6%), and rotational deformities (8.6%). Significant differences in patients' ages at the time of surgery were found between the group with and without complications (P=0.04), while sex, segment treated, preceding surgeries, length of FU, FD rod diameter, and length of bisphosphonate treatment were not significant. The Youden index showed that the risk of complications rose significantly in patients treated when younger than 5.5 years of age (P<0.05).
 
  This series displays the effectiveness and utility of FD rods at a median FU of over 4 years. Complication rates were comparable with the existing literature, with a notable increase in the number of side effects observed in younger patients (below the age of 5).

  Treatment of stable slipped capital femoral epiphysis (SCFE) most commonly involves in situ fixation with a standard cannulated screw, leading to physeal arrest. Recently, Pega Medical (Laval, Canada) introduced the free-gliding (FG) SCFE screw, which employs a growth-friendly, telescopic design. This study examines femoral neck growth and remodeling over the first 2 postoperative years in stable SCFE treated with FG versus standard screws.
 
  We retrospectively reviewed 32 hips (19 SCFE, 13 prophylactic) in 16 patients treated with FG screws for stable SCFE. We also reviewed 102 hips (63 SCFE, 19 prophylactic, 20 controls) in 55 patients treated with standard screws. Immediate postoperative radiographs were compared with 1- and 2-year follow-up images.
 
  For the overall study cohort, mean age at surgery was 12.2±1.9 years, with a mean slip angle of 26.9±18.0 degrees. In FG SCFE hips, the alpha angle remodeled 12.9±19.2 degrees in the first postoperative year (P=0.018) and articulotrochanteric distance decreased by 4.2±4.6 mm at 2 years (P=0.018). In standard SCFE hips, the alpha angle remodeled 4.3±11.3 degrees at 1 year (P=0.014), while articulotrochanteric distance decreased by 4.5±3.2 mm at 2 years (P<0.001). By 2 years, FG screws lengthened more in prophylactic (4.8±3.4 mm) than SCFE hips (1.7±1.8 mm, P=0.027).
 
  Greater remodeling of femoral neck cam deformity occurs when treating SCFE using an FG screw. Further research is required to measure the impact of this finding on femoroacetabular impingement and degenerative arthritis. In addition, FG screws allow ongoing growth of prophylactically treated hips, while standard screws promote coxa breva.

  The purpose of this study was to analyze the long-term results of humeral lengthening in achondroplastic patients and make suggestions on the most appropriate surgical technique to improve patient outcomes.
 
  Fifty-four humeral lengthening procedures performed in 27 achondroplastic patients were reviewed. Elongations were performed by means of callotasis with unilateral external fixation. Inclusion criteria were achondroplastic patients under 17 years without prior arm operations and minimum follow-up of 36 months.
 
  Fifty humeri in 25 patients (13 men and 12 women), aged between 9 and 17 years, met the inclusion criteria. Mean humeral lengthening was 8.82 cm (range 5 to 10.5 cm), which represented an elongation of 54.80% (range 46% to 63%) of the original length. The healing index was 0.91 months (range 0.72 to 1.4 mo) per centimeter gained. Shoulder and elbow range of motion and stability were preserved in 47 limbs. Noncomplicated cases consistently experienced a significant functional improvement in the ries.
  While supracondylar (SC) fractures are relatively common in children, the incidence of open injuries is believed to be only 1%. Two prior studies on open SC fractures in children reported an increased incidence of vascular injuries. The purposes of our study were to clarify the incidence, associated conditions, and current treatment for open SC fractures.
 
  The Pennsylvania Trauma Outcome Study database was queried. Subjects age 25 to 156 months old admitted to trauma centers between January 2000 and December 2015 with a SC fracture were included. Controls were those with closed fractures and the study group, those with open injuries. Study variables were age, sex, weight, injury severity score, length of stay (LOS), nerve injury, ipsilateral forearm fracture, compartment syndrome/fasciotomy, requirement for a vascular procedure. Other variables were mode of treatment, provisional reduction, repeat reduction, time interval between referring facility admission and operation, and time from emergency departmentrospective cohort study.
  Congenital vertical talus (CVT) is a rare congenital foot disorder. Approximately half of the affected children have associated neuromuscular syndromes which may further complicate the treatment.  https://www.selleckchem.com/products/sumatriptan.html  The traditional treatment involved extensive soft tissue and bony reconstructions. The minimally invasive method (Dobbs method/reverse Ponseti) has changed the treatment of CVT. There is significant variation of the reported outcome of this method in the current literature. In this study we report the outcome of this minimally invasive technique for treatment of CVT and compare the results of treatment in syndromic and idiopathic patients.
 
  Idiopathic and syndromic patients treated from CVT with minimally invasive method from 2006 till 2016 were included in this retrospective study. We reviewed the patients' notes, radiographs and collected parents reported outcome questionnaire (Roye score) in addition to clinical examination to comprehensively report the treatment outcome.
 
  A total of 21 patients 30 feet were included in this study. The average age of commencing treatment was 6 months (1 to 17 mo). The mean follow-up was 6.5 years (1 to 11 y). Correction of the deformities and abnormal angles were achieved in all feet. Five of the 17 syndromic feet had recurrence while no recurrence was reported in any if the 13 idiopathic feet. At the time of the index procedure no supplementary procedures were required. The average arc of motion for foot ankle dorsiflexion and plantar flexion was 30 degrees. Patients with idiopathic CVT had a mean the Roye score of 11 while syndromic patients had a mean score of 22.
 
  The minimally invasive method is a valuable option for treatment of CVT. Idiopathic patients had no recurrence and better functional scores compared syndromic patients. There was no requirement for supplementary procedures such as tibialis anterior transfer or anterolateral release at the time of the initial surgery.
