Purpose of the study: The study aimed to evaluate the results of closed reduction and epiphyseodesis of unstable slips of the proximal femoral epiphysis. The hypothesis was that the clinical and radiological results of this method and incidence of avascular necrosis are comparable to the results of closed reduction and open reduction using surgical hip dislocation reported by literature.

Material and methods: In the period 2013-2023, 20 patients were treated for unstable slips in one institution. Whereas the boys were older (mean age of 13.4 years) than girls (mean age of 11.6 years), the gender distribution was equal. Acute on chronic slips prevailed over the acute slips (ratio 3:1). The slips were treated using the closed reduction, transphyseal fixation and capsular decompression at 6 to 240 hours after slip (81 hours on average). All patients were treated concurrently on the contralateral side as the prevention of the slip or to treat the grade I slips (two patients). The follow-up ranged from 7 months to 7 years. Clinical results were evaluated according to two scores: 1) own score (Bulovka University Hopspital score) based on the reduction of ROM, shortening of extremity and limitations of activities; 2) D'Aubigne-Postel score. In the radiological evaluation, correction of slip angle, alpha-angle, avascular necrosis (AVN) and the prominence of the anterior margin of the femoral neck on axial radiographs were evaluated.

Results: According to the Bulovka University Hospital score, there were 10 excellent results (50%) with no limitation of activity, including sport, in tree cases the results were very good (15%) and in five cases good (25%), respectively, with some limitation of activity, and two results were unsatisfactory (10%) with severe limitation of activity due to the AVN. According to the D'Aubigne-Postel score, there were 14 excellent results (70%), four good results (20%), and two unsatisfactory results (10%). The slip reduction was as follows: under 20 deg. in five patients; under 30 deg. in 10 patients, and over 30 deg. in five patients, respectively. Alfa-angle was greater than 63 degrees (range 45-88 deg.) on average. Prominence of the off-set epiphysis-femoral neck and femoroacetabular impingement (FAI) were observed in six patients. Remodelling of this prominence was seen in one patient four years after surgery. Shortening of the femoral neck over 1 cm was reported in two patients. Complete AVN with severe deformity of the hip was noted in two patients.

Discussion: Our hypothesis was confirmed because the results of treatment of the unstable slips by closed reduction are comparable with the published results of the same method and with surgical hip dislocation. The results correspond with those of large published cohorts of patients concerning the correction as well as rate of complications.

Conclusions: According to

Purpose of the study: Os vesalianum pedis (OVP) is a rare accessory bone of the foot located at the base of the fifth metatarsal bone. It is usually asymptomatic and incidentally seen on radiographs. When symptomatic, it manifests itself with lateral foot pain. OVP, which can become symptomatic as a result of traumatic injuries, can also be confused with fracture. The aim of this study is to determine the prevalence and morphometric characteristics of OVP in the Turkish population.

Material and methods: Radiographic images of 5268 individuals aged 16 years and older (mean 39.65±17.21) who completed ossification of the fifth metatarsal bone were evaluated for OVP. Of the cases included in the study, 44.8% were female and 55.2% were male. The general and sex-based prevalence of OVP was calculated, and morphometric measurements were done.

Results: OVP prevalence in the Turkish population was found to be 0.15% regardless of sex. OVP prevalence was calculated to be 0.24% in men and 0.04% in women.

Conclusions: Anatomy, radiology, orthopedics and emergency medicine physicians are frequently encountered with foot disorders in clinical and educational practices. It is important to keep in mind the rare presence of OVP (0.15%), in the preliminary diagnosis.

PUSPOSE OF THE STUDY. Many studies have investigated the efficacy of peroneus longus tendon (PLT) in anterior cruciate ligament (ACL) reconstruction, and donor site morbidity has not been adequately studied.

Material and methods: Fifty patients who underwent ACL reconstruction using PLT were included. Ankle strengths of the patients evaluated with an analog dynamometer. Ankle range of motion (ROM) was measured with a smart phone inclonometer application.

Results: There was no significant difference between the postoperative ankle strength(eversion, plantar flexion) in the donor area and the preoperative period (p=0.6 and p=0.7, respectively) and contralateral healthy side (p=0.6, p=0.6, respectively). Ankle ROM angles (dorsiflexion, plantar flexion, eversion, inversion) were significantly lower in the post-operative period compared to the preoperative period and contralateral healthy side (p<0.05, p<0.05, p<0.05, p<0.05, respectively). There was no significant difference between pre-operative and post-operative AOFAS scores (p=0.2).

Conclusions: Although PLT can affect ROM angles, it is a promising alternative for ACL reconstructions without causing functional morbidity.

Purpose of the study: The purpose of this study was to assess the patient experience of trapeziectomy under WALANT for trapeziometacarpal joint (TMJ) osteoarthritis (OA) in a prospective study with 2-year follow-up.

Material and methods: The study included 23 patients with TMJ OA undergoing trapeziectomy with WALANT. All patients were seen by a hand therapist preoperatively and at 3, 12, and 24 months postoperatively. At each visit, VAS pain scores, thumb range of motion, grip strength, and Disabilities of the Arm, Shoulder and Hand (DASH) score were assessed. The Picker Patient Experience (PPE-15) questionnaire was administered within 2 weeks of surgery.

Results: All 23 patients completed the PPE-15 questionnaire. Their mean age was 64 years. The 21 patients who remained at the 24-month follow-up all said they would choose the same anaesthesia method again. At this follow-up, VAS pain scores, thumb range of motion, key pinch grip and DASH scores had improved significantly, while thumb opposition and hand grip strength remained largely unchanged. The majority of patients felt well informed before and during the procedure, and all patients rated pain relief as good or satisfactory. Nearly 40% of patients reported receiving inadequate information about the postoperative medications.

Discussion: Patients have a positive attitude to trapeziectomy with WALANT, and seem to prefer WALANT over other methods of anaesthesia. Trapeziectomy with WALANT for TMJ OA is a safe procedure and appears to give a functional outcome similar to trapeziectomy under general anaesthesia.

Conclusions: Trapeziectomy with WALANT for TMJ OA is safe, preferred by patients and has similar clinical outcome as trapeziectomy in general anesthesia.

Key words: trapeziectomy, osteoarthritis, WALANT.

Purpose of the study: Pelvic reconstructions after massive bone resections are among the most challenging practices in orthopedic surgery. Whether the bone gap results after a trauma, a tumor resection, or it is due to a prosthetic revision, it is mandatory to reconstruct pelvic bone continuity and rebuild the functional thread that connects spine and hip joint. Several different approaches have been described in literature through the decades to achieve those goals.

Material and methods: To this date, 3D-printed implants represent one of the most promising surgical technologies in orthopedic oncology and complex reconstructive surgery. We present our experience with 3D-printed custom-made pelvic prostheses to fulfi ll bone gaps resulting from massive bone loss due to tumor resections. We retrospectively evaluated 17 cases treated with pelvic bone reconstruction using 3D-printed prostheses. Cases were evaluated in terms of both oncological and functional outcomes.

Results: At the last follow-up, local complications were found in 6 cases (36%): in 4 (23.5%) of them the cause was a local recurrence of the disease, whereas only 2 (12.5%) had non-oncologic issues. The mean MSTS score in our population increased from 8.2 before surgery to 22.3 at the latest clinical control after surgery.

Discussion: 3D-printing technology, used to produce cutting jigs and prosthetic implants, can lead to good clinical and functional outcomes. These encouraging results are comparable with the ones obtained with other more frequently used reconstructive approaches and support custom-made implants as a promising reconstructive approach.

Conclusions: Our data confi rm 3D-printing and custom-made implants as promising technologies that could shape the next future of orthopedic oncology and reconstructive surgery.

Key words: custom made prosthesis, pelvic reconstruction, orthopedic oncology, cutting jigs, 3D-printing.

Transphyseal fractures of the distal humerus are usually seen in children younger than 3 years of age and are considered as Salter-Harris Type I epiphysiolysis. Neonatal transphyseal distal humerus injuries are extremely rare. It usually occurs due to trauma during difficult labour but can also be seen after child abuse. Since the distal humerus is composed of cartilaginous tissue in newborns, it is difficult to make a diagnosis with direct radiography. Patients are often diagnosed with elbow dislocation. However, elbow dislocation is almost never seen under the age of 3 years. Transphyseal fractures can be seen as a result of manoeuvres performed to deliver the baby during difficult normal delivery. Transphyseal humeral injuries can also be seen after caesarean section, child abuse and falling on the hyperextended arm. Clinical symptoms include pain, swelling, ecchymosis and crepitation at the elbow. Pseudoparalysis is present due to pain. In children with a history of difficult birth or trauma, evaluation with direct radiography should be performed initially. Radiocapitellar line is distorted on radiographs and the elbow joint appears subluxated. The treatment algorithm for transfusional humeral fractures in neonates is varied. It should be remembered that patients in this age group have a tremendous healing capacity. In conservative treatment, 2-4 weeks of follow-up with a long-arm splint after reduction is sufficient. In addition, closed reduction-internal fixation or open reduction-internal fixation can be applied according to the amount of displacement of the fracture. Cubitus varus, osteonecrosis, growth disturbance, decreased range of motion, compartment syndrome, neurovascular injury and infection are the main complications seen after transfusional humeral fractures.

Purpose of the study: Hand enchondromas are benign cartilage bone tumors. Curettage represents the actual gold standard for hand enchondromas. Little has been written about the effectiveness of curettage on hand functionality.

Material and methods: In this retrospective study, we evaluated the effectiveness of curettage and bone grafting on the hand. For each case, we compared the pre-operative and post-operative QuickDASH of the treated limb. The final functional outcome was also evaluated by calculating the affected finger's Total Active Movement (TAM). Complications and local recurrences were recorded.

Results: Forty-five cases were included in our study. Fifteen of them had a pathological fracture. The mean pre-operative QuickDASH score was 48.4. No intraoperative complications occurred. After a mean follow-up of 38.1 months, the mean QuickDASH score had decreased to 4.4, and the TAM was optimal or sub-optimal. QuickDASH and TAM were significantly better for those with pathologic fractures before surgery. Only 3 cases (7%) had postoperative complications, and 1 (2%) had a local recurrence.

Discussion: Our results prove the effectiveness of curettage and early rehabilitation in increasing and restoring the performances of the treated hands. Our patients experienced a significant improvement in their functionality after surgery, generally passing from a poor to an excellent status. In our cohort, those who had a pathologic fracture before surgery had slightly but significantly worse functional outcomes compared to those who did not suffer pre-operative lesions.

Conclusions: Curettage and early postoperative rehabilitation can lead to good clinical and functional outcomes for hand enchondromas. Patients with pathologic fractures, although slightly exposed to a higher risk of sub-optimal outcomes, can also aim for good post-operative functionality.
