Neglected patellar tendon rupture in tibial tubercle avulsion fracture in an adolescent: A case report.

A rare childhood injury is a combined tibial tubercle fracture and patellar tendon rupture, and this condition necessitates an open surgical procedure to perform a stable fixation of the tubercle fragment and a successful patellar tendon repair. When a tibial tubercle fracture in the tibia is present alone, a high index of suspicion is required. In this article, we described a case of a male teen who suffered a neglected patellar tendon rupture following close reduction and fixation of a tibial tubercle fracture.

Early clinical results of the BOX ankle replacement are satisfactory: a multicenter feasibility study of 158 ankles.

A new design for a 3-part ankle replacement was developed in an effort to achieve compatibility with the naturally occurring ligaments of the ankle by allowing certain fibers to remain isometric during passive motion. In order to test the design concept clinically, 158 prostheses were implanted in 156 patients within a 9-center trial and were followed up for a mean of 17 (range 6 to 48) months. The mean age at the time of surgery was 60.5 (range 29.7 to 82.5) years. Outcome measures included the American Orthopaedic Foot & Ankle Surgery hindfoot-ankle score and range of motion measured on lateral radiographs of the ankle. The preoperative American Orthopaedic Foot & Ankle Surgery score of 36.3 rose to 74.6, 78.6, 76.4, and 79.0, respectively, at 12, 24, 36, and 48 months. A significant correlation between meniscal bearing movement on the tibial component (mean 3.3 mm; range 2 to 11 mm) and range of flexion at the replaced ankle (mean 26.5°; range 14° to 53°) was observed in radiograms at extreme flexions. Two (1.3%) revisions in the second and third postoperative years necessitated component removal (neither were for implant failure), and 7 (4.4%) further secondary operations were required. The results of this investigation demonstrated that non-anatomic-shaped talar and tibial components, with a fully conforming interposed meniscal bearing, can provide safety and efficacy in the short term, although a longer follow-up period is required to more thoroughly evaluate this ankle implant.

Advantages of preoperative planning using computed tomography scan for treatment of malleolar ankle fractures.

Malleolar ankle fractures have been classified using plain radiographs, and there is no consensus regarding the role of computed tomography (CT) scans in preoperative planning. We analyzed critical aspects, such as limits of standard radiographs, types of injury, classification methods and cost/benefit evaluations. CT scans allow a 3D analysis of the fracture to be obtained and consequently assess the indication for surgical procedure, surgical access and the type of fixation devices required. This exam is useful for detecting lesions that may go unnoticed on radiographs and will help surgeons to clarify the pathoanatomy of ankle fractures. According to Arbeitsgemeinschaft fur Osteosynthesefragen/ Orthopaedic Trauma Association (AO/OTA) classification, CT scan is recommended in medial malleolar fractures with vertical rim, type 44B fractures with posterior malleolar involvement and all type 44C fractures (according to AO/OTA). Also Tillaux-Chaput fractures (43-B1 according to AO/OTA), malleolar fractures in the presence of distal tibial fractures (43 according to AO/OTA) and distal tibia fractures in adolescents should be studied with CT scans.

The "Ball in Basket" Technique for Tibiotalocalcaneal Fusion.

Tibiotalocalcaneal arthrodesis (TTCA) in severe bone deficit represents a complex challenge for expert orthopedic surgeons also. This study aims to illustrate a surgical technique, defined as "ball in basket", that facilitates the fitting of the structural bone graft (femoral head from bone bank) and its placement, in order to fill the bone gap during instrumented arthrodesis. The proposed technique includes the preparation of the recipient bone surfaces with acetabular convex reamers and of concave reamers to shape the bone graft from bone bank. This preparation guarantees a maximum congruence of the bone surfaces and a greater stability of the bone graft during the placement of the fixation devices to optimize the bone fusion and to provide a good patient clinical outcome. The preliminary results obtained for two patients, initially presenting with severe anatomical deformity associated with severe bone gap, are described. Patients underwent clinical and radiographic follow-up evaluations (respectively at 4 and 30 months of follow-up) showing radiographic healing and good functional recovery. The results are encouraging, although long-term studies and a wider cohort of patients are necessary to consider this technique a reliable aid in case of severe bone deficit. (www.actabiomedica.it).

Two cases of neglected posterior fracture-dislocation of the shoulder with ipsilateral humeral shaft fracture.

Posterior shoulder fracture-dislocations are rare. A combination of this injury with ipsilateral humeral shaft fracture is an extremely rare event. We report two cases of posterior shoulder fracture-dislocation with ipsilateral fracture shaft of humerus treated in our department. We highlight the rarity of the condition and the potential risk of recognize only the shaft fracture. We emphasize the importance of complete physical and radiological examination (x-rays and CT scan) in such cases to ensure early detection and its subsequent surgical treatment.

Pedal ectrodactyly: a case report with a new surgical management.

A case report is presented regarding a patient with type IV bilateral ectrodactyly treated with a double surgical approach: in forefoot to correct the malformation and in rearfoot to prevent secondary deformity of the subtalar joint. The forefoot was enlarged and in particular the second and third rays were absent. There was also a metatarsus primus varus with interphalangeal hallux abductus. The second cuneiform bone was removed with a wedge resection of the midfoot. The reduction in transverse diameter of the forefoot was obtained by cerclage of the first and fourth metatarsal bones. For hallux valgus, a percutaneous distal osteotomy of the proximal phalanx was performed. Several months after the forefoot correction, subtalar joint pronation was noted secondary to the altered forefoot mechanics and was treated with a subtalar Arthroereisis. The contralateral foot was addressed using similar techniques, except all procedures were done in a single surgical session. A favorable outcome for the patient 1 year and 6 months after surgery seems to justify this approach.

Percutaneous drilling for chronic heel pain.

The authors report a retrospective study involving 25 feet in 21 patients who underwent percutaneous drilling for chronic heel pain. Patients with increased activity of the heel were considered for surgical treatment if there was increased uptake on the delayed bone scans. The average follow-up was 21 months (range, 6 to 30 months). All patients were treated in day surgery with local anesthesia. Three small holes were bored in the medial cortex of the calcaneus. Clinical evaluation of the parameters of pain, walking distance, fascial tenderness, paresthesias, and ankle and subtalar joint motion were evaluated preoperatively and at final follow-up. In 7 patients, repeat bone scans were performed and 6 patients had resolution of the abnormal uptake. In 81% of feet treated, there was a favorable outcome based on a subjective scoring scale. Using a visual analog pain scale, the preoperative pain level was 8.8 (range, 4 to 10), and at latest follow-up, it was 2.4 (range, 0 to 10). These results are comparable to other available surgical methods for the treatment of recalcitrant heel pain. Less predictable results were seen in patients with rheumatic and systemic pathologies and in those diagnosed with Haglund deformity. This technique appears to be effective in the relief of intraosseous congestion and bone-marrow edema.
