How to Avoid Graft-Tunnel Length Mismatch in Modified Transtibial Technique for Anterior Cruciate Ligament Reconstruction Using Bone-Patellar Tendon-Bone Graft

BACKGROUND: We conducted this study to determine the optimal length of patellar and tibial bone blocks for the modified transtibial (TT) technique in anterior cruciate ligament (ACL) reconstruction using the bone-patellar tendon-bone (BPTB) graft. METHODS: The current single-center, retrospective study was conducted in a total of 64 patients with an ACL tear who underwent surgery at our medical institution between March 2015 and February 2016. After harvesting the BPTB graft, we measured its length and that of the patellar tendon, patellar bone block, and tibial bone block using the arthroscopic ruler and double-checked measurements using a length gauge. Outcome measures included the length of tibial and femoral tunnels, inter-tunnel distance, length of the BPTB graft, patellar tendon, patellar bone block, and tibial bone block and graft-tunnel length mismatch. The total length of tunnels was defined as the sum of the length of the tibial tunnel, inter-tunnel distance and length of the femoral tunnel. Furthermore, the optimal length of the bone block was calculated as (the total length of tunnels − the length of the patellar tendon) / 2. We analyzed correlations of outcome measures with the height and body mass index of the patients. RESULTS: There were 44 males (68.7%) and 20 females (31.3%) with a mean age of 31.8 years (range, 17 to 65 years). ACL reconstruction was performed on the left knee in 34 patients (53%) and on the right knee in 30 patients (47%). The optimal length of bone block was 21.7 mm (range, 19.5 to 23.5 mm). When the length of femoral tunnel was assumed as 25 mm and 30 mm, the optimal length of bone block was calculated as 19.6 mm (range, 17 to 21.5 mm) and 22.1 mm (range, 19.5 to 24 mm), respectively. On linear regression analysis, patients' height had a significant correlation with the length of tibial tunnel (p = 0.003), inter-tunnel distance (p = 0.014), and length of patellar tendon (p < 0.001). CONCLUSIONS: Our results indicate that it would be mandatory to determine the optimal length of tibial tunnel in the modified TT technique for ACL reconstruction using the BPTB graft. Further large-scale, multi-center studies are warranted to establish our results.

Clinical Results of the Arthroscopic “Multiple Pulled Suture” Technique for Large or Comminuted Bony Bankart Lesion

BACKGROUND: Arthroscopic fixations for large and comminuted bony Bankart lesions are technically difficult. We developed an arthroscopic multiple pulled suture (MPS) technique to restore large and comminuted bony Bankart lesions. METHODS: Ten patients (mean age, 49.8 years; range, 31–79 years) underwent bony Bankart repair using the illustrated MPS technique and were then followed for a mean of 27.3 months. A plain radiograph series and three-dimensional computed tomography scans were taken at the initial clinical evaluation and 3 months postoperatively. Outcome measurements included the American Shoulder and Elbow Surgeons (ASES) score, Rowe score, University of California at Los Angeles (UCLA) score, and subjective patient satisfaction, along with surgical complications. RESULTS: Union of an osseous fragment with the glenoid rim was confirmed in all patients on a computed tomography scan 3 months after operation. The osseous fragment was restored to proper articular congruence and reduction. The affected shoulder was stable in nine of the 10 patients. One patient presented with a redislocation after a sports injury 3 years postoperatively. The ASES, Rowe, and UCLA scores improved at the final evaluation, and median patient satisfaction at the final follow-up was 9 of 10 points (range, 6–10 points). CONCLUSIONS: The arthroscopic MPS technique for bony Bankart lesions with large or comminuted osseous fragments was a relatively easy and safe method for stable fixation of the osseous fragment. Therefore, the arthroscopic MPS technique resulted in good restoration of stability with high patient satisfaction and low complication rates.

Comparison of the Result of the Intramedullary Nail Fixation and Plate Fixation in Humeral Shaft Fracture with Butterfly Fragments / 대한스포츠의학회지

First aim of this study was to compare the results of the intramedullary nail fixation and plate fixation for the management of humeral shaft fracture with butterfly fragments. Second aim of this study was to appraise the necessity of anatomical reduction and fixation for butterfly fragment in humeral shaft fracture. Thirty-one patients with comminuted humeral shaft fracture were treated by reduction and internal fixation with intramedullary nail or plate. The criteria for inclusion were AO classification type B, follow-up period more than 12 months, diaphyseal fracture without involvement of joints. Eighteen patients underwent intramedullary nail fixation and 13 by plate fixation. The outcome was assessed in terms of the union rate, union time, incidence of complications, and functional outcome of shoulder joint. The union rate was 94.4% in intramedullary nail group and 100% in plate group. The average union time was found to be no significant difference between two groups (p>0.05). There was no significant difference in the American Shoulder and Elbow Surgeons' score and range of motion of shoulder and elbow joint between the two groups in last follow-up (p>0.05). The union rate and average union time and functional outcome of shoulder joint was no significant difference between the intramedullary nail fixation and plate fixation for the management of humeral shaft fracture with butterfly fragments. It is recommended to select skillful technique to avoid technical errors rather than technique to fix of butterfly fragments.

Risk Factor of Depression after Amputation In Treatment of the Lower Extremity Open Fracture Associated with Severe Soft Tissue Injury / 대한정형외과연구학회지

PURPOSE: To evaluate the incidence rate and risk factors for depression after amputation in treatment of the lower extremity open fracture associated with severe soft tissue injury. MATERIALS AND METHODS: We carried out a retrospective case-control study of 30 patients, who underwent lower extremity amputation between March 2002 and February 2012 and subsequently followed up over 12 months. We classified the patients into two groups: group A (study group, depression expressed) and group B(control group, normal). The risk factors were then subdivided based on patient-related factors such as whether or not patients received psychiatric treatment, sociolopsychological environmental factors, and daily activities after recovery. RESULTS: The overall incidence rate of depression was 40%;20 patients were male, and 10 patients were female (66.7% and 33.3%, respectively). Age (odd ratio=1.14), Accompanying injury (odd ratio=2.06), underlying disease, Psychiatric treatment (odd ratio=44.73), sociopsychological environment (odd ratio=17.53),daily activities (odd ratio=8.76) were significant. CONCLUSION: We concluded that the risk factors for depression after amputation are age, accompanying injury, and underlying diseases, irrespective of whether or not patients received psychiatric treatment, and not associated with isolated sociopsychological environments, or hypoactivity of daily living.

Coagulase-Positive Staphylococcal Necrotizing Fasciitis Subsequent to Shoulder Sprain in a Healthy Woman

Necrotizing fasciitis (NF) is a deep infection of the subcutaneous tissue that progressively destroys fascia and fat; it is associated with systemic toxicity, a fulminant course, and high mortality. NF most frequently develops from trauma that compromises skin integrity, and is more common in patients with predisposing medical conditions such as diabetes mellitus, atherosclerosis, alcoholism, renal disease, liver disease, immunosuppression, malignancy, or corticosteroid use. Most often, NF is caused by polymicrobial pathogens including aerobic and anaerobic bacteria. NF caused by Staphylococcus aureus as a single pathogen, however, is rare. Here we report a case of NF that developed in a healthy woman after an isolated shoulder sprain that occurred without breaking a skin barrier, and was caused by Staphylococcus aureus as a single pathogen.

Assessment of the Clinical Features of Bilateral Sequential Hip Fractures in the Elderly / 대한정형외과학회잡지

PURPOSE: We wanted to evaluate the clinical features after treating of bilateral sequential hip fractures in the elderly. MATERIALS AND METHODS: We reviewed the clinical records of 21 patients who were older than 75 years and who underwent bilateral bipolar hemiarthroplasty for sequential hip fractures between March 1999 and November 2005. The minimum follow up period was 2 years. We analyzed the results by conducting radiological and clinical evaluations such as assessing the patient's walking ability, the activities of daily living, the mechanism of fracture and the associated medical conditions and arthritis. RESULTS: Walking ability was recovered by 18 cases of primary fracture and by 14 cases of sequential fracture. Return to the activities of daily living was achieved by 14 cases of primary fracture and by 14 cases of sequential fracture. The fracture mechanism was a fall/slip in 20 cases and a fall from a height in 1 case. The associated arthritis was in the spine in 14 cases, the knee in 11 cases, the shoulder in 8 cases and Hallux valgus in 5 cases, and the associated medical conditions were mainly urge incontinence in 17 cases and cardiovascular disease in 16 cases. The other previous fractures were spine compression fracture in 11 cases, ankle fracture in 6 cases, distal radius fracture in 5 cases and pelvic ramus fracture in 2 cases. CONCLUSION: Preventing recurrent falls plays a role in preventing bilateral sequential hip fractures. We think that the treatment of curable associated medical conditions and arthritis is necessary to prevent recurrent falls.

Operative Treatment for Ulnar Styloid Process Fractures with Unstable Intraarticular Distal Radius Fractures

PURPOSE: To evaluate the radiological and clinical outcomes of the operative treatment for the unstable distal radius fractures with displaced ulnar styloid process fractures. MATERIALS AND METHODS: From 2002 to 2005, 17 patients with unstable distal radius fractures with displaced ulnar styloid process fractures were treated operatively, using external fixation or internal fixation for distal radius and open reduction with tension band wiring for ulnar styloid process fractures. We evaluated postoperative outcomes with Mayo wrist score, range of motion, ulnar side wrist pain, wrist stress test, grip strength as well as radiological evaluation. RESULTS: All ulnar styloid process fractures were completely united, and according to Mayo wrist score, 7 cases(41%) were excellent, 8 cases(47%) were good. 14 cases(82%) had no ulnar wrist pain and 15 cases(88%) had grip strength more than 50% when compared with the normal side. Posterior instability of ulnar head occurred at 1 case. CONCLUSION: We got acceptable clinical and radiological results of operative treatment of ulnar styloid process fractures and concluded that ulnar styloid process fractures combined with distal radius fractures should be carefully evaluated and treated operatively according to their fracture types.

Bipolar Hemiarthroplasty for Femoral Neck Fractures in the Elderly

PURPOSE: To evaluate outcomes after treatment of femoral neck fractures in patients 75 years of age or older. MATERIALS AND METHODS: We reviewed the records of 186 patients 75 years of age or older who underwent bipolar hemiarthroplasty between March 1995 and March 2005 and who were followed for more than two years after surgery. The mean patient age was 84.3 years (range 75~99 years). Forty-eight patients were men, and 138 patients were women. The mean follow-up period was 68.4 months (range 24~113 months). We evaluated the results by analyzing modified Harris hip score, walking ability, activities of daily living, complications, osteoporosis, and radiologic findings. RESULTS: The mean Harris hip score was 89.2 (range 74~95). Walking ability was recovered in 87.6% of cases (163 cases), and activities of daily living were achieved in 85.4% of cases (159 cases). There were 3 cases of acetabular erosion or proximal migration and 3 cases of aseptic loosening in a cemented stem. Thigh pain occurred in 8 cemented stems and in 4 cementless stems. CONCLUSION: We believe bipolar hemiarthroplasty is a useful treatment in elderly patients with femoral neck fractures and severe osteoporosis, especially in view of the stable and rigid fixation of the femoral stem, early ambulation, and the low rate of complications and death, even if the operation is technically very difficult.

Risk Factors Predicting Hip Fractures in Patients Over 70 Years Old

PURPOSE: We conducted a retrospective case-control study to evaluate the factors predictive of hip fractures in elderly patients. MATERIALS AND METHODS: We studied 172 patients age 70 years or older who sustained hip fractures with minor injuries between January 2002 and January 2007. We analyzed bone mineral density, comorbidities, body mass index, and the activities of daily living (ADL) scale. One hundred eighty patients (control subjects) with no history of fracture were matched to the study subjects with respect to age and sex. RESULTS: Multivariate logistic regression showed that female sex, low bone mineral density, high ADL scale, cerebral vascular attack, and knee osteoarthritis were associated with an increased incidence of hip fracture. CONCLUSION: Female sex, low bone mineral density, and high ADL scale were related to hip fractures in the elderly. Knee osteoarthritis should be regarded as an independent risk factor for fractures because of an increased risk of falling.

Bipolar Hemiarthroplasty Using Calcar Replacement Stem for Hip Fractures in the Elderly

PURPOSE: To evaluate the results of bipolar hemiarthroplasty using calcar replacement stem for hip fractures in elderly patients. MATERIALS AND METHODS: Between March 1995 and March 2005, the clinical records on 68 cases more than 75 years old who underwent the bipolar hemiarthroplasty using calcar replacement stem and followed minimum 2 years were reviewed. We evaluated the results by modified Harris hip score, walking ability, activity of daily living, complications, osteoporosis and radiologic findings. RESULTS: The mean postoperative modified Harris hip score was 88.3 (69~95) in femoral neck fractures and 83.5 (63~91) in femoral intertrochanteric fractures. Walking ability was recovered in 82.3% (56 cases) and activity of daily living was achived in 82.3% (56 cases). Complications were thigh pain, infection, femoral stem subsidence, stress shield, dislocation. CONCLUSION: We consider bipolar hemiarthroplasty using calcar replacement stem for unstable hip fractures in elderly patients with severe osteoporosis is the useful treatment in view of the stable and rigid fixation, early ambulation and the low rate of complications, even if the operation is technically very difficult.
