What an MDT discussion is meant to settle
Hip avascular necrosis, also called osteonecrosis of the femoral head, is a condition where the blood supply to part of the femoral head is disrupted and bone can collapse over time. The decision that matters most to an overseas patient is not simply whether surgery is possible, but which stage the disease has reached and whether the hip can still be preserved or whether the joint surface is already too damaged. A multidisciplinary discussion brings together the specialties whose opinions change that decision, typically an orthopedic hip surgeon, a musculoskeletal radiologist and sometimes a rheumatologist or a physician managing the underlying cause.
The purpose of that discussion is to produce a defensible answer to a small number of questions, not a general opinion about the disease. If those questions are not answered, the patient travels or commits to a plan without knowing what is actually being treated. The sections below set out the specific questions to put in writing, why each one changes the decision, and how to phrase them so a hospital can respond usefully.
One boundary applies throughout. ChinaSpecialistCare can arrange a multidisciplinary review for a complex or cross-specialty case, and the scope and fee are agreed first. No hospital is required to run its cases through that format, and the treating team alone decides whether a given patient is suitable for any procedure.
Question one: what stage is the hip at, and on what evidence
Staging is the foundation of every later decision. Avascular necrosis of the femoral head is commonly classified by how much of the head is involved and whether the surface has already collapsed. A hip that is still before collapse is discussed differently from one where the articular surface has failed. If the stage is uncertain, the discussion cannot reliably compare preservation with replacement.
Ask the reviewing team to state the stage explicitly, to name the classification system they used, and to say which images support that stage. A plain X-ray can show established collapse, while MRI is generally needed to assess the extent of involvement earlier in the disease. The discussion should confirm whether the available imaging is recent enough and complete enough for the team to commit to a stage, or whether something is missing.
This matters because a records-based review can only work from what has been supplied. If the MRI is old, incomplete or only reported rather than available as images, the team should say so rather than estimate. The practical action is to ask, in writing: which stage do you assign, which classification, and which specific images did you review? A clear answer here prevents the rest of the discussion from resting on an assumption.
Question two: is joint preservation still realistic
Joint preservation covers procedures intended to keep the patient's own hip rather than replace it. Whether that is realistic depends heavily on stage, on how much of the head is involved, and on the patient's age and activity level. The discussion should state plainly whether preservation is a genuine option, a marginal one, or no longer appropriate, and it should explain the reasoning rather than simply naming a procedure.
Ask the team to address the alternatives side by side. If preservation is proposed, what is it intended to achieve, what are its limitations, and what would prompt a later conversion to replacement? If replacement is proposed, why is preservation not considered suitable in this case? A discussion that only endorses one route without explaining why the other was set aside is less useful to a patient deciding whether to travel.
The patient's own priorities belong in this question. Age, work, sport, willingness to accept a further operation and the importance of avoiding a major joint replacement all influence which route is reasonable. The reviewing clinicians should be asked how those factors were weighed. This is a question for the treating team, not something a coordination service can decide.
Question three: what previous hip procedures and records change the picture
Previous surgery on the same hip materially changes both the assessment and the options. Prior procedures, implants, bone grafting or fixation can alter the anatomy and affect what a later operation can achieve. The discussion should state which previous procedures the team has reviewed and how each one affects the current recommendation.
The same applies to the underlying cause. Avascular necrosis is associated with several conditions and exposures, and the team managing the hip needs to know what has already been investigated. Ask whether the review has identified a cause that needs separate management, and whether any current medication or condition affects the timing or choice of procedure. Do not change any medication on the basis of a remote review; that belongs to the treating clinician who knows the patient.
A practical records question follows from this. Ask the team to list which documents they actually reviewed and which are missing. If operative notes, implant details or prior imaging are absent, the team should say how that limits the opinion. Supplying a complete operative history is one of the most useful things a patient can do before any discussion.
Question four: what the discussion cannot answer without seeing the patient
A records-based multidisciplinary discussion has real limits, and a good one states them. It can interpret imaging, compare options and identify what is missing. It cannot examine the hip, test the range of movement, assess gait in person or confirm fitness for anesthesia. Those require the patient to be present and are part of what the treating hospital decides.
Ask the team to separate what it can conclude from records and what it must confirm in person. This distinction protects the patient from treating a remote opinion as final clearance. A remote review does not establish hospital acceptance, a confirmed surgical plan or a guaranteed outcome, and it should not be presented as doing so.
If the discussion recommends a procedure, ask what further assessment would be needed before that recommendation becomes a plan. The answer usually includes a physical examination, possibly updated imaging, and pre-operative checks. Knowing this in advance helps a patient understand which parts of the process are provisional and which are settled.
How to request the discussion and what to send
The most useful request is short and specific. State that the patient has confirmed or suspected avascular necrosis of the femoral head, that a multidisciplinary opinion is being sought, and list the questions above. Ask the hospital or coordination team to confirm whether that format is available for this case before any fee is agreed. No hospital is obliged to provide it, and the scope should be settled in writing first.
For the records, send a brief summary first rather than a complete archive. A useful starting set includes the most recent hip imaging with the radiology reports, any operative notes from previous hip procedures, a list of current diagnoses and medications, and a short statement of the patient's main question and priorities. Ask which additional documents would help, and send those only when requested. Do not send passport numbers or payment details at this stage.
ChinaSpecialistCare can arrange a multidisciplinary review involving two or three relevant specialties for a complex or cross-specialty case, with the scope and fee agreed beforehand. The team can also help match the case to a suitable specialist and prepare the appointment. Hospital consultation, imaging and treatment fees are paid to the hospital and remain separate from any coordination fee.
A brief next step: send a short summary of the diagnosis, the main question and the available hip records through the enquiry form, email or WhatsApp. An initial enquiry is free and does not commit the patient to a proxy consultation or any procedure. The relevant procedure reference for the surgical side of this decision is total hip replacement, which explains what replacing the damaged ball-and-socket surfaces involves and why suitability is assessed individually.
