Vascular complications of tibial exostosis: A case of popliteal vein thrombosis.

Tibial exostosis, also known as osteochondroma, is a common benign bone tumor found predominantly in adolescents and young adults. Vascular complications associated with this tumor, such as arterial occlusion and pseudoaneurysm formation, are rare but can lead to significant morbidity if not promptly diagnosed and managed. We present a case of a 25-year-old patient who presented with thrombosis of the left popliteal vein and a painless swelling in the popliteal fossa. Radiographic and CT angiography revealed an exostosis on the proximal tibia causing arterial occlusion and venous compression. Surgical resection of the exostosis via a posterior knee approach resulted in successful resolution of symptoms and a favorable outcome at a 12-month follow-up. Histopathological examination confirmed the benign nature of the tumor with no evidence of malignant transformation. This case highlights the importance of prompt recognition and surgical intervention in managing vascular complications associated with tibial exostosis. A multidisciplinary approach involving orthopedic and vascular specialists is crucial for achieving optimal outcomes in such cases.

Our experience with the surgical management of lower cervical spine fractures: fifty case series.

PURPOSE: Trauma to the lower cervical spine is a serious lesion due to its neurological consequences which jeopardize the vital and functional prognosis. They constitute a public health problem due to their frequency and seriousness requiring rapid and adequate treatment. The aim of our study is to (1) describe the epidemiological, clinical, and radiological characteristics of lower cervical spine trauma patients; (2) support the therapeutic management of these patients and show our experience in surgery for lower cervical spine trauma; and (3) analyze the anatomical and functional results and discuss them with literature data. METHODS: This is a retrospective descriptive study of 50 patients with lower cervical spine trauma treated surgically over a period of five years from January 1, 2016, to December 2020. RESULTS: The average age of our patients was 34.5 years, with a sex ratio of 1.7. The etiologies are dominated by accidents on public roads (58%). They show neurological disorders such as spinal cord damage in 30% of cases and root damage in 20% of cases. The radiological assessment revealed eight tear drops, ten comminuted fractures, 12 severe sprains, 12 biarticular dislocations, six uniarticular dislocations, and two herniated discs. Treatment was surgical in all patients with an anterolateral approach and anterior arthrodesis. The evolution was favourable in 21 patients and stationary in 29 patients. CONCLUSION: Our study concluded that dislocations and fracture dislocations were the predominant type of injury in cases of AVP. Tetraplegia was mainly observed with uni- and biarticular dislocations. The variation in consolidation time was not correlated with trauma-to-surgery time. Better neurological recovery was observed with mild initial neurological damage than with initially severe damage. The appearance of an adjacent syndrome is less frequent with monosegmental arthrodesis than with multisegmental arthrodesis. Cage arthrodesis was an alternative to iliac harvesting with similar results.

Interest of longitudinal patellar tunnels in reconstructing chronic patellar tendon rupture with semitendinosus autograft: A case report.

Treatment of chronic patellar tendon ruptures represents a real challenge for orthopaedic surgeons. The superior patellar migration and the pathological aspect of the tendon are the two conditions that aggravate the situation. Several reconstruction methods have been described in the literature. Hamstring tendon augmentation using horizontal patellar tunnel is widely used in such cases. However, underuse of longitudinal patellar tunnels, although they reproduce the native footprint of the patellar tendon insertion, highlights a missed opportunity in chronic patellar tendon rupture reconstruction. In the current article, we describe a semitendinosus tendon autograft reconstruction technique where the patellar tunnels are drilled longitudinally instead of being drilled transversely from medial to lateral. At 34 months follow-up, our patient claimed full active knee mobility with good quadriceps strength. Reproducing the native footprint of the patellar tendon insertion, through longitudinal patellar tunnels, leads to optimal outcomes after chronic patellar tendon rupture reconstruction with Semitendinosus Autograft.

Clinical and radiographic outcomes after paediatric supracondylar humeral fractures treated with combined intramedullary and lateral wire fixation: our experience in fifty-one cases.

PURPOSE: Displaced supracondylar humerus fractures in children are known for their high rate of complications and require urgent surgical treatment. Basically, there are two methods of fracture fixation: the lateral pin technique and the crossed pin technique. However, the best technique remains debated. The aim of this study was to evaluate the clinical and radiographic outcomes of our method of fixation using combined intramedullary and lateral wires for treatment of displaced supracondylar humeral fractures in paediatric patients. METHOD: Fifty-one paediatric patients were treated for displaced supracondylar humeral fractures. The method of fracture fixation used consists of two Kirschner wires inserted one intramedullary and the other laterally. Clinical and radiographic outcomes were assessed at last follow-up. RESULTS: According to Gartland's classification, 17 fractures (33%) were type 2 and 34 (67%) were type 3. The mean follow-up period was 7.8 months. Functional outcome according to Flynn's criteria was satisfactory in all cases with 92% graded as excellent or good. Cosmetic outcome according to Flynn's criteria was satisfactory in all cases. Radiologically, at last follow-up, the mean Baumann angle was 69° (63-82°) and the mean lateral capitellohumeral angle was 41° (32-50°). CONCLUSION: Patients managed with combined intramedullary and lateral wires experience satisfactory results. Moreover, this technique, without risk for the ulnar nerve, can be interesting in the treatment of infrafossal fractures and fractures with anterior displacement.

High-pressure injection of paint into the hand: A small injury with serious consequences.

High-pressure injection injury to the hand is a rare but very serious clinical entity, considered by plastic and hand surgeons as a surgical emergency. Diagnosis of these injuries is frequently delayed due to the initial benign appearance of the wound and the lack of knowledge of the seriousness of this injury.

Intrapelvic migration of the lag screw in intramedullary nailing after intertrochanteric fracture fixation: A case report.

The expected number of hip fractures worldwide will rise from 1.7 million in 1990, to 6.3 million in 2050. In parallel, surgical complications are expected to increase. We describe a rare complication of intrapelvic migration of the lag screw from trochanteric nail in a 90-year-old woman.

False aneurysm in a Charcot foot: A case report.

Charcot foot or neurogenic osteoarthropathy is a serious complication of diabetic peripheral neuropathy. The association between false aneurysm and Charcot foot is yet uncommon and has not been reported through the literature. We describe a case of false aneurysm in a Charcot foot in a 55-year-old female patient.

[Predictive factors of aseptic loosening of cemented total hip prostheses]. / Facteurs prédictifs de descellement aseptique des prothèses totales cimentées de la hanche.

INTRODUCTION: Aseptic loosening is the main long-term complication and indicates total hip replacement failure. There are many and often intricate causes for aseptic loosening. Incorrect placement of the implants is the most incriminated factor. Other patient and implant related factors may also predispose to loosening but to various degrees. METHODS: We conducted a retrospective study of 64 cases with aseptic loosening of total hip prosthesis to individuate patient, implant type and surgical technique related factors leading to aseptic loosening and to provide recommendations to minimize this risk. RESULTS: This was an analytic retrospective study of 64 cases with aseptic loosening. The classification is that used by the French Society of Orthopedic Surgery and Traumatology. The average age of the patients at the time of the first arthroplasty was 40 years, 62 years at the time of loosening. Charnley stem was implanted in 55 cases, Muller stem in 9 cases. Acetabular component was well positioned in 69% of cases with an average inclination of 47.8 °. The stems were canal-filling in 86% of cases with Grade A cementation in 60% of cases. The mean time for loosening onset was 12 years. 72% of the prostheses had a survival longer than 10 years. Statistical analysis of the results identified risk factors leading to loosening, such as: age, body mass index, level of activity, cup inclination, femoral offset and cementation quality. CONCLUSION: A significant reduction in aseptic loosening of total hip prostheses may only be achieved by a more rigorous selection of patients, a greater security in the technical act and a better choice of the implant to be placed.

Primary Total Hip Replacement for a Femoral Neck Fracture in a Below-Knee Amputee.

INTRODUCTION: Femoral neck fracture on amputated limb is an uncommon lesion and challenging to manage. CASE REPORT: We report a case of a displaced neck fracture of the left femur in a 57-year-old female. She underwent at the age of the three a below-knee amputation of the ipsilateral limb for post traumatic ischemia. The fracture was managed by a total hip arthroplasty (THA), as a primary procedure. In this article we describe our experience of this unusual entity. CONCLUSION: Total hip arthroplasty in patients with lower limb amputation is a challenging and uncommon intervention, especially when it's a primary procedure. It may provide satisfactory outcome, and allows early rehabilitation.
