Study Design. A retrospective radiographic review of all patients treated by a single surgeon with a three-level anterior cervical discectomy and fusion with plate fixation. Objectives. To compare fusion success rates and pseudoarthrosis results with published data for three-level anterior cervical constructs including; anterior cervical discectomy and fusion with plating (ACDFP) and anterior c...

A 57-year-old woman with neglected high congenital dislocation of the right hip (Figure 1) and a severe dysplasia of the left hip had progressive pain in both hips, leg-length discrepancy and limitation of motion. On the right side there was a subtrochanteric pseudoarthrosis after an osteotomy performed when the patient was 10 years of age. The patient was admitted to our department and the phy...

The human skeleton has a remarkable regeneration capacity. Nevertheless, 5-10 % of the bone fractures fails to heal and develops into a non-union which is a challenging orthopedic complication requiring complex and expensive treatment. This review paper will discuss four different computational models, each capturing a particular clinical case of non-union: non-union induced by reaming of the m...

Congenital malformations such as lumbosacral transitional vertebrae and spina bifida occulta constitute unrare anomalies and could affect the symptomatology of low back pain. A transitional vertebra is characterized by elongation of one or both transverse processes, leading to the appearance ofa sacralized fifth lumbar vertebra or a lumbarized first sacral vertebra. Furthermore, sacral spina bi...

Pseudoarthrosis with bone loss is one of the most challenging orthopaedic problems for surgeons. Bone loss usually leads to technical difficulties during surgery due to instability in the fracture area. Eight patients with pseudoarthrosis of different long bones were operated on by the same surgeon. The median age was 53 years (25-61), and the median time period after the index operation was 21...

Osteogenesis imperfecta (OI) is a rare congenital disease characterized by alterations in bone quality, with susceptibility to fractures, instability, deformities, and osteoarthrosis. Prosthetic surgery in these patients is associated with an abnormally high rate of implant failures. On the other hand, abnormal bone fragility adds to the complexity of revision surgery in such individuals-thus r...

Figure 1 Pelvic radiograph shows fusion of both sacro-iliac joints. Whiskering is present at both ischial tuberosities and rami (arrowheads). Irregularity and sclerosis of the lesser trochanters are arrowed. Hipjoints are concentrically narrowed. chronic low back pain and stiffness, of gradual onset, for 10 years. He was living in China previously, receiving herbal applications and pain killers...
