A Rare Case of Awkward Gait: The Tethering Effect of a Unilateral Iliofemoral Fibrous Band.

Case: A young girl without pertinent medical history presented with a leg length discrepancy and an awkward gait disturbance. After a rapid growth spurt during the following year, other symptoms became obvious, she developed an inability to sit crossed legged, and her range of motion of the left hip decreased. Hip magnetic resonance imaging demonstrated a left unilateral fibrous band between the iliac wing and the greater trochanter.

Does Adjunction of Autologous Osteoblastic Cells Improve the Results of Core Decompression in Early-stage Femoral Head Osteonecrosis? A Double-blind, Randomized Trial.

Background: Osteonecrosis of the femoral head (ONFH) is a disabling disease that can ultimately progress to collapse of the femoral head, often resulting in THA. Core decompression of the femoral head combined with cell therapies have shown beneficial effects in previous clinical studies in patients with early-stage (Association Research Circulation Osseous [ARCO] Stage I and II) ONFH. However, high-quality evidence confirming the efficacy of this treatment modality is still lacking.

[Rotationplasty as an alternative to amputation].

Rotationplasty can be used as an alternative to amputation when conservative treatment is not possible, for example in malignant tumours of the knee. The principle of the operation is to rotate the lower leg through 180 ° after resection of the distal femur and in this way the ankle joint replaces the knee joint. This surgical technique, although complex, allows satisfactory carcinological resection with a functional outcome superior to amputation above the knee as well as a better quality-of-life.

[How I explore... protrusio acetabuli in children].

Protrusio acetabuli is a clinical entity with variable clinical presentation consisting of a medial deviation of the acetabulum in the pelvic direction. Qualified as a silent deformity in view of its asymptomatic nature until the onset of early degenerative changes, the patient will present with progressive joint pain and stiffness until the development of secondary osteoarthritis. In view of the potentially destructive primary causes associated with the development of secondary protrusion acetabuli, the radiological demonstration of this pathology in young patients cannot be neglected and should lead to the investigation of the underlying pathologies associated with this anomaly.

Use of synthetic ligament in reconstruction after massive bone tumour removal.

With advances in medical imaging over the past decades and with a multidisciplinary approach in bone tumour management, limb sparing procedures are more often feasible but come with new challenges. One of these is to deal with the remaining soft tissues, especially muscles, or bony parts and to restore continuity and a correct function. Synthetic ligaments have been used safely for several decades in various ligament reconstruction procedures with good results.
