A balloon was then used to pull the perforated sheath with the IVC filter into a larger sheath. After removing the Tuohy-Borst and Luer adapters on the perforated sheath, it was able to be internalised and removed via the femoral vein sheath.
The endovascular rescue technique described herein may prove useful to other practitioners encountering similar situations, and the complication shows areas of caution when using the loop-snare retrieval technique.

Ulnar nerve injury is the most common neurologic complication of elbow arthroscopy. The purpose of this cadaveric study was to quantify the ability of surgeons to locate the ulnar nerve behind the posteromedial capsule during elbow arthroscopy using sole arthroscopic vision.
Twenty-one surgeons were asked to pin the ulnar nerve at the medial gutter and the posteromedial compartment using arthroscopic visualization of the medial capsule only. Pinning of the ulnar nerve was performed from extra-articular. Then, the cadaveric specimens were dissected and the shortest distances between the pins and ulnar nerve measured.
Median pin-to-nerve distances at the medial gutter and posteromedial compartment were 0 mm (interquartile range , 0-3 mm) and 2 mm (IQR, 0-6 mm), respectively. The ulnar nerve was pinned by 11/21 surgeons (52%) at the medial gutter, and 7/21 surgeons (33%) at the posteromedial compartment. Three of 21 surgeons (14%) pinned the ulnar nerve at both the medial gutter and the posteromedial compartment. Surgeon’s experience and operation volume did not affect these outcomes (
> .05).
Surgeons’ ability to locate the ulnar nerve behind the posteromedial capsule using sole arthroscopic visualization, without external palpation, is poor. We recommend to proceed carefully when performing arthroscopic procedures in the posteromedial elbow, and identify and mobilize the ulnar nerve prior to any posteromedial capsular procedures.

Pitching induces elbow valgus stress, which can lead to an increase in medial elbow joint-space gapping when repeated. Previous basic research on the medial elbow joint shows that the contraction associated with gripping reduces medial elbow joint-space gapping. However, no studies have investigated the relationship between grip strength and increased medial elbow joint-space gapping during repetitive pitching. The purpose of this study was to investigate whether grip strength is related to medial elbow joint-space gapping during repetitive pitching. Our hypothesis was that increased grip strength would correlate with a reduction in medial elbow joint-space gapping.
A total of 25 high school baseball players participated in this study. Each subject pitched 100 times. The medial elbow joint-space gapping and grip strength were measured before and after pitching. Correlation analysis was used to identify the relationship between medial elbow joint-space gapping and grip strength.
Medial elbow joint-space t physical ability expressed by grip strength is not associated with preventing increases in medial elbow joint-space gapping during repetitive pitching. Further studies are required to investigate the stabilization mechanism of the medial elbow joint during pitching.
Hegemann disease and fishtail deformity are classified as growth disturbances in the physeal plate of the humeral trochlea. It is questionable if these 2 diseases should be considered as 2 distinct conditions. The aims of this study are to (1) point out similarities between both conditions, (2) discuss etiology, and (3) provide diagnostic tools.
In a multicenter prospective cohort study, 19 patients with growth disturbance of the humeral trochlea were included. Assessment consisted of a detailed history, physical examination, and standard radiographs in 2 directions. MK571 manufacturer The radiographs were evaluated for skeletal age, carrying angles, and trochlear notch angles. Statistical analysis was performed using Stata.
A total of 19 patients were included 2 males (11%) and 17 females (89%). The mean age of the patients was 12.8 years. In 17 patients (89%), a traumatic injury of the elbow was reported, before presentation. Decreased trochlear notch angle (<104°) was seen in 16 patients (84%). Accelerated closure of the growth plate of the affected elbow was seen in all skeletally immature patients.
The main risk factor for both Hegemann disease and fishtail deformity is an injury of the elbow with open growth plates. Imaging studies support the hypothesis that both diseases are likely to be a continuum of the same process. Therefore, we propose to use 1 nomenclature for this pathologic process post-traumatic disturbance of the epiphysis of the humeral trochlea.

Total anatomic and reverse shoulder prostheses are designed to match the dimensions of the native bony anatomy. Chinese and Japanese bony dimensions of the shoulder have been found to be different from that of the Caucasian population. We hypothesized that the geometric dimensions of the humeral head and glenoid in the Indian population would also be different from that of the Caucasian population.
Fifty patients underwent computerized tomographic scans of their normal shoulders. We calculated the superoinferior (SI) diameter of the humeral head, anteroposterior diameter of the humeral head, radius of curvature of the humeral head, humeral head retroversion, humeral head thickness, inclination angle, critical shoulder angle, greater tuberosity angle, glenoid width, glenoid length, radius of curvature of the glenoid, glenoid inclination angle, and glenoid version.
The radius of curvature of the humeral head averaged 22.9 ± 1.7 mm, the articular surface thickness 17.1 ± 1.6 mm, and the SI diameter 42.3 ± 3 mm.
