Non vascularized bone grafts

INTRODUCTION: The use of the dorsal hamate as a free osteochondral bone graft or vascularized bone flap has become the mainstay for large, comminuted middle phalanx volar lip fractures. To date, few studies have been conducted in the assessment of donor site morbidity for the hemi-hamate graft or flap, and none have discussed modes of repair or reconstruction of this donor site. METHODS: A retrospective analysis of 14 hemi-hamate arthroplasty (HHA) procedures, including 6 vascularized and 8 non-vascularized grafts, from two surgeons was performed...

In conflict zones like Syria, accessing specialized medical care presents significant challenges. Here, we present the case of a 22-year-old female with a giant cell tumor in her distal forearm, exacerbated by limited access to healthcare due to the Syrian conflict. Despite these obstacles, we successfully performed en bloc resection and reconstructed the defect with a proximal non-vascularized fibular graft, restoring arm function. This case underscores the critical importance of adapting to adverse circumstances to deliver essential medical interventions in conflict-affected regions...

Tuberculous dactylitis is infrequently seen after the age of 6 years. The index and middle fingers are the most common sites. Early diagnosis is essential to eradicate the infection. Delay in diagnosis and management leads to extensive involvement which may require surgical intervention. The current literature reveals conservative management gives satisfactory results in early stages. Though surgical intervention in Tuberculous dactylitis is seldom required, delay in diagnosis and management leads to extensive involvement of the bone and sequestration which does not respond to Anti Tubercular Therapy and needs staged surgical interventions...

PURPOSE: The study is aimed at evaluating the long-term (at a minimum follow-up of 10 years) impact of non-vascularized fibular harvest on the donor limbs. METHODS: There were 27 donor limbs (n = 19 children) available for retrospective radiological review. The graft was obtained bilaterally in eight patients. The following parameters were evaluated in the follow-up radiographs: continuity/non-continuity of fibular regenerate, width of the regenerated fibula, distal fibular station, medial proximal tibial angle, posterior proximal tibial angle, lateral distal tibial angle (LDTA), anterior distal tibial angle, and tibia diaphyseal angulation (interphyseal angles)...

INTRODUCTION: Osteoblastoma is a rare, benign, bone-forming tumor accounting for <1% of all primary bone tumors. It has a predilection for the posterior elements of the spine and metaphysis and diaphysis of long bones. The occurrence of this tumor in the metatarsal region is rare. We report such the case of a metatarsal osteoblastoma which was treated with wide excision and non-vascularized fibular autograft: a reliable method of reconstruction. CASE REPORT: A 25-year-old woman presented with progressive pain and swelling over the right foot for 4 years...

INTRODUCTION: Neck of femur fractures (NOF) in younger adults are often treated by head-preserving fixation procedures. Non-union is an infrequent but troublesome complication following internal fixation, especially in atypical presentations. Vascularized (VFG) and non-VFG (NVFG) fibular grafting and realignment procedures have been described as an adjunct to internal fixation. Reports are rare regarding the versatility of fibular grafts, their use, and their outcomes in the United Kingdom...

INTRODUCTION: Aneurysmal bone cysts (ABCs) are non-neoplastic expansile, vascular, osteolytic benign tumors in the long bone, spine, and sternum. The location in the pelvis is sparse. CASE REPORT: A 12-year-old female presented with pain in her left pelvis for 6 months. On radiological examination, we found an expansile balloting lytic lesion involving almost the whole ilium and sparing the hip joint. There were multiple fluid levels seen on magnetic resonance imaging...

The reconstruction of the whole orbitozygomatic framework (OZF) is complex and can be encountered in cases of congenital midface deformity, after tumor ablative surgery and in severe facial trauma. Nowadays, surgeon has a wide range of available techniques that have continually grown over the past years, optimizing the surgical management and the aesthetical outcomes. Among them, the autologous bone graft (ABG) remains one of the most suitable options : ABG is easy to harvest and has optimal biological properties for bone healing...
