AR results in a significantly smaller deficit at 10° of plantarflexion compared to CR (13.9 vs. 29.9%, p < 0.05). This reflects into the functional performance during different modalities (static vs. dynamic) in this novel method of heel-rise testing.
 
  In summary, there are persisting functional deficits at > 3years following Achilles tendon repair which range from strength deficits to specific impairmentsof functional performancee.g. during heel rise. Anatomical reconstruction is associated with an improved functional performance potentially due to a more symmetric strength during end-range plantarflexion which transfers into a higher satisfaction during athletic activities.
 
  III, retrospective cohort study.
 III, retrospective cohort study.
  The purpose of this study was to evaluate the demographics, complications and prodromal symptoms (any pain or unpleasant sensation in the area distal biceps tendon preceding the injury) of distal biceps tendon tears (DBTTs) of patients treated with primary repair or Achilles allograft reconstruction.
 
  228 consecutive DBTTs in 226 patients from a single centre were evaluated. The demographic data, prodromal symptoms and postoperative adverse events were documented.
 
  There were 225 males and 1 female patient. The age distribution showed a bimodal pattern in the whole cohort, but once the 48 (20%) elite athletes were excluded, the age was normally distributed, peaking in the 5
  decade.  https://www.selleckchem.com/products/bms-927711.html  Direct repairs were performed in 184 cases and reconstruction with Achilles tendon allograft in 45 cases. An adverse event was observed in 34 (19%) patients who underwent direct repair and in 3 (7%) cases with graft reconstruction, corresponding to RR of 0.32 (95% CI 0.1-0.96, p = 0.04). Adjusting with the potential confounders (age, occupation and smoking), the OR was 0.35; 95% CI 0.09-1.3, p = 0.11). Adverse events included 28 (12.3% of all adverse events) lateral antebrachial cutaneous nerve (LABCN) neurapraxias, 5 (2.1%) other neurapraxias, 6 (2.6%) heterotopic ossifications and 1 (0.4%) re-rupture. Twenty-three (10%) patients reported prodromal symptoms before the tear.
 
  DBTT is a condition that affects men predominantly. The observed bimodal incidence distribution was related to elite athletes, but in the normal population the peak occurs at the age typical to tendinopathies. LABCN neurapraxia was the most common adverse event, and graft use does not seem to predispose to adverse events.

  The optimal treatment strategy for the surgical management of femur fractures and non-unions remains unknown. The aim of this study is to assess union rates, complications and outcome after femoral double plating. Treatment of shaft, distal, periprosthetic fractures and pathological proximal femur fractures as well as femoral non-unions with double plating were evaluated.
 
  A systematic review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement was conducted. Published literature reporting on the treatment and clinical outcome of femoral fractures and non-unions with double plating was identified. In total, 24 studies with 436 cases of double plating, 64 cases of single plating, 84 cases of intramedullary nailing (IM), and 1 interfragmentary screw treatment met the inclusion criteria of this systematic review. The evaluated literature was published between 1991 and 2020.
 
  Double plating of femoral fractures achieved high healing rates and few complications were reported. It displayed significantly less intraoperative haemorrhage, shorter surgery time reduced risk of malunion in polytraumatised patients when compared to IM. Fracture healing rate of double-plating distal femoral fractures was 88.0%. However, there were no significant differences regarding fracture healing, complication or functional outcome when compared to single plating. Treatment of periprosthetic fractures with double plating displayed high healing rates (88.5%). Double plating of non-unions achieved excellent osseous union rates (98.5%).
 
  The literature provides evidence for superior outcomes when using double plating in distal femoral fractures, periprosthetic fractures and femoral non-unions. Some evidence suggests that the use of double plating of femoral fractures in polytraumatised patients may be beneficial over other types of fracture fixation.

  There is a growing number of publications highlighting sarcopenia and myosteatosis as poor prognosic factors for treatment results in oncological patients. The decrease in the cross-sectional area (CSA) of the multifidus muscle and muscle steatosis is associated with lumbar disc herniation and low back/limb pain. Nevertheless, no studies have analyzed the influence of the above parameters on patient satisfaction, pain decrease and return to daily activities. The aim of the study was to verify whether decreased preoperative CSA of the paraspinal and psoas major muscles and their fatty degeneration (myosteatosis) may influence the outcome of surgical treatment of lumbar disc disease (LDD).
 
  One hundred and one patients with LDD undergoing open microdiscectomy were enrolled in the analysis. Relative cross-sectional areas (rCSA) of the paraspinal and psoas major muscles as well as their fatty degeneration were measured. Patients were assessed according to the validated Polish versions of the EURO EQ-5D, Core Oe of fatty degeneration of the paraspinal muscles correlates with better outcomes 1 and 6 months after microdiscectomy.
  The purpose of the study was to compare treatment outcomes after short or long cephalomedullary nailing for intertrochanteric femur fractures.
 
  A systematic review of perioperative outcomes after short or long cephalomedullary nailing for intertrochanteric femur fractures was performed. The following databases were used using the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, PubMed (1980-2019), and MEDLINE (1980-2019). The queries were performed in June 2019.
 
  The following search term query was used "Intramedullary Nail AND Intertrochanteric Fracture OR "Long OR Short Nail AND intertrochanteric Fracture." Studies were excluded if they were "single-arm" studies (i.e., reporting on either long or short CMN but not both), or did not report at least one of the outcomes being meta-analyzed. Furthermore, cadaveric studies, animal studies, basic science articles, editorial articles, surveys and studies were excluded.
 
  Two investigators independently reviewed abstracts from all identified articles.
