This study investigated the effects of exertion, pace and level of simple and combined flexion/extension and radial/ulnar deviation of the wrist on discomfort for simple repetitive exertions. Eight male subjects participated in the study and the level of exertion and angular deviation were defined relative to the maximum strength and Range of Motion (ROM) of the subjects respectively. Extreme flexion caused higher discomfort than the other simple types of deviation, and the combination of flexion and ulnar deviation resulted in higher discomfort than the other types of combined deviation. Exertion was the most significant factor, followed by level of deviation.

The Difference

Background: The cervical collar has been used as a common device for the initial stabilization of the cervical spine. Although many cervical collars are commercially available, there is no consensus on which offers the greatest protection, with studies showing considerable variations in their ability to restrict cervical range of motion. The use of the XCollar (Emegear, Carpinteria, CA) has been known to decrease the risk of spinal cord injury by minimizing potential cervical spinal distraction. We compared XCollar with two other cervical collars commonly used for adult patients with cervical spine injury to evaluate the difference in effectiveness between the three cervical collars to restrict cervical range of motion. Objectives: This study aimed to evaluate the difference between the three cervical collars in their ability to restrict cervical range of motion. Method: A total of 30 healthy university students aged 21–25 years participated in this study. Participants with any cervical disease and symptoms were excluded. Three cervical collars were tested: Philadelphia® Collar, Stifneck® Select™ Collar, and XCollar. A digital camera and an image-analysis technique were used to evaluate cervical range of motion during flexion, extension, bilateral bending and bilateral axial rotation. Cervical range of motion was evaluated in both the unbraced and braced condition. Results: XCollar permitted less than a mean of 10° of movement during flexion, extension, bilateral bending and bilateral axial rotation. This was less than the movement permitted by the other two cervical collars. Conclusion: XCollar presented superior cervical immobilization compared to the other two commonly used cervical collars in this study. Thus, when cervical collar is considered for an adult patient with cervical spine injury, XCollar might be one of the considerate options as a cervical immobilization device.

Radioscapholunate Arthrodesis

Radioscapholunate arthrodesis is a salvage procedure indicated for osteoarthritis of the radiocarpal joint involving the lunate facet of the radius. This cadaver study examines changes in wrist motion resulting from radioscapholunate arthrodesis, and the effects of surgical techniques to improve the range of motion. Simulated radioscapholunate arthrodesis, distal scaphoidectomy and triquetrectomy were carried out sequentially on six cadaver forearms and measurements (maximum flexion/extension and radial/ulnar deviation) were taken in the intact situation and after each surgical step using a magnetic tracking device. Radioscapholunate arthrodesis diminishes the amplitudes of movements of the wrist in all directions, but range of motion in the radioscapholunate fused wrist improves after scaphoidectomy and improves further after triquetrectomy (88% of original flexion/extension and 98% of original radial/ulnar deviation). Radioscapholunate arthrodesis causes a significant change in kinematics between the hamate and the triquetrum in flexion/extension.

The purpose of this study was to evaluate the results of the Universal Total Wrist prosthesis.Seventeen wrist arthroplasties were performed in 15 patients using the Universal Total Wrist prosthesis. The 11 women and 4 men in the study group ranged in age from 45 to 86 years. Fourteen patients had rheumatoid arthritis and one had osteoarthritis. Follow up ranged from 20 to 74 months. Patients were evaluated for range of motion, with the Disabilities of the Arm, Shoulder, and Hand (DASH) survey and radiographically.All range of motion values improved after surgery. Average postoperative motion was 29° dorsiflexion, 38° volar flexion, 7° radial deviation and 17° ulnar deviation. The DASH scores improved with 29 %. Pain score improved in all 15 patients. One prosthesis had to be removed due to component loosening of the carpal plate. The other cases showed no radiographic signs of loosening. One patient had an early prosthetic dislocation and was treated conservatively with success.The Universal Total Wrist prosthesis provides a promising outcome in patients with rheumatoid arthritis.

The Impact

Objective: Wrist-hand orthoses (WHOs) are prescribed for a range of musculoskeletal/neurological conditions to optimise wrist/hand position at rest and enhance performance by controlling its range of motion (ROM), improving alignment, reducing pain, and optimising grip strength. The objective of this research was to study the efficacy and functionality of ten commercially available WHOs on wrist ROM and grip strength.Design: Randomised comparative functional study of the wrist/hand with and without WHOs.Participants: Ten right-handed female participants presenting with no underlying condition nor pain affecting the wrist/hand which could influence motion or grip strength. Each participant randomly tested ten WHOs; one per week, for 10 weeks.Main outcome measures: The primary outcome was to ascertain the impact of WHOs on wrist resting position and flexion, extension, radial, and ulnar deviation. A secondary outcome was the impact of the WHOs on maximum grip strength and associated wrist position when this was attained.Results: From the 2,400 tests performed it was clear that no WHO performed effectively or consistently across participants. The optimally performing WHO for flexion control was #3 restricting 86.7%, #4 restricting 76.7% of extension, #9 restricting 83.5% of radial deviation, and #4 maximally restricting ulnar deviation. A grip strength reduction was observed with all WHOs, and ranged from 1.7% (#6) to 34.2% (#4).Conclusion: WHOs did not limit movement sufficiently to successfully manage any condition requiring motion restriction associated with pain relief. The array of motion control recorded might be a contributing factor for the current conflicting evidence of efficacy for WHOs. Any detrimental impact on grip strength will influence the types of activities undertaken by the wearer. The design aspects impacting wrist motion and grip strength are multifactorial, including: WHO geometry; the presence of a volar bar; material of construction; strap design; and quality of fit. This study raises questions regarding the efficacy of current designs of prefabricated WHOs which have remained unchanged for several decades but continue to be used globally without a robust evidence-base to inform clinical practise and the prescription of these devices. These findings justify the need to re-design WHOs with the goal of meeting users' needs.

Scaphotrapeziotrapezoid (STT) joint fusion was carried out for pain relief in eight patients with isolated arthritis. Seven patients had satisfactory relief of symptoms. The subjective results were excellent in five, good in two and bad in one patient, who had non-union of the arthrodesis and was also the only patient to develop trapeziometacarpal arthritis. Average grip strength was 0.8 and lateral pinch strength was 0.7 of that in the other hand. There was a very small relative difference in dexterity. There was an average difference of 9° of flexion–extension and 13° of radio-ulnar deviation. It is concluded that for isolated idiopathic STT arthritis, fusion gives very satisfactory results with minimal complications.

Repetitive Trauma

In order to minimize the risk of repetitive trauma injuries, postures or motions that place joints near the limits of their range of motion (RoM) should be avoided. Before it can be determined that a posture or motion approaches the limit of a joint's motion, these limits need to be established. Previous research on wrist functionality has focused almost entirely on RoM in two or three isolated planes (flexion/extension, radial/ulnar deviation, and forearm pronation/supination), without investigating potential effects of complex wrist/forearm posture on RoM. Since most practical applications of this wrist motion data involve more than these isolated planar deviations, the effects of complex wrist/forearm posture on wrist functionality need to be understood.

This study aims to compare a new inertial measurement unit based system with the highly accurate but complex laboratory gold standard, an optoelectronic motion capture system. Inertial measurement units are sensors based on accelerometers, gyroscopes, and/or magnetometers. Ten healthy subjects were recorded while performing flexion-extension and radial-ulnar deviation movements of their right wrist using inertial sensors and skin markers. Maximum range of motion during these trials and mean absolute difference between the systems were calculated. A difference of 10° ± 5° for flexion-extension and 2° ± 1° for radial-ulnar deviation was found between the two systems with absolute range of motion values of 126° and 50° in the respective axes. A Wilcoxon rank sum test resulted in a no statistical differences between the systems with p-values of 0.24 and 0.62. The observed results are even more precise than reports from previous studies, where differences between 14° and 27° for flexion-extension and differences between 6° and 17° for radial-ulnar deviation were found. Effortless and fast applicability, good precision, and low inter-observer variability make inertial measurement unit based systems applicable to clinical settings.

We present results of four-corner carpal arthrodesis with the Acumed® HubcapTM circular plate performed at our unit. Eight patients underwent eight procedures over five years, for scapholunate advanced collapse (five wrists) and scaphoid non-union advanced collapse (three wrists). Outcomes included range of motion, quickDASH scores, and visual analogue scores for satisfaction. At final follow-up, mean flexion-extension arc was 56°, mean radial-ulnar deviation 29° and mean quickDASH score was 23/100. Mean score for satisfaction was 7.7/10 (77%). Seven out of eight (87.5%) patients said they would have it done again, and would also recommend it to others. Radiological union was achieved in all cases. One screw broke in one arthrodesis without causing symptoms. The functional outcomes with our use of the HubcapTM are comparable to those reported in literature to date with other circular plates (e.g. Spider plate). There were no non-unions, which is the main reported complication with these plates.

Purpose: A biomechanical functional assessment was performed on a newly designed wrist hemiarthroplasty implant with aimed to identifying differences between the native wrist and wrist following the hemiarthroplasty procedure with [Formula: see text] and without a proximal row carpectomy (Hemi). Methods: Six cadaveric wrists were mounted on a custom testing fixture and underwent a series of functional tests to investigate differences in range of motion, muscles moment arms, and axis of rotation between the intact and post-operative wrists. The tested movements included manually-driven flexion-extension, radial-ulnar deviation, dart throwers motion, and circumduction. Results: The only significant change in range of motion was a decrease in flexion between the intact [Formula: see text] and both the Hemi [Formula: see text] and [Formula: see text] [Formula: see text] conditions. Minor differences in the mean position and variability of the axis of rotation’s piercing point were identified. A statistically significant decrease in the flexion moment arm of the flexor carpi radialis was identified between the intact ([Formula: see text][Formula: see text]mm) and [Formula: see text] ([Formula: see text][Formula: see text]mm) conditions. Statistically significant decreases were also identified in the radial deviation moment arms of the extensor carpi radialis brevis’ between the intact ([Formula: see text][Formula: see text]mm) and [Formula: see text] ([Formula: see text][Formula: see text]mm) conditions and the flexor carpi radialis’ between the intact ([Formula: see text][Formula: see text]mm) and Hemi ([Formula: see text][Formula: see text]mm) conditions as well as in the ulnar deviation moment arm of the extensor carpi ulnaris between the intact ([Formula: see text][Formula: see text]mm) and Hemi ([Formula: see text][Formula: see text]mm) conditions. Conclusions: While some statistically significant functional changes were identified between the native and hemiarthroplasty wrist, the findings suggest that post-operative function is equally acceptable in hemiarthroplasty with and without resection of the proximal carpal row.

Purpose To determine the reliability of wrist range of motion (WROM) measurements based on digital photographs taken by patients at home compared with traditional measurements done in the office with a goniometer. Methods Sixty-nine postoperative patients were enrolled in this study at least 3 months postoperatively. Active and passive wrist flexion/extension and radial/ulnar deviation were recorded by one of the two attending surgeons with a 1-degree resolution goniometer at the last postoperative office visit. Patients were provided an illustrated instruction sheet detailing how to take digital photographic images at home in six wrist positions (active and passive flexion/extension, and radial/ulnar deviation). Wrist position was measured from digital images by both the attending surgeons in a randomized, blinded fashion on two separate occasions greater than 2 weeks apart using the same goniometer. Reliability analysis was performed using the intraclass correlation coefficient to assess agreement between clinical and photography-based goniometry, as well as intra- and interobserver agreement. Results Out of 69 enrolled patients, 30 (43%) patients sent digital images. Of the 180 digital photographs, only 9 (5%) were missing or deemed inadequate for WROM measurements. Agreement between clinical and photography-based measurements was “almost perfect” for passive wrist flexion/extension and “substantial” for active wrist flexion/extension and radial/ulnar deviation. Inter- and intraobserver agreement for the attending surgeons was “almost perfect” for all measurements. Discussion This study validates a photography-based goniometry protocol allowing accurate and reliable WROM measurements without direct physician contact. Passive WROM was more accurately measured from photographs than active WROM. This study builds on previous photography-based goniometry literature by validating a protocol in which patients or their families take and submit their own photographs. Clinical Relevance Patient-performed photography-based goniometry represents an alternative to traditional clinical goniometry that could enable longer-term follow-up, overcome travel-related impediments to office visits, improve convenience, and reduce costs for patients.
