ICD-10: M93.05

Acute on chronic slipped upper femoral epiphysis (SUFE), classified under ICD-10 code M93.05, is a condition primarily affecting adolescents and is characterized by the displacement of the femoral head due to slippage at the growth plate. This condition can present acutely on a background of chronic instability, leading to a range of clinical manifestations. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this condition.

Clinical Presentation

Patient Demographics

• Age Group: Typically occurs in adolescents, particularly between the ages of 10 and 16 years.
• Gender: More common in males than females, with a ratio of approximately 2:1 to 3:1.
• Obesity: Often associated with obesity, which can increase the risk of developing SUFE due to increased mechanical stress on the hip joint.

Signs and Symptoms

1. Hip Pain:
   - Patients often report pain in the hip, groin, or knee. The pain may be acute in onset or may have been present for a longer duration, indicating a chronic condition.
   - Pain can be exacerbated by activity and may lead to a reluctance to bear weight.

2. Limited Range of Motion:
   - There is typically a reduction in internal rotation of the hip, which can be assessed during physical examination.
   - Patients may exhibit a preference for external rotation of the affected leg.

3. Limping:
   - Affected individuals often present with a limp, which may be due to pain or mechanical instability in the hip joint.

4. Leg Positioning:
   - The affected leg may appear shorter and externally rotated compared to the contralateral leg.

5. Acute Symptoms:
   - In cases of acute on chronic SUFE, patients may experience sudden worsening of symptoms, including increased pain and inability to walk.

Additional Clinical Features

• Swelling and Tenderness: There may be localized swelling and tenderness around the hip joint.
• Muscle Spasms: Patients may exhibit muscle spasms around the hip due to pain and instability.

Diagnostic Considerations

• Imaging: Diagnosis is typically confirmed through X-rays, which may show displacement of the femoral head. MRI may be used in some cases to assess the extent of slippage and any associated complications.
• Differential Diagnosis: It is important to differentiate SUFE from other conditions such as septic arthritis, osteomyelitis, or trauma-related injuries.

Acute on chronic slipped upper femoral epiphysis (SUFE) is a specific condition classified under the ICD-10 code M93.05. This condition is characterized by the displacement of the femoral head due to slippage at the growth plate, which can occur acutely on a background of chronic slippage. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

Acute on chronic slipped upper femoral epiphysis refers to a situation where a patient has a history of chronic slipped capital femoral epiphysis (SCFE) that suddenly worsens, leading to an acute episode of instability. This condition is particularly concerning as it can lead to significant complications if not addressed promptly.

Pathophysiology

In SUFE, the femoral head slips off the neck of the femur at the growth plate (physis). This slippage can be chronic, where the displacement occurs gradually over time, or acute, where there is a sudden worsening of the condition. The unstable variant indicates that the femoral head is not securely positioned, increasing the risk of avascular necrosis and other complications.

Symptoms

Patients with acute on chronic SUFE may present with:
- Hip Pain: Often localized to the groin or thigh, which may be exacerbated by movement.
- Limited Range of Motion: Particularly in internal rotation and abduction of the hip.
- Limping: Due to pain and instability, patients may exhibit a limp or altered gait.
- Leg Positioning: The affected leg may appear externally rotated.

Diagnosis

Diagnosis typically involves:
- Clinical Examination: Assessment of hip range of motion and pain response.
- Imaging Studies: X-rays are the primary diagnostic tool, revealing the degree of slippage and any associated changes in the femoral head. MRI may be used to assess for avascular necrosis or other complications.

Treatment

Management of acute on chronic SUFE often requires surgical intervention, particularly if the condition is unstable. Treatment options include:
- Surgical Stabilization: This may involve in situ fixation with screws to stabilize the femoral head and prevent further slippage.
- Monitoring: In some cases, if the condition is stable, careful monitoring may be appropriate.

Conclusion

Acute on chronic slipped upper femoral epiphysis (ICD-10 code M93.05) is a serious condition that necessitates prompt diagnosis and intervention to prevent complications such as avascular necrosis. Understanding the clinical presentation, diagnostic methods, and treatment options is crucial for effective management of this condition. If you suspect a case of SUFE, it is essential to refer the patient for appropriate imaging and orthopedic evaluation to ensure timely care.

Acute on chronic slipped upper femoral epiphysis (SUFE), classified under ICD-10 code M93.05, is a condition primarily affecting adolescents, characterized by the displacement of the femoral head due to slippage at the growth plate. This condition can lead to significant complications if not treated appropriately. Here, we will explore the standard treatment approaches for this condition, including both surgical and non-surgical options.

Understanding Acute on Chronic Slipped Upper Femoral Epiphysis

Definition and Causes

Acute on chronic SUFE occurs when there is a sudden worsening of a previously stable condition, often due to factors such as hormonal changes, obesity, or mechanical stress on the hip joint. The instability of the epiphysis can lead to severe pain and functional impairment, necessitating prompt intervention to prevent further complications, including avascular necrosis of the femoral head[1].

Standard Treatment Approaches

1. Initial Assessment and Diagnosis

Before treatment, a thorough assessment is essential. This typically includes:
- Clinical Evaluation: Assessing symptoms such as hip pain, limited range of motion, and any history of previous episodes.
- Imaging Studies: X-rays are the primary diagnostic tool, often supplemented by MRI to evaluate the extent of slippage and any associated complications[2].

2. Non-Surgical Management

In cases where the condition is stable and the patient is not experiencing severe symptoms, non-surgical management may be considered:
- Activity Modification: Patients are advised to limit weight-bearing activities to reduce stress on the hip joint.
- Pain Management: Analgesics and anti-inflammatory medications can help manage pain and inflammation.
- Physical Therapy: Gentle range-of-motion exercises may be introduced to maintain joint function without exacerbating the condition[3].

3. Surgical Intervention

Surgical treatment is often necessary for unstable cases or when there is significant slippage. The primary surgical options include:

a. In Situ Fixation

• Procedure: This involves the placement of screws to stabilize the femoral head in its proper position. The goal is to prevent further slippage and allow for continued growth of the femoral head.
• Indications: Typically indicated for acute on chronic cases where the epiphysis is unstable but not severely displaced[4].

b. Osteotomy

• Procedure: In more severe cases, an osteotomy may be performed to realign the femoral head and improve joint mechanics.
• Indications: This is usually reserved for cases with significant deformity or when in situ fixation is not feasible[5].

4. Postoperative Care

Post-surgery, patients require careful monitoring and rehabilitation:
- Weight Bearing: Gradual reintroduction of weight-bearing activities is essential, often starting with crutches or a walker.
- Physical Therapy: A structured rehabilitation program is crucial to restore strength and mobility while preventing complications such as stiffness or muscle atrophy[6].

5. Long-term Follow-up

Regular follow-up appointments are necessary to monitor the healing process and assess for any potential complications, such as avascular necrosis or osteoarthritis, which can develop later in life due to the initial condition[7].

Conclusion

The management of acute on chronic slipped upper femoral epiphysis (ICD-10 code M93.05) requires a tailored approach based on the severity of the condition and the individual patient's needs. While non-surgical options may suffice in stable cases, surgical intervention is often necessary for unstable presentations to prevent long-term complications. Continuous follow-up and rehabilitation are critical to ensure optimal recovery and function. If you suspect this condition, consulting with an orthopedic specialist is essential for appropriate diagnosis and treatment planning.
