RESUMEN
INTRODUCTION: Long finger skeletal fractures are common injuries. In displaced forms, surgical treatment is required. With the advent of headless cannulated screws, the technique has been simplified and allows reduction in both planes. The objective of our study was to evaluate the functional recovery of patients operated on by this technique. MATERIAL AND METHOD: We conducted a retrospective single-center study between 2019 and 2022. Eleven patients were followed and 12 fractures analyzed. A radio-clinical follow-up was carried out at 1 month then at the last follow-up with an evaluation of the articular amplitudes and a quality of life score (QuickDash, QD). The time to return to professional and sporting activities, pain (EVA) was collected. An anatomical/scannographic evaluation was performed to assess tendon and cartilage damage. RESULTS: At the last follow-up, the average global flexion was 266° and the extension was total. An average QD score of 15.9 and a Jamar force of 106% compared to the healthy side were observed. The return to physical and professional activities was earlier and the pain quickly tolerable. No secondary displacement was objectified and all were consolidated at the last follow-up, without malunion. No patient had been operated on secondarily. CONCLUSION: This technique seems to be a safe and non-traumatic. It allows a faster return to sports and professional activities with fewer complications and no need to remove the material.

Trapeziectomy has been considered as the gold standard for treating trapeziometacarpal arthritis. But trapezial space collapse is responsible for thumb strength decrease and intracarpal deformities (with or without tendon interposition). Partial trapeziectomy with interposition of a chondrocostal autograft combines the advantages of trapeziectomy and a biological spacer without the disadvantages of arthroplasty. Partial trapeziectomy is performed by a dorsal approach, under regional anaesthesia. The graft is harvested by a direct approach of the 9th rib during a short bout of general anaesthesia and inserted in the trapeziectomy space. A thumb spica cast is used for 3-6 weeks. In our experience, long-term outcomes and radiological evolution of the graft are good, similar to that of other procedures reported in the literature, except for strength, which is better in this scenario. With more than 5 years of follow-up, the graft is viable, the length of the thumb is maintained, and any areas of graft metaplasia are localized. The result is stable over time and any donor site morbidity is anecdotal. The interposition of a biological material is feasible and produces a stable and strong thumb.

Chronic exertional compartment syndrome (CECS) of the upper limbs is less well known than its equivalent in the lower limbs, thus its diagnosis is often delayed. Our goals were to evaluate the impact of CECS on activities of daily living and work-related activities and to report the functional outcomes after minimally invasive fasciotomy. This was a retrospective study of patients with CECS of the upper limb who were operated at two hospitals between 2008 and 2019. Thirty patients were reviewed an average of 5 years after minimally invasive fasciotomy: 26 had CECS of the forearm, 3 of the thenar compartment and 1 of the first interosseous compartment. For the evaluation, patients were asked to assess their pain on a visual analog scale (VAS), complete the QuickDASH questionnaire and rate their satisfaction with the outcome. Preoperative pain on the VAS was 7.45/10 with a negative impact on activities of daily living in 97% of patients, and on work-related activities in 77% of patients with 17% requiring a career change. The mean time to surgical treatment was 5 years. The mean QuickDASH at the final assessment was 6.0 (0-31.8) with a significant decrease in pain on VAS of 1.9/10 (p < 0.01). Seventy-seven percent of patients had very good results while 13% had good results. Full healing was achieved in 63% of patients and physical performance improved in 50%. Seventy-seven percent of patients were either satisfied or very satisfied with the outcome. One patient had a recurrence requiring surgical revision. CECS affects athletes of all levels and impacts both activities of daily living and work-related activities. We need to greatly expand our education and prevention efforts for CECS. Mini-open fasciotomy yields good results.

The scaphoid is the most common non-union site in the wrist. Fixation with vascularised or non-vascularised autograft is the gold standard when it comes to treating these non-unions. But, what can we offer if the autograft fails? Using osteoinductive proteins in difficult cases of long bone non-union yields good results. However, only a few studies have been published on their use for scaphoid non-union. In our study, five patients with an average age of 32 years (ranging from 21 to 44 years) with old non-union (more than 24 months) of the scaphoid were treated after autograft treatment had failed. The procedure consisted of reaming the non-union site, then adding bone autograft combined with BMP-7 (Osigraft®) in the defect and fixing it all with a screw or K-wire. Postoperative immobilisation was prescribed. Only one patient achieved bone union (20%) despite an average follow-up of 10 years (80-143 months). The average flexion-extension loss was 16.6° (0-30) relative to the contralateral side. The average strength deficit was 450 grams (0-2000) for pinch and 12.1kg (0-29) for grip compared to the contralateral side. Self-assessment questionnaires had an average PRWE at 28.9 (10.5-49) and an average QuickDASH at 28.6 (9.09-61.36). Our study could not demonstrate any real benefit of using BMP-7 for treating old scaphoid non-union despite an elevated cost. Further research is needed to look at other treatment approaches, for instance, the use of new scaffolds combining VEGF and BMP.

The proximal interphalangeal (PIP) joint is particularly vulnerable to trauma. In comminuted fractures, arthroplasty with a silicone implant is a treatment option that may be controversial in an emergency setting. This joint destruction is usually accompanied by soft tissue injuries (skin and tendon damage, devascularization) making the reconstruction all the more complex. The aim of our work was to evaluate emergency finger silicone implants for complex and comminuted fractures of the PIP joint as well as clinical and radiological complications. In this single-center, retrospective study, 13 patients operated between January 2007 and January 2019 on an emergency basis with a Neuflex® PIP arthroplasty were reviewed. This PIP joint reconstruction was associated with the soft tissue repair at the same time (skin cover, tendons, nerves) in all patients. The average age was 57.7 years with a male predominance (92%). The injuries were caused by a domestic accident in 61% of cases. The average follow-up was 4.7 years. The average total active motion arc was 183.8°. The average QuickDASH score was 24. There was one case of broken implant with no functional consequence. No infection or instability was reported. Silicone implant arthroplasty is a simple, reliable, fast, and durable solution for complex PIP fractures when conservative treatment is impossible. This solution is an alternative to arthrodesis or even finger amputation.

There are very few published studies describing the treatment of segmental bone defects of the forearm using the induced membrane technique. The objectives of this study were to evaluate the time to bone union, the function of the joints above and below the treated bone segment and the patients' quality of life over the long-term. We performed a retrospective study in all patients treated by the induced membrane for a forearm bone defect over at 13-year period. Demographics, bone union, complications, functional outcomes and occupational status were collected. Six patients were included: 2 posttraumatic injuries, 1 osteomyelitis, 1 septic arthritis, 1 aseptic nonunion, 1 tumor. The average defect length was 64mm (48-110). All defects were treated with internal fixation. Bone graft was harvested from the iliac crest in two patients, the femur (using the Reamer Irrigator Aspirator technique) in three patients and the radius in one patient. Five patients achieved bone union after a mean of 4months (3-6). Three complications were observed: 1 radioulnar instability, 1 infection of the fixation device, 1 abscess. At an average 8½ years' follow-up, the pain level on the VAS was 0.6 (0-3), the Mayo Elbow Performance Score was 98 (90-100), the Herzberg score was 108 (85.6-140) and the QuickDASH was 14.9 (2.7-35). All patients returned to work. Using the induced membrane technique avoids the complications associated with vascularized autograft and yields good functional outcome and quality of life.

Rib cartilage grafts are widely used in maxillofacial surgery, but not in orthopedic surgery. The aim of this technical note is to describe the technique used to harvest this graft and to report on donor site complications in the 136 cases we have published on up to now. Harvesting is carried out at the osteochondral junction of the eighth rib. The osteochondral junction is located under the external oblique muscle and a perichondrium layer, which is retracted to allow safe harvesting. The amount of cartilage harvested depends on the size of the area being grafted. Harvesting of a rib osteochondral graft is easy to carry out, provides a considerable amount of hyaline cartilage for the reconstruction of degenerative and traumatic lesions on a joint surface and results in few donor site complications.

The goals of distal radius fracture treatment in patients above 65 years of age would not change over time if the fracture were the only factor to consider. However, people change, and fixation methods also change. Since this fracture heals in nearly every case and volar plates have eliminated the worry of malunion, we are left with two main goals. In active patients with weakened bones, the aim is to help them regain their quality of life as quickly as possible while avoiding iatrogenic conditions. This compromise is possible because of new tools-but at what price?

The aims of this study were to evaluate the function and quality of life in patients who have undergone replantation of the hand or forearm. We carried out a retrospective single-center study of cases performed between 1977 and 2015. Our hospital's database was searched for patients who underwent replantation of the distal half of the forearm and hand (except the fingers). The evaluation included sensitivity, joint mobility, strength and quality of life. Conventional functional scores were used. Seventeen replantation cases were identified. Four patients were lost to follow-up. Of the 13 available patients, two suffered a replantation failure. Ultimately 11 patients were included in the study. Three patients were evaluated based on their medical records and eight were reviewed in person. The mean patient age was 31±11.8 years. The sensory evaluation resulted in five patients being classified as S1 and one as S3+. The mean Kapandji score was 4.3±2.3 [0-6]. The mean grip strength was 39.4±20% [0-80], and the pinch strength was 36.2±16% [0-60] compared to the healthy contralateral side. The mean DASH was 36.2±30.4 [4.5-79.5]. According to Chen's classification, two patients were at stage IV. For 50% of patients, the overall quality of life was at least equivalent to that of the general population. Replantation of the distal half of the forearm and hand should be attempted whenever possible. Although replantation causes some disability, good quality of life seems to be maintained.

In the context of lower (C8-T1) brachial plexus injury, transfer of the lateral antebrachial cutaneous nerve (LABCN) to the dorsal branch of the ulnar nerve (DBUN) with an interposed sural nerve graft has been proposed to restore sensitivity on the ulnar side of the hand. The purpose of this study was to assess the feasibility of performing this transfer directly - without interposition of a nerve graft - by intraneural dissection of the DBUN. An anatomical study was performed with 20 upper limbs from adult human cadavers. The LABCN and the DBUN were dissected. The LABCN emerged from the lateral side of the biceps brachii muscle at an average of 2.6±0.4cm from the interepicondylar line and was 13.5±2.6cm long, on average. The DBUN arose from the ulnar nerve 8.2±1.6cm from the styloid process of the ulna. The maximum length of DBUN intraneural dissection relative to the ulnar nerve was 7.5±2.1cm, on average. The LABCN could be transferred to the DBUN in a tension-free manner with end-to-end suturing. Intraneural dissection of the DBUN allows LABCN nerve transfer without interposition of a graft.

INTRODUCTION: The intercostal nerves (ICN) transfer to the musculocutaneous nerve (MCN) can restore elbow flexion in complete brachial plexus palsy. The last cases our service dealt with, allowed our staff to observe two different situations. In the 2 first patients, we were able to proceed with an intraneurodissection of the MCN motor component up to the axillary cavity level, while on the third case such dissection could not be performed as high. The aim of this work is to assess the feasibility of a transfer on the MCN's motor component. MATERIAL AND METHODOLOGY: We conducted a series of 5 cadaver dissections of the MCN and ICN on the anatomy laboratory. Using magnifying loupes to perform an intraneurodissection, we were able to split the motor and sensory fibers as they stood out. It would help motor recuperation avoiding directional error on sensitive component. RESULTS: The ICN can be sutured on the motor component of the MCN, provided the dissection is very minutious. DISCUSSION: The intraneurodissection of the MCN up to the axillary cavity level is possible as the interfascicular exchanges are scarce there. Publications already refer to the possibility of a nerve transfer between the ICN and the motor component of the MCN. Therefore, our researches suggest that such a procedure can be considered for routine procedures. CONCLUSION: The neurotization is one of the latest breakthroughs in terms of brachial plexus surgery. We are hopeful that anatomical researches could lead to optimization possibilities.

None of the classification systems for distal radius fractures is ideal. However a validated system to analyze these fractures is available that is based on the "metaphysis, epiphysis, ulna" (MEU) classification and the "patient, accident, fracture" (PAF) system. It makes it possible to understand the injury and select the best treatment.

INTRODUCTION: Costochondral grafts have long been used in maxillofacial reconstruction, but have been little used in trauma and orthopedic cases. This surgical technique requires that a graft be harvested from the thorax in the area of the eighth rib. Pleuropulmonary complications are very rare. Although the harvesting technique is simple, it needs to be demystified. GOAL OF STUDY: This study was performed to define anatomical relationships in the eighth costochondral junction and identify topographical and anatomical landmarks that will make it easier to harvest this structure. METHOD: This was a two-part study. First, an anatomical study was carried out on human cadaver thoraxes to define topographical landmarks and study the anatomical surroundings of the eighth costochondral junction. Second, an imaging study was performed using a database of existing patient computed tomography (CT) scans of the chest and abdomen to confirm the topographical landmarks defined in the first part of the study. The spine was used as a reference for both studies. The location of the eighth costochondral junction was defined relative to the spinal processes along with its location on the lower rib cage hemiperimeter in the transverse plane starting at the corresponding spinous process. RESULTS: The eighth costochondral junction was in line with the spinal process of the twelfth thoracic vertebra in the vast majority of cases and located at two-thirds of the lower rib cage hemiperimeter from the posterior median sulcus, regardless of the patient's chest shape, age and gender. This junction was always located under a single muscle (external oblique) and protected by a thick perichondrium layer, which separates it from the intercostal pedicles, endothoracic fascia and parietal pleura. DISCUSSION: This two-part study has identified reliable landmarks for harvesting of an osteochondral graft at the eighth costochondral junction and, by describing its anatomical surroundings, helps take the mystery out of its harvesting. These landmarks were identified in supine cadavers and in free-breathing patients lying in supine for the CT portion. This position must be used when identifying these landmarks in a patient undergoing costochondral autograft harvesting for cartilage reconstruction.

High-energy injuries to the wrist gather complex fractures of the distal radius, radiocarpal dislocations, perilunate dislocations, and other intracarpal dislocations. Depending on the energy of the injury and the position of the wrist at the time of impact, the patient, often a young male with a high functional demand, presents one of these injuries associating fracture(s) and ligament injury. The trauma is often bilateral, with proximal lesions (elbow) very often associated with contusion or compression of the median nerve. Diagnosis is confirmed by wrist X-rays, which are sufficient to determine treatment for radiocarpal and perilunate dislocations. In cases of distal radius fractures or other intracarpal dislocations, a preoperative CT is necessary. Reduction of the dislocation and relief of neurovascular compression are performed immediately. The final treatment of each lesion (bone fixation, ligament repair) can be undertaken simultaneously or delayed, depending on the patient and the lesions. Cartilage lesions, resulting from the high-energy injury, can be estimated using arthroscopy but cannot be repaired and determine the prognosis. The surgeon's objective is to restore joint congruence, which does not prevent stiffness, the main complication of these rare injuries, which the surgeon must know how to recognize and treat.

This case report features a patient with chronic bilateral compartment syndrome of the thenar muscles, which had appeared spontaneously 8 years earlier. The condition was progressive and symptoms recently had become worse. Pressure measurements were performed three times to establish the diagnosis: before, immediately after and 10 minutes after hand exertion. Pain relief was achieved by performing a fasciotomy of the right thenar compartment.

PURPOSE: The primary purpose of this study was to define the size of the trapezium bone through measurements on cadaver specimens and CT scans of living subjects. The secondary purpose of this study was to determine if any correlation existed between the size of the trapezium and local anatomical parameters. METHODS: The radio-ulnar length (L), dorsopalmar width (â) and height (h) of the distal surface of the trapezium were measured by two independent observers on 20 cadaver specimens. The same measurements were carried out by two other observers on anonymized CT scans from 18 patients. The inter- and intra-observer agreement was determined using the intraclass correlation coefficient. RESULTS: In the cadavers, the mean length, width and height of the trapezium were 22.8, 15.5 and 15.2 mm, respectively. On the CT scans, these same dimensions were 19.2, 11.4 and 11.6 mm. Inter-observer agreement was statistically significant in both parts of the study. DISCUSSION: The dimensions of the trapezium bone were about 3.33 mm larger in cadavers than on CT scans. These differences can be explained partially by a systematic under-sizing error on the CT scans and the fact that the cartilage layer cannot be directly visualized. CONCLUSION: This study was able to define the dimensions of the trapezium bone. It may be possible to predict the trapezium height from the length of the forearm or the width of the radial epiphysis. Our data can be used to adjust the size of trapezium implants to the dimensions of the patient's bone.

Rupture of the extensor pollicis longus (EPL) tendon in the wrist is a delayed complication that can occur after wrist injury. Several etiology-related hypotheses have been made to explain these ruptures. The one most commonly accepted is necrosis at the musculotendinous junction of the EPL, which is compressed between the extensor retinaculum and dorsal aspect of the radius. To confirm this hypothesis, we performed an anatomical study to show the close relationship between the extensor retinaculum and the musculotendinous junction of the EPL muscle. We calculated the distance between the musculotendinous junction of the various finger extensor muscles and the proximal edge of the extensor retinaculum. We were able to show that this junction is located under the extensor retinaculum for the extensor indicis (EI) and EPL muscles, but the latter is in the third extensor compartment, which is a tight, confined space. Any pressure increase in this space following trauma, for example, can bring about compartment syndrome at this musculotendinous junction, which some authors have found to be poorly vascularized.

In patients for whom function is a priority, anatomic reduction and stable fixation are prerequisites for good outcomes. Several therapeutic options exist, including orthopedic treatment and internal fixation with pins (intra- and extrafocal), external fixation which may or may not bridge the wrist, and different internal fixation techniques with dorsal or palmar plates using or not, locking screws. Arthroscopy may be necessary in case of articular fracture. In the presence of significant metaphyseal bone defects, filling of the comminution with phosphocalcic cements provides better graft stability. The level of evidence is too low to allow recommending one type of fixation for one type of fracture; and different fixation options to achieve stable reduction exist, each with its own specific complications. With the new generations of palmar plate, secondary displacement is becoming a thing of the past.
