ABSTRACT
Dupuytren's disease is a chronic fibroproliferative disorder of the palmar fascia leading to progressive flexion contractures of the fingers, most often affecting the ring and little fingers. This condition predominantly affects men over the age of 50 and has a multifactorial etiology involving genetic predisposition and environmental risk factors such as manual labor and alcohol consumption [1, 2]. We report four clinical cases treated at the CHU de Rabat to illustrate the spectrum of presentations and therapeutic outcomes. All patients underwent surgical management with open fasciectomy. The procedures resulted in functional improvement without significant complications. A structured postoperative rehabilitation program was followed, contributing to satisfactory recovery. Non-surgical treatments such as collagenase injections may be effective in selected early-stage cases but were not applied in our series [3, 4]. The choice of therapy must be tailored according to disease severity and patient function. Surgical excision remains the standard in advanced stages, especially when deformities impair daily activities [2-5]. Follow-up is essential to monitor recurrence, which remains a challenge despite optimal management. This series emphasizes the importance of early diagnosis, patient education, and coordinated multidisciplinary care in optimizing outcomes.

ABSTRACT
Objective: To describe the diagnostic and therapeutic aspects of patellar tendon rupture and to report two cases treated by primary suture protected with a semitendinosus–gracilis (DIDT) autograft frame. Methods: Two patients with traumatic patellar tendon rupture underwent surgery using the same technique: primary repair and protective autologous DIDT frame. A literature review was performed to define the role of this technique. Results: Both patients regained full active extension and satisfactory knee mobility at 6 months, without major complications. Literature data report a success rate above 90% with this method. Conclusion: Patellar tendon repair protected by a DIDT frame is a reliable technique, allowing early mobilization and reducing the risk of rerupture.

ABSTRACT
Introduction: Recurrent patellofemoral instability is a frequent condition in young, active individuals. It results from anatomical and biomechanical factors such as trochlear dysplasia, an increased Q angle, or a lateralized tibial tubercle. Surgical treatment may involve tibial tubercle transposition (TTT) to realign the extensor apparatus and improve patellar tracking. Objective: To report the clinical and radiological outcomes of two patients treated with medial tibial tubercle transposition for recurrent patellar dislocations. Case Reports: Case 1: A 19-year-old female athlete with a 3-year history of recurrent right patellar dislocations. CT scan revealed a TT–TG (tibial tubercle–trochlear groove) distance of 24 mm. A medial tibial tubercle transposition using the Elmslie-Trillat technique was performed. Case 2: A 22-year-old male with bilateral subluxations and significant functional limitation. MRI showed type B trochlear dysplasia (Dejour classification) with a TT–TG distance of 22 mm. Anteromedial transposition combined with MPFL reconstruction was performed. Results: At 12 months postoperative, both patients showed clinical stability with significant improvement in Kujala scores (>85). No recurrence of dislocation was reported, and anterior knee pain had resolved. Conclusion: Tibial tubercle transposition is a reliable technique in the surgical management of recurrent patellar instability, particularly when TT–TG distance is increased. It may be combined with additional procedures depending on associated anatomical abnormalities.

ABSTRACT
Methicillin-resistant Staphylococcus aureus (MRSA) osteomyelitis is difficult to treat due to multidrug resistance, biofilm formation, and the need for prolonged intravenous therapy. This observational study involved 14 patients (6 chronic osteomyelitis, 8 septic non-union; age 14–78 years), all with MRSA sensitive only to vancomycin. Treatment included surgical debridement, high-dose local vancomycin via polymethylmethacrylate (PMMA) beads or coated nails, and a short intravenous vancomycin course with oral linezolid in selected cases. All patients achieved infection cure; fracture union occurred in all septic non-union cases, with no systemic toxicity. High local antibiotic delivery improved outcomes and reduced hospitalization, though PMMA required secondary removal. Dual mode vancomycin therapy appears effective for MRSA osteomyelitis and septic non-union, but larger controlled trials are needed for validation.

ABSTRACT
Giant cell tumour (GCT) of bone is a benign but locally aggressive neoplasm, frequently involving the epiphyseal region of long bones, particularly around the knee [1-3]. We report a case of GCT of the right proximal tibia in a skeletally mature patient who presented with pain and swelling. Radiological evaluation showed a well-defined expansile lytic lesion without evidence of metastasis [1-4]. The patient was managed with extended intralesional curettage using a high-speed burr, adjuvant chemical cauterisation, and defect reconstruction with polymethylmethacrylate (PMMA) bone cement [3, 4]. Post-operative recovery was uneventful, with excellent knee function and no recurrence at follow-up. Bone cement provided immediate stability, enabled early mobilisation, and facilitated detection of recurrence on imaging [4, 5]. This case highlights that extended curettage with adjuvant therapy and cement reconstruction is an effective joint-preserving technique for proximal tibial GCT, offering good functional outcomes and low recurrence rates [3–5].

ABSTRACT
Background: Transverse acetabular fractures often involve the weight-bearing dome of the acetabulum and require precise anatomical reduction for optimal functional recovery. Open reduction and internal fixation (ORIF) using the Kocher-Langenbeck approach remains a preferred method for managing such injuries. This study aimed to evaluate the functional outcomes following ORIF of transverse acetabular fractures using this posterior approach. Methods: This prospective observational study was conducted in the Department of Orthopaedic Surgery at Dhaka Medical College Hospital over 24 months from July 2017 to June 2019. A total of 25 patients aged 21–80 years with radiologically confirmed transverse or associated acetabular fractures were included. All underwent ORIF through the Kocher-Langenbeck approach within three weeks of injury. Functional outcomes were assessed using the Merle d’Aubigné and Postel scoring system at six months postoperatively. Results: The mean age of patients was 36.2 ± 14.12 years, with most (76.0%) between 20–40 years. Anatomical reduction was achieved in 80.0% of cases. At six months, 40.0% of patients had excellent, 20.0% good, 4.0% fair, and 36.0% poor outcomes. Overall, 76.0% had satisfactory outcomes. Pain-free status was observed in 76.0%, normal walking in 76.0%, and 95%–100% hip range of motion in 60.0% of patients. Functional outcome showed a significant distribution difference (p = 0.021), though not significantly associated with reduction quality (p > 0.05). Conclusion: ORIF through the Kocher-Langenbeck approach provides favorable functional outcomes in the majority of patients with transverse acetabular fractures.

ABSTRACT
This study examines the effects of diet and physical activity on the well-being of older people in Abidjan, by comparing institutional norms and real-life experiences. The aim is to analyse how these practices influence the physical, psychological and social health of older people, in a context of changing diets and unequal access to sports facilities. The triangulated qualitative approach involves semi-structured interviews with senior citizens from a variety of backgrounds, ethnographic observations in sociable spaces (markets, sports clubs, health centres) and an analysis of institutional discourse on active ageing. The results show that while certain dietary and sporting practices enhance autonomy and socialisation, economic constraints, cultural perceptions and infrastructure deficits limit their adoption. The discussion highlights the tension between globalised prescriptions and local roots. In conclusion, it appears essential to adapt public policies to the realities of the Ivory Coast in order to promote inclusive active ageing.
