Elbow Fractures in Adults: Getting the Complexity Right
Adult elbow fractures present some of the most technically demanding decisions in upper limb trauma. The joint's tight tolerances — where a few degrees of malreduction or a millimetre of articular step mean the difference between an excellent and a mediocre outcome — combined with its propensity for stiffness and the complexity of its neurovascular anatomy make these injuries unforgiving of imprecision in either assessment or management.
The elbow joint tolerates anatomical imprecision poorly. The complex three-dimensional geometry of the distal humerus, the tight articular congruity of the radiocapitellar and ulnohumeral joints, and the close proximity of the ulnar, radial, and anterior interosseous nerves to the fracture planes that most commonly occur in this region all create an environment where surgical planning must be precise, surgical execution meticulous, and post-operative rehabilitation carefully calibrated to balance early motion against healing stability.
Distal humerus fractures: the planning imperative
Displaced intra-articular distal humerus fractures in active adults require surgical fixation in the vast majority of cases — the functional demands of the elbow and the joint's intolerance of articular malreduction make non-operative management appropriate only in specific circumstances. Preoperative CT with three-dimensional reconstruction is no longer optional — it is the standard of care for complex distal humerus fractures, providing the anatomical detail that determines implant selection, approach planning, and fixation strategy.
The parallel plating construct — medial and lateral columns stabilised by orthogonal or parallel plate configurations — provides the biomechanical stability that allows early mobilisation, which is the single most important determinant of functional elbow range of motion after distal humerus fixation. Surgery that achieves stable fixation but requires prolonged immobilisation will produce an elbow that is mechanically sound and functionally limited. The surgical plan must include a rehabilitation strategy that begins within days of the operation.
Radial head fractures: the Mason classification in practice
Mason Type I fractures — undisplaced — are managed non-operatively with early mobilisation: the evidence overwhelmingly supports this approach and the outcomes are excellent. Type II — partial articular, displaced — require clinical judgment: isolated radial head fractures without block to forearm rotation in patients willing to accept the small risk of late symptoms can be managed non-operatively; those with mechanical block or in the context of an Essex-Lopresti injury require fixation. Type III — comminuted — require either fixation when technically achievable or radial head arthroplasty; excision alone without addressing the interosseous membrane and DRUJ stability is no longer acceptable practice.
Elbow fractures reward the surgeon who plans meticulously, operates precisely, and mobilises immediately. They punish every deviation from this triad with stiffness, pain, and functional limitation that is very difficult to reverse.
