Renal osteodystrophy.

The incidence of chronic renal disease is increasing, and the pattern of renal osteodystrophy seems to be shifting from the classic hyperparathyroid presentation to one of low bone turnover. Patients with persistent disease also live longer than previously and are more physically active. Thus, patients may experience trauma as a direct result of increased physical activity in a setting of weakened pathologic bone. Patient quality of life is primarily limited by musculoskeletal problems, such as bone pain, muscle weakness, growth retardation, and skeletal deformity. Chronic renal disease also increases the risk of comorbidity, such as infection, bleeding, and anesthesia-related problems. Current treatment strategies include dietary changes, plate-and-screw fixation, and open reduction and internal fixation.

Occult bilateral acetabular fractures associated with high-energy trauma and osteoporosis.

Acetabular fractures that are radiographically occult are associated with osteoporosis, low-energy trauma, and advanced age. We present a case of bilateral occult acetabular fractures in a 65-year-old woman who presented with an open tibia-fibula fracture and compartment syndrome and thoracolumbar spine fractures sustained in a motor vehicle accident. Initial radiographs of the pelvis and a pelvic CT scan did not show any bony injuries when the films were reviewed prospectively. At 6 weeks after injury, a CT scan and plain radiographs showed bilateral healing transverse acetabular fractures with acetabular protrusio on the left. At most recent follow-up, the patient had posttraumatic hip arthritis with moderate protrusio on the left and was ambulating with a cane. Total hip arthroplasty is anticipated in the future.

Osteochondral lesions of the talus.

Osteochondral lesions of the talus occur infrequently and usually represent late sequelae of ankle trauma. Because of the functional significance of the talus and its limited capacity for repair, correct early diagnosis is important. Osteochondral fractures should be suspected in patients with chronic ankle pain, especially those with a prior ankle injury. Historically, plain radiographs have been used to stage lesions; more recently, magnetic resonance imaging and arthroscopy have been used. Non-surgical management remains the mainstay of treatment of acute, nondisplaced osteochondral lesions. Surgical management is reserved for unstable fragments or failure of nonsurgical treatment. Recent advances in osteochondral grafting have allowed reconstruction of the talar dome, leading to more predictable relief of pain and improvement of function.
