[PMID: 38693300 PMCID: PMC11063218 DOI: 10.1038/s41598-024-60264-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Accepted: 04/21/2024] [Indexed: 05/03/2024] Open
Abstract
Although tension band wiring (TBW) is popular and recommended by the AO group, the high rate of complications such as skin irritation and migration of the K-wires cannot be ignored. Ding's screw tension band wiring (DSTBW) is a new TBW technique that has shown positive results in the treatment of other fracture types. The objective of this study was to evaluate the stability of DSTBW in the treatment of olecranon fractures by biomechanical testing. We conducted a Synbone biomechanical model by using three fixation methods: DSTBW, intramedullary screw and tension band wiring (IM-TBW), and K-wire TBW, were simulated to fix the olecranon fractures. We compared the mechanical stability of DSTBW, IM-TBW, and TBW in the Mayo Type IIA olecranon fracture Synbone model using a single cycle loading to failure protocol or pullout force. During biomechanical testing, the average fracture gap measurements were recorded at varying flexion angles in three different groups: TBW, IM-TBW, and DSTBW. The TBW group exhibited measurements of 0.982 mm, 0.380 mm, 0.613 mm, and 1.285 mm at flexion angles of 0°, 30°, 60°, and 90° respectively. The IM-TBW group displayed average fracture gap measurements of 0.953 mm, 0.366 mm, 0.588 mm, and 1.240 mm at each of the corresponding flexion angles. The DSTBW group showed average fracture gap measurements of 0.933 mm, 0.358 mm, 0.543 mm, and 1.106 mm at the same flexion angles. No specimen failed in each group during the cyclic loading phase. Compared with the IM-TBW and TBW groups, the DSTBW group showed significant differences in 60° and 90° flexion angles. The mean maximum failure load was 1229.1 ± 110.0 N in the DSTBW group, 990.3 ± 40.7 N in the IM-TBW group, and 833.1 ± 68.7 N in the TBW group. There was significant difference between each groups (p < 0.001).The average maximum pullout strength for TBW was measured at 57.6 ± 5.1 N, 480.3 ± 39.5 N for IM-TBW, and 1324.0 ± 43.8 N for DSTBW. The difference between maximum pullout strength of both methods was significant to p < 0.0001. DSTBW fixation provides more stability than IM-TBW and TBW fixation models for olecranon fractures.

[PMID: 38283407 PMCID: PMC10810729 DOI: 10.1093/jscr/rjae016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 01/10/2024] [Indexed: 01/30/2024] Open
Abstract
This case report describes the intricate aspects of managing pediatric lower limb trauma. A 7-year-old patient had a severe compound fracture and significant soft tissue damage in the left lower limb, classified as Gustilo Grade IIIC. This necessitated the use of scoring systems such as the Mangled Extremity Severity Score and limb salvage index to assess the likelihood of limb preservation. Despite these high amputation risk indicators, a multidisciplinary approach has led to limb salvage surgery with internal fixation. Detailed postoperative monitoring revealed progressive recovery culminating in restored sensation, bone healing, and functional recovery. The discussion emphasizes the difficulties in deciding between limb salvage and amputation, stressing the importance of tailored care and cautious scoring system interpretation in pediatric cases. This conclusion advocates the prioritization of limb salvage in children owing to their unique healing capabilities while highlighting the need for further research to refine treatment protocols for pediatric lower limb trauma.

Abstract
PURPOSE This study aimed to compare the biomechanical pull-out strength of the three different tension band wiring (TBW) methods employed to fix transverse olecranon fractures on bone models. METHODS Three different fixation models were created in groups of seven synthetic olecranon fractured bone models. The first technique was fixed the olecranon with the traditional TBW method. The second technique was fixed the olecranon with a large intramedullary screw TBW method. The third technique was fixed the olecranon with the double-screw TBW method. The pull-out force needed for the failure of each specimen under the tensile test device was evaluated, and the results were recorded. RESULTS We found that the lowest average pull out strength was 55.10 N (range: 35.87-65.85 ± 10.17) in the traditional TBW method, the highest pull out strength was 84.28 N (range: 63.67-117 ± 18.87) in the double-screw TBW method. The pull out strength was 70.80 N (range: 52.60-80.95 ± 10.18) in the intramedullary screw TBW method. In terms of ultimate failure loads, there was no significant difference between the intramedullary screw TBW and the double-screw TBW (p > .05) while there was a significant difference between the traditional TBW and the other two methods (p < .05). CONCLUSION The use of screw(s) shows higher biomechanical stability than K-wires in the TBW method. Double-screws fixation gives similar results in terms of the biomechanical load to failure compared to a large intramedullary screw fixation. Both screw methods can be used as stable constructs in clinical practice. LEVEL OF EVIDENCE III, biomechanical trial.

[PMID: 37488540 PMCID: PMC10364372 DOI: 10.1186/s12891-023-06684-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Accepted: 07/01/2023] [Indexed: 07/26/2023] Open
Abstract
BACKGROUND Tension band wiring (TBW) is a common surgical intervention for olecranon fractures. However, high rate of complications such as loss of reduction, skin irritation, and migration of the K-wires were reported up to 80%. Ding's screw tension band wiring (DSTBW) is a new TBW technique that has shown positive results in the treatment of other fracture types. The objective of this study was to evaluate the stability of DSTBW in the treatment of olecranon fractures by finite element analysis. METHOD We used Ding's screw tension band fixation (DSTBW) and K-wire tension band fixation (TBW) to establish a finite element model to simulate and fix olecranon fractures. The stress distribution, opening angle, twisting angle, and pullout strength of K-wires or screws were analyzed and compared. RESULTS The maximum von Mises stress was observed on the internal fixation for 90° elbow motion in both groups. The von Mises value of the screw in DSTBW was 241.2 MPa, and the von Mises value of k-wire in TBW was 405.0 MPa. Opening angle: TBW was 0.730° and DSTBW was 0.741° at 45° flexion; TBW was 0.679° and DSTBW was 0.693° at 90° flexion. Twisting angle: TBW was 0.146° and DSTBW was 0.180° at 45° flexion; TBW was 0.111° and DSTBW was 0.134° at 90° flexion. The pullout strength of DSTBW was significantly higher than that of TBW. Maximum pullout strength of Ding's screw was 2179.1 N, maximum pullout strength of K-wire was 263.6 N. CONCLUSION DSTBW technology provides stable fixation for olecranon fractures, reducing the risk of internal fixation migration and failure.

Abstract
PURPOSE 3D printing techniques guide precision medicine and show great development potential in clinical applications. The purpose of this study was to compare the clinical outcomes of 3D-printed navigation templates versus free-hand in tension band wiring (TBW) procedures for olecranon fractures. METHODS Patients who underwent TBW due to Mayo type II olecranon fractures between January 2019 and December 2021 in our hospital were prospectively enrolled in the study. The patients were divided into the 3D printed navigation template guiding TBW group (3D printed group) and the free-hand TBW group (free-hand group). The primary endpoint of this study was the success rate of the bicortical placement of Kirschner wires (K-wires). Times of intraoperative fluoroscopy, operation times, complications, VAS scores, and Mayo Elbow Performance Scores (MEPS) were analyzed as the secondary outcomes measure. RESULTS The success rate of the bicortical placement of K-wires was 85.7% in the 3D Printed group was significantly higher than the free-hand group (60%). There were fewer times of intraoperative fluoroscopy in the 3D Printed group (1.43 ± 0.51) than that in the free-hand group (2.60 ± 1.00) with statistical significance (P < 0.05). At the date of the last follow-up, four patients suffer from pain and skin injury at the K-wires insertion site in the 3D Printed group and 14 patients in the free-hand group, a significant difference between the two groups (P < 0.05). No statistically significant differences were found in operation time, VAS scores, and MEPS between the two groups. CONCLUSIONS The individualized 3D-printed navigation template-assisted TBW demonstrated good accuracy and resulted in reduced times of intraoperative fluoroscopy and complication compared to the free-hand TBW for olecranon fractures.

Abstract
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.

Abstract
Although tension band wiring is effective for treating olecranon fractures, it is associated with a high reoperation rate because of hardware-related problems. The loop anchor tension band technique is a novel modification of the Arbeitsgemeinschaft für Osteosynthesefragen (AO)-modified tension band wiring technique. This technique is suitable for treating olecranon fractures without severe comminution and olecranon osteotomy. In the current case series, 2 intramedullary 1.25-mm Kirschner wires (K wires) were inserted as temporary fixation into the ulnar shaft from the olecranon after anatomical reduction. The proximal end of each K-wire was bent into a loop shape and advanced deep into the triceps tendon. A transverse hole was drilled distal to the fracture site, and a 1.0-mm metal wire was passed through the bone tunnel and the loops. The wire was tightened to form a figure-of-eight tension band construct. In total, 10 patients with a mean age of 49 (range: 19 to 85) years were included in this pilot series. The mean and minimum follow-up periods were 13.9 and 12 months, respectively. All fractures achieved favorable union, both radiographically and clinically. The mean QuickDASH score was 15.4 (range: 13.6 to 18.2) and the mean Mayo elbow performance score was 94 (range: 85 to 100). None of the patients experienced K-wire migration. The loop anchor tension band technique is a simple, cost effective modification of conventional tension band wiring and exhibited no implant migration in a pilot series.

[PMID: 34563734 DOI: 10.1016/j.otsr.2021.103076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 05/16/2021] [Accepted: 07/16/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND Tension-band wiring (TBW) and plate fixation are commonly used to fix displaced olecranon fractures. However, the high incidence of complications in the elderly, such as wound breakdown, infection, and loss of reduction, remain a concern for orthopaedic surgeons. Furthermore, patients frequently suffer from removal of the hardware. Even so, the operation seems to be indicated for independent elderly patients to return to their former activities of daily living. HYPOTHESIS TBW of displaced stable olecranon fractures with Eyelet-pins in the independent elderly reduce the incidence of complications and allow early elbow joint exercise to keep their former activities. PATIENTS AND METHODS We operated on the displaced stable olecranon fractures of 17 independent patients aged ≥ 70 using TBW with two Eyelet-pins. Eyelet-pins have an eyelet at the trailing end to prevent pin migration by passing a soft wire through it. The patients were reviewed clinically and radiologically at 2, 6, 12, and 24 weeks, and clinically at 1 year after the surgery. RESULTS All fractures were united within 12 weeks, and the anatomic reduction was maintained. Mean radiographic proximal migration of the Eyelet-pins was 0.4mm (0.1 ∼ 1.2mm). Mean active elbow flexion was 136° (115° ∼ 145°) and extension 6.2° (0° ∼ 30°). Two patients had mild local pain and pain on motion at the tip of the eyelet. No patient required removal of the hardware. Other complications, such as superficial or deep wound infections, and neurological symptoms or signs, were not seen. All patients were able to maintain their former activities of daily living. CONCLUSION TBW with Eyelet-pins for displaced stable olecranon fractures is useful for independent elderly patients to reduce the incidence of complications and to maintain their former activities of daily living without removal of the hardware.

Abstract
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.

Abstract
Background High rates of secondary surgery after fixation of olecranon fractures have been reported. Identification of risk factors can aid surgeons to reduce complications leading to additional surgical procedures. Methods Olecranon fractures treated at seven hospitals from 2007 to 2017 were identified, and the radiographs were classified. Isolated, displaced olecranon fractures treated operatively with tension band wiring (TBW) or precontoured plate fixation (PF) were reviewed. Adjusted risk factors for secondary surgery were analyzed, and a multivariable predictive model for secondary surgery was built. Results After the initial review of 1259 olecranon fractures, 800 isolated, displaced olecranon fractures met the inclusion and exclusion criteria. The distribution of two-part and multifragmented fractures was equal. TBW was used in 636 patients and PF in 164 patients. Multifragmentation was a significant variable influencing preference for PF. Secondary surgery was performed in 41% patients and symptomatic hardware removal was the most frequent primary indication. In both the TBW and PF group, the rates of major complications leading to secondary surgery were 13% (P = .96). The adjusted risk of secondary surgery was lower with increasing age (odds ratio by 10 years increments, 0.74; 95% confidence interval, 0.68-0.80, P < .01). Compared with PF, TBW with transcortical K-wires (odds ratio, 2.06; 95% confidence interval, 1.36-3.14; P < .01) and TBW with intramedullary K-wires (odds ratio, 4.32; 95% confidence interval, 2.16-8.86, P < .01) had significantly higher adjusted risk of secondary surgery. Conclusion Surgeons preferred to use PF in younger patients and multifragmented fractures. Patients should be counseled that secondary surgery is common after surgical fixation of olecranon fractures. Symptomatic hardware removal was the most frequently reported reason for secondary surgery and more frequent after TBW. When using TBW, intramedullary K-wire positioning should be avoided. The rate of major complications leading to secondary surgery was similar in the TBW and PF groups. Overall, the risk of subsequent secondary surgery was higher in younger patients and patients treated with TBW.

Civan O, Ugur L, Yildiz G. Comparison of two surgical techniques for the treatment of transverse olecranon fractures: A finite element study. Int J Med Robot 2021; 17:e2265. [PMID: 33855772 DOI: 10.1002/rcs.2265] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 01/31/2021] [Accepted: 04/13/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND In this study, we aimed to compare the stability of traditional tension band wiring (TBW) and screw combined TBW (SC-TBW) fixation methods performed for a transverse olecranon osteotomy-fracture during different degrees of elbow movement by using finite element analysis. METHODS Three-dimensional solid modeling of the olecranon was obtained by computed tomography images. Transverse olecranon fracture was created and fixed by TBW and SC-TBW with respect to triceps muscle force. Opening angle, twisting angle and interplanar translation occurring on the fracture line were evaluated at 45° and 90° elbow flexion. RESULTS Opening angle: 0.71°, 0.87° at 45° and 0.64°, 0.67° at 90° elbow flexion for TBW and SC-TBW, respectively. Twisting angle: -0.01°, -0.19° at 45° flexion and 0.19°, 0.30° at 90° flexion for TBW and SC-TBW, respectively. Interplanar translation: 1.93 mm, 4.65 mm at 45° flexion and 1.78 mm, 3.95 mm at 90° flexion for TBW and SC-TBW, respectively. CONCLUSION TBW fixation provides more stability than SC-TBW fixation model.

Abstract
Olecranon osteotomy allows for improved visualization of the distal humeral articular surface. This study compared the clinical outcomes of 2 methods of olecranon repair following olecranon osteotomy as part of distal humerus fracture repair. This was a retrospective review of distal humerus fractures treated via a transolecranon approach during a 9-year period. In each case, the olecranon osteotomy was fixed with either tension band wiring (TBW) or plate fixation (PF). Patient demographics, injury information, and surgical management were recorded. Measured outcomes included elbow motion, time to osteotomy union, and postoperative complications. Mayo Elbow Performance Index (MEPI) scores were obtained for all patients. Forty-eight patients were included. All patients had intra-articular AO type 13-C2 or 13-C3 distal humerus fractures and underwent open reduction and internal fixation (ORIF) with olecranon osteotomy. Mean documented follow-up was 20.5 months. Twenty-seven patients had fixation of the olecranon osteotomy with TBW, and 21 with PF. Clinically, there were no differences in osteotomy time to union, elbow motion, or MEPI score at final follow-up. However, patients fixed with TBW had greater elbow extension at both 6-month and final follow-up. Complication rates did not differ. Patients undergoing TBW or PF for repair of an olecranon osteotomy following ORIF of intra-articular distal humerus fractures have similar outcomes. Patients undergoing osteotomy PF may experience less terminal elbow extension when compared with those fixed with TBW. Given their similar clinical outcomes, either modality may be considered when selecting a construct for olecranon osteotomy repair as part of comminuted distal humerus fracture repair.

Olecranon fractures: do they lead to osteoarthritis? Long-term outcomes and complications. INTERNATIONAL ORTHOPAEDICS 2020; 44:2379-2384. [PMID: 32647967 DOI: 10.1007/s00264-020-04695-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Accepted: 06/29/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To report radiologic, functional outcomes, and complications with a long-term follow-up in acute olecranon fractures treated with osteosynthesis and, secondly, to determine the predisposing factors to arthritis. METHODS Forty-two patients treated with osteosynthesis for acute olecranon fractures were reviewed, with a minimum follow-up of 24 months. Radiological and clinical evaluations including DASH, MEPS, active range of motion, pain, arthritis, associated lesions, and complications were recorded. Arthritis was classified according to Broberg-Morrey scale. A logistic regression model was estimated to determine risk factors to develop ulnohumeral arthritis. The association between the types of fractures according to Mayo classification and MEPS, and the association between the type of fracture and the presence of pain were analyzed. RESULTS The average follow-up was of 43.64 months. The flexion-extension average range was 135.6°, and the mean MEPS was 89.45; the DASH was 25.26. Eighteen cases (42.86%) were fixed with pre-contoured locking plates, 21 with tension band wiring (50%), and 3 with cannulated screws of 7 mm (7.14%). Six cases (14.29%) needed hardware removal. All fractures healed. Ulnohumeral osteoarthritis was observed in 14 cases (33.3%). We did not find a significant association among the MEPS, pain, and the fracture type, according to Mayo (p > 0.1 for both values). A significant association was found (p < 0.05) between fracture type and the osteoarthritis. CONCLUSIONS In olecranon fractures, good functional and radiological results with low complications are predictable. The osteoarthritis is possible in more complex fractures and with other associated fractures.

Abstract
OBJECTIVES To compare clinically important mechanical properties of three techniques used to fix transverse olecranon fractures (Arbeitsgemeinschaft fur Osteosynthesefragen and Orthopaedic Trauma Association class 2U1B1): (1) intramedullary (IM) screw, (2) locking plate, and (3) tension band wire in a realistic loading protocol using a cadaveric model. METHODS Fresh frozen cadaveric transverse olecranon fracture models were fixed with an IM screw (n = 6), a locking plate (n = 6), or a tension band (n = 6). Compression after fixation was recorded using a pressure sensor in the fracture before samples were loaded through the triceps tendon for 500 cycles of 0-500 N, assessing implant survival. The primary outcome measure was compression force before loading. The secondary outcome was frequency of implant failure defined as breakage of the implant itself or fracture gapping >5 mm. Binary outcomes were compared with χ2, and continuous variables were compared with unadjusted analysis of variance and a multivariable regression model adjusting for age, sex, dual-energy X-ray absorptiometry T-score, and testing order. RESULTS No statistically significant difference was shown in fracture compression between IM screw (mean, 162 N; 95% confidence interval [CI], 27-297 N), locking plate (mean, 125 N; 95% CI, -9-260 N), and tension band (mean, 163 N; 95% CI, 29-298 N) in unadjusted (p = 0.89) and adjusted (p = 0.82) analyses. A 100% implant failure rate was observed with tension band compared with 0% implant failure with IM screw or locking plate (p < 0.01). CONCLUSION We found no statistically significant differences in compression across the fracture site among techniques. We did find a higher risk of implant failure with tension band compared with IM screw and locking plate during cyclic loading in cadaveric bone.

Advantages of expulsion-proof pins in the treatment of olecranon fractures with tension band wiring: Comparison with a control group. Orthop Traumatol Surg Res 2019; 105:1593-1599.

Abstract
INTRODUCTION Tension band wiring is considered the standard treatment for transverse olecranon fractures. Its main complications are pin migration and discomfort caused by the hardware. We have designed and used "expulsion-proof" pins (EPP) that are shaped to prevent migration and reduce discomfort. This study compared the complication rate between our device and Kirschner pins (controls). HYPOTHESIS We hypothesised that EPP would have lower migration rates and fewer complications than standard Kirschner pins. MATERIALS AND METHODS This retrospective, single-center, multi-operator, observational, study examined data from January 1996 to December 2014. The primary outcome was the occurrence of pin migration. Secondary outcomes were the occurrence of one or more additional complications and the hardware removal rate. RESULTS The study enrolled 101 patients: 53 (52.4%) with expulsion-proof pins and 48 (47.6%) controls. The mean follow-up was 240.6days in the EPP group and 268.9days in the control group. No cases of migration (0%) were found in the EPP group versus 21 (43.7%) cases in the controls (p<0.05). One or more complications occurred in 18 (33.9%) patients in the EPP group versus 46 (95.8%) controls (p<0.05). There was material discomfort in 13 (24.5%) cases and 1 (1.9%) case of secondary displacement in the EPP group, compared with 38 (79.2%) and 7 (14.6%) cases, respectively, in the controls (p<0.05). The rate of delayed consolidation was statistically identical in the two groups (p=0.103). The hardware was removed in 13 (24.5%) cases in the EPP group compared with 36 (75%) controls (p<0.05). CONCLUSION EPPs are useful for management of olecranon fractures treated via TBW: the pins do not migrate and can reduce complications, discomfort, secondary displacement, and the hardware removal rate. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
OBJECTIVE To determine the influence of wiring configurations on initial tension and resistance to tensile loads in tension band constructs without the contributions of Kirschner-wire stabilization. STUDY DESIGN Experimental study. SAMPLE POPULATION A solid brass femur model manufactured on the basis of computed tomography of a normal right femur of a 30-kg dog modified by transection of the greater trochanter and placement of two pins that did not cross the simulated osteotomy. METHODS Four tension band configurations were applied to the metal trochanteric osteotomy model: figure-of-eight with one twist (OT), figure-of-eight with two twists (TT), dual interlocking single loop, and double loop (DL). Configurations were tested under both monotonic loading (n = 8 per configuration) and incremental cyclic loading (n = 8 per configuration). Initial tension after tying, residual tension remaining after each cycle, and failure load at 2 mm of displacement (considered equivalent to clinical failure) were compared between configurations. RESULTS The initial tension and the load to 2 mm of displacement were lower for OT wires compared with TT wires. The DL was the strongest and most stable configuration, generating 2.3 to 3.5 times greater initial tension, maintaining a greater percentage of residual tension under incremental cyclic loads, and resisting 2.0 to 2.4 times greater load before failure at 2 mm. Failure load was highly correlated with initial tension. CONCLUSION Wire configurations reaching greater initial tension, such as the DL, allowed constructs to resist higher tensile loads. CLINICAL IMPACT Wire configurations allowing higher initial tension may be warranted when tension bands are expected to sustain high tensile loads.

Abstract
Olecranon fractures are common upper-extremity fractures amenable to various surgical techniques. The authors conducted a systematic review and meta-analysis to evaluate surgical management strategies for olecranon fractures in adult patients. Two investigators independently screened articles from records obtained from MEDLINE, Embase, SPORTDiscus, CINAHL, and the Cochrane Library databases. The authors compared tension-band wiring (TBW) with plate fixation (PF) for the outcomes of complications and hardware removal. Subgroup analyses were conducted comparing randomized controlled trials with observational studies for each outcome. In addition, the authors evaluated novel fixation techniques other than TBW and PF. Twenty-four studies were included in the systematic review and 10 studies were included in the meta-analysis of TBW vs PF. Compared with TBW (n=270), patients who underwent PF (n=369) had a significantly lower complication rate (relative risk, 0.48; 95% confidence interval, 0.36-0.64; P<.01; I2=16%). Plate fixation (41 of 332) also had less hardware removal compared with TBW (79 of 236; relative risk, 0.36; 95% confidence interval, 0.25-0.50; P<.01; I2=0%). Subgroup analyses showed no difference when comparing randomized controlled trials with observational studies for the outcomes of complication rate (P=.45) and hardware removal (P=.54). Qualitative analysis revealed novel methods of olecranon fixation: a modified cable pin system, tension banding through 2 cannulated screws, olecranon memory connector fixation, and cancellous screw TBW. This meta-analysis revealed significantly lower complication and hardware removal rates for PF compared with TBW. Several novel methods of olecranon fixation may represent viable alternatives.

Abstract
BACKGROUND Displaced transverse fractures of the body of the patella are usually associated with disruption of extensor mechanism and should be fixed surgically. The most common method is a tension band wiring (TBW) technique. Some surgeons concurrently employ an augmented circumferential cerclage wiring (ACCW) technique to help fracture stabilization and aid in fracture healing; however, its role and effect on the treatment outcomes is unclear. METHODS We performed a STROBE-compliant retrospective observational cohort study on all cases of acute closed patella fracture that were treated at our institution between 2006 and 2012. Of 185 episodes, 72 (38.9%) were eligible for this study according to our inclusion/exclusion criteria. We classified these subjects with AO/OTA type 34-C1.1 or 34-C2 lesions into two groups for analyses: fractures treated with modified TBW and ACCW (group 1, n = 27) and those treated with modified TBW alone (group 2, n = 45). Plain radiographs were used to evaluate radiographic outcomes and the effect of potential risk factors on fixation failure was analyzed by subgroup comparisons. RESULTS Our results revealed that there were no significant differences in the rates of fixation failure (P = 0.620), nonunion (P = 0.620), and revision surgery (P = 0.620) between the groups. Although not statistically significant, there was a trend towards a positive risk association between fixation failure and age distribution > 60 years (10.0% vs. 0.0%, P = 0.124; OR = 8.0, P = 0.168) and > 70 years (9.4% vs. 2.5%, P = 0.321; OR = 4.0, P = 0.237) and the superficial level of the K-wires (12.0% vs. 1.5%, P = 0.117; OR = 6.3, P = 0.121). Regarding those modified TBW patients concurrently treated with an ACCW, the potential risk association between fixation failure and the superficial level of the K-wire was prone to increase further (28.6% vs. 0.0%, P = 0.060; OR = 18.6, P = 0.071). CONCLUSIONS Concurrent application of an ACCW might be needless and not efficacious to help fracture stabilization and healing in patients having been treated with modified TBW for displaced transverse fractures of the body of the patella. Adherence to correct surgical technique such as putting the K-wires at the proper level and securing control of the both ends of the K-wires may be more important and help in improving outcomes.

Abstract
INTRODUCTION Tension band wiring (TBW) used for olecranon fractures is afflicted with a high rate of complications. The aim of this study was to compare the stability of the TBW versus an alternative, novel low-profile olecranon tension plate (OTP) with angular stable screws in a simulated complex fracture model. MATERIALS AND METHODS Nine fresh-frozen pairs of cadaver proximal ulnae with an oblique osteotomy and an additional wedge fragment simulating an unstable fracture were tested. The TBW and OTP were implanted pairwise. The elbow motion was simulated in a single-muscle model and ranged from full extension to 90° of flexion. The pulling force of the triceps tendon ranged from 50 to 200 N. The displacement of the fracture fragments was measured with a video motion analysis system over 304 cycles. Data were assessed statistically using the Wilcoxon signed-rank test. RESULTS The cyclic loading tests showed mean loosening of the fracture fragments at the articular surface of 0.56 mm using TBW (SD 0.65) and 0.15 mm for OTP (SD 0.39). There was no statistical significance in loosening between the two constructs (p = 0.31). No plate breakage or screw loosening occurred. CONCLUSIONS The low-profile OTP, using the principles of pre-tensioning, lag, cortical, and angular stable screws together, demonstrated similar stability after olecranon fracture fixation when compared with the TBW technique and a lag screw in the olecranon fracture model with a third wedge fragment.

Abstract
OBJECTIVE To compare the initial biomechanical properties of olecranon osteotomies stabilized with intramedullary pins and a Nitinol bone staple to osteotomies stabilized with pin and tension band wire fixation. STUDY DESIGN Ex vivo mechanical evaluation on cadaveric bones. MATERIAL AND METHODS Ten pairs of cadaveric forelimbs from skeletally mature Greyhounds with an olecranon osteotomy stabilized with either a pin and Nitinol bone staple or a pin and tension band wire. A single load to failure was applied to each specimen through the triceps tendon. Biomechanical properties were compared based on stiffness, yield load, and maximum load to failure and load at 2 mm of axial displacement. RESULTS Specimens stabilized with the bone staple were biomechanically superior in all the variables tested. There was significantly greater stiffness (118.0 ± 25.9 N/mm versus 70.1 ± 40.4 N/mm; p = 0.005), yield load (319.0 ± 99.8 N versus 238.0 ± 42.5 N; p = 0.03), maximum load sustained (385.0 ± 99.2 N versus 287.0 ± 37.4 N; p = 0.009), and load at 2 mm of axial displacement (218.0 ± 51.5 N versus 138.0 ± 48.7 N; p = 0.002) in specimens stabilized with pins and a Nitinol bone staple than specimens stabilized with pin and tension band wire fixation. CLINICAL SIGNIFICANCE The pin and Nitinol bone staple construct provides a biomechanically superior alternative to pin and tension band wire fixation for stabilization of olecranon osteotomies, and its use warrants further clinical investigation.

Abstract
BACKGROUND Several different surgical techniques are used in the treatment of olecranon fractures. Tension band wiring is one of the most preferred options by surgeons worldwide. The concept of this technique is to transform a tensile force into a compression force that adjoins two surfaces of a fractured bone. Currently, little is known about the resulting compression force within a fracture. OBJECTIVE Sensor devices are needed that directly transduce the compression force into a measurement quality. This allows the comparison of different surgical techniques. Ideally the sensor devices ought to be placed in the gap between the fractured segments. METHODS The design, development and characterization of miniaturized pressure sensors fabricated entirely from polydimethylsiloxane (PDMS) for a placement within a fracture is presented. The pressure sensors presented in this work are tested, calibrated and used in an experimental in vitro study. RESULTS The pressure sensors are highly sensitive with an accuracy of approximately 3 kPa. A flexible fabrication process for various possible applications is described. The first in vitro study shows that using a single-twist or double-twist technique in tension band wiring of the olecranon has no significant effect on the resulting compression forces. CONCLUSIONS The in vitro study shows the feasibility of the proposed measurement technique and the results of a first exemplary study.

Abstract
BACKGROUND Surgery for fixation of olecranon fractures is associated with reoperation, mostly for implant removal. A study of a large cohort of patients treated by many different surgeons allows us to determine if specific techniques or implants are associated with a higher rate of reoperation. QUESTIONS/PURPOSES After open reduction and internal fixation of isolated olecranon fractures, what factors are associated with (1) reoperation and (2) implant removal? METHODS Three hundred ninety-two adult patients who had operative treatment of a displaced olecranon fracture not associated with other fractures, dislocation, or subluxation at two area hospitals between January 2002 and May 2014 were analyzed to determine factors associated with reoperation. One hundred thirty-eight (35%) patients had plate and screw fixation and 254 (65%) tension band wiring. Nearly 100% of patients with displaced olecranon fractures are currently treated operatively at our hospitals. All patients were followed for at least four months. Two hundred three of the 392 (52%) patients were followed for one year or more. Ninety-nine patients (25%) had a second operation, 92 (93%) at least in part for implant removal (12 for wire migration [3% of all fractures, 12% of reoperations]). We considered patient-related, fracture-related, and implant-related endpoints as possible factors associated with reoperation. With a total sample size of 99 reoperations, an α of 0.05, and an effect size of 0.3, we had 87% power. RESULTS Reoperation was less common in men (36 [36%], women: 63 [64%]; adjusted odds ratio, 0.32; 95% confidence interval, 0.18-0.56; p < 0.001) and older patients (adjusted odds ratio, 0.75; 95% confidence interval, 0.65-0.87; p < 0.001). Similarly, request for implant removal was less in men (33 [36%], women: 59 [64%], adjusted odds ratio, 0.31; 95% confidence interval, 0.18-0.56; p < 0.001) and older patients (adjusted odds ratio, 0.75; 95% confidence interval, 0.65-0.87; p < 0.001). CONCLUSIONS Patients who have operative fixation of a fracture of the olecranon can be counseled that most patients keep their implants, that only 3% experience implant migration, and that technical factors such as the type or configuration of an implant seem less important than personal factors in determining who requests a second surgery for implant removal. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
Background Tension-band wiring (TBW) is a well-established fixation technique for two-part, transverse fracture types of the olecranon. However, complication rates up to 80 % are reported. By reporting on the enormous impact on the patient if failed the aim of the present report was to emphasize the importance of correct K wire positioning in TBW. Case presentation We present the case of a 49-year-old woman who suffered from a radioulnar synostosis of the forearm due to malpositioned K wires after TBW treatment. The patient was treated by heterotopic bone resection supported by ossification prophylaxis (radiotherapy and Indomethacin). At follow-up of 12 months after revision surgery, elbow motion was unrestricted with a strength grade 5/5. The patient was free of pain and reported no restrictions in daily as well as sporting activities. Radiologic assessment showed no recurrence of heterotopic bone tissue. Conclusion Intraoperative radiographic and clinical examination of the elbow is highly recommended to identify incorrect hardware positioning and, therefore, to avoid serious postoperative complications in TBW.

Abstract
BACKGROUND Olecranon fractures represent 10% of upper extremity fractures. There is a growing body of literature to support the use of plate fixation for displaced olecranon fractures. The purpose of this survey was to gauge Canadian surgeons' practices and preferences for internal fixation methods for displaced olecranon fractures. METHODS Using an online survey tool, we administered a cross-sectional survey to examine current practice for fixation of displaced olecranon fractures. RESULTS We received 256 completed surveys for a response rate of 31% (95% confidence interval [CI] 30.5-37.5%). The preferred treatment was tension band wiring (78.5%, 95% CI 73-83%) for simple displaced olecranon fractures (Mayo IIA) and plating (81%, 95% CI 75.5-85%) for displaced comminuted olecranon fractures (Mayo IIB). Fracture morphology with a mean impact of 3.31 (95% CI 3.17-3.45) and comminution with a mean impact of 3.34 (95% CI 3.21-3.46) were the 2 factors influencing surgeons' choice of fixation method the most. The major deterrent to using tension band wiring for displaced comminuted fractures (Mayo IIB) was increased stability obtained with other methods described by 75% (95% CI 69-80%) of respondents. The major deterrent for using plating constructs for simple displaced fractures (Mayo IIA) was better outcomes with other methods. Hardware prominence was the most commonly perceived complication using either method of fixation: 77% (95% CI 71.4-81.7%) and 76.2% (95% CI 70.6-81.0%) for tension band wiring and plating, respectively. CONCLUSION Divergence exists with current literature and surgeon preference for fixation of displaced olecranon fractures.

Abstract
PURPOSE The complication rate of a tension band wiring (TBW) used for the internal fixation of olecranon fractures remains high. The aim of this study was to compare the stability of a novel olecranon tension plate (OTP) with TBW in a simulated fracture model. METHODS We tested 12 fresh frozen-pairs of cadaver proximal ulnae treated with OTP and TBW under cyclic loading. The elbow motion ranged from full extension to 90° of flexion, and the pulling force of the triceps tendon ranged from 50 to 350 N. The displacement of the fracture fragments was measured continuously. Data were assessed statistically using the Wilcoxon test with significance level of p < 0.05. RESULTS The cyclic loading tests showed median displacements of the fracture fragments of 0.25 mm using OTP and 1.12 mm for TBW. Statistical analysis showed the difference to be substantial (p = 0.086) but not statistically significant. No plate breakage or screw loosening occurred. CONCLUSIONS The concept of replacing prominent K-wires at the proximal end of the ulna using an low-profile plate with classical lag and multidirectional angle-stable screws demonstrated biomechanical advantages over TBW.

Abstract
The aim of this study was to report the epidemiological characteristics and the experience of 5 departments of trauma, in France, in the management of fractures of the proximal ulna. 163 patients with fractures of the proximal ulna with a mean age of 49.9 years (range 16-97) were managed. The most common mode of injury was a motor vehicle collision (48%). 18% sustained associated injuries to the ipsilateral limb. Open fractures were present in 42 patients (25%). A total of 109 patients had a fracture of the olecranon, with the Mayo 2A and B types most frequently seen (66%). The patients were invited for clinical examination at a mean duration of 16 months, retrospectively. Validated patient-oriented assessment scores involving the Mayo Elbow Performance Index (MEPI) and the Broberg and Morrey score were evaluated. All patients had follow-up radiographs. The mean arc of elbow motion was 130° (70-150°). The mean MEPI was 91 (20-100) with good results in 23% and excellent results in 52% of the patients. The mean Broberg and Morrey score was 90 after isolated olecranon fracture, and decreased with the complexity of the lesion. 117 fractures (72%) healed with ulnohumeral congruity. 9 fracture non-unions occurred (6%). Although the fracture of the proximal ulna can be described in several classifications, none of them accommodate it satisfactorily, because of the complexity of the lesion. The coronoid process is the keystone for the stability of the elbow. It forms the anterior buttress with the radial head. Tension band wire fixation is by far the commonest technique of internal fixation used for the treatment of non-comminuted olecranon fractures. Dorsal plate fixation is a useful option by providing improved fixation of complex comminuted fractures and fracture-dislocations. The radiocapitellar joint has to be restored appropriately, preserving the radial head when possible and replacing it with a prosthesis otherwise. The lateral collateral ligament complex is commonly disrupted and usually can be reattached to its origin from the lateral epicondyle. In addition, a brief period of hinged external fixation should be considered.

Abstract
PURPOSE Although tension band wiring (TBW) is generally accepted as standard treatment for olecranon fractures, it has several shortcomings such as loss of reduction, skin irritation, and migration of the K-wires. To overcome these problems and increase fixation stability, we used a rigid fixation technique with double tension band wiring (DTBW). Here, we describe the technique and outcomes of the treatment. METHODS We retrospectively reviewed 21patients with olecranon fractures who were treated by DTBW. We evaluated clinical and radiological outcomes by checking the range of motion, loss of reduction, functional scoring, skin complications, and pin migration. There were 15 cases of Mayo type IIA fractures (71%) and 6 of type IIB fractures (29%). The mean follow-up period was 37 months (range, 12-58 mo). We also compared the mechanical stability of DTBW and TBW in a sawbone model using a single cycle load to failure protocol. RESULTS All fractures united without displacement, and no migration of the K-wires was observed during the period of follow-up. Mean loss of elbow extension was 2° (range, 0°-15°) and mean elbow flexion was 134° (range, 125°-140°). The mean Mayo Elbow Performance Score was 94 (range, 70-100). Biomechanical testing revealed greater mechanical strength in the DTBW technique than in the TBW when measured by mean maximum failure load and mean bending moment at failure. CONCLUSIONS DTBW produced good clinical and radiological outcomes and could be an effective option for the treatment of olecranon fractures by providing additional stability through a second TBW. Biomechanical comparison with a control group (TBW) supported the mechanical benefits of DTBW. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Our aim was to determine the effectiveness of a new surgical technique for olecranon fractures using a tension plate (TP) designed by the operating surgeon. METHODS We included patients with olecranon fractures treated between September 2010 and August 2013 in our study. Treatment involved a new implant and operative technique, which combined the most favourable characteristics of 2 frequently used methods, tension band wiring and plate osteosynthesis, while eliminating their shortcomings. The new method was based on the newly constructed implant. RESULTS Twenty patients participated in our study. We obtained the following functional results with our TP: median flexion 147.5° (interquartile range [IQR] 130°- 155°), median extension 135°/deficit 10° (IQR 135°-145°), median pronation 90° (IQR 81.3°-90°), median supination 90° (IQR 80°-90°). Implant-related complications were noted in 1 patient, and implants were removed in 3 patients. The mean functional Mayo elbow performance score was 94.8 (range 65-100). The removal of the implant was considerably less frequent in patients operated using the new method and implant than in patients operated using conventional methods at our institution (p < 0.001). Mean duration of follow-up was 8 months. CONCLUSION Our TP for the treatment of olecranon fractures is safe and effective. Functional results are very good, with significantly decreased postoperative inconveniences and need to remove the implant. Less osteosynthetic material was used for TP construction, but stability was preserved.

Abstract
BACKGROUND Fractures of the olecranon (the bony tip of the elbow) account for approximately 1% of all upper extremity fractures. Surgical intervention is often required to restore elbow function. Two key methods of surgery are tension band wire fixation and plate fixation. OBJECTIVES To assess the effects (benefits and harms) of different surgical interventions in the treatment of olecranon fractures in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (22 September 2014), the Cochrane Central Register of Controlled Trials (CENTRAL, 2014, Issue 8), MEDLINE (1946 to September week 2 2014), EMBASE (1980 to 19 September 2014), trial registers, conference proceedings and reference lists of articles. SELECTION CRITERIA Randomised controlled trials (RCT) and quasi-RCTs that compared different surgical interventions for the treatment of olecranon fractures in adults. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, risk of bias assessment and data extraction. The primary outcomes of this review were function, pain and adverse events. MAIN RESULTS We included six small trials involving 244 adults with olecranon fractures. Of these, four were RCTs and two were quasi-RCTs; both of were at high risk of selection bias. All six trials were at high risk of performance bias, reflecting lack of blinding, and four trials were at high risk of detection bias. The quality of the evidence for most outcomes was generally very low because of limitations in study design and implementation, and either imprecision of the results or inadequate outcome measures. Thus, we are very uncertain about the estimates of effect.One trial (41 participants) comparing plate fixation with standard tension band wiring provided very low quality evidence at 16 to 86 weeks' follow-up of a better clinical outcome after plate fixation (good outcome (little pain or loss of elbow motion): 19/22 versus 9/19, risk ratio (RR) 1.82 favouring plate fixation, 95% confidence interval (CI) 1.10 to 3.01). There was very low quality evidence of less symptomatic prominent metalwork after plate fixation (1/22 versus 8/19; RR 0.11, 95% CI 0.01 to 0.79). The results for other adverse effects (infection and delayed or non-union) were inconclusive. Evidence is pending from a newly (September 2014) completed trial (67 participants) making the same comparison.Four trials compared four different modified techniques of tension band wiring (i.e. additional intramedullary screw fixation, biodegradable pins, Netz pins and cable pin system) versus standard tension band wiring. There was very low quality evidence of little difference at six to 14 months in function assessed by a non-validated scoring tool from the addition of an intramedullary screw. However, there were fewer cases of metalwork prominence in the intramedullary screw group (1/15 versus 8/15; RR 2.00, 95% CI 1.15 to 3.49; one trial; 30 participants). There was very low quality evidence from one trial (25 participants) of little difference in subjectively or objectively assessed good outcome at a mean of 20 months between tension band wiring with biodegradable implants versus metal implants. There were no adverse events, either non-union or sinus or fluid accumulation, reported. All 10 participants in the metalwork group had an extra operation to remove their metalwork at one year. One trial, which did not report on function or pain, provided very low quality evidence of lower rates of metalwork for any reason or for symptoms after Netz pin tension band wiring compared with standard tension band wiring (11/21 with Netz pin versus 17/25 with standard tension band wiring; RR 0.77, 95% CI 0.47 to 1.26; 46 participants); this evidence also supports the possibility of higher rates of metalwork removal for Netz pins. Two intra-operative complications occurred in the Netz pin group. The fourth trial, which compared the cable pin system with standard procedure, found low quality evidence that cable pin improved functional outcome at a mean of 21 months (Mayo Elbow Performance Score (MEPS), range 0 to 100: best outcome: mean difference (MD) 7.89 favouring cable pin, 95% CI 3.14 to 12.64; one trial; 62 participants). It also found low quality evidence of fewer postoperative complications in the cable pin group (1/30 with cable pin system versus 7/32 standard tension band wiring; RR 0.15, 95% CI 0.02 to 1.17), although the evidence did not rule out the converse.One trial provided very low quality evidence of similar patient-reported function using the Disabilities of the Arm, Shoulder and Hand questionnaire (0 to 100: worst function) at two or more years after fixation using a novel olecranon memory connector (OMC) compared with locking plate fixation (MD -0.70 favouring OMC, 95% CI -4.20 to 2.80; 40 participants). The only adverse event was a superficial infection in the locking plate group. AUTHORS' CONCLUSIONS There is insufficient evidence to draw robust conclusions on the relative effects of the surgical interventions evaluated by the included trials. Further evidence, including patient-reported data, on the relative effects of plate versus tension band wiring is already pending from one recently completed RCT. Further RCTs, using good quality methods and reporting validated patient-reported measures of function, pain and activities of daily living at set follow-ups, are needed, including checking positive findings such as those relating to the use of an intramedullary screw and the cable pin system. Such trials should also include the systematic assessment of complications, further treatment including routine removal of metalwork and use of resources.

Abstract
BACKGROUND Tension-band wiring is a popular method of internal fixation for simple olecranon fractures. Although fracture union rates and clinical outcomes are good, up to 80% of patients require removal because of prominent/symptomatic metalwork. The current literature remains unclear as to the best orientation of the longitudinal wires to minimize hardware failure. The aim of this study was to determine the surgically modifiable factors related to spontaneous wire pullout. METHODS A retrospective review of hospital theater records over a period of 6 years was performed to identify all olecranon tension-band wire procedures. Preoperative radiographs were used to confirm and classify the fracture. Intraoperative and postoperative radiographs were analyzed for a number of wire-associated variables: wire length within the ulna, medullary/cortical position, parallelism of wires, proximal wire prominence, wire angle relative to the ulna, distance from the articular surface, fracture gap, and subsequent pullout. RESULTS A total of 182 wires were analyzed. The mean age was 52.5 years, and the mean radiographic follow-up period was 7.3 months. Intramedullary wires had a mean pullout of 5.5 mm compared with 2.4 mm for transcortical wires (P < .0001). A multiple regression model noted 7 independent variables affecting wire pullout: age, bent wires, medullary/transcortical wire positioning, proximal prominence, ulnar shaft angle, distance from the articular surface, and articular step. CONCLUSION To minimize postoperative pullout of wires, we suggest anatomic reduction and transcortical wire orientation, without bending, in the subchondral bone close to the articular surface.

Abstract
PURPOSE The tension band wiring (TBW) technique is a common treatment for the fixation of olecranon fractures with up to three fragments. The literature and surgeons describe TBW as an uncomplicated, always available and convenient operation producing excellent results. The purpose of this study was to determine whether TBW is more ambitious than believed or the procedure provides an increased level of tolerance concerning the surgical technique. METHODS This study reviewed 239 TBW cases in patients with olecranon fractures or osteotomies. We reviewed a total of 2,252 X-rays for ten operative imperfections: (1) nonparallel K-wires, (2) long K-wires, (3) K-wires extending radially outwards, (4) insufficient fixation of the proximal ends of the K-wires, (5) intramedullary K-wires, (6) perforation of the joint surface, (7) single wire knot, (8) jutting wire knot(s), (9) loose figure-of-eight configuration, and (10) incorrect repositioning. RESULTS On average, there were 4.24 imperfections per intervention in the cases reviewed. A total of 1,014 of 2,390 possible imperfections were detected. The most frequent imperfections were insufficient fixation of the proximal ends of the K-wires (91% of all cases), the use of a single wire knot (78%) and nonparallel K-wires (72%). Mayo IIa (n = 188) was the most common fracture type. CONCLUSIONS Our results and the number of complications described by the literature together support the conclusion that TBW is not as easy as surgeons and the literature suggest. Although bone healing and the functional results of TBW are excellent in most cases, the challenges associated with this operation are underestimated. LEVEL OF EVIDENCE IV, treatment study.

Abstract
PURPOSE To evaluate the clinical and radiographic outcomes of tension band wiring of displaced olecranon fractures treated using Kirschner wires with eyelets to assess their clinical performance with respect to complications such as backing out of the K-wires, restriction of forearm rotation, and neurovascular injury. METHODS The authors retrospectively reviewed 44 patients treated for an isolated, displaced olecranon fracture and checked range of motion, postoperative pain, complications, and incidence of hardware removal. The mean follow-up period was 41 months (range, 26-73 mo). RESULTS All fractures united, and anatomical reduction was achieved in all cases at final follow-up. Mean elbow flexion was 135° (range, 115° to 140°), and mean elbow extension was 4° (range, 0° to 15°). No pin migration, restriction of forearm rotation, or neurovascular injury occurred. Hardware removal was performed in 8 cases (18%). Compared to previous results with conventional Kirschner wires, no meaningful improvement in postoperative pain level or in the rate of hardware removal was observed. CONCLUSIONS Tension band wiring using the pin studied produced excellent clinical and radiologic outcomes for the treatment of isolated, displaced Mayo type IIA and some type IIB olecranon fractures. The pin was effective in preventing the backing out of Kirschner wires and avoiding the complications associated with anterior cortical engagement of Kirschner wires, such as neurovascular injury or restriction of forearm rotation.

Abstract
Olecranon fractures are intra-articular injuries that require anatomic restoration of the articular surface. For most simple noncomminuted transverse olecranon fractures, tension band wire fixation can provide a stable construct to allow for early joint range of motion. However, in comminuted olecranon fractures, it is difficult to provide a sufficient buttress for impacted articular fragments using tension band wire fixation. Therefore, plate fixation is the standard fixation method, but wide skin exposure and symptomatic plate irritation on the skin are common complications. The authors' technique uses tension band wire fixation with miniplate augmentation for patients with comminuted olecranon fractures.

Abstract
INTRODUCTION Several methods of transverse patellar and olecranon fixation have been described. This article compares biomechanical studies of various fixation methods using a newly developed scoring method. SOURCE OF DATA The databases PubMed, Web of Science, Science Direct, Google Scholar and Google were searched for relevant studies. AREAS OF AGREEMENT Fixation hardware failure remains a problem. Various materials and fixation techniques have been tested to provide an improved fixation of transverse olecranon and patellar fractures. AREAS OF CONTROVERSY The difference in biomechanical testing setup between the studies makes it hard to compare different fixation techniques. GROWING POINTS The newly developed grading method was proved to be unbiased and reliable; however, extra specifications need to be added at some criteria when adopting the scoring method. AREAS TIMELY FOR DEVELOPING RESEARCH Non-metallic constructs may provide an improvement to the currently used metallic tension band wiring technique; however, clinical research is required.

Abstract
OBJECTIVE: This prospective, randomized study compared the effectiveness of the cable pin system (CPS) versus tension band wiring (TBW) for olecranon fracture fixation. METHODS: Patients with acute transverse or slight oblique olecranon fractures were randomly divided into two groups: one fixed by CPS and the other by TBW. Clinical outcome data were collected and analysed following a mean duration of 21 months. RESULTS: The mean ± SD fracture healing time was significantly shorter in the CPS group ( n = 30; 9.73 ± 2.02 weeks) compared with the TBW group ( n = 32; 11.13 ± 2.21 weeks). One patient in the CPS group and seven patients in the TBW group experienced postoperative complications; this difference was statistically significant. The mean ± SD Mayo Elbow Performance Score in the CPS group was significantly higher (88.67 ± 6.42) than that in the TBW group (80.78 ± 11.99). Logistic regression analysis showed an association between fixation method and fracture healing time, complications and elbow function. CONCLUSIONS: Internal fixation by CPS is an effective method for olecranon fracture and is associated with a shorter healing time, fewer complications and better function than TBW.

Abstract
BACKGROUND Tension-band wiring (TBW) has been accepted as the treatment of choice for displaced olecranon fractures. The aim of this study was to examine the effect of K-wire position on instability of the K-wires in relation to local complications and radiological and clinical long-term outcome. METHODS We reviewed the early follow-up of 59 patients (mean age, 60 years) who underwent TBW osteosynthesis for displaced olecranon fractures. Follow-up information was available from medical records and radiographs. The main outcome measurements were proximal migration of the wires, gap, step, range of motion, and complications. Long-term follow-up included 21 patients (mean age, 58 years). Follow-up was available from a clinical visit and a radiograph. Visual Analogue Scale (VAS), Mayo Elbow Performance Score (MEPS), Disabilities of the Arm Shoulder and Hand (DASH), EuroQol-5D (EQ-5D), and Broberg and Morrey osteoarthritis scores were obtained. RESULTS Seventy-eight percent of the patients treated with intramedullary K-wires were found to have instability of K-wires, compared to 36% in the patients treated with transcortical K-wires. Patients with instability of the K-wires tend to develop osteoarthritis more often. There is a better functional outcome in patients where the osteosynthetic material is removed. CONCLUSION Instability of K-wires after TBW is more common after intramedullary placement of the wires resulting in proximal migration of the K-wires and gap appearance. There was a tendency of more osteoarthritis in the group of patients where instability of K-wires was identified. We would recommend the use of transcortical placed wires, as well as to have a low threshold in removing the implants.

Abstract
PURPOSE Displaced olecranon fractures are often amenable to treatment with open reduction and tension-band wiring. The purpose of this study is to examine the relationships of the tips of K-wires used in a tension-band construct to volar neurovascular structures in the proximal forearm and the proximal radioulnar joint. METHODS We performed simulated percutaneous pinnings of the proximal ulna under fluoroscopic guidance on 15 cadavers with intact proximal ulnas. The K-wires were drilled obliquely through the tip of the olecranon process and directed to engage the anterior ulnar cortex, distal to the coronoid. Using calipers, we measured the distance from the tip of each pin to the anterior interosseous nerve (AIN), ulnar artery, proximal radioulnar joint (PRUJ), and volar cortex of the ulna, as well as the distance from the volar cortex of the ulna to the AIN and ulnar artery. The angle created by the K-wires and the longitudinal axis of the ulna was measured on both anteroposterior and lateral radiographs. RESULTS The distance from pin tip to the AIN and ulnar artery measured a mean of 16 mm with a standard deviation of 6 mm and 14 mm with a standard deviation of 5 mm, respectively, with 1 pin abutting the artery. The shortest distance from both the AIN (11 ± 5 mm) and the ulnar artery (8 ± 6 mm) was measured with the shallowest angle of insertion, ranging from 10° to 14.9° on lateral radiographs. The mean distance between the pin tip and the PRUJ measured 7 mm with a standard deviation of 4 mm, with 3 pins penetrating the PRUJ. CONCLUSIONS The impaction of K-wires under the triceps is often approximately 1 cm, which is similar to the distance of the K-wire tips to the AIN and ulnar artery. Our findings suggest that larger insertion angles might help avoid neurovascular injury when the insertion point of the K-wires is at or just proximal to the tip of the olecranon. In this study, the safe zone for pin insertion on the anteroposterior view is 0° to 10°, and on the lateral view it is 20° to 30°. CLINICAL RELEVANCE This anatomic study was done to diminish the chance of complications resulting from K-wire placement during tension-band wiring for olecranon fractures.

Abstract
The treatment of olecranon fractures frequently involves the use of tension-band fixation. Although associated with high union rates, this method has a high incidence of morbidity associated with soft tissue compromise and limitation of range of movement requiring frequent re-operation for removal of metal. We describe the use of a simple jig to ensure intramedullary placement of longitudinal K-wires and compare the accuracy of placement of Kirschner (K)-wires using this device with the traditional free-hand method. We found the distance from the centre of the medullary canal, the range and standard deviations of K-wire positions to be significantly more precise when the jig was used. This has applications for the use of the device, both with standard metallic radio-opaque wires and potentially with bio-absorbable pins.

Abstract
INTRODUCTION The gold standard for treating transverse olecranon fractures is tension band fixation. A problem with this technique is migration of the K-wires leading to premature hardware removal. The aim of this study is to compare stability provided by two new techniques designed to eliminate the problem with backing out of K-wires, with that of the recommended tension band technique, performed with a biomechanical in vitro investigation. Our hypothesis was that the two new techniques would provide at least equal stability as the traditional tension band fixation. METHODS Transverse olecranon osteotomies were created in human cadaveric elbows to simulate a type 21-B1.1 fracture. Three groups of 8 specimens were instrumented with: (1) recommended AO tension band technique; (2) modified K-wires with eyelets and tension band; (3) staples across the fracture with tension band. Each elbow was tested in a 90° flexed position. The triceps tendon was sinusoidally loaded by applying two load steps at 500 and 700 N for 4000 cycles each. Relative movements between the fragments were determined. RESULTS At the end of the first and second load step the displacement of the osteotomy at the posterior ulnar side was significantly less for the staples across the fracture with tension band as compared to both other groups. There were no significant differences between groups 1 and 2. CONCLUSION Since clinical results depend partly on stable fixation, it is concluded that using staples in the clinical situation might provide better results than the currently recommended tension band technique.

Abstract
INTRODUCTION New concepts in plate fixation have led to an evolution in plate design for olecranon fractures. The purpose of this study was to compare the stiffness and strength of locking compression plate (LCP) fixation to one-third tubular plate fixation in a cadaveric comminuted olecranon fracture model with a standardised osteotomy. MATERIALS AND METHODS Five matched pairs of cadaveric elbows were randomly assigned for fixation by either a contoured LCP combined with an intramedullary screw and unicortical locking screws or a one-third tubular plate combined with bicortical screws. Construct stiffness was measured by subjecting the specimens to cyclic loading while measuring gapping at the osteotomy site. Construct strength was measured by subjecting specimens to ramp load until failure. RESULTS There was no significant difference in fixation stiffness and strength between the two fixation methods. All failures consisted of failure of the bone and not of the hardware. CONCLUSION Contoured LCP and intramedullary screw fixation can be used as an alternative treatment method for comminuted olecranon fractures as its stiffness and strength were not significantly different from a conventional plating technique.

Abstract
Various methods are used to treat comminuted fractures of the olecranon. The preferred method of management of fractures of the olecranon is tension band wiring over K-wires. Often, it becomes difficult to fix small articular fragments with the 2 K-wires used for tension band wiring. Since 2005, we have used the missing K-wire technique to fix the small articular fragments.

Abstract
Several options exist for the management olecranon fractures. These include tension band, plate and intramedullary fixation techniques as well as fragment excision with triceps advancement and non-operative management. No one technique is suitable for the management of all olecranon fractures. In deciding how to treat this common trauma presentation, the surgeon needs a good understanding of the anatomy, different fracture morphologies, surgical options and potential complications. With appropriate management and early mobilisation good functional results can be expected in the majority of patients.

Abstract
Placing K-wires obliquely through the anterior ulnar cortex is a common modification of traditional olecranon tension-band wiring. Wire tip protrusion, however, risks injury to adjacent neurovascular structures and may impede forearm rotation. This study examines the proximity of neurovascular structures to the anterior proximal ulnar cortex. The anatomy of 47 adult elbows was examined through magnetic resonance imaging. A radiologist measured the spatial relationship of 6 neurovascular structures to a mid-sagittal reference point 1.5 cm distal to the coronoid on the anterior surface of the ulna. Distance and angular measurements were made in the transverse plane of the reference point. Within a reasonable arc of K-wire placement, the ulnar artery and median nerve were at greatest risk yet were still beyond 10 mm from the anterior ulnar cortex. To avoid iatrogenic neurovascular injury during tension-band wiring of the olecranon, protrusion of wire tips beyond the anterior ulnar cortex should be no more than 1 cm at a distance of 1.5 cm distal to the coronoid.
