Femoral neck fractures after internal fixation of trochanteric fractures with implants in situ in adults: A systematic review.

Introduction: Femoral neck fractures (FNF) after internal fixation of trochanteric fractures (AIFTF) with the implant in situ (WIIS) are uncommon. Publications of FNFAIFTFWIIS are rare. The purpose of this systematic review of the literature is to report on the frequency, risk factors, mechanisms, clinical presentation, diagnostic and therapeutic modalities, outcomes and the eventual prevention of this complication.

Femoral neck fractures after removal of hardware in healed trochanteric fractures.

Introduction: Hardware removal in healed trochanteric fractures (TF) in the absence of infection or significant mechanical complications is rarely indicated. However, in patients with persistent pain, prominent material and discomfort in the activities of daily living, the implant is eventually removed. Publications of ipsilateral femoral neck fracture after removal of implants from healed trochanteric fractures (FNFARIHTF) just because of pain or discomfort are rare.

Barriers to Clinical Research in Latin America.

Enhancing health research capacity in developing countries is a global health priority. Understanding the orthopedic burden of disease in Latin America will require close partnership between more-developed and less-developed countries. To this end, the Osteosynthesis and Trauma Care Foundation assembled a research consortium of Latin-American orthopedic leaders.

EPIDEMIOLOGY AND TREATMENT OF MONTEGGIA LESION IN ADULTS: SERIES OF 44 CASES.

Objective: To analyze the epidemiology, treatment and outcome of a series of adult patients with Monteggia lesion treated in Uruguayan institutions.

Methods: This is a retrospective article, we retrospectively identified from two Uruguayan institutions 44 adult patients with Monteggia lesion and analyzed their characteristics including Bado classification, associated injuries, treatment modality and outcome (Morrey score).

Results: Using Bado classification, 23 cases (52%) were type II, 12 (27%) type I, seven (16%) type IV and two cases (5%) type III.

Proximal femoral fractures and vascular injuries in adults: Incidence, aetiology and outcomes.

Introduction: Vascular injuries (VI) presenting during internal fixation (IF) of proximal femoral fractures (PFF) are potentially limb- and life-threatening. The purpose of this systematic review of the literature is to report on their incidence, associated complications and to give special emphasis in their prevention.

Materials And Methods: A comprehensive review of the literature was undertaken using the PRISMA guidelines with no language restriction.

Avascular necrosis of the femoral head following trochanteric fractures in adults: a systematic review.

Introduction: Avascular necrosis of the femoral head (ANFH) following trochanteric fractures (TFx) is infrequent. The causal relationship between ANFH and TFx remains controversial. Although several major risk factors for ANFH have been proposed, most of them remain under discussion.

Scapula fractures: interobserver reliability of classification and treatment.

Objectives: There is substantial variation in the classification and management of scapula fractures. The first purpose of this study was to analyze the interobserver reliability of the OTA/AO classification and the New International Classification for Scapula Fractures. The second purpose was to assess the proportion of agreement among orthopaedic surgeons on operative or nonoperative treatment.

Vanadium pentoxide inhalation provokes germinal center hyperplasia and suppressed humoral immune responses.

Vanadium, an important air pollutant derived from fuel product combustion, aggravates respiratory diseases and impairs cardiovascular function. In contrast, its effects on immune response are conflicting. The aim of our work was to determine if spleens of vanadium-exposed CD1 mice showed histological lesions that might result in immune response malfunction.

The treatment of subtrochanteric nonunions with the long gamma nail: twenty-six patients with a minimum 2-year follow-up.

Objective: To assess the efficacy of the long Gamma nail in the treatment of subtrochanteric nonunions.

Design: Retrospective.

Setting: Multicenter (university teaching hospital, private centers).

Intertrochanteric-subtrochanteric fractures: treatment with the long Gamma nail.

Objective: To evaluate the outcome of the treatment of intertrochanteric-subtrochanteric fractures (subtrochanteric fractures with extension into the greater trochanter and the piriformis fossa) using the long Gamma nail.

Design: Prospective, consecutive.

Setting: Multicenter (private clinics).

Occult severe hyperflexion sprain of the lower cervical spine.

Three patients with occult severe hyperflexion sprain of the lower cervical spine are described. Because the spine radiographs obtained at the time of trauma were physiologically normal, the complete instability was initially overlooked. The authors recommend an algorithm for adequate diagnosis of this condition.

Anterolateral dislocation of the lumbosacral junction.

An unusual case of anterolateral fracture-dislocation of the lumbosacral junction is reported, and seven additional cases from the literature are discussed. The mechanism of injury is forced hyperflexion and shear. The prevalence of neurologic involvement is high, as is the number of fractures of the adjacent spinal elements and the occurrence of disk fragments in the spinal canal.

Slow, gradual external fixation distraction for treatment of postburn knee flexion contracture.

Although surgical release and reconstruction have been used extensively to treat severe postburn knee flexion contractures, the degree of correction is sometimes unsatisfactory, and the procedure is not exempt from significant complications. Based on the principle of slow, gradual external fixation distraction, we have designed a triangular articulated frame to be mounted with the ASIF-BM fixator to deal with joint flexion contractures. One successfully treated patient is reported.

The dynamic ASIF-BM tubular external fixator in the treatment of open fractures of the shaft of the tibia.

The dynamic ASIF-BM external fixator incorporates telescopic tubes for axial dynamization and angled bayonet screws to keep the tubes parallel to the bone axis, that is essential for gliding, and adjustment of rotation. The results after treatment of 70 type II and III open tibial fractures with static ASIF and dynamic ASIF-BM frames were analysed. Of the fractures, 32 were treated with the delta ASIF static frame, the other 38 with delta and uniplanar dynamic ASIF-BM frames.

Ipsilateral open fracture of the femur and tibia treated using the dynamic ASIF-BM tubular external fixator: case reports.

Two cases of ipsilateral open fracture of the femur and tibia treated using the dynamic ASIF-BM tubular external fixator are described. Results were very good, with short periods of occupational disability. These cases support primary stable osteosynthesis of these simultaneous fractures and the value of dynamic axial external fixation as a definitive treatment of open fractures of the femur and tibia shaft, either isolated or simultaneous.

A combined therapeutic protocol for aseptic nonunion of the humeral shaft: a report of 25 cases.

Twenty-five patients with aseptic nonunion of the humeral shaft, treated by a combined therapeutic procedure, are reported. The initial treatment of these 21 closed and four open fractures had been nonoperative in 21 patients and surgical in four. Seven further open procedures had been performed in four of these patients, also undergoing failure.

The AO tubular external fixator in the treatment of open fractures and infected non-unions of the shaft of the femur.

A series of 14 cases of open fractures of the shaft of the femur and another group of 13 cases of infected non-union of the shaft of the femur are reported. They were treated with the AO tubular external fixator. The complications and results are assessed and it is concluded that the AO external fixator system has a valuable part to play in these difficult cases.

Large segmental necrosis of the tibia with deep infection after open fracture.

Fifteen patients with large segmental necrosis of the tibia with deep infection, following open fractures, were treated according to the Burri-Papineau protocol. After radical debridement, the segmental bone defects averaged 8.4 (5-15) cm.

Dislocation of the shoulder with fracture of the ipsilateral shaft of the humerus.

Three cases of dislocation of the shoulder and ipsilateral fracture of the shaft of the humerus are reported. The literature is reviewed. It is suggested that X-ray films should be taken of the shoulder and elbow in all patients with fractures of the shaft of the humerus.

Simultaneous ipsilateral trochanteric and femoral shaft fracture.

Thirteen cases of concomitant trochanteric and shaft fracture of the same femur are reported. The hip fracture was initially missed in two cases. Osteosynthesis of both fractures was performed in ten cases.

Posterior dislocation of the ulna at the elbow with associated fracture of the radial shaft.

An exceptional case of posterior dislocation of the ulna at the elbow, associated with fracture of the radial shaft, is reported. Diagnosis was established with anteroposterior and lateral radiographs of the forearm, elbow and wrist. Treatment consisted of closed reduction of the ulnar dislocation and open reduction and internal fixation of the radius with an AO plate.

Traumatic dislocation of the hip with separation of the proximal femoral epiphysis. Report of two cases and review of the literature.

Traumatic hip dislocation with separation of the proximal femoral epiphysis is a rare injury. Twenty-six observations collected from the literature, together with two further cases presented in this paper, were statistically evaluated. Two types of injury were considered: T1, dislocation with complete separation and displacement of the epiphysis; and T2, dislocation with incomplete separation of the epiphysis.
