We report a case of an 18-year-old male patient with no records of medical history. Five months before being admitted to the hospital, the patient began to experience progressive weakness and paralysis in finger extension movements. The patient was diagnosed with posterior interosseous nerve entrapment syndrome and was indicated for nerve release surgery. During the surgery, we found that the patient's posterior interosseous nerve was compressed by the Leash of Henry and by the fibrous band of the supinator muscle at the Arcade of Frӧhse, where the interosseous nerve passes through the supinator. The posterior interosseous nerve was completely released at five most compressed sites, and the patient was discharged after one day with a follow-up appointment and scheduled rehabilitation sessions.

Although fluoroscopic-guided SIJ injections remain the gold standard for both diagnostic and therapeutic purposes, their availability may be limited by insurance barriers or logistical constraints. In such cases, alternative approaches such as ultrasound-guided or landmark-based injections may offer practical, rapid solutions in outpatient settings.
