Clinical and radiographic outcomes of negative pressure wound therapy combined with polymethylmethacrylate sealant for wound management of Gustilo type III open tibia fractures.

Objective: This study aimed to introduce a new wound management method combining negative pressure wound therapy and polymethylmethacrylate sealant for Gustilo type III open tibia fractures and to evaluate its clinical outcomes.

Methods: Among 186 patients who visited our institution for the treatment of open tibia fractures between January 2016 and December 2019, 20 male patients who sustained Gustilo type III open tibia fractures and were compelled to undergo delayed flap coverage using negative pressure wound therapy combined with polymethylmethacrylate sealant due to initial critical condition were enrolled in this study. We retrospectively investigated patients' demographics, interval between the injury and flap coverage, number of negative pressure wound therapy changes, flap survival, bone union time, and infection-induced complications.

Simple curettage and allogeneic cancellous bone chip impaction grafting in solitary enchondroma of the short tubular bones of the hand.

Enchondroma is the most common bone tumor in the hand. While standard surgical procedure is intra-lesional excision and bone grafting, there is a dispute between allogeneic bone, autogenous bone, and synthetic bone substitute grafting. Diverse adjuvant treatments have been introduced to reduce recurrence, but results are mixed with controversies.

Pancarpal dissociation, a very rare type of injury: A case report.

Rationale: Pan-carpal dissociation is very rare injury and there is little information as to diagnosis, treatment, and prognosis of this injury.

Patient Concerns: A 35-year-man presented to our hospital with severe pain and swelling of the left wrist and forearm after slipping and falling while riding a motorcycle.

Diagnosis: The wrist simple radiographs demonstrated unrecognizable severe fracture-dislocation of the carpal bones concomitant with fractures of the radioulnar shaft.

Use of injectable acellular dermal matrix combined with negative pressure wound therapy in open diabetic foot amputation.

Objective: Skin grafts after negative pressure wound therapy (NPWT) and acellular dermal matrix (ADM) usage have both been useful for treating diabetic foot amputation. We hypothesised that injectable ADM combined with NPWT would be more useful than NPWT only for healing after amputation in patients with diabetic foot ulcers (DFUs). The aim of this study was to investigate the clinical outcomes of injectable ADM combined with NPWT in patients with DFU who have undergone amputation.
