Fractures: Bone Repair

4.6K
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...

Summary
This summary is machine-generated.

Volar scaphoid plating achieved a 90.6% union rate in scaphoid nonunion patients, offering improved rotational stability. This technique may be advantageous for specific fracture patterns, enhancing patient outcomes.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Traumatology

Background:

  • The Medartis volar scaphoid plate is a variable angle titanium locking device designed for the volar aspect of the scaphoid.
  • It functions as a bridging device without inherent compression, offering potential advantages in rotational stability for complex scaphoid nonunions.
  • The plate has been utilized in cases of nonunion and with vascularized grafts, and may serve as a buttress for deformity correction.

Purpose of the Study:

  • To evaluate the outcomes of patients with scaphoid nonunion treated with volar scaphoid plating.
  • To identify surgical techniques that can improve the success rate of this plating method.

Main Methods:

  • A retrospective review of patients who underwent scaphoid volar plating for nonunion was conducted.
  • Operations were performed by fellowship-trained hand surgeons across two centers, with a minimum 6-month follow-up.
  • Data collected included demographics, patient-reported outcomes (PRWE, qDASH), visual analogue scores, range of motion, and grip strength, supplemented by radiological review.

Main Results:

  • Thirty-two patients were assessed, with a mean age of 25 years; 90.6% (29/32) achieved union on CT scan.
  • Clinical assessments in 25 patients showed a mean qDASH of 12.5 and a mean PRWE of 11.
  • Mean range of motion was 115 degrees, and mean grip strength was 39 kg, comparable to the nonoperated side (41 kg).

Conclusions:

  • The volar scaphoid plate functions as an internal bridging device, providing stability when used with structural grafts and accurate reduction.
  • Potential complications include impingement on the volar lip of the radius, particularly with proximal fractures.
  • Optimal utilization is for mid to distal scaphoid waist fractures.
