SUMMARYObjective: The geometry of the proximal femur has gained very much attention in the last decade. Many radiological measures have been introduced to help radiologists and orthopaedic surgeons to evaluate surgeries, diagnose diseases and plan for surgical interventions. The main purpose of this study was to assess the validity of a novel radiological land marks and angles to help in Dynamic Hip screw (DHS) application surgery in the proximal femur. Method: 200 true hip anteroposterior radiographs were obtained for patients between ages 50 to 80 years. We have developed the lesser trochanteric fovea capitis angle (LTFCA) and the lesser trochanteric lateral cortex angle (LTLFCA). Patients were divided into two groups, the male group (n=100) and the female group (n=100). The LTFCA + LTLFCA were assessed in the left and right hips in both genders. Results: In male population, the average LTFCA + LTLFCA values for the right and left hip joints were (133.2°±5.27, 134.5°±4.92) respectively. There was no statistical difference between both sides, p= 0.74. Whereas in female population, the average LTFCA + LTLFCA values for the right and left hip joints were (134.8°±6.13, 135.6°±5.45) respectively. No statistical significance was detected between the two sides, p=0.37. Conclusions: The LTFCA is an easy method that can facilitate trustable radiological land marks for surgeons for proper DHS insertion. Further studies should be conducted to evaluate the sensitivity and specificity of the lesser trochanteric fovea capitis angle (LTFCA) and its validity in proximal femoral surgery. Keywords : Proximal femoral geometry; dynamic hip screw; lesser trochanteric fovea capitis angle ÖZET Amaç: Proksimal femur geometrisine olan ilgi son on yılda oldukça artmıştır. Hastalıklara tanı koymak, yapılacak cerrahiyi planlamak, yapılan ameliyatları değerlendirmek ve radyologlara ve ortopedistlere yardımcı olmak gayesi ile birçok radyolojik ölçüm yöntemi bildirildi. Proksimal femurda dinamik kalça vidası (DHS) cerrahi uygulamasına yardımcı yeni radyolojik işaret ve açıların geçerliliğini değerlendirmek bu çalışmanın ana amacıdır. Yöntem: Yaşları 50 ile 80 yaş arası hastalardan çekilen 200 true kalça AP radyografisi çalışmaya alındı. Küçük trochanter fovea kapitis açısını (LTFCA) ve küçük trochanter lateral korteks açısını (LTLFCA) geliştirdik. Erkekler (n=100) ve kadınlar (n=100) olarak hastalar iki guruba ayrıldı. LTFCA + LTLFCA her iki cinste sağ ve sol kalçada ayrı ayrı değerlendirildi. Bulgular: Erkek topluluğunda ortalama LTFCA + LTLFCA değerleri sağ kalçada 133.2°±5.27, sol kalçada 134.5°±4.92 idi ve her iki taraf arasında istatistiki fark bulunmadı (p= 0.74). Kadın topluluğunda ortalama LTFCA + LTLFCA değerleri sağ kalçada 134.8°±6.13, sol kalçada 135.6°±5.45 idi ve her iki taraf arasında istatistiki fark bulunmadı (p= 0.37). Sonuç: Küçük trochanter fovea kapitis açısı (LTFCA) uygun pozisyonda DHS çakılabilmesini kolaylaştıran güvenilir ve kolay bir yöntemdir. LTFCA nın duyarlılık ve özgüllüğünü ve proksimal femur cerrahisindeki ...

“…Variable radiological measures have been introduced to help radiologists and orthopedic surgeons to diagnose diseases, evaluate surgeries, and plan for surgical interventions (2)(3)(4). By introduction of picture archiving and communication systems (PACS) which became widespread and the standard radiological viewing tool in many orthopedic clinics, radiologists and orthopedic surgeons became more able to measure angles and distances even in a more precise manner (5,6).…”

Background: Many studies in the literature focused on the proximal geometry of the femur using cadaveric samples, X-rays or computed tomography, demonstrated substantial differences in the proximal femoral geometry in different patient groups. Many radiological parameters have been introduced in the literature to aid in diagnosis and surgical interventions. Objectives: We aimed to assess the diameter of the femoral head fovea capitis in both genders with different age groups and to record their variant configurations. Patients and Methods: Six-hundred true pelvis anteroposterior radiographs of patients were divided into three different age groups.

“…15,16 Many studies have correlated the Manchester scale system with variant foot angles in HV deformity, including the intermetatarsal and metatarsophalangeal angles. 12,13 However, it is strange not to find a well-structured study in the literature focusing the impact of the medial cuneiform bone variant measures (lateral tilt, the first metatarsocuneiform slope angle (MCSA) and the first metatarsocuneiform angle (MCA)) on the HV different clinical severity using the Manchester scale.…”

Purpose: The aetiology of hallux valgus (HV) is multifactorial in nature. The first metatarsocuneiform joint obliquity is a well-known factor in the development of the deformity. The purpose of this study is to assess the correlation of different medial cuneiform radiological measures on the severity of HV. Methods: Full weight-bearing anteroposterior views of 152 feet with different clinical severity are divided into four groups: without deformity and with mild, moderate and severe deformities. Three medial cuneiform angles were assessed, namely, the first metatarsocuneiform angle (MCA), the first metatarsocuneiform slope angle (MCSA) and the medial cuneiform lateral tilt angle (MCLTA and 58.78 + 6.25 , respectively. Statistical significances were detected between groups (1, 2), (1, 3) and (1, 4) with p values of 0.026, 0.018 and 0.001, respectively. Conclusions: Increasing the medial cuneiform lateral tilt increases the first metatarsocuneiform articulation obliquity demonstrated by the increase in the first MCSA which in term enhances the progression of varus deformity of the first metatarsal bone explained by the increase in the first MCA.
