Hemiarthroplasty for Complex Distal Radius Fractures in Elderly Patients

Hemiarthroplasty for irreparable distal radius fractures in the elderly: A comprehensive review

BACKGROUND

Elderly patients maintaining functional independence can now be candidates for primary wrist hemiarthroplasty to manage acute irreparable distal radius fractures (DRFs). However, further investigation with long-term follow-up is required to validate these initial findings.

AIM

To review the literature on the outcomes of distal radius hemiarthroplasty with available implants to assess its viability as a treatment option.

METHODS

A comprehensive review of the literature was conducted using electronic databases, including PubMed, Medline, and Scopus. The search terms employed were "distal radius fracture" , "hemiarthroplasty" , "wrist arthroplasty" , and related terminology. The search was restricted to articles published in English from 1980 until June 2023. Inclusion criteria encompassed cases or case series of DRF treated with hemiarthroplasty, providing clinical or radiographic outcomes, and published in peer-reviewed journals.

RESULTS

A total of 2508 articles from PubMed and 883 from Scopus were identified initially. Following screening and removal of duplicates, 13 articles met the inclusion criteria. These articles, predominantly clinical retrospective studies, provided insights into hemiarthroplasty outcomes, including functional improvements and complications. Hemiarthroplasty was a treatment option for complex DRF, particularly those cases with severe comminution, intraarticular involvement, or severe osteoporosis. Functional outcomes demonstrated improvements in pain relief, wrist mobility, and grip strength, with variability across studies. Complications included implant loosening, infection, nerve injury, and stiffness, with varying incidence rates influenced by surgical techniques and implant choice. Long-term outcomes were inadequately documented, warranting further research.

CONCLUSION

Hemiarthroplasty is a promising treatment for irreparable DRF in the elderly. Long-term outcomes and complications require further study.

Wrist Hemiarthroplasty of Irreparable Distal Radius Fracture under Wide-Awake Local Anesthetic and No Tourniquet

Distal radius fractures (DRF) are common in elderly patients and the incidence continues to increase with the aging of the population. For irreparable fractures in the elderly, treatment with a reduction cast leads to unreliable results and frequent complications when treated with an anterior plate. Recent studies on hemiarthroplasty for elderly complex wrist fractures have resulted in good clinical and radiologic outcomes, as well as high satisfaction rates. Incorporating wide-awake local anesthesia and no tourniquet (WALANT) in surgical management is beneficial in DRF plating. This technique has not been performed in wrist hemiarthroplasty for an irreparable fracture in an elderly osteoporotic woman. This article describes the WALANT procedure for wrist hemiarthroplasty in a single case, with a detailed description of the technique.

Wrist Hemiarthroplasty for Complex Intraarticular Distal Radius Fracture in a Patient with Manifest Osteoporosis

Distal radius fracture (DRF) is one of the most common fractures of the elderly. The higher the degree of joint surface destruction, and the more adverse factors are involved, the more challenging proper treatment becomes. In this regard, osteoporosis as underlying systemic disease, chondropathy or degeneration of adjacent wrist bones as well as incompliance significantly impair the success of the chosen primary therapy. Wrist hemiarthroplasty has already been reported as primary or secondary procedure for DRFs. In this case report, we present a patient with a severely comminuted DRF including posttraumatic degeneration of the lunate as well as manifest osteoporosis. Wrist hemiarthroplasty using the ReMotion radius component in combination with proximal row carpectomy was performed as secondary surgery. This procedure proved to be a viable treatment option in terms of achieving low pain levels, high range of motion values and stable osteointegration over a course of 6.5 follow-up years.

Lessons learned with the Cobra prosthesis in elderly patients with complex distal radius fractures-a retrospective follow-up study

INTRODUCTION

Recently, the Cobra prostheses were introduced in the treatment of distal radius fractures (DRF) of elderly patients. Fracture prostheses provide an alternative treatment option for complex fractures where conservative therapy seems not acceptable and osteosynthesis seems not possible. Data reporting the feasibility of the Cobra prosthesis are sparse. Therefore, this retrospective follow-up study investigated the clinical and radiological mid-term outcome of the Cobra implant in complex DRFs of elderly patients.

MATERIALS AND METHODS

Thirteen patients (mean age 73.5 years, range 65-87 years) were retrospectively evaluated with at least a 1-year follow-up after surgery. Objective and subjective clinical parameters as well as the radiological outcome and complications were analyzed.

RESULTS

The mean follow-up period was 31.2 months. Seven cases required a cemented prosthesis. The mean relative range-of-motion compared to the healthy side was 72.3% and 51.8% for extension and flexion, respectively, and 87.9% and 85.7% for pronation and supination, respectively. The mean grip strength was 78.3% compared to the non-operated side. Eight patients were very satisfied, five patients were partly satisfied with the result. The DASH, PRWE, MHQ and Lyon-Scores averaged 39.1, 36.2, 64.9 and 63.3 points, respectively. The mean VAS-Score for pain was 1.1 at rest and 3.2 during activities. Perioperative complications included one dissection of the extensor pollicis longus tendon, one heterotopic ossification, one radiocarpal dislocation and two cases of an ulnar impaction syndrome due to implant subsidence.

CONCLUSION

The prosthetic treatment of complex DRFs in elderly patients with the Cobra implant led to clinically and radiologically satisfactory mid-term results. The Cobra prosthesis still does not represent a gold standard but can be regarded as a feasible salvage option for complex DRFs when osteosyntheses may not be possible and non-operative treatment will lead to further functional restrictions and wrist pain during performing activities of daily life in high functional demand patients.

Isoelastic resurfacing prosthesis for distal radius fractures: Outcomes in 24 cases with at least 2 years' follow-up

BACKGROUND

Unicompartmental resurfacing prostheses have been reported to be useful for treating comminuted fractures involving the distal radial joint surface in elderly patients with osteoporosis. However, the data on this method remain scarce and further evaluations are needed. The objective of this study was to evaluate the clinical and radiological outcomes after unicompartmental resurfacing prosthesis implantation in patients with distal radius fractures and at least 2 years' follow-up.

HYPOTHESIS

Outcomes with Prosthelast® are as good in the mid-term as in the short term.

MATERIALS AND METHODS

We studied 24 patients with type C fractures in the AO classification. The Prosthelast® prosthesis was implanted in each. Mean age was 78 years (60 to 91). There were 22 females. Three of the fractures were open. The patients were evaluated clinically using a visual analogue scale (VAS) for pain, ranges of motion at the wrist, and grip strength. In addition, functional scores were determined, and radiographs obtained.

RESULTS

Mean follow-up was 55.2 months (24-97). Mean tourniquet time was 61.9minutes (37-126). Mean motion ranges were 39° in flexion, 49° in extension, 74° in pronation, and 68° in supination. The mean VAS pain score was 2.1 (0-7). The mean Quick DASH was 39.8 (9.09-77), the mean PRWE was 42.7 (5-95), and mean grip strength was 38 (25-150). Painful motion limitation of the elbow was noted in a patient treated with total elbow prosthesis. Complex regional pain syndrome developed in 6 patients, and 5 patients required revision surgery. Asymptomatic perforation of the radial head occurred in 8 patients. No cases of peri-prosthetic osteolysis or osteoarthritis were noted. The prosthesis impinged on the lunate bone in 2 patients and on the scaphoid bone in one patient. Mean ulnar variance was +0.17mm (-1 to 7.5). Bone remodelling about the prosthesis was noted in all the patients, but 2.

DISCUSSION

Our data obtained after a mean follow-up of 55 months indicate that resurfacing prostheses have a role to play in the treatment of comminuted articular fractures in patients with osteoporosis. A long-term study is needed to further evaluate these results.

LEVEL OF EVIDENCE

IV; therapeutic.

Emerging Technologies in Distal Radius Fracture Fixation

PURPOSE OF REVIEW

To provide an overview of emerging fixation constructs and materials used in the operative management of distal radius fractures.

RECENT FINDINGS

The indications, advantages, and disadvantages of relatively new implants and devices used to treat distal radius fractures are discussed. These include the intramedullary nail, intramedullary cage, radiolucent volar locking plate, distal radius hemiarthroplasty, and bone graft substitutes. The spectrum of distal radius fracture patterns may make it impossible to depend on a single device for fixation, and surgeons managing distal radius fractures should be adept at using various surgical approaches, techniques, and hardware systems. Additional studies demonstrating the cost-effectiveness, biomechanical properties, and clinical outcomes will be useful in determining the utility of the described techniques.

Results of wrist hemiarthroplasty for comminuted distal radius fractures in independent elderly people: A retrospective study on eleven patients

The comminuted distal radius fractures among elderly people are usually linked to osteoporosis, and repairing them in this context is a therapeutical challenge. Several teams have reported good results of radius resurfacing. The goal of our study was to evaluate the usability of the wrist in a new series of patients after surgery. We performed a monocentric retrospective study on the data of the medical files. All the included patients were older than 65 years and received a wrist hemiarthroplasty according to the criteria that have been established by the in charge medical team. Eleven patients have been included, their average age was 80.4 years old, and the average follow-up was 18.3  months. The average QuickDASH Score was 59 (27-95). The Visual Analogue Scale for pain was in average 3.8/10 and the average mobility was: flexion 36° (12-50), extension 27° (12-50), radial deviation 15° (12-15), ulnar deviation 26° (12-40), pronation-supination range of motion 164° (150-170). The average measured strength was 44% (16-72%) of the strength of the unaffected hand. Our results are rather modest, probably because of insufficient follow-up and very severe fractures. Furthermore, the implant that has been used does not take into account the distal radioulnar joint. Another bound of this treatment is the complexity of surgical revision in case of bad result. So far, hemiarthroplasty cannot be considered as the standard treatment for complex fractures of the distal radius.

Hemi-arthroplasty for distal radius fracture in the independent elderly

INTRODUCTION

The authors report their experience with hemi-arthroplasty in irreparable fresh distal radius fracture in independent elderly patients as first-line treatment (12 fractures in 11 women; mean age, 74 years) or in second line after clinically disabling primary failure (4 fractures in 4 women; mean age, 78 years).

RESULTS

In the 12 primary surgeries, at a mean 32 months' follow-up, there were no complications requiring implant ablation; mean pain score was 1/10, flexion-extension 62°, Lyon Wrist score 75%, and Patient-Related Wrist Evaluation (PRWE) 22 points. In 2 of the 4 secondary surgeries, at a mean 24 months' follow-up, there were no complications requiring implant ablation; mean pain score was 2.5/10, flexion-extension 62°, Lyon Wrist score 58%, and PRWE 50 points: i.e., slightly poorer results than in primary surgery.

CONCLUSION

Salvage of complex fracture in independent elderly patients by hemi-arthroplasty, whether primary or secondary to failure, seems to be a considerable progress, to be confirmed in larger series.

[What is the role of primary or secondary hemiarthroplasty for distal radius fractures in independent elderly patients?]

The authors report their experience with wrist hemiarthroplasty for acute irreparable distal radius fractures in independent elderly patients (12 women, mean age 76years) and following failed initial treatment in the same population (5 women, mean age 75years). The first 11 cases have a mean follow-up of 30months. No complications requiring implant removal were reported. At follow-up, the mean VAS for pain was 1/10, the mean flexion-extension arc was 60°, the Lyon Wrist score was 73 % and the PRWE (Patient-Related Wrist Evaluation) was 22 points. The five patients who had secondary procedures and were reviewed at mean of 16months' follow-up did not require implant removal but there was one complete forearm rotational ankylosis with ossification. At follow-up, the mean VAS for pain was 3/10, the mean flexion-extension arc was 56°, the Lyon Wrist score was 65 % and the PRWE was 45 points. The authors believe that hemiarthroplasty is a useful salvage procedure for irreparable wrist fractures in the emergency room and after failed initial treatment in active elderly patients.
