An 84-year-old female sustained significant lower leg trauma after a fall on a staircase. Intraoperative evaluation revealed a decollement injury. Defined as separation of the skin and subcutaneous tissue, from the underlying fascia, separating the perforating blood vessels from the subcutaneous tissue—with the affected skin area destined for necrosis, if not acted upon. Prompt debridement and primary full-thickness skin grafting of the affected skin were performed within hours. Early recognition and management are often needed, to avoid devastating injuries. This case highlights a successful treatment, and the need to focus on these injuries, as no clinical guidelines exist. Patient medical history The patient, with a history of type 2 diabetes, CKD 5 (Cronic Kidney Disease Stage 5, eGFR < 10, weekly dialysis) and poor skin quality, experienced a fall from standing height on a stone staircase. These factors contributed to a complex decollement injury despite the low-energy trauma. She hit the staircase corresponding to her tibial tuberosity, and a grinding motion during the fall resulted in the visual distal open lesion — only a small proximal wound suggesting where she struck the stairs initially, where the decollement lesion was later discovered to be starting from. The decollement injury is most commenly seen in victims in severe traffic accidents and typically involves opposing, intense forces that tear the skin and the subcutaneous layer away from the underlying fascia, thereby compromising the blood supply to the skin. And is often underdiagnozed and hard to recognize.

Поради

– It is advisable to be thorough in the history taking, and to ask in detail about the patient\’s memories of the fall or injury, as this may provide an indication of the type of injury.

– This approach reduced the overall healing time and hospital stay, preventing a prolonged recovery process.

– The primary treatment saves the patient a secondary Vacuum Sealing Drainage (VAC)-treatment and skin grafting, several hospital admissions, donor site morbidity and longer overall patient recovery

– Careful and correct assessment of the postoperative care plan. Normally VAC-treatment is chosen as the golden standard, over larger lesions or skin grafts.

– Post-operative immobilization and calm regime, till suture removal is crucial for graft adherence

Застереження

– Time is the most important factor in treating decollement lesions, avoiding delayed recognition and treatment of the injury.

– Decollement injuries are fairly rare, and clinicians often get the suspicion due to the trauma mechanism – in this case, the trauma mechanism didn’t indicate such a significant decollement injury, showing that decollement injuries can be hard to detect in a timely manner. In this case it was not detected until during surgery, which could have had substantial consequences if not handled correctly.

– The absence of specialized equipment or sufficient plastic surgical expertise may delay the accurate diagnosis and management of decollement injuries, potentially compromising patient outcomes.

Patient history

The patient, with a history of type 2 diabetes, CKD 5 (Cronic Kidney Disease Stage 5, eGFR < 10, weekly dialysis) and poor skin quality, experienced a fall from standing height on a stone staircase. These factors contributed to a complex decollement injury despite the low-energy trauma. She hit the staircase corresponding to her tibial tuberosity, and a grinding motion during the fall resulted in the visual distal open lesion — only a small proximal wound suggesting where she struck the stairs initially, where the decollement lesion was later discovered to be starting from. The decollement injury is most commenly seen in victims in severe traffic accidents and typically involves opposing, intense forces that tear the skin and the subcutaneous layer away from the underlying fascia, thereby compromising the blood supply to the skin. And is often underdiagnozed and hard to recognize. Decollement lesions are classified into three subtypes: open, closed, and atypical and this case was classified as an open type/atypical type, due to the relatively small open lesion, compared to the extended tissue damage.

Examination

Preoperatively, the wound was described as a 20 cm inverted Y-shaped lesion located anterolaterally on the distal third of the crus. Underneath the skin flaps, the tibial bone and fascia were visible. No decollement injury was initially suspected, but the 20 cm lesion was later shown to be way smaller than the underlaying 40 cm widespread decollement injury.

Pre-operative considerations

Although no overt decollement or avital tissue was apparent initially, the surgical team maintained the patient’s risk factors in mind. Usually these kinds of injuries are treated at high specialty departments, with a multidisciplinary two-step approach. In this case the patient was booked for a regular wound revision, and the type of injury the propagation of the decollement injury was not apparent before having the patient on the operating table

Крок 1 — Mapping out the decollement injury and preparing the full thickness skin graft

Intraoperative assessment of the injury. An underlying decollement injury was found to be showing a 40 cm propagation of the injury, where fascia and tibial bone are visualized. Avital subcutaneous fat, tissue and debris was mapped out. The wound was thoroughly debrided ensuring a healthy, well-vascularized bed. Meticulous hemostasis was achieved, and wound edges were refreshed as needed. The area was irrigated to minimize contamination.
