Clinical and radiological evaluation of surgical management in olecranon fracture-dislocations.

PURPOSE: The treatment of olecranon fracture-dislocations (OFDs) remains challenging. OFDs are often misdiagnosed as Monteggia lesions, and the real frequency is actually higher. However, studies on OFDs are limited. This study aimed to report on the surgical management of OFDs and to highlight the importance of three-dimensional computed tomography (3D CT) evaluation in the treatment of OFDs. MATERIALS AND METHODS: The study participants included 18 patients (11 men, 7 women, mean age 44 years (range 24-78) with OFDs. Each patient's medical records, radiographs, and 3D CT scans were reviewed for demographics, injury details, operative findings, and information about radiological and functional outcomes. The patients were divided into 2 groups according to the direction of the dislocation: the posterior dislocation group (group 1, 7 patients) and anterior dislocation group (group 2, 11 patients). The clinical evaluation was performed according to Broberg-Morrey and the American Shoulder and Elbow Surgeons-Elbow (ASES-E) scoring systems. RESULTS: The mean follow-up period was 39 months (range 25-62 months). The Broberg-Morrey results were excellent in 4, good in 9, fair in 3, and poor in 2 patients. The mean ASES-E score was 84.83 (range 48-100) points. There were signs of ulna-humeral arthrosis in 5 elbows. Arthrosis was graded as grade 1, grade 2, and grade 3 in 3, 1, and 1 elbows, respectively. Partial sensory recovery was observed in one patient with postoperative ulnar neuropathy at the last follow-up visit. CONCLUSIONS: OFDs are complex injuries of the proximal ulna and may involve the radial head, coronoid process, and lateral collateral ligament. The effective treatment of OFDs begins with the proper identification of the injury with 3D CT. A secure fixation including the coronoid process is mandatory for the elbow joint stability. Insufficient restoration of the trochlear notch may lead to problems with loss of motion and arthrosis. Although an application of a pre-contoured locking anatomical olecranon plate can simplify the fixation procedure in most cases, the surgeons' equipment should also include radial head implant, coronoid plates, headless screws, small cannulated screw system, suture anchors, fluoroscopy, and articulated external fixator.

Factors influencing the functional outcomes of tibia plateau fractures after surgical fixation.

AIMS: The aim of this study is to assess the functional and radiological outcomes of 52 surgically treated tibial plateau fractures and to determine the factors affecting functional outcomes. SUBJECTS AND METHODS: A total of 52 patients who were operated between 2007 and 2014 due to tibial plateau fractures were retrospectively reviewed. The Knee Society Score (KSS) was used for the functional outcome assessment. The Kellgren-Lawrence radiological evaluation score was used for the relationship between postoperative trauma and osteoarthritis in the last follow-up. RESULTS: Patients' mean age was 47.7 years (range, 14-84 years). The immobilization period was 4.2 weeks (range, 0-8 weeks), the full weightbearing time was 3.3 months (range, 1.5-5 months), and the follow-up time was 47 months (range, 17-102 months). Patients' mean KSS was 84.3 (range, 40-100). According to the Kellgren-Lawrence classification, 26 patients had grade 0, 11 patients had grade 1, 8 patients had grade 2, 5 patients had grade 3, and 2 patients had grade 4 postoperative osteoarthritis. CONCLUSION: Use of graft if there is collapse on joint surface, early knee motion, and early started full weightbearing after surgical fixation of tibial plateau fracture is essential for successful outcome. Findings of osteoarthritis on X-rays are not related to poor functional outcome at the mid- to long-term follow-up of surgical treated tibial plateau fractured patients.

Open reduction in pilon variant posterior malleolar fractures: Radiological and clinical evaluation.

BACKGROUND: Pilon variant posterior malleolar (PVPM) fractures significantly disrupt joint congruency and cause tibiotalar instability. They are often underestimated and inadequately treated. PURPOSE: This study assessed the outcomes of surgical treatment of this subtype of malleolar fracture, and examined the importance of computed tomography (CT) in diagnosis and surgical treatment. MATERIAL AND METHODS: CT images and radiographs of 67 patients with trimalleolar ankle fractures were retrospectively analyzed. Fourteen patients (6 women and 8 men) were studied. The mean age was 37.7 (range, 21-58) years, and mean follow-up period was 17.1 (range, 12-24) months. All patients underwent open reduction. Reconstruction of the joint surface was assessed with postoperative CT images. The outcomes were assessed with the American Academy of Orthopaedic Surgeons (AAOS) and Osteoarthritis (OA) scoring systems. RESULTS: The ratio of PVPM fractures to trimalleolar ankle fractures was 20.1%. Postoperative CT images demonstrated that anatomic reconstruction was achieved in 11 patients. The mean AAOS scores were 85.6 in Type 1 and 81.1 in Type 2 cases. The mean OA scores were 1 in Type 1 and 1.1 in Type 2 cases (P>0.05). The only statistically significant difference between the 2 groups was in osteochondral impaction (P<0.05). CONCLUSION: CT imaging is essential for the accurate diagnosis and management of PVPM fractures. Posteromedial and posterolateral incisions enable direct exposure, and therefore facilitate joint surface reconstruction. LEVEL OF EVIDENCE: Level IV. Retrospective study.
