Galeazzi Fracture-Dislocation Rehabilitation: Radial Shaft Fixation and DRUJ Recovery

A Galeazzi fracture-dislocation is an unstable fracture of the middle to distal third of the radial shaft accompanied by dislocation or subluxation of the distal radioulnar joint (DRUJ). First described by Riccardo Galeazzi, this injury represents a classic fracture of necessity in adults: non-operative casting leads to high rates of non-union, radial shortening, and chronic DRUJ instability. The standard treatment is anatomical open reduction and internal fixation (ORIF) of the radius using a 3.5mm dynamic compression or locking plate, followed by clinical assessment of DRUJ stability. If the DRUJ is stable post-fixation, early protected motion is initiated; if unstable, the joint is pinned with transfixation Kirschner wires or immobilised in supination for 4 to 6 weeks. Physiotherapy must restore forearm pronation and supination while strictly shielding the triangular fibrocartilage complex (TFCC) from rotational shear.

Domestic and Cultural Indian Realities

In an Indian domestic setting, forearm pronation and supination are heavily recruited during cooking and cleaning. Opening tightly sealed glass pickle jars (martaban), twisting wet sarees to wring out excess water, and stirring thick lentils (dal) with a wooden churner (madhani) produce intense rotational torque across the healing DRUJ; these tasks must be suspended for 10 to 12 weeks. Personal ablutions using a handheld water vessel (lota) require pronation; patients should practice smooth forearm rotation with empty vessels before handling full weights. Lifting heavy brass cooking pots (patilas) by their rims places severe bending strain across the radial plate and must be avoided. Commuting on two-wheelers involves twisting the throttle and absorbing handlebar vibration, which is prohibited until radiographic union and joint stability are verified.

Clinical Biomechanics and Anatomical Healing

The radius and ulna articulate at the proximal and distal radioulnar joints, connected along their lengths by the interosseous membrane (IOM). The radius rotates around the relatively fixed ulna during pronation and supination. Fracture of the distal radial shaft disrupts the mechanical balance: the brachioradialis pulls the distal fragment into radial shortening and flexion, while the pronator quadratus rotates it into pronation. Rigid compression plate fixation restores radial length, which often spontaneously reduces the DRUJ. When the DRUJ is unstable, immobilisation in full supination tightens the intact volar radioulnar ligament and stabilizes the ulnar head in the sigmoid notch. Introducing aggressive pronation prematurely places tensile strain across the healing dorsal radioulnar ligament and TFCC.

Validated Special Tests and Differential Diagnosis

Clinical evaluation incorporates the Piano Key Test (pressing down on the ulnar head like a piano key to detect dorsal subluxation and instability). DRUJ ballottement assesses anteroposterior translation in full supination, neutral, and full pronation. Palpation checks for tenderness in the ulnar fovea and TFCC region. Radiographic assessment monitors ulnar variance, widening of the DRUJ space greater than 2mm, and true lateral views to confirm anatomical reduction.

Stage-by-Stage Functional Recovery Protocol

Phase 1 (Weeks 0 to 4 post-op) immobilises the forearm in an above-elbow or sugar-tong splint held in 30 degrees supination if the DRUJ was unstable, while allowing full active finger and thumb motion. Phase 2 (Weeks 4 to 6) removes the splint for supervised active-assisted forearm supination and pronation out of a protective wrist brace, keeping movements within a comfortable 45-degree arc. Phase 3 (Weeks 6 to 12) initiates active wrist flexion-extension, progressive terminal supination stretches, grip strengthening with putty, and light domestic functional tasks once radial union is verified.

Red Flags and Urgent Surgical Indicators

Seek immediate orthopaedic assessment if you notice persistent dorsal prominence of the ulnar head accompanied by a painful clicking sensation during forearm rotation, indicating recurrent DRUJ subluxation. Sudden loss of active thumb extension or numbness on the back of the hand indicates posterior interosseous or radial nerve irritation. Spreading surgical wound redness, warmth, or drainage requires emergency evaluation for deep infection.
