RESUMO
Background: Pediatric trigger digit (TD) does not appear at birth but is diagnosed after birth by finding a flexion contracture of the thumb or other fingers. The reported incidence of pediatric TDs varies from 0.5 to 5 cases per 1,000 live births without sex-specific predominance. We performed a nationwide large-scale study to determine the prevalence and incidence of pediatric TDs and analyzed operative treatment for pediatric TDs using the National Health Insurance data of South Korea. Methods: Patients with pediatric TDs, aged 0-10 years between 2011 and 2020, were included in this study. Children born between 2011 and 2015 were set as the reference population and followed up until 2020. We calculated the prevalence and incidence rates of pediatric TDs according to age and sex and analyzed the operation rate, age at surgery, time interval from initial diagnosis to surgery, and follow-up period. Patient selection and treatment were based on International Classification of Diseases, 10th Revision (ICD-10). Results: The prevalence rates of pediatric TDs ranged from 0.063% to 0.084%. Girls had a higher prevalence rate (0.066%-0.094%) than boys (0.060%-0.075%). The total incidence rate was 77.6/100,000 person-years, and the incidence rate was higher in girls (84.8) than in boys (70.7). Among 2,181,814 children born between 2011 and 2015, 12,729 were diagnosed with pediatric TDs, of which 1,128 (8.9%) underwent operative management. The means of age at initial diagnosis, age at surgery, and the time interval between diagnosis and operation were 2.76 ± 1.91 years, 3.79 ± 2.19 years, and 1.15 ± 1.71 years, respectively. Conclusions: High prevalence and incidence rates of pediatric TDs were found in 2- to 3-year-old patients. Among pediatric patients, 8.9% underwent operative management that was most frequently conducted between 2 and 3 years of age (within 1 year of initial diagnosis).

BACKGROUND: Trigger thumb is a prevalent hand condition observed in children, and its management remains a topic of considerable debate, ranging from mere observation to surgical intervention. In recent times, there has been a growing interest in exploring nonoperative treatments as alternatives to surgical procedures for managing pediatric trigger thumb. Gaining insight into the prevalence of spontaneous resolution in pediatric trigger thumb is of paramount importance. However, the literature presents a wide variation in estimates regarding the prevalence of this spontaneous resolution, highlighting the need for further investigation and consensus. The aim of this review was to estimate the overall prevalence of spontaneous resolution among pediatric trigger thumb. METHODS: This study meticulously followed the PRISMA guidelines and registered in the PROSPERO. The PubMed, Embase, and Cochrane Library databases were searched for all relevant studies up to May 2024.Inclusion criteria were studies reported only observation spontaneous resolution pediatric trigger thumb, aged up to 14 years, reported at least 10 thumbs and followed up time at least 3 months. Confounded intervention treatment measure studies were excluded. To synthesize the prevalence rates from individual studies, we employed a random-effects meta-analysis. In order to uncover the sources of heterogeneity and to compare prevalence estimates across different groups, we performed sensitivity and subgroup analyses. To meticulously evaluate the quality of the included studies, the Joanna Briggs Institute's quality assessment checklist was employed. Furthermore, to assess the heterogeneity among the studies, both Cochran's Q test and the I² statistic were utilized. RESULTS: A total of eleven studies were included for the final analysis, with 599 pediatric trigger thumbs. Our final meta-analysis showed that more than one-third of these pediatric trigger thumb cases resolved spontaneously, with a resolution rate of 43.5% (95% CI 29.6-58.6). Subgroup analyses showed that in terms of age at the first visit, the prevalence of spontaneous resolution in the less than 24 months group and in the 24 months or older group was 38.7%(95% CI 18.1-64.4)and 45.8%(95% CI 27.4-65.4), respectively. There was no significant difference between the two groups(P = 0.690). When analyzing follow up time, the prevalence of spontaneous resolution in the 24 months or longer group and in the less than 24 months group was 58.9%(95% CI 41.6-74.2)and 26.8%(95% CI 14.7-43.8), respectively.There was significant statistical differences between the two groups(P = 0.009). Based on the initial severity of interphalangeal (IP) joint flexion contracture, the prevalence of spontaneous resolution in the 30 degrees or less group and in the other measurements group was 54.1%(95% CI 31.5-75.1)and 37.1%(95% CI 21.9-55.4), respectively.There was no significant difference between the two groups(P = 0.259). CONCLUSION: Our study demonstrates that a significant proportion of pediatric trigger thumbs resolve spontaneously. This finding highlights the benefits of early observation in managing this condition. By prioritizing non-operative observation, both parents and surgeons are better equipped to make informed decisions regarding the treatment of pediatric trigger thumb, potentially reducing the need for surgical intervention.

OBJETIVE: This article presents a retrospective cohort study analyzing patients from IOT-FMUSP who underwent replantation or revision amputation procedures for traumatic thumb amputation between 2013 and 2020. METHODS: The study included 40 patients in the replanted group and 41 patients in the amputed group. The patients were divided according to the level of amputation and their medical records were analyzed. RESULTS: A total of 81 patients with digital amputation were analyzed, consisting of 79 males and 2 females, with mean ages of 43 and 49 for the amputed and replanted groups, respectively. According to the Biemer classification, 28.4% had proximal amputation, while 71.6% had distal amputation. The most common occupation was bricklayer (19.75%), and 80.24% were manual workers. Of the patients, 65% returned to their previous work, with 77.77% of them having amputation on their non-dominant hand, mostly caused by circular saw accidents (77.77%). The replantation success rate was 78%, with an average ischemia time of 9 hours and door-to-room time of 2 hours. CONCLUSION: the study findings revealed that traumatic thumb amputation predominantly affects working-age males with a low education level and the success rate of replantation was high in this ischemia time and door-to-room conditions. Level of Evidence II, Retrospective study.

RESUMO
OBJECTIVES: Recently, the HAND osteoarthritis (OA) ULTRASOUND (US) Examination (HOUSE) inflammatory and structural damage scores were developed by the OMERACT US working group. However, the thumb base was not or only partly included. This systematic review examines US scoring methods and scanning techniques assessing thumb base OA, alongside existing evidence on validity, reliability, and responsiveness. METHODS: A comprehensive search strategy in three different databases identified 30 eligible studies. RESULTS: In general, studies predominantly focused on US assessment of the carpometacarpal (CMC) 1 joint, with fewer investigating the scaphotrapeziotrapezoid (STT) joint. Most studies utilized a semiquantitative scale for scoring structural and inflammatory features, aligning with the HOUSE scoring system. Validity was supported by a limited number of studies, with one demonstrating a positive association between US structural damage and radiographic damage, and another showing a similar association with function. Associations between US inflammatory features and pain were observed, albeit with some variability. Reliability was from moderate to good for the CMC1 joint but limited for STT joint. Responsiveness varied across studies. The methodological quality of included studies varied, indicating areas for future research improvement. CONCLUSION: While promising, additional research is necessary to validate the HOUSE scoring system and improve its clinical utility for thumb base OA assessment. Future research should concentrate on optimal scanning positions and on the reliability and responsiveness of the HOUSE scoring system.
RESUMO
The most prevalent oral habit and one of the most often habitual behavioral patterns in preschool-aged children is thumb-sucking. This behavior is crucial to the development of malocclusion and must be addressed carefully since it may cause a secondary tongue thrust that worsens the issue. Developing an effective treatment plan requires determining the underlying cause, which may include psychological, physiological, and or anatomical factors. Overall prevention of behavior needs to be planned for successful outcomes. One such device for treating tongue-thrusting and thumb-sucking habits is the palatal crib. The present case shows the possible effectiveness of palatal crib use in conjunction with myofunctional therapy for a child whose diagnosis involves habitually holding the tongue low and sucking the thumb that causes an anterior open bite (AOB). An 11-year-old boy with flared and spaced upper and lower incisors also had an AOB. Myofunctional therapy was combined with palatal cribs to help the tongue reposition itself and discourage the habit of sucking. The AOB was successfully corrected with an appropriate overjet and overbite after a total of three months of treatment.
RESUMO
PURPOSE: This study reviewed the results of the figure-of-eight ligament reconstruction, a technique used in the surgical management of thumb carpometacarpal (CMC) instability. This technique establishes joint stability through forces originating within the CMC joint, providing volar and dorsal support. METHODS: We evaluated the outcomes of 15 patients with nontraumatic, nonarthritic thumb CMC instability treated with the figure-of-eight ligament reconstruction technique. This technique involves routing a graft of the palmaris longus tendon through the base of the first metacarpal and trapezium bone in a figure-of-eight fashion. Preoperative visual analog scale (0-100) for pain and Michigan Hand Outcomes Questionnaire total scores were compared with 3- and 12-month postoperative scores. Secondary outcomes included strength, range of motion, patient satisfaction, return to work, and complications. RESULTS: A significant improvement between intake and 12 months after surgery was observed for both Michigan Hand Outcomes Questionnaire total scores (53, SD 3 vs 70, SD 4) and visual analog scale pain scores (63, SD 4 vs 36, SD 7). Additionally, after surgery, restored thumb CMC joint stability was reported for all patients. Strength and range of motion improved between intake and 12 months after surgery. The median return to work was 6 weeks. Nine (60%) patients rated their satisfaction as "excellent" or "good," and 11 (73%) patients said that they would undergo the surgery again. CONCLUSIONS: The figure-of-eight ligament reconstruction significantly improves pain and function in patients with thumb CMC instability while restoring joint stability and preserving range of motion, making it a suitable technique. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
RESUMO
Engaging patients and family members in formal feedback for health care processes can be impactful, especially when cultivating new care and research protocols. However, most surgical groups lack established systems for enlisting these critical stakeholders. This is a descriptive report of how we built our Patient and Family Advisory Council (PFAC) through a multistep process with patients, providers, research staff, and administrators. We also detail how it has advanced research, care, and mutually beneficial collaboration at our hand center. For example, our PFAC has provided vital input on multiple grant submissions, assisted with the development of a web-based digital application for thumb arthritis therapy, and improved our patient care approaches. To successfully create and sustain a PFAC, there must be commitment from multiple stakeholders across clinical, research, administration, and leadership spectra. Through this alliance, all stakeholders can develop better care and investigative strategies.
RESUMO
Purpose: Pediatric trigger thumb is a common condition resulting in referral from primary care to specialty care. Access to pediatric hand specialty care is a complex issue influenced by a multitude of social factors, including socioeconomic status. The aim of this study is to investigate the relationship between area deprivation and the time from primary care referral to presentation to specialty care for pediatric trigger thumb. Methods: Participants were pediatric patients with trigger thumb. Patient-level area deprivation was reflected by the area deprivation index (ADI). We analyzed the relationship of the ADI to patient demographics (age and sex), trigger thumb treatment (surgical vs nonsurgical), and time to initial hand surgical visit after referral and surgical management when indicated. Results: Among 163 patients with trigger thumb, 52% were men. Mean age at referral for trigger thumb was 2.9 ± 1.7 years. Mean ADI for patients diagnosed with trigger thumb was 57.8 ± 23.4 for the 2018 data set and 57.3 ± 23.6 for the 2021 data set, on a scale of 1 (low) to 100 (high). The median time from referral from primary care to presentation to orthopedic care for trigger thumb was 34 days. Upon presentation to treating hand surgeon, 118 patients (72.4%) underwent surgical release. We found no difference in ADI between men and women nor between patients treated operatively or with nonsurgical management. We found a weak positive correlation between ADI and time from initial referral to presentation to the treating hand surgeon. There was no correlation between ADI and time from initial hand surgical evaluation and surgical management in patients indicated for surgery. Conclusions: Pediatric trigger thumb patients from areas with higher ADI have a slightly longer delay between initial referral and their initial visit with an orthopedic hand specialist. Although we found a delay in initial evaluation by the treating hand surgeon in patients with higher ADI, ADI status was not different between patients managed with surgical and nonsurgical treatment nor between men and women. Clinical relevance: Neighborhood ADI weakly correlated with increased time from referral to accessing specialty orthopedic care for trigger thumb. This may suggest a need for more equitable access to specialty care for patients with pediatric trigger thumb from high ADI areas.
RESUMO
We invited 14 women who had undergone implant arthroplasty in one thumb and resection-suspension-interposition arthroplasty (RSIA) in the other to a follow-up visit at a median time of 2.2 and 6.2 years after implant and RSIA, respectively. In total, 12 patients were satisfied or very satisfied with the outcome after implant arthroplasty, while eight patients reported this level of satisfaction for RSIA. Of the patients, 10 would choose an implant again, one would choose RSIA and three patients were undecided. The brief Michigan Hand Outcomes Questionnaire score and key pinch and grip strengths were significantly higher at follow-up for the thumb with the implant arthroplasty. Two revision operations were done 1.5 years after RSIA. Patients were satisfied with both procedures, but if they had to choose again, they would prefer implant arthroplasty.Level of evidence: III.
RESUMO
AIMS: The primary aim of this study was to assess functional and patient reported outcomes among those with first carpometacarpal joint osteoarthritis treated with the Pyrocardan implant (Stryker-Wright Medical) in Ireland. The secondary aim of this study was to assess implant survival and revision rates. METHODS: We conducted a single surgeon retrospective study assessing 40 Pyrocardan arthroplasties among 37 patients, with a minimum of 6 months follow-up. Patient reported outcomes were assessed via quick disability of the arm, shoulder and hand (quick DASH) questionnaire, the visual analog score (VAS) for pain, and patient rated wrist evaluation (PRWE) questionnaire. Functional scores were assessed via lateral key pinch strength and Kapandji scores. Implant survival, complication and revision rates were also recorded. RESULTS: Forty Pyrocardan implants among 37 patients were included. Mean follow-up was 2.5 years with a 97.5% implant survival rate. One patient underwent revision to trapeziectomy and Weilby sling. Eighty-eight percent of survey responders admitted that they would undergo the operation again, and 75% declared a 75-100% improvement in symptoms. Post-operative pain scores include a mean VAS of 2.07, quickDASH of 22.82, and PRWE of 26.92. Of those tested, there was an average increase in post-operative lateral key pinch, and 89% obtained a post-operative Kapandji score equal to or better than pre-operative scores. CONCLUSIONS: This is the first study assessing the Pyrocardan interpositional arthroplasty in Ireland. The implant appears to produce good functional and patient reported outcomes. There is high satisfaction and low revision rate, producing a reliable and successful surgical technique for treating CMC joint osteoarthritis.
RESUMO
Holt-Oram syndrome is an autosomal dominant condition marked by heart and upper limb defects. Holt and Oram were the first to narrate this in 1960. Holt-Oram syndrome is the prototype of heart-hand syndromes and has recently been mapped to the long arm of chromosome 12 (12q2). This syndrome was described in 1960 by Dr Mary Holt and Dr Samuel Oram. It is an autosomal dominant condition resulting from a mutation in TBX5 located on chromosome 12q24.1, which regulates cardiac and limb morphogenesis. It must be differentiated from heart-hand syndrome type II (Tobatznik's syndrome) and heart-hand syndrome type III (MIM No. 140450), which are phenotypically similar. The latter do not map to 12q2, and atrial septal defects do not occur in these conditions. This syndrome is distinguished by heart problems as well as thumb aplasia or hypoplasia. It is sometimes referred to as atriodigital syndrome, upper limb-cardiovascular syndrome, heart-hand syndrome, cardiomelic syndrome, or cardiac limb syndrome. Other upper-limb anomalies include aplasia or hypoplasia of the radius, arm length variation, atypical forearm pronation and supination, uncommon thumb resistance, sloping shoulders, and restricted shoulder movement. All those who are affected have an aberrant carpal bone, which might be the only sign of the illness. Seventy-five percent of those with Holt-Oram syndrome have a congenital cardiac defect, which most frequently affects the septum. In this case, we report a girl who is 4 years and 6 months old and is a known case of Holt-Oram syndrome with an atrial septal defect. She underwent device closure and had come to the pediatric op with fever and cough.
RESUMO
INTRODUCTION AND IMPORTANCE: Polydactyly of the hand is a common anomaly among pediatrics, which can present in conjugation with other syndromes or on its own. Various types can be seen, ranging from the involvement of skin only to a completely formed digit. We report the first case of pacifier type thumb duplication presenting with VACTERL association. Herein, we also summarize the existing literature of the distinctive features and management of pacifier polydactyly. CASE PRESENTATION: A premature male infant with intrauterine growth restriction due to maternal type II diabetes was referred for a soft tissue attachment to the left hand. The infant showed VACTERL association signs, including a single kidney, small atrial septal defect, and ventricular septal defect. Examination revealed preaxial polydactyly with a cystic swelling connected to the palm. CLINICAL DISCUSSION: Preaxial polydactyly is the second most common congenital hand anomaly, and its pathology is thought to involve the disruption of apoptosis during embryonic development. Pacifier-type polydactyly is a unique variation characterized by severe edema of the soft tissue digit, believed to be caused by physical damage in utero. The case presented did not require surgical intervention as the duplicated thumb underwent spontaneous autoamputation as opposed to other cases in the literature. CONCLUSION: This is the first reported case of pacifier-type thumb duplication in a patient with VACTERL association. The presentation of this condition adds to the existing body of literature on VACTERL association. Surgical removal is the treatment of choice for pacifier polydactyly, but spontaneous resolution can occur.
RESUMO
Background: This study aimed to investigate the effect of thumb metacarpal osteotomy on dorsal subluxation of the carpometacarpal (CMC) joint and compare the effects of early and advanced osteoarthritis (OA). Methods: We retrospectively reviewed 42 thumbs of 37 patients who underwent metacarpal osteotomy with a postoperative extension angle of 90° or more between January 2018 and October 2021 and were followed up for more than 2 years. The thumbs were classified into two groups: early OA (Eaton stage I or II) and advanced OA (Eaton stage III). We measured the reduction ratio, which was defined as the ratio of improvement in dorsal subluxation, at 3 months and 1 year postoperatively, and at the latest follow-up. We statistically compared the reduction ratio between the two groups and investigated the factors affecting the reduction ratio using correlation analysis. Results: The reduction ratio was significantly higher in the early OA group than in the advanced OA group at 3 months after surgery, whereas no significant difference was found between the two groups at 1 year after surgery and at the latest follow-up. A significant positive correlation was detected between the reduction ratio and the postoperative extension angle. Conclusions: First metacarpal osteotomy reduces dorsal subluxation in both early- and advanced-stage CMC OA. This procedure yields immediate marked reduction in early-stage OA, while improvement of the subluxation progressed gradually in advanced-stage OA. Level of Evidence: Level IV (Therapeutic).
RESUMO
Acute traumatic dislocation without fractures of the thumb carpometacarpal (CMC) joint is extremely rare in children. Treatment options, such as closed reduction with casting or pinning and open reduction with primary ligament repair, remain controversial. Here, we report the first case of an 11-year-old boy with recurrent left thumb CMC joint dislocation due to idiopathic generalized hyperjoint laxity, even after primary open reduction with capsular ligament repair of the thumb CMC joint, eventually treated with Eaton-Littler's ligament reconstruction. Intraoperatively, a drill hole was made in the base of the first metacarpal bone while carefully preventing growth plate injury. Primary ligament reconstruction of the thumb CMC joint may be considered in pediatric cases with systemic hyperjoint laxity or recurrent thumb CMC joint dislocation. In such cases, Eaton-Littler's ligament reconstruction is recommended for thumb CMC joint stability because two prime stabilizers of the dorsoradial ligament and the volar anterior oblique ligament (AOL) are appropriately reconstructed by a half-slip of the flexor carpi radialis tendon.
RESUMO
Background and objective De Quervain's tenosynovitis is a highly prevalent wrist pathology primarily caused by chronic thumb overuse. Its management typically begins with conservative methods, progressing to corticosteroid injections or surgery if necessary. This study compares the efficacy of thumb spica casting plus corticosteroid injection versus casting alone for treating De Quervain's tenosynovitis. Materials and methods This quasi-experimental study was conducted at the Department of Orthopaedics, Khyber Teaching Hospital, Peshawar, and enrolled adults aged 18-50 who presented with De Quervain's tenosynovitis. Patients were assigned to receive either corticosteroid injection plus thumb spica cast (Group A) or thumb spica cast alone (Group B). The primary outcome assessed the treatment success rate, while the secondary outcome evaluated the treatment effectiveness using visual analog scale (VAS) scores and Quick Disabilities of Arm, Shoulder, and Hand (QuickDASH). Results Of the initial 65 patients enrolled, 61 completed the study. Group A demonstrated a significantly higher treatment success rate (83.9%, n=26) compared to Group B (40%, n=12) (p<0.001). Pain reduction, as measured by VAS, was markedly greater in Group A (8.4 ± 1.0 to 0.4 ± 0.5) than in Group B (9.0 ± 0.8 to 5.9 ± 1.3) (p<0.001). Similarly, functional improvement assessed by QuickDASH favored Group A (89.6 ± 8.2 to 8.9 ± 6.8) over Group B (84.3 ± 10.1 to 49.1 ± 12.3) (p<0.001). No serious adverse effects related to treatments were noted in either of the groups. Conclusions This study supports the superiority of thumb spica casting along with local corticosteroid injection over casting alone for treating De Quervain's tenosynovitis. The combined approach led to significantly better pain relief and functional outcomes, highlighting its effectiveness as a treatment option despite the positive outcomes observed with casting alone.
RESUMO
Background: The treatment of severely displaced Rockwood and Wilkins' type C (RWC) thumb metacarpal basal fractures remains controversial in children. This retrospective study aimed to compare the efficacy of two treatment methods, open vs. closed reduction with pinning of such injuries. Methods: This study included 30 patients with open physes, 14 boys and 16 girls, who all received either closed or open reduction treatment. The primary outcomes of interest included healing time, complications, and functional results, which were evaluated using the improved Mayo score standard. The minimum follow-up period was 24 months, with a mean of 30.3 months (range 24.0-45.0 months). Statistical significant was defined as P < 0.05. Results: All fractures were healed within 7 weeks after surgery, regardless of which surgical approach was used. However, the recovery time was markedly faster in the closed group, with a mean of 4.2 weeks, than in the open group, with a mean of 4.7 weeks (P < 0.05). The operation time for closed group, taking 20â min in average, was also shorter than that for open group (P < 0.05). The total incidence of mild complications was lower for patients in the closed group than for patients in the open group (6.3% vs. 21.4%, P < 0.05). No major complications were observed in either group. In the closed group, a total of 15 patients exhibited excellent outcomes, while only one patient demonstrated good outcomes. On the other hand, in the open group, 12 patients experienced excellent outcomes, whereas two patients had good outcomes. There were no instances of osteomyelitis, refractures or nonunion, avascular necrosis (AVN), or premature physeal closure in either group. Conclusion: The data from the open group and closed group procedures for severely shifted RWC fractures in children indicate comparable prognoses and complication rates between the two groups. Obviously closed reduction, in particular, offers several advantages over open procedure, including shorter surgical duration, fewer K-wires required, and no need for open incisions. Consequently, closed reduction is the preferred method for treating such RWC fractures.
RESUMO
PURPOSE: Total joint arthroplasty (TJA) has often been used to treat thumb carpometacarpal (CMC) osteoarthritis (OA). However, guidelines for the CMC prosthesis shape remain unclear. This study aimed to identify the effective shape of a ball-and-socket prosthesis in restoring the range of thumb motion after TJA. METHODS: The participants were 10 healthy young adult men (22-32 years; 26.8 ± 3.57 [mean ± SD]). CT scans were performed in eight static limb positions during abduction and flexion. We defined three design variables (offset R, height H, and neck rotation angle Φ) as the variables that determine the basic shape of the ball-and-socket prosthesis. The ideal values of these design variables were examined based on the results of a 3D motion analysis, which evaluated the change in the posture of the first metacarpal (r, h, and φ corresponding to R, H, and Φ, respectively) relative to the center of rotation (COR) during abduction and flexion. We also simulated the effect of these design variables on the range of thumb motion after TJA using 3D CAD. RESULTS: We found that the values of r and h averaged over all limb positions were 6.92 ± 1.60 mm and 51.02 ± 1.67 mm, respectively, showing that these values remained constant regardless of limb position. In contrast, φ changed significantly. The simulation results indicated that Φ affected the range of thumb motion after TJA, and Φ = 0° relatively reproduced all limb positions compared to other values. CONCLUSION: Our results suggested that the desirable values of R and H were the average of r and h over several limb positions and that Φ = 0° was effective in restoring the range of thumb motion after TJA. Our results will provide surgeons with new guidelines for selecting a prosthesis.

CLINICAL FEATURES: The click phenomenon occurs when an acquired mechanical restriction of the elevation in adduction of the eye or of the extension of the finger/thumb, is forcefully overcome. The common cause is a nodule either of the superior oblique tendon posterior to the trochlea in the case of a Jaensch-Brown syndrome or of the digital flexor tendon anterior to the A1 annular pulley in the case of a trigger finger. Both locations share similar anatomical conditions for the development of the nodule and the pathomechanism of the click. RESULTS: From these identical findings in the eye and the hand in small children it can be assumed that the results from the studies of the hand in newborns and infants with a trigger thumb/finger are also applicable to the situation of the eye. 1. This motility disorder is not congenital. This is most likely due to an incomplete development at the time of birth of the sliding factors needed for a free passage of the tendon through the trochlea and the A1 annular pulley. 2. A distinction must be made between stages 0-3: stage 0â¯= no more restriction of the motility and no click phenomenon; stage 1â¯= forced active extension/elevation possible; stage 2â¯= only passive extension/elevation, each with a click phenomenon; stage 3â¯= no extension/elevation possible and no click phenomenon. 3. In most cases in early childhood there is a spontaneous complete recovery (75% after 6-7 years). In the eye this spontaneous course can only limitedly be shortened with motility exercises in combination with segmental occlusion. CONCLUSION: The click phenomenon is a symptom of stages 1 and 2 of an acquired mechanical restriction of the elevation in adduction of the eye or the extension of the finger/thumb. It should not be called a syndrome.

OBJECTIVE: This study aimed to investigate to what extent people with carpometacarpal thumb osteoarthritis that are socioeconomically disadvantaged and have psychological disorders report higher pain levels and worse patient-rated upper-extremity functionality after surgical treatment. MATERIAL AND METHOD: A single center, retrospective observational cohort study analysing 100 patients diagnosed with thumb carpometacarpal osteoarthritis between 2013 and 2019. Patients were divided into two groups (50/50), depending on whether they received surgical or conservative treatment. The socio-economic status (ESeC classification) and presence of psychological comorbidities were investigated. Functional outcomes were assessed using the Visual Analogue Scale (VAS), Q-DASH questionnaire and Kapandji score. Current mental disorders were evaluated using STAI, PHQ-9 and PCS screening scales. RESULTS: Measures of functional hand scores (Q-DASH) were higher and had considerably less pain in surgically treated participants, although thumb mobility (Kapandji) was more restricted. They were also associated with higher scores on psychological assessment scales. Sixty-four per cent of the patients came from lower socio-economic classes and suffered from poorer scores on the mental health screening questionnaires. Of the patients manage surgically, 54% were diagnosed of dysthymic disorder and showed significantly worse patient-rated upper-extremity function (Q-DASH questionnaire, median [IR]:31,8 [20,5-54,6] than patients without psychological disorders (median [IR]: 13,6 [2,3-36,5]). No differences were found for patients with and without disthymic disorder managed nonoperatively. CONCLUSIONS: Patients with higher rates of depression, anxiety and pain catastrophizing behaviour showed significantly worse outcomes after surgery for osteoarthritis of the first carpometacarpal joint. Lower socio-economic class significantly influences levels of depression and anxiety but did not affect functional outcome. Surgical treatment of carpometacarpal thumb osteoarthritis achieved better self-perceived hand function (QDASH, VAS, Kapandji) than conservative treatment.
RESUMO
PURPOSE: The aim of this study is to assess the time to return to work (TRW) in patients undergoing trapezial resection using the Mini TightRope® system at our centre and to investigate factors that might delay return to work following this surgery. MATERIAL AND METHODS: A retrospective study was conducted on patients who underwent Trapezial resection and suspensionplasty using the Mini TightRope® system between 2015 and 2016, with a minimum one-year follow-up. Telephone interviews were conducted along with a review of medical records and radiology reports, as well as temporary work disability documents, collecting epidemiological and occupational data. Groups were compared based on age, gender, dominant hand, biomechanical occupational requirements of the patients, and whether they had experienced prior temporary work disability. RESULTS: A total of 36 patients (29 women and 7 men) with an average age of 55.7 years were included. The median time to return to work was 126 days. Self-employed workers re-entered the workforce 72 days earlier on average; workers who had experienced prior temporary work disability had a greater total temporary work disability duration and took 91 days longer to return to work compared to those who had not. CONCLUSIONS: Patients employed by others and those who had experienced prior temporary work disability before the surgery had longer temporary work disability periods. In our study, no differences were observed based on gender, dominant hand, or biomechanical work demands of the intervened patients.
