Follow-up for the previous post to show the final photos. I harvested from the ipsilateral thigh for the split thickness skin graft. In general, when wounds are 100% granular, they’re ready for skin graft, does not require skin substitutes at that point. This took very well and healed in a month, some of the edges struggled to heal the final bits hence the 2 month healing after STSG.

This case shows a man in his 60s with diabetes, who developed a necrotizing soft tissue infection with bacteremia, needing emergent transmetatarsal amputation with wide debridement of the plantar soft tissues. The infection was tracking superficially along the plantar fascia, so that had to be removed. Makes sense since he did end up culturing staph aureus, which is an aerobic bacteria, likes to stay close to skin. He did have triphasic 3-vessel flow so he did not require vascular surgery. My colleague did a TMA revision to shorten the bones so on the 3rd surgery, I was able to close over the bony stumps and cover the rest of the wound with a scaffold skin substitute (Theragenesis). He was discharged on a PICC line for his endocarditis.

There was a little setback with lateral wound necrosis that needed in office debridement, but he eventually granulated in 3 months. He was compliant about non-weight-bearing restrictions for that time which helped with successful wound healing. I didn’t use a wound vac in this case. Humans have been granulating before the wound vac was patented in 1991 and we can continue to granulate without it. Getting source control is the hard part, once it’s clean enough, it’s remarkable how well patients heal with little effort afterwards.

This post shows a case of a man in his 40s who developed gangrenous wounds due to walking on hot concrete, with history of diabetes and microvascular disease. He developed a dorsal foot wound after 2nd toe amputation that needed a wide debridement with I&D, and delayed wound closure. He eventually was discharged but needed to be admitted again due to pulmonary issues and anasarca, which subsequently lead to the 3rd toe becoming partially gangrenous from the reduced oxygenation. At this point he had a large dorsal wound that was granulating, but plantar foot wounds that were slow to heal. The dorsal foot wound was skin graft ready, but the plantar wounds were not. Also due to his pulmonary issues and widespread edema, I figured it’s best to reduce donor site morbidity and avoid a large split thickness skin graft donor site. Since he needed wound care on the plantar foot wounds for a while anyways, it didn’t give him much benefit to heal the dorsal foot wound rapidly, so I decided a pinch graft would be a good middle option. It’ll help generate separate islands of skin that will start their own center for secondary wound healing, reducing the overall time to heal otherwise albeit not as fast as a STSG would. My post-op protocol for a pinch graft is:

1st week: xeroform gauze kerlix ACE left alone
2nd week: change dressings 1-3x per week with xeroform betadine gauze (depending on size of wound and drainage). Weekly debridements to keep the granular tissue biofilm free. Keep this going until healed.
Same as above for donor site minus the debridement

The pinch grafts are described without fixation, just wrap with a dressing. They do migrate a tiny bit, but they usually take pretty well. Donor site heals quickly too even if you went to subq level in the center bit since it’s a variable thickness harvest. This is a good option for speeding up epithelialization when parts of the foot are not yet ready for STSG and still needs wound care. I harvested mine from the thigh, but if you have scope issues, just harvest from the calf, or even near the wound itself.

See previous post to see how we got to this point.

The donor site where the ABductor muscle belly lies re-granulated that defect in time for STSG in a month. He eventually was able to get the whole thing healed in 4 months from time to presentation to the hospital. He will still need a lot of work to let that TMA stump soft tissue mature to be able to withstand the shear of walking, and will need to be closely monitored, high chance of re-ulceration, but we gave him the a good chance of long-term meaningful ambulation with the severity of infection he had.

Lots of questions about if I used wound vac. I did not use wound vac for this case. Not wrong to use it, but there are so many issues with the wound vac that I decided to cut it out from my practice altogether, I have not applied or ordered one for 2 years and it has not impacted my ability to get good results. There’s even a recent Lancet article talking about how wound vacs do not help with post-surgical secondary wound healing.

For STSG, I use xeroform gauze wrap, I don’t do tie-over bolster dressings anymore, found out a simple wrap works. There’s plastic surgery articles to support that. There’s a Georgetown article that suggest 3:1 mesh ratio has the least complications, I haven’t noticed a big difference so I used 1.5:1 in this case, sometimes 3:1 for larger wounds. There’s another Georgetown article that suggests STSG for plantar foot wounds are a viable option. I think this is true, because so many other factors contribute to longevity of a plantar wound, such as distance between skin and bone (need soft tissue bulk to cover bone for high level ambulators).

Lastly, it’s important if you want to specialize in this, to eventually build a reliable team around you that are like-minded, hard-working, and passionate about limb salvage. Because it’s difficult to do this alone and you can handle only so much. Emergency surgeries never happen at convenient times, and you’re never always available (nor should you be). We have a staggered schedule of availability of limb salvage podiatrists that work together in private practice and we are thriving while helping the community.

This case shows a young man newly diagnosed with diabetes who unfortunately developed a necrotizing great toe infection that spread into the midfoot requiring transmetatarsal amputation and multiple debridement surgeries. Go through the slides to see all the clinical clues I look for. MRI or CT scan will not know whether the pathologic findings are edema or necrosis, and it’s the soft tissue damage that dictates surgical treatment of these acute infection cases.

Luckily this was a strep infection, which likes to stay superficial, so most of the damage was more to skin and soft tissue (albeit widespread) but this is easier to replace than anaerobic infections that like to go deep and cause damage to the muscles which is harder to replace.

He was eventually discharge with a little remaining necrosis still present, which is not recommended for weaker hosts, but this is a young strong host with good flow who doesn’t smoke, so he could handle the debridement and logistics associated with subsequent staged outpatient surgeries. I got him to granulate with weekly debridements, and dressing changes consisting of xeroform, gauze, kerlix, ABDs. Only issue remaining is the plantar flap that needs to be tacked down, and the 1st met bone that was necrotic. Simply cutting it flush to create a guillotine type wound might be fine for lower level ambulators, but for a younger person who needs to walk a lot, this will not do well, it needs bulk. I decided to do a random rotational flap using the granular tissue under the ABductor muscle belly. Granulation tissue is extracellular matrix with a random network of capillaries, basically it’s a vascularized skin substitute, perfect product to use to cover bone and tendons. I got the bone covered using this granulation tissue random rotational flap, tacked down that plantar flap, and continued with the usual weekly debridements and xeroform betadine gauze dressing changes.

This case involves a newly diagnosed diabetic who found out when he had a necrotizing infection to his great toe. It was so severe it ended up requiring a transmetatarsal amputation and a wide debridement, leaving him with a large soft tissue defect. Luckily, it was strep, which tends to like to erode superficial spaces, not deep. I say luckily because it’s easier to replace superficial structures such as skin, harder if it went deep for example into the master knot of Henry, it could erode the deep layers of the plantar foot which leaves us with not much to work with. If you go through the slides I discuss in detail some of the clinical clues I look for. MRI or CT scan can only detect edema, so it won’t know if the muscle edema is myonecrosis or simply inflammation. Same with the subcutaneous fat, MRI can just detect edema, it won’t know if it’s necrotizing, which is a 100% clinical diagnosis. Also this case came back as negative for osteomyelitis on pathology, but it’s a good example of how acute diabetic foot infections are soft tissue dominant that sometimes just so happen to involve bone. It doesn’t matter whether the bone is infected, the soft tissue damage dictates our amputation decision.

He eventually was discharged with still some residual necrosis which isn’t recommended for weaker hosts, but this was a young strong host who could handle the outpatient management. He was seen by me in office weekly for debridements, and through simple xeroform betadine gauze ABD dressing changes several times a week he granulated without the need for a wound vac. The only hard part was the residual necrotic 1st metatarsal that had no viable periosteum to help granulate, plus with the plantar flap sorta loose, he needs an OR debridement, so I was focused on getting the rest of the wound ready for partial closure and 1st metatarsal resection. The problem was that in young patients who need to walk a lot, guillotine style closures don’t do well long-term. That 1st metatarsal stump will need more than just a skin sub, it needs bulk for it to be functional. See my next post to see what happens.

This is the followup to the previous post. Here’s the X-rays of the arthritis after pin placement. Yes it can happen, but I’ll take it over the risk of an unstable graft that won’t help cover the FHL tendon. I think in the future I might try to use a monorail ex-fix instead of a pin.

The case I posted on Nov 7, 2023 is much more dramatic, involving a wound with actually joint capsule necrosis, and I used 3 pins instead of 1 because of his restless leg syndrome. He would otherwise have had no chance of healing that complex wound involving bone and joint. Just scroll down to find that post series!

Here is a repost of a recent Instagram stories, grand rounds style case I presented of a diabetic foot infection in a young man with neuropathy, and even though these cases are technically simple “first year” cases, the thought that goes behind it is not something to be taken lightly. What I find interesting is that this toe could have gone on to amputation and no one would bat an eye, however, I when I try to save it, I get a lot of concerns about my method of putting a pin across the joint to stabilize a graft in the setting of an acute infection. I’ve learned over the years is that the zone of infection is predictable and not something to be feared.

If you look closely to the location of the pin, you will realize that I did not put it in the zone of infection, there was no pus or necrosis involving the bone or the tip of the great toe. Also, the time of pin placement was during the subsequent surgery where I confirmed adequate source control, clean enough to apply a skin sub. I used Dermacell because it has better long term durability and is pliable so it can be shaped into the irregular sized wound.

Another point to bring up about the pin is that we really should scrutinize the cleanliness of the wound prior to scaffold graft application. I see people apply skin subs on wounds that are still infected, yet blame the graft for not working rather than scrutinize the cleanliness of the wound bed. My criteria for source control is absence of necrosis or thrombosis.

For a more dramatic example of why it’s important to immobilize a joint for graft healing, see the case I posted on November 7, 2023.

This is a 60 year old female, history of smoking, hypothyroidism, she slipped on ice, fell, and broke her ankle. She underwent ORIF by a colleague, and had trouble healing both the bone and the skin. She eventually had hardware exposed and was sent to me to help with coverage. I got a CT scan to see if the bone is healed, it’s not. So hardware removal was not an option yet. Arterial duplex confirmed good flow, and so I got her admitted for presumed osteomyelitis, scheduled a 2-stage procedure 1 week apart. First stage consisted of the following:

Debridement
Flap elevation
Skin substitute application to cover the donor site
Antibiotic cement application

Second stage was a repeat debridement, removal of cement, and inset of the flap.

Cultures grew skin contaminant, biopsy was negative. I didn’t get MRI because post-surgical changes and presence of hardware were definitely going to reduce specificity of detecting osteomyelitis. She was eventually discharged on oral antibiotics.

During the recovery, she had no edge necrosis of the flap, but there was a distal dehiscence that required an in-office revision wound closure. She was not happy about the aesthetics of the closure, but at least we got her healed, otherwise this could become a lot more complicated had the hardware gotten infected.

Common question I get is the glove. I use it to prevent the elevated paddle from healing back into the donor site. Technically I don’t need it since I covered the donor site with Integra, so we already have an interface to prevent the paddle from healing back in. The importance of staging the inset is so that the pedicle can be given time to open up choke vessels to improve the vascularity to the paddle. That 180 degree turn can create a kink which disrupts the pedicle’s vascularity.

This case is a followup from a prior case, scroll 14 rows back to see the 2 posts describing his initial infection and wound that I treated, posted on August 16, 2024.

50M with DM, hammertoe, rubbed a wound in his shoe due to the deformity. It’s down to bone, and obviously MRI will show changes concerning for osteomyelitis. However a common misconception is that osteomyelitis can only be treated with amputation. That is not true, toes can definitely be saved even if confirmed osteomyelitis. The trick is to rely on one clinical question… is it necrotic? Don’t worry about swelling, redness, or pus… those are all signs of the host fighting back. They are reversible. After his short hospital course of IV antibiotics he was sent home on 10 days of doxy and augmentin right after the closure.

So the thing is, a lot of docs would recommend amputating this toe, I know that for a fact because I get second opinions all the time for this exact scenario. And so anything I try has close to zero risk, because if the alternative is a toe amputation, what do I have to lose? Pinning across a zone of infection is typically not recommended, but I’m finding that as long as there is no necrosis or pus after debridement, it doesn’t seed infection. Once the pin comes out, it heals and seal.

Lots of dogma out there, but the host is more resilient than we think. Osteomyelitis shouldn’t be feared, it’s simply misunderstood. Remember, Cierny-Mader classification is based on mostly long bone chronic infection, what most podiatrists deal with are acute contiguous spread bone infection. Completely different. Limb salvage starts by learning to fine tune and reframe what we think is a salvageable toe, only then we can move on to evolving the definition of a salvageable limb.
