Surgical Techniques in Non-Traumatic Midcarpal Instability: Evaluating the Dorsal Capsulodesis and Three-Ligament Tenodesis Technique.

BACKGROUND: Surgical management of midcarpal instability (MCI), also referred to as carpal instability nondissociative, remains controversial due to limited evidence on different techniques. This study aimed to assess and compare differences in patient-reported pain, hand and wrist function, patient satisfaction, range of motion, and return to work in patients with non-traumatic MCI who underwent surgical treatment either through dorsal wrist capsulodesis or three-ligament tenodesis (3LT). METHODS: Patients with MCI and persisting complaints after conservative therapy treated with 3LT or dorsal capsulodesis were included. Patients with posttraumatic instability were excluded. Primary endpoints included the Patient Rated Wrist Evaluation (PRWE) and Satisfaction with Treatment Result Questionnaire at 12 months postoperative. All data were retrospectively analyzed. RESULTS: A total of 91 patients treated with dorsal capsulodesis and 21 treated with 3LT between December 2011 and December 2019 were included. At twelve months postoperative, both treatment groups reported significant improvements in pain and function scores. However, at three months postoperative, the dorsal capsulodesis group exhibited significantly better outcomes, followed by a greater return to work (72%) compared to the 3LT group (50%). However, the capsulodesis group demonstrated a decreased range of motion at three months which was restored at 12 months postoperative. No significant difference in satisfaction with treatment was observed. CONCLUSIONS: Both 3LT and dorsal capsulodesis demonstrate promising results for addressing non-traumatic MCI. However, considering the quicker recovery and faster return to work associated with dorsal capsulodesis, we recommend favoring capsulodesis over 3LT when both surgical options are deemed suitable for the patient.

Reconstruction of an early stage SLAC wrist with the 3-LT procedure: A controversial reappraisal.

OBJECTIVE: We hypothesized that the three-ligament tenodesis (3-LT) procedure is still sufficient - even in scapholunate advanced collapse (SLAC) cases - to reduce pain and improve wrist function. We compared patient-reported outcomes of scapholunate interosseus ligament (SLIL) injury patients with SLAC to SLIL injury patients treated with 3-LT, and then to patients who received proximal row carpectomy (PRC), as a control group. METHOD: We included all patients with a traumatic SLIL injury and associated SLAC components treated with 3-LT and completed Patient Reported Wrist Evaluation (PRWE) questionnaires preoperative and at 12 months follow-up. First, we compared matched patients with SLIL injury and SLIL injury with SLAC, stage 1-3, who received 3-LT. Second, we compared patients who received 3-LT, with patients who underwent PRC, while having SLAC stage 2-3. RESULTS: We compared 51 patients with SLAC to 95 with SLIL injury who had a 3-LT procedure, and 10 3-LT patients were compared to 18 patients undergoing PRC, given SLAC 2-3. In both analyses, the PRWE scores had significantly improved in all groups, however no significant differences in PRWE were found between 3-LT in SLIL injury and SLIL injury with SLAC, 6.9 points (95% CI [-14.92; 1.22], p = 0.096) and between 3-LT and PRC, given SLAC stage 2-3, 15.1 points (not enough power). CONCLUSION: There is no difference in PRWE between matched SLIL injury patients with or without degenerative changes treated with a 3-LT. Therefore, the 3-LT procedure seems to be a viable treatment option for patients with early-stage SLAC wrist. LEVEL OF EVIDENCE: Therapeutic III.

Outcomes of an exercise program in patients with dorsal or volar midcarpal laxity: a cohort study of 213 patients.

PURPOSE: Describing the outcomes of an exercise program on wrist and hand function for patients with midcarpal instability (MCI). MATERIALS AND METHODS: This study has a prospective cohort design. Two hundred and thirteen patients with MCI were included. The intervention was a 3-month exercise program consisting of hand therapy and home exercises. The primary outcome was perceived wrist and hand function evaluated with the Patient-Rated Wrist/Hand Evaluation (PRWHE) three months after treatment onset. Secondary outcomes were conversion to surgery, pain, and satisfaction with treatment results. RESULTS: PRWHE total scores improved from 51 ± 19 (mean ± SD) to 33 ± 24 at 3 months (95% CI: 36-30, p < 0.001). All visual analog scales for pain demonstrated clinically relevant improvements at 6 weeks and 3 months (p < 0.001). At 3 months, 81% of the participants would undergo the treatment again. After a median follow-up of 2.8 years, 46 patients (22%) converted to surgery. CONCLUSIONS: We found clinically relevant improvements in hand and wrist function and pain. Most participants would undergo treatment again and 78% of the participants did not convert to surgery. Hence, non-invasive treatment should be the primary treatment choice for patients with MCI.

Midcarpal instability (MCI) is a disabling condition and treatment options are limited.Patients with MCI can benefit from an exercise program aiming to improve the strength and coordination of the wrist muscles.Participants improved in hand/wrist function and 78% did not convert to surgery.Non-invasive treatment should be the primary treatment choice for these patients.

Prevalence of Complications and Association With Patient-Reported Outcomes After Trapeziectomy With a Weilby Sling: A Cohort Study.

PURPOSE: The primary aim of this study was to report complications during the first year after trapeziectomy with Weilby sling using a standardized tool designed by the International Consortium for Health Outcome Measures. The secondary aim was to determine the association of complications and patient-reported outcomes 12 months after surgery. METHODS: We included patients who underwent trapeziectomy with Weilby sling between November 2013 and December 2018. All complications during the first year were scored using the International Consortium for Health Outcomes Measurement Complications in Hand and Wrist conditions (ICHAW) tool. Pain and hand function were measured before surgery and 12 months after surgery using the Michigan Hand Outcomes Questionnaire (MHQ). Minimally Important Change thresholds of 18.6 for MHQ pain and 9.4 for MHQ function were used to determine clinical importance. RESULTS: Of 531 patients after trapeziectomy with Weilby sling, 65% had an uneventful recovery, 16% experienced ICHAW Grade 1 deviations only, and 19% experienced Grade 2 or 3 deviations, including requiring antibiotics, corticosteroid injections, or additional surgery. On average, patients improved in pain and hand function, even in the presence of ICHAW events. Although all ICHAW grades were associated with poorer patient-reported outcomes 12 months after surgery, Grade 2 and 3 exceeded the Minimally Important Change threshold for pain and/or function. CONCLUSIONS: In 531 patients, 65% had an uneventful recovery, 16% experienced ICHAW Grade 1 deviations only, and 19% experienced grade 2 or 3 deviations. We recommend describing Grade 1 as "adverse protocol deviations" and grade 2 and 3 as complications, because of clinically relevant poorer patient-reported outcomes 12 months after surgery. The ICHAW is a promising tool to evaluate systematically and compare complications in hand surgery, although we recommend further evaluation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Biomechanical Outcomes of Surgically Repaired TFCC Palmer Type 1B Tears: A Systematic Review of Cadaver Studies.

BACKGROUND: Palmer type 1B triangular fibrocartilage complex (TFCC) tears are a common cause of distal radioulnar joint (DRUJ) instability. Unfortunately, the best surgical technique for TFCC reinsertion is still unknown, and up to a quarter of patients report instability after repair. The purpose of this systematic review of cadaver studies was to compare the biomechanical outcomes of different surgical techniques used for Palmer 1B TFCC tears. METHODS: A systemic review of all cadaver studies published before January 2022 was performed using the PubMed and EMBASE databases. Only cadaver studies on reinsertion techniques for Palmer type 1B lesions were included. Biochemical outcome parameters evaluated were stability of the DRUJ and strength of the repair. RESULTS: A total of 248 articles were identified. Five articles fulfilled the inclusion criteria. Four different surgical techniques were identified. In 3 studies, transosseous tunnel repair was tested and resulted in the most stable DRUJ and strongest TFCC repair compared with the suture anchor repair, the peripheral capsular repair, and the outside-in repair. CONCLUSIONS: These results suggest that the transosseous tunnel repair might be a good technique for restoring DRUJ stability. However, more cadaver studies are needed to identify the most optimal technique.

Involvement in a Personal Injury Claim Is Associated With More Pain and Delayed Return to Work After Elective Nonsurgical or Surgical Treatment for Hand or Wrist Disorders: A Propensity Score-matched Comparative Study.

BACKGROUND: A small proportion of patients treated for a hand or wrist condition are also involved in a personal injury claim that may or may not be related to the reason for seeking treatment. There are already indications that patients involved in a personal injury claim have more severe symptoms preoperatively and worse surgical outcomes. However, for nonsurgical treatment, it is unknown whether involvement in a personal injury claim affects treatment outcomes. Similarly, it is unknown whether treatment invasiveness affects the association between involvement in a personal injury claim and the outcomes of nonsurgical treatment. Finally, most studies did not take preoperative differences into account. QUESTIONS/PURPOSES: (1) Do patients with a claim have more pain during loading, less function, and longer time to return to work after nonsurgical treatment than matched patients without a personal injury claim? (2) Do patients with a personal injury claim have more pain, less function, and longer time to return to work after minor surgery than matched patients without a personal injury claim? (3) Do patients with a personal injury claim have more pain, less function, and longer time to return to work after major surgery than matched patients without a personal injury claim? METHODS: We used data from a longitudinally maintained database of patients treated for hand or wrist disorders in the Netherlands between December 2012 and May 2020. During the study period, 35,749 patients for whom involvement in a personal injury claim was known were treated nonsurgically or surgically for hand or wrist disorders. All patients were invited to complete the VAS (scores range from 0 to 100) for pain and hand function before treatment and at follow-up. We excluded patients who did not complete the VAS on pain and hand function before treatment and those who received a rare treatment, which we defined as fewer than 20 occurrences in our dataset, resulting in 29,101 patients who were eligible for evaluation in this study. Employed patients (66% [19,134 of 29,101]) were also asked to complete a questionnaire regarding return to work. We distinguished among nonsurgical treatment (follow-up at 3 months), minor surgery (such as trigger finger release, with follow-up of 3 months), and major surgery (such as trapeziectomy, with follow-up at 12 months). The mean age was 53 ± 15 years, 64% (18,695 of 29,101) were women, and 2% (651 of 29,101) of all patients were involved in a personal injury claim. For each outcome and treatment type, patients with a personal injury claim were matched to similar patients without a personal injury claim using 1:2 propensity score matching to account for differences in patient characteristics and baseline pain and hand function. For nonsurgical treatment VAS analysis, there were 115 personal injury claim patients and 230 matched control patients, and for return to work analysis, there were 83 claim and 166 control patients. For minor surgery VAS analysis, there were 172 personal injury claim patients and 344 matched control patients, and for return to work analysis, there were 108 claim and 216 control patients. For major surgery VAS analysis, there were 129 personal injury claim patients and 258 matched control patients, and for return to work analysis, there were 117 claim and 234 control patients. RESULTS: For patients treated nonsurgically, those with a claim had more pain during load at 3 months than matched patients without a personal injury claim (49 ± 30 versus 39 ± 30, adjusted mean difference 9 [95% confidence interval (CI) 2 to 15]; p = 0.008), but there was no difference in hand function (61 ± 27 versus 66 ± 28, adjusted mean difference -5 [95% CI -11 to 1]; p = 0.11). Each week, patients with a personal injury claim had a 39% lower probability of returning to work than patients without a claim (HR 0.61 [95% CI 0.45 to 0.84]; p = 0.002). For patients with an injury claim at 3 months after minor surgery, there was more pain (44 ± 30 versus 34 ± 29, adjusted mean difference 10 [95% CI 5 to 15]; p < 0.001), lower function (60 ± 28 versus 69 ± 28, adjusted mean difference -9 [95% CI -14 to -4]; p = 0.001), and 32% lower probability of returning to work each week (HR 0.68 [95% CI 0.52 to 0.89]; p = 0.005). For patients with an injury claim at 1 year after major surgery, there was more pain (36 ± 29 versus 27 ± 27, adjusted mean difference 9 [95% CI 4 to 15]; p = 0.002), worse hand function (66 ± 28 versus 76 ± 26, adjusted mean difference -9 [95% CI -15 to -4]; p = 0.001), and a 45% lower probability of returning to work each week (HR 0.55 [95% CI 0.42 to 0.73]; p < 0.001). CONCLUSION: Personal injury claim involvement was associated with more posttreatment pain and a longer time to return to work for patients treated for hand or wrist disorders, regardless of treatment invasiveness. Patients with a personal injury claim who underwent surgery also rated their postoperative hand function as worse than similar patients who did not have a claim. Depending on treatment invasiveness, only 42% to 55% of the personal injury claim patients experienced a clinically relevant improvement in pain. We recommend that clinicians extensively discuss the expected treatment outcomes and the low probability of a clinically relevant improvement in pain with their personal injury claim patients and that they broach the possibility of postponing treatment. LEVEL OF EVIDENCE: Level III, therapeutic study.

Comparing Patient-Reported Outcomes on Three-Ligament Tenodesis between Partial and Complete Scapholunate Ligament Injuries: A Cohort Study.

PURPOSE: Multiple studies report outcomes after 3-ligament tenodesis (3-LT) in treating traumatic scapholunate interosseous ligament injury (SLIL). However, investigators do not differentiate between patients with partial or complete SLIL injury. The relation between the extent of SLIL disruption and surgical outcomes and if this should be considered when treating a patient with SLIL injury remains unknown. We aimed to evaluate differences in patient-rated wrist evaluation (PRWE) scores, satisfaction and return to work between patients with partial or complete chronic traumatic SLIL injury treated with 3 ligament tenodesis at 12 months after surgery. METHODS: All patients with chronic SLIL injury (partial and complete) who were treated with 3-LT at our clinic and received the same postoperative management between December 2011 and December 2019 were studied. Only patients who had completed the PRWE and return to work questionnaires preoperatively and 12 months after surgery were included. Patients were allocated to the partial (classified as Geissler 2 or 3) or complete SLIL injury group (classified as Geissler 4) by retrospectively assessing wrist arthroscopy reports. RESULTS: Thirty-nine patients with partial and 90 with complete SLIL injuries were included. At 1-year follow-up, PRWE scores had significantly improved in both groups. When adjusting for clinical baseline characteristics, there was no statistically significant difference between patients with partial or complete SLIL injury. Patients with complete SLIL injury had a 70% higher return to work within the first 12 months after 3-LT; however, satisfaction with the treatment result was similar for both study groups 1 year after surgery. CONCLUSIONS: Patients with complete and partial traumatic SLIL injury report better PRWE total scores at 12 months after 3-LT, but there was no statistically significant difference between the groups in PRWE scores or satisfaction with the treatment result. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Routinely-Collected Outcomes of Proximal Row Carpectomy.

PURPOSE: To describe patient-reported pain and function 12 months after proximal row carpectomy (PRC). Secondary outcomes included return to work, grip strength, range of wrist motion, satisfaction with treatment results, and complications. METHODS: This cohort study was part of the British Society for Surgery of the Hand Studyathon 2021, using ongoing routinely-collected data of 304 eligible patients who underwent PRC (73% scapholunate advanced collapse, 11% scaphoid nonunion advanced collapse wrist; 11% Kienböck, 5% other indications) from Xpert Clinics, the Netherlands between 2012-2020. The primary outcome was the Patient Rated Wrist/Hand Evaluation total score (range, 0-100, lower scores indicate better performance). RESULTS: Of the 304 patients, the primary outcome was available in 217 patients. The total Patient Rated Wrist/Hand Evaluation score improved from 60 (95% confidence interval [CI], 57-63) to 38 (95% CI, 35-41) at 3 months, and 26 (95% CI, 23-29) at 12 months. The pain and function subscales improved by 18 (95% CI, 17-20) and 16 (95% CI, 14-18) points, respectively. At 12 months, 82% had returned to work at a median time of 12 (95% CI, 9-14) weeks following PRC. Grip strength did not improve. Wrist flexion and extension demonstrated a clinically irrelevant decrease. Satisfaction with treatment result was excellent in 27% of patients, good in 42%, fair in 20%, moderate in 6%, and poor in 5%. Complications occurred in 11% of patients, and conversion to wrist arthroplasty occurred in 2 patients. CONCLUSION: A clinically relevant improvement in patient-reported pain and function was observed at 3 months after PRC, with continued improvement to 12 months. These data can be used for shared-decision making and expectation management. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Collaborative hand surgery clinical research without sharing individual patient data; proof of principle study.

High-quality research in hand surgery is increasingly important. A vital component is national and international multicenter collaborative research because of better generalizability and larger sample sizes. However, sharing patient data between centers can be hampered by regulations and privacy issues or reluctance to share patient data. Therefore, in this paper, we illustrate an approach for collaborative clinical research without sharing patient data while obtaining similar outcomes. To illustrate that this collaborative clinical research approach without sharing patient data leads to similar outcomes compared to aggregating all individual patient data in one database, we simulate an approach of performing meta-analyses on summary statistics of individual-center data. In the simulation, we compare the results to conventional analyses in an existing multicenter database of patients treated for Dupuytren's disease at three different centers with either limited fasciectomy (LF) or needle aponeurotomy (PNF). We share example data and all analysis code in a public GitHub Library. We found similar results for the meta-analysis approach without sharing individual patient data as in the conventional approach for 1) the proportion of patients treated for recurrences, 2) the Total MHQ score after both treatments, 3) the comparison of Total MHQ score after both treatments, and 4) the comparison of both treatments when correcting for confounders with regression analysis. CLINICAL SIGNIFICANCE: We illustrate how collaborative studies can be performed without sharing individual patient data while obtaining similar results as with conventional analyses. This approach can help speed up collaborative research without losing precision in outcome analysis.

Return to Usual Work Following an Ulnar Shortening Osteotomy: A Sample of 111 Patients.

PURPOSE: The primary aim of this study was to analyze the median time until patients performed their usual work following an ulnar shortening osteotomy (USO). The secondary aim was to identify factors influencing the median time until return to their usual work. METHODS: We used a retrospective cohort of patients with ongoing data collection from our institution in the Netherlands. Patients with paid employment who underwent USO were invited to complete a return-to-work questionnaire at 6 weeks, 3 months, 6 months, and 12 months after surgery. The probability of and median time until return to usual work were assessed using an inverted Kaplan-Meier analysis. Factors influencing the return to usual work were evaluated using multivariable Cox proportional hazard regression. RESULTS: In total, 111 patients who underwent USO were included, with a mean age of 46 years. The probability of returning to usual work in the first year was 92%, and the median time was 12 weeks. The type of work was independently associated with a return to work, with median times of 8, 12, and 14 weeks for light, moderate, and heavy physical work, respectively. We did not find differences in return to usual work based on age, sex, duration of complaints until surgery, treatment side, smoking status, the preoperative Patient-Rated Wrist Evaluation score, or whether the osteotomy was performed freehand or with an external cutting device. CONCLUSIONS: Half of the patients that underwent USO fully performed their usual work by 12 weeks following surgery. We found that 92% of the patients performed their usual work within 1 year after surgery. We found a large variation in the time until a return to work based on the type of work. Surgeons can use this data to inform patients on the rehabilitation phase after USO. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Long-term patient-reported outcomes for open surgery of the triangular fibrocartilage complex.

AIMS: Studies on long-term patient-reported outcomes after open surgery for triangular fibrocartilage complex (TFCC) are scarce. Surgeons and patients would benefit from self-reported outcome data on pain, function, complications, and satisfaction after this surgery to enhance shared decision-making. The aim of this study is to determine the long-term outcome of adults who had open surgery for the TFCC. METHODS: A prospective cohort study that included patients with open surgery for the TFCC between December 2011 and September 2015. In September 2020, we sent these patients an additional follow-up questionnaire, including the Patient-Rated Wrist Evaluation (PRWE), to score satisfaction, complications, pain, and function. RESULTS: A total of 113 patients were included in the analysis. At ≥ 60 months after an open TFCC reinsertion, we found a mean PRWE total score of 19 (SD 21), a mean PRWE pain score of 11 (SD 11), and a PRWE function score of 9 (SD 10). The percentage of patients obtaining minimum clinically important difference rose from 77% at 12 months to 83% at more than 60 months (p < 0.001). Patients reported fewer complications than surgeons, and overall complication rate was low. CONCLUSION: Outcomes of patient-reported pain, function scores, and satisfaction are improved five years after open surgery for the TFCC. Cite this article: Bone Jt Open 2021;2(11):981-987.

Closing the loop: a 10-year experience with routine outcome measurements to improve treatment in hand surgery.

Routine outcome measurements as a critical prerequisite of value-based healthcare have received considerable attention recently. There has been less attention for the last step in value-based healthcare where measurement of outcomes also leads to improvement in the quality of care. This is probably not without reason, since the last part of the learning cycle: 'Closing the loop', seems the hardest to implement.The journey from measuring outcomes to changing daily care can be troublesome. As early adopters of value-based healthcare, we would like to share our 10 years of experience in this journey.Examples of feedback loops are shown based on outcome measurements implemented to improve our daily care process as a focused hand surgery and hand therapy clinic.Feedback loops can be used to improve shared decision making, to monitor or predict treatment progression over time, for extreme value detection, improve journal clubs, and surgeon evaluation.Our goal as surgeons to improve treatment should not stop at the act of implementing routine outcome measurements.We should implement routine analysis and routine feedback loops, because real-time performance feedback can accelerate our learning cycle.

Return to Work and Associated Costs after Treatment for Dupuytren's Disease.

BACKGROUND: Return to work is potentially an important factor in assessing the success of treatment. However, little is known about the return to work after treatment for Dupuytren's contracture. Therefore, the primary aim of this study was to assess return to work after limited fasciectomy and percutaneous needle fasciotomy. METHODS: Patients who underwent either a limited fasciectomy or percutaneous needle fasciotomy were invited to complete a return-to-work questionnaire at 6 weeks, 3 months, 6 months, and 12 months postoperatively. Median time to return to work was assessed using inverted Kaplan-Meier curves, and hazard ratios were calculated with Cox regression models. Finally, a cost analysis was carried out using the human capital method to determine indirect costs associated with loss of productivity. RESULTS: The authors included 2698 patients in the study, of which 53 percent were employed at intake and included in the follow-up. After 1 year of follow-up, 90 percent of the patients had returned to work. Median time to return to work was 2 weeks after limited fasciectomy and within days after percutaneous needle fasciotomy. Furthermore, physically strenuous work, female sex, and higher age were associated with a longer time to return to work. Lost productivity per patient was estimated at €2614.43. CONCLUSIONS: The majority of patients returned to work after treatment for Dupuytren's disease. Return to work is much faster after percutaneous needle fasciotomy compared to limited fasciectomy. These findings can be used for more evidence-based preoperative counseling with patients with Dupuytren's disease.

Are Patient Expectations and Illness Perception Associated with Patient-reported Outcomes from Surgical Decompression in de Quervain's Tenosynovitis?

BACKGROUND: Psychological factors such as depression, pain catastrophizing, kinesiophobia, pain anxiety, and more negative illness perceptions are associated with worse pain and function in patients at the start of treatment for de Quervain's tenosynovitis. Longitudinal studies have found symptoms of depression and pain catastrophizing at baseline were associated with worse pain after treatment. It is important to study patients opting for surgery for their condition because patients should choose surgical treatment based on their values rather than misconceptions. Psychological factors associated with worse patient-reported outcomes from surgery for de Quervain's tenosynovitis should be identified and addressed preoperatively so surgeons can correct any misunderstandings about the condition. QUESTION/PURPOSE: What preoperative psychosocial factors (depression, anxiety, pain catastrophizing, illness perception, and patient expectations) are associated with pain and function 3 months after surgical treatment of de Quervain's tenosynovitis after controlling for demographic characteristics? METHODS: This was a prospective cohort study of 164 patients who underwent surgery for de Quervain's tenosynovitis between September 2017 and October 2018 performed by 20 hand surgeons at 18 centers. Our database included 326 patients who underwent surgery for de Quervain's tenosynovitis during the study period. Of these, 62% (201 of 326) completed all baseline questionnaires and 50% (164 of 326) also completed patient-reported outcomes at 3 months postoperatively. We found no difference between those included and those not analyzed in terms of age, sex, duration of symptoms, smoking status, and workload. The mean ± SD age of the patients was 52 ± 14 years, 86% (141 of 164) were women, and the mean duration of symptoms was 13 ± 19 months. Patients completed the Patient-Rated Wrist Evaluation (PRWE), the VAS for pain and function, the Patient Health Questionnaire for symptoms of anxiety and depression, the Pain Catastrophizing Scale, the Credibility/Expectations Questionnaire, and the Brief Illness Perceptions questionnaire at baseline. Patients also completed the PRWE and VAS for pain and function at 3 months postoperatively. We used a hierarchical multivariable linear regression model to investigate the relative contribution of patient demographics and psychosocial factors to the pain and functional outcome at 3 months postoperatively. RESULTS: After adjusting for demographic characteristics, psychosocial factors, and baseline PRWE score, we found that only the patient's expectations of treatment and how long their illness would last were associated with the total PRWE score at 3 months postoperatively. More positive patient expectations of treatment were associated with better patient-reported pain and function at 3 months postoperatively (ß = -2.0; p < 0.01), while more negative patient perceptions of how long their condition would last were associated with worse patient-reported pain and function (timeline ß = 2.7; p < 0.01). The final model accounted for 31% of the variance in the patient-reported outcome at 3 months postoperatively. CONCLUSION: Patient expectations and illness perceptions are associated with patient-reported pain and functional outcomes after surgical decompression for de Quervain's tenosynovitis. Addressing misconceptions about de Quervain's tenosynovitis in terms of the consequences for patients and how long their symptoms will last should allow patients to make informed decisions about the treatment that best matches their values. Prospective studies are needed to investigate whether addressing patient expectations and illness perceptions, with decision aids for example, can improve patient-reported pain and function postoperatively in those patients who still choose surgery for de Quervain's tenosynovitis. LEVEL OF EVIDENCE: Level III, therapeutic study.

Patient-reported outcomes and function after reinsertion of the triangular fibrocartilage complex by open surgery.

AIMS: Patients with a triangular fibrocartilage complex (TFCC) injury report ulnar-sided wrist pain and impaired function. The surgical procedure of TFCC reinsertion aims to improve function in patients with this injury in whom conservative treatment has failed. The purpose of this study was to investigate the outcomes of open TFCC reinsertion. METHODS: The study involved 274 patients who underwent open repair of the TFCC between December 2013 and December 2018. The patients completed the Patient-Rated Wrist Evaluation (PRWE) questionnaire, and scored pain and function using a visual analogue scale (VAS). Range of motion (ROM) was assessed by experienced hand therapists. RESULTS: Clinically significant improvements were reported in pain, function, and grip strength in 220 patients (80%) three and 12 months postoperatively. CONCLUSION: These data will help surgeons to make decisions about the outcomes of open repair of the TFCC and to counsel patients appropriately.

Prognostic Factors in Open Triangular Fibrocartilage Complex (TFCC) Repair.

Purpose: Patients with triangular fibrocartilage complex (TFCC) injury report ulnar-sided wrist pain and impaired function. Open TFCC repair aims to improve the condition of these patients. Patients have shown reduction in pain and improvement in function at 12 months after surgery; however, results are highly variable. The purpose of this study was to relate patient (eg, age and sex), disease (eg, trauma history and arthroscopic findings), and surgery factors (type of bone anchor) associated with pain and functional outcomes at 12 months after surgery. Methods: This study included patients who underwent an open TFCC repair between December 2011 and December 2018 in various Xpert Clinics in the Netherlands. All patients were asked to complete Patient-Rated Wrist Evaluation (PRWE) questionnaires at baseline as well as at 12 months after surgery. Patient, disease, and surgery factors were extracted from digital patient records. All factors were analyzed by performing a multivariable hierarchical linear regression. Results: We included 274 patients who had received open TFCC repair and completed PRWE questionnaires. Every extra month of symptoms before surgery was correlated with an increase of 0.14 points on the PRWE total score at 12 months after surgery. In addition, an increase of 0.28 points in the PRWE total score at 12 months was seen per extra point of PRWE total score at baseline. Conclusions: Increased preoperative pain, less preoperative function, and a longer duration of complaints are factors that were associated with more pain and less function at 12 months after open surgery for TFCC. This study arms surgeons with data to predict outcomes for patients undergoing open TFCC repair. Type of study/level of evidence: Prognostic II.

Factors affecting return to work after surgical treatment of trapeziometacarpal joint osteoarthritis.

This study aimed to identify factors contributing to the timing of return to work after surgical treatment of trapeziometacarpal joint osteoarthritis and to calculate the costs of lost productivity. We included 627 patients with paid employment who underwent trapeziectomy and ligament reconstruction with tendon interposition. Time to return to work was measured through filling online questionnaires and analysed using survival analysis at 6 weeks and 3, 6 and 12 months after the surgery. Patients also filled in the Michigan Hand Outcomes Questionnaire. Costs of lost productivity were calculated using the human capital method. After 1 year, 78% of the patients returned to work. The median time to return to work was 12 weeks. Factors that significantly affected the time to return to work were occupational intensity (light, moderate or heavy physical labour), whether the dominant hand was treated and the Michigan Hand Outcomes Questionnaire work score and hand function score of the unoperated side at baseline. The costs of lost productivity were estimated at €11,000 on the patient level, resulting in €16.8 million on the Dutch population level per year.Level of evidence: II.

Routine Health Outcome Measurement: Development, Design, and Implementation of the Hand and Wrist Cohort.

Routine measurement of outcome of clinical care is increasingly considered important, but implementation in practice is challenging. This article describes (1) how the authors created and implemented a routine outcome measurement cohort of patients with hand and wrist conditions and (2) how these data are used to improve the quality of care and facilitate scientific research. Starting in 2011, routine outcome measurement was implemented at all practice sites (currently 22) of a specialized treatment center for hand and wrist conditions across The Netherlands. The authors developed five "measurement tracks," including measurements administered at predetermined time points covering all hand and wrist disorders and treatments. An online system automatically distributes measurements among patients, which can be accessed by health care professionals. Using this system, the total number of yearly assigned tracks increased up to over 16,500 in 2018, adding up to 85,000 tracks in 52,000 patients in total. All surgeons, therapists, and other staff have direct access to individual patient data and patients have access to their treatment information using a secure patient portal. The data serve as a basis for studies on, among others, comparative effectiveness, prediction modeling, and clinimetric analyses. In conclusion, the authors present the design and successful implementation of a routine outcome measurement system that was made feasible using a highly automated data collection infrastructure, tightly linked to the patient journey and the workflow of health care professionals. The system serves not only as a tool to improve care but also as a basis for scientific research studies.

Three-ligament tenodesis for chronic scapholunate injuries: short-term outcomes in 203 patients.

In this cohort study, we report on short-term outcomes of 203 patients (203 wrists) who underwent scapholunate ligament reconstruction using a three-ligament tenodesis technique between December 2013 and December 2017. Patients completed the Patient Rated Wrist Evaluation questionnaire and a visual analogue scale for pain online before surgery and at 3 months and 1 year after surgery. We also measured the range of movement before surgery, in 150 patients 3 months after surgery, and in 90 patients 1 year after surgery. The patients reported clinically significant improvements in both pain and function postoperatively, with continuing improvement at both 3 and 12 months. We conclude that the short-term outcomes of this procedure are generally good in term of patients' function, satisfaction, and pain relief, but about 20% of the operated wrists did not improve. Our data may help patients and surgeons in joint decision-making regarding treatment for chronic scapholunate injuries. Level of evidence: III.
