Fractures: Bone Repair

4.9K
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

511
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.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Trauma Surgery

Background:

  • Bennett fractures are unstable thumb base fractures often leading to complications like malunion, nonunion, and arthritis if not treated promptly.
  • Neglected Bennett fracture nonunion presents a significant clinical challenge, impacting thumb function and potentially leading to long-term disability.

Purpose of the Study:

  • To present a novel treatment approach for neglected Bennett fracture nonunion using suture button suspension and small fragment excision.
  • To evaluate the efficacy and outcomes of this technique in two case studies.

Main Methods:

  • Two male patients with neglected Bennett fracture nonunion underwent surgical treatment.
  • The procedure involved suture button suspension using the Mini TightRope technique and small fragment excision.
  • Postoperatively, patients had 2 weeks of immobilization followed by progressive hand therapy.

Main Results:

  • Both patients achieved satisfactory healing and positioning of the thumb base at 5 months post-surgery.
  • Thumb motion returned to presurgery levels, with improvements in pain, pinch, and grip strength.
  • One patient resumed activities in 3 weeks; the other took 5 months due to a concurrent fracture.

Conclusions:

  • Suture button suspension combined with small fragment excision is a viable treatment for Bennett fracture nonunion.
  • This technique successfully restored thumb stability, mobility, and strength, potentially offering advantages over traditional methods.
  • Further research is warranted to confirm long-term efficacy and safety.
