Read the below given passage carefully and answer question from strictly as per the content of the paragraph:
Slipped capital femoral epiphysis is a displacement of the femoral head from the femoral neck because of a weakness in the epiphyseal plate. The approximate age range this condition occurs is ages 13 to 16 in boys and ages 11 to 14 in girls (Loder et al., 1993). It is seen in youths who have predisposing factors such as a recent growth spurt, an imbalance of sex hormones and growth hormones, and who are overweight or have a lanky build. The patient reports an insidious, gradual onset of pain in the groin that can refer to the thigh and knee in chronic slips. Less often, the patient experiences an acute slipped capital femoral epiphysis that presents with a sudden onset of pain and disability following a traumatic event. Pain produces an antalgic gait. Examination reveals restriction of hip medial rotation, abduction, and flexion, with the greatest restriction in medial rotation. During active hip flexion, the hip also moves into lateral rotation. In a relaxed position, the leg is in greater lateral rotation than the contralateral limb. Hip abductors are weak. Possible differential diagnoses with groin, anterior thigh, and knee pain must be investigated. Other possible diagnoses are fracture, tumor, hernias, strains, and contusions. An evaluation of the patient's history, hip motion, motion patterns, pain level, and strength helps the clinician determine other possible sources of the patient's pain. Treatment includes open reduction and internal fixation followed by partial weight bearing for two to six weeks. Isometric exercises immediately postoperatively, followed by open kinetic chain exercises, are used early in the rehabilitation process. Aquatic exercises after the surgical incision has healed and the patient is still partial weight bearing are used to achieve range-of- motion and strength gains. Once full weight bearing is permitted, the patient continues to use the crutches until normal gait and hip control are evident. Stork standing and other proprioception exercises progress as tolerated when unilateral weight-bearing activities are permissible. The therapeutic exercise progression follows that for other fractures once the patient is full weight bearing.
