Bedsores over Seat Bone (Ischium)

About Bedsores over Seat Bone (Ischium)

Ischial bedsores develop when a person sits in the same position on a bed or wheelchair for prolonged periods. They typically appear on one or both sides of the ischial bone, often with a deep core on one side and more superficial change on the other. As an experienced pressure ulcer surgery lucknow team, we evaluate location, depth, and signs of bone involvement, since the seat bone is particularly prone to chronic, recurrent ulcers under sitting pressure.

Most patients with ischium ulcer treatment needs have spinal injuries that affect the lower half of the body, leaving them paraplegic and dependent on wheelchairs. Others may be acutely unwell, recovering from major trauma, fractures, or strokes, or affected by old age. The common factor is sustained pressure at the ischium without the protective shifting of weight that an able-bodied person performs unconsciously many times each hour.

Sitting bone wound care begins with stage-based assessment. Category I and II ulcers may be managed without admission when comorbidities are well controlled, using structured dressings, education on positioning, and frequent early reviews. Patients with chronic bedsore treatment requirements or Category III and IV ulcers usually need hospital admission, full nutritional and surgical workup, pre-anaesthetic clearance, and consultation with neurology, cardiology, or general medicine before surgery is planned.

Surgical correction may be performed in a single stage where the wound is well prepared, or as a two-stage procedure when the wound is heavily infected or the patient is not initially fit for flap reconstruction. Two-stage care typically involves debridement and negative pressure wound therapy for several days, followed by flap coverage once the bed is healthy. Home care, air mattresses, and side-to-side turning remain essential throughout the recovery period.

What to expect

• Detailed assessment of wound stage, sitting habits, neurological status, and comorbidities.
• Investigations including cultures, blood tests, and imaging to detect bone involvement.
• Conservative care with dressings and home-care education for stable, early-stage ulcers.
• Single- or two-stage surgical correction with debridement, VAC therapy, and flap coverage as needed.
• Structured follow-up plan including air mattress use, repositioning, and review schedule.

Recovery

• Strict avoidance of sitting on the operated side until cleared by the surgeon.
• Air mattresses, regular turning, and meticulous skin care are essential throughout recovery.
• Nutrition, diabetes control, and infection management directly influence healing.
• Long-term follow-up helps detect early skin changes and prevent recurrence at adjacent sites.
