RESUMEN
Total elbow arthroplasty is effective for pain relief and the functional improvement of severe symptomatic hemophilic osteoproliferative arthropathy. Nevertheless, high complication rates have been reported. This report describes clinical results obtained at 30-month follow-up of total elbow arthroplasty in a hemophilic patient with severe flexion contracture. A 50-year-old patient with advanced left elbow hemophilic arthropathy underwent unlinked total elbow arthroplasty. He had sustained an intraoperative fracture of the medial part of a supracondylar humerus complication. To control perioperative bleeding, strict factor VIII replacement therapy was performed under the guidance of hematologists. The total elbow range of motion was 35° preoperatively, but it had improved to 110° postoperatively. The Patient-Rated Elbow Evaluation Japanese version score, which was 53.7 preoperatively, improved to 10.7 postoperatively. During the 30 months after operation, no complication occurred. Good clinical results have been obtained under close collaboration with hematologists and close patient adherence following treatment.
RESUMEN
Carpal joint osteoarthritis and the formation of bony irregularities of the carpal bone cause closed flexor tendon ruptures. This report describes a case of a flexor profundus tendon closed rupture of the little finger due to asymptomatic pisotriquetral osteoarthritis in a 73-year-old woman, which required differentiation from tendon rupture due to hamate bony irregularity due to bone erosion. Computed tomography showed cortical bone irregularities of the hamate and the narrowing of the pisotriquetral joint space, and a bony spur on the radial side of the pisiform. Intraoperative findings revealed the capsule of the pisotriquetral joint was torn on the radial side. Pisiform-hamate ligament disruption and the bony spur on the pisiform were found on this side. However, the flexor tendon floor on the hamate was intact. Surgical resection of the pisiform and a free tendon interposition graft for tendon rupture restored the good function of the little finger. Particular attention should be paid in making the diagnosis in cases with multiple possible triggers for closed flexor tendon rupture.
RESUMEN
BACKGROUND: Osteochondritis dissecans (OCD) of the humeral capitellum presents most typically in adolescent athletes who perform repetitive overhead activities. Earlier studies have demonstrated that conservative treatment of OCD is appropriate for patients with an open capitellar growth plate from the standpoint that spontaneous healing can be expected. CASE: A 12-year-old male baseball player with two years of experience with a local team participated in our medical check that included screening for capitellar OCD using ultrasonography. The subject experienced elbow pain when throwing, and ultrasonographic elbow examination indicated OCD of the capitellum, detected as irregularity of the subchondral bone of the capitellum. The initial radiograph, taken with the elbow at 45° of flexion, identified new bone formation in the lateral aspect of the OCD lesion; however the epiphyseal lines of the capitellum and lateral epicondyle were closed. We advised the patient to stop heavy use of the elbow, e.g., throwing and batting, and started conservative treatment in anticipation of spontaneous healing. Physiotherapy focusing on the shoulder girdle, core, and hip and lower limb stretches were performed to resolve general tightness. The OCD lesion had healed completely 12 months after the start of conservative treatment. DISCUSSION: Conservative treatment for young baseball players might be worth considering if lateral new bone formation within the OCD lesion is detected on radiographic findings, even if the epiphyseal lines of the capitellum and lateral epicondyle are closed.
RESUMEN
Cubital tunnel syndrome, the second-most common peripheral compression neuropathy, is associated with dynamic pressure in the cubital tunnel with the elbow flexion position. Medial elbow ganglion originated from the ulnohumeral joint causing cubital tunnel syndrome has been reported. This report describes the case of a 48-year-old man who developed numbness in his left ring and little finger after prolonged motorbike touring. He gradually showed decreased hand grip strength with medial elbow joint pain. Ultrasonography and magnetic resonance images revealed small occult ganglion at the medial side of elbow joint. Surgical resection of ganglion and ulnar nerve decompression relieved the ulnar neuropathy symptom. Prolonged motorbike riding while maintaining the elbow flexion position might exacerbate the symptom of cubital tunnel syndrome in patients with even a small space-occupying lesion such as the small occult ganglion.
