Conservative treatment versus transverse pinning in fifth metacarpal neck fractures in active adults: a randomized controlled trial.

PURPOSE: Compare two simple ways for treating boxer's fractures in active adults; conservative management by ulnar gutter slab and transverse pinning in fixation of fifth metacarpal's neck fracture regarding union, functional outcomes, and complications. PATIENTS AND METHODS: Ninety patients with fifth metacarpals' neck fractures with palmar angulation (30-70°) were managed either conservatively by an ulnar gutter slab or surgically by transverse pinning technique from January 2020 to December 2021. Only 84 patients completed a 1-year follow-up. Patients with old, open, or mal-rotated fractures were excluded. The block-randomization method was used to create equal groups. Patients were evaluated clinically and radiologically every 2-3 weeks until union, then at 6 and 12 months. Functional assessment at the final visit was done using the quick DASH score, total active motion (TAM), and total Active Flexion (TAF). RESULTS: The mean radiological union time for the conservative group in this study was 7.76 weeks, while for the transverse pinning group, it was 7.38 weeks. There was no statistically significant difference between the two techniques regarding union rates and functional outcomes. All patients returned to their pre-injury jobs and level of activity. CONCLUSION: Both conservative management in ulnar gutter slab and percutaneous transverse pinning are considered effective methods in the treatment of simple extra-articular fifth metacarpal neck fractures with angulation between 30 and 70 degrees (AO: 77 A3.1). The functional and radiological results using both methods were satisfactory and statistically comparable.

No correlation exists between coracoid tunnel widening and loss of reduction after arthroscopic acromioclavicular fixation using tightrope system.

PURPOSE: To detect the widening of the tunnel of the coracoid process after arthroscopic fixation of acute acromioclavicular joint (ACJ) dislocation using the TightRope system and its correlation with loss of reduction and functional scores. METHODS: From 2016 to 2018, a prospective study was performed on twenty-three patients with acute grade III-V ACJ dislocation. Arthroscopic TightRope repair of the ACJ was performed. Coracoid tunnel widening was measured by CT, and the coracoclavicular distance was measured on the radiographs immediately postoperatively and at 12 months. The Constant Shoulder Score, Oxford Shoulder Score, Nottingham Clavicle Score and Visual analog scale were used as outcome measures at 12 months. RESULTS: The coracoid tunnel diameter to horizontal coracoid diameter ratio increased from 22.8 ± 3.7% immediately postoperatively to 38.5 ± 5.5% at 12 months (p < 0.001). The coracoclavicular (CC) distance showed an increase from a mean of 10.8 ± 1.7 mm to a mean of 11.8 ± 2.5 at 12 months (p < 0.001). There was no correlation between the increase in the coracoclavicular distance and the patients' functional clinical scores or coracoid tunnel widening. CONCLUSION: Coracoid tunnel widening and radiological loss of reduction occur after arthroscopic fixation of acute ACJ dislocation with the TightRope system. However, they do not correlate with each other or with the functional scores of the patient. LEVEL OF EVIDENCE: Level IV.

Clinical outcomes in stump-preserving versus stump-sacrificing anterior cruciate ligament reconstruction; a randomized controlled study.

BACKGROUND: Anterior Cruciate ligament (ACL) reconstruction (ACLR) aims to restore the anatomy and function of the knee. Although stump preservation during ACLR could be technically challenging, it may improve the revascularization and proprioceptive function of the graft. In this study, we aimed to compare the functional outcome after ACLR with and without stump preservation. METHODS: One hundred and twenty patients with acutely torn ACL and with intact tibial stump were included in this study. Half of them (60 cases) underwent ACLR with stump preservation. The other half (60 cases) had ACLR after total resection of the tibial stump. One hundred and nine out of 120 cases completed their 2 year-follow-up period. All patients were assessed by Tegner activity, Lysholm, and objective International Knee Documentation Committee (IKDC) scores. The side-to-side difference regarding stability was assessed by KT-1000 instrumented Lachman and proprioceptive function was measured by Passive angle reproduction test. RESULTS: There was no statistically significant difference between both groups regarding Tegner activity, Lysholm, and IKDC scores. Knee stability measured by KT-1000 and complication rate also showed no significant difference. But there was a significant difference in proprioception favoring stump preservation. On the other hand, the operative time was significantly shorter with stump resection. There was no significant difference in the complications rate between both groups and there were no cases with stiffness in either group. CONCLUSION: Stump preservation ACLR is a safe technique that yields equivalent functional outcomes to standard ACLR. However; it provides better proprioception. It is more technically challenging, but in experienced hands; it is easily reproducible. TRIAL REGISTRATION: Registration number: NCT05364398 . 06/05/2022.

Simple Cost-Effective Reinsertion of Avulsed Medial Patellofemoral Ligament in Acute Patellar Dislocation.

The medial patellofemoral ligament (MPFL) is the main restraining force against lateral patellar displacement in the first 20° of flexion and is disrupted after patellar subluxation or dislocation. Management of acute patellar dislocations is controversial, and many clinicians opt for conservative treatment in the acute phase. However, a traumatic rupture of the MPFL warrants surgical attention. Several considerations must be made by surgeons attempting reinsertion of the MPFL, including the choice of implant and timing of surgery, to restore the anatomy and biomechanics of the patellofemoral joint. Our aim is to achieve robust reinsertion of the MPFL restoring the anatomy and biomechanics of the patellofemoral joint using a simple, reproducible, and economical technique. We present MPFL reinsertion to the medial border of the patella in an acute patellar dislocation with a braided No. 2 ultrahigh-molecular-weight polyethylene suture (No. 2 Ultrabraid; Smith & Nephew, Memphis, TN) that is passed through 3 transverse parallel tunnels and tied over a bone bridge on the lateral border of the patella. This technique is simple with no implanted hardware, does not have the risk of donor-site morbidity of MPFL reconstruction, and can be performed in skeletally immature patients without growth plate concerns.

Economic Reliable Technique for Tunnel Grafting Using Iliac Crest Bone Graft in Two-Staged Revision Anterior Cruciate Ligament Surgery.

Revision anterior cruciate ligament surgery is a technically demanding procedure. Mal-positioned tunnels together with bone loss and its management are some of the difficulties and challenges faced. Two-staged procedures have successfully been used to tackle those challenges. We present a technique that is safe, reliable, reproducible, and economic in the management of bone defects faced in anterior cruciate ligament revision surgery by using iliac crest bone graft. Preoperative assessment of tunnel position and size is done by computed tomography. Tri-cortical iliac crest bone graft is harvested through a trap door. It is then shaped to fit the tunnels to be filled. It is tapered at the advancing end to facilitate introduction. Mounted on a passing pin and a drill bit, the graft is arthroscopically introduced into the femoral and tibial tunnels. The second stage is performed after the graft has incorporated, as seen on postoperative computed tomography, done at approximately 3 months after the first stage. Iliac crest provides a natural abundant reservoir for bone graft and has all the advantages of being an autograft. With good meticulous technique, complications can be avoided with less donor-site morbidity. This technique is safe, reliable, and reproducible. It provides an ample amount of graft and harvest does not rely on implants; hence, it is economic.

Technique for Fixation of Semitendinosus to the Patella in Patellar Tendon Reconstruction.

Chronic patellar tendon injuries are rare yet challenging to treat. Timing of surgery and graft choices are debatable. Many techniques and methods of fixation have been described with pros and cons. Functional impairment of the extensor mechanism and postoperative complications triggers the quest for finding the ideal technique. In this Technical Note, we use distally based semitendinosus (ST) looped over 2 ETHIBOND sutures. The ETHIBOND is passed through 2 vertical tunnels in the patella and retrieved proximally, docking the ST in a blind tunnel created in the lower pole of the patella. The whip-stitched free ST end is passed through a tunnel behind the tibial tubercle and sutured back to its base. A polyester tape is used to augment the repair in a circumferential manner. Postoperatively full weight bearing is allowed as tolerated in a hinged knee brace locked in extension with only passive range of motion of 0-90° allowed for 6 weeks.

Different Techniques for the Management of Meniscal Ramp Lesions Using Standard Anterior Portals.

There is strong association between meniscal lesions and anterior cruciate ligament injuries. Recently, light was shown on a new entity: ramp lesions. The incidence of these lesions and their management is still unclear. Although some believe that some lesions, when stable, can be managed conservatively, most surgeons repair ramp tears. Accessibility of these tears is challenging; they are best accessed through posterior portals, which is time-consuming and poses potential risk to vital structures. Our technique allows access to and management of ramp lesions through safe standard anterior portals. Ramp lesions are searched for as a routine step during anterior cruciate ligament reconstruction by advancing the scope through the intercondylar notch just beside the medial femoral condyle. If a lesion is found, it is repaired; only very stable small tears are treated with needling to refresh the edges and induce a healing response. A simple suture, horizontal mattress suture, or a circumferential stitch is used.
