Management of the Essex-Lopresti Injury

To Reconstruct or Not: A Case of Acute Reconstruction of the Forearm Interosseous Membrane with CMC Mini Tight Rope

Introduction

Essex Lopresti fractures are rare injuries of the forearm. Extent of damage to the interosseous membrane (IOM) in this setting is variable and can lead to disabling sequelae when not recognized and managed appropriately. While chronic reconstruction for longitudinal radioulnar dissociation is well studied, acute reconstruction of the membrane is infrequently documented and surgical techniques vary. There are only five documented cases of acute IOM reconstruction for Essex Lopresti injuries (ELIs). This is the first described case using a mini suture-button construct in conjunction with a radial head replacement and distal radioulnar joint (DRUJ) pinning, while also providing long-term radiographic and functional follow-up of 2 years.

Case Report

We present a case of a 40-year-old male who sustained an Essex Lopresti fracture that was acutely recognized and surgically managed with a radial head replacement, DRUJ pinning, and acute reconstruction of the IOM with a Mini TightRope suture button construct. We also provide a post-operative rehabilitation protocol with early range of motion and pin removal. At our final 2-year postoperative follow-up, the patient demonstrated excellent functional outcomes.

Conclusion

This case illustrates that a CMC Mini TightRope can be used for acute reconstruction of the IOM in the setting of ELIs which allows for early range of motion and DRUJ pin removal due to the maintenance of longitudinal radioulnar reduction.

An Unusual Terrible Triad Variant Associated with an Essex-Lopresti Injury

Essex-Lopresti injuries and terrible triad injuries of the elbow are rare injuries that typically result from high-energy trauma such as falling from a height or a motor vehicle collision. However, the combination of an Essex-Lopresti injury and terrible triad injury is unique and poses a significant challenge for treatment as these injuries are independently associated with poor functional outcomes if they are not acutely diagnosed. We describe a case of a 19-year-old who presented with an unusual variant of a terrible triad injury associated with an Essex-Lopresti injury. The patient had a distal radioulnar joint (DRUJ) and elbow dislocation, a radial head and coronoid process fracture, and a distal radius fracture. Almost a reverse Essex-Lopresti, this injury was successfully managed with open reduction and repair of the distal radius, radial head, and damaged ligaments in the elbow, along with an internal joint stabilizer (IJS).

Fracture-dislocations of the forearm joint: a systematic review of the literature and a comprehensive locker-based classification system

BACKGROUND

Monteggia, Galeazzi, and Essex-Lopresti injuries are the most common types of fracture-dislocation of the forearm. Uncommon variants and rare traumatic patterns of forearm fracture-dislocations have sometimes been reported in literature. In this study we systematically review the literature to identify and classify all cases of forearm joint injury pattern according to the forearm joint and three-locker concepts.

METHODS

A comprehensive search of the PubMed database was performed based on major pathological conditions involving fracture-dislocation of the forearm. Essex-Lopresti injury, Monteggia and Galeazzi fracture-dislocations, and proximal and/or distal radioulnar joint dislocations were sought. After article retrieval, the types of forearm lesion were classified using the following numerical algorithm: proximal forearm joint 1 [including proximal radioulnar joint (PRUJ) dislocation with or without radial head fractures], middle radioulnar joint 2, if concomitant radial fracture R, if concomitant interosseous membrane rupture I, if concomitant ulnar fracture U, and distal radioulnar joint 3 [including distal radioulnar joint (DRUJ) dislocation with or without distal radial fractures].

RESULTS

Eighty hundred eighty-four articles were identified through PubMed, and after bibliographic research, duplication removal, and study screening, 462 articles were selected. According to exclusion criteria, 44 full-text articles describing atypical forearm fracture-dislocation were included. Three historical reviews were added separately to the process. We detected rare patterns of two-locker injuries, sometimes referred to using improper terms of variant or equivalent types of Monteggia and Galeazzi injuries. Furthermore, we identified a group of three-locker injuries, other than Essex-Lopresti, associated with ulnar and/or radial shaft fracture causing longitudinal instability. In addition to fracture-dislocations commonly referred to using historical eponyms (Monteggia, Galeazzi, and Essex-Lopresti), our classification system, to the best of the authors' knowledge, allowed us to include all types of dislocation and fracture-dislocation of the forearm joint reported in literature. According to this classification, and similarly to that of the elbow, we could distinguish between simple dislocations and complex dislocations (fracture-dislocations) of the forearm joint.

CONCLUSIONS

All injury patterns may be previously identified using an alphanumeric code. This might avoid confusion in forearm fracture-dislocations nomenclature and help surgeons with detection of lesions, guiding surgical treatment.

The serious full-length forearm injury - a case report and literature review

Background

Among upper limb injuries, carpal bone fractures and dislocation, Essex-Lopresti injury, and the terrible triad injury of the elbow are serious and relatively rare injuries. These injuries require surgical intervention. The surgical method is difficult, and the treatment effect is poor. These injuries have not been described in the same limb in the literature.

Case presentation

A 21-year-old male patient fell from a height in our institution and sustained multiple injuries, including carpal bone fracture-dislocation, Essex-Lopresti injury, and the terrible triad injury of the elbow of his right upper limb. After 2 surgeries and rehabilitation, he returned to work. We reviewed available reviews and related literature on serious upper-limb damage.

Conclusions

Full-length forearm injury is very rarely encountered, and the management of such fractures is difficult. Radial head replacement with a metal prosthesis, reconstructed the IOM with Tightrope, and fixed the DRUJ with a K-wire pin is appropriate treatment.

The Serially-Operated Essex-Lopresti Injury: Long-Term Outcomes in a Retrospective Cohort

Objective  The main aim of this article is to report 10-year outcomes after Essex-Lopresti injury (ELI). Study Design  Retrospective case series. Two level I trauma centers and one associated community hospital from 2003 to 2016. Patients  Sixteen patients who sustained an ELI and were treated at one of our three regional hospitals. Intervention  Initially, 4 patients (25%) were treated nonoperatively by immobilization and 12 patients (75%) were treated operatively. Proximal surgery included radial head open reduction and internal fixation (ORIF), radial head arthroplasty, radial head excision and forearm ORIF, and wound debridement. Ten patients (63%) were acutely identified with longitudinal forearm instability. Of these, four patients had the distal radioulnar joint pinned. In the other six patients, the forearm was immobilized. Overall, 16 patients underwent a total of 32 revision surgeries. Main Outcome Measure  Performance of Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE) Physical score, Numeric Rating Scale (NRS) score for pain-severity, and NRS score for satisfaction of overall outcome. Results  Follow-up for outcome evaluation was available for 10 patients, at a median of 10 (interquartile range [IQR]: 8.0-12) years after date of injury. The median PROMIS UE Physical score was 36 (IQR: 33-38). Median NRS score for pain-severity on average was 5 (IQR: 0-6). The median NRS score for satisfaction of overall outcome was 7 (IQR: 5-8). Conclusion  Patients who sustain an ELI generally have substantial deficits of upper extremity function as measured by PROMIS UE. Early radial head arthroplasty may be beneficial, but further study in a larger cohort is needed. Outcomes of nonoperative treatment and operative treatment were similar and suggest that current surgical treatments are incomplete.

Chronic Essex-Lopresti injury: a systematic review of current treatment options

INTRODUCTION

Essex-Lopresti lesion (ELL) is a severe injury. Most of ELL is recognized in chronic phase representing a therapeutic challenge for orthopaedic surgeons. The aim of this systematic review is to highlight and criticize current concepts in the surgical treatment.

MATERIALS AND METHODS

The search was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guideline. A comprehensive research of Pubmed database was made using the following Mesh term: ((Essex-Lopresti injury) OR (Essex Lopresti) OR (distal radio ulnar dissociation) OR (distal radio ulnar dislocation) OR (longitudinal forearm instability)). Quality assessment of each article was performed according to Coleman score by two authors.

RESULTS

Eight full articles were included to the systematic review. Surgical treatment was differentiated in five categories according to the most common procedure reported in clinical series. The mean Coleman Score was 51.13 ± 9.76.

DISCUSSION

Case series reported in the literature include a limited number of patients with chronic ELL. Currently, salvage procedure devoted to treat a wrong diagnosis and an incorrect treatment is used. Radial head replacement together with ulnar shortening osteotomy and interosseous membrane reconstruction are the most common treatments of choice, but at present, there is not yet a shared scheme of management for patients with chronic ELL.

CONCLUSIONS

According to current literature, a case-by-case treatment must always be considered. Further investigations, with higher level of evidence, quality of study design, and number of patients, are needed to better assess clinical results and complication of each technique.

Essex-Lopresti injuries: an update

Reconstruction of the central band of the interosseous membrane is an emerging procedure implemented in the treatment of longitudinal radioulnar dissociation (LRUD), usually in its chronic setting, after Essex-Lopresti injuries of the forearm.

There are no sufficient clinical data to support reconstruction of the central band of the interosseous membrane in acute LRUD injuries.

Clinical and cadaveric studies comparing autografts (palmaris longus, flexor carpi radialis and bone-patellar-bone), allografts (Achilles tendon) and synthetic ligaments have not shown superiority of one technique versus another; however, they have shown special concerns with respect to the use of synthetic grafts.

Latrogenic fracture, decrease of rotational range of movement, iatrogenic nerve injury (superficial radial and median nerve), donor site morbidity with autografts and recurrent instability are the complications reported in literature after interosseous membrane reconstruction.

An uncommon variant of the Essex-Lopresti injury

The Essex-Lopresti injury is an extremely rare condition combining radial head or neck fracture, distal radio-ulnar joint dislocation and rupture of the interosseous membrane. However, there are rare or unusual varieties or associated injuries. We report a case of a 46-year-old woman with a posterior dislocation of the radio-humeral joint, a radial shaft fracture, and a distal radio-ulnar joint dislocation. She underwent open reduction and internal fixation of the radial shaft fracture followed by an immobilization by a long elbow splint in supination for 6 weeks. At 18 months of follow-up, she was asymptomatic and she had a full range of elbow and wrist motion and had resumed thoroughly her previous job. The Essex-Lopresti injury results from a complex injury to the forearm axis with resultant longitudinal instability, which can be challenging to treat. There are some variations that can lead to a missed diagnosis resulting in persistent pain and instability of the wrist. The best outcomes are reached with early diagnosis and prompt management.
