Ulnar shortening after TFCC suture repair of Palmer type 1B lesions.
The objective of this study was to determine functional and subjective outcomes of an ulnar shortening procedure elected by patients who experienced persistent ulno-carpal symptoms following arthroscopic suture repair of a Palmer type 1B lesion. All patients had a dynamic ulna positive variance. ⋯ Patients who have a dynamic ulna positive variance and experience persistent ulno-carpal symptoms following arthroscopic suture repair of a Palmer type 1B lesion, benefit from an ulnar shortening procedure. Shortening the ulna can improve these patients' symptoms of pain, range of motion, and grip strength.

Case ReportsFracture of the tibial bone block after posterior cruciate ligament allograft reconstruction using double cross pins.
We report the fracture of the tibial bone block after posterior cruciate ligament reconstruction using double cross pins for bone block fixation in the postoperative period. The possible reasons include the size of bone block,direction of cross pin or the quality of bone block. This case emphasizes the biomechanical properties and failure of modes of double cross pin.

Intra-articular glenohumeral injections have an important role for therapeutic benefit and diagnostic information. Therefore, it is very important that the injected material should reach its desired target. This study assessed the accuracy of an anterior intra-articular injection in fresh cadavers. ⋯ Based on our cadaveric study, an unassisted anterior injection to the glenohumeral joint could be accurately placed.

Case ReportsVentricular tachycardia during arthroscopic shoulder surgery: a report of two cases.
We routinely have performed arthroscopic shoulder surgery under general anesthesia in the beach chair position using epinephrine (0.33 mg/L) saline irrigation. At a 2-week interval, two patients, a 19-year-old man scheduled to undergo an arthroscopic Bankart repair for left traumatic anterior instability and a 49-year-old woman scheduled for an arthroscopic rotator cuff repair for a left rotator cuff tear, were resuscitated by chest compression and defibrillation due to a sudden developed cardiogenic shock following ventricular tachycardia at the time of arthroscopic shoulder surgery. They were transferred to the intensive care unit because their emergent echocardiogram showed significantly decreased cardiac functions. ⋯ In addition, according to our observation of epinephrine flow patterns, it was more likely that highly concentrated epinephrine was rapidly infused into the body. This complication is very rare. However, thorough understanding of the side effects and their development of epinephrine during arthroscopic shoulder surgery should neither be overemphasized nor disregarded.

Arthroscopic locking plate removal after proximal humeral fractures.
The incidence of proximal humeral fractures increases. The locking plate osteosynthesis is a standard procedure to treat displaced proximal humeral fractures. In the mostly affected elderly patients with an osteoporotic bone structure, complication rate is still high. ⋯ But also younger patients often request for hardware removal. The open implant removal with a subacromial and subdeltoideal arthrolysis is an extensive secondary surgery for the patients. We present a new technique to remove a locking plate from the proximal humerus arthroscopically with all advantages of the minimally invasive surgery, and the possibility to treat concomitant intraarticular pathologies parallelly.
