Aims

Arthroplasties of the elbow, including total elbow arthroplasty, radial head arthroplasty, distal humeral hemiarthroplasty, and radiocapitellar arthroplasty, are rarely undertaken. This scoping review aims to outline the current research in this area to inform the development of future research.

Aims. This study aimed to determine the minimal detectable change (MDC), minimal clinically important difference (MCID), and substantial clinical benefit (SCB) under distribution- and anchor-based methods for the Mayo Elbow Performance Index (MEPI) and range of movement (ROM) after open elbow arthrolysis (OEA). We also assessed the proportion of patients who achieved MCID and SCB; and identified the factors associated with achieving MCID. Methods. A cohort of 265 patients treated by OEA were included. The MEPI and ROM were evaluated at baseline and at two-year follow-up. Distribution-based MDC was calculated with confidence intervals (CIs) reflecting 80% (MDC 80), 90% (MDC 90), and 95% (MDC 95) certainty, and MCID with changes from baseline to follow-up. Anchor-based MCID (anchored to somewhat satisfied) and SCB (very satisfied) were calculated using a five-level Likert satisfaction scale. Multivariate logistic regression of factors affecting MCID achievement was performed. Results. The MDC increased substantially based on selected CIs (MDC 80, MDC 90, and MDC 95), ranging from 5.0 to 7.6 points for the MEPI, and from 8.2° to 12.5° for ROM. The MCID of the MEPI were 8.3 points under distribution-based and 12.2 points under anchor-based methods; distribution- and anchor-based MCID of ROM were 14.1° and 25.0°. The SCB of the MEPI and ROM were 17.3 points and 43.4°, respectively. The proportion of the patients who attained anchor-based MCID for the MEPI and ROM were 74.0% and 94.7%, respectively; furthermore, 64.2% and 86.8% attained SCB. Non-dominant arm (p = 0.022), higher preoperative MEPI rating (p < 0.001), and postoperative visual analogue scale pain score (p < 0.001) were independent predictors of not achieving MCID for the MEPI, while atraumatic causes (p = 0.040) and higher preoperative ROM (p = 0.005) were independent risk factors for ROM. Conclusion. In patients undergoing OEA, the MCID for the increased MEPI is 12.2 points and 25° increased ROM. The SCB is 17.3 points and 43.3°, respectively. Future studies using the MEPI and ROM to assess OEA outcomes should report not only statistical significance but also clinical importance. Cite this article: Bone Joint J 2021;103-B(2):366–372

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

Aims

The aim of this study was to report the mid-term clinical outcome of cemented unlinked J-alumina ceramic elbow (JACE) arthroplasties when used in patients with rheumatoid arthritis (RA).

Aim

The aim of this study was to report the long-term outcome and implant survival of the lateral resurfacing elbow (LRE) arthroplasty in the treatment of elbow arthritis.

Background. The optimal treatment for symptomatic elbow osteoarthritis remains debatable especially in patients still involved in heavy manual work. The Outerbridge-Kashiwagi (OK) procedure has been used when simple measures fail. The aim of this study is to analyse the results of the OK procedure in patients with symptomatic osteoarthritis. Methods. Twenty-two patients were included in the study. The male:female ratio was 18:4. The mean age was 60 years with mean follow-up of 38 months (24–60 months). 17 were manual workers, 3 involved in sports activities and 2 non-manual workers. All patients were assessed using Mayo Elbow Performance Index Score system. Preoperative radiological assessment showed osteophytes around olecranon and coronoid process and joint space narrowing in radio-humeral articulationin all cases. Results. There was a significant improvement (p<0.05) in movement in the flexion-extension axis from 78.2° to 107.3°. There was a significant reduction in pain post-operatively (p<0.001). Mean MEPI score improved from 50 to 87.4 post surgery which was significant (p<0.05). One patient had ulnar nerve palsy which resolved in six months with conservative management. The results were excellent in six patients (27%), good in fifteen (68%), fair in one (5%) and one (5%) had poor result. Discussion and conclusion. The present study indicates that the OK procedure provides significant pain relief and a functionally useful range of movement of more than 100°. The procedure can be used in high demand patients, wherein total elbow replacement is not indicated. It significantly reduces the disability in patients with significant elbow arthritis

We retrospectively evaluated the clinical and radiological outcomes of a consecutive cohort of patients aged > 70 years with a displaced fracture of the olecranon, which was treated non-operatively with early mobilisation. We identified 28 such patients (27 women) with a mean age of 82 years (71 to 91). The elbow was initially immobilised in an above elbow cast in 90° of flexion of the elbow for a mean of five days. The cast was then replaced by a sling. Active mobilisation was encouraged as tolerated. No formal rehabilitation was undertaken. At a mean follow-up of 16 months (12 to 26), the mean ranges of flexion and extension were 140° and 15° respectively. On a visual analogue scale of 1 (no pain) to 10, the mean pain score was 1 (0 to 8). Of the original 28 patients 22 developed nonunion, but no patients required surgical treatment.

We conclude that non-operative functional treatment of displaced olecranon fractures in the elderly gives good results and a high rate of satisfaction.

Most fractures of the radial head are stable undisplaced or minimally displaced partial fractures without an associated fracture of the elbow or forearm or ligament injury, where stiffness following non-operative management is the primary concern. Displaced unstable fractures of the radial head are usually associated with other fractures or ligament injuries, and restoration of radiocapitellar contact by reconstruction or prosthetic replacement of the fractured head is necessary to prevent subluxation or dislocation of the elbow and forearm. In fractures with three or fewer fragments (two articular fragments and the neck) and little or no metaphyseal comminution, open reduction and internal fixation may give good results. However, fragmented unstable fractures of the radial head are prone to early failure of fixation and nonunion when fixed. Excision of the radial head is associated with good long-term results, but in patients with instability of the elbow or forearm, prosthetic replacement is preferred.

This review considers the characteristics of stable and unstable fractures of the radial head, as well as discussing the debatable aspects of management, in light of the current best evidence.

Introduction. The action of the radial head in the stability of the elbow is currently admitted. Its conservation is not always possible in complex fractures. The association with a posterolateral dislocation of the elbow leads to a higher risk of instability of the elbow joint and also at a longer term to degenerative changes. Some authors recommend the use of metallic radial head implant, acting as a spacer. The results seems encouraging but should the resection arthroplasty associated with the repair of the medial collateral ligament be abandoned?. Material and methods. In an amount of 35 consecutive patients who were taken in charge for an elbow dislocation 26 were included in this retrospective study, 13 of them had the association of a dislocation and a fracture of the radial head. In all 13 cases the radial head was considered as inadequate with a conservative treatment and was resected. The patients were assessed clinically according to the American Shoulder and Elbow Surgeons score (ASES) and the Mayo elbow performance index with a mean follow-up of 13 years (ranging from 5 to 15). The degenerative changes were assessed on plan × rays and an additional axial view according to the 4 stages described by Morrey. Results. No redislocation occurred. According to the Broberg/Morrey index 92% of the patients were considered as having a good result. They returned to work with no hindering. Signs of osteoarthritis grade 1 or 2 were observed and were clinically well tolerated. There was no difference for this item between the patients who conserved their radial head and those who sustained a resection. All patients were satisfied although they were protecting their joint against overuse while working. Discussion. The studies about the use of prosthesis of the radial head offer similar functional results. Degenerative changes on the trochleo ulnar joint are identical in all type of treatment. In order to prevent stiffness in the elbow joint an early post operative rehabilitation is recommended, it justifies a surgical stabilization associated with the use of an adapted dynamic splint. Conclusion. In case of elbow dislocation with a fracture of the radial head when its preservation is impossible, the resection without any prosthetic replacement remains a reasonable option if associated with a repair of the medial collateral ligament. At long term the functional results are still good with mild signs of osteoarthritis eliminating ipso facto the problem of an implant survivorship

Purpose. Evaluation of our experience on the treatment of comminuted, radial head fractures, and of the outcomes of pyrocarbon prosthetic replacement in such cases. Materials and Methods. We evaluated 47 cases of prosthetic replacement, performed from May 2003 to July 2008. There were 18 males and 29 females with an average follow-up of 48 months (12 to 60). The Hotchkiss classification was used to characterize the fractures. The indicators for the procedure were type III fractures in 27 cases, type IV fractures in 10 cases, comminuted radial head fractures (associated with disruption in medial collateral ligament) in 3 cases, Monteggia variant in 5 cases, and Essex Lopresti in 2 cases. Functional outcomes were assessed using the Mayo Elbow Performance Index and the Visual Analog Scales (VAS) of pain, joint motion, and stability. Results. The mean VAS score for elbow pain was 1 (0.5–2.1). Patients showed an average arch of motion from 6 degrees to 140, with 75 degrees of pronation, and 67 of supination. By the Mayo Elbow Performance Index, 42 patients had good to excellent results, 3 fair, and 2 poor. The complications that we have encountered were: implant dislocations (2 cases), elbow stiffness (1), implant dissociation (1), stem rupture (1), and transient PIN palsy (2 cases with complete recovery of nervous function at 5 and 8 weeks). There was no persistent instability, infection, synosthosis, severe degenerative changes, or impingement. Conclusion. The pyrocarbon implants are a good treatment option in complicated, radial head fractures, but the outcome depends on the severity of the initial fracture and the associated lesions. We have also encountered a tendency towards overestimating the prosthesis size, causing restriction of motion, impingement, overstuffing, or dislocation. For these results we are now using the non-modular prosthesis in our center, but further studies are required

Background. Comminuted radial head fractures are challenging to treat with open reduction and internal fixation. Complicating matters further, radial head fractures are often associated with other elbow fractures and soft tissue injuries. Radial head arthroplasty is a favorable technique for the treatment of radial head fractures. The purpose of this study was to evaluate the functional outcomes of radial head arthroplasty using Modular Pyrocarbon radial head prosthesis in patients with unreconstructible radial head fractures. Methods. This single surgeon, single centre study retrospectively reviewed the functional and radiological outcomes of 21 consecutive patients requiring radial head arthroplasty for unreconstructible radial head fractures between July 2003 and July 2009. Patients were at least one year post-op and completed a Short-Form 36 (SF-36) questionnaire, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and the Mayo Elbow Performance Index (MEPI). These patients were independently physically examined and their post-operative radiographs were independently reviewed. Results. 21 patients (9 males and 12 females) were reviewed at a minimum of 12 months follow-up. The mean DASH score was 10.8 (0-34.1), the mean SF-36 physical score was 76.9 (35-96), the mean SF-36 mental score was 83.8 (60-94), and their MEPI score was 86.4 (70-100). Patients maintained 90% of their grip strength in their injured arm when compared to their un-injured arm and had 17. o. of fixed flexion in the affected arm. Radiologically, 14 cases had some degree of post-traumatic osteoarthritis, 12 cases had evidence of heterotrophic ossification, 5 had some evidence of periprosthetic lucency and 3 of our cases were radiologically but not functionally ‘overstuffed’. Conclusion. Radial Head Arthroplasty with Pyrocarbon Radial Head Prosthesis is a safe and effective option when treating unreconstructable comminuted radial head fractures yielding good functional and radiological outcomes and remains the treatment option of choice at our institution

This study reviews the early results of Distal Humeral Hemiarthroplasty(DHH) for distal humeral fracture and proposed a treatment algorithm incorporating the use of this technique in the overall management of distal humeral fractures. DHH was performed on 30 patients (mean 65 years; 29-91) for unreconstructable fractures of the distal humerus or salvage of failed internal fixation. A triceps on approach was used in six and an olecranon osteotomy in 24. A Sorbie Questor prosthesis (Wright Medical Technology) was used in 14 patients and a Latitude (Tornier) in 16. Clinical review at a mean of 25 months (3–88) included the American Shoulder and Elbow Surgeons elbow outcomes instrument (ASES), Mayo Elbow Performance Index (MEPI) and radiological assessment. At follow up of 28 patients mean flexion deformity was 25 degrees, flexion 128 degrees, range of pronosupination 165 degrees, mean ASES 83, MEPI 77 and satisfaction 8/10. Acute cases scored better than salvage cases. Re- operation was required in 16 patients (53%); two revisions to a linked prosthesis for periprosthetic fracture and aseptic loosening at 53 and 16 months, 12 metalwork removals and four ulnar nerve procedures. Posterolateral rotatory instability was present in one elbow, four had laxity and mild pain on loading (two with prosthesis or pin loosening), four had laxity associated with column fractures (two symptomatic) and 10 had asymptomatic mild laxity only. The triceps on approach had worse instability and clinical scores. Uncomplicated union occurred in all olecranon osteotomies and 86% of column fractures. One elbow had an incomplete cement mantle and seven had lucencies >1 mm; one was loose but acceptable. Five prostheses were in slight varus. Two elbows had early degenerative changes and 15 developed a medial spur on the trochlea. This is the largest reported experience of DHH. Early results of DHH show good outcomes after complex distal humeral fractures, despite a technically demanding procedure. Better results are obtained for treatment in the acute setting and with use of an olecranon osteotomy. As a result of this experience anatomical and clinical pre-requisites and advise on technique are outlined. An algorithm for use of DHH in relation to total elbow arthroplasty and ORIF for the treatment of complex intra-articular distal humeral fractures with or without column fractures is proposed

We studied, ten patients (11 elbows) who had undergone 14 allograft-prosthesis composite reconstructions following failure of a previous total elbow replacement with massive structural bone loss. There were nine women and one man with a mean age of 64 years (40 to 84), who were reviewed at a mean of 75 months (24 to 213). One patient developed a deep infection after 26 months and had the allograft-prosthesis composite removed, and two patients had mild pain. The median flexion-extension arc was 100° (95% confidence interval (CI) 76° to 124°). With the exception of the patient who had the infected failure, all the patients could use their elbows comfortably without splints or braces for activities of daily living. The mean Mayo Elbow Performance Index improved from 9.5 (95% CI 4.4 to 14.7) pre-operatively to 74 (95% CI 62.4 to 84.9) at final review. Radiologically, the rate of partial resorption was similar in the humeral and ulnar allografts (three of six and four of eight, respectively; p > 0.999). The patterns of resorption, however, were different. Union at the host-bone-allograft junction was also different between the humeral and ulnar allografts (one of six and seven of eight showing union, respectively; p = 0.03). At medium-term follow-up, allograft-prosthesis composite reconstruction appears to be a useful salvage technique for failed elbow replacements with massive bone loss. The effects of allograft resorption and host-bone-allograft junctional union on the longevity of allograft-prosthesis composite reconstruction, however, remain unknown, and it is our view that these patients should remain under long-term regular review

Purpose: This study reviews the early results of elbow hemiarthroplasty for distal humeral fractures. Method: Elbow hemiarthroplasty was performed on 30 patients (mean 65 years; 29–91) for unreconstruc-table fractures of the distal humerus or salvage of failed internal fixation. A ‘triceps on’ approach was used in six and an olecranon osteotomy in 24. A Sorbie Questor prosthesis (Wright Medical Technology) was used in 14 patients and a Lattitude (Tornier) in 16. Clinical review at a mean of 25 months (3–88) included the American Shoulder and Elbow Surgeons elbow outcomes instrument (ASES), Mayo Elbow Performance Index (MEPI) and radiological assessment. Results: At follow up of 28 patients mean flexion deformity was 25 degrees, flexion 128 degrees, range of pro-nosupination 165 degrees, mean ASES 83, MEPI 77 and satisfaction 8/10. Acute cases scored better than salvage cases. Re-operation was required in 16 patients (53%); two revisions to a linked prosthesis for periprosthetic fracture and aseptic loosening at 53 and 16 months, 12 metalwork removals and four ulnar nerve procedures. Posterolateral rotatory instability was present in one elbow, four had laxity and pain on loading (two with prosthesis or pin loosening), four had laxity associated with column fractures (two symptomatic) and ten had asymptomatic laxity only. The triceps on approach had worse laxity and clinical scores. Uncomplicated union occurred in all olecranon osteotomies and 86% of column fractures. One elbow had an incomplete cement mantle and seven had lucencies > 1 mm; one was loose but acceptable. Five prostheses were in slight varus and two were flexed. Two elbows had early degenerative changes and 15 developed an osteophytic lip on the medial trochlea. Conclusion: Early results of elbow hemiarthroplasty show good outcomes after complex distal humeral fractures, despite a technically demanding procedure, met-alware removal in 40%, symptomatic laxity in 12% and column non-union in 8%. Better results are obtained for treatment in the acute setting and with use of an olecranon osteotomy

This is a retrospective review of the results of the Acclaim total elbow replacement in 11 older patients aged ≥ 65 years with primary osteoarthritis of the elbow, with a mean follow-up of 57.6 months (30 to 86.4).

Significant reductions in pain and improvement in range of movement and function were recorded. Radiological review revealed two patients with 1 mm lucencies in a single zone, and one patient with 1 mm lucencies in two zones. No components required revision. There were no deep infections, dislocations or mechanical failures. Complications included one intra-operative medial condylar fracture and one post-operative transient ulnar neuropathy, which resolved.

This study demonstrates that the Acclaim prosthesis provides good symptomatic relief and improvement of function in patients with primary osteoarthritis, with low rates of loosening or other complications. This prosthesis can therefore be considered for patients aged ≥ 65 years with primary osteoarthritis of the elbow.

Between 1995 and 2006, five intra-articular osteotomies of the head of the radius were performed in patients with symptomatic healed displaced articular fractures. Pre-operatively, all patients complained of persistent painful clicking on movement. Only patients with mild or no degenerative changes of the radial head and capitellum were considered for osteotomy. The operations were performed at a mean of 8.2 months (4 to 13) after injury and the patients were reviewed at a mean of 5.5 years (15 months to 12 years) after the osteotomy. The average Mayo Elbow Performance Index Score improved significantly from 74 before to 88 after operation, with four patients rated as good or excellent (p < 0.05). The subjective patient satisfaction score was 8.4 on a ten-point scale. All osteotomies healed and there were no complications. In this small series intra-articular osteotomy of the head of the radius was a safe and effective treatment for symptomatic intra-articular malunion without advanced degenerative changes
