Management of neglected Blount disease using double corrective tibia osteotomy and medial plateau elevation.

PURPOSE: A double osteotomy for correcting tibial deformity in combination with medial plateau elevation is recommended for the management of neglected Blount disease cases. We report our clinical experience with the application of this surgical technique and describe the long-term follow-up of the patients who were operated on. METHODS: During a 10-year period, eight children (8 boys) with mean age of 12 years (range 9-14 years) underwent surgery (9 operations) due to neglected infantile tibia vara. All patients suffered from stage V or VI Blount disease according to the Langenskiold and Riska classification. Two simultaneous combined osteotomies were performed for medial plateau elevation and for correction of the tibial deformity. The correction was immediate using K-wires for stabilization and a long-leg cast for immobilization. The mean duration of follow-up was 10 years (range 5-15 years), and the evaluations were based on clinical and radiological criteria. RESULTS: At the latest follow-up, there was no observable knee flexion or extension restriction and no signs of instability or lateral thrust. All patients had returned to a higher activity level. Leg-lengthening surgery was performed in one child, but the length discrepancy was already present before the double osteotomy was performed. No other complications were noticed. All the angles measured on X-rays had been corrected, and this correction was retained until the latest follow-up. CONCLUSIONS: This method results in very good outcomes in patients who suffer from Blount disease of stage V or greater. With this technique, the tibial deformity is corrected, the articular surface is restored, and future recurrence is prevented.

Spontaneous correction of partial physeal arrest: report of a case and review of the literature.

This study describes the rare phenomenon of partial physeal arrest spontaneous correction. It concerns a case of a 3.5-year-old girl who suffered from a Salter-Harris IV fracture of the distal tibial epiphysis, which was managed conservatively. After fracture healing an osseous bridge was formed at the medial part of the physis, leading to a varus deformity. The parents refused the operation, but 6 years later, both the ankle's deformity and the shortening of the extremity had been spontaneously corrected. It seems that the growth potential of the physis healthy portion is able to break the already transformed osseous bridge.

Traumatic hand amputations among children in Greece: epidemiology and prevention potential.

BACKGROUND: Traumatic hand and finger amputations frequently lead to permanent disability. OBJECTIVE: To investigate their epidemiological characteristics and estimate the prevention potential among children 0-14 years old, through a cross-sectional survey. METHODS: Nationwide extrapolations were produced based on data recorded between 1996 and 2004 in the Greek Emergency Department Injury Surveillance System and existing sample weights. Incident and injury related characteristics were analysed to identify preventable causes. RESULTS: Among 197,417 paediatric injuries, 28,225(14%) involved the hand and fingers resulting in 236 amputations (∼1% of hand injuries). The annual probability to seek emergency department care for a hand injury was 3%. The estimated incidence rate (IR) of hand amputations was 19.7/100,000 person-years. Over 50% concerned children 0-4 years old (male:female=2:1), peaking at 12-24 months. Male preschoolers suffered the highest IR (38.7/100,000). Migrant children were overrepresented among amputees. Of all amputations, 64% occurred in the house/garden and 14% in day-care/school/sports activities, usually between 08:00 and 16:00 (61%). Doors were the product most commonly involved (55% overall; 72% in day-care/school/gym) followed by furniture/appliances (15%) and machinery/tools (7%). Crushing was the commonest mechanism. Inadequate supervision and preventive measures were also frequently reported. 5% of the amputees were referred to specialised units for replantation/reconstructive surgery. CONCLUSIONS: The majority of paediatric hand and finger amputations could be prevented in Greece, particularly among preschoolers, by a single product modification, namely door closure systems, coupled with improved supervision. Paediatricians should incorporate this advice into their routine child-safety counselling. This country-specific profile supports the need for maintaining similar databases as an indispensable tool for assisting decision-making and preventing disabling and costly injuries.

Pediatric fractures of the foot and ankle.

Distal tibial physeal injuries are common in children, accounting for 10% to 40% of all injuries to skeletally immature patients. This article describes the classification, treatment, and complications of distal tibial fractures, fractures of the talus and calcaneus, midfoot and tarsometatarsal injuries, metatarsal fractures, and fractures of the phalanges in children.

Painful rib hump: a new clinical sign for detecting intraspinal rib displacement in scoliosis due to neurofibromatosis.

BACKGROUND: Spinal cord compression and associate neurological impairment is rare in patients with scoliosis and neurofibromatosis. Common reasons are vertebral subluxation, dislocation, angulation and tumorous lesions around the spinal canal. Only twelve cases of intraspinal rib dislocation have been reported in the literature. The aim of this report is to present a case of rib penetration through neural foramen at the apex of a scoliotic curve in neurofibromatosis and to introduce a new clinical sign for its detection. METHODS: A 13-year-old girl was evaluated for progressive left thoracic kyphoscoliotic curve due to a type I neurofibromatosis. Clinical examination revealed multiple large thoracic and abdominal "cafe-au-lait" spots, neurological impairment of the lower limbs and the presence of a thoracic gibbous that was painful to pressure at the level of the left eighth rib (Painful Rib Hump). CT-scan showed detachment and translocation of the cephalic end of the left eighth rib into the adjacent enlarged neural foramen. The M.R.I. examination of the spine showed neither cord abnormality nor neurogenic tumor. RESULTS: The patient underwent resection of the intraspinal mobile eighth rib head and posterior spinal instrumentation and was neurologically fully recovered six months postoperatively. CONCLUSION: Spine surgeons should be aware of intraspinal rib displacement in scoliotic curves in neurofibromatosis. Painful rib hump is a valuable diagnostic tool for this rare clinical entity.
