Bilateral posterior hip dislocations with femoral head fractures.

An unusual case of bilateral posterior fracture-dislocation of the hip (Pipkin Type IV) occurred in a 63-year-old man with Paget's disease of the pelvis. Other injuries included a displaced humeral shaft fracture and patellar ligament disruption. Bilateral cemented total hip arthroplasty was performed to avoid the need for prolonged immobilization. Postoperative low-dose irradiation was used because of the risk of heterotopic ossification.

Effect of a patella-stabilizing brace on lateral subluxation of the patella: assessment using kinematic MRI.

This study investigated the effect of a special patella brace on patients with lateral subluxation of the patella using kinematic magnetic resonance imaging (MRI). Fifteen patients were assessed with and without application of the brace (Shields Patella Stabilizing Brace, Hely & Weber, Santa Paula, Calif) using active-movement, against-resistance kinematic MRI of the patello-femoral joint. Kinematic MRI examinations were evaluated using previously described qualitative criteria to determine patello-femoral relationships. Eleven (73%) patellofemoral joints had improvement (55%) or correction (45%) of lateral subluxation of the patella. The brace failed to alter the position of the patella in four (27%) patients who had patella alta (two patients) or were extremely overweight (two patients). This study provided objective findings that application of the brace improved or corrected lateral subluxation of the patella in the majority of patients. This information has important implications for the conservative treatment of patients with this form of patellar malalignment.

Acute dislocation of the patella. Clinical, radiographic and operative findings in 64 consecutive cases.

The clinical, radiographic and operative findings in 64 consecutive acute dislocations of the patella were analyzed. Both patellofemoral joints were symptomless before dislocation in 58 patients. The sulcus angle of the femur on the affected side was larger than on the contralateral side in one half, and a fresh marginal patellar fracture was demonstrated in one third of the cases. The stability of the patella could not be reliably estimated in tangential views taken with the knee in 20 degrees flexion; especially false negative findings were numerous.

Mobile-bearing total knee prosthesis: a 5- to 9-year follow-up of the first 110 consecutive arthroplasties.

This study regards the total articulating cementless knee. This is a mobile-bearing knee, the tibial component of which consists of 2 parts: a highly conforming polyethylene insert freely rotating on a metal tray. Our case study relating to the implant of the first 110 knees operated on consecutively from 1991 to 1995 is reported, with an average follow-up of 6.3 years (range, 5-9 years). The average preoperative Knee Society Score was 78 points, and the average postoperative score was 156 points. The complications specifically related to the prosthetic components and which required revision surgery were 4: 2 cases of instability, 1 aseptic loosening of the tibial tray, and 1 traumatic dislocation of the tibial insert. A further 3 patients underwent reoperation for causes not strictly related to the implant: 2 because of intractable patellar pain and 1 because of periprosthetic ossifications that limited flexion. All of the complications were observed in patients operated on during the first 3 years of our experience, thus suggesting a definite learning curve with this prosthesis. No evidence of progressive radiographic periprosthetic osteolysis was recorded, and no relevant polyethylene wear was observed over time. Kaplan-Meier survival curves show the probability of survival to be 93.7% with revision surgery for any reason as an endpoint, and 96.3% with revision surgery for a mechanical reason as an endpoint. Certainty that mobile-bearing total knees are able to assure a longer life of the implant than the conventional models would require an evaluation of results over 15 to 20 years. However, in the meantime, these good preliminary results at least justify continuing the use of this type of prosthesis, which still awaits confirmation of the, as-yet-theoretical, advantage compared with fixed-bearing total knees.

Orthopaedic aspects of central core disease.

We studied the cases of fifteen patients who had central core disease, a non-progressive congenital myopathy that is usually inherited as an autosomal dominant trait. As infants, the patients had poor muscle tone and developmental delay, and as adolescents and adults, they had varying degrees of proximal muscle weakness and tended to use the Gower maneuver. The most common musculoskeletal problems were dislocation or subluxation of the hip, pes planus, and hypermobility of the joints. The most serious orthopaedic problems were in the hips: ten patients had a total of nine dislocations and six subluxations, nine being present at birth and six developing later. Only nine hips were stable after the initial treatment, and there was a propensity for hip-joint contractures. Scoliosis and patellar instability were also seen. Although patients who have central core disease have been reported to be at increased risk for malignant hyperthermia, this did not occur in our patients.

Deterioration of long-term clinical results after the Elmslie-Trillat procedure for dislocation of the patella.

We examined 39 patients (45 knees) who had undergone an Elmslie-Trillat procedure for recurrent or habitual dislocation of the patella with a follow-up of more than ten years. The mean age at the time of surgery was 18.4 years; the mean follow-up was 161 months (120 to 238). Using Fulkerson's functional knee score, 41 knees (91%) had an excellent or good result at a mean follow-up of 45 months, and this was maintained in 29 (64%) at the final review. The main cause of deterioration in the clinical results was the onset or worsening of patellofemoral joint pain, not patellar instability.

RAPADILINO syndrome with radial and patellar aplasia/hypoplasia as main manifestations.

A new malformation syndrome is described in a pair of sibs and 3 sporadic patients. The characteristic manifestations are radial aplasia or hypoplasia, absence of thumbs, absent or hypoplastic patellae, dislocations of joints, unusual face, cleft or highly arched palate, diarrhea in infancy, small stature, and normal intelligence. Recessive inheritance seems the most plausible cause. The acronym RAPADILINO syndrome is proposed.
