Surgical repair of rib fractures in 14 neonatal foals: case selection, surgical technique and results

EQUINE VETERINARY JOURNAL, Issue 7 2004
F. BELLEZZO
Summary Reasons for performing study: Fractured ribs are encountered quite frequently in newborn Thoroughbred foals, often with fatal outcome. Surgical repair of fractures therefore requires consideration as a means of reducing mortality. Objectives: To evaluate the repair of rib fractures using internal fixation techniques in foals at 2 different equine hospitals following similar diagnostics and case selection. Methods: The records of 14 foals that underwent internal fixation of fracture ribs were reviewed. Subject details, clinical presentation, diagnosis, surgical technique, post operative care and complications were recorded. Follow-up information was obtained in 7 foals. Results: The fractured ribs were reduced and stabilised using reconstruction plate(s), self-tapping cortical screws and cerclage wire in 12 cases, Steinmann pins and cerclage wires in 1 case and both techniques in 1 case. Not every rib was reduced on each case. Surgical reduction was performed on an average of 2 ribs, range 1,3 ribs in each foal. At the time of writing, 4 foals had been sold, one age 2 years was in training and 2 others died from unrelated causes. Conclusions: Our data support the use of surgical stabilisation utilising reconstruction plates, self-tapping cortical screws and cerclage wire for selected cases of thoracic trauma in neonatal foals. The use of Steinmann pins may be suboptimal due to cyclic failure, implant migration and the potential for iatrogenic internal thoracic trauma. Potential relevance: Foals with existing extensive internal thoracic trauma resulting from rib fracture(s), or the potential for such trauma, previously considered to have a guarded to poor prognosis for survival, may be successfully managed with internal fixation of selected fracture sites.

Efficacy of small reconstruction plates in vascularized bone graft mandibular reconstruction,

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 7 2006
D. Gregory Farwell MD, FACS
Abstract Background: Utilization of vascularized bone grafts rigidly fixated with titanium reconstruction plates is the method of choice for reconstruction of segmental mandibular defects. We hypothesized that the use of the newer 2.0-mm locking reconstruction plate (LRP) is not associated with higher rates of complications when compared with larger, previously used plating systems. Methods: A retrospective case series of 184 patients undergoing 185 vascularized bone graft reconstruction procedures of the mandible was conducted. Results: There were 37 plate complications. There was no significant difference in complication rates for the 2 most used plate types (14.5% with the 2.0-mm LRP and 22.2% with the 2.4-mm LRP). Conclusions: Use of the smaller 2.0-mm LRP was not associated with an increase in the complications of plate fracture, exposure, infection, or nonunion. Because of its lower profile and ease of application, the 2.0-mm LRP is our plate of choice for mandibular reconstruction. © 2006 Wiley Periodicals, Inc. Head Neck, 2006 [source]

Rehabilitation by means of osseointegrated implants in oral cancer patients with about four to six years follow-up

JOURNAL OF ORAL REHABILITATION, Issue 3 2006
J. SEKINE
summary, This paper describes the reconstruction of mandibular defects in four oral cancer patients using iliac crest bone grafts and osseointegrated implants. In three patients, reconstructive surgery using a reconstruction plate and free forearm skin flap was performed following tumour and segmental mandibular resection. After 7,9 months, mandibular reconstruction with a free iliac bone graft was carried out. In one patient, reconstructive surgery was performed with vascularized iliac bone grafting with an anterolateral thigh flap at the same time as the tumour resection. Fixtures were placed in the transplanted bone, and abutments were connected 6,9 months later together with vestibuloplasty. Gingival grafts were used to replace the skin flap around abutments. All implants survived throughout the approximately 4,6 years observation time. Marginal bone loss of the graft was originally several millimetres but less than 1·5 mm. Bone loss as well as management of peri-implant soft tissue was also discussed. [source]

Mandibular reconstruction after resection of benign tumours using non-vascularised methods in a series of patients that did not undergo radiotherapy

ORAL SURGERY, Issue 1 2009
D. Mehrotra
Abstract Aim:, A case series analysis of 52 consequent subjects of immediate mandibular reconstruction after tumour resection using non-vascularised methods, undertaken at U.P. King George's University of Dental Sciences and King George's Medical University, is being reported. To assess the success of reconstruction on subjective and objective evaluation based upon Mandibular Reconstruction Assessment Scale (MRAS) questionnaire. Methods:, Patients with benign mandibular tumours irrespective of age, sex, site and socio-economic status were included. Primary reconstruction was carried out after resection in two surgical units on surgeon's choice using stainless steel wire (6/52; 12%), stainless steel reconstruction plate (10/52; 19%) or titanium reconstruction plate (36/52; 69%) without bone graft (23/52; 44%) or with bone graft (29/52; 56%). Bone grafts were harvested from iliac crest (21/52; 40%), rib (2/52; 4%) and an additional pectoralis major myocutaneous flap with iliac crest bone graft (6/52; 12%) to provide cover to the reconstruction plate was also used. Results:, The primary outcome measurements were wound healing, mouth opening, chewing efficiency, jaw movements, cosmetic achievement and speech on a five-point scale, all of which improved significantly after surgery. The overall complication rate was 17%. Three patients (6%) had loosening of the screw, two (4%) showed dehiscence of the plate, two (4%) showed tumour recurrence and one (2%) had infection of the graft that was subsequently removed. Conclusion:, Titanium reconstruction plates with iliac crest graft provided good result in the absence of microvascular reconstruction because of unavailable long operating time and lack of expertise. Long-term satisfactory rehabilitation can be achieved using removable dentures or prosthesis on dental implants on the contraption provided by the non-vascularised tissue despite non-calcified bone visible on the skiagram.

The resistance of maxillofacial reconstruction plates to biofilm formation in vitro

THE LARYNGOSCOPE, Issue 11 2003
Brian E. Emery MD
Abstract Objectives/Hypothesis: Bacterial biofilms, bacteria surrounded by a protective glycocalyx, have been demonstrated on bioimplants placed within and outside of the head and neck region. The presence of the biofilm often makes decontamination of an infected implant impossible, requiring removal of the implant. Infections attributable to biofilm formation within the facial skeleton after reconstruction with implants may result in delayed union, fibrous union, malunion, nonunion, and malocclusion. These complications often require removal of the implant and secondary surgery. Although the incidence of infections necessitating implant removal is relatively low, the increased numbers of implants being placed make this a growing problem. Previous work in the authors laboratory has demonstrated a resistance to biofilm formation on different types of pressure-equalizing tubes. The hypothesis evaluated in the study is that such resistance to biofilm formation is due to the inability of bacteria to adhere to the tubes because of the material's smoothness or surface charge. Study Design: A controlled observational study. Methods: Scanning electron microscopy was used to evaluate the formation of biofilms in vitro for a common strain of Staphylococcus aureus on four implantable materials. The implantable materials included titanium and polylactide resorbable plates. Results: Consistent with the authors' prior findings, they were able to produce bacterial biofilm reliably on a silicone pressure equalizing tube but were unable to demonstrate biofilm formation on the titanium or resorbable implants. Conclusion: The absence of biofilm formation on these implants can best be explained by the surface charge or polarity properties of these materials. These findings are consistent with the relatively low incidence of infections among patients receiving these implants in maxillofacial applications. [source]
