A Systematic Review on Long-Term Postsurgical Pain Outcomes; What Is the Effect of Upper Extremity Regional Anesthesia?

BACKGROUND: Chronic pain is a recognized complication of surgery, and it has been hypothesized that regional anesthesia might reduce the risk of development of chronic pain after upper extremity surgery. METHODS: A systematic literature review was performed to assess whether in patients undergoing elective upper extremity surgery (P), regional anesthesia (I), compared to general anesthesia (C), would result in lower long-term (>3 months) postoperative pain intensity (O). We included randomized and nonrandomized controlled trials (RCTs). Our primary outcome was numerical rating score or visual analogue scale for pain, at >3 months postoperatively. The Embase, Medline ALL, Web of Science Core Collections, Cochrane Central Register of Controlled Trials, and Google Scholar databases were searched for all reports assessing pain at >3 months after upper extremity surgery under general versus regional anesthesia. Secondary outcomes were: opioid prescription filling, complex regional pain syndrome (CRPS) incidence, the Mayo Wrist Score (MWS), and scores on the Disability of the Arm, Shoulder and Hand (DASH) questionnaire. Quality (or certainty) of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Risk-of-bias was assessed using the Cochrane tool for randomized trials (RoB 2.0) and nonrandomized trials (ROBINS-I). RESULTS: This review included 14 studies, comprising 7 RCTs and 7 nonrandomized studies. Six of the 7 studies (4 RCTs, N = 273; 2 nonrandomized studies, N = 305) using a pain score, our primary outcome, report comparable long-term postoperative pain scores after regional and general anesthesia. Six of the 7 studies using our secondary outcomes report comparable long-term outcomes in terms of opioid prescription filling (2 retrospective cohort studies [RCSs], N = 89,256), CRPS incidence (1 RCT, N = 301), MWS (1 RCT and 1 RCS, N = 215), and DASH score (1 RCT, N = 36). Comparable outcomes were reported in all 7 RCTs (N = 778) and in 5 of the 7 nonrandomized studies, comprising 5 RCSs (N = 89,608). Two prospective observational studies (POSTs), comprising 279 patients, report a statistically significant difference in outcomes, with less pain and better DASH scores after brachial plexus anesthesia. All 14 studies provided moderate to very low certainty evidence, and there was a serious risk of bias due to confounding bias in 5 of the 7 nonrandomized studies (N = 631). CONCLUSIONS: The results of this review indicate that upper extremity regional anesthesia, compared to general anesthesia, is unlikely to change pain intensity at >3 months postoperatively.

Upper Extremity Function following Transradial Percutaneous Coronary Intervention: Results of the ARCUS Trial.

Objectives: To determine the incidence of upper extremity dysfunction (UED), after a transradial percutaneous coronary intervention (TR-PCI). Background: Transradial approach (TRA) is the preferred approach for coronary interventions. However, upper extremity complications may be underreported. Methods: The ARCUS was designed as a prospective cohort study, including 502 consecutive patients admitted for PCI. Patients treated with transfemoral PCI (TF-PCI) acted as a control group. A composite score of physical examinations and questionnaires was used for determining UED. Clinical outcomes were monitored during six months of follow-up, with its primary endpoint at two weeks. Results: A total of 440 TR-PCI and 62 control patients were included. Complete case analysis (n = 330) at 2 weeks of follow-up showed that UED in the TR-PCI group was significantly higher than that in the TF-PCI group: 32.7% versus 13.9%, respectively (p=0.04). The three impaired variables most contributing to UED were impaired elbow extension, wrist flexion, and extension. Multivariate logistic regression showed that smokers were almost three times more likely to develop UED. Conclusions: This study demonstrates that UED seems to occur two times more in TR-PCI than in TF-PCI at 2 weeks of follow-up. However, no significant long-term difference or difference between the intervention arm and the contralateral arm was found at all timepoints.

Arthroscopic Synovectomy of the Wrist in Patients With Rheumatoid Arthritis: A Systematic Review of the Current Literature.

BACKGROUND: Rheumatoid arthritis (RA) of the wrist can lead to loss of wrist function and progressive joint destruction if inadequately treated. Arthroscopic synovectomy of the wrist may prove a valuable treatment for local inflammation. OBJECTIVE: The aim of this study was to perform a systematic review evaluating functional outcomes and pain following arthroscopic synovectomy of the wrist in RA patients. METHODS: A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) guidelines. MEDLINE, EMBASE, The Cochrane Library, Web of Science, and Google Scholar were searched for studies describing pain or functional outcomes following arthroscopic synovectomy of the wrist in RA patients (CRD42021270846). Risk of bias was assessed using the Methodological Index for Non-Randomized Studies. Data collection included patient characteristics, pain scores, wrist function questionnaires, secondary surgery, and complications. RESULTS: Six noncomparative cohort studies were included, with a total of 153 arthroscopic synovectomies. Disease duration of RA ranged from 32 to 89 months, and radiographic progression was mild to moderate. The Methodological Index for Non-Randomized Studies scores ranged from 8 to 10 out of 16. Mean follow-up ranged from 21 to 95 months. Improvements were seen in pooled mean visual analog scale pain score (from 7.7 to 2.2, p < 0.05), pooled mean Modified Mayo Wrist Score (from 43.3 to 70.4, p < 0.05), and the Disability of the Arm, Shoulder, and Hand (from 67.5 to 36.5, p < 0.05). Two complications occurred, and 5 patients required secondary surgery. CONCLUSIONS: There is limited evidence suggesting that arthroscopic synovectomy of the wrist improves wrist function and pain in patients with RA, with few complications. In centers with arthroscopic expertise, it can be considered as a treatment option.

Item reduction of the 39-item Rotterdam Diabetic Foot Study Test Battery using decision tree modelling.

AIMS: Pedal sensory loss due to diabetes-related neuropathy can be graded by testing static two-point discrimination (S2PD), moving two-point discrimination (M2PD), static one-point discrimination (S1PD; eg, 10-g monofilament), and vibration sense and is included in the Rotterdam Diabetic Foot (RDF) Study Test Battery. The aim of this study is to investigate if decision tree modelling is able to reduce the number of tests needed in estimating pedal sensation. METHODS: The 39-item RDF Study Test Battery (RDF-39) scores were collected from the prospective RDF study and included baseline (n = 416), first follow-up (n = 364), and second follow-up (n = 135) measurements, supplemented with cross-sectional control data from a previous study (n = 196). Decision tree analysis was used to predict total RDF-39 scores using individual test item data. The tree was developed using baseline RDF study data and validated in follow-up and control data. Spearman correlation coefficients assessed the reliability between the decision tree and original RDF-39. RESULTS: The tree reduced the number of items from 39 to 3 in estimating the RDF-39 sum score. M2PD (hallux), S2PD (first dorsal web, fifth toe), vibration sense (interphalangeal joint), and S1PD (first dorsal web, fifth toe) measurements proved to be predictive. The correlation coefficients to original scores were high (0.76 to 0.91). CONCLUSIONS: The decision tree was successful at reducing the number of RDF Test Battery items to only 3, with high correlation coefficients to the scores of the full test battery. The findings of this study aids medical decision making by time efficiently estimating pedal sensory status with fewer tests needed.

Neurofibromatosis-associated malignant peripheral nerve sheath tumors in children have a worse prognosis: A nationwide cohort study.

BACKGROUND: Malignant peripheral nerve sheath tumors (MPNST) are rare and aggressive non-rhabdomyoblastic soft-tissue sarcomas (NRSTS) in children. This study set out to investigate clinical presentation, treatment modalities, and factors associated with survival in pediatric MPNST using Dutch nationwide databases. METHODS: Data were obtained from the Netherlands Cancer Registry (NCR) and the Dutch Pathology Database (PALGA) from 1989 to 2017. All primary MPNSTs were collected. Demographic differences were analyzed between adult and pediatric (age ≤18 years) MPNST. In children, demographic and treatment differences between neurofibromatosis type 1 (NF1) and non-NF1 were analyzed. A Cox proportional hazard model was constructed for localized pediatric MPNSTs. RESULTS: A total of 70/784 MPNST patients were children (37.1% NF1). Children did not present differently from adults. In NF1 children, tumor size was more commonly large (> 5 cm, 92.3% vs 59.1%). Localized disease was primarily resected in 90.6%, and radiotherapy was administered in 37.5%. Non-NF1 children tended to receive chemotherapy more commonly (39.5% vs 26.9%). Overall, estimated five-year survival rates of localized NF1-MPNST was 52.4% (SE: 10.1%) compared with 75.8% (SE: 7.1%) in non-NF1 patients. The multivariate model showed worse survival in NF1 patients (HR: 2.98; 95% CI, 1.17-7.60, P = 0.02) and increased survival in patients diagnosed after 2005 (HR: 0.20; 95% CI, 0.06-0.69, P = 0.01). No treatment factors were independently associated with survival. CONCLUSION: Pediatric MPNSTs have presentations similar to adult MPNSTs. In children, NF1 patients present with larger tumors, but are treated similarly to non-NF1 MPNSTs. In localized pediatric MPNST, NF1 is associated with worse survival. Promisingly, survival has increased for pediatric MPNSTs after 2005.

Treatment of malignant peripheral nerve sheath tumors in pediatric NF1 disease.

BACKGROUND: Malignant peripheral nerve sheath tumors (MPNSTs) are rare yet highly aggressive soft tissue sarcomas. Children with neurofibromatosis type 1 (NF1) have a 10% lifetime risk for development of MPNST. Prognosis remains poor and survival seems worse for NF1 patients. METHODS: This narrative review highlights current practices and pitfalls in the management of MPNST in pediatric NF1 patients. RESULTS: Preoperative diagnostics can be challenging, but PET scans have shown to be useful tools. More recently, functional MRI holds promise as well. Surgery remains the mainstay treatment for these patients, but careful planning is needed to minimize postoperative morbidity. Functional reconstructions can play a role in improving functional status. Radiotherapy can be administered to enhance local control in selected cases, but care should be taken to minimize radiation effects as well as reduce the risk of secondary malignancies. The exact role of chemotherapy has yet to be determined. Reports on the efficacy of chemotherapy vary as some report lower effects in NF1 populations. Promisingly, survival seems to ameliorate in the last few decades and response rates of chemotherapy may increase in NF1 populations when administering it as part of standard of care. However, in metastasized disease, response rates remain poor. New systemic therapies are therefore desperately warranted and multiple trials are currently investigating the role of drugs. Targeted drugs are nevertheless not yet included in first line treatment. CONCLUSION: Both research and clinical efforts benefit from multidisciplinary approaches with international collaborations in this rare malignancy.

Development of grading scales of pedal sensory loss using Mokken scale analysis on the Rotterdam Diabetic Foot Study Test Battery data.

INTRODUCTION: Loss of sensation due to diabetes-related neuropathy often leads to diabetic foot ulceration. Several test instruments are used to assess sensation, such as static and moving 2-point discrimination (S2PD, M2PD), monofilaments, and tuning forks. METHODS: Mokken scale analysis was applied to the Rotterdam Diabetic Foot Study data to select hierarchies of tests to construct measurement scales. RESULTS: We developed 39-item and 31-item scales to measure loss of sensation for research purposes and a 13-item scale for clinical practice. All instruments were strongly scalable and reliable. The 39 items can be classified into 5 hierarchically ordered core clusters: S2PD, M2PD, vibration sense, monofilaments, and prior ulcer or amputation. DISCUSSION: Guided by the presented scales, clinicians may better classify the grade of sensory loss in diabetic patients' feet. Thus, a more personalized approach concerning individual recommendations, intervention strategies, and patient information may be applied.

Regional anaesthesia is associated with less patient satisfaction compared to general anaesthesia following distal upper extremity surgery: a prospective double centred observational study.

BACKGROUND: Patient satisfaction is a well-established indicator to evaluate the quality of medical care and there is an increasing support for the use of patient-reported experience measures (PREMs) to evaluate satisfaction. To anesthetize the upper limb for surgery, both general and regional plexus anaesthesia are appropriate techniques. However, the best technique in the anaesthesiologist's perspective might not necessarily result in the highest patient satisfaction. The aim of this study is to investigate patient satisfaction following general and regional anaesthesia, and to identify areas where anaesthesiologists can focus on improving patient care. METHODS: Patients scheduled for elective distal upper extremity surgery under either general or regional plexus anaesthesia were prospectively included. On the first postoperative day, patient satisfaction and main reason for dissatisfaction with the anaesthesia technique were investigated during a telephone interview. RESULTS: Of the 243 patients included in the current study, 79.8% report being "fully satisfied" with their anaesthesia technique. 32.1% of the patients who received regional anaesthesia reported not feeling "fully satisfied". This figure is 5.5% following general anaesthesia. Main reason for dissatisfaction following regional anaesthesia are reported as "insufficient anaesthesia prior to surgery", and "the discomfort of having a long-lasting insensate extremity postoperatively". CONCLUSIONS: Following regional plexus anaesthesia, a third of the patients are not "fully satisfied". To optimize patient satisfaction following regional anaesthesia techniques, we advocate stronger focus on patient counselling preoperatively, addressing the issues of block failure and prolonged postoperative sensory and motor block.

Diagnostic Criteria for Symptomatic Neuroma.

INTRODUCTION: After nerve injury, disorganized or incomplete nerve regeneration may result in a neuroma. The true incidence of symptomatic neuroma is unknown, and the diagnosis has traditionally been made based on patient history, symptoms, physical examination, and the anatomic location of pain, along with response to diagnostic injection. There are no formally accepted criteria for a diagnosis of neuroma. MATERIALS AND METHODS: A literature search was performed to identify articles related to neuroma: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed and Pubmed, Embase, and the Cochrane Library were searched for all relevant articles pertaining to neuroma. Articles were screened by title and abstract for relevance. If an article was considered potentially relevant, the full article was reviewed. After consideration, 50 articles were included in this systematic review. RESULTS: No previous articles directly addressed diagnostic criteria for symptomatic neuroma. Factors related to neuroma diagnosis gleaned from previous studies include pain and cold intolerance (patient history), positive Tinel sign or diminished 2-point discrimination (physical examination findings), response to diagnostic nerve block, and presence of neuroma on diagnostic imaging (ultrasound or magnetic resonance imaging). Based on literature review, the importance and number of references, as well as clinical experience, we propose criteria for diagnosis of symptomatic neuroma. To receive a diagnosis of symptomatic neuroma, patients must have (1) pain with at least 3 qualifying "neuropathic" characteristics, (2) symptoms in a defined neural anatomic distribution, and (3) a history of a nerve injury or suspected nerve injury. In addition, patients must have at least 2 of the following 4 findings: (1) positive Tinel sign on examination at/along suspected nerve injury site, (2) tenderness/pain on examination at/along suspected nerve injury site, (3) positive response to a diagnostic local anesthetic injection, and (4) ultrasound or magnetic resonance imaging confirmation of neuroma. CONCLUSIONS: The diagnosis of neuroma is based on a careful history and physical examination and should rely on the proposed criteria for confirmation. These criteria will be helpful in more precisely defining the diagnosis for clinical and research purposes.

Patient Perspectives on Decision Making for Carpal Tunnel Syndrome.

PURPOSE: Interventions that improve a patient's understanding of the problem and their options might reduce surgeon-to-surgeon variation, activate healthier patient behaviors and mindset, and optimize stewardship of resources while improving quality of care. Patients with carpal tunnel syndrome (CTS) have more uncertainty about which course of action to take (so-called decision conflict) than hand surgeons. We studied patient preferences regarding shared decision making (SDM) for different parts of the treatment for CTS. We assessed the following hypotheses: (1) Younger age does not correlate with a preference for greater involvement in decisions; (2) Demographic and socioeconomic factors are not independently associated with (A) preferences for decision making (separated into preoperative, operative, postoperative, and the full SDM scale) and (B) the Control Preference Scale; (3) the SDM scale does not correlate with the Control Preference Scale. METHODS: We prospectively invited 113 new and postoperative patients with CTS to participate in the study. We recorded their demographics and they completed the SDM scale and the Control Preference Scale. RESULTS: The full SDM scale and all subsets showed a patient preference toward sharing the decisions for treatment with the surgeon with a moderate tendency toward patients wanting more surgeon involvement in decision making. On multivariable analysis, having commercial insurance compared with Medicare was independently associated with a preference for less surgeon involvement (ie, higher SDM scores) in decision making (regression coefficient, 0.60; 95% confidence interval, 0.03-1.2). CONCLUSIONS: Patients with CTS generally prefer to share decisions with their surgeon with a tendency for more surgeon involvement especially in the operative and postoperative period. CLINICAL RELEVANCE: Decision aids and preference elicitation tools used to ensure diagnostic and treatment decisions for CTS that are aligned with patient preferences are needed. Future studies might address the routine use of these tools on patient outcomes.

Grading the loss of sensation in diabetic patients: A psychometric evaluation of the rotterdam diabetic foot study test battery.

INTRODUCTION: Static- and moving 2-point discrimination (S2PD, M2PD), 10-g monofilaments- and tuning fork are validated outcome measures of clinical manifestations of diabetes-related neuropathy. No modern statistical techniques have been used to investigate how well these instruments combine to measure sensory loss. METHODS: To grade sensory loss at the feet, we fitted parametric forms of Item Response Theory models to the data of these instruments. RESULTS: The fit statistics indicate that the loss of sensation is gradable, with readily available instruments. S2PD and M2PD are lost first, followed by vibration sense, the 10-g monofilament and the ability to feel a cold stimulus. CONCLUSIONS: This test battery appears to provide sound measurement properties in a group of diabetic patients with diverse amounts of sensory loss. This approach may be used in clinical practice to grade sensory loss reliably and quickly, with instruments that are easy to use. Muscle Nerve 58: 559-565, 2018.

Normative data for cutaneous threshold and spatial discrimination in the feet.

INTRODUCTION: No data are available for normative values of cutaneous threshold and spatial discrimination in the feet. We developed clinically applicable reference values in relation to the nerve distributions of the feet. METHODS: We determined foot sensation in 196 healthy individuals. Cutaneous threshold (1-point static discrimination, S1PD) was tested with monofilaments (0.008 to 300 gram) and spatial discrimination (2-point static [S2PD] and moving [M2PD] discrimination) on five locations per foot. RESULTS: There was a significant age-dependent increase in S1PD, S2PD, and M2PD values (P < 0.05). No significant differences were found between both feet. S1PD values differed up to 0.8 g between genders. There were no significant differences between genders for S2PD and M2PD measurements. M2PD values were generally lower than S2PD values. CONCLUSIONS: This study provides age-related normative values for foot sensation to help clinicians assess sensory deficits in relation to aging and identify patients with underlying nerve problems.

Ultrasonographic quantification of intrinsic hand muscle cross-sectional area; reliability and validity for predicting muscle strength.

OBJECTIVE: To investigate whether ultrasonographic measurement of the cross-sectional area (CSA) of the intrinsic hand muscles can be used to predict muscle strength in a valid and reliable manner, and to determine if this method can be used for follow-up of patients with peripheral nerve injury between the wrist and elbow. DESIGN: Repeated-measures cross-sectional study. SETTING: Clinical and academic hospital. PARTICIPANTS: Healthy adults (n=31) and patients with ulnar and median nerve injuries (n=16) between the wrist and elbow who were visiting the Erasmus Medical Center or Maasstad Hospital were included in the study (N=47). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Correlation between measured muscle CSA and strength and assessment of inter- and intrarater reliability. Ultrasound and strength measurements of the intrinsic hand muscles were conducted bilaterally. To establish validity, the CSA of 4 muscles (abductor digiti minimi, first dorsal interosseus, abductor pollicis brevis, opponens pollicis) was compared with strength measurements of the same muscles conducted with the Rotterdam Intrinsic Hand Myometer. Repeated measures were conducted to assess inter- and intrarater reliability. RESULTS: The assessed CSA strongly correlated with strength measurements, with correlations ranging from 0.82 to 0.93 in healthy volunteers and from 0.63 to 0.94 in patients. Test-retest reliability showed excellent intrarater reliability (intraclass correlation coefficient range, 0.99-1.00) in patients and volunteers and good interrater reliability (intraclass correlation coefficient range, 0.88-0.95) in healthy volunteers. CONCLUSIONS: We found that ultrasound is a valid and reliable method to assess the CSA of specific muscles in the hand. Therefore, this technique could be useful to monitor muscle reinnervation in patients suffering from peripheral nerve injury as a valuable addition to strength dynamometers.

Metric properties of advanced imaging methods in osteoarthritis of the hand: a systematic review.

OBJECTIVE: To assess the value of advanced imaging techniques in the detection of hand osteoarthritis (OA) and hand OA progression. METHODS: PubMed/Medline and Embase were searched until April 2012 for studies on imaging of hand OA that presented quantitative data on validity, reliability or responsiveness. Articles presenting only data on conventional radiography (CR) were excluded. Methodological quality was assessed by the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) checklist for validity, the Quality Appraisal of Reliability Studies (QAREL) for reliability and the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) for responsiveness. RESULTS: Of 627 citations, 25 studies on ultrasonography (US), MRI or scintigraphy were included. No studies on CT, positron emission tomography or single photon emission CT met our eligibility criteria. Validity was generally assessed against healthy controls, CR or clinical examination. Overall, US and MRI detected more disease than CR and found significant differences between patients and healthy controls. Scintigraphy detected fewer pathological joints than CR. Intra- and inter-reader reliability varied for US (κ=0.01-1.0) and MRI (κ=0.15-0.84 and intraclass correlation coefficient=0.21-0.99) and was good for scintigraphy (κ=0.61-0.84). There were no responsiveness studies for MRI. US responsiveness studies showed a reduction of soft-tissue changes after treatment which correlated with decrease in pain (r=0.7-0.8). For scintigraphy, scores decreased over time while CR showed progression of hand OA. CONCLUSIONS: MRI and US seem to be the most promising candidates for early detection of hand OA and for future use in clinical trials. However, further research is needed to improve scoring methods, to compare US with MRI, to confirm reliability of MRI and to further determine the responsiveness of US and MRI.

Carpal tunnel syndrome: hand surgeons, hand therapists, and physical medicine and rehabilitation physicians agree on a multidisciplinary treatment guideline­results from the European HANDGUIDE Study.

OBJECTIVE: To achieve consensus on a multidisciplinary treatment guideline for carpal tunnel syndrome (CTS). DESIGN: Delphi consensus strategy. SETTING: Systematic reviews reporting on the effectiveness of surgical and nonsurgical interventions were conducted and used as an evidence-based starting point for a European Delphi consensus strategy. PARTICIPANTS: In total, 35 experts (hand surgeons selected from the Federation of European Societies for Surgery of the Hand, hand therapists selected from the European Federation of Societies for Hand Therapy, physical medicine and rehabilitation physicians) participated in the Delphi consensus strategy. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Each Delphi round consisted of a questionnaire, analysis, and feedback report. RESULTS: After 3 Delphi rounds, consensus was achieved on the description, symptoms, and diagnosis of CTS. The experts agreed that patients with CTS should always be instructed, and instructions combined with splinting, corticosteroid injection, corticosteroid injections plus splinting, and surgery are suitable treatments for CTS. Relevant details for the use of instructions, splinting, corticosteroid injections, and surgery were described. Main factors for selecting one of the aforementioned treatment options were identified as follows: severity and duration of the disorder and previous treatments received. A relation between the severity/duration and choice of therapy was found by the experts and reported in the guideline. CONCLUSIONS: This multidisciplinary treatment guideline may help physicians and allied health care professionals to provide patients with CTS with the most effective and efficient treatment available.

Surgical technique: hemi-extensor carpi radialis brevis tenodesis for stabilizing the midcarpal joint in Ehlers-Danlos syndrome.

Patients with the hypermobility type of Ehlers-Danlos (EDS-HT) often complain of wrist pain, usually originating from subluxations. As a result of the laxity, wrist function in these patients can be highly limited. This paper presents a surgical technique that stabilizes the lunocapitate joint with the use of an extensor carpi radialis brevis strip. Five patients with confirmed EDS-HT were treated with an extensor carpi radialis brevis tenodesis for their midcarpal instability. Two patients presented with complications following surgery, one major and one minor. This paper presents a potentially satisfactory surgical solution to recurrent midcarpal instability in EDS-HT patients and demonstrates that the use of an autologous tendon might be feasible in spite of a background of abnormal collagen metabolism.

Clinical Results of Nonvascularized Metatarsal Articular Bone Grafting for Osteochondral Defects of the Radiocarpal and Distal Radioulnar Joint.

Background Treatment of post-traumatic osteochondral defects in the radiocarpal and distal radioulnar joint with nonvascularized metatarsal articular bone grafting is an option to restore the joint (cartilage) surface and wrist function. Purpose To evaluate the clinical midterm results of 10 consecutive patients who were treated with a nonvascularized metatarsal bone graft for cartilage bone defects of the lunate facet, scaphoid facet, sigmoid notch, or the radial part of the ulnar head. Patients and Methods Patients with isolated osteochondral defects of the lunate facet, scaphoid facet, sigmoid notch, or radial part of the ulnar head, respectively, as a result of wrist trauma were retrospectively identified in a prospectively collected database. The patients symptoms were limited wrist motion and/or pain. Clinical results and complications were extracted from patient's medical files and two questionnaires consisting of the Patient-Rated Wrist Evaluation and additional questions regarding patient satisfaction and return to work and/or hobby. Results Minor complications occurred in three cases and required surgery. In five cases an acceptable donor site foot morbidity was seen at 1 year. One patient was not satisfied due to persistent wrist pain despite adequate range of motion. One patient could not return to its prior work. Another patient could not resume its hobby. Conclusion Retrospective evaluation of 10 cases with resurfacing of the scaphoid facet, sigmoid notch, and/or lunate facet, or radial part of the ulnar head has shown that osseointegration was possible without a vascular pedicle to the graft in all cases with a (mean) follow-up of 5 years. This technique may become an alternative treatment when implants become less available. Level of Evidence Level III.

Clinical Results of Patients with Combined Aptis Distal Radioulnar Joint Arthroplasty and Total Wrist Arthroplasty.

Background Severely destroyed wrists can be managed by combined radiocarpal and distal radioulnar joint (DRUJ) replacement that reduces pain while mobility is ought to be reserved. The combination of these arthroplasties is rarely reported in the literature. Purpose This article describes the clinical outcomes of six consecutive patients with both total wrist and Aptis DRUJ arthroplasty with a median follow-up of 50 months (range: 18-108 months). Patients and Methods Patients with a TWA combined with an Aptis DRUJ arthroplasty were retrospectively identified. The patients were treated between 2011 and 2020. Results The flexion-extension arc was slightly decreased in three cases while forearm rotation was improved in three patients. Pain was adequately reduced in four patients and significant pain was seen in two patients. Although three of four patients could not return to previous work, all patients claimed to be satisfied with the result of the procedure. Conclusion This article demonstrates the possible feasibility of this combined arthroplasty in patients with a destroyed and unstable wrist. Level of Evidence Level III.
