Toric IOLs are an effective means for treating both regular corneal-based astigmatism and cataract in both PK and non-PK patient groups. Analysis of results revealed similar trends for both groups in all areas except postoperative BUVA. Further studies are planned to better understand why PK patient's BUVA did not fit the trend of the other results.

Treatment of distal tibial fractures is technically challenging. The purpose of this study was to evaluate the use of distally locked retrograde Ender nail fixation of axially stable fibular fractures associated with these distal tibia fractures. During a 4-year span, we treated 23 fibular fractures, associated with either distal tibial metaphyseal or articular fractures, with a retrograde 3.5-mm Ender nail. The surgical protocol along with radiographic and clinical outcomes is presented. Using this technique, we have achieved excellent fibular union with minimal complications.

This study suggests a weightbearing radiograph of an isolated lateral malleolus fracture cannot determine deltoid ligament integrity and thus need for fibular operative fixation.

Syndrome of the trephined (SoT) is a severe complication following decompressive craniectomy resulting in neurological decline which can progress to aphasia, catatonia, and even death. While cranioplasty can reverse neurological symptoms of SoT, awareness of SoT is poor outside of the neurosurgery community. The authors performed a systematic review of the literature on SoT with a focus on reconstructive implications. Search terms “syndrome of the trephined” and “sunken flap syndrome” were applied to PubMed to identify primary studies through October 2021. Full-text review yielded 11 articles discussing SoT and reconstructive techniques or implications with 56 patients undergoing cranial reconstruction. Average age of the patients was 41.8±9.5 years. Sixty-three percent of the patients were male. The most common indication for craniectomy was traumatic brain injury (43%), followed by tumor resection (23%), intracerebral hemorrhage (11%), and aneurysmal subarachnoid hemorrhage (2%). Patients most commonly suffered from motor deficits (52%), decreased wakefulness (30%), depression or anxiety (21%), speech deficits (16%), headache (16%), and cognitive difficulties (2%). Time until presentation of symptoms following decompression was 4.4±8.9 months. Patients typically underwent cranioplasty with polyetheretherketone (48%), titanium mesh (21%), split thickness calvarial bone (16%), full thickness calvarial bone (14%), or split thickness rib graft (4%). Eight percent of patients required free tissue transfer for soft tissue coverage. Traumatic Brain Injury (TBI) was a risk factor for development of SoT when adjusting for age and sex (odds ratio: 8.2, 95% confidence interval: 1.2–8.9). No difference significant difference was observed between length until initial improvement of neurological symptoms following autologous versus allograft reconstruction (P=0.47). SoT can be a neurologically devastating complication of decompressive craniectomy which can resolve following urgent cranioplasty. Familiarity with this syndrome and its reconstructive implications is critical for the plastic surgery provider, who may be called upon to assist with these urgent cases.

Purpose: To review the histological findings in the lacrimal sac and nasal mucosa from patients with sarcoidosis undergoing external lacrimal drainage surgery. Methods: All patients undergoing external dacryocystorhinostomy at Moorfields Eye Hospital with a known history of sarcoidosis had biopsies taken from the lacrimal sac and/or nasal mucosa during surgery. These patients were identified from databases at Moorfields Eye Hospital and the Institute of Ophthalmology, and their clinical notes were reviewed retrospectively for intraoperative findings with a view to identifying common trends. The histological findings of each biopsy were reviewed and classified as showing granulomas, nongranulomatous inflammation, or nonspecific fibrosis. Results: Forty patients (29 females; 72%) were known to have systemic sarcoidosis prior to surgery, and they underwent 60 external dacryocystorhinostomies. Paired histological samples were available from 49/60 (82%) procedures, nasal biopsies alone in 3 dacryocystorhinostomies (5%), and solely lacrimal sac biopsies in 8 (13%). The main site of systemic sarcoidosis was pulmonary involvement (19 patients; 48%). Recorded operative findings included 9 large lacrimal sac mucoceles (29%), a “thick” (26%) or “inflamed” (9.7%) lacrimal sac mucosa, and “thick” (36%) or “friable” (32%) nasal mucosa. Noncaseating granulomas were identified in 34/57 (60%) sacs, and 45/52 (87%) nasal tissues—this being in 31/49 (63%) of paired tissues. Chronic inflammation, without granulomas, was present in 20/57 (35%) lacrimal sacs but only in 5/52 (9.6%) of nasal biopsies. Conclusions: In patients with sarcoidosis undergoing external dacryocystorhinostomy, the characteristic histological feature—noncaseating granulomas—is present in most patients’ lacrimal sac mucosa and in almost all of their nasal mucosae. The lacrimal sac and nasal mucosa often appears abnormal—thickened or friable—during surgery.

Reconstruction of full thickness, total upper eyelid defects represents a significant challenge in terms of recreating an upper eyelid which has acceptable cosmesis and a degree of dynamic function. Options include bridging, eyelid-sharing techniques (e.g., Cutler-Beard), or nonbridging techniques such as an anterior lamella-based flap combined with a posterior lamella free graft or a "sandwich flap." The success of these techniques depends on the size of the defect, postoperative cosmesis and whether or not the upper eyelid still has a degree of dynamic function to avoid ptosis and exposure keratopathy. The authors present an innervated frontalis turnover flap supporting anterior and posterior lamella grafts as a reconstructive solution for an extensive upper eyelid defect. This technique is cosmetically acceptable, preserves local tissues, and maintains a degree of dynamic function, which keeps the patient's eye comfortable and does not adversely affect visual acuity.

Chronic pain conditions are some of the most challenging problems upper-extremity surgeons face and often require a multimodal approach including neuromodulation. Peripheral nerve stimulation (PNS) is one of these modalities, delivering electrical stimulation to peripheral axons to modulate the spinal cord and block out nociceptive signals from the extremity. This blockade leads to long-lasting effects in both the peripheral and central nervous systems. Not only does PNS decrease peripheral pain signals but it also decreases the peripheral inflammatory response and assists with central nervous system plasticity for long-term pain control. Although PNS was initially developed in the 1960s, it has been underrepresented in the literature largely due to the advent of spinal cord stimulation and the lack of Food and Drug Administrationeapproved hardware for PNS. However, for upper-extremity pain, PNS provides notable benefits over spinal cord stimulation devices, as PNS allows for safer, more specific, and often more effective pain control. As clinicians attempt to limit narcotic use, therapies such as PNS have been revisited and are gaining popularity. We present a narrative review of PNS; discuss its mechanism of action, indications, and surgical technique; and provide a summary of the available literature for the upper-extremity surgeon. Peripheral nerve stimulation offers a solution for chronic, debilitating pain recalcitrant to other treatment modalities.
