A scoring system to demonstrate the risk for bone injury in patients with clinically suspected or occult scaphoid fracture

Background: It is important to diagnose a scaphoid fracture accurately and start the correct treatment in the shortest time possible. However, the fracture of bone may not be visible on x-ray. In such cases, patients are clinically diagnosed with suspected or occult scaphoid fractures. The aim of this study was to define a scoring system based on physical examination to demonstrate the risk for bone injury in patients with clinically suspected and occult scaphoid fractures with negative radiographs and anatomical snuff box tenderness and to decrease the costs and workforce loss due to unnecessary treatment and magnetic resonance imaging (MRI). Materials and Methods: Patients were initially evaluated by the attendant orthopedic physician in the emergency service with X-ray of the wrist, and ten wrist physical examination techniques were used. The X-rays of patients were evaluated by three orthopedic surgeons. Finally sixty patients, who were diagnosed as having no fracture by all three orthopedic surgeon, were included in the study. The wrists of these patients were evaluated with MRI. Results: There were 46 male (77%) and 14 female (23%) patients with a mean age of 21.5 years (range 7–61 years). About 3.3% had triquetrum fracture, 15% had bone edema in the scaphoid and radius, 18.3% had distal radius fracture, 31.6% had scaphoid fracture, and 31.8% had no bone injury. A scoring system was also proposed. It can be predicted that in the physical examination of the wrist if the total score is higher than 6.5, the probability of fracture is 2.87 (positive likelihood ratio) fold compared to scores below 6.5. Conclusions: Proposal of this new scoring system was thought to be useful for predicting the risk for bone injury in patients with clinically suspected scaphoid fractures and making decision regarding therapeutic options.

Ultrasonographic comparison of bilateral patellar tendon dimensions in patients treated via intramedullary tibial nailing using a transpatellar approach

Objective One of the most common complications following intramedullary nailing of a tibial shaft fracture is anterior knee pain. The etiology of pain remains unclear. Patellar tendon entry point is the most suspected reason for anterior knee pain. This study, sonographically examined the patellar tendons of patients treated via intramedullary nailing. Methods Thirty-two patients with a tibial shaft fracture requiring intramedullary nailing via a transpatellar approach were included in the study. After all patients were grouped by reference to the presence of anterior knee pain, bilateral patellar tendon ultrasonography was performed. Results Thirty-two patients were included in the study. Patients were measured postop average in 38.3 months (10th months - 84th months). It was determined that 10 patients of total 32 (31.3%) had anterior knee pain. There were no statistically differences between study groups in the length of patellar tendon. In the painless group; patellar tendon was wider and thicker in the operated side than the non operated side. The mean differences in the thickness between operated side versus non – operated side of the painless group were 5.3 ± 1.8 in the operated side and 3.9 ± 1.4 in the non – operated side (p = 0.007 < 0.05). The corresponding values for width of the patellar tendon was 29.6 ± 3.3 in the operated side and 27.6 ± 3.8 in the non – operated side (p = 0.007 ˂ 0.05). As a result, there were no statistically significant differences between width and thickness of the patellar tendons in the painful group, on the contrary, in the painless group; patellar tendons were wider and thicker in the operated side than those in the non - operated side. Mean values for thickness of the operated and non-operated side were 5.9 ± 2.3 and 4.2 ± 2.0, respectively (p = 0.059 > 0.05). Mean values for width of the operated and non-operated side were 30.2 ± 4.5 and 28.5 ± 4.0, respectively (p = 0.103 > 0,05). Conclusion Based on the ultrasonographic investigation of their patellar tendons after intramedullary nailing of a tibial shaft fracture, in the painless patients group; the patellar tendon was wider and thicker in the operated side than the non – operated side, however, in the painful patients there were no statistically significant differences between this parameters. Although the number of patients was not sufficient to conclude precise relation between patellar tendon entry point and anterior knee pain, we determined that thicker and wider tendon might be less related to anterior knee pain. Level of evidence Level IV, therapeutic study.

Arthroscopic Technique for Treatment of Schatzker Type III Tibia Plateau Fractures Without Fluoroscopy

Accurate reduction and maintenance of the stability with correct implant positioning is critical for surgical treatment of tibial plateau fractures. Our technique includes an arthroscopic reduction and fixation of Schatzker type III tibial plateau fractures with a bulls-eye screw placement without fluoroscopy control. With the arthroscopic guidance, an anterior cruciate ligament drill guide is placed and a K-wire sent to the midpoint of the depressed fragment through the guide at a 40° angle to the coronal axis of the tibia. A tunnel is created with the drill over the K-wire. The depressed fragment is further augmented with gentle impacts over the K-wire. After arthroscopic reduction control, an appropriate-sized iliac graft is pushed until it is below the depressed fragment. The targeting device is adjusted at 130° so that it is parallel to the joint line and a K-wire sent through the device so that it would pass just below the graft. The graft is then supported with cannulated screws sent over the K-wire. This technique provides an arthroscopic reduction of the chondral surface and precise placement of the rafting screws without fluoroscopy.

Proximal Tibia Medial Biplanar Retrotubercle Open Wedge Osteotomy for Varus Knees with Medial Gonarthrosis

Objectives: The purpose of this study is to evaluate the early results of proximal tibia medial biplanar retrotubercle open wedge osteotomy for varus gonarthrosis and compare the results with the literatüre. Methods: The results of proximal tibia medial biplanar retrotubercle open wedge osteotomy for 23 knees of 22 patients with medial gonarthrosis were evaluated clinically and radiologically. Results: Twenty of the patients were female and two were male. Mean age of the patients was 56.24; mean boy mass index was 31.95 and preoperative HSS (Hospital for Special Surgery) score was 68.7. Mean tibiofemoral axis was 186.39° and mean Insall-Salvatti index value was 1.04 preoperatively. Mean follow up period was 30.19 months. Mean HSS score was 86.48, femorotibial anatomic axis angle was 175° and Insall-Salvati index value 1.06 during the last follow-up. The improvement of the HSS score and the femorotibial anatomic axis angle was statistically significant. However, the change in Insall Salvati index values was statistically insignificant. Nonfatal pulmonary embolus in 1 patient, and deep vein thrombosis that occured one year after the procedure in 1 patient, rhabdomyolysis in 1 patient and loss of correction (relapse) in 1 patient were encountered as complications. Conclusion: Our results show that proximal tibia medial biplanar retrotubercle open wedge osteotomy improves the frontal and sagittal plane deformities without changing the patellar tendon length. Hence, possible patellofemoral problems are prevented and the clinical results are improved.
