PURPOSE: We present the results of a study on the anatomy of the ascending branch of the lateral circumflex femoral artery (AB-LCFA) and the use of the pedicled iliac bone flap transfer perfused by AB-LCFA combined with external fixation for the treatment of the nonunion of upper femoral shaft fractures. METHODS: The orientation, diameter, length, and distribution of the AB-LCFA from 40 lower limbs of adult cadavers were dissected and measured. From 2000 to 2012, 13 patients with nonunion of upper femoral shaft fractures underwent pedicled iliac bone flap transfer perfused by the AB-LCFA combined with external fixation...

PURPOSE: The results for fixation of comminuted posterior wall acetabular fractures are not very promising with reported complications in terms of osteoarthritis, nonunion and malunion which subsequently require conversion to total hip arthroplasty. The conversion to total hip arthroplasty is possible in patients over 50 years of age but not in younger patients. So this requires new methods for salvage of the native hip in young patients. METHODS: There were six patients in our series with highly comminuted posterior wall acetabular fractures where the fragments were excised and the gap filled with tricortical anterior iliac-crest strut autograft, fixed with screws and plate...

Non-union is incomplete consolidation of a fracture, without effective formation of a uniting callus. Despite better understanding of the physiology of bone consolidation, management of tibial non-union remains a challenge for orthopedic surgeons. Several treatments have been developed in recent decades, and we now have a range of techniques, with indications based on type of non-union, prior treatments, available equipment, and the surgeon's experience. Firstly, there are surgical techniques such as osteo-periosteal decortication, cancellous iliac graft, or inter-tibiofibular graft...

Introduction: Isolated, neglected medial malleolus nonunion cases are a rare entity in orthopedic literature. All studies (except one) have described the use of compression screws (with or without plates) for medial malleolar nonunion management. In acute fractures, tension band wiring (TBW) has shown excellent results both in biomechanical and in clinical studies. On the contrary, it has seldom been used in nonunion or in neglected cases. Case Report: We describe a 6-month-old neglected medial malleolus gap nonunion case who presented with progressive pain and limp...

Introduction: Odontoideum bone or the mobile odontoid process is one of the rarest malformations of the cervico-occipital hinge. It exposes to the atlo-axial instability and to the risk of bulbo-medullary compression threatening then the vital and functional prognosis. We report the case of a 16-year-old patient who was the victim of a raod accident resulting in acervical spine injury. Radiological investigation found an odontoideum bone malformation associated with C1C2 dislocation. Case Report: A 16-year-old patient with no medical history had a road accident...

We present 20 patients with established proximal pole scaphoid nonunions treated with curettage and cancellous autograft from the distal radius and screw fixation. Fractures with significant proximal pole fragmentation were excluded. Patients were treated at a mean of 26 weeks after injury (range 12-72). Union occurred in 18 of 20 patients (90%) based on computed tomographic imaging. The two nonunions that did not heal were treated with repeat curettage and debridement and iliac crest bone grafting without revision of fixation...

INTRODUCTION: Pelvic apophyseal avulsion can limit young athletes' performance for months and may result in permanent disability. Nonoperative treatment is most commonly preferred, while surgical management with reduction and fixation is reserved for selected cases. Our aim was to evaluate outcomes of operative management of pelvic apophyseal avulsions in a series of adolescents and young adult athletes. MATERIALS AND METHODS: Operative room registries and medical records were reviewed to identify patients who received surgical treatment for pelvic apophyseal avulsions who were younger than 24 years and with a minimum of 12 month follow-up...

REVIEW
M Wellmann, M-F Pastor, T Smith
Posterior shoulder instability has a markedly lower incidence than anterior shoulder instability. It has a wide spectrum of clinical symptom manifestations and the overwhelming number of patients lack a traumatic primary dislocation. In addition to a detailed medical history, a specific clinical examination with the help of standardized provocation tests is essential for the diagnostics. For the detection of structural posterior capsule and labral lesions in cases of chronic courses, magnetic resonance imaging (MRI) should be used with an intra-articular contrast agent...

PURPOSE: U-shaped sacral fractures are extremely rare injuries that usually occur as a result of falls from considerable heights. Almost all treatment methods described to date aim solely at stabilizing the fracture but do not contribute to supporting the reduction of such fractures. Using existing implants the purpose of this study is to present a surgical technique that facilitates both the reduction and the stabilization of these injuries. The presented technique was evaluated in a series of three cases...

Low transverse sacral fractures are rare, with only two published reports regarding their surgery. The complication associated with surgery for sacral fractures is the prominence of implants. In addition, screw fixation below S3 is impractical. We performed posterior sacral fixation using S2 alar iliac (S2AI) screws and sacral sublaminar wires for low transverse sacral fractures. Case 1 was 65-year-old male with an S2-3 transverse sacral fracture. We performed laminectomy (S2-3) and passed ultrahigh molecular weight polyethylene (UHMWPE) cables from laminectomy area to the third posterior sacral foramina...

With increasing life expectancy, fragility fractures of the pelvic ring are seen more frequently. Although their osteosynthesis can be very challenging, specific biomechanical studies for investigation of the fixation stability are still lacking. The aim of this study was to biomechanically evaluate four different fixation methods for sacrum Denis type II fractures in osteoporotic bone. Unstable Denis type II vertical sacrum fractures were created in 16 human pelves. Their osteosynthesis was performed with one sacro-iliac screw, posterior sacral plating, triangular fixation, or spino-pelvic fixation...

Giant-cell tumour of the tendon sheath (GCTTS) is a soft tissue tumour that may invade bone, causing an intrinsic osseous lesion or instability on radiographs. A case with scaphoid instability caused by a histologically-confirmed neighbouring GCTTS has rarely been described in the literature. No definite and radical method is available for the treatment of GCTTS. This report describes an unusual case of a 22-year-old woman who previously experienced a GCTTS in her right elbow, which was removed 10 years earlier...

PURPOSE: To evaluate the efficacy of plate fixation on cervical alignment after anterior cervical discectomy and fusion (ACDF) using a stand-alone cage (ACDF-CA), compared to ACDF performed using a cage and plate fixation (ACDF-CP) and ACDF using autologous iliac bone graft and plate fixation (ACDF-AP), for the treatment of one- or two-level cervical degenerative disease. A second objective was to assess the clinical and radiological outcomes between the groups. METHODS: A total of 247 patients underwent ACDF and were divided into three groups: those who underwent ACDF-CA (n = 76), ACDF-CP (n = 82) or ACDF-AP (n = 89)...

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...
