Reversal of the histology of bone after parathyroidectomy in patients with hyperparathyroidism.

Hyperparathyroidism is commonly seen in patients with end-stage renal disease and less commonly in the primary form. The skeletal manifestations of hyperparathyroidism are the same in both forms and are well described in the literature. We treated a patient from each category. Multiple bony lesions and pathologic fractures were observed. The clinical presentations and radiologic and histologic findings confirmed the diagnosis of hyperparathyroidism and osteitis fibrosa cystica in both patients. Subtotal excisions of the parathyroid glands were done in both patients. Appropriate treatment of the bony lesions and pathologic fractures resulted in healing. Histologic evaluation of the bony lesions indicated an osteoblastic or healing response. The reversal of the histologic pattern in just 5 days and 16 days after parathyroidectomy was noted. In treating such patients, physicians should consider parathyroidectomy as an aid in the overall management of patients.

Talar neck fracture.

Despite advancement in the knowledge and understanding of talar neck fracture biomechanics and refined techniques of treatment, a significant number of patients with these fractures have long term complications. Anatomic reduction is the goal in all situations where possible. Careful follow-up of patients is mandatory to prevent unrecognized displacement of the fracture fragment as the swelling of the extremity subsides in the cast. Weight bearing should be delayed until radiographic union of the fracture is apparent, if possible. There is a tendency today towards increased use of open reduction and internal fixation of talar neck fractures. This more aggressive approach appears to give patients the best chance for healing without complications. The results of open reduction and internal fixation studies seem to show better maintenance of the fracture reduction, reduction of time until fracture union, and overall better long-term results. Careful assessment of tibiotalar, subtalar, and talonavicular joints is essential prior to any salvage procedure. The use of CT scans, MRI's, and plain tomograms seems to be of most help in assessment of these patients prior to arthrodesis or other salvage procedures. The incidence of poor results following talar neck fracture still continues to remain high, unfortunately, despite the advancement in the understanding and knowledge of these fractures.

Technique of reduction and internal fixation of thoracolumbar fracture-dislocation using pedicle screws and variable screw placement plates.

Spinal column injuries to the thoracolumbar region are common and leave one fifth of patients with neurological deficit. The authors describe a case of complete fracture-dislocation at lumbar 1-2 level with paraplegia. They detail their surgical technique for reduction, stabilization, and fusion using pedicle screws and plates. Surgical management of such injuries allows rapid rehabilitation of patients with spinal column injuries.

Failure of a polyethylene total knee component presenting as a thigh mass. Report of a rare complication of total knee arthroplasty.

Early failure caused by wear of the polyethylene bearing surface of a metal-backed tibial platform or a metal-backed patellar component in a total knee prosthesis has been a recognized complication; patients with these problems initially have pain and instability. A patient who had a cystic mass in the distal thigh was evaluated, and osteolysis of the distal femur was detected. Polyethylene debris and reactive synovium were confirmed surgically and histologically, indicating a cause-effect relationship of polyethylene wear debris and failure of the total knee arthroplasty. Regular and long-term patient follow-up evaluation after total joint arthroplasty is essential for the detection of early evidence of occult polyethylene wear.

Circumferential toenail.

Congenital deformities occur in approximately 1% of all live births. The exact incidence of congenital foot deformities is unknown. The presence of a circumferential nail of the toe is a very rare deformity. In our review of the literature, we have encountered only two previously reported cases of circumferential toenails. In these cases the patients were siblings and also had circumferential fingernails. This report describes circumferential toenails without other hand or other congenital deformities.
