Radiohumeral Joint Dysfunction: Lateral and Posterior Glide Joint Mobilization Therapy
In short
Articular dysfunction of the radiocapitellar joint mimics and perpetuates lateral epicondylalgia. Discover how posterior and lateral glides restore joint mobility.
In this guide (4 sections)
While clinical attention in lateral elbow pain predominantly focuses on contractile tendon pathology, intra-articular dysfunction of the radiohumeral (radiocapitellar) joint represents an underappreciated primary cause and perpetuating factor. The radial head articulates with the hemispherical capitellum of the humerus, facilitating both elbow flexion-extension and forearm pronation-supination. Minor alterations in radiocapitellar arthrokinematics, capsular restrictions, or subtle anterior subluxation of the radial head can generate focal lateral joint pain that perfectly mimics extensor carpi radialis brevis tendinopathy while resisting isolated soft tissue interventions.
Impact Loading from Falls and Indian Household Floor Work
In Indian daily environments, minor traumatic falls onto an outstretched hand (FOOSH) are common occurrences on wet tiled floors, uneven pavements, or during monsoon commutes. While these minor falls frequently do not result in overt bony fractures, the abrupt axial compression drives the radial head forcibly against the capitellum, causing microscopic articular cartilage contusion and posterior or anterior radial head malpositioning. Furthermore, daily domestic activities involving heavy pushing against rigid surfaces, such as moving heavy furniture or vigorous laundry scrubbing on stone slabs, maintain persistent joint jamming.
Radiocapitellar Arthrokinematics, Meniscoid Inclusions, and Chondral Shear
During normal elbow extension, the concave fovea of the radial head slides posteriorly across the convex capitellum; during flexion, it slides anteriorly. Furthermore, a fibrocartilaginous posterolateral synovial fold or meniscoid structure resides within the radiocapitellar joint. Following repetitive compressive trauma or persistent muscle spasm, this synovial fringe can become hypertrophied and pinched between the radial head and capitellum, generating sharp lateral pain during terminal extension. Additionally, restricted posterior gliding of the radial head forces compensatory shear stress onto the overlying deep fibers of the ECRB tendon footprint, predisposing to chronic tendinopathy.
Maitland Passive Mobilization Grades, Posterior Glides, and Capsular Stretches
Physical examination assesses passive accessory motion of the radial head, comparing anteroposterior and posteroanterior glide excursion and end-feel between limbs. Physiotherapy management utilizes Maitland passive oscillatory mobilizations (Grades III and IV) to restore restricted posterior glide. The clinician stabilizes the distal humerus and applies a direct, firm posterior glide to the anterior margin of the radial head while moving the elbow into terminal extension. Mobilization is paired with radiocapitellar distraction techniques, soft tissue release of the supinator and pronator quadratus, and active functional movement re-education.
Active Assisted Radial Head Posterior Glide and Terminal Extension Drill
Objective: Restore posterior translation of the radial head and normalize terminal elbow extension mobility
- 1Sit beside a table, resting the back of your affected arm and elbow flat on a folded towel with your palm facing upward.
- 2Use the thumb pad of your opposite hand to locate the bony radial head on the outer front of your elbow joint line.
- 3Apply a gentle, firm, sustained downward (posterior) pressure against the front of the radial head.
- 4While maintaining this steady posterior thumb pressure, slowly and gently straighten your elbow completely flat against the table.
- 5Hold the end-range extension for 3 to 5 seconds, slowly bend the elbow slightly, and repeat.
| Physical Examination Domain | ECRB Contractile Tendinopathy | Radiohumeral (Radiocapitellar) Dysfunction |
|---|---|---|
| Focal Tenderness Location | Pinpoint tenderness directly on the lateral epicondyle or 1 cm distal in tendon body | Tenderness precisely on the radiocapitellar joint line and rim of the radial head |
| Passive Terminal Joint Mobility | Elbow flexion and extension are completely full and pain-free when wrist is neutral | Terminal elbow extension is blocked or provokes sharp lateral joint pinch and crepitus |
| Accessory Motion Palpation | Posterior and anterior glides of radial head exhibit normal excursion and springy end-feel | Restricted posterior glide of the radial head with firm, capsular, or painful end-feel |
| Response to Resisted Extension | Strongly painful with wrist extension; minimal change with joint distraction | Variable pain with resisted extension; pain significantly reduces when joint is distracted |
If passive elbow extension reveals true mechanical locking, clunking, or an unyielding hard bony block, obtain plain radiographs and MRI to rule out osteochondritis dissecans of the capitellum or intra-articular loose bodies before performing forceful joint mobilizations.
Frequently Asked Questions
How can I tell if my lateral elbow pain is a joint problem or a tendon problem?
Tendon problems primarily hurt when you actively use your muscles, such as gripping or lifting objects with your wrist. Joint problems, in contrast, typically cause stiffness, clicking, or pinching when you straighten or bend your elbow completely, even when your hand and wrist are totally relaxed.
