ICD-10: M93.043

Acute slipped upper femoral epiphysis (SUFE), classified under ICD-10 code M93.043, is a significant orthopedic condition primarily affecting adolescents. This condition involves the displacement of the femoral head due to slippage at the growth plate (physis), which can lead to various complications if not addressed promptly.

Clinical Description

Definition

Acute slipped upper femoral epiphysis is characterized by the sudden displacement of the femoral head from its normal position in the acetabulum, typically occurring in children and adolescents during periods of rapid growth. The term "unstable" indicates that the displacement is not fixed and can lead to further complications, including avascular necrosis of the femoral head if not treated effectively[1][4].

Etiology

The exact cause of acute SUFE is not fully understood, but it is believed to be multifactorial, involving mechanical, hormonal, and genetic factors. It is more prevalent in overweight adolescents and those undergoing rapid growth spurts. Hormonal changes during puberty may also play a role in the weakening of the growth plate, making it more susceptible to slippage[1][5].

Symptoms

Patients with acute SUFE typically present with:
- Sudden onset of hip or groin pain, which may radiate to the knee.
- Limited range of motion in the hip joint, particularly internal rotation.
- Affected limb may appear externally rotated and shortened.
- Patients may exhibit a limp or difficulty bearing weight on the affected side[1][4].

Diagnosis

Diagnosis is primarily clinical, supported by imaging studies. X-rays are the standard diagnostic tool, revealing the degree of slippage and any associated complications. In some cases, MRI may be utilized to assess the condition of the femoral head and surrounding structures, especially if there is concern for avascular necrosis[1][4].

Treatment

The management of acute SUFE focuses on stabilizing the femoral head and preventing further slippage. Treatment options include:
- Surgical Intervention: The most common approach is surgical fixation using screws to stabilize the femoral head in its proper position. This is crucial to prevent complications such as avascular necrosis and osteoarthritis.
- Non-Surgical Management: In some cases, particularly if the slip is minimal and the patient is not symptomatic, non-surgical management may be considered, including activity modification and close monitoring[1][4].

Prognosis

The prognosis for patients with acute SUFE largely depends on the timing of diagnosis and intervention. Early treatment typically results in better outcomes, while delayed treatment can lead to significant complications, including chronic pain and joint dysfunction. Long-term follow-up is essential to monitor for potential complications such as osteoarthritis or avascular necrosis[1][5].

In summary, acute slipped upper femoral epiphysis (ICD-10 code M93.043) is a serious condition that requires prompt recognition and treatment to prevent long-term complications. Understanding its clinical presentation, diagnostic criteria, and management strategies is crucial for healthcare providers involved in pediatric orthopedics.

Acute slipped upper femoral epiphysis (SUFE), particularly the unstable type, is a significant orthopedic condition primarily affecting adolescents. This condition is characterized by the displacement of the femoral head due to slippage at the growth plate (physis) of the femur. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with ICD-10 code M93.043.

Clinical Presentation

Patient Demographics

• Age Group: Typically occurs in adolescents aged 10 to 16 years, with a higher prevalence in males.
• Growth Spurts: Often coincides with periods of rapid growth, making it more common during puberty.
• Obesity: There is a notable association between obesity and the incidence of SUFE, as excess weight can increase stress on the hip joint.

Signs and Symptoms

• Hip Pain: Patients often present with hip pain that may be acute or gradually worsening. The pain can be localized to the hip or referred to the knee.
• Limited Range of Motion: There is usually a significant reduction in the range of motion of the hip joint, particularly in internal rotation and abduction.
• Limping: Affected individuals may exhibit a limp, which can be due to pain or mechanical instability of the hip.
• Leg Positioning: The affected leg may appear externally rotated and shortened compared to the contralateral leg.

Acute Presentation

• Unstable Condition: In cases classified as unstable, there is a higher risk of avascular necrosis of the femoral head due to compromised blood supply. This can lead to more severe symptoms and complications.
• Acute Onset: Symptoms may develop suddenly, often following minimal or no trauma, which can lead to confusion with other conditions.

Diagnostic Considerations

• Imaging: Diagnosis is typically confirmed through X-rays, which may show displacement of the femoral head. MRI may be utilized in cases where the diagnosis is uncertain or to assess the degree of instability and potential complications.
• Differential Diagnosis: It is essential to differentiate SUFE from other conditions such as transient synovitis, osteomyelitis, or fractures.

Understanding Acute Slipped Upper Femoral Epiphysis

Definition and Symptoms

Acute slipped upper femoral epiphysis occurs when the femoral head slips off the neck of the femur at the growth plate, often presenting with symptoms such as hip pain, limited range of motion, and sometimes referred pain to the knee. The "unstable" designation indicates that the slip is severe, potentially leading to avascular necrosis of the femoral head if not addressed quickly[1].

Standard Treatment Approaches

1. Initial Assessment and Diagnosis

Before treatment, a thorough assessment is essential. This typically includes:
- Clinical Examination: Evaluating the range of motion and pain levels.
- Imaging Studies: X-rays are the primary diagnostic tool, often supplemented by MRI if there is concern for avascular necrosis or to assess the degree of slippage[2].

2. Non-Surgical Management

In cases where the slip is stable, non-surgical management may be considered:
- Activity Modification: Patients are advised to limit weight-bearing activities to prevent further slippage.
- Pain Management: Analgesics or anti-inflammatory medications can help manage pain and discomfort[3].

3. Surgical Intervention

For unstable slips or when conservative management fails, surgical intervention is typically required:
- In Situ Fixation: The most common surgical approach involves the insertion of screws to stabilize the femoral head in its proper position. This procedure aims to prevent further slippage and to allow for continued growth of the femur[4].
- Timing of Surgery: Prompt surgical intervention is crucial, ideally within days of diagnosis, to minimize complications such as avascular necrosis[5].

4. Postoperative Care

Post-surgery, the following care is essential:
- Rehabilitation: A structured physical therapy program is initiated to restore range of motion and strength while ensuring the hip is protected during the healing process.
- Follow-Up Imaging: Regular follow-up with X-rays is necessary to monitor the position of the femoral head and the healing process[6].

5. Long-Term Management

Patients may require long-term follow-up to monitor for potential complications, including:
- Avascular Necrosis: This is a significant risk following an unstable slip and requires ongoing assessment.
- Osteoarthritis: Patients are at increased risk for developing hip osteoarthritis later in life, necessitating monitoring and potential intervention[7].

Conclusion

Acute slipped upper femoral epiphysis, particularly in its unstable form, requires prompt and effective treatment to prevent long-term complications. The standard treatment approaches involve a combination of careful assessment, potential surgical intervention, and comprehensive postoperative care. Early diagnosis and intervention are critical to ensuring the best possible outcomes for affected adolescents. Regular follow-up is essential to monitor for complications and to support the patient's recovery and long-term health.
