RESUMO
PURPOSE: This study aimed to present the clinical outcomes of the dorsal plating technique for palmar fracture dislocations of the proximal interphalangeal (PIP) joint. This plating technique minimizes dissection and interference with the finger extensor mechanism. METHODS: We treated seven patients (with a mean age of 39.1 years) with dorsal hook plates for palmar fracture dislocations of the PIP joint between April 2018 and August 2022. The little finger was affected in five patients, and ring finger was affected in two. The mean time to surgery was 5.6 days, and the postoperative follow-up period was seven months. On the second postoperative day, all patients were allowed active motion of both the PIP and the distal interphalangeal (DIP) joints. Simultaneously, DIP blocking exercises were started to prevent adhesion of the extensor mechanism. RESULTS: The mean active flexion and extension of the PIP joint was 105° and -4°, respectively, whereas those of the DIP joint were 65° and 4°. No patient experienced extension lag in the DIP joint. The mean total active motion (TAM) was 273°, and the %TAM was 96%. The grip strength of the affected hand averaged 90% of that of the unaffected hand. The mean numerical rating scale for pain was 0.3 points, and the mean Hand20 score was 5.1 points. No complications were observed; two patients underwent implant removal at their request. CONCLUSIONS: The present study suggests that this hook plate technique, which minimizes interference with the finger extension mechanism, is an effective surgical procedure that allows patients to tolerate early range of motion exercises and obtain satisfactory clinical outcomes in both the PIP and DIP joints. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.
RESUMO
BACKGROUND: Ulnar shortening osteotomy (USO), as its name implies, is used to shorten the ulna. It subsequently tightens the triangular fibrocartilage complex (TFCC) and ulnar wrist. TFCC foveal insertion is a primary stabilizer of the distal radioulnar joint. It is unclear whether USO is effective in TFCC foveal injuries. The purpose of this study was to review the clinical outcomes of ulnar shortening osteotomies with and without TFCC foveal injuries. METHODS: We retrospectively reviewed patients with ulnar wrist pain treated with USO and wrist arthroscopy including the distal radioulnar joint (DRUJ). Sixty-five patients were included in this study. An algorithm was used to guide surgical decision-making. After arthroscopic confirmation of ulnar impaction syndrome, we performed USO with a locking compression plate (mean length of shortening, 2.7 mm; range, 1-7.5 mm). The flattened TFCC disc due to ulnar shortening was confirmed arthroscopically. If the DRUJ was unstable after USO, we repaired the TFCC foveal insertion. RESULTS: There were 32 post-traumatic and 33 idiopathic cases. We detected TFCC disc injuries in 34 wrists and TFCC foveal injuries in 33 wrists; both types were found in 15 wrists. TFCC foveal injuries were not significantly correlated with patient age, history of trauma, or clinical outcome. Most patients showed good clinical outcomes; 31 of 65 patients had preoperative DRUJ instability, with a significant number having foveal but not disc injuries. CONCLUSION: USO achieved reasonable outcomes, even in patients with TFCC foveal injuries. In cases demonstrating ulnar impaction, USO should be prioritized over TFCC repair.

BACKGROUND: Most surgeons are unaware that idiopathic neuropathy, which occurs independently of mechanical injury, can present as postoperative peripheral neuropathy. The aim of this study was to reveal the presence of postoperative neuropathy considered to be induced by surgical stress and to make surgeons aware that idiopathic neuropathy can occur postoperatively. METHODS: We conducted a survey among orthopedic surgeons regarding patients with postoperative neuropathies of unknown cause. For each case, the type of neuropathy, preceding surgery and anesthesia, patient background, clinical findings, and clinical course were investigated. RESULTS: Seven patients were identified. The mean time from surgery to the onset of neuropathy was 9.3 days (range 1-15 days). Five of the patients fully recovered spontaneously within 1 year, while the remaining two underwent neurolysis. One patient presented with hourglass-like constrictions in the radial nerve. No inflammatory cells were found in the epineurium of the affected nerve. CONCLUSIONS: Although it is rare, postoperative idiopathic neuropathy occurs in clinical practice, and it is crucial that surgeons recognize the existence of this neuropathy to elucidate its pathogenesis as well as to reduce the risk of litigation.

BACKGROUND: The guidelines presented herein provide recommendations for the management of patients with lateral epicondylitis of the humerus. These recommendations are endorsed by the Japanese Orthopaedic Association (JOA) and Japan Elbow Society. METHODS: The JOA lateral epicondylitis guideline committee revised the previous guidelines on the basis of the "Medical Information Network Distribution Service Handbook for Clinical Practice Guideline Development 2014", which emphasized the importance of the balance between benefit and harm, and proposed a desirable method for preparing clinical guidelines in Japan. These guidelines consist of 11 clinical questions (CQs), 9 background questions (BQs), and 3 future research questions (FRQs). For each CQ, outcomes from the literature were collected and evaluated systematically according to the adopted study design. RESULTS: The committee proposed recommendations for each CQ by determining the level of evidence and assessing the consensus rate. Physical therapy was the best recommendation with the best evidence. The BQs and FRQs were answered by collecting evidence based on the literature. CONCLUSIONS: The guidelines presented herein were reviewed systematically, and recommendations were proposed for each CQ. These guidelines are expected to be widely used not only by surgeons or physicians but also by other healthcare providers, such as nurses, therapists, and athletic trainers.

BACKGROUND: Iatrogenic nerve injuries can result from surgical damage. Thus, physicians should be aware of the risk factors and procedures that need to be followed in such patients. The purpose of this study was to examine data pertaining to patients with known iatrogenic nerve injuries and to elucidate the detailed causes of these injuries, the affected nerves, and the type of surgical procedures for treatment. METHODS: This retrospective study included 232 consecutive patients who underwent surgical treatment for peripheral nerve palsy or nerve injury between 2006 and 2017 at our hospital. Among the 232 patients investigated, we identified 51 cases with iatrogenic nerve injuries (23 women and 28 men; mean age, 51.3 years). Among the 51 patients, 45 were referred from other hospitals, and the remaining were from our hospital. Data were summarized using descriptive statistics. RESULTS: Direct surgical damage occurred in 94% (48/51) of patients with iatrogenic nerve injuries. Such injuries mostly developed after surgery for bone fractures (33%), resection of soft tissue tumors (22%), and carpal tunnel release procedures (20%). The nerves most commonly affected in such procedures are the radial nerve (26%), median nerve (24%), and ulnar nerve (17%). The median interval of referral to our hospital after nerve injury was 5.1 months. The median interval of surgery to correct the injury was 7 months. Surgeries to correct iatrogenic nerve injuries performed at our hospital included neurolysis (55%), nerve grafts (29%), direct suture procedures (10%), and tendon transfers (6%). CONCLUSIONS: We believe that wide dissemination of the results obtained in this study will reduce the incidence of iatrogenic peripheral nerve injuries and increase the speed of referrals to specialized centers.

INTRODUCTION: In this study we aimed to clarify the association between interleukin-6 (IL-6) secretion in fibroblasts in carpal tunnel syndrome (CTS) patients and their biophysical parameters, including association with trigger finger and whether tranilast inhibits IL-6 secretion in fibroblasts. METHODS: Fibroblasts were obtained from tenosynovial tissue harvested from idiopathic CTS patients undergoing carpal tunnel release and tenosynovectomy and cultured in media containing tranilast with or without tumor necrosis-α (TNF-α) or interleukin-1ß (IL-1ß). Their proliferation was evaluated and secreted IL-6 levels and IL-6 mRNA expression were quantified. Correlations between IL-6 concentration and patient characteristics were examined. RESULTS: IL-6 secretion was significantly associated with trigger finger (P = .001). Tranilast inhibited fibroblast proliferation in a dose-dependent manner and suppressed IL-6 secretion. DISCUSSION: IL-6 overproduction in tenosynovial tissue may account for the association between CTS and trigger finger. Future studies should investigate whether tranilast can be used to treat patients with CTS.

BACKGROUND: Hand osteoarthritis (OA) has a wide spectrum of clinical presentations and physical function is one of the core domains where patients suffer. The Functional Index for Hand Osteoarthritis (FIHOA) is a leading assessment tool for hand OA-related functional impairment. Our objective was to make a Japanese version of FIHOA (J-FIHOA) and validate it among Japanese hand OA patients. METHODS: Forward and backward translation processes were completed to create a culturally adapted J-FIHOA. A prospective, observational multicenter study was undertaken for the validation process. Seventeen collaborating hospitals recruited Japanese hand OA patients who met the American College of Rheumatology criteria. A medical record review and responses to the following patient-rated questionnaires were collected: J-FIHOA, Hand20, Health Assessment Questionnaire (HAQ), numerical rating scale for pain (NRS pain) and Short Form 36 Health Survey (SF-36). We explored the structure of J-FIHOA using factor analysis. Cronbach's alpha coefficients and item-total correlations were calculated. Correlations between J-FIHOA and other questionnaires were evaluated for construct validity. Participants in clinically stable conditions repeated J-FIHOA at a one- to two-week interval to assess test-retest reliability. To evaluate responsiveness, symptomatic patients who started new pharmacological treatments had a 1-month follow-up visit and completed the questionnaires twice. Effect size (ES) and standardized response mean (SRM) were calculated with pre- and post-treatment data sets. We assessed responsiveness, comparing ES and SRM of J-FIHOA with other questionnaires (construct approach). RESULTS: A total of 210 patients participated. J-FIHOA had unidimensional structure. Cronbach's alphas (0.914 among females and 0.929 among males) and item-total correlations (range, 0.508 to 0.881) revealed high internal consistency. Hand20, which measures upper extremity disability, was strongly correlated with J-FIHOA (r = 0.82) while the mental and role-social components of SF-36 showed no correlations (r = - 0.24 and - 0.26, respectively). Intraclass correlation coefficient for test-retest reliability was 0.83 and satisfactory. J-FIHOA showed the highest ES and SRM (- 0.68 and - 0.62, respectively) among all questionnaires, except for NRS pain. CONCLUSIONS: Our results showed J-FIHOA had good measurement properties to assess physical function in Japanese hand OA patients both for ambulatory follow-up in clinical practice, and clinical research and therapeutic trials.

BACKGROUND: Although some radiographic evaluations of the risk of flexor tendon injury following fixation of a distal radius fracture are useful, these radiographic measurements are limited because of their inability to obtain three-dimensional measurements. We hypothesized that CT-based measurements would be more sensitive indicators for risk estimation than radiography. METHODS: We retrospectively evaluated the relationship between plate positioning and the incidence of flexor tendon symptoms based on postoperative radiographic and CT-based measurements in 99 hands that were followed up for more than 12 months. We also compared the reproducibility, diagnostic accuracy, and ability to detect the plate-bone gap between radiographic and CT-based measurements. We also assessed the correlation between the volar prominence and plate-bone gap using CT. Multivariable analysis using stepwise logistic regression was performed to identify factors independently associated with tendon rupture or irritation. RESULTS: In single variable analysis, we found that the volar tilt was significantly smaller and the radiographic plate-to-critical line distance (PCL), CT-PCL, and CT-gap were significantly greater in the group with tendon irritation or rupture. Multivariable logistic regression analysis indicated that the CT-based measurement of the volar prominence is a significantly positive independent predictor of tendon rupture or irritation. CONCLUSION: CT-based measurement of the volar prominence may be one of the best radiographic predictors of the risk of flexor tendon injury following fixation of a distal radius fracture regardless of the plate type and distal prominence and the extent of rotation. This measurement may assist surgeons when deciding on the need for removal of hardware to decrease the long-term risk of flexor tendon rupture.

This multicenter cross-sectional study aimed to determine the differences in distribution and fracture pattern between low-energy and high-energy groups in distal humeral fractures in Japan. Retrospectively, 133 patients (48 males, 85 females) with distal humeral fractures were enrolled in this study. The age, sex, fracture classification, injury mechanism, preoperative therapy for osteoporosis, and nature of soft-tissue injury were recorded for all patients. The Mann-Whitney U test and chi-square test or Fisher's exact test were used for non-normally distributed variables and categorical variables, respectively, to compare differences between the two groups. The mean age of the patients at the time of surgery was 66 years (range 21-99 years). Marked differences were observed between the two groups in terms of age, sex, and fracture pattern. The mean age of patients with AO classification type A2 fractures was significantly higher than that of the patients with other fracture types. In contrast, the mean age of patients with AO classification type C2 fractures was slightly lower than that of the remainder of the population. In the low-energy trauma group, females accounted for 72.2% of fractures and their mean age at the time of surgery was 76 years. Low-energy trauma among elderly individuals was prominent.
RESUMO
The purpose of this study was to examine the occurrence rate of longitudinal cracks and associated characteristics following volar locking plate fixation of the distal radius. Using case records from Shizuoka Saiseikai General Hospital dated between March 2008 and March 2015, a total of 419 eligible adult patients were identified. Standard anteroposterior postoperative radiographs were evaluated to classify longitudinal crack occurrence. Documented variables were compared between patients with longitudinal cracking and those without. Univariate analyses were conducted among each plate group. There were 38 confirmed cases of cracking (Acu-Loc: n = 25, Acu- Loc 2: n = 11, VA-TCP: n = 2). All cracks healed within 4 to 6 weeks after the operation. Plate type, along with patient age and sex were significantly associated with the occurrence of a longitudinal crack (p < 0.05). Although no severe complications related to longitudinal cracking were observed, associated risks for specific patient groups should be considered.

Postoperative lymphedema is considered irreversible once it has developed, and significantly lowers the patient's quality of life. However, lymphatic function has recently been clarified, and it is possible that lymphedema can be cured if early treatment is started. This two-arm randomized clinical trial (UMIN000026124) will prospectively evaluate 24 patients with early-stage breast cancer-related lymphedema at the Nagoya University Hospital and Aichi Cancer Center Hospital. The eligibility criteria will be patients who are diagnosed with stage 0-1 breast cancer-related lymphedema, as defined by the International Society of Lymphology, within 12 weeks after breast cancer surgery. The diagnosis of lymphedema will be confirmed using a bioimpedance spectroscopy device (L-Dex®). Participants will be randomized 1:1 into the intervention and control groups. The physicians and patients will be aware of their group assignment, although treatment efficacy will be evaluated by raters who are blinded to the group assignments. The intervention group will complete grasping exercises in the Hand Incubator device for 4 weeks. The primary outcome will be the change in the affected upper limb's volume after the intervention, as measured using the water displacement method. This study may help establish a standard treatment for postoperative lymphedema.

OBJECTIVE: The aim of this study was to verify the use of initial plain radiographs, specifically the presence of a longitudinal crack on the olecranon, for diagnosing olecranon occult fractures in children. METHODS: We retrospectively reviewed all patients younger than 16 years who were diagnosed with proximal radial fractures treated at our hospital between April 1, 2006 and September 31, 2014. We included 22 patients (9 boys and 13 girls) with a mean age of 8.5 years. Three hand surgeons were blinded to each other's results after examining all the initial radiographs of the injured elbows. To diagnose the fracture, we evaluated computed tomography scans in 9 cases and follow-up radiographs in the other 13 cases. Finally, we classified the fractured olecranon into 3 types: medial crack, posterior flat, and posterior crack. RESULTS: Twelve cases (54.5%) had associated olecranon fractures. According to the fracture type of the olecranon, 3 cases were a medial crack, 5 were a posterior flat, and 3 were a posterior crack. Each type of fracture had characteristic findings on plain radiographs. The mean value for sensitivity was 97.2% (range, 91.7%-100%), and the specificity was 90.0% (90.0%). CONCLUSIONS: Our data indicated that this easy, noninvasive use of plain radiographs for checking whether a longitudinal crack exists on the olecranon benefits the patient by preventing missed diagnoses of pediatric olecranon fractures.

Treatment of a large articular cartilage defect in the distal radius poses a significant challenge to hand surgeons. To reduce the development of secondary degenerative arthritis, restoration of the articular surface is preferable. Pedicle pisiform transfer has been reported as a useful treatment option for Kienböck's disease. We describe a surgical technique involving vascularized pisiform transfer for large cartilage defects after intra-articular distal radius fractures and highlight the vascular supply of the pisiform.

The purpose of this study was to determine whether volar locking plate fixation for distal radius fracture benefits the fragility fracture population as much as it benefits the non-fragility fracture population. This matched case-control study was conducted based on a multi-center clinical prospective cohort. A comparison of treatment outcomes after volar locking plate fixation was made between females 55 years of age and older (fragility fracture population) and males less than 75 years of age (non-fragility fracture population) by evaluating clinical, radiological, and subjective outcomes using Hand20, a validated patient-rated disability instrument. A total of 170 patients were enrolled in this study. The two cohorts were matched in terms of AO fracture type. The fragility fracture population group and the non-fragility fracture population group each consisted of 50 patients. All objective measurements including wrist range of motion and radiological evaluations, but excluding grip strength, were not significantly different between the two groups. However, the Hand20 at 18 months after surgery was worse in the fragility fracture population group than in the non-fragility fracture population group. Carpal tunnel syndrome was the most frequently encountered complication in the fragility fracture population group, with one case (2%) in the non-fragility fracture population group and six cases (12%) in the fragility fracture population group, but the difference was not significant. In conclusion, there was a significant deficit in the improvement in disability despite favorable radiological and functional outcomes in fragility fracture population patients. Therefore, the fragility fracture population, especially middle-aged or older women, needs to be informed about prolonged disability and the higher risk of upper extremity disorders prior to surgery.

We present an extreme rare case of traumatic partial avascular necrosis of the lunate after palmar perilunate dislocation with lunate fracture. A 32-year-old female was injured by motorcycle accident with palmar perilunate fracture dislocation and lunate fracture. Scapholunate and lunotriquetrum dislocations were reduced and fixed temporarily. The torn dorsal ligament was repaired. Considering close observation with both arthroscopy and fluoroscopy, we decided not to conduct open reduction and internal fixation for the lunate. Partial avascular necrosis of the lunate appeared gradually in follow-up.

PURPOSE: We hypothesized that most patients with ulnar impaction syndrome have degenerative changes of the proximal lunotriquetral (LT) membrane and that ulnar-shortening osteotomy is an effective procedure in these patients. METHODS: We retrospectively reviewed 50 wrists of 49 patients with idiopathic ulnar impaction syndrome who underwent an arthroscopic evaluation at the time of ulnar-shortening osteotomy, and subsequently at plate removal. Based on the Geissler classification, patients were divided into group A, normal, and group B, grades I to IV. The degree of degeneration of the proximal LT membrane at first-look arthroscopy was compared with that at second-look arthroscopy. RESULTS: After ulnar-shortening osteotomy, both groups improved significantly in wrist range of motion and grip strength. According to the Mayo wrist score, 29, 18, and 3 patients showed excellent, good, and fair results, respectively. Of the 50 wrists, 25 had degenerative changes (group B) in the proximal LT membrane at the time of first-look arthroscopy. Of the 25 wrists in group B, 11 wrists improved based on the Geissler grade, 9 wrists showed no changes, and 2 wrists became worse. Clinically, patients demonstrated improvement after ulnar-shortening osteotomy regardless of the degree of degenerative LT ligament changes. CONCLUSIONS: Degenerative LT membrane changes that were seen in about half of our patients were mostly of a mild nature, and the clinical outcomes of ulnar-shortening osteotomy were acceptable. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Background: A high incidence of ulnar nerve-related complications has been reported in open reduction and internal fixation for distal humerus fractures (DHFs). To minimise ulnar nerve damage, we used a percutaneous medial screw combined with a posterolateral plate in the elderly. The aim of this study was to evaluate the postoperative complications and functional outcomes of this method. Methods: Data from patients aged over 65 who underwent this surgical procedure for DHFs at a single Level I trauma centre from 2013 to 2021 were extracted. Postoperative complications, reoperations, mean range of motion, Mayo Elbow Performance Index (MEPI) scores and Hand20 scores were retrospectively evaluated. All patients in this study received postoperative rehabilitation by hand therapists at our hospital. Results: We identified 28 patients treated with this method. The mean follow-up period was 8.6 ± 3.7 months. The median intraoperative time was 125 minutes (interquartile range: 105-157 minutes). None of the patients developed ulnar nerve neuropathy, but one patient (3.7%) experienced radial nerve dysfunction. Two patients (7.4%) had nonunion. Implant failure occurred in three patients (11.1%) due to migration of the medial screw. One patient (3.7%) amongst them underwent reoperation. The mean flexion to extension arc was 97 ± 18°, 116 ± 19°, and 116 ± 19° at 1-, 3- and 6-month follow-ups, respectively. According to the MEPI, 20 patients achieved excellent results, seven patients achieved good results and one patient achieved a fair result at the last follow-up. The median Hand20 score was 4.3 (interquartile range: 2.1-14.0) at the 6-month follow-up. Conclusions: The posterolateral plate and medial screw method showed good functional outcomes and few nerve-related complications. This modified method might be a better option for DHFs in elderly patients. Level of Evidence: Level IV (Therapeutic).

BACKGROUND: Reverse homodigital artery island flap (RHDI) has been reported to have some postoperative complications. Cross-finger reverse digital artery island flap (CRDI), which is harvested from an adjacent intact finger, has been used to decrease these complications. This study aimed to provide a review of the CRDI procedure and compare the clinical outcomes of CRDI with those of RHDI. METHODS: RHDI has been performed for fingertip amputations with deficit of 1.5-2.5 cm before 2018, and CRDI has been performed since 2018. We assessed the functional and aesthetic outcomes, including finger length, nail deformity, finger motion, and Hand20 scores at the final follow-up. RESULTS: We identified 22 patients who underwent RHDI and 10 patients who underwent CRDI. The mean follow-up period was 10.3 ± 5.3 months. The median time required for wound healing were 47.0 days (IQR: 34.3-55.8 days) and 34.5 days (IQR: 29.3-44.3 days) in RHDI and CRDI, respectively. The hook nail deformity occurred significantly more frequently in RHDI compared to that in CRDI (40.9% vs. 0.0%, p = 0.03). Flexion contracture of the proximal interphalangeal joint greater than 15º was found to be significantly more in RHDI than in CRDI (36.4% vs. 0.0%, p = 0.04). The median postoperative total active motion of the donor site in CRDI was 278º (IQR: 260-280º). The median postoperative Hand20 scores were similar between the two groups. CONCLUSION: CRDI was associated with superior clinical outcomes in terms of lower rates of postoperative flexion contracture and hook nail deformity, potentially making it a better option compared to RHDI.

BACKGROUND: The purpose of scoring systems is to aid in the decision-making process of whether to salvage or amputate mangled extremities, but their efficacy for upper limbs is uncertain. In this study, we examined the predictive potential of scoring systems for upper limb salvage. METHODS: Two investigators undertook a systematic search of 3 leading databases for English or Japanese literature from 1985, when the first scoring system to evaluate mangled extremities was proposed, until January 2022. To be eligible, studies must have had upper extremity limb salvage or amputation as an outcome, and identified the scoring system used and treatment outcome in individual cases. RESULTS: Ten studies (N = 338) of the Mangled Extremity Scoring System (MESS) were ultimately included in the meta-analysis. The pooled sensitivity and specificity were 0.95 (95 % CI = 0.69-0.99) and 0.81 (0.65-0.91), respectively. The area under the hierarchical summary receiver operating characteristic curve was 0.95 (0.93-0.97). A subgroup analysis showed lower specificity in isolated vascular injuries. Scoring systems other than MESS were ineligible for the quantitative synthesis because none were examined in an adequate number of publications. CONCLUSION: The pooled sensitivity and specificity for MESS were comparable to those reported for the lower extremities. The specificity suggests that limb salvage was achieved in at least 20 % of the patients whose MESS was above the threshold beyond which amputation is indicated. Given the likelihood of upper extremity functional limitations following amputation and the drawbacks of prostheses, we conclude that current scoring systems poorly predict salvageability of a mangled upper extremity and should not be used to justify amputation.

PURPOSE: The Hand10 is a self-administered questionnaire for upper extremity disorders. This questionnaire consists of 10 short, easy-to-understand questions and explanatory illustrations. In the shortening and validation process, the Hand10 demonstrated high acceptability and reliability among elderly individuals, with the advantage of being compact. We hypothesized that attached illustrations may contribute to the ability to maintain the psychometric properties of a questionnaire and raise acceptability for the elderly. METHODS: A series of 106 elderly patients with upper extremity disorders, whose symptoms had been stable, completed the Hand10, the Japanese Society for Surgery of the Hand Version of Disability of the Arm, Shoulder and Hand, and the Revised Hasegawa's Dementia Scale. Participants were randomly allocated to receive either the illustrated Hand10 or the unillustrated Hand10. The potential advantages attributed to attached illustrations were investigated. RESULTS: No significant differences were found in baseline demographic data between subjects who received the illustrated and unillustrated questionnaires. The average percentage of items that the elderly patients left unanswered was 0.5 % for the illustrated Hand10 and 3.8 % for the unillustrated Hand10. Instrument test-retest reliability assessed with the intraclass correlation coefficient was 0.92 and 0.86, respectively. CONCLUSION: The use of explanatory illustrations attached to the Hand10 contributed to raise acceptability for elderly patients and were suggested to improve the reproducibility.
