“…14 However, different morphologies of the radial head and neck result in ineffective congruency of plates; this leads to poor reconstruction of the radial head, elbow stiffness, and poor reduction. 15,16 In our study, plate fixation had a higher complication rate due to non-union, displacement, and hetertrophic ossification.…”

“…They are also of the opinion that osteosynthesis of radial head and neck fractures should be done in safe zone, where a plate can be securely applied without risking the proximal radioulnar joint. [20] In our study, we also looked for prevalence of types of curvature at the head and neck zone and we classified the curvature as flat or low concave. Also, in our study, both flat and low concave were equal in frequency, i.e.…”

R adial head and neck fractures constitute 1.7-5.4% of all fractures. Radial head fractures alone constitute one-third of all elbow fractures and about 20% of all elbow trauma cases.[1] An appreciation of the part played by radial head in the overall stability of elbow and forearm has encouraged several investigators to recommend conservation of radial head, either by operative fixation or by prosthetic replacement.Distal radius fractures comprise 8-15% of all upper limb fractures. So, information of normal values of distal Background: Knowledge of the size and shape of radial head is essential for construction of radial head prosthesis. Further, the measurements of bicipital tuberosity and its angular relationship to radial head are significant in surgical techniques, like in the reconstruction of biceps tendon. Even the morphometry of the distal radius is significant in numerous clinical orthopedic situations such as reduction of distal radius fractures and in the design of distal radius prosthesis. So, the aim of the study was to determine the morphometric parameters of proximal and distal radius in dry adult Indian radius. Methods:Fifty intact adult Indian radius (right = 23, left = 27) were chosen, and the various parameters of proximal and distal ends of radius were studied. Student's t-test was done to correlate all these parameters on the right and left sides. Results:The mean length of radius, height of head at medial and lateral ends, head anteroposterior and transverse diameter, head thickness at ventral, dorsal, and lateral ends were 23.5, 0.90, 0.75, 1.91, 1.85, 0.42, 0.32, and 0.30 cm, respectively. The mean depth of articular facet, length of neck, proximal and distal neck diameter, width and length of bicipital tuberosity, and radial circumference at bicipital tuberosity were 0.19, 1.19, 1.36, 1.31, 1.23, 1.97, and 4.54 cm, respectively. The mean length of styloid process, oblique and transverse width of lower end, anteroposterior diameter of lower end, and angle of radial inclination were 0.98cm, 2. 81cm, 2.59cm, 1.86cm, and 25.05º, respectively. Conclusion: This study will be useful for orthopedic surgeons in making prosthesis for the proximal and distal ends of radius. (Biomed J 2015;38:323-328)

“…Furthermore, qualitative evaluation was used in some studies. In their studies, Giannicola et al [22,23] evaluated the congruency between an anatomic plate and proximal radius on cadaveric bones by two independent observers and congruence was classified as good, moderate or poor. In this study, the volume of free space between the plate and bone was used as a criteria.…”

ÖZAmaç: Bu çalışmada iki anatomik distal femur plağının kadavra femurlarıyla uyumluluğu araştırıldı ve mevcut plakların her femura en iyi şekilde uyup uymadığı gösterildi. Gereç ve yöntemler: Gövdesinde beş, yedi ve dokuz deliği olan iki farklı plak seti 62 kadavra femuruna uygulandı. Plakların tüm iç yüzeyleri seramik çamuruyla sıvandı, sonra plaklar iki adet kendinden kilitli naylon kablo bağı kullanılarak kemiklere sabitlendi. Plak ve kemik arasında sıkıştırılan seramik çamurunun hacmi hesaplanarak nicel uyum parametresi olarak kullanıldı. Her plağın verileri ayrı ayrı analiz edildi. Bulgular: Double Medical Technology Incorporated TM plakları kullanıldığında, plak ile kemik arasındaki hacim ortalamaları beş, yedi ve dokuz delikli plaklarda sırasıyla 8.4 mL (dağılım, 5-14 mL), 10.0 mL (dağılım, 6-17 mL) ve 13.1 mL (dağılım, 7-25 mL) olarak hesaplandı. Zimmer Biomet Incorporated TM plakları kullanıldığında, hacim ortalamaları beş, yedi ve dokuz delikli plaklarda sırasıyla 10.5 mL (dağılım, 6-21 mL), 12.7 mL (dağılım, 7-22 mL) ve 16.3 mL (dağılım, 8-30 mL) idi. Her grup içinde, ölçümler femur uzunluğu ile pozitif olarak anlamlı şekilde bağıntılı idi. Sonuç: Mevcut distal femur plağı implant setleri kullanılarak her femurda en iyi uyum elde edilemeyebilir. Bu nedenle, implant setlerinde ilave boyutlarda plaklar sağlanmalıdır.Anahtar sözcükler: Kadavra kuru femur kemiği, kilitli plakların uygunluğu, distal femur plağı, uyum değerlendirme parametresi, plak kemik uyumu; önceden şekillendirilmiş plak uyumu, nicel uyum parametresi. ABSTRACTObjectives: This study aims to investigate the fitness of two anatomic distal femoral plates with cadaveric femurs and to show whether current plates optimally match each femur. Materials and methods: Two different sets of plates with five, seven and nine shaft holes were applicated on 62 cadaveric femurs. Ball clay was molded onto the entire inner surfaces of the plates and then the plates were fixed to the bones using two self-locking nylon cable zip ties. The volume of ball clay sandwiched in between the plate and bone was calculated and used as a quantitative fit parameter. Data of each plate were analyzed separately. Results: Using Double Medical Technology Incorporated TM plates, the mean plate to bone volumes were calculated as 8.4 mL (range, 5-14 mL), 10.0 mL (range, 6-17 mL), and 13.1 mL (range, 7-25 mL) in five, seven and nine-hole plates, respectively. Using Zimmer Biomet Incorporated TM plates, the mean volumes were 10.5 mL (range, 6-21 mL), 12.7 mL (range, 7-22 mL) and 16.3 mL (range, 8-30 mL) in five, seven and nine-hole plates, respectively. Within each group, the measurements were significantly correlated positively with femoral length. Conclusion: Optimal fit may not be achieved in each femur using current distal femoral plate implant sets. Thus additional sizes of plates should be supplied in the implant sets.Keywords: Cadaveric dry femur bone, congruency of locking plates, distal femur plate, fit assessment parameter, plate bone fit, precontoured plate fit, quanti...
