Comparative StudyTwo to twenty-year survivorship of the hip in 810 patients with operatively treated acetabular fractures.
The aims of the study were (1) to determine the cumulative two to twenty-year survivorship of the hip after open reduction and internal fixation of displaced acetabular fractures, (2) to identify factors predicting conversion to total hip arthroplasty or hip arthrodesis, and (3) to create a predictive model that calculates an individual's probability of early need for total hip arthroplasty or hip arthrodesis. ⋯ Open reduction and internal fixation of displaced acetabular fractures was able to successfully prevent the need for subsequent total hip arthroplasty within twenty years in 79% of the patients. The results represent benchmark comparative data for any future and past studies on the outcome of surgical fixation of acetabular fractures.

Comparative StudyPost-splinting radiographs of minimally displaced fractures: good medicine or medicolegal protection?
Many institutions perform radiographic documentation following splint application even when no manipulation had been performed. The purpose of this study was to evaluate the utility of post-splinting radiographs of acute non-displaced or minimally displaced fractures that did not undergo manipulation. Our hypothesis was that post-splinting radiographs do not demonstrate changes in fracture alignment or impact the management of the patient. ⋯ Post-splinting radiographs of non-displaced and minimally displaced fractures that do not undergo manipulation before or during immobilization are associated with longer ER waits, additional radiation exposure, and increased health-care costs without providing helpful information. While certain circumstances call for additional imaging, routine performance of post-splinting radiography of non-displaced or minimally displaced fractures should be discouraged.

Comparative StudyTalocalcaneal tarsal coalitions and the calcaneal lengthening osteotomy: the role of deformity correction.
Surgical resection of persistently painful talocalcaneal tarsal coalitions may not reliably relieve symptoms in patients with large coalitions associated with excessive hindfoot valgus deformity and subtalar posterior facet narrowing. Since 1991, calcaneal lengthening osteotomy, with or without coalition resection, has been used at our institution to relieve symptoms and to preserve motion at the talonavicular and calcaneocuboid joints. ⋯ It is generally accepted that resection is the treatment of choice for an intractably painful small talocalcaneal tarsal coalition that is associated with a wide, healthy posterior facet and minimal valgus deformity of the hindfoot. Although triple arthrodesis has been recommended for those who do not meet all three criteria, the present study suggests that an algorithmic treatment approach is justified. Treatment of the valgus deformity appears to be as important as that of the coalition. Calcaneal lengthening osteotomy with gastrocnemius or Achilles tendon lengthening is effective for correcting deformity and relieving pain in rigid flatfeet, just as it is in flexible flatfeet.

Comparative StudyThe association between preoperative spinal cord rotation and postoperative C5 nerve palsy.
C5 nerve palsy is a known complication of cervical spine surgery. The development and etiology of this complication are not completely understood. The purpose of the present study was to determine whether rotation of the cervical spinal cord predicts the development of a C5 palsy. ⋯ Our evidence suggests that spinal cord rotation is a strong and significant predictor of C5 palsy postoperatively. Patients can be classified into three types, with Type 1 representing mild rotation (0° to 5°), Type 2 representing moderate rotation (6° to 10°), and Type 3 representing severe rotation (≥ 11°). The rate of C5 palsy was zero of 159 in the Type-1 group, eight of thirteen in the Type-2 group, and four of four in the Type-3 group. This information may be valuable for surgeons and patients considering anterior surgery in the C4 to C6 levels.
