BACKGROUND: Decompression surgery for lumbar spinal stenosis (LSS) is the most common spinal procedure in the elderly. To avoid persisting low back pain, adding arthrodesis has been recommended, especially if there is a coexisting degenerative spondylolisthesis. However, this strategy remains controversial, resulting in practice-based variation. PURPOSE: To evaluate in a pragmatic study if surgical selection criteria and variation in use of arthrodesis in three Scandinavian countries can be linked to variation in treatment effectiveness...

I report my personal experience over three decades in the treatment of carpal collapse due to scapholunate collapse and scaphoid nonunion. I have used the proximal carpal row resection performed through palmar approach, the scaphoidectomy and double-column midcarpal arthrodesis, and scaphoidectomy with midcarpal tenodesis. Diagnostic arthroscopy is essential for staging and surgical decision making regarding the type of treatment. The details of the surgical techniques, tips, results and possible complications are described for each method...

OBJECTIVE: To evaluate whether postoperative continuous wound infiltration of levobupivacaine through two submuscular catheters connected to two elastomeric pumps after lumbar instrumented arthrodesis is more effective than intravenous patient-controlled analgesia. MATERIAL AND METHODS: An observational, prospective cohorts study was carried out. The visual analogue scale, the need for additional rescue analgesia and the onset of adverse effects were recorded. RESULTS: Pain records measured with visual analogue scale scale were significantly lower in the 48hours postoperative record at rest (p=...

Proximal interphalangeal (PIP) joint arthritis causes debilitating hand pain and instability leading to significant functional impairment. Arthrodesis remains the gold standard for treatment of PIP arthritis. We present a minimally invasive PIP arthrodesis that provides rigid fixation with a headless compression screw. Seven patients who presented to the senior author with PIP joint arthritis underwent PIP arthrodesis by minimally invasive technique. A 1 cm transverse incision is made over the PIP joint, incising skin, central band, and articular capsule...

Autologous bone graft remains the only clinically available source of graft material with osteogenic, osteoinductive, and osteoconductive properties. Although iliac crest autologous bone graft has long served as the benchmark, reamed autogenous bone graft offers several advantages. Reamed autograft has a biochemical and cellular profile that is at least equivalent, and perhaps superior, to that of iliac crest autograft. In addition, larger volumes of reamed autograft can be obtained via less-invasive techniques, giving surgeons an accessible source of mesenchymal stem cells that can be reliably and repeatedly harvested...

Instrumentation failure is a common complication following complex spinal reconstruction and deformity correction. Rod fracture is the most frequent mode of hardware failure and often occurs at or near a 3-column osteotomy site. Titanium (Ti) rods are commonly utilized for spinal fixations, however, theoretically stiffer materials, such as cobalt-chrome (CoCr) rods are also available. Despite ongoing use in clinical practice, there is little biomechanical evidence that compares the construct ability to withstand fatigue stress for Ti and Co-Cr rods...

Nerve dysfunction after upper extremity orthopedic surgery is a recognized complication, and may result from a variety of different causes. Hand and wrist surgery require incisions and retraction that necessarily border on small peripheral nerves, which may be difficult to identify and protect with absolute certainty. This article reviews the rates and ranges of reported nerve dysfunction with respect to common surgical interventions for the distal upper extremity, including wrist arthroplasty, wrist arthrodesis, wrist arthroscopy, distal radius open reduction and internal fixation, carpal tunnel release, and thumb carpometacarpal surgery...

BACKGROUND: Suboptimal tibiotalocalcaneal arthrodesis (TTCA) fusion rates may result from inadequate compression that increases motion and interferes with bony bridging. The aim of this study was to evaluate compressive forces at the ankle and subtalar joints with 3 contemporary TTCA constructs. METHODS: Thirty fresh-frozen cadaveric lower extremity specimens were divided into 3 groups of 10 each: 3 partially threaded cannulated screws, hindfoot nail, and lateral plate...

INTRODUCTION: The gastrocnemius muscular flap has already proven its efficiency for soft tissue coverage in cases of knee joint exposure. However, it may be too small to cover large defects and has not the same aesthetic and mechanical properties as normal skin. Perforator fasciocutaneous flaps have recently been described in knee joint coverage with good results as they replace skin by skin, but they can be hard to harvest. Gastrocnemius flaps can be easily harvested with a planned skin paddle designed over the chosen muscle...

REVIEW
Eric So, Matthew D Wilson, Anson K Chu, Mark A Prissel
Hallux interphalangeal joint arthrodesis is an effective procedure to treat pain and provide stability and is often performed for intrinsic pain to the hallux interphalangeal joint. Additionally, this procedure is typically used in concert with the Jones tenosuspension. Although this as an accepted technique, the available data are scant, and questions remain regarding nonunion rates and contributory factors to poor healing. A systematic review of the reported data were undertaken to determine the rate of nonunion for hallux interphalangeal joint arthrodesis...

A 4 mo old German shepherd dog was presented following an acute onset lameness and swelling of the thoracic limb. Clinical signs, surgical findings, and culture results were consistent with a diagnosis of necrotizing fasciitis. Initial management consisted of extensive surgical debridement, wound lavage, and bandaging. Surgical closure was achieved with an axillary fold flap and distant direct single-pedicle thoracoabdominal flap. Three mo later, following deterioration of the lameness that was associated with carpal valgus, carpal subluxation, and tendinopathy of the distal radial insertion of the biceps brachii tendon, a closing wedge pancarpal arthrodesis and tenotomy of the biceps brachii tendon was performed...

REVIEW
Dennis Lee, Nader S Dahdaleh
Charcot spinal arthropathy (CSA) is a rare progressive disorder of vertebral joint degeneration that occurs in the setting of any condition characterized by decreased afferent innervation with loss of deep pain and proprioceptive sensation in the vertebral column. While surgical circumferential arthrodesis remains the most effective treatment modality, it is associated with multiple complications, including hardware construct failure. This manuscript represents an up-to-date narrative review of the treatment of CSA, its associated complications, and complication prevention...

Paul Dayton, Daniel J Hatch, Robert D Santrock, Bret Smith
Although plating on the plantar, tension-side of the metatarsocuneiform joint provides an inherent biomechanical advantage for Lapidus arthrodesis, it has not been widely adopted owing to the morbidity associated with plantar application. To overcome these limitations, a modification to 90-90 locked biplanar plating was developed to provide the biomechanical advantages of multiplanar fixation and tension-side fixation, allowing application through a conventional incision. We tested the hypothesis that biplanar plating with tension-side fixation (low-profile straight dorsal plate and anatomic medial-plantar plate) would demonstrate improved mechanical stability compared with a previously tested 90-90 biplanar construct (small straight plate dorsally and medially) under cyclic loading...

Historically, the postoperative protocol for patients undergoing first metatarsophalangeal joint arthrodesis has included 6 weeks of non-weightbearing, followed by protected weightbearing in a below-the-knee cast boot or postoperative shoe. This prolonged period of non-weightbearing predisposes the patient to disuse atrophy, osteopenia, deep vein thrombosis risk, and, overall, a prolonged time to recovery. The present study reports a retrospective review of a patient cohort that underwent first metatarsophalangeal joint fusion with immediate full weightbearing postoperatively...

Acute native joint septic arthritis is generally considered a surgical emergency, requiring drainage within hours, including during night, weekend or holiday shifts. However, there are few data supporting the need for the disruption caused by this degree of urgency. METHODS: We performed a retrospective review of all adult patients seen in our medical center from 1997-2015 with culture-proven septic arthritis and noted the epidemiology of sequelae, and their possible association with a delay in surgical drainage...
