Aim: To evaluate long-term outcomes of spinal neurostimulation (SNS) in patients with critical lower limb ischemia (CLI).
Material And Methods: Long-term outcomes of SNS were assessed in 52 CLI patients. Changes of clinical status were considered by using of Rutherford R.B. et al. scale. Before and in 12 months after SNS percutaneous oxygen partial pressure (TO, mm Hg) was measured at the affected lower limb at rest and in orthostatic test. Ankle-brachial index (ABI) was also determined.
Results: SNS improved clinical status in most cases through following effects: 1) reduced pain syndrome and increased motor activity; 2) skin ulcers healing due to increased TO and improved functional state of microcirculation. No augmentation of TO during orthostatic test at TO <10 mm Hg was associated with negative clinical dynamics after SNS (OR 3.2, CI 2.2-54.1, p=0.002). Coronary artery disease with supra-aortic vessels lesion was associated with reduced ABI after SNS (OR 2.1, CI 1.4-3.8, p=0.001).

Few studies have explored hip morphology and cartilage composition in female athletes or the impact of asymmetric repetitive loading, such as occurs during softball pitching. The current cross-sectional study assessed bilateral bony hip morphology on computed tomography imaging in collegiate-level softball pitchers ('Pitch1', n = 25) and cross-country runners ('Run', n = 13). Magnetic resonance imaging was used to assess cartilage relaxation times in a second cohort of pitchers ('Pitch2', n = 10) and non-athletic controls ('Con', n = 4).

Deep vein thrombosis (DVT) in patients undergoing endoscopic endonasal surgery remains underexplored, despite its potential impact on postoperative recovery. This study aimed to develop and validate a predictive nomogram for assessing the risk of lower-limb DVT in such patients without chemoprophylaxis. A retrospective analysis was conducted on 935 patients with postoperative lower-limb vein ultrasonography.

Objective: Chronic limb-threatening ischemia (CLTI) requires revascularization whenever it is possible. The great saphenous vein represents the surgical conduit of choice. However, it is not always available, in particular in multi-operated patients.

Background: Precise and accurate glenoid preparation is important for the success of shoulder arthroplasty. Despite advancements in preoperative planning software and enabling technologies, most surgeons execute the procedure manually. Patient-specific instrumentation (PSI) facilitates accurate glenoid guide pin placement for cannulated reaming; however, few commercially available systems offer depth of reaming control.

Background: This study investigated the influence of surgical alignment techniques on knee joint biomechanics during stair negotiation tasks. Our hypothesis was that a more personalized joint alignment would result in reduced medial knee loading biomechanics to negotiate the stairs.
Methods: There were 28 adults (14 mechanical alignments [MA], 14 kinematic alignment [KA]) who underwent total knee arthroplasty (TKA) at least one year post-operatively and performed five stair ascent and descent trials at their preferred velocities.
