BACKGROUND: Thorough debridement is mandatory in revision for infected total knee arthroplasties (TKA). We investigated a novel adjuvant chemical debridement strategy using acetic acid (AA) that seeks to create a hostile environment for microorganisms. We report the first orthopedic in vivo series using an AA soak in infected TKAs. We also investigated the in vitro efficacy of AA against bacteria isolated from these knees. METHODS: Twenty-three patients with infected TKA were treated with a standard debridement protocol and chemical debridement with a 20-minute AA soak...

This work deals with the mechanical characterization by depth-sensing indentation (DSI) of PLLA and PLDA composites reinforced with micro-particles of Mg (up to 15wt%), which is a challenging task since the indented volume must provide information of the bulk composite, i.e. contain enough reinforcement particles. The composites were fabricated by combining hot extrusion and compression moulding. Physico-chemical characterization by TGA and DSC indicates that Mg anticipates the thermal degradation of the polymers but does not compromise their stability during processing...

Skin temperature may help prospectively determine whether an area of skin discoloration will evolve into necrosis. A prospective, observational study was conducted in 7 skilled nursing facilities to determine if skin temperature measured using infrared thermography could predict the progression of discolored intact skin (blanchable erythema, Stage 1 pressure ulcer, or sus- pected deep tissue injury [sDTI]) to necrosis and to evaluate if nurses could effectively integrate thermography into the clinical setting...

OBJECTIVE: The number of studies investigating correlations between the temporomandibular system and body posture, postural control or plantar pressure distribution is continuously increasing. If a connection can be found, it is often of minor influence or for only a single parameter. However, small subject groups are critical. This study was conducted to define correlations between dental parameters, postural control and plantar pressure distribution in healthy males. METHODS: In this study, 87 male subjects with an average age of 25...

BACKGROUND: Cervical spondylotic myelopathy (CSM) is a common disease of aging that leads to gait instability resulting from loss of leg sensory and motor functions. The results of surgical intervention have been studied using a variety of methods, but no test has been reported that objectively measures integrative leg motor sensory functions in CSM patients. OBJECTIVE: To determine the feasibility of using a novel single leg squat (SLS) test to measure integrative motor sensory functions in patients with CSM before and after surgery...

BACKGROUND: Appropriate assessment and interventions for breathing patterns prior to assessment of the patient's musculoskeletal complaint may be beneficial. Breathing pattern disorders (BPDs) are remediable and influenced by biochemical, biomechanical, psychological, and/or unknown factors. The purpose of this clinical commentary is to demonstrate the integratration of a BPD assessment into a standard clinical musculoskeletal orthopedic examination. CLINICAL ASSESSMENT: The observation of a patient's breathing pattern begins when they enter the clinic, is followed by palpation and orthopedic tests, which allows for proper classification of BPDs...

We present a patient with congenital spinal muscular atrophy associated with pain, subjective sensory loss, right talipes equinovarus, delayed walking, and progressive gait impairment. A sister and niece reportedly had Charcot-Marie-Tooth 1A, but the patient's electromyogram showed an axonal motor neuropathy or neuronopathy. We identified a c.806G>A TRPV4 gene mutation causing an Arg269His amino acid substitution. TRPV4 mutations cause variable phenotypes including axonal sensorimotor neuropathy and motor neuropathy or neuronopathy...

BACKGROUND: Psychological inflexibility-the inability to take value-based actions in the presence of unwanted thoughts, feelings, or bodily symptoms-is associated with negative health outcomes including depression and anxiety. OBJECTIVE: We aimed to determine the association between the general construct of psychological inflexibility and pain intensity, and upper extremity physical function in patients with musculoskeletal illness in an orthopedics practice. We also set out to test multiple-mediator models proposing that psychological inflexibility affects pain intensity and upper extremity physical function directly, as well as indirectly through depression, anxiety, and pain catastrophizing...

Orthopedic dogma states that external fixator stiffness is improved by placing 1 pin close to the fracture and 1 as distant as possible ("near-far"). This fixator construct is thought to be less expensive than placing pins a shorter distance apart and using "pin-bar" clamps that attach pins to outriggers. The authors therefore hypothesized that the near-far construct is stiffer and less expensive. They compared mechanical stiffness and costs of near-far and pin-bar constructs commonly used for temporary external fixation of femoral shaft fractures...
