The slip of harvested tendon is then whip stitched with the tails of the suture left long at the free end of the tendon (Figure 2). Radial nerve palsy after the use of an adjuvant hinged external fixator in a complex fracture-dislocation of the elbow: a case report and review of the literature. In unstable elbow dislocation, PLDL and PMDL are caused by different mechanisms following damage to different structures. The distance between the tip of the coronoid and the triceps insertion on the olecranon was measured with callipers. Mark Harris, Timothy Bishop, and Jason Bernard. mechanism for posterolateral dislocation . Acta Ortop Bras. [26] Pugh DM, Wild LM, Schemitsch EH, King GJ, McKee MD. When dislocations are associated with fractures, they are designated as complex. 2008 Sep 19;1(1):168. doi: 10.1186/1757-1626-1-168. We propose a new surgical technique and assess its feasibility in a cadaveric study. 2016 Jan-Feb;24(1):48-51. doi: 10.1590/1413-785220162401152249. The central triceps strip is passed through a fenestration made in the olecranon fossa and fixed to the coronoid process to construct a complete osseo-tendonous ring (coronoid, olecranon and triceps tendon) that holds the ulna congruent with the trochlea of the distal humerus. Acute Simple Elbow Dislocations . ### Pathoanatomy The pathoanatomy of an elbow dislocation can be thought of as a disruption of the circle of soft tissue or bone, or both, that begins on the lateral side of the elbow and progresses to the medial side in three stages (Fig. We think that this is a responsible approach to take before introducing a new procedure to patients. Poglia P, Wehrli L, Steinmetz S, Zermatten P. J Med Case Rep. 2016 May 11;10(1):121. doi: 10.1186/s13256-016-0904-9. "Terrible Triad" injury describes unstable joint consisting of: Elbow dislocation; Radial head fracture; Coronoid fracture; Clinical Features. This is exacerbated by prolonged immobilisation following dislocation and is associated with poorer outcomes than early functional rehabilitation [14–17]. Most commonly, dynamic stabilisation is achieved with soft tissue repair or reconstruction or hinged external fixation. Results are generally good, although a small percentage of patients may develop chronic instability. Treatment of posteromedial and posterolateral dislocation of the acute unstable elbow joint: a strategic approach Furthermore, the severity of injury to the ligaments being repaired may necessitate augmentation with free tendon graft or skeletal support with hinged external fixators. The reported annual incidence of simple … The most common patient complaints/symptoms are recurrent popping, clicking, clunking, or locking, accompanied by a sense of instability in the elbow. It has been shown that in unstable simple elbow dislocation most if not all the primary soft tissue stabilisers of the joint are ruptured [21]. This is primarily a feasibility study to demonstrate that our idea is technically possible. Simple elbow dislocations are usually treated conservatively. A small proportion of simple dislocations are grossly unstable and do not remain reduced with standard non-operative treatment. Complex fracture-dislocations of the elbow are treated surgically and are challenging injuries to manage. The OK method has a reported risk of distal humerus fracture [28] and heterotopic ossification [29]. We are experimenting with display styles that make it easier to read articles in PMC. If the elbow remains unstable, application of a hinged elbow external fixator or repair of the medial collateral ligament must be considered. Clin Orthop Relat Res. Home; About Journals. We chose 15 mm as the length of graft in the tunnel because this has been reported as a safe length in anterior cruciate ligament reconstruction [11, 12]. The dislocation is classified as simple or complex depending on the presence or absence of an associated fracture [1]. Elbow held in 45 degree of flexion; Olecranon is prominent posteriorly The lateral ulnar collateral ligament and extensor origin reattachment can be easily performed. Only 2 mm of joint distraction was and 10 degrees of varus or valgus angulation were possible with the triceps graft fixed in position. The bones have very distinct shapes so that they fit together closely. Stage 1 begins with the lateral collateral ligament complex (LCLC) which is comprised of the lateral ulnar collateral ligament (LUCL), the radial … The elbow joint is further stabilized by ligaments that helps hold the bones together. Most simple elbow dislocations can be reduced closed with sedation and will remain reduced and stable . However, there is no single protocol to guide the surgeon on which structures should be repaired and in what order.

Elbow instability is a looseness in the elbow joint that may cause the joint to catch, pop, or slide out of place during certain arm movements. Failure to restore joint congruence is likely to be associated with stiffness, reduced range of motion, instability and future degenerate change [13]. The elbow is flexed so that the tip of the coronoid process is visible through the fossa. The tendon strip is divided proximally at the musculotendonous junction and longitudinally to its insertion. These observations are consistent with the few prior papers that present data on unstable, simple elbow dislocations. 1-A). KE Cramer. The elbow is the second most frequently dislocated large joint. A posterior longitudinal incision is made from the tip of the olecranon and extended 10 cm proximally. In this rare situation operative treatment is indicated. This is often due to interposed soft tissues or alternatively to ligamentous instability. Complex fracture-dislocations of the elbow are treated surgically and are challenging injuries to manage. In this scenario several operative techniques have been described including open collateral ligament repair or reconstruction [6], fixed or hinged external fixators [7] and trans-articular pinning [8, 9]. Hinged external fixators must be applied exactly aligned with the axis of rotation of the joint and are associated with high rates of complications, particularly infection [25]. Radiographs are negative in simple dislocations. Elbow dislocation which required an extension block splint over 45°to maintain reduction was considered as an unstable elbow dislocation as previously described by Morrey and O'Driscoll [15, 21]. Repetitive strain—…  |  18. Static stabilisation of the elbow is relatively technically simple and has been described with the use of external fixation or trans-articular pinning. In 3A the posterior bundle of the medial ulnar collateral ligament (MUCL) is ruptured but the anterior bundle is intact. Our data suggest that unstable simple elbow dislocation occurs in some elderly women after low energy falls and some younger patients with high energy injury mechanisms. These patients are typically offered trans-articular pinning or non-operative treatment and it is in this setting that we believe our new technique will offer them most advantage. We have demonstrated that it is technically feasible and easy to perform with minimal equipment requirements or costs. Unstable elbow dislocations and fracture-dislocations: Temporary transarticular fixation Cramer, Kathryn E. ; Moed, Berton R. ; Karges, David E. ; Watson, J. Tracy Journal of Orthopaedic Trauma: February 2000 - Volume 14 - Issue 2 - p 120 Lateral radiograph of an elbow with superimposed schematic of the reconstruction. In addition, the graft remains attached to its insertion on the olecranon and remains vascularised. Cite this article as: Harris M, Bishop T & Bernard J (2015) Unstable elbow dislocations: the description and cadaveric feasibility study of a new surgical technique. Malpositioning of the isometric LCL or the non-isometric MUCL [24] will result in stiffness or instability depending on the position of the elbow during tensioning of the repair. Micic I, Kim SY, Park IH, Kim PT, Jeon IH. It most often occurs as a result of an injury — typically, a previous elbow dislocation. The ePub format uses eBook readers, which have several "ease of reading" features In stage 1, the lateral collateral ligament is partially or completely disrupted (the ulnar part is disrupted). This completes the osseo-tendonous ring (coronoid, olecranon and triceps tendon) giving immediate stability (Figures 5 and ​and6).6). The triceps tendon may be at risk of donor site morbidity including pain and weakness similar to that seen following patella tendon harvest for ACL reconstruction [27]. You may notice problems with All 20 cadaveric elbows were assessed.  |  The vast majority of simple dislocations can be reduced closed with sedation and will remain reduced and stable [4]. A small proportion of simple dislocations are grossly unstable and do not remain reduced with standard non-operative treatment. Fifteen had open reduction and ligament repair (3 with ancillary hinged external fixation), and 2 infirm patients had closed reduction and cross pinning of the elbow joint. 1. We present a case report of an unstable elbow dislocation that we treated with a new surgical technique. NIH Central strip of triceps tendon harvested and whip stitched. Int Orthop. In 3B the anterior bundle is ruptured and in 3C the elbow remains unstable after reduction even in 90 degrees of flexion [22]. We present a case report of an unstable elbow dislocation that we treated with a new surgical technique. Doornberg JN, Guitton TG, Ring D; Science of Variation Group. Therefore, different strategies are needed to ameliorate the dislocation and instability. This site needs JavaScript to work properly. Department of Orthopaedic surgery, St Georges NHS Foundation Trust Blackshaw Road Tooting, London More than 30 mm of joint distraction was possible and greater than 90 degrees varus or valgus angulation was possible. elbow dislocations are the most common major joint dislocation second to the shoulder . This technique utilises the harvest of a central strip of triceps tendon which is distally based and remains attached at its insertion. the display of certain parts of an article in other eReaders. Simple Elbow Dislocation • No associated fractures • Complete or near complete capuloligamentous injury • Extensive muscle injury • Nearly always stable after reduction • No advantage to surgery if stable • No more than 2 weeks immobilization . Their healing potential may be reduced due to comorbidities such as diabetes or medications such as steroids. 1–3 If elbow congruent in sling or backslab review 5-7 days AND re Xray!!! Methods: We assessed 20 cadaveric elbows, measuring the length of triceps tendon available and required to complete the reconstruction. Operative treatment is therefore indicated. The mean distance (D) from coronoid tip to triceps insertion on the olecranon was 34 mm. The proximal ulna must be anatomically reduced and internally fixed, the radial head must be repaired or replaced, and substantial coronoid fractures must be repaired or reconstructed. Drilling of the graft tunnel in the ulna through the olecranon fossa. Following the reconstruction it was not possible to re-dislocate the elbow. Joint distraction and stressed varus and valgus angulation were recorded before and after the reconstruction with a rule and a goniometer. The tendon is pulled through the tunnel, tensioned and fixed by tying the whip stitch through a transverse 2.5 mm drill hole in the ulna. Additionally the repair or reconstruction of the collaterals must be anatomical to allow unrestricted elbow flexion and extension around its axis of rotation. The triceps tendon is only exceptionally rarely injured in simple elbow dislocation [26] and so the graft is strong and should avoid the need for additional stabilisation of the joint. If the elbow appears to subluxate or dislocate, put in a backslab with elbow flexed 90° and do check x- ray (AP / Lat). An elbow dislocation is defined as “simple” if there is no associated fracture. Deciding which of these structures to repair adds complexity to the management. There is no need for metal insertion or its subsequent removal. The length required is the sum of three sections (Figure 7). The technique was then performed on a single cadaveric elbow in which all ligamentous stabilisers were sequentially sectioned to mimic the clinical scenario of a grossly unstable elbow dislocation.

The insertion is left intact. Prior to the reconstruction gross elbow instability was demonstrated. The mean length of the tendon insertion A was 22 mm. Early active range of motion within 1–2 weeks has been shown to be safe and produce good outcomes compared with prolonged immobilisation [5]. In this rare situation operative treatment is indicated. Instr Course Lect 50:89–102. (12th Annual Meeting of the OTA); - Dislocation w/ Radial Head Frx - Dislocation + Medial Epicondyle Frx: - following closed reduction, the medial epicondyle fracture is classified with regard to displacement; Simple dislocations have an incidence of 5–6 per 100,000 [2, 3]. The torn ligament in the front of the shoulder is commonly called a Bankart lesion. Generating an ePub file may take a long time, please be patient. The first part (A) is the insertion on the olecranon. There are various operative techniques described in the literature but there is a lack of published evidence to support any one particular treatment method. Acknowledgement to Reviewers 2019 Acknowledgement to Reviewers 2018 Acknowledgement to … The feasibility of our new technique requires sufficient triceps tendon length to complete the osseo-tendonous ring. When an elbow dislocation is associated with a fracture this injury has been termed a complex dislocation [ 5, 6, 7 ]. This type of injury can damage the bone and ligaments that surround the elbow joint and work to keep it stable. Unstable elbow dislocations J Shoulder Elbow Surg 2008; 17: 281-86.

Elbow Dislocation / Instability. NLM A small proportion of simple dislocations are grossly unstable and do not remain reduced with standard non-operative treat- ment. The longitudinal split in the triceps tendon is then closed with sutures. In an unstable simple elbow dislocation, the elbow joint is not congruent or subluxes after reduction, or requires more than a 45° extension block to maintain reduction. Elbow stability must be restored by addressing the specific … most common dislocated joint in children; account for 10-25% of injuries to the elbow ; posterolateral is the most common type of dislocation (80%) demographics . SICOT J, 1, 23, 1 This gives a calculated tendon length (1/2πD) of 53 mm for the intra-articular portion (B) of the graft. Swelling may be severe; Displaced equilateral triangle of olecranon and epicondyles (undisturbed in supracondylar fracture) Posterior dislocation. is review on elbow dislocations describes ligament and bone injuries as well as the typical injury mechanisms and the main classi cations of elbow dislocations. Diagnosis of elbow fracture patterns on radiographs: interobserver reliability and diagnostic accuracy. We describe a new intra articular reconstruction that utilises a slip of triceps tendon to provide immediate stability to the elbow.  |  Elbow Dislocation: Analysis of MR Images of Stable vs. Unstable Dislocation Chul-Hyun Cho 1, Beom-Soo Kim 1, Jaehyuck Yi 2, Hoseok Lee 3 and Du-Han Kim 1,* 1 Department of Orthopedic Surgery, School of Medicine, Keimyung University, Daegu 42601, Korea; oscho5362@dsmc.or.kr (C.-H.C.); BSKim@dsmc.or.kr (B.-S.K.) If patients complains of any new symptoms re Xray!!! Following the reconstruction it was not possible to re-dislocate or sublux the ulnohumeral joint regardless of the elbow position from full extension to full flexion. In all the elbows there was sufficient triceps tendon length to perform the technique. Dynamic stabilisation aims to avoid the problems of immobilisation by allowing early functional rehabilitation. This treatment protocol has the potential to improve the suboptimal outcomes reported in the literature for such injuries. Ozel O et al. Management of simple elbow dislocations. Gently move elbow through its range of motion. Evaluate stability following reduction. The length of B is assumed to be half the circumference of the ring (1/2πD). Current treatment concepts of simple, that is, stable, or complex unstable elbow dislocations are outlined by means of case reports. The incidence of simple elbow dislocations is 5–6 per 100,000 . The osseo-tendonous ring constructed around the trochlea provides immediate stability with concentric reduction such that the difficulties of aligning the ulna with the axis of rotation of the elbow are negated. The ePub format is best viewed in the iBooks reader. We measured the displacement and angulation possible at the elbow before and after the reconstruction. A severe first dislocation can lead to continued dislocations, giving out, or a feeling of instability. The importance of the anterior band of the MUCL and the LUCL has been highlighted by O’Driscoll [23]. We have demonstrated that it is technically feasible and easy to perform with minimal equipment requirements or costs. The elbow is the second most commonly dislocated joint in adults[2]. The free ends of the whip stitch are passed through the fenestration in the olecranon fossa and through the tunnel in the ulna with the aid of a suture passer. Ligamentous repair can be indicated in high demand patients or if the elbow remains unstable following a closed reduction. Elbow instability is a “looseness” in the elbow joint that may cause the joint to catch, jam, pop, or slide out of place during certain arm movements. Prior to the reconstruction greater than 30 mm of joint distraction and 90 degrees varus or valgus angulation was possible. Although feasible on all unstable simple dislocations, further biomechanical testing including cyclic loading of the tendon would be required before the potential applicability of this technique is known. Patients with PLRI may present with a spectrum of different symptoms ranging from vague pain in the elbow to recurrent posterolateral dislocations. This represents the diameter of our proposed osseo-tendonous ring. In unstable elbow dislocation, PLDL and PMDL are caused by different mechanisms following damage to different structures. Patterns of unstable fracture-dislocations include the "terrible triad" injury of the elbow (elbow dislocation, radial head fracture, and coronoid fracture), transolecranon fracture-dislocations, and the posterior Monteggia lesion.

This study evaluates the technique and results of temporary transarticular fixation of the unstable elbow, a previously unreported acute … Posterior view of the graft in its final position. Stage 1 begins with the lateral collateral ligament complex (LCLC) which is comprised of the lateral ulnar collateral ligament (LUCL), the radial collateral ligament (RCL) and the annular ligament. Additionally the common flexor and extensor origins are frequently avulsed from the medial and lateral epicondyles. Søjbjerg JO, Helmig P, Kjaersgaard-Andersen P (1989) Dislo- cation of the elbow: an … It most often occurs as a result of an injury — typically, an elbow dislocation. Results: All 20 elbows had sufficient triceps tendon length to complete the new technique. et al. Discussion: This novel technique elegantly avoids many of the problems associated with current methods. An unstable simple elbow dislocation is most likely to have an injured MCL, LCL, and anterior capsule as well as injury to secondary elbow stabilizers with no associated fractures. A simple elbow dislocation that spontaneously re-dislocates following closed reduction and appropriate stabilising manoeuvres (elbow flexion and forearm pronation) is a rare problem. 2009 Aug;33(4):1141-7. doi: 10.1007/s00264-008-0624-x. Patterns of unstable fracture-dislocations include the "terrible triad" injury of the elbow (elbow dislocation, radial head fracture, and coronoid fracture), transolecranon fracture-dislocations, and the posterior Monteggia lesion. Seventeen patients with a posterior dislocation of the elbow and either no fracture or a minimal capsuloligamentous avulsion fracture were treated operatively for persistent redislocation after manipulative reduction. Most simple elbow dislocations can be reduced closed with sedation and will remain reduced and stable. Elbow stability must be restored by addressing the specific components of the injury. The second (B) is the intra-articular portion which passes from the olecranon through the olecranon fossa and to the coronoid. The isometric relationship between the articular proximal ulna and the axis of rotation of the elbow is restored allowing a full range of movement. Epub 2012 Dec 18. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. The third part is in the bone tunnel in the coronoid process and is fixed at 15 mm. Anterior view of the graft in its final position. COVID-19 is an emerging, rapidly evolving situation. The primary disadvantage of this static approach is in the tendency of the elbow to stiffen following severe injury. The mean total length of graft required (A + B + C) was 91 mm (Table 1). Initially we believe that the most appropriate role for this procedure is on the cohort of patients who would currently be considered unsuitable for dynamic ligamentous repair or external fixation. The next critical step is to intraoperatively assess the stability of the elbow with a range-of-motion assessment with the forearm in pronation. Elbow dislocations constitute approximately 10–25% of all elbow injuries and approximately 6.8% of all treated fractures or dislocations. However when a fracture has occurred, the elbow may remain unstable if surgery is not performed. We would also advocate this technique in the “resource poor” environment. Received 2015 May 24; Accepted 2015 Jul 3. predominantly affects patients between age 10-20 years old; Pathophysiology . It has been shown that in unstable simple elbow dislocation most if not all the primary soft tissue stabilisers of the joint are ruptured . Fracture-dislocations of the elbow are devastating injuries. The goal of reconstruction is early mobilization within a stable arc of motion. The pathomechanics of dislocation proposed by Horii describes sequential failure of the soft tissues from lateral to medial. Stage 2 is the anterior capsular structures. Thus the joint is stabilised and a normal relationship between the ulna and the elbow axis of rotation is maintained throughout a full range of motion. Stage 3 is rupture of the medial collateral ligament and is divided into three. 8 , 9 Cases J. HHS Three bones come together to make up the elbow. We describe a new intra articular reconstruction that utilises a slip of triceps tendon to provide immediate stability to the elbow. The distance B was calculated on the basis of an observation that a line drawn from the tip of the coronoid to the tip of the olecranon (D) passes through the axis of rotation of the elbow. The graft tracked nicely in the trochlea grove with no impingement. By Gregory J. Zeiders, DO, and Minoo K. Patel, MBBS, MS, FRACS Introduction omplex fracture-dislocations of the elbow can often be either irreducible or unstable, with an inability to hold the reduction or with the delayed development of sub- luxation or dislocation. Shoulder dislocation—Severe injury, or trauma, is often the cause of an initial shoulder dislocation. Complex and Unstable Simple Elbow Dislocations: A Review and Quantitative Analysis of Individual Patient Data. These symptoms occur during the act of extension and supination, especially when an axial load is applied through the upper extremity. (2001) The unstable elbow. 2. - ref: Unstable elbow dislocations and fracture-dislocation: Temporary trans-articular fixation. 2 Department of Radiology, School of Medicine, Keimyung University, … Results after closed treatment, Simultaneous reconstruction of both medial and lateral collateral ligament complexes for recurrent instability of elbow dislocation: a case report, Treatment of unreduced elbow dislocations with hinged external fixation, Schippinger G, Seibert FJ, Steinbock J, Kucharczyk M (1999). When the head of the humerus dislocates, the socket bone (glenoid) and the ligaments in the front of the shoulder are frequently injured. Broadly speaking these can be divided into techniques which maintain the reduction by static or dynamic means. The posterior aspect of the humerus is then visible through the triceps split. The elbow is the second most commonly dislocated major joint in the body after the shoulder, with an annual incidence of 6.1 dislocations per 100 000 population. The triceps tendon is exposed and a 4 mm wide central strip extending proximally from olecranon to the musculotendonous junction is marked out (Figure 1). The pathomechanics of dislocation proposed by Horii describes sequential failure of the soft tissues from lateral to medial. USA.gov. There is an argument for static reduction particularly trans-articular pinning in patients who are not fit for more prolonged or technically difficult surgery or are being treated in “resource poor” environments [18]. Access to the anterior aspect of the joint through a window in the olecranon fossa is described in the Outerbridge-Kashiwagi (OK) method for the debridement of osteophytes in degenerative joint disease [10].
