Fractures: Bone Repair01:27

Fractures: Bone Repair

6.5K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Flail Chest-II

858
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Acute Kidney Injury III: Clinical Manifestations

1.3K
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Summary
This summary is machine-generated.

Perilunate injuries, though severe, often result in good long-term wrist function and low pain. Re-operation or dominant hand injury negatively impacts outcomes for these rare wrist pathologies.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Wrist Biomechanics

Background:

  • Perilunate fracture-dislocations are severe wrist injuries from high-energy trauma, typically affecting young individuals.
  • This rare pathology is poorly understood due to limited studies with small sample sizes and short follow-up periods.

Purpose of the Study:

  • To evaluate functional, radiographic, and patient-reported outcomes following perilunate injuries.
  • To analyze trends in surgical practices for perilunate injuries over an extended period.

Main Methods:

  • Retrospective review of 123 patients undergoing open reduction and internal fixation for acute perilunate injury over 30 years.
  • Assessment of post-operative outcomes, including functional, patient-reported, and radiographic measures.
  • Statistical analysis (t-tests, ANOVA) to identify factors influencing outcomes.

Main Results:

  • Forty-seven patients with a 14-year mean follow-up showed good long-term outcomes.
  • Mean patient-rated wrist evaluation score was 24.2, with a visual analogue scale pain score of 2.4.
  • Patients achieved 56% of contralateral flexion-extension and 76% grip strength; re-operation and dominant hand injury correlated with worse results.

Conclusions:

  • Patients generally maintain high function and low pain levels long-term after perilunate injuries.
  • Further multi-center, prospective research is necessary to advance understanding and treatment strategies.
