Hemicallotasis for correction of varus deformity of the proximal tibia using a unilateral external fixator.

Background: Gradual correction of varus deformity of the proximal tibia is generally accepted and produces good results. However, most studies have used circular external fixators, which are complex and cause patient discomfort. This study was undertaken to determine the efficacy of hemicallotasis with a unilateral external fixator for correction of varus deformity of the proximal tibia.

Bone transport over an intramedullary nail for reconstruction of long bone defects in tibia.

Background: Although long bone defects may be treated by callus distraction, frequent complications arise from the long duration of external fixation. To reduce such complications, bone transport over an intramedullary nail (BTON) has been done for tibial bone defect.

Methods: In 12 patients (mean age, 46.

Early failure of hemispheric hydroxyapatite-coated acetabular cups.

Unlabelled: Total hip arthroplasties with hydroxyapatite coatings have shown encouraging results after early-term followup. We presumed hydroxyapatite-coating on a smooth hemispheric press-fit acetabular cup would enhance bone osseointegration and maintain stability of cup after midterm (minimum 5-year) followup. Sixty-three patients had 70 consecutive total hip arthroplasties.

Total hip arthroplasty with the use of nonmodular cementless acetabular component.

Sixty-seven hips in 63 patients who underwent total hip arthroplasties with the use of the nonmodular cementless acetabular component and alumina-on-polyethylene bearing surface were available for complete clinical and radiographic review at a mean follow-up period of 7 (range 5-9) years. The mean age was 59 years (range 34-75) years. The mean preoperative Harris hip score of 50 points improved to 93 points at final follow-up.

Percutaneous plate stabilization of proximal tibial fractures.

Background: Despite various treatment methods, proximal tibial fractures are common injuries associated with poor outcomes and high rates of complications. To improve this, a percutaneous plating technique was performed to treat proximal tibial fractures.

Methods: Twenty-four proximal tibial fractures (17 proximal fractures [AO 41] and 7 proximal shaft fractures [AO 42]) were treated using percutaneous plating with either or both sides without bone graft.

Functional outcome after operative treatment of eight type III coronoid process fractures.

Background: There have been few reports about surgical outcomes of coronoid process fractures. Eight cases of clinical results of type III coronoid process fractures were reviewed.

Methods: Eight patients with coronoid type III fracture were retrospectively reviewed.

Vascularized compared with nonvascularized fibular grafts for large osteonecrotic lesions of the femoral head.

Background: Many authors have reported good results with the use of vascularized fibular grafts to treat large osteonecrotic lesions of the femoral head. To our knowledge, there have been no prospective case-controlled studies comparing the effectiveness of vascularized fibular grafting with that of nonvascularized fibular grafting for the prevention of progression and collapse of the lesion.

Methods: Nineteen patients (twenty-three hips) with a large osteonecrotic lesion of the femoral head (Stage IIC in ten hips, Stage IIIC in two, and Stage IVC in eleven, according to the classification system of Steinberg et al.

Femoral lengthening over an intramedullary nail using the external fixator: risk of infection and knee problems in 22 patients with a follow-up of 2 years or more.

Background: The time for femoral lengthening is shortened if external fixation is combined with intramedullary nailing. However, several complications have been reported with this procedure.

Patients And Methods: We retrospectively reviewed the outcome of femoral lengthening performed over an intramedullary nail using external fixation in 22 patients.

An arthroscopic analysis of lateral meniscal variants and a comparison with MRI findings.

We reviewed 164 consecutive cases (158 patients) of arthroscopic examinations for lateral meniscal variants during the last 10 years. We classified lateral meniscal variants into four types by arthroscopic appearance, into six tear patterns by modifying O'Connor's classification, and compared magnetic resonance images (MRI) with arthroscopic findings. Regarding the four types, 131 cases were complete, 25 cases were incomplete, 4 cases were Wrisberg, and 4 cases were ring-shaped meniscus.

Uncemented Harris-Galante total hip arthroplasty in patients with osteonecrosis of the femoral head. A 10-16-year follow-up study.

Background: There have only been a few reports regarding the long-term results of uncemented THAs in patients with osteonecrosis.

Patients And Methods: We evaluated the long-term results of 65 consecutive uncemented total hip arthroplasties (Harris-Galante type I prostheses) in 54 men (59 hips) and 5 women (6 hips) with osteonecrosis of the femoral head. The mean age was 53 (33-64) years.

Minimally invasive percutaneous plating of distal femoral fractures using the dynamic condylar screw.

Background: In distal femoral fractures, conventional open reduction and internal fixation causes complications because of excessive soft-tissue stripping. To prevent this, minimally invasive percutaneous plating was performed in distal femoral fractures.

Methods: Sixteen supracondylar or intercondylar femoral fractures were treated by minimally invasive percutaneous plating with the dynamic condylar screw without bone graft.

Cementless Metasul metal-on-metal total hip arthroplasty in patients less than fifty years old.

Background: Durable results of total hip arthroplasty have been difficult to achieve in young patients. We reviewed the intermediate-term clinical and radiographic results in a series of active, higher-demand patients who were less than fifty years old when they underwent cementless total hip arthroplasty with the use of the Metasul metal-on-metal articulation.

Methods: Seventy total hip arthroplasties were performed in sixty-two patients who were younger than fifty years of age (average age, thirty-seven years).

Treatment of femoral shaft fractures in young children: comparison between conservative treatment and retrograde flexible nailing.

Outcomes of pediatric femoral fractures treated with traction followed by cast (conservative treatment) were compared with flexible nailing treatment. Fifty-one femoral fractures (24 conservative, 27 nail) from 46 patients were studied retrospectively. Four cases of angular deformities greater than 10 degree were observed from the conservative treatment and none from the nailing group.

Recurrence of synovial chondromatosis of the glenohumeral joint after arthroscopic treatment.

A case of primary synovial chondromatosis of the shoulder in a 15-year-old girl is presented. Plain radiographs revealed findings characteristic of synovial chondromatosis. The patient was treated by arthroscopic loose body removal and arthroscopic partial synovectomy of the glenohumeral joint.

Minimal invasive percutaneous Herbert screw fixation in acute unstable scaphoid fracture.

The purpose of this study is to document the percutaneous Herbert screw fixation technique with free-hand method to stabilise acute unstable scaphoid fractures and evaluated the clinical results. Thirteen patients with less than 14 day-old fractures were fixed by percutaneous Herbert screw and reviewed retrospectively for a minimum of 24 months (average, 37 months). All were men with an average age of 22 years.

Percutaneous plating for unstable tibial fractures.

Twenty-four unstable tibial fractures were stabilized with a narrow limited contact-dynamic compression plate inserted using a percutaneous plating technique under fluoroscopic guidance. The major indication for this technique was a tibial fracture for which intramedullary nailing would be difficult. There were 16 proximal or distal metaphyseal fractures and 5 segmental fractures in adults and 3 mid-shaft fractures in adolescents who still had an open physis.

Completely displaced supracondylar humerus fractures in children: results of open reduction versus closed reduction.

This retrospective study was performed to understand the clinical results after closed reduction and open reduction in 35 children (mean age 6.4 years) with completely displaced supracondylar fractures of the distal humerus between 1996 and 2000. Closed reduction (21 cases) was attempted, with open reduction (14 cases) indicated in irreducible cases with or without severe swelling.

Distal tibia metaphyseal fractures treated by percutaneous plate osteosynthesis.

Twenty-one patients with fractures of the distal tibial metaphysis, some with minimal displacement in the ankle, were treated by percutaneous plate osteosynthesis with a narrow limited contact-dynamic compression plate. Using the classification by the Arbeitsgemeinschaft für Osteosynthesefragen and Orthopaedic Trauma Association, 17 fractures had no articular involvement, whereas four included intraarticular extension. At final followup (mean, 20 months), all the fractures healed without second procedures and the mean union time was 15.
