Background:Intra-articular fractures of the distal part of the triquetrum within the pisotriquetral joint are uncommon, and can be associated with tears of the dorsal carpal ligaments, pisiform subluxation and/or FCU dislocation. Their diagnosis is difficult and requires a high clinical suspicion and a proper radiological examination including oblique wrist x-rays, computed tomography and MRI scan. These fractures can be delayed diagnosed due to late presentation thus leading to painful nonunion, persistent instability and late pisotriquetral arthritis.Case Report:We present a case of a 40-year-old male who complained about ulnarsided wrist pain after a fall on his extended wrist during bicycling. The diagnosis of triquetrum fracture was suspected on clinical examination and confirmed using standard and oblique radiographs and CT scan evaluation. He was immobilized in a short-arm cast for 6 weeks followed by a progressive return to wrist motion and subsequent strengthening for another 5 weeks. He reported complete resolution of pain and excellent wrist motion and function one year after the injury, demonstrating a Mayo score of 100.Conclusion:Isolated intra-articular fractures of the triquetrum within the pisotriquetral joint are rare injuries and may constitute a subcategory of body fractures other than the dorsal cortical (chip), main body and volar lip avulsion fractures. Early clinical suspicion and proper imagine can lead to a successful outcome.
Hybrid internal and external fixation combined with tibiofemoral extension of the fixation is an attractive treatment option for complex tibial plateau fractures.
Background:Solitary fractures of the body of the hamate are rare. Their diagnosis is difficult and requires a high clinical suspicion and a proper radiological examination.Case report:We present a case of a 36-year-old male patient who sustained an intraarticular fracture of the body of the hamate along with dorsal dislocation of the 4th and 5th metacarpals on his right dominant hand. Through a dorsal surgical approach, he underwent ORIF of the hamate with screws and stabilization of the dislocated 4th and 5th metacarpals with KW. At his last follow-up appointment, 18 months postoperatively, he had no pain, almost full range of motion on his fingers and a Mayo Wrist score of 90 points.Conclusions:Hamate fractures are rare entities that can cause significant patient morbidity if not recognized and treated appropriately.
The anterolateral complex (ALC) of the knee has gained increased interest over the last decades due to the high revision rates of anterior cruciate ligament reconstruction (ACLR). Furthermore, in patients with an ACL tear, the injury of at least one of the ALC’s anatomic structures has been shown to be significantly higher, thus affecting its secondary stabilizing role at the knee joint. As such, ACLR augmentation techniques, that embrace the ALC, have been proposed recently, and indications for these procedures are still evolving. This review aims to present and discuss the most current anatomical, biomechanical, and imaging data, current reconstruction techniques, and the clinical results of ALC reconstruction.
Patient: Male, 62-year-old
Final Diagnosis: Arthroplasty • knee • posterior dislocation • prolonged flection contracture • septic loosening
Symptoms: Knee joint pain
Medication: —
Clinical Procedure: —
Specialty: Orthopedics and Traumatology
Objective:
Patient complains/malpractice
Background:
Chronic posterior knee dislocation after total knee arthroplasty (TKA) is a rare but serious complication, especially when it coexists with septic implant loosening, flexion contracture, and extensive comorbidities. Although the severity is comparable to that in the native knee dislocation, there are few reports in the literature. When TKA dislocation is complicated with infection, bone defect, and patient’s comorbidity, treatment becomes even more difficult. For these complex complications, in order to provide stable and mobile knees, constrained total knee prostheses are used.
Case Report:
We present the case of a 63-year-old, non-ambulatory man, with mental retardation and multiple comorbidities, who had a 9-year history of neglected posterior TKA dislocation, which later became complicated with septic loosening and productive fistula for 4 years.
The patient required use of a wheel-chair for several years, was obese with a body mass index (BMI) of 34.3, and the affected knee was in a prolonged flexion contracture at 90°. The posterior TKA dislocation was later infected by
Staphylococcus hominis
and
Staphylococcus epidermidis
. He was successfully treated with two-stage revision surgery and managed to become ambulatory after 6 years of requiring use of a wheel-chair.
Conclusions:
Neglected posterior dislocation of TKA is a rare and potentially limp-causing complication, especially when accompanied with chronic infection, implant loosening, severe bone loss, flexion contracture, and extensive comorbidities. A multidisciplinary approach with careful preoperative planning, exceptional surgical technique, and prolonged supervised physiotherapy are the keystones for a successful outcome.
Patient: Male, 51-year-old
Final Diagnosis: Intraosseous ganglion cyst
Symptoms: Discomfort • pain
Medication: —
Clinical Procedure: Athroscopy • bone graft
Specialty: Orthopedics and Traumatology
Objective:
Rare disease
Background:
This article presents a rare case of 2 separate intraosseous ganglion cysts of the talus in a 51-year-old man, treated with a unique technique of precise lesion targeting to avoid extensive bone loss and minimize articular chondral injury of the talus.
Case Report:
Two separate intraosseous ganglion cysts of the talus were diagnosed in a 51-year-old man with chronic ankle pain. A single straight-line incision with an entry point through the talonavicular joint was created to spare the precarious blood supply of the talus network. The 2 distinct subchondral lesions were approached under fluoroscopic control for curettage and autologous bone grafting using the anterior cruciate ligament tibial guide in a pair-of-compasses fashion. In almost 5 years of follow-up the patient has been asymptomatic. Magnetic resonance imaging has revealed no signs of degenerative changes in the ankle or the talonavicular joint, and the intraosseous edema has almost disappeared.
Conclusions:
To the best of our knowledge, this case is the first report of 2 distinct intraosseous ganglion cysts of the talus. We recommend the precise targeting technique used in our case for treating intraosseous talar lesions with intact articular cartilage.
