To date, all the authors who have recommended external rotation osteotomy (ERO) in the late treatment of obstetrical brachial plexus palsy (OBPP), have neglected upper limb length discrepancy, which is an another sequelae of OBPP. In this paper, a new technique is reported for the late treatment of OBPP patients with upper limb length discrepancy, in which both humeral external rotation osteotomy (ERO) and lengthening are applied with an intramedullary elongation nail. With this technique, upper limb function is improved through re-orientation of the shoulder arc to a more functional range, and further improvements will be seen in the appearance of the upper limb with the elimination of length discrepancy...

Secondary limb lengthening after intercalary bone resection in pediatric patients is still challenging. After the resection, a free fibula autograft can be used to reconstruct the osseous gap. However, in particular in young pediatric patients, insufficient growth of the epiphyseal plate after transplantation may lead to a significant limb-length discrepancy (LLD). In this case, the autograft was used for limb lengthening. We report on the lengthening of a humerus regenerate after fibula autograft transplantation into a humeral defect in a pediatric/young adolescent patient...

Compression techniques seem to be the primary factor in determining the success of both plating and nailing techniques for the management of acute fractures and for delayed and nonunion management of these fractures. An intramedullary nail that can provide continual compression (like a plate) and mechanical manipulation of the callous throughout the course of treatment is an ideal device that provides all the advantages of plating and nailing and avoids the noted limitations of both. The UNYTE compression humeral nail is based on the PRECICE intramedullary limb lengthening system...

Limb equalization using the Ilizarov method has evolved and adapted the use of internal lengthening devices. One of the newest devices, termed "PRECICE," is a magnetically controlled telescoping nail. Complications such as pin site infection and skin irritation are eliminated. Despite trauma surgeons' familiarity with intramedullary nailing, the Ilizarov method requires sound knowledge of deformity analysis and awareness of specific complications associated with distraction osteogenesis. This manuscript discusses some of the practical preoperative and intraoperative components of limb lengthening...

The operative elongation of limbs has long been a goal of orthopaedic surgeons. Indeed, the very first external skeletal fixators, although designed for stabilization of displaced fractures, were also used to overcome the posttrauma shortening that so commonly accompanies fracture deformities.

BACKGROUND: Leg lengthening occurs in 83% of primary total knee arthroplasty (TKA). The effects of leg length discrepancy (LLD) on THA patients are well established. However, patient function and satisfaction associated with LLD after primary TKA has not been analyzed. This study aimed to quantify the magnitude of limb lengthening, identify radiographic and perceived LLD, and correlate these with predictive factors and functional outcomes in a series of TKA patients. METHODS: Patients undergoing primary TKA who met inclusion criteria were prospectively enrolled in this study...

BACKGROUND: Antegrade intramedullary (IM) nailing for skeletally immature femur fractures can damage the capital femoral epiphysis blood supply, leading to avascular necrosis (AVN) of the femoral head. Reported AVN rates are 2% for piriformis entry and 1.4% for trochanteric entry. None of previous reports described IM lengthening nails for limb lengthening procedures. We have used self-lengthening telescopic nails with a proximal Herzog bend and standard trochanteric entry for femoral lengthening in children...

The overwhelming use of rat models in nerve regeneration studies is likely to induce skewness in treatment outcomes. To address the problem, this study was conducted in 8 adult guinea pigs of either sex to investigate the suitability of guinea pig as an alternative model for nerve regeneration studies. A crush injury was inflicted to the sciatic nerve of the left limb, which led to significant decrease in the pain perception and neurorecovery up to the 4(th) weak. Lengthening of foot print and shortening of toe spread were observed in the paw after nerve injury...

Background and purpose - Hexapod ring fixators such as the Taylor Spatial Frame (TSF) have shown good outcomes. However, there have only been a few studies comparing the use of TSF with various etiologies of the deformity. We compared the use of TSF in congenital and acquired deformities in children. Patients and methods - We reviewed 213 lower extremity reconstructive procedures with the TSF in 192 patients who were operated between October 2000 and October 2015. 128 procedures (67 proximal tibiae, 51 distal femora, and 10 distal tibiae) in 117 children (median age 14 (4-18) years; 59 girls) fulfilled the inclusion criteria...

Limb lengthening is now an accepted practice in orthopaedic surgery. The principles of distraction osteogenesis have become well established with the use of external fixators, utilizing both monolateral and ring fixators. Corticotomy technique, frame stability, lengthening rate and rhythm all contribute to the formation of bone regenerate and tissues. Complications are however common including pin-site infection, soft tissue tethering from the pins and wires resulting in pain, regenerate deformity from soft tissue forces or fracture following frame removal and patient intolerance of the frames during treatment...

BACKGROUND: The long-limb Roux-en-Y gastric bypass (LLRYGB) was introduced in 1987 as a salvage operation for inadequate weight loss after a standard Roux-en-Y gastric bypass (RYGB). METHODS: We report on 53 consecutive patients (44 females) with conversion of a failed RYGB to a LLRYGB performed by a single surgeon between 2002 and 2014. No patient had an ascertainable anatomic abnormality to explain his/her weight regain. LLRYGB revision consisted of a 75-cm to 100-cm alimentary Roux limb and a 75-cm to 100-cm common channel; after 2011, in suitable patients, the Roux limb was lengthened to greater than 250 cm...

 Selective dorsal rhizotomy (SDR) has been used to treat children with spastic cerebral palsy (CP) for over three decades. However, little is known about the outcomes of childhood SDR in adults.  Objectives: 1) To study the effects of childhood SDR on the quality of life and ambulatory function in adult life. 2) To determine late side effects of SDR in adults.   Methods: Adults (> 17.9 years) who underwent SDR in childhood (2 - 17.9 years) between 1987 and 2013 were surveyed in 2015. Patients completed a survey, including questions on demographic information, quality of life, health, surgical outcomes, motor function, manual ability, pain, braces/orthotics, post-SDR treatment, living situation, education level, work status, and side effects of SDR...

BACKGROUND: Limb length discrepancy (LLD) after total hip arthroplasty (THA) is a common problem which cannot be completely resolved. Many techniques have been described in order to minimize postoperative LLD, but most of these techniques are difficult to apply. Ideal technique must be simple and accurate. The most simple technique using a suture tied on the skin has well-known limitations, but its accuracy has not been evaluated before. MATERIALS AND METHODS: Sixty THAs in sixty patients (mean age 71 years, 1:1 male to female ratio) with hip osteoarthritis (37 cases in the right, and 23 cases in the left side) were studied in this prospective study...

OBJECTIVE: This study aimed to examine the corticomotor excitability changes after peripheral nerve electrical stimulation (PNS) on the stroke-impaired arm. DESIGN: This randomized cross-over study included 32 subjects with chronic stroke. They received a 1-hr PNS or placebo PNS by random order to the ulnar and radial nerves of the paretic arm in separate sessions. The primary outcome was excitability of the corticospinal projections for the contralateral first dorsal interosseous hand muscle in terms of slope of the recruitment curve, peak motor-evoked potential amplitude, and duration of the cortical silent period, measured with transcranial magnetic stimulation on both cerebral hemispheres...

Simultaneous deformity correction in the frontal and sagittal plane becomes more and more an important part of intramedullary lengthening to avoid further operative procedures. Such as in fracture treatment blocking screws can be used for alignment control if osteotomy is performed in the metaphyseal bone. 31 intramedullary lengthening procedures between 2009 and 2011 were retrospectively analysed for precision of simultaneous deformity correction. The average planned correction to the HKA was 2.4° (0.1°-8...
