Current national hand surgery registries worldwide

The Canadian Prospective Pragmatic Perilunate Outcomes (C3PO) trial; a protocol

BACKGROUND

Perilunate spectrum injuries (PSI) are uncommon, but high-energy injuries that result in significant functional implications for patients. The existing literature on PSI is limited to small case-series and there are no evidence-based guidelines for management.

METHODS

This manuscript outlines a protocol for a three-armed, national, multi-centre study, which includes a patient injury registry for PSI, as well as associated retrospective and prospective arms. The primary objective is to establish a national injury registry for patients who present with PSI. The secondary objectives are to examine the long-term clinical and radiographic outcomes of PSI, evaluate progression of these outcomes over time, and to examine the impact of specific operative and injury related factors on outcomes.

DISCUSSION

This paper describes the protocol for a three-armed, multi-centre study of PSI. It outlines the rationale for the study as well as the relevant methodological details. An injury registry involving multiple centres is valuable given this is an uncommon injury with many potential variables affecting outcomes. Registry-based retrospective and prospective studies will benefit from the large clinical database provided by the registry and could be used to guide evidence-based treatment guidelines which are currently lacking in the literature.

Episode-Based Bundled Payments in Hand Surgery: An Affordable Solution to Overwhelming Health Care Costs

The purpose of this review is to examine the literature regarding episode-based bundled payment models for hand surgery. Health care and productivity costs associated with the surgical management of hand and wrist pathologies represent a substantial burden on the United States health care system. Traditional fee-for-service models fail to incentivize interdisciplinary collaboration and optimization of resources. More recently, the concept of episode-based bundled payments has evolved as a potential solution to rising health care costs by encouraging care coordination, streamlining billing processes, and linking reimbursement to quality metrics and patient outcomes as opposed to the volume of services rendered. Although episode-based bundled payments have demonstrated the potential to reduce health care costs in various medical specialties, their feasibility in hand surgery remains relatively unexplored. The transition to episode-based bundled payments in hand surgery hinges on the ability to incentivize physicians to work cohesively with other members of the care team to reduce low-value preoperative testing, optimize patients preoperatively, and establish treatment guidelines, especially for patients undergoing high-volume, low-complexity procedures. By fostering collaboration among stakeholders, leveraging data-driven insights, and prioritizing patient-centered care, episode-based bundled payments have the potential to enhance the value and efficiency of hand surgery services while improving patient outcomes. The current literature regarding episode-based bundled payments in hand surgery highlights various avenues for cost savings, including alternative sites of service, surgical approaches, use of anesthesia, and the elimination of low-value tests, and demonstrates that there is sufficient evidence to proceed to a trial phase for episode-based bundled payments in hand surgery.

Registration of finger implants in the Dutch arthroplasty registry (LROI)

Finger arthroplasty is commonly used to treat pain in the finger joints due to osteoarthritis or rheumatoid arthritis. Despite the procedure having existed for a relatively long time, it is still unknown which characteristics influence implant survival. The Dutch Arthroplasty Registry (LROI) is one of the 4 registries worldwide registering finger arthroplasties. This study aimed to investigate impact factors for implant survival regarding finger joint arthroplasty and assess registration completeness using the national healthcare claims database to compare. A total of 951 primary arthroplasties and 84 revision arthroplasties of the finger joints were registered. A higher likelihood of primary and revision surgery was found in female patients. The third and fourth proximal interphalangeal (PIP) joints were the most frequently operated in primary surgery; however, the metacarpophalangeal (MCP) joints were the most frequently revised joints. Silicone implants were used in most cases and evenly throughout all digits. Suboptimal registration completeness was shown for plastic surgeons with just 35.5%-37.4% of all surgeries registered. Although orthopedic surgeons do not perform most surgeries on the hand, they registered 76.5%-78.2% of surgeries. No statistical analyses were justified, considering the low completeness and limited follow-up. Female gender and PIP joint disease are possible risk factors for primary arthroplasty. MCP arthroplasties showed higher revision rates. However, participation rates and, therefore, data completeness were not optimal. To optimize participation, improving ease of registration should be explored. Furthermore, we urge readers who deal with joint implants to register their surgeries in the LROI database because only optimal registration completeness leads to high-quality data.

Increasing Use of Total Wrist Arthroplasty-An Australian National Joint Registry Report

Background and Purpose  There is limited literature reporting the long-term results and outcomes of total wrist arthroplasty (TWA). The aim of this study was to describe the incidence, usage, and survival of wrist arthroplasty using data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR). Methods  Data included all primary TWA procedures from 2006 to 2021. The primary outcome assessed was revision surgery. Utilization of TWA, etiology leading to TWA, patient demographics, and surgical factors were also assessed. Results  There were 439 primary TWA procedures performed across the 16-year reporting period. Four prostheses (Motec, Universal 2, Freedom, and ReMotion) have been used, with a recent increased usage toward the Motec, which accounted for 97.4% of prostheses implanted in 2021. There has also been an increase in the number of surgeons performing TWA over time. The most common underlying etiology was osteoarthritis (72.7%), followed by rheumatoid arthritis (15.9%). Implantation for inflammatory arthropathy remained relatively constant across time; however, TWA has been utilized with increasing frequency for the treatment of osteoarthritis and other indications more recently. The cumulative percent revision at 10 years was 18.3%. Loosening accounted for 25.6% of all revisions, followed by osteolysis (12.8%), pain (12.8%), and instability (7.7%). Attempted conversion to an arthrodesis occurred in 10.3% of all revisions. Conclusion  There has been an increase in both the volume of TWA performed and the number of surgeons undertaking this procedure in Australia over the past 16 years. The Motec system has become the prosthesis of choice. Medium-term revision rates are inferior when compared with Australian data for hip, knee, and shoulder arthroplasty.

Thumb Arthroplasty as Reliable Long-term Solution for Trapeziometacarpal Osteoarthritis: A Minimum of 15 Years of Follow-up

BACKGROUND

In patients with symptomatic trapeziometacarpal (TMC) joint arthritis resistant to conservative treatment, surgical treatment can be advised. One of the many surgical treatment options is TMC arthroplasty. The Arpe prosthesis is one example of these TMC arthroplasties.

METHODS

This retrospective study evaluated patients who underwent TMC arthroplasty with the Arpe prosthesis after a minimum of 15 years of follow-up. Clinical, radiologic, and qualitative outcomes were assessed for 43 Arpe arthroplasties in 41 patients, of whom 2 had bilateral arthroplasties. The female to male ratio was 39:4. The mean follow-up time was 197 months (range = 180-225).

RESULTS

The cumulative survival rate after a mean of 16.5 years was 84%. Seven failures (16%) were registered, of which 5 during the first 3 years after primary surgery. All patients were successfully converted to a trapeziectomy. Quick Disabilities of the Arm, Shoulder and Hand score improved with 44.9 points and visual analogue pain score with 97% and 91% at rest and during exercise, respectively.

CONCLUSIONS

This series demonstrates that thumb arthroplasty is a reliable long-term solution for thumb base arthritis, with significant pain reduction and functional improvement, even after 15 years of follow-up.

Biomechanics of the proximal interphalangeal joint after total joint replacement

Introduction Small joints arthroplasty of the hand including the proximal interphalangeal joint (PIPJ) is associated with the need to create anatomically adapted structures using optimal materials. Introduction of a new medical device requires comprehensive preclinical testing.

The objective was to determine a range of loads allowed for the proximal interphalangeal joint after arthroplasty through analyzing the biomechanics to prevent critical conditions and complications.

Methods A full-ceramic non-constrained anatomically adapted proximal interphalangeal joint implant was developed between 2016 and 2021 using an integrated approach with preclinical trials and a clinical study of 42 patients (25 males, 17 females) with PIPJ arthritis. A digital endoprosthesis was created with 3D-modelling. Critical conditions for the digital model imitating typical joint movements were explored with the use of finite element method and the findings to be employed in clinical practice.

Results A stable biomechanical construct was intact with loads of 5 kilograms and a motion ranging from 0 to 60 degrees, with loads of 20 kilograms and a motion ranging between 0 and 30 degrees. Cortical bone could sustain loads up to 20 kilograms with a motion ranging between 0 and 60 degrees. Discussion Load capacity of the implant was explored considering the strength of bone tissue and zirconium ceramics as a material. The study set a vector for the development of the optimal mode of motor activity early after surgery and indicated the optimal range of motion to be applied after PIPJ arthroplasty.

Conclusion The load up to 5 kg was optimal for the patient to be applied early after surgery with the range of flexion measuring less that 90°. The patient could use a load of 5 to 20 kg with flexion in the proximal interphalangeal joint measuring less than 30°. Endoprosthetic components were likely to get dislocated with a load of 20 kg and flexion angle of greater than 30°. Periprosthetic fracture could occur with flexion angle of greater than 60°.

Patient Experiences after Open Trigger Finger Release in Patients with Type 1 and Type 2 Diabetes-A Retrospective Study Using Patient-reported Outcome Measures

Trigger finger is overrepresented among patients with diabetes mellitus (DM). Whether DM affects the outcome after open trigger finger release (OTFR) in patients with DM is not known. Our aim was thus to explore outcomes after OTFR in patients with type 1 (T1D) and type 2 DM (T2D).

Methods

Data included patient-reported outcome measures (PROMs) from all OTFRs performed between 2010 and 2020 registered in the Swedish national registry for hand surgery in individuals over 18 years cross-linked with the Swedish National Diabetes Register (NDR). PROMs included QuickDASH and HQ8, a questionnaire designed for national registry for hand surgery, preoperative and at 3 and 12 months postoperative. HQ8 included pain on load, pain on motion without load, and stiffness. Outcome was calculated using linear-mixed models and presented as means adjusted for age and stratified by sex.

Results

In total, 6242 OTFRs were included, whereof 496 had T1D (332, 67% women) and 869 had T2D (451, 52% women). Women with T1D reported more symptoms of stiffness (P < 0.001), and women with T2D reported more pain on load (P < 0.05), motion without load (P < 0.01), and worse overall result at 3 months. At 12 months, however, no differences were found in any of the HQ-8 PROMs among men or women. Women with T2D had slightly higher QuickDASH scores at 3 and 12 months.

Conclusion

Patients with T1D and T2D can expect the same results after OTFR as individuals without DM, although the improvement might take longer especially among women with T2D.

Value-Based Health Care in Hand Surgery: Where Are We & Where Do We Go From Here?

Health care delivery is broken. The cost of care continues to skyrocket and the outcomes most important to patients are often a mystery. Further, care is often delivered via a fee-for-service model where surgeons are rewarded for the quantity, not the quality, of services provided. Such a health care delivery system is not sustainable and does not incentivize stakeholders to focus on the most important element of the health care delivery "puzzle": the patient. Fortunately, we are in the midst of transforming our health care delivery system, with a focus on optimizing the value of care delivery (ie, health outcomes achieved per dollar spent across a full care cycle). In hand surgery, progress has been made as part of this health system evolution. However, there remains much to accomplish. In this article, the authors review the 6 components of a strategic agenda for moving to a high-value health care delivery system for hand surgery, focusing on where we are today and where we need to go from here.
