Introduction. Fusion represents an effective treatment option in patients affected by end-stage arthritis. To minimise the risk of non-union following fusion, biological preparations such as bone marrow aspirate concentrate (BMAC) are commonly used intra-operatively. Mechanotransduction represents an emerging field of research whereby physical stimuli can be used to modulate the behaviour and differentiation of cells. Blast waves (a subtype of shock waves) are one such physical stimulus. The aim of this study was to investigate whether the osteogenic potential of BMAC can be enhanced using a blast wave, and thus improve its efficacy in fusion surgery. Methods. Human BMAC samples were obtained from three healthy patients and exposed to a single blast wave (peak overpressure= 50psi), before being placed in a suspension of mesenchymal stem cells, to represent the biological environment of the fusion site. Three test groups were used: MSC (the experimental control); MSC + BMAC; MSC + BMAC + blast wave. Calcium mineralisation assays were performed on the MSCs on Day 7 and 14 to assess for osteoblastic transformation. Results. Calcium mineralisation on Day 7 was significantly increased in the MSC + BMAC group compared to the MSC group (mean percentage change 42.12 vs 0.0, p=0.012). The MSC + BMAC + blast wave group also demonstrated significantly increased levels compared to the MSC + BMAC group (84.56 vs. 42.14, p = 0.039). The difference in calcium mineralisation between the MSC and MSC + BMAC + blast wave groups was strongly significant (0.00 vs. 84.56, p = 0.003). Conclusion. Exposure of BMAC to a single blast wave enhances its osteogenic potential. This represents a potential novel way to improve healing following fusion surgery and reduce the rates of non-union

It has been suggested that extracorporeal shockwave therapy is a safe and effective treatment for pain relief from recalcitrant plantar fasciopathy (PF). However, the changes in gait and associated biomechanical parameters have not been well characterised. We recruited 12 female patients with recalcitrant PF who had a mean age of 59 years (50 to 70) and mean body mass index of 25 kg/m. 2. (22 to 30). The patients reported a mean duration of symptoms of 9.3 months (6 to 15). Shockwave therapy consisting of 1500 impulses (energy flux density 0.26 mJ/mm. 2. ) was applied for three sessions, each three weeks apart. A pain visual analogue scale (VAS) rating, plantar pressure assessment and motion analysis were carried out before and nine weeks after first shock wave therapy. It was demonstrated that patients increased their walking velocity and cadence as well indicating a decrease in pain after shockwave therapy. In the symptomatic foot, the peak contact pressure over the forefoot increased and the contact area over the digits decreased. The total foot impulse also decreased as did stance duration. The duration the centre of pressure remained in the hindfoot increased in the symptomatic foot after shockwave therapy. The differences in centre of pressure trajectory at baseline decreased at final follow-up. In conclusion, shockwave therapy not only decreased the pain VAS rating but also improved the gait parameters of the symptomatic foot in PF patients.

Introduction:. Primary functions of heel and forefoot fat pad - shock absorber at heel strike, energy dissipation, load bearing, grip and insulation. •Reliability of weight bearing heel pad thickness measurements by ultrasound has been determined by Rome et al. Importance of soft tissue fillers has been recently popularised by Coleman. Methods and materials:. Harvesting done by standard low pressure liposuction using small cannula. Grafting using small needle depositing the small globules of fat in multiple layers of soft tissue. There is an expectation that up to 50% of the fat will be lost and so upto 19mls of fat placed per foot. Patients were kept NWB for 4–6 weeks post op and then allowed to mobilise fully. Case notes were prospectively collated and analysed. Pre and post-op ultrasound scans were performed to document the depth of the heel/forefoot fat pad. Clinical pictures were taken and post-op patient satisfaction scores were done as well. Results:. We treated 9 feet in 5 patients. 5 heel fat pad transfers and 4 forefoot. Pain completely relieved in all feet. No complications. Average pre-op VAS - 3/ Post-op – 9. Average pre-op AOFAS score - 70/ post-op - 105. Follow-up 6months - maximum 23 months. Conclusion:. Fat transfer is usually used for cosmetic reasons and occasionally to improve scars. Very few reports from South America have been published for patients using high heels giving pain but none for patients with a pathological anomaly. The technique seems to highly effective with no complications so far. It is currently being used on other painful problems in other areas of the sole with equal success. Abdominal fat transfer is an innovative technique aimed at getting rid of the ‘heel pad syndrome’

Achilles tendinopathy is chronic degeneration of the Achilles tendon, usually secondary to injury or overuse. It involves a triad of pain, swelling and impaired function. Primary treatment is rest, analgesia, corticosteroid injections and physiotherapy (eccentric training and heel pads to correct gait). Some patients remain symptomatic and further treatment options need considering. NICE produced a document from the Interventional Procedures Advisory Committee in 2009 which reviewed the literature and evidence for extracorporeal shockwave treatment (ESWT). Low energy shock wave treatment (SWT) is thought to stimulate soft tissue healing, inhibit pain receptors and promote angiogenesis. NICE guidance was that ESWT could be used in refractory Achilles tendinopathy if used for clinical governance, audit or research. Patients with refractory Achilles tendinopathy were enrolled between October 2010 and 2011. They received three sessions of ESWT over three week. Patients completed visual analogue scale (VAS) scores for pain at rest and on activity and the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire pre-treatment. These outcome measures and a six-point Likert satisfaction scale (six points, high is worsening) were reassessed at 6 and 16 weeks post treatment. 51 patients completed follow up. The mean age was 56 (34–80) years and mean length of symptoms 34 (4–252) months. There was a significant improvement (p<0.05) in VAS scores observed from baseline and 16 weeks post treatment. This was also the case in the VISA-A scores. The mean Likert score was 3 (somewhat improved) at 16 weeks but there was no statistical significance. This study suggests that ESWT improves subjective and objective outcomes in patients with refractory Achilles tendinopathy. Patients over 60 possibly have a worse outcome along with patient who had symptoms for over 25 months. Follow up scores at one year are due to be collected and the data will be submitted to NICE

Heel pain is very prevalent. Pain, especially after a period of rest, is the main symptom. Reduced ability to walk long distances and inability to participate in exercise and sport are other complaints. Plantar heel pain is most commonly caused by plantar fasciitis. Whilst only the recalcitrant cases reach secondary care, this can still be a significant workload. In the Royal Surrey County Hospital, Guildford, we see approximately 200 cases of recalcitrant heel pain each year. The vast majority of cases never come to hospital and are managed in primary care (1500/yr in podiatry alone). Effective primary treatments should reduce the number of long-term sufferers. Recalcitrant cases of plantar fasciitis often have atypical symptoms. Radiological imaging is extremely useful in clarifying the diagnosis. Ultrasound is our preferred modality. There is a spectrum of pathology that affects the plantar fascia, and this is less well classified than for the achilles tendon, where the distinction between insertional tendinopathy and tendinopathy of the main body of the tendon is helpful in guiding treatment. The evidence for many forms of treatment for plantar fasciitis is weak. Currently, the use of formal calf stretching programs is widely considered to be the best first-line treatment. There are additional benefits with stretches to the fascia itself. The mechanism by which these stretches help is not well established. Calf contracture is, however, associated with a variety of clinical problems in the foot and ankle. This is especially true for isolated gastrocnemius contracture. There is also laboratory evidence that increased plantar fascia strain is seen with increased calf muscle tension. Surgery to release a gastrocnemius contracture improves biomechanics and has been used in refractory cases of heel pain with good effect. Radial extracorporeal shock wave lithotripsy is the latest version of this non-invasive treatment. Results in our centre are encouraging. For selected cases of atypical plantar fasciopathy injection treatments are effective

Injuries to the foot in athletes are often subtle and can lead to a substantial loss of function if not diagnosed and treated appropriately. For these injuries in general, even after a diagnosis is made, treatment options are controversial and become even more so in high level athletes where limiting the time away from training and competition is a significant consideration.

In this review, we cover some of the common and important sporting injuries affecting the foot including updates on their management and outcomes.

We present a series of 16 patients treated between 1993 and 2006 who had a failed total ankle replacement converted to an arthrodesis using bone grafting with internal fixation. We used tricortical autograft from the iliac crest to preserve the height of the ankle, the malleoli and the subtalar joint. A successful arthrodesis was achieved at a mean of three months (1.5 to 4.5) in all patients except one, with rheumatoid arthritis and severe bone loss, who developed a nonunion and required further fixation with an intramedullary nail at one year after surgery, before obtaining satisfactory fusion. The post-operative American Orthopaedic Foot and Ankle Society score improved to a mean of 70 (41 to 87) with good patient satisfaction. From this series and an extensive review of the literature we have found that rates of fusion after failed total ankle replacement in patients with degenerative arthritis are high. We recommend our method of arthrodesis in this group of patients. A higher rate of nonunion is associated with rheumatoid arthritis which should be treated differently.
