Compartment syndrome in the hand due to extravasation of contrast material

Extravasation of contrast material is a well-recognized complication of contrast-enhanced imaging studies. Most extravasations result only in minimal swelling or erythema; however, severe skin necrosis, ulceration and compartment syndrome may occur with extravasation of large volumes. This article presents a patient in whom extravasation developed after computed tomography (CT) contrast material was injected intravenously in the dorsum of the hand. Compartment syndrome was diagnosed, and the patient underwent fasciotomy. In follow-up, the patient regained full use of the hand. Although the use of contrast material has significantly improved the diagnostic accuracy of CT, anaphylaxis and contrast material extravasation are important complications. Selection of non-ionic contrast material, careful evaluation of the intravenous administration site and close monitoring of the patient during contrast material injection may help minimize or prevent extravasation injuries.

Opposite-direction bilateral fracture dislocation of the shoulders after an electric shock.

Injuries after an electric shock, such as dermal burns, motor and sensory nerve deficits, fractures and dislocations, are reported in the literature. Posterior dislocation of the shoulder after electric-shock is the common musculoskeletal injury. Bilateral dislocation, either anterior or posterior, is rarely seen and reported. We report a case of bilateral shoulder fracture dislocation in opposite directions following an electric-shock and discuss the mechanism, the diagnosis and the treatment.

Avulsion of the tibial tuberosity with a lateral plateau rim fracture: case report

An avulsion fracture of tibial tuberosity with an unusual articular involvement was treated with open reduction and internal fixation. Although the mechanism of tibial tuberosity fracture is described as passively flexing the knee while active quadriceps femoris contraction, the weight transmitted from the menisci on the lateral side of the knee joint may cause an epiphyseal disruption. We report a case of tibial tuberosity fracture with lateral plateau rim fracture in a young male adolescent, which has not been published previously in the literature.

A clinical case and anatomical study of the innervation supply of the vastus medialis muscle

The innervation supply to the vastus medialis (VM) muscle, a component of quadriceps femoris (QF), is provided by a branch of the femoral nerve (FN) running along the muscle. The course of the nerve from lumbar roots to the muscle has been described by many researchers. It is known to ride along the femoral vein, artery and saphenous nerve and enter the adductor canal (Hunters canal), and then to divide into branches that supply vastus medialis and the knee joint. Femoral mononeuropathy is uncommon, and is usually due to compression in the spinal level. Hematoma in the psoas and iliacus muscles, drug abuse, lithotomy position and limb lengthening are the other associated reasons for a mononeuropathy of the femoral nerve. Isolated vastus lateralis (VL) atrophies have been reported by a few authors, suggesting that compression of the nerve and direct violation of the nerve with injections might be the reason for mononeuropathy. Isolated VM atrophy has not been previously reported. The purpose of the study was to identify the anatomical structures around the FN branch which innervates the VM muscle.

Anatomy of The Posterior Iliac Crest as a Reference to Sacral Bar Insertion

There are no detailed anatomic studies focusing on the posterior iliac crest although it frequently is used for posterior stabilization of unstable pelvic fractures. Anatomic dissections were done to evaluate the size of the extraarticular region of the posterior iliac crest and its relationship to the lumbosacral lamina and to show on cadavers the level of sacral bar placement that offers safe and solid fixation. Sixty cadavers were dissected bilaterally. Fifty-one were male and nine were female. The distance between the posterior wall of the sacral canal and the tip of the iliac crest was measured at various levels between the level of the upper border of L5 lamina to the level of the posterosuperior iliac spine. In all the dissections the greatest distances were at the level of the L5-S1 junction, which consequently is the safest level for good bony purchase. The entire length of the posterior iliac crest from the level of the upper border of L5 lamina to the posterosuperior iliac spine was shown to be appropriate for safe and solid bar fixation because all of the distance measurements were greater than 13 mm, which is the smallest safe distance. Below the posterosuperior iliac spine level, insertion of the sacral bars was dangerous because the average measured distance was only 10.38 mm.

Giant cell tumor of the talar neck.

We describe a patient with a giant cell tumor in the talar head and neck of the left foot who was diagnosed as having osteochondritis dissecans and treated with arthroscopic drilling in this same location 3 years earlier. Giant cell tumors can be confused with several conditions, including giant cell reparative granulomas, brown tumors, and aneurysmal bone cysts. Giant cell tumors of bone typically occur in the epiphysis of long bones, including the distal femur and proximal tibia. They are uncommonly found in the small bones of the foot or ankle, and talar involvement is rare. Despite this rarity, the radiographic appearance and clinical signs of talar lesions should be considered in the differential diagnosis of nontraumatic conditions in the foot.

The impact of proximal fibula fractures in the prognosis of tibial plateau fractures: a novel classification

Fifty-five patients who presented with the complaint of tibia plateau fractures between January 1998 and November 2001 were retrospectively evaluated. The evaluation was based on their treatment modality. Twenty-five conservatively-treated patients (group 1) and 30 surgically-treated patients (group 2) were evaluated. In group 1, seven patients with proximal fibula fractures had lateral hamstring tightness. Five out of these seven patients had concomitant lateral knee pain. Similarly, nine patients with proximal fibula fractures in group 2 had lateral hamstring tightness, and seven patients in the same group suffered from lateral knee pain. The patients with no fibula proximal fracture in both groups had no hamstring tightness or lateral knee pain. The proximal fibula in the knee joint and its anatomical structures are of utmost importance for the anatomical integrity of the knee and its normal functions. The fibula has rich anatomical relations, some of which are important structures of the knee. These anatomical structures and the fibula provide stability of the knee joint and its functions as well as being an important mechanical support to the knee joint. Therefore, the knee joint will receive the negative effects from the pathologies of the bone or soft tissue that may occur in fibula fractures.

Sutureless approach with vein grafts and mesenchymal stem cells in primary nerve repair: Functional and immunohistological results

The aim of this study was to define a sutureless peripheral nerve repair technique with a vein graft and bone marrow‐derived stem cells (BMSC) and compare it to epineural repair.

Evaluation of plantar pressure distributions in patients with anteriorcruciate ligament deficiency: preoperative and postoperative changes

BACKGROUND/AIM Anterior cruciate ligament (ACL) deficiency results in several kinematic changes in the lower extremities. The aim of this study is to define the plantar pressure parameters in ACL-deficient patients and to show the effect of ACL reconstruction on dynamic plantar pressure. MATERIALS AND METHODS Forty patients with unilateral ACL rupture and 40 healthy controls were included in this study. Dynamic plantar pressures of both groups were recorded by the EMED SF-2 system during level walking. Thirteen of the patients who had ACL reconstructions with hamstring autografts (HS group) were reevaluated at an average of 14.5 months following the ACL reconstructions. RESULTS ACL-deficient patients had significantly lower hindfoot (P = 0.007) but higher midfoot pressure values (P = 0.03) on their ipsilateral foot compared to control group subjects. Ipsilateral hindfoot pressures were also found to be significantly lower than those of the contralateral foot (P = 0.001). Hindfoot pressure values of the HS group were increased in postoperative measurements (P = 0.01). CONCLUSION ACL-deficient patients have altered plantar pressure distributions and ACL reconstructions restore these changes to normal. Pedobarography might be used as a practical method for dynamic functional assessment of ACL-deficient patients.
