fixation selection in VFNFs.
 For the treatment of VFNFs, satisfactory reduction still remains the key surgical goal that prevents NU, while the incidence of AVN strongly depends on the initial displacement at the time of injury. Crossed screws were associated with a markedly lower FNS rate than parallel screws, which promote further randomised controlled trials to establish a guideline for optimal fixation selection in VFNFs.
  To evaluate the Magnetic resonance imaging (MRI) findings of patients with a clinical diagnosis of tennis leg and to explore the pathogenesis of tennis leg.
 
  A retrospective review of 58 (45 men, 13 women; age range, 7-81 years; mean age, 46.7 years) patients with a clinical diagnosis of tennis leg at our hospital during a 64-month period (May 2014 through Sep 2019) was conducted. All patients underwent MRI scan. Follow-up MRI was performed on 4 patients. Images findings, including integrity of the myotendinous junction and tendon of the gastrocnemius and soleus, and presence of fluid collection were analyzed.
 
  MRI revealed fluid collection between the medial head of the gastrocnemius and soleus in 44 cases (72.1%). In 25 cases (41.0%), the collected fluid spread to around the medial border of fascia cruris. Fifty-five cases (90.2%) had edema or disruption of the gastrocnemius, with most cases (n=55) showing edema or disruption of the medial head of the gastrocnemius at the myotendinous junction. Twenty-two (36.1%) cases had edema or disruption of the soleus, with most cases (n=17) showing edema or disruption of the soleus at the myotendinous junction. Plantaris tendon disruption was observed in 7 cases (11.5%). A thick area of reparative tissue at the distal myotendinous junction of the medial head of the gastrocnemius was observed in all 4 MRI patients followed up.
 
  Abnormalities of the medial head of the gastrocnemius at the myotendinous junction and tendon appear to be more common than those of the plantaris tendon. Reparative tissue at the distal myotendinous junction of the medial head of the gastrocnemius may be an important specific indication of chronic tennis leg injury.

  To investigate changes in the Garden index and other radiological parameters during reduction of femoral neck fractures.
 
  Ten healthy, human femoral specimens were obtained. A 2.0 mm diameter Kirschner wire was implanted in the centre of the femoral head. A perpendicular osteotomy was made in the middle of the femoral neck. The distal osteotomy surface was used as the angle of rotation (pronation and supination up to 90° at 10° intervals). Anterior-posterior and lateral view radiographs were taken at different angles. The Garden index and other relevant data were analysed using the picture archiving and communication system. Changes in the area of the femoral head fovea at different rotation angles were measured.
 
  There were no significant differences in the Garden index between 0-30° of pronation and supination (p>.05).  https://www.selleckchem.com/products/Irinotecan-Hcl-Trihydrate-Campto.html  For angles of 40-90°, there were statistically significant differences in the Garden index (p<.05). The area of femoral head fovea decreased with increasing pronation angle, and increased with increasing supination angle.
 
  The Garden index does not change significantly if the angle of fracture rotation is 0-30° (in either pronation or supination) during femoral neck fracture reduction. Therefore, it is impossible to judge the rotation of fracture in this range of angles. The Garden index can detect the rotation of fracture for rotation angles of 40-90° (in either pronation or supination). Changes in the area of the femoral head fovea can help determine the rotation of femoral neck fractures.

  8-10% of all Ulnar styloid fractures (USF) accompanying distal radius fractures are addressed surgically. The surgical fixation has to counteract forces of translation and rotation acting on the distal radioulnar joint (DRUJ). The different technics used were never compared biomechanically. Our study aims to compare the effects of different techniques of USF fixation on the forearm rotation and the dorsal-palmar (DP)-translation of the DRUJ.
 
  9 forearm specimens were mounted on a custom testing system. Load was applied for Pronosupination and DP-translation with the forearm placed in neutral position, pronation and supination. The positional change of the DRUJ was measured using a MicroScribe. Six different, sequential conditions were tested in the same specimen intact, USF and 4 repair techniques (2 K-wire, tension band wiring (TBW), headless compression screw, suture anchor).
 
  The USF significantly increased DP-translation and pronosupination compared to the intact condition. The DP-translation in neutral was reduced significantly with all four techniques compared to the USF condition. TBW and suture anchor also showed a significant difference to the K-wire fixation. In supination only the TBW and suture anchor significantly decreased DP-Translation. The rotational stability of the DRUJ was only restored by the K-wire fixation and the TBW.
 
  All four USF repair techniques partially restored translational stability; however, only K-wire fixation and TBW techniques restored rotational stability. TBW was biomechanically superior to the other techniques as it restored translational stability and rotational stability.

It is unknown if the overall burden of CCs associates with diminished symptom improvement after PCI for stable AP. We prospectively administered validated surveys assessing AP, dyspnea, and depression to patients undergoing PCI for stable AP at our institution, 2016-2018. The association of CC burden and symptoms at 30-days post-PCI was assessed via linear mixed effects models. Included individuals (N = 121; mean age 68 ± 10 years; response rate = 42%) were similar to non-included individuals. At baseline, greater CC burden was associated with worse dyspnea, depression, and physical limitations due to AP, but not AP frequency or quality of life. PCI was associated with small improvements in AP and dyspnea (p ≤ 0.001 for both), but not depression (p = 0.15). After multivariable adjustment, including for baseline symptoms, CC burden was associated with a greater improvement in AP physical limitations (p = 0.
