A 16-year-old female sustained a crush injury of the left upper extremity, resulting in an open humeral fracture (Gustilo–Anderson IIIC), brachial artery injury, and extensive soft-tissue loss. Initial treatment by trauma and vascular surgery included external fixation and brachial artery reconstruction using a saphenous vein graft. Early graft thrombosis led to critical limb ischemia, and above-elbow amputation was proposed. An emergency limb salvage attempt was performed using a combined free vastus lateralis and anterolateral thigh flap. The limb was successfully salvaged, with a favorable contour and good long-term functional outcome after secondary debulking procedures. Patient medical history A 16-year-old previously healthy female sustained a crush injury to the left upper extremity, resulting in an open humeral fracture (Gustilo–Anderson IIIC), brachial artery injury, and extensive soft-tissue loss [1,2]. Initial management by the trauma and vascular surgery teams at the same hospital included external fixation to stabilize the humeral fracture and reconstruction of the brachial artery using a saphenous vein interposition graft. Early thrombosis of the vein graft led to critical limb ischemia, and above-elbow amputation was subsequently proposed. Before and After Patient examination On examination by the plastic surgery team, the left upper extremity showed extensive soft-tissue loss around the elbow and proximal forearm, with the humerus stabilized in an external fixator. Despite the thrombosis of the brachial artery interposition graft,

Поради

• Successful limb salvage in complex trauma depends not only on surgical technique, but on close interdisciplinary coordination between trauma surgery, vascular surgery, plastic surgery, and anesthesia. In this case, standard trauma and vascular algorithms would have led to amputation, whereas a reconstructive perspective allowed a different, limb-preserving solution.
• Anesthetic stabilization is a critical enabler of complex emergency reconstruction. Without rapid hemodynamic control and intraoperative support, microsurgical limb salvage in critically injured patients is often not feasible [5].
• The combination of an anterolateral thigh flap with a vastus lateralis muscle component provides both surface coverage and deep tissue volume, which is particularly valuable in young, thin patients where an ALT flap alone may be insufficient to reconstruct extensive three-dimensional soft-tissue defects.
• In emergency limb-salvage situations, a pragmatic reconstructive strategy focused on the patient and on reasonable operative time is essential. Although highly sophisticated designs such as chimeric ALT–vastus lateralis flaps offer maximal intraoperative flexibility, their preparatory complexity may not be justified in critically injured patients. In our case, a myocutaneous ALT flap incorporating the vastus lateralis muscle, combined with staged secondary debulking, achieved a comparable long-term functional and contour outcome with a substantially shorter initial operative time [6-8].
• In young patients, a more aggressive and reconstructive-first strategy can yield a disproportionally large long-term benefit, transforming an otherwise life-long disability into a functional extremity.

Застереження

• Relying exclusively on emergency and trauma algorithms can result in amputation in cases where residual perfusion and tissue viability still permit salvage. Multidisciplinary reassessment is essential in borderline situations.
• Venous interposition grafts carry a substantial risk of early thrombosis and therefore require close postoperative surveillance. Graft failure should prompt immediate reassessment of limb viability rather than automatic abandonment of reconstruction.

Patient history

A 16-year-old previously healthy female sustained a crush injury to the left upper extremity, resulting in an open humeral fracture (Gustilo–Anderson IIIC), brachial artery injury, and extensive soft-tissue loss [1,2]. Initial management by the trauma and vascular surgery teams at the same hospital included external fixation to stabilize the humeral fracture and reconstruction of the brachial artery using a saphenous vein interposition graft. Early thrombosis of the vein graft led to critical limb ischemia, and above-elbow amputation was subsequently proposed.

Examination

On examination by the plastic surgery team, the left upper extremity showed extensive soft-tissue loss around the elbow and proximal forearm, with the humerus stabilized in an external fixator. Despite the thrombosis of the brachial artery interposition graft, the hand was still warm with delayed but present capillary refill, indicating residual distal perfusion through collateral arterial flow.

Pre-operative considerations

After early thrombosis of the saphenous vein interposition graft, the limb fulfilled the criteria of a mangled extremity with major vascular injury, open fracture, and extensive soft-tissue destruction. According to institutional trauma algorithms and established trauma scoring systems used in severely injured patients, the extremity was considered to carry a very high risk of limb loss and systemic morbidity, and above-elbow amputation was therefore proposed by the trauma and vascular surgery teams [3,4].
However, in view of the preserved distal perfusion, the patient’s young age, absence of comorbidities, and the presence of viable tissue, a limb-salvage strategy was considered technically feasible by the plastic surgery team. An emergency microsurgical reconstruction using a combined free vastus lateralis and anterolateral thigh flap was therefore selected to preserve the extremity and its function.

Крок 1 — Step 1 Radical debridement: Extensive debridement of all non-viable soft tissue exposing the humerus, muscles, and vascular structures.

All necrotic tissue was excised until viable bleeding muscle and soft tissue were reached. The wound was converted into a clean, reconstructable defect measuring approximately 19 x 12 cm.

Post-operative plan

• Following emergency reconstruction, the patient underwent intensive clinical flap monitoring and general condition stabilization. Early referral to hand therapy and occupational therapy was initiated to preserve joint mobility and hand function.
• Given the initial volume of the transferred tissues, staged secondary debulking procedures were planned and performed at appropriate intervals to refine contour, improve range of motion, and optimize the silhouette of the reconstructed forearm. Secondary contour refinement is an integral part of successful limb reconstruction, not a complication.
• Long-term follow-up focused on functional recovery, scar management, and progressive rehabilitation, ultimately allowing the patient to return to daily activities and professional life with preserved use of her left hand.
