INTRODUCTION: The purpose of this systematic review and meta-analysis was to evaluate the efficacy of concurrent cartilage procedures during high tibial osteotomy (HTO) for medial compartment osteoarthritis (OA) by comparing the outcomes of studies that directly compared the use of HTO plus concurrent cartilage procedures versus HTO alone. MATERIALS AND METHODS: Results that are possible to be compared in more than two articles were presented as forest plots. A 95% confidence interval was calculated for each effect size, and we calculated the I (2) statistic, which presents the percentage of total variation attributable to the heterogeneity among studies...

The aim of this study is to introduce a surgical technique that can maintain blood supply to prevent condylar resorption in the extracorporeal reduction of condylar fracture. Neither the medial pterygoid muscle on the ramal bone nor the lateral pterygoid muscle on the condylar fragment was detached after vertical ramal osteotomy. Thus, reduction was performed in the intracorporeal state. Therefore, blood supply was expected to be maintained to the fragments of both the condylar and ramal bones. On postoperative radiographs, the anatomical outline of the fractured condyle was well restored, and the occlusion was stable...

BACKGROUND: Idiopathic genu valgum is a frequently diagnosed growth disorder in adolescence. Whenever the possibilities of conservative therapy have been exhausted, leg straightening by means of hemiepiphysiodesis has become the standard form of treatment. Because of their flexible screw-plate connection, eight-Plates have been reported in the literature to lead to lower complications regarding implant loosening and fracture compared to other implants. The aim of this retrospective survey was to analyse our own patient population who were treated for genu valgum by means of temporary hemiepiphysiodesis near the knee using eight-Plates to modulate growth...

RATIONALE: Extremely sharp angular spinal deformity of healed tuberculosis can be corrected by vertebral column resection (VCR). However, the VCR techniques have many limitations including spinal column instability, greater blood loss, and greater risk of neurologic deficit. PATIENT CONCERNS: We described a new spinal osteotomy technique to collect sharp angular spinal deformity in Pott disease. A 52-year-old woman presented with back pain and gait imbalance. DIAGNOSIS: The kyphosis of healed tuberculosis was diagnosed based on history and imaging examinations...

BACKGROUND: Both internal and external distraction devices have been used successfully in correcting midface hypoplasia. Although the indication for surgery and the osteotomy techniques may be similar, deciding when to use internal versus external devices has not been studied. The authors studied patient-reported outcomes with FACE-Q and functional surveys for internal and external devices for midface distraction patients. METHODS: Patients who underwent distraction advancement after Le Fort I and Le Fort III were surveyed using the FACE-Q survey and a functional survey...

Orthopedic complications of intravenous (IV) infiltration are rare, with only a handful of cases reported in the literature. Because of the relatively high rate of IV infiltration in neonates, however, such complications do occur and can include growth arrest, limb length discrepancy, and joint deformities that require surgical intervention. The risk of these complications is highest in preterm neonates. A 7-year-old girl presented to our institution with a severe valgus hindfoot deformity that developed secondary to a neonatal IV infiltration injury...

OBJECTIVES: To test the hypothesis that there would be no difference in heat production by reducing the number of drills during the implant site preparation relative to conventional drilling sequence. METHODS: A total of 120 implant site preparations with 3 different diameters (3.6, 4.3, and 4.6 mm) were performed on bovine ribs. Within the same diameter group, half of the preparations were performed by a simplified drilling procedure (pilot drill + final diameter drill) and other half using the conventional drilling protocol (pilot drill followed by graduated series of drills to widen the site)...

Meralgia paresthetica is a non-life-threatening neurological disorder characterized by numbness, tingling, and burning pain over the anterolateral thigh due to impingement of the lateral femoral cutaneous nerve. This disorder has been seen in patients with diabetes mellitus and obesity, but has also been observed in patients after procedures such as posterior spine surgery, iliac crest bone grafts, lumbar disk surgery, hernia repair, appendectomies, and pelvic osteotomies that ultimately lead to compression or damage to the lateral femoral cutaneous nerve...

The implant site preparation through drilling procedures may cause bone thermonecrosis. The aim of this in vitro study was to evaluate, using a thermal probe, the overheating at implant sites during osteotomies through two different drilling methods (continuous drilling technique versus intermittent drilling technique) using irrigation at different temperatures. Five implant sites of 13mm in length were performed on sixteen blocks (fresh bovine ribs), for a total amount of 80 implant sites. The thermal probe PT-100 was positioned at 5 mm from each site...

Patellofemoral instability is an extremely limiting pathology in young and active patients. Anatomical reasons for patellar instability, such as high-riding patella, elevated distance from the tibial tuberosity to trochlear groove (TTTG), trochlear dysplasia, insufficient medial patellofemoral ligament (MPFL) and malpositioning of the axes and torsion can lead to chronic patellofemoral instability and must be thoroughly analyzed. The first dislocation can be treated conservatively, with the exception of an osteochondral defect...

INTRODUCTION: The main challenge during the osteosynthesis of a bilateral sagittal split osteotomy (BSSO) is to take into account the correct position of the condyle. Adjustable plates can be used to fine-tune the final occlusion without changing the osteosynthesis. A new type of adjustable plate is presented in this article. The aim is to assess the mechanical reliability of this system during the surgery and during the healing period, thanks to a preliminary prospective on 15 consecutive cases...

PURPOSE: Union of a scaphoid fracture after fixation is influenced by various factors, one of which is fracture stability. This study aims to compare the biomechanical stability of 3 different types of scaphoid fracture fixation in a scaphoid nonunion model. METHODS: Thirty cadaveric scaphoid specimens were assigned to one of 3 different fixation groups: (1) single 3.0-mm compression screw, (2) two 2.2-mm screws, and (3) scaphoid plate. A 3-mm volar wedge osteotomy was created at the scaphoid waist to simulate a nonunion model...
