Arthroscopic Management of a Coracoid Fracture Associated With Acromioclavicular Dislocation: Technical Note

Acromioclavicular dislocation associated with fracture of the coracoid process: a series of cases and review of the literature

PURPOSE

Complete acromioclavicular (AC) dislocation associated with fracture of the coracoid process (CP) is uncommon. The strong coracoclavicular ligaments, instead of rupture, may avulse the CP near its base, and with disruption of the AC joint may allow complete dislocation of the clavicle. We report ten cases, one of the largest series in literature, and reviewed the findings and treatment previous reported cases, to allow potential readers to establish the most appropriate treatment.

METHODS

We have prospectively collected those cases in which we had identified an association of an AC dislocation with a fracture of the CP, as well as retrospectively reviewed the records that were coded as AC dislocations and CP fracture looking for this association in the senior author institutions. A literature search was completed on PubMed, Web of Science and Scholar Google, using a sensitive search strategy.

RESULTS

We have collected a total of ten patients with the association of a CP fracture to an AC dislocation in a period of twenty-five years. A review of the cases reported in literature shows a great variability in treatment methods from conservative to more surgically in recent years.

CONCLUSIONS

When an AC dislocation is identified by clinical examination and X-rays, one should be aware of a possible fracture of the CP. It is possible this association to be more frequent than shown in literature because of the CP fracture can easily be missed out or mistaken with an unfussed epiphysis in routine anteroposterior radiography. Multiple approaches have been opted for by surgeons to deal with this combined injury and are the basis of this review.

Arthroscopic reduction and hollow screw internal fixation for Eyres Type IIIA scapular coracoid fracture: a case report

BACKGROUND

A coracoid process fracture combined with an acromioclavicular (AC) joint dislocation is an uncommon injury that typically causes significant pain and limits shoulder movement. Open reduction and internal fixation have been the traditional treatment approach. However, arthroscopic techniques are emerging as a promising alternative for managing these injuries.

CASE REPRESENTATION

A 35-year-old woman presented with right shoulder pain following an accidental fall. Imaging studies revealed a coracoid process fracture along with an AC joint dislocation. The fracture was classified as an Eyres Type IIIA, which warranted surgical intervention. Our team performed arthroscopic coracoid fracture reduction and internal fixation surgery, as well as AC joint dislocation repair using Kirschner wires. Six months after surgery, the patient demonstrated a satisfactory functional outcome with complete bone healing.

CONCLUSION

This case report highlights the potential of arthroscopic reduction and fixation as a novel treatment option for fractures of the coracoid base.

The X-Mas Box Osteosuture: A New Technique for Coracoid Process Fracture

A fracture of the tip of the coracoid is a rare but challenging fracture. A surgical indication is required in case of a displaced fracture. Screws and suture anchors often do not offer a reliable fixation in the case of very small fragments. We describe our hardwareless technique that consists of an osteosuture with a 90-degree suture threads configuration that we called the x-mas box technique. This procedure is cost-effective and it provides stable fixation and low complications rate.

Surgical management of multiple superior shoulder suspensory complex disruptions involving at least a coracoid fracture and an acromioclavicular dislocation: A report of five cases

A combination of coracoid fracture and acromioclavicular dislocation is rare. Detecting further pathologies that could cause multiple superior shoulder suspensory complex disruptions is mandatory. Literature regarding these injuries and their management is lacking. We report our diagnostic and surgical strategies, and the postoperative outcomes of superior shoulder suspensory complex disruptions. We present five cases, treated from 2011 to 2016, who had >2 disruptions of the superior shoulder suspensory complex, involving at least a coracoid fracture and an acromioclavicular joint dislocation. Surgical reconstruction was performed in all cases. The patients were postoperatively followed up for a year. There were no intraoperative or postoperative complications, and bone union was achieved in all fractures. Furthermore, all patients returned to their pre-surgery activity level and jobs. Thus, we could demonstrate that in multiple superior shoulder suspensory complex disruptions involving a coracoid fracture and an acromioclavicular joint dislocation, surgical treatment leads to a good functional outcome.

Arthroscopic Internal Fixation of Coracoid Fractures: Surgical Technique Guide

Fractures of the coracoid process are uncommon injuries and are usually the result of high-energy trauma or avulsion-type injuries. Typically coracoid fractures treated with nonoperative management have yielded good results. Operative treatment of coracoid fractures is reserved for a subset of clinical situations, including fracture nonunion. We detail our technique for arthroscopic debridement of a Type II coracoid fracture nonunion, as well as the use of arthroscopic-assisted percutaneous fixation for a Type II coracoid fracture.
