Congenital pseudarthrosis of the clavicle (CPC) is a very rare pathology of which over 200 cases have been reported. Usually discovered during the first months of life, CPC is characterised by a definitive bone defect in the middle third of the clavicle. Generally asymptomatic, the pseudarthrosis of the clavicle can cause aesthetic issues and functional symptoms indicating a surgical repair. Different reconstruction techniques have been reported with various complications. We present a 14-year-old boy diagnosed with CPC and concerned about the cosmetic aspect of a swelling of his right clavicle...

OBJECTIVE: In the present retrospective study, we aimed to analyze the results of treatment for recalcitrant distal tibial nonunion using Masquelet technique with locking plate as a definitive external fixator. MATERIALS: We included 15 consecutive cases of distal tibial nonunion treated at our hospital between January 2012 and December 2015. The reconstructive procedure comprised debridement of the nonunion site, deformity correction, stabilization with an external locked plate, defect filling with cement spacer for inducing membrane formation, and bone reconstruction using a cancellous bone autograft (Masquelet technique)...

The Masquelet technique is a strategy for management of segmental bone defects. It is a two-stage procedure that involves inducing a synovial-like membrane that can be used for a bone graft. Segmental bone defects can occur following trauma and can accompany traumatic brain injury. There is a well-documented, albeit debated, association between traumatic brain injury and increased rate of new bone formation. Here, we present a case of unexpected callus formation in a segmental femoral fracture. The patient had a traumatic brain injury and was treated with the first stage of the Masquelet technique...

The gold standard technique for treating non-union of the clavicle is based on corticocancellous bone graft harvested from the iliac crest and fixation with a plate. In cases of large clavicular defects, this surgical procedure becomes ineffective and only a complex bone reconstruction can be considered. In the herein study we report on a clavicular non-union which was associated with a 4cm bone defect that was managed successfully with optimum fixation and the Chamber Induction Technique (C.I.T)-formation of the masquelet membrane- and subsequent biological augmentation with a composite bone graft...

The induced membrane technique for reconstruction of bone defects has proved its effectiveness and is now widely accepted. The 2 stages procedure, implying a cement spacer in the first stage and a huge bone graft in the second stage, responds to rigorous technical details involving each phase of the procedure. Prerequisites for the technique, cement spacer, bone fixation, time between the 2 stages, grafting, and postoperative course are reported and discussed.

INTRODUCTION: Soft tissue defect on lower limb can result in an intractable wound. Surgeons resort in flaps to cover these injuries. Including fascia as in the case of a fasciocutaneous flap increases survey of the flap. Rising a perforator flap avoids to sacrifice a major vessel whence the nourishing perforator artery is born. We wanted to explore suprafascial distribution of the fibular skin perforator arteries supposing possible to find out a vascular axis composed of anastomoses of the fibular perforator vessels...

The fasciocutaneous lateral arm flap is a workhorse flap in upper extremity reconstruction. However, its adipofascial variant is not widely used. The technique can be used in various clinical scenarios. The adipofascial flap can be transposed to circumferentially wrap the radial nerve with a pliable, vascularized fat and fascial envelope, mimicking the natural fatty environment of peripheral nerves. This technique has the advantage of providing a scar tissue barrier, a barrier to hardware irritation and a milieu for vascular regeneration of the nerve...

REVIEW
F Saxer, H Eckardt
The Masquelet procedure or induced membrane technique presents a treatment option for relatively large osseous defects, e.g. after trauma, tumour resection or osteomyelitis even in the presence of unfavourable soft tissues. Initially developed at the end of the last century by the French surgeon Masquelet, the technique relies on a bioactive membrane that forms a foreign body reaction around a cement spacer. This spacer is implanted in the residual defect after rigorous debridement of bone and soft tissue during a first-stage procedure...

Among various infections, chronic osteomyelitis is one of the most challenging in terms of treatment. This infection is more common among patients with open fractures and those who have undergone elective orthopedic procedures. The treatment of osteomyelitis requires high antibiotic doses and an aggressive and multifaceted surgical approach. The use of parenteral antibiotics alone, without debridement, is not sufficiently effective, due to the formation of sequestra and the low vascularity of the affected area...

PURPOSE: Posttraumatic bone defects in the setting of severe open injuries of the lower extremity present a significant challenge for orthopaedic trauma surgeons. The induced membrane technique, also known as the Masquelet technique, has been shown to be generally successful in achieving bony union. This video demonstrates the use of the Masquelet technique for a large (18 cm) femoral defect. METHODS: The Masquelet technique is a 2-stage process. The first stage involves debridement of all devitalized tissue, using open reduction and internal fixation, and placement of a cement spacer with or without antibiotics...

INTRODUCTION: Assessment of a resident's microsurgical competency with the rodent model remains the current gold standard. However, cost and ethical issues related to animal welfare may limit training opportunities. Therefore, synthetic alternatives such as silicone tubes have been developed to provide easy access to training, shorten the learning curve, and have been incorporated into microsurgical courses as a low-fidelity model for basic skills acquisition. This study compares the use of polyvinyl alcohol (PVA) gelatin tubes with silicone for resident microsurgical training...

BACKGROUND: The Masquelet-induced-membrane technique is a commonly used method for treating segmental bone defects. However, there are no established clinical standards for management of the induced membrane before grafting. QUESTIONS/PURPOSES: Two clinically based theories were tested in a chronic caprine tibial defect model: (1) a textured spacer that increases the induced-membrane surface area will increase bone regeneration; and (2) surgical scraping to remove a thin tissue layer of the inner induced-membrane surface will enhance bone formation...

BACKGROUND: Cement spacers (Masquelet technique) have traditionally been used for the treatment of segmental bone defects. However, no reports have used cement spacers for the treatment of small/partial segmental bone defects associated with osteomyelitis and compared the outcomes with cement beads. METHODS: We retrospectively analysed 40 patients with post-traumatic osteomyelitis of the tibia who underwent treatment, which was performed in two stages. In the first stage, thorough debridement was performed, and bone defects were filled with either antibiotic-impregnated cement beads (bead group, 18 patients) or spacers (spacer group, 22 patients)...

The treatment after open and infected fractures with extensive soft tissue damage and bone deficit remains a challenging clinical problem. The technique described by Masquelet, using a temporary cement spacer to induce a membrane combined with reconstructive soft tissue coverage, is a possible solution. This study describes the work-up, operative procedure, complications, and the outcome of a homogenous group of patients with an open and infected tibia fracture and segmental bone loss treated with the Masquelet technique (MT)...

Non-union is a devastating consequence of a fracture. Non-unions cause substantial patient morbidity with patients suffering from loss of function of the affected extremity, increased pain, and a substantial decrease in the quality of life. The management is often associated with repeated, unsuccessful operations resulting in prolonged hospital stays, which has social and economic consequences to both the patient and the healthcare system. The rates of non-union following intramedullary (IM) nailing vary according to anatomical location...

Large segmental bone defect reconstruction with sufficient functional restoration is one of the most demanding challenges in orthopedic surgery. Available regenerative treatment options, as the vascularized bone graft transfer, the Masquelet technique or the Ilizarov distraction osteogenesis, are associated with specific indications and distinct limitations. As an alternative, a hollow cylindrical ceramic-polymer composite scaffold (beta-tricalcium phosphate and poly-lactid co-ε- caprolactone), facilitating a strong surface guiding effect for tissue ingrowth (group 1; n = 6) was investigated here...
