This paper presents a wearable microsystem for minimally invasive, autonomous, and pseudo-continuous blood glucose monitoring, addressing a growing demand for replacing tedious fingerpricking tests for diabetic patients. Unlike prevalent solutions which estimate blood glucose levels from interstitial fluids or tears, our design extracts a whole blood sample from a small lanced skin wound using a novel shape memory alloy (SMA)-based microactuator and directly measures the blood glucose level from the sample...

Kienböck disease is an aseptic osteonecrosis of the lunate, which gradually leads to total carpal collapse. Lichtman's classification relates radiographic evidence of wrist damage to four different stages and supports surgical decision-making. This study pertains to six patients (2 males and 4 females) affected by stage IV Kienböck's disease who underwent proximal row carpectomy and received an RCPI implant. The clinical outcomes consisted of wrist range of motion (ROM), pain on a VAS scale (0-10), the DASH score and the patient's level of satisfaction...

The human musculoskeletal system must modulate work and power output in response to substantial alterations in mechanical demands associated with different tasks. In particular, in water, upper limb muscles must perform net positive work to replace the energy lost against the dissipative fluid load. Where in the upper limb are work and power developed? Is mechanical output modulated similarly at all joints, or are certain muscle groups favored? This study examined, for the first time, how work and power per stroke are distributed at the upper limb joints in seven male participants sculling while ballasted with 4, 6, 8, 10 and 12 kg...

The use of implant arthroplasty in the hand and wrist is increasing, often with little evidence of outcomes in the literature. We therefore undertook a systematic review of the outcomes of distal radio-ulnar joint arthroplasties following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Papers were assessed for outcomes, implant survival and methodological quality. Fourteen papers assessed ulna head replacements. The implant survival rate was 93% at a mean follow-up of 45 months...

BACKGROUND: The purpose of this study was to evaluate a potential risk of intraoperative contamination associated with clothing systems and surgeon's motion in total joint replacement. METHODS: The airborne particle concentrations at different locations around a single operating surgeon wearing standard surgical gown (SG) or modern "space suit" (SS) were compared. The particles in the size of ≥0.5 μm (roughly corresponding to a mean diameter of squamous epithelial cells) were counted at the following three locations: (1) ≈10 cm inferior to the wrist; (2) ≈10 cm posterior to the feet; and (3) near the chest (operative field) under condition either with or without the surgeon's motion (stepping in place at ~1 Hz)...

BACKGROUND: Growth can be one of the most uncertain variations, but understanding the same is very important for diagnosis and treatment planning. Skeletal age and dental age have been used to determine a child's developmental age. Several researchers have evaluated the association between dental and skeletal maturity with chronologic age on different population. The purpose of the present study was to find out whether dental age estimation can be replaced for skeletal age estimation in the Dakshina Kannada population...

Background The elbow joint is a complex compound articulation, with a linking role within the upper limb kinematics. Its hinge function allows for proper placement of our working instrument (the hand) in the space surrounding us, directed by the shoulder joint. Both reliable mobility and stability are essential elements to allow for consistent bridging of the distance we aim to achieve in common daily activities. Sufficient flexion and extension are required to ensure both the patients' independence and the dignity...

Total wrist arthroplasty are not used as widely as total knee and hip replacement. The functional hands are requiring surgeons to design a durable and functional satisfying prosthesis. This article will list the main reasons that cause the failure of the prosthesis. Some remarkable and representative prostheses are listed to show the devolvement of total wrist prosthesis and their individual special innovations to fix the problems. And the second part we will discuss the part that biomechanical elements act in the total wrist replacement (TWA)...
