Fractures due to hypocalcemic convulsion

Abstract We report on two cases of patients in whom hypocalcemic seizures during hemodialysis led to right scapular body fracture in one and bilateral femoral neck fractures in the other.Résumé Nous présentons deux cas, chez les quelles on a rencontrés une fracture de l’omoplate dans l’un, et une fracture des cols femoraux bilateraux dans l’autre, à cause des convulsions hypocalcémiques pendant l’hemodialise.

Dysplasia Epiphysealis Hemimelica of the Ankle Joint: A Case Report:

Dysplasia epiphysealis hemimelica is a rare non-hereditary epiphyseal disease that mimics synovial chondromatosis of the joints. The disease mainly targets long bones of the lower extremities and tarsal bones. We report one such case manifesting in the lateral tibia of a 13-year-old boy. He presented with a 7-month history of pain and a bony mass (3×4 cm) at the right ankle. The mass restricted ankle dorsiflexion over the lateral malleolar area. It was ossific with a lobulated appearance and reached the marrow with the underlying epiphysis and adjacent bones. The mass was excised completely from the epiphysis. The detached syndesmos was sutured anatomically.

Correlation of basic motor skills with arthroscopic experience

OBJECTIVES One of the methods in motor skill teaching is to furnish the students with the individual skills drawn from the target procedure. This method requires identification and defining of all components of the target procedure. This study aimed to define basic motor skills composing arthroscopic skillfulness. METHODS A total of 42 orthopedists (mean age 38+/-8 years) were enrolled. The study group was comprised of 17 experienced orthopedists working at least for 10 years as a specialist and performing more than 50 arthroscopic procedures per year. The control group included 25 young orthopedists or residents having an arthroscopic experience of less than three years. All the participants were assessed simultaneously and in the same experimental setting. Each participant was tested after having been shown to use in vitro skill development instruments simulating arthroscopic basic motor skills. RESULTS Compared to the control group, the experienced group had significantly higher mean age (42 vs. 34.4 years), longer duration of arthroscopic experience (12.4 vs. 1.6 years), and greater number of the arthroscopies performed per year (93.9 vs. 26.9) (p=0.000). The mean anticipation time (p=0.028) and two-arm coordination time (p=0.043) were significantly shorter in the experienced group. In correlation analysis, duration of arthroscopic experience was correlated with the mean anticipation time (r=-0.41, p=0.008) and two-arm coordination time (r=-0.33, p=0.033). In addition, the mean anticipation time decreased significantly as the number of arthroscopies increased (r=-0.446, p=0.003). CONCLUSION Some basic motor skills correlate with arthroscopic competence. The use of these motor skill instruments in arthroscopy training may aid to improve arthroscopic skills.

Trevor’s disease: mimicking anterior ankle impingement syndrome: case report

AbstractThis report concerns an unusual cause of anterior ankle impingement. The case of a young male with Trevor’s disease mimicking an anterior spur of the ankle that resulted in anterior impingement and treated with ankle arthroscopy is presented. The aim of this study is to explain the different diagnostic properties of Trevor’s disease from a classic anterior spur. Level of evidence IV.

Solitary osteochondroma of ischial ramus causing sciatic nerve compression.

We present a 25-year-old male case of osteochondroma originating from ischial ramus which causes sciatica. The pelvic involvement is rare. Iliac crest of the pelvis is often involved. Ischial ramus involvement is extremely rare. In this article, we presented a rare case of ischial ramus involvement that misleading the physician to L4-L5-S1 radiculopathy.

Cavernous hemangioma behaving like peroneal tenosynovitis.

Hemangioma of the tendon sheath is rarely reported. In this case report, a 22-year-old man, who had been seen for peroneal tenosynovitis before (although symptoms remained) was reevaluated. A cavernous hemangioma was located in the peroneal muscle and the tendon. Complete excision was performed.

Myositis ossificans circumscripta, secondary to high-velocity gunshot and fragment wound that causes sciatica.

This report concerns an unusual cause of sciatica. The case presented is of a young man with myositis ossificans that resulted in sciatica and was treated with en bloc excision and low-dose radiotherapy and indomethacine. The aim of this study was to explain the different diagnostic properties of myositis ossificans around the hip and non-classic causes of sciatica.

Limited distal clavicle excision of acromioclavicular joint osteoarthritis.

INTRODUCTION Resection of the distal aspect of clavicle has a well-documented treatment modality in case of acromioclavicular joint osteoarthritis resistant to conservative treatment. HYPOTHESIS Limited (mean ∼0.5cm distal end of clavicle resection) distal clavicle excision of A-C joint arthritis in cases resistant to conservative treatment may reduce the pain and improve the shoulder function. MATERIAL AND METHODS In this study, we retrospectively evaluated the results of limited distal clavicle excision of acromioclavicular joint osteoarthritis resistant to conservative treatment. All patients were evaluated by using the Visual Analogue Scale (VAS) and UCLA shoulder rating scale (University of California Los Angeles), either before surgery or final follow-up period for pain and functional results, respectively. RESULTS A total of 110 patients (48 male, 62 female) with AC joint arthritis, treated between the years of 2008-2012, were retrospectively analyzed. A total of 30 patients (12 male, 18 female) who failed to show improvement with conservative treatment underwent limited surgical open excision of distal clavicle. The mean age of the study population was 52.5±1.2 years. The mean follow-up period was 27±1.3 months. The mean preoperative VAS score was 83.6±5.58 (range, 70-90) while mean VAS was 26.6±9.3 (range, 10-50) at the final follow-up. There was a statistically significant difference between pre- and postoperative VAS scores in patients who had treated by surgical approach (P<0.001). The mean UCLA score of the patients increased postoperatively from 11.5 (range, 9-14) to 29.2 (range, 27-32) at the final follow-up. There was a statistically significant difference between the two time periods with respect to UCLA scores (P<0.001). DISCUSSION AND CONCLUSION In patients with AC osteoarthritis resistant to conservative therapy, the hypothesized limited clavicle excision (mean ∼0.5cm distal end of clavicle resection with preserving coracoclavicular ligaments and inferior capsule) reduced the pain and improved the shoulder function. CONCLUSION Our midterm follow-up (mean 27 months) results showed that limited distal clavicle excision of patients with AC joint osteoarthritis resistant to conservative treatment (0.5cm distal end of clavicle resection with preserving inferior capsule, and coracoclavicular ligaments) reduced the pain and improved the shoulder function. LEVEL OF EVIDENCE IV (Retrospective study).

Degenerative arthritis of pseudoarticulation between the os peroneum and cuboid: A rare cause of lateral foot pain

The painful os peroneum syndrome is widely recognized. It is often the result of trauma. However degenerative changes between the os peroneum and the articular facet is much rarer and we could only find two other case reports in the literature. This report concerns a middle aged woman with chronic plantar-lateral foot pain and a limp secondary to degenerative changes between the os peroneum and its articular facet with cuboid. The aim of this study is to remind to orthopaedic surgeons about painful os peroneum syndrome and to highlight the rarity of our case. In our case the mid term result of the excision of the os peroneum with painful articulation appear good, providing symptomatic pain relief with little alteration in the function of the foot.

Solitary synovial osteochondroma of the knee: mimicking a giant loose body

Solitary synovial osteochondromas are rarely seen. Usually arising from the juxta-articular soft tissues without attaching to the bone, these lesions can be large and show clinical and radiological features of a malignant process. This report is about a 64-year-old woman with no history of trauma. She had a history of dull pain and a progressive limited range of motion that had been ongoing for 3 years. An unusual presentation of an uncommon disease that is not widely known by orthopedic surgeons is reported.
