PURPOSE: Isolated greater trochanteric (GT) fractures are often identified using plain radiography of patients with post-traumatic hip pain. In many cases, the fracture extends to form an occult intertrochanteric fracture. We conducted a study to determine the frequency of occult intertrochanteric fractures in patients diagnosed with isolated GT fractures using plain radiographs. MATERIALS AND METHODS: Among 3,017 individuals who visited our emergency department with a trauma-induced pertrochanteric femur fracture between July 2004 and March 2018, 100 patients diagnosed with isolated GT fractures using plain radiographs were retrospectively analyzed. Patients were divided into two groups, those with: i) isolated GT fractures (group A) and ii) occult intertrochanteric fractures (group B). In addition, plain radiographs, magnetic resonance imaging results, and treatment methods were further analyzed in each group. If surgery treatment was needed, it was performed by one surgeon, and in all cases, a 2-hole dynamic hip screw was used. RESULTS: Among the 100 cases of isolated GT fractures diagnosed using plain radiograph, additional examinations revealed that 10 (10.0%) were suffering from isolated GT fractures alone, while the remaining 90 (90.0%) were further diagnosed with occult intertrochanteric fracture. Gender, age, mechanism of injury, and bone mineral density did not correlate with fracture type. CONCLUSION: In our analysis, 90% of injuries initially diagnosed as isolated GT fractures were found to extend into occult intertrochanteric fractures upon further examination with additional imaging modalities. Therefore, additional evaluation should be performed to test for the potential presence of occult intertrochanteric fractures and to establish appropriate treatment plans.

Antibiotic cement-coated intramedullary nails maintain a locally high antibiotic concentration while contributing to bone stability. We present a case of femoral subtrochanteric fracture in a patient with an infected nonunion who was successfully treated for an infection and nonunion using an antibiotic cement-coated tibial intramedullary nail. A 79-year-old woman with a right femoral subtrochanteric fracture underwent internal fixation using proximal femoral nail antirotation (PFNA). She developed osteomyelitis with nonunion at the surgical site 10 months postoperatively. We decided to insert an antibiotic cement-coated tibial intramedullary nail. After coating the nail with bone cement mixed with antibiotics, bone fixation was achieved by inserting the nail at the site of the PFNA. The patient's symptoms improved, symptoms from the infection disappeared, and bone union was confirmed. Osteomyelitis occurred because of postoperative infection following a proximal femoral fracture. Antibiotic cement-coated tibial intramedullary nails are an effective option to treat patients with osteomyelitis of the femur and achieve bone union where nonunion persists with shallow a intramedullary femoral canal.

PURPOSE: The purpose of current study is to evaluate the midterm results of cementless primary total hip arthroplasty (THA) using a dual offset titanium tapered stem. MATERIALS AND METHODS: A retrospective analysis of 102 cases (84 patients), with a minimum of 7-year clinical follow-up, was performed. All of the cases consisted of patients who underwent primary cementless THA, using a dual offset titanium tapered stem in The Catholic University of Korea, Bucheon St. Mary's Hospital between July 2004 and May 2009. Clinical results were analyzed via the Harris hip score, level of thigh pain, squeaking around hip joint, and complication rate. Radiologic results were examined with stability and location of inserted prosthesis, hypertrophy of femoral cortex, and osteolysis. RESULTS: Out of the 102 cases (84 patients; 47 males and 37 females), with the mean age of 55.9 years (range, 27–79 years) and mean follow-up period of 99.2 months (range, 84–132 months). The mean Harris hip score was 53.8 preoperatively (range, 26–75) and improved to 93.5 postoperatively (range, 74–100) (p=0.000). All of the cases gained stable bony fixation on the final follow-up, including 2 cases of intra-operative proximal femur fracture. Calcar remodeling was observed in 94 cases, however, they were irrelevant with stem stability. Cortical hypertrophy of femur was seen in 12 cases and thigh pain in 4 cases; nonetheless, they were not relevant (p=0.067). There was 1 case of squeaking sound during joint movement. Hip dislocation occurred in 1 case early after the procedure, but the event was due to excessive anteversion of the acetabular cup, in which a revisional replacement procedure of the acetabular cup was conducted. No sign of ceramic breakage was observed. There were 2 cases of heterotrophic ossification. CONCLUSION: Results from a 7-year follow-up of cementless THA using dual offset titanium tapered stem were encouraging in both clinical and radiologic evaluations.

PURPOSE: The purpose of this study is to evaluate the postoperative outcomes of elderly patients with stable 2-part intertrochanteric femur fractures surgically treated using dynamic hip screw with 2-hole side plate. MATERIALS AND METHODS: From February 2008 to January 2014, 50 patients older than the age of 65 years, who had been followed-up for more than 6 months after the operation at The Catholic University of Korea, Bucheon St. Mary's Hospital were enrolled. A clinical evaluation of the skin incision length, operating time, and ambulatory status, using Clawson's Ambulation Capacity Classification, was performed, and a radiologic evaluation of Fogagnolo reduction quality, tip-apex distance (TAD), Cleveland index, sliding extent of lag screws, time duration till bony union, and complications was also done. RESULTS: The mean skin incision length was 9.8 cm (range, 8-13 cm), the mean operating time was 41.4 minutes (range, 30-60 minutes), and 32 patients recovered their ambulatory function. Forty-eight patients gained bony union, and the time lapsed till union was average 10.6 weeks (range, 8-16 weeks). The evaluation of postoperative radiologic images showed the following reduction statuses by the Fogagnolo classification: 46 cases of "Good", 3 cases of "Acceptable," and 1 case of "Poor." Moreover, the mean TAD was 18.9 mm (range, 9.0-24.9 mm). While 45 cases fit into the zone 5 of the Cleveland index, other 3 were within zone 8 and the other 2 were within zone 6. The mean sliding length of the lag screws were 4.9 mm (range, 0.1-19.4 mm). There were a case of nonunion and a case of periprosthetic infection with nonunion as complications. CONCLUSION: Using dynamic hip screws with 2-hole side plate for stable 2-part intertrochanteric femur fractures in elderly patients showed satisfactory results with respect to the recovery of ambulatory functions and bony union.

Entrapment of the extensor pollicis longus tendon is reported rarely on Smith's fractures in children. In our case, a 15 year old boy with Smith's fracture received treatment of closed reduction at another hospital. When he visited our hospital, a wide gap at the fracture site was detected on radiograph and the thumb movement was limited. We have doubt the entrapment of the soft tissue, especially the tendon. We decided on open reduction. In the operation field, entrapment of the extensor pollicis longus tendon at the gap of the fracture site was found through dorsal approach. In addition, fracture treatment with K-wire fixation after reduction of extensonr pollicis longus tendon reduction was done. Therefore, we report this case with a review of the literatures.

Thoracic outlet syndrome is a relatively common disease. However, costoclavicular syndrome as a condition secondary to nonunion of a displaced fracture of the clavicle is very rare. Most clavicular fractures in adults are united with no or minimal persistent symptoms. Also, symptomatic nonunion of a displaced fracture of the clavicle is rare. A 55-year-old male initially presented with persistent forearm pain after slip-down was initially diagnosed with simple muscle strain. However, he was given a delayed diagnosis of costoclavicular syndrome, caused by compression of the subclavian artery due to trauma in the fibrotic nonunion of the right clavicle without apparent symptoms. We obtained satisfactory results by surgical treatment. Here we report this case with a review of the literature.

Parosteal lipoma is a rare kind of lipoma that occurring adipous tissue around the periosteum. It has been reported most commonly in the femur, the radius, the tibia and the fibular. Treatment consists of resecting the lipomatous tumor with further exeresis of the bone and periosteal excrescence in cases with hyperostosis. The authors report a rare case of parosteal lipoma occurring at the medial portion of the femur shaft with a review of the relevant literatures.

PURPOSE: The purpose of this study is to evaluate the clinical results of retrograde intramedullary fixation of metacarpal shaft fractures using two pre-bent Kirschner wires. MATERIALS AND METHODS: Between March 2006 and May 2008, 19 cases (17 patients) of metacarpal shaft fractures were treated with the retrograde intramedullary Kirschner-wire fixation and followed at least one year. The exclusion criteria were thumb metacarpal fractures, comminuted fractures and irreducible metacarpal spiral shaft fracture by closed manipulation. At final follow up all the cases were assessed with total active motion(TAM), rotational deformity, bony union and angular deformity based on the plain radiographes. RESULTS: At the last follow-up, all cases achieved bony union. Five cases showed less than 5degrees of dorsal angular deformity. The average union period was 6.3 weeks (range, 5-9weeks). Fifteen cases (79%) showed excellent results, four cases good results based on TAM. No case showed rotational deformity. Two cases had skin irritation by distal wire end, which was subsided after wire removal. CONCLUSIONS: In patients with a metacarpal shaft fracture, retrograde intramedullary fixation using two pre-bent K-wires can provide satisfactory clinical results.

Purpose: To evaluate the relationship between the clinical outcome and the cuff integrity following open repair in large and massive rotator cuff tears using ultrasonography as an imaging modality. Material and Methods: From November 2001 to April 2005, 17 cases(16 patients) who had open repair of tear measuring more than 3cm were assessed with minimal follow-up of 12 months in this study. 6 cases had a large tear and 11 cases a massive tear. There were 6 men and 11 women with a mean age of 52 years at surgery (range, 33 to 72 years). The evaluation consisted of the preoperative and postoperative shoulder scores according to UCLA shoulder scoring system and Visual analogue scale (VAS). Ultrasonography was performed by a experienced musculoskeletal physician at a minimum of 12 months postoperatively to evaluate the postoperative cuff integrity. Results: Retear were detected in four of seventeen cases. Regardless of the presence of recurrent tear, 14 cases had UCLA score of more than 29 points (good grade). All 17 had an improvement in the functional score, which increased from an average of 15.1 to 31.2 points. All cases showed pain relief and five cases had no pain. Sixteen cases except one had the range of motion of forward elevation above 90degrees. Conclusion: Open rotator cuff repair in large and massive tears showed low retear rate. At a minimum of twelve months follow-up, all cases had improvement on UCLA score, pain relief, increased range of motion of the shoulder regardless of retear. And the correlation between recurrent tear and function score was not statistically significant.
