Displaced lesser trochanter fragment caused profunda femoris vein laceration in an 83-year-old with intertrochanteric fracture.

A case report details the intraoperative management of an 83-year-old male patient presenting with an intertrochanteric fracture. During the procedure, a displaced lesser trochanteric fragment was identified as the cause of significant vascular injury. The fragment resulted in a 3 mm laceration of the profunda femoris vein. Following the initial injury, the patient developed deep vein thrombosis postoperatively. The venous laceration was successfully repaired during the same surgical session. This event underscores the potential for rare vascular complications during hip fracture surgery.

The safety profile in this specific instance included the development of deep vein thrombosis following the venous injury. No other adverse events, discontinuations, or issues regarding tolerability were reported in this single case. The primary outcome was the venous laceration, while the secondary outcome involved the subsequent thrombotic event. These findings are derived from a single observation and do not represent a broader population experience.

Key limitations of this evidence include the small sample size of one patient, which prevents the establishment of general management protocols or statistical conclusions. Because this is an observational case report, causality is inferred from the specific anatomical finding rather than a controlled trial. The practice relevance of this report is to emphasize the critical importance of preoperative imaging review to assess anatomical risks. Vascular injuries are rarely reported but can occur even in the absence of obvious preoperative signs. Clinicians should remain vigilant for such complications during surgical planning and execution.
