Relationship of Patellofemoral Angles and Tibiofemoral Rotational Angles With Jumper's Knee in Professional Dancers: An MRI Analysis.

BACKGROUND: Jumper's knee is a type of tendinopathy affecting the distal insertion of the quadriceps tendon (25% of cases) or the patellar tendon. It has been shown that frontal-plane measurements, such as genu valgum, genu varum, an increased quadriceps angle, a protuberant tibial tuberosity, patella alta, and short hamstring muscles, may be related to jumper's knee. PURPOSE: To investigate the effects of tibiofemoral rotational angles and patellofemoral (PF) angles on the development of jumper's knee in professional folk dancers. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: We examined 26 dancers (16 male, 10 female) with knee pain using magnetic resonance imaging (MRI), for a total of 32 knees. Of the knees, 21 with quadriceps tendinopathy (QT) and 7 with patellar tendinopathy (PT) were detected. Using MRI scans, we measured PF angles (PF sulcus angle, lateral PF angle, patellar tilt angle, lateral trochlear inclination angle, lateral patellar tilt angle, and PF congruence angle) and tibiofemoral rotational angles (condylar twist angle, posterior condylar angle, femoral Insall angle, tibial Insall angle, posterior tibiofemoral angle, and angle between the Whiteside line and posterior femoral condylar line) and noted specifics such as patella alta, patella baja, and the Wiberg classification of the patellar shape between the patients with versus without QT and between patients with versus without PT to understand if there was any relationship with tendinopathy. RESULTS: No statistically significant difference was observed in age, sex, patella alta, or the Wiberg classification between the QT groups (with vs without) and between the PT groups (with vs without) (P > .05). Having QT was found to be significantly associated with the PF sulcus angle (P = .009), and having PT was found to be significantly associated with the femoral Insall angle (P = .029). CONCLUSION: Jumper's knee was found to be associated with anatomic variations of the PF sulcus angle and rotation of the patellar tendon in relation to the femur (femoral Insall angle) on axial MRI scans in professional dancers. Unlike those of other athletes, dancers' knees are exposed more to external rotation forces because of turnout, and this can be the cause of jumper's knee.

Traumatic knee injury patterns in Anatolian folk dancers: a case series and literature review.

Lower extremities, especially the knee region, are susceptible to traumatic injuries because of long-lasting hard landings and impacts. Most of the injuries described in the literature are associated with ballet. In this review study, the authors tried to present the traumatic knee injury patterns of the Anatolian folk dance. The Fire of Anatolia dance group consists of 82 dancers (37 males [45.1%] and 45 females [54.9%]) with the mean age of 27.96 (SD = 5.05) years (range: 18-38 years). The major folk dances of the region are Zeybek, Halay, Horon, Teke, Roman, Karsilama, Bar and Lezginka ("the Caucasian"). The dancers suffered from 9 orthopedic injuries requiring surgical treatment (3 meniscus tears, 4 anterior cruciate ligament tears, 1 posterior cruciate ligament tear, 1 patellar dislocation) during a 10-year period. The authors investigated solely the traumatic injuries of these folk dance styles and aimed at revealing the traumatic knee injury patterns in this case series and literature review. On the one hand, the Anatolian folk dancers experienced meniscus tears following frequent squats and twists on single leg stances, typical of Horon and Zeybek. On the other hand, anterior cruciate tears happened after jumps and landings in the Caucasian (Lezginka jump) dance. A posterior cruciate ligament tear was also seen after the Caucasian dance landing. The split figure in the Karsilama dance ended up with patellar dislocation. Certain dance figures seem to be related to specific types of injuries. Int J Occup Med Environ Health. 2019;32(5):585-93.

The ANK nail treatment of lateral malleolar fractures with syndesmosis injury: Clinical outcomes at 10 years of follow-up.

BACKGROUND: Lateral malleolar fractures associated with syndesmotic injuries are common. Various surgical implants may be used for the management of syndesmosis injury. One of these is ANK nail. The aim of the present study was to assess the clinical and radiological outcomes of patients treated with ANK nail. METHODS: Forty-eight patients who were followed up for a minimum of 10 years were reviewed retrospectively using American Orthopedic Foot and Ankle Society (AOFAS) score, radiological evaluation, and development of posttraumatic arthritis. Final data were collected at the last follow-up. RESULTS: The mean age of the patients was 37.3 (17-69) years. The mean follow-up was 129.9 (123-150) months. Twenty-two patients had Weber type B fracture, and their mean AOFAS score was 93.36 points. The remaining 26 patients had Weber type C fracture, and their mean AOFAS score was 97.66 points. There was no relationship between the type of fracture and the clinical outcome. There was a significant correlation between shortening of the fibula and posttraumatic arthritis. CONCLUSION: The ANK nail used for the management of ankle fractures may provide both fracture and syndesmosis stabilities in selected cases and is also a cost effective method as cheap as a cortical screw and a Kirschner wire.

Minimally invasive plate osteosynthesis (MIPO) in diaphyseal humerus and proximal humerus fractures.

OBJECTIVE: Our aim was to evaluate the results of minimally invasive plate osteosynthesis (MIPO) using locking plates in diaphyseal humerus and proximal humerus fractures. METHODS: Nine patients who underwent open reduction and MIPO for the treatment of diaphyseal and proximal humerus fractures between June 2006 and October 2009 were included in this study. One S3(®) and 8 PHILOS(®) plates were used. Mean age was 75.2 (range: 32 to 86) years and all patients were females. Mean follow-up was 33.9 (range: 14.8 to 54.8) months. According to AO/ASIF classification, four patients had 12C1, two patients 12A1, one patient 12A2, and two patients 11A2 fractures. Axillary and radial nerves were explored and protected in all patients. Patients were evaluated radiographically for union and functionally using the Constant-Murley score. RESULTS: None of the patients had nonunion, avascular necrosis, axillary or radial nerve paralysis or implant failure. Mean Constant-Murley score was 86.8 ± 2.2 (range: 70 to 100). Mean union time was 3.2 (range: 2.5 to 5) months. CONCLUSION: MIPO of humerus diaphysis and proximal fractures allows for preservation of blood supply in fracture fragments, owing to less soft tissue and periosteal injury. When the procedure is performed with the lateral double incision, exposure and preservation of the axillary and radial nerves are necessary. Early return of function in the shoulder and elbow joints and favorable healing time are the major advantages of this method in this rare subset of humerus fractures.

Simultaneous repair of chronic full-thickness rotator cuff tears during fixation of proximal humerus fractures and clinical results.

OBJECTIVES: We investigated the incidence of chronic rotator cuff tears encountered during fixation of proximal humerus fractures with locking plate-screw systems, and evaluated the functional results of simultaneous surgical repair of these injuries. METHODS: A total of 111 patients underwent surgical treatment for proximal humerus fractures. Of these, nine patients (8 females, 1 male; mean age 73 years; range 56 to 84 years) who had concomitant chronic full-thickness rotator cuff tears were included in the study. According to the AO classification, the fractures were type 11A1 (12C1 also present) in one patient, 11A2 (12C2 also present) in one patient, 11B1 in two patients, 11B2 in three patients, and 11C2 in two patients. None of the patients underwent preoperative magnetic resonance imaging. Fracture fixation was made with the PHILOS plate in five patients, and with the S3 Proximal Humerus Plate in four patients. All full-thickness rotator cuff tears were detected during the operation. Following open reduction and internal fixation after a deltoid splitting incision, rotator cuff tears were repaired by primary suture in two patients, and with a suture anchor in seven patients. All the patients used a padded shoulder-arm sling for six weeks and received a standard rehabilitation program. All the patients were evaluated radiographically and functionally using the Constant-Murley shoulder score at postoperative 6 weeks, 6 months, and 12 months. The mean follow-up period was 17.3 months (range 8 to 30 months). RESULTS: The incidence of full-thickness rotator cuff tears was 8.1%. All the patients had supraspinatus tears, which were accompanied by infraspinatus tears in three patients. The sizes of the tears were classified as large (between 3-5 cm) in three patients, intermediate (between 1-3 cm) in five patients, and small (<1 cm) in one patient. One patient had L-shaped, two patients had U-shaped, and six patients had C-shaped tears. None of the patients had healing problems or avascular necrosis. The mean Constant-Murley shoulder score was 85.4 (range 67 to 100). All the patients were satisfied with the results of surgical treatment. CONCLUSION: The integrity of the rotator cuff must be checked after reduction and fixation of proximal humerus fractures and, when present, the tears should be repaired simultaneously either primarily or with suture anchors. Simultaneous repair of rotator cuff tears does not negatively affect functional outcomes.

Complications encountered in proximal humerus fractures treated with locking plate fixation.

OBJECTIVES: We evaluated the complications encountered following locking plate fixation of proximal humerus fractures. METHODS: The study included 103 patients (70 females, 33 males; mean age 62 years; range 21 to 90 years) who were treated with open reduction and locking plate fixation for proximal humerus fractures between September 2005 and April 2009. Fixation was performed using the PHILOS locking plate in 93 patients, and S3 humerus plate in 10 patients. Postoperatively, a shoulder-arm sling was applied for six weeks and a standard rehabilitation program was used in all the patients. Intraoperative, acute postoperative, and late postoperative complications were assessed on radiographs. Varus inclination was defined as less than 120 degrees of the inclination angle on immediate postoperative radiographs, and varus displacement as postoperative increases in the varus angle. The mean follow-up period was 19 months (range 2 weeks to 43 months). RESULTS: Complications were seen in 10 patients (9.7%; mean age 67 years). The PHILOS plate was used in nine patients and S3 plate was used in one patient. Five patients (4.9%) had varus inclination with a mean inclination angle of 112.6 degrees (range 105 degrees to 118 degrees), four patients (3.9%) developed varus displacement with a mean inclination angle of 102.5 degrees (range 95 degrees to 110 degrees), and intra-articular screw penetration was seen in five patients (4.9%). The remaining complications were fixation failure (n=1, 1%), implant fracture (n=1), and deep infection (n=1). Screw penetration exceeded 3 mm in three patients, requiring revision surgery. The mean ages of patients with varus inclination, varus displacement, and screw penetration were 76.6, 74.4, and 71 years, respectively. Three patients with varus inclination (60%) developed varus displacement. Screw penetration was observed in three patients (60%) with varus inclination, and in all patients with varus displacement. The mean Constant-Murley shoulder score was 67.8 (range 50 to 90) in patients who developed a complication. CONCLUSION: Our findings show that locking plate and screw systems represent a significant treatment option in the treatment of comminuted and displaced humerus fractures, with low complication rates. Accurate indication, protection of the head's inclination angle through appropriate surgical approach and proper technique, and fine calculation of screw length are essential for successful functional results.

[Surgical treatment of elbow dislocations accompanied by coronoid fractures]. / Koronoid kiriklarinin eslik ettigi dirsek çikiklarinda cerrahi yaklasim.

OBJECTIVES: We evaluated the results of surgical treatment for elbow dislocations accompanied by Regan-Morrey type 2-3 coronoid fractures. METHODS: Eight patients (6 males, 2 females; mean age 44 years; range 23 to 76 years) underwent surgical treatment for elbow dislocations accompanied by a coronoid fracture. Three patients had Regan-Morrey type 2, five patients had type 3 coronoid fractures. Accompanying injuries were Mason-Johnston type 4 radial head fractures (n=6), olecranon fractures (n=4), lateral humeral condyle fracture (n=1), and lateral (n=5) or medial (n=2) collateral ligament ruptures. Coronoid fractures were fixed with a plate, screw, or a cerclage wire in all the patients except for one patient who underwent coronoid excision. For radial head fractures, plate or screw and K-wire fixation was performed in two patients and radial head prosthesis was used in four patients. Olecranon fractures were fixed with a plate or AO tension band. Functional results were assessed using the Mayo elbow performance score. The mean follow-up period was 22.6 months (range 1 to 65.5 months). RESULTS: Union was achieved in all the patients. At the latest assessments, the mean Mayo elbow performance score was 84.3 (range 50 to 100). All the patients expressed satisfaction with surgical treatment except for one patient who underwent coronoid excision. All the fixation materials used for olecranon fractures were removed after union due to implant-associated pain. Ulnar nerve transposition was required in two patients with fractures involving the anteromedial facet of the coronoid process. Two patients developed heterotopic ossification that did not affect the range of motion of the elbow. CONCLUSION: Surgical treatment of elbow dislocations associated with Regan-Morrey type 2-3 coronoid fractures enables a concentric reduction of the elbow, stability, and early motion.

[Early results of autologous mononuclear bone marrow cell implantation in nontraumatic avascular necrosis of the femoral head]. / Travmaya bagli olmayan femur basi osteonekrozunda otolog konsantre mononükleer kemik iligi hücre naklinin erken dönem sonuçlari.

OBJECTIVES: We evaluated early clinical and radiologic results of core decompression combined with autologous mononuclear bone marrow cell implantation for early stage nontraumatic avascular necrosis of the femoral head. METHODS: The study included nine patients (1 female, 8 males, mean age 46.5 years; range 33 to 59 years) with stage I-II nontraumatic avascular necrosis of the femoral head, according to the Steinberg classification. Bone marrow-derived CD34 cells were injected through a core decompression channel into the femoral head. Clinical assessment included a visual analog scale (VAS), Harris hip score, and the WOMAC Osteoarthritis Index. Radiologically, femoral head collapse, narrowing of the coxofemoral joint space, and the size of the osteonecrotic area were assessed. The mean follow-up was 27.2 months (range 24 to 38 months). RESULTS: Pre- and postoperative (24th month) evaluations showed that the mean VAS score and the WOMAC Osteoarthritis Index decreased from 3.4+/-0.4 to 1.2+/-0.6, and from 33+/-3 to 11+/-6, respectively, with an increase in the Harris hip score (from 54 to 92). Preoperatively, two patients were Steinberg I-B, four were I-C, and three were II-A. Finally, all the patients were stage 0 except for one patient who regressed to I-A. None of the patients exhibited femoral head collapse or narrowing of the coxofemoral joint space. CONCLUSION: Autologous mononuclear bone marrow cell implantation relieves articular pain, prevents the progression of osteonecrosis, and hence subchondral fractures. Therefore, it may be treatment of choice particularly in stage I-II avascular necrosis of the femoral head.

[The results of internal fixation of proximal humeral fractures with the PHILOS locking plate]. / Proksimal humerus kiriklarinda kilitli plak PHILOS ile internal tespit sonuçlari.

OBJECTIVES: Proximal and diaphyseal humeral fractures are common especially in the elderly, presenting as a challenging problem due to their high complication rates following surgical treatment. In this prospective study, we evaluated the results of patients treated with the PHILOS (Proximal Humeral Internal Locking System) locking plate, a new technique recently developed by the AO/ASIF. METHODS: Forty-one patients who were treated with the PHILOS plate for proximal humeral fractures were evaluated in two age groups. Group A included 24 patients (12 males, 12 females; mean age 47 years; range 24 to 64 years) younger than 65 years, and group B involved 17 patients (4 males, 13 females; mean age 78 years; range 67 to 90 years) at or above 65 years. Radiographically, all fractures were classified according to the AO/ASIF system. Surgery was performed with the deltopectoral approach in 10 and two patients, and with a deltoid split in 14 and 15 patients in group A and B, respectively. Functional and radiographic results were evaluated after a mean follow-up of 15 months (range 6 to 28 months). RESULTS: The mean Constant scores were 95.0 (range 74 to 100) and 92.8 (range 72 to 100) in group A and B, respectively (p>0.05). After six months of surgery, Constant scores and functional outcomes were similar in patients operated on with the deltopectoral approach or deltoid split. There was neither nonunion nor implant failure. Complications included intra-articular screw penetration (n=1), displacement of the greater tuberculum (n=1) with oblique placement of the plate (n=1), insufficient reduction (n=4), and varus displacement of the humeral head (n=3). No avascular necrosis was seen. CONCLUSION: Locking plate system is superior over other means of fixation methods, particularly in osteoporotic fractures, because it allows early rehabilitation and does not result in implant failure.

[Occult scapholunate ganglion in patients with dorsoradial wrist pain]. / Dorsoradial el bilegi agrisi olan olgularda gizli skafolunat gangliyon.

OBJECTIVES: The aim of this study was to assess the results of surgical treatment of patients who had complaints of chronic wrist pain and were diagnosed as having an occult dorsal scapholunate interosseous ganglion, despite the presence of a normal x-ray and absence of trauma. METHODS: Thirteen wrists of 12 patients (2 males, 10 females; mean age 28 years; range 21 to 41 years) were treated with surgical excision for ganglia originating from the dorsal scapholunate interosseous ligament. Involvement was on the right side in six patients, and on the left in five patients, with one patient having bilateral involvement. None of the patients had a history of trauma, except two with a history of fall. All the patients had complaints of wrist pain that occurred during work and subsided at rest. The mean duration of wrist pain was 23 months (range 6 to 60 months). All the patients received conservative treatment previously with wrist splints and non-steroidal anti-inflammatory drugs. Finger extension test was positive and magnetic resonance imaging of the wrist showed ganglion in all the patients. Functional results were evaluated by the Mayo Clinic wrist pain assessment scores after a mean follow-up of 35 months (range 25 to 49 months). RESULTS: Complaints of wrist pain improved dramatically in all the patients. Scores of the Mayo Clinic wrist pain assessment were excellent in seven patients (53.9%), good in five patients (38.5%), and moderate in one patient (7.7%). All the patients returned to work without any limitation of wrist movements. No recurrences were seen during the follow-up period. CONCLUSION: Occult ganglia originating from the scapholunate ligament should be remembered in patients with dorsal scapholunate joint tenderness and pain unresponsive to conservative treatment and with a positive finger extension test.

[Quadriceps tendon ruptures: evaluation and treatment]. / Kuadriseps tendonu kopmalarinda degerlendirme ve tedavi.

OBJECTIVES: We evaluated the patients who underwent surgical repair for rupture of the quadriceps tendon. METHODS: Five patients (4 men, 1 woman; mean age 56 years; range 33 to 77 years) had rupture of the quadriceps tendon at the osteotendinous junction. One patient had bilateral rupture. Etiology was a traffic accident in one patient, and fall from height in two patients. Two patients who were on dialysis treatment developed simultaneous bilateral rupture. Ruptures were repaired with heavy, nonabsorbable sutures placed in transosseous tunnels in the patella. The mean follow-up was two years (range 1 to 5 years). RESULTS: Complete healing was seen in all the patients within six months. The mean range of motion was 0 to 119 degrees. Muscle atrophy was not detected. Muscle strength was equal on both sides. None of the patients complained of patellofemoral pain. CONCLUSION: Ruptures of the quadriceps tendon can be successfully managed through early diagnosis and surgical treatment. It should be recalled that concomitant diseases may predispose to ruptures in cases above 40 years of age.

[Rupture of the triceps brachii tendon: a case report]. / Triceps brachii tendon kopmasi: Olgu sunumu.

Triceps tendon rupture is a rare condition. A thirty-three year old man presented with a complaint of pain in his left elbow, which occurred when his motorcycle slid and flipped on one side. Physical examination two days after the accident showed swelling and ecchymosis in the elbow. There was a palpable, slightly tender defect in the triceps tendon just above the olecranon. He had normal supination and pronation. A marked weakness was noted in elbow extension as compared with the other side. A diagnosis of triceps tendon rupture was made. Radiographs revealed osteoarthrosis of the elbow joint and osteophyte formation on the top of the olecranon. Magnetic resonance scans showed a partial tear in the triceps tendon. It was repaired with large, nonabsorbable sutures passed through the holes drilled in the olecranon. The extremity was immobilized for three weeks, followed by progressive active flexion in a controlled-motion brace. Active strengthening of the triceps was begun after three months. At the end of a year, the range of motion of the elbow was full except 10 degrees loss of extension and there was no pain.

[The correlation between the accuracy of steroid injections and subsequent shoulder pain and function in subacromial impingement syndrome]. / Subakromiyal sikisma sendromunda steroid enjeksiyonunun dogru sekilde uygulanmasi ile omuz agrisi ve fonksiyonu arasindaki iliski.

OBJECTIVES: We assessed the relationship between proper placement of corticosteroid injections and subsequent shoulder function and pain in subacromial impingement syndrome. METHODS: The study included 48 patients (29 women, 19 men; mean age 46.5 years; range 23 to 58 years) with subacromial impingement syndrome, whose complaints of shoulder pain lasted more than two months. To monitor the site of injection, contrast material was added to a mixture of steroid and local anesthetic solution. Injections were delivered into the subacromial bursa by an anterolateral approach. Radiographs of the joint were taken immediately afterwards to ensure the accurate placement of the injection. Shoulder function and pain were evaluated by visual pain scale, range of movement of the joint, and Constant scores before treatment, and half an hour and two weeks after the injections. RESULTS: The injections were placed accurately in 42 patients (87%), while in six patients (12.5%), delivery to the target site failed. Statistically significant improvements were observed in both groups half an hour after the injections (p<0.05). However, two weeks after the treatment evaluations showed that failure to obtain an accurate placement was associated with return to pretreatment values, while significant improvement continued in the other group. CONCLUSION: Failure to deliver injections to the target site may be decreased by increased utilization of visualization and imaging methods.
