Aims. The aim of this study is to report the implant survival and factors associated with revision of total elbow arthroplasty (TEA) using data from the Dutch national registry. Methods. All TEAs recorded in the Dutch national registry between 2014 and 2020 were included. The Kaplan-Meier method was used for survival analysis, and a logistic regression model was used to assess the factors associated with revision. Results. A total of 514 TEAs were included, of which 35 were revised. The five-year implant survival was 91%. Male sex, a higher BMI, and previous surgery to the same elbow showed a statistically significant association with revision (p < 0.036). Of the 35 revised implants, ten (29%) underwent a second revision. Conclusion. This study reports a five-year implant survival of TEA of 91%. Patient factors associated with revision are defined and can be used to optimize informed consent and shared decision-making. There was a high rate of secondary revisions.

Aims. There are concerns regarding complications and longevity of total elbow arthroplasty (TEA) in young patients, and the few previous publications are mainly limited to reports on linked elbow devices. We investigated the clinical outcome of unlinked TEA for patients aged less than 50 years with rheumatoid arthritis (RA). Methods. We retrospectively reviewed the records of 26 elbows of 21 patients with RA who were aged less than 50 years who underwent primary TEA with an unlinked elbow prosthesis. The mean patient age was 46 years (35 to 49), and the mean follow-up period was 13.6 years (6 to 27). Outcome measures included pain, range of motion, Mayo Elbow Performance Score (MEPS), radiological evaluation for radiolucent line and loosening, complications, and revision surgery with or without implant removal. Results. The mean MEPS significantly improved from 47 (15 to 70) points preoperatively to 95 (70 to 100) points at final follow-up (p < 0.001). Complications were noted in six elbows (23%) in six patients, and of these, four with an ulnar neuropathy and one elbow with postoperative traumatic fracture required additional surgeries. There was no revision with implant removal, and there was no radiological evidence of loosening around the components. With any revision surgery as the endpoint, the survival rates up to 25 years were 78.1% (95% confidence interval 52.8 to 90.6) as determined by Kaplan-Meier analysis. Conclusion. The clinical outcome of primary unlinked TEA for young patients with RA was satisfactory and comparable with that for elderly patients. A favourable survival rate without implant removal might support the use of unlinked devices for young patients with this disease entity, with a caution of a relatively high complication rate regarding ulnar neuropathy.

Aims. Arthroplasty is being increasingly used for the management of distal humeral fractures (DHFs) in elderly patients. Arthroplasty options include total elbow arthroplasty (TEA) and hemiarthroplasty (HA); both have unique complications and there is not yet a consensus on which implant is superior. This systematic review asked: in patients aged over 65 years with unreconstructable DHFs, what differences are there in outcomes, as measured by patient-reported outcome measures (PROMs), range of motion (ROM), and complications, between distal humeral HA and TEA?. Methods. A systematic review of the literature was performed via a search of MEDLINE and Embase. Two reviewers extracted data on PROMs, ROM, and complications. PROMs and ROM results were reported descriptively and a meta-analysis of complications was conducted. Quality of methodology was assessed using Wylde’s non-summative four-point system. The study was registered with PROSPERO (CRD42021228329). Results. A total of 29 studies met the inclusion and exclusion criteria. The mean Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) score was 19.6 (SD 7.5) for HA and 38 (SD 11.9) for TEA and the mean abbreviated version of DASH was 17.2 (SD 13.2) for HA and 24.9 (SD 4.8) for TEA. The Mayo Elbow Performance Score was the most commonly reported PROM across included studies, with a mean of 87 (SD 5.3) in HA and 88.3 (SD 5) in TEA. High complication rates were seen in both HA (22% (95% confidence interval (CI) 5 to 44)) and TEA (21% (95% CI 13 to 30), but no statistically significant difference identified. Conclusion. This systematic review has indicated PROMs and ROM mostly favouring HA, but with a similarly high complication rate in the two procedures. However, due to the small sample size and heterogeneity between studies, strength of evidence for these findings is low. We propose further research in the form of a national randomized controlled trial. Cite this article: Bone Joint J 2022;104-B(5):559–566

Aims. The aims of this study were to validate the outcome of total elbow arthroplasty (TEA) in patients with rheumatoid arthritis (RA), and to identify factors that affect the outcome. Methods. We searched PubMed, MEDLINE, Cochrane Reviews, and Embase from between January 2003 and March 2019. The primary aim was to determine the implant failure rate, the mode of failure, and risk factors predisposing to failure. A secondary aim was to identify the overall complication rate, associated risk factors, and clinical performance. A meta-regression analysis was completed to identify the association between each parameter with the outcome. Results. A total of 38 studies including 2,118 TEAs were included in the study. The mean follow-up was 80.9 months (8.2 to 156). The implant failure and complication rates were 16.1% (95% confidence interval (CI) 0.128 to 0.200) and 24.5% (95% CI 0.203 to 0.293), respectively. Aseptic loosening was the most common mode of failure (9.5%; 95% CI 0.071 to 0.124). The mean postoperative ranges of motion (ROMs) were: flexion 131.5° (124.2° to 138.8°), extension 29.3° (26.8° to 31.9°), pronation 74.0° (67.8° to 80.2°), and supination 72.5° (69.5° to 75.5°), and the mean postoperative Mayo Elbow Performance Score (MEPS) was 89.3 (95% CI 86.9 to 91.6). The meta-regression analysis identified that younger patients and implants with an unlinked design correlated with higher failure rates. Younger patients were associated with increased complications, while female patients and an unlinked prosthesis were associated with aseptic loosening. Conclusion. TEA continues to provide satisfactory results for patients with RA. However, it is associated with a substantially higher implant failure and complication rates compared with hip and knee arthroplasties. The patient’s age, sex, and whether cemented fixation and unlinked prosthesis were used can influence the outcome. Level of Evidence: Therapeutic Level IV.

Aims. The aim of this meta-analysis was to compare the outcome of total elbow arthroplasty (TEA) undertaken for rheumatoid arthritis (RA) with TEA performed for post-traumatic conditions with regard to implant failure, functional outcome, and perioperative complications. Materials and Methods. We completed a comprehensive literature search on PubMed, Web of Science, Embase, and the Cochrane Library and conducted a systematic review and meta-analysis. Nine cohort studies investigated the outcome of TEA between RA and post-traumatic conditions. The preferred reporting items for systematic reviews and meta-analysis (Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)) guidelines and Newcastle-Ottawa scale were applied to assess the quality of the included studies. We assessed three major outcome domains: implant failures (including aseptic loosening, septic loosening, bushing wear, axle failure, component disassembly, or component fracture); functional outcomes (including arc of range of movement, Mayo Elbow Performance Score (MEPS), and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire), and perioperative complications (including deep infection, intraoperative fracture, postoperative fracture, and ulnar neuropathy). Results. This study included a total of 679 TEAs for RA (n = 482) or post-traumatic conditions (n = 197). After exclusion, all of the TEAs included in this meta-analysis were cemented with linked components. Our analysis demonstrated that the RA group was associated with a higher risk of septic loosening after TEA (odds ratio (OR) 3.96, 95% confidence interval (CI) 1.11 to 14.12), while there was an increased risk of bushing wear, axle failure, component disassembly, or component fracture in the post-traumatic group (OR 4.72, 95% CI 2.37 to 9.35). A higher MEPS (standardized mean difference 0.634, 95% CI 0.379 to 0.890) was found in the RA group. There were no significant differences in arc of range of movement, DASH questionnaire, and risk of aseptic loosening, deep infection, perioperative fracture, or ulnar neuropathy. Conclusion. The aetiology of TEA surgery appears to have an impact on the outcome in terms of specific modes of implant failures. RA patients might have a better functional outcome after TEA surgery.

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).

To prevent insufficiency of the triceps after total elbow arthroplasty, we have, since 2008, used a triceps-sparing ulnar approach. This study evaluates the clinical results and post-operative alignment of the prosthesis using this approach.

We reviewed 25 elbows in 23 patients. There were five men and 18 women with a mean age of 69 years (54 to 83). There were 18 elbows with rheumatoid arthritis, six with a fracture or pseudoarthrosis and one elbow with osteoarthritis.

Post-operative complications included one intra-operative fracture, one elbow with heterotopic ossification, one transient ulnar nerve palsy, and one elbow with skin necrosis, but no elbow was affected by insufficiency of the triceps.

Patients were followed for a mean of 42 months (24 to 77). The mean post-operative Japanese Orthopaedic Association Elbow Score was 90.8 (51 to 100) and the mean Mayo Elbow Performance score 93.8 (65 to 100). The mean post-operative flexion/extension of the elbow was 135°/-8°. The Manual Muscle Testing score of the triceps was 5 in 23 elbows and 2 in two elbows (one patient). The mean alignment of the implants examined by 3D-CT was 2.8° pronation (standard deviation (sd) 5.5), 0.3° valgus (sd 2.7), and 0.7° extension (sd 3.2) for the humeral component, and 9.3° pronation (sd 9.7), 0.3° valgus (sd 4.0), and 8.6° extension (sd 3.1) for the ulnar component. There was no radiolucent line or loosening of the implants on the final radiographs.

The triceps-sparing ulnar approach allows satisfactory alignment of the implants, is effective in preventing post-operative triceps insufficiency, and gives satisfactory short-term results.

Aims. The aims of this study were to identify and evaluate the current literature examining the prognostic factors which are associated with failure of total elbow arthroplasty (TEA). Methods. Electronic literature searches were conducted using MEDLINE, Embase, PubMed, and Cochrane. All studies reporting prognostic estimates for factors associated with the revision of a primary TEA were included. The risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool, and the quality of evidence was assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. Due to low quality of the evidence and the heterogeneous nature of the studies, a narrative synthesis was used. Results. A total of 19 studies met the inclusion criteria, investigating 28 possible prognostic factors. Most QUIPS domains (84%) were rated as moderate to high risk of bias. The quality of the evidence was low or very low for all prognostic factors. In low-quality evidence, prognostic factors with consistent associations with failure of TEA in more than one study were: the sequelae of trauma leading to TEA, either independently or combined with acute trauma, and male sex. Several other studies investigating sex reported no association. The evidence for other factors was of very low quality and mostly involved exploratory studies. Conclusion. The current evidence investigating the prognostic factors associated with failure of TEA is of low or very low quality, and studies generally have a moderate to high risk of bias. Prognostic factors are subject to uncertainty, should be interpreted with caution, and are of little clinical value. Higher-quality evidence is required to determine robust prognostic factors for failure of TEA. Cite this article: Bone Joint Res 2024;13(5):201–213

Open debridement and Outerbridge and Kashiwagi debridement arthroplasty (OK procedure) are common surgical treatments for elbow arthritis. However, the literature contains little information on the long-term survivorship of these procedures. The purpose of this study was to determine the survivorship after elbow debridement techniques until conversion to total elbow arthroplasty and revision surgery. We performed a retrospective chart review of patients who underwent open elbow surgical debridement (open debridement, OK procedure) between 2000 and 2015. Patients were diagnosed with primary elbow osteoarthritis, post-traumatic arthritis, or inflammatory arthritis. A total of 320 patients had primary surgery including open debridement (n=142) and OK procedure (n=178), and of these 33 patients required a secondary revision surgery (open debridement, n=14 and OK procedure, n=19). The average follow-up time was 11.5 years (5.5 - 21.5 years). Survivorship was analyzed with Kaplan-Meier curves and Log Rank test. A Cox proportional hazards model was used assess the likelihood of conversion to total elbow arthroplasty or revision surgery while adjusting for covariates (age, gender, diagnosis). Significance was set p<0.05. Kaplan-Meier survival curves showed open debridement was 100.00% at 1 year, 99.25% at 5 years, and 98.49% at 10 years and for OK procedure 100.00% at 1 year, 98.80% at 5 years, 97.97% at 10 years (p=0.87) for conversion to total elbow arthroplasty. There was no difference in survivorship between procedures after adjusting for significant covariates with the cox proportional hazard model. The rate of revision for open debridement and OK procedure was similar at 11.31% rand 11.48% after 10 years respectively. There were higher rates of revision surgery in patients with open debridement (hazard ratio, 4.84 CI 1.29 – 18.17, p = 0.019) compared to OK procedure after adjusting for covariates. We also performed a stratified analysis with radiographic severity as an effect modifier and showed grade 3 arthritis did better with the OK procedure compared to open debridement for survivorship until revision surgery (p=0.05). However, this difference was not found for grade 1 or grade 2 arthritis. This may suggest that performing the OK procedure for more severe grade 3 arthritis could decrease reoperation rates. Further investigations are needed to better understand the indications for each surgical technique. This study is the largest cohort of open debridement and OK procedure with long term follow-up. We showed that open elbow debridement and the OK procedure have excellent survivorship until conversion to total elbow arthroplasty and are viable options in the treatment of primary elbow osteoarthritis and post traumatic cases. The OK procedure also has lower rates of revision surgery than open debridement, especially with more severe radiographic arthritis

This study reports our experience with total elbow replacement for fused elbows. Between 1982 and 2004, 13 patients with spontaneously ankylosed elbows were treated with a linked semi-constrained non-custom total elbow implant. The mean age at operation was 54 years (24 to 80). The stiffness was a result of trauma in ten elbows, juvenile rheumatoid arthritis in one, and rheumatoid arthritis in two. The patients were followed for a mean of 12 years (2 to 26) and were evaluated clinically using the Mayo Elbow Performance Score, as well as radiologically. A mean arc from 37° of extension to 118° of flexion was achieved. Outcomes were good or excellent for seven elbows at final review. Ten patients felt better or much better after total elbow replacement. However, there was a high complication rate and re-operation was required in over half of patients. Two developed peri-operative soft-tissue breakdown requiring debridement. A muscle flap with skin grafting was used for soft-tissue cover in one. Revision was undertaken in one elbow following fracture of the ulnar component. Three patients developed a deep infection. Three elbows were manipulated under anaesthesia for post-operative stiffness. Prophylactic measures for heterotopic ossification were unsuccessful. Total elbow replacement for the ankylosed elbow should be performed with caution. However, the outcome can be reliable in the long term and have a markedly positive impact on patient function and satisfaction. The high potential for complications must be considered. We consider total elbow replacement to be an acceptable procedure in selected patients with reasonable expectations

Between 1993 and 2002, 58 GSB III total elbow replacements were implanted in 45 patients with rheumatoid arthritis by the same surgeon. At the most recent follow-up, five patients had died (five elbows) and six (nine elbows) had been lost to follow-up, leaving 44 total elbow replacements in 34 patients available for clinical and radiological review at a mean follow-up of 74 months (25 to 143). There were 26 women and eight men with a mean age at operation of 55.7 years (24 to 77). At the latest follow-up, 31 excellent (70%), six good (14%), three fair (7%) and four poor (9%) results were noted according to the Mayo elbow performance score. Five humeral (11%) and one ulnar (2%) component were loose according to radiological criteria (type III or type IV). Of the 44 prostheses, two (5%) had been revised, one for type-IV humeral loosening after follow-up for ten years and one for fracture of the ulnar component. Seven elbows had post-operative dysfunction of the ulnar nerve, which was transient in five and permanent in two. Despite an increased incidence of loosening with time, the GSB III prosthesis has given favourable mid-term results in patients with rheumatoid arthritis

Between September 1993 and September 1996, we performed 34 Kudo 5 total elbow replacements in 31 rheumatoid patients. All 22 surviving patients were reviewed at a mean of 11.9 years (10 to 14). Their mean age was 56 years (37 to 78) at the time of operation. All had Larsen grade IV or V rheumatoid changes on X-ray. Nine (three bilateral replacements and six unilateral) had died from unrelated causes. One who had died before ten years underwent revision for dislocation. Of the 22 total elbow replacements reviewed six had required revision, four for aseptic loosening (one humeral and three ulnar) and two for infection. Post-operatively, one patient had neuropraxia of the ulnar nerve and one of the radial nerve. Two patients had valgus tilting of the ulnar component. With revision as the endpoint, the mean survival time for the prosthesis was 11.3 years (95% confidence interval (10 to 13) and the estimated survival of the prosthesis at 12 years according to Kaplan-Meier survival analysis was 74% (95% confidence interval 0.53 to 0.91). Of the 16 surviving implants, ten were free from pain, four had mild pain and two moderate. The mean arc of flexion/extension of the elbow was 106° (65° to 130°) with pronation/supination of 90° (30° to 150°) with the joint at 90° of flexion. The mean Mayo elbow performance score was 82 (60 to 100) with five excellent, ten good and one fair result. Good long-term results can be expected using the Kudo 5 total elbow replacement in patients with rheumatoid disease, with a low incidence of loosening of the components

Ulnar neuropathy presents as a complication in 5% to 10% of total elbow replacements, but subsequent ulnar neurolysis is rarely performed. Little information is available on the surgical management of persistent ulnar neuropathy after elbow replacement. We describe our experience with the surgical management of this problem. Of 1607 total elbow replacements performed at our institution between January 1969 and December 2004, eight patients (0.5%) had a further operation for persistent or progressive ulnar neuropathy. At a mean follow-up of 9.2 years (3.1 to 21.7) six were clinically improved and satisfied with their outcome, although, only four had complete recovery. When transposition was performed on a previously untransposed nerve the rate of recovery was 75%, but this was reduced to 25% if the nerve had been transposed at the time of the replacement

Total Elbow Replacements are indicated for pain and disability in patients with rheumatoid and osteoarthritis of the elbow. The quality of the cementation has been specifically studied and shown to be directly related to the clinical outcome and implant survival. Aim. The aim of our study is to radiologically assess and grade the cementation around the components following total elbow replacement (GSB 3 or Coonrad Morrey) in two groups of patients. Materials and methods. Group I underwent total elbow replacement using Heraeus cement gun with medium palacos viscosity cement and group 2 using Zimmer cement gun with simplex medium viscosity cement. Average age in Group 1 was 72.3 (range 67–88 yrs) and group 2 was 69 years (range 52–87 yrs). 3 Coonrad Morrey and 13 GSB 3 total elbow replacement were used in Group 1 and 2 Coonrad Morrey and 14 GSB 3 in group 2. The primary indication for surgery was osteoarthritis, rheumatoid arthritis, post traumatic arthritis and seronegative arthritis in both groups. The cementation was assessed radiologically using three grading system (Morrey, Gerber & Bristol). Results. In Group I (Heraeus) 14 had adequete cementation in both AP and lateral radiographs, 1 humeral and 1 ulna components on AP radiograph revealed marginal cementing. In Group 2 (Zimmer) 11 had adequete cementation in both AP and lateral radiographs, 1 humeral and 1 ulna on AP and 1 humerus and 3 ulna on lateral radiograph were 4 marginal. Conclusion. Precise application of cement during total elbow arthroplasty is an important factor in achieving good implant fixation. To achieve this, a proper ergonomic design of the cement gun is mandatory. From our study we conclude that there was a difference in quality of cementation between the two groups

We reviewed 20 patients who had undergone a Coonrad-Morrey total elbow arthroplasty after resection of a primary or metastatic tumour from the elbow or distal humerus between 1980 and 2002. Eighteen patients underwent reconstruction for palliative treatment with restoration of function after intralesional surgery and two after excision of a primary bone tumour. The mean follow-up was 30 months (1 to 192). Five patients (25%) were alive at the final follow-up; 14 (70%) had died of their disease and one of unrelated causes. Local control was achieved in 15 patients (75%). The mean Mayo Elbow Performance Score improved from 22 (5 to 45) to 75 points (55 to 95). Four reconstructions (20%) failed and required revision. Seven patients (35%) had early complications, the most frequent being nerve injury (25%). There were no infections or wound complications although 18 patients (90%) had radiotherapy, chemotherapy or both. The Coonrad-Morrey total elbow arthroplasty provides good relief from pain and a good functional outcome after resection of tumours of the elbow. The rates of complications involving local recurrence of tumour (25%) and nerve injury (25%) are of concern

Aim. Infections after total elbow arthroplasty are more frequent than after other joint arthroplasties. Therapeutic management varies depending of the patient status, the time of diagnosis of the infection, the status of the implant as well as the remaining bone stock around the implants. Method. Between 1997 and 2017, 180 total elbow arthroplasties were performed in our department. Eleven (6%) sustained a deep infection and were revised. Infection occurred after prosthesis of first intention in 4 and after a revision procedure in 7. Etiologies were: rheumatoid arthritis in 6, trauma sequela in 4 and osteosarcoma in 1. There were 7 women and 4 men of 59 years on average (22–87). Delay between the prosthesis and the diagnosis of infection was 66 months (0.5–300). The infection was stated as acute (<3week) in one, subacute (between 3 week and 3 months) in 1, and chronic (>3 months) in 9. Isolated bacteria were: Staphylococcus (10), Streptococcus (1), P. acnes (1), and Proteus mirabilis (1). Infection were poly microbial in 2 cases. A simple lavage with debridement was performed in 3 cases (Group 1), a 2-stage revision in 4 (Group 2), and a definitive removal of the prosthesis in 4 (Group 3). Adapted antibiotics were prescribed for all patients during at least 6 weeks. Results. All patients were reviewed with 59 months average follow-up. Eight patients were cured of their infection thanks to the initial therapeutic strategy. For 2 patients of Group 2, infection reccurrency required a new surgical procedure with one simple lavage/debridement for one, and 3 lavage/debridement for the other making it possible to cure the infection. For one patient of Group 1, a failure of lavage/debridement required removal of the implants. The MEPS reached 72 points: 67 points for patients of Group 1, 76 points for patients of Group 2, and 74 points for patients of Group 3. Complication rate was 36% (4): 2 ulnar nerve impairment with dysesthesia, one radial nerve palsy, and one humeral stem loosening. Conclusions. An adapted therapeutic strategy can allow suppression of the responsible bacteria after infection of total elbow arthroplasty. Sometimes, several procedures are necessary to obtain the cure. Better functional results were obtained when the prosthesis could be retained or replaced, but satisfactory results could also be obtained after resection arthroplasty when the humeral columns have been preserved to stabilize the joint

Aim. The primary aim of this retrospective study was to identify the incidence of heterotopic ossification (HO) following elective and trauma elbow arthroplasty. The secondary aim was to determine clinical outcomes with respect to the formation of heterotopic ossification. Patients and Methods. A total of 55 total elbow arthroplasties (TEAs) (52 patients) performed between June 2007 and December 2015 were eligible for inclusion in the study (29 TEAs for primary elective arthroplasty and 26 TEAs for trauma). At review, 15 patients (17 total elbow arthroplasties) had died from unrelated causes. There were 14 men and 38 women with a mean age of 70 years (42 to 90). The median clinical follow-up was 3.6 years (1.2 to 6) and the median radiological follow-up was 3.1 years (0.5 to 7.5). Results. The overall incidence of HO was 84% (46/55). This was higher in the trauma group (96%, 25/26) compared with the elective arthroplasty group (72%, 21/29) (p = 0.027, Fisher’s exact test). Patients in the trauma group had HO of higher Brooker class. The presence of HO did not significantly affect elbow range of movement within the trauma or elective groups (elective arthroplasty, Mann–Whitney U test, p = 0.070; trauma arthroplasty, p = 0.370, Mann–Whitney U test). Conclusion. HO after total elbow arthroplasty is seen more commonly than previously reported. We have reported a significantly higher rate of HO in TEAs performed for trauma than those performed electively. Cite this article: Bone Joint J 2018;100-B:767–71

Aims: To review the results from a series of GSB III total elbow arthroplasties performed at an independent centre. Between 1996 and 2004 the senior author performed 58 total elbow arthroplasties in 44 patients (10 males, 34 females) using the GSB III implant. These were reviewed and the outcome assessed through the use of a patient-answered questionnaire and clinical and radiological review. Mean age was 65 (49 to 84 years). Indications for surgery included rheumatoid arthritis (46 elbows) and post-traumatic osteoarthritis (11 elbows). Mean F/up was 4.1 years (0.8 to 8.5 years). 4 patients had died (6 elbows) and 4 patients (4 elbows) were unavailable for review. 2 of the implants had been revised (1x aseptic loosening, 1x deep infection), leaving a total of 46 elbows available for review. The survival rate at a mean of 4 years was 98% with aseptic loosening as the endpoint. Complications included 1 case of intraoperative fracture and 1 persistent ulnar neuritis. Overall patient satisfaction was high. The mean Mayo Elbow Performance Score was 83 out of 100 (range, 34 to 100) and mean Liverpool Elbow Score was 8 out of 10 (range, 1 to 10). Conclusion: Previous studies of outcome following total elbow arthroplasty using the GSB III elbow prosthesis at independent centres have shown satisfactory results, but have looked at small groups of patients. Our results offer more robust data to show that the medium term outcome following total elbow arthroplasty using the GSB III prosthesis is satisfactory

Aims: To review the results from a series of GSB III total elbow arthroplasties performed at an independent centre. Between 1996 and 2004, the senior author performed 58 total elbow arthroplasties in 44 patients (10 males, 34 females) using the GSB III implant. These were reviewed and the outcome assessed through the use of a patient-answered questionnaire and clinical and radiological review. Mean age was 65 (49 to 84 years). Indications for surgery included rheumatoid arthritis (46 elbows) and post-traumatic osteoarthritis (11 elbows). Mean F/up was 4.1 years (0.8 to 8.5 years). Four patients had died (six elbows) and four patients (four elbows) were unavailable for review. Two of the implants had been revised (1x aseptic loosening, 1x deep infection), leaving a total of 46 elbows available for review. The survival rate at a mean of four years was 98% with aseptic loosening as the endpoint. Complications included one case of intraoperative fracture and one persistent ulnar neuritis. Overall patient satisfaction was high. The mean Mayo Elbow Performance Score was 83 out of 100 (range, 34 to 100) and mean Liverpool Elbow Score was 8 out of 10 (range, 1 to 10). Conclusion: Previous studies of outcome following total elbow arthroplasty using the GSB III elbow prosthesis at independent centres have shown satisfactory results, but have looked at small groups of patients. Our results offer more robust data to show that the medium term outcome following total elbow arthroplasty using the GSB III prosthesis is satisfactory

Reconstruction of deficient bone stock during total elbow arthroplasty in rheumatoid arthritis represents a challenge for the surgeon. Fracture and osteolysis of the olecranon process is a very rare condition in rheumatoid arthritis. The consequence of a deficient olecranon is an instable and painful elbow. We report a case of successful olecranon reconstruction with bone graft associated to total elbow arthroplasty with a 8 years follow up and discuss surgical aspects. This case concerns a 44 years old woman with a very severe rheumatoid arthritis. She complains of pain and instability of her right elbow. X-rays show fracture and major osteolysis of the olecranon process with only some persistent bone at the insertion of the triceps tendon. The humeral condyles were subluxated posteriorly. We performed a total elbow replacement with a GSB3 implant and reconstruction of the olecranon with two cancellous iliac bone strut fixed by 2.7 diameter screws to the proximal ulna. The triceps tendon with remnant olecranon bone chips was secured to the bone graft by tension band wiring. Postoperatively, the elbow was immobilized for 3 weeks. With a follow up of more than 8 years the elbow is pain free with excellent function. The active range of motion of flexion – extension is 140° / −20°. The elbow is stable and triceps function is very satisfying authorizing the use of crutches. X-rays show good bony integration of the reconstructed olecranon process and no signs of loosening of the GSB3 implant. The literature concerning olecranon reconstruction during total elbow arthroplasty in rheumatoid patients is very poor. Kamineni and Morrey reported on one case of olecranon reconstruction with strut allograft in revision total elbow arthroplasty with an unsatisfying result. Their fixation technique was different. We prefer an autograft whenever it is possible and we recommend our fixation technique using screws and tension band wiring

The purpose of this study was to assess the long-term results (more than ten years) of two types of cemented ulnar component with type-5 Kudo total elbow arthroplasty in a consecutive series of 56 patients (60 elbows) with rheumatoid arthritis, and to compare the results in elbows above and below a Larsen grade IV. There was no radiolucency around the humeral component. Patients in whom a metal-backed ulnar component and a porous-coated stem were used had better clinical results and significantly less progression of radiolucent line formation around the ulnar component. They also had a significantly better long-term survival than patients with an all-polyethylene ulnar component. The clinical results of arthroplasty using all-polyethylene ulnar components were inferior, regardless of the degree of joint destruction. We conclude that the type-5 Kudo total elbow arthroplasty with cementless fixation of the porous-coated humeral component and cemented fixation of a metal-backed ulnar component is acceptable and well-tolerated by rheumatoid patients

Heterotopic Ossification (HO) is a known complication that can arise after total elbow arthroplasty (TEA). In most cases it is asymptomatic, however, in some patients it can limit range of motion and lead to poor outcomes. The objective of this review was to assess and report incidence, risk factors, prophylaxis, and management of HO after TEA. A systematic search was conducted using MEDLINE, EMBASE, and PubMed to retrieve all relevant studies evaluating occurrence of HO after TEA. The search was performed in duplicate and a quality assessment was performed of all included studies. A total of 1907 studies were retrieved of which 45 studies were included involving 2256 TEA patients. HO was radiographically present in 10% of patients and was symptomatic in 3%. Less than 1% of patients went on to surgical excision of HO, with outcomes following surgery reported as good or excellent as assessed by range of motion and Mayo Elbow Performance Scores (MEPS). TEA due to ankylosis, primary osteoarthritis, and posttraumatic arthritis are more likely to develop symptomatic HO. HO is an uncommon complication following TEA with the majority of patients developing HO being asymptomatic and requiring no surgical management. Routine HO prophylaxis for TEA is not supported by the literature. The effectiveness of prophylaxis in high risk patients is uncertain and future studies are required to clarify its usefulness. The strength of these conclusions are limited by inconsistent reporting in the available literature

The purpose of this study is to report our experience with revision of total elbow arthroplasty by exchange cementation. Between 1982 and 2004 at our institution, forty six elbows were treated with exchange cementation of a total elbow arthroplasty into the existing cement mantle or debrided bone interface, without the use of an osteotomy, bone graft or prosthetic augmentation. Indications for the procedure were aseptic loosening (17), second stage after septic loosening (14), instability (7), prosthetic fracture (4), periprosthetic fracture (2), failed hemiarthroplasty (1) and ulnar component wear (1). Both components were exchanged in 18 elbows, the humerus alone in 25 and the ulna in 3. Mean follow up was 90.5 months (10 to 266 months);18 patients had died with the prosthesis in situ. Complications were noted in 22 elbows; periprosthetic fracture of ulna (6) and humerus (2), humeral component fracture (1), aseptic loosening (4), non-union (1), heterotrophic ossification (2), soft tissue contracture (2) and soft tissue failure (2), delayed wound healing (1) and bushing failure (1). Reoperation was required in 10 elbows for revision of both components (2), ulna (3), humerus (1), bushing revision (2), soft tissue debridement (1) and soft tissue repair (1). There were no septic recurrences in previously infected elbows; however the reoperation rate in this group was 29% versus 19% after re-cementation for other causes. Revision of total elbow arthroplasty by exchange cementation is a reasonable treatment for those elbows with adequate bone stock for secure prosthetic fixation; however careful consideration should be given to augmentation of the ulna due to the high rate of periprosthetic fracture in this series. Re-cementation following débridement for infection is effective despite having a higher rate of revision operation compared to re-cementation in the aseptic elbow

We present the early results of 36 primary total elbow arthroplasties using the Acclaim prosthesis. The Acclaim prosthesis was used in 46 primary total elbow arthroplasties between July 2000 and August 2002. All operations were performed or directly supervised by the two senior authors (IAT and JKS). There were 32 females and 14 males. The mean age at surgery was 64 years (range, 34–93). The underlying pathology was rheumatoid arthritis in 39, osteoarthritis in five and post-traumatic arthritis in two. The early results of 36 cases are presented at a minimum follow-up of two years. Patients were assessed using the American Shoulder and Elbow Surgeons patient self assessment form and the range of movement of the elbow measured. The Wrightington method was used for radiographic analysis of lucencies. There was good relief of pain and range of movement improved. The mean preoperative pain score was 8.1 and decreased to 2.1 at latest follow up. The mean disability score increased from 34.2 to 66.1. The mean overall satisfaction rating following surgery was 9.3 on a visual analogue scale from zero to ten. The mean range of flexion increased from 83. o. to105. o. The mean flexion gain was just over 10. o. and the mean extension gain was just over 12. o. There were 11 cases of intraoperative fracture of the humeral condyle. One of these fractures failed to unite and required revision to a linked prosthesis because of persistent instability. There was one case of deep infection. There were three cases of ulnar neuropathy, one of which resolved. There was no evidence of loosening. The Acclaim total elbow arthroplasty gives good symptomatic relief and improvement in function according to the American Shoulder and Elbow Surgeons patient self assessment form. These early results are encouraging but the frequency of intra-operative fractures is of some concern

We present the outcome of 47 Souter-Strathclyde replacements of the elbow with a mean follow-up of 82 months (12 to 129). The clinical results were assessed using a condition-specific outcome measure. The mean total score (maximum 100) before the operation was 47.21 and improved to 79.92 (p < 0.001). The mean pain score (maximum 50) improved from 21.41 to 46.70 (p < 0.001) and the mean functional component of the score (maximum 30) from 11.19 to 18.65 (p < 0.001). There was negligible change in the score for the range of movement although a significant improvement in mean flexion from 124° to 136° was noted (p < 0.001). Revision surgery was required in four patients, for dislocation, wound dehiscence and early infection in one, late infection in two and aseptic loosening in one. The cumulative survival was 75% at nine years for all causes of failure and 97% at ten years for aseptic loosening alone. Our study demonstrates the value of the Souter-Strathclyde total elbow arthroplasty in providing relief from pain and functional improvement in rheumatoid patients

There have been few reports in the literature of total elbow arthroplasty extending beyond 10 to 15 years. We reviewed 40 patients (41 elbows) with a mean age of 56 years (19 to 83) who had undergone a Coonrad/Coonrad-Morrey elbow arthroplasty by one surgeon for various diagnoses between 1974 and 1994. Surgical selection excluded patients with previous elbow infection or who refused to accept a sedentary level of elbow activity postoperatively. Objective data were collected from charts, radiographs, clinical photographs and supplemented by the referring orthopaedic surgeons’ records and radiographs if health or distance prevented a patient from returning for final review. Subjective outcome was defined by patient satisfaction. Of the 41 elbows, 21 were functional between 10 and 14 years after operation, ten between 15 and 19 years and ten between 20 and 31 years. There were 14 complications and 13 revisions, but no cases of acute infection, or permanent removal of any implant

Aim: To study the role of total elbow replacement in the management of distal humeral fractures in elderly patients. Patients and methods: Between 1995 and 2003, 25 consecutive patients with fractures of the distal humerus were treated by primary total elbow replacement using the Coonrad-Morrey prosthesis. All surgeries were performed by one of the senior authors in two centers in South Wales. There were 18 females and 7 males and none of them had inflammatory or degenerative arthritis of the elbow. The mean age at the time of injury was 78 years (68–84). According to the AO classification, 16 patients had suffered a C3 injury, five type B3 and three type A3. One fracture was unclassified. The mean time to follow-up was 4 years (1–9 years). Results: At follow-up 19 patients (76%) reported no pain, five (20%) had mild pain with activity and one had mild pain at rest. The mean flexion arc was 28 degrees to 105 degrees. The mean supination was 69 degrees (50–90) and pronation 70 degrees (50–80). No elbow was unstable. Mean Mayo elbow performance score was 71.5(25–100). Four patients (16%) developed ulnar neuropraxia following surgery that improved with time, 2 patients developed superficial wound infection (staphylococcus aureus), which was treated with antibiotics only. None of the above elbows required revision to date. Radiological evaluation revealed only one patient with a radio-lucent line at the cement -bone interface. It was between 1 and 2mm in length, was present on the initial postoperative radiograph and was non-progressive at the time of follow-up. Conclusion: Primary total elbow arthroplasty is an acceptable option for the management of comminuted fractures of the distal humerus in elderly patients when the configuration of the fracture and the quality of the bone make reconstruction difficult

Although it is generally accepted that revision total elbow replacement may be necessary for loosening, instability, peri-prosthetic fracture and infection there is less agreement as to whether surgery should be performed as a one or two stage procedure. This can be of vital importance since the soft tissues around the elbow are often relatively poor making a single operation desirable. However, a one stage procedure in the presence of undetected low grade infection will result in joint failure with early loosening. In our unit we have found the use of a preliminary aspiration/drill biopsy prior to revision surgery helpful in evaluating whether a one or two stage procedure should be performed. Over an 8 year period 18 revision total elbow replacements have been undertaken. 9 patients were revised for aseptic loosening, 4 for proven infection, 3 for instability of an unlinked implant and 2 for peri-prosthetic fracture. With this experience we have devised the following management plan: Early instability of an unlinked implant is due to either poor implant positioning or soft tissue balancing and is suitable for a one stage revision without the need for aspiration/drill biopsy. Late instability is due to implant wear or low grade infection. In this situation we regard an aspiration/drill biopsy as necessary. A negative result allows a one stage revision whereas a positive aspiration indicates the need for a two stage revision. In a peri-prosthetic fracture if the bone cement mantle is intact a one stage revision without aspiration/ drill biopsy can be performed. If however, there is bone cement lucency we would advise an aspiration/ drill biopsy. We have found the aspiration/drill biopsy helpful prior to revision total elbow replacement and we have used it to guide us as to whether a one or two stage procedure should be performed

We assessed the long-term results of 58 Souter-Strathclyde total elbow replacements in 49 patients with rheumatoid arthritis. The mean length of follow-up was 9.5 years (0.7 to 16.7). The mean pre-operative Mayo Elbow Performance Score was 30 (15 to 80) and at final follow-up was 82 (60 to 95). A total of 13 elbows (22.4%) were revised, ten (17.2%) for aseptic loosening, one (1.7%) for instability, one (1.7%) for secondary loosening after fracture, and one elbow (1.7%) was removed because of deep infection. The Kaplan-Meier survival rate was 70% and 53% at ten and 16 years, respectively. Failure of the ulnar component was found to be the main problem in relation to the loosening. Anterior transposition of the ulnar nerve had no influence on ulnar nerve paresthaesiae in these patients

We reviewed 25 patients with rheumatoid arthritis who had failure of 26 primary total elbow arthroplasties causing pain and loss of function. Most revision cases required special custom implants to treat varying bone loss and soft-tissue disruption. Assessment showed satisfactory functional results in the patients treated by revision at a mean follow-up period of 35 months. Our review suggests that revision surgery produces short- to medium-term painfree function, and is the treatment of choice for a failed total elbow arthroplasty in the absence of infection

The aim of this study was to assess the long-term results of the Kudo type-5 total elbow prosthesis and compare the results of two types of cemented ulnar components. The Kudo type-5 unlinked total elbow prosthesis (Biomet UK Ltd, Bridgend Wales) was developed in 1993. The stem of humeral component is porous-coated with a plasma spray of titanium alloy for cementless use. The ulnar component may be metal-backed with a porous-coated stem or polyethylene alone; the latter designed mainly for cement use. A metal-backed type without a porous-coated stem designed for cement use also came into being after 2003. Between 1993 and 2010, the Kudo type-5 total elbow arthroplasty was performed on 364 elbows in 274 consecutive patients with rheumatoid arthritis. The mean age of the patients at the time of the operation was 60.7 (27–86) years. Twenty elbows had Larsen grade III, 224 had grade IV, and 120 had grade V changes pre-operatively. Before the operation, 346 elbows had severe or moderate pain, 95 had gross valgus-varus instability. Clinical symptoms and revision rates were assessed 4 to 20 years (mean, 9 years) postoperatively. The mean Mayo elbow performance scores were all poor except for three initially (mean overall score, 39.5 points). The overall score had improved substantially both at the early follow-up (1 to 3 years after the operation) and the latest follow-up (4 to 20 years after the operation), with 89.5 and 84.7 points, respectively. At the latest follow-up the overall result was excellent for 185 elbows, good for 103, fair for 11 and poor for 30, with almost complete relief from pain for 298. The arc of movement had increased from a mean of 85.7 °pre-operatively to 95.1 ° post-operatively, and to 98.1 °at the latest follow-up. Spot welds around the humeral stem suggesting solid osseous integration were often seen in the elbows with cementless fixation of the porous humeral stem. At the latest follow-up, implants were removed due to infection in 3 elbows. Twenty-five elbows required ulnar component revision due to loosening of the all-polyethylene component. Two elbows required ulnar component revision due to loosening of the metal-backed component. Seven elbows required humeral component revision due to loosening of the humeral components. One elbow required revision due to dislocation. A survival analysis with revision or removal of one or both components as the end point was performed according to the Kaplan and Meier method. The overall survival rate of the prosthesis was 75.2% at 19 years. The survival of 87.0% in the metal-backed group was higher than the 74.3% in the all-polyethylene group. Loosening of the all-polyethylene ulnar component was the main reason for deterioration in the long-term outcome. We conclude that the long-term results of the Kudo type-5 total elbow arthroplasty is acceptable and cemented fixation of metal-backed ulnar component had better long-term survival than the all-polyethylene component

Between 1982 and 1997, 403 consecutive patients (522 elbows) with rheumatoid arthritis underwent Souter-Strathclyde total elbow replacement. By the end of 2007, there had been 66 revisions for aseptic loosening in 60 patients. The mean time of follow-up was 10.6 years (0 to 25) The survival rates at five-, ten, 15 and 19 years were 96% (95%, confidence interval (CI) 95 to 98), 89% (95% CI 86 to 92), 83% (95% CI 78 to 87), and 77% (95% CI 69 to 85), respectively. The small and medium-sized short-stemmed primary humeral components had a 5.6-fold and 3.6-fold risk of revision for aseptic loosening respectively, compared to the medium-sized long-stemmed component. The small and medium-sized all-polyethylene ulnar components had respectively a 28.2-fold and 8.4-fold risk of revision for aseptic loosening, compared to the metal-backed ulnar components. The use of retentive ulnar components was not associated with an increased risk of aseptic loosening compared to non-retentive implants

Implant designs for hip and knee arthroplasty have undergone a continual improvement process, but development of implants for total elbow arthroplasty (TEA) have lagged behind despite the marked mechanical burden placed on these implants. TEA is not as durable with failure rates approaching thirty percent at five years. The Coonrad-Morrey (Zimmer, Warsaw, IN), a linked design, remains the standard-bearer, employing polyethylene bushings through which a metal axle passes. A common failure mode is bushing wear and deformation, causing decreased joint function as the bushing-axle constraint decreases and osteolysis secondary to release of large volumes of wear debris. Improving upon this poor performance requires determining which factors most influence failure, so that failure can be avoided through design improvements. The approach integrates clinical observations of failed TEAs with implant retrieval analysis, followed by measurements of loads across the elbow for use in stress analyses to assess the performance of previous designs, and, finally, new design approaches to improve performance. Examination of the clinical failures of more than seventy Coonrad-Morrey TEAs revealed patterns of decreased constraint and stem loosening. Implant retrieval analysis from more than thirty of these cases showed excessive bushing deformation and wear and burnishing of the fixation stems consistent with varus moments across the joint. To determine loads across the elbow, motion analysis data were collected from eight TEA patients performing various activities of daily living. The kinematic data were input into a computational model to calculate contact forces on the total elbow replacement. The motion that produced the maximum contact force was a feeding motion with the humerus in 90° of abduction. For this motion, the joint reaction forces and moments at the point of maximum contact were determined from a computational model. We applied these loads to numerical models of the articulating bushings and axle of the Coonrad-Morrey to examine polyethylene strains as measures of damage and wear. Strain patterns in response to the large varus moment applied to the elbow during feeding activities showed extensive plastic deformation in the locations at which deformation and wear damage were observed in our retrieved implants (Fig. 1). Finally, we examined a new semi-constrained design concept intended to meet two goals: transfer contact loads away from the center of the joint, thus allowing contact to provide a larger internal moment to resist the large external varus moment; and reduce polyethylene strains by utilizing curved contacting surfaces on both the axle and the bushings (Fig. 2). After a sensitivity analysis to determine optimal dimensional choices (e.g., bushing and axle radii), we compared the resulting polyethylene strains between the Coonrad-Morrey and new design at locations that experienced the largest strains (Fig. 3). Substantial decreases were achieved, suggesting far less deformation and wear, which should relate to marked improvements in performance. Currently, we are incorporating this new design concept, along with alterations in stem design achieved from examination of load transfer at the fixation interfaces based on the same loading conditions, to achieve an implant system intended to improve the performance of TEA

Total Elbow arthroplasty can be a valuable treatment option in the painful or stiff elbow but outcomes have been disappointing previously. The history of total elbow arthroplasty has been disappointing in the past. Implants initially were a coupled articulation and were a rigid hinge. There was then a move to resurfacing type of designs although there was an issue with instability postoperatively with these implants. The semiconstrained coupled implant was developed in the mid 1970s by Coonrad. The idea behind the implant was that the loose polyethylene coupling provides inherent stability while decreasing the amount of loosening that was seen with the rigid hinge implants previously. We are reporting our results of our experience with a single type of semiconstrained implant that has been used in our unit since 1999. A semiconstrained total elbow arthroplasty was performed in thirteen patients over a period of 7 years period in our unit. Mean age at time of surgery was 60 years (44–70) M:F ratio 11:2. The aetiology of the joint pathology was Rheumatoid Arthritis (n= 10), psoriatic arthritis (n= 2) & posttraumatic (n =1). The patients were followed up for a mean duration of 4.5 years. They were assessed for range of motion, Mayo elbow function scores and radiographic evaluation and complication rate. 9 of the 13 elbows had a good to excellent result. There were 5 complications overall. There was two ulnar neuropathies that eventually resolved and one ulnar component that had to be revised 2 weeks after initial insertion. 3 had condylar fractures none of which required further operation. One patient had evidence of radiographic loosening but was asymptomatic. In our experience the semiconstrained total elbow replacement is a valuable option in the treatment of painful stiff the elbow

This study reviews the predisposing features, the clinical, and laboratory findings at the time of diagnosis and the results of single-stage revision of prosthetic replacement of the elbow for infection. Deep infection occurred in six of 305 (1.9%) primary total elbow replacements. The mean follow-up after revision was 6.8 years (6 months to 16 years) and the mean age at the time of revision was 62.7 years (56 to 74). All six cases with infection had rheumatoid arthritis and had received steroid therapy. The infective organism was Staphylococcus aureus. Four of the six elbows had a developed radiolucency around one component or the other. Successful single-stage exchange arthroplasty was carried out with antibiotic-loaded cement in five of the six cases. In one, the revision prosthesis had to be removed following recurrence of the infection. The functional result was good in three elbows, fair in one, poor in one and fair in the resection arthroplasty

We analysed the outcome of the Coonrad-Morrey total elbow replacement used for fracture of the distal humerus in elderly patients with no evidence of inflammatory arthritis and compared the results for early versus delayed treatment. We studied a total of 32 patients with 15 in the early treatment group and 17 in the delayed treatment group. The mean follow-up was 56.1 months (18 to 88). The percentage of excellent to good results based on the Mayo elbow performance score was not significantly different, 84% in the early group and 79% in the delayed group. Subjective satisfaction was 92% in both the groups. One patient in the early group developed chronic regional pain syndrome and another type 4 aseptic loosening. Two elbows in the early group also showed type 1 radiological loosening. Two patients in the delayed group had an infection, two an ulnar nerve palsy, one developed heterotopic ossification and one type 4 aseptic loosening. Two elbows in this group also showed type 1 radiological loosening. The Kaplan-Meier survivorship analysis for the early and delayed treatment groups was 93% at 88 months and 76% at 84 months, respectively. No significant difference was found between the two groups

We examined the effects of previous resection of the radial head and synovectomy on the outcome of subsequent total elbow arthroplasty in patients with rheumatoid arthritis. Fifteen elbows with a history of resection and synovectomy were compared with a control group of patients who had elbow arthroplasty with an implant of the same design. The mean age in both groups was 63 years. In the study group, resection of the radial head and synovectomy had been undertaken at a mean of 8.9 years before arthroplasty. The mean radiological follow-up for the 13 available patients in the study group was 5.89 years (0.3 to 11.0) and in the control group was 6.6 years (2.2 to 12.6). There were no revisions in either group. The mean Mayo elbow performance score improved from 29 to 96 in the study group, with similar improvement in the control group (28 to 87). The study group had excellent results in 13 elbows and good results in two. The control group had excellent results in seven and good results in six. Our experience indicates that previous resection of the radial head and synovectomy are not associated with an increased rate of revision following subsequent arthroplasty of the elbow. However, there was a higher rate of complication in the study group compared with the control group

To show the role and effectiveness of semi-constrained total elbow arthroplasty in restoring elbow function in severe, irreversible post-traumatic osseous and chondral injuries. Eighteen patients, aged 19–80, 11 male and 7 female, suffering from serious, irreversible anatomical and functional lesions of the elbow joint due to previous severe untreated or inadequately treated fractures (T-type transcondylar, trochlear-condylar, open fxs with large bony defects, severe osteochondral, heterotopic ossification in ICU fracture patients). Postop follow up was 9–57 months. All patients were treated with modular, cemented, semi-constrained linked total elbow arthroplasty. A functional brace was used post-operatively, and motion was permitted on the 3rd post-op day. The patients were allowed a full range of motion at 1 week post-op and they were subjected to vigorous physiotherapy. Post-op results were evaluated by using Mayo, DASH, quick-DASH scores and measuring grip strength and range of motion. Our results ranged from satisfactory to excellent in 16 patiens, with good strength and wide motion arc (with up to 15o extension-flexion deficit). One old female patient suffered a severe cerebral stroke with a bad outcome. In another young male patient the motion arc reached only 40% of the normal (spasticity, ICU patient with brain injury). Semi-constrained linked total elbow arthroplasty proves to be an effective method of treatment in severe, irreversible, intraarticular post-traumatic elbow injuries with chondral destruction and grave functional deficit, provided the proper technique is employed and a vigorous rehabilitation program is followed

Aim:. To investigate the incidence of post-operative ulna nerve symptoms in total elbow arthroplasty after full in-situ release. Methods:. A retrospective review was completed of the medical records of eighty-three consecutive primary total elbow arthroplasties (TEA) performed between 2003 and 2012. Data analysed included the presence of pre-operative ulnar nerve (UN) symptoms, history of prior UN transposition, intra-operative management of the UN and presence of post-operative symptoms. Results:. One patient had a prior UN transposition. The nerve was transposed at time of TEA in 4 of the 83 elbows (4.8%). The indication for transposition in all 4 cases was abnormal tracking or increased tension on the nerve after insertion of the prosthesis. The remaining 78 TEA's all received a full in-situ release of the nerve. The incidence of post-operative UN symptoms in this group was 7.7% (6/78). Four neuropraxias resolved in the early post-operative period, whilst two patients (2.6%) continued to experience significant UN symptoms requiring subsequent transposition, at 6 weeks and 12 months post TEA. Conclusion:. A 2.6% incidence of significant post-operative UN symptoms compares favourably with systematic reviews in the literature (3–11% incidence of UN complications). We do not believe routine transposition, which adds to the handling of the nerve and increases total surgical time, is necessary, and should be reserved for cases where intra-operative assessment by the surgeon deems it necessary

Total elbow arthroplasty (TEA) usage is increasing owing to expanded surgical indications, better implant designs, and improved long-term survival. Correct humeral implant positioning has been shown to diminish stem loading in vitro, and radiographic loosening in in the long-term. Replication of the native elbow centre of rotation is thought to restore normal muscle moment arms and has been suggested to improve elbow strength and function. While much of the focus has been on humeral component positioning, little is known about the effect of positioning of the ulnar stem on post-operative range of motion and clinical outcomes. The purpose of this study is to determine the effect of the sagittal alignment and positioning of the humeral and ulnar components on the functional outcomes after TEA. Between 2003 and 2016, 173 semi-constrained TEAs (Wright-Tornier Latitude/Latitude EV, Memphis, TN, USA) were performed at our institution, and our preliminary analysis includes 46 elbows in 41 patients (39 female, 7 male). Patients were excluded if they had severe elbow deformity precluding reliable measurement, experienced a major complication related to an ipsilateral upper limb procedure, or underwent revision TEA. For each elbow, saggital alignment was compared pre- and post-operatively. A best fit circle of the trochlea and capitellum was drawn, with its centre representing the rotation axis. Ninety degree tangent lines from the intramedullary axes of the ulna and humerus, and from the olecranon tip to the centre of rotation were drawn and measured relative to the rotation axis, representing the ulna posterior offset, humerus offset, and ulna proximal offset, respectively. In addition, we measured the ulna stem angle (angle subtended by the implant and the intramedullary axis of the ulna), as well as radial neck offset (the length of a 90o tangent line from the intramedullary axis of the radial neck and the centre of rotation) in patients with retained or replaced radial heads. Our primary outcome measure was the quickDASH score recorded at the latest follow-up for each patient. Our secondary outcome measures were postoperative flexion, extension, pronation and supination measured at the same timepoints. Each variable was tested for linear correlation with the primary and secondary outcome measures using the Pearson two-tailed test. At an average follow-up of 6.8 years (range 2–14 years), there was a strong positive correlation between anterior radial neck offset and the quickDASH (r=0.60, p=0.001). There was also a weak negative correlation between the posterior offset of the ulnar component and the qDASH (r=0.39, p=0.031), and a moderate positive correlation between the change in humeral offset and elbow supination (r=0.41, p=0.044). The ulna proximal offset and ulna stem angle were not correlated with either the primary, or secondary outcome measures. When performing primary TEA with radial head retention, or replacement, care should be taken to ensure that the ulnar component is correctly positioned such that intramedullary axis of the radial neck lines up with the centre of elbow rotation, as this strongly correlates with better function and less pain after surgery

Distal humeral fractures are difficult fractures to treat. In the elderly population the problems are compounded by gross comminution and osteoporosis. Concurrent presence of rheumatoid arthritis makes the problem more difficult. Open reduction and internal fixation of such fractures have been shown to give poor results. Total elbow replacement has been recommended as an alternative solution to this difficult problem. We present the results of a retrospective review of a small group of elderly patients who underwent total elbow arthroplasty in our unit for comminuted fractures of the distal end of the humerus. We have followed up seven patients (seven elbows) with a mean age of 81. 7 years (range 74. 1 to 87. 8) at the time of injury. The presence of rheumatoid arthritis in three of them influenced the choice of treatment. All replacements were performed using the semiconstrained Coonrad-Morrey elbow replacement prosthesis. The duration of follow up at present is between two and four years. None of the patients have been lost to follow up. At the latest follow up the mean arc of flexion was 20 to 130 degrees. 6 of the patients had no pain while 1 complained of mild pain. All elbows were stable. The Mayo Elbow Performance Score (MEPS) for five elbows was excellent, two scored good. The mean MEPS for all the elbows was 92/100. There were 2 cases of superficial wound infection and no cases of deep infection, ulnar nerve neuritis or component failure. These results suggest that a semiconstrained total elbow replacement has a role to play in the treatment of carefully selected distal humeral fractures, which cannot be treated by internal fixation due to extensive intraarticular comminution and gross osteopenia. Although these are short-term follow up results they are encouraging outcomes for treatment of one of the most challenging fractures

Summary Statement. Discovery system produced effective functional improvement in both primary and revision total elbow replacement. The incidence of major complications was in an acceptable range. Introduction. The search for the ideal elbow prosthesis continues as instability and loosening remain the prime reasons for total elbow replacement (TER) failure. The Discovery Elbow System (Biomet) is one of the latest generations of linked prosthesis and has been used in UK since 2003. We report outcome of TER using this system. Methods. A total of 100 TERs (75 primary, 25 revisions) were performed between 2003 and 2010. The main primary underlying pathologies for TER were advanced rheumatoid arthritis (N=58), osteoarthritis (N=35), acute fractures (N=7). There were 60 female and 40 male patients with an average age of 62 years. The outcome assessment included pain, patient satisfaction, Liverpool Elbow Score (LES), range of movement, and imaging during a mean follow-up period of 48.5 months. Major complications are also reported. Results. For the whole patient group (primary + revision), the LES was significantly (p<0.001) improved from 3.79+/−1.71 to 6.36+/−1.85There were significant improvements in elbow flexion from 100°+/−24 to 118°+17, supination from 38°+/−26 to 50°+/−25 and pronation from 48°+/−22 to 61°+/−21. Mean improvement in flexion-extension and pronation-supination arc was 20° and 25°, respectively. 64% of cases were completely pain-free and at the final follow-up (compared to 7% preoperatively). Only 6% of patients scored “Not Satisfied” at the final follow-up. LES improvement was significantly higher in the primary TER compared to revision TER (p<0.05). Imaging reviewed for 60 cases showed loosening in 4% of patients. Other main complications included deep infection (N=2), ulnar neuropathy (N=3), pre-prosthetic fracture (N=2), and prosthetic failure (N=1). Discussion. TER using the Discovery Elbow System is an effective arthroplasty in terms of functional improvement, pain relief and range of motion in both primary and revision patients. TER resulted in no/mild pain in 78% of cases. Patients undergoing Acclaim, Souter-Strathclyde, GSB III, and Coonrad-Morrey TER have been reported to have no/mild pain in 64%, 67%, 50–92% and 60–100% of cases, respectively. A 20° improvement in flexion-extension arc is comparable to that of Acclaim (23°), Souter-Strathclyde (15°), GSBIII (19–33°), and Coonrad-Morrey (17–26°) TER. An improvement of 25° in pronation-supination arc in our series is also comparable to that of 21–28° reported the Coonrad-Morrey and 27–33° for Discovery prostheses. An infection rate of 2% is lower than several other reports for GSB III TER (7–11%) and Coonrad-Morrey (6–8%). The incidence of persistent ulnar neuropathy (3%) was lower compared to GSBIII TER (11–14%), Coonrad-Morrey (12–26%), and Acclaim (8%)

Aims. Revision total elbow arthroplasty (TEA) is often challenging. The aim of this study was to report on the clinical and radiological results of revision arthroplasty of the elbow with the Latitude TEA. Patients and Methods. Between 2006 and 2010 we used the Latitude TEA for revision in 18 consecutive elbows (17 patients); mean age 53 years (28 to 80); 14 women. A Kudo TEA was revised in 15 elbows and a Souter-Strathclyde TEA in three. Stability, range of movement (ROM), visual analogue score (VAS) for pain and functional scores, Elbow Functional Assessment Scale (EFAS), the Functional Rating Index of Broberg and Morrey (FRIBM) and the Modified Andrews’ Elbow Scoring System (MAESS) were assessed pre-operatively and at each post-operative follow-up visit (six, 12 months and biennially thereafter). Radiographs were analysed for loosening, fractures and dislocation. The mean follow-up was 59 months (26 to 89). Results. The ROM of the elbow did not improve significantly. The mean EFAS and MAESS scores improved significantly six months post-operatively (18.6 points, standard deviation (. sd. ) 7.7; p = 0.03 and 28.8 points, . sd . 8.6; p = 0.006, respectively) and continued to improve slightly or reached a plateau. The mean pain scores at rest (Z = -3.2, p = 0.001) and during activity (Z = -3.2, p = 0.001), and stability (Z = -3.0, p = 0.003) improved significantly six months post-operatively. Thereafter scores continued to improve slightly or a plateau was reached. There were no signs of loosening. Conclusion. Revision surgery using the Latitude TEA results in improvement of functionality, reduced pain and better stability of the elbow. Improvement of ROM of the elbow should not be expected.

We report our experience of staged revision surgery for the treatment of infected total elbow arthroplasty (TEA). Between 1998 and 2010 a consecutive series of 33 patients (34 TEAs) underwent a first-stage procedure with the intention to proceed to second-stage procedure when the infection had been controlled. A single first-stage procedure with removal of the components and cement was undertaken for 29 TEAs (85%), followed by the insertion of antibiotic-impregnated cement beads, and five (15%) required two or more first-stage procedures. The most common organism isolated was coagulase-negative Staphylococcus in 21 TEAs (62%). A second-stage procedure was performed for 26 TEAs (76%); seven patients (seven TEAs, 21%) had a functional resection arthroplasty with antibiotic beads in situ and had no further surgery, one had a persistent discharge preventing further surgery. There were three recurrent infections (11.5%) in those patients who underwent a second-stage procedure. The infection presented at a mean of eight months (5 to 10) post-operatively. The mean Mayo Elbow Performance Score (MEPS) in those who underwent a second stage revision without recurrent infection was 81.1 (65 to 95). Staged revision surgery is successful in the treatment of patients with an infected TEA and is associated with a low rate of recurrent infection. However, when infection does occur, this study would suggest that it becomes apparent within ten months of the second stage procedure. Cite this article: Bone Joint J 2013;95-B:1681–6

Background. The quest for the perfectly designed elbow prosthesis continues as instability and loosening remain the foremost reasons for the failure of total elbow replacement (TER). The Discovery® Elbow System (Biomet, UK) (Figure 1), which has been used in UK since 2003, is one of the latest generations of linked prosthesis. This system was designed to decrease polyethylene-bushing wear, improve anatomic stem design, restore elbow joint biomechanics, and produce a hinge that could be easily revised. This report describes the short term outcome of TER using the Discovery® Elbow System. Patients and Methods. A total of 60 TERs including 48 primary and 12 revisions were performed between 2003 and 2008. Patients included 21 males (37%) and 36 females (63%) with a mean age of 63 years. The indications for primary TER were advanced rheumatoid arthritis (n=19), osteoarthritis (n=16), post traumatic osteoarthritis (n=9), acute fractures (n=3), and haemophilic arthropathy (n=1). The outcome was assessed using pain score, Liverpool Elbow Score (LES), and range of movement during a mean follow-up of 26 months. Associated complications were documented. Radiological assessment included evaluation for loosening, instability and periprosthetic fractures. Results. The mean LES was significantly (p<0.001) improved from 3.8 (±1) pre-operatively to 6.9 (±2) at the final follow- up. Significant improvements were noted in elbow flexion from 100° (±22) to 120° (±15), supination from 41° (±28) to 65° (±20) and pronation from 52° (±22) to 72° (±18). There was no significant change in elbow extension. Mean improvement in flexion-extension and pronation-supination arc was 22° and 44°, respectively. 46 cases (77%) were completely pain-free at the final follow-up. The main complications included deep infection (4 cases – treated with staged revision TER), postoperative ulnar neuropathy (3 cases–treated with decompression), intra-operative fractures of medial condyle (3 cases – treated non-operatively with brace), and elbow haemarthrosis (1 case). Discussion. TER with Discovery® Elbow System resulted in either no pain or mild pain in 87% of cases. Patients undergoing Acclaim, Souter-Strathclyde, GSB III, and Coonrad-Morrey TER have been reported to have no/mild pain in 64%, 67%, 50–92% and 60–100% of cases, respectively. A 22° improvement in flexion-extension arc is comparable to that of Acclaim (23°), Souter-Strathclyde (15°), GSB III (19–33°), and Coonrad-Morrey (17–26°) TER. An improvement of 44° in pronation-supination arc in our series is also comparable to that of 31–67° reported for GSB III and higher than the Coonrad-Morrey prosthesis (21–28°). In terms of complications, an infection rate of 6.7% is consistent with those reported for GSB III TER (7–11%) and Coonrad-Morrey (6–8%). The incidence of persistent ulnar neuropathy was lower compared to GSB III TER (11–14%), Coonrad-Morrey (12–26%), and Acclaim (8%). While the survival of Discovery TER was 93%, the survival of GSB III (5–6 years) and Coonrad-Morrey (5 years) has been reported as 71–85% and 72–90%. The results indicate that Discovery® Elbow System is an effective device for total elbow arthroplasty in terms of functional improvement, pain relief and range of motion at short-term follow-up

40 linked total elbow replacements were inserted into 35 patients over a 12-year period. The mean age was 67. 3 years, (range 48 to 87 years) and the mean follow up 50 months (range 8 to 134 months). Each patient had undergone at least 1 operation prior to the index arthroplasty (range 1 to 10). 27 elbows were flail and 13 unstable due to previous failed total elbow replacements in 23, gross bony erosion due to rheumatoid arthritis in 9, distal humeral non-union in 6 and Charcot joints due to syringomyelia in 2. A Coonrad Morrey sloppy hinge prosthesis was implanted in 25 elbows and a snap-fit Souter Strath-clyde prosthesis in 15. The technique included preservation of the triceps mechanism and early mobilisation in most cases. At review 38 elbows had no or mild pain, 2 moderate, and no patient had severe pain. All patients achieved a functional range of movement. There was no linkage failure of any implant. Complications included revision for aseptic loosening of one humeral and one ulnar component, debridement for infection in one and curettage and bone grafting of a cement granuloma in one. One patient with a Charcot joint developed a non-union after failure of plating and grafting of a periprosthetic fracture at the tip of the humeral component. In addition six had delayed wound healing, two ulnar nerve symptoms and two triceps weakness. In conclusion, a linked elbow replacement can reliably provide stability, mobility and pain relief in a flail or unstable joint allowing the hand to be positioned in space and therefore the function of the limb is dramatically improved. This method is especially appropriate in elderly frail patients

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

Background: Total elbow prostheses are broadly classified into linked and the unlinked categories. We have looked at long-term results of unlinked Kudo 5 total elbow replacement used in the treatment of patients with rheumatoid arthritis in 2 hospitals. Methods: 87 Kudo 5 Total elbow replacements in 70 patients with adult rheumatoid arthritis were performed at Wexham Park Hospital, Slough and City Hospital, Nottingham by 2 specialist elbow surgeons, the senior authors. 16 patients had died and 8 patients were lost to follow up. 62 elbow replacements in 46 patients were evaluated at a mean follow up of 79 months [29–137 months] using the Mayo Clinic Performance Index. Postoperative radiographs were also reviewed for loosening using standard anteroposterior and lateral films. Results: Preoperatively 6 had moderate pain and 56 had severe pain. Postoperatively the pain was rated as none or mild by 58 and moderate by 4. The average Mayo Elbow Score improved from 37 preoperatively to 86 postoperatively. The mean arc of flexion/extension improved from 60 to 99 degrees. There were 14 complications including ulnar neuropraxia, fracture, dislocation, triceps rupture and loosening. 4 cases were revised, 2 for aseptic and 2 for septic loosening. Postoperative radiographs showed 5 cases with loosening around the ulna component. Conclusions: The long-term results using the Kudo 5 elbow prosthesis in patients with rheumatoid arthritis are acceptable and comparable to other series reported of this implant. To date this is the largest series reported with the longest follow up using this implant
