for design considerations with varied accuracy for sizing of implants.

We prospectively evaluated 200 knees in 188 patients with arthritic knees with deformities requiring serial clinical assessment, radiographs and CT scans for PSI templating for TruMatch knee system (DepuySynthes, Leeds, UK). The common indications included severe arthritic deformities, previous limb fractures and in obese limbs with difficult clinical assessment. Surgical procedure was performed on standard lines with the customised cutting blocks.

The ‘lead up’ time between the implant request and the operating date was 5 weeks on an average. We compared the pre op CT images and the best fit post-operative x- rays. The sizing accuracy for femur and tibia was 98.93 % and 95.75% respectively. All blocks fitted the femur and tibia. There were no bail outs, no cutting block breakage, 1 patient had residual deformity of 20 degrees, and 1 patient had late infection. The length of hospital stay, economic viability in terms of theatre turnover, less operating time, cost of sterilisation in comparison to conventional knee replacement surgery with other factors being unchanged was also assessed.

The projected savings was substantial along with improved geometrical restoration of the knee anatomy. We recommend the use of PSI based on CT scan templating in difficult arthritic knees.

TER is a viable surgical option in patients with advanced RA with painful stiff elbows. We retrospectively analysed 22 TER performed in 21 patients over a 12 year period by a single surgeon, with a mean follow up of 64 months (10–145). Disability of the arm, shoulder and hand (DASH) scores were performed pre-operatively and post-operatively in patients through postal questionnaires. The mean age was 59.1 years (32–78). There were 12 women and 9 men. The mean pre-operative DASH score was 72.3 (45.0–91.7) and post-operatively improved to 46.8 (21.7–94.2). Complications included infection, peri-operative fracture, peri-prosthetic fracture and aseptic loosening. There were 6 revisions performed, 2 for peri-prosthetic fracture, 2 for infection, 1 for intra-operative fracture and 1 for symptomatic aseptic loosening. Four patients had died due to unrelated causes. The 10 year survival rate with symptomatic aseptic loosening as the end point was 93% and revisions for all reasons was 69%. Follow up radiographs (in those without revision) were reviewed and 10 had satisfactory positioning of the prosthesis, 5 had loosening of the humeral or radial component and 1 had inadequate cement mantle but was clinically asymptomatic. TER is a rewarding procedure in with advanced RA. Our results are comparable to other published studies.

Dupuytren's disease is often disabling and traditionally has been managed with various surgical methods, with recurrence rates up to 50 %. Recently clostridial collagenase injection has been licensed for use in the NHS.

We prospectively analysed the results of clostridial collagenase injection in 62 patients with varying degrees of Metacarpo phalangeal (MCP) and Proximal interphalangeal (PIP) joint contractures. There were 48 males and 14 females with an average age of 66 years. The average MCPJ and PIPJ deformities were 33 and 17 degrees respectively. Following the infiltration and subsequent manipulation under local anaesthetic and night splinting for 3 months, patients were followed up at 4 weeks and 6 months. Deformities persisted in 5 patients and later required surgical correction. MCPJ deformities were more amenable for correction than PIPJ and in those with recurrence. The average residual deformity was 7 degrees. Common complications include bruising, swelling, pain not responding to routine analgesia, lymphangitis and skin break in some but none required any additional interventions. 14 patients had completed 6 month follow up and there was no recurrence. Subjective assessment through questionnaires revealed high patient satisfaction rate with early return to work within 1 week in most patients. Patients with previous operations preferred injections over operative correction. Collagenase injections are effective in deformity correction with higher satisfaction rate and low morbidity. Early results are encouraging but long term follow up is required to assess recurrence rates.

We retrospectively analysed a single surgeon series of 22 TER in 21 patients over a 12 year period. The mean age and follow up was 59.1 years and 64 months respectively. DASH scores assessed pre and post op confirmed a significant improvement. Complications included infection, intra-operative fracture, peri-prosthetic fracture and aseptic loosening. 6 revisions were performed for various reasons.4 patients had died due to unrelated causes. The 10 year survival rate with symptomatic aseptic loosening as the end point was 93%. 5 patients had radiological loosening but were clinically asymptomatic. TER is a rewarding procedure in with advanced RA.

Clinical decision-making could be difficult when Magnetic resonance imaging (MRI) is used for the diagnosis of knee injuries. We retrospectively studied 565 knee arthroscopies done between 2002 and 2005, 110 of which had suspected ligamentous injuries, evaluated clinically, with MRI and subsequently by arthroscopy.

The aim of the study was to know the extent of correlation of clinical, MRI features with arthroscopy and whether MRI could be justifiably used to deny an arthroscopy. All patients with a strongly suggestive history were examined in the clinic by experienced orthopaedic surgeons and MRI was requested. Clinical examination was repeated under anaesthesia by the operating surgeon who not necessarily had examined the patient initially. The clinical and arthroscopy findings were recorded systematically. 3 Radiology consultants of varying musculoskeletal experience reported the MRI films. The clinical and MRI findings were compared with arthroscopy for the extent of correlation.

We observed that overall Sensitivity of MRI for meniscal injuries was 73%, being more for medial than lateral and 86% for cruciate ligament injuries. Clinical examination had a sensitivity of 33% and a specificity of 93% for meniscal injuries, sensitivity of 86% and specificity of 100% for cruciate injuries. MRI was not able to demonstrate synovial plicae in 13 knees and chondral defects in 3 knees. 96 Knees, which were normal clinically, were found to have meniscal tears on MRI in 65 and subsequently confirmed by arthroscopy in 39.

We conclude that an accurately performed clinical examination with positive signs alone, will be justified for arthroscopy and a negative MRI will not be a sufficient evidence to deny an arthroscopy. Also the reporting will largely depend on the quality of information provided by the clinician, technical factors and the musculoskeletal experience of the person reporting the films.
