Fractures of the coracoid process

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Traumatology

Background:

• Fractures of the coracoid process are uncommon shoulder injuries.
• Classification systems aid in understanding injury patterns and guiding treatment.
• The coracoclavicular ligament's relationship to the fracture is a key anatomical consideration.

Purpose of the Study:

• To classify coracoid process fractures based on their relationship to the coracoclavicular ligament.
• To evaluate treatment outcomes for different fracture types.
• To determine optimal surgical indications for coracoid process fractures.

Main Methods:

• Retrospective review of 67 consecutive patients with coracoid process fractures.
• Classification into Type-I (posterior to coracoclavicular ligament) and Type-II (anterior to ligament).
• Analysis of associated injuries, treatment modalities, and patient outcomes at follow-up.

Main Results:

• 53 Type-I and 11 Type-II fractures were identified.
• Type-I fractures were frequently associated with other shoulder injuries and scapuloclavicular dissociation.
• 87% of followed patients achieved excellent results, irrespective of treatment type (operative vs. conservative) or fracture classification.
• No significant outcome differences between operative and non-operative groups or between Type-I and Type-II fractures.

Conclusions:

• Coracoid process fracture classification based on coracoclavicular ligament proximity is feasible.
• Conservative treatment may be effective for Type-II fractures.
• Operative intervention should be reserved for Type-I fractures with significant scapuloclavicular disruption and associated injuries.
