Management of Hypertrophic non-Union After Isolated Fibular Shaft Fracture With Percutaneous Screw Fixation: A Case Report.

Hypertrophic non-union, after an isolated fibular fracture with intact tibia, is an extremely uncommon complication. The aim of the current study is to present an infrequent case of hypertrophic non-union after an isolated fracture in the proximal diaphysis of fibula which was treated surgically. A 23-year-old male patient presented to our hospital with persistent pain on the lateral aspect of his right leg.

Diastasis of the Pubic Symphysis Without Fall While Horseback Riding: A Case Report.

The purpose of this study was to demonstrate a rare case of pelvic ring injury in a healthy man without a history of high energy damage. A 43-year-old man presented to the emergency with local pain in pubic symphysis and difficulty walking after horseback riding. The patient did not report any fall or injury during this recreational activity, and apart from tachycardia, he was hemodynamically stable with normal blood pressure.

Internal Fixation With Cannulated Screws for Stable Femoral Neck Fractures in High-Risk Patients: Good Clinical Outcomes and Evaluation of Postoperative Complications.

This study aimed to investigate the clinical outcome and the postoperative complications after internal fixation with cannulated screws of stable femoral neck fractures (FNFs) in high-risk patients. A total of 76 patients (mean age 70.11 ± 9.

Comparing CB1 receptor GIRK channel responses to receptor internalization using a kinetic imaging assay.

The type 1 cannabinoid receptor (CB1R) mediates neurotransmitter release and synaptic plasticity in the central nervous system. Endogenous, plant-derived, synthetic cannabinoids bind to CB1R, initiating the inhibitory G-protein (G) and the β-arrestin signaling pathways. Within the G signaling pathway, CB1R activates G protein-gated, inwardly-rectifying potassium (GIRK) channels.

Pure Posterior Native Hip Dislocation Following Low-Energy Injury - a Rare Case Report.

Hip dislocations are traumatic injuries that commonly derive from high energy trauma such as traffic accidents or falls from great heights. In addition, these injuries present an increased incidence after partial or total hip arthroplasty in elderly patients. Associate literature dictates that in case of a native hip dislocation, early reduction is crucial for avoidance of further complications such as avascular necrosis of the femoral head and post traumatic arthritis.

Vitamin D Deficiency in Patients With Low-Energy Hip Fractures in Accordance With the Mediterranean Paradox.

Introduction Vitamin D deficiency (VDD) is considered one of the leading causes of poor bone quality. It may also be related to severe muscular weakness, especially in the elderly, which leads to frequent falls. Thus, VDD might be associated with fragility fractures of the hip, wrist, and spine in this age category.

Delayed Presentation of Acute Compartment Syndrome After Isolated Closed Fibular Shaft Fracture: A Case Report.

Post-traumatic compartment syndrome in the lower extremity has been commonly associated with fractures of the tibia. Only in rare cases, this critical condition might be related to isolated fibular fractures. We present a rare case of delayed onset of acute compartment syndrome after a solitary fracture of the fibula.

Conservative Treatment of Isolated Dorsal Dislocations of Fourth and Fifth Carpometacarpal Joints: A Report of a Rare Case.

Carpometacarpal (CMC) dislocations without associated fractures of the adjacent bones are extremely infrequent injuries. Dorsal or volar dislocations occur after high-energy injuries and may lead to early post-traumatic arthritis and carpal instability. The purpose of this study was to present a case of dorsal dislocation of both the fourth and fifth CMC joints that were treated with closed reduction and casting.

Femoral-shaft fractures and nonunions treated with intramedullary nails: the role of dynamisation.

Dynamisation of a previously interlocked intramedullary nail is believed to stimulate an osteogenic response due to increased load across the fracture site. The purpose of this study was to retrospectively investigate fracture patterns that could tolerate dynamisation without the risk of major complications. Thirty patients (24 males) with an average age of 33 years (17-90) were studied.

Apoptosis bcl-2 and nitrotyrosine expression in an angioplasty-restenosis rabbit: an experimental model.

Apoptosis has been suggested to have an important role in the pathogenesis of restenosis in addition to cell migration and proliferation. The aim of the present study was to investigate in an experimental in vivo model the occurrence of apoptosis postangioplasty and its relation to bcl-2 and peroxynitrite detection. Eighteen hypercholesterolemic rabbits underwent transluminal angioplasty of the right iliac artery.

Medial brachial and antebrachial cutaneous nerve injuries: effect on outcome in revision cubital tunnel surgery.

Twenty patients with persistent symptoms of medial elbow pain after previous cubital tunnel surgery were evaluated during reoperation, for injury of the medial antebrachial and medial brachial cutaneous nerves at the time of reoperation. Abnormalities of the medial cutaneous nerves were found in 65 percent of the patients. A neuroma was found in 40 percent of the patients.

An allograft salvage technique for failure of the Darrach procedure: a report of four cases.

We report on four patients with failed resections of the distal ulna causing instability and impingement, who were treated with a tendon allograft to stabilize and buffer the ulnar stump. In three of the four patients the outcome was excellent. We believe that this new technique holds promise as an alternative salvage procedure for the failed Darrach resection.

Evaluating and treating the stiff elbow.

The evaluation and treatment of the stiff elbow are described, as well as the lateral, medial, anterior, and posterior approaches for release of elbow contractures. The results after surgical release in 48 patients that failed nonoperative treatment for elbow contractures in our institution are reported. A literature review is provided.

Minimal medial epicondylectomy and decompression for cubital tunnel syndrome.

Sixty-four patients (66 elbows) treated for refractory cubital tunnel syndrome had minimal medial epicondylectomy and in situ decompression to minimize the potential disadvantages of classic medial epicondylectomy. After a mean followup of 27 months results were excellent in 27 patients (44%), good in 23 patients (35%), fair in 10 patients (15%), and poor in four patients (6%). No ulnar nerve palsy, ulnar nerve subluxation, or medial elbow instability were seen.

Partial rupture of the distal biceps tendon.

We report on 7 cases of partial rupture of the distal biceps tendon. The mean patient age was 52 years (range, 38-58 years). There were 5 men and 2 women.

Treatment of recurrent compressive neuropathy of peripheral nerves in the upper extremity with an autologous vein insulator.

The treatment of entrapment neuropathy in the upper extremity with surgical decompression has generally provided good results. Recurrence of symptoms, however, is not uncommon and its management is both challenging and difficult. Nineteen patients with recurrent carpal tunnel and cubital tunnel syndrome were treated with the vein wrapping technique using the autogenous saphenous vein.

Findings of exploration of a vein-wrapped ulnar nerve: report of a case.

A 54-year-old woman underwent a revision procedure after failure of 3 previous procedures for recalcitrant cubital tunnel syndrome. She underwent neurolysis and vein wrapping of the ulnar nerve during the fourth procedure. Two years later she developed a neuroma of the medial antebrachial cutaneous nerve necessitating a fifth procedure.

The Compass Elbow Hinge: indications and initial results.

The Compass Elbow Hinge uses Illizarov's methods of fixation to externally hold the elbow reduced and allow both passive and active motion. Eleven patients with degenerative disease, contracture or instability were treated with the Compass Elbow Hinge and were retrospectively evaluated at an average follow-up of 29 months (range: 18-62 months). One was lost to follow-up.

Ulnar nerve elongation and excursion in the cubital tunnel after decompression and anterior transposition.

We studied the elongation and excursion of cadaveric ulnar nerves during elbow flexion in control conditions and after in situ decompression and anterior subcutaneous transposition. We found that the normal nerve had the greatest elongation (23%) and excursion (14 mm) in the epicondylar groove. Decompression did not alter the excursion, but significantly reduced the elongation in the groove (6%) and increased it proximally (19%).

Recurrent compressive neuropathy of the median nerve at the wrist: treatment with autogenous saphenous vein wrapping.

Recurrence of symptoms occurs in a significant number of patients after surgical decompression for carpal tunnel syndrome, and its management is both challenging and difficult. Fifteen patients with recurrent carpal tunnel syndrome were treated with a vein wrapping technique using the autologous saphenous vein. A total of 48 operations had been performed on these patients before wrapping the median nerve with a saphenous vein graft.

External beam irradiation following balloon angioplasty in an atherosclerotic rabbit model.

Purpose: To study the effect of external beam irradiation on the morphometry of both angioplasted and nonangioplasted arteries in a hypercholesterolemic rabbit model.

Methods And Materials: Four groups of rabbit femoral arteries were studied: arteries (a) with no intervention, (b) irradiated with a 12-Gy x-ray dose, (c) treated with balloon angioplasty, and (d) dosed with 12 Gy 30 min after balloon angioplasty.

Results: External irradiation did not change vessel morphometry in nonangioplasted arteries.
