Ulnar dimelia - a review of 24 cases.

Ulnar dimelia is a very rare unilateral congenital upper limb anomaly (CULA) affecting the whole extremity. Treatment remains difficult because of the complexity and multi-level involvement. Twenty-four cases with duplicated ulna, absent radius and polydactyly from seven European centres were reviewed according to a structured list of parameters.

State of the art review: The pathogenesis and management of Madelung deformity.

Madelung deformity remains a fascinating yet unresolved challenge. There is an increasing awareness for early diagnosis by healthcare providers with improvement in diagnostic modalities, however, the exact mechanisms for the development of the deformity have still to be clarified. While some corrective procedures have been described to effectively address an established deformity, the existing literature lacks clear and evidence-based treatment guidelines on how to proceed in daily practice.

Satisfactory thumb metacarpophalangeal joint stability after ligament reconstruction with flexor digitorum superficialis in children with radial longitudinal deficiency.

We investigated thumb joint stability and patient-reported and functional outcomes a minimum of 1 year after flexor digitorum superficialis opponensplasty and ligament reconstruction in 23 thumbs of 20 consecutive children with radial longitudinal deficiency. In total, 15 thumbs had preoperative multidirectional instability in the metacarpophalangeal joint. We reconstructed 22 ulnar and 16 radial collateral ligaments.

Validity and Reliability of the Thumb Grasp and Pinch Assessment for Children After Reconstruction of Congenital Hypoplastic Thumbs.

Purpose: The Thumb Grasp and Pinch Assessment (T-GAP) is a new instrument for evaluating thumb use in children with congenital hypoplastic thumbs. The assessors video-record the children while they perform nine specific activities and score their grasp types using T-GAP. A high T-GAP score indicates more mature grasp patterns.

Biopsies from the Distal Radius after Implantation of Calcium Phosphate Cement.

Calcium Phosphate (CaP) bone cement is gradually replaced by new bone when used as a gap-filler. Details of the re-modelling process are still unclear. Uncertainty is also present as to the possible release of cement particles during the resorption phase causing local soft tissue reactions.

Calcium phosphate bone cement and metaphyseal -corrective osteotomies in the upper extremity: long-term follow-up of 10 children.

Background And Purpose: The evaluation of metaphyseal angular deformities in children includes indication and timing for corrective osteotomy, and possible need for several operations during growth. Gap-fillers are usually autologous bone grafts, which might cause donor site problems. Calcium phosphate (CaP) bone cement may be a possible alternative.

Outcome After Pollicization for Congenital Thumb Deficiency: A Cohort Study of Cases in a Single Unit, 1987 to 2016.

Purpose: To investigate the functional and aesthetic outcomes in a cohort with pollicizations performed due to congenital anomalies in our hospital.

Methods: From 1987 to 2016, we performed pollicizations in 32 hands of children aged 1 to 8 years (median, 2 years). We followed-up on 31 of the hands from 1 to 31 years (median, 10 years) after the procedure.

Satisfying Clinical and Functional Results in 12 Apert Children Treated With Soft Tissue Distractor.

Background: The complex syndactyly in Apert syndrome hands is challenging to operate. The synostosis and tightness of skin between third and fourth digits lead to severe coverage problems during ray release. A soft tissue distractor can simplify the release with the aim to keep all 10 fingers.

CaP cement is equivalent to iliac bone graft in filling of large metaphyseal defects: 2 year prospective randomised study on distal radius osteotomies.

The purpose of this prospective randomised study was to compare the clinical and radiological outcomes of injectable CaP bone cement with corticocancellous bone graft used to fill voids after corrective opening wedge osteotomies in the distal radius. 17 women/3 men, median age 56 (51.3; 61.

Effect of soft-tissue attachment on tibial fracture healing in rats.

Purpose: To compare tibial fracture healing in rats with or without soft-tissue attachment.

Methods: The left tibias of 30 Wistar rats were osteotomised and equally randomised into 3 groups. In the avascular segmental fracture group, an 8-mm bone segment were first removed and then immediately put back.

Calcium phosphate bone cement: a possible alternative to autologous bone graft. A radiological and biomechanical comparison in rat tibial bone.

Background: Donor site morbidity is a problem after autologous bone transplantation. An injectable CaP bone cement indicates properties similar to bone.

Materials And Methods: Double osteotomies on rat tibias were performed.
