Coloarticular fistula following hip arthroplasty: A report of two cases.

Coloarticular fistulas extending to the hip joint are rare and serious pathologies causing morbidity and mortality due to sepsis. Herein, we present two cases with rarely seen coloarticular fistula complications following hip arthroplasty operations. One is with extracting gas from the cutaneous fistula after multiple revision total hip arthroplasty operations and one is after bipolar hip hemiarthroplasty with radiation therapy as a possible etiological factor. These reports emphasize that the drains must be followed for a possible color change and air uptake due to intestinal gas content after infected hip arthroplasty operations.

Traction therapy in lumbar disc hernias: A finite element analysis study.

OBJECTIVES: This study aims to evaluate the results of lumbar traction treatment at different traction angles and different traction forces using the finite element analysis (FEA). MATERIALS AND METHODS: Computed tomography (CT) images of a healthy 35-year-old male patient who had no history of trauma or fracture were modeled in three-dimensional (3D) with Mimics® software for the lumbosacral spine model. Ligaments and discs were created on the 3D spine model in the SolidWorks® program. The obtained model was sent to the ANSYS version 18 software, and analyses were done non-linearly. All analyses were performed at different angles and forces from the center of the sacral surface to simulate traction therapy. RESULTS: Traction forces applied in the 0° axial direction decreased the intradiscal pressures by creating a similar tensile stress in the annulus fibrosus regions (anterior, posterior, and lateral) without any significant change in lordotic angle. CONCLUSION: The method used in this study is promising to investigate the benefits of traction therapy. Moreover, individual traction force and direction can be determined to increase the effectiveness of the treatment by using magnetic resonance imaging or CT images in traction therapy.

Technical trick in suture-button suspensionplasty for the treatment of thumb carpometacarpal arthritis.

Suture-button suspensionplasty has been popularized in the treatment of thumb carpometacarpal (CMC) arthritis in recent years. The surgical technique of this method was well defined previously. The most challenging and important part of this technique is the tensioning of the suture-button system to preserve first metacarpal height after trapeziectomy. In present study, we would like to present a technical trick about adjusting the tension while performing suspensionplasty using suture-button device in thumb CMC joint osteoarthritis. In the original technique, trapeziectomy is performed prior to fixation and tensioning of suture-button system. However, it is quite difficult to recreate the original trapezial space, since first metacarpal subsides after trapeziectomy. The trick in our technique is that trapezium remains in its anatomic position up to the end of the operation. Thus, we do not need to make effort to adjust the thumb ray height and use fluoroscopic imaging to ensure its position. In conclusion, we believe that our technique simplifies the most challenging part of the operation, shortens the operation time, preserves the original first ray height and diminishes the exposure of ionizing radiation as it reduces the need for fluoroscopy.

The value of doppler ultrasound in predicting arterial injuries of the penetrating forearm trauma.

OBJECTIVE: The aim of this study was to determine the diagnostic value of Doppler ultrasound (DU) in predicting arterial injuries following the penetrating trauma of the forearm, by comparing preoperative diagnosis made by DU and that made by physical examination (PE) with the intraoperative diagnosis. METHODS: In this retrospective study, 48 patients (44 men, 3 women; mean age = 30 ± 12.5 years) who underwent surgical treatment due to a suspected arterial injury following a penetrating trauma in the forearm from 2016 to 2018 were included. The DU examination was frequently done before an orthopedic examination. In the orthopedic PE, the knowledge as to whether an arterial injury occurred or (if present) which artery was injured was noted. Preoperative diagnoses by PE and DU were first compared with each other, and then with the intraoperative diagnoses. The specificity, sensitivity, negative and positive predictive values were calculated. RESULTS: While the DU findings from 24 patients (50%) matched their intraoperative results, the result from the remaining 24 patients (50%) did not. Nine (18.75%) were considered false-positive and 15 (31.25%) were false-negative. Whereas the PE findings from 30 patients (62.5%) matched their intraoperative results, the remaining 18 patients (37.5%) did not. Six (12.5%) were considered false-positive and 12 (25%) were false- negative. No significant difference was found between the diagnoses of DU and PE, and there was good agreement between the DU and PE findings (P = 0,065, κ = 0,504). While the DU findings were significantly different from the intraoperative findings (P = 0.004), the PE findings were not significantly different from the intraoperative findings (P = 0.302). Sensitivities of DU and PE were both 75% for the diagnosis of radial artery injury as well as 63.3% and 70% for the ulnar artery injury, respectively. Specificities of DU and PE were 83.3% and 91.66% for the diagnosis of radial artery injury as well as 77.77% and 72.22% for the ulnar artery injury, respectively. CONCLUSION: The PE seems more sensitive and useful than the DU in predicting arterial injuries following the penetrating trauma of the forearm. LEVEL OF EVIDENCE: Level IV.

Long-term clinical outcomes of innervated digital artery perforator flap in the treatment of fingertip injuries.

OBJECTIVE: The aim of this study was to evaluate the long-term clinical outcomes of innervated digital artery perforator (IDAP) flap in the treatment of patients with fingertip injuries. METHODS: Eighty-three patients (93 fingers; 70 male, 13 female; mean age = 35.2 years, age range = 5-65) with fingertip injuries who underwent acute or late reconstruction with IDAP flap between 2011 and 2016 were retrospectively reviewed. The mean age was 35.2 (range = 5-65) years. Reconstructions performed in 85 fingers (91.4%) were acute, and 8 fingers (8.6%) were late. Hypersensitivity, cold intolerance, and patient satisfaction were questioned as subjective evaluation parameters. The objective patient outcome evaluations consisted of static two-point discrimination (s2PD) test, the Semmes-Weinstein monofilament (SWM) test, and range of motion of the reconstructed fingers. RESULTS: The mean follow-up period was 33.1 (range = 12-62) months. The smallest flap size was 1.6 x 0.7 cm; the largest flap size was 4 x 2 cm. All flaps survived completely. There was no postoperative infection or donor site morbidity. Hyperesthesia was observed in 4 fingers (4.3%), of which 3 were mild and 1 was moderate. Eighteen patients (18 fingers, 19.3%) experienced mild cold intolerance on reconstructed fingertips. 75 patients (90.3%) were highly satisfied, and 8 patients (9.7%) were satisfied with functional and aesthetic results of their fingertip reconstructions. No range of motion limitation was observed in any joints of 90 fingers (96.8%). The s2PD in the flaps ranged from 2mmto 6mm(mean = 3.71 ± 0.97 mm), compared with 2mmto 5mm(mean = 2.73 ± 0.66 mm) on the contralateral hand. TheSWMtest results of the flaps ranged from 2.44 to 4.56, compared with 2.44 to 4.31 on the contralateral hand. The difference regarding s2PD and SWM test was statistically significant (P < 0.001). CONCLUSION: IDAP flap seems to be a sensate, reliable, and versatile flap that can be used in acute and late reconstructions of any type of fingertip defects. Satisfactory functional and aesthetic results can be achieved with better sensorial results and lower complication rates compared to other conventional reconstruction techniques. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

Repair versus biceps tenodesis for the slap tears: A systematic review.

PURPOSE: The ideal treatment algorithm is still controversial for Superior Labral Anterior-Posterior (SLAP) tears. In this systematic review, we aimed to clarify and ascertain which treatment modality is effective and more usable in which conditions. METHODS: In this systematic review, we used the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines established for systematic reviews and meta-analysis. "SLAP or Superior Labral Anterior-Posterior" and "biceps tenodesis" search terms were used in The Cochrane Library database and Pubmed from their inception to the 30th of September 2020. A total of 2326 titles were screened and 2069 articles were removed because of their ineligibility. Full texts of 14 studies were screened and finally, six were suitable for the present systematic review. Demographic details and study characteristics, patient satisfaction, functional outcomes, return to preinjury sports level, reoperation, stiffness, sling time and rehabilitation protocols were reviewed and compared between SLAP repair and biceps tenodesis groups. RESULTS: A total of 2326 titles were screened and six studies were detected eligible. Results of 287 patients (SLAP repair: 160, Biceps Tenodesis: 127) were reviewed in included six studies. Biceps tenodesis was showed as more satisfied technique in four of the studies but the statistical comparing results of two groups were not significantly different in each study. Different functional scoring systems used in the studies were not statistically significantly different between the groups. The percentage of return to sport and preinjury level is higher in biceps tenodesis in the five studies. The total reoperation rate for SLAP repair was 19/160 (12%) and biceps tenodesis was 7/127 (6%). CONCLUSION: The biceps tenodesis has a higher return to preinjury sports level, higher patient satisfaction and lower reoperation rates but functional scores are similar between SLAP repair groups in patients with SLAP tear.

Comparison of two surgical techniques for the treatment of transverse olecranon fractures: A finite element study.

BACKGROUND: In this study, we aimed to compare the stability of traditional tension band wiring (TBW) and screw combined TBW (SC-TBW) fixation methods performed for a transverse olecranon osteotomy-fracture during different degrees of elbow movement by using finite element analysis. METHODS: Three-dimensional solid modeling of the olecranon was obtained by computed tomography images. Transverse olecranon fracture was created and fixed by TBW and SC-TBW with respect to triceps muscle force. Opening angle, twisting angle and interplanar translation occurring on the fracture line were evaluated at 45° and 90° elbow flexion. RESULTS: Opening angle: 0.71°, 0.87° at 45° and 0.64°, 0.67° at 90° elbow flexion for TBW and SC-TBW, respectively. Twisting angle: -0.01°, -0.19° at 45° flexion and 0.19°, 0.30° at 90° flexion for TBW and SC-TBW, respectively. Interplanar translation: 1.93 mm, 4.65 mm at 45° flexion and 1.78 mm, 3.95 mm at 90° flexion for TBW and SC-TBW, respectively. CONCLUSION: TBW fixation provides more stability than SC-TBW fixation model.

Evaluation of glenohumeral range of motion and humeral retroversion at ages after major change and differences in wrestlers.

PURPOSE: This study aimed to present the change in humeral retroversion (HR) angle (HRA) that occurs in childhood and young adulthood and the potential developmental difference that is observed in wrestlers. METHODS: HRA of dominant and non-dominant shoulders (DSHRA and NDSHRA, respectively) were measured using ultrasonography in a group of 30 wrestlers who started wrestling before the age of 13 years (Group 1), a group of 30 young adults, aged between 16-20 years, who were not actively engaged in any branch of overhead sports (Group 2) and a group of children aged between 11-13 years and not actively engaged in any branch of overhead sports (Group 3). Range of motion (ROM) degrees of dominant and non-dominant shoulders in all groups were compared within each group and between the groups. RESULTS: DSHRA (mean: 88.73°, 88.93° and 89.40°) values were significantly higher than NDSHRA (mean: 81.13°, 81.83° and 84.37°) values (p < 0.001, p < 0.001 and p < 0,05) in Groups I, II and III, respectively. Internal rotation and total ROM degrees of the dominant shoulder in Group 1 and 3 were higher than those in Group 2. CONCLUSION: There is no significant change in terms of HRA in people aged between 11-13 and 16-20 years because of natural development or wrestling. DSHRA values are higher than NDSHRA ones. In contrast to the shoulders of throwers, the shoulders of wrestlers are characterized by an increase in internal rotation, described as "Wrestler's shoulder." LEVEL OF EVIDENCE: Level III.

Treatment of scaphoid nonunion with 1,2 intercompartmental supraretinacular artery vascularized graft and compression screw fixation.

PURPOSE: Aim of the present study was to evaluate the clinical, functional, and radiological outcomes of 1,2-intercompartmental supraretinacular artery (1.2-ICSRA) vascularized graft technique together with compression screw fixation for the management of scaphoid nonunions. METHODS: A retrospective study was designed to evaluate the medical records of the 21 patients treated with 1,2-ICSRA vascularized graft for established scaphoid nonunion of the waist or proximal pole between 2015 and 2018. Seventeen patients who met the criteria were included in the study. The retrospectively analysed demographic parameters included age, gender, injured hand (dominant/non-dominant), aetiology of the injury, delay between injury and operation, initial treatments following the fracture, tobacco use, and background diseases that may affect healing (diabetes, vasculopathy etc.). Radiological and clinical examinations were routinely performed 2 weeks, 6 weeks, 3 months and 6 months after surgery and during the final follow-up. Postoperative clinical and functional outcomes at the latest follow-up were evaluated by measuring active wrist range of motion, grip strength, Turkish version of Quick Disabilities of the Arm, Shoulder and Hand Questionnare (Quick DASH) and Mayo Wrist scores and comparing them with preoperative values. RESULTS: All 17 patients were male with an average age of 26.82 ± 4.08 years (range 20-35 years). The fracture site was located in the scaphoid waist and proximal pole in 5 (29.4%) and 12 (70.6%) patients, respectively. Avascular necrosis was observed in 13 patients (2 at the waist, 11 at the proximal pole). The mean follow-up duration was 18.88 ± 11.98 months (range 6-44 months). No graft extrusion occurred, and no other complication was observed in any of the patients. Amongst the 17 patients, 15 (88.2%) achieved union. The total wrist motions of patients were better postoperatively than preoperatively. However, only improvement in wrist extension was found to be statistically significant. Quick DASH and Mayo Wrist scores of the patients and grip strength were significantly improved postoperatively. CONCLUSION: The 1,2-ICSRA vascularized graft technique together with compression screw fixation offers an easy and reliable option for the treatment of scaphoid nonunions with a high union rate and good functional and clinical outcomes. LEVEL OF EVIDENCE: IV Therapautic.

Pediatric tibial shaft and distal metaphyseal fractures.

OBJECTIVES: This study aims to investigate the effects of associated factors like age, fracture level, accompanying fibular fractures and wound condition on healing by determining and comparing union scores of pediatric tibial fractures (PTFs). PATIENTS AND METHODS: Forty-five patients with 46 PTFs (32 males, 13 females; mean age 9.5 years; range 2 to 16 years) who were treated by closed reduction and casting or operated between January 2016 and January 2019 were retrospectively evaluated. The union scores were evaluated at the end of fourth, sixth and eighth weeks and compared to each other. Effects of the age, associated fibular fractures, wound condition, fracture level and treatment type to union score were analyzed. RESULTS: Twenty-eight (60.9%) out of 46 PTFs had associated fibular fractures and 18 (39.1%) did not. Motor vehicle accident was the most frequent etiologic factor (47.8%). Thirty-four out of 46 fractures were closed tibial fractures (73.9%) and 12 had open wound (26.1%). There was a negative correlation between age and the union scores (p<0.001 for each week). No significant difference was observed between the union score of diaphyseal and metaphyseal fractures at the fourth, sixth, and eighth weeks. The union scores of each week were higher in the conservative group compared to operative group (p<0.001 for each week). Associated fibular fracture group had lower union scores compared to isolated tibial fracture group at fourth, sixth and eighth weeks. Likewise, the union scores of the open fracture group were lower than the closed fracture group (p<0.05 for each week). CONCLUSION: Associated fibular fractures, open fractures and aging negatively affect union scores of PTFs. Attention should be paid, particularly in these conditions, during the selection of the operation type and the follow-up period of PTFs.

Long-term results of arthroscopic medial reefing for patellar instability.

BACKGROUND: The purpose of the study was to investigate the long-term outcomes of the all-inside arthroscopic medial reefing (AAMR) procedure for patellar instability and the factors that affect successful outcome. METHODS: In this retrospective study, AAMR with suture was performed in 16 knees of 15 patients who had at least one patellar dislocation and did not experience a decrease in pain and who did not have a major radiological bony abnormality. Preoperatively, Tegner and Lysholm scales were used; for the final evaluation Tegner, Lysholm, Kujala and Knee injury and Osteoarthritis Outcome Score (KOOS) were used. RESULTS: The average age of the patients at the time of operation was 18 years (range: 11-36 years). The average follow-up time was 118.3 months (range: 85-143 months). Six of the 16 knees (37.5%) exhibited re-dislocation. Preoperatively, the mean Lysholm and Tegner were 66.5 and 4.0, respectively; and postoperatively increased to 89.3 (P = .001) and 4.66, respectively. At the final follow-up, mean Kujala was 89.3 (good), and mean KOOS was 91.4. In all patients with re-dislocation, fewer than four knots were used, and none of the patients with four knots exhibited re-dislocation. Re-dislocations occurred in two, two, one and one patients at two, three, five and eight years, respectively. CONCLUSIONS: The AAMR technique is associated with minimal incisional scarring and an increase in functional scores. It is also associated with a high risk of re-dislocation compared with other methods. If the technique still needs to be used, despite the high re-dislocation rate, at least four knots should be applied.

Tenolysis rate after zone 2 flexor tendon repairs.

OBJECTIVES: This study aims to evaluate the tenolysis rates of zone 2 flexor digitorum profundus (FDP) with flexor digitorum superficialis (FDS) tendon repairs using four-strand technique and early passive motion exercises. PATIENTS AND METHODS: In this retrospective study, we performed zone 2 flexor tendon repairs in 149 patients (117 males, 32 females, mean age 33.3±12.9 years; range, 13 to 72 years) (82 right and 67 left hands) between November 2014 and January 2019. A total of 194 FDP and FDS tendons were repaired primarily by using modified Kessler and Bunnell methods. Patients underwent pure passive motion protocols after surgery according to modified Duran's protocol. No active flexion components were added until postoperative fourth week. RESULTS: Twenty-three out of 149 patients and 28 out of 194 fingers (14.43%) had tenolysis. There was no significant relationship between the number of operated fingers, gender, and tenolysis rate (p=0.836, p=0.584, respectively). CONCLUSION: The repair of the FDP with FDS tendon increases the tenolysis rate in zone 2. The tenolysis rate does not change according to the number or distribution of injured fingers and gender of the patient.

Tumorous conditions of the pediatric hand and wrist: Ten-year experience of a single center.

OBJECTIVES: This study aims to evaluate the distribution and prevalence of pediatric hand tumors and tumor-like lesions according to age and gender. PATIENTS AND METHODS: We retrospectively examined the details of hospital records of 646 patients who were operated for hand mass between January 2009 and January 2019 and whose pathological diagnosis was established in the same hospital. A total of 54 patients (18 males, 36 females; mean age 12.07 years; range, 3 month to 17 years) under 18 years of age who had been operated for the wrist or hand mass were included in the study. RESULTS: Out of 54 tumors, 53 were benign (98%) and one was malignant (2%). There were 42 soft tissue tumors (78%) and 12 bone tumors (22%). The most common soft tissue mass was ganglion cyst (n=12). Six out of 12 ganglion cysts were on the dorsal side of hand or wrist and six were on the volar side. The distribution of the tumors according to gender was not statistically significant (p=0.73). We had two recurrences: one patient with giant cell tumor of the tendon sheath and one with palmar fibromatosis. CONCLUSION: Pediatric hand/wrist masses are mostly benign tumorous conditions. The location of the pathologies may be different from the adults. Diagnosis of the tumor should be established carefully clinically and radiologically while malignant tumors should be kept in mind by both pediatricians and orthopedic surgeons.

Glomus tumors of the nail bed: topographic anatomy and an algorithmic approach based on the topography.

PURPOSE: Glomus tumors are rare vascular pathologies characterized by a triad of symptoms: tenderness, pain and cold intolerance. In the hand they are highly concentrated under the nail bed. In this retrospective study, we aimed to present a topographic map of the location of glomus tumors in the nail bed and a map-based surgical approach algorithm to the subungual glomus tumors. METHODS: We prepared a nail bed map with 6 zones and named these zones as ulnar distal, ulnar proximal, central distal, central proximal, radial distal and radial proximal. With respect to the tumor location and the used surgical approach we retrospectively evaluated the intraoperative photos and the hospital records of patients who were operated between 2008-2019 and had the pathological diagnosis of glomus tumor. The examination records of the postoperative first year were evaluated for each patient retrospectively. A descriptive statistical analysis was performed. In addition we analyzed the described surgical approaches to excise a glomus tumor in the nail bed. The described approaches and the approaches used by us were matched with the localisation of the tumors in this study developing an algorithm for the surgical approach depending on the localisation of the nail bed glomus tumor. RESULTS: Finally 44 patients had inclusion criteria. The distribution of the glomus tumor was as follows: 2 were on ulnar distal (4.5 %), 9 on ulnar proximal (20.5 %), 1 on central distal (2.3 %), 18 on central proximal (40.9 %), 4 on radial distal (9.1 %) and 10 were on the radial proximal zones (22.7 %). 4 lateral approaches, 1 nail sparing and 39 transungual approaches were performed. We had one recurrence in a male patient operated by transungual approach. CONCLUSION: Glomus tumors are mostly located on the central proximal part of the nail bed. Our glomus map and the algorithm we described might be helpful for the selection of the surgical approach for the glomus tumor.

Acetabular fractures treated surgically: Which of the parameters affect prognosis.

BACKGROUND: This study aims to evaluate the surgical approaches, complications, clinical and radiological findings in acetabular fractures treated with surgical methods and to determine the parameters affecting prognosis. METHODS: Out of 144 patients undergone surgical treatment with the diagnosis of displaced acetabular fractures between 1994 and 2014, a total of 103 patients with 75 male and 28 female with a mean age of 36.3 years (range 19-67 years) whom clinical and radiologic follow-ups (mean: 34 months, range 2-8 years) were performed at least for two years were included in this study. RESULTS: Clinically excellent to good outcomes were obtained in 64% of the patients and moderate to poor outcomes were recorded in 36% of the patients, while radiologically excellent to good outcomes were achieved in 57.3%of the patients and moderate to poor outcomes were recorded in 42.7% of the patients. Presence of one of the complications, creating mechanical block (chi-square p<0.001), complex fractures (chi-square p=0.023), increased duration between trauma and operation (p=0.039), operational time taking longer than six hours (chi-square p<0.001), more than 3 mm intra-articular step (Fisher's p=0.033), avascular necrosis (p<0.001), arthritis (p=0.006) and heterotopic ossification (p=0.007) worsened the clinical outcomes (chi-square p<0.001). The age of the patient was not effective on the clinical outcome (p=0.461). CONCLUSION: It was found that three major parameters affecting the prognosis of acetabular fractures are as follows: type of fracture, operational time and reduction quality. The duration between trauma and operation indirectly affects the outcomes. Avascular necrosis, heterotopic ossification and arthritis may cause negative effects only on long term outcomes.

Sesamoid bones of the hand: A multicenter study.

OBJECTIVES: This study aims to document a detailed investigation on the sesamoid bones (SBs) of Turkish subjects from different parts of Turkey in a multi-center study, in both hands, according to gender, frequency and divisions of the bones' coexistence and bilaterality by radiography. PATIENTS AND METHODS: This retrospective and three-centered study was performed between June 2010 and April 2012. Sesamoid bones were examined by anteroposterior and oblique X-rays of 1,444 hands of 772 subjects (367 males, 405 females; mean age 42.7 years; range, 18 to 87 years). All X-rays were evaluated by at least two independent observers. In controversial circumstances, at least three observers together gave the final decision by consensus. RESULTS: Metacarpophalengeal (MCP) joint of the thumb (MCP 1) had sesamoid in all subjects (100%) and it was seen bilaterally. The prevalence of the SB was 42.8% in the second MCP joint (MCP 2) in 772 subjects and 36.6% in 1,444 hands, 1.6% in the third MCP joint (MCP 3) for the subjects and 1.1% for the hands, 0.1% in the fourth MCP joint (MCP 4) for the subjects and 0.1% for the hands, and 72.5% in the fifth MCP joint (MCP 5) for the subjects and 62.5% for the hands. The prevalence of SB in the first interphalangeal joint (IP 1) was 21.8% and SB was detected in 18.6% of the hands. Sesamoid bones of the MCP 2, MCP 5, and IP 1 was recorded more frequently in females. Sesamoid bone of the same joints (MCP 2, MCP 5 and IP 1) was detected more frequently bilaterally than unilateral right side and more frequently unilaterally on right side than unilateral left side. CONCLUSION: The distribution of SBs varies according to hand regions, gender, and side. Having knowledge of the locations and the rate of bilaterality of SBs may assist clinicians in both clinical and radiological diagnoses.

Biomechanical comparison of double versus triple button reconstruction techniques in patients with acromioclavicular joint dislocation.

BACKGROUND: Although many techniques are used to treat the acromioclavicular (AC) joint dislocations, minimal invasive or arthroscopic coracoclavicular ligament reconstructions became popular recently. In this study, authors compared the biomechanical results of double versus triple button reconstruction techniques. METHODS: Three-dimensional solid modeling of the shoulder girdle was carried out using virtual finite element modeling. AC joint dislocation was applied to the reference model, and these models were repaired by double and triple button techniques, respectively. Maximum equivalent stresses on buttons and sutures as well as displacements and reaction forces on AC joint were evaluated. RESULTS: Triple button model was more stable during flexion and abduction when compared with double button technique. CONCLUSION: Mimicking conoid ligament has a crucial mission more particularly against resistance during frontal plane actions, but the absence of the trapezoid ligament causes increasing the posterior displacement of the distal clavicle during the flexion of GH joint.

Results of Peroneal Tendoscopy With a Technical Modification.

BACKGROUND:: The aim of this study was to evaluate the role of tendoscopy in the diagnosis and treatment of peroneal tendon (PT) pathologies, and to evaluate the results of our technical modification. METHODS:: Twenty ankles of 18 patients with retrofibular pain, operated on between 2006 and 2012, were included in this study. Peroneal tendoscopy was performed diagnostically for the patients who were diagnosed as having "peroneal tendinopathy" with physical examination, x-ray, or magnetic resonance imaging (MRI). After being diagnosed by peroneal tendoscopy, patients were definitively treated with either tendoscopy or open surgery. RESULTS:: Thirteen of 20 ankles had accompanying ankle pathology with PT pathology, and the other 7 ankles had no concomitant pathology. We detected peroneal tenosynovitis (PTS) in 13 patients, PT tear in 7 patients, and vincula thickening in 1 patient. The American Orthopaedic Foot & Ankle Society (AOFAS) score was 76 preoperatively, and after 2 years' follow-up the AOFAS score was 96. CONCLUSION:: Tendoscopy is a useful method for the diagnosis and treatment of PT pathologies. The patients with clinical suspicion of PT pathology were treated or diagnosed by peroneal tendoscopy with our technical modification. LEVEL OF EVIDENCE:: Level IV, retrospective case series.
