Abstract
Malignant tumors of the scapula are rare, and limb salvage surgery after tumor resection is challenging. The authors present a series of 6 patients who were treated by total scapulectomy and reconstruction with a custom-made scapular prosthesis and a constrained reverse shoulder arthroplasty. Postoperative oncologic and functional outcomes were assessed. The mean follow-up was 37 months (range, 9-84 months). Clear surgical margins were achieved in all patients. At the last follow-up, 4 patients showed no evidence of disease and 2 had died of systemic metastatic disease. Although shoulder function was limited, all shoulders were painless and stable and the patients retained satisfactory hand, wrist, and elbow function. [Orthopedics. 2018; 41(6):e888-e893.].

Abstract
Tenosynovitis is traditionally recognised at physical examination in patients with inflammatory rheumatic diseases, such as, e.g. psoriatic arthritis and (longstanding) rheumatoid arthritis (RA). The increasing use of sensitive imaging techniques (ultrasound, magnetic resonance imaging (MRI)) has recently revealed that subclinical tenosynovitis is prevalent in early RA and in patients in different phases of RA development (asymptomatic state, arthralgia, early arthritis). In this review, the recent findings on MRI-detected tenosynovitis and associations with RA development are highlighted, and an overview of the most reported inflamed tendon locations within the hand and wrist of patients in different disease phases is provided. The data presented show that tenosynovitis is one of the earliest inflammatory features in patients with imminent RA and associated with impairment of activities in daily life. The value of tenosynovitis as an outcome measure in RA is also discussed.

Abstract
RATIONALE Anomalous course and tenosynovitis of extensor pollicis longus (EPL) tendon is a rare condition that presents clinical symptoms very similar to de Quervain's disease. Herein we report a case of anomalous course and tenosynovitis of the extensor pollicis longus (EPL) tendon associated with symptoms of de Quervain's disease. PATIENT CONCERNS A 44-year-old right-handed man visited the clinic because of radial pain associated with the left wrist, which was aggravated during the previous 10 days. The patient tested positive on the Finkelstein's test and displayed a limited range of motion of the left wrist. Motion of the thumb and wrist aggravated pain. DIAGNOSES Magnetic resonance imaging (MRI) of the left wrist suggested mild tenosynovitis at the third extensor compartment and intersection syndrome. However, clinical symptoms failed to match the MRI findings. INTERVENTIONS A zig-zag skin incision on the radial styloid process was made. The operative findings revealed stenosing tenosynovitis with partial tearing. Retraction of the tendon extended the thumb interphalangeal joint, suggesting that the tendon was the EPL tendon rather than EPB tendon. After operation, we reviewed the MRI of the patient, which revealed that the oblique course of the EPL tendon originated from the ulnar side of the forearm to the radial styloid at the radial and proximal site of Lister's tubercle. No EPB tendon was present. OUTCOMES At 12 months of follow-up, the patient's radial styloid process was completely asymptomatic and resumed full daily activities. LESSONS Anomalous course of the EPL tendon is rarely reported associated with similar symptoms of de Quervain's disease. However, the knowledge and understanding of this potential anomaly in the course of EPL tendon is very important for the treatment of de Quervain's disease to decrease patient dissatisfaction after surgery.

Abstract
OBJECTIVE This paper reports on the quantification of passive wrist joint stiffness and investigates the potential influence of handedness and gender on stiffness estimates. METHODS We evaluated the torque-angle relationship during passive wrist movements in 2 degrees of freedom (into flexion-extension and radial-ulnar deviation) in 13 healthy subjects using a wrist robot. Experimental results determined intrasubject differences between dominant and nondominant wrist and intersubject differences between male and female participants. RESULTS We found differences in the magnitude of passive stiffness of left- and right-hand dominant males and right-hand dominant females suggesting that the dominant hand tends to be stiffer than the nondominant hand. Left-hand stiffness magnitude was found to be 37% higher than the right-hand stiffness magnitude in the left-handed male group and the right-hand stiffness magnitude was 11% and 40% higher in the right-handed male and female groups, respectively. Other joint stiffness features such as the orientation and the anisotropy of wrist stiffness followed the expected pattern from previous studies. CONCLUSION The observed difference in wrist stiffness between the dominant and nondominant limb is likely due to biomechanical adaptations to repetitive asymmetric activities (such as squash, tennis, basketball, or activities of daily living such as writing, teeth brushing, etc.). SIGNIFICANCE Understanding and quantifying handedness influence on stiffness may have critical implication for the optimization of surgical and rehabilitative interventions.

Abstract
PURPOSE To present a new arthroscopic method for treating supination losses. METHODS Six patients (15-71 y) were eligible for this study. All had a history of trauma to the wrist more than 6 months previously. Five of them had sustained a distal radius fracture: 3 had been treated with a volar plate (1 of them for an extra-articular malunion), 1 with an external fixator and K-wires, and 1 had been treated in a cast. One of these patients underwent a further operation for correcting an intra-articular malunion. The last patient underwent an open reduction of a transscaphoid perilunate dislocation. During a standard radiocarpal arthroscopy, a curved periosteal elevator was inserted through the 6R portal into the volar-radial corner of the triangular fibrocartilage complex and advanced proximally gliding on the anterior ulnar head surface. The volar capsule was then distended with the periosteal elevator and by means of gentle sweeping motion adherences between them, the volar capsule and the ulnar head were freed. Finally, the arthroscopic release was combined with a gentle passive supination force applied by the surgeon. Full supination was maintained in an orthosis for 2 to 3 days. Afterward, regular physical therapy was instituted. Concomitant surgery, arthroscopic or open, was performed in all to treat associated conditions. RESULTS Full supination (90°) was achieved in all intraoperatively. At a mean follow-up of 3.3 years, mean supination was 76° in the latest follow-up (range, 50° to 90°). Mean improvement in supination was 80° (range, 50° to 100°). No distal radioulnar instability or other complications were noted. CONCLUSIONS The method presented proved effective in severe forms of supination deficits. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic V.

Abstract
BACKGROUND Disability of the upper limb is one of the consequences of distal radius fracture (DRF). The outcome of DRF treatment is based on objective clinical variables, as strength or range of movement (ROM); sometimes these variables do not correlate with the functional level of the patient. The principal objective of our study was to assess the repercussion of conservative treatment of DRF on upper limb disability. METHODS This is a retrospective review of prospectively collected data. We collected data of 61 nonconsecutive DRFs treated conservatively from July 2007 to August 2008. RESULTS Average Disabilities of the Arm, Shoulder and Hand (DASH) score before fracture was 20.8 points; average DASH score after the fracture was 42.6. There was a significant increase in the upper limb disability after 1 year of follow-up in the patients treated conservatively ( P < .001; size effect, 1.06). Average radial inclination, radial tilt, and radial length were 18.18°, 3.35°, and 5.76 mm, respectively. Average ROM for flexion-extension was 100.6° and for pronation-supination 144.0°. ROM for flexion-extension of the unaffected wrist was 128.2° and for pronation-supination 172.4°. We did not find any significant statistical correlation between the increase in disability and the decrease in the ROM ( P > .05). We did not find any significant statistical correlation between the increase in the disability and the worsening in the radiological parameters ( P > .05). Our results confirm the hypothesis that the conservative treatment of DRF produced an increase in the upper limb disability after 1 year of follow-up. CONCLUSIONS Our study does not show a correlation between the increase in upper limb disability and the decrease in wrist ROM. Our study did not find a correlation between radiological measures and DASH scores.

Abstract
RATIONALE Dislocation of the distal radioulnar joint and injury to distal forearm are commonly encountered. However, delayed diagnosis or misdiagnosis has been relatively rare due to improved diagnosis and treatment. Treatment of old dislocation of radioulnar joint is challenging due to development of secondary chronic instability and difficulties in restoration of joint function. PATIENT CONCERNS This report describes three cases of patients complained about inability to extend their little fingers. DIAGNOSES Local examination and X-ray revealed chronic ulnar joint dislocation. INTERVENTION Wrist arthroplasty was used to perform ulnar distal articular cleansing and repair of the triangular fibrocartilage complex (TFCC) articular cartilage. The Sauve-Kapandji osteotomy was performed to treat radial joint dislocation and stabilize ulnar joint. Repair of spontaneous fracture of the extensor tendon was also performed. Postoperative gypsum was used for immobilization for 4 weeks. OUTCOMES The follow-up results are reported. Based on Cooney wrist score, the preoperative scores were poor (55, 50, 60), while the post-operative scores were excellent (90, 85, 90) in all 3 cases. LESSONS Early and accurate diagnosis and treatment is important for the recovery of distal radius fracture for patients with dislocation of the ulnar joint. The correct treatment determines the degree of later functional recovery. Early surgical treatment is recommended for patients with unsatisfactory reset. Delayed diagnosis and treatment often lead to chronic and persistent lower ulnar joint subluxation or dislocation, or even osteoarthritis. All patients in this report showed great improvement in wrist function after surgery.

Abstract
OBJECTIVE To investigate the association of high baseline serum levels of metalloproteinases-3 (MMP-3) with structural damage to hand and feet joints, assessed by ultrasonography (US), in patients with early, treatment-naïve rheumatoid arthritis (RA), without initial X-ray-visible erosions, during 24 months follow-up. METHODS Sixty-three early RA (European League Against Rheumatism/American College of Rheumatology 2010), disease-modifying anti-rheumatic drugs/glucocorticoid naïve patients (mean age 53.4 ± 14.1) with symptom duration ≤12 months, had baseline serum levels of MMP-3 tested. OMERACT US group definition was used to detect the presence, as well as longitudinal diameter of erosions by US at study entry and after 24 months, at the level of wrists, metacarpophalangeal (MCP2/MCP5) joints of both hands, and fifth metatarsophalangeal joints. RESULTS Complete data were collected from 52 out of 63 patients. High baseline serum levels of MMP-3 (MMP-3-positive) were found in 46/63 patients. 122 bone erosions in total (1.9 bone erosions/patients) were detected by US at baseline visit and 213 erosions (4.3/patients) after 24 months. MMP-3 positive patients had significantly higher total number of erosions than MMP-3-negative (p = 0.039) and higher increase in size of bone erosions in the feet but not in the hand joints after follow-up (OR 4.82 [1.23-18.9], p = 0.024; OR 1.17 [0.320-4.26], p = 0.816 respectively). CONCLUSION After 2 years of follow-up, US assessment showed a higher number of new bone erosions in MMP-3-positive compared to MMP-3-negative patients with early RA and no visible initial radiographic changes. High baseline levels of MMP-3 predict significantly higher structural damage progression at the level of feet, but not at the level of hand joints.

Abstract
The Sauvé-Kapandji procedure is a reliable option for patients with various disorders of the distal radioulnar joint (DRUJ). However, postoperative pain over the proximal ulnar stump frequently develops during forearm rotation or when lifting heavy objects, although many clinically satisfactory results have been reported. This stump pain has been suggested to result from dynamic instability of the proximal ulnar stump. Several types of tenodesis have recently been performed simultaneously with the Sauvé-Kapandji procedure to stabilize the proximal ulnar stump and thus relieve the associated pain. Although satisfactory outcomes of these stabilization procedures have been reported, correlations of the residual symptoms and radiographic findings between the conventional method and the modified method. Additionally, the mechanism of pain relief remains unclear.To elucidate the cause of proximal ulnar stump pain, the clinical results and radiographic changes were compared between 2 treatment groups in which different Sauvé-Kapandji procedures had been performed. Twenty-four wrists with distal radioulnar disorders, all of which had undergone Sauvé-Kapandji procedures, were retrospectively classified into 2 groups according to the procedure. Group A (13 wrists) was treated by the conventional surgical procedure, in which the proximal ulnar stump is not stabilized. Group B (11 wrists) was treated by the modified method, in which the proximal ulnar stump is stabilized by tenodesis with the extensor carpi ulnaris tendon. Wrist pain, proximal ulnar stump pain, ranges of forearm pronation/supination, and grip strength were investigated. The ulnar distance, ulnar gap, interosseous distance, and dorsopalmar distance were measured on both resting and dynamic radiographs.Stump pain was recognized in 6 wrists in group A and 0 in group B. However, no substantial differences in the other clinical findings or 4 radiographic parameters were found between the 2 groups.These findings suggest that stabilization of the proximal ulnar stump cannot correct either dorsal ulnar deviation or dorsal displacement of the radius. Therefore, proximal ulnar stump pain may not be caused by either radial or dorsal deviation of the proximal ulnar stump but instead by other dynamic factors.

Abstract
The purpose of this study was to compare the treatment results of sonography-guided arthroscopic excision for volar and dorsal wrist ganglions. A total of 42 patients with wrist ganglions underwent sonography-guided arthroscopic resection. Clinical outcome measures included wrist range of motion, grip strength, patient-rated questionnaire Hand20, and numerical pain rating scale. All patients were assessed for recurrence throughout the follow-up period. Ganglions were located at the dorsal wrist in 26 cases and at the volar wrist in 16 cases. The mean Hand20 and pain scores were significantly improved after sonography-guided arthroscopic resection for both volar and dorsal wrist ganglions. Recurrence was seen in six cases (23%) of dorsal wrist ganglion but no cases of volar wrist ganglion (P < .05). The use of sonography-guided arthroscopic ganglion excision is better for treating volar wrist ganglion than dorsal wrist ganglion.

Abstract
AIM To investigate the effects of chronic flexed wrist posture following spasticity on the elasticity and cross-sectional area (CSA) of the median nerve at the carpal tunnel among chronic stroke patients. MATERIAL AND METHOD This prospective study included 24 consecutive patients (mean age, 56.5±11.56 years) with unilateral wrist spasticity following a stroke in a chronic phase. The CSA of the median nerve was measured by ultrasound (US). The elasticity was measured by Virtual Touch tissue imaging quantification (VTIQ; Siemens, Erlangen, Germany). SWV and CSA of the median nerves of the affected and unaffected sides for each patient were compared. The correlations between duration of time since the stroke, SWV and CSA of the median nerve were assessed. The interobserver agreement was assessed. RESULTS The CSA of the median nerve at the affected side was significantly lower than that of the unaffected side (p = 0.03). The SWV of the median nerve at the affected side was significantly higher than that on the unaffected side (p < 0.001). The interobserver agreement was excellent for both CSA and SWV measurements. There was a negatively fair correlation between CSA at the affected side and duration of time since stroke (r = -0.58, p < 0.05). The SWV of the median nerve at the affected side was not correlated with the duration of time since stroke (r ≤ 0.3, p ≥ 0.05). CONCLUSIONS These results suggest that chronic flexed wrist posture may cause atrophy of the median nerve due to chronic compression after stroke and increase in the stiffness of the median nerve.

Abstract
BACKGROUND Despite the pervasive and devastating effect of Essential Tremor (ET), the distribution of ET throughout the upper limb is unknown. We developed a method for characterizing the distribution of ET and performed a preliminary characterization in a small number of subjects with ET. METHODS Using orientation sensors and inverse kinematics, we measured tremor in each of the seven major degrees of freedom (DOF) from the shoulder to the wrist while ten patients with mild ET assumed 16 different postures. We described the tremor in each DOF in terms of power spectral density measures and investigated how tremor varied between DOF, postures, gravitational torques, and repetitions. FINDINGS Our method successfully resulted in tremor measures in each DOF, allowing one to compare tremor between DOF and determine the distribution of tremor throughout the upper limb, including how the distribution changes with posture. In our small number of subjects, we found that the amount of power in the frequency band associated with ET (4-12Hz) was lowest in the shoulder and greatest in the wrist. Similarly, the existence and amplitude of peaks in this band increased from proximal to distal. Although the amount of tremor differed significantly between postures, we did not find any clear patterns with changes in posture or gravitational torque. INTERPRETATION This method can be used to characterize the distribution of tremor throughout the upper limb. Our preliminary characterization suggests that the amount of tremor increases in a proximal-distal manner.

Abstract
PURPOSE OF THE STUDY The purpose of our retrospective study is to evaluate 5-year functional and radiological outcomes in patients following corrective osteotomy of the distal radius and ulnar osteotomy for malposition after a distal radius fracture, to identify differences in the outcomes of corrective osteotomies depending on the type of the original fracture according to the AO classification, the grade of arthritis of radiocarpal (RC) joint, surgical approach and the way of stabilisation of the osteotomy. MATERIAL AND METHODS The followed-up group of 22 patients (8 men and 14 women) underwent osteotomy for malposition of distal radius in the period 2007-2011. The age of patients in the followed-up group ranged from 21 to 72 years, with the mean age of 51 years at the time of surgery. The indications for corrective osteotomy due to distal radius deformity were the following: functional limitation, pain and radiological parameters confirming the deformity. The opening wedge osteotomy of distal radius performed through volar or dorsal approach, isolated shortening osteotomy of ulna and a combination of both the methods were used. The observations included: the original type of fracture according to AO/OTA classification, functional outcomes - Disabilities of the Arm Shoulder and Hand (DASH) score, Mayo Wrist Score (MWS), range of motion, grade of wrist arthritis and specific complications. The follow-up period was 5 years. RESULTS Average results were obtained in the group of patients before/after the osteotomy: DASH score- 35/14, MWS- 54/77, flexion- 44°/64°, dorsiflexion- 48°/61°, supination- 75°/79°, pronation- 72°/83°, ulnar duction- 20°/23°, radial duction- 9°/16°, grip strength in percentage- 59%/83%. After osteotomy, a statistically significant increase was observed in flexion, dorsiflexion, supination, pronation, radial duction, ulnar duction, grip strength in percentage, MWS, while in the DASH score a statistically significant decrease was reported. Based on the statistical evaluation of differences in functional outcomes after osteotomy, in patients with type A and C original distal radius fractures no difference in range of motion parameters was found after osteotomy. As to the mean values, the flexion and dorsiflexion range of motion was greater by 10° in patients after extra-articular osteotomy for malposition following the type A original fracture as compared to the type C fracture. By measuring the Joint Space High (JSH) ratio, no statistically significant changes were found regarding the progression of arthrosis of the radiolunate and radioscaphoid part of the RC joint as against the arthrosis in patients up to 5 years after corrective osteotomy of the distal radius. In patients with distal radius malposition and RC joint grade 1-2 arthritis according to the Knirk and Jupiter classification, better functional outcomes were achieved than in the limited and total wrist arthrodesis. In our patients, at 5 years after osteotomy no worsening was observed of the existing wrist arthritis and no arthritis was newly diagnosed. Specific complications were found in 4 cases (18.2 %). In 2 patients after radial osteotomy from dorsal approach (extensor tendon irritation, rupture of the long extensor tendon of the thumb), removal of osteosynthesis material was necessary in both the patients. In one patient after the isolated ulnar shortening osteotomy, an intraoperative fissure of distal ulnar fragment was detected, which healed without any further complications. In one patient an iatrogenic fracture of anterior superior iliac spine was observed after harvesting the corticospongious graft from the ala of the ilium. DISCUSSION Corrective osteotomy is a well-established method for treating distal radius deformities following a fracture. Even at present, there are various opinions regarding the indications, contraindications, timing of the surgery, osteotomy technique and the need to use a bone graft. Limited or total wrist arthrodeses in the area of wrist arthrosis and deformities bring good results with respect to the pain relief, but a limited range of motion occurs mainly in younger patients. Bearing this in mind, in grade 1-2 wrist arthritis in patients with distal radius deformities, a better functional outcome can be achieved by osteotomy. By using dorsal or volar approach, comparable outcomes can be obtained, but with the dorsal approach there is higher frequency of complications and the need to remove the osteosynthesis material. CONCLUSIONS Corrective osteotomies resulted in an improved functional outcome in the treatment of deformities after a distal radius fracture. Apart from deformity correction, the treatment has been affected also by the RC joint arthritis. The study confirmed neither statistically significant differences in the osteotomy outcomes in patients with the original type A or type C distal radius fracture according to the AO classification, nor the statistical significance of the RC joint arthritis. Our results have proven better functional outcomes of deformity correction achieved by osteotomy in case of grade 1 and 2 arthritis than by the limited wrist arthrodesis. In patients showing arthritic changes, no progression was reported within five years after the osteotomy. Key words: distal radius fracture, distal radius deformity, osteotomy, functional results.

The aim is to show the efficacy of 1,2-intercompartmental supraretinacular artery pedicled vascularised bone graft in treatment of scaphoid non-union with concomitant proximal end avascular necrosis retrospectively. Twentytwo cases of scaphoid nonunion with concomitant proximal end avascular necrosis were evaluated. Radiographic evaluation was made with radiographs, computed tomography, and magnetic resonance imaging. Clinical evaluation was made according to the Disabilities of the Arm, Shoulder and Hand (DASH) score, the Mayo wrist score, and the Short Form-36. Union was achieved in 18 81.8%. The mean age was 31.13 ± 5.29 years and the mean follow-up was 34.95±16.87 months. The median wrist flexionextension range was 123.5° (100°-144°) preoperatively and 128° (82°-146°) postoperatively. The median radial-ulnar deviation was measured as 41.5° (24°- 55°) preoperatively and 42° (24°-58°) postoperatively. The dominant hand was measured as 92% (p = 0.061) grip strength compared to the healthy side and the non-dominant side as 74% (p = 0.012). Improvement was observed in all patients in SF-36,DASH,Mayo score and in patients with union (p < 0.001). The radiological and clinical results of this study showed that 1,2- intercompartmental supraretinacular artery pedicled vascularised bone graft is an effective method in the treatment of scaphoid nonunion with concomitant proximal end avascular necrosis.

Abstract
PURPOSE Not all patients with Kienböck disease progress to collapse of the lunate and carpal malalignment, but it is difficult to determine which patients are at risk. We aimed to identify demographic or anatomical factors associated with more advanced stages of Kienböck disease. METHODS We included all 195 eligible patients with Kienböck disease and available preoperative posteroanterior and lateral radiographs. We compared the mean age, sex distribution, mean ulnar variance, radial height, radial (ulnarward) inclination, palmar tilt, anteroposterior distance, and lunate type among the different Lichtman stages of Kienböck disease and performed ordinal logistic regression analysis. RESULTS We found that patients with more negative ulnar variance had more advanced stages of Kienböck disease (adjusted odds ratio, 1.4). An increase in age was also independently associated with a higher Lichtman stage of Kienböck disease (adjusted odds ratio, 1.02). CONCLUSIONS Our findings suggest that more negative ulnar variance may be related to a greater magnitude of lunate collapse in Kienböck disease. Additional long-term study is needed to confirm the longitudinal relationship of negative ulnar variance with progressive Kienböck disease. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.

Abstract
BACKGROUND Carpal tunnel syndrome (CTS) is a common, compressive nerve-entrapment disorder with symptoms of numbness, paresthesia, and pain. Carpal tunnel release surgery is the only known long-term effective treatment. However, surgery is invasive and up to 30% of patients report recurrence or persistence of symptoms or suffer from post-surgical complications. A promising non-surgical treatment for CTS is mechanical wrist traction. The purpose of this study was to evaluate clinical outcomes following mechanical traction in patients with CTS compared to care as usual. METHODS Adult patients (N = 181, mean age 58.1 (13.0) years, 67% women) with electrodiagnostically confirmed CTS were recruited from an outpatient neurology clinic in the Netherlands between October 2013 and April 2015. After baseline assessments, patients were randomized to either the intervention group (12 treatments with mechanical traction, twice a week for a period of 6 weeks) or "care as usual". The main clinical outcome measure was surgery during 6 months' follow-up. In addition, symptom severity was measured using the Boston Carpal Tunnel Questionnaire (BCTQ) at baseline, 3, and 6 months' follow-up. Baseline characteristics and severity of CTS symptoms at follow-up were compared between the intervention and care-as-usual groups using a t test and χ 2 tests. Time to event (surgery) between the groups was analyzed using Kaplan-Meier survival analysis and Cox proportional hazards analysis. RESULTS The intervention group had fewer surgeries (28%) compared to the care-as-usual group (43%) during follow-up (χ21 = 4.40, p = .036). Analyses of the survival curves revealed a statistically significant difference between the groups over time (log-rank test χ 21 = 6.94, p = .008). At 6 months' follow-up, symptom severity and functional status scores had significantly decreased from baseline in both groups (p < .001) and the improvements did not differ between the two groups. CONCLUSIONS Mechanical traction is associated with fewer surgical interventions compared to care as usual in CTS patients. Reductions in patient-reported symptoms at 6 months' follow-up was similar in both groups. The long-term effects of mechanical traction require further evaluation.

Abstract
This paper presents the development of wrist ROM measurement system that was implemented on a rehabilitation glove for paretic hand, Easy-Flex, using a rotary potentiometer. This approach enables the device to measure the angles of up to 80° with the approximate resolution of 0.1°. The method along with a universal goniometer and a smartphone clinometer application were tested on 17 healthy participants in terms of reliability. The three instruments were able to accurately measure three different angles (flexion: -10°, neutral: 0°, and extension: 20°) with measurement errors less than 2°. Moreover, ICCs of the proposed method were close to 0.90 indicating the method implemented on Easy-Flex is reliable for measuring wrist flexion and extension measurement.

Abstract
Stroke affects multiple joints in the arm with stereotypical patterns of arm deformity involving the shoulder, elbow, wrist, and hand and with disrupted coordination of multiple joints in active movements. However, there is a lack of systematic methods to evaluate multi-joints and multi-degree of freedoms (DOF) neuro-mechanical changes, especially for complex systems with three or more joints/DOFs involved. This paper used a novel systematic method to characterize dynamics and control of the shoulder, elbow, and wrist of the human arm individually and simultaneously, including the couplings across the multiple joints during controlled movements. A novel method was developed to decompose the complex system into manageable single-joint level for more reliable characterizations. The method was used in clinical studies to characterize the multi-joint changes associated with spastic impaired arm of 11 patients post stroke and 12 healthy controls. It was found that stroke survivors showed not only increased stiffness at the individual joints locally but also significantly higher couplings across the joints. The relative increases in couplings are often higher than that of the local joint stiffness. The multi-joint characterization provided a tool to characterize impairment of individual patients, which would allow more focused impairment-specific treatment. In general, the decomposition method can be used for even more complex systems, making characterization of intractable system dynamics of three or more joints/DOFs manageable.

Abstract
Lofstrand, or forearm, crutches are a common assistive mobility device for those with functional impairments. However, repeated loading of the wrist and palmar region and continual hyperextension of the wrist during Lofstrand crutch usage may cause wrist strain, pain, and secondary injuries such as carpal tunnel syndrome. In order to reduce risk of injury, a novel wrist orthosis was developed with the intent of improving wrist posture and reducing/redirecting palmar loads from the carpal tunnel region to the adductor pollicis area. Dominant-hand palmar loads and wrist extension angles of 10 healthy, able-bodied subjects were measured during swing-through Lofstrand crutch-assisted gait to demonstrate the orthosis effectiveness. Each subject performed 10 trials each with and without the orthosis. An enhanced understanding of the effects of the wrist orthosis on kinematics and palmar loading was gained through this study. Results indicated a significant decrease in maximum palmar force, contact area, and wrist extension when using the orthosis. Palmar loads were observed to be redirected toward the adductor pollicis when using an orthosis during Lofstrand crutch-assisted gait. Ultimately, this device was effective in redistributing palmar loads with the potential to reduce pain and risk of carpal tunnel syndrome in long-term Lofstrand crutch users.

Abstract
We prospectively measured hand and wrist function in rheumatoid patients undergoing excision of the distal ulna. Range of motion, visual analogue pain scores and grip strength were measured in 22 wrists, and the Jebsen hand function test was administered to seven patients, preoperatively and at 3 and 12 months. At 1 year there were improvements in forearm pronation ( P = 0.04), supination ( P = 0.03) and wrist extension ( P = 0.02), but a reduction in flexion ( P = 0.009). Active radial deviation was reduced and ulnar deviation increased. There was a significant improvement in grip strength ( P = 0.05) and reduction in wrist pain ( P = < 0.0001). At 1 year the Jebsen hand function test showed improvements in simulated feeding, stacking checkers, and lifting large empty cans. Excision of the distal ulna in rheumatoid patients results in an improvement in some aspects of hand function.

Abstract
This in vitro study evaluated the performance of an ulnar head replacement. A joint simulator was employed that produced active forearm rotation in cadaveric specimens, with motion measured using an electromagnetic tracking system. The kinematics of the intact forearm were compared with a partial ulnar head replacement and a full replacement (with and without soft-tissue reconstruction) and a full excision of the ulnar head. There were no differences between intact kinematics and those following prosthetic reconstruction. However, ulnar head excision produced distal radioulnar joint instability in the form of radioulnar convergence and increased anteroposterior translations.

Abstract
We studied the changes in the shape of the triangular fibrocatilage (TFC: disc proper) which occur during forearm rotation in disarticulated and articulated wrists. The influence of artificial 3 mm ulnar lengthening on distortion of the disc was also examined. In the disarticulated wrists, slight distortion of the central and radial portions of the TFC was observed in the ulnar neutral variance specimens. More distortion was noted in the radial and central portions of the TFC in specimens with positive ulnar variance or with the ulna lengthened. However, in the articulated wrist, the TFC demonstrated little change in shape during pronosupination even in the ulnar positive variance wrists or with the ulna lengthened. There was no significant change in palmar and dorsal peripheral lengths of the TFC in ulnar neutral, ulnar positive or ulna-lengthened specimens at three rotatory positions of the forearm. These findings suggest that changes in ulnar variance which occur during forearm rotation can produce distortion on the TFC, but the carpus helps to maintain the shape of the TFC during pronation–supination, even with positive ulnar variance.

Abstract
Total wrist arthroplasty (TWA), first performed in the late 19th Century, is still an infrequently used operation. It is most commonly indicated in patients with rheumatoid arthritis who have pan-carpal wrist involvement. It is an alternative to total wrist arthrodesis in patients who wish to preserve joint motion. Patients must lead a low-demand lifestyle and have failed non-operative measures. Complications are not insignificant and have been reported to be as high as 43%. Modern generation implants most often fail due to dislocation or loosening. Because wrist arthrodesis remains the gold standard treatment, particularly in patients with higher physical demands, it remains to be seen whether TWA will gain greater acceptance as prosthetic designs evolve.

Abstract
OBJECTIVES This study assessed the effect of practicing the accordion on pain and posture of children and adolescent students. METHODS Pain and posture (forward head posture, scapular posture, and lumbar lordosis) were compared between two groups of preparatory and secondary school students, matched for age and sex: those who took accordion lessons (accordionists, n=16) and those who never studied a musical instrument (non-musicians, n=16). RESULTS Students taking accordion lessons reported significantly more pain in the shoulder, wrist/hand, and thoracic regions (p<0.05), showed significantly more forward head posture (accordionists, median ± interquartile distance [IQ] distance = 35.6° ± 7.8°; non-musicians = 45.3° ± 10.8°; p<0.05), and significantly increased lumbar lordosis (accordionists, median ± IQ distance = 55.5° ± 30.6°; nonmusicians = 39.0° ± 3.9°; p<0.05). No significant differences were found for scapular posture between groups. CONCLUSIONS This study suggests that children and adolescents who play the accordion have an increased forward head posture and lumbar lordosis and a tendency to report more pain than children and adolescents who do not play a musical instrument. Results corroborate the need for including healthy preventive teaching-learning strategies at music conservatoires.

Abstract
PURPOSE A giant cell tumor (GCT) of bone presenting in the distal radius is rare, however, when they occur, Campanacci Grade III tumors can present formidable reconstructive challenges. They are associated with a high local recurrence rate with intralesional treatment, therefore approaches to reconstruct the wrist after en bloc resection warrant study. QUESTIONS We asked: (1) What are the functional outcomes after en bloc resection and reconstruction of the wrist with a unipolar prosthesis in patients with Grade III GCT of the distal radius? (2) What complications occur with use of a unipolar prosthesis in these patients? (3) What are the oncologic outcomes with using en bloc resection and reconstruction with a custom unipolar wrist hemiarthroplasty for Grade III GCTs of the distal radius? METHODS We retrospectively analyzed 10 patients with Campanacci Grade III GCTs of the distal radius treated by a unipolar prosthesis after wide resection of the tumor between January 2008 and October 2013. During that period, all patients at our medical group who presented with a Grade III GCT of the distal radius were treated with wide resection and reconstruction using a custom unipolar implant. Pre- and postoperative pain at rest were assessed according to a 10-cm VAS score. The functional outcomes of the wrist were assessed using the modified Mayo wrist score, and the degenerative changes were evaluated radiographically by a new rating system based on the Knirk and Jupiter scale. We also analyzed tumor recurrence, metastases, and complications associated with the reconstruction procedure. All patients were available for followup at a mean of 52 months (range, 24-90 months). RESULTS Although the complication rate associated with prosthetic arthroplasty was relatively high (six of 10), none of our patients experienced severe complications. Two patients reported having occasional pain of the involved wrist at the time of final followup (VAS, preoperative versus postoperative: 0 versus 3; 5 versus 2, respectively). The mean modified Mayo wrist score was 68 (range, 45-90). Degenerative changes were found in three wrists (Grade 1, two patients; Grade 2, one patient). Aseptic loosening occurred in one patient and wrist subluxation occurred in two patients. Lung metastases or local tumor recurrence were not observed. CONCLUSIONS Because of the proportion of patients who had complications and progressive degeneration with this approach, we recommend first exploring alternatives to reconstruction with custom unipolar wrist hemiarthroplasty after resection of Grade III GCTs of the distal radius, such as fibular autografting. However, this technique provides an alternative for patients with concerns regarding possible morbidity associated with autografting, and for situations when allograft is not available.

Abstract
BACKGROUND Challenges with any therapeutic program for children include the level of the child's engagement or adherence. Capitalizing on one of the primary learning avenues of children, play, the approach described in this article is to develop therapeutic toy and game controllers that require specific and repetitive joint movements to trigger toy/game activation. OBJECTIVE The goal of this study was to evaluate a specially designed wrist flexion and extension play controller in a cohort of children with upper extremity motor impairments (UEMIs). The aim was to understand the relationship among controller play activity, measures of wrist and forearm range of motion (ROM) and spasticity, and ratings of fun and difficulty. DESIGN This was a cross-sectional study of 21 children (12 male, 9 female; 4-12 years of age) with UEMIs. METHODS All children participated in a structured in-clinic play session during which measurements of spasticity and ROM were collected. The children were fitted with the controller and played with 2 toys and 2 computer games for 5 minutes each. Wrist flexion and extension motion during play was recorded and analyzed. In addition, children rated the fun and difficulty of play. RESULTS Flexion and extension goal movements were repeatedly achieved by children during the play session at an average frequency of 0.27 Hz. At this frequency, 15 minutes of play per day would result in approximately 1,700 targeted joint motions per week. Play activity was associated with ROM measures, specifically supination, but toy perception ratings of enjoyment and difficulty were not correlated with clinical measures. LIMITATIONS The reported results may not be representative of children with more severe UEMIs. CONCLUSIONS These outcomes indicate that the therapeutic controllers elicited repetitive goal movements and were adaptable, enjoyable, and challenging for children of varying ages and UEMIs.

Abstract
Distal radius malunion is a problem that is common to distal radius fractures and can affect the contact mechanics of the distal radioulnar joint (DRUJ). The goal of this study was to use a computational model of the DRUJ to investigate the influence distal radius orientation has on its contact mechanics. Detailed, finite element models of the radius and ulna bones were constructed from magnetic resonance imaging data. The orientation of the distal radius was rotated in 2° increments about three orthogonal axes representing dorsal-palmar rotation, radial-ulnar rotation and anteversion-retroversion. A computational model was used to predict joint contact at the DRUJ in each condition. Joint contact was found to be most sensitive to dorsal rotation of the distal radius, while radial and ulnar rotation did not substantially affect joint contact pressure. Slight retroversion was found to lower joint contact pressure. In most cases, more than 6° rotation in a given direction resulted in dislocation of the DRUJ, so that adaptation at the joint would be required to maintain articular contact. The joint contact model implemented in this study allowed the relationship between distal radius orientation and DRUJ contact to be examined systematically, in a way that is difficult to achieve using a cadaver-based approach. The results demonstrated the distal radius displacements most critical for maintaining healthy joint mechanics at the DRUJ. It is important that clinicians consider the influence of distal radius malunion and its treatment on DRUJ mechanics, in addition to its consequences for wrist function and forearm rotation.

Abstract
The current study investigated the incidence of complications after surgery for distal radial fractures. This multicenter retrospective study was conducted at 11 institutions. A total of 824 patients who had distal radius fractures that were treated surgically between January 2010 and August 2012 were identified. The study patients were older than 18 years and were observed for at least 12 weeks after surgery for distal radius fractures with a volar locking plate. Sex, age, fracture type according to AO classification, implants, wrist range of motion, grip strength, fracture consolidation rate, and complications were studied. Analysis included 694 patients, including 529 women and 165 men, with a mean age of 64 years. The mean follow-up period was 27 weeks. The fracture consolidation rate was 100%. There were 52 complications (7.5%), including 18 cases of carpal tunnel syndrome, 12 cases of peripheral nerve palsy, 8 cases of trigger digit, 4 cases of tendon rupture (none of the flexor pollicis longus), and 10 others. There was no rupture of the flexor pollicis longus tendon because careful attention was paid to the relationship between the implant and the tendon. Peripheral nerve palsy may have been caused by intraoperative traction in 7 cases, temporary fixation by percutaneous Kirschner wires in 3 cases, and axillary nerve block in 1 case; 1 case appeared to be idiopathic. Tendon ruptures were mainly caused by mechanical stress. [Orthopedics.2016; 39(5):e893-e896.].

Abstract
Forty patients (mean age, 37 years) with intraarticular C2 and C3 Colles fractures were treated by open reduction, internal fixation and bone grafting. At a mean follow-up of 8 years radiocarpal and midcarpal motion was evaluated, the depth of the articular surface of the distal radius in the sagittal plane was measured and the presence of arthritis was noted. The fractures healed with a mean palmar tilt of 6°, a mean ulnar tilt of 18° and ulna variance within 1 mm of the contralateral side. The depth of the articular surface of the distal radius was 1.3 mm greater than the uninvolved side. Measurement of carpal bone angles relative to the radius in maximum flexion and extension revealed lunate extension of 23°, lunate flexion of 15°, capitate extension of 62°, capitate flexion of 40°. There was a significant correlation between articular surface depth and radiocarpal motion.

Abstract
Wrist injuries in the gymnast are due to the transformation of the upper extremity into a weight bearing entity. Gymnast wrist pain presents a difficult diagnostic and therapeutic challenge. Here, we present a new case of extensor tendon impingement in an elite gymnast. To our knowledge, there is no similar report in the literature.

Abstract
Nine cases of failed biaxial wrist replacement underwent revision surgery and subsequent clinical and radiographic assessment at a mean follow-up of 28 months. Clinical assessment included the hospital for special surgery (HSS) and activities of daily living scoring systems. Five patients had a revision biaxial wrist replacement, three had wrist fusions and two underwent an excision arthroplasty. The mean HSS score was 73 for the revision biaxial replacements, 63 for the wrist fusions and 92 for the excision arthroplasties. The mean activities for daily living score was 16 for the revision biaxial replacements, 14 for the wrist fusion and 20 for the excision arthroplasties. Despite the experience of implant failure, six patients would still choose a primary wrist replacement again. All patients in this small series appear to have had good clinical outcomes. Revision to another wrist replacement appears no worse than a wrist fusion in the short term and patients value the preservation of movement that an implant offers.

Abstract
Between 1993 and 2002, 108 patients with isolated and persisting radial nerve palsy, underwent transfer of the flexor carpi ulnaris tendon alone to extensor digitorum communis, extensor indicis proprius and extensor pollicis longus. Only patients with sufficient flexor carpi ulnaris muscle power (grade M5) underwent this procedure. Long-term functional results were reviewed at a mean postoperative follow up of 48 (range 3–120) months. In comparison with the contralateral hand, the range of extension of the wrist was less but extension of the fingers and the MCP joints were similar to that of the normal hand. All patients improved functionally and could cope with their routine activities. Most were able to return to their previous jobs. There was no obvious difference in the end result of using this single transfer from our previous results using the three tendon transfers which are commonly used to treat radial nerve palsy. The single flexor carpi ulnaris tendon transfer has some advantages in terms of simplicity, shorter operation time, less morbidity and less surgical scars.

Abstract
This retrospective study evaluates the surgical treatment of a group of patients with unknown chronic dorsal wrist pain. The cause of their symptoms was interpreted as a painful entrapment of fibrous tissue in the radio-carpal and inter-carpal joints during specific movements. Between 1997 and 2001, 30 patients were treated by surgical excision of this tissue and 26 patients were traced for follow-up. Twenty-three patients were symptom free, or experienced major benefit from surgery. Wrist function measurements using the VAS scale showed improvement in 24 patients. Microscopic examination of the removed specimen shows fibrous tissue with non-specific changes. Inter-carpal soft tissue entrapment can explain the typical clinical findings in some patients with unknown chronic dorsal wrist pain. After careful selection, surgical excision of all entrapped tissue in the radio-carpal and mid-carpal joint may give relief of pain and improvement of wrist function.

Abstract
The purpose of this clinical study was to compare patients’ symptoms and radioulnar convergence following distal radioulnar reconstruction with and without a functional brace on. Standardized radiographs were taken of the involved wrist at rest, while holding a weight, and during maximum power grip. All radiographs were then repeated while wearing a prefabricated functional brace (Maramed, Miami, FL). The functional brace did not decrease radioulnar convergence and, at rest, the brace actually increased radioulnar convergence. Despite this, all patients who experienced pain without the brace were pain free with the brace on. We conclude that forearm bracing may be a useful nonoperative treatment for residual pain following DRUJ salvage surgery, though its mechanism of action is unclear.

Abstract
Tendon transfers are frequently needed to improve hand function in obstetric brachial plexus injuries. The reconstruction cannot always be achieved using local donor transfers in the forearm as these are not always available. In such cases, we propose the use of the brachialis muscle as a useful donor for transfer. Five adolescents with obstetric brachial plexus palsy were operated on to reconstruct wrist extension and/or pronation using the brachialis muscle transfer to the pronator teres ( n = 1) extensor carpi radialis brevis ( n = 1) and extensor carpi radialis longus ( n = 3). Twelve months after surgery, average active motion recovery was 20° for wrist extension and 14° for pronation. Active and passive range of motion was similar.

Abstract
Patients with poststroke complex regional pain syndrome (CRPS) show different symptoms compared to other types of CRPS, as they usually complain of shoulder and wrist pain with the elbow relatively spared. It is thus also known by the term "shoulder-hand syndrome."The aim of this study is to present a possible pathophysiology of poststroke CRPS through ultrasonographic observation of the affected wrist before and after steroid injection at the extensor digitorum communis (EDC) tendon in patients suspected with poststroke CRPS.Prospective evaluation and observation, the STROBE guideline checklist was used.Twenty-three patients diagnosed as poststroke CRPS in accordance to clinical criteria were enrolled. They had a Three Phase Bone Scan (TPBS) done and the cross-sectional area (CSA) of EDC tendon was measured by using ultrasonography. They were then injected with steroid at the EDC tendon. The CSA of EDC tendon, visual analogue scale (VAS), and degree of swelling of the wrist were followed up 1 week after the injection.TPBS was interpreted as normal for 4 patients, suspected CRPS for 10 patients, and CRPS for 9 patients. Ultrasonographic findings of the affected wrist included swelling of the EDC tendon. After the injection of steroid to the wrist, CSA and swelling of the affected wrist compared to that before the treatment was significantly decreased (P < 0.001). The VAS score declined significantly after the injection (P < 0.001).Our results suggest that the pathophysiology of poststroke CRPS might be the combination of frozen shoulder or rotator cuff tear of shoulder and soft tissue injury of the wrist caused by the hemiplegic nature of patients with stroke.

Abstract
The use of awkward wrist postures and unskilled techniques might induce lateral epicondylitis. This study thus investigated the effects of wrist deviation combined with extension and movement velocity on the dynamic performances of the wrist muscles during the coupling posture via a custom-made bi-planar isokinetic dynamometer. Thirty subjects were recruited to perform the isokinetic testing. We measured the muscle strengths and activities for the wrist extensors and flexors during concentric and eccentric contractions at three movement velocities, 30°s-1, 90°s-1, and 180°s-1, combined with three wrist postures, neutral position (NP), radial deviation (RD), and ulnar deviation (UD). The root mean square (RMS) of the electromyographic signal in the extensor digitorum communis (EDC), normalized peak torque of extensors, and ratio of normalized peak torque between wrist extensors and flexors, were all greater in the NP than RD and UD in both contractions. The ratio of RMS between EDC and flexor digitorum superficialis (FDS) had a significantly greater value in RD than UD during the concentric contraction. The EDC showed significantly higher activity at the fast velocity in both contractions. Nevertheless, a significantly higher RMS of the electromyographic signal between EDC and FDS and the ratio of strength between wrist extensors and flexors were found at slow velocity in both contractions. The wrist deviation combined with extension and movement velocity of the wrist joint should thus be considered as influential factors which might alter the dynamic performances, and may result in further injury of the elbow joint.

Abstract
Complex distal intra-articular radial fractures (AO Type C3) are rare, but are life-changing injuries. They are usually related to high-velocity trauma mechanisms in a working male population.We surveyed a cohort of these fractures treated in our institution to assess the functional long-term outcome.Twelve consecutive patients with comminuted intra-articular distal radial fractures were treated at our institution. Osteosynthesis was performed by a single senior surgeon with volar and dorsal extended approaches. The intermediate and final control included conventional X-ray, range of motion (ROM), grip strength, and the Disabilities of the Arm, Shoulder, and Hand index (DASH), as well as the Patient-rated Wrist Evaluation (PRWE) score for functional outcome at 1 and 10 years' of follow-up.At 10 years' follow-up, anatomic reconstruction with a step or gap of <1 mm was achieved in 10 of the 12 above-mentioned patients, whereas 2 patients were lost to follow-up. ROM was good to excellent in 8 patients. Median grip strength was 107% of the contralateral side. Median DASH-Index and PRWE were 2.3 and 6 respectively, at 10 years. Eight patients returned to premorbid heavy labor. One patient was retired at the time of injury.Combined volar and dorsal approaches allow achieving anatomical reconstruction in comminuted intra-articular distal radius fractures and reveal good functional outcomes at intermediate and long-time follow-up.

Abstract
INTRODUCTION Whilst initial closed reduction followed by definitive open fixation is widely applied in the treatment of distal radial fractures, the effect of the closed reduction on the reconstruction of the articular surface remains unclear. Our research questions were: METHODS Palmar tilt and radiocarpal inclination of 425 patients were measured at admission, following initial closed reduction and after surgical reconstruction. RESULTS Closed reduction increased palmar tilt by 12.1° and radial inclination by 2.7°. Open surgical reduction further corrected palmar tilt by 17.88° and radial inclination by 3.5°. Whilst there was no association between postoperative palmar tilt and initially achieved closed reduction, a significant association between radial inclination following closed reduction and surgical fixation was found. CONCLUSION Our retrospective study challenges the existence of a relationship between the initial closed reduction and the reconstruction of the anatomic joint line in surgically treated distal radial fractures.

Abstract
The tuberculosis of the hand and the wrist is a rare entity. Affecting the scapholunate joint is exceptional. It is usually diagnosed at an advanced stage of carpal destruction, due to slowly development of the symptoms. We report the case of a 58-year-old female, presenting as wrist pain for 3 months. Clinical study showed a local swelling in the left wrist, the mobility of the wrist was normal but painful at the end of motion. The diagnosis of osteoarticular tuberculosis was suspected after radiological and biological study then confirmed after histological study. Antibacillary chemotherapy during 12 months promoted healing and good outcome.

Abstract
PURPOSE To identify the varying contributions of the proximal and distal portions of the subsheath of the extensor carpi ulnaris (ECU) to its stability, evaluate the correlation of ulnar groove depth and ECU subluxation, and observe the effect of forearm and wrist positions on ECU stability. METHODS Extensor carpi ulnaris tendon position relative to the ulnar groove was measured in 10 human cadaveric specimens with the subsheath intact, partially sectioned (randomized to distal or proximal half), and fully sectioned. Measurements were obtained in 9 positions: forearm supinated, neutral, and pronated and wrist extended, neutral, and flexed. Ulnar groove depth was measured on all specimens. RESULTS In 7 of 10 specimens with an intact subsheath, the ECU tendon subluxated out of the groove in at least 1 forearm-wrist position. We noted the subluxation of the ECU tendon in all wrist-forearm positions with the exception of pronation-extension in at least 1 specimen. For partial subsheath sectioning, tendon displacement markedly increased after distal subsheath sectioning but not after proximal sectioning. For full subsheath sectioning, wrist flexion produced subluxation in all forearm positions, and forearm supination produced subluxation in all wrist positions. Maximum displacement occurred in supination-flexion. There was no correlation between ulnar groove depth and ECU subluxation. CONCLUSIONS Mild tendon subluxation occurred in the intact specimens in most tested positions. Two positions were remarkable for their consistency in maintaining the tendon within the groove: pronation-neutral and pronation-extension. In fully sectioned specimens, the greatest subluxation occurred in supination-flexion, with supination and flexion independently producing subluxation. Partial sectioning demonstrated that the distal portion of the subsheath played a more important role than the proximal portion in stabilizing the ECU. CLINICAL RELEVANCE Subsheath repair or reconstruction should target the distal portion of the subsheath. During postinjury rehabilitation or following surgical reconstruction, combined forearm supination and wrist flexion should be avoided.

Abstract
UNLABELLED The relationship between periarticular osteoporosis in the distal forearm and joint destruction or functional impairment in patients with rheumatoid arthritis (RA) is not sufficiently elucidated. From a single institutional cohort study, we found a strong correlation between periarticular forearm bone mineral density (BMD) and joint destruction or functional impairment. INTRODUCTION This study was conducted to investigate (1) the difference between various periarticular regions of interest (ROIs) of BMD of the forearm, (2) the correlation between periarticular forearm BMD and joint destruction and physical function, (3) the independent variables for predicting BMD of the forearm, and (4) the forearm BMD of different ROIs in the early stage of RA. METHODS We conducted a cross-sectional study in an RA cohort. Measurements included BMD of the distal forearm, joint destruction of the hands assessed by modified total Sharp score (mTSS), functional impairment assessed by a health assessment questionnaire (HAQ), and other clinical data. Variables affecting the forearm BMD values were analyzed by correlation and stepwise regression analyses. RESULTS Of the 405 patients enrolled in the present study, 370 (average age; 62.9 years) were identified as having definite RA with a complete set of data. BMD in the distal end of the forearm (BMDud) was significantly reduced compared with that in the distal third of the forearm (BMD1/3). In a stepwise regression analysis, the mTSS in BMD1/3 was an independent predicting variable, while age and partial HAQ scores associated with the upper extremity were common independent variables in BMDud and BMD1/3. BMDud was significantly less than BMD1/3, even in patients with a short duration of the disease. BMD1/3 was significantly less in non-remission group compared with that in remission group in patients with a short duration of the disease. CONCLUSION Periarticular BMD in the distal forearm is closely correlated with joint destruction and functional impairment in RA. Periarticular BMD in the distal forearm may be already reduced at the clinical manifestation of the disease.

Abstract
Parkinson's Disease (PD) patients often need Deep Brain Stimulation (DBS) surgery when they become intolerant to drugs or these lose efficiency. A stimulation electrode is implanted in the basal ganglia to promote the functional control of the deregulated dopaminergic motor pathways. The stimulation target is defined by medical imaging, followed by electrophysiological inspection for fine electrode position trimming and electrical stimulation tuning. Intra-operative stimulation of the target and the evaluation of wrist rigidity allows to choose the stimulation parameters which best alleviate PD symptoms without side effects. Neurologists impose a passive wrist flexion movement and qualitatively describe the perceived decrease in rigidity under different voltages, based on its experience and with subjectivity. We designed a novel, comfortable and wireless wearable motion sensor to classify the wrist rigidity by deriving a robust signal descriptor from angular speed values and a polynomial mathematical model to classify signals using a quantitative continuous scale. The descriptor significantly (p<0.05) distinguished between non-rigid and rigid states, and the classification model labelled correctly 83.9% of the evaluated signals against the blind-agreement of two specialists. Additionally, we developed a methodology to detect cogwheel rigidity from the angular speed signal with high sensitivity (0.93). Our system provides a reliable evaluation of wrist rigidity, improving upon the inherent subjective clinical evaluation while using small, simple and easy to use motion sensor.

Abstract
Human grasping and manipulation control critically depends on tactile feedback. Without this feedback, the ability for fine control of a prosthesis is limited in upper limb amputees. Although various approaches have been investigated in the past, at present there is no commercially available device able to restore tactile feedback in upper limb amputees. Based on the Discrete Event-driven Sensory feedback Control (DESC) policy we present a device able to deliver short-lasting vibrotactile feedback to transradial amputees using commercially available myoelectric hands. The device (DESC-glove) comprises sensorized thimbles to be placed on the prosthesis digits, a battery-powered electronic board, and vibrating units embedded in an arm-cuff being transiently activated when the prosthesis makes and breaks contact with objects. The consequences of using the DESC-glove were evaluated in a longitudinal study. Five transradial amputees were equipped with the device for one month at home. Through a simple test proposed here for the first time-the virtual eggs test-we demonstrate the effectiveness of the device for prosthetic control in daily life conditions. In the future the device could be easily exploited as an add-on to complement myoelectric prostheses or even embedded in prosthetic sockets to enhance their control by upper limb amputees.

PURPOSE To examine the effect of volar angulation deformities of the distal radius with and without triangular fibrocartilage complex (TFCC) rupture on forearm range of motion and the kinematics of the ulnar head at the distal radioulnar joint (DRUJ) during simulated active forearm rotation. METHODS Volar angulation deformities of the distal radius with 10° and 20° angulation from the native orientation were created in 8 cadaveric specimens using an adjustable apparatus. Active supination and pronation were performed using a forearm motion simulator. Pronation and supination range of motion was quantified with each deformity. In addition, changes in the dorsovolar position of the ulnar head relative to the radius were calculated after simulating each distal radial deformity. Testing was performed with the TFCC intact and sectioned. RESULTS Volar angulation deformities of 20° decreased the supination range with preservation of pronation. There was no effect of TFCC status on the range of forearm rotation. With the TFCC intact, volar angulation deformities translated the ulna slightly dorsally in pronation and volarly in supination. After sectioning the TFCC, volar angulation deformities of 10° and 20° translated the ulna dorsally throughout forearm rotation. CONCLUSIONS Volar angulation deformities reduce supination range and alter the DRUJ kinematics. The increased tension in the intact TFCC caused by volar angulation deformities likely prevented the expected dorsovolar displacement at the DRUJ and restricted supination. Dividing the TFCC released the constraining effect on the DRUJ and allowed the ulna to translate dorsally. However, supination remained limited, presumably because of impediment from the dorsally subluxated ulna. CLINICAL RELEVANCE This study demonstrated the importance of correcting volar angulation deformities of the distal radius to less than 20° in order to maintain normal range of forearm rotation and to less than 10° to maintain normal DRUJ kinematics when the TFCC is ruptured.

Abstract
PURPOSE OF THE STUDY Treatment of distal radius fractures in elderly patients is controversial. This study explored the relationship between radiographic parameters and clinical outcomes of patients with distal radius fractures following conservative treatment. The study was done using radiographic measurements of distal radius fractures in elderly patients. PATIENTS AND METHODS Ninety-two active, healthy patients with conservatively managed distal radius fractures were included in the study. Functional and radiographic assessments were made 1 year after injury. Fifty patients who underwent corrective osteotomy comprised the control group. Radiographic parameters and clinical outcomes were compared between the two groups. The correlation coefficients of the radiographic parameters were analysed using multiple regression. RESULT Radius height (RH), volar tilt (VT) and Mayo wrist and Disabilities of the Arm, Shoulder and Hand (DASH) scores in the experimental group were significantly superior to those of the control group. There was no significant group difference in radial inclination. Multiple regression analysis revealed that the most important factor affecting functional outcome was RH, followed by VT. DISCUSSION RH and VT were significantly correlated with the clinical outcomes of conservative treatment of distal radius fractures. RH should be given foremost consideration in elderly patients. Preoperatively, surgeons should evaluate this parameter carefully and be prepared to treat injuries accordingly. LEVEL OF EVIDENCE Level IV retrospective study.
