Rotated Salter-Harris type II Fracture of the phalanx
Journal of Orthopaedics and Traumatology, 2004Co-Authors: S. Stahl, A. Lerner, E. CalifAbstract:A Salter-Harris type II Fracture with a rotational deformity involving the proximal phalanx of the ring finger is described for the first time. An undetected rotational deformity accompanying a Salter- Harris Fracture compounds the Fracture’s healing since it does not remodel, resulting in a malrotated union. Therefore, a cautious clinical and radiographic assessment is required, and Fracture reduction should always be coupled with a correction of any evident rotational deformity.

Biomechanical study of 16-mm threaded, 32-mm threaded, and fully threaded SCFE screw fixation.
Journal of Pediatric Orthopaedics, 2020Co-Authors: Massimiliano Dragoni, Anneliese Dorothy Heiner, Simone Costa, Armando Gabrielli, Stuart L. WeinsteinAbstract:BACKGROUND: The initial goals of the treatment of slipped capital femoral epiphysis (SCFE) are to stabilize the epiphysis, prevent slip progression, and avoid complications. In situ fixation with a single screw is the most accepted procedure to provide an optimal fixation, but fixation failure and slip progression suggest that the procedure might be improved. The aim of the present study was to biomechanically compare partially threaded screws (16 mm and 32 mm) and fully threaded screws in an in vitro porcine model. METHODS: An unstable/acute SCFE was created in 18 skeletally immature porcine femurs through a type 1 Salter-Harris Fracture. Each femur was fixed using a 6.5-mm stainless-steel cannulated screw inserted through the physis under fluoroscopic guidance. The screw was either 16 mm threaded, 32 mm threaded, or fully threaded (n=6 each group). Each specimen was cyclically tested to failure fixation by anterior-to-posterior loading through the femoral head. RESULTS: No significant difference was detected between the Newton cycles to failure of the 3 screw-thread groups. The 16-mm threaded group had the highest frequency of femoral neck failure. CONCLUSIONS: The 16-mm threaded screws had the highest rate of neck failure and did not demonstrate additional fixation stability over the 32-mm threaded and fully threaded screws. As femoral neck Fracture is a rare but devastating complication in pediatric patients, clinical use of the 32-mm threaded and fully threaded screws may be indicated in SCFE fixation. CLINICAL RELEVANCE: The use of 32-mm or fully threaded screws is a valid SCFE treatment option. The increased number of threads in the metaphysis with these screws may confer additional biomechanical strength to the femoral neck.

Fracture-Separation of the Distal Femoral Epiphysis in a Premature Neonate
Journal of Ultrasound in Medicine, 2006Co-Authors: Ruth Eliahou, Naum Simanovsky, Nurith HillerAbstract:Fracture-separation of the epiphysis of the distal femur is a relatively rare injury in neonates but has been documented as a complication of difficult deliveries. Most of the cases reported previously were associated with vaginal delivery with the neonate in the breech presentation,' often due to high-birth-weight neonates. 2 Two cases following cesarean delivery were also reported. 3 The suggested mechanism for this type of injury is forced traction of the limb with acute angulation or twisting during delivery. 3 According to the Salter-Harris classification, 4 this type 1 injury is a Fracture through the physis, which causes separation between the epiphysis and metaphysis. The separation results in an increased width of the physis and frequently in displacement of the epiphysis. Here we describe a case of a premature neonate with a type 1 Salter-Harris Fracture of the distal femur following cesarean delivery, with gross posterolateral displacement of the epiphysis that was inapparent on plain radiography but accurately diagnosed with sonography.

Fracture dislocation of the pisiform bone in children: a case report and review of the literature.
Journal of Pediatric Orthopaedics B, 2015Co-Authors: Yannick Hurni, Cesare Fusetti, Vincenzo De RosaAbstract:: Simultaneous Fracture and dislocation of the pisiform is a rare condition, and only two cases have been reported in children. We retrospectively collected and reviewed clinical and radiographic data of a child with a type II Salter-Harris Fracture of the distal radius, associated with Fracture dislocation of the pisiform. In addition, we performed a systematic review of the literature available to date.
