Development and Validation of a Survey to Measure Patients' Expectations of Wrist Arthritis Surgery

Background  The purpose of this study was to develop and test a patient-derived expectations survey for wrist arthritis surgery. We hypothesized that preoperative patient expectations are higher in people with greater functional impairment and that postoperative fulfilment of patient expectations correlates with functional improvement. Methods  The study was conducted in four phases. Development (n = 22) Preoperatively, patients were asked open-ended questions regarding expectations of surgery. A draft survey was then assembled. Reliability (n = 35) The survey was administered twice preoperatively. Concordance was measured with weighted kappa values and intraclass correlations (ICC). Validity (n = 58) Validity was assessed by comparing responses from the Expectations Survey to the patient-rated wrist evaluation (PRWE). Responsiveness (n = 18) Responsiveness was calculated by comparing the proportion of expectations fulfilled to PRWE scores 1-year postoperatively. Results   Development Twenty-two distinct items representing the most frequent responses were utilized from the draft survey items of 1,244 expectations volunteered. Reliability Patients had high preoperative expectations of surgery (mean = 76.8); 30% had scores ≥90. Test-retest reliability was high (Cronbach α coefficients = 0.91, 0.93, ICC = 0.86). Endorsement of items = 66 to 100%; and weighted kappa values = 0.39 to 0.96. Validity Patients with greater preoperative expectations (≥63) had more pain, worse function, and worse PRWE scores than those with lower expectations. Responsiveness The proportion of fulfilled expectations was high (mean 0.80, median 0.79), and greater fulfillment (proportion > 0.80, n  = 8) was associated with better postoperative PRWE scores. Conclusion  The patient-derived expectations survey is reliable, valid, responsive, and addresses a spectrum of expectations for patients undergoing surgery for wrist arthritis. Clinical relevance Understanding patient expectations can contribute to customized care given the range of surgical choices for the arthritic wrist.

Total wrist fusion versus total wrist prosthesis: a comparative study

We present a comparative study of 41 total wrist fusions (TWFs) with contoured plate and 22 total wrist prostheses using the Universal 2™ model, with a mean follow-up of 6 years for the fusion and 6.5 years for the prosthesis. We evaluated grip strength, pain according to the visual analogue scale, functional results using the Quick Disabilities of the Arm, Shoulder and Hand and the Patient-Rated Wrist Evaluation, degree of satisfaction and complications, with no significant differences being observed in any of these variables. The results allow us to conclude that total wrist prosthesis implanted in patients with low or moderate functional demands offers medium-term functional results similar to TWF without increasing the number of complications.Level of evidence: III.

Wrist Salvage Procedures for the Treatment of Kienbock's Disease

Kienbock's disease is a progressive condition characterized by lunate collapse, carpal instability, and eventually perilunate arthritis. Etiology is likely multifactorial, including vascular and anatomic or osseus causes. In cases of advanced disease, disabling pain, limited motion, and decreased grip strength may be present. The preferred treatment options for the nonreconstructable wrist are proximal row carpectomy (PRC), total wrist arthrodesis, and total wrist arthroplasty (TWA). In the following chapter, we will discuss various surgical options for patients with advanced Kienbock's disease.

Correlation between carpal rotational alignment and postoperative wrist range of motion following total wrist arthroplasty

BACKGROUND

Although total wrist arthroplasty (TWA) has become a common treatment option for wrists with damage due to rheumatoid arthritis (RA), the optimal implant axial alignment for TWA has been inadequately studied. This study was performed to investigate the relationships between implant alignment and carpal rotational alignment and the wrist range of motion (ROM) following TWA.

METHODS

This study included 18 patients who underwent TWA using a DARTS® Total Wrist System (Teijin Nakashima Medical, Okayama, Japan) for wrist RA. Pre- and 6-month postoperative computed tomography scans were performed, including the radial volar line (Rv), capitohamate axis (CH), and Rv-CH angle in axial scans. The wrist ROM was also measured. The relationship between the Rv-CH angle and ROM was examined.

RESULTS

The mean Rv-CH angle showed significant wrist pronation from 73.0° to 83.4° postoperatively. We observed a significant positive correlation (0.58) between the postoperative Rv-CH angle and extension and a significant negative correlation (- 0.56) between the postoperative Rv-CH angle and flexion.

CONCLUSIONS

Implantation of the DARTS® TWA prosthesis resulted in pronation of the carpal axial alignment, which was correlated with postoperative wrist extension. The volar cortex of the distal radius can be a novel reference axis for adequate implant placement.

Self-identified functional limitations improve in patients with degenerative wrist arthritis after surgery

STUDY DESIGN

This is a prospective cohort pilot study.

BACKGROUND

Degenerative wrist arthritis leads to pain, loss of strength, mobility, function, and impairments in psychological well-being. Accurate assessment of functional limitations that are unique to the individual is essential for successful treatment that best meets those specific needs.

PURPOSE OF THE STUDY

To identify and determine if self-identified functional limitations improve in patients who underwent surgery for degenerative wrist arthritis.

METHODS

Patients with degenerative wrist arthritis who were scheduled for surgery were prospectively recruited (n = 14, mean age + SD = 42 + 16, 10 males, 4 females) into a pilot study that measured self-identified functional limitations and outcomes. Inclusion criteria included a diagnosis of scapholunate advanced collapse, scaphoid nonunion advanced collapse, scapholunate interosseous ligament tear, or Kienböck disease. Exclusion criteria included a history of neuromuscular disease or concomitant ipsilateral musculoskeletal injury. Data were collected during two 20-minute sessions, preoperatively and one year postoperatively, utilizing the Patient-Rated Wrist Evaluation and the Canadian Occupational Performance Measure.

RESULTS

All patients reported significant decreases (P < .001) in total pain (mean change = 17.6, SD = 8.5) and total disability (mean = 17.8, SD = 9.1) on the Patient-Rated Wrist Evaluation from presurgery to postsurgery, with a large effect size of d > 0.8. Patients also reported significant improvements (P < .001) in mean performance (mean = 3.5, SD = 1.5) and mean satisfaction (mean = 4.0, SD = 2.1) with self-identified activities on the Canadian Occupational Performance Measure, with an effect size of d > 0.8.

CONCLUSION

Patients with degenerative wrist arthritis reported significant postoperative improvement in both performance and satisfaction in self-identified activities. Consideration of patient-specified goals can inform both patients and clinicians during the surgical decision-making process and allow for more individualized care.

Universal 2™ total wrist arthroplasty: A single-surgeon 6.5-year follow-up study of 22 prostheses

Total wrist arthroplasty remains controversial, with the few studies undertaken being heterogeneous and having low patient numbers. This prospective study involved 22 Universal 2™ total wrist prostheses implanted by the same surgeon between 2003 and 2017. There were 13 women and nine men with an average age of 56 (42-69.5) years. Indications for total wrist arthroplasty were post-traumatic arthritis, rheumatoid arthritis and Kienböck's disease. The mean follow-up was 6.5 (3-17) years. Two failed implants required total wrist fusion. Postoperative pain, grip strength, QuickDASH, patient-rated wrist evaluation, and Mayo wrist scores improved significantly compared with preoperative scores. The prosthesis preserved equal or slightly greater range of motion than the preoperative range of motion, sufficient to undertake activities of daily living and improve quality of life. Postoperative radiographs 1 month after the surgery and then annually showed signs of bone deterioration in 64% of implants, most osteolysis without loosening, compatible with asymptomatic function. Although a high number of radiographic signs of implant changes were apparent in the midterm, 91% of prostheses are still in place. The long-term survival of this implant is uncertain. LEVEL OF EVIDENCE: Therapeutic IV.

Total Wrist Arthroplasty: A 10-Year Follow-Up

PURPOSE

To assess long-term implant survival in total wrist arthroplasty (TWA), comparing 4 different implants.

METHODS

In a prospective cohort of 124 patients, 136 TWAs were evaluated 5 years and 10 years after surgery. The TWAs were implanted between 2005 and 2009. The primary outcome was implant survival. Survival analysis was performed with revision and radiographic loosening as the final end point. Revision was defined as exchange of whole or parts of the prosthesis. Implant loosening was assessed using radiographic examination at the 5-year and 10-year follow-up. Secondary outcome measures included wrist range of motion, hand grip strength, visual analog scale (VAS) pain scores, and patient-related outcome measures, including Disabilities of the Arm, Shoulder, and Hand (DASH), Patient-Rated Wrist Evaluation (PRWE), and Canadian Occupational Performance Measure (COPM).

RESULTS

Total cumulative implant survival was 92% with revision as the primary end point. When including a nonrevised radiographic loose implant as a failure, total implant survival was 75%. Radiographic loosening differed significantly between the implants with a range in frequency from 0% to 37.5%. At the 10-year follow-up, assessing the nonrevised TWAs, range of motion was preserved compared with preoperative values. Significant improvement was recorded for hand grip strength, VAS pain scores, and patient-related outcome measures at the 10-year follow-up compared with preovperative values.

CONCLUSIONS

High 10-year implant survival was found when defining the primary end point as revision of any cause. When including radiographic loosening of the implant in the survival analysis, implant survival was considerably lower. However, radiographic loosening does not seem to correlate with changes in secondary outcome measures, questioning the need for revision surgery in these cases.

Functional Outcomes After Salvage Procedures for Wrist Trauma and Arthritis (Four-Corner Fusion, Proximal Row Carpectomy, Total Wrist Arthroplasty, Total Wrist Fusion, Wrist Denervation): A Review of Literature

Background:

Several salvage procedures for the arthritically destroyed wrist exist. Each of these has advantages as well as disadvantages.

Aims:

The aim of this article is to give practical insights for the clinician on: (1) biomechanical and clinical fundamentals of normal and impaired wrist motion; (2) difficulties in assessment of postoperative outcome between measured motion by the surgeon and self-reported outcome by the patient; (3) indications for each procedure; and (4) differences in functional outcome between partial and complete motion-preserving as well as complete motion-restricting salvage procedures.

Methods:

In trend, Proximal Row Carpectomy (PRC) is slightly superior over four-corner fusion (4CF) in terms of functional outcome, but the methodology-related postoperative motion is decreased for both procedures. Furthermore, PRC is easier to perform, needs lower costs, and has fewer complications than 4CF. Total Wrist Arthroplasty (TWA) has the advantage compared to PRC and 4CF that the preoperative motion values are preserved, but it is limited by decreased load-bearing capacity for the wrist. Total Wrist Fusion (TWF) is associated with a higher load-bearing capacity for the wrist than TWA, but it is limited for carrying out essential activities of daily living. Both PRC and 4CF can be combined primarily by wrist denervation. Wrist denervation alone does not impair the movement of the wrist.

Results and Conclusion:

Salvage procedures for the arthritically destroyed wrist should be detected regarding patients age- and gender-related claims in work and leisure. Not all of them can be successfully re-employed in their original occupations associated with high load-bearing conditions.

Trends and Demographics in the Utilization of Total Wrist Arthroplasty

BACKGROUND

Health disparities exist among many patient populations, with race, payer status, hospital size and access to teaching versus non-teaching hospitals potentially affecting whether certain patients have access to the benefits of total wrist arthroplasty (TWA).

METHODS

The National Inpatient Sample Database (NIS) was queried from 2001 to 2013 for TWA using the ICD-9 code 81.73. Patient-level data included age, sex, race, payer status, and year of discharge. Hospital-level data included hospital bed size, location, teaching status, and region.

RESULTS

There were 1,213 patients identified who underwent TWA between 2001 and 2013. Total number of procedures decreased from 88 TWAs in 2001 to 65 in 2013. The yearly volume ranged from 33 in 2005 to 128 in 2007. The male-female ratio was 2.5 to 1. The majority of TWA procedures were performed at urban teaching hospitals (60.8%).

CONCLUSIONS

The NIS database shows a downward trend of total wrist arthroplasty utilization. The majority of total wrist arthroplasties were performed at urban teaching hospitals indicating treatment occurs most often at academic centers of excellence.

Current European Practice in Wrist Arthroplasty

The results of wrist arthroplasty for severely destroyed and painful wrists are generally good in pain reduction, increased grip strength, and upper limb function. The wrist range of motion is usually preserved but not improved. Implant survival seems better than it was with earlier implant designs; however, there are problems of carpal component loosening. Patient selection plays an important role, requiring experience, careful patient information, and discussing the pros and cons of arthroplasty and partial or total wrist arthrodesis.

Universal 2 Wrist Arthroplasty in Rheumatoid Arthritis

Purpose  The aim of this study was to evaluate the mid- to long-term outcomes and complications in patients affected by rheumatic diseases treated with the Universal 2 (U2) total wrist arthroplasty (TWA). Methods  We reviewed, in a retrospective, noncontrolled cohort study, 22 patients affected by rheumatoid arthritis (RA), who underwent U2 total wrist replacement between March 2003 and January 2014 for the treatment of 23 rheumatoid wrists with the aim of obtaining the remission of pain and a range of motion (ROM) useful for daily activities, according to the patients' demands, as an alternative to total wrist arthrodesis. The cohort of patients included 20 females and 2 males, with a mean age of 54.9 years. Residual pain, preoperative ROM, postoperative ROM increases, grip strength, radiographic changes, long-term complications, and reasons for revision or failures were evaluated. Results  In this study, 22 patients were evaluated at a mean follow-up of 82.3 months (range: 2-12 years). All patients had good or complete pain relief, the mean visual analogue scale pain score was 0.82. The mean grip strength improved and postoperatively was 11 kg (Jamar). The mean total ROM of flexion-extension was 72.3 degrees; radial-ulnar deviation 24.9 degrees. The mean QuickDASH score of 49 and patient rate wrist/hand evaluation of 41.7 a revision surgical procedure in six cases (26%): in two cases, a carpal component revision procedure and in four cases, total implant failures requiring either conversion to a Swanson spacer or wrist joint fusion. Conclusion  TWA provides pain relief, preserves motion, and improves function in severe degenerative RA. Our results at a mid- to long-term follow-up with the U2 prosthesis were encouraging and represent, when indicated, a valid alternative to fusion which is less appealing for RA patients. Level of Evidence  Level of evidence is therapeutic IV.

Total Wrist Arthroplasty Versus Wrist Fusion: Utilization and Complication Rates as Reported by ABOS Part II Candidates

BACKGROUND

The aim of this study was to assess national trends in the utilization and complication rates of total wrist arthroplasty (TWA) and total wrist fusion (WF) as identified via review of the American Board of Orthopedic Surgery (ABOS) Part II candidate database.

METHODS

The ABOS Part II candidate database is a collection of cases reported by candidates of the ABOS Part II board certification oral exam. The ABOS database was queried for all TWA and WF cases performed from 2005 to 2014. Linear regression analyses were used to assess trends in procedure utilization. Treatment diagnoses, patient characteristics, and reported complications were also compared between the 2 treatment cohorts.

RESULTS

No significant increases in the proportion of candidates performing TWA or WF, number of TWA or WF cases, nor the number of TWA or WF cases performed per candidate performing those procedures were noted during the study period. Significantly less TWA cases were performed when compared with WF cases (68 vs 327; P = .006). Patients undergoing TWA were significantly older ( P = .005), more likely female ( P < .001), and more likely to have a diagnosis of osteoarthritis ( P = .003) than patients undergoing WF. There were no significant differences in complication rates, including postoperative infection, nerve palsy, or rate of secondary surgery, between the TWA and WF cohorts.

CONCLUSIONS

Utilization of both TWA and WF has remained unchanged among emerging career orthopedic surgeons. Although WF is performed nearly 5 times more frequently than TWA, our short-term findings suggest that TWA compares favorably with WF.

Does Total Wrist Arthroplasty for Treatment of Posttraumatic Wrist Joint Osteoarthritis in Young Patients Always Lead to Restriction of High-demand Activities of Daily Living? Case Report and Brief Review of Recent Literature

Background:

Posttraumatic ulnar carpal translocation is a very rare condition that is caused either by fracture-dislocation injury or by purely ligamentous injury of the wrist. Its prognosis is poor and development of posttraumatic pancarpal wrist joint osteoarthritis is inevitable, and options for treatment are total wrist fusion or total wrist arthroplasty.

Methods:

A 24-year-old male sustained a fracture-related injury in his left wrist that was accompanied with a second ligamentous distorsion-related injury 1 year later in the same wrist. Seven years after first injury, a posttraumatic pancarpal wrist joint osteoarthritis has developed that was caused by posttraumatic ulnar carpal translocation. The patient was treated by total wrist arthroplasty with use of the Maestro^TM Wrist Reconstructive System.

Results:

With our patient, it is unclear whether posttraumatic ulnar carpal translocation occurred either as result of the first fracture-related injury or as result of the second ligamentous distorsion-related injury or as result of both injuries. The 31-year-old patient could be reemployed completely in his original occupation as a mechanic for big agriculture machines and load his wrist with more than 10 pounds. In order to preserve motion, the patient reported that he would undergo the same total wrist arthroplasty a second time were it necessary.

Conclusion:

We report on a young male receiving total wrist arthroplasty and resulting in good restoration of his high-demand claims in activities of daily living, respectively. However, it cannot be concluded that total wrist arthroplasty is to be preferred generally over total wrist fusion in young patients. Essential prerequisite for this motion-preserving procedure is the compliance of patients.

Total Wrist Arthroplasty

Total wrist arthroplasty using current design implants has evolved into a fairly predictable procedure for rheumatoid, osteoarthritic, and posttraumatic patients. Although complications can occur, the incidence of these has dropped over the past decade with implant design modifications. The article summarizes the current use of total wrist arthroplasty and touches on issues of revision surgery, secondary fusion, complications, wrist fusion takedown, and radiolucency around implants. Technical tips are also provided for both primary and revision surgery.

An Unusual and Complicated Course of a Giant Cell Tumor of the Capitate Bone

A 51-year-old female patient presented with a carpal giant cell tumor (GCT) of the right capitate bone. The lesion was initially misdiagnosed as having an osteomyelitis. First, the diagnosis of a benign GCT was confirmed by histological examination. Second, an intralesional curettage and packing of the cavity with cancellous iliac crest bone grafts combined with a fusion of the third carpometacarpal (CMC III) joint were carried out. Third, due to a secondary midcarpal osteoarthritis and a secondary scaphoid nonunion, the CMC III joint fusion plate was removed and the midcarpal joint completely excised. Fourth, in the absence of recurrence of GCT, a four-corner fusion (4CF) with a corticocancellous iliac crest bone graft and complete excision of the scaphoid bone had to be performed. Fifth, a total wrist arthroplasty (TWA) was performed due to hardware failure of 4CF with migration of a headless compression screw into radiocarpal joint which led to erosion of articular surface of the distal radius. At the 3-year follow-up that includes a 1-year follow-up after TWA, there was no recurrence of GCT, and the TWA was not failed. The patient reported that she would have the motion-preserving TWA again.

Self-Report Measures of Hand Pain Intensity: Current Evidence and Recommendations

Successful management of problems related to the hands and upper extremities begins with a comprehensive assessment of the pain experience and related factors. Pain intensity is the domain most commonly assessed, and pain relief is often the primary goal of treatment. Because pain is a private and subjective experience, self-report is considered the gold standard of pain measurement. This article describes and discusses the strengths and weaknesses of the most commonly used self-report scales used to measure hand pain intensity, and gives recommendations to help clinicians select from among the various options for measuring the intensity of hand pain.

Total Wrist Arthroplasty: A Single-Center Study of 219 Cases With 5-Year Follow-up

PURPOSE

To assess implant survival and radiographic loosening after total wrist arthroplasty (TWA) operated at a single tertiary referral center in Sweden.

METHODS

In a prospective cohort study, we evaluated 189 consecutive patients with a TWA (219 wrists). The wrists were implanted between 2002 and 2013. The primary end point was revision for any reason. The mean follow-up period was 7 years (range, 2-13 years). In addition, radiological examination was done for evidence of prosthetic loosening 5 years postoperatively. Implant survival was estimated using the Kaplan-Meier method. Secondary outcome measures included range of motion, visual analog scale pain scores, hand grip strength, and patient-related outcome measures.

RESULTS

Cumulative implant survival after 8 years was 81% for Biax, 94% for Remotion, and 95% for Maestro implants. Radiographic loosening was present in 26% of wrists with the Biax design, 18% of those with Remotion, and 2% of those with Maestro. Visual analog scale pain scores and patient-related outcome scores improved significantly for all TWAs. Improved hand grip strength was noted for all TWAs except for the Universal 2. Range of motion improved somewhat, especially for the Biax and Maestro TWAs.

CONCLUSIONS

Good midterm to long-term results were achieved in patients undergoing TWA. Radiographic loosening did not necessarily correlate with implant survival rates, but rather to severe arthritic destruction of the wrist preoperatively. All TWA implants studied offered a high level of patient satisfaction.

Can Total Wrist Arthroplasty Be an Option for Treatment of Highly Comminuted Distal Radius Fracture in Selected Patients? Preliminary Experience with Two Cases

We present two case reports of successful primary shortening of the forearm and total wrist arthroplasty (TWA) using the new angle-stable Maestro Wrist Reconstructive System (WRS) for treatment of highly comminuted distal radius fracture in selected autonomous patients. In a 56-year-old male patient with adequate bone stock, insertion of the noncemented Maestro WRS was combined with ulnar shortening osteotomy. In an 84-year-old female patient with poor osteoporotic bone stock, insertion of the radial cemented Maestro WRS was combined with ulnar head resection. Both patients could resume their work without additional surgery after TWA. At the 1-year follow-up, there were no changes in position of either implant without signs of loosening, no impingement, and no instability of the distal radioulnar joint or the distal ulna stump. All clinical parameters (DASH score, pain through VAS, and grip strength) were satisfactory. Both patients reported that they would have the same procedure again. Further experience is needed to validate this concept.
