Slipped Capital Femoral Epiphysis (SCFE) is a hip disorder occurring primarily in adolescents during their growth spurts. This condition involves the separation of the upper end of the thigh bone, known as the capital femoral epiphysis, from the femoral neck at the growth plate. The epiphysis, or “ball” of the hip joint, slips backward and downward, causing pain, stiffness, and instability in the hip or knee. SCFE requires prompt surgical intervention to prevent the slip from worsening and to avoid long-term complications. Understanding the timeline, from the procedure itself to full rehabilitation, offers clarity for patients and their families facing this diagnosis.
Understanding the Surgical Procedure
The standard surgical approach for Slipped Capital Femoral Epiphysis is in situ fixation, which stabilizes the slipped bone where it lies. This minimally invasive technique involves making a small incision near the hip joint. A single metal screw is then inserted across the growth plate to securely hold the femoral head in its current position. The goal is to prevent any further slippage until the growth plate naturally closes, or fuses.
For most patients with a stable slip, this single-screw method is the definitive treatment. Cases involving an unstable slip, where the patient cannot bear any weight, may necessitate a more involved procedure. Some surgeons also recommend placing a stabilizing screw in the unaffected hip, known as prophylactic fixation, since the risk of a slip occurring on the opposite side is high. This fixation method is considered the gold-standard due to its effectiveness in preventing progression.
The Duration of the Operation
The active surgical time for in situ fixation often ranges from 45 to 90 minutes because it is a percutaneous and fluoroscopically guided technique. The procedure is considered straightforward for an experienced orthopedic surgeon. Factors like the severity of the slip, specifically whether it is stable or unstable, can influence the duration.
The total time a patient spends in the operating suite is longer than the active surgical time. This comprehensive period includes general anesthesia induction, patient positioning, the surgical procedure itself, and recovery from anesthesia. Patients should expect to be in the operating room environment for a total of approximately two to three hours. If prophylactic fixation of the opposite hip is performed simultaneously, the total time will increase accordingly.
Immediate Post-Operative Hospital Stay
Following the procedure, the patient is moved to the Post-Anesthesia Care Unit (PACU). Nurses closely monitor the patient’s vital signs, pain level, and circulation in the affected leg. Managing post-surgical pain is a primary focus, utilizing a combination of oral and intravenous pain medications. The patient is typically given crutches or a walker and instructed on non-weight bearing or protected weight bearing status before leaving the hospital.
The typical hospital stay after uncomplicated in situ fixation is brief, lasting between one and three days. Early mobilization is encouraged, starting with sitting up and moving to a chair shortly after surgery. Physical therapists begin instruction on safe movement and the proper use of mobility aids. The goal is to achieve adequate pain control, ensure no immediate complications are present, and confirm the patient can safely manage their prescribed weight-bearing restrictions at home.
The Full Recovery and Rehabilitation Timeline
The long-term recovery timeline is significantly affected by the patient’s adherence to weight-bearing restrictions. For a stable slip treated with a single screw, the period of non-weight bearing or protected weight bearing typically lasts for six to eight weeks. This restriction is necessary to allow the growth plate to fuse around the stabilizing screw.
Patients can often return to school and resume most non-strenuous daily activities within three to five days of being discharged from the hospital. Physical therapy focuses on maintaining hip range of motion and strengthening the surrounding muscle groups. As the bone heals, the patient will gradually transition from non-weight bearing to partial weight bearing, and eventually to full weight bearing under the guidance of the orthopedic surgeon.
A complete return to vigorous sports and high-impact activities, such as running and contact sports, usually takes four to six months. Clearance for unlimited activity depends on radiographic evidence showing the growth plate has completely closed. The full recovery timeline is highly individualized, depending on the initial severity of the slip and the patient’s progress through physical therapy.
