Skin Pigmentation Affects ViOptix T.Ox Performance in Variably Pigmented Preclinical Model of Flap Ischemia and Congestion.
[BACKGROUND] Free flap monitoring is more difficult in patients with dark skin because ischemia and congestion can be masked by pigmentation. For this reason, adjunct methods such as cutaneous near-infrared spectroscopy are of elevated impo…

Intramuscular Microvascular Flow Sensing for Flap Monitoring in a Porcine Model of Arterial and Venous Occlusion.
[BACKGROUND] Commercially available near infrared spectroscopy devices for continuous free flap tissue oxygenation (StO) monitoring can only be used on flaps with a cutaneous component. Additionally, differences in skin quality and pigment…

Patient-Reported Lower Extremity Outcomes Following Fibula or Medial Femoral Condyle Free Flaps for Upper Extremity Defects.
[BACKGROUND] Free fibula flap (FFF) and medial femoral condyle (MFC) flap are commonly used for upper extremity osseous reconstruction, yet donor-site morbidity has never been systematically compared. [METHODS] Patients who underwent an FF…

A Wireless Near-Infrared Spectroscopy Device for Flap Monitoring: Proof of Concept in a Porcine Musculocutaneous Flap Model.
[BACKGROUND] Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are highly sensitive for detecting malperfusion. However, the clinical utility and user experience are limited by the wired connection betw…

Intramuscular Near-Infrared Spectroscopy for Muscle Flap Monitoring in a Porcine Model.
[BACKGROUND] Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are limited to flaps which carry a cutaneous paddle. As such, this useful and reliable technology has not previously been applicable to mus…

Pedicled Groin Flap for Reconstruction of Combined First Webspace and Dorsal Hand Contracture.
The combination of first webspace and dorsal hand contracture is a challenging reconstructive problem. Complete soft tissue release results in a large wraparound defect that spans the radial side of the palm, first webspace, and the transve…

Medial femoral trochlea flap reconstruction versus proximal row carpectomy for Kienböck's disease: a morphometric comparison.
Surgical options for advanced Kienböck's disease include proximal row carpectomy or lunate reconstruction with a medial femoral trochlea osteochondral flap. This study compares morphology of the proximal capitate and the medial femoral troc…

Outcomes of the Medial Femoral Trochlea Osteochondral Free Flap for Proximal Scaphoid Reconstruction.
[PURPOSE] To describe the radiographic, functional, and patient-reported outcomes (PROs) of medial femoral trochlea (MFT) osteochondral free flap reconstruction of the proximal scaphoid at approximately 2 years follow-up. [METHODS] Eleven …

Preliminary Clinical, Radiographic, and Patient-Reported Outcomes of the Medial Femoral Trochlea Osteochondral Free Flap for Lunate Reconstruction in Advanced Kienböck Disease.
[PURPOSE] We aimed to describe the radiographic, functional, and patient-reported outcomes (PROs) of medial femoral trochlea osteochondral free flap reconstruction of the proximal lunate in stage IIIA and IIIB Kienböck disease. [METHODS] E…

Harlequin Ichthyosis: A Surgical Perspective.
Limb constriction or encasement in patients with harlequin ichthyosis can cause tissue injury resulting in necrosis and auto-amputation. Surgical release of constrictive plaques has been previously demonstrated, but the perioperative and in…
