Cost-Effectiveness of Treatments after Closed Extraarticular Distal Radius Fractures in Older Adults from the WRIST Clinical Trial

The Role of External Fixation in the Treatment of Distal Radius Fractures

There are numerous internal fixation (IF) options available for distal radius fractures (DRFs). The choice of fixation method depends on factors such as fracture morphology, soft tissue integrity, the patient's clinical status, and the surgeon's training. While volar plate fixation has become the primary approach for addressing these fractures, alternative IF methods like K-wire fixation, fragment-specific fixation, and dorsal bridge plating continue to be effective. Despite the versatility of IF, there are certain clinical situations where prompt and conclusive management through open reduction and internal fixation (ORIF) is not suitable. These instances include the treatment of polytraumatized patients, individuals with compromised soft tissues, or those medically unstable to tolerate lengthy anesthesia. In such cases, proficiency in closed reduction and external fixation (EF) proves invaluable. Being able to identify these clinical scenarios and comprehend the efficacy and safety of EF in addressing DRFs is valuable for any surgeon handling such injuries.

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).

Current Management and Volar Locking Plate Fixation with Bone Cement Augmentation for Elderly Distal Radius Fractures-An Updated Narrative Review

Distal radius fractures (DRFs) are the most common among all kinds of fractures with an increase in incidence due to the rapidly expanded size of the elderly population in the past decades. Both non-surgical and surgical treatments can be applied for this common injury. Nowadays, more and more elderly patients with DRFs undergo surgical treatments to restore pre-injury activity levels faster. However, optimal treatment for geriatric DRFs is still debated, and careful evaluation and selection of patients are warranted considering clinical and functional outcomes, and complications following surgical treatments. Furthermore, osteoporosis is a predominant factor in elderly DRFs mostly deriving from a low-energy trauma, so many treatment modalities are developed to enhance better bone healing. Among various options for bone augmentation, bone cement is one of the most widely used measures. Bone cement such as calcium phosphate theoretically improves fracture stability and healing, but whether the elderly patients with DRFs can significantly benefit from surgical fixation with bone cement augmentation (BCA) remains controversial. Hence, in the present review, the latest literature regarding current concepts of management and evidence about volar locking plate fixation (VLPF) with BCA for elderly DRFs was searched in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Web of Science; out of >1000 articles, full texts of 48 and 6 articles were then examined and analyzed separately for management and VLPF with BCA for elderly DRFs. We aim to provide the readers with updates concerning the above issues.

A Cost-Effectiveness Analysis of the Various Treatment Options for Distal Radius Fractures

Purpose

To conduct a cost-effectiveness study of nonsurgical and surgical treatment options for distal radius fractures using distinct posttreatment outcome patterns.

Methods

We created a decision tree to model the following treatment modalities for distal radius fractures: nonsurgical management, external fixation, percutaneous pinning, and plate fixation. Each node of the model was associated with specific costs in dollars, a utility adjustment (quality-adjusted life year [QALY]), and a percent likelihood. The nodes of the decision tree included uneventful healing, eventful healing and no further intervention, carpal tunnel syndrome, trigger finger, and tendon rupture as well as associated treatments for each event. The percent probabilities of each transition state, QALY values, and costs of intervention were gleaned from a systematic review. Rollback and incremental cost-effectiveness ratio analyses were conducted to identify optimal treatment strategies. Threshold values of $50,000/QALY and $100,000/QALY were used to distinguish the modalities in the incremental cost-effectiveness ratio analysis.

Results

Both the rollback analysis and the incremental cost-effectiveness ratio analysis revealed nonsurgical management as the predominant strategy when compared with the other operative modalities. Nonsurgical management dominated external fixation and plate fixation, although it was comparable with percutaneous fixation, yielding a $2,242 lesser cost and 0.017 lesser effectiveness.

Conclusions

The cost effectiveness of nonsurgical management is driven by its decreased cost to the health care system. Plate and external fixation have been shown to be both more expensive and less effective than other proposed treatments. Percutaneous pinning has demonstrated more favorable effectiveness in the literature than plate and external fixation and, thus, may be more cost effective in certain circumstances. Future studies may find value in investigating further clinical aspects of distal radius fractures and their association with nonsurgical management versus that with plate fixation.

Surgical plating versus closed reduction for fractures in the distal radius in older patients: a cost-effectiveness analysis from the hospital perspective

BACKGROUND

Given the cost differential between surgical and non-surgical management of distal radius fractures, we aimed to evaluate the cost-effectiveness of surgical compared with non-surgical treatment of distal radius fractures in a cohort of older patients.

METHODS

This evaluation was conducted alongside the combined randomized and observational study of surgery for fractures of the distal radius in the elderly (CROSSFIRE) trial (ACTRN 12616000969460) which compared surgical (open reduction and internal fixation using volar-locking plate (VLP) fixation) and non-surgical (closed fracture reduction and cast immobilization (CR)) treatment for displaced distal radius fractures in patients ≥60 years. Cost-effectiveness was assessed from the perspective of the public hospital funder. Hospital records from a sub-sample of participants were used to estimate costs. Outcomes were patient-reported wrist pain and function questionnaire (PRWE) scores and quality adjusted life years (QALYs) calculated using the EuroQoL five-dimension five-level tool (EQ-5D-5L).

RESULTS

From 166 participants (81 surgical, 85 non-surgical), costs were obtained for 56 (29 surgical, 27 non-surgical). The mean costs for VLP fixation were Australian dollars (AUD) 6668 (95% CI $4857 to $8479) compared to AUD 3343 (95% CI $1304 to $5381) for CR. The incremental cost-effectiveness ratios (ICER) to achieve a 1-point improvement in the PRWE were AUD 375, AUD 1736 and AUD 1126 at 3, 12 and 24 months for VLP compared with CR. At 12 months, the cost effectiveness was dominated by CR (lower cost and better QoL) whereas at 24 months, the incremental cost per QALY gained by VLP was AUD 1 946 127.

CONCLUSION

In the treatment of distal radius fractures in patients ≥60 years, VLP fixation was not cost-effective compared with CR from the perspective of hospital funders.

Role of Pronator Quadratus Repair in Volar Locking Plate Treatment of Distal Radius Fractures

Distal radius fractures are the most common type of upper extremity fractures, and their incidence is increasing. There has been a rise in the surgical treatment of distal radius fractures, primarily with volar locking plate fixation. Although this procedure is commonly done among orthopaedic surgeons, the role of pronator quadratus repair after fixation remains controversial. The pronator quadratus serves as a secondary forearm pronator and a dynamic stabilizer of the distal radioulnar joint. Aside from a functional role, repair of the pronator quadratus has been proposed to serve as a biologic barrier between the volar locking plate and the flexor tendons to minimize tendon irritation. In this narrative review, we discuss the current treatment trends, the surgical approach for volar locking plate treatment of distal radius fractures, and the anatomy and function of the pronator quadratus. We discuss the case for and against the repair of the pronator quadratus, both for function and prevention of flexor tendon irritation and rupture. The preponderance of high-level evidence demonstrates no benefit to pronator quadratus repair for pain relief or function. The current evidence does not conclusively support or refute pronator quadratus repair as a biologic barrier from the flexor tendons.

Surgical treatment is not cost-effective compared to nonoperative treatment for displaced distal radius fractures in patients 65 years and over

Aims

The purpose was to compare operative treatment with a volar plate and nonoperative treatment of displaced distal radius fractures in patients aged 65 years and over in a cost-effectiveness analysis.

Methods

A cost-utility analysis was performed alongside a randomized controlled trial. A total of 50 patients were randomized to each group. We prospectively collected data on resource use during the first year post-fracture, and estimated costs of initial treatment, further operations, physiotherapy, home nursing, and production loss. Health-related quality of life was based on the Euro-QoL five-dimension, five-level (EQ-5D-5L) utility index, and quality-adjusted life-years (QALYs) were calculated.

Results

The mean QALYs were 0.05 higher in the operative group during the first 12 months (p = 0.260). The healthcare provider costs were €1,533 higher per patient in the operative group: €3,589 in the operative group and 2,056 in the nonoperative group. With a suggested willingness to pay of €27,500 per QALY there was a 45% chance for operative treatment to be cost-effective. For both groups, the main costs were related to the primary treatment. The primary surgery was the main driver of the difference between the groups. The costs related to loss of production were high in both groups, despite high rates of retirement. Retirement rate was unevenly distributed between the groups and was not included in the analysis.

Conclusion

Surgical treatment was not cost-effective in patients aged 65 years and older compared to nonoperative treatment of displaced distal radius fractures in a healthcare perspective. Costs related to loss of production might change this in the future if the retirement age increases.
