Elbow condition
The elbow is held steady by ligaments on both sides, and a fall or forced twist can stretch or tear them. Most sprains settle well. What is worth knowing is that the two sides tell different stories: the inner ligament is the throwing one, while the outer ligament complex is the one injured in falls and dislocations — and the one most often missed, because when it fails the elbow does not simply hurt, it feels untrustworthy. That sensation of the joint being about to give way, particularly pushing up out of a chair, is the clue that matters most.
Tap any that apply to you — this is guidance, not a diagnosis, but it helps separate a simple sprain from an unstable elbow.
Worth examining properly — because the important question is not how much it hurts but whether it is stable. A straightforward sprain settles with protection and early movement. A sense of the elbow giving way, apprehension loading it palm-up, or a clunk you can feel points to the outer ligament complex being incompetent, which is largely a clinical diagnosis and is easily missed if only the imaging is looked at.
If the pain sits on the inner side and comes on with throwing or serving rather than after a fall, that points to the other ligament. The inner ligament takes the strain of throwing and is assessed and treated differently. More: ulnar collateral ligament injuries
Which ligament was injured, and how, decides almost everything that follows:
For a fresh sprain, protect it briefly, then get it moving. A sling or brace for comfort in the first days is reasonable, along with settling the swelling — but the elbow stiffens faster than almost any joint, so prolonged immobilisation costs more than the sprain did. Ask when movement can start and begin it promptly, then build strength in the muscles that support the joint, since they take a good deal of the load that ligaments would otherwise carry. Avoid the positions that provoke apprehension while it settles: pushing up from a chair with the palms turned back, deep press-ups, and heavy loading with the arm part-bent and palm up. What is worth flagging rather than working around is the feeling that the elbow might give way. That is not simply a sprain taking its time; it suggests the outer ligament complex is not doing its job, and it is largely diagnosed by examination rather than by a scan — so being told the imaging looked fine is not the same as being told the elbow is stable.
The right step depends on whether it is sore or unstable — tap the one that fits:
Most fresh sprains do well — the priority is protecting it briefly, then moving it. Settle the swelling, use a sling or brace for comfort in the first days, and start guided movement early because this joint stiffens quickly. A progressive strengthening programme then takes over. An assessment confirms nothing is broken and checks the joint is stable.
That sensation is the one worth investigating properly. Apprehension loading the arm palm-up, or a clunk as the joint shifts and returns, suggests the outer ligament complex is incompetent — a diagnosis made largely on examination, since standard imaging can look unremarkable. Bracing and targeted strengthening help many; persistent instability can be reconstructed.
An elbow that dislocated and has never felt trustworthy deserves a proper look. The ligaments tear whenever the joint comes out, and while many heal well enough, some are left functionally incompetent. That is a treatable problem rather than something to work around, and identifying it is mostly a matter of the right examination.
Treatment turns on one question: is the elbow sore, or is it unstable?
Tap each card to reveal the truth:
Two sets, on opposite sides, and they behave quite differently. On the inner side, the ulnar collateral ligament resists the forces of throwing — it is the one that frays in throwers and overhead athletes. On the outer side sits the lateral ligament complex, which resists the elbow rotating and levering open, and it is the set injured in falls and dislocations. The outer one is the more commonly overlooked of the two, partly because its failure produces a sense of unreliability rather than straightforward pain, and partly because it is easy to attribute that feeling to something else.
That sensation, rather than pain, is the hallmark of ligament insufficiency on the outer side of the elbow. It shows up in a very specific situation: loading the arm with the palm turned up and the elbow partly bent — pushing yourself up out of a chair, coming up from a press-up, or bracing on a table. The joint rotates slightly out of position and then clunks back, producing a moment of apprehension. People often describe it as the elbow feeling untrustworthy rather than sore, and it is worth reporting precisely, because that description is itself the clue.
It can, and this trips people up. Instability on the outer side of the elbow is primarily a clinical diagnosis — made by specific examination tests that reproduce the joint rotating and clunking — and a standard scan can look unremarkable while the ligament is functionally incompetent. A scan is genuinely useful where a fracture is suspected, where a full-thickness tear needs confirming, or where surgery is being planned, but a normal report does not exclude the problem. Being told the imaging was fine while your elbow still feels unreliable is a reason to be examined properly, not reassured.
Repeated injections into the outer elbow can weaken the tissue there, and the lateral ligament complex attaches immediately beneath the tendon that is usually being targeted. That is one recognised route to instability on the outer side of the elbow, alongside falls and dislocations. It is not a reason to avoid an injection where one is genuinely indicated, but it is a good reason not to have them repeatedly for a stubborn tennis elbow, and a good reason to favour a proper loading programme instead — which is in any case the treatment with the better long-term evidence.
The great majority settle without surgery. A short period of protection, then early guided movement, then a progressive strengthening programme for the muscles that support the joint — this joint stiffens quickly, so prolonged immobilisation does more harm than the sprain did. Where the elbow is genuinely unstable, the plan changes: bracing that controls the position, a longer rehabilitation, and for persistent instability that limits daily activity, reconstructing the ligament. The decision turns on whether the elbow is simply sore or actually giving way, which is precisely what the examination sets out to establish.
