Aims Free vascularised fibular grafting has been used for the treatment of large bony defects more than 40 years. However, there is little information about risk factors failure and whether newer locking techniques fixation improve rates union. The purpose this study was to compare union free grafts fixed with traditional techniques, quantify nonunion failure. Patients Methods A retrospective review involved 134 consecutive procedures over a period 20 Of these, 25 were excluded leaving 109...
Commentary Dr. Joshi and the SOFIE research group performed a multicenter, prospective, pragmatic, randomized controlled trial (RCT) in which they found no significant difference Disabilities of Arm, Shoulder Hand (DASH) score at 12 months (their primary outcome) between surgical nonsurgical treatment closed, displaced olecranon fractures patients over age 75 years. They thus concluded that nonoperative is reasonable option elderly patients. This study aimed to answer relevant timely...
Background Carpal instability is defined as a condition where wrist motion and/or loading creates mechanical dysfunction, resulting in weakness, pain and decreased function. When conventional methods do not identify the patterns, yet clinical signs of exist, diagnosis dynamic often suggested to describe carpal derangement manifested only during wrist's active or stress. We addressed question: can advanced MRI techniques provide quantitative means evaluate supplement standard static...
While there are advantages and disadvantages to both processed nerve allografts (PNA) conduits, a large, well-controlled prospective study is needed compare the efficacy delineate how each of these repair tools can be best applied digital injuries. We hypothesized that PNA repairs would achieve superior functional recovery for longer length gaps compared with conduit-based repairs.Patients (aged 18-69 years) presenting suspected acute or subacute (less than 24 weeks old) injuries were...
There are many reasons why orthopaedic surgeons move or change careers. We asked the questions: (1) What is geographic distribution of with respect to age, sex, and race ethnicity? (2) How has our workforce changed over time regard these factors? (3) Are there any patterns trends detected regarding policy regulatory events that coincide differences?
Magnetic resonance imaging (MRI) using 1.5T or 3.0T systems is routinely employed for assessing wrist pathology; however, due to off-resonance artifacts and high power deposition, these high-field have drawbacks real-time (RT) of the moving wrist. Recently, high-performance 0.55T MRI become available. In this proof-of-concept study, we tested hypothesis that RT-MRI during continuous, active, uninterrupted motion feasible with a system at temporal resolutions below 100 ms resulting images...
<b>Introduction</b> Most surgical techniques for scapholunate interosseous ligament (SLIL) repair address only the dorsal component of ligament, potentially leading to high failure rates. We introduce a new technique reconstruct volar SLIL using portion long radiolunate (LRL). A biomechanical evaluation was performed evaluate rupture strength this repair, and subsequent anatomic study verify that would not compromise blood supply either scaphoid or lunate. <b>Methods</b> reconstruction...
Purpose In an attempt to restore natural carpal kinematics more closely, bone-ligament-bone (BLB) grafts have been described for treating scapholunate (SL) injury. this article we report the long-term results of capitohamate BLB autograft treatment SL dissociation. Methods The medical records patients treated with dissociation were retrospectively reviewed. Twenty-three available evaluation. Patients sent a Disabilities Arm, Shoulder, and Hand (DASH) Patient-Rated Wrist Evaluation (PRWE)...
Vascularized free fibula transfer is an attractive option for the treatment of segmental bone defects because faster union rates, fewer fatigue fractures, rapid hypertrophy, and less resorption compared with nonvascularized transfer. It classically indicated those patients >6 to 8 cm. The presence several peroneal artery fasciocutaneous perforators also makes inclusion a skin paddle possible. Although rare, surgeon must be aware possible complications associated this procedure. A careful...
Extensor tendon entrapment in the presence of distal radius fracture is a known but relatively uncommon complication. Single or entire compartment has been described through literature youths and adults. However these findings generally are limited to certain age demographic found on advanced imaging unable be confirmed intraoperatively. We describe our knowledge first description second extensor an adult seen computerized tomography scan
Primary thumb carpometacarpal (CMC) osteoarthritis is one of the most common conditions encountered by hand surgeons. Of vast number operations that have been proposed, none demonstrated results significantly superior to trapeziectomy alone.
Shoulder arthroplasty is becoming increasingly common. With evolving implant designs, multiple humeral stem options exist for the surgeon to choose from. New stemless and short-stem systems are modular, remove less native bone stock, better adapt patient anatomy. It has been suggested that shorter implants may be protective against periprosthetic fracture; however, this not mechanistically evaluated. Therefore, study aimed biomechanically test synthetic humeri with long-stem, short-stem,...
Primary sarcomas originating from the bones of hand and wrist are rare but carry a significant burden morbidity.National Cancer Institute's Surveillance, Epidemiology End Result database 1975 to 2017 was queried report incidence survival data in 237 patients United States. Kaplan-Meier Cox regression were used determine prognostic factors affecting survival. χ2 test assess correlation.Incidence sarcoma 0.017 per 100 000 persons has not significantly changed since (p > 0.05).
