Pneumothorax, pulmonary contusion, rib and clavicle fractures, brachial plexus and head injury accompany a large share of cases, making the scapula a trauma marker that obliges a systematic search rather than a shoulder X-ray report. Treatment is predominantly non-operative: body and most neck fractures heal well in a sling with early pendular movement. Intra-articular glenoid fractures are the exception, classified by Ideberg, and displaced fragments or glenohumeral instability are internally fixed; the floating shoulder — a glenoid neck fracture with a broken clavicle — is usually stabilised by fixing the clavicle. ## What you must remember - **Rarity and company:** under one per cent of all fractures, typically young men in high-energy crashes; associated injuries are found in most, so the scapular fracture should trigger a chest, spine and neurovascular survey, not a sigh of relief. - **The trauma-marker duty:** look for pneumothorax and haemothorax, pulmonary contusion, rib fractures, clavicle and proximal humerus fractures, subclavian or axillary vessel injury, and brachial plexus damage. - **Regional anatomy:** body fractures are the commonest and almost always treated non-operatively; glenoid neck, glenoid cavity, acromion and coracoid complete the map. - **Ideberg classification of glenoid fractures:** I — anterior glenoid rim; II — transverse fracture through the fossa exiting inferiorly; III — exiting superiorly; IV — exiting through the medial scapular border; V — combinations of II, III and IV; VI — comminuted. - **Operative thresholds:** an intra-articular step of roughly 4 mm or more, glenohumeral instability, or significantly displaced neck and process fractures; glenoid planning demands computed tomography with three-dimensional reconstruction. - **Floating shoulder:** scapular neck fracture plus clavicular fracture interrupting the superior suspensory complex of the shoulder; plating the clavicle frequently restores the whole ring, with scapular fixation added for residual displacement. - **The catastrophic cousin:** scapulothoracic dissociation — lateral scapular displacement with massive soft-tissue disruption, brachial plexus avulsion and vascular injury, a limb- and life-threatening entity with a flail, numb, pulseless arm. ## One fracture, a whole body survey A 30-year-old arrives after a motorcycle crash with right shoulder pain; the chest film obtained for rib evaluation shows a scapular body fracture. The survey runs outward from the marker: air entry and tracheal position for pneumothorax, rib tenderness, a neurological examination for plexus injury, a pulse comparison. Nothing else is broken. The fracture itself becomes almost an anticlimax — a sling, analgesia, pendular exercises within days, and return of shoulder function over six to eight weeks. Contrast the same crash with a force driving the humeral head into the glenoid: computed tomography shows an Ideberg V fracture with a 5 mm step and a subluxed head — the operative minority, treated by open reduction through a posterior approach with screws or a mini-fragment plate, because a step that size under a load-bearing ball breeds early arthritis. Between the two patients lies the entire teaching: most scapulae need a sling and survey; the glenoid that carries the joint needs a CT and, if displaced, a plate. ## Where the marks hide The highest-yield sentence is the trauma-marker principle: asked "a patient has a scapular fracture — what next?", the winning answer is a systematic search for pneumothorax, pulmonary and vascular injury, not a discussion of the shoulder. The second mark hides in Ideberg — examiners rarely need all six types, but naming I (rim), IV (medial exit) and VI (comminuted) shows the map is known. The third is the floating shoulder, asked as a concept — two breaks in the suspensory ring, fix the clavicle and the ring usually holds. Indian practice supplies the cases — helmeted two-wheelers and unguarded construction falls — with scapular fractures under-called on poor portable films; the practical skill is insisting on the survey the fracture predicts. ## Frequently asked questions ### Why is a scapular fracture called a trauma marker? Because breaking a bone shielded by thick muscle demands enormous energy, and most patients harbour associated injuries — pneumothorax, pulmonary contusion, rib, clavicle, vascular or brachial plexus damage — that are more dangerous than the fracture itself. ### Which scapular region is most often fractured and how is it treated? The body, and almost always non-operatively, with a sling, analgesia and early pendular exercises. ### What is the Ideberg classification? A system for glenoid cavity fractures: type I anterior rim, II-IV linear fractures exiting inferiorly, superiorly and medially respectively, V combined, VI comminuted — displacement or instability selects patients for surgery. ### What is a floating shoulder? A scapular neck fracture combined with a clavicle fracture, breaking the superior shoulder suspensory complex in two places; clavicular plating commonly restores stability. ### When is surgery indicated for a glenoid fracture? For an intra-articular step of around 4 mm or more, glenohumeral instability, or significantly displaced fragments — planned on computed tomography.
