Abstract
BACKGROUND Revision of radial head arthroplasty (RHA) may be indicated in cases of prosthesis loosening and malposition. Inherent difficulties in revision surgery include poor bone stock and disrupted soft tissue envelope. Although cases of RHA used for revision of failed RHA are rare, there is reasonable expectation for increasing frequency of these cases due to the increasing incidence of primary RHA. Furthermore, there is an increasing demand for postoperative recovery of function; thus, surgeons may consider revising a failed RHA to a new RHA. We report on series of failed RHA which were revised to a new radial head prosthesis. METHODS A retrospective review was performed at multiple institutions for a single radial head prosthesis used for revision of a failed radial head prosthesis. Clinical and radiographic outcomes were collected with a minimum of 1 year of follow-up. RESULTS Across 11 patients at a mean follow-up of 45.1 months, the mean Mayo Elbow Performance Score was 81.7; mean Disabilities of the Arm, Shoulder, and Hand scores were 24.4; and mean Visual Analog Scale for pain was 0.6. Radiographic analysis yielded no evidence of capitellar wear or stem loosening. CONCLUSION A radial head prosthesis can produce satisfactory results when used for revision of a failed prosthesis. Inherent difficulties in revision surgery include the potential for reduced bone stock and a disrupted soft tissue envelope. Elements of prosthesis design which may contribute to effectively managing revision surgery include a long stem with in-growth surface and prosthetic head alignment to the axis of forearm rotation.

Abstract
PURPOSE Current teaching suggests that modified Mason type III and IV fractures of the radial head involving more than 3 fragments should be treated with radial head arthroplasty. The purpose of this study was to compare the outcome of simple (2 or fewer intra-articular pieces) versus comminuted (3 or more intra-articular pieces) radial head fractures treated with open reduction internal fixation (ORIF). METHODS This was a retrospective review of 35 patients with modified Mason type III and IV fractures treated with ORIF. For the purpose of our study, simple fractures were defined as having 2 or fewer intra-articular fragments. Comminuted fractures were defined as having 3 or more intra-articular fragments. The primary outcomes were Broberg and Morrey rating system and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores. Reoperation rates and complications were also noted. RESULTS Thirty-five patients were evaluated, with a mean follow-up of 39.3 months. Thirteen patients had radial head fractures consisting of 2 or fewer intra-articular fragments. Twenty-two patients had radial head fractures consisting of 3 or more intra-articular fragments. Ages and follow-up times were similar in the 2 groups. Similar QuickDASH and Broberg and Morrey scores were seen when evaluating subgroups of 2, 3, and 4 fragment fractures. One patient from each group underwent revision surgery for symptomatic hardware. CONCLUSIONS In our series, we found similar clinical outcome scores and reoperation rates between simple and comminuted radial head fractures treated with ORIF. Fractures with more than 3 intra-articular fragments can be considered for ORIF. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

[PMID: 37354192 DOI: 10.1016/j.jhsa.2023.04.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 04/17/2023] [Accepted: 04/26/2023] [Indexed: 06/26/2023]
Abstract
PURPOSE The purpose of this study was to evaluate implant survivorship and clinical outcomes following radial head arthroplasty for fracture at long-term follow-ups. METHODS A retrospective analysis was conducted on adult patients who underwent primary uncemented radial head arthroplasty for radial head or neck fractures between 2012 and 2015. Medical records were reviewed to collect information regarding demographics, injury characteristics, reoperations, and revisions requiring implant removal. A bivariate analysis was conducted to identify potential risk factors for reoperation. A Kaplan-Meier curve was created to determine implant survival rates. Eligible patients were contacted to confirm any reoperations and obtain Quick Disability of the Arm, Shoulder, and Hand scores at long-term follow-ups. RESULTS A total of 89 patients were eligible for analysis and assessed at a mean of 97 months after surgery (range, 81-128). Reoperation rate was 16% (14 of 89 patients), including 5% of patients requiring implant removal or revision. However, 93% of reoperations occurred within the first 12 months of the index surgery. Fracture dislocations of the elbow had a higher rate of reoperation. A Kaplan-Meier curve demonstrated an implant survival rate of 96% at 10-year follow-up. Of the patients who responded, the mean Quick Disability of the Arm, Shoulder, and Hand score was 8.7 ± 10.3, with none requiring additional reoperations or revisions. There were otherwise similar outcome scores among patients requiring reoperation versus those who did not. CONCLUSIONS Although radial head arthroplasty for fractures has a high potential for reoperation within the first year, survival rates with uncemented implants remain high at 10 years, and patients report excellent Quick Disability of the Arm, Shoulder, and Hand scores at long-term follow-ups, despite any need for reoperation. Fractures with associated elbow dislocation may be at a higher risk for reoperation, and it is important to provide this prognostic information to patients who are likely to require arthroplasty for more extensive injuries.

Is implant choice associated with fixation strength for displaced radial neck fracture: a network meta-analysis of biomechanical studies. Sci Rep 2023; 13:6891. [PMID: 37105993 PMCID: PMC10140263 DOI: 10.1038/s41598-023-33410-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 04/12/2023] [Indexed: 04/29/2023] Open
Abstract
The multitude of fixation options for radial neck fractures, such as pins, screws, biodegradable pins and screws, locking plates, and blade plates, has led to a lack of consensus on the optimal implant choice and associated biomechanical properties. This study aims to evaluate the biomechanical strength of various fixation constructs in axial, sagittal, and torsional loading directions. We included biomechanical studies comparing different interventions, such as cross/parallel screws, nonlocking plates with or without augmented screws, fixed angle devices (T or anatomic locking plates or blade plates), and cross pins. A systematic search of MEDLINE (Ovid), Embase, Scopus, and CINAHL EBSCO databases was conducted on September 26th, 2022. Data extraction was carried out by one author and verified by another. A network meta-analysis (NMA) was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Primary outcomes encompassed axial, bending, and torsional stiffness, while the secondary outcome was bending load to failure. Effect sizes were calculated for continuous outcomes, and relative treatment ranking was measured using the surface under the cumulative ranking curve (SUCRA). Our analysis encompassed eight studies, incorporating 172 specimens. The findings indicated that fixed angle constructs, specifically the anatomic locking plate, demonstrated superior axial stiffness (mean difference [MD]: 23.59 N/mm; 95% CI 8.12-39.06) in comparison to the cross screw. Additionally, the blade plate construct excelled in bending stiffness (MD: 32.37 N/mm; 95% CI - 47.37 to 112.11) relative to the cross screw construct, while the cross-screw construct proved to be the most robust in terms of bending load failure. The parallel screw construct performed optimally in torsional stiffness (MD: 139.39 Nm/degree; 95% CI 0.79-277.98) when compared to the cross screw construct. Lastly, the nonlocking plate, locking T plate, and cross-pin constructs were found to be inferior in most respects to alternative interventions. The NMA indicated that fixed angle devices (blade plate and anatomic locking plate) and screw fixations may exhibit enhanced biomechanical strength in axial and bending directions, whereas cross screws demonstrated reduced torsional stability in comparison to parallel screws. It is imperative for clinicians to consider the application of these findings in constraining forces across various directions during early range of motion exercises, taking into account the distinct biomechanical properties of the respective implants.

Abstract
OBJECTIVE Radial head arthroplasty (RHA) is the principal treatment option for comminuted radial head (RH) fractures. Here, we present six cases of failed RHA using a modular monopolar press-fit RHA that was subsequently withdrawn from the market because it was associated with a high incidence of loosening. METHODS We retrospectively collected data from six patients who had received Radial Head Prothesis SystemTM at our centre between July 2015 and June 2016. The average follow-up was 40 months. RESULTS Aseptic loosening of the stem affected five (83%) of the six RHA. Four of these were symptomatic and RHA removal was performed. For these patients, the pain subsided and their elbow range of motion (ROM) improved. CONCLUSION While the ideal design for an RHA is still debatable, RHA is an efficient treatment option that restores elbow stability and function after a comminuted RH fracture. Importantly, removal of the prosthesis is an effective remedy following RHA associated elbow pain and decreased ROM.

Abstract
INTRODUCTION Radial head arthroplasty and open reduction internal fixation are two commonly utilized treatment options for radial head fractures. The purpose of this study is to assess the incidence of and risk factors for short-term complications following radial head arthroplasty and open reduction internal fixation of radial head fractures. METHODS The American College of Surgeons National Surgical Quality Improvement Program was queried to identify patients that underwent radial head arthroplasty or open reduction internal fixation for radial head fractures between January 1st, 2015 and December 31st, 2017. The incidence of various 30-day complications, including unplanned readmission, reoperation, non-home discharge, mortality, surgical/medical complications, and extended length-of-stay were compared between the two propensity matched groups. Multivariate logistic regression was used to identify independent risk factors for various short-term complications. RESULTS After propensity matching, a total of 435 patients were included in our analysis. 250 patients underwent radial head arthroplasty, and 185 patients underwent open reduction internal fixation. Arthroplasty treated patients had a significantly longer mean total operative time (p = .031) and length-of-stay (p = .003). No significant 30-day complications differences were found for unplanned readmission, reoperation, non-home discharge, mortality, surgical complications or medical complications. Independent risk factors for any complications of both procedures included a history of chronic obstructive pulmonary disease and American Society of Anesthesiologists class III. Significant risk factors for length-of-stay greater than two days included a history of bleeding disorder and American Society of Anesthesiologists class III. CONCLUSION Our study revealed there were no significant differences in 30-day perioperative surgical or medical complications from either surgical treatment of radial head fractures; however, radial head arthroplasty treated patients were met with a significantly longer length-of-stay and longer duration of operating time. We also identified risk factors that were independently associated with higher rates of complications regardless of treatment type.

Abstract
BACKGROUND The purpose of this study was to systematically review the literature to evaluate the functional outcomes, radiologic outcomes, and revision rates following radial head arthroplasty (RHA) at a minimum of 8 years follow-up. METHODS Two independent reviewers performed a literature search using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines using PubMed, Embase, and Web of Science databases. Only studies reporting on outcomes of RHA with a minimum of mean 8 years' follow-up were considered for inclusion. RESULTS Our search found 10 studies including 432 elbows (51% males), with average age of 50 years (15-93) and mean follow-up of 117 months (98-145) met our inclusion criteria. At final follow-up, the mean Mayo Elbow Performance Score and Quick Disabilities of the Arm, Shoulder, and Hand questionnaire score were 83 (45-100) and 17 (0-63) respectively, and 86% of patients reported having no or minimal pain. The overall dislocation, subluxation, ulnar neuritis, and infection rates were 2%, 4%, 3%, and 3%, respectively. The rates of radiologic loosening, radiolucency, degenerative change, and heterotopic ossification were 9%, 46%, 27%, and 38%, respectively. The overall surgical revision rates were 20%, with 3%, 15%, and 5% requiring RHA implant revision, removal of metal or implants, and arthrolysis, respectively. CONCLUSION Our systematic review established that RHA results in satisfactory clinical outcomes and modest complication and revision rates at long-term follow-up, despite high levels of radiologic degenerative changes over the same period.

Abstract
OBJECTIVES To determine outcomes of radial head replacement (RHR) for acute fractures using 3 different implant designs with or without cement fixation. DESIGN Retrospective. SETTING Tertiary referral hospital. PATIENTS/PARTICIPANTS One hundred fourteen elbows underwent RHR for an acute radial head fracture using either (1) a nonanatomic design and smooth stem (n = 60), (2) a nonanatomic design with a grit-blasted, ingrowth, curved stem (n = 21), or (3) an anatomic design with a grit-blasted ingrowth straight stem (n = 33). Cemented (25%) or uncemented (75%) fixation was used at the discretion of the treating surgeon. INTERVENTION RHR. MAIN OUTCOME MEASUREMENTS The primary outcome was implant survivorship free of revision or removal for any reason. All elbows were evaluated clinically (the Mayo Elbow Performance Score and reoperations/complications) and radiographically. RESULTS Fourteen implants (12%) were revised. Of elbows with a minimum 2-year clinical follow-up, the average Mayo Elbow Performance Score was 88. The rate of survivorship free from revision was 92% [95% confidence interval (CI) = 87%-98%] at 2 years, 90% (CI = 84%-96%) at 5 years and 84% (CI = 75%-94%) at 10 years. The differences in survivorship between the 3 implants did not reach statistical significance, but the nonanatomic design with a grit-blasted ingrowth curved stem had a hazard ratio of 4.6 (95% CI = 0.9%-23%) for failure. There were no differences in survivorship between cemented versus uncemented stems. For those elbows with a minimum of 2 years of radiographic follow-up, implant tilt was observed in 10 (16%) elbows and loosening in 16 (26%) elbows. Stress shielding was present in 19 (42%) of well-fixed implants. CONCLUSIONS RHR for acute trauma leads to survivorship greater than 80% at 10 years. Radiographic changes (loosening, stress shielding, and implant tilting) can be expected in a substantial portion of elbows at long-term follow-up. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
INTRODUCTION When treating comminuted radial head fractures that cannot be adequately fixed, the next option is arthroplasty (radial head replacement). We hypothesized that the radiological and functional outcomes of bipolar mobile cup radial head arthroplasty is not influenced by the length of follow-up but instead by the correct positioning of the implant intraoperatively and by the presence of associated bone or ligament injuries. PATIENTS AND METHODS Between May 1998 and December 2016, 82 cases of radial head arthroplasty were performed at our hospital. The mean age of patients at the time of arthroplasty was 53 years (22-81). Ligament or bone injuries complicated the radial head fractures in 70% of patients. RESULTS For the final assessment, 41 patients were reviewed and included in the statistical analysis with a mean of 82 months (12-228). The mean MEPS at the final assessment was 88.7 (61-100). There were 23 excellent, 9 good, 9 average and 0 poor results. The average DASH score was 18.7 (0-55). The average VAS for pain was 1.0 (0-5). Five patients (12%) required surgical revision, including one implant change. Our statistical analysis found no relationship between follow-up time and functional outcomes. The appearance of periprosthetic radiolucent lines was not affected by the length of follow-up. Associated bone or ligament injuries significantly increased the probability of periprosthetic radiolucent lines, humeroulnar joint degeneration and decentering of the implanted cup. Radiological evidence of a suspended implant was associated with significantly worse functional outcomes. CONCLUSION This study confirms the long-term stability of the clinical outcomes of radial head arthroplasty. There was no relationship between worsening radiological appearance of the implant and the clinical outcomes. It is critical that this implant not be oversized or suspended, as this can trigger premature capitellar erosion and painful stiffness of the operated elbow.

Abstract
Introduction The objectives of this study were to assess long-term outcomes, complications, and reoperations after open reduction internal fixation (ORIF) of radial head fractures. Materials and Methods 35 adult patients, who underwent ORIF of an isolated, displaced radial head fracture without elbow instability (Mason classification type II or III) at two tertiary care referral centers from 2000 to 2017, were identified. Patient satisfaction, pain, and QuickDASH scores were assessed by telephone follow-up at median 12.9 years. Results The mean age of the 35 patients in our study was 39 years, and 54% were women. The median length of clinical follow-up was 175 days. Postoperative complications occurred in 54% of patients, and reoperations in 23% of patients. Multivariable logistic regression identified fixation with plate and screws versus screws alone as a risk factor for complications and reoperations. The long-term telephone follow-up response rate was 54%. At 13-year median follow-up, the average patient satisfaction was 9.6/10, the average patient-reported pain was 0.7/10, and the average QuickDASH score was 10.5. Conclusion The long-term outcomes of ORIF of Mason classification type II and III radial head fractures are favorable; however, rates of complication and reoperation are notable and may be higher with plate-and-screw fixation.

The elbow joint consists of the humeroulnar, humeroradial, and proximal radioulnar joints. Elbow stability is maintained by a combination of static and dynamic constraints. Elbow fractures are challenging to treat because the articular surfaces must be restored perfectly and associated soft tissue injuries must be recognized and appropriately managed. Most elbow fractures are best treated operatively with restoration of normal bony anatomy and rigid internal fixation and repair and/or reconstruction of the collateral ligaments. Advanced imaging, improved understanding of the complex anatomy of the elbow joint, and improved fixation techniques have contributed to improved elbow fracture outcomes.

Abstract
Background Numerous fixed-stem implants exist for radial head arthroplasty; therefore, we conducted a systematic review to compare the safety and efficacy of different types of fixed-stem implants. Methods We conducted a literature search, updated from a previous systematic review, to identify studies evaluating a fixed-stem radial head arthroplasty implant for any indication. We extracted data on revision rates, specific complications, and functional scores. We pooled results across studies using a random-effects method, using proportions for dichotomous data and mean values for functional scores. We analyzed outcomes by indication and specific implant. Results We included 31 studies. Studies included patients with radial head fractures only, terrible-triad injuries, or Essex-Lopresti injuries or included a heterogeneous population. We identified 15 different fixed-stem implants. The results of our analysis revealed that patients with terrible-triad injuries may be at an increased risk of revision and instability and patients with Essex-Lopresti injuries may be at an increased risk of arthritis, capitellar erosion, and osteolysis. After removing these outliers and pooling the results by specific device, we observed variability across devices in the rates of revision, arthritis, capitellar erosion, instability, and osteolysis, as well as in functional scores. Conclusion Differences were seen across different implants in revision rates, certain complications, and functional scores. This study highlighted that these devices should be evaluated within the context of the patient population under examination, as patients with Essex-Lopresti or terrible-triad injuries may demonstrate worse outcomes relative to those with a fracture only.

Abstract
Radial head fractures are common injuries comprising 1/3 of the fractures about the elbow. As a secondary valgus stabilizer of the elbow, radial head fractures can compromise elbow stability leading to long-term pain, dysfunction, and degenerative change. Furthermore, radial head fractures can be accompanied by associated injuries including ligamentous lesions that can further exacerbate elbow instability, leading to long-term sequelae. As fixation principles and technology have evolved, so has the ability to render surgical treatment for these fractures. In general, minimally displaced and some displaced fractures may be treated nonoperatively with early motion. Fractures with a block to rotation and displaced fragments with 3 or fewer fragments may be treated with open reduction and internal fixation. Comminuted fractures or those with greater than 3 fragments may be successfully treated with radial head replacement. Associated elbow instability will also influence treatment decisions.

High Risk of Further Surgery After Radial Head Replacement for Unstable Fractures: Longer-term Outcomes at a Minimum Follow-up of 8 Years. Clin Orthop Relat Res 2019; 477:2531-2540.

Abstract
BACKGROUND The evidence for treating acute, unreconstructable radial head fractures in unstable elbows with radial head replacement predominantly consists of short- to mid-term follow-up studies with a heterogenous mix of implants and operative techniques. Data on longer-term patient-reported outcomes after radial head replacement is lacking. QUESTIONS/PURPOSES (1) What proportion of patients undergo revision or implant removal after radial head replacement? (2) At a minimum of 8 years follow-up, what are the patient-reported outcomes (QuickDASH, Oxford Elbow Score, and EuroQol-5D)? (3) What factors are associated with a superior long-term patient-reported outcome, according to the QuickDASH? METHODS Between September 1994 and September 2010, we surgically treated 157 patients for acute radial head fractures. We excluded patients where the radial head was excised (n = 21), internally fixed (n = 15), or replaced as a secondary procedure after failed internal fixation (n = 2). A total of 119 patients who underwent radial head replacement surgery for an acute unreconstructable fracture were included, with a mean age of 50 years (range 15 to 93 ± 19 years), and 53% of patients (63) were women. All but two implants were uncemented, loose-fitting, monopolar prostheses, of which 86% (102) were metallic and 14% (17) were silastic. Implants were only cemented if they appeared unstable within the proximal radius. Silastic implants were used in the earlier series and replaced by metallic implants starting in 2000. We reviewed electronic records to document postoperative complications and prosthesis revision and removal. A member of the local research team (THC, CDC) who was not previously involved in patient care contacted patients to confirm complications, reoperations and to obtain long-term patient-reported outcomes scores. Nineteen patients had died at the point of outcome score collection. Of the remaining 100 patients, 80 were contacted (67% of total cohort), at a median of 11 years (range 8 to 24 years) after injury. The primary outcome measure was the QuickDASH score. RESULTS Of 119 patients, 25% (30) underwent reoperation, with three patients undergoing revision and 27 patients undergoing prosthesis removal at a median of 7 months (range 0 to 125 months). Twenty-one of 30 procedures (70%) occurred within 1 year after implantation. Kaplan-Meier survivorship analysis demonstrated a cumulative implant survival rate of 71%. In the 80 patients contacted, the mean QuickDASH score was 13 ± 14, the mean Oxford Elbow Score was 43 ± 6, and the median EuroQol-5D score was 0.8 (-0.3 to 1.0). After controlling for covariates, we found that prothesis revision or removal (p = 0.466) and prosthesis type (p = 0.553) were not associated with patient-reported outcome, according to the QuickDASH. CONCLUSIONS The management of acute unreconstructable fractures of the radial head in unstable elbow injuries with radial head replacement has a high risk of reoperation. Patients must be counselled regarding this risk of secondary intervention, of which the peak risk appears to be within 1 year after implantation. Despite this, patients report low disability according to the QuickDASH at a minimum follow-up of 8 years. LEVEL OF EVIDENCE Level IV, therapeutic study.
