Without clinical guideline on the optimal timing for primary total hip replacement (THR), patients often receive the operation with delay. Delaying THR may negatively affect long-term health-related quality of life, but its economic effects are unclear. We evaluated the costs and health benefits of timely primary THR for functionally independent adult patients with end-stage osteoarthritis (OA) compared to non-surgical therapy followed by THR after progression to functional dependence (delayed THR), and non-surgical therapy alone (Medical Therapy), from a German Social Health Insurance (SHI) perspective...

Posttraumatic deformities after vertebral fractures are challenging for orthopedic surgeons in the non-operative and operative field. Especially osteoporotic fractures may cause a hyperkyphosis resulting in segmental or global sagittal imbalance and chronic back pain. Different vertebral osteotomies are potent to restore sagittal profile but show a very high perioperative risk including neurological and soft tissue complications. In addition, some of these extensive operations require a two-step procedure including posterior and anterior approaches...

In association with the growing interests in pain management, several modalities to control postoperative pain have been proposed and examined for the efficacy in the recent studies. Various modes of peripheral nerve block have been proposed and the effectiveness and safety have been examined for each of those techniques. We have described our clinical experiences, showing that continuous femoral nerve block could provide a satisfactory analgesic effect after total hip arthroplasty (THA) procedure. In this study, we compared the effectiveness and safety of continuous femoral nerve block with and without sciatic nerve blockade on pain control after THA...

Spinal epidural abscess (SEA) is a serious condition that can be challenging to diagnose due to nonspecific symptomology and delayed presentation. Despite this, it requires prompt recognition and management in order to prevent permanent neurologic sequelae. Several recent studies have improved our understanding of SEA. Herein, we summarize the recent literature from the past 10 years relevant to SEA diagnosis, management and outcome. While surgical care remains the mainstay of treatment, a select subset of SEA patients may be managed without operative intervention...

First administered in November 1963, the orthopedic in-training examination (OITE) is now distributed to more than 4000 residents in over 20 countries and has become important for evaluation of resident fund of knowledge. Several studies have assessed the effect of didactic programs on resident performance, but only recently has it become possible to assess detailed testtaking metrics such as time spent per question. Here, we report the first assessment of resident OITE performance utilizing this full electronic dataset from two large academic institutions...

REVIEW
Scott D Augustine
Several studies have shown that the waste heat from forced-air warming (FAW) escapes near the floor and warms the contaminated air resident near the floor. The waste heat then forms into convection currents that rise up and contaminate the sterile field above the surgical table. It has been shown that a single airborne bacterium can cause a periprosthetic joint infection (PJI) following joint replacement surgery. We retrospectively compared PJI rates during a period of FAW to a period of air-free conductive fabric electric warming (CFW) at three hospitals...

Total hip arthroplasty (THA) is one of the successful and cost-benefit surgical treatments. One-stage bilateral THA (BTHA) has a large number of advantages, although there are concerns about the higher complications in this procedure. Aim of our study was to evaluate the complications and outcomes of cementless one-stage BTHA in osteoarthritis patients. A total of 147 patients from 2009 till 2012, underwent one-stage BTHA in Milad and Erfan hospitals, Tehran, Iran. A prospective analysis of the functional outcomes and complications of one-stage BTHA through Hardinge approach in patients with osteoarthritis was performed...

There have been no studies investigating three-dimensional (3D) alteration of the coracohumeral distance (CHD) associated with shoulder motion. The aim of this study was to investigate the change of 3D-CHD with the arm in flexion/internal rotation and horizontal adduction. Six intact shoulders of four healthy volunteers were obtained for this study. MRI was taken in four arm positions: with the arm in internal rotation at 0°, 45°, and 90° of flexion, and 90° of flexion with maximum horizontal adduction...

The aim of our review is to identify the reconstruction technique that has a superior functional outcome and decreased number of complications for the anterior cruciate ligament (ACL). We have divided our review into 2 sections. Our primary question evaluates the functional results and complications of autografts compared to allografts for ACL reconstruction. Our subsidiary question evaluates the functional results and complications of bone-patellar tendon-bone (BPTB) autografts compared to hamstring tendon autografts...

Normal variations in anatomy in the skeletally immature patient may be mistaken for fracture or injury due to the presence of secondary centers of ossification. Variations in imaging exist from patient to patient based on sex, age, and may even vary from one extremity to the other on the same patient. Despite differences in the appearance of the bony anatomy of the elbow there are certain landmarks and relationships, which can help, distinguish normal from abnormal. We review common radiographic parameters and pitfalls associated in the evaluation of pediatric elbow imaging...

Hamstring tendon autografts are used for reconstruction of the anterior cruciate ligament. This study tested the hypothesis that a 5-strand hamstring autograft construct is superior in strength to a 4-strand construct. Four-strand and 5-strand tendon grafts constructs were prepared from ovine flexor tendons and then tested in a uniaxial electromechanical load system with suspensory fixation. The 4-strand and 5-strand constructs were pre-conditioned, stress-relaxed and loaded to ultimate failure. Stress-relaxation, stiffness and ultimate load were compared using a one-way ANOVA...

The IlluminOss(®) system (IS) uses a light-curable polymer contained within an inflatable balloon catheter, forming a patient customized intramedullary implant. A registry was established in Germany and The Netherlands to prospectively collect technical and clinical outcomes in patients treated with IS for fractures of the phalange, metacarpal, radius, ulna, distal radius, fibula, clavicle and/or olecranon. Humeral, femoral, tibial and pelvic fractures were included under compassionate use. Procedural success included successful placement of the device at the target fracture site and achievement of fracture stabilization...

REVIEW
James Holton, Tahir Yousri, George Arealis, Ofer Levy
Fracture sequelae of the proximal humerus poses a complex management decision due to the frequent deformity and its consequences on the peri-articular soft tissues. These patients are frequently elderly with significant medical comorbidities. Due to the age of the patient there is frequently rotator cuff deficiency and therefore the reverse shoulder arthroplasty (RSA) becomes the arthroplasty of choice. We have performed a systematic review of the literature and report nine studies presenting RSA for the treatment of fracture sequelae of the proximal humerus...

Orthopedic trauma surgery is a critical component of resident education. Surgical case logs obtained from the Accreditation Council of Graduate Medical Students from 2009 to 2013 for orthopedic surgery residents were examined for variability between the 90(th) and 10(th) percentiles in regards to the volume of cases performed. There was an upward trend in the mean number of cases performed by senior residents from 484.4 in 2009 to 534.5 in 2013, representing a 10.3% increase. There was a statistically significant increase in the number of cases performed for humerus/elbow, forearm/wrist, and pelvis/hip during this period (P<0...

Schwannomas are benign neurogenic tumors of peripheral nerves that originate from neural sheath. The aim of this case report is to bring to mind the schwannoma in the patient with knee pain. A 39-year-old woman presented with a complaint of knee pain of three months history. After surgical intervention, the patient's complaints completely disappeared in the post-operative period. This should come to mind in the differential diagnosis of knee pain.

With disease progression, avascular necrosis (AVN) of the femoral head may lead to a collapse of the articular surface. The exact pathophysiology of AVN remains unclear, although several conditions are known that can result in spontaneous cell death, leading to a reduction of trabecular bone and the development of AVN. Hip AVN treatment is stage-dependent in which two main stages of the disease can be distinguished: pre-collapse (ARCO 0-II) and post-collapse stage (ARCO III-IV, crescent sign). In the pre-collapse phase, core decompression (CD), with or without the addition of bone marrow (e...

A case of an adolescent female patient who suffered from first grade open multi-fragment fracture of the tibia (AO42-C2) with a large hypermobile intermediate fragment is presented in this case report. Intramedullary nailing of the tibia remains the treatment of choice despite a high risk of malformation and anterior knee pain especially in multi-fragment fractures. Here the suprapatellar approach as a semiextended nailing technique seems favorable. The specialty in our case was an early change of procedures necessary due to persistent swelling during external fixation based on the hypermobile intermediate fragment...
