Biological Versus Nonbiological Reconstruction of the Ulnar Collateral Ligament of the Thumb Metacarpophalangeal Joint: A Retrospective Study.

Purpose: The purpose of this study was to compare clinical and radiologic outcomes of biological ligament reconstruction (BLR) versus nonbiological ligament reconstruction (NBLR) for chronic injuries involving the ulnar collateral ligament of the thumb's metacarpophalangeal joint.

Methods: Forty-two patients who underwent static BLR (n = 24) or NBLR (n = 18) were included in this retrospective analysis. Preoperative, postoperative, and contralateral thumb measurements (clinical evaluation, radiographs, and subjective outcome questionnaires) were compared over a mean of 38 months of follow-up.

Vascularized Ulnar Periosteal Pedicled Flap for Upper Extremity Reconstruction in Adults: A Prospective Case Series of 11 Patients.

Purpose: We hypothesized that a vascularized ulnar periosteal pedicled flap (VUPPF) is a versatile graft applicable in adult patients that yields good outcomes and is a reliable alternative to other vascularized bone grafts to reduce both the technical demands and donor site morbidity of other options.

Methods: We reviewed 11 adult patients who underwent surgical treatment of forearm atrophic nonunion with a VUPPF. Patients' demographics, outcomes (measured by pain on the visual analog scale; Quick Disabilities of the Arm, Shoulder, and Hand score; range of motion; and grip strength), and associated complications were reported.

Partial trapeziectomy and pyrocarbon interpositional arthroplasty for trapeziometacarpal osteoarthritis: minimum 8-year follow-up.

We undertook a retrospective study to evaluate minimal 8-year outcomes of 46 trapeziometacarpal joints (46 patients) treated with pyrocarbon implant arthroplasty after partial trapeziectomy for trapeziometacarpal joint osteoarthritis in two different hand surgery units. The mean follow-up interval was 9.5 years (average 113 months with a range 97-144 months).

Vascularized Thumb Metacarpal Periosteal Flap for Scaphoid Nonunion in Adolescents: A Prospective Cohort Study of 12 Patients.

Purpose: To evaluate clinical and radiological outcomes after surgical treatment of scaphoid nonunion in adolescents with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF).

Methods: Twelve patients younger than 18 years with scaphoid nonunion, who underwent a VTMPF procedure without bone grafting, were included for this prospective cohort study, at a mean follow-up of 10.2 months.

Dorsolateral Biplane Closing Radial Osteotomy and Lunate Fixation for Stage IIIC Kienböck Disease: A New Surgical Approach.

The treatment of advanced-stage Kienböck disease (KD) remains highly controversial. Particularly important is stage IIIC KD, which includes patients with a lunate coronal fracture. The purpose of this paper was to describe a new approach to KD in patients with Lichtman stage IIIC KD, and our results using it.

Vascularized thumb metacarpal periosteal pedicled flap for scaphoid nonunion: An anatomical study and pediatric case report.

Purpose: Through an anatomical review, the primary aim of this study was to delineate the dorsal thumb metacarpal (TM) periosteal branches of the radial artery (RA). In addition, we report here the clinical utility of a vascularized TM periosteal pedicled flap (VTMPF), supplied by the first dorsal metacarpal artery (FDMA), in a complex case of scaphoid nonunion.

Methods: Ten latex-colored upper limbs from fresh human cadavers were used.
