Arthroscopic treatment of calcaneonavicular coalition in children.

Calcaneonavicular coalition is a common source of pain and more or less severe flat and stiff foot in children. Classically, treatment consists in resecting the coalition using a dorsolateral approach. Good quality resection and interposition can prevent recurrence.

Type IV-D thumb duplication: A new reconstruction method.

Introduction: In the Wassel type IV classification category, the thumb is duplicated from the metacarpophalangeal joint; this abnormality accounts for approximately 50% of the cases of thumb duplication. Type IV is divided into four subtypes in which the IV-D type, or convergent (9% of cases), is the most complex form because both thumbs are hypoplastic with a divergent metacarpophalangeal joint and a convergent interphalangeal joint. Reconstruction is prone to axis deformity and ligament laxity, whereas the Bilhaut-Cloquet technique's main pitfall is nail dystrophy.

[Arthroscopic anterior capsular release in medial contracture of the shoulder secondary to brachial plexus birth palsy. Preliminary results].

Purpose Of The Study: Retraction of the shoulder in internal rotation is observed in 25% of children with brachial plexus birth palsy (C5, C6 +/- C7). Early bone and joint deformities affecting the glenohumeral joint are the consequences. The stiff internal rotation requires surgical release which can involve the capsule and ligaments, muscles, or both.

[Reconstruction of long bone defects with a vascularized fibular graft after tumor resection in children and adolescents: thirteen cases with 50-month follow-up].

Purpose Of The Study: The vascularized fibular graft is a widely used technique for the reconstruction of long bone defects after tumor resection. Complications are not uncommon despite the presence of a good vascular supply. We report our experience with long bone reconstructions in children and adolescents after resection of primary malignant bone tumors.

Ulnar styloid fracture in children: a retrospective study of 46 cases.

Ulnar styloid fractures are frequently ignored in the treatment of wrist fractures in children. Forty-six untreated ulnar styloid fractures (40 tip and six base fractures) associated with radial injuries (45 patients) were retrospectively analysed. At the removal of the cast, we recorded that 80% had a nonunion of the styloid fracture.

Surgical treatment of radial neck fractures in children by intramedullary pinning.

Various surgical techniques have been used to treat displaced radial neck fractures in children, in order to reduce the displacement and to avoid complications. We report the results of a retrospective study performed on 20 patients with severely displaced radial neck fractures, who were treated with intramedullary pinning (Métaizeau technique). Mean age at injury was 9 years.

Integra artificial skin in the management of severe tissue defects, including bone exposure, in injured children.

A dermal substitute, Integra (Integra Neurosciences Implants SA, Sophia Antipolis, France) artificial skin, was used for wound management on three children with lower limb injuries in our institutions. In one case this biosynthetic material was applied directly to a bony surface (patella). This technique allows an early wound coverage and provides a satisfactory preparation for autograft.

Percutaneous Ethibloc injection in the treatment of primary aneurysmal bone cysts.

The effects of percutaneous Ethibloc (Ethicon/Johnson & Johnson, St-Stevens-Woluwe, Belgium) injection into primary aneurysmal bone cysts were analysed. Two patients with a venous drainage after injection of a medium contrast were excluded. Twelve patients underwent at least one percutaneous injection of Ethibloc.

[Recurrent aggressive chondroblastoma: two cases and a review of the literature].

Chondroblastoma is a rare benign bone tumor. Treatment currently consists of curettage and bone graft. Prognosis depends basically on a relatively high rate of recurrence, between 5 and 38%, sometimes with local seeding of soft tissues and joint space.

[Scarf osteotomy of hallux valgus in children and adolescents].

Purpose Of The Study: The aim of this study was to analyze the results of surgical treatment of hallux valgus using scarf osteotomy in children and adolescents.

Material And Method: Twelve children and adolescents (19 feet) operated on with scarf osteotomy were reviewed retrospectively with a mean follow-up of 15 months. Clinical and radiographic results were assessed.

Natural course of osteochondritis dissecans in children.

Results are reported from an absence of physiotherapic, orthopaedic, or surgical treatment in 31 cases of osteochondritis dissecans in 24 children. The mean age at diagnosis was 11 years and 4 months, and all the children were suffering from pain for an average of 3 months. None of these children were treated, except for instructions to discontinue involvement in sports activities until their pain had disappeared.

Kienböck's disease and multiple hereditary osteochondromata: a case report.

A case of bilateral forearm localization of multiple hereditary osteochondromata and unilateral Kienböck's disease is reported. Ulnar minus variance is frequent in both diseases. Carpal slip is often found in multiple hereditary osteochondromata.

Imaging evaluation of subluxation in Legg-Calvé-Perthes disease: magnetic resonance imaging compared with the plain radiograph.

The aim of the study was to evaluate the advantages of magnetic resonance imaging (MRI) in determining subluxation in Legg-Calvé-Perthes (LCPD) disease. Twenty-six patients with unilateral LCPD received 33 MRI and plain radiographs. For each patient, acetabulum head index (AHI) was measured on both hips (affected and unaffected) in a blinded fashion.
