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

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° e

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. A

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.

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 generali

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 smartphon

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.

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 p

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

The standard and positional views of 53 normal wrists have been compared to views taken under stress. The stresses applied can be divided into normal and abnormal ones. All the injured wrists with pathological roentgenographic appearances were operated on and thus the findings confirmed. Roentgenographic examination of the wrist under stress appears to be a valuable and reliable diagnostic aid. Two types of laxity of the wrist and a radio-anatomical classification of wrist instabilities are defined.

The human wrist affects the ability to efficiently perform many manipulation tasks. Despite this, most upper-limb prostheses are focused on the hand’s mobility, which makes users compensate for the lost wrist mobility with complex manipulation strategies relying on the mobility of other body parts. In this context, research on wrist prostheses is still open to new contributions, even though a number of such prostheses are already present in the literature and on the market. In particular, the potential uses of parallel mechanisms in wrist prosthesis design have not been fully explored yet. In

Range of motion, subjective pain, wrist function and X-ray changes were recorded preoperatively and at an average of 3.8 years after operation. Arthroscopic synovectomy of the rheumatoid wrist reduced pain and improved wrist function in the majority of patients. Progress of arthritic degeneration was significantly less common in patients with no, or very early changes at the time of surgery.

No wrist singularities exist (they are forced by design to lie outside of joint limits). However, the existing regional arm singularities become skewed from the well-known singular configurations of common manipulators. The wrist offset also skews the well-known wrist s

Methods: A retrospective chart review of patients undergoing 4CF as well as an interview and recent radiographs were obtained. Patients with a follow-up period of less than 10 years were excluded. Long-term evaluation included standard wrist radiographs, wrist range of motion

OBJECTIVE A thorough understanding of anatomy is critical for successful carpal tunnel release. Several texts depict the median nerve (MN) as taking a course parallel to the long axis of the forearm (LAF). The authors report on their attempt to formally assess the course of the MN as it travels to the carpal tunnel in the distal wrist and discuss its potential clinical significance. METHODS The width of the wrist, the distance from the radial wrist to the MN, and the distance from the distal volar wrist crease to the point where the MN emerges between the flexor carpi radialis (FCR) tendon and

The aim of synovectomy-stabilization (synovectomy combined with the Sauvé–Kapandji procedure) of the rheumatoid wrist is to obtain a stable painless wrist, retaining enough mobility for function. Thirty-nine wrists were retrospectively examined, at a mean follow up of 64.8 months. The improvement in pain was very significant. We noticed a decrease in wrist motion affecting both flexion and radial deviation. The arthritic change in the wrist continued to increase. We noticed a mean ulnar shift of 2.2 mm and a mean increase in the radial deviation of the wrist of 7°. Only transfer of the extenso

An active wrist can deliver both bending and twisting motions that are essential for soft grippers to perform dexterous manipulations capable of producing a wide range movements. Currently, the versions of gripper wrists are relatively heavy due to the bending and twisting motions performed by the motors. Pneumatic soft actuators can generate multiple motions with lightweight drives. This research evaluates a pneumatic soft wrist based on four parallel soft helical actuators. The kinematics models for predicting bending and twisting motions of this soft wrist are developed. Finite element meth
