Comparison of Long-Term Healthcare Cost and Utilisation of Nonoperative and Surgical Management of Thumb CMC Arthritis.

Background: Thumb carpometacarpal joint (CMC) osteoarthritis is the most symptomatic hand arthritis but the long-term healthcare burden for managing this condition is unknown. We sought to compare total healthcare cost and utilisation for operative and nonoperative treatments of thumb CMC arthritis. Methods: We conducted a retrospective longitudinal analysis using a large nationwide insurance claims database. A total of 18,705 patients underwent CMC arthroplasty (trapeziectomy with or without ligament reconstruction tendon interposition) or steroid injections between 1 October 2015 and 31 December 2018. Primary outcomes, healthcare utilisation and costs were measured from 1 year pre-intervention to 3 years post-intervention. Generalised linear mixed effect models adjusted for potentially confounding factors such as the Elixhauser comorbidity score with propensity score matching were applied to evaluate the association between the primary outcomes and treatment type. Results: A total of 13,646 patients underwent treatment through steroid injections, and 5,059 patients underwent CMC arthroplasty. At 1 year preoperatively, the surgery group required $635 more healthcare costs (95% CI [594.28, 675.27]; p < 0.001) and consumed 42% more healthcare utilisation (95% CI [1.38, 1.46]; p < 0.0001) than the steroid injection group. At 3 years postoperatively, the surgery group required $846 less healthcare costs (95% CI [-883.07, -808.51], p < 0.0001) and had 51% less utilisation (95% CI [0.49, 0.53]; p < 0.0001) annually. Cumulatively over 3 years, the surgical group on average was $4,204 costlier than its counterpart secondary to surgical costs. Conclusions: CMC arthritis treatment incurs high healthcare cost and utilisation independent of other medical comorbidities. At 3 years postoperatively, the annual healthcare cost and utilisation for surgical patients were less than those for patients who underwent conservative management, but this difference was insufficient to offset the initial surgical cost. Level of Evidence: Level III (Therapeutic).

Primary trapeziectomy with Regjoint(TM), a poly-L/D-lactide spacer, a two-year follow-up study with new radiological assessment tool.

The aim of this retrospective study was to evaluate the potential bony erosion and the clinical and radiological results of primary trapeziectomy with RegjointTM interposition, in patients with peritrapezial arthritis. Data were recorded on twenty patients over a period of two years (January 2015-December 2016). On average 24 months, patients were reconvened for a post-operative evaluation (subjective evaluation of pain, function and patient satisfaction; clinical evaluation with strength and mobility measures; post-operative X-rays). On X-rays, 2 criteria were evaluated: the bony erosion and the shortening of the thumb column (trapezium+metacarpal height measure, ratio between first and second metacarpal bones, a new radiological assessment tool based on a trapezoid relationship gradation). In most patients, surgery relieved pain and offered good functional results, according to the Quick Disabilities of the Arm, Shoulder and Hand scale. Following surgery, our patients showed a subjective improvement, both in terms of pain and functional results. For plain X-ray, only 3 patients showed an osteolytic lesion (maximum of 2.8 millimeters) on the first metacarpal base. A statistically significant reduction in the thumb column height was generally observed on follow-up X-rays. However, all of these radiologic changes were present without any clinical impact. We show that the RegjointTM spacer is an available alternative in the surgical treatment of peritrapezial arthritis. We did not highlight any significant associated complications, no important adverse tissue reaction or bone erosion, no pain or functional disorder. Type of study/level of evidence Therapeutic IV.

Thumb Carpometacarpal Stabilization With a Dorsal Capsule Repair Augmented With an Internal Brace.

Optimal surgical treatment of first carpometacarpal joint instability remains a subject of debate. Consensus on thumb carpometacarpal stability originating with the dorsoradial ligamentous complex has shifted reconstruction techniques towards stabilization dorsally. We describe a dorsal stabilization technique with internal brace augmentation of the dorsoradial ligamentous complex. A single fellowship-trained hand surgeon treated 10 women, average age 34 years (range, 21 to 52 y) and 1 man, age 34 years, between 2019 and 2022. Average patient follow-up was 2 years. Patient satisfaction was high. Further trials are needed to determine whether the procedure will prevent or delay the presentation of thumb carpometacarpal arthrosis.

Cost-Utility Analysis of Thumb Carpometacarpal Resection Arthroplasty: A Health Economic Study Using Real-World Data.

PURPOSE: Knowledge about the costs and benefits of hand surgical interventions is important for surgeons, payers, and policy makers. Little is known about the cost-effectiveness of surgery for thumb carpometacarpal osteoarthritis. The objective of this study was to examine patients' quality of life and economic costs, with focus on the cost-utility ratio 1 year after surgery for thumb carpometacarpal osteoarthritis compared with that for continued nonsurgical management. METHODS: Patients with thumb carpometacarpal osteoarthritis indicated for resection arthroplasty were included in a prospective study. The quality of life (using European Quality of Life-5 Dimensions-5 Level), direct medical costs, and productivity losses were assessed up to 1 year after surgery. Baseline data at recruitment and costs sustained over 1 year before surgery served as a proxy for nonsurgical management. The total costs to gain 1 extra quality-adjusted life year and the incremental cost-effectiveness ratio were calculated from a health care system and a societal perspective. RESULTS: The mean European Quality of Life-5 Dimensions-5 Level value for 151 included patients improved significantly from 0.69 to 0.88 (after surgery). The productivity loss during the preoperative period was 47% for 49 working patients, which decreased to 26% 1 year after surgery. The total costs increased from US $20,451 in the preoperative year to US $24,374 in the postoperative year. This resulted in an incremental cost-effectiveness ratio of US $25,370 per quality-adjusted life year for surgery compared with that for simulated nonsurgical management. CONCLUSIONS: The calculated incremental cost-effectiveness ratio was clearly below the suggested Swiss threshold of US $92,000, indicating that thumb carpometacarpal surgery is a cost-effective intervention.

Global assessment of pollicization outcomes: an analysis in 27 patients.

Outcomes measurements after pollicization remains difficult due to the lack of a standardized assessment protocol. This study reports our experience of a global assessment of pollicized thumbs that includes a specific questionnaire for subjective evaluation, a detailed clinical assessment focused on functional outcomes incorporating function and usage of the pollicized thumb. Twenty-seven patients completed the questionnaire, and nine hands were clinically evaluated by a multidisciplinary team composed of hand surgeons and occupational therapists. Subjective evaluations revealed that 24 patients would recommend pollicization. Clinical evaluations revealed that only four out of nine patients properly integrated their pollicized thumb during bimanual activities; however, occupational therapy input allowed the children to compensate for the lack of strength and other difficulties. We propose the use of this global assessment package to analyse function and usage at various capacities, which can be useful for the surgeon, child and parents.Level of evidence: IV.

Cost Analysis and National Trends in the Treatment of Thumb Basal Arthritis: Comparing Ligament Reconstruction/Tendon Interposition and Trapeziectomy/Hematoma Distraction Arthroplasty.

BACKGROUND: Thumb basal arthritis (TBA) is a common form of arthritis characterized by wearing away of cartilage in the crarpometacarpal joint at the base of the thumb. The purpose of the study was to analyze cost trends of the 2 common surgical treatments options: ligament reconstruction/tendon interposition (LRTI) and trapeziectomy/hematoma distraction arthroplasty (THDA). METHODS: The Vizient Clinical Data/Resource Manager electronic database was reviewed for the 3 treatment procedures of TBA from January 1, 2016, to December 31, 2019. Cases were placed into 1 of 2 categories: LRTI or THDA. Total and direct costs were averaged and compared nationally and regionally. One-tailed t test and Pearson correlation analyses were performed (P < 0.05 and r > 0.9 or r < -0.9 was considered significant). RESULTS: A total of 28,887 total cases (26,405 LRTI, 2482 THDA) were analyzed. There was a 49% increase in number of surgical procedures to treat TBA between 2015 and 2018. Ligament reconstruction/tendon interposition (91%) had larger market share than THDA (9%). However, market share percentage of each procedure stayed the same over time. Trapeziectomy/hematoma distraction arthroplasty had lower average cost (US $4157) compared with that of LRTI (US $4446, P = 0.06) However, THDA had a significant positive trend in cost, increasing 14% in 4 years. In 2019, 30% of procedures performed were in the Midwestern United States, 27% Northeastern United States, 24% Southern United States, and 19% Western United States. CONCLUSIONS: Most patients with TBA seem to be treated with LRTI. The market share seems to be greatest for LRTI and lowest for THDA nationally and regionally. Although the average cost for THDA was less than that of LRTI, this difference was not significant.

Assessment of hand function using the functional dexterity test after opponensplasty in young children with Blauth type 2 hypoplastic thumb.

The functional dexterity test (FDT) is a timed pegboard test based on the manipulation of each peg and suitable for young children as it is both simple and quick to perform. We assessed the postoperative FDT values for children with Blauth type 2 hypoplastic thumbs after opponensplasty. We evaluated hand function using FDT for 12 hands of 11 patients with Blauth type 2 hypoplastic thumbs. Opponensplasty was performed in all hands following by Huber's procedure. All patients were evaluated from 6 to 12 months after surgery for hand function using three types of FDT scores: time in seconds to complete the test (FDT time), combined total time with penalty seconds added to the initial time (FDT total), and the number of pegs per second to complete the task as a percentage against normative values (FDT speed). We compared the postoperative FDT scores with those for Blauth type 1 or 2 hypoplastic thumb patients without surgical treatment. FDT time and FDT total for the patients postoperatively were both significantly shorter than those in the type 2 patients without surgical treatment. FDT speed was significantly higher than that for the patients without surgical treatment. There were no significant differences in the three FDT scores between the postoperative patients and the type 1 patients. There were several limitations including small sample size, large ranges of the data, and high number of variables. FDT reflected postopponensplasty improvement in hand dexterity in young children with Blauth type 2 hypoplastic thumb.

Nationwide Cost Variation for Thumb Replantation: A Population Study.

BACKGROUND: Health care reforms aimed at bundling payments attempt to contain costs. Uncovering variation in spending provides one strategy for decreasing expenditure. This study aims to investigate interhospital cost variation for thumb replantation. METHODS: A retrospective cross-sectional analysis of patients undergoing thumb replantation using data from the Healthcare Cost and Utilization Project National Inpatient Sample database from 2001 to 2011 was performed. Univariate and multivariable logistic regression models were used to investigate associations between patient-level and hospital-level characteristics and cost. RESULTS: A total of 778 patients were included in the study, with a mean cost for thumb replantation of $20,965. Thumb replantations performed at high-volume hospitals were significantly more expensive than those performed at low-volume hospitals (median cost, $20,395 versus $13,463; p < 0.001), with longer lengths of stay (5 days versus 4 days), despite having similar surgical complication rates (p = 0.07). Thumb replantations performed in the West were significantly more expensive than those performed in the South (median cost, $22,579 in the West versus $14,823 in the South; p < 0.001), with longer lengths of stay (5 days versus 4 days; p = 0.005) and similar surgical complications (p = 0.239). In multivariable logistic regression, hospital volume (p < 0.001), hospital region (p < 0.001), and increased length of stay (p < 0.001) were predictive of higher cost. CONCLUSIONS: High-volume hospitals and hospitals in the West are more expensive, with longer lengths of stay, despite having similar complications. Expedited discharge may be one avenue for decreasing expenditure without compromising care.

Clinical thresholds of symptoms for deciding on surgery for trapeziometacarpal osteoarthritis.

The severity of preoperative symptoms at which patients are likely to achieve a minimal important change and patient acceptable symptom state after surgery may help the decision to perform surgery for trapeziometacarpal osteoarthritis. The study objective was to define these thresholds for pain at rest and during activities as well as for the brief Michigan Hand Outcomes Questionnaire. One hundred and fifty-one patients were examined before surgery and 3, 6 and 12 months after surgery. The minimal important change after surgery was 1.9, 3.9 and 16 scores for pain at rest, pain during activities and the brief Michigan Hand Outcomes Questionnaire, respectively. The respective patient acceptable symptom state values were 1.5, 2.5 and 70 after surgery. Our results show that patients with baseline pain values between 3.5 and 5.5 at rest, between 6.5 and 7.5 during activities and a presurgery brief Michigan Hand Outcomes Questionnaire score of about 47, have the greatest chance of achieving a relevant symptom change and an acceptable symptom state. The information from this study may help surgeons in deciding the surgical indications and help patients in their expectation in symptom relief after surgery. Level of evidence: IV.

Comparison of Radiographic and Intraoperative Visual Assessment of Scaphotrapezoid Joint Arthritis in Patients With End-Stage Carpometacarpal Arthritis of the Thumb Base.

Background: The purpose of this investigation is to compare the radiographic and intraoperative assessment of scaphotrapezoid (ST) joint arthritis in patients with end-stage carpometacarpal (CMC) arthritis of the thumb base. We aim to define the incidence of ST arthritis in this population and determine whether radiographic features such as lunate morphology, dorsal intercalated segment instability (DISI), and scapholunate (SL) diastasis are associated with the incidence of ST arthritis. Methods: We retrospectively reviewed consecutive patients with end-stage CMC arthritis of the thumb treated operatively with trapeziectomy. Preoperative wrist radiographs were reviewed, and the presence of ST arthritis was determined using the Sodha classification. Lunate morphology, DISI, and SL diastasis were noted. Intraoperative grading of ST arthritis was assessed using a modified Brown classification. The specificity and sensitivity of radiographic assessment was compared with the gold standard of intraoperative direct visualization. Results: In total, 302 thumbs met inclusion criteria. End-stage ST joint arthritis determined by intraoperative visual inspection was noted in 31% of cases. No radiographic or demographic variables were found to be risk factors for ST arthritis. Plain radiographs were 47% sensitive and 94% specific in their ability to detect end-stage ST joint arthritis. Conclusions: We report a 31% incidence of end-stage ST joint arthritis in surgically treated patients with CMC arthritis based on visual inspection which is lower than previous literature. Wrist radiographs demonstrate a 47% sensitivity and 94% specificity in predicting end-stage ST joint arthritis. It is imperative to directly visualize the ST joint after trapeziectomy, as radiographs demonstrate poor sensitivity.

Inter- and Intrarater Reliability of the Thumb Grasp and Pinch Assessment for Children Following Index Pollicization for Congenital Thumb Hypoplasia.

PURPOSE: The Thumb Grasp and Pinch (T-GAP) assessment quantifies functional hand use in children with congenital thumb hypoplasia by categorizing grasp and thumb use patterns during assessment activities that encourage a variety of grasp and pinch styles. This study aims to demonstrate interrater and intrarater reliability results of the T-GAP. METHODS: A retrospective review was performed of children who had undergone index finger pollicization for congenital thumb hypoplasia and subsequent evaluation with videotaping of the T-GAP assessment. Following a training period, 4 occupational therapists scored 11 T-GAP videos on 2 separate occasions, separated by at least 2 weeks. Intraclass correlation coefficients (ICCs), standard error of measurements, minimum detectable change (MDC), and Pearson correlation coefficients were calculated. RESULTS: The T-GAP raw scores were 16 to 55, demonstrating a range of mild to severe hand grasp differences. The ICCs for the interrater reliability trials were 0.887 and 0.901. Intrarater ICCs were all above 0.88. The MDC for each trial was 8.1 and 6.7 points. Pearson correlation coefficients calculated for each rater and each pair of raters were above 0.8 in all cases. CONCLUSIONS: Interrater and intrarater reliability testing results for the T-GAP were excellent in all cases; this strongly suggests that results from T-GAP assessments are reliable. The high ICCs suggest that raters can classify and score children's hand function consistently. CLINICAL RELEVANCE: This study, in conjunction with previous work, suggests that the T-GAP may be an ideal approach to assessing the outcomes of pollicization and provide a means of ongoing assessment of children's grip and pinch function.

Description and Clinical Assessment of the Bone Block Tendon Interposition Technique for the Management of Thumb Carpometacarpal Joint Osteoarthritis.

BACKGROUND: Pellegrini's surgical technique is the most useful for thumb carpometacarpal joint osteoarthritis. The purpose of this paper is to describe the technique of a modified version using a bone block in the tunnel through which the flexor carpi radialis tendon is passed (BBTI). METHODS: Case series of patients diagnosed with osteoarthritis of the thumb carpometacarpal joint, in stage II or higher based on Eaton's classification, that were intervened using the BBTI technique for a 2-year period. Grip and pinch strength, range of motion, and 1-2 metacarpal angle were evaluated. Pain and function were measured using the visual analogue scale and the Disabilities of the Arm, Shoulder and Hand (DASH) scale. RESULTS: The study included 16 cases in 14 patients (11 women and 3 men), with an average age of 55.7 ± 7.1 years. Encouraging results were obtained, with an average DASH score of 24.3 ± 17.9 and a minimum VAS pain score. A total of 58% showed a grip strength of over 80% and the postoperative movement was equivalent to the contralateral limb. No cases of infection were reported, and only two minor complications were observed. CONCLUSIONS: The BBTI technique is a surgical option that incorporates an interference screw, offering good functional results for managing osteoarthritis of the thumb carpometacarpal joint, with a similar complication rate to that of the original technique.

Surgeon Preference, Influence, and Treatment of Thumb Carpometacarpal Arthritis.

BACKGROUND: The purpose of this study was to evaluate current surgical practice patterns, the factors that influence these patterns, and overall trends in the treatment of thumb carpometacarpal osteoarthritis. METHODS: An online survey containing 14 questions was sent to all active members of the American Society for Surgery of the Hand. Information on demographics and treatments was collected. Results were anonymously uploaded to an online spreadsheet. RESULTS: A total of 823 responses were recorded. Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) using whole flexor carpi radialis was the most popular technique at 37.44%. In all, 26.38% of surgeons with fewer than 5 years of experience utilize trapeziectomy with suture suspension (bone anchor based or tendon based); 55.76% choose a particular procedure because of "Personal Clinical Experience" over "Current Evidence" and "Training." In addition, 24.17% of surgeons who have been practicing for longer than 5 years have changed procedures in the last 5 years. In the United States, 97.2% of hand surgeons prescribe either oxycodone or hydrocodone postoperatively compared with just 23.75% of international hand surgeons. CONCLUSIONS: The results show that trapeziectomy with LRTI remains the most popular treatment of choice. The use of trapeziectomy with suture suspension is on the rise, particularly in younger surgeons. International hand surgeons rely more on current evidence, utilize less postoperative therapy and opioid medications, and change procedures more often than US hand surgeons.

Setting the Goals in the Management of Mutilated Injuries of the Hand-Impressions Based on the Ganga Hospital Experience.

Mutilated injuries need to be treated aggressively and appropriately to avoid amputation or severe disability in the individual. Assessment of the management of these injuries on a global level reveals that there is a gap between the need and availability of the skilled manpower to manage these injuries. There is also a gap in the utilization of the available services. These gaps need to be covered or narrowed as far as possible. Although some measures need policy changes and improvement of health care delivery infrastructure, simpler measures taken at the final health care delivery level can significantly improve the final outcome.

Medicare Spending and Evidence-Based Approach in Surgical Treatment of Thumb Carpometacarpal Joint Arthritis: 2001 to 2010.

BACKGROUND: Despite equivalent outcomes among surgical treatments of thumb carpometacarpal arthritis, little is known about the variation in spending. Because of its complexities, the authors hypothesized that trapeziectomy with ligament reconstruction and tendon interposition incurs the greatest cost to Medicare compared with other surgical procedures. METHODS: Using a random 5 percent sample of Medicare beneficiaries diagnosed with thumb carpometacarpal joint arthritis, the authors examined total and out-of-pocket spending for 3530 patients who underwent a surgical treatment between 2001 and 2010. The authors used generalized linear regression models, controlling for patient characteristics and place of surgery, to examine variations in spending. RESULTS: Eighty-nine percent of patients who underwent surgery received trapeziectomy with ligament reconstruction and tendon interposition, with total and out-of-pocket spending of $2576 (95 percent CI, $2333 to $2843; p < 0.001) and $436 (95 percent CI, $429 to $531; p < 0.001), respectively. Simple complete trapeziectomy was the least expensive procedure, performed in 5 percent of patients, with total and out-of-pocket spending of $1268 (95 percent CI, $1089 to $1476; p < 0.001) and $236 (95 percent CI, $180 to $258; p < 0.001), respectively. Because of increasingly higher facility costs, performing the same procedure in a hospital outpatient setting compared with an ambulatory center would increase Medicare spending by more than two-fold (p < 0.001). CONCLUSIONS: With a consistent rise in health care spending, adherence to an evidence-based approach in medicine is more important than ever. Most surgeons continue to perform trapeziectomy with ligament reconstruction and tendon interposition, the most expensive surgical option. Medicare could potentially save $7.4 million annually if simple complete trapeziectomy was the procedure of choice.

Healthcare costs and loss of productivity in patients with trapeziometacarpal osteoarthritis.

The objective of this study was to analyse healthcare and productivity costs in patients with trapeziometacarpal osteoarthritis. We included 161 patients who received surgery or steroid injection and calculated their healthcare costs in Euro (€) over 1 year. Patients filled out the Work Productivity and Activity Impairment Questionnaire to assess loss of productivity at baseline, and after 3, and 12 months. In the surgical group, loss of productivity among employed patients first increased and then decreased (50%, 64%, and 25% at 0, 3, and 12 months). Productivity was more stable over time in the injection group (52%, 38%, and 48%). In the surgical group, estimated total annual healthcare and productivity costs were €5770 and €5548, respectively. In the injection group, healthcare and productivity costs were €348 and €3503. These findings highlight the need for assessing productivity costs to get a comprehensive view of the costs associated with a treatment.Level of Evidence III.

Nail Fusion Plasty: Nail Cosmetic Results and Assessment Criteria of Nail Reconstruction.

PURPOSE: This study aimed to develop a scoring system for evaluating the nail appearance after nail fusion plasty of the duplicated thumb, and to investigate the operation indication of the combination procedure and its effect on the postoperative nail appearance. METHODS: The nail fusion plasty technique was carried out in 20 patients with congenital thumb duplication. The patients were followed up to observe the appearance of nail, and the results were assessed by our nail appearance evaluation criteria. RESULTS: Twenty patients were followed up for 18 to 92 months (48 months on average). According to our criteria, we achieved excellent results in 12 cases, good in 6 cases, fair in 1 case, and poor in 1 case. CONCLUSIONS: The combination procedure is recommended when the size of the thumb is less than 80% of the size of the normal side or the width of the nail is less than 80% of that of the normal side. Satisfactory results can be obtained by careful operation. The newly devised scoring system assesses the nail appearance in a very comprehensive manner.
