Abstract Background In recent years, the modified Dunn osteotomy has gained popularity to treat slipped capital femoral epiphysis (SCFE) with various complication rates. Most studies included patients with different severities. This study aimed to determine (1) the radiological and clinical outcome, (2) the health-related quality of life, and (3) the incidence of avascular necrosis of the femoral head (AVN) in patients with severe chronic or acute on chronic SCFE treated by the modified Dunn procedure. Methods Out of 150 patients with SCFE treated at our institution between 2001 and 2014, 15 patients (mean age 12.9 years (range 11.8–15)) were treated by the modified Dunn procedure. Eight SCFE were chronic and 7 acute on chronic. All slips were severe with a mean Southwick slip angle (SSA) of 67° (range 60–80). Radiographic and clinical outcomes were measured. Mean time of follow-up was 3.8 years (range 1–10). Results Anatomical reduction was achieved in all cases. Good radiological results according to the Stulberg Classification (grade 1 + 2) and the Sphericity Deviation Score (< 30) were found in 9 out of 13 patients at the last follow-up. Clinical and functional outcome analysis revealed good results in 8 out of 10 patients (Harris Hip Score > 80). The quality of life measured by the Nottingham Health Profile (NHP) was described good in 10 out of 10 patients. Four out of 15 patients developed an AVN. Conclusions The modified Dunn procedure has a great potential to restore proximal femur geometry in severe chronic or acute on chronic SCFE. It should be considered only if there is no other possibility to restore proximal femur geometry, as is the case in severe slips, due to the risk of AVN.

Head Neck

Cam morphology of the proximal femur is an abnormal contour of the femoral head-neck junction present in approximately 15% to 25% of the asymptomatic population, predominantly in males. Alpha angle and femoral head-neck offset ratio are 2 objective measurement tools that define cam morphology. Both primary (idiopathic) and secondary cam deformity develops through distinct mechanisms. The cause of primary (idiopathic) cam morphology remains incompletely understood. Mounting evidence suggests that idiopathic cam morphology develops during adolescence through alterations in the capital femoral epiphysis in response to participation in vigorous sporting activity. While the exact cause of epiphyseal extension has not yet been determined, preliminary evidence suggests that epiphyseal extension may reflect a short-term adaptive response to provide stability to the physis at the long-term cost of the development of cam morphology. Commonly recognized causes of secondary cam deformity include frank slipped capital femoral epiphysis, Legg-Calve-Perthes disease, and deformity after fracture of the proximal femur. Recent studies also support subtle slipped capital femoral epiphysis as a unique and silent cause of a small percentage of subjects previously thought to have idiopathic cam deformity.

<p class="abstract">Arthrodiastasis (using external fixator and distraction) has been used for various pathologies including deformity correction/stiff hip/slipped capital femoral epiphysis. Historically this has been used for treatment of Perthes disease. The purpose of our study is to evaluate efficacy of arthrodiastasis in management of stiff hip. A 15 year old boy with stiff hip presented with complaints of pain in the left hip for past 6 months. Radiologically the left proximal femur was found to be deformed with metaphyseal widening, sclerosis and arthritic changes. Hip spanning external fixator using limb reconstruction system was done. Distraction was done at a rate of 1 mm/day. After 2 months, fixator was removed. Hip was mobilized under anaesthesia. Good range of all movements was achieved. Arthrodiastasis seems to be a good option in young adolescent in whom total hip replacement needs to be delayed as much as possible.</p>

Biomechanical Factors

Slipped capital femoral epiphysis (SCFE) is the most common hip disorder affecting adolescent children [1]. The etiology is not fully understood but thought to be multifactorial, related to both biological and biomechanical factors [2]. SCFE occurs when the epiphysis of the proximal femur slips in relation to the metaphysis through the growth plate, causing pain, disability and potential long-term sequellae from joint incongruity. The treatment for SCFE typically involves some form of stabilization procedure using pins, screws, bone grafting, osteotomy, or casting.

Fea Analysis

The manifestation of osteoarthrosis by an abnormality such as hip dysplasia, slipped capital femoral epiphysis (SCFE), coxa vara and Legg-Calve-Perthes disease is one of the leading causes of chronic orthopaedic disability, resulting in billions of dollars in treatment and indirect costs, such as lost wages for the patient [1]. Additionally, these conditions are severely painful, inducing a reduction in range of motion, abnormal gait and consequently, poor quality of life. In patients with SCFE, the proximal femur collapses as a result of epiphyseal displacement, resulting in femoroacetabular impingement and acetabular erosion [1, 2]. Patients with developmental coxa vara (DCV), a pediatric hip disorder, exhibit triplanar deformity of the proximal femur. The abnormal neck–shaft angle and associated change in the articulo-trochanteric distance (ATD) alter the biomechanics of the hip adversely, and is often accompanied by limb length discrepancies [3].
