Introduction. Sternoclavicular dislocations are well-known adult injuries. The same traumatism causes growth-plate fracture of the medial clavicle in children and young adults. At this location, the emergence of the secondary ossification center and its bony fusion are late. We report the results of 20 cases hospitalized in the Toulouse University Hospital Center that were treated surgically. Materials & Methods. 20 patients were treated between 1993 and 2007, 17 boys and 3 girls, 16 years old (6–20). The traumatism was always violent (rugby 75%). Two physeal fractures were anteriorly displaced, and 18 posteriorly. The follow-up is 64 month (8–174). Clinical, radiographic and therapeutic characteristics were assessed. The long-term results were analysed with: an algo-functional scale (Oxford shoulder score), the subjective Constant score, a functional disability scale (Shoulder simple test), a quality of life scale (DASH), and global indicators (SANE and global satisfaction). Results. all the patients were symptomatic before surgery: pains, oedema and partial functional impotence. Only 2 dysphagia, 1 dyspnea and 1 venous circulation alteration were observed. The first clinical and radiological examination, before CT scan, didn't diagnose the injury in 8 cases. The CT scan were realized for all the patients: it diagnosed the physeal fracture and showed 4 cases of vascular or respiratory compressions. There were 5 attempts of closed reduction, without success: all the patients were surgically-treated. The open reduction were completed by pinning (12 cases) or cerclage with absorbable suture (3 cases). Per-operatory findings lead to realize costo-clavicular repair plasties with the sub-clavicular muscle (3 cases) and/or capsular-ligamentous-perosteal selective plasties (13 cases). Two cases of broken Kirschner wires were noticed, without migration. Functional outcomes are largely good or excellent: STT 11,74/12 (10–12)–OSS 12,95/60 (12–19)–DASH 2,07/100 (0–17,6)–SANE 93,16% (60–100). Discussion and Conclusion. we present the largest case series in the literature. CT scanner is the essential element of the diagnostic process and may allow the distinction between true sterno-clavicular dislocation and displaced physeal fractures. This distinction is difficult at younger ages and is facilitated by the progression of ossification. Very good results were obtained, but classical pitfalls of treatment were found: instability after closed reduction, broken K-wires, recurrent anterior instability, inesthetic scars

Distal tibial physeal fractures are the second most common growth plate injury and the most common cause of growth arrest and deformity. This study assesses the accuracy of pre-operative planning for placement of the screws in these fractures using either standard radiographs or CT scans. We studied 62 consecutive physeal fractures over a period of four years. An outline of a single cut of the CT scan was used for each patient. An ideal position for the screw was determined as being perpendicular to and at the midpoint of the fracture. The difference in entry point and direction of the screw between the ideal and the observers’ assessments were compared using the paired Student’s t-test. There was a statistically significant improvement (p < 0.0001) in the accuracy of the point of insertion and the direction of the screw on the pre-operative plan when CT scans were used rather than plain radiographs. We would, therefore, recommend that CT scans are routinely used in the pre-operative assessment and treatment of distal tibial physeal fractures

Kirschner wires are commonly used in paediatric fractures, however, the requirement for removal and the possibility of pin site infection provides opportunity for the development of new techniques that eliminate these drawbacks. Bioabsorbable pins that remain in situ and allow definitive closure of skin at the time of insertion could provide such advantages. Three concurrent studies were performed to assess the viability of bioabsorbable pins across the growth plate. (1) An epidemiological study to identify Kirschner wire infection rates. (2) A mechanical assessment of a bioabsorbable pin compared to Kirschner wires in a simulated supracondylar fracture. (3) The insertion of the implants across the physis of sheep to assess effects of the bioabsorbable implant on the growth plate via macroscopic, pathohistological and micro-CT analysis. An infection rate of 8.4% was found, with a deep infection rate of 0.4%. Mechanically the pins demonstrated comparable resistance to extension forces (p=) but slightly inferior resistance to rotation (p=). The in vivo component showed that at 6 months: there was no leg length discrepancy (p=0.6), with micro-CT evidence of normal physeal growth without tethering, and comparable physeal width (p=0.3). These studies combine to suggest that bioabsorbable pins do not represent a threat to the growth plate and may be considered for physeal fracture fixation

Aims

This is a multicentre, prospective assessment of a proportion of the overall orthopaedic trauma caseload of the UK. It investigates theatre capacity, cancellations, and time to surgery in a group of hospitals that is representative of the wider population. It identifies barriers to effective practice and will inform system improvements.
