The third part is in the bone tunnel in the coronoid process and is fixed at 15 mm. We measured the displacement and angulation possible at the elbow before and after the reconstruction. In stage 1, the lateral collateral ligament is partially or completely disrupted (the ulnar part is disrupted). Clin Orthop Relat Res. This cohort may be medically unsuitable for prolonged surgery or assessed as not able to tolerate external fixation. Doornberg JN, Guitton TG, Ring D; Science of Variation Group. In 3B the anterior bundle is ruptured and in 3C the elbow remains unstable after reduction even in 90 degrees of flexion [22]. Furthermore, the severity of injury to the ligaments being repaired may necessitate augmentation with free tendon graft or skeletal support with hinged external fixators. Operative treatment is therefore indicated.

This is often due to interposed soft tissues or alternatively to ligamentous instability. Unstable elbow dislocations J Shoulder Elbow Surg 2008; 17: 281-86. Most commonly, dynamic stabilisation is achieved with soft tissue repair or reconstruction or hinged external fixation. KE Cramer. 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]. A simple elbow dislocation that spontaneously re-dislocates following closed reduction and appropriate stabilising manoeuvres (elbow flexion and forearm pronation) is a rare problem. 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. In addition, the graft remains attached to its insertion on the olecranon and remains vascularised. 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. Acute Simple Elbow Dislocations . mechanism for posterolateral dislocation . 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. A 4 mm tunnel is then drilled beginning at the tip of the coronoid process and traversing the ulna to exit through the dorsal cortex of the ulna (Figure 4). 2008 Sep 19;1(1):168. doi: 10.1186/1757-1626-1-168. A posterior longitudinal incision is made from the tip of the olecranon and extended 10 cm proximally. 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. In unstable elbow dislocation, PLDL and PMDL are caused by different mechanisms following damage to different structures. When the head of the humerus dislocates, the socket bone (glenoid) and the ligaments in the front of the shoulder are frequently injured. We think that this is a responsible approach to take before introducing a new procedure to patients. 1. the display of certain parts of an article in other eReaders. COVID-19 is an emerging, rapidly evolving situation. The ePub format is best viewed in the iBooks reader. Shoulder dislocation—Severe injury, or trauma, is often the cause of an initial shoulder dislocation. Therefore, different strategies are needed to ameliorate the dislocation and instability. The OK method has a reported risk of distal humerus fracture [28] and heterotopic ossification [29]. 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. The mean distance (D) from coronoid tip to triceps insertion on the olecranon was 34 mm. We have demonstrated that it is technically feasible and easy to perform with minimal equipment requirements or costs. The importance of the anterior band of the MUCL and the LUCL has been highlighted by O’Driscoll [23]. Therefore, different strategies are needed to ameliorate the dislocation and instability. The vast majority of simple dislocations can be reduced closed with sedation and will remain reduced and stable [4]. These observations are consistent with the few prior papers that present data on unstable, simple elbow dislocations. Additionally the repair or reconstruction of the collaterals must be anatomical to allow unrestricted elbow flexion and extension around its axis of rotation. The graft tracked nicely in the trochlea grove with no impingement.

Please enable it to take advantage of the complete set of features! Lateral radiograph of an elbow with superimposed schematic of the reconstruction. The pathomechanics of dislocation proposed by Horii describes sequential failure of the soft tissues from lateral to medial. There are potential drawbacks specific to this technique. There are three common ways that a shoulder can become unstable. Simple dislocations typically do not require surgery. 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. Unstable simple elbow dislocation (USED) repair is challenged by the maintenance of joint reduction; hence, primary repair or reconstruction of disrupted ligaments is required to maintain the congruency and allow early motion of the elbow. The distance A was measured with callipers. Information for Authors/Reviewers. 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. We describe a new intra articular reconstruction that utilises a slip of triceps tendon to provide immediate stability to the elbow. The goal of reconstruction is early mobilization within a stable arc of motion. Abstract – Introduction: A small proportion of simple elbow dislocations are grossly unstable and joint congruence is not maintained after reduction. This represents the diameter of our proposed osseo-tendonous ring. The mean length of the tendon insertion A was 22 mm. In 3A the posterior bundle of the medial ulnar collateral ligament (MUCL) is ruptured but the anterior bundle is intact. Received 2015 May 24; Accepted 2015 Jul 3. (2001) The unstable elbow. The dislocations may be complex or simple. We have demonstrated that it is technically feasible and easy to perform with minimal equipment requirements or costs. If patients complains of any new symptoms re Xray!!! 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. 2009 Aug;33(4):1141-7. doi: 10.1007/s00264-008-0624-x. When an elbow dislocation is associated with a fracture this injury has been termed a complex dislocation [ 5, 6, 7 ]. 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).

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. Int Orthop. However when a fracture has occurred, the elbow may remain unstable if surgery is not performed. Complex and Unstable Simple Elbow Dislocations: A Review and Quantitative Analysis of Individual Patient Data. Following the reconstruction it was not possible to re-dislocate the elbow. These symptoms occur during the act of extension and supination, especially when an axial load is applied through the upper extremity. NLM 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]. Department of Orthopaedic surgery, St Georges NHS Foundation Trust Blackshaw Road Tooting, London Three bones come together to make up the elbow. 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 . The elbow is the second most commonly dislocated joint in adults[2]. Epub 2012 Dec 18. In this rare situation operative treatment is indicated. Elbow held in 45 degree of flexion; Olecranon is prominent posteriorly The lateral ulnar collateral ligament and extensor origin reattachment can be easily performed. 1–3 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. The posterior aspect of the humerus is then visible through the triceps split. These injuries often require surgical treatment to render the elbow stable enough to allow early motion. Ozel O et al. The incidence of simple elbow dislocations is 5–6 per 100,000 . NIH Prior to the reconstruction greater than 30 mm of joint distraction and 90 degrees varus or valgus angulation was possible. The second (B) is the intra-articular portion which passes from the olecranon through the olecranon fossa and to the coronoid. Ligamentous repair can be indicated in high demand patients or if the elbow remains unstable following a closed reduction. A small proportion of simple dislocations are grossly unstable and do not remain reduced with standard non-operative treat- ment. We propose a new surgical technique and assess its feasibility in a cadaveric study. 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]. Epub 2008 Aug 2. 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. Additionally the common flexor and extensor origins are frequently avulsed from the medial and lateral epicondyles. A spectrum of instability, Armstrong AD, Ferreira LM, Dunning CE, Johnson JA, King GJ (2004), The medial collateral ligament of the elbow is not isometric: an in vitro biomechanical study, Complications of hinged external fixation compared with cross-pinning of the elbow for acute and subacute instability, Elbow dislocation with complete triceps avulsion, Rosenberg TD, Franklin JL, Baldwin GN, Nelson KA (1992), Extensor mechanism function after patellar tendon graft harvest for anterior cruciate ligament reconstruction, Heterotopic ossification after the Outerbridge-Kashiwagi procedure in the elbow, http://creativecommons.org/licenses/by/4.0. This technique utilises the harvest of a central strip of triceps tendon which is distally based and remains attached at its insertion. Good results have been reported [19, 20]. Surgical management of unstable elbow dislocation without intra-articular fracture. Most simple elbow dislocations can be reduced closed with sedation and will remain reduced and stable . 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). It does not prove clinical applicability of the technique or superiority to current conventional methods.

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. When dislocations are associated with fractures, they are designated as complex. ### 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. Despite reduction and fixation of associated fractures, significant soft-tissue injury that occurs as a result of dislocation may result in residual instability. Complex fracture-dislocations of the elbow are treated surgically and are challenging injuries to manage. 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. USA.gov. The mean length of triceps tendon available for use was 106 mm.

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. In all the elbows there was sufficient triceps tendon length to perform the technique. The posterior olecranon fossa is cleared and a fenestration is made with a 4 mm drill to access the anterior joint space (Figure 3). We believe that our novel technique elegantly avoids many of the problems associated with current methods. We describe a new intra articular reconstruction that utilises a slip of triceps tendon to provide immediate stability to the elbow. The reported annual incidence of simple … Stage 2 is the anterior capsular structures. Elbow dislocations constitute approximately 10–25% of all elbow injuries and approximately 6.8% of all treated fractures or dislocations. 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. Fracture-dislocations of the elbow are devastating injuries. Elbow stability must be restored by addressing the specific … Posterior view of the graft in its final position. The isometric relationship between the articular proximal ulna and the axis of rotation of the elbow is restored allowing a full range of movement. 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. The tendon strip is divided proximally at the musculotendonous junction and longitudinally to its insertion. The surgeon must maintain a high index of suspicion when evaluating an elbow dislocation to avoid missing critical associated injuries. Posterior dislocation of the elbow associated with fracture of the radial head and olecranon, and with medial collateral ligament disruption: A case report. Repetitive strain—… In this rare situation operative treatment is indicated. Swelling may be severe; Displaced equilateral triangle of olecranon and epicondyles (undisturbed in supracondylar fracture) Posterior dislocation. The amount of soft tissue injury to the flexor-pronator and extensor origins is correlated with the instability of the elbow and likelihood of the elbow to redislocate [ 1 ]. 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. Ligamentous repair of acute lateral collateral ligament rupture of the elbow, Outerbridge-Kashiwagi’s method for arthroplasty of osteoarthritis of the elbow—44 elbows followed for 8–16 years, Zantop T, Ferretti M, Bell KM, Brucker PU, Gilbertson L, Fu FH (2008), Effect of tunnel-graft length on the biomechanics of anterior cruciate ligament-reconstructed knees: intra-articular study in a goat model, Qi L, Chang C, Jian L, Xin T, Gang Z (2011), Effect of varying the length of soft-tissue grafts in the tibial tunnel in a canine anterior cruciate ligament reconstruction model, Long-term sequelae of simple dislocation of the elbow, Rafai M, Largab A, Cohen D, Trafeh M (1999), Pure posterior luxation of the elbow in adults: immobilization or early mobilization. | Failure to restore joint congruence is likely to be associated with stiffness, reduced range of motion, instability and future degenerate change [13]. Home; About Journals. 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]. The distance between the tip of the coronoid and the triceps insertion on the olecranon was measured with callipers. A small incision is made over the tip of the drill at the point where it penetrates the dorsal cortex of the ulna. These bones are the arm bone (humerus) and two forearm bones (radius and ulna). Only 2 mm of joint distraction and 10 degrees of varus or valgus angulation were possible with the triceps graft fixed in position. The most common patient complaints/symptoms are recurrent popping, clicking, clunking, or locking, accompanied by a sense of instability in the elbow. Drilling of the graft tunnel in the ulna through the olecranon fossa. Static stabilisation of the elbow is relatively technically simple and has been described with the use of external fixation or trans-articular pinning. EPIDEMIOLOGY AND TREATMENT OF MONTEGGIA LESION IN ADULTS: SERIES OF 44 CASES. Current treatment concepts of simple, that is, stable, or complex unstable elbow dislocations are outlined by means of case reports. Anterior view of the graft in its final position. HHS This type of injury can damage the bone and ligaments that surround the elbow joint and work to keep it stable. 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]. Current treatment concepts of simple, that is, stable, or complex unstable elbow dislocations are outlined by means of case reports. "Terrible Triad" injury describes unstable joint consisting of: Elbow dislocation; Radial head fracture; Coronoid fracture; Clinical Features. Elbow stability must be restored by addressing the specific components of the injury. We would also advocate this technique in the “resource poor” environment. 2 Department of Radiology, School of Medicine, Keimyung University, … 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. Central strip of triceps tendon harvested and whip stitched. All 20 cadaveric elbows were assessed. Micic I, Kim SY, Park IH, Kim PT, Jeon IH. Methods: We assessed 20 cadaveric elbows, measuring the length of triceps tendon available and required to complete the reconstruction. The primary disadvantage of this static approach is in the tendency of the elbow to stiffen following severe injury. - ref: Unstable elbow dislocations and fracture-dislocation: Temporary trans-articular fixation. Early active range of motion within 1–2 weeks has been shown to be safe and produce good outcomes compared with prolonged immobilisation [5]. You may notice problems with Gently move elbow through its range of motion. 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. This gives a calculated tendon length (1/2πD) of 53 mm for the intra-articular portion (B) of the graft. This completes the osseo-tendonous ring (coronoid, olecranon and triceps tendon) giving immediate stability (Figures 5 and and6).6). Evaluate stability following reduction. Dynamic stabilisation aims to avoid the problems of immobilisation by allowing early functional rehabilitation. Introduction: A small proportion of simple elbow dislocations are grossly unstable and joint congruence is not maintained after reduction. MH, TB and JB declare no conflict of interest in relation with this paper. This study evaluates the technique and results of temporary transarticular fixation of the unstable elbow, a previously unreported acute … Patients with PLRI may present with a spectrum of different symptoms ranging from vague pain in the elbow to recurrent posterolateral dislocations. Stage 3 is rupture of the medial collateral ligament and is divided into three. Søjbjerg JO, Helmig P, Kjaersgaard-Andersen P (1989) Dislo- cation of the elbow: an … Management of unstable elbow fractures muscle groups, are any muscles crossing the elbow joint that exert a compressive force on the joint[1]. A severe first dislocation can lead to continued dislocations, giving out, or a feeling of instability. A small proportion of simple dislocations are grossly unstable and do not remain reduced with standard non-operative treatment. A small proportion of simple dislocations are grossly unstable and do not remain reduced with standard non-operative treatment. Results are generally good, although a small percentage of patients may develop chronic instability. Most simple elbow dislocations can be reduced closed with sedation and will remain reduced and stable. An elbow dislocation is defined as “simple” if there is no associated fracture. The longitudinal split in the triceps tendon is then closed with sutures.
