Arch Orthop Trauma Surg 2024:10.1007/s00402-024-05444-w. [PMID: 38967783 DOI: 10.1007/s00402-024-05444-w] [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: 06/07/2024] [Accepted: 06/27/2024] [Indexed: 07/06/2024]
Abstract
INTRODUCTION Treatment for complex olecranon fractures with metaphyseal comminution can be challenging. To improve reduction maneuvers and augment stability, we apply a small medial and/or lateral locking compression plate (LCP) prior to placing a posterior contoured 3.5 mm-2.7 mm LCP. The aim is to describe our technique and outcomes of this "orthogonal" plating technique. MATERIAL AND METHODS 26 patients were treated with orthogonal plating. Clinical outcome variables were available for all patients at a median of 27 months (IQR 6-54), and patient-reported outcomes (Q-DASH and MEPS) for 23 patients at 38 months (IQR 18-71). RESULTS All fractures healed at a median of 2.0 months (IQR 1.5-3.8). The median elbow flexion was 120°, extension-deficit 15°, pronation 88°, and supination 85°. The median Q-DASH was 9 (IQR 0-22) and the median MEPS was 90 (IQR 80-100). Hardware was electively removed in seven patients. One patient had a late superficial infection that resolved with hardware removal and antibiotics, and one patient had two consecutive re-fractures after two hardware removals; and healed after the second revision surgery. CONCLUSION Orthogonal plating with a posterior LCP and a small medial and/or lateral LCP is a safe technique that leads to excellent healing rates, and good clinical and patient-reported outcomes.

Arch Orthop Trauma Surg 2023; 143:6251-6259. [PMID: 37460845 PMCID: PMC10491518 DOI: 10.1007/s00402-023-04979-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 06/29/2023] [Indexed: 09/10/2023]
Abstract
INTRODUCTION Proximal ulna fractures with a large zone of comminution, such as in the context of Monteggia injuries, require mechanically strong osteosyntheses as they occur in regions with high physiological joint load. Consequently, implant failure and pseudarthrosis are critical and devastating complications, especially with the background of mainly young patients being affected. An effective solution could be provided by adding a small second plate 90° angulated to the standard dorsal plate in the area of non-union. Thus, this study investigates whether, from a biomechanical point of view, the use of such a mini or baby plate is worthwhile. MATERIALS AND METHODS Comminuted fractures distal to the coronoid process, equivalent to Jupiter type IIb fractures, are generated on artificial Sawbones® of the ulna and stabilized using two different plate osteosyntheses: in the first group, a dorsal locking compression olecranon plate is used (LCP group). In the second group, a small, ulnar 5-hole olecranon plate is added as a baby plate in addition to the mother plate at the level of the fracture zone (MBP group). Dynamic biomechanical loading in degrees of flexion from 0° to 90° is carried out to determine yield load, stiffness, displacement, and changes in fracture gap width as well as bending of the dorsal plate. RESULTS The "mother-baby-plate" osteosynthesis had a significantly higher yield load (p < 0.01) and stiffness (p = 0.01) than the LCP group. This correlates with the increased movement of the proximal fracture element during cyclic testing for the LCP group compared to the MBP group as measured by an optical metrology system. CONCLUSIONS Here, we show evidence that the addition of a small plate to the standard plate is highly effective in increasing the biomechanical stability in severe fractures equivalent to Jupiter type IIb. As it hopefully minimizes complications like pseudarthrosis and implant failure and as the additional preparatory effort leading to compromised blood supply is regarded to be negligible, this justifies and highly advises the use of a mother-baby-plate system.

The Effectiveness of Three-Dimensional Osteosynthesis Plates versus Conventional Plates for the Treatment of Skeletal Fractures: A Systematic Review and Meta-Analysis. J Clin Med 2023; 12:4661. [PMID: 37510776 PMCID: PMC10380957 DOI: 10.3390/jcm12144661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 06/07/2023] [Accepted: 06/25/2023] [Indexed: 07/30/2023] Open
Abstract
PURPOSE To assess the difference between preformed anatomically shaped osteosynthesis plates and patient-specific implants versus conventional flat plates for the treatment of skeletal fractures in terms of anatomical reduction, operation time, approach, patient outcomes, and complications. MATERIAL AND METHODS MEDLINE (1950 to February 2023), EMBASE (1966 to February 2023), and the Cochrane Central Register of Controlled Trials (inception to February 2023) databases were searched. Eligible studies were randomised clinical trials, prospective controlled clinical trials, and prospective and retrospective cohort studies (n ≥ 10). Inclusion criteria were studies reporting the outcomes of preformed anatomically shaped osteosynthesis plates and patient-specific implants versus conventional flat plates after treating skeletal fractures. Outcome measures included anatomical reduction, stability, operation time, hospitalisation days, patients' outcomes, and complications. Two independent reviewers assessed the abstracts and analysed the complete texts and methodologies of the included studies. RESULTS In total, 21 out of the 5181 primarily selected articles matched the inclusion criteria. A meta-analysis revealed a significant difference in operation time in favour of the preformed anatomical plates and patient-specific implants versus conventional plates. Significant differences in operation time were found for the orbital (95% CI: -50.70-7.49, p = 0.008), upper limb (95% CI: -17.91-6.13, p < 0.0001), and lower limb extremity groups (95% CI: -20.40-15.11, p < 0.00001). The mean difference in the rate of anatomical reduction in the lower limb extremity group (95% CI: 1.04-7.62, p = 0.04) was also in favour of using preformed anatomical plates and patient-specific implants versus conventional plates. CONCLUSIONS This systematic review showed a significant mean difference in surgery time favouring the use of preformed anatomical plates and patient-specific implants for orbital, upper, and lower limb extremity fractures. Additionally, preformed anatomical plates and patient-specific implants in the lower limb group result in a significantly higher rate of anatomical reduction versus conventional flat plates.

Elimination of irreducible intercalary fragment and fixation using locking plate for Mayo type IIB olecranon fracture-outcomes compared with type IIA. Arch Orthop Trauma Surg 2022; 142:3229-3237. [PMID: 34414491 DOI: 10.1007/s00402-021-04127-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 08/12/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND We hypothesized that the outcomes of articular reduction with elimination of irreducible articular intercalary fragments for Mayo type IIB fractures fixed using olecranon locking plates would be as satisfactory as those of noncomminuted fractures. METHODS A total of 65 patients were enrolled from among 92 who had undergone operative treatment for olecranon fractures between March 2008 and February 2015. Patients with fragments that were eliminated because they were too comminuted to be fixed during surgery (type IIB) were included in group 1. Patients without intraarticular comminuted fragments (type IIA) or with very few fragments were assigned to group 2. In group 1, articular congruency and reduction status were confirmed by direct visualization. The fracture was then fixed with a locking plate and irreducible intercalary fragments were eliminated. RESULTS There were no significant differences in demographic characteristics, such as age and gender, between the two groups. Both groups achieved bony union within the approximately 6-year follow-up period and there were no serious complications in either group. The grades of heterotrophic ossification and ulnohumeral arthritis were not significantly different between the groups. The mean flexion-extension and pronation-supination arcs were similarly satisfactory in both groups (127.35° and 134.39° vs. 129.69° and 133.75° in groups 1 and 2°, respectively). Clinical outcomes including visual analog scale pain scores, as well as the Mayo Elbow Performance scores (87.73 vs. 88.28 in groups 1 and 2, respectively), were also similarly satisfactory in both groups. CONCLUSIONS Locking plate fixation under direct visualization (to reduce the articular surface in Mayo type IIB fractures) and elimination of articular intercalary fragments resulted in satisfactory radiologic and clinical outcomes, similar to those of noncomminuted fractures also treated using a locking plate.

Abstract
OBJECTIVE The application of double plating in olecranon fractures is becoming increasingly widespread. There is no research comparing this technique with traditional tension band wiring (TBW) and the single plate technique. The purpose of this study was to compare the efficacy of three fixation techniques in olecranon fractures. MATERIALS AND METHODS From March 2016 to May 2020, we collected the clinical data of 95 patients with olecranon fractures who underwent surgical treatment. Thirty-five patients received TBW surgery (TBW Group), 32 patients received a 3.5 mm locking compression plate (LCP, 3.5 mm LCP Group), and 28 patients received double mini-locking plate treatment (DP Group). The operation time, fracture union time, time of return to work, range of motion (ROM), soft tissue stimulation to remove internal fixation, and patient-related functional results (the Weseley score, Mayo Elbow Performance Score [MEPS], and Disabilities of Arm, Shoulder and Hand Score [DASH]) were recorded. The clinical results and complications of the three internal fixation techniques were compared. RESULTS The average follow-up time was 15.011.82 months (12-18 months). All patients' fractures healed by first intention. There were no statistically significant differences in the operation time, fracture union time, ROM, Weseley score, MEPS or DASH scores of the three groups of patients. The postoperative return time for patients in the TBW group was 10.002.15 weeks, the 3.5 mm LCP group was 9.561.93 weeks, and the DP group was 8.432.38 weeks (P = 0.014); 12 patients in the TBW group required removal of plant due to soft tissue stimulation, the 3.5 mm LCP group had 8 cases, and the DP group had 2 cases (P = 0.038). CONCLUSION The postoperative clinical results and elbow joint function of patients with olecranon fractures fixed by tension band wiring, 3.5 mm LCP and double mini-locking plate are similar, which indicates that double-plate technology can be used as an alternative to the two groups of traditional techniques. In addition, double-plate technology also helps patients return to work earlier and has a lower incidence of soft tissue stimulation.

Abstract
PURPOSE Olecranon fractures, especially with a small proximal fragment, remain a surgical challenge. Soft tissue irritation and affection of the triceps muscle bear a risk of complications. In order to find an area for a soft-tissue sparing placement of implants in the treatment of olecranon fractures, we aimed to define and measure the segments of the proximal olecranon and evaluate them regarding possible plate placement. METHODS We investigated 82 elbow joints. Ethical approval was obtained from the local ethics committee, After positioning in an arm holder and a posterior approach we described the morphology of the triceps footprint, evaluated and measured the surface area of the triceps and posterior capsule and correlated the results to easily measurable anatomical landmarks. RESULTS We found a bipartite insertional footprint with a superficial tendinous triceps insertion of 218.2 mm2 (± 41.2, range 124.7-343.2), a capsular insertion of 159.3 mm2 (± 30.2, range 99.0-232.1) and a deep, muscular triceps insertion area of 138.1 mm2 (± 30.2, range 79.9-227.5). Olecranon height was 26.7 mm (± 2.3, range 20.5-32.2), and olecranon width was 25.3 mm (± 2.4, range 20.9-30.4). Average correlation between the size of the deep insertion and ulnar (r = 0.314) and radial length (r = 0.298) was obtained. CONCLUSIONS We demonstrated the bipartite morphology of the distal triceps footprint and that the deep muscular triceps insertion area by its measured size could be a possible site for the placement of fracture fixations devices. The size correlates with ulnar and radial length.

Abstract
BACKGROUND Although preventing triceps fragment displacement is essential for treating an olecranon fracture, we frequently encounter situations in which only a few screws can be fixed to the triceps fragment. The aim of this study was to compare the stability of double-plate fixation and posterior plate fixation for olecranon fractures when the triceps fragment was small and only 2 screws could be inserted. METHODS A composite ulna model was used to simulate olecranon fracture. Four groups were formed consisting of double-plate and posterior plates with cortical and locking screws. The cyclic loading test was conducted for 500 cyclic loads of 5 to 50 N on a specimen to measure micromotion and displacement of the gap caused by light exercise. The load-to-failure test was performed by applying a load until fixation loss, defined as when the fracture gap increased by 2 mm or more or catastrophic failure occurred, to measure the maximum load. RESULTS Eight samples per group were tested through the pilot study. All groups were stable with a micromotion of <0.5 mm. However, the mean micromotion showed significant differences between the 4 groups (P < .001, Table 1). In the mean micromotion during exercise, posterior plating with cortical screws was the most stable (0.09 ± 0.02 mm) while double-plating with cortical screws was the most unstable (0.42 ± 0.11 mm). At the maximum load, posterior plating with locking screws was the strongest (205.3 ± 2.8 N) while double-plating with cortical screws was the weakest (143.3 ± 27.1 N). There was no significant difference in displacement after light exercise between the groups. CONCLUSIONS This study showed that when 2 triceps screws were used, both groups were stable during light exercise, but posterior-plating was stronger than double-plating.

Double plating is associated with higher fixation strength than single plating in osteoporotic fractures of the scapular spine: a biomechanical study. Arch Orthop Trauma Surg 2022; 142:1859-1864.

Abstract
INTRODUCTION The number of atraumatic stress fractures of the scapular spine associated with reverse shoulder arthroplasty is increasing. At present, there is no consensus regarding the optimal treatment strategy. Due to the already weakened bone, fractures of the scapular spine require a high fixation stability. Higher fixation strength may be achieved by double plating. The aim of this study was to evaluate the biomechanical principles of double plating in comparison to single plating for scapular spine fractures. METHODS In this study, eight pairs (n = 16) of human shoulders were randomised pairwise into two groups. After an osteotomy at the level of the spinoglenoid notch, one side of each pair received fracture fixation with a single 3.5 LCP (Locking Compression Plate) plate. The contralateral scapular spine was fixed with a 3.5 LCP and an additional 2.7 LCP plate in 90-90 configuration. The biomechanical test protocol consisted of 700 cycles of dynamic loading and a load-to-failure test with a servohydraulic testing machine. Failure was defined as macroscopic catastrophic failure (screw cut-out, plate breakage). The focus was set on the results of specimens with osteoporotic bone quality. RESULTS In specimens with an osteoporotic bone mineral density (BMD; n = 12), the mean failure load was significantly higher for the double plate group compared to single plating (471 N vs. 328 N; p = 0.029). Analysis of all specimens (n = 16) including four specimens without osteoporotic BMD revealed no significant differences regarding stiffness and failure load (p > 0.05). CONCLUSION Double plating may provide higher fixation strength in osteoporotic bone in comparison to a single plate alone. This finding is of particular relevance for fixation of scapular spine fractures following reverse shoulder arthroplasty. LEVEL OF EVIDENCE Controlled laboratory study.

Abstract
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.

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.

A retrospective multicenter study. J Shoulder Elbow Surg 2020; 29:1275-1281. [PMID: 32284307 DOI: 10.1016/j.jse.2020.01.091] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 01/14/2020] [Accepted: 01/21/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND Because of poor soft-tissue coverage at the proximal ulna and prominent posteriorly positioned implants, hardware removal remains the most common reason for revision surgery of olecranon fractures that were operatively treated using plate osteosynthesis. We hypothesized that low-profile double-plate osteosynthesis would reduce the number of soft tissue-related hardware removals compared with single posterior plating whereas the functional results would be comparable. METHODS This study retrospectively included patients who were treated with low-profile double-plate osteosynthesis or a posterior 2.7-/3.5-mm locking compression plate (LCP) for isolated olecranon fractures from 3 study centers. In addition to the implant removal rate, functional outcome measures (range of motion; Mayo Elbow Performance Score; Disabilities of the Arm, Shoulder and Hand score) were statistically compared. RESULTS The study included 79 patients, with a mean follow-up period of 36 months (range, 24-77 months). Of these patients, 37 were treated with low-profile double-plate osteosynthesis and 42, with a 2.7-/3.5-mm LCP. The mean age was 57 years (range, 18-93 years). Range of motion after treatment with low-profile double-plate osteosynthesis and a 2.7-/3.5-mm LCP measured 129° (range, 80°-155°) and 139° (range, 100°-155°), respectively. The Mayo Elbow Performance Scores were 95 (range, 65-100) and 99 (range, 85-100), respectively (P = .028), and the Disabilities of the Arm, Shoulder and Hand scores were 5.0 (range, 0-49) and 4.6 (range, 0-28), respectively (P = .673). Hardware was removed in 32% and 50% of patients after treatment with double-plate osteosynthesis and a 2.7-/3.5-mm LCP, respectively (P = .11). Hardware removal owing to soft-tissue irritation was noted in 27% of patients after double-plate osteosynthesis and 38% after LCP treatment (P = .30). DISCUSSION Low-profile double-plate osteosynthesis for treating olecranon fractures resulted in good clinical outcomes. However, the rate of hardware removal was not significantly reduced, and the functional results were comparable to those of common single-posterior plate osteosynthesis.
