Metastases to intramammary nodes have been shown to be an independent predictor of poor outcome in patients with breast cancer, such as axillary lymph node metastases. The detection and accurate characterization of these nodes preoperatively is thus crucial for the staging and planning of treatment for breast carcinoma, particularly in cases with axillary lymph node negative disease as it upgrades the disease staging. We herein report the first case where we detected an intra-mammary node on specimen MRI after the primary pathological gross specimen evaluation failed to detect the node.

STUDY DESIGN: A retrospective computed tomography (CT)-based morphometric study of 84 C1pedicles in an Indian population focusing on critical morphometric dimensions vis-a-vis C1 pedicle screw placement. PURPOSE: To determine the feasibility of C1 pedicle screw placement in an Indian population and propose a novel classification system for the same. OVERVIEW OF LITERATURE: At present, C1 pedicle screws are rarely used, and very few studies have focused on the feasibility of pedicle screw placement in terms of racial, gender, and ethnic variations in anatomical structures. There are no CT-based data on C1 pedicles that assess the feasibility of pedicle screw placement in the Indian population. METHODS: We measured C1 pedicle diameter on CT coronal scan images of 42 adult patients. Extramedullary height (EMH) and intramedullary height (IMH) were measured. We examined the differences between the right and left atlas pedicles and compared measures between males and females. These data were analyzed using significance tests. Based on the results, we propose a novel classification system, which we believe will help in determining the feasibility of C1 pedicle screw placement. RESULTS: Forty-two adult patients (84 pedicles) were examined. Average EMH and IMH were 4.48±0.91 and 0.86±0.77, respectively. Approximately, 32% of the C1 pedicles had bone thicknesses of <4 mm, 49% had IMH of <1 mm, and 38% had no pedicles. The average thickness in women was 4.21±0.93 mm, which was significantly thinner than that in men (4.73±0.81 mm, p=0.004). Right and left pedicles were not significantly different. CONCLUSIONS: Our data indicate that approximately one-third of the Indian population may not be suitable candidates for C1 pedicle screw placement. Caution should be exercised while placing type 1B and type 2 pedicles based on our proposed classification system.

BACKGROUND: To assess the functional and radiological outcomes of minimally invasive anterior bridge plating (ABP) for mid-shaft humerus fractures in patients predominantly involved in overhead activities (athletes and manual laborers). METHODS: Forty-eight patients fulfilling inclusion criteria were treated with ABP at a level-I trauma center using a 4.5-mm dynamic/locking compression plate and followed for a period of 1 year. Functional outcome was assessed using the Constant, Mayo elbow, and Disabilities of the Arm, Shoulder and Hand (DASH) scores. Range of motion (ROM), subjective strength, and radiographic union were assessed. A general satisfaction questionnaire was also administered. RESULTS: Most patients achieved excellent functional and radiological outcomes. ROM and strength of the shoulder girdle exhibited clinically nonsignificant loss as compared to the opposite side. The mean time for return to the original activities was 64 days (range, 36 to 182 days) and the mean time for confirmed radiographic union was 45 days (range, 34 to 180 days). The mean Constant, Mayo elbow, DASH scores were 95.73 ± 5.76 (range, 79 to 100), 95.94 ± 6.74 (range, 85 to 100), and 1.56 ± 3.15 (range, 0.0 to 14.0), respectively. The majority of patients (43 patients, 89.6%) who fell in the excellent or very good category according to our questionnaire were extremely satisfied. There were 2 cases (4.17%) of nonunion and 3 patients (6.25%) had to change/modify their original occupation. CONCLUSIONS: ABP is fundamentally different from traditional open posterior plating or conventional intramedullary nailing. It gives relative stability with union taking place by callus formation, and a longer plate on the tensile surface ensures that the humerus can withstand greater amount of rotational and bending stresses. The minimally invasive nature causes minimal soft tissue damage and, if done correctly, causes no damage to the vital structures in proximity. ABP for mid-shaft humerus fractures in patients predominantly engaged in overhead activities is a safe and effective treatment modality yielding high rates of union, excellent functional recovery, minimal biological disruption, better cosmesis, and superior satisfaction rates.

STUDY DESIGN: A retrospective computed tomography (CT)-based morphometric study of 82 occipital condyles in the Indian population, focusing on critical morphometric dimensions with relation to placing condylar screws. PURPOSE: This study focused on determining the feasibility of placing occipital condylar screws in an Indian population using CT anatomical morphometric data. OVERVIEW OF LITERATURE: The occipital condylar screw is a novel technique being explored as one of the options in occipitocervical stabilization. Sex and ethnic variations in anatomical structures may restrict the feasibility of this technique in some populations. To the best of our knowledge, there are no CT-based data on an Indian population that assess the feasibility of occipital condylar screws. METHODS: We measured the dimensions of 82 occipital condyles in 41 adults on coronal, sagittal, and axial reconstructed CT images. The differences were noted between the right and left sides and also between males and females. Statistical analysis was performed using the t-test, with a p-value of < 0.05 considered significant. RESULTS: Mean sagittal length and height were 17.2±1.7 mm and 9.1±1.5 mm, respectively. Mean condylar angle/screw angle was 38.0°±5.5° from midline, with mean condylar length and width of 19.6±2.6 mm and 9.5±1.0 mm, respectively. Average coronal height on the anterior and posterior hypoglossal canal was 10.8±1.4 mm and 9.0±1.4 mm, respectively. The values in females were significantly lower than those in males, except for screw angle and condylar width. Based on Lin et al.'s proposed criteria, eight of 82 condyles were not suitable for condylar screws. CONCLUSIONS: Preliminary CT morphometry data of the occipital condyle shows that condylar screws are anatomically feasible in a large portion of the Indian population. However, because a small number of population may not be suitable for this technique, meticulous study of preoperative anatomy using detailed CT data is advised.
