Large-diameter metal-on-metal articulations reportedly improve stability and wear in THAs. However, some reports suggest some patients have unexplained hip and early failures with these implants. Thus, the potential benefits may be offset by these concerns. However, the incidence of these problems is not clearly established. We therefore assessed hip pain, ...

While short-stem design is not a new concept, interest has surged with increasing utilization of less invasive techniques. Short stems are easier to insert through small incisions. Reliable long-term results including functional improvement, pain relief, and implant survival have been reported with standard tapered stems, but will a short taper ...

Dislocation after revision THA is a common complication. Large heads have the potential to decrease dislocation rate, but it is unclear whether they do so in revision THA. We therefore determined whether a large femoral head (36 and 40 mm) resulted in a decreased dislocation rate compared to a standard ...

The Bernese periacetabular osteotomy (PAO) is commonly used to surgically treat residual acetabular dysplasia. However, the degree to which function and radiographic deformity are corrected in patients with more severe deformities that have undergone previous reconstructive pelvic or femoral osteotomies is unclear. We evaluated hip pain and function, radiographic deformity ...

The indications for surgical techniques for treatment of recurrent hip dislocation after THA differ, and their rates of achievement of stability may not be similar. We (1) describe our indications for different approaches for recurrent dislocation, (2) outline an algorithmic approach to the management of recurrently dislocating hips after THA, ...

Current guidelines for management of critically ill stroke patients suggest that treatment in a neurocritical care unit (NCCU) and/or by a neurointensivist (NI) may be beneficial, but the contribution of each to outcome is unknown. The relative impact of a NCCU versus NI on short- and long-term outcomes in patients ...

Loss of the abductor portions of the gluteus medius and gluteus minimus muscles due to THA causes severe limp and often instability. To minimize the symptoms of limp and instability, the anterior ½ of the gluteus maximus was transferred to the greater trochanter and sutured under the vastus lateralis. A ...

Severe medial and/or superior defects encountered in revision THA are currently managed with jumbo (≥ 66 mm) acetabular components and modular augments, with reconstruction cages, or with the cup-cage technique. Preoperative planning can indicate when these techniques may not restore vertical and horizontal offset. Failure to restore offset can lead ...
