Salvage of the Failed Total Wrist Arthroplasty: A Systematic Review

Patient reported and functional outcome measures after surgical salvage procedures for posttraumatic radiocarpal osteoarthritis - a systematic review

BACKGROUND

Posttraumatic wrist osteoarthritis is an irreversible and often progressive condition. Many surgical treatments, used in (daily) practice, aim to relieve symptoms like pain and restore function. The aim of this systematic review is to assess the patient reported and functional outcomes of the most common surgical interventions in patients with posttraumatic wrist osteoarthritis. This overview can help clinicians select the best treatment and manage patient's expectations.

METHODS

A literature search was performed in Pubmed, Embase and Cochrane for articles published between 1990 and November 2022 according to the PRISMA guidelines. The study protocol has been registered in the PROSPERO database (CRD42017080427). Studies that describe patient reported outcomes (pain and Disability of Arm, Shoulder and Hand (DASH) -score) and functional outcomes (range of motion (ROM) and grip strength) after surgical intervention with a minimal follow-up of 1 year were included. The identified surgical procedures included denervation, proximal row carpectomy, interpositional- and total arthroplasty, and midcarpal-, radiocarpal- and total arthrodesis. The pre-and postoperative outcomes were pooled and presented per salvage procedure.

RESULTS

Data from 50 studies was included. Pain score improved after all surgeries except denervation. Flexion/extension decreased after radiocarpal arthrodesis, did not show significant changes after proximal row carpectomy, and improved for all other surgeries. DASH score improved after arthroplasty, proximal row carpectomy and midcarpal arthrodesis. Grip strength improved after interposition arthroplasty and partial arthrodesis.

CONCLUSION

Evidence from this review did not support the indication for denervation in this particular patient population. In patients with SLAC/SNAC II, proximal row carpectomy might be favourable to a midcarpal arthrodesis solely based on better FE ROM of the radiocarpal joint after proximal row carpectomy. In terms of radiocarpal mobility, total wrist arthroplasty might be preferred to radiocarpal arthrodesis in patients with osteoarthritis after a distal radius fracture. More uniform measurements of outcomes would improve the understanding of the effect of surgical treatments of the posttraumatic osteoarthritic wrist.

Complications after total wrist arthroplasty

We reviewed the incidence and management of complications after total wrist arthroplasty, as reported in the literature, with so-called fourth-generation implants and other recent designs. While early intraoperative and postoperative complications, including fractures, tendon lacerations, infection, nerve compression, tendonitis, stiffness and chronic regional pain syndrome, had an acceptable incidence, late complications, such as periprosthetic osteolysis and implant loosening, occurred more frequently. Implant survival at 10 years was in the range of 70%-80% in most publications. Several of the implants have been modified or withdrawn. Instability and dislocation were frequent after a pyrocarbon spacer. Failed arthroplasties can be salvaged by revision arthroplasty or total wrist arthrodesis. Revision arthroplasty has a lower survival rate than primary arthroplasty and does not clearly offer important significant advantages over total wrist arthrodesis in terms of patient-reported outcome measures. Further development of prosthetic design, new materials and more knowledge on patient-related risk factors are needed.

Wrist arthrodesis combined with a bulk bone allograft for implant loosening after total wrist arthroplasty: A case report

Total wrist arthroplasty (TWA) is a challenging procedure for wrist joints severely destroyed by rheumatoid arthritis. The most common postoperative complication of TWAs is the loosening of the carpal component. Revision surgeries for failed TWAs can be complicated owing to severe bone loss and concomitant soft-tissue problems. Here, we report a case (68-year-old woman with a history of rheumatoid arthritis for 24 years) of severe aseptic loosening of semi-constrained TWA and its salvage surgery. During the primary arthroplasty procedure, severe instability at the second through fifth carpometacarpal joints was observed and arthrodesis of these joints was required. The radiographs obtained 9 months after surgery showed loosening of the carpal component. Subsequently, she suffered a stroke, resulting in a loss of follow-up, and higher stress was loaded on her upper extremities during standing and walking. In the radiograph taken at her revisit 25 months after the primary surgery, the subsidence of the carpal component progressed and loosening of the radial component was observed. Total wrist arthrodesis was performed using a bulk bone allograft of the femoral head, combined with a penetrating Wrist Fusion Rod®. Rapid bone union was achieved without soft-tissue irritation. We conclude that wrist arthrodesis with a bulk bone allograft combined with an intramedullary nail is a reasonable option for failed total wrist arthroplasty.

Safety and efficacy of a novel three-dimensional printed microporous titanium prosthesis for total wrist arthroplasty in the treatment of end-stage wrist arthritis

Background: Total wrist arthroplasty is an effective treatment for end-stage wrist arthritis from all causes. However, wrist prostheses are still prone to complications such as prosthesis loosening and periprosthetic fractures after total wrist arthroplasty. This may be due to the wrist prosthesis imprecise matching with patient's bone. In this study, we designed and developed a personalized three-dimensional printed microporous titanium artificial wrist prosthesis (3DMT-Wrist) for the treatment of end-stage wrist joint, and investigated its safety and effectiveness. Methods: Total wrist arthroplasty was performed using 3DMT-Wrist in 14 cases of arthritis between February 2019 and December 2021. Preoperative and postoperative visual analog scale scores, QuickDASH scores, wrist range of motion, and wrist grip strength were evaluated. Data were statistically analyzed using the paired samples t-test. Results: After 19.7 ± 10.7 months of follow-up, visual analog scale decreased from 66.3 ± 8.9 to 6.7 ± 4.4, QuickDASH scores decreased from 47.4 ± 7.3 to 28.2 ± 7.6, grip strength increased from 5.6 ± 1.4 to 17.0 ± 3.3 kg. The range of motion improved significantly in palmar flexion (30.1° ± 4.9° to 44.9° ± 6.5°), dorsal extension (15.7° ± 3.9° to 25.8° ± 3.3°), ulnar deviation (12.2° ± 3.9° to 20.2° ± 4.3°) and radial deviation (8.2° ± 2.3° to 16.2 ± 3.1). No dislocation or loosening of the prosthetic wrist joint was observed. Conclusion: Total wrist arthroplasty using 3DMT-Wrist is a safe and effective new treatment for various types of end-stage wrist arthritis; it offers excellent pain relief and maintains the range of motion.

La artroplastia de muñeca como solución a la artrosis postraumática o fracaso de artrodesis parcial: Una serie de casos

Introducción Diferentemente de la artrodesis, la artroplastia total de muñeca permite mantener um rango de movimiento funcional en pacientes operados por artrosis de diferentes causas. La evolución de los implantes pemitió llegar a una mayor tasa de éxito, con disminución de las complicaciones como el aflojamiento de componentes. Este estudio tiene como objetivo demostrar los resultados funcionales y las tasas de complicaciones en una serie de casos operados con el implante Motec (Swemac Orthopaedics AB, Linköping, Suecia) por un único cirujano.

Materiales y Métodos Se trata de un estudio retrospectivo con 14 pacientes intervenidos de artroplastia total de muñeca con el sistema Motec entre 2017 y 2022 y evaluados pre y posoperatoriamente por la Escala de Muñeca de la Clínica Mayo (Mayo Wrist Score, en inglés) y la Escala Visual Analógica (EVA). Se realizó revisión de historias clínicas en junio de 2022 y análisis estadístico con prueba t pareada considerando significativos valores de p < 0,05.

Resultados Fueron operados 13 hombres y 1 mujer, con una edad media de 64,8 (desviación estándar [DE] = 7,5) años, y el tiempo medio de seguimiento fue de 25,1 (DE = 10,9) meses. La puntuación en la Escala de Mayo presentó media preoperatoria de 23,2 (DE = 8,9) y posoperatoria de 82,8 (DE = 7), mientras la EVA preoperatoria tuvo una media de 7,6 (DE = 1,1), y la posoperatoria fue de 1 (DE = 1,2). Las diferencias en los resultados pre y posoperatorios de la Escala de Mayo y la EVA fueron estadísticamente significativas (p < 0,001).

Conclusión Como se demuestra en esta serie, las mejoras funcionales y en el dolor fueron importantes, no hubo complicaciones mayores en el período de tiempo evaluado, y la prótesis fue capaz de reemplazar las artrodesis parciales que fallaron. Los pacientes deben ser seguidos durante más tiempo, pero con la certeza de que, en caso de fracaso, aún se puede realizar una artrodesis total de muñeca.

Medium-Term Outcomes for Amandys Implant: A 5-Year Minimum Follow-Up of 63 Cases

Background  Amandys is a pyrocarbon interposition implant used as a therapeutic alternative to total wrist fusion (TWF) or total wrist arthroplasty (TWA) in painful and disabling extensive destruction of the wrist. Objective  To review mid-term outcomes in a continuous prospective series of patients who underwent wrist arthroplasty Amandys with a minimum follow-up of 5 years. Methods  Clinical evaluation included a satisfaction survey, pain, two functional scores, the short version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and the Patient-Rated Wrist Evaluation (PRWE), active wrist mobility, and grip strength compared with the contralateral side. Radiological evaluation was used to detect implant subsidence, carpal migration, bone lysis, or implant malposition. All per- and postoperative complications were collected. Results  Fifty-nine patients (63 procedures) were evaluated with a mean follow-up of 7 years; 57% of the patients were males, and the mean age was 58 years. Among the patients, 90% were satisfied or very satisfied. Pain was significantly improved, with a gain of 4/10 ( p  < 0.001). Functional outcomes also improved between the second and fifth year of follow-up. Active mobility was preserved and grip strength was significantly improved by 7 kg ( p  < 0.001). No implant subsidence or carpal migration was observed. Ten patients (11.9%) underwent revision surgery for conflict (1%), rotation (6%), or implant dislocation (5%). All complications and revisions occurred early with no new events after 1 year of follow-up. Discussion  Mid-term clinical and radiological outcomes were stable with improvement of functional scores. The survival rate was comparable to that reported for TWF with conserved mobility. We report fewer complications compared with those reported for TWA or TWF. Early instability of the implant was the main etiology of the revisions. Repositioning of the implant was successful. No conversion to TWA or TWF was necessary. Conclusions  Mid-term outcomes of the Amandys implants were encouraging. Patients conserved good wrist motion with improved strength and functional scores. The implant was well tolerated. Functional outcomes continue to improve with the follow-up. The survival rate remains stable after 2 years. The level of evidence of this study is IV (therapeutic case series).
