Unstable trochanteric femur fractures are common fractures that are difficult to manage. We conducted a prospective study to compare functional outcomes and complications of 2 different implant designs, proximal femur nail (PFN) and proximal femur locking compression plate (PFLCP), used in internal fixation of unstable trochanteric femur fractures. On hospital admission, 48 patients with unstable trochanteric fractures were randomly assigned (using a sealed envelope method) to treatment with either PFN (24 patients) or PFLCP (24 patients)...

The incidence of lateral patella dislocations is high, particularly in young females. Beside traumatic cases, many patients present with specific anatomical factors that predispose to lateral patella dislocations (torsional abnormalities of the femur or the tibia, trochlea dysplasia, patella alta, etc). It is of utmost importance to correct those pathologic factors during concomitant procedures as isolated reconstructions of the medial patellofemoral ligament would fail in the presence of severe anatomic risk factors...

Fred L Speck, Randal P Morris, Ronald W Lindsey
Complex tibia fractures are often provisionally stabilized with external fixation prior to definitive fracture fixation. Bicortical defects, such as those left after removal of a fixator pin, can decrease the torsional strength of long bone. Evaluating the effect of subsequent plate fixation in close proximity to a defect on the torsional strength of the tibia is the purpose of this study. Eight groups of 5 fourth-generation left composite tibias were tested to failure in torsion. The experimental plated groups consisted of bicortical defects at 3 cm, 2 cm, and 1 cm distal to the plate end, with 1 plated group without a defect...

Subscapularis tenotomy (ST) has been the standard method of mobilizing the subscapularis during the approach to a total shoulder arthroplasty (TSA). Recently, lesser tuberosity osteotomy (LTO), which avoids subscapularis complications, has gained in popularity. We performed a systematic review to elucidate any differences in clinical or radiographic outcomes between ST and LTO. Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we identified clinical and/or radiographic TSA studies with minimum mean 2-year follow-up and level I to IV evidence...

We conducted a study to evaluate the operative details, perioperative complications, and short-term outcomes associated with combined anterior-posterior decompression and fusion (CAPDF) for treating cervical spondylotic myelopathy (CSM). We retrospectively reviewed the charts of 21 patients who underwent CAPDF at our institution. Pertinent information, including demographics, surgery indication, perioperative complications, operative time, levels fused (and number of levels fused) anteriorly and posteriorly, estimated blood loss, and length of stay, was gathered...

Usama Qayyum, Diego Villacis, Charles M Jobin
Pronator teres muscle strain is a rare sporting injury reported thus far only in cricket and golf players. The injury appears to occur when the sporting club or racket strikes the ground during a forceful swing and causes the elbow to experience an eccentric force during resisted elbow flexion and pronation. On initial presentation, this injury can be mistaken for injury to the medial ulnar collateral ligament, or exacerbation of medial epicondylitis. On examination, bruising and tenderness distal to the elbow over the course of the pronator teres are often present...

Nail breakage is a known complication of intramedullary nail (IMN) fixation of tibial fractures. Several case reports have described unique methods used to facilitate removal of broken IMNs. In this article, we describe an efficient technique for extracting broken tibial IMNs-a technique that can be used before attempting more invasive extraction methods.

The following report provides clinical follow-up on a National Football League player who sustained a complete cervical spinal cord injury (SCI) while tackling an opposing player in 2007. He received prompt medical and surgical care based on then-current recommendations, but was also treated with systemic hypothermia soon after his injury, which was controversial at the time. Since then, smaller randomized human studies have described the tolerable safety profile, efficacy, and potential benefits of this intervention in acute SCI in humans...

Superior mesenteric artery (SMA) syndrome is a rare and potentially life-threatening complication of scoliosis surgery. The anatomical relationship of the duodenum and the superior mesenteric artery, the correction of angular deformity of the spine, and the normal adolescent growth spurt all contribute to the condition. We report the case of a 14-year-old boy who had a history of idiopathic scoliosis and presented with bilious vomiting that had persisted for 7 days after posterior T9-L4 fusion with instrumentation...

Complex glenoid deformities present the most difficult challenges in shoulder arthroplasty. These deformities may be caused by severe degenerative or congenital deformity, posttraumatic anatomy, tumor, or, in most cases, bone loss after glenoid failure in anatomical total shoulder arthroplasty. Methods of treating severe bone loss have included inlay and onlay bone-graft options with augmented fixation and, in severe cases, salvage hemiarthroplasty with limited goal expectations. Unfortunately, none of these methods has provided consistently satisfactory reproducible results...

There is no shortcut to accurate diagnosis in the patellofemoral pain patient. Most important in the process is a desire and ability to specifically identify the structural and biomechanical origin of pain. This can be elusive and often requires a careful analysis of all factors affecting the patient, including documenting his or her specific history of pain origin and specific treatments to date, and acknowledging the patient's localization of the pain origin. Many patients can pinpoint the site of pain origin when given the time and encouragement to do so...

William R Post, Scott F Dye
We present a rational, scientific, low-risk approach to patellofemoral pain (anterior knee pain) based on an understanding of tissue homeostasis. Loss of tissue homeostasis from overload and/or injury produces pain. Bone overload and synovial inflammation are common sources of such pain. Chondromalacia and malalignment are findings that almost always do not need to be "corrected" to relieve pain. Patience and persistence in nonoperative care results in consistent success. Surgery should be rare and done only after extensive nonoperative management and in the setting of clearly defined pathology...

Repair, reefing, and advancement of the medial patellofemoral ligament (MPFL) and medial retinacular structures can be performed as an isolated procedure or in conjunction with distal realignment procedures for patients with patellar instability. Although various operative techniques have been described, understanding the appropriate clinical indications and MPFL injury patterns ultimately determines the success or failure of the procedure. MPFL repair is best indicated in the acute setting, particularly if there is a patella- or femoral-based avulsion...

Rehabilitation is the hallmark of the nonoperative treatment of anterior knee pain (AKP). Whether a patient has had appropriate rehabilitation can be assessed in the office with a selection of basic and advanced screening tests. Most important, providing specific instructions in your referral to a therapist skilled in treating patients with AKP can ensure that any identified deficits are appropriately addressed. The etiology of AKP is multifactorial. Whatever its "cause," AKP alters neuromuscular function, and correcting these altered body movement patterns will benefit the patient...

Medial patellofemoral ligament (MPFL) reconstruction is often required after failed nonoperative management of lateral patellar instability. It is important to properly re-create the native ligament to avoid altering patellofemoral biomechanics. Such alterations can cause knee stiffness, anterior knee pain, and patellofemoral chondrosis. Incorrect femoral location is the most common mistake that affects MPFL graft biomechanics. Authors have described multiple radiographic and anatomical landmarks that assist in determining the appropriate location, and time should be taken to accurately localize this position...

Our purpose is to provide simple guidelines for the diagnosis and early care of patellofemoral disorders. Any clinician who treats knee problems, including family practitioners, rheumatologists, orthopedic surgeons, or physical therapists, must know how to make the correct diagnosis, or at least a presumptive diagnosis, at the initial visit. This can avoid unneeded and costly tests, ineffective treatment, and even damaging exercises and unnecessary surgery. The diagnosis of patellofemoral disorders is confusing because they can have many causes...

We conducted a study to assess 30 expert hip arthroscopists' ability to identify common surface landmarks used during hip arthroscopy. Thirty hip arthroscopists independently performed a blinded examination of an awake supine human volunteer for identification of 5 surface landmarks: anterior superior iliac spine (ASIS), tip of greater trochanter (GT), rectus origin (RO), superficial inguinal ring (SIR), and psoas tendon (PT). The examiners applied the labels ASIS, GT, RO, SIR, and PT to the landmarks. An ultrasonographer performed a musculoskeletal ultrasound examination and applied labels as well, and a photographer documented the examiner labels after obtaining overhead and lateral digital images with use of fixed camera mounts...

Goals of total hip arthroplasty (THA) include pain alleviation, motion restoration, and normalization of leg-length inequality. Asymmetric leg lengths are associated with nerve traction injuries, lower extremity joint pain, sacroiliac discomfort, low back pain, and patient dissatisfaction. The authors present an innovative use of a modified ball-tip guide rod to help accurately restore leg length and femoral offset during direct anterior THA.
