Aims. Olecranon fractures are usually caused by falling directly on to the olecranon or following a fall on to an outstretched arm. Displaced fractures of the olecranon with a stable ulnohumeral joint are commonly managed by open reduction and internal fixation. The current predominant method of management of simple displaced fractures with ulnohumeral stability (Mayo grade IIA) in the UK and internationally is a low-cost technique using tension band wiring. Suture or suture anchor techniques have been described with the aim of reducing the hardware related complications and reoperation. An all-suture technique has been developed to fix the fracture using strong synthetic sutures alone. The aim of this trial is to investigate the clinical and cost-effectiveness of tension suture repair versus traditional tension band wiring for the surgical fixation of Mayo grade IIA fractures of the olecranon. Methods. SOFFT is a multicentre, pragmatic, two-arm parallel-group, non-inferiority, randomized controlled trial. Participants will be assigned 1:1 to receive either tension suture fixation or tension band wiring. 280 adult participants will be recruited. The primary outcome will be the Disabilities of the Arm, Shoulder and Hand (DASH) score at four months post-randomization. Secondary outcome measures include DASH (at 12, 18, and 24 months), pain, Net Promotor Score (patient satisfaction), EuroQol five-dimension five-level score (EQ-5D-5L), radiological union, complications, elbow range of motion, and re-operations related to the injury or to remove metalwork. An economic evaluation will assess the cost-effectiveness of treatments. Discussion. There is currently no high-quality evidence comparing the clinical and cost effectiveness of the tension suture repair to the traditional tension band wiring currently offered for the internal fixation of displaced fractures of the olecranon. The Simple Olecranon Fracture Fixation Trial (SOFFT) is a randomized controlled trial with sufficient power and design rigour to provide this evidence for the subtype of Mayo grade IIA fractures.

Abstract. Introduction. Displaced olecranon fractures in the elderly are challenging due to associated comorbidities, poor tissue quality, high risk of complications, and the possible need for implant removal. Treatment options with such fractures range from non-operative management to internal fixation with various types of implants. Currently, there is no consensus on the treatment of olecranon fractures in the elderly with relatively low functional demand. Aim. The aim of this systematic review was to analyse the clinical outcomes of various treatment modalities for olecranon fracture in the elderly. Methods. We systematically reviewed the literature covering the treatment of olecranon fractures in the elderly according to PRISMA guidelines. We used search tools of Medline, Embase, Wiley online library, Cochrane and Scopus. Keywords used in the search were Olecranon fracture and Elderly OR Geriatric in all fields. Studies involving patients older than 60 years of age and all modalities of treatment were included. Results. 14 papers studying 270 patients were identified of which, 112 were treated non-operatively, 25 with limited fixation, 98 with tension band wire fixation, 34 with plate fixation, and 1 patient was treated with excision. Conclusions. Nonoperative as well as limited fixation were shown to provide satisfactory results in the elderly. Treatment decisions in this age group should be individualised to factors such as fracture stability, quality of bone & soft tissues, and patient's functional demand. We recommend a treatment protocol for treating olecranon fracture in the elderly based on the above factors

Introduction. In oblique olecranon fracture, fracture line begins in the trochlear notch and proceeds distally to the dorsal cortex of the ulna. We have experienced a nonunion of reverse oblique fracture. Hypothesis. Reverse oblique olecranon fracture has instability. Materials & Methods. 130 patients with an olecranon fracture were retrospectively evaluated. Inclusion criteria are that fracture line begins at the base of the coronoid process, distal portion of the trochlear notch, and proceeds proximally to the dorsal cortex of the ulna on the lateral radiograph. Fractures with articular comminution were excluded. Results. Seven patients met the criteria. They were associated with local injuries: anterior translation of the proximal radius and ulna, fracture of the medial epicondyle or the lateral condyle of the humerus. One out of five patients treated with tension band wiring (TBW) was revised with screw fixation because of nonunion. Discussion. The associated injuries suggested the anterior and valgus instability. A nonunion case suggests a requirement of more secure fixation. However, these findings are common in distal olecranon fracture. Therefore, the instability in our series is due to the distal location of fracture on the trochlear notch rather than reverse obliquity. The reverse obliquity attributes to small proximal fragment. Conclusion. Reverse oblique olecranon fracture has instability because of its distal location. It should be distinguished from simple, stable fracture

Introduction: Tension band wiring is a common technique for olecranon fracture fixation. The most commonly used material for the tension band is stainless steel wire. There are however problems associated with stainless steel wire. Ethibond (Ethicon Ltd, Edinburgh) has previously been cited as a suitable alternative material but not FiberWire. The biomechanical properties of FiberWire (Arthrex Ltd, Sheffield) as a tension band material have not been evaluated. This study aimed to investigate the properties of FiberWire and compare them with stainless steel wire and Ethibond. Methods: Saw-bone olecranons were osteotomised identically to create an olecranon fracture. Identical tension band constructs were produced using stainless steel wire, Ethibond and FiberWire. The construct was tested by cyclical loading with an ESH dynamic testing machine (Brierley Hill, West Mids). A preload of 5N was applied before cyclical loading at levels up to 200N. The fracture gap was measured with a displacement transducer (Tokyo Sokki Kenkyujo Co, Japan). Results: At loading up to 100N, the stainless steel wire allowed an average fracture gap of 200 micrometers. 5 gauge Ethibond allowed a larger fracture gap of 350 micrometers (p< 0.05). 2 gauge Fiberwire did not allow a significantly different fracture gap to Ethibond. Discussion: The fracture gap with suture material was greater than with stainless steel wire, but still less then 0.5mm with loading of 100N. Free body diagram calculations determine that in a 70 kg man, this would correspond to the forces expected in extending the elbow against gravity. This means that these alternative materials are mechanically suitable for use in clinical practice for tension bands. This can avoid some of the complications of stainless steel wire. Conclusion: 5 gauge Ethibond and 2 gauge FiberWire are biomechanically suitable as alternatives to stainless steel wire in tension band wire fixation of olecranon fractures

Aims. The aim of this study is to report the results of a case series of olecranon fractures and olecranon osteotomies treated with two bicortical screws. Methods. Data was collected retrospectively for all olecranon fractures and osteotomies fixed with two bicortical screws between January 2008 and December 2019 at our institution. The following outcome measures were assessed; re-operation, complications, radiological loss of reduction, and elbow range of flexion-extension. Results. Bicortical screw fixation was used to treat 17 olecranon fractures and ten osteotomies. The mean age of patients being treated for olecranon fracture and osteotomy were 48.6 years and 52.7 years respectively. Overall, 18% of olecranon fractures were classified as Mayo type I, 71% type II, and 12% type III. No cases of fracture or osteotomy required operative re-intervention. There were two cases of loss of fracture reduction which occurred in female patients ≥ 75 years of age with osteoporotic bone. In both cases, active extension and a functional range of movement was maintained and so the loss of reduction was managed non-operatively. For the fracture fixation cohort, at final follow-up mean elbow extension and flexion were -5. °. ± 5. °. and 136. °. ± 7. °. , with a mean arc of motion of 131. °. ± 11. °. . Conclusion. This series has shown that patients regain near full range of elbow flexion-extension and complication rates are low following bicortical screw fixation of olecranon fractures and osteotomy.

Aims. Compression and absolute stability are important in intra-articular fractures such as transverse olecranon fractures. This biomechanical study aims to compare tension band wiring (TBW) with plate fixation by measuring compression within the fracture. Methods. A cross-over design and synthetic ulna models were used to reduce variation between samples. Identical transverse fractures were created using a 0.5mm saw blade and cutting jig. A Tekscan(tm) force transducer was calibrated and placed within the fracture gap. Twenty TBW or Acumed(tm) plate fixations were performed according to the recommended technique. Compression was measured while the constructs were static and during simulated elbow range of movement exercises. Dynamic testing was performed using a custom jig reproducing cyclical triceps contraction of 20N and reciprocal brachialis contraction of 10N. Both fixation methods were tested on each sample. Half were randomly allocated to TBW first and half to plating first. Data was recorded using F-scan (v 5.72) and analysed using SPSS(tm) (v 16). Paired T-tests compared overall compression and compression at the articular side of the fracture. Results. The mean overall compression for plating was 819N (+/− 602N 95%CI), TBW overall compression: 77N (+/−19N 95%CI) (P=0.039). Articular side compression for plating: 343N (+/− 276N 95%CI), TBW: 1N (+/− 2N 95%CI). (P=0.038). During simulated movements, overall compression reduced in both groups: TBW -14N (+/−7N) Plating -173N (+/−32N) and no increase in articular side compression was detected in the TBW group. Conclusion. Precontoured plates such as the Acumed(tm) olecranon system can provide significantly greater compression, compared to TBW in transverse olecranon fractures. This was significant for compression over the whole fracture surface and specifically at the articular side of the fracture. Also, in TBW, overall compression reduced and articular side compression remained negligible during simulated triceps contraction, challenging the tension band principle

Background. 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. Objectives. We describe the use of a simple jig to ensure intramedullary placement of longitudinal K-wires and compare the accuracy of placement of wires using this device with the traditional free hand method. Methods & Materials. 10 orthopaedic surgical trainees passed 2 longitudinal k wires into synthetic ulnae. This was done using the free hand method and then plastic jig. The ulnae were then sectioned to identify the position of the wires relative to the intramedullary canal. Results. Of the free hand wires, only 11 of 20 were found to be intramedullary versus 20 of 20 in the group passed using the jig. (p<0.001). The mean distance from the center of the ulnar canal was 6.5 mm in the freehand group (range 1-18mm, SD 6.1mm) and 1.6 mm in the O-Jig group (range 1-2mm, SD 0.5mm). The difference in the mean distance from the centre was 4.9mm which was significant (p< 0.001). Conclusions. We found the distance from the centre of the medullary canal, the range and standard deviations of wire positions to be significantly more precise when the jig was used

Olecranon fractures are common injuries representing roughly 5% of pediatric elbow fractures. The traditional surgical management is open reduction and internal fixation with a tension band technique where the pins are buried under the skin and tamped into the triceps. We have used a modification of this technique, where the pins have been left out of the skin to be removed in clinic. The purpose of the current study is to compare the outcomes of surgically treated olecranon fractures using a tension-band technique with buried k-wires (PINS IN) versus percutaneous k-wires (PINS OUT). We performed a retrospective chart review on all pediatric patients (18 years of age or less) with olecranon fractures that were surgically treated at a pediatric academic center between 2015 to present. Fractures were identified using ICD-10 codes and manually identified for those with an isolated olecranon fracture. Patients were excluded if they had polytrauma, metabolic bone disease, were treated non-op or if a non-tension band technique was used (ex: plate/screws). Patients were then divided into 2 groups, olecranon fractures using a tension-band technique with buried k-wires (PINS IN) and with percutaneous k-wires (PINS OUT). In the PINS OUT group, the k-wires were removed in clinic at the surgeon's discretion once adequate fracture healing was identified. The 2 groups were then compared for demographics, time to mobilization, fracture healing, complications and return to OR. A total of 35 patients met inclusion criteria. There were 28 patients in the PINS IN group with an average age of 12.8 years, of which 82% male and 43% fractured their right olecranon. There were 7 patients in the PINS OUT group with an average age of 12.6 years, of which 57% were male and 43% fractured their right olecranon. All patients in both groups were treated with open reduction internal fixation with a tension band-technique. In the PINS IN group, 64% were treated with 2.0 k-wires and various materials for the tension band (82% suture, 18% cerclage wire). In the PINS OUT group, 71% were treated with 2.0 k-wires and all were treated with sutures for the tension band. The PINS IN group were faster to mobilize (3.4 weeks (range 2-5 weeks) vs 5 weeks (range 4-7 weeks) p=0.01) but had a significantly higher complications rate compared to the PINS OUT group (6 vs 0, p =0.0001) and a significantly higher return to OR (71% vs 0%, p=0.0001), mainly for hardware irritation or limited range of motion. All fractures healed in both groups within 7 weeks. Pediatric olecranon fractures treated with a suture tension-band technique and k-wires left percutaneously is a safe and alternative technique compared to the traditional buried k-wires technique. The PINS OUT technique, although needing longer immobilization, could lead to less complications and decreased return to the OR due to irritation and limited ROM

Olecranon plates used for the internal fixation of complex olecranon fractures are applied directly over the triceps tendon on the posterior aspect of the olecranon. The aim of the study is to describe the relationship of the plates and screws to the triceps tendon at the level of the olecranon. Eight cadaveric elbows were used. Dimensions of the triceps tendon at the insertion and 1cm proximal were measured. A long or a short olecranon plate was then applied over the olecranon and the most proximal screw applied. The length of the plate impinging on the tendon and the level of the screw tract on the tendon and bone were measured. The mean olecranon height was 24.3cm (22.4-26.9cm) with a tip-to-tendon distance of 14.5cm (11.9-16.2cm). The triceps tendon footprint averaged 13.3cm (11.7-14.9cm) and 8.8cm (7.6-10.2cm) in width and length, respectively. The mean width of the central tendon 1 cm proximal to the footprint was 6.8 cm. The long olecranon plate overlay over more movable tendon length than did the short plate and consequently the superior screw pierced the triceps tendon more proximally with the long plate. Using the Mann-Whitney U test, the differences were significant. The long olecranon plates encroach on more triceps tendon than short plates. This may be an important consideration for olecranon fractures with regards implant loosening or triceps tendon injury

Non-operative management of displaced olecranon fractures in elderly low demand patients is reported to result in a satisfactory outcome despite routinely producing a nonunion. The aim of this study was to assess whether there is evidence of dynamic movement of the fracture fragment during the elbow arc of movement. Five consecutive patients (≥70 years of age) with a displaced olecranon fracture (Mayo 2A) that were managed with non-operative intervention were recruited. All underwent ultrasound evaluation at six weeks and follow-up questionnaires at six months including the DASH and Oxford Elbow Score (OES). There were three women and two men with a mean age of 79yrs (range 70–88). All injuries were sustained following a fall from standing height. The mean fracture gap in extension was 22.5mm (95% CI 13.0–31.9), midflexion 21.8mm (11.6–32.0) and in deep flexion 21.8mm (10.9–32.8). Although the amount of fracture displacement varied between patients, it remained static in each patient with no significant differences observed throughout the arc of motion (ANOVA p=0.99). The six-month median DASH score was 7.5 (IQR range, 4.2–39.3) and the OES was 44.0 (29.0–47.5). Four out of the five patients were satisfied with their function. Ultrasound evaluation of displaced olecranon fractures following non-operative management suggests the proximal fragment may function as a sesamoid type bone within the triceps sleeve. This could explain how a functional arc of movement with a minimum level of discomfort can usually be expected with non-operative management in select patients

Radial head fractures are among the most common fractures around the elbow. Radial head arthroplasty is one of the surgical treatment options after complex radial head fractures. This surgery is usually done under general anaesthesia. However, there is a recent anaesthetic technique - wide awake local anaesthesia no tourniquet (WALANT) - that has proven useful in different surgical settings, such as in distal radius or olecranon fractures. It allows a good haemostatic control without the use of a tourniquet and allows the patient to actively collaborate during the surgical procedure. Furthermore, there are no side effects or complications caused by the general anaesthesia and there's an earlier patient discharge. The authors present the case of a seventy-six-year-old woman who presented to the emergency department after a fall from standing height with direct trauma to the left elbow. The radiological examination revealed a complete intra-articular comminuted fracture of the radial head (Mason III). Clinical management: The patient was submitted to surgery with radial head arthroplasty, using WALANT. The surgery was successfully completed without pain. There were no intra or immediate post-operative complications and the patient was discharged on the same day. Six weeks after surgery, the patient had almost full range of motion and was very pleased with the functional outcome, with no limitations on her activities of daily living. The use of WALANT has been expanded beyond the hand and wrist surgery. It is a safe and simple option for patients at high risk of general anaesthesia, allowing similar surgical outcomes without the intraoperative and postoperative complications of general anaesthesia and permitting an earlier hospital discharge. Furthermore, it allows the patient to actively collaborate during the surgery, providing the surgeons the opportunity to evaluate active mobility and stability, permitting final corrections before closing the incision

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 a contoured Locking Compression Plate (LCP) with a conventional plating method (one-third tubular plate) in a cadaveric comminuted olecranon fracture model with standardized osteotomy, and. to evaluate the LCP fixation method in a prospectively included group of patients with complex olecranon fractures using validated outcome scores. In the biomechanical study, five matched pairs of cadaveric elbows were randomly assigned for fixation by either LCP or a conventional plating method. Specimens were mounted to a custom-made testing bench and subjected to cyclic loading until failure occurred while measuring gapping at the osteotomy site. In the clinical study, twenty-one patients treated with LCP for complex olecranon fractures had a mean follow up of 20 months (3–39 months) and functional and patient rated outcome were evaluated. In the biomechanical study, there was no significant difference in fixation stiffness and strength between one third tubular plating and LCP (p > 0.05). In the clinical study, the mean time to union of the fracture was 6 months (2–28 months). According to the Mayo Elbow Performance Index (MEPI) most patients had a good or excellent outcome. No patients reported difficulty with activities of daily living. Physical capacity showed minimal loss of stability and strength. Six patients had their hardware removed. Technical ease of application and advantageous features of the LCP -such as unicortical screw fixation and improved holding power in osteopenic bone- make it a good alternative implant for comminuted olecranon fractures

Aims: Tension band wiring is a widely accepted method for internal þxation of olecranon fractures. Plate þxation is suggested for the more complex olecranon fractures, but little is known about the speciþc risk factors for failure of tension band wiring. The aim of this study was to analyze the inßuence of fracture comminution, associated elbow instability and fracture extension into the coronoid process on the outcome of tension band wiring for olecranon fractures. Methods: From 1996 to 1998, forty-four olecranon fractures were treated consecutively at out institution using tension band wiring. All patients returned for a clinical and radiographic exam performed by two observers independent of the treating surgeon. Pain and satisfaction were determined using visual-analogue scales (VAS) and clinical results were graded using the Mayo Elbow Performance Score (MEPS) and the DASH questionnaire. Patients were followed for 3 to 6 years. Results: At most recent follow-up, the mean VAS score for pain was 2.0, mean extension was 3.6û and mean ßexion was 137.2û. According to the MEPS the results were graded as good or excellent in 78% of the patients. Five patients were disabled for activities of daily living according to the DASH questionnaire. All but one fracture healed. Fracture comminution did not affect the outcome. Worse results were associated with elbow instability and fracture extension into the coronoid. Conclusions: Tension band wiring provided satisfactory results for the treatment of olecranon fractures in the presence of fracture comminution, but worse results were obtained in the presence of elbow instability and fracture extension into the coronoid

Tension band wire fixation continues to be the most popular method of fixation for displaced olecranon fractures despite several biomechanical studies questioning the validity of the tension band concept. Our aim was to compare the outcome of the tension band wire (TBW) method with plate fixation. 58 consecutive olecranon fractures underwent internal fixation in 58 patients between September 2000 and December 2004. There were 30 male and 28 female with a mean age at the time of surgery of 52.5 years for the TBW group (range 19 to 88) and 46.1 for the plate group (range 19 to 72). Patients were excluded if they were less than 16 years of age. Choice of fixation was based on surgeon preference, fracture pattern and presence of associated injuries. 43 patients were managed with the AO tension band technique and 15 with plate fixation. Clinical assessment and functional analysis was performed using Helm’s scoring system. Radiographic assessment was performed to assess the quality of reduction. All fractures were displaced and classified according to Colton’s classification. Mean follow up was 13 months (range 6 to 18) and similar for the two groups. For the TBW group 41 (95 %) had a fair or good result. 27 (62.8%) patients had symptomatic metal prominence requiring implant removal. In the plate fixation group 14 (94%) had a fair or good functional result despite having more complex fractures. Only 2 (18%) patients required implant removal for symptomatic metalwork, including one failure due to a technical problem. Similar functional results were seen with plating and tension band wiring of displaced olecranon fractures. Despite meticulous technique, tension band wire fixation still has an unacceptably high complication rate with symptomatic metal prominence requiring further surgery. To avoid this problem, we recommend plating, even for the more simple olecranon fractures

The aim of this study was to document both the short and long term outcome of isolated displaced olecranon fractures treated with primary non-operative intervention. We identified from our prospective trauma database all patients who were managed non-operatively for a displaced olecranon fracture over a 13-year period. Inclusion criteria included all isolated fractures of the olecranon with >2 mm displacement of the articular surface. Demographic data, fracture classification, management, complications and subsequent surgeries were recorded. The primary short-term outcome measure was the Broberg and Morrey Elbow score. The primary long-term outcome measure was the DASH score. There were 43 patients in the study cohort with a mean age of 76 yrs (40–98). A low energy fall from standing height accounted for 84% of all injuries, with ≥1 co-morbidities documented in 38 (88%) patients. At a mean of 4 months (range, 1.5–10) following injury the mean Broberg and Morrey score was 83 (48–100), with 72% achieving an excellent or good short-term outcome. Long-term follow-up was available in 53% (n=21) patients, with the remainder deceased. At a mean of six years (2–15) post injury, the mean DASH score was 2.9 (0–33.9), the mean Oxford Elbow Score was 47 (42–48) and overall patient satisfaction was 91% (n=21). We have reported satisfactory short-term and longer-term outcomes following the non-operative management of isolated displaced olecranon fractures in older lower demand patients. Further work is needed to directly compare operative and non-operative management in this patient group

Olecranon fractures account for 20% of elbow fractures. Displaced fractures can be treated by several methods – Tension Band Wiring (TBW), Open Reduction and Internal Fixation with a plate (ORIF) or conservative measures. Studies from UK specialist centres have demonstrated infection rates of up to 15% and metal ware removal rates of up to 80%. In addition studies have shown that conservative treatment provides a good function and pain relief in the elderly and infirm. We aimed to look at all displaced olecranon fractures within our unit over a 4 year period and analyse their case notes for patient features, age stratification, treatment methods, complications and outcomes. We also aimed to compare our results to outcomes in studies published by specialist centres. All olecranon fractures admitted to our unit in calendar years 2007–2010 were identified from our trauma database. Case sheets were analysed for patient's age, co-morbidities, treatment, complications and outcome. X-rays were analysed to classify the fractures and assess outcome of treatment. 71 patients were identified, Male: Female = 33:38. Age range was 7–93, mean was 62.8 years. Treatment used – TBW 42 (59.1%), ORIF 9 (12.7%), and Conservative 20 (28.2%). In the surgical group of 51 patients there were 4 infections (7.8%). There were no incidences of nerve palsy. Metalware was removed in 15 patients (29.4%) – for TBW this was 11/42 (26.25%) and ORIF 4/9 (44.4%) – however the difference was not significant (p=0.06). The conservative group had no complications. In our study group we have demonstrated a lower infection rate and a far lower rate of metal ware removal than published studies. We have a high rate of patients treated conservatively who do well. Further work is being performed into the functional outcome of the whole group

Study of olecranon fractures in childhood and evaluation of the treatment approach. During a 20 year period, 64 children with olecranon fractures were treated in our clinic. 51 children (41 males and 10 females) aged from to 2.5 to 14 years were reviewed. The follow up period was 1 to 20 years(average 9 years). Coexisting skeletal injury appeared in 31 patients. 36 children were treated conservatively while we follow operative treatment (open reduction and stabilization with Kirschner wires with or without tension-band or screws) in 15 children. At the very last examination 2 children complained of mild pain during weather changes. Elbow extension was reduced from 5° to 15° in 6 patients and elbow flexion was reduced up to 5° in 3 patients. Pronation shortage was observed in 3 patients from 5° to 20° and a 10° supination shortage was observed in 1 patient. One case with pronation – supination shortage (40° and 70° respectively) while persisting subluxation of radial head was in 1 patient. The greatest degree of mobility limitation was observed in patients with comminuted fractures and associated injuries. Transient paresis of the radial nerve was observed in 1 patient. The usual therapeutic approach to olecranon fractures is conservative. In cases of displaced fractures, especially when the intraarticular displacement is greater than 3mm, surgical approach is indicated. Complications tend to occur more frequently among those cases with associated injuries. Olecranon paramorphosis in varus needs special attention since it usually coexists with radial head dislocation

Background: To improve the primary operative treatment of complex olecranon fractures we searched for new conclusive parameters. We hypothesized that the intermediate fragment plays a critical role for precise restoration of the trochlear notch contour and good outcome of initial operative treatment. Methods: 58 patients (26 female, 32 male; mean age 55 years) with multi-fragmentary olecranon fracture were identified in a seven-year-period from trauma unit files at two European Level 1 trauma institutions. Retrospective review of all operative reports and radiographs/computed tomography scans identified patients with an intermediate fragment. Results: 28 patients were treated with stable internal fixation using figure-of-eight tension-band wire fixation and 30 patients using posterior plate osteosynthesis with and without intramedullary screw. An intermediate fragment was seen in 36 patients (62 %). In 17 of these 36 patients (47 %), the intermediate fragment was described in operative report. Twelve of these patients (71 %) were treated with single posterior plate with/without an intramedullary screw, and five patients (29 %) with figure-of-eight tension-band wire fixation. Conclusion: Fracture analysis identified an intermediate fracture fragment in the majority of patients with complex olecranon fractures. In diagnostic work up a CT scan should be used to assess the fracture pattern and to detect an intermediate fragment. This study suggests that identification, desimpaction and anatomic reduction of the intermediate fragment are critical preconditions for anatomic restoration of the trochlear notch and good functional results. Precise description of the fracture pattern including presence of an intermediate fragment in the operative report is recommended

Purpose: Tension band wiring is the most common surgical procedure for fixation of fractures of the Olecranon, but it is associated with high rate of metal work complications and implant failure leading to re-operation. Method: We present a new fixation technique for olecranon fractures that avoids reoperation to remove hardware as compared with the standard fixation technique with Kirschner wires and tension band wiring as advocated by the AO technique. We describe fixation of displaced transverse and oblique olecranon fractures with anchor sutures, each of which has two pairs of suture strands. Prior to the insertion of the anchor sutures, the fracture is reduced through a standard open approach. Results: Twelve patients have been treated with this technique so far, with a mean follow-up of 6 months. The mean age of the patients was 46.7 years (range 14–75 yrs). We have followed all these patients till union of the fractures. No immediate complications have been noted. Radiographic results are good, with no loss of reduction. Conclusion: This technique avoids the need for reop-eration for hardware removal without compromising the quality of reduction. It may be argued that anchor sutures may cost more than tension band wiring which is a very low cost procedure. At the same time, we should also consider the future cost involved because of reoperation rate and morbidity. Our newly described technique would be particularly useful in dealing with olecranon fractures in children where it is undesirable to cross the physeal plate by metal work. It would also be of great value in dealing with intra articular distal humeral fractures where fixation is planned initially but conversion to total elbow replacement becomes essential intra-operatively. In such cases an olecranon osteotomy can be fixed by this technique, even in presence of a total elbow replacement
