BACKGROUND: A small size and difficulties with shaping a medial femoral condyle corticocancellous bone flap are factors limiting its use. The goal of this study was to evaluate range of vascular supply to a medial femoral condyle corticocancellous bone flap to determine whether harvesting of larger flaps and performing a flap osteotomy would compromise the vasculature of a flap's bone. METHODS: Twenty-four limbs were dissected and medial femoral condyle corticocancellous bone flaps were harvested with skin paddles...

BACKGROUND: Complex surgery for appearance change is controversial. Correction of orbital hypertelorism risks diplopia and loss of stereopsis for aesthetic gain. The risk-to-benefit ratio remains ill-defined. The aim of this study was to define specific ocular morbidity following orbital translocation. METHODS: The authors compared stable preoperative and postoperative orthoptic indices (i.e., angle of strabismus, ocular motility, and acuity) for 23 consecutive patients who underwent orbital translocation between 2000 and 2015 and noted the requirement for corrective surgery...

Although male-to-female transgender patients commonly seek facial feminization surgery, facial masculinization surgery in the female-to-male transgender population is unreported in the literature. This report documents the first known female-to-male facial masculinization surgery, including a new technique for creating an "Adam's apple" to enhance the facial masculine appearance of a natal female. The authors "reversed" the methods typically used to feminize male facial features, and modified the forehead, nose, and chin to masculinize the patient's natal female facial features...

BACKGROUND: In children with brachial plexus birth palsy (BPBP) undergoing tendon transfers to augment shoulder external rotation, it is unclear whether transfer of the latissimus dorsi with its combined latissimus dorsi and teres major (cLT) versus isolated teres major (iTM) tendon transfer yield different outcomes. METHODS: Records of patients with BPBP who underwent shoulder tendon transfers to augment external rotation were retrospectively reviewed. Transfer type (cLT or iTM) was considered indiscriminate by virtue of surgeon preference...

BACKGROUND: Limited evidence exists for meniscal repair outcomes in a multiligament reconstruction setting. Purpose/Hypothesis: The purpose of this study was to assess outcomes and failure rates of meniscal repair in patients who underwent multiligament reconstruction compared with patients who underwent multiligament reconstruction but lacked meniscal tears. The authors hypothesized that the outcomes of meniscal repair associated with concomitant multiligament reconstruction would significantly improve from preoperatively to postoperatively at a minimum of 2 years after the index surgery...

OBJECTIVE To assess use of a new radiographic method to determine the distance by which the tibial tuberosity should be advanced to reduce the patellar tendon-tibial plateau angle (PTA) to 90° by means of the modified Maquet technique (MMT) in dogs. SAMPLE 24 pelvic limbs from 12 adult medium-sized to large-breed canine cadavers. PROCEDURES Radiographs of stifle joints at 135° extension in true lateral position were used to determine tibial tuberosity advancement distances for use in the MMT. A method was devised to incorporate the planned osteotomy axis; distal patellar translations of 0, 3, 5, or 10 mm; and advancement cage implant application level along the osteotomy site in advancement planning measurements...

The aim of this study was to compare the fracture patterns after sagittal split osteotomy according to Obwegeser/Dal Pont (ODP) and Hunsuck/Epker (HE), as well as to investigate the relationship between lateral bone cut ending or angle and the incidence of unfavorable/bad splits. Postoperative cone-beam computed tomograms of 124 splits according to ODP and 60 according to HE were analyzed. ODP led to 75.8% and HE led to 60% lingual fractures with mandibular foramen contact. Horizontal fractures were found in 9...

BACKGROUND: A prominent mandibular angle (PMA) is a relatively common condition in Asians, and surgeons typically use the intraoral approach to treat it. However, the approach can have many drawbacks due to the limited operative field and view. The procedures of osteotomy are not easily manipulated, and an exact resection is difficult. In addition, some major complications can easily occur. This article presents a modified osteotomy method for the PMA that avoids these disadvantages and makes the procedure easier to execute...

STATEMENT OF PROBLEM: Radiotherapy results in diminished bone remodeling capacity and an elevated risk of osteoradionecrosis, which can negatively influence the survival rate of dental implants. Patients receiving radiotherapy are advised not to receive dental implants during or soon after completing their radiotherapy. PURPOSE: The purpose of this animal study was to investigate a 2-stage implant placement technique designed to diminish applied trauma on irradiated bone...

BACKGROUND: Crooked nose deformity is one of the most difficult issues to correct by rhinoplasty, as it can result in undesired late sequelae. Revision rates are often high, and numerous operational techniques have been tested. This study describes a crooked nose rhinoplasty technique that reduces the need for a double osteotomy in the long nasal bone. METHODS: This study included 26 patients with an I-shaped crooked nose deformity. In the surgical correction of the crooked nose deformity, previously defined techniques were applied to the cartilage identically...

A revision stem may be required after a femoral extended trochanteric osteotomy (ETO) is made during revision hip arthroplasty. The two main complications of straight cementless femoral stems are subsidence due to inadequate osteointegration and stress-shielding. We will describe an original revision method with ETO that uses a straight cementless stem. The goal of this method was to achieve the most extensive press-fit possible during stem implantation to improve the transmission of stresses to the bone and to prevent reduction in bone density...

Osteotomies are critical techniques in rhinoplasty. There are a variety of approaches, trajectories, and tools used with no widely standardized classification or nomenclature. Percutaneous osteotomies are gaining in popularity, and picture framing the nasomaxillary bone is crucial for predictable fracture and reproducible results. This is best accomplished with medial, lateral, and transverse osteotomies. Intermediate osteotomies are used less frequently, but provide more mobility. With a detailed understanding of anatomy and a thorough approach to nasal osteotomies, the contour and function of the bony vault can be reshaped with a successful outcome for both the surgeon and patient...

Temporomandibular joint (TMJ) ankylosis is a refractory disease that is difficult to predictably treat. This study evaluated the prognosis of using standard alloplastic TMJ prostheses for the treatment of TMJ ankylosis in Chinese patients with severe mandibular deficiency. Patients treated from 2013 to 2015 were reviewed. The computer-aided design and manufacture (CAD/CAM) technique was used to guide bony mass removal and locate the TMJ prosthesis (Biomet, USA). Eleven patients were included in this study. All prostheses were successfully installed and stabilized intraoperatively...

The nasal dorsum framework plays a major role in nasal and facial harmony. This study presents a new approach to an already known technique, intermediate osteotomies, which can be used routinely in patients with cosmetically unpleasant changes in eyebrow-tip line features, allowing the acquisition of a natural, aesthetically agreeable and harmonious dorsum contour, while preserving nasal function. The approach was evaluated retrospectively in 50 consecutive patients at a tertiary referral hospital. Patients were asked to complete a survey to rate their satisfaction with the cosmetic outcome on a 5-point visual analog scale (VAS) and to compare the impact of nasal obstruction on their quality of life, pre- and postoperatively, by completing the validated Nasal Obstruction Symptom Evaluation (NOSE) scale...

Three-dimensional (3-D) printing offers many potential advantages in designing and manufacturing plating systems for foot and ankle procedures that involve small, geometrically complex bony anatomy. Here, we describe the design and clinical use of a Ti-6Al-4V ELI bone plate (FastForward™ Bone Tether Plate, MedShape, Inc., Atlanta, GA) manufactured through 3-D printing processes. The plate protects the second metatarsal when tethering suture tape between the first and second metatarsals and is a part of a new procedure that corrects hallux valgus (bunion) deformities without relying on doing an osteotomy or fusion procedure...

BACKGROUD: Extensive wound dehiscence and wide plate and screw exposure in the early weeks following orthopaedic surgery in children is usually managed either by extensive debridement, lavage and secondary closure or hardware removal and external fixation. PATIENTS: Three children with LCP plate and screws exposure were managed by simple repetitive debridement and local wound care without any IV antibiotics, nor secondary closure or hardware removal. All three cases occurred in the tibia, one following tibial osteotomy in lateral hemimelia with a long history of previous surgeries, one following wide excision of a tibial Ewing sarcoma with chemo and radiotherapy, and the third following wide excision of a 12cm necrotic tibial segment due to chronic osteomyelitis...

BACKGROUND: Moderate to severe midfoot-forefoot varus deformities are commonly found in several conditions. However, few techniques are available to correct these deformities. So, we evaluated the clinical and radiological outcomes of patients who underwent midfoot derotational osteotomy to achieve plantigrade foot. METHODS: From 2006 to 2014, 6 patients (7 feet) underwent midfoot derotational osteotomy. A visual analog scale (VAS) pain and the American Orthopedic Foot & Ankle Society (AOFAS) functional score were evaluated...

Mice are extensively used for experimental bone-healing studies. However, there are few established nondestructive in vivo techniques for longitudinal fracture-healing analysis in mice, including in vivo micro-computed tomography (μCT) and radiography. Importantly, none of the established methods can discriminate between non-mineralized fibrous tissue and cartilage in the soft fracture callus. Therefore, the objective was to establish high-resolution in vivo magnetic resonance imaging (MRI) for the longitudinal assessment of soft callus formation during bone healing in mice...
