    ABSTRACT: Granular cell tumor of peripheral nerves is extremely rare. We present the case of a patient with a well-capsulated intraneural granular cell tumor involving the posterior tibial nerve, who presented with chronic heel pain mimicking plantar fasciitis. Magnetic resonance imaging revealed a well-defined intraneural soft-tissue mass within the substance of the posterior tibial nerve. Histopathologic examination showed a granular cell tumor, which is extremely rare in the peripheral nerves. Heel pain is one of the common conditions handled by physicians, podiatrists, and orthopedic surgeons. Posterior tibial nerve lesions at the leg should be kept in mind in the differential diagnosis of patients with persistent heel and foot pain. Magnetic resonance imaging is a useful method in the anatomical evaluation of focal intraneural lesions.

    ABSTRACT: Lipoma arborescens is an uncommon pseudotumoral synovial lesion usually located in the suprapatellar pouch of the knee. Lipoma arborescens involving the synovial sheaths of the tendons is exceedingly rare. This diagnosis should be considered, particularly in patients with chronic joint effusion. We report a case with lipoma arborescens affecting the synovial sheaths of the peroneal tendons without involvement of the adjacent ankle joint. To our knowledge, this is the second reported case of lipoma arborescens involving tenosynovial sheaths of tendons around the ankle joint without ankle joint involvment.

    ABSTRACT: Locking loops are invented to prevent pull-out complication during early active rehabilitation after flexor tendon repair. This study compares the mechanical properties of the side-locking modified Kessler repairs with four- and two- side locking points. Twenty fresh flexor digitorum profundus tendons of the healthy adult sheep forelimbs were sutured by the two-strand modified Kessler with the side-locking loop technique (group A: four locking points), and by the two-strand modified Kessler repair method with a side locking knot on the opposite corners of the repair (group B: two locking points). To assess the mechanical performance of the repairs, the tendons were subjected to a linear non-cyclic load-to-failure test using a material testing machine. Outcome measures included the 2.0 mm gap force at the tendon ends, the ultimate forces and the mode of failure. The mean value for the 2.0 mm gap strength was 19.2+/-1.4 for group A and 19.3+/-1.9 for group B. The mean value of the failure strength was 33.1+/-2.6 for group A and 29.8+/-3.2 for group B. Regarding the 2.0 mm gap strength between the tendon ends, no significant difference was observed between the two groups. There were statistically significant differences in failure strengths of the two groups (p=0.019). As regards the mode of failure, no suture pull-out was observed. All the specimens failed due to suture breakage at the repair site. Results of this study revealed that gap formation and suture pull-out can be prevented using single side locking points on the opposite corners of the modified Kessler repair.

    ABSTRACT: Femoral nerve compression due to a cystic lesion around the hip joint is rare and only a few cases have been described in the literature. Among these, true ganglion cysts are even more rare. We report the case of a 57-year-old woman with femoral nerve compression caused by a true ganglion cyst of the hip joint. A high index of suspicion is required to predict a non-palpable cystic lesion around the hip joint as it may mimic different disorders and should be kept in mind in the differential diagnosis of unusual groin pain, radicular pain and peripheral vascular disorders.

    ABSTRACT: We report here an 11-year-old previously healthy girl with isoniazid intoxication who sustained a seizure-induced thoracic compression fracture. The following might be the first such case reported in the medical literature. Isoniazid toxicity should be suspected in any patient who comes to the emergency department with refractory seizures and metabolic acidosis. Forceful muscle contractions during a convulsive seizure can result in vertebral compression fracture, especially in the midthoracic region. A complaint of back pain after isoniazid-induced seizures in patients raises a strong suspicion of vertebral fracture and should be evaluated radiologically.

    ABSTRACT: This study compares the mechanical properties of modified Kessler and double-modified Kessler flexor tendon repair techniques and evaluates simple modifications on both methods. Forty fresh sheep flexor tendons were divided equally into four groups. A transverse sharp cut was done in the middle of each tendon and then repaired with modified Kessler technique, modified Kessler with additional purchase point in the midpoint of each longitudinal strand, double-modified Kessler technique, or a combination of outer Kessler and inner cruciate configuration based on double-modified Kessler technique. The tendons were tested in a tensile testing machine to assess the mechanical performance of the repairs. Outcome measures included gap formation and ultimate forces. The gap strengths of the double-modified Kessler technique (30.85 N, SD 1.90) and double-modified Kessler technique with inner cruciate configuration (33.60 N, SD 4.64) were statistically significantly greater than that of the two-strand modified Kessler (22.56 N, SD 3.44) and modified Kessler with additional purchase configuration (21.75 N, SD 4.03; Tukey honestly significant difference test, P < 0.000). There were statistically significant differences in failure strengths of the all groups (analysis of variance, P < 0.000). With an identical number of strands, the gap formation and ultimate forces of the repairs were not changed by additional locking purchase point in modified Kessler repair or changing the inner strand configuration in double-modified Kessler repair. The results of this study show that the number of strands across the repair site together with the number of locking loops clearly affects the strength of the repair; meanwhile, the longitudinal strand orientation and number of purchase points in a single loop did not affect its strength.

    ABSTRACT: Insufficiency fractures of femoral necks due to osteoporosis of unknown aetiology occurring coincidentally on both sides in young adults, have not been described in English literature so far. A 18-year-old young girl presented with a 3-month history of gradual onset of bilateral thigh pain and progressive inability to walk. At the first look, plain radiographs of both hips showed no gross abnormal findings other than some tips on reduced bone mineral density of the femoral necks. MRI was ordered upon a high suspicion of fracture and T1-weighed MRI showed a linear low signal on both femoral necks. Dual-energy X-ray absorptiometry of the lumbar spine and femoral neck showed low mineral density. She was treated surgically with in-situ internal fixation using cannulated screws. The bilateral thigh pain was resolved and walking started immediately after the treatment. Insufficiency fracture of the femoral neck due to osteoporosis should be kept in mind even in young adults complaining of atypical pain without evidence of unusual activities. We used both the terms of stress fracture and insufficiency (osteoporotic) fracture interchangeably as the mechanism of fractures resemble each other.

    ABSTRACT: The authors report on an 81-year-old woman with a primary hydatid cyst located in the posteromedial aspect of the thigh. She presented with sciatica, and the cyst was also associated with neurological dysfunction because of its intra-neural location. Diagnosis of a cyst in a nerve body is very rare, and the one reported here might be the first such case. So far, in all the previously reported cases in which there were also neurological findings, the cysts in the vertebral column were compressing the spinal cord or there was an intrapelvic mass compressing the sciatic nerve. Hydatid cyst should be considered in the differential diagnosis of sciatica, especially when treating patients who live in or have emigrated from areas of the world where Echinococcus granulosus is prevalent.

    ABSTRACT: Hemangiomas of the median nerve are very rare and, so far, only ten cases of intraneural hemangioma of this nerve have been reported in the literature. We present a case of 14-year-old girl who had a soft tissue mass in the region of the left wrist with signs and symptoms of carpal tunnel syndrome. Total removal of the mass was achieved using microsurgical epineural and interfasicular dissection. The symptoms were relieved completely, after this procedure, without any neurologic deficit. On follow-up two years later, no recurrence was observed. Whenever a child or young adult patient presents with CTS the possibility of a hemangioma involving the median nerve should be kept in mind in the differential diagnosis.

    ABSTRACT: BACKGROUNd: To determine the effectiveness of four different local injection modalities in the treatment of plantar fasciitis. In a prospective randomized multicenter study of plantar fasciitis, 100 patients were divided into four equal groups and were treated using four different methods of local injection: group A was treated with 2 mL of autologous blood alone; group B, an anesthetic (2 mL of lidocaine) combined with peppering; group C, a corticosteroid (2 mL of triamcinolone) alone; and group D, a corticosteroid (2 mL of triamcinolone) combined with peppering. The outcome was defined by using a 10-cm visual analog scale and modified criteria of the Roles and Maudsley score 3 weeks and 6 months after the injection and compared with the pretreatment condition. The successful results in all of the groups after injections were higher than those in the pretreatment condition (P = .000). In groups C and D, in which local corticosteroid injections were used, excellent results were obtained, with superior effect in the group in which peppering was used (P < .05). In the treatment of plantar fasciitis, combined corticosteroid injections and peppering is effective and produces better clinical results.
