Resumo:

Background: There is poor consensus in the literature regarding associated functional limitation and the preferred wrist position for total wrist arthrodesis. The purpose of the current investigation was twofold: (1) to assess the functional limitations of wrist arthrodesis and (2) to determine the optimal position for wrist arthrodesis using a simulated wrist fusion model. Methods: Twenty healthy volunteers underwent simulated wrist arthrodesis in 6 different positions using custom-molded wrist splints: 15° extension with 0° radio-ulnar deviation, 15° extension with 10° ulnar deviation, 15° extension with 10° radial deviation, 0° extension with 0° radio-ulnar deviation, 0° extension with 10° ulnar deviation, and 0° extension with 10° radial deviation. Each volunteer was independently assessed for wrist function using the Jebsen-Taylor hand function test, grip strength, and satisfaction in the simulated wrist fusion positions. Comparisons between all simulated fusion wrists and the baseline unsplinted wrist as well as among the 6 simulated fusion positions were performed. Results: Turning over a card (5.1 vs 4.3 seconds), picking up small objects (7.1 vs 5.8 seconds), and simulated feeding (8.3 vs 7.1 seconds) as well as total Jebsen-Taylor test duration (41.8 vs 37.9 seconds) was significantly longer in simulated fusion wrists. Both grip strength (55.9 vs 80.7 kg) and satisfaction scores (6.4 vs 9.6) were lower in simulated fusion wrists. Wrists in 0° extension also demonstrated significantly shorter durations in stacking checkers than wrists in 15° extension. Conclusion: Our findings suggest that wrist arthrodesis may only compromise select wrist functions. Among the tested wrist fusion positions, wrists fused in neutral may demonstrate better function than wrist fused in slight extension. However, grip strength and satisfaction seem to be unaffected by wrist fusion position.

A retrospective study compared outcomes of total wrist arthrodesis as a salvage for total wrist arthroplasty versus primary total wrist arthrodesis. Seventy-one wrists were reviewed after a minimum follow-up of 12 months. Thirty-two wrists with failed total wrist arthroplasty were converted to a wrist arthrodesis and 39 wrists received a primary wrist arthrodesis. Seven converted wrist arthrodeses and five primary arthrodeses failed to fuse. Mean patient-rated wrist and hand evaluation scores and work-related questionnaire for upper extremity disorders scores were 43 and 39 for converted total wrist arthrodesis and 38 and 33 for the primary total wrist arthrodesis. Overall, there were 25 complications in 15 patients in the converted wrist arthrodesis group and 21 complications in 16 patients after a primary wrist arthrodesis. The results between the two groups were slightly in favour of patients with a primary wrist arthrodesis. Therefore, we conclude that the timing, primary or conversion, of total wrist arthrodesis could influence patient outcomes. Level of evidence: III

Salvage of failed total wrist arthroplasty by arthrodesis may be difficult because of bone loss and poor quality of bone and soft tissues. We examined the outcomes of wrist arthrodesis for failed total wrist arthroplasty in a retrospective study of 21 wrists in 17 patients. Clinical data, radiographs, patient-reported outcomes and DASH questionnaires were used. Thirteen women and four men had undergone total wrist arthroplasty at an average age of 55 years. The mode of failure was aseptic loosening in 13 wrists. The average time from the index arthroplasty to wrist arthrodesis was 7.6 years. Autograft and/or allograft bone graft was used in all of the wrists. Arthrodesis was achieved in 11 wrists and ten had a nonunion. Six arthrodeses underwent eight revisions for nonunion, with two achieving union. The mean DASH score was 29 in wrists that fused and 36 in those that did not fuse. Pain scores averaged 2.1 in the wrists that fused and 3.3 in the nonunion group. Most patients had clinical improvement.

In 1966, Wilhelm published a technique of denervation of the wrist joint based on his own anatomical studies of 1958. Other authors have published their experience in wrist denervations with similar results, but there are some discrepancies in descriptions of the innervation of the wrist. We have studied the innervation of the wrist by dissection under magnification on 20 cadaver limbs and by histological examination of five human foetal wrists. Based in our anatomical findings, we have demonstrated that Wilhelm's technique does not achieve total denervation of the wrist.

Dorsal wrist pain with or without a palpable dorsal wrist ganglion is a common complaint. Watson developed the concept of the dorsal wrist syndrome (DWS) which is an entity encompassing pre-dynamic rotary subluxation of the scaphoid and the overloaded wrist. We reviewed 20 cases of DWS treated surgically. There were nine males (11 wrists) and nine females (nine wrists). Post-operative follow-up ranged from five to 67 months (mean, 37 months). At operation, we observed SLL tears in eight wrists and dorsal ganglia in 12 cases. Following surgery, 12 cases reported being pain free, five had mild pain, two moderate pain and one case reported severe pain. Post-operative extension/flexion was 73/70 average. Post-operative grip strength was 28 kg average. We believe that excision of the posterior interosseous nerve and the dorsal capsule including the ganglion, if present, provides pain relief in DWS.

This paper treats the three-jointed spherical wrist on which the tool is placed at an angle δ ≠ 0. A two-parameter set of axes is identified for the wrist such that the angular velocities and accelerations at the three joints are within acceptable limits during a 2π-rotation of the end-effector at constant speed about each such axis. This set of axes is compared both to the total set of available axes of full rotation and to the set for which the determinant of the wrist Jacobian is greater than a specified minimum value. For each set of axes, hypothetical substitute-wrists permit the generalization of design conditions for robots with spherical wrists on which δ = 0 to robots with spherical wrists on which δ ≠ 0, and they provide geometrical limits on tool-placement which bound the velocities and accelerations at the wrist joints. Lastly, comments are made about balancing the velocity and acceleration characteristics of the actuators in a spherical wrist.

The purpose was to determine if smartphone photography is a reliable tool in measuring wrist movement. Smartphones were used to take digital photos of both wrists in 32 normal participants (64 wrists) at extremes of wrist motion. The smartphone measurements were compared with clinical goniometry measurements. There was a very high correlation between the clinical goniometry and smartphone measurements, as the concordance coefficients were high for radial deviation, ulnar deviation, wrist extension and wrist flexion. The Pearson coefficients also demonstrated the high precision of the smartphone measurements. The Bland–Altman plots demonstrated 29–31 of 32 smartphone measurements were within the 95% confidence interval of the clinical measurements for all positions of the wrists. There was high reliability between the photography taken by the volunteer and researcher, as well as high inter-observer reliability. Smartphone digital photography is a reliable and accurate tool for measuring wrist range of motion. Level of evidence: II

The Universal 2 total wrist arthroplasty is intended to alleviate wrist pain and restore function. There is limited evidence regarding its success and safety. We report outcomes in 48 wrists of 46 patients with Universal 2 arthroplasty between 2006 and 2014. We recorded range of motion of the operated wrist, patient satisfaction, complication and revision rates, and radiological appearances of the wrists with mean follow-up of 7 years (3.5 to 11 years). We found a significant improvement in DASH scores after surgery, with active range of wrist motion being 33° flexion and 24° extension. Thirty-nine patients would undergo the procedure again if he had similar wrist problems. Twenty-three patients had loosening of at least one component of the implant. Complications were found in 13 wrists; seven underwent revision. We conclude that the Universal 2 arthroplasty produces significant improvements in DASH scores and high levels of satisfaction of the patients. However, the surgery has a high complication rate.

From 2001 to 2015, 11 wrists in 11 patients with osteoarthritis of the wrist had failed wrist arthroplasties, which were subsequently converted to arthrodesis using intercalated corticocancellous autograft from the iliac crest and fixation with an arthrodesis plate or a customized peg. Clinical and radiological bone union was achieved in all the operated wrists. At final follow-up of ten patients after 6 years, they had a substantial reduction in pain and improvement in daily function and grip strength compared with those before arthrodesis. We conclude from outcomes of this series that the conversion to arthrodesis after failed wrist arthroplasty is worthwhile and reliably improve wrist function over failed wrist arthroplasty. The results suggest that the patients who will have wrist arthroplasty can be assured that in case of failure the conversion to arthrodesis will produce outcomes comparable with those after primary arthrodesis.

Background Wrist anatomy variability is associated with differing susceptibility to pathology. For example, a flat radial inclination is associated with Kienbock's disease. Lunate facet inclination (LFI) also exhibits variability. Its relationship with other wrist features is poorly documented. Purposes We tested the hypothesis that high LFI is associated with increased uncovering of the lunate, negative ulnar variance (UV), and type 2 lunates to balance forces across wrists. Methods In total, 50 bilateral and 100 unilateral wrist posteroanterior radiographs were reviewed. Lunate type, lunate uncovering index (LUI), lunate tilting angle (LTA), UV, and sigmoid notch angle (SNA) were measured, and correlation with LFI was assessed on 150 right wrist radiographs followed by an assessment of differences based on lunate morphology. Symmetry of 50 bilateral wrists was assessed. Results There was no correlation of LFI with lunate morphology, LUI, and LTA. There was a low correlation of LFI with SNA and UV. There was an inverse relationship between UV and SNA. Wrists with type 2 lunates had more oblique sigmoid notches and higher LTA in comparison to wrists with type 1 lunates. Side-to-side comparison revealed strong correlation except for LUI, which exhibited moderate correlation. Conclusions There is no correlation between LFI, LUI, and lunate morphology. Type 2 lunates are associated with higher LTA and more oblique SNA. Wrists were symmetrical. Clinical Relevance Factors other than lunate morphology are essential in balancing forces across wrists. A better understanding of soft tissue and other factors will improve the understanding of wrist biomechanics and pathology. Contralateral wrist radiographs can guide reconstructive surgery.

Idag existerar det inga produkter på marknaden för att objektivt kunna mäta radiokarpalledens styrka vid extensionen. Små skador på radiokarpalleden har stor inverkan på den enskilde individen. Syftet med detta projekt är att utveckla en grundläggande lösning för att objektivt mäta kraften i handleden (radiokarpalleden). Arbetsmetoden har följt principkonstruktionsmetoden i produktutveckling (F.Olsson, 1995). Viktningsverktyget har använts för att jämföra och ranka lösningsidéer mot varandra. Idéerna har genererats i brainstorming (BAD) som arbetsmetod och verifierats genom fysiska (MAD) och digitala (CAD) modeller. Lösningsförslag har ritats upp i CATIA V5 R20 där även finita element (FEM) analyser har gjorts för att verifiera lösningsförslagens rimlighet. Idéerna har jämförts och förfinats till en principiell lösning som uppfyller de erhållna kraven. Detta projekt har resulterat i en verifierad CADmodell som på principnivå objektivt kan mäta kraften i radiokarpalleden.

This dissertation summarizes the research effort to develop a novel, three degree-of-freedom device that is ideally suited as a robotic wrist or platform manipulator. Because of its similarity to the human wrist, this invention has been named the "Carpal Wrist." Much like its natural counterpart, the Carpal Wrist has eight primary links, corresponding to the eight carpal bones of the human wrist, a parallel actuation scheme, similar to the flexor and extensor carpi muscles along the forearm, and an open interior passage, which forms a protected tunnel for routing hoses and electrical cables, much like the well-known carpal tunnel. The Carpal Wrist also has the significant advantages of possessing closed-form forward and inverse kinematic solutions and a large, dexterous workspace that is free of interior singularities (either considered separately or as part of a manipulator arm). As a result of its symmetric parallel architecture, the Wrist can handle a large payload capacity and can easily be adapted to a variety of actuation schemes. While parallel-architecture manipulators have long been recognized for their high-rigidity and large payload-to-weight capacity, few have been developed for application, primarily because of complications in kinematic and dynamic modeling. The mathematical model of any manipulator must be developed in order to allow the necessary motion control of the device. The mathematical model provides a mapping from the input space (called joint space) to the output space (called tool space) of the manipulator. Given a desired task in terms of motion of the robot tool, the mathematical model determines the required motor input parameters. Advanced manipulator performance through automatic control becomes possible when the model includes inertial or dynamic effects of the manipulator and tool. The research leading to the development of the Carpal Wrist is significant because it presents a complete kinematic and dynamic model of a parallel-architecture manipulator, and thus will provide significant improvement over current serial robot technology. This research was funded in part by TRIAD Investors Corporation (University Partners), Baltimore MD.

Resumo:

Wrist orthoses are the most common upper limb orthoses, being used by thousands of individuals each year to stabilize, immobilize, or support the wrist joint. Wrist orthoses achieve their function by altering the stiffness of the wrist joint (Figure 1-1). However, there is no quantitative understanding of how wrist orthoses affect wrist stiffness, and consequently, wrist orthosis development often relies on feel, intuition, or empirical heuristics rather than a methodical, quantitative approach. Because wrist movement control is dominated by wrist joint stiffness (Charles and Hogan 2011) a quantitative understanding of how wrist orthoses alter the stiffness of the wrist is imperative to the development of improved wrist orthoses with properties tailorable to the needs of the thousands of individuals who use them. In order to begin bridging this gap, our research characterized the stiffness of four common groups of wrist orthosis in two degrees of freedom: flexion-extension (FE) and radioulnar deviation (RUD) which are the degrees of motion most affected by wrist orthoses. We used a wrist robot to measure how twelve orthoses altered the passive wrist stiffness of twenty healthy subjects (three orthoses and five subjects per orthosis group). To perform these measurements we designed a unique wrist-mounting fixture (Figure 3-2) which allows the wrist robot to manipulate the hand inside an orthosis without interfering with orthosis motion (more accurately simulating the actual hand-orthosis interaction). Our results showed that (1) three out of four orthosis groups significantly altered the stiffness of the wrist joint, (2) orthoses in the same group are not generally significantly different than one another, and (3) there are important differences in stiffness between different orthosis groups. An interesting implication of our research is the result that in many cases orthoses with volar stays may be interchanged with orthoses with both volar and dorsal stays without significant changes in orthosis performance (Table 4-2). We anticipate this work will prove fruitful toward the future study of wrist orthoses' effects on wrist movement behavior and the future improvement of wrist orthosis design.

Over the past three decades, much research in motor neuroscience has focused on understanding how humans make coordinated reaching movements, yielding valuable insight into the planning and control of reaching movements, and establishing a foundation for robot-assisted rehabilitation. The goal of this doctoral research was to provide a quantitative characterization of humans' wrist rotations, paving the way for intelligent robot-assisted wrist rehabilitation. More specifically, we have characterized the kinematics, dynamics, and adaptation of wrist rotations, and discussed implications for planning and control. Kinematics: It is well known that humans make relatively straight reaching movements, suggesting that reaching movements are primarily under kinematic control of hand position. We used a motion capture system to test if wrist rotations are also under kinematic control. We found that wrist rotations exhibit a pattern with significantly more path curvature and variability than reaching movements (p = 0.001). While the increased path curvature could indicate that wrist rotations are not under kinematic control, this work provides evidence that the curvature is instead due to imperfect peripheral execution.Dynamics: In order to determine the exact cause of path curvature, an anatomically-accurate, mathematical model of the wrist was developed, including recent measurements of passive wrist stiffness. Combining experimentally-measured kinematics from human subjects with the wrist model revealed that moderately-sized wrist rotations can be approximated by a very simple model with virtually no loss in accuracy.Interaction torques, for which the nervous system compensates in reaching movements, are present but negligible in wrist rotations.
(cont) Rather, wrist rotation dynamics are dominated by stiffness, which was shown to be the likely cause of path curvature.Adaptation: When perturbed during reaching movements, humans adapt by straightening their paths, confirming that kinematics play a prominent role in planning reaching movements. We found that subjects consistently adapted to a conservative,velocity-dependent force field. Interestingly, this adaptation was more difficult to detect than in perturbation studies involving reaching movements. Taken together, these results suggest that wrist rotations are also primarily under kinematic control (albeit imperfect).

Abstract The singularities of manipulators with offset wrists are difficult to enumerate. The wrist offset “skews” the known regional arm singularities and wrist singularities of the zero-offset case. This paper illustrates the problem for a specific example.

Abstract Distraction of the wrist via external fixation is used to effect and protect the reduction of distal radius fractures by applying tension to the wrist ligaments, a principle known as ligamentotaxis. Wrist and finger stiffness has been associated with overdistraction of the wrist through external fixation (Kaempffe, 1993; Sanders, 1991). A decrease in the range of motion at the metacarpophalangeal (MP) and proximal interphalangeal (PIP) joints has been shown to occur as distraction increases (Moran, 1992). Empirically proposed guidelines for attaining adequate distraction (Agee, 1994; Seitz, 1993) have not been experimentally substantiated. We tested uninjured cadaver wrists to correlate progressive tension across the wrist with associated carpal distraction. To provide a clinically useful method to assess ligamentotaxis, we evaluated the relationships between separation of joint spaces, applied distraction, and the tension carried across the wrist.

The majority of the manipulation tasks requires the motion of the end effector from an initial pose to a final one without particular conditions on the path. Thus, the reduction of the practicable paths between two any poses is a possible choice, exploitable at the design stage, for simplifying manipulator’s hardware. This choice is adopted in under-actuated manipulators. The (nS)-2SPU wrist is one out of the under-actuated parallel wrists this author proposed in a previous paper. Here, the kinematic analysis of this wrist is studied. Both its finite and its elementary kinematics are considered. It is shown that its control algorithms can be written by using simple closed-form formulas, which can take advantage from the wide literature on spherical four-bar linkages. And the demonstration that its singular configurations can be avoided more easily than the ones of the fully-parallel wrist is provided.

Resumo:

Osteoarthritis (OA) is a serious and frequently occuring outcome of untreated scapholunate dissocation, the most common form of carpal instability in the wrist [1]. As cartilage degenerates, the water content of surrounding tissue becomes less bound. Magnetic resonance imaging (MRI) T2 relaxation time is longer when water content is less bound [2]. MRI offers the advantageous combination of detailed images of soft tissues such as cartilage with the ability to evaluate free water content. Contrasting the various T2 relaxation times found in the cartilage of healthy wrist surfaces with those of injured wrists is thereby proposed as a method of evaluating cartilage degeneration. We hypothesized that T2 values obtained would be longer for the cartilage of the injured wrists. Though surgical treatment may relieve pain and restore some function to the wrist, it is hypothesized that T2 relaxation time will remain increased after surgery as cartilage regeneration is a very slow process, if it happens at all. The goal of this research is to provide a method to evaluate the biochemical and infer the biomechanical integrity of cartilage for various cartilage surfaces in a wrist after injury.

Abstract The wrist is critical to people’s activities of daily living, which consists of two major degrees of freedom (DOF) — flexion-extension (FE) and radial-ulnar-deviation (RUD). This paper proposes a novel 2-DOF biomimetic robotic wrist design for a forearm mannequin, which is developed as a safe test bench that emulates human forearm movements for exoskeleton experimentation. Due to the complexity of the coupled motions of FE and RUD, existing robotic wrists mainly focus on the FE motion, and sometimes incorporate the forearm pronation/supination instead of the RUD motion. To solve this issue, the robotic wrist features a simple but effective hybrid mechanism for FE and RUD motions, which avoids the axes offset between FE and RUD from producing unnatural wrist movements and allows ranges of motions comparable to those in a human wrist. We analyze the kinematics of the hybrid wrist mechanism, which leads to the establishment of the dynamical model through a generic constrained multibody formulation. A robust controller is then adopted for reference trajectory tracking control. We then perform numerical simulations, which validate the control performance and actuator choice, and evaluate the workspace, rotation axes offset, and inertial characteristics. The results preliminarily verify the biomimetic robotic wrist as a feasible solution for the forearm mannequin to realize natural wrist movement emulation.

In a previous work, this author showed that ten topologies for under-actuated parallel wrists can be generated from the fully-parallel wrist. Three of them are obtained by simply replacing a spherical pair (S) with a nonholonomic spherical pair (nS). The S-(nS)PU-SPU, and S-(nS)PU-2SPU wrists are two of these three. The position analysis of these two wrists is studied in this paper. In particular, all the four position-analysis problems, which are necessary for implementing their path planning, are addressed and solved in closed-form. Despite their different topology, the position-analysis of these two wrists can be practically solved by using the same formulas and algorithms. Based on the deduced formulas, a path-planning algorithm is proposed. The obtained results make the studied wrist topologies able to replace “ordinary” wrists in the manipulation tasks which do not require tracking.

Abstract Much work has been done related to the qualitative osseous anatomy of the wrist yet there are still very few references for its quantitative geometric, biomechanic, or kinematic characteristics.1–3 Because of the structural complexity and morphological variations of the wrist, a reference database of normal anatomy and kinematics would provide valuable reference information which will facilitate diagnosis and treatment of various injuries and diseases.

Abstract This paper presents a method for analyzing dexterity of manipulators comprising spherical wrists. The goal is to provide the user with knowledge of orientability of the end-effector at a target. Wrist accessible output sets are determined analytically by first determining manipulator singularities, followed by back substituting the singularities into the constraint equations to parametrize surfaces. Since regions of a surface may exist inside the wrist accessible output set, and other regions on the boundary, surfaces are segmented into subsurfaces. To determine whether a subsurface is an internal or boundary one, each subsurface is studied for existence inside the wrist accessible output set by perturbing a point along its normal. Closed-form solutions of the boundary of the wrist accessible output set are obtained. A service sphere is located at an operating point in the accessible output set and the sphere is intersected with the boundary sub-surfaces. The intersection curves are computed and projected onto the space of a cylinder, then the cylinder is unrolled to depict a map. Dexterity charts are introduced as maps depicting orientability of the end-effector at a target.

Spontaneous tendon ruptures of the wrist are a rare pathology, usually secondary to rheumatoid arthritis or distal radius fractures and most commonly evolving the extensor pollicis longus. Sport-related etiology is a growing tendency of this pathology. As far as the authors know, this is one of the first sport-related extensor carpi radialis brevis (ECRB) isolated spontaneous rupture described in the literature. We describe a case of a 41 year-old female amateur kickboxer who developed acute dorsal radial pain in the right wrist during practice. After attempting conservative treatment for 4 months with rest and NSAIDs she recurred at our clinic. Local pain at dorsal wrist extension was observed. MRI demonstrated an isolated ECRB rupture with associated fibrous tissue proximal to the extensor retinaculum. Surgical management was proposed and consisted of fibrous tissue debridement and ECRB-ECRL tenodesis. At 3 months of follow-up the patient reported return-to-play with impaired wrist motion and mild pain at maximum wrist extension. At 12 months of follow-up the patient was completely recovered and asymptomatic. Isolated tendon ruptures are a rare pathology, causing extreme pain and disability in the sport setting. Surgical management of this ECRB tendon rupture by tenodesis allowed for appropriate pain control and functional results and early return-to-play.
