Abstract
Background Total elbow arthroplasty (TEA) is a valuable therapeutic approach for improving function and relieving pain in severely deformed elbow joints. However, TEA is associated with a high incidence of complications. In Japan, the use of unlinked TEA has a long history, with the development of the Kudo prosthesis marking a significant milestone. Subsequently, various unlinked implant designs have been developed. Although favorable long-term clinical results have been reported, complications remain a concern. To further improve the outcome of unlinked TEA, attempts have been made in recent years to develop various surgical approaches and intraoperative support devices. This review focuses on the clinical outcomes and recent advances in unlinked TEA in Japan. Methods A comprehensive review of clinical results and advancements in unlinked TEA in Japan was conducted. The analysis included trends in the number of TEA, medium-term and long-term results for unlinked TEA, surgical approaches, or preoperative planning techniques. Results Several implant designs have been developed in Japan. Clinical studies have reported satisfactory long-term outcomes with these implants, but complications, such as infection, fractures, and dislocation, have been observed. In order to enhance the outcomes of unlinked TEA, various triceps-on approaches have been developed as alternatives to the triceps-detaching approach, which compromises the continuity between the triceps tendon and ulna, leading to inevitable complications related to the triceps tendon. Preservation or repair of the surrounding soft tissues is considered critical for preventing postoperative instability due to the absence of a radial head in the current unlinked TEA design. Computed tomography-based 3-dimensional preoperative planning has been pioneered in Japan, demonstrating its effectiveness in predicting implant size and achieving appropriate implant placement. Additionally, augmented reality-assisted surgery is being explored to accurately translate preoperative planning into the surgical procedure. Conclusion Unlinked TEA for inflammatory arthritis has exhibited promising long-term results in Japan, with ongoing efforts to improve surgical techniques and preoperative planning. Further advancements are anticipated to prevent complications such as dislocation and peri-implant fractures.

Clinical and Radiographic Outcomes of Total Elbow Arthroplasty Using a Semi-constrained Prosthesis with a Triceps-preserving Approach over a Minimum Follow-up Period of 4 Years. Orthop Surg 2023; 15:2091-2101. [PMID: 37076437 PMCID: PMC10432419 DOI: 10.1111/os.13698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 02/10/2023] [Accepted: 02/10/2023] [Indexed: 04/21/2023] Open
Abstract
OBJECTIVE Complications related to triceps after total elbow arthroplasty (TEA) have become a major surgical concern. The triceps-preserving approach has the advantage of not disturbing the insertion of triceps but is disadvantaged by the reduced exposure of the elbow joint. The aim of this study was to investigate the clinical and radiological outcomes of TEA with a triceps-preserving approach and to compare the outcomes of TEA to treat arthropathy with that of TEA to treat acute distal humerus fracture. METHODS From January 2010 to December 2018, 23 patients undergoing primary TEAs were retrospectively reviewed with a mean follow-up time of 92.6 months (range, 52-136 months). Each TEA was performed using the triceps-preserving approach with a semi-constrained Coonrad-Morrey prosthesis. Patient demographics, range of motion (ROM), pain visual analogue scale (VAS), and triceps strength (Medical Research Council [MRC] scale) were compared before and after surgery. The Mayo Elbow Performance Score (MEPS), Disabilities of the Arm, Shoulder, and Hand (DASH) score, radiographic outcome, and complications were evaluated at follow-up. RESULTS In total, seven males and 16 females were included in this study, with a mean age of 66.1 years (range:46-85 years). By the last follow-up, pain had been significantly relieved in all patients. The average MEPS in the arthropathy group and fracture group were 90.8 ± 10.3 points (range: 68-98 points) and 91.7 ± 0.4 (range: 76-100 points), respectively. The average DASH of the arthropathy group and fracture group was 37.3 ± 18.8 points (range: 18-52 points) and 38.4 ± 20.1 (range: 16-60 points). At the last follow-up after surgery, the mean flexion arcs in the arthropathy group and fracture group were 100.4° ± 24.1° and 97.8° ± 28.1°, respectively. The mean pro-supination arcs in the arthropathy group and fracture group were 142.4° ± 15.2° and 139.2° ± 17.5°, respectively. There were no significant differences in clinical outcomes between the two groups (P ≥ 0.05). Triceps strength was normal (MRC grade V) in 15 elbows and good in eight elbows. None of the cases experienced weakness of the triceps strength, infection, periprosthetic fractures, or prosthesis breakage. CONCLUSIONS The clinical and radiographical outcomes of TEA with the triceps-preserving approach were satisfactory in patients with distal humerus fracture, osteoarthritis and rheumatoid arthritis.

Bilateral triceps tendon approach is flexible and efficient in the treatment of type C distal humerus fractures. Chin J Traumatol 2022; 25:145-150. [PMID: 34920951 PMCID: PMC9125722 DOI: 10.1016/j.cjtee.2021.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 08/28/2021] [Accepted: 11/12/2021] [Indexed: 02/04/2023] Open
Abstract
PURPOSE The purpose of this study was to assess and compare elbow range of motion, triceps extension strength and functional results of type C (AO/OTA) distal humerus fractures treated with bilateral triceps tendon (BTT) approach and olecranon osteotomy (OO). At the same time, we are also trying to know whether BTT approach can provide sufficient vision for comminuted intra-articular fractures of the distal humerus, and whether it is convenient to convert to the treatment to total elbow arthroplasty (TEA) or OO. METHODS Patients treated with OO and BTT approaches for type C distal humerus fractures between July 2014 and December 2017 were retrospectively reviewed. Inclusion criteria include: (1) patients' age were more than 18 years old, (2) follow-up was no less than 6 months, and (3) patients were diagnosed with type C fractures (based on the AO/OTA classification). Exclusion criteria include: (1) open fractures (Gustillo type 2 or type 3), (2) treated by other approaches, and (3) presented with combined injuries of ipsilateral upper extremities, such as ulnar nerve. Elbow range of motion and triceps extension strength testing were completely valuated, when the fractures had healed. Assessment of functional results using the Mayo elbow performance score and complications were conducted in final follow-up. The data were compared using the two tailed Student's t-test. All data were presented as mean ± standard deviation. RESULTS Eighty-six patients of type C distal humerus fractures, treated by OO and BTT approach were retrospectively reviewed between July 2014 and December 2017. Fifty-five distal humerus fractures (23 males and 32 females, mean age 52.7 years) treated by BTT approach or OO were included in this study. There were 10 fractures of type C1, 16 type C2 and 29 type C3 according to the AO/OTA classification. Patients were divided into two surgical approach groups chosen by the operators: BTT group (28 patients) and OO group (27 patients). And the mean follow-up time of all patients was 15.6 months (range, 6-36 months). Three cases in BTT group were converted to TEA, and one converted to OO. Only one case in BTT group presented poor articular reduction with a step more than 2 mm. There were not significantly different in functional outcomes according to the Mayo elbow performance score, operation time and extension flexion motion are values between BTT group and OO group (p > 0.05). Complications and reoperation rate were also similar in the two groups. Triceps manual muscle testing were no significant difference in the two groups, even subdivided in elder patients (aged >60 years old). CONCLUSION BTT is a safe approach to achieve similar functional result comparing with OO. BTT were not suitable for every case with severe comminuted pattern, but it avoids the potential complications related to OO, and has no complications concerning with triceps tendon. It is convenient for open reduction internal fixation and flexible to be converted to OO, as well as available to be converted to TEA in elder patients.

Abstract
BACKGROUND Surgical management of the triceps during exposure for total elbow arthroplasty (TEA) is critical to a successful outcome. Previously described techniques include elevating the triceps insertion from one side or leaving the triceps insertion attached and dislocating the joint. Another approach to the elbow, first described in 1933 by Willis Campbell, MD, and subsequently modified by George Van Gorder, MD, involves turning down the triceps tendon without disrupting the triceps insertion. This approach offers complete visualization of the joint and provides excellent exposure for TEA. Only the original report of the technique and a small series of patients using this technique for TEA exist in the literature. The goal of this study was to evaluate outcomes of the Van Gorder approach in a large series of patients undergoing TEA. METHODS All patients who underwent TEA from 2008 to 2016 were retrospectively reviewed. Only patients who underwent primary TEA performed through the Van Gorder approach with at least 6 months' follow-up were included for analysis. Patients with prior elbow surgery were excluded. Demographic data, indication for surgery, postoperative range of motion, triceps function, and need for additional surgery were recorded. Prospectively collected visual analog scale (VAS) and Global Health Quality of Life scores were also analyzed. RESULTS A total of 53 patients met inclusion criteria. The mean age was 62 years, 81% were female, and the average follow-up was 30.2 months. The most common surgical indications included inflammatory arthritis (47%), osteoarthritis (24%), and fracture (19%). Postoperatively, average elbow arc of motion was an 8°-137°. There was 1 patient (1.89%) who developed failure of their triceps extension mechanism. A total of 10 patients (19%) underwent additional elbow surgery most commonly for superficial wound complications. Preoperative VAS scores decreased significantly, starting at 3 months postoperatively (6.76 to 3.37, P < .001), and remained constant at the 12- and 24-month postoperative visits. CONCLUSIONS This is the largest study evaluating the Van Gorder surgical approach to the elbow for primary TEA with an average follow-up of 32 months. Overall rates of triceps failure and reoperation are consistent with other approaches for TEA.

Abstract
Total elbow arthroplasty (TEA) is associated with a relatively high incidence of chronic triceps insufficiency, but there is difficulty in treatment. This case series describes reconstruction with Achilles allografts using the keyhole technique in patients with postoperative chronic triceps insufficiency. Fourteen patients who underwent reconstruction for triceps insufficiency after TEA were included in the study. During this procedure, a keyhole-shaped osteotomy was performed on the proximal olecranon, and a fragment of the calcaneal allograft was shaped into a bone plug to fit the olecranon. The clinical outcomes were assessed in all patients 12 months after reconstruction and at last follow-up (range, 13-54 months). After 12 months, patients had a mean Mayo Elbow Performance Score of 84.3 (range, 75-100), and all achieved a marked improvement compared with before reconstruction (mean, 42.7; range, 20-75). Seven, 4, and 3 patients achieved excellent, good, and fair outcomes, respectively. The mean extension peak torque of the operated-on arm was 34.91 Nm (range, 16.3-63.9 Nm), and the percentage of extension peak torque of the operated-on arm to the opposite arm was from 14.5% preoperative to 76.2% 12 months postoperative. This case series suggests that triceps reconstruction with an Achilles tendon using the keyhole technique is a useful treatment option for triceps insufficiency after TEA.

Abstract
BACKGROUND The incidence of triceps insufficiency after total elbow arthroplasty (TEA) varies in the literature, and a consensus on treatment strategy is lacking. We review the incidence, the risk factors, the clinical presentation, and the diagnosis and treatment of triceps insufficiency after TEA. Based on this information, we have formulated recommendations for clinical practice. METHODS We performed a systematic review of the literature from January 2003 to April 2020 to identify studies that investigated triceps function following TEA by searching the PubMed, Cochrane, and Embase databases. Eligible studies (1) reported on triceps function following primary or revision TEA for every indication, regardless of technique (e.g., bone grafts), (2) included ≥6 adult patients, (3) had the full-text article available, and (4) had a minimum follow-up of 1 year. RESULTS Eighty studies with a total of 4,825 TEAs were included. The quality was low in 15 studies, moderate in 64 studies, and high in 1 study. The mean incidence of triceps insufficiency was 4.5%. The rates were highest in patients after revision TEA (22%), in those with posttraumatic arthritis as an indication for surgery (10.2%), and after a triceps-reflecting approach (4.9%). Most studies used the Medical Research Council scale to score triceps function, although cutoff points and the definition of triceps insufficiency differed among studies. Surgical treatment showed favorable results with anconeus tendon transfer and Achilles allograft repair when compared with direct repair. CONCLUSIONS The incidence of triceps insufficiency varies greatly, probably due to a lack of consensus on the definition of the term. Therefore, we recommend the guidelines for clinical practice that are presented in this article. These guidelines assist clinicians in providing the best possible treatment strategy for their patients and help researchers optimize their future study designs in order to compare outcomes.

Abstract
PURPOSE Triceps-sparing (TS) approaches have been reported to provide improved triceps strength, better patient outcomes, and a lower incidence of complications in primary total elbow arthroplasty (TEA). It remains unclear whether the advantages of this approach are similar in the revision setting, especially in cases with prior triceps detachment. The purpose of this study was to compare triceps strength and clinical outcomes between TS and triceps-detaching (TD) approaches in revision TEA. METHODS All revision TEAs performed over a 17-year period with a minimum 1-year follow-up were retrospectively reviewed. Elbows with preoperative triceps insufficiency or subsequent component removal for infection were excluded. Patients were grouped according to the surgical approach performed at the last revision TEA. Outcome measures included triceps strength, range of motion, visual analog scale (VAS), Mayo Elbow Performance Score (MEPS), and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. RESULTS Ten TS and 6 TD elbows were evaluated. Four elbows within the TS group had documented TD surgery prior to revision. Median follow-up was longer in the TD group (137 ± 75 months vs 53 ± 20 months). Functional strength and DASH scores were significantly better in the TS group. Arc of motion, VAS, and MEPS were similar between the TS and the TD groups. CONCLUSIONS The TS approach preserves greater postoperative functional triceps strength after revision TEA, regardless of the type of approach used previously.

Abstract
Indications for total elbow arthroplasty (TEA) were traditionally reserved for patients with advanced rheumatoid disease and posttraumatic conditions of the elbow. The indications have expanded for TEA to include patients with acute elbow trauma, dysfunctional instability, and end-stage osteoarthritis. Many of these patients are younger and place a greater demand on their TEA. This evolution of TEA use combined with the concern of soft tissue handling and triceps function has led to increased interest regarding surgical exposure for TEA. Three generalized approaches to TEA are predicated on the handling of the triceps tendon: triceps reflecting, triceps splitting, and triceps sparing. Each of these approaches has its own inherent advantages and disadvantages. As indications grow for TEA and the possibility of revision surgery increases with use in younger, higher demand patients, it is important for treating surgeons to use these various exposures so that they are capable of treating patients in a variety of settings.

Abstract
BACKGROUND 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 the incidence, risk factors, prophylaxis, and management of HO after TEA. METHODS A systematic search was conducted using MEDLINE, Embase, and PubMed to retrieve all relevant studies evaluating the occurrence of HO after TEA. The search was performed in duplicate, and a quality assessment of all included studies was performed. RESULTS A total of 1907 studies were retrieved, of which 45 were included involving 2256 TEA patients. HO was radiographically present in 10% of patients and was symptomatic in 3%. Fewer than 1% of patients went on to undergo surgical excision of HO, with outcomes after surgery reported as good or excellent as assessed by range of motion and the Mayo Elbow Performance Score. HO appears more likely to develop in patients undergoing TEA because of ankylosis, primary osteoarthritis, and distal humeral fractures. Surgical intervention is more likely to be required in patients in whom HO develops after TEA performed for ankylosis and post-traumatic osteoarthritis. CONCLUSION HO is an uncommon complication after TEA, with most patients in whom HO develops 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.

Abstract
Introduction This retrospective review investigates whether the triceps-on approach obtains alignment of total elbow arthroplasty implants equivalent to a triceps-off approach. Methods The last 30 consecutive total elbow arthroplasties performed by the senior author were reviewed to identify the approach used and pathology treated. Initially, a triceps split and reflection approach was used, then a triceps-preserving approach. Two blinded reviewers measured the component alignment in standardised radiographs. Pearson's correlation coefficient was calculated to investigate inter/intra-observer and error. The two groups were compared using an unpaired Student t-test. Results There were 13 elbows in the triceps-off group and 17 in the triceps-on group. Pearson's coefficient was 0.75 for interobserver error, 0.89 for intra-observer error. There was no statistical difference between the achieved alignment. All ulna components were flexed with a mean angle deviation of 4.5 degrees in the triceps-off group and 5.7 degrees in the triceps on. Two (15%) ulna components in the triceps-off group were placed in over 5 degrees of flexion, compared with seven (44%) in the triceps-on group. Conclusion These results demonstrate no statistical difference in the achieved alignment between the two groups. Surgeons should beware of the tendency to place the ulna component in a flexed position, especially in the triceps-on approach.

Abstract
AIMS Positive ulnar variance is an established risk factor for idiopathic ulnar impaction syndrome (UIS). However, not all patients with positive ulnar variance develop symptomatic UIS and other factors, including the morphology of the lunate, may be involved. The aim of this study was to clarify the relationship between lunate morphology and idiopathic UIS. PATIENTS AND METHODS A cohort of 95 patients with idiopathic UIS (UIS group) was compared with 95 asymptomatic controls with positive ulnar variance. The shape of the lunate was measured using the capitate-triquetrum distance (CTD), ulnar coverage ratio (UCR), radiolunate distance and radiolunate angle. The association of radiographic parameters and lunate types with the development of UIS was investigated in univariable and multivariable analyses. Receiver operating characteristic curves were used to estimate a cutoff for any statistically significant variables. RESULTS The proportion of type II lunates, which have a medial hamate facet, were significantly higher in the UIS group than in the control group in the univariable analysis (p = 0.001). CTD (odds ratio (OR) 1.52; 95% confidence interval (CI) 1.11 to 2.06; p = 0.008) and UCR (OR 44.78; 95% CI 5.35 to 374.90; p = 0.002) showed a positive association with UIS in the multivariable analysis. Estimated cutoff values were 2.5 mm for the CTD (area under the curve (AUC) = 0.65) and 0.4 for the UCR (AUC = 0.64). CONCLUSION The proportion of type II lunates was greater in the UIS group than in the control group. A large UCR, which represents the broad base of the lunate, was positively associated with the development of idiopathic UIS. Cite this article: Bone Joint J 2017;99-B:1508-14.

Abstract
Total elbow arthroplasty can be a rewarding operation and is becoming increasingly used in the elderly fracture population. Multiple approaches are represented in the literature and deciding on the best approach is difficult. This review discusses approaches and their reported outcomes, aiming to allow surgeons to make an informed choice about which approach to use.

[PMID: 28166703 DOI: 10.1177/2309499016684997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/16/2022] Open
Abstract
We describe a muscle sparing approach in which the triceps is elevated without injuring the muscle or disturbing its insertion. The entire extensor mechanism is preserved in continuity, thus preventing any extensor weakness. This can be used preferentially in cases of non-union intraarticular distal humerus fractures planned for Total Elbow Arthroplasty.
