Article Synopsis
- The study investigates the relationship between syndesmotic injuries and deltoid ligament (DL) injuries, aiming to evaluate their frequency and severity in patients undergoing surgery for unstable syndesmotic injuries.
- MRI assessments were performed on 37 patients to classify the severity of injuries, revealing an average severity of 2.6 for the syndesmotic complex and 1.6 for the DL injuries.
- Results indicated that unstable syndesmotic injuries can occur with or without DL injuries, highlighting significant variability in injury severity between these two structures.
Purpose: The aim of this systematic review and meta-analysis was to compare re-rupture rates, complication rates, functional outcomes, as well as return to work (RTW)/sport (RTS) among different rehabilitation protocols following operative treatment of acute Achilles tendon ruptures.
Methods: Systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Five databases were searched for randomized controlled trials (RCTs) comparing at least two rehabilitation protocols following surgical repair of acute Achilles tendon ruptures.
Background: Up to date there is no intramedullary, biodegradable osteosynthesis commercially available to treat non-comminuted midshaft fractures of small hollow bones applying not only a stable osteosynthesis but an additional axial compression to the fracture site.
Objective And Methods: Therefore we (1) designed different implant profiles and simulated the inner tension/volume using CAD. (2) Thereafter we manufactured a prototype with the best volume/tension-ratio using 70:30 poly-(L-lactide-co-D, L-lactide) (PLLA/PDLLA) and poly-ε-caprolactone (PCL) by injection moulding.

Objective: Arthroscopic tibiotalocalcaneal arthrodesis (TTCA) aims at reconstructing a pain-free, orthograde, and functional limb with reduced invasiveness and lower complication rates compared to open arthrodesis.
Indications: Combined osteoarthritis of the ankle and subtalar joint or hindfoot malalignment.
Contraindications: Osteomyelitis/deep soft tissue infections, talus necrosis, severe deformity of hindfoot or distal tibia, pronounced boney defect, indication for combined total ankle replacement and subtalar fusion.
Background: Chondral and osteochondral lesions are being detected with increasing frequency. For large-diameter lesions, cell-based treatment modalities are speculated to result in the best possible outcome.
Purpose: To prospectively evaluate the 2-year clinical and radiological results after the treatment of chondral and osteochondral knee joint lesions by a single-step autologous minced cartilage procedure.
Background: Open tibiotalocalcaneal arthrodesis (TTCA) is associated to high complication rates, which led to the development of arthroscopic techniques. Aim was to compare complication rates of open to arthroscopic TTCA in high-risk patients.
Methods: Single-center, retrospective case-control study.
Background: Distal radius fractures (DRF) are often referred to as osteoporosis indicator fractures as their incidence increases from age 45. In the group of young adults, distal radius fractures normally result from high-energy trauma. Wrist fractures in young patients without adequate trauma thus raise suspicion of a pathologic fracture.

Hypothesis: Skiers can resume low-impact sports activity after internal fixation of tibial plateau fractures.
