Posterolateral rotatory instability of the elbow in the absence of epiphyseal injury is extremely rare in children. We present a case of 12-year-old child in whom recurrent dislocation of the elbow was associated with a stretched lateral ulnar collateral ligament. We performed surgical repair and reefing of a stretched lateral ulnar collateral ligament by using a suture anchor and a continuous locking suture in order to avoid donor site morbidity and damage of the growth plate, which could occur when a transosseous tunnel for reconstruction was made. At 12 months after operation, satisfactory symptom relief was observed with no evidence of recurrence.

Although flexor tendon triggering due to stenosing flexor tenosynovitis is common clinically, extensor triggering is quite rare. Known common causes are impingement between extensor tendon and extensor retinaculum, stenosis of the tendon sheath, and impingement between extensor tendon and osteophyte. We report rare case of triggering in the little finger caused by impingement between extensor digiti minimi and synovial septum.

The alignment of lower extremities is an important consideration in many clinical situations, including fracture reduction, high tibia osteotomy, total knee arthroplasty, and deformity correction. Mal-alignment of lower extremities is not only a simple cosmetic problem, but it can also produce pain, limp, and early degenerative arthritis. An assessment of lower extremity alignment, including its location and magnitude of deformity, can be achieved via mal-alignment test and mal-orientation test, using a lower extremity standing full-length radiography. Proper evaluation allows the surgeon to determine an effective treatment plan for deformity correction.

A traumatic carpometacarpal joint dislocation of the thumb accounts for less than 1% of all hand injuries. Optimal treatment strategies for this injury are still a subject of debate. In this article, we report a case of bilateral thumb carpometacarpal joint dislocations: a unique combination of injuries. We believe our case is the second report of bilateral carpometacarpal joint dislocation regarding the thumb in English literature. It was successfully treated with closed reduction and percutaneous K-wires fixation on one side, and an open reduction and reconstruction of the ligament on the other side.

PURPOSE: The purpose of this study was to investigate the effects of transplantation of an in vitro-generated, scaffold-free, tissue-engineered cartilage tissue analogue (CTA) using a suspension chondrocyte culture in a rabbit growth-arrest model. MATERIALS AND METHODS: We harvested cartilage cells from the articular cartilage of the joints of white rabbits and made a CTA using a suspension culture of 2x107 cells/mL. An animal growth plate defect model was made on the medial side of the proximal tibial growth plate of both tibias of 6-week-old New Zealand white rabbits (n=10). The allogenic CTA was then transplanted onto the right proximal tibial defect. As a control, no implantation was performed on the left-side defect. Plain radiographs and the medial proximal tibial angle were obtained at 1-week intervals for evaluation of bone bridge formation and the degree of angular deformity until postoperative week 6. We performed a histological evaluation using hematoxylin-eosin and Alcian blue staining at postoperative weeks 4 and 6. RESULTS: Radiologic study revealed a median medial proximal tibial angle of 59.0degrees in the control group and 80.0degrees in the CTA group at 6 weeks. In the control group, statistically significant angular deformities were seen 3 weeks after transplantation (p<0.05). On histological examination, the transplanted CTA was maintained in the CTA group at 4 and 6 weeks postoperative. Bone bridge formation was observed in the control group. CONCLUSION: In this study, CTA transplantation minimized deformity in the rabbit growth plate injury model, probably via the attenuation of bone bridge formation.

When hand injuries caused by human bite are overlooked and they can progress to pyogenic arthritis. Pyogenic arthritis is difficult to treat and can make severe sequelae in the joints. We report a case of pyogenic arthritis of the hand that occurred after human bite injury in adolescent treated with wide debridement and external fixator. Our literature searches revealed that the use of external fixator is good treatment option for the treatment of pyogenic arthritis of the hand.

STUDY DESIGN: A retrospective study. PURPOSE: To assess the radiological, clinical features and surgical outcomes of six patients of elementary school age with lumbar disc herniation (LDH). OVERVIEW OF LITERATURE: LDH is common in people in their fourth and fifth decades. However, the condition is extremely rare in children of elementary school age. Moreover, the clinical symptoms and treatments are different from those of adults. METHODS: We reviewed a series of 6 patients under the age of 12 years, who underwent surgery for LDH at our institution between 1992-2002. Initially, all patients were treated conservatively. The indications for surgery were failure of conservative treatment for 3 months, intractable pain and/or progressive neurological impairment. RESULTS: The surgical findings revealed a protruding disc in five cases and a ruptured disc in one. In addition, separation of the vertebral ring apophysis was observed in 3 cases. The symptoms had disappeared completely at the last follow-up. At the last follow-up, the Japanese Orthopaedic Association score was 10 points in 5 cases and 9 points in 1, and the Kirkaldy-Willis criteria was excellent in all patients. No intervertebral disc space narrowing was observed in any patient at last follow up. In addition, there were no degenerative changes in the vertebral endplate and facet joint. CONCLUSIONS: Patients with symptoms that persist for more than 3 months or those with a progressive neurological deficit must be considered for surgical discectomy.

We report a dislocation of the thumb carpometacarpal joint associated with an oblique fracture of the trapezium. This case was treated with open reduction and internal fixation using two Kirschner wires for the trapezial fracture and repair of the ruptured dorsal capsular ligament and additional Kirschner wire fixation for the carpometacarpal joint stability. At the 12 months follow-up examination, there was no pain or chronic instability. There was no evidence of post-traumatic arthritic changes.

Popliteal pterygium syndrome is a rare congenital disorder that consists of popliteal webs and craniofacial, genitourinary and extremity anomalies. Only moderate successful surgical excision of the fibrotic band within the popliteal web has been reported because the nerves and vessels in the affected site are short and displaced into the web and they are attached to adjacent tissues. We performed hamstring tenotomy on the ischial tuberosity, tenotomy of the flexor hallucis longus and Z-lengthening of the Achilles tendon on the ankle in our patient, and this was followed by gradual correction using an Ilizarov external fixator. Full extension of the knee joint was achieved at the ninth postoperative week. However, some recurrence of flexion contracture was noted at two years follow-up. Gradual soft tissue lengthening with an Ilizarov external fixator can be one of the optimal procedures when excision of a fibrous band and Z-plasty are not possible due to severe adhesion of the nerves and vessels into a fibrotic band. However, a cautious approach is recommended when considering the high risk of recurrence.
