The patient was an 18-year-old collegiate baseball pitcher who injured his right throwing elbow during an overhead slider pitch. As a part of a study, preinjury ultrasound images of the throwing arm were obtained 2 weeks prior to the injury. One day postinjury, repeat ultrasound imaging of the medial elbow was performed. The attending team physician ordered a magnetic resonance arthrogram 2 days after injury, which confirmed the presence of a complete tear of the ulnar collateral ligament.

BACKGROUND: Little is known about the anatomical variations of the trochlear notch angle, nor do we know whether the cartilaginous layer modifies the trochlear bony contour. Our aim was to assess the variability of the bony and cartilaginous trochlear notch angles. MATERIALS AND METHODS: We assessed 78 healthy elbows (39 patients, 19 females and 20 males) with a mean age of 28 years (range 21-32). High-definition MRI coronal scans at the level of the flexion-extension axis were performed...

BACKGROUND: The posterior approaches to the elbow are considered as to allow an excellent joint exposure for total elbow arthroplasty. One complication that is well recognized is the insufficiency of the extensor mechanism in particular with the patients with poor tendon quality as in the rheumatoid diseases. The purpose of this paper is to present a new triceps-splitting exposure for total elbow arthroplasty used in rheumatoid patients with their preliminary results. METHODS: Fifteen consecutive patients with rheumatoid disease at grades III to V of the Larsen grading scale underwent total elbow replacement using the new triceps-splitting exposure called anconeus-triceps lateral flap and it preserves the integrity of the medial proper triceps tendon...

Maternal and progeny diets supplemented with 2 sources of trace mineral (TM) were evaluated for effects on the size and severity of osteochondrosis (OC) lesions in progeny produced by 64 Landrace × Large White sows. At breeding, sows were randomly assigned to maternal diets (gestation and lactation) consisting 1 of 2 TM treatments. One treatment consisted of inorganic TM (ITM) with ZnO, MnSO, and CuSO at concentrations to provide 150, 50, and 16.5 mg/kg diet of Zn, Mn, and Cu, respectively. The other treatment consisted of the same ITM concentrations plus an additional 50, 20, and 10 mg/kg diet of Zn, Mn, and Cu, respectively, supplied by a blend of AA-complexed TM (CTM) using Availa Sow...

BACKGROUND: Critically ill patients frequently suffer muscle weakness whilst in critical care. Ultrasound can reliably track loss of muscle size, but also quantifies the arrangement of the muscle fascicles, known as the muscle architecture. We sought to measure both pennation angle and fascicle length, as well as tracking changes in muscle thickness in a population of critically ill patients. METHODS: On days 1, 5 and 10 after admission to critical care, muscle thickness was measured in ventilated critically ill patients using bedside ultrasound...

REVIEW

Medial elbow injuries in the throwing athlete are common and increasing in frequency. They occur due to repetitive supraphysiologic forces acting on the elbow during the overhead throw. Overuse and inadequate rest are salient risk factors for injury. Most athletes improve substantially with rest and nonoperative treatment, although some athletes may require surgical intervention to return to play. Because of advances in conservative and surgical treatments, outcomes after medial elbow injury have improved over time...

INTRODUCTION: Ulnar neuropathy at the elbow (UNE) is a common peripheral compression neuropathy and in most cases occurs at 2 sites, the retroepicondylar groove or the cubital tunnel. With regard to a potential therapeutic approach with perineural corticosteroid injection the aim of this study was to evaluate the distribution of injection fluid applied at a standard site. METHODS: We performed ultrasound-guided (US-guided) perineural injections to the ulnar nerve halfway between the olecranon and the medial epicondyle in 21 upper limbs from 11 non-embalmed cadavers...

INTRODUCTION: Recurrent complete ulnar nerve dislocation has been perceived as a risk factor for development of ulnar neuropathy at the elbow (UNE). However, the role of dislocation in the pathogenesis of UNE remains uncertain. METHODS: We studied 133 patients with complete ulnar nerve dislocation to determine if this condition is a risk factor for UNE. In all, the nerve was palpated as it rolled over the medial epicondyle during elbow flexion. RESULTS: Of 56 elbows with unilateral dislocation UNE localized contralaterally in 17 (30...

BACKGROUND: Ulnar neuropathy at the elbow (UNE) is the second most common entrapment neuropathy after carpal tunnel syndrome. Treatment may be conservative or surgical, but optimal management remains controversial. This is an update of a review first published in 2010 and previously updated in 2012. OBJECTIVES: To determine the effectiveness and safety of conservative and surgical treatment in ulnar neuropathy at the elbow (UNE). We intended to test whether:- surgical treatment is effective in reducing symptoms and signs and in increasing nerve function;- conservative treatment is effective in reducing symptoms and signs and in increasing nerve function;- it is possible to identify the best treatment on the basis of clinical, neurophysiological, or nerve imaging assessment...

Any kind of anatomical variation whether encountered during cadaveric dissections or routine clinical or surgical procedures needs to be reported and taken into account. This can be quite helpful in planning surgeries accordingly and avoid disastrous complications. During routine cadaveric dissection, authors found a superficial course of arteries of the arm as well as the forearm, unilaterally in one cadaver. In this case, there were two brachial arteries - superficial and deep. Superficial brachial artery terminated into superficial radial and superficial ulnar artery...

In adults, the oblique cord or chorda obliqua separates the origins of the flexor pollicis longus (FPL) and flexor digitorum profundus (FDP) muscles from the supinator muscle and elbow joint. This study examined the topographic anatomy of the oblique cord and related muscles in fetuses. Semiserial sections of five mid-term fetuses of gestational age (GA) 14-16 weeks and 12 late-stage fetuses of GA 28-30 weeks were histologically examined and three forearms at GA 30 weeks were macroscopically evaluated. Late-stage fetuses showed a fascial structure between the supinator and FDP muscles...

OBJECTIVE: To validate the findings of preoperative motor short-segment nerve conduction studies (SSNCSs) by intraoperative SSNCSs in patients with cubital tunnel syndrome. METHODS: We prospectively recruited patients with ulnar neuropathy at the elbow (UNE) localized distal to the medial epicondyle (ME). Preoperatively, motor SSNCSs and ultrasonography (US) were performed. Immediately after surgical dissection of the humeroulnar aponeurotic arcade (HUA), intraoperative near-nerve motor SSNCSs were performed, and compared to preoperative findings...

Shuai Chen, Hede Yan, Wei Wang, Mei Zhang, Kevin A Hildebrand, Cun-Yi Fan
BACKGROUND: Because medial elbow stability is essential for stiff elbow release, surgical techniques have been reported for reconstructing medial elbow stability. However, medial collateral ligament (MCL) defects, caused by inevitable detachment and resection performed for complete release, make the reconstruction more challenging. To our knowledge, no study has evaluated the outcomes after using a flexor-pronator fascia patch in medial elbow reconstruction for open release of stiff elbows...

AIMS: Cubitus varus is the most common late complication of a supracondylar fracture of the humerus in children. Correction can be performed using one of a number of techniques of osteotomy but each has disadvantages. We describe a new technique for correcting post-traumatic cubitus varus using a lateral closing wedge isosceles triangular osteotomy. PATIENTS AND METHODS: A lateral closing wedge isosceles triangular osteotomy was performed in 25 patients (15 male and ten female with a mean age of 9...

Congenital brachial artery true aneurysms are exceedingly rare. Most are pseudoaneurysms secondary to trauma or infection. We report a boy aged 2 years who presented with painless, pulsatile swelling on the medial aspect of the right arm, 4 cm above the elbow joint that had been present since birth. Spiral CT angiography showed a fusiform aneurysm of the distal right brachial artery with a peripheral crescent-shaped thrombus. Distal arteries were normally opacified. There was no evidence of abnormal dilation or stenosis in any other artery...

The purpose of this study was to evaluate for ulnar nerve instability following incrementally widened in situ decompression. A standard release of the ulnar nerve was performed in 16 cadaveric elbows, extending from 7cm distal to the medial epicondyle, and then released proximally for a total of 10 cm in 2-cm increments. Eight of the 16 elbows (50%) displayed subluxation of the ulnar nerve following complete in situ decompression. The rate of subluxation was found to increase with increasing length of proximal decompression...

Consensus opinion is that active movement of the elbow is a priority in the surgical treatment of total brachial plexus injuries. But the indications and neurotization techniques used to restore motor function of the hand are the subject of discussion. The aim of this retrospective study was to evaluate, in adult patients with complete post-traumatic paralysis of the brachial plexus, the functional results of neurotization of four intercostal nerves on the musculocutaneous nerve and grafting of the C5 root by one strand on the nerve to the long head of triceps and three strands on the medial component of the median nerve...

The aim of our study is to evaluate the clinical and radiologic outcomes in patients with terrible triad injury, who underwent surgical treatment with or without the medial collateral ligament (MCL) repair. Fourteen patients who underwent surgery with a minimum of 12-month follow-up (mean, 17 months) were reviewed. Based on the systematic treatment protocol, radial head fracture, lateral collateral ligament, and coracoid fracture were treated. Subsequently, torn MCL was repaired in 7 patients, whereas in the remaining 7 patients, the MCL was not treated...

BACKGROUND: Many techniques have been described to relieve the compression and reduce subluxation of the ulnar nerve following surgery. The subfascial anterior transposition of the ulnar nerve (SfATUN) is one described technique, but involves a long scar, risk of injury to the medial antebrachial cutaneous nerve, and possible nerve ischemia from anterior transposition. We assessed a more refined approach of endoscopy-assisted SfATUN for the treatment of cubital tunnel syndrome. METHODS: A consecutive case series of 21 patients (15 males and 6 females) with evidence of nerve subluxation after ulnar nerve decompression were operated using an endoscopy-assisted SfATUN...
