The Cause of Primary Reduction Failure in Hip Dislocation with or without Hip Fracture

PURPOSE: A rapid and accurate reduction is important for hip dislocated patients to avoid various potential complications, including avascular necrosis of the femoral head. We analyzed hip dislocation cases, ones that particularly failed during the primary reduction trial. MATERIALS AND METHODS: Eighty-seven patients with hip dislocation, who visited the emergency department between January 2007 and September 2015, were retrospectively analyzed. Of them, 68 patients were successfully treated in the first closed reduction trial, and the remaining 19 patients were unsuccessful. Of the 19 unsuccessful first trial, 12 patients were successfully treated in the second closed reduction; however, in the remaining 7 patients, open reduction was performed in the operation room with general anesthesia. Every closed reduction was practiced by at least 2 orthopedic doctors, and open reduction was performed by a single senior author. RESULTS: The rate of first reduction failure was higher, with statistical significance, in patients aged under 50 years, male gender, and those with combined around hip fractures, including femoral head and acetabular fracture (p0.05). CONCLUSION: To evaluate the patients with hip dislocation, realizing the type of dislocation, presence of accompanied fracture, location and size of fracture fragment, age, as well as gender of patients is important. If the fracture fragment is impacted in the hip joint and the size of the fragment is large, then the operative treatment is considered, rather than the repetitive trial of closed reduction by constraint.

Correlation between Results of Preoperative Impingement Test and Clinical Outcomes after Arthroscopic Rotator Cuff Repair

BACKGROUND: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. METHODS: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%–75%, Group C: 25%–50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. RESULTS: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). CONCLUSIONS: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

The Role of Arthroscopy of Acute and Chronic Painful Thumb Metacarpophalangeal Joint

PURPOSE: There has been few published on arthroscopy of metacarpophalangeal joint (MCPJ) despite increasingly being used worldwide. The purpose of this study was to investigate the effectiveness of arthroscopy for pathologies around MCPJ of the thumb. METHODS: Between September 2007 and June 2015, 56 patients (56 thumb) who underwent arthroscopy of the MCPJ were retrospectively studied. Preoperative diagnoses, which were made through physical examination, plain radiograph, stress radiography, ultrasound, and magnetic resonance images (MRI), were compared with arthroscopic findings. Therapeutic arthroscopic surgeries were performed according to the needs of each patient. Functional outcomes were assessed with physical examination as well as disabilities of the arm, shoulder and hand (DASH) score and Michigan Hand outcomes Questionnaire (MHQ) score at an average 7.3 months follow-up. RESULTS: Six patients who suspected with collateral ligament injuries in MRI confirmed different diagnoses under arthroscopy. At final follow-up, the mean range of flexion contracture of the MCPJ was 5°, and the mean range of further flexion was 52.7°. Grip and pinch strength averaged 87.2% and 79.3% of contralateral side. Mean DASH and MHQ score were improved from 48.1 and 44.6, preoperatively to 14.9 and 26.3, postoperatively (p<0.001, p=0.012, respectively). All patients were satisfied with their outcomes at final follow-up, except 4 patients who noted joint stiffness or chronic pain around the thumb. CONCLUSION: Our results revealed that arthroscopy is helpful for both diagnostic and therapeutic purposes of acute and chronic painful MCPJ of the thumb. However, further studies are needed to expand the applications of arthroscopy of MCPJ of the thumb.

Deep Vein Thrombosis after Achilles Tendon Repair: A Case Report / 대한족부족관절학회지

Achilles tendon rupture is thought to be increasing with participation in sports activities. Both operative and non-operative treatments of Achilles tendon rupture include a period of immobilization. Complications following treatment of the Achilles tendon rupture include recurrence of rupture, flexor weakness, infection, and wound problems. However, deep vein thrombosis (DVT) after operative treatment of the Achilles tendon has not been reported. We report on a case of DVT after Achilles tendon repair.

Efficacy and Safety of Combined Subacromial and Intravenous Patient-controlled Analgesia after Arthroscopic Rotator Cuff Repair

BACKGROUND: This study investigated the efficacy and safety of combined subacromial and intravenous patient-controlled analgesia for control of postoperative pain after arthroscopic rotator cuff repair. METHODS: Between May 2012 and August 2014, 60 patients who underwent arthroscopic rotator cuff repair with acromioplasty and received patient-controlled analgesia were studied prospectively. Cases were divided into 2 groups: combined subacromial and intravenous infusion group (group A, 30 cases) and solitary intravenous infusion group (group B, 30 cases). The visual analogue scale was used to record the patient's level of pain every 12 hours during postoperative 72 hours and the following 48 hours after the suspension of patient-controlled analgesia. RESULTS: The mean preoperative visual analogue scale score was 7.8 in group A and 7.6 in group B, and the immediate postoperative visual analogue scale score was 7.9 and 8.1 for each group. At postoperative time (From 12 hours to 72 hours after operation), the scores of combined subacromial and intravenous infusion were significantly lower than those of solitary intravenous infusion. Significant difference in the frequency of supplemental analgesic injections was observed between group A and group B (p=0.008). However, no significant difference in complication rate was observed between the two groups (p=0.562). CONCLUSIONS: Combined subacromial and intravenous patient-controlled analgesia after arthroscopic rotator cuff repair is more effective than solitary intravenous infusion without significantly increasing complications. Therefore, combined subacromial and intravenous patient-controlled analgesia could be a effective pain control method.

Open Wedge High Tibial Osteotomy and Combined Arthroscopic Surgery in Severe Medial Osteoarthritis and Varus Malalignment: Minimum 5-Year Results

PURPOSE: To evaluate the radiologic and functional outcomes of medial open wedge high tibial osteotomy (HTO) combined with arthroscopic procedure in patients with medial osteoarthritis. MATERIALS AND METHODS: From June 1996 to March 2010, 26 patients (32 knees) who underwent medial open wedge osteotomy and arthroscopic operation for medial osteoarthritis were retrospectively reviewed. Measurements included hip-knee-ankle (HKA) angle, femorotibial angle, medial proximal tibial angle, posterior tibial slope angle, and Kellgren-Lawrence grade. Clinical evaluation was performed using Lysholm knee scoring scale and knee and function score of the American Knee Society. RESULTS: Differences between the mean preoperative and postoperative measurements were significant in all angles including the HKA angle (−5.7° and +5.5°), femorotibial angle (−1.9° and +9.8°), and medial proximal tibial angle (82.9° and 90.5°) (p<0.05). Mean Lysholm knee scoring scale was 63.6 preoperatively and 88.7 at the last follow-up, mean Knee Society knee score was 61.2 and 86.6, and mean function score was 59.3 and 87.2, respectively. All differences were significant (p<0.05). CONCLUSIONS: Medial open wedge HTO in combination with arthroscopic procedure is an effective treatment method for medial osteoarthritis to treat varus deformity and an intra-articular lesion.

Patient Satisfaction after Arthroscopic Repair of Acetabular Labral Tears

BACKGROUND: Acetabular labral tear is a main cause of hip pain and disability, often requiring surgical treatment. Improvements of hip arthroscopic technique have produced positive outcomes after labral repair with arthroscopy. The purpose of this study was to determine clinical outcomes and patient satisfaction after arthroscopic repair of acetabular labral tear. METHODS: We interviewed 21 patients (10 men and 11 women; mean age, 36 years [range, 22 to 57 years]) with acetabular labral tears that had been repaired arthroscopically in terms of satisfaction of the procedure. In addition, clinical outcome was assessed using visual analog scale (VAS) score, University of California, Los Angeles (UCLA) activity, Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, and Harris hip score, and radiologic outcome was assessed using serial radiography. The patients were followed for 24-50 months. RESULTS: The mean Harris hip score was 73 points (range, 64 to 84 points) preoperatively and 83 points (range, 66 to 95 points) postoperatively. Fifteen hips (71%) were rated excellent and good. The mean WOMAC osteoarthritis index and VAS scores were improved at final follow-up. UCLA activity at the latest follow-up improved in 16 patients. The Tonnis grade of osteoarthritis at the latest follow-up did not change in all patients. Eighteen of the patients (86%) were satisfied with the procedure. CONCLUSIONS: High rate of satisfaction after arthroscopic repair of acetabular labral tears is an encouraging outcome. Arthroscopic treatment of labral tears might be a useful technique in patients with hip pathologies, such as femoroacetabular impingement with labral tears.
