Today, intra-articular and juxta-articular osteoid osteomas are treated with arthroscopy and radiofrequency thermal ablation. However, for the case of an elbow joint, arguments are made for the use ...of a minimally invasive technique to be the optimal choice. This study aims to analyse our experiences of arthroscopically treated elbow osteoid osteomas and to compare it with the published results of both techniques.
The retrospective study analyses the patients who underwent elbow arthroscopy ablation of an elbow osteoid osteoma at a single institution from January 2014 until March 2020. Clinical and diagnostic features, success and treatment failure rates, complications and tumour recurrence rates were all compared to 13 studies of intra-articular elbow osteoid osteoma arthroscopic ablation and 15 studies involving radiofrequency thermal ablation of intra-articular osteoid osteoma within different joints.
Four males and two females, with a mean age of 19.3 years, were encompassed. All the patients had immediate postoperative pain relief and improved range of motion. No tumour recurrences were observed during a median of 21.7 months. The literature review yielded 86.4% success rate, 68.2% successful biopsies, one minor complication and no recurrences following the arthroscopic ablation of an elbow osteoid osteoma; while radiofrequency thermal ablation of an intra-articular elbow osteoid osteoma yielded 96.3% success rate, 33.3% successful biopsies, no complications and 3.7% recurrence rate.
Our results are consistent with the published literature proving that arthroscopic ablation is an efficient method with low treatment failure rates and no recurrences in treating intra- and juxta-articular elbow osteoid osteomas. Advantages of arthroscopic ablation stem from the ability to visualise and safely deal with the lesion and the joint's reactive changes resulting in high biopsy rates, no recurrences and better postoperative elbow's range of motion. Still, the technique selection should be personalised considering the medical expertise of every institution.
Background:
We hypothesized that peroneal tendons disorders are more commonly associated with anatomical variations, which could overcrowd the retrofibular groove.
Methods:
This single-center ...retrospective case study covered 84 consecutive cases that had undergone peroneal tendoscopy. Peroneal tendoscopy was performed on 82 patients, predominantly female (3:1) with a median age of 46 years. The preoperative evaluation and all the procedures were performed by a single surgeon using a standardized technique.
Results:
Two patients required revision surgery 8 and 52 months after the index procedure due to persistent posterolateral ankle pain. Peroneal tendoscopy was performed as a solitary procedure in 45.1% (37/82) of cases, while the remaining cases involved peroneal tendoscopy as a supplementary procedure. Low-lying peroneus brevis muscle belly (LLMB) was the most common finding in this series in 53.7% (44/82) of cases. In 41.5% (34/82) of cases, longitudinal tears of the peroneus brevis tendon were noted. Some patients presented with more than 1 concomitant peroneal tendon pathology. The LLMB was observed in 23.5% (8/34) of cases with a longitudinal tear of the peroneus brevis tendon.
Conclusion:
Peroneal tendon anatomical variations, especially LLMB, were associated with the presence of peroneus brevis tendon ruptures and intrasheath peroneal tendon subluxations as well as posttraumatic posterolateral ankle pain. Due to high rates of undiagnosed and misdiagnosed cases of LLMB preoperatively, we believe special care should be taken to recognize it during tendoscopy. Peroneal tendoscopy is a high-efficiency, low-complication method to treat some peroneal tendon conditions.
Level of Evidence:
Level IV, case series.
ankle impingement syndrome. However, other indications of the posterior part of the ankle/hindfoot remain mostly uninvestigated. The aim of this study is to investigate the indications for posterior ...ankle/hindfoot arthroscopy performed as a solitary procedure and to report the outcomes. A total of 71 patients, who had undergone this procedure in our department over a period of nine years, were analysed. In all cases, the van Dijk et al. technique was followed. The most prevalent indication for posterior/hindfoot arthroscopy remains posterior ankle impingement syndrome in 59.15% of cases. Other indications included ten various posterior ankle/hindfoot pathologies, with the subtalar joint contracture being the most common one (15.49%). During the mean follow-up period of 79 (range, 24 - 127) months, there were 2 minor complications noted, both pertaining to transitory sensory deficits. The total median AOFAS Ankle-Hindfoot score significantly improved from 69 to 98, with the improvement noted regardless of the indication. The satisfaction rate with the procedure was 98.59%. This study has shown that posterior ankle/hindfoot arthroscopy is an efficient and safe orthopaedic tool for the treatment of various posterior ankle and hindfoot articular and periarticular pathologies.
Accessory soleus muscle (ASM) is a rare supernumerary anatomical variant that commonly presents as a posteromedial ankle swelling, which may become painful during physical activity. As it may mimic a ...soft tissue tumor, it is essential to differentiate this condition from ganglion, lipoma, hemangioma, synovioma, and sarcoma. However, ASM may also present with a painful syndrome, characterized by pain and paresthesia of the ankle and foot, mimicking the tarsal tunnel syndrome (TTS). Two cases of ASM are presented in this article. The first case had a typical presentation with painful posteromedial ankle swelling. After the initial assessment, the diagnosis was confirmed by magnetic resonance imaging (MRI), and ASM was treated by complete resection. The second case presented with pain and paresthesia in the right ankle and foot, but no swelling was noticeable. It was initially misdiagnosed by a rheumatologist and afterward overlooked on an MRI by a musculoskeletal radiology specialist and therefore mistreated by numerous physicians before being referred to our outpatient clinic. After further assessment, the diagnosis has been confirmed, and ASM was treated by complete resection combined with tarsal tunnel decompression. To the best of our knowledge, this is the first case reported in which ASM caused symptoms but presented without posteromedial swelling. This might be due to a proximally positioned belly of the ASM, followed by a tendinous insertion on the medial side of the calcaneus.
SAŽETAK
Cilj istraživanjaArtroskopija gležnja je kirurški zahvat koji se čini ili kao samostalan zahvat u prednjem, odnosno stražnjem dijelu gležnja ili kao zahvat u kojem se operacija u prednjem i ...stražnjem dijelu gležnja čini u istom aktu. Cilj je ovog istraživanja bio analizirati indikacije, komplikacije i učinkovitost artroskopskih zahvata tijekom kojih je načinjena artroskopija prednjeg i stražnjeg dijela gležnja u istom aktu i usporediti ih s rezultatima drugih istraživanja.
Ispitanici i metodePretraživanjem operacijskih protokola Klinike za ortopediju Kliničkoga bolničkog centra Zagreb i Medicinskog fakulteta Sveučilišta u Zagrebu pronađeno je da je u devetogodišnjem razdoblju načinjeno 169 uzastopnih artroskopija prednjeg i stražnjeg dijela gležnja u istom aktu.
RezultatiNajčešća indikacija za artroskopiju prednjeg i stražnjeg dijela gležnja u istom aktu bio je prednji i stražnji sindrom sraza. Preostale indikacije bile su poslijetraumatska kontraktura, poslijetraumatski osteoartritis te sinovitisi u gležnju različite etiologije. Tijekom promatranog razdoblja uočeno je i zabilježeno u dostupnoj dokumentaciji sveukupno šest poslijeoperacijskih komplikacija. Nadalje, kod trinaest bolesnika operacijski zahvat na gležnju je tijekom praćenja načinjen ponovno.
ZaključakOvo istraživanje govori u prilog činjenici da je najčešće postavljana indikacija za činjenje artroskopije prednjeg i stražnjeg dijela u istom aktu prednji i stražnji sindrom sraza gležnja. Isto tako, ovo istraživanje potvrđuje sigurnost i učinkovitost artroskopskog zahvata u prednjem i stražnjem dijelu gležnja u istom aktu kako kod liječenja sindroma prednjeg i stražnjeg sindroma sraza tako i kod drugih ozljeda i oštećenja u području gležnja, poput poslijetraumatske kontrakture gležnja, poslijetraumatskog osteoartritisa gležnja te sinovitisa u gležnju različitih etiologija.
The goal of the study is to investigate posterior ankle impingement syndrome (PAIS) in the adolescent population and the differ- ences in delay periods for diagnosis. Furthermore, the intention is to ...present the results for arthroscopic treatment of PAIS in adoles- cents and compare them to the results found in published literature. A total of 16 adolescent patients (≤19 years old) included in the study were operated on solely for PAIS. A search was done on avail- able medical documentation primarily for the causes and length of the PAIS symptoms, and any reported complications. The Amer- ican Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score was used to evaluate ankle function, while patient satisfac- tion was measured using the Abdelatif questionnaire. The average age of the patients at the time of the procedure was 16.8 years. The median period from the appearance of the first symptoms until the diagnosis was 8.5 months. No perioperative complications were recorded in the median follow-up period of 75 months. An increase in AOFAS score was noted, ranging from an average of 70.9 preoperatively to 97.0 postoperatively. All of the patients were very satisfied with the results of the procedure, emphasizing postoperative improvement in everyday ankle use. This study confirms the presence of a diagnosis delay for PAIS in the adolescent population, which is in line with the results published in the literature. Additionally, it has been shown that arthroscopic surgery is highly efficient for treating PAIS in the adolescent popu- lation.
Cilj ovog rada jest ukazati na moguću pojavu stražnjeg sindroma sraza gležnja (SSSG) u populaciji adolescenata te provjeriti tvrdnju da se u toj populaciji njegova dijagnoza postavlja s vremenskom ...odgodom. Osim toga, željeli smo prikazati i rezultate provedenog kirur- škog liječenja SSSG-a artroskopskim zahvatom u adolescenata te usporediti dobivene rezultate s rezultatima objavljenim u literaturi. U istraživanju je sudjelovalo 16-ero ispitanika koji su u trenutku zahvata imali ≤19 godina i kod kojih je zbog SSSG-a načinjen artro- skopski zahvat samo u stražnjem dijelu gležnja. Sva dostupna medicinska dokumentacija sustavno je pretražena s ciljem utvrđiva- nja razdoblja od pojave prvih simptoma do točne dijagnoze te uzroka nastanka SSSG-a, kao i traženja zabilješki o komplikacijama liječenja. Na pregledu provedenom u sklopu istraživanja procjena funkcijskog stanja gležnja provedena je upitnikom Američkog ortopedskog društva za stopalo i gležanj (AOFAS upitnik), dok je zadovoljstvo ispitanika načinjenim zahvatom ocijenjeno pomoću Abdelatifova upitnika. Prosječna životna dob ispitanika u trenutku zahvata iznosila je 16,8 godina, a medijan trajanja simptoma do postavljanja točne dijagnoze iznosio je 8,5 mjeseci. Zahvat je u svih protekao bez komplikacija, a one nisu uočene ni u poslijeoperacijskom razdoblju. Utvrđeno je značajno poboljšanje rezultata AOFAS upitnika s prosječno 70,9 prije zahvata na 97,0. Svi su ispitanici izrazili izrazito zadovoljstvo načinjenim zahvatom i istaknuli da im se funkcija gležnja popravila nakon načinjenog zahvata. Ovo je istraživanje potvrdilo konstataciju iz literature da se dijagnoza SSSG-a u populaciji adolescenata postavlja s vremenskom odgodom. Osim toga, ovo je istraživanje potvrdilo iznimnu uspješnost liječenja SSSG-a artroskopskom kirurgijom.
Sindrom kubitalnog kanala susrećemo relativno često te on predstavlja značajan javnozdravstveni problem. Specifičnost tijeka ulnarnog živca niz ruku, a napose anatomski međuodnosi s koštanim i ...mekotkivnim strukturama u području lakta čine ga vrlo podložnim vanjskim utjecajima, ponajviše silama kompresije. Progresija parestezija na ulnarnoj strani četvrtog prsta i na čitavom petom prstu zahvaćene šake uz pojavu motoričke slabosti i atrofije mišića šake uvelike ograničava bolesnike, najčešće one koji se bave aktivnostima koje zahtijevaju da im je lakat duže vremena u fleksiji, da neometano obavljaju svakodnevne aktivnosti. Stoga je iznimno važno pravovremeno dijagnosticiranje sindroma koje se zasniva na iscrpnoj anamnezi i detaljnom kliničkom pregledu uz pomoć niza specifičnih testova koji su detaljno opisani u radu. Elektromioneurografijom možemo utvrditi stupanj kompresije ulnarnog živca te pratiti uspješnost daljnjeg liječenja. Blaži oblici sindroma kubitalnog kanala uspješno se liječe konzervativnim načinom, dok teže oblike sindroma te one koji su neosjetljivi na provedeno konzervativno liječenje treba liječiti kirurški. Metode kirurškog liječenja sindroma možemo podijeliti na one koje ostavljaju živac u ležištu u kubitalnom kanalu poput in situ dekompresije i medijalne epikondilektomije te na one tijekom kojih se živac premješta u novo ležište ispred i iznad medijalnog epikondila, što nazivamo antepozicijom ulnarnog živca. Sve opisane metode pokazale su se gotovo jednako uspješnima, no usprkos tomu istraživanja pokazuju da se u današnje vrijeme kao metoda izbora kirurškog liječenja sindroma kubitalnog kanala najčešće koristi in situ dekompresija.
