Objective: This study aimed to compare the clinical and functional outcomes of reverse shoulder arthroplasty versus arthroscopic supe- rior capsular reconstruction in the treatment of patients with massive irreparable rotator cuff tears and Hamada grade 1-2 glenohumeral arthritis.

Methods: It is a retrospective case-control study comparing the prospective results of 2 different treatment methods. This retrospective comparison of groups was conducted between May 2016 and May 2020. The study included 40 people with massive irreparable rotator cuff tear and Hamada grade 1-2 arthropathy who had arthroscopic superior capsular reconstruction with tensor fascia latae autograft or reverse shoulder arthroplasty surgery. Patients were divided into 2 groups according to treatment. Clinical outcome measures included shoulder range of motion, pain, and functional scores (Constant-Murley, American Shoulder and Elbow Surgeons).

Results: The mean age was 61.85 ± 7.56 and 71.10 ± 6.42 years, respectively, for group I [superior capsular reconstruction (n=20)] and group II [superior capsular reconstruction (n=20)]. The mean follow-up was 22.30 ± 8.4 and 32.50 ± 8.11 months, respectively. In the postoperative data, flexion degrees and Constant scores were significantly higher in the superior capsular reconstruction group (P=.007, P = .043). No significant difference was found between the 2 groups in all parameters (P > .05) except abduction. The increase in abduction value in the reverse shoulder arthroplasty group was significantly higher than in the superior capsular reconstruction group (P = .003). In addition, postoperative data in all parameters in both groups showed significant changes compared to preoperatively.

Conclusion: This study has shown that superior capsular reconstruction with tensor fascia latae autograft can provide clinical and func- tional improvement similar to the reverse shoulder arthroplasty procedure in treating massive irreparable rotator cuff tears with Hamada grade 1-2 arthropathy.

Objective: In traumatic and obstetric brachial plexus injuries, removal of the damaged nerve, repair with the nerve grafts, and nerve transfers are mostly preferred techniques. Success is directly proportional to surgical technique as it is known that end-to-end repair of the peripheral nerves gives better results. The greatest risk in end-to-end repair is the nerve rupture at the brachial plexus repair region and this cannot be detected by conventional radiological techniques.

Methods: Brachial plexus injuries of obstetrical and traumatic patients were operated. If possible and at least one nerve was repaired end to end, follow-up of nerve continuity was done by titanium hemopclip insertion to both sides of the nerve repair area. A new technique nerve repair site marking was developed and end-to-end nerve repair continuity was followed simply by x-ray.

Results: This technique was used for end-to-end nerve coaptions of 38 obstetric and 40 traumatic brachial plexus injuries. Follow-up was done for 6 weeks. Every week patients sent the x-ray of the repair site. Only 3 patients had nerve repair site rupture, and revision surgery was done immediately.

Conclusion: Nerve repair site marking technique and follow-up with only x-ray is a simple reliable, safe, and cheap method that can be applied to any end-to-end nerve repair. This technique has no morbidity or side effects. The aim of the study is to summarize or explain the nerve repair site marking technique used in the brachial plexus region.

Objective: This study aimed to determine threshold values of validated quality of life (QoL) scores, including Oswestry Disability Index (ODI) and Core Outcome Measures Index (COMI), for predicting a successful outcome following surgical treatment of lumbar spondylodiscitis (LS).

Methods: Patients with lumbar spondylodiscitis (LS) undergoing surgery in a tertiary referral hospital were included prospectively from 2008-2019. Data were collected both before surgery (T0) and one year after surgery (T1). QoL was measured using ODI and COMI. The successful clinical outcome was defined by the combination of the following four criteria: no recurrence of spondylodiscitis, back pain ≤4 on visual analogue scale or relief of ≥3 points, absence of LS-related neurological deficit, and radiological fusion of the affected segment. For subgroup analysis, group 1 consisted of patients with a favorable treatment outcome (meeting all four criteria), while group 2 included patients with unfavorable treatment outcome (meeting ≤3 criteria).

Results: Ninety-two LS patients (median age = 66 years; age range = 57-74) were analyzed. QoL scores improved significantly. Threshold values for the ODI and COMI were calculated at 35 and 4.2 points, respectively. The area under curve for the ODI was 0.856 (95%-CI 0.767- 0.945; P<0.001) and 0.839 (95% CI-0.749-0.928; P<0.001) for the COMI score. Eighty percent of patients achieved a favorable outcome.

Conclusion: Objective measurement and evaluation of successful surgical treatment of spondylodiscitis require defined thresholds of quality of life scores. We were able to define such thresholds for Oswestry Disability Index and Core Outcome Measures Index. These can be useful to assess clinically relevant changes and therefore allow a more precise estimation of the post-surgical outcome.

In the past, spinal trauma was frequent in high- and middle-income regions of the world with high rates of automobility and was considered a "young men's disease." However, over the last 2 decades, both of these factors have changed dramatically. This has had important implications for our methods of diagnosis, treatment, and the organization of care.

Objective: This study aimed to determine the risk factors for reconstructive hip surgery after intrathecal baclofen pump application in children with cerebral palsy.

Methods: Inclusion criteria were children with hypertonic (spastic or mixed spastic/dystonic motor type) cerebral palsy, intrathecal baclofen implantation <8 years of age, no reconstructive osteotomies prior to or concomitant with intrathecal baclofen implantation and at least a 5-year follow-up. Exclusion criteria included reconstructive osteotomies prior to or concurrent with intrathecal baclofen implantation, lack of at least 1 hip surveillance radiograph before intrathecal baclofen, lack of a 5-year follow-up, or having selective dorsal rhizotomy. In addition, patients with bony surgery plus last follow-up migration percentage ≥50% were labeled as required reconstruction hips.

Results: We identified 34 patients (68 hips). The mean follow-up was 9.2 ± 2.8 years. The mean age for intrathecal baclofen application was 6.4 ± 1.2 years. Seven patients were Gross Motor Function Classification System IV, and 27 were V. Eighteen patients (52.9%) with 31 hips (45.6%) were requiring reconstruction at the final follow-up. In multivariate analysis, male sex (odds ratio 12.8, P=.012), pre-intrathecal baclofen migration percentage (odds ratio 1.1, P=0.003), age at intrathecal baclofen implantation (odds ratio 0.24, P=.002), and delta migration percentage (odds ratio 1.1, P=.002) were significant risk factors for requiring reconstruction. Patients with intrathecal baclofen <6.2 years of age had a significantly higher rate of requiring reconstruction. A pre-intrathecal baclofen migration percentage >31% had a greater risk of progression to requiring reconstruction (P=.001). Delta migration percentage higher than 15% was significantly associated with progression to requiring reconstruction (P=.043).

Conclusion: The risk of requiring reconstruction osteotomies after intrathecal baclofen was significantly increased in males, those younger (±migration percentage >31%) at the time of intrathecal baclofen implantation and those with an increased rate of migration percentage progression after intrathecal baclofen implantation.

Objective: This study aimed to describe the course, branches, and variances of the posterior tibial artery, which provides the arterial supply of the plantar surface of the foot, starting from the tarsal tunnel level to provide descriptive information for all surgical interventions, diagnostic radiological procedures, and promising endovascular therapies in the tarsal region.

Methods: In this study, a dissection of 48 feet was performed on 25 formalin-fixed cadavers (19 males and 6 females). Surgical instruments and a digital caliper were used for dissection and measurements, and the critical structures were recorded by a Canon 250D camera to be illustrated later.

Results: All parameters were significantly longer in male cadavers compared to females. According to the correlation analysis, while there was a significant and robust correlation between the axial line and pternion-deep plantar arch (R=.830, P .05), a moderate correlation was found between the axial line and sphyrion-bifurcation (R=.575; P < .05), axial line and deep plantar arch-2nd interdigital commissure (R=.457; P < .05), and sphyrion-bifurcation and pternion-deep plantar arch (R=.480; P < .05). Variation in any branch of the posterior tibial artery was observed in 27 of the 48 studied sides.

Conclusion: In our study, the branching and variability of posterior tibial artery on the plantar surface of the foot were described in detail with the determined parameters. In conditions that cause tissue and function loss and require reconstruction, such as diabetes mellitus and atherosclerosis, the most critical factor in increasing treatment success is a better understanding of the region's anatomy.

Variations of the popliteal artery are uncommon but often associated with popliteal artery injuries. Thus, in cases of popliteal artery injury, popliteal artery variations should be one of the primary differential diagnoses. Due to the poor prognosis that may result in amputation or mortality, such injuries are serious complications that can lead to medical malpractice cases. This report presents a case of a 77-year-old woman with bilateral knee osteoarthritis who sustained a popliteal artery injury during total knee arthroplasty due to the highly uncommon type II-C popliteal artery variation. In light of the current literature, the pathology, diagnosis, and treatment of this case of popliteal artery injury, as well as the necessary precautions, have been discussed. The terminal branching pattern of the popliteal artery is essential for surgical planning and the ability to treat accidental artery injuries. To reduce the risk of popliteal artery injury, it is important to discuss the need for preoperative arterial color Doppler ultrasonography and magnetic resonance imaging to reveal the branching pattern and structure (arteriosclerosis and obstruction) of the popliteal artery (arteriosclerosis and obstruction).

Objective: The aim of this study was to investigate the effects of anterior cruciate ligament reconstruction performed by preserving remnant tissue on proprioception and to assess the effects it has on isokinetic quadriceps and hamstring muscle strength, as well as on range of motion and functional scores.

Methods: A prospective study was conducted with 44 patients who underwent either anterior cruciate ligament reconstruction with remnant preservation (study group, n=22) or with remnant excision (control group, n=22) with the use of a 4-strand hamstring allograft. The mean follow-up time was 20.2 ± 1.4 months after surgery. Using an isokinetic dynamometer, proprioception was evaluated with passive joint position perception at 150, 450, and 600, and quadriceps femoris, and hamstring muscle strength were evaluated at speeds of 900, 1800, and 2400 per second. Range of motion was measured using a goniometer. Functional outcomes were assessed using International Knee Documentation Committee subjective knee evaluation score and Lysholm knee scoring questionnaires.

Results: It was only at 15° of knee flexion that there was a statistically significant difference in proprioception; the median of the difference in the amount of deviation from the target angle between the healthy knee and the operated side was 1.7 (range, 0.7-20.7) in those with remnant preserved, and 2.7 (range, 1-26) in those with remnant excised (P=.016). At 2400/s speed, the mean quadriceps femoris strength was 77.2 ± 24.3 Nm in those with remnant preserved and 67.6 ± 24.2 Nm in those with remnant excised. (P=.048) There was no difference between the 2 groups in terms of range of motion, International Knee Documentation Committee, and Lysholm knee scoring. (P > .05) Conclusion: The present study has demonstrated that better proprioception and higher quadriceps femoris muscle strength can be obtained by remnant-preserving anatomical single-bundle anterior cruciate ligament reconstruction using a hamstring autograft.
