Surgical and Nonoperative Management of Olecranon Fractures in the Elderly: A Systematic Review and Meta-Analysis

Clinical outcomes of olecranon sled fixation in patients with Mayo type II olecranon fractures

Background

Tension band wiring and plate fixation are common internal fixation methods used for olecranon fractures, but complications and reoperations are common. The purpose of this study is to investigate the clinical outcomes of displaced olecranon fractures treated with olecranon sled internal fixation.

Methods

The data of 39 patients with olecranon fractures treated with olecranon sled in the Department of Traumatology of Beijing Jishuitan Hospital between May 2018 and April 2020 were retrospectively analyzed. There were 17 males and 22 females; the mean age was 44.0 ± 15.8 (range, 18-68 years). Preoperative olecranon fractures were classified according to the Mayo classification: 24 cases were type IIA and 15 cases were type IIB. Elbow range of motion (extension and flexion) and forearm rotation (protonation and supination) were observed at the last follow-up. The Mayo elbow performance score (MEPS), Disabilities of the arm, shoulder and hand (DASH) and visual analogue scale (VAS) scores were used to evaluate elbow function and pain, and complications were also recorded.

Results

Thirty-nine patients were followed up for 33.6 ± 8.3 months (range, 25-51 months) after the operation. At the last follow-up, the mean flexion-extension arc was 137° ± 15° (range, 60°-160°), and the mean pronation-supination arc was 178° ± 4° (range, 160°-180°). The mean MEPS was 94.9 ± 9.9 (range, 50.0-100.0). The mean DASH score was 5.4 ± 4.3 (range, 0-18.3). The mean VAS score was 0.4 ± 0.8 (range, 0-3). Seven patients developed olecranon skin irritation, and 3 of them had the internal fixation device removed. Two patients developed heterotopic ossification, of whom 1 patient suffered elbow stiffness.

Conclusion

Olecranon sled internal fixation has good clinical outcomes in the treatment of Mayo type II olecranon fractures with a low rate of reoperations.

Treatment of olecranon fractures in older individuals: a cross-sectional survey of surgeon treatment preferences

Background

With an aging population, the incidence of olecranon fractures in older patients is increasing. The standard of care has traditionally included operative management for displaced fractures. Recent literature has called this standard of care into question. Older patients may be at increased risk of operative complications and may have satisfactory functional outcomes with nonoperative management. Given recently evolving evidence, the current treatment preferences of orthopedic surgeons for older patients with displaced olecranon fractures are unknown.

Methods

We administered a cross-sectional survey of Canadian orthopedic surgeons via e-mail invitation and online survey form to determine treatment preferences for patients aged 65-75 and >75 years with simple displaced and comminuted displaced stable olecranon fractures. Respondents reviewed representative images and were asked to indicate their preferred treatment based on patient age. We also asked respondents to indicate their perceived importance of 11 patient factors on treatment decision-making.

Results

We received 200 responses (33.8% response rate). For patients aged 65-75 years with simple displaced fractures, surgeons preferred tension-band wiring (n = 110, 56%) to plating (n = 82, 42%, P = .005), while only 3% (n = 5) preferred nonoperative treatment. For patients aged >75 years with simple displaced fractures, surgeons preferred operative (n = 144, 73%) to nonoperative management (n = 51, 26%; P < .01) with either tension-band wiring (n = 77, 39%) or plating (n = 67, 34%). In these patients, early range of motion (n = 35, 18%) was preferred to immobilization (n = 16, 8%; P = .004). For comminuted fractures, plate fixation was preferred for patients aged 65-75 years (n = 189, 95%) and >75 years (n = 131, 68%). In patients aged >75 years, this was followed by early range of motion (n = 35, 18%) and immobilization (n = 24, 13%). Of the 11 factors surveyed, participation in high-intensity activities (mean rank = 9.4), independent living (mean rank = 8.8), and disrupted extensor mechanism (mean rank = 8.3) were ranked most highly for increasing likelihood of surgical treatment.

Conclusion

In patients aged 65 to 75 years, operative management is favored by most surgeons, with tension-band wiring preferred over plating for simple displaced fractures. In patients aged >75 years, operative management is again preferred by most respondents for simple and comminuted fractures. Despite operative preferences, there is a paucity of quality evidence to guide treatment decision-making, particularly in patients aged >75 years.

Olecranon fractures : current treatment concepts

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.Cite this article: Bone Joint J 2023;105-B(2):112-123.

Olecranon Fractures: A Critical Analysis Review

»

Olecranon fractures account for 10% of all elbow fractures and are more likely to result from a low-energy injury. A displaced fracture with a stable ulnohumeral joint (Mayo type 2) is the most common type of injury.

»

The management of an isolated olecranon fracture is based on patient factors (age, functional demand, and if medically fit to undergo surgery) and fracture characteristics including displacement, fragmentation, and elbow stability.

»

Nonoperative management can be successfully used in undisplaced fractures (Mayo type 1) and in displaced fractures (Mayo type 2) in frail patients with lower functional demands.

»

Patients with displaced olecranon fractures with a stable ulnohumeral joint without significant articular surface fragmentation (Mayo type 2A) can be managed with tension band wiring, plate osteosynthesis (PO), intramedullary fixation, or suture repair.

»

PO is advocated for multifragmentary fractures and fractures that are associated with ulnohumeral instability. It is essential to consider the variable anatomy of the proximal ulna during surgery.

Cost minimization analysis of the treatment of olecranon fracture in elderly patients: a retrospective analysis

Background

Operative treatment of olecranon fractures in the elderly can lead to greater complications with similar outcomes to nonoperative treatment. The purpose of this study was to analyze cost differences between operative and nonoperative management of isolated closed olecranon fractures in elderly patients.

Methods

Using a United States Medicare claims database, the authors identified 570 operative and 1,863 nonoperative olecranon fractures between 2005 and 2014. The authors retrospectively determined cost of treatment from the payer perspective for a 1-year period after initial injury, including any surgical procedure, emergency room care, follow-up care, physical therapy, and management of complications.

Results

One year after diagnosis, mean costs per patient were higher for operative treatment (United States dollars [US$]10,694 vs US$2,544). 31.05% of operative cases were associated with a significant complication compared with 4.35% of nonoperative cases. When excluding complications, mean costs per patient were still higher for operative treatment ($7,068 vs $2,320).

Conclusions

These findings show that nonoperative management for olecranon fractures in the elderly population leads to fewer complications and is less costly. Nonoperative management may be a higher-value management option for this patient population. These results will help inform management of olecranon fractures as payers shift toward value-based reimbursement models in which quality of care and cost influence surgical decision making.

Hardware complications and reoperations following precontoured plate fixation of the olecranon: a population-based study

BACKGROUND

Several fixation techniques have been described to treat acute olecranon fractures. Plate fixation is often used because of its superior mechanical properties. The reported rates of reoperation after olecranon plate fixation have been quite heterogeneous. The purpose of this study was to establish an updated reoperation rate based on modern precontoured plate constructs.

METHODS

This retrospective cohort study used population-level administrative data to identify all surgically treated adult patients with olecranon fractures at 4 hospitals in Edmonton, AB, Canada, between 2010 and 2015. Radiographic review was conducted to identify patients who underwent precontoured olecranon plate fixation. Fracture characteristics including Mayo fracture classification and other concomitant upper-extremity injuries were identified. Chart reviews were performed to determine patient characteristics and patients who required reoperation. The primary reason for and type of reoperation were determined.

RESULTS

Six hundred patients were surgically treated for olecranon fractures. Precontoured plate fixation was used in 321 patients. The average age of included patients was 56 years (standard deviation [SD], 19.4 years), and there were 173 female patients (53.9%). Reoperation was required in 90 patients (28%). For 50 patients, implant-related irritation was the primary reason for reoperation, representing 55.6% of the patients who underwent reoperation (50 of 90) and 15.6% of the total cohort (50 of 321). Other reasons for reoperation included hardware failure in 17 patients (5.3%), infection in 9 (2.8%), and contracture in 9 (2.8%). Patients who required reoperation were significantly younger (52.9 years [SD, 18.1 years] vs. 57.7 years [SD, 19.4 years]; P = .048) and had significantly higher rates of type III olecranon fractures (17.8% [16 of 90] vs. 8.2% [19 of 231]; P = .04) and Monteggia fractures (13.3% [12 of 90] vs. 4.8% [11 of 231]; P = .008). A multivariate logistic regression model also demonstrated increased odds ratios (ORs) for overall reoperation in patients with Monteggia fractures (OR, 2.99 [95% confidence interval, 1.25-7.17]; P = .014) and for reoperation due to implant-related irritation in younger patients (OR, 0.98 [95% confidence interval, 0.96-0.996]; P = .018). No discerning factors were identified for the 50 patients who underwent hardware removal for implant-related irritation compared with the whole reoperation group (n = 90).

CONCLUSION

This study found that patients with olecranon fractures treated with precontoured plates experienced a hardware removal rate of 15.6% for implant-related irritation. Patients who sustained more complex fractures, such as Monteggia injuries, demonstrated higher rates of reoperation. Increasing age may be associated with lower rates of reoperation. In patients who required reoperation, there were no identifiable radiographic or clinical characteristics that were associated with implant-related irritation as their primary reason for reoperation.

Cost Assessment of Plating Versus Tension Band Wiring Constructs for Treating Mayo Type 2A Olecranon Fractures

PURPOSE

Tension band wiring (TBW) or plating may be used for fixation with similar clinical outcomes for adults with displaced Mayo 2A olecranon fractures. The primary hypothesis is that total direct costs (TDCs) for surgery are lower for TBW than plating. Our secondary hypothesis is that combined surgical TDCs are lower for TBW even with a 100% rate of subsequent tension band hardware removal and a 0% rate of plate removal.

METHODS

Patients who underwent TBW or plating of an isolated unilateral Mayo 2A olecranon fracture between July 2011 and January 2020 at a single academic medical center were identified. Then, TDC for each surgery on plate fixation, TBW, and hardware removal was obtained and converted to 2020 US dollars using information technology cost tools provided by our institution. Finally, relative TDCs were compared between plate fixation and TBW groups using univariate and multivariable generalized estimating equations with log-link.

RESULTS

Of the 97 included patients, the mean age was 50 ± 21 years, and 48% were female. Tension band wiring and plate fixation were performed on 18% (17/97) and 82% (80/97) of male and female patients, respectively. Demographics were similar between groups, although the finding that plate fixation cost 2.6 times that of TBW within the index surgery was significant in the multivariable model, independent of potential confounders (coefficient 2.55, 95% confidence interval: 2.09-3.10). Additionally, mean TDC remained significantly greater for plate fixation even under the hypothetical situation where 100% TBW were removed, and the plate removal rate was 0% (cost difference 181%).

CONCLUSIONS

Using TBW relative to plate fixation may improve the cost of care for operative Mayo 2A olecranon fractures. Furthermore, this finding was robust to the rate of hardware removal.

Nonoperative treatment of distal humerus fractures in the elderly yields satisfactory functional outcomes and low conversion to delayed surgery: a systematic review

Background

Distal humerus fractures (DHFs) pose a treatment challenge in elderly patients. We sought to systematically review and report the clinical outcomes of the nonoperative approach (eg, "bag of bones") for the treatment of these injuries and the rate of conversion to delayed surgery.

Methods

A comprehensive review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines was conducted. Studies involving outcomes after nonoperative treatment of DHF in patients >65 years of age were included from 1985 to present. Data regarding patient age, DHF type, nonoperative treatment method, complications, conversion to delayed surgery, range of motion, union rate, and surgeon- and patient-reported outcome measures were extracted.

Results

A total of five studies met inclusion criteria (all level IV evidence), yielding a total of 143 patients (mean age: 73.5 years to 87.4 years) with 7.1 months to 55 months of follow-up. The mean Mayo Elbow Performance Index scores were good to excellent across several studies (range 83-93.1). Multiple studies reported good range of motion (mean arc of motion: 81 to 106 degrees) and low levels of upper extremity disability (mean Quick Disability of the Arm-Shoulder-Hand scores: 31.3 to 38.5) at the final follow-up. The rate of conversion to total elbow arthroplasty and operative fixation ranged from 0% to 7.5% and 0% to 5%, respectively.

Conclusion

Nonoperative management of distal humerus fractures in the elderly seems to be associated with acceptable functional outcomes and low rates of delayed surgery. This information is important for patient counseling and treatment decision-making.

Scandinavian Olecranon Research in the Elderly (SCORE): protocol for a non-inferiority, randomised, controlled, multicentre trial comparing operative and conservative treatment of olecranon fractures in the elderly

INTRODUCTION

The incidence of olecranon fractures is growing in the elderly population. The traditional operative approach is giving way among the elderly to conservative treatment, which seems to provide a comparable functional outcome with a lower complication burden. However, there is still a lack of reliable evidence to support this shift.The objective of this trial is to investigate whether conservative treatment of displaced olecranon fractures in patients aged 75 or older yields comparable results to those of operative treatment in terms of pain and daily function.

METHODS AND ANALYSIS

Scandinavian Olecranon Research in the Elderly (SCORE) is a randomised, controlled, multicentre, non-inferiority trial. Eligible patients will be randomised to either conservative or operative treatment. The sample size will be 68 patients and allocation done at a 1:1 ratio (34 patients per group). The randomisation is stratified according to the participating hospital and patient's sex. Both groups will receive the same postoperative physiotherapy and pain management. The primary outcome is Disabilities of the Arm, Shoulder and Hand at 1-year follow-up. Secondary outcomes are pain and satisfaction measured on visual analogue scales, Patient Reported Elbow Evaluation, range of motion of the elbow and extension strength of the elbow compared with the unaffected arm. Radiographs will be taken at each follow-up. Primary analysis of the results will be conducted on an intention-to-treat basis.

ETHICS AND DISSEMINATION

The study protocol for this clinical trial has been approved by the Ethics Committee of the Hospital District of Southwest Finland and will be submitted for approval to the Regional Ethics Committees in Linköping, Sweden and Copenhagen, Denmark. Every recruiting centre will apply local research approvals. The results of this study will be submitted for publication in peer-reviewed journals.

Olecranon Fracture in an Older Adult Treated With Locking Plate Osteosynthesis

Although olecranon fractures are not uncommon in the geriatric population, there has been a considerable difference of opinion between surgical and nonsurgical treatments. Surgical treatment is usually deferred in the elderly, even for displaced olecranon fractures, because of inherent risks associated with poor bone quality and soft tissues, which often necessitate further surgeries. However, nonoperative treatment frequently results in an inability to regain full extension strength of the elbow, which can be disabling in select older adults with higher functional demands. We present an active older adult with a displaced olecranon fracture, who achieved a satisfactory result after open reduction and internal fixation (ORIF) using a low-profile locking plate.

Complications and reoperations related to tension band wiring and plate osteosynthesis of olecranon fractures

BACKGROUND

Olecranon fractures are common and usually treated operatively either by tension band wiring (TBW) or plate fixation (PF). The aim of this study was to assess early complications and reoperations and their predictive factors related to those operative methods.

METHODS

A retrospective analysis of all patients with an operatively treated olecranon fracture between 2007 and 2017 at Turku University hospital was performed. Reoperations, postoperative complications, and potential risk factors for these were recorded.

RESULTS

A total of 434 patients (387 TBW and 47 PF) were identified. There was no statistically significant difference in the rate of early complications (49% vs. 62%, P = .262) or reoperations (38% vs. 53%, P = .079) between patients treated with TBW and PF. In the TBW group, the intramedullary placement of Kirschner (K)-wires predisposed patients to complications compared to transcortical placement of the K-wires according to multivariate analysis (odds ratio [OR] 1.94, P = .026). Younger age was associated with the frequency of reoperations, the odds decreasing 24% for every 10 years of age (P < .001). Further, patients with high-energy trauma mechanisms were reoperated more often compared to patients with low-energy trauma (OR 2.99, P = .002). Also, excellent postoperative reduction was associated with higher reoperation rate than good or fair reduction (OR 0.48, P = .033).

CONCLUSION

There is a high risk of early complications and reoperations associated to both TBW and PF. Transcortical positioning of K-wires may reduce the rate of complications in TBW.

Epidemiology, classification and treatment of olecranon fractures in adults: an observational study on 2462 fractures from the Swedish Fracture Register

Purpose

This nationwide study aims to describe the epidemiology, fracture classification and current treatment regimens of olecranon fractures in adults.

Methods

We performed a descriptive study based on registered data from the Swedish Fracture Register (SFR). All non-pathological olecranon fractures reported between 1 January 2014 and 31 December 2018 in patients aged ≥ 18 years were included. Data on age, sex, injury mechanism, fracture classification (according to the modified Mayo classification system), primary treatment and seasonal variation were analyzed. We compared patients < 65 with those > 65 years regarding injury mechanism, distribution of fracture types and subsequent treatment.

Results

In total, 2462 olecranon fractures were identified in the SFR. Median age was 66 years and 65% were women. Of all fractures, 303 (12%) were proximal avulsion, 1044 (42%) simple central, 717 (29%) comminuted central and 398 (16%) distal olecranon fractures. Nonoperative treatment was performed in 21% of the patients < 65 and 35% of the patients > 65 years. Tension band wiring was used for most simple central fractures. Plate fixation was used in almost half of the operatively treated fractures classified as unstable comminuted central and distal olecranon fractures. Men show a higher proportion of high-energy trauma than women in both age groups.

Conclusion

Isolated fractures of the olecranon occur after a low-energy trauma, especially in older women (> 65 years). Non-operative treatment is common in uncomplicated fractures and operative treatment in more complex fractures nationwide. A shift to plate fixation in the more unstable fracture patterns is observed. These results may help health care providers and clinicians gain a better understanding of isolated olecranon fractures.

Proximal ulna fractures in adults: A review of diagnosis and management

Proximal ulna fractures are relatively common upper limb injuries, which may represent fragility fractures or result from high-energy trauma. These include fractures of the olecranon, coronoid and associated radial head dislocations. A wide variety of treatment options are available for the management of these injuries that makes the selection of most appropriate treatment difficult. We aim to provide a brief overview of the treatment options for such injuries.

Locked plating of geriatric olecranon fractures leads to low fixation failure and acceptable complication rates

Hypothesis

The purpose of this study was to report the rate of major complications in patients with geriatric olecranon fractures managed operatively with a locking plate. Secondary objectives included minor complications, as well as pain and range of motion at the final follow-up. We hypothesized that these patients have a low rate of complications as well as low pain and satisfactory elbow range of motion at the final follow-up.

Materials and Methods

A retrospective review of isolated geriatric olecranon fractures presenting from 2006 to 2019 was performed at a single level I trauma center. Inclusion criteria were ≥75 years of age, operative management with a locking plate, and clinic follow-up at least until evidence of radiographic union or a major complication. Exclusion criteria included nonoperative management, insufficient follow-up, and absence of locking plate in surgical technique. Variables examined included demographic information, Charleston comorbidity index, American Society of Anesthesiologists score, living independence, gait assistance, mechanism of injury, open vs. closed fracture, Mayo radiographic classification, Arbeitsgemeinschaft für Osteosynthesefragen classification, time to surgery, implant type, presence of triceps offloading suture, length of postoperative immobilization, date of radiographic union, range of motion at the final follow-up, pain visual analog scale score at the final follow-up, major and minor complications, and return to the operative room. A major complication was defined as a return to the operative room for deep infection or loss of fixation (displacement of fracture >5 mm). A minor complication was defined as any other complication.

Results

A total of 65 patients ≥75 years of age with olecranon fractures were identified. Of these, 36 patients met inclusion criteria with an average follow-up of 23 weeks (range 5-207). The mean length of immobilization was 13 days (range 0-29 days). Thirty-two of 36 (88.8%) patients achieved radiographic evidence of union at an average of 8.9 weeks (range 5.3-24.1 weeks). There were 4 remaining patients who underwent secondary intervention before primary union representing an 11.1% major complication rate including 2 deep infections (5.6%) and 3 failures of fixation (8.3%). There were 7 minor complications in 5 of 36 (13.9%) patients. At the final follow-up, the average visual analog scale score was 2.6 (range 0-6), the average elbow arc of motion was 120° (range 70-147°), and mean pronation/supination was 85°/84° (range 45-90°/45-90°).

Conclusion

Geriatric olecranon fractures are a challenging orthopedic problem with remaining controversy regarding ideal treatment. Despite advancement in geriatric fracture care, there is scant literature on the outcomes of locked plating technology in geriatric olecranon fractures. This study supports use of operative anatomic fixation with precontoured locked plates and early mobilization with an acceptable failure rate.
