The removal of well-fixed porous ingrown femoral components.

It is now evident that some biologically well-fixed hip prostheses may require removal and/or revision much earlier than originally anticipated. The relatively atraumatic removal of porous ingrown but clinically unacceptable femoral components, while difficult, has become increasingly feasible because of accumulated clinical experience and advances in biomedical technology. Preoperative planning, adequate instrument armamentarium, and intraoperative patience are important keys to the successful removal of these implants.

Traumatic spondylolisthesis of the axis in a patient presenting with torticollis. A case report.

In a 34-year-old man with an acute traumatic spondylolisthesis (ATS) of the axis, the presenting physical sign was severe torticollis associated with reactive spasm of the right sternomastoid muscle. Computed axial tomography (CAT) was useful both in assessing the nature of ATS (which involved more displacement of the axis fracture and adjacent soft-tissues on the right side of the neck) and in ascertaining reduction, realignment, and healing. The reduction was sustained by halo-vest immobilization.

Obturator hip dislocation with ipsilateral fractures of the femoral head and femoral neck. A case report.

A 28-year-old female pedestrians, struck by an automobile, sustained an obturator hip dislocation with concomitant ipsilateral fractures of both the femoral head and femoral neck. This unusual hip injury seems not to have been previously reported. The femoral neck fracture was widely separated from the shaft, and unfortunately, a 6-mm deep indentation fracture involved the anterosuperior portion of the articulating surface of the femoral head. This complex injury was treated with a press-fit bipolar prosthesis.

Myositis ossificans following porous-ingrowth TK replacement.

Clinically significant myositis ossificans of the distal thigh following virginal porous-ingrowth total knee arthroplasty has not been previously reported. Associated and potentially contributing factors in this particular case were (1) the patient's preoperative hypertrophic gonarthrosis, (2) our difficulty in regulating her postoperative sodium warfarin (Coumadin) dosages, (3) the postoperative knee manipulation, and (4) possibly, the additional surgical exposure of this patient's distal femur required to use the femur-based alignment instrumentation. Postoperative heterotopic ossification developing in the vicinity of a porous-ingrowth total knee prosthesis can have clinical significance. Treatment of this problem by a means that does not interfere with early bone ingrowth into the implant is a practical concern that warrants investigation.

Atraumatic removal of a well-fixed porous ingrowth hip prosthesis.

The authors describe their experience in the removal of a firmly fixed porous coated femoral component of a bipolar hip prosthesis in a 36-year-old man on a methadone maintenance program. The uncemented prosthesis had been implanted for 15 months when the patient complained of hip pain. A methicillin-resistant Staphylococcus aureus infection was found in the hip joint. It was decided to remove the femoral component when the infection failed to respond to irrigation, debridement, and several weeks of intravenous antibiotic therapy and because the patient developed early signs of impending renal compromise and a deterioration of his general nutritional status. The technique for separating and removing the well-fixed porous ingrowth component from its intramedullary environment without damaging the cortical tube of the proximal femur is described.

Revision of failed hip surface replacement arthroplasties with a bipolar prosthesis. Three case reports with two- to three-year follow-up observations.

Three cases of an isolated femoral component failure of a hip surface replacement were treated by use of a press-fit bipolar prosthesis to articulate with the retained acetabular cup. At two to three years post-surgery (average, 31 months), these three conversions had good clinical function and maintained an acceptable radiographic appearance. While no optimal long-term solution currently exists for failed hip surface replacements in young adults, this rather straightforward surgical conversion may have a role to play in the interim management of some of these patients.

Stump fractures in lower extremity amputees.

A series of 23 above-knee and below-knee amputees who sustained an ipsilateral lower extremity fracture was qualitatively evaluated with respect to the nature of the injuries sustained, associated problems, and results of fracture treatment. The overall incidence of these fractures was 3% in a population of lower-extremity amputees. The stump fractures encountered were distal femur fractures and fractures about the hip. More than one fourth of these fractures had an initially missed or 'delayed' diagnosis. Most femur fractures were successfully treated by nonoperative means, and most of the hip fractures were treated operatively. The final rehabilitated status of the dysvascular amputees was the poorest: one half of those who were previous household ambulators remained wheelchair confined postinjury.

Ipsilateral carpal, metacarpal, and ankle fractures resulting from an attempted basketball slam-dunk. A case report.

A 23-year-old male recreational basketball player sustained an open ankle fracture and ipsilateral carpal and metacarpal fractures as a result of a fall while attempting a slam-dunk. The wrist and hand fractures were treated nonoperatively. The open ankle fracture required irrigation, debridement, and open reduction/internal fixation. In addition to the prerequisite leaping ability, long-term success in "playing above the rim" requires experience, exceptional physical agility, and the mental discipline to anticipate and avoid slam-dunk opportunities with high risk for personal injury.
