Bizarre Parosteal Osteochondromatous Proliferation (Nora's Lesion) in the Medial Sesamoid of the First Toe.

Bizarre parosteal osteochondromatous proliferation, or Nora's lesion, is a unique bony lesion that generally originates from the small bones of the hands and feet in young adults. We report a case of a bizarre parosteal osteochondromatous proliferation originating from the medial sesamoid of the first toe that was managed surgically by en bloc excision. At 5-year follow-up, there was no evidence of recurrence.

Rice body mass formation mimicking a neoplastic disease around the trochanteric bursae of the hip.

Multiple rice body formation is an uncommon inflammatory process. Sometimes it leads to a big mass in unusual locations. Although sometimes associated with bursitis and systemic diseases, such as rheumatoid arthritis, the pathophysiology of this rare entity is still obscure.

Arthroscopic treatment of synovial chondromatosis of the ankle.

We report a case of synovial chondromatosis of the ankle joint, which has been successfully treated with arthroscopic removal of loose bodies and synovectomy, with the patient immediately returning to school and activities of daily living. Recovery after arthroscopic debridement and loose body removal is much shorter in comparison with arthrotomy, and there is no need of immobilization postoperatively.

Three-bundle popliteus tendon: a nonsymptomatic anatomical variation.

A 34-year-old man suffering from knee pain on the medial side of his right knee underwent knee arthroscopy. The arthroscopy revealed the popliteus tendon with an appearance of three bundles. Three-bundle popliteus tendon is a normal variant finding with no clinical significance.

A complete supra-patellar plica with an unusual presentation.

A suprapatellar plica is a persistent remnant of the embryologic synovial membrane between the suprapatellar pouch and the knee joint. Pathologic synovial plica is not a common entity, however, when present, it can mimic a variety of clinical situations. We describe here a case of pathologic suprapatellar plica that has a check-valve mechanism, which results in a clinical presentation as knee joint swelling.

Bilateral lipoma arborescens of the knee in a child: a case report.

We report a case of childhood lipoma arborescens of both knee joints who had been erroneously diagnosed to have initially acute rheumatic fever and subsequently oligoarticular juvenile rheumatoid arthritis. She had taken anti-inflammatory medication for 8 years without remission of the effusion. Magnetic resonance imaging (MRI) and synovectomy revealed the diagnosis of lipoma arborescens.

Decrease in the numbers of mechanoreceptors in rabbit ACL: the effects of ageing.

It is proposed that there is a positive correlation between the numbers of mechanoreceptors and proprioceptive function. On the other hand, normal aging process is associated with deficits in proprioception. This study is designed to test the hypothesis that aging resulted in decreased numbers of mechanoreceptors.

The effects of menstrual cycle on the knee joint position sense: preliminary study.

The purpose of this study was to determine the effects of menstrual cycle on proprioception by using the active knee joint position sense test (JPST). The 19 healthy women (ages between 20 years and 27 years) who have normal regular menstrual cycle were included in the study. We applied JPSTs at two different directions throughout the three different phases of the menstrual cycle, i.

Type Of Study: Prospective, longitudinal study.

Methods: Between August 2001 and December 2001, we prospectively evaluated 50 consecutive patients (37 male, 13 female) with 65 pathologies of medial meniscal tears, lateral meniscal tears, and/or ACL rupture.

The sole arch indices of adolescent basketball players.

Objective: The aim of this study was to find out the difference between sole arch indices of adolescent basketball players and an age matched non-athletic group.

Methods: This study was carried out in the Sports Education, Health and Research Center, Ankara, Turkey, between November 1998 and December 1998. In junior (16-18 years) categories 48 male basketball players and 45 age matched controls were included in the study.

[Patellar instability: arthroscopic surgery, indications and techniques].

A significant incidence of knee pain and disability arises from patellofemoral disorders. An accurate diagnosis relies both on a comprehensive history and a careful physical examination; radiologic modalities also play an important part in the diagnosis and follow-up. Most patellofemoral disorders can be examined in three groups: pain due to soft tissue abnormalities, patellar instability, and patellofemoral osteoarthritis.

[Wrist injuries in children and adolescent athletes: macrotrauma and overuse].

Young children and adolescents are becoming increasingly involved in recreational and professional sports. This inevitably leads to an increase in the number of sports-related injuries involving the hand and the wrist. Hence, physicians should have a good insight into macro- and microtraumas affecting the hand and the wrist.

Influence of irrigation solutions combined with colchicine and diclofenac sodium on articular cartilage in a rat model.

A two stage, controlled animal trial was designed to observe the effects on normal and manually damaged articular cartilage of the rat knee joint of colchicine (COL) and diclofenac sodium (DIC) added into washout solutions. In the first stage, 21 rats were randomized into three groups, and right knees of all groups were washed-out by either COL, DIC or physiologic saline (PS) solutions. The left side was kept as a paired control.

The efficacy of intra-articular ketamine for postoperative analgesia in outpatient arthroscopic surgery.

Purpose: The purpose of this study was to compare the postoperative analgesic effects of intra-articularly administered ketamine, neostigmine, and bupivacaine after outpatient arthroscopic surgery.

Type Of Study: Prospective, randomized, double-blind, clinical study.

Methods: In this study, 60 patients undergoing arthroscopic surgery other than ligament reconstruction were evaluated for postoperative pain.

Cervical and lumbar spinal changes diagnosed in four-view radiographs of 732 military pilots.

Background: Pilots who fly jet fighters or helicopters frequently experience vertebral problems due to acceleration and vibration, wearing helmets and other headgear, and sitting in suboptimal postures.

Methods: We looked for spondylarthritic or spondylitic changes in 4-view radiographs (AP, lateral, left and right oblique) of the cervical and lumbar vertebrae of 732 pilots and 202 non-flying controls. The subjects included 91 F-16 jet pilots, 363 other jet pilots, 119 transport pilots, and 159 helicopter pilots.

Biomechanical testing of hamstring graft tibial tunnel fixation with bioabsorbable interference screws.

Purpose: This study evaluated the failure mode, maximum load at failure, displacement at failure, and stiffness differences of quadrupled hamstring graft-tibial tunnel fixation using 28-mm, tapered 35-mm, or bicortical 17- and 20-mm bioabsorbable interference screws (Arthrex, Naples, FL).

Type Of Study: Biomechanical study.

Partial deficiency of the lateral meniscus.

We report an abnormally shaped lateral meniscus. As far as we know, the present case is the first description of partial deficiency of the lateral meniscus in the literature. Although it is a rare abnormality, arthroscopic surgeons should be familiar with this entity for the differential diagnosis of bucket-handle meniscal tears, not only for magnetic resonance imaging, but also for arthroscopic evaluation.
