[Ab] Abstract:AIM OF SURGERY: Reconstruction of the most important ligamentous and osseus structures of the elbow after terrible triad injury via the radial head to the lateral collateral ligament complex (LCL) and if necessary beginning at the coronoid process. The aim is a stable concentrically guided elbow with early functional follow-up treatment. The approach depends on the intraoperatively tested stability. INDICATIONS: Osteoligamentous terrible triad injury pattern with or without subluxation position following reduction and temporary immobilization. CONTRAINDICATIONS: Inoperable due to comorbidities. Concentric elbow with radial head fracture without impairment of pronation/supination, coronoid fragment <50% and stable range of motion up to 30°. OPERATIVE TECHNIQUE: Lateral access according to Kaplan or Kocher in order to address the anterior capsule/coronoid tip. Stabilization of the radial head with mini fragment screws and plates or radial head prosthesis. Osseous reinsertion of the LCL at its origin with transosseous sutures/bone anchors on the radial epicondyle of the humerus. In cases of persisting instability (hanging arm test) treatment with lateral movement fixation and/or the medial collateral ligaments from medial. FOLLOW-UP TREATMENT: Immobilization in upper arm plaster cast in the first postoperative days, active assistive pain-adapted movement therapy in the cast from postoperative day 1 and after 6-8 weeks resistive therapy in the whole elbow. RESULTS: Control of 15 terrible triad patients (mean age 45.9 years, range 20-87 years) after 9.6 months (range 2.6-31.6 months), extent of movement flexion/extension 131/14/0°, pronation/supination 78/0/67°. Arthrolysis after an average of 38 weeks in 4 patients, signs of joint arthrosis in 8, heterotopic ossification in 7 and neuropathic complaints in the region of the ulnar nerve in 1 patient. Early functional therapy with reproducible results by stabilization of osteoligamentous structures.

[Ab] Abstract:BACKGROUND AND AIMS: Intra-operative identification and preservation of extraocular motor nerves is one of the main goals of surgeries for skull base tumours and this is done by monitoring the extraocular movement (EOM). Intra-operative electromyographic monitoring has been reported, but it is a complex and skilful process. Electrooculography (EOG) is a simple and reliable technique for monitoring EOMs. We aimed to assess the utility of EOG monitoring in preventing extraocular motor nerve dysfunction during skull base surgeries. METHODS: In this retrospective cohort study, intra-operative EOG recordings were obtained using disposable needle electrodes placed on the periorbital skin and the polarity of the waves noted for interpretation. Triggered as well as continuous EOG responses were recorded after monopolar electrode stimulation of cranial nerve (CN) during tumour removal which helped the surgeon with careful dissection and avoiding potential nerve injuries. RESULTS: Of the 11 cases monitored, oculomotor and abducent nerves were identified in all cases, but the trochlear nerve could not be definitively identified. Six patients had no pre- or post-operative extraocular motor nerve dysfunction. The other five patients had pre-existing deficits before surgery, which recovered completely in two, significantly in one, and did not improve in two patients at 3-6 months follow-up. CONCLUSIONS: EOG was found to be a simple and reliable method of monitoring extraocular motor nerves (CNs III and VI) intraoperatively.

[Ti] Title:Risk of Injury to the Dorsal Sensory Branch of the Ulnar Nerve With Percutaneous Pinning of Ulnar-Sided Structures.

[Ab] Abstract:PURPOSE: To assess the risk of injury to the dorsal sensory branch of the ulnar nerve (DSBUN) with percutaneous pinning of commonly stabilized ulnar-sided structures. METHODS: Eleven fresh-frozen cadaveric upper extremities were assessed. Percutaneous pinning of the fifth metacarpal base and neck, lunotriquetral joint, ulnar styloid, and distal radioulnar joint (DRUJ) with 1.4-mm Kirschner wires was performed under fluoroscopic guidance. Each specimen was then carefully dissected and the distance from each pin to the DSBUN was measured using a digital caliper. Direct injury to the DSBUN and pins found immediately adjacent to the nerve were recorded. RESULTS: Mean distance from the pin to the DSBUN at the fifth metacarpal neck was 5.0 ± 1.5 mm; fifth metacarpal base, 2.3 ± 2.2 mm; lunotriquetral joint, 1.8 ± 1.6 mm; ulnar styloid, 0.8 ± 1.1 mm; and DRUJ, 3.1 ± 0.9 mm. Two of 11 ulnar styloid pins and 1 of 11 lunotriquetral pin directly penetrated the DSBUN, whereas 4 of 11 ulnar styloid pins, 3 of 11 fifth metacarpal base pins, and 2 of 11 lunotriquetral pins were directly adjacent to the DSBUN. There was an increased overall risk of DSBUN injury (risk of direct injury and risk of adjacent pin) with pinning of the ulnar styloid compared with fifth metacarpal neck and DRUJ pinning. CONCLUSIONS: The current study demonstrates the risk of iatrogenic injury to the DSBUN with percutaneous pinning of the ulnar styloid, lunotriquetral joint, and fifth metacarpal base. CLINICAL RELEVANCE: We recommend identifying and protecting the nerve to mitigate the risk of iatrogenic injury when performing ulnar-sided pinning of structures from the ulnar styloid to the fifth metacarpal base.

[Ab] Abstract:BACKGROUND: The extensile extensor digitorum communis (EDC) splitting approach can access the ulnar coronoid process (UCP), which can be used to treat terrible triad injuries. The present study anatomically examined the extensile EDC splitting approach for exposing the UCP. METHODS: Twenty fresh frozen cadaveric upper limbs were dissected. The splitting length of the EDC and detachment length of the extensor carpi radialis brevis (ECRB)-extensor carpi radialis longus (ECRL)-brachioradialis (BR) origin were measured to expose the UCP. The distance between the most distal site of the EDC splitting and the point at which the posterior interosseous nerve (PIN) crosses the anterior aspect of the radial shaft, and the distance between the most proximal site of the ECRB-ECRL-BR origin detachment and the point at which the radial nerve crosses the anterior aspect of the humeral shaft were measured. RESULTS: The splitting length of the EDC was 45.4 ± 4.8 mm, the detachment length of the ECRB-ECRL-BR origin was 30.2 ± 4.7 mm, the distance between the distal site of the EDC splitting and PIN was 10.6 ± 6.1 mm (minimum distance, 1.1 mm), and the distance between the proximal site of the ECRB-ECRL-BR origin detachment and the radial nerve was 49.5 ± 9.7 mm (minimum distance, 31.7 mm). CONCLUSIONS: The extensile EDC splitting approach can sufficiently expose the UCP. However, splitting must be performed carefully because the most distal site of the EDC splitting is close to the point at which the PIN crosses the anterior aspect of the radial shaft (average distance, 10 mm; minimum distance, 1 mm).

[Ab] Abstract:The head and neck is anatomically complex, and several nerves are at risk during orthognathic operations. Some injuries to nerves are reported more commonly than others. To find out what consultant surgeons tell their patients about the prevalence of common nerve injuries before orthognathic operations, we did a postal survey of fellows of the British Association of Oral and Maxillofacial Surgeons (BAOMS). We also reviewed published papers to find out the reported incidence of injuries to cranial motor nerves during orthognathic operations. Only injuries to the facial nerve were commonly reported, and we found only case reports about injuries to the oculomotor, abducens, and trochlear nerves. The risk of temporary facial nerve palsy reported was 0.30/100 nerves (95% CI 0.23 to 0.50) and permanent facial nerve palsy was 0.06/100 nerves (95% CI 0.02 to 0.15).

[Ab] Abstract:Several surgical techniques and modifications for ulnar collateral ligament (UCL) reconstruction have been proposed since this procedure was first performed in 1974. The goal of these techniques has been restoration of stability to the medial elbow with minimal alteration to the surrounding anatomy. Outcome studies and systematic reviews on modified techniques for UCL reconstruction have shown a trend toward increased return to play in patients, particularly overhead athletes. Abandonment of flexor pronator mass detachment in favor of a muscle-splitting or muscle-elevating approach, minimal handling of the ulnar nerve, and the docking technique may result in improved outcomes and decreased complications without diminished performance. Several biomechanical studies have compared the structural properties of these techniques with those of the native UCL. However, a clear, concise surgical algorithm for UCL reconstruction is lacking. Additional studies that use sport-specific outcome measures and performance metrics may better demonstrate the true return to preinjury performance after UCL reconstruction in overhead athletes.

[Ab] Abstract:BACKGROUND: Despite an increase in the prevalence of medial ulnar collateral ligament (UCL) reconstruction of the elbow in professional baseball and popularity within the media, there are no population-based studies examining the incidence of UCL reconstruction. PURPOSE: To examine the epidemiological trends of UCL reconstruction on a statewide level over a 10-year period. The primary endpoint was the yearly rate of UCL reconstruction over time; secondary endpoints included patient demographics, institution volumes, and concomitant procedures on the ulnar nerve. STUDY DESIGN: Descriptive epidemiology study. METHODS: The New York Statewide Planning and Research Cooperative System (SPARCS) database contains records for each ambulatory discharge in New York State. This database was used to identify all UCL reconstructions in New York State from 2002 to 2011 using the outpatient CPT-4 (Current Procedural Terminology, 4th Revision) code. Assessed were patient age, sex, ethnicity, insurance status, and associated procedures, as well as hospital volume. RESULTS: There was a significant yearly increase in the number of UCL reconstructions (P < .001) performed in New York State from 2002 to 2011. The volume of UCL reconstructions increased by 193%, and the rate per 100,000 population tripled from 0.15 to 0.45. The mean ± SD age was 21.6 ± 8.89 years, and there was a significant trend for an increased frequency in UCL reconstruction in patients aged 17 to 18 and 19 to 20 years (P < .001). Male patients were 11.8 times more likely to have a UCL reconstruction than female patients (P < .001), and individuals with private insurance were 25 times more likely to have a UCL reconstruction than those with Medicaid (P = .0014). There was a 400% increase in concomitant ulnar nerve release/transposition performed over time in the study period, representing a significant increase in the frequency of ulnar nerve procedures at the time of UCL reconstruction (P < .001). CONCLUSION: The frequency of UCL reconstruction is steadily rising in New York State and becoming more common in adolescent athletes. Emphasis on public education on the risks of overuse throwing injuries and the importance of adhering to preventative guidelines is essential in youth baseball today.

[Ti] Title:Delayed Superior Orbital Fissure Syndrome After Reconstruction of Blowout Fracture.

[Ab] Abstract:The superior orbital fissure syndrome (SOFS) has been known to be a condition caused by impairment of the nerves that cross the superior orbital fissure. Traumatic SOFS is an uncommon complication which occurs usually within 48 hours after a facial injury. A 25-year-old male sustained facial trauma following an altercation. Clinical findings on presentation included swelling, ecchymosis, hyphema, subretinal hemorrhage, and mild extraocular movement limitation upon lateral gaze on his right eyelids. Facial computed tomography scan confirmed fractures of the medial walls of the right orbit and herniation of orbital soft tissue without the incarceration of medial rectus muscle. Ten days after the trauma, the operation was performed. On postoperative day 16, the patient showed ptosis of the right upper eyelid with a fixed pupil, and there was a hypoesthesia over the distribution of the right supraorbital and supratrochlear nerves. The authors diagnosed as a delayed SOFS and prescribed 4 mg of methylprednisolone q.i.d. for 30 days. After steroid therapy, extraocular movement limitations improved progressively. After 8 months, movement was completely restored. The authors experienced delayed SOFS on posttrauma day 27, and it was treated by steroid therapy. Surgical intervention is required when there is an evident etiology such as underlying hematoma or plate migration. If the reason is not clear like our case, steroid therapy can be considered as one of the options. Particularly, the authors should give special attention to the patient who has congenitally narrow superior orbital fissure, like Fujiwara et al suggested.

[Ab] Abstract:Distal humerus fractures are challenging injuries for the upper extremity surgeon. However, recent techniques in open reduction internal fixation have been powerful tools in getting positive outcomes. To get such results, the surgeon must be aware of how to properly use these techniques in their respective practices. The method of fixation depends on the fracture, taking the degree of comminution and the restoration of the columns and articular surface into account. This article helps surgeons understand the concepts behind open reduction internal fixation of the distal humerus and makes them aware of pitfalls that may lead to negative results.

[Ab] Abstract:Eye movement is controlled by ocular motor pathways that encompass supranuclear, nuclear, and infranuclear levels. Lesions affecting certain locations may produce localizing signs that help radiologists focus on specific anatomic regions. Some pathologic conditions, such as aneurysms and meningiomas, have unique imaging characteristics that may preclude unnecessary tissue biopsies. Some conditions are life threatening and require urgent or emergent imaging. MR imaging is the imaging of choice in evaluation of ocular motor palsy, with magnetic resonance angiography or computed tomography angiography indicated in cases of suspected aneurysms or neurovascular conflicts.
