RESUMEN
Humeral head chondrolysis has been widely reported as a devastating complication after arthroscopic shoulder surgery; however little is known about post-arthroscopic humeral head osteonecrosis. We experienced a 66-year-old female patient with rapidly progressive osteonecrosis of the humeral head only seven months after arthroscopic Bankart and rotator cuff repair. The patient had no systemic risk factors for osteonecrosis. A satisfactory result was achieved with reverse total shoulder arthroplasty for severe humeral head destruction and an irreparable massive rotator cuff tear. Shoulder surgeons should be aware of such severe complication, perform routine radiographs, and pay close attention to the presence of constant pain or loss of motion after arthroscopic shoulder surgery.

PURPOSE: The purpose of this study was to evaluate the risks of undergoing intramedullary nailing with minimum surgical optimization (fast-track) for geriatric trochanter fracture due to fall from a standing height. MATERIALS AND METHODS: From May 2006 to August 2013, 48 fractures were enrolled in fast-track, and were an average age of patients was 77.6 years (range, 62-97 years). They underwent primary testing for anesthesia, including basic body fluid test, arterial blood, electrocardiography, and chest radiographs. The time from visit to surgery was 28.9 hours (range, 1-96 hours). RESULTS: During hospitalization, there was one case of stress-induced cardiac arrest; however, other complications, infection, and 30-day mortality did not occur. According to preoperative classic test, the average albumin was 3.45 g/dl, blood sugar, 169 mg/dl, blood urea nitrogen, 20.5 mg/dl, Cr, 1.5 mg/dl, Na, 135.3 mEq/L, and K, 4.21 mEq/L. The average PaCO2 of arterial blood was 37.6 mmHg. CONCLUSION: We found that the fast-track for trochanteric fracture due to slip-down was relatively safe, and could be considered as a therapeutic approach.

Pins and wires are still used frequently in surgeries of the shoulder; however, these can cause breakage or migration to surrounding tissues, leading to complications. We report on case of a patient with a neck mass who had a past history of pulmonary tuberculosis and distal clavicle fracture with internally fixated state. She was misdiagnosed as tuberculous cervical lymphadenopathy and treated for approximately one year, but was finally revealed as granulation tissue around the internally fixated distal clavicle fracture site, thus, mass excision and metal removal was performed. This case shows the importance of a proper selection device, internal fixation technique, duration, and close follow-up after the operation.

PURPOSE: The purpose of this cadaveric study was to evaluate the conformity of the anatomically preshaped proximal humerus internal locking plate system (PHILOS) to the humeri of the Korean and anatomical features of nine locking screws for the proximal humerus. MATERIALS AND METHODS: This study included 20 adult humeri (average length 30.2 mm) with no deformity or previous surgery. PHILOS was applied to the lateral surface of the proximal humerus according to the contour. Then, the distance from the outer surface of the plate to the greater tuberosity and bicipital groove was measured. After K-wires were passed through the proximal locking guide, the intra-osseous length of K-wire and the configuration of the K-wire exit were evaluated. RESULTS: The overall conformity of PHILOS was excellent at the lateral aspect of the proximal humerus. The tip of the plate had an average distance of 3.6 mm (range, 1.4-6.6 mm; standard deviation [SD], 1.27) from the greater tuberosity and 2.5 mm (range, 0.0-4.6 mm; SD, 1.24) at the bicipital groove and the average intra-osseous length of K-wire through the locking guide was 41.1 mm (range, 23.5-53.7 mm). K-wires were evenly penetrated through the humeral head. On H8 and H9, the bottom hole of PHILOS is closely located at the most inferior area of the humeral articular surface. The bicipital groove was pierced by K-wires of H5, which was the middle hole of PHILOS in four cases (20%). CONCLUSION: PHILOS had excellent conformity with the proximal humerus and K-wires through the locking guide were evenly penetrated through the humeral head. However, much care should be taken in piercing of the bicipital groove in H5.
