Real-World Examples of NUSS Usage
Understanding how the Non-Union Scoring System (NUSS) is applied in real-world scenarios can highlight its impact on treatment outcomes for patients with non-union fractures. By examining specific cases and data, we can see how the NUSS protocol aids in medical decision-making and enhances clinical outcomes.
Key Points on NUSS Usage
1. Effective Healing Rates: Patients classified under Class I of the NUSS protocol saw a remarkable radiographic healing rate of 100%, with a mean time to healing of just 8.78 ± 2.04 months. This represents the importance of appropriate classification upon initial assessment.
2. Class II Success: In Class II, patients experienced a healing rate of 93.5%, indicating that a combination of mechanical correction and biological treatment significantly supports fracture healing.
3. Dealing with Severe Cases: Even in more complex cases classified as Class III, where patients had a lower healing rate of 82.1%, effective combinations of treatments still achieved a notable success rate. Understanding these classifications helps guide doctors in selecting the most appropriate intervention strategies.
4. Ongoing Research and Findings: Data show that 91% of patients in Class I achieved significant improvements with selected protocols, emphasizing the necessity of individualized treatment plans based on NUSS scoring.
