A Nonhealing Ischial Wound in a Patient Who Cannot Stop Working
A 41-year-old man with T4 AIS A paraplegia for 12 years works as a call-center supervisor and sits 10 hours a day. He has a 4 cm stage 3 ischial ulcer with undermining that has been present for 7 months despite hydrocolloid dressings and 'pressure shifts every 2 hours.' He has a chronic indwelling urethral catheter, recurrent UTIs, BMI 31, albumin 3.0 g/dL, and hemoglobin 10.8 g/dL. He has had two prior flap repairs. He is the sole earner and refuses bed rest. At the wound base there is a new friable, fleshy mass. He asks whether he can have the wound 'cleaned out' and return to work in 2 weeks.
1. Why is this wound not healing, and what is your assessment plan?
Read the worked answer
Nonhealing is multifactorial: unrelieved pressure and shear from 10 hours of sitting, likely inadequate offloading, moisture, malnutrition with low albumin and anemia, possible osteomyelitis, and wound care that does not address depth or undermining. Assess with a probe to bone, contrast MRI or CT, CBC, ESR, and CRP, nutrition labs, seating pressure mapping, and a careful examination for sinus tracts. A swab culture is not useful for diagnosing infection; obtain a tissue biopsy if osteomyelitis is suspected, and a bone biopsy is the gold standard. Also assess spasticity, bowel and bladder moisture, and equipment. The prior flaps and recurrence suggest he needs a different seating and work strategy, not just another dressing.
2. What offloading and surgical options are realistic given his work constraints, and how do you counsel him about the 2-week plan?
Read the worked answer
Options include a pressure-relieving cushion guided by pressure mapping, a tilt-in-space or reclining power wheelchair, a sit-to-stand workstation, and scheduled pressure relief. However, ischial wounds heal best with surgical debridement and, if deep, a flap followed by 6-8 weeks of strict no-sitting; a 2-week return is not realistic. Use shared decision-making: if he cannot take leave, conservative care may keep the wound stable but not heal it, and the risk of osteomyelitis or sepsis rises. Explore disability leave, temporary remote work, or a loaner standing wheelchair. Document the risks of declining surgery and involve social work and occupational health.
3. What is the concern about the new mass, and how does his chronic catheter affect your long-term plan?
Read the worked answer
The new friable mass raises concern for a Marjolin ulcer, a squamous cell carcinoma arising in a chronic wound or scar. Do not treat it with silver nitrate or simple cleaning; biopsy it. Also consider pyogenic granuloma or osteomyelitis with fistulization. His chronic indwelling catheter for 12 years increases the risk of bladder stones, recurrent infection, and squamous cell carcinoma of the bladder. He has hand function at T4 and may be a candidate for intermittent catheterization, but first obtain urodynamics and upper-tract imaging. If he switches, he needs a fluid plan and follow-up. Consider cystoscopy if he has hematuria, and counsel him about the long-term risks of continuing the indwelling catheter.
