ABSTRACT
Background@#The treatment of distal humerus fractures is often challenging in osteoporotic elderly patients. Total elbow arthroplasty (TEA) is a salvage option for non-reconstructable fractures. The aim of this systematic review was to evaluate the clinical evidence for primary TEA in patients with acute distal humeral fractures. @*Methods@#Literatures were searched through PubMed, Ovid/Medline, Cochrane, Google Scholar, and Embase databases with the keywords, “distal humerus fracture,” “total elbow arthroplasty,” and “outcome” according to the MeSH (Medical Subject Headings) index for English-language studies published from April 2009 to April 2019. We performed a systematic review using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. @*Results@#Ten articles with a total of 269 patients were included in the review. The Bryan-Morrey approach was the most common surgical approach (33.7%) with triceps reflecting (42%) for triceps tendon management. The most common implant design used was the Coonrad-Morrey system (83%). The mean postoperative motion arc was 102.3° for flexion-extension and 145.8° for pronation-supination. The average functional outcome score was 89.5 with Mayo Elbow Performance Score (MEPS). An excellent MEPS was found in studies with less than 7 days of average time from injury to surgery. The overall complication rate was 21.5%. @*Conclusions@#The current review showed favorable outcome of primary linked TEA for acute distal humerus fractures. Despite the promising functional outcomes, the complication rate was still considerably high. This systematic review will give surgeons help in explaining to patients regarding the expected outcome after primary TEA for acute distal humerus fractures.
ABSTRACT
Heterotopic ossification is formation of bone in atypical extra-skeletal tissues and usually occurs spontaneously or following neurologic injury with unknown cause. We report a 46-year-old female with right shoulder pain and restricted range of motion (ROM) for 3 months without history of trauma. Magnetic resonance imaging (MRI) showed a lesion within the rotator cuff supraglenoid. Excisional biopsy from a previous institution revealed a heterotopic ossificans (HO ). Following repeat MRI and bone scan, histopathology from arthroscopic resection confirmed an HO. The patient demonstrated improved pain and ROM at follow-up. Idiopathic HO rarely occurs in the shoulder joint, and resection of HO should be delayed until maturation of the lesion to avoid recurrence. The current case showed that arthroscopic HO resection provides an excellent surgical view to ensure complete lesion removal and minimize soft tissue damage at the supraglenoid area. Furthermore, the minimally invasive procedure of arthroscopy may reduce rehabilitation time and facilitate early return to work.
ABSTRACT
PURPOSE: To identify the structural integrity of the healing site after medial open wedge high tibial osteotomy (MOWHTO) in patients with a posterior root tear of the medial meniscus (PRTMM) and chondral lesion by second-look arthroscopy and to determine the clinical and radiological findings. MATERIALS AND METHODS: From August 2010 to June 2016, 52 consecutive patients underwent MOWHTO and arthroscopic examination without a chondral resurfacing procedure and meniscal treatment for PRTMM. Twenty-four patients were available for second-look arthroscopic evaluation. The mean follow-up period was 19.5 months (range, 5 to 46 months). Clinical evaluation was based on the Lysholm knee scores and Hospital for Special Surgery (HSS) scores. RESULTS: There were 5 lax healing, 6 scar tissue, 13 failed healing of PRTMM. Definite change of chondral lesion was not observed. The Kellgren-Lawrence grade did not improve according to the follow-up plain radiograph. The mean Lysholm score improved from 34.7 preoperatively to 77.1 at the last follow-up, and the mean HSS score significantly increased from 36.5 to 82.4. CONCLUSIONS: This study revealed a low rate of healing potency of PRTMM and chondral lesion after MOWHTO without any attempt for meniscal treatment or chondral resurfacing. The cartilage and healing status of PRTMM was not associated with improved clinical outcomes and radiological findings.

This paper reports a case of a 21-year-old male patient who complained of intermittent pain and snapping at 110° of flexion in his left elbow joint. Magnetic resonance imaging revealed a band-like low signal intensity in front of the radiohumeral joint. An ultrasound was conducted to check its association with the symptoms. Observations of a high echo escaping from the radiohumeral joint at the point when snapping occurred indicated noted that the hypertrophic plica was a cause of the snapping. The hypertrophic plica removed arthroscopically, and the results were good for up to 6 months after surgery. If snapping is observed in the elbow joint, it will be necessary to consider the symptoms from the hypertrophic plica, although rare, and ultrasound might be an effective tool for a differential diagnosis.
