chondrotoxicity Chondrocytes were harvested from bovine femoral condyle cartilage
and isolated using collagenase-containing media. At 24 hours after
seeding 15 000 cells per well onto a 96-well plate, chondrocytes
were treated with media (DMEM/F12 + ITS), PBS, 1:1 lidocaine (2%):PBS,
1:1 bupivacaine (0.5%):PBS, 1:1 lidocaine (2%):HA, 1:1 bupivacaine (0.
5%):HA, or 1:1 HA:PBS for one hour. Following treatment, groups
had conditions removed and 24-hour incubation. Cell viability was
assessed using PrestoBlue and confirmed visually using fluorescence

Introduction.
Adductor canal blocks offer an alternative to femoral nerve block for postoperative pain relief in knee arthroplasty. They may reduce the risk of quadriceps weakness, allowing earlier mobilisation of patients postoperatively. However, little is known about the effect of a tourniquet on the distribution of
Background. Total hip replacement (THR) and total knee replacement (TKR) are usually effective at relieving pain; however, 7–23% of patients experience chronic post-surgical pain. These trials aimed to investigate the effect of
Background. The Arthroplasty Pain Experience (APEX) studies are two randomised controlled trials in primary total hip (THR) and knee replacement (TKR) at a large UK orthopaedics centre. APEX investigated the effect of

An isolated avulsion fracture of the peroneus longus tendon is seldom seen and potentially can go undiagnosed using basic imaging methods during an initial emergency visit. If not managed appropriately it can lead to chronic pain, a reduced range of motions and eventually affect mobility. This article brings to light the effectiveness of managing such injuries conservatively. A 55 year old postman presented to clinic with pain over the instep of his right foot for 2 months with no history of trauma. Clinically the pain was confined to the right first metatarsophalangeal joint with occasional radiation to the calf. X-ray films did not detect any obvious bony injury. MR imaging revealed an ununited avulsion fracture of the base of the 1st metatarsal. The patient was subsequently injected with a mix of steroid and

Post-operative pain is well recognised in patients undergoing shoulder surgery. With the recent advances in arthroscopic shoulder surgery over the last decade, a larger number of cases are being performed in day surgery units. These procedures are generally performed under general anaesthetic with either an interscalene or suprascapular nerve block or
More than half of patients with neck of femur (NOF) fractures report their pain as severe to very severe in the first 24hrs. Opioids remain the most commonly used analgesia and are effective for static pain but not dynamic pain. Opioids provide suboptimal analgesia when patients are in a dynamic transition state and their side-effects are a source of morbidity in these patients. The Fascia Iliaca Compartment Block (FICB) involves infiltration of the fascia iliaca compartment with a large volume of low concentrated
Background and Aims. Transforaminal epidurals (TFEs) have been widely used as a treatment for lumbar radicular pain since its introduction by Krempen and Smith in 1974. 1. Originally used as a diagnostic tool, it is now becoming increasingly recognised as a definitive treatment. 2. This study investigates the use of TFEs by a single surgeon over 4 years. We hoped that the study would add to our understanding and the discussion of the actual benefit of therapeutic steroid and
In 2012 collagenase Clostridium histolyticum (Xiapex) was approved by the SMC for restricted use for the treatment of Dupuytren's contracture. Xiapex was approved on a case by case basis for patients with a palpable pretendinous cord, giving rise to MCPJ contracture of greater than 30 degrees. As of September 2012 we began to offer Xiapex injections to patients in Ayrshire who enquired about the injection, and met the SMC criteria. To date injections have been performed on 3 patients, in a total of 7 digits. Patients were assessed prior to injection and manipulation, with the degree of contracture recorded and DASH scores noted. Each patient then underwent a standard injection of 0.58 mg of Xiapex. 48 hours post injection each patient underwent manipulation under
Single shot interscalene blocks are an effective analgesic for arthroscopic shoulder surgery. However, patients receiving these blocks are often found to be in significant pain when the block wears off, usually in the late evening or early hours of the morning. Overnight admission is currently routine in our unit, to ensure adequate analgesia can be administered during this period. Recent studies have suggested that adding dexamethasone to the
The Cochrane Collaboration has produced five new reviews relevant to bone and joint surgery since the publication of the last Cochrane Corner These reviews are relevant to a wide range of musculoskeletal specialists, and include reviews in Morton’s neuroma, scoliosis, vertebral fractures, carpal tunnel syndrome, and lower limb arthroplasty.
