Osteosynthesis of an intertrochanteric fracture on osteopetrosis A case report.

INTRODUCTION: Osteopetrosis is a rare hereditary disease that can be transmitted in an autosomal recessive or autosomal dominant. CASE REPORT: Here, we report a case of trochanteric fracture in an 18-year-old boy with an anatomical plate. At the last follow-up, 24 months after surgery, the fracture had healed well, and the patient was not restricted in his activities. DISCUSSION: Osteopetrosis is a rare bone disease that is mainly caused by osteoclast dysfunction. It results from a remodelling defect that leads to hypermineralization of the skeleton, resulting in bone fragility. Both surgical and nonsurgical management have advantages and disadvantages. Thus, open reduction and anatomic plate fixation remain effective management modalities for trochanteric fractures in osteopetrosis patients. CONCLUSION: For our patient and as described in the literature, the complication rate decreases as some principles are respected with better consolidation of the osteoporotic fracture.

Partial sterno-costo-claviculectomy for Ewing's sarcoma of the medial clavicle (case report).

INTRODUCTION: Primary clavicle tumors are uncommon and account for <1 % of primary bone tumors. The majority of primary clavicle tumors are malignant. Approximately 1.4 % of all cases of Ewing's sarcoma occur in the clavicle. CASE PRESENTATION: Here, we report the case of a patient diagnosed with Ewing's sarcoma who received neoadjuvant chemotherapy and had an important reduction in the tumoral volume; second, the patient had undergone partial resection of the medial clavicle, first rib, and the sternum. DISCUSSION: The survival rate of patients with nonmetastatic lesions is 56-79 %. The clavicle is connected to major anatomical structures, which makes surgery challenging. Even if there is little morbidity after resection, these studies did not show the superiority of reconstruction. CONCLUSION: The location of Ewing's sarcoma in our patient indicated that the surgical approach was needed for large resection. The functional outcomes were excellent, with no signs of recurrence at the 2-year follow-up.

Bifocal rupture of the patellar tendon in TKA: Case report and review of the literature.

INTRODUCTION AND IMPORTANCE: Rupture of the extensor apparatus is a serious complication that can occur in a prosthetic knee. Bifocal extensor ruptures are rare and even more uncommon in adults. CASE PRESENTATION: We report the case of an obese, diabetic, and hypertensive patient who underwent total knee arthroplasty two weeks previously and was admitted following a fall from her height for a rupture of the patellar tendon with release of the sutures. An investigation revealed bifocal avulsion of the patellar tendon from its patellar and tibial insertion. The patient was treated with double lacing and anchoring at the patellar and tibial levels with wire cerclage. CLINICAL DISCUSSION: Several factors contribute to tendon fragility: degenerative changes linked to age, general or local conditions, and surgical approaches for TKA. These abnormalities also affect the tendon's ability to heal and should suggest the inadequacy of simple repair without tendon augmentation using a plasty, an autograft, or an allograft. CONCLUSION: The prognosis for patients with extensor tendon ruptures in the TKA (total knee arthroplasty) remains unclear, and in our case, this was exacerbated by the delay between prosthesis insertion and the incident and by the open nature of the lesion.

Variant of the terrible triad of the elbow, a CASE report with a review of the literature.

INTRODUCTION: The terrible triad described by Hotchkiss in 1996 is a complex lesion of the elbow, following a trauma combining forced valgus and external rotation. It is a lesion that puts the elbow at risk of developing complications such as instability, stiffness, or synostosis of the proximal radio-cubital joint. CASE REPORT: We report the case of a patient who suffered a closed trauma to the right elbow following a fall onto the palm of the hand with a valgus lateral rotation mechanism. The lesion assessment showed a B2 fracture of the distal humerus (AO classification) with a line splitting the capitulum in the frontal plane, a type 3 coronoid process fracture (Morrey/Odriscoll classification), and a posterolateral elbow dislocation. The surgical treatment followed the same principles as for the terrible triad, with a reconstruction of the lateral column by osteosynthesis of the humeral palate, followed by an internal approach for osteosynthesis of the coronoid process, with the restoration of a stable elbow without laxity in the frontal plane. DISCUSSION: On the basis of the lesion mechanism, column theory, and the schematization of the constituent elements of elbow stability in a ring, certain lesions can be placed in the same box as the terrible triad of the elbow, which also complies with the same therapeutic implications. CONCLUSION: Our observation underlines the possibility of the existence of lesions other than those described by Hotchkiss, which would have the same consequences: an unstable elbow with the risk of evolving into chronic instability or stiffness and whose management accepts the same management.

Post-traumatic missing medial malleolus: case report with a one-year follow-up.

INTRODUCTION AND IMPORTANCE: Ankle fractures result from a wide variety of mechanisms the biomechanics of this articulation make any fracture altering the contact of the articulation surface lead to increased stresses and an inevitable evolution to tibiotalar arthritis. CASE PRESENTATION: We report the case of a 56-year-old patient admitted for open fracture dislocation of the ankle with a missing medial malleolus. He was treated by external fixation k-wiring and periosteal repair of the deltoid ligament. The one-year follow-up shows a good functional outcome with the patient's satisfaction. CLINICAL DISCUSSION: In ankle fractures, some authors report no need for fixation of the medial malleolus. Furthermore, the absence of the medial malleolus is not necessarily accompanied by instability of the ankle; however, it inevitably leads to ankle osteoarthritis. CONCLUSION: Our patient admitted for a bimalleolar fracture with missing medial malleolus, as described in the literature, had a favorable evolution with a functional score that was judged fair.
