Case Study:Successful Treatment of A Humeral Head Fracture in Mexico

Introduction

At the State Hospital of Tamaulipas, Mexico, a 55-year-old male patient suffered a humeral head fracture caused by an accidental fall. The surgery was successfully performed by Dr. Luis Rodriguez using CZMEDITECH’s Multi-lock Humeral Intramedullary Nail System, achieving excellent fixation stability and rapid postoperative recovery.

Preoperative Evaluation

Preoperative imaging revealed a displaced humeral head fracture with significant misalignment. After comprehensive evaluation, Dr. Rodriguez planned a minimally invasive intramedullary fixation using CZMEDITECH’s Multi-lock Humeral Nail to restore the joint’s anatomical structure and promote early rehabilitation.

Surgical Procedure

A minimally invasive approach was used to access the fracture site. The Multi-lock Humeral Intramedullary Nail was inserted under fluoroscopic guidance, followed by multiple locking screws to achieve strong three-dimensional fixation. Intraoperative imaging confirmed excellent alignment and implant stability.

Postoperative Care and Recovery

Postoperative X-rays demonstrated ideal alignment and solid fixation. The patient began passive shoulder motion on day 3 and started active rehabilitation two weeks later. At the six-week follow-up, shoulder function had recovered by more than 80%, with no loosening or infection observed.
