Small Joint Denervation of the Hand and Thumb Base: History, Anatomy, Technique, and Outcomes.

Painful arthritis of the small joints of the hand is a common condition affecting older adults, with distal interphalangeal joint and thumb carpometacarpal joint being the two most common locations. Younger adults may also develop painful arthritis after trauma and with inflammatory arthropathy. Traditional surgical approaches address the structure of the joints with either arthrodesis or arthroplasty with or without an implant. In recent decades, denervation has been reported as an alternative treatment for painful small joints that are mobile and stable. Publications on denervation often report faster surgery and recovery times than traditional surgeries that manipulate the small joint bony structures. This article reviews the history, anatomy, surgical techniques, and outcomes of denervation of the small joints of the hand.

Total joint arthroplasty versus trapeziectomy in the treatment of trapeziometacarpal joint arthritis: a randomized controlled trial.

The aim of this double anonymized, randomized controlled trial was to determine whether total joint arthroplasty has superior outcomes than trapeziectomy 1 year after surgery for trapeziometacarpal osteoarthritis. A total of 62 women aged 40 years and older, scheduled for surgery for stage II or III osteoarthritis of the trapeziometacarpal joint, were included and randomized to trapeziectomy or total joint arthroplasty. The primary outcome was the total score of the Michigan Hand Outcomes Questionnaire. Secondary outcomes were the Michigan Hand Outcomes Questionnaire subscale scores, Disability of the Arm, Shoulder and Hand Questionnaire, active range of motion, strength, return to work, patient satisfaction and complications. Data were collected at baseline and at 3 and 12 months. At 1 year, we found no superiority of total joint arthroplasty over trapeziectomy regarding the total score of the Michigan Hand Outcomes Questionnaire. The total joint arthroplasty did show a significant advantage in strength and range of motion.Level of evidence: I.

Test-retest Reliability and Construct Validity of the Satisfaction with Treatment Result Questionnaire in Patients with Hand and Wrist Conditions: A Prospective Study.

BACKGROUND: A patient's satisfaction with a treatment result is an important outcome domain as clinicians increasingly focus on patient-centered, value-based healthcare. However, to our knowledge, there are no validated satisfaction metrics focusing on treatment results for hand and wrist conditions. QUESTIONS/PURPOSES: Among patients who were treated for hand and wrist conditions, we asked: (1) What is the test-retest reliability of the Satisfaction with Treatment Result Questionnaire? (2) What is the construct validity of that outcomes tool? METHODS: This was a prospective study using two samples: a test-retest reliability sample and a construct validity sample. For the test-retest sample, data collection took place between February 2020 and May 2020, and we included 174 patients at the end of their treatment with complete baseline data that included both the primary test and the retest. Test-retest reliability was evaluated with a mean time difference of 7.2 ± 1.6 days. For the construct validity sample, data collection took place between January 2012 and May 2020. We included 3742 patients who completed the Satisfaction with Treatment Result Questionnaire, VAS, and the Net Promotor Score (NPS) at 3 months. Construct validity was evaluated using hypothesis testing in which we correlated the patients' level of satisfaction to the willingness to undergo the treatment again, VAS scores, and the NPS. We performed additional hypothesis testing on 2306 patients who also completed the Michigan Hand Outcomes Questionnaire (MHQ). Satisfaction with the treatment result was measured as the patients' level of satisfaction on a 5-point Likert scale and their willingness to undergo the treatment again under similar circumstances. RESULTS: We found high reliability for level of satisfaction measured on Likert scale (intraclass correlation coefficient 0.86 [95% CI 0.81 to 0.89]) and almost-perfect agreement for both level of satisfaction measured on the Likert scale (weighted kappa 0.86 [95% CI 0.80 to 0.91]) and willingness to undergo the treatment again (kappa 0.81 [95% CI 0.70 to 0.92]) of the Satisfaction with Treatment Result Questionnaire. Construct validity was good to excellent as seven of the eight hypotheses were confirmed. In the confirmed hypotheses, there was a moderate-to-strong correlation with VAS pain, VAS function, NPS, MHQ pain, and MHQ general hand function (Spearman rho ranged from 0.43 to 0.67; all p < 0.001) and a strong to very strong correlation with VAS satisfaction and MHQ satisfaction (Spearman rho 0.73 and 0.71; both p < 0.001). The rejected hypothesis indicated only a moderate correlation between the level of satisfaction on a 5-point Likert scale and the willingness to undergo the treatment again under similar circumstances (Spearman rho 0.44; p < 0.001). CONCLUSION: The Satisfaction with Treatment Result Questionnaire has good-to-excellent construct validity and very high test-retest reliability in patients with hand and wrist conditions. CLINICAL RELEVANCE: This questionnaire can be used to reliably and validly measure satisfaction with treatment result in striving for patient-centered care and value-based healthcare. Future research should investigate predictors of variation in satisfaction with treatment results.

Extracorporal shock wave therapy for the treatment of arthrodesis non-unions.

INTRODUCTION: Non-union is a regular complication of arthrodeses. Standard treatment includes revision surgery with frequent need for re-revision due to persistent non-union. Particularly patients with concomitant diseases are at risk of secondary complications. There is a need for evaluation of alternative treatment options. The aim of this study is to provide first evidence on union-rate and pain course after focussed extracorporeal shock-wave therapy of arthrodesis non-unions. PATIENTS AND METHODS: In a retrospective single-centre study, 25 patients with non-union following arthrodesis received one session of focussed extracorporeal shock-wave therapy (energy flux density 0.36 mJ/mm2, 3000 impulses, 23 kV, 4 Hz). Radiographic and clinical results were recorded 6, 12 and 24 weeks after treatment. RESULTS: 24 patients were followed-up. After 24 weeks arthrodeses of the hand healed in 80%, of the upper ankle in 50%, of subtalar joint in 27.2% and of the midfoot in 0% of the cases. Pain decreased from 4.8 (± 2.8) points on the visual analogue scale to 3.4 (± 2.3), 2.9 (± 2.5) and 2.4 (± 2.8) points after 6, 12 and 24 weeks, respectively (p < 0.0001). CONCLUSION: Our data indicate that the effect of focussed, high-energy shock wave therapy depends on body region and is effective for the treatment of non-unions of the hand as well as for pain relief. LEVEL OF EVIDENCE: Level IV.

Bone and joint infections of the hand.

BACKGROUND: Little guidance is currently available for standardized diagnostic protocols and therapeutic recommendations for bone and joint infections (BJIs) of the hand. OBJECTIVES: To summarize the available data in the scientific English-language literature on the diagnosis and treatment of native BJIs of the hand. To illustrate these concepts from a narrative point of view in areas where there is lack of evidence. SOURCES: We performed a systematic PubMed and Internet search of studies that investigated hand BJIs in adult patients. CONTENT: Few studies have systematically investigated and validated diagnostic concepts, classifications or surgical treatment protocols. Most concepts derive from traditional intra-institutional experience, expert opinions and extrapolations from infections in large joints and long bones. Similarly, there is no uniformly accepted infection definition of BJIs of the hand. The best-documented literature is available for microbiological findings and antibiotic treatment duration in uncomplicated native joint arthritis of the fingers. Retrospective studies and one prospective randomized trial suggest that post-surgical targeted antibiotic therapy of 2 weeks results in a microbiological cure rate of ≥88%. IMPLICATIONS: Studies on diagnostic workup and infection definition and classification are urgently needed to compare inter-institutional outcome results and generate guidelines for the best patient care. For uncomplicated pyogenic arthritis of native joints, current evidence suggests that a 2-week course of antibiotic therapy following surgery cures the infection.

[Current Options of Rheumatosurgery of the Hand and Wrist]. / Soucasné moznosti revmatochirurgie zápestí a ruky.

Rheumatosurgery is a discipline managing the symptoms of rheumatoid arthritis of the musculoskeletal system. In a vast number of patients this disease starts in the wrist and hand. The portfolio of surgical procedures performed on the skeleton and soft tissues in these regions can be divided into two groups that, however, often times overlap in practice. Commonly, a combination of these surgical interventions is used. The surgical management should commence with prophylactic interventions that aim to slow down the development of rheumatoid deformities. These are followed by reconstructive surgery which shall manage the already developed rheumatoid deformities and their complications. The prophylactic interventions include early and late synovectomy, peritenosynovectomy, tenodeses, tendon transpositions and limited arthrodeses. The reconstructive surgery procedures comprise osteotomy, resection procedures, alloplasties, total arthrodesis and tendon reconstructions. Key words: rheumatoid arthritis, rheumatosurgery, hand, wrist.

Medium- and long-term outcomes for hand and wrist pyrocarbon implants.

The article reviews the techniques and surgical outcomes of arthroplasties of the metacarpophalangeal, carpometacarpal and the wrist joints. In my patients, interposition pyrocarbon implants quickly achieve functional recovery and do not deteriorate time. Bony and articular tolerances are remarkable. These implants are a valid alternative to conventional arthroplasties, such as trapeziectomies, silicone implants and total joint replacements. Because of the implant's small size, the surgery can be done through minimally invasive approaches especially for young and active patients. A technical key is to properly manage the bone surfaces of the joint and the peri-articular soft tissues to avoid early implant instability.

Radiologic Update on Arthroplasties in the Wrist and Hand.

Arthritis involving the hand and wrist can significantly impair functions of daily living. Although arthrodesis provides pain relief, it limits range of motion at the affected joint. Arthroplasty is an alternative surgical treatment for hand and wrist arthritis, providing both pain relief and restoration of a range of motion. Over the past decade, several advances have occurred in hand and wrist arthroplasty designs. This article reviews component design, normal imaging appearance, and common complications of arthroplasty used in the wrist and hand. It also introduces readers to newer arthroplasty designs.

Hand and wrist joint procedures in patients with scleroderma: a systematic review.

We aimed to examine if joint procedures in hands and wrists of patients with scleroderma could be performed without major morbidity and conducted a systematic review of the literature to assess this hypothesis. Studies were identified in four different databases; soft tissue procedures in scleroderma patients were excluded, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Seven studies out of an initial total of 203 articles were included. One-hundred and twelve scleroderma patients with a total of 402 joint procedures in the hand and wrist were identified. A low complication incidence, comparable with that of non-sclerodermic population, in terms of infection, wound healing problems, and nonunion was reported in all studies. The application of joint procedures in scleroderma hands and wrists seems to be associated with low morbidity.

Wide-Awake Wrist and Small Joints Arthroscopy of the Hand.

The minimally invasive nature of wrist and small joint arthroscopy renders it particularly suitable for the application of the wide-awake local anesthesia no tourniquet (WALANT) technique. The application of WALANT wrist and small joint arthroscopy has given surgeons the ability to visualize both static and dynamic movements of a joint, to show the pathology and discuss with the patient, and to visualize a patient's repaired structures. This reinforces confidence in surgeons and encourages patients to comply with postoperative rehabilitation.

Early referral and control of disease's flares prevent Orthopedic and Hand Surgery Indication (OHSI) in a dynamic cohort of Hispanic early rheumatoid arthritis patients.

BACKGROUND: Reconstructive joint surgery is an indicator of poor prognosis in rheumatoid arthritis (RA). Objectives of this study were to describe the incidence rate of orthopedic and hand surgery indication (OHSI) in an ongoing cohort of Hispanic early RA patients treated according to a T2T strategy and to investigate predictors. METHODS: Through February 2018, the cohort comprised 185 patients recruited from 2004 onwards, with variable follow-up, and rheumatic assessments at fixed intervals that included prospective determination of OHSI. Charts were reviewed by a single data abstractor. OHSI incidence rate was calculated. A case-control study nested within a cohort investigated the predictors; cases (OHSI patients) were paired with controls (1:4) according to age, sex and autoantibodies. A logistic regression model included baseline and cumulative (up to OHSI or equivalent) variables related to disease activity, treatment and to persistence with therapy. The IRB approved the study. RESULTS: Patients from the cohort were predominantly middle-aged (mean ± SD age: 38.5 ± 12.9 years) females (87.6%) with 5.4 ± 2.6 months of disease duration. The cohort contributed to 1538 patient-years of follow-up. Twelve patients received incidental OHSI at a follow-up of 85 ± 44.5 months. The OHSI incident global rate was 8/1000 patient-years. Longer symptom duration at cohort referral (OR: 1.313, 95%CI: 1.02-1.68, p = 0.032) and a higher number of flares/patient (OR: 1.608, 95%CI: 1.05-1.61, p = 0.015) predicted OHSI. OHSI patients had more severe flares than their counterparts, and the opposite figure was true for mild flares. CONCLUSION: Early referral for appropriate management and flare control may prevent OHSI in Hispanic recent-onset RA patients.

Characteristics and Outcome of Twenty-Nine Implant-Related Infections of the Hand and Fingers: Results from a Twelve-Year Observational Study.

BACKGROUND: Implant-related infections in hand surgery are dreaded complications, potentially leading to loss of finger joint function or amputation. Knowledge about the clinical presentation and treatment concepts of these infections is limited. The aim of this study is to present a consecutive series of patients with implant-related infections of the finger joints and wrist. PATIENTS AND METHODS: We identified 25 patients with 29 implant-related infections. Infections were categorized as osteosynthesis-related infections (ORIs) or arthroplasty-related infections (ARIs). Further categorization included early and late post-operative (four weeks or less or more than four weeks after implantation) and exogenous and hematogenous infection. RESULTS: Compared with patients with ARIs (n = 11), those with ORIs (n = 14) were predominantly male (n = 11), were younger (mean 43 vs. 65 years, p = 0.0023), had few or no comorbidities, and had an exogenous source of infection. Patients with ARIs were predominantly female with rheumatoid arthritis (n = 8) and had a hematogenous pathogenesis. Infections occurred late in 22 (88%) patients. The most commonly isolated micro-organism was Staphylococcus aureus (n = 12; 48%). All ORIs were treated with implant removal and a median antimicrobial treatment duration of 39 days (interquartile range [IQR] 28-50 days). In the ARI group, the implant was removed in three patients and exchanged in three patients (one-stage exchange in one patient, two-stage exchange in two patients). In five individuals, debridement and implant retention was performed. The median antimicrobial treatment duration for ARIs was 42 days (IQR 30-75 days). The median follow-up time was 96 days (IQR 42-258 days) and infection was cured or presumably cured in 22 patients (88%). CONCLUSION: Our series shows distinct host and clinical patterns in ORIs and ARIs, supporting this categorization. The infection prognosis in ORIs is excellent with implant removal and antimicrobial treatment. Treatment concepts in ARIs are often derived from algorithms for periprosthetic joint infections of larger joints and need to be further elucidated.

Long-term patient reported outcomes of elbow, wrist and hand surgery for rheumatoid arthritis.

AIM: A retrospective questionnaire survey was conducted to investigate the long-term outcomes of elbow, wrist and hand surgery for rheumatoid arthritis (RA). METHODS: One hundred and thirteen RA patients underwent primary elective elbow, wrist or hand surgery at our hospital between January 2002 and December 2003. To evaluate the outcomes at 10 years after surgery, the patient-reported outcomes were assessed using an original questionnaire that inquired about the site of treatment; the modified Stanford Health Assessment Questionnaire (mHAQ) was also used. RESULTS: Responses were obtained from 67 patients (98 sites). In the 10 years after surgery, the Disease Activity Score of 28 joint - erythrocyte sedimentation rate (4) and the modified Health Assessment Questionnaire scores of the patients showed significant improvement. Nearly 85% of patients were satisfied with the outcome at the surgical site. The most frequent reason for perceived improvement was 'pain relief' (all surgical sites). An 'improved appearance' was frequently reported after finger surgery and 'increased power' was frequently reported after wrist and thumb surgeries. With regard to elbow surgery, 30% of the patients were satisfied with the increase in motion and power. In contrast, approximately 20% of patients complained of decreased power around the surgical site after elbow and thumb surgeries. CONCLUSIONS: Our original patient-reported outcome assessment tool revealed that elbow, wrist and hand surgery provided long-lasting benefits in RA patients. While the efficacy differed in some of the surgical sites, pain relief was the most favorable effect. Altered medical therapy may also have impacted the patient-perceived outcomes of surgery at 10 years.

Range of motion, postoperative rehabilitation and patient satisfaction in MCP and PIP joints affected by Dupuytren Tubiana stage 1-3: collagenase enzymatic fasciotomy or limited fasciectomy? A clinical study in 52 patients.

INTRODUCTION: In Switzerland, collagenase Clostridium histolyticum therapy (CCH) for Dupuytren's disease was introduced in 2011. This study analyzes possible differences between CCH and limited fasciectomy (LF) in terms of range of motion, patient satisfaction and postoperative rehabilitation. MATERIALS AND METHODS: This retrospective study included 52 patients with Dupuytren's disease stage 1-3 according to Tubiana, treated with CCH or LF between January 2012 and December 2013. Complications were analyzed for each patient. The contracture of each treated joint measured on average at the 3 months and up to 2 years follow-up was compared with the preoperative values. The Michigan Hand score was evaluated at 2 years and the patients were asked to subjectively evaluate the outcome of the treatment and whether they would repeat it if necessary. Postoperative rehabilitation was also precisely quantified. RESULTS: 11 minor complications were reported for a complication rate of 29% in the CCH group. No major complications were reported in both groups. In the CCH group, mean MCP joint contracture was, respectively, 44° ± 20°, 9° ± 2° (gain of mobility compared to the preoperative situation 35°, P < 0.001), and 10° ± 3° (gain 34°, P < 0.001), respectively, before, at the 3 months' control and at the 2-year clinical control. In the LF group, mean MCP joint contracture was, respectively, 30° ± 21°, 2° ± 0.5° (gain 28°, P < 0.001), and 1° ± 0.5° (gain 29°, P < 0.001) for the same control periods. In the CCH group, mean PIP joint contracture was, respectively, 51° ± 21°, 18° ± 3° (gain of mobility compared to the preoperative situation 33°, P < 0.001), and 32° ± 4° (gain 19°, P < 0.001), respectively, before, at the 3 months' control and at the 2-year clinical control. In the LF group, mean PIP joint contracture was, respectively, 30° ± 20°, 2° ± 0.5° (gain of mobility compared to the preoperative situation 28°, P < 0.001), and 11° ± 4° (gain 19°, P < 0.001) for the same control periods. Outcomes were compared across the LF and CCH groups: surgery performed better than collagenase for PIP joint treatment at early (P < 0.001) and 2-year follow-up (P = 0.004) controls. However, patient satisfaction was higher in the CCH group: 92% were satisfied or very satisfied of the treatment compared to 71% in the LF group. All patients would reiterate the treatment in the CCH group if necessary compared to only 71% in the LF group. Rehabilitation was highly reduced in the CCH group compared to the LF group. CONCLUSION: In this study, surgery performed better than collagenase at early and 2-year follow-up in PIP joints and similar in MCP joints. While surgery seems to achieve better results, collagenase is considered in Switzerland as an off-the-shelf therapy that provides consistent results without scars, with shorter rehabilitation time, minor hand therapy, shorter splinting time, and applicability. LEVEL OF EVIDENCE AND STUDY TYPE: Level III.

20 years of rheumatoid hand surgery: what did I learn?

Rheumatoid arthritis is one common form of inflammatory arthritis that affects about 1% of the population. Few conditions in hand surgery have undergone such fundamental changes within the last two decades as rheumatoid arthritis has with regard to clinical presentations and treatments. This article provides a personal practice-guided review of the author's decision making and treatment for patients with rheumatoid arthritis in the past two decades.

Identifying barriers to the care of the rheumatoid hand in China: comparing attitudes of rheumatologists and hand surgeons.

AIM: In China, hand surgeons treat fewer rheumatoid arthritis (RA) patients compared to other countries. We investigated whether physician and surgeon knowledge, attitudes and practices regarding RA hand deformities reflect current evidence and may contribute to the low utilization of surgery. METHOD: We surveyed hand surgeons and rheumatologists at three tertiary hospitals in Beijing, China. Questionnaires were developed from literature and expert review to assess their knowledge, attitudes and practice patterns related to rheumatoid hand surgery. RESULTS: Thirty-five hand surgeons and 59 rheumatologists completed the survey. Roughly one-third felt that the rheumatologists and hand surgeons agree on how to manage RA hand deformities. One-fifth of rheumatologists and 29% of hand surgeons believed that drug therapy can correct hand deformities, which contradicts current evidence. Likewise, 30% and 14%, respectively, recommended surgery for early-stage hand sequelae that do not meet current indications for surgery. Over 80% of surgeons and rheumatologists had no exposure to the other specialty during training and felt their training on the treatment of rheumatoid hand deformities was inadequate. CONCLUSION: Although we found similar interspeciality disagreement in China as is seen in the United States, there appears to be less interaction through training and consultations. Our results also indicate potential deficits in training and unawareness of evidence and indications for rheumatoid hand surgery. These findings help to explain why surgery for rheumatoid hand deformities is rare in China; doctors have fewer opportunities to collaborate across specialties and may not be able to select appropriate candidates for surgery.

Nonrheumatoid Arthritis of the Hand.

Arthropathy of the hand is commonly encountered. Contributing factors such as aging, trauma, and systemic illness all may have a role in the evolution of this pathology. Besides rheumatoid arthritis, other diseases affect the small joints of the hand. A review of nonrheumatoid hand arthropathies is beneficial for clinicians to recognize these problems.

[Preclinical tests of additive materials for personified endoprostheses of hand joints]. / Doklinicheskie ispytaniia additivnykh materialov dlia izgotovleniia personifitsirovannykh éndoprotezov sustavov kisti v éksperimente.

AIM: To evaluate the biocompatibility of additive materials for personified endoprostheses of hand joints in vivo. MATERIAL AND METHODS: We tested a material based on titanium that was implanted into muscles and bone tissue in experiment on rabbits. Follow-up was 30 and 90 days. RESULTS: Implantation into muscle tissue is accompanied by reaction against foreign body followed by fibrosis without concomitant inflammation. Induction of osteogenesis and trabecular structures remodeling were detected after implantation into bone tissue. CONCLUSION: Biocompatibility of tested titanium-based material was confirmed.
