Painful left wrist in a rt handed doctor

 

From the above  xrays  the patient has  a grade 3A Litchman lunatomalacia. 

AP shows a flexed scaphoid ( ring sign) with the carpal ratio altered suggesting lunate foreshortening. 

Radial styloid appears sharp - radial styloid  OA. 

clenched fist AP ( Why)does not show a flexed scaphoid.( cannot explain). is it a correctable scaphoid flexion

Definite ulnar minus

 What would you do?

1. joint levelling procedure ie; radail shortening

2. radial styloidectomy and Scapholunate fusion to unload the lunate with or without lunate excision

3. STT fusion

4. revascularisation  with interacarpal vessel

 my suggestion would be to scope to see if radioscaphoid (styloid OA is present) if present my choice would be no 2. if not 1.

 Any valid advise is welcome for the friend who asked for my opinion

Dislocated bipolar in an octegenarian household ambulator

The decision to do a bipolar is probably correct. the postoperative dislocation and repeated instabilty was surprising. May be a touch of decrease offset added to the instability. If these were a tripolar cup one could imagine an impingement between the neck and the large polyhead could contribute to instability.

intraop the patient had global instabilty due to possible  wrong stem versiosn and soft tissue laxity. we revised the stem with a cememt on cement smaller stem causing smaller offset and still having laxity. so intraop we decided to go for a constrained liner as she was low demand.  

The  final post op xrays with a the +3 head and constrained liner stabilised the hip. The cup is a touch too medial which could have been avoided.  the other option would have been a tripolar cup which could dislocate too due to impingement. The constrined liner could dissociate at the stem head junction if tested as well as wear more quickly

Oops! post acl recon

The patient feels that his knee is not right. He has a 3 degree ffd, full flexion

Femoral component loosening in a ha coated stem in one year

The questions asked were whether revise only the stem and secondly uncemented or cemented revision

My opinion is as follows

The femoral stem has major osteolysis,new bone formation, short duration of implantation and had problems during primary as seen by the circumferential ss wires. It is infected unless proved otherwise. One should aspirated, le test, and intraop frozen section. If you got a decent bug preop one could consider a one stage revision, otherwise be safe and do a 2 stage revision. My choice of stem will be srom and would revise both cup and stem if infected and would go for stem only if the lab is trusted and negative. You could use any modular or mono lock distal loading stem too.

Patella in femur

This xray shown to me by ny colleague is again a pattern I have never seen before. the quads was torn and the distally rotated patella was foung inside the intercondylar fractured femur.

Is this divergent hip dislocation

This radiograph was shared with me  by a colleague. Rt anterior dislocation and Lt posterior fracture dislocation in an RTA.  I have never seen this kind of an  injury before. Apparently he was thrown  off a  moving vehicle and succumbed to his

injuries before orthopaedic intervention..  The direction and magnitude of force  and position of limb at the point of impact determines the injury. The dash board injury and the boat injury combined as described historically

4 yr old painful bipolar arthroplasty in a financially challenged patient referred for opinion

Problems. 

Need a lateral X-ray of the distal stem to see the curvature as well quantify the erosion

I Do not have the patients age 

Financially  challenged patient

Loose stem and possibly cement mantle

Distal long cement mantle

 Medial cortical erosion at the distal end of site

?. Acetabular superior erosion

Hopefully no infection- to be ruled out by preop markers, LE  test and intraop frozen sections and cultures

 A THR is the only option. The  cost of the stem may be the compromise.  I would not use a cemented stem unless you can roughen the smooth endosteal surface abraded by the cyclical stem movement with a broach or burr for cement macro lock (difficult) or if one is good at impaction grafting and a cemented stem ( demanding in technique and patience).

Solutions

 Easy explant with proximal cement mantle and insert a tight fitting HA coated stem like corail after broaching complete removal of proximal cement mantle only and the stem should stop short at least 2 cm above the medial cortical defect - the problem of a peri prosthetic fracture  is real. 

Will a lateral by passing plate to protect the erosion with proximal wires and distal screws help in the compromise. One needd to wait and see. Would local bisphonates  or osteblasts help?

 There used to be a short grit blasted cone  stem by Wagner   With which I had revised in 2002. Iunderstand that zimmer takeover  of Sulzer orthopaedics  killed it.

 Ideally you need a long proximal loading distal fitting stem if the distal cement mantle can be removed  without an eto.  If not an ETO, take the distal cement mantle  and one should get 6 mm of distal scratch fit with a  poor coat stem like solution or even echelon. Template first please

supracondylar nonunion in 62 year old RA patient

This case was  refered for opinion by a colleague from india. Any advise is welcome.

 

My suggestion would be to go for cemented Rotating hinge with distal femoral reaplacement if the nonunion is confirmed intraop. In case there is evidence of  significant stable union I would consider a stemmed,sleeved varus valgus contrained knee aiming for 10 to 15 year survival

current facts on acl reconstruction

single or double bundle reconstruction.

its been clear that double bundle although more anatomic does not give any added advantage as far as results are concerned. It has made us understand the kinematics better and changed the way we do single bundle. The  tibial tunnel being slightly anterior and  femoral tunnel being more horizontal at 930 or 230 position through a medial transportal approach helped as control pivot shift better but not lachman.After all its is pivot shift which damages the knee. Few  surgeon decide on single or double bundle depending on the sixe of the foot pring . If femoral footprint is larger than 18 mm or tibial more than 12 mm a double bundle if prefered.

Bracing or no bracing
at least two recent papers are founfd no difference whether of not bracing postoperative was used. So may be execpt for the non compliant patient. bracing can be left out

Hamstring or patellar tendon.
Recent 15 year prospective  studies have proven tht there are no differences in long term results. May be slightly more anterior knee pain more so kneeling pain with patellar tendon grafts..

OA after acl reconstruction
 The incidence of early osteoarthritis post acl reconstruction is dependant of the meniscal and articular cartilage status than anything else. Many studies do not find deference in osteoarthritis incidence after acl reconstruction but qualify menisectomy and as a bad predictore for OA.

Symptom modifying effect of chondroitin sulfate

　The STOPP study(osteoarthritis progression prevention), a 2 year prospective study have demonstrated definite SYSADOA symptom modifying effect of chondroitin sulfate 800mg/day and structure modifying effect to a lesser degree SMOAD.  SO, may be we can continue with chondroitin sulfate  as a symptom modifying drug with no major side effects. its a good idea to check and monitor  blood glucose and  serum cholestrol during the first few months as there are some rare reports. May be a biochemical mri - sodium mri in a 7 T machine could enligthen us further

Procedure specific competence

Competence of doctor for specific procedure should be assessed/certified before new procedures are attempted. Our patients are not Guinea pigs to be practised on. Where has the Hippocrates oath we all took gone? Are values diluted by politics, religion and greed or just a reflection of the society we live in. I do believe patients have every right to see clinical audits from the department concerned before being subjected to  procedures.

 

Most Hospitals pay lip service to quality control. How on earth can a doctor see 100 patients a day? Are patients fools to believe that spending 5 mins with a patient is enough to  plan his complex management?. Of course per unit costs will go up. Isn't qualty worth the costs. When will our patients understand the con some of our "god like doctors " do in the name of medicine?. The PR will put many a  film star to shame. Marketing self, hospitals and products is the mantra of  the day. Protected time for physicians  for audits are necessary. May God help our profession,patients and world at large.

Patella tilt post TKA

My colleague Dr gnanavel has just come out with a paper  that a patellar tilt of more than 10 degrees might be associated with poor out come in TKA when patella specific scores are used to predict the outcome. He suggested that it would  be advisable  to use patellar specific scores in all future studies investigating the ever controversial patella in TKA. So consider merchants or skyline view and melbourne scores to asses anterior knee pain which is ever present if you ask for it in 10 to 30 percent of individuals.

fracture neck 6 yrs post resurfacing arthroplasty

              I was asked what to do next.

It appears the the femoral  metaphysis is abnormal. Is it an old infection or something else? The safest option would be a complete revision to a ceramic on ceramic bearing or ceramic on vit e poly in view of the bad press with metal on metal. The comonest cause of failure at medium term as above is if the primary indication was in AVN. One could consider one of the short stems in the market today like metaphyseal engaging short stems from metha hip from aesculap, silent hip from depuy, taperloc,balance microplasty to avoid the canal compromised deformed metaphysis.But remember these microhips have at best  year results in expert hands.

one needs to be careful to avoid loosing more acetabular bone while explanting the cup. May be the zimmer explant system would help.
