Conservative treatment alone may not give satisfactory results for medial collateral ligament injuries, so surgical treatment may be needed.In this case, the distal end of the medial collateral ligament was treated surgically because the distal end of the medial collateral ligament was caught between the sartorial fascia rupture. Through physical examination and magnetic resonance imaging, avulsion damage at the distal attachment part of the medial collateral ligament was confirmed, and the method of anchoring the distal end of the ligament to the crural fascia helped the ligament to heal with minimal tissue damage. Subsequently, satisfactory results are obtained and reported.

The infrapatellar fat pad (IPFP) is one of three fat pads located about the anterior knee. Injury in this region is relatively common. Damage to the IPFP is caused mostly by an iatrogenic injury from a surgical procedure or repeated small collision trauma. The authors experienced a case of an IPFP injury, that has not been reported in the domestic or international literature. In this case, acute IPFP separation followed by a contusion at the anterior aspect of knee in the kneeling position, confirmed using magnetic resonance imaging. The patient was fully recovered with conservative treatment.

OBJECTIVES: To report analytic results about association factors related to effect of conservative treatment in surgically indicated single level lumbar spinal stenosis patient.SUMMARY OF LITERATURE REVIEW: There have been various reports about clinical outcomes and relative factors after surgical treatment of spinal stenosis. However, there are few reports about factors related to effect of conservative treatment in surgically indicated lumbar spinal stenosis patient. MATERIALS AND METHODS: We based on 40 patients who had visited our hospital from May 2010 to April 2016 who were traceable for at least three years. We analysed 20 patients who improved symptom and who didn't improved symptom then investigated association factors related to effect of conservative treatment. Clinical assessment was conducted using questionnaire and spinal canal's area and muscle amount were measured in the MRI. RESULTS: Average of the spinal canal of not-improved group is 91.29(±34.26) mm², improved group is 130.70 (±32.18) mm² and impoved group is wider (p=0.001). Muscle mass of improved group is 91.47(±9.43) cm², not-improved group is 79.26 (±14.35) cm², and improved group is wider (p=0.003). Repetitive strain and traffic accident were related in not-improved group (p=0.028). However, practiced stretching continuously were related to symptom improvement (p=0.022). CONCLUSIONS Association factors related to effect of conservative treatment are cases of wide spinal canal, wide muscle amount, repetitive sprain, traffic accident and stretching. A small muscle amount can be considered as a key factor related to surgical conversion.

Avascular necrosis (AVN) is defined as the cellular death of bone and bone marrow components due to the loss of blood supply, and associated with post-traumatic or non-traumatic events. AVN usually involves the epiphysis of a long bone, such as the femoral and humeral heads, which are susceptible to osteonecrosis. Many studies have been conducted but they were restricted to investigations of femoral head avascular necrosis. The presence of osteonecrosis in the proximal femur may impair biological fixation after total hip arthroplasty. We report a 56-year-old male patient with avascular necrosis located not only at the femoral head, but also in the entire femur, including the medullary cavity, who underwent total hip arthroplasty 2 years earlier along with a review of the relevant literature.

OBJECTIVES: To determine the factors associated with conversion from conservative to surgical treatment in single-level lumbar spinal stenosis patients.SUMMARY OF LITERATURE REVIEW: Various reports have presented clinical outcomes after the surgical and nonsurgical treatment of spinal stenosis. However, few reports have investigated factors predicting conversion to surgery during the course of conservative treatment. MATERIALS AND METHODS: We analyzed 40 patients who visited our hospital from May 2010 to May 2015 and were traceable for at least 3 years after being advised to undergo surgery following 3 months of conservative treatment. Of these patients, 20 underwent surgery and 20 did not. We then investigated the factors associated with conversion to surgical treatment. Clinical assessments were conducted using a questionnaire, and the overall area of the spinal canal and the muscle area within the spinal canal were measured using magnetic resonance imaging. RESULTS: The average area of the spinal canal was 81.40±53.61 mm2 in the surgical group, compared to 127.75±82.55 mm2 in the nonsurgical group (p=0.042). The muscle area in the spinal canal was 5.17±1.30 cm2 in the surgical group, whereas it was 6.40±1.56 cm2 in the nonsurgical group (p=0.010). The patients in the surgical group were more likely to have experienced repetitive strain and to have frequently visited health clubs (p=0.047, p=0.037, respectively). However, regular stretching was more common in the nonsurgical group (p=0.028). CONCLUSIONS The factors associated with conversion to surgical treatment were a narrow spinal canal, a small muscle area within the spinal canal, visiting health clubs, repetitive sprain, and not stretching. A small muscle area within the spinal canal can be considered as a key factor related to surgical conversion.

STUDY DESIGN: Prospective study. OBJECTIVES: To assess the correlation between symptom improvement and spinal canal dimensions in patients who underwent selective nerve root block for lumbar spinal stenosis. SUMMARY OF LITERATURE REVIEW: When the canal size is relatively small, the pressure on the nerve root increases. Decompressive surgery relieves more pain in such patients. MATERIALS AND METHODS: From July 2009 to March 2011, 141 patients received selective nerve root block for 1-level central lumbar spinal stenosis in our hospital. We evaluated the patients using a visual analog scale (VAS) before the procedure and 1 hour, 1 month, and 3 months following the procedure. We measured the spinal canal using magnetic resonance imaging. RESULTS: There was no significant correlation between spinal canal dimensions and the pre-procedure VAS. We divided the patients into 3 groups using the average and the standard deviation of the patients' spinal canal dimensions (<73.1 mm², 73.1-172.5 mm², >172.5 mm²) (p<0.01). One hour after the procedure, the VAS scores changed by 1.43±1.8, 1.62±1.7, and 1.53±1.5, respectively, with no significant differences among the 3 groups. However there were significant differences in the VAS changes 1 month and 3 months following the procedure, with results of 2.39±1.7 and 1.39±1.5, 4.65±2.1 and 4.28±2.3, and 4.97±2.2 and 6.83±1.9 (p<0.01), respectively. CONCLUSIONS: The smaller the area of the spinal canal, the less likely symptoms were to improve after selective nerve root block. The results of this study will help predict the effects of selective nerve root block in spinal stenosis patients.

PURPOSE: Anatomical medial knee reconstruction is crucial to the recovery of the knee joint. Our purpose is to determine the location of femoral insertion of the superficial medial collateral ligament (sMCL) and posterior oblique ligament (POL) from the attachment site of the adductor magnus and medial gastrocnemius tendon with MRI results. MATERIALS AND METHODS: A total of 200 knee magnetic resonance imaging results were retrospectively measured. The boundary of femoral insertion of sMCL and POL was marked and measured on the sagittal image. The attachment site of the adductor magnus tendon and medial gastrocnemius tendon was identified. The lineal, anterior-posterior and proximal-distal distances were measured from the attachment site to the center of the femoral insertion of sMCL and POL. RESULTS: The average size of sMCL and POL was as follows—sMCL: length of 13.5±1.7 mm, width of 10.9±0.3 mm and POL: length of 9.4±1.3 mm, width of 6.1±0.5 mm. The lineal distances from the insertion of the adductor magnus tendon and medial gastrocnemius tendon to the center of the sMCL and POL were measured—distances to the sMCL: 17.1±3.8 mm, 15.9±3.2 mm; distances to the POL: 11.9±2.9 mm, 8.2±2.7 mm. CONCLUSION: This study will help determine the location of the femoral attachment site of sMCL and POL by identifying the attachment section of the adductor magnus tendon and medial gastrocnemius tendon. Moreover, this study will guide the reconstruction of sMCL and POL when palpation of the bony structures become difficult.

Humeral shaft fracture sustaining arm wrestling is rare, but occurs intermittently. We treated 15 cases of humeral shaft spiral fractures occurred during arm wrestling for fun since 2007. Average age was 22.47±2.69 years, average body mass index was 22.67±2.06 kg/m2. There was no prominent tendency for the fractures to occur at a certain phase of the match. Fractured level and length of each case were measured in the plain radiographs and compared with those of previous reports. Eight cases (53.3%) had an associating medial butterfly fragment, and the time taken until the fracture occurred was longer than that of simple spiral fracture (15.62±9.03 seconds vs. 7.85±2.67 seconds, p=0.048). Fractures were distributed mid to distal one third of humerus, the length of fracture was 7.93±2.69 cm and involved 25.43%±8.24% of humeral length. All cases except one treated surgically using plate and screws and returned their full activities within postoperative 3 months. Although arm wrestling is a simple and joyful sport, participants should be aware of the risks of injury during arm wrestling, especially for the amateur players.
