OBJECTIVES: Mesenchymal stem cells (MSCs) are frequently delivered via needle injection for treatment of musculoskeletal injuries. The purpose of this study was to evaluate the effect of needle diameter on the viability of MSCs. METHODS: Equine bone marrow-derived MSCs from 5 horses were suspended in PBS, and held at room temperature for 7 hours to mimic shipping conditions. Two replicate samples for each needle size (20, 22, 23, or 25-gauge [ga]) were aspirated into a 3 mL syringe and re-injected into the holding vial 3 times, to reproduce the resuspension of cells prior to injection in clinical cases...

BACKGROUND: The rheumatologist relies heavily on clinical skills to diagnose diverse conditions, something that is correlated with one's knowledge of clinical anatomy. More recently, rheumatology has offered further career flexibility with opportunities to develop skills such as joint injection and musculoskeletal (MSK) ultrasound, both of which require a sound understanding of anatomy. Currently, there are no formal strategies to support competency-based anatomy learning in rheumatology in the UK...

Adipose-derived mesenchymal stem cells (AMSCs) offer potential as a therapeutic option for clinical applications in musculoskeletal regenerative medicine because of their immunomodulatory functions and capacity for trilineage differentiation. In preparation for a phase I clinical trial using AMSCs to treat patients with osteoarthritis, we carried out preclinical studies to assess the safety of human AMSCs within the intra-articular joint space. Culture-expanded human AMSCs grown in human platelet-lysate were delivered via intra-articular injections into normal healthy rabbit knees and knees at risk for the development of osteoarthritis after bilateral medial anterior hemimeniscectomy...

OBJECTIVES: To provide musculoskeletal ultrasound (MSKUS) images of hand anatomy in the position of hemiparetic flexion as a reference for spasticity injections. After a stroke, spasticity can result in anatomic distortion of the hand. Spasticity may require treatment with botulinum toxin or phenol injections. Anatomic distortion may decrease the accuracy of injections. Standard anatomic references are of limited utility because they are not in this spastic hemiparetic position. There presently is no anatomic reference in the literature for these spastic postures...

OBJECTIVE: Ischemia-reperfusion (IR) is a limb- and life-threatening complication of acute limb ischemia and musculoskeletal trauma. Carbon monoxide-releasing molecules (CORMs) have recently been shown to protect microvascular perfusion and to reduce inflammation and injury in various ischemic animal models. The purpose of this study was to examine the effects of water-soluble CORM-3 on the extent of IR-induced muscle injury. METHODS: Wistar rats were randomized into three groups: sham (no ischemia), IR + CORM-3 (10 mg/kg intraperitoneally), and IR + inactive CORM-3 (iCORM-3; 10 mg/kg intraperitoneally)...

Whereas much is known regarding the musculoskeletal responses to full unloading, little is known about the physiological effects and response to pharmacological agents in partial unloading (e.g. Moon and Mars) environments. To address this, we used a previously developed ground-based model of partial weight-bearing (PWB) that allows chronic exposure to reduced weight-bearing in mice to determine the effects of murine sclerostin antibody (SclAbII) on bone microstructure and strength across different levels of mechanical unloading...

Chronic widespread musculoskeletal pain is a cardinal symptom in hypermobility type of Ehler Danlos Syndrome (EDS type III). The management of pain in EDS, however, has not been studied in depth. A 30 year old female, known case of EDS, presented to the pain clinic with complaints of severe upper back pain for 6 months. Physical examination of the back revealed two myofascial trigger points over the left rhomboids and the left erector spinae. Local anaesthetic trigger point injections were given at these points, followed by stretching exercises under analgesic cover for the first week...

BACKGROUND: Local drug delivery devices offer a promising method for delivering vancomycin and amikacin for musculoskeletal wounds. However, current local delivery devices such as beads and sponges do not necessarily allow for full coverage of a wound surface with eluted antibiotics and do not address the need for reducing the antibiotic diffusion distance to help prevent contamination by bacteria or other microorganisms. We blended chitosan/polyethylene glycol (PEG) pastes/sponges to increase biocompatibility and improve antibiotic coverage within the wound...

OBJECTIVE: Acute hematogenous infection is a devastating complication that can occur after total knee arthroplasty (TKA). The best strategies for management of this infection remain controversial. Two-stage revision has been well described as the gold standard for the management of chronic late infections. However, there is a paucity of information presently available on the management and outcomes of patients treated for acute hematogenous infections. The purpose of the present study was to report the outcome of acute hematogenous infections following TKA with the treatment of irrigation, debridement, and retention of the prosthetic components...

SETTING: Interventional procedures directed toward sources of pain in the axial and appendicular musculoskeletal system are performed with increasing frequency. Despite the presence of evidence-based guidelines for such procedures, there are wide variations in practice. Case reports of serious complications such as spinal cord infarction or infection from spine injections lack appropriate context and create a misleading view of the risks of appropriately performed interventional pain procedures...

Botulinum toxin (BTX) is used for multiple clinical indications due to its ability to induce temporary chemodenervation and muscle paralysis. This property has supported its application in treating a variety of musculoskeletal conditions, especially those involving muscular hyperactivity and contractures such as cerebral palsy and dystonia. However, off-label use of BTX injection in other musculoskeletal disorders is gaining increased acceptance, such as in neurogenic thoracic outlet syndrome, epicondylitis, and shoulder pain after stroke...

Véronique Freire, Nathalie J Bureau
Corticosteroids are routinely injected into soft tissues, tendon sheaths, bursae, and joints. These anti-inflammatory agents have different potency and solubility, and solubility is inversely correlated with the duration of action. Corticosteroids carry a low risk of complications but commonly cause systemic and local adverse effects. The use of intra-articular corticosteroid injections in the treatment of inflammatory arthritis and osteoarthritis is well established. Evidence also supports the use of injectable corticosteroids in the treatment of inflammatory tenosynovitis and bursitis associated with rheumatic diseases, trigger finger and de Quervain disease, and carpal tunnel syndrome...
