Subungual squamous cell carcinoma.

Subungual squamous cell carcinoma (SCC) is rare. We present a case of subungual SCC with invasion into the underlying bone and review the literature.

Chondrosarcoma of the head of the fifth metacarpal treated with an iliac crest bone graft and concurrent Swanson's arthroplasty.

Chondrosarcomas are rare malignant tumours of the bone with hyaline cartilage differentiation - only 1.5% affect the hands. Currently there is a limited range of techniques available to reconstruct the metacarpophalengeal joints affected by such neoplasias.

Reconstruction of large traumatic segmental defects of the femur using segmental allograft with vascularized fibula inlay.

Segmental defects of the distal femur following trauma pose a reconstructive challenge. A stable reconstruction capable of withstanding high forces while allowing early mobility is paramount. The Capanna technique of reconstruction combining allograft with vascularized bone graft provides such a construct and has been described for oncological resection.

Accidental burn injury during knee arthroscopy.

A case is described in which hot irrigation fluid used during a routine knee arthroscopy caused severe morbidity. The patient sustained full-thickness skin burns requiring debridement, a muscle flap, and split-skin grafting. The extent of the joint damage required fusion.

Pyoderma gangrenosum--case report.

We report the case of a woman of 34 years who had ulcerative colitis and atypical pyoderma gangrenosum. The pyoderma gangrenosum responded to conservative treatment.
