Total wrist replacement

A Marcuzzi, F Colantonio, G Petrella, H Ozben, A Russomando
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...

Human musculoskeletal system must modulate work and power output in response to substantial alterations in mechanical demands associated with different tasks. In water, particularly, upper limb muscles must perform net positive work to replace the energy lost against the dissipative fluid load. Where in the upper limb is work and power developed? Is mechanical output modulated similarly at all joints, or are certain muscle groups favored? For the first time, this study examined how work and power per stroke were 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)...

INTRODUCTION: A simplified and computationally efficient human body finite element model is presented. The model complements the Global Human Body Models Consortium (GHBMC) detailed 50th percentile occupant (M50-O) by providing kinematic and kinetic data with a significantly reduced run time using the same body habitus. METHODS: The simplified occupant model (M50-OS) was developed using the same source geometry as the M50-O. Though some meshed components were preserved, the total element count was reduced by remeshing, homogenizing, or in some cases omitting structures that are explicitly contained in the M50-O...

Arthrodesis of the elbow joint addresses pain due to intra-articular pathology, but with significant functional limitations. Loss of motion at the elbow is not completely compensated by the wrist and shoulder joints and elbow fusion is thus purely a salvage procedure. Advances in joint arthroplasty have allowed surgeons to address the functional limitations of arthrodesis, but despite these advances the elbow is still one of the joint replacements with higher complication rate. Conversion of a joint fusion to arthroplasty has been reported for the hip, knee, shoulder, and ankle...

PURPOSE OF THE STUDY: Arthrodesis of the trapeziometacarpal joint is the method of choice in the treatment of degenerative arthritis of this joint. This procedure was indicated most frequently in middle-age patients doing hard manual labor. Methods for achieving a solid fusion of the trapeziometacarpal joint are known and often reported in the literature. Frequently, they are associated with some failure rate, particularly as concerns bone union. Our study presents a simple and effective method verified in cadaver specimens and then currently used at our department...
